Description

  The present invention relates to a floor-mounted air conditioner.

First, a conventional floor-mounted air conditioner will be described.
FIG. 5 is a schematic cross-sectional view of a conventional floor-mounted air conditioner. With reference to FIG. 5, the floor-mounted air conditioner 1 </ b> C mainly includes a casing 10, a blower 41 and an indoor heat exchanger 40 arranged in the casing 10. The casing 10 has a front panel 11, a back panel 12, a top panel 13, and a bottom panel 14. The front panel 11 is provided with a suction port 20 for sucking indoor air into the casing 10. Further, the casing 10 is provided with an air outlet 21 for blowing out the introduced air to the outside of the casing 10.

  Next, the operation of the conventional floor-mounted air conditioner 1C will be described. The floor-mounted air conditioner 1C is installed so that the bottom panel 14 faces the indoor floor. When the blower 41 is operated, air is sucked into the casing 10 through the suction port 20 provided in the front panel 11. Then, the air is blown to the indoor heat exchanger 40 by being guided from the blower 41 to the guide 50. The blown air passes through the indoor heat exchanger 40 and is blown out into the room from the outlet 21.

  A guide 50 is provided to restrict the airflow in the casing 10. A support frame 51 is provided to support the indoor heat exchanger 40.

Such an air conditioner is disclosed in, for example, Japanese Patent Application Laid-Open No. 2001-208366.
JP 2001-208366 A

  As shown in FIG. 5, the conventional floor-mounted air conditioner 1 </ b> C is provided with an air outlet 21 and a suction port 20 on the front panel 11. Since the operation sound of the blower 41 leaks from the air outlet 21 and the suction port 20 to the front side of the floor-mounted air conditioner 1C, there is a problem that the noise in the room where the floor-mounted air conditioner 1C is installed increases.

  Further, since the heat exchanger 40 is interposed between the blower 41 and the blower outlet 21, the discharge air from the blower 41 is rectified after passing through the heat exchanger 40 and blown out from the blower outlet 21. For this reason, arrangement | positioning of the blower outlet 21 will be restrict | limited to the heat exchanger 40 vicinity. Alternatively, even if the air outlet 21 is provided outside the vicinity of the heat exchanger 40, it is difficult to rectify the blown air after passing through the heat exchanger 40, and there is a problem that the air cannot be blown out sufficiently. .

  The present invention has been made in view of the above problems, and its purpose is to suppress floor noise due to leakage of the operating sound of the blower and to send out blown air sufficiently rectified from the outlet. It is to provide an air conditioner.

  The floor-mounted air conditioner includes a casing, a blower outlet, a suction port, a blower, and an indoor heat exchanger. The casing has a front surface and a back surface facing each other, and a bottom surface for installation on the floor, and has a front panel on the front surface. A blower outlet is an opening part provided in the casing. The suction port is an opening provided on the back surface of the casing. The blower is provided in the casing and generates an airflow that enters the casing through the suction port and exits the casing through the blowout port. The indoor heat exchanger is provided at a position in the middle of the airflow path in the casing and at a position upstream of the airflow with respect to the blower.

  According to the floor-mounted air conditioner of the present invention, since the suction port is provided on the back surface of the casing, it is not necessary to provide an opening as a suction port on the front panel. For this reason, the opening area of a front panel can be made small. Therefore, the operation sound of the blower that leaks to the front surface of the floor-mounted air conditioner through the opening of the front panel can be reduced, and the indoor noise caused by the operation sound of the blower can be suppressed.

  The indoor heat exchanger is provided at a position upstream of the airflow with respect to the blower. For this reason, there is no indoor heat exchanger that weakens the momentum of the airflow between the blower and the outlet. Therefore, the airflow can be blown out from the casing toward the room.

  Further, there is no indoor heat exchanger at a position downstream of the airflow with respect to the blower. For this reason, the freedom degree of design of the path | route of the airflow between an air blower and a blower outlet is high. Therefore, the design freedom of the position and size of the air outlet is increased.

  Preferably, in the above-described floor-mounted air conditioner, the air outlet has a plurality of areas, and a damper is provided at a position in the middle of the path of the airflow flowing between at least one of the plurality of areas and the blower. ing.

  Thereby, the airflow which blows off from the at least 1 area | region of a blower outlet can be suppressed.

  In the floor-mounted air conditioner, preferably, the air outlets are provided in an upper region and a lower region of the front surface of the casing.

  This makes it possible to effectively heat the room by blowing air from the lower region into the room particularly during heating.

  In the floor-mounted air conditioner described above, more preferably, the suction port is located approximately in the middle between the upper region and the lower region in the up-down direction.

  Thereby, air can be blown out from both the lower region and the upper region of the outlet in a well-balanced manner.

  As described above, according to the floor-mounted air conditioner of the present invention, there is no need to provide an opening as a suction port on the front panel. For this reason, it becomes possible to reduce the operation sound of the blower that leaks to the front surface of the floor-mounted air conditioner through the opening of the front panel, and the indoor noise caused by the operation sound of the blower is reduced. Moreover, since a heat exchanger is not interposed between the blower and the blower outlet, the air discharged from the blower can be directly rectified and blown out. Further, the air outlet can be arranged at any place without being limited to the vicinity of the heat exchanger, and the air outlet can be provided not only at the upper part of the casing but also at the lower part of the casing. Further, not only the top and bottom but also the left and right and the top and bottom and the left and right can be provided with air outlets.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view schematically showing the configuration of a floor-standing air conditioner according to an embodiment of the present invention. FIG. 2 is an external view schematically showing a state in which the floor-mounted air conditioner according to the embodiment of the present invention is installed indoors. FIG. 3 is a rear view schematically showing the configuration of the floor-mounted air conditioner according to the embodiment of the present invention.

  Referring mainly to FIG. 1, the floor-mounted air conditioner 1 of the present embodiment mainly includes a casing 10, a blower 41 and an indoor heat exchanger 40 arranged in the casing 10. Yes.

  1 to 3, casing 10 has a front surface and a back surface, a top surface, a bottom surface, and two side surfaces that face each other. The casing 10 includes a front panel 11, a back panel 12, a top panel 13, a bottom panel 14, and two side panels 15 at the front, back, top, bottom, and two side positions, respectively. Yes. The front panel 11 of the casing 10 is provided with an air outlet lower region 21A and an air outlet upper region 21B as the air outlet 21 that is an opening. The rear panel 12 of the casing 10 is provided with a suction port 20 that is an opening.

  The suction port 20 is located approximately in the middle between the blower outlet lower region 21A and the blower upper region 21B in the vertical direction.

  With reference to FIG. 1, the blower 41 is provided in the casing 10. The blower 41 enters the casing 10 through the suction port 20 and generates an airflow that exits the casing 10 through the blowout port 21. As the blower 41, for example, a sirocco fan or a turbo fan can be used.

  The indoor heat exchanger 40 is provided in the middle of the airflow path in the casing 10 and at a position upstream of the airflow with respect to the blower 41.

  Note that a lower damper 31A is provided at a position in the middle of the path of the airflow flowing between the blower outlet lower region 21A and the blower 41. Further, an upper damper 31B is provided at a position in the middle of the path of the airflow flowing between the blower outlet upper region 21B and the blower 41. Each of the lower damper 31A and the upper damper 31B has a function of suppressing or blocking airflow by being displaced as shown by the broken line in FIG.

Further, a guide 50 that restricts the path of the airflow is provided in the casing 10.
A support frame 51 for supporting the indoor heat exchanger 40 is provided in the casing 10.

The indoor heat exchanger 40 is connected to an outdoor unit (not shown).
Next, a method of installing the floor-mounted air conditioner 1 according to the present embodiment indoors for air conditioning will be described.

  2 and 3, floor-mounted air conditioner 1 is installed at a corner position formed by two wall surfaces 61 in the room. The orientation of the floor-mounted air conditioner 1 is such that the front panel 11 faces the main space in the room and the back panel 12 faces the corner. Thereby, a narrow space is formed between the back panel 12 and the two wall surfaces 61 in the room.

  The position where the floor-mounted air conditioner 1 is installed is not limited to the corner position as described above, and may be installed near one wall surface 61. In this case, the orientation of the floor-mounted air conditioner 1 is such that the front panel 11 faces the main space in the room and the back panel 12 faces one wall surface 61. Thereby, a narrow space is formed between the back panel 12 and the one wall surface 61 in the room.

Next, operation | movement of the floor-mounted air conditioner 1 of this Embodiment is demonstrated.
With reference to FIG. 1, an air flow is generated by operating the blower 41. First, this airflow enters the casing 10 through the suction port 20. Subsequently, this air flow is blown to the indoor heat exchanger 40. As a result, the temperature of the airflow increases during the heating operation and decreases during the cooling operation. Subsequently, the air current is divided into two air currents at the blower 41.

  One of the two airflows travels downward through a path limited by a guide 50 provided below the blower 41. And it blows off into the room | chamber interior from the lower part of the front panel 11 through 21 A of blower outlet areas. In addition, by operating the lower damper 31A as necessary, the blowing through the outlet lower region 21A is suppressed or blocked.

  The other of the two airflows travels upward through a path limited by a guide 50 provided above the blower 41. And it blows off into the room | chamber interior from the upper part of the front panel 11 through the blower outlet upper area | region 21B. In addition, by blowing the upper damper 31B as necessary, blowing through the outlet upper region 21B is suppressed or blocked.

Next, the effect of the integrated air conditioner of this Embodiment is demonstrated.
According to the floor-mounted air conditioner 1 of the present embodiment, the suction port 20 is provided in the back panel 12 of the casing 10 as shown in FIG. For this reason, it is not necessary to provide the opening part as the suction inlet 20 in the front panel 11. FIG. Therefore, since the opening of the front panel 11 only needs the blower outlet 21, an opening area can be made small. Therefore, the operation sound of the blower 41 leaking through the opening of the front panel 11 to the front surface of the floor-mounted air conditioner 1 can be reduced, and the indoor noise caused by the operation sound can be suppressed.

  Further, it is not necessary to provide an opening as the suction port 20 in the side panel 15. For this reason, the operation sound of the blower 41 leaking to the side surface of the floor-mounted air conditioner 1 through the opening of the side panel 15 can be reduced. Therefore, the indoor noise resulting from this driving | running sound can be suppressed.

  Further, it is not necessary to provide an opening as the suction port 20 in the top panel 13. For this reason, the operation sound of the blower 41 leaking to the upper surface of the floor-mounted air conditioner 1 through the opening of the upper panel 13 can be reduced. Therefore, the indoor noise resulting from this driving | running sound can be suppressed.

  For example, as shown in FIG. 2, the back panel 12 faces the wall surface 61. For this reason, the operation sound of the blower 41 leaking through the suction port 20 shown in FIG. 3 is directed to the wall surface 61 located in the vicinity facing the back panel 12. That is, this driving sound does not go toward the main space in the room. Therefore, it is possible to suppress indoor noise due to the operating sound of the blower 41 that leaks through the suction port 20.

  The indoor heat exchanger 40 is provided at a position upstream of the air flow with respect to the blower 41. For this reason, there is no indoor heat exchanger 40 between the blower 41 and the air outlet 21 that weakens the momentum of the airflow. Therefore, after the air discharged from the blower 41 is sufficiently rectified by the guide 50, it can be blown out vigorously from the outlet 21 into the room.

  Moreover, the indoor heat exchanger 40 which is a large component does not exist at a position downstream of the air flow with respect to the blower 41. For this reason, the freedom degree of design of the path | route of the airflow in the casing 10 between the air blower 41 and the blower outlet 21 is high. Therefore, the design freedom of the position where the blower outlet 21 is provided and the size of the blower outlet 21 is increased. Thereby, as shown in FIG. 1 and FIG. 2, not only the upper outlet region 21B but also the lower outlet region 21A can be provided below, so that the air can be urged from below into the room particularly during heating. By blowing out, it becomes possible to heat the room effectively.

  As shown in FIG. 2, a space is formed between the back panel 12 of the floor-mounted air conditioner 1 and the wall surface 61 in the room. For this reason, the suction port 20 provided in the back panel 12 is not blocked by the wall surface 61. Therefore, indoor air can be sucked from the suction port 20.

  As shown in FIG. 1, a lower damper 31 </ b> A is provided at a position in the middle of the path of the airflow that flows between the outlet lower region 21 </ b> A and the blower 41. An upper damper 31B is provided at a position in the middle of the path of the airflow flowing between the blower outlet upper region 21B and the blower 41. Thereby, the area | region where an airflow is blown out from the casing 10 can be selected.

  Thus, during the heating operation, for example, an operation for blowing the air flow from both the upper and lower portions of the casing 10 to warm the entire room, and an operation for blowing the air flow only from the lower portion of the casing 10 to intensively warm the vicinity of the indoor floor surface. And can be selected.

  Further, during the cooling operation, for example, the operation of cooling the entire room by blowing an air current from both the upper and lower portions of the casing 10 and the airflow being blown only from the upper portion of the casing 10 to excessively cool the vicinity of the indoor floor surface. The operation to be prevented can be selected.

  Moreover, as shown in FIG. 1, the suction inlet 20 is located in the approximate middle of the blower outlet lower area | region 21A and the blower outlet upper area | region 21B about an up-down direction. For this reason, air can be blown out in a well-balanced manner from both the outlet lower region 21A and the outlet upper region 21B.

  In addition, in this Embodiment, as shown in FIG. 2, although the case where the blower outlet 21 was located in the upper part and the lower part of the casing 10 was demonstrated, this invention is not limited to this. The blower outlet 21 may be located in the right part or the left part toward the front panel 11.

  Further, as shown in FIG. 4, the air outlet 21 may further include an air outlet side surface region 21 </ b> C disposed in the side panel 15.

  Further, the air outlet 21 may be located on the top panel 13. Alternatively, a chamfered shape may be provided between the front panel 11 and the side panel 15 or between the front panel 11 and the top panel 13, and the air outlet 21 may be located in this chamfered portion.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
