Description

Air conditioner

Technical Field

The utility model relates to an air conditioner, this air conditioner has the opening and closing board that can open and close the opening of casing main part.

Background

Generally, a casing of an air conditioner has a suction grill that sucks air into the casing. A filter for capturing dust is provided inside the suction grill, and the filter is periodically cleaned to remove the captured dust from the filter. Therefore, in a typical air conditioner, in order to easily remove the filter from the suction grill or the casing body at the time of cleaning, the suction grill is supported by the casing body so as to be openable and closable.

For example, in an air conditioner described in japanese patent laid-open publication No. 2000-088278 (patent document 1), in order to prevent an operator from mistakenly inserting a hand into the casing through an opening when opening the suction grill, a structure is employed in which the movement of the suction grill in the opening direction is restricted to a predetermined opening degree. Specifically, a U-shaped member having a pair of rail portions and a connecting portion connecting end portions of the pair of rail portions is attached to a suction grill of the air conditioner. A columnar locking bar provided in the housing body is provided in the elongated hole between the pair of rail portions. The rail portions are provided with protrusions facing each other. Then, in a closed state where the suction grill covers the opening of the casing body, the locking rod abuts against each of the protrusions, thereby restricting the movement of the suction grill in the opening direction.

However, in the air conditioner as disclosed in patent document 1, when the opening and closing of the opening and closing plate such as the suction grill is repeated during long-term use, one or both of the locking rod and the protrusion may be worn out by friction between the locking rod and the protrusion, and the movement of the suction grill in the opening direction may be insufficiently restricted, and the opening and closing plate may be opened arbitrarily. In order to solve such a problem, a countermeasure may be taken in which a slide type lock mechanism is separately provided as disclosed in, for example, japanese patent laid-open publication No. 2008-064342 (patent document 2) and japanese patent laid-open publication No. 2010-261608 (patent document 3).

However, if the air conditioner described in patent document 1 is further added with the slide type lock mechanisms as in patent documents 2 and 3, it is necessary to add not only the slide type lock piece (slide lever) but also the design change of the casing main body and the design change of the suction grill (opening/closing plate). Since the size of the casing main body and the size of the suction grill are large, the cost is greatly increased particularly in terms of equipment investment and the like.

SUMMERY OF THE UTILITY MODEL

An object of the present invention is to provide an air conditioner capable of restricting the movement of an opening/closing plate in an opening direction to a predetermined opening degree and suppressing the problem of the opening/closing plate being opened at will due to long-term use at low cost.

The utility model discloses an air conditioner includes: a housing main body having an opening; an opening/closing plate attached to the case main body so as to be capable of opening and closing the opening; a guide member supported by the opening/closing plate, guiding the opening/closing plate in an opening direction and a closing direction of the opening/closing plate, and restricting further movement of the opening/closing plate in the opening direction when the opening/closing plate is in an open state in which a predetermined opening degree is reached; a plate fixing member that restricts movement of the opening/closing plate in the opening direction when the opening/closing plate is in a closed state covering the opening; wherein the guide member has an engaging surface facing the opening direction, the plate fixing member is supported by the housing main body so as to be slidable in a direction parallel to the engaging surface, the plate fixing member has an opposing surface facing the engaging surface in the opening direction based on the plate fixing member being slid in a first direction when the opening/closing plate is in the closed state, and the opposing surface is moved to a position not facing the engaging surface in the opening direction based on the plate fixing member being slid in a second direction opposite to the first direction.

According to the utility model discloses an air conditioner, can be with the removal of shutter to the opening direction restriction at appointed aperture and the phenomenon that the shutter is opened at will because of long-term use appearance can be restrained to the low cost.

Detailed Description

An air conditioner 10 according to an embodiment of the present invention will be described below with reference to the drawings.

(Structure of air conditioner)

As shown in fig. 1 (a) and (B), the air conditioner 10 is a floor-standing indoor unit and has a vertically long rectangular parallelepiped casing 12. The blower 31, the electronic device housing portion 33, the heat exchanger 35, and the like are housed in the casing 12.

The casing 12 includes a casing main body 13 having an opening 11, and an intake grill 15 as an opening/closing plate. The opening 11 is provided at a lower portion of the front surface of the housing body 13 and is rectangular in front view. The suction grill 15 has a rectangular shape in front view and has a size covering the opening 11 of the casing body 13. The suction grill 15 is detachable from the casing body 13 so as to open and close the opening 11.

The casing body 13 has an air outlet 37 at an upper portion of the front surface. A plurality of flaps for changing the wind direction are attached to the air outlet 37. A detachable filter 16 is attached to the back surface of the suction grill 15. The filter 16 is supported by an unillustrated filter frame formed on the rear surface of the suction grill 15. The casing body 13 has a front plate 136, a pair of side plates, a top plate, a bottom plate, and a back plate, which are positioned between the opening 11 and the air outlet 37.

The blower 31 is provided at a lower portion in the casing main body 13 and is located on the back side of the suction grill 15. The blower 31 is a centrifugal blower, and includes an impeller 31a, a casing 31b accommodating the impeller 31a, and a motor 31c for rotating the impeller 31 a. The air intake of the blower 31 faces the front. The electronic device housing portion 33 is provided near an upper edge 131 of the opening 11 of the case main body 13. Since the electronic device housing portion 33 is exposed to the outside through the opening 11 when the suction grill 15 is removed from the housing body 13, maintenance, various settings, and the like can be performed.

The lower end of the heat exchanger 35 is located near the center of the casing body 13 in the height direction, and the upper end of the heat exchanger 35 is located near the ceiling of the casing body 13. The heat exchanger 35 is provided in an inclined state in the casing body 13 so that the lower end portion is positioned on the front surface side and the upper end portion is positioned on the rear surface side. When the impeller 31a is rotated by the driving of the motor 31c of the blower 31, the air in the room is sucked into the casing 12 through the gaps between the fences of the suction grill 15, rises in the casing 12, exchanges heat with the cooling medium at the heat exchanger 35, and is blown out into the room from the blow-out port 37.

The suction grill 15 can be set in three states, namely, a closed state (see fig. 2 a) which is a state during operation of the air conditioner 10, an open state (see fig. 2B) which is a state when the filter 16 is attached and detached, and a detached state (see fig. 2C) which is a state when various settings are made in the electronic equipment housing unit 33.

As shown in fig. 2 (a) to (C), the lower edge 132 of the opening 11 of the case main body 13 has a groove extending in the width direction of the case main body 13. The lower edge 151 of the suction grill 15 has a flat plate-like fitting piece that can be fitted into the groove of the lower edge 132 of the casing body 13. When the suction grill 15 is in the closed state and the open state, the fitting pieces of the lower edge portion 151 of the suction grill 15 are fitted into the grooves of the lower edge portion 132 of the casing main body 13. Each state is described in detail later.

(opening and closing structure of suction grille)

As shown in fig. 4 (a) and (B), the case main body 13 includes a pair of extending pieces 133 and 133 extending downward from the upper edge 131 of the opening 11. These extending pieces 133, 133 are provided on both sides of the upper edge 131 of the opening 11 (both sides of the lower portion of the front panel 136). In fig. 4 (a) and (B), only the extending piece 133 located on the right side toward the front is illustrated. Each extension piece 133 has a rectangular through hole 134 penetrating in the opening/closing direction. A corresponding guide member 17 is inserted through each through-hole 134. Each extension piece 133 has a columnar portion 21 extending in the horizontal direction between the inner side surfaces on both sides of the through-hole 134.

The air conditioner 10 includes a pair of guide members 17, 17 and a pair of plate fixing members 19, 19. As shown in fig. 1 (a), a pair of guide members 17, 17 are mounted on corners of both sides of an upper portion of the suction grill 15. These guide members 17, 17 guide the suction grill 15 between the closed state and the open state in the opening direction D1 and the closing direction D2 of the suction grill 15. When the suction grill 15 is in the open state with the predetermined opening degree, the guide members 17 and 17 restrict further movement of the suction grill 15 in the opening direction D1.

Since the pair of guide members 17, 17 have a bilaterally symmetrical structure and the pair of plate fixing members 19, 19 have a bilaterally symmetrical structure, the structures of the guide member 17 and the plate fixing member 19 located on the right side in front will be described below.

As shown in fig. 3 (a), (B) and 4 (a), (B), the guide member 17 includes a pair of rail portions (first rail portion 171, second rail portion 172) extending in the closing direction D2 with the columnar portion 21 interposed therebetween, and a connecting portion 173 connecting distal end portions of these rail portions 171, 172 to each other. The first rail portion 171 is substantially parallel to the second rail portion 172 and is located above the second rail portion 172. The guide member 17 has a U-shape, and a gap (long hole) extending in the opening/closing direction is provided between the first rail portion 171 and the second rail portion 172.

The guide member 17 has a protrusion 174. The protrusion 174 includes a first protrusion 174a and a second protrusion 174 b. The first protrusion 174a protrudes downward from the lower surface of the first rail 171 toward the second rail 172. The second protrusion 174b protrudes upward from the upper surface of the second rail portion 172 toward the first rail portion 171. These projections 174a, 174b are opposed to each other in a state where their distal end portions are close to or abut against each other, thereby locally reducing the gap between the pair of rail portions 171, 172. The local small gap is smaller than the width of the columnar portion 21 (the diameter of the columnar portion 21 in the case where it is cylindrical).

Each of the projections has a side in a substantially triangular shape or a substantially circular arc shape, for example, and the surface in contact with the columnar portion 21 is an inclined surface or a curved surface. That is, in the region where the protrusion 174 is provided, the gap between the pair of rail portions 171 and 172 gradually decreases toward the closing direction D2, and is smallest at a position where the distal end portions of the protrusions 174a and 174b face each other. Further, the gap gradually increases from this position toward the closing direction D2.

The first rail 171 has a rib 175 extending upward from the first rail 171. As shown in fig. 5a, the rib 175 includes a pair of wall portions (a first wall portion 175a and a second wall portion 175b) and a wall portion (a third wall portion 175c) connecting the pair of wall portions. The first wall portion 175a and the second wall portion 175b are provided on both sides of the upper surface of the first rail portion 171 in the width direction. The first wall portion 175a and the second wall portion 175b extend upward in a rib shape in a posture substantially parallel to the longitudinal direction (opening/closing direction) of the first rail portion 171. The third wall portion 175c connects edges on the opening direction D1 side of the pair of wall portions 175a, 175b to each other. The third wall 175c is orthogonal to the longitudinal direction. The first wall portion 175a and the second wall portion 175b are substantially triangular in side view, and the third wall portion 175c is rectangular in front view. The third wall 175c has an engaging surface 17a facing the opening direction D1. The engaging surface 17a is a plane substantially entirely orthogonal to the longitudinal direction.

The rib 175 is provided at the same position as the protrusion 174 in the longitudinal direction (opening/closing direction) of the first rail 171. Here, "the same position" means that at least a part of the protrusion 174 is located between the end of the rib 175 in the opening direction D1 and the end of the rib 175 in the closing direction D2 in the longitudinal direction. In the present embodiment, the protrusion 174 is located substantially midway in the longitudinal direction between the end of the rib 175 in the opening direction D1 and the end in the closing direction D2.

As shown in fig. 5 (B), the first rail 171 has a base end fixing portion 176 extending from the vicinity of the lower end of the locking surface 17a in the opening direction D1 at a position closer to the opening direction D1 than the locking surface 17a of the rib 175. The first rail portion 171 is longer than the second rail portion 172 by the base end fixing portion 176 in the opening direction D1. As shown in fig. 4 (a) and (B), the base end fixing portion 176 is fixed to the screw portion 153 provided at the corner of the upper portion of the suction grill 15. The screw portion 153 has a female screw 153a extending in the vertical direction. The base end fixing portion 176 has a through hole 17b penetrating in the vertical direction.

The guide member 17 is fixed to the suction grill 15 by screwing a screw B inserted through the through hole 17B into the internal thread 153a of the screw portion 153. When the suction grill 15 is removed from the housing main body 13, the screw B may be removed from the screw portion 153. In other words, the guide member 17 is fixed to the suction grill 15 unless the screw B screwed to the screw portion 153 is removed. Therefore, the opening degree of the suction grill 15 can be prevented from becoming larger than the open state unintentionally.

As shown in fig. 4 (B), the end of the second rail portion 172 in the opening direction D1 is provided on the lower edge 134a of the through-hole 134 and is not fixed to the suction grill 15. That is, since only the base end portion of the first rail portion 171 of the U-shaped guide member 17 is supported by the suction grill 15, the first rail portion 171 and/or the second rail portion 172 are easily elastically deformed (flexibly deformed). The degree of elastic deformation is adjusted to such a degree that the columnar portion 21 can pass between the protrusions 174a and 174b, which will be described later. In the closed state shown in fig. 4 (B), the end portion of the second rail portion 172 in the opening direction D1 is sandwiched between the lower edge 134a of the through-hole 134 and the columnar portion 21 in the vertical direction. In the present embodiment, the guide member 17 is configured such that only the base end portion of the first rail portion 171 is supported by the suction grill 15, but both the base end portion of the first rail portion 171 and the base end portion of the second rail portion 172 may be supported by the suction grill 15.

As shown in fig. 6 (a) and (B), the plate fixing member 19 restricts the movement of the suction grill 15 in the opening direction D1 when the suction grill 15 is in the closed state covering the opening 11. The plate fixing member 19 is supported by the housing body 13 so as to be slidable in a direction parallel to the locking surface 17a of the guide member 17.

The board fixing member 19 is provided on a corner of a lower portion of the front panel 136 of the housing main body 13. A rectangular through hole 137a that is long in the vertical direction is formed in the side edge portion 137 of the front panel 136. The plate fixing member 19 is supported on the inner surface of the side edge 137 by a support member, not shown, so as to be slidable in the vertical direction.

As shown in fig. 5 (a) and (B), the plate fixing member 19 includes a member body 193 extending along the inner surface of the side edge 137, a first extending portion 194, a second extending portion 195, a slide restricting portion 191, and an operating portion 192. The first extension 194 extends from the lower end of the member main body 193 along the upper edge 131 of the housing main body 13. The second extension 195 extends downward from the distal end of the first extension 194. The slide restricting portion 191 extends further upward from the upper end of the member body 193. The operation portion 192 protrudes laterally from the member body 193 and is fitted into the through hole 137a of the skirt portion 137.

An engaging protrusion 138 that protrudes inward in the width direction and engages with the slide restricting portion 191 is provided on the inner surface of the side edge portion 137. The operation portion 192 protrudes laterally from the through hole 137a of the side edge portion 137, and is operated by the operator to slide in the vertical direction. Thereby, the plate fixing member 19 slides in the vertical direction with respect to the housing main body 13.

The second extending portion 195 has an opposing face 19a on the closing direction D2 side. The opposing surface 19a is a plane substantially entirely orthogonal to the longitudinal direction and is substantially parallel to the locking surface 17 a. As shown in fig. 5 (a) and 6 (a), the second extension 195 is provided at a position where it can enter and exit the through hole 134 of the extension piece 133 in accordance with the sliding movement of the plate fixing member 19.

The slide restricting portion 191 has: a step portion 191c that is bent from the upper end of the member body 193 in a direction away from the inner surface of the side edge portion 137 (inward in the width direction of the housing body 13); a flexible piece 191a extending upward from the distal end of the stepped portion 191 c; an engaging claw portion 191b protrudes from an upper end of the flexible piece 191a toward an inner surface of the side edge portion 137. The engaging pawl portion 191b has a substantially triangular shape in front view. The upper and lower surfaces of the engaging claw 191b that abuts against the engaging projection 138 are inclined surfaces that are easily engaged with the engaging projection 138 and easily disengaged from the engaging projection 138 due to elastic deformation of the flexible piece 191 a.

Fig. 5 (a) and (B) show a state in which the plate fixing member 19 is located at the upper limit position (restriction release position) of the sliding movement, and fig. 6 (a) and (B) show a state in which the plate fixing member 19 is located at the lower limit position (restriction position) of the sliding movement.

As shown in fig. 5 (a) and (B), at the upper limit position, the downward movement of the plate fixing member 19 is restricted based on the engagement claw portion 191B being located above the engagement projection 138 and engaging with the engagement projection 138. In the upper limit position, the opposing surface 19a is positioned above the locking surface 17a and does not oppose the locking surface 17a in the opening direction D1, and therefore, the movement restriction of the suction grill 15 in the opening direction D1 by the plate fixing member 19 is released.

As shown in fig. 6 (a) and (B), at the lower limit position, the engagement with the engagement projection 138 is released based on the engagement claw portion 191B being located below the engagement projection 138, and the downward movement restriction of the plate fixing member 19 is released. In the lower limit position, since a part of the opposing surface 19a (lower portion of the opposing surface 19 a) and the locking surface 17a face each other in the opening direction D1, the plate fixing member 19 restricts the movement of the suction grill 15 in the opening direction D1. In the lower limit position, the suction grill 15 is in the closed state, the protrusion 174 abuts on the columnar portion 21, and the opposing surface 19a and the locking surface 17a are spaced apart from each other by a predetermined distance. That is, a gap is provided between the opposing surface 19a and the locking surface 17a in the opening/closing direction.

(opening and closing operation of suction grille)

As shown in fig. 2 (a), in the closed state, the suction grill 15 covers the entire opening 11 of the casing body 13. In this closed state, the edge portions 154 and 154 (see fig. 1 a) on both sides of the suction grill 15 abut against the edge portions 135 and 135 on both sides of the opening 11 of the housing main body 13, respectively. Thereby, further movement of the suction grill 15 in the closing direction D2 is restricted. In the closed state, the movement of the suction grill 15 in the opening direction D1 is restricted by the engagement of the protrusions 174a and 174b of the guide member 17 with the columnar portion 21 provided in the casing main body 13.

The projections 174a and 174b are formed at positions that can pass over the columnar portion 21 when the suction grill 15 is turned from the open state to the closed state. The projections 174a and 174b are formed at positions that, when in the closed state across the columnar portion 21, abut against the columnar portion 21 to hold the closed state of the suction grill 15.

In the closed state, as shown in fig. 6 (a) and (B), since the plate fixing member 19 is located at the lower limit position, even when the projections 174a and 174B are worn due to long-term use of the air conditioner 10 and the projections 174a and 174B and the columnar portion 21 cannot be sufficiently engaged with each other, the movement of the suction grill 15 in the opening direction D1 is restricted by the plate fixing member 19.

Next, the operation of the suction grill 15 when it is changed from the closed state to the open state will be described. First, as shown in fig. 5 (a), the operator operates the operation unit 192 to slide the plate fixing member 19 upward, and causes the engaging claw 191b to engage with the engaging protrusion 138. Thereby, the opposing surface 19a moves to a position not opposing the locking surface 17a in the opening direction D1.

Next, the operator grips the vicinity of the upper end of the side edge 154 of the suction grill 15 and pulls out the suction grill 15 in the near direction (opening direction D1). This releases the engagement of the columnar portion 21 with the projection 174. In the engaged state before the engagement is released, as shown in fig. 2 (a) and 3 (a), columnar portion 21 is positioned further in opening direction D1 than projection 174 and abuts projection 174. In the state where the engagement is released, the columnar portion 21 is positioned in the closing direction D2 with respect to the protrusion 174.

At this time, the columnar portion 21 can pass through the gap between the protrusions 174a and 174b due to elastic deformation of at least one of the columnar portion 21, the first protrusion 174a, the second protrusion 174b, the first rail portion 171, and the second rail portion 172.

When the operator further pulls out the suction grill 15 in the opening direction D1, the columnar portion 21 comes into contact with the inner surface of the connection portion 173 as shown in fig. 2 (B) and 3 (B), and the suction grill 15 is opened.

In the process of moving the suction grill 15 from the closed state to the open state, the suction grill 15 is pulled out in the opening direction D1 with the lower edge portion 151 of the suction grill 15 as a fulcrum in a state where the fitting piece (lower edge portion 151) of the suction grill 15 is fitted in the groove (lower edge portion 132) of the casing body 13.

As shown in fig. 2 (B), in the open state, a predetermined gap is formed between the upper edge 152 of the suction grill 15 and the upper edge 131 of the opening 11 of the housing main body 13. In this open state, the suction grill 15 is at an angle α to the front panel 136 of the housing main body 13. In the opened state, the filter 16 is attached to the suction grill 15 by a filter frame inserted from above into the back surface of the suction grill 15. The filter 16 is pulled out upward with respect to the filter frame, and is removed from the suction grill 15.

Next, the operation of the suction grill 15 when it is detached from the open state will be described. First, the operator removes the screw B from the screwing portion 153 using a tool such as a screwdriver. Thus, the suction grill 15 is not restricted by the casing body except for the lower edge 151 thereof being fitted to the lower edge 132 of the opening 11 of the casing body 13.

Next, as shown in fig. 2 (C), the operator pulls out the suction grill 15 in the opening direction D1 with the lower edge portion 151 as a fulcrum to such an extent that the suction grill 15 forms an angle β with the front plate 136 of the casing main body 13, and then pulls up the suction grill 15 diagonally upward. Thereby, the engagement between the lower edge 151 of the suction grill 15 and the groove of the lower edge 132 is released, and the suction grill 15 is removed from the casing main body 13.

As shown in fig. 3 (a) and 4 (B), retaining projections 177 and 177 for preventing the guide member 17 from coming off the through-hole 134 in a state where the guide member 17 is released from being engaged with the suction grill 15 are formed on both side surfaces of the first rail portion 171 of the guide member 17.

As described above, the opening and closing operation of the suction grill 15 has been described, but the operation of attaching the detached suction grill 15 to the casing body 13 and the operation of setting the opened state to the closed state need only be the reverse of the above-described operation, and therefore, a detailed description thereof is omitted.

(modification example)

Fig. 7 (a) and (B) and fig. 8 (a) and (B) are diagrams showing modifications of the air conditioner 10. In this modification, the second extending portion 195 of the plate fixing member 19 has the opposing surface 19a and the projecting portion 19b projecting from the opposing surface 19a in the closing direction D2.

The projection 19b is provided at a position facing the locking surface 17a in the opening direction D1 when the plate fixing member 19 is at the lower limit position. In this modification, at the lower limit position, the opposing surface 19a of the second extending portion 195 and the locking surface 17a are separated from each other with a predetermined gap, and the protrusion 19b abuts on the locking surface 17 a. Therefore, in this modification, the movement of the suction grill 15 in the opening direction D1 is more reliably suppressed, and the rattling or the like of the suction grill 15 is suppressed, compared to the embodiments shown in fig. 5 (a) and (B) and fig. 6 (a) and (B) that do not have the projection 19B.

The protrusion 19b is preferably formed of an elastically deformable material. In this case, in the process of slidably moving the plate fixing member 19 from the upper limit position shown in fig. 7 (a) and (B) to the lower limit position shown in fig. 8 (a) and (B), the projection 19B is elastically deformed at the time when the projection 19B contacts the upper end of the rib 175. Thereby, the sliding movement of the plate fixing member 19 is smooth.

The projection dimension of the projection 19b in the closing direction D2 is preferably larger than the gap between the locking surface 17a and the facing surface 19a at the lower limit position. This can further suppress the movement of the suction grill 15 in the opening direction D1.

In addition, in this modification, as described above, by providing the projection 19b, the rattling of the suction grill 15 in the closed state is suppressed. Therefore, the protrusions 174a and 174b of the guide member 17 may be omitted.

As described above, in the present embodiment, the opening degree of the opening/closing plate 15 can be limited to a desired size, the locking surface 17a is provided on the guide member 17, the plate fixing member 19 slidably supported on the housing main body 13 is provided, and the movement of the opening/closing plate 15 in the opening direction D1 is limited by the facing surface 19a of the plate fixing member 19 facing the locking surface 17 a. This can suppress the opening and closing plate 15 from being opened arbitrarily. In addition, in the present embodiment, it is not necessary to change the design of both the case body and the opening/closing plate, which are large in size as in the conventional case, and the design of the opening/closing plate 15 can be maintained as in the conventional case. Therefore, the opening degree of the opening/closing plate 15 can be limited at low cost.

In the present embodiment, in addition to the movement restriction of the opening/closing plate 15 by the plate fixing member 19, the movement of the opening/closing plate 15 in the opening direction D1 can be restricted by the engagement of the protrusion 174 provided on the guide member 17 with the columnar portion 21 provided on the case main body 13.

In the present embodiment, the movement restricting structure realized by the engagement of the columnar portion 21 and the projection 174 is designed such that the columnar portion 21 and the projection 174 abut against each other in the closed state, and the movement restricting structure realized by the opposing surface 19a and the locking surface 17a is designed such that the opposing surface 19a and the locking surface 17a do not abut against each other but are separated from each other in the closed state. Since the latter is a structure in which surfaces face each other, if the design in which the columnar portions 21 and the projections 174 abut each other in the closed state is adopted, there is a possibility that the surfaces face each other due to a dimensional error, and in the former, even if the design in which the columnar portions 21 and the projections 174 abut each other in the closed state is adopted, the dimensional error can be absorbed to some extent.

In particular, when the columnar portion has a cylindrical shape, the range of the dimensional error can be further expanded because the curved surface of the columnar portion 21 abuts the projection 174. In addition, when the contact surface of the protrusion 174 is a curved surface or an inclined surface, the curved surface of the columnar portion 21 and the curved surface or the inclined surface of the protrusion 174 are in contact with each other, and therefore, the range of the dimensional error can be allowed to be further expanded.

In the present embodiment, since the locking surface 17a is provided on the rib 175, in the closed state where the locking surface 17a faces the opposing surface 19a, the rigidity necessary for restricting the movement of the opening/closing plate 15 by the locking surface 17a can be ensured. Further, the rib 175 is provided at substantially the same position as the protrusion 174, so that the rigidity of the rail portions 171 and 172 at the portion where the protrusion 174 is provided can be increased. Therefore, excessive elastic deformation of the rail portions 171 and 172 at the portions where the projections 174 are provided can be suppressed, and the gap between the projections 174 and the rail portions 172 can be appropriately maintained over a long period of time. This can maintain the engagement state between the protrusion 174 and the columnar portion 21 well for a long period of time.

In the present embodiment, since the sliding movement of the panel fixing member 19 can be restricted by the slide restricting portion 191, the panel fixing member 19 can be suppressed from being arbitrarily slid and moved other than in the closed state.

The above embodiments mainly include the following embodiments.

(1) The utility model relates to an air conditioner includes: a housing main body having an opening; an opening/closing plate attached to the case main body so as to be capable of opening and closing the opening; a guide member supported by the opening/closing plate, guiding the opening/closing plate in an opening direction and a closing direction of the opening/closing plate, and restricting further movement of the opening/closing plate in the opening direction when the opening/closing plate is in an open state in which a predetermined opening degree is reached; a plate fixing member that restricts movement of the opening/closing plate in the opening direction when the opening/closing plate is in a closed state covering the opening; wherein the guide member has an engaging surface facing the opening direction, the plate fixing member is supported by the housing main body so as to be slidable in a direction parallel to the engaging surface, the plate fixing member has an opposing surface facing the engaging surface in the opening direction based on the plate fixing member being slid in a first direction when the opening/closing plate is in the closed state, and the opposing surface is moved to a position not facing the engaging surface in the opening direction based on the plate fixing member being slid in a second direction opposite to the first direction.

According to this configuration, the opening degree of the opening/closing plate can be restricted to a desired size, the guide member is provided with the engaging surface, and the plate fixing member slidably supported by the housing main body is provided, and the movement of the opening/closing plate in the opening direction is restricted by the opposing surface of the plate fixing member opposing the engaging surface. This can suppress the opening/closing plate from being opened arbitrarily. Further, according to this configuration, it is not necessary to change the design of both the case body and the opening/closing plate, which are large in size as in the conventional case, and the design of the opening/closing plate can be maintained as in the conventional case.

(2) In the air conditioner, it is preferable that the casing body is provided with a columnar portion extending in a direction intersecting with an opening/closing direction of the opening/closing plate, and the guide member includes: a pair of rail portions, a base end portion of which is supported by the opening/closing plate and extends in the closing direction via the columnar portion; a connecting portion connecting portions on distal end sides of the pair of rail portions to each other; wherein at least one of the pair of rail portions has a protrusion portion protruding from the rail portion toward the other so that a gap between the pair of rail portions is locally smaller than a width of the columnar portion, the columnar portion is capable of passing through a gap between the protrusion portion and the other by elastic deformation of at least one of the columnar portion, the protrusion portion, the one, and the other, in the closed state, movement of the opening/closing plate in the closing direction is regulated based on a part of the opening/closing plate abutting on the case main body, and movement of the opening/closing plate in the opening direction is regulated based on the columnar portion abutting on the protrusion portion at a position in the opening direction higher than the protrusion portion, and in the open state, when the opening/closing plate reaches the preset opening degree, movement of the opening/closing plate in the opening direction is regulated based on the columnar portion abutting on the connection portion And (6) moving.

According to this configuration, in addition to the movement of the opening/closing plate being regulated by the plate fixing member, the movement of the opening/closing plate in the opening direction can be regulated by the engagement of the protrusion provided on the guide member with the columnar portion provided on the case main body.

(3) When the components such as the case body, the opening/closing plate, the plate fixing member, and the guide member are used, a dimensional error in manufacturing cannot be avoided. Therefore, in the air conditioner, it is preferable that the facing surface and the locking surface are separated from each other in the closed state and in a state where the facing surface and the locking surface face each other in the opening direction.

According to this configuration, in the two movement restricting structures described in (2), the movement restricting structure in which the columnar portion is engaged with the protrusion is designed such that the columnar portion is brought into contact with the protrusion in the closed state, and in the movement restricting structure in which the opposing surface and the locking surface are realized, the opposing surface and the locking surface are not brought into contact with each other and are separated from each other in the closed state. Since the latter is a structure in which the surfaces face each other, if the design in which the surfaces are brought into contact with each other in the closed state is adopted, there is a possibility that the surfaces cannot be brought into contact with each other due to a dimensional error, and in the former, even if the design in which the surfaces are brought into contact with each other in the closed state is adopted, the dimensional error can be absorbed to some extent due to engagement between the columnar portion and the protrusion portion.

(4) In the air conditioner, it is preferable that the guide member has a rib extending from the one member in a direction intersecting the opening/closing direction, the locking surface is provided on the rib, and the rib is provided at the same position as the protrusion in the opening/closing direction.

According to this configuration, since the engaging surface is provided on the rib, the rigidity necessary for restricting the movement of the opening/closing plate by the engaging surface can be ensured in the closed state where the engaging surface and the opposing surface face each other. Further, since the rib is provided at the same position as the projection, the rigidity of the rail portion of the portion where the projection is provided can be increased, and therefore, excessive elastic deformation of the rail portion of the portion where the projection is provided can be suppressed, and the gap between the projection and the rail portion can be appropriately maintained for a long period of time. This can maintain the engagement state between the protrusion and the columnar portion well for a long period of time.

(5) In the air conditioner of the present invention, it is preferable that the plate fixing member has a slide restricting portion for restricting a sliding movement of the plate fixing member by engaging with the housing main body, and the slide restricting portion engages with the housing main body when the opposite surface moves to a position not opposed to the locking surface in the opening direction and is in a state where a movement restriction of the opening/closing plate to the opening direction is released.

According to this configuration, since the sliding movement of the panel fixing member can be restricted by the slide restricting portion, the panel fixing member can be prevented from being arbitrarily slid and moved other than in the closed state.

While the present embodiment has been described above with reference to the accompanying drawings, the present embodiment is not limited to these embodiments, and various changes, modifications, and the like can be made without departing from the spirit and scope of the invention.

In the above embodiment, the case where the air conditioner is a floor type is described as an example, but the present invention can be applied to other types of air conditioners such as a ceiling type air conditioner, a ceiling embedded type air conditioner, and a wall-mounted type air conditioner.

In the above embodiment, the case where the first protrusion 174a is provided on the first rail portion 171 and the second protrusion 174b is provided on the second rail portion 172 has been described as an example, but one or both of the protrusions 174a and 174b may be omitted in the present invention.

In the above embodiment, the case where the opposing surface 19a and the locking surface 17a are separated from each other in the closed state has been described as an example, but the present invention is not limited to this. The opposing surface 19a may abut against the locking surface 17a in the closed state.

In the above embodiment, the rib 175 is provided at the same position as the protrusion 174 in the opening/closing direction, but the present invention is not limited to this. The rib 175 may be provided at a position offset from the protrusion 174 in the opening/closing direction.

In the above embodiment, the case where the plate fixing member 19 slides in the vertical direction is exemplified, but the present invention is not limited thereto.
