In the washing machine 1, the first tank 50a is housed in the first housing portion 60a, and the second tank 50b is housed in the second housing portion 60 b. The shapes of the second receiving portion 60b and the second tank 50b that are substantially line-symmetrical with respect to the first receiving portion 60a and the first tank 50a are main differences, and there is no great difference in the functions of the two. That is, the portions provided in the 1 st housing portion 60a and the 1 st tank 50a are also provided in the 2 nd housing portion 60b and the 2 nd tank 50b substantially similarly. Therefore, the 1 st housing portion 60a and the 1 st tank 50a will be described in detail below, and the 2 nd housing portion 60b and the 2 nd tank 50b will not be described in detail.
As described above, the detergent tank 50 is mounted on the housing bottom surface 61 of the tank housing 60 and is attached to the main body case 10. A tank discharge portion 51e (see fig. 7 described later) for discharging the detergent contained therein is provided on the bottom surface of the detergent tank 50, and is connected to a main body inlet 62 provided in the tank storage portion 60. Although not shown in fig. 4, check valves are provided in the main body inlet 62 and the tank discharge portion 51e, and the detergent supplied from the detergent tank 50 to the detergent input portion 32 is not allowed to flow backward. The main body inlet 62 is configured to press the tank discharge portion 51e by applying pressure with a sealing member such as rubber, so as to prevent the connected tank discharge portion 51e from falling off by an unexpected force or a gap from being generated and the detergent from leaking.
The storage bottom surface 61 has a shape corresponding to the bottom surface of the detergent tank 50, and is substantially rectangular in a plan view in the present embodiment. The shorter side direction of the storage bottom surface 61 is along a direction (vertical direction in fig. 4) in which the front and rear portions of the washing machine 1 face each other, and the longer side direction of the storage bottom surface 61 is along a direction (horizontal direction in fig. 4) in which the left and right side surfaces of the washing machine 1 face each other. The first receiving portion 60a and the second receiving portion 60b are arranged in parallel in the longitudinal direction of the two portions.
A handle housing portion 63 is provided at a position higher than the housing bottom surface 61 in a part of the outer periphery of the tank housing portion 60. The handle housing 63 is formed in a shape corresponding to the handle 54, and houses the handle 54 attached to the detergent tank 50 (see fig. 6 described later). A side wall is erected along the outer periphery of the housing bottom surface 61, and the handle housing 63 is provided so as to surround a part of the outer side of the side wall.
In fig. 5, the upper portions of the side walls opposed in the longitudinal direction in the tank housing portion 60 are shown enlarged, and the end portion of the handle housing portion 63 is located in the vicinity thereof. An accommodation lower surface portion 63a (which is a part of the pressing portion and corresponds to the first contact surface) facing the lower surface of the accommodated handle 54 and an accommodation protrusion portion 63b (which is a part of the pressing portion and corresponds to the second contact surface) protruding so as to cover a part of the accommodation lower surface portion 63a are provided at an end portion of the handle accommodation portion 63. A gap is provided between the housing lower surface portion 63a and the housing protrusion portion 63b, and a part of the handle 54 (the attachment/detachment assisting portion 54c shown in fig. 8) is housed in the gap. The positional relationship between the handle 54 and the handle accommodating portion 63 will be described with reference to fig. 10 and 11 described later.
Fig. 6 is a plan view showing the detergent box, fig. 7 is a bottom view showing the detergent box, and fig. 8 is a side view showing the detergent box. Fig. 6 to 8 show a first tank 50a as one of the detergent tanks 50.
The detergent tank 50 is composed of a tank main body 51, a tank cover 52, a handle 54, and a small window cover 53.
The tank main body 51 is a substantially rectangular parallelepiped container having an upper surface opened as a whole, and is substantially rectangular in a plan view, and has rounded corners. A tank discharge portion 51e is provided near an end portion in the longitudinal direction on the bottom surface of the tank main body 51, and the tank discharge portion 51e is provided at a position overlapping with the main body introduction port 62.
The can lid 52 is formed in a shape corresponding to the can body 51, and is attached to the can body 51 to cover the upper surface of the can body 51. The can lid 52 and the can body 51 sandwich the gasket therebetween to close the gap. The gasket is not particularly limited, and may be attached so as to cover the outer periphery of the can cover 52, or may be attached along the upper end of the can body 51.
A small window is provided in a part of the can cover 52, and the small window cover 53 covers the small window from above. The small window cover 53 is configured to be openable, closable, and detachable with respect to the tank cover 52, and a user can replenish the detergent by opening (or detaching) the small window cover 53.
The handle 54 has: a handle extension portion 54a which extends a grip 54b from a portion to be locked to the handle shaft 51a, and an end portion of which is connected to the handle extension portion 54a and is gripped by a user; and a detachable auxiliary portion 54c extending from a portion locked with the handle shaft 51a to a side opposite to the handle extension portion 54 a. That is, the handle 54 is formed in a flat bar shape with both ends bent, and both ends are pivotally supported by the handle shaft 51 a. In the handle 54, a portion pivotally supported by the handle shaft 51a is not the most distal end but is slightly displaced inward, and a portion extending from the portion pivotally supported to the distal end serves as a mounting/demounting assistance portion 54 c.
In fig. 8, the grip 54b is moved to the side of the detergent tank 50, and in this state, the downward facing portion of the attachment/detachment assisting portion 54c is the lower surface contact portion 54d, and the upward facing portion is the upper surface contact portion 54 e. The lower surface contact portion 54d is formed of a curved surface extending to the distal end of the attachment/detachment assisting portion 54c, and the distance from the handle shaft 51a increases as the distal end of the attachment/detachment assisting portion 54c approaches. The lower surface contact portion 54d is not limited to this, and may be formed as a rounded curved surface at each portion of the handle 54.
Fig. 9 is an enlarged plan view showing a tank storage portion in which the detergent tank is stored.
As shown in fig. 9, when the handle 54 is accommodated in the handle accommodating portion 63, the attachment/detachment assisting portion 54c is accommodated between the accommodating lower surface portion 63a and the accommodating projecting portion 63 b. Hereinafter, for the sake of explanation, the state in which the handle 54b is moved to the side of the detergent tank 50 and the handle 54 is accommodated in the handle accommodating portion 63 may be referred to as an accommodated state. On the other hand, the state in which the handle 54b is moved upward of the detergent tank 50 and the handle 54 is taken out from the handle housing 63 may be referred to as a take-out state.
Next, the movement of the handle 54 when the detergent tank 50 is attached to and detached from the tank storage portion 60 will be described with reference to fig. 10 and 11.
Fig. 10 is a schematic side view showing the tank storage part and the detergent tank in a storage state, and fig. 11 is a schematic side view showing the tank storage part and the detergent tank in a removal state. In fig. 10 and 11, a part of the side wall of the tank housing portion 60 is shown in a perspective view in view of the ease of drawing.
As shown in fig. 10, in the accommodated state, the upper surface contact portion 54e faces the accommodating projection portion 63b, and the lower surface contact portion 54d faces the accommodating lower surface portion 63 a. Then, the tank discharge portion 51e is press-fitted into the main body introduction port 62. As shown in fig. 11, in the removed state, the front end of the attachment/detachment assisting portion 54c abuts against the housing lower surface portion 63 a. The bottom surface of the tank main body 51 is separated from the housing bottom surface 61, and the tank discharge portion 51e is not pushed into the main body introduction port 62.
When the detergent tank 50 is stored in the tank storage portion 60, the user holds the grip 54b to hang the detergent tank 50, and the grip 54b is positioned above the detergent tank 50 in the removed state. When the detergent tank 50 is inserted into the tank housing portion 60 from above, as shown in fig. 11, the distal end of the attachment/detachment assisting portion 54c abuts the housing lower surface portion 63a before the bottom surface of the tank main body 51 contacts the housing bottom surface 61. From this state, the handle 54 is rotated about the handle shaft 51a as a fulcrum, and the grip 54b is moved in the storage direction D1 from above the detergent tank 50 to the side and stored in the handle storage portion 63. At this time, the force for rotating the handle 54 is transmitted to the detergent tank 50 as a force (arrow F1) for pressing itself downward via the vicinity of the upper surface contact portion 54e in contact with the housing protrusion portion 63b, and the tank discharge portion 51e is pushed into the main body inlet 62. That is, the upper surface contact portion 54e of the attachment/detachment assisting portion 54c pushes the accommodating protrusion 63b (pressing portion) upward, so that the attachment/detachment assisting portion 54c is pushed back downward, and the detergent tank 50 is accommodated in the tank accommodating portion 60. Thus, the removal state is switched to the storage state.
Since the detergent tank 50 is stored when it is taken out from the tank storage portion 60, the grip 54b is located on the side of the detergent tank 50. From this state, the handle 54 is rotated about the handle shaft 51a as a fulcrum, and the grip 54b is moved in the removal direction D2 upward from the side of the detergent tank 50 and removed from the handle accommodating portion 63. As a result, in the handle 54, the portion that abuts against the housing lower surface portion 63a (pressing portion) and presses the housing lower surface portion 63a is shifted from the lower surface abutting portion 54d toward the tip of the attachment/detachment assisting portion 54c, and the handle shaft 51a is separated from the housing lower surface portion 63a accordingly. That is, the force (arrow F2) pushing up the detergent tank 50 is transmitted.
In this way, by using the principle that the movable handle 54 is rotated instead of simply pulling up the detergent tank 50 with the handle 54, it is possible to assist the user in attaching and detaching the detergent tank 50 with a light force. Further, by providing the attachment/detachment assisting portion 54c with a curved surface, the handle 54 can be smoothly rotated along the curved surface, and the attachment/detachment of the detergent tank 50 can be further assisted.
The length from the handle shaft 51a to the handle extension 54a is preferably longer than the length from the handle shaft 51a to the attachment/detachment assisting section 54 c. Accordingly, the force applied from the grip 54b to the end of the handle extension portion 54a is multiplied by this principle and acts on the attachment/detachment assisting portion 54 c. Therefore, the attachment/detachment of the detergent tank 50 can be reliably assisted with a smaller force.
As described above, when the detergent tank 50 is stored in the tank storage portion 60, the grip 54b is configured to move to the side of the detergent tank 50. At this time, the attachment/detachment assisting portion 54c extends toward the side surface opposite to the grip 54 b. In the detergent tank 50, a force for rotating the handle 54b is applied to one side surface side, and a force generated by the attachment/detachment auxiliary portion 54c is applied to the opposite side surface side. By combining the two forces, the entire detergent tank 50 is pressed downward, and the inclination of the detergent tank 50 can be suppressed, thereby improving stability.
(second embodiment)
Next, a washing machine according to a second embodiment of the present invention will be described with reference to the drawings. In the second embodiment, the structure of the detergent tank 50 and the tank housing 60 is different from that of the first embodiment, and the structure is substantially the same as that of the first embodiment, so that the different portions will be described in detail, and the description of the other portions will be omitted.
Fig. 12 is a schematic side view showing the tank storage unit and the detergent tank in a stored state in the second embodiment of the present invention, and fig. 13 is a schematic side view showing the tank storage unit and the detergent tank in a removed state in the second embodiment of the present invention.
In the second embodiment, a mounting/dismounting assistance mechanism for assisting the mounting/dismounting of the detergent tank 50 to/from the tank housing portion 60 is provided. The attachment/detachment assisting mechanism includes a tank receiving portion 73b provided in the detergent tank 50 and a main body driving portion 73a provided in the tank housing portion 60. Specifically, the tank receiving portion 73b is a protrusion, and the main body driving portion 73a is a lever that rotates about an axis as a fulcrum. The tank receiving portion 73b is provided at a position abutting against the main body driving portion 73a when the detergent tank 50 is accommodated in the tank accommodating portion 60. The main body driving portion 73a presses or pushes up the canister receiving portion 73b by rotating. Thus, the main body driving unit 73a applies a force to the tank receiving unit 73b to move the detergent tank 50 with respect to the tank receiving unit 60. The detergent tank 50 is switched between the storage state and the removal state by the movement of the main body driving unit 73 a. Thus, the detergent tank 50 can be easily removed with the aid of the attachment/detachment assisting mechanism.
The attachment/detachment assisting mechanism is not limited to the above configuration, and may be, for example, a rack gear in which the tank receiving portion 73b is a rack gear and a gear in which the main body driving portion 73a is a pinion gear.
In the second embodiment, a sensor for detecting the position of the detergent tank 50 with respect to the tank housing portion 60 is provided. Specifically, the storage bottom surface 61 is provided with a microswitch 71, and the microswitch 71 detects whether or not the bottom surface of the tank main body 51 is in contact with the storage bottom surface 61. A reed switch (mark detection sensor 72a) that detects whether or not a magnet (can mark 72b) provided in the can main body 51 is in proximity is provided on the side wall of the can housing portion 60. The positional relationship between the can mark 72b and the mark detection sensor 72a may be appropriately adjusted, and for example, the mark detection sensor 72a may detect the can mark 72b when the can discharge portion 51e is pulled out from the main body introduction port 62. The can mark 72b is not limited to this, and may be any mark detection sensor 72a as long as it can be detected by the mark detection sensor 72a, and the mark detection sensor 72a may be an optical sensor such as an uneven portion or a colored portion provided on a side surface of the can body 51.
The attachment/detachment support mechanism may be provided with a button or the like and operated in response to a user's instruction, or may be operated in response to the position of the detergent tank 50 detected by a sensor.
