A rectangular parallelepiped water tank 6 is inserted into the water tank insertion portion 18 while sliding. The water tank insertion portion 18 may be formed in a downward opening box shape that covers all four side surfaces of the water tank 6, but in the example of FIG. 2, power is supplied to the heater unit 14 among the four side surfaces of the water tank 6. The portion corresponding to the side surface having the take-out portion 19 of the electric wire 15 for opening is opened so that the wire take-out portion 19 does not get in the way when the water tank 6 is inserted into and removed from the water tank insertion portion 18. As the simplest form of the water tank insertion portion 18, it is possible to adopt a configuration using four angle members that guide the intersections of the four side surfaces of the water tank 6.

As shown in FIG. 2, the water tank 6 is provided with a stopper 20. The stopper 20 is formed to protrude from the side surface of the water tank 6. Corresponding to the stopper 20, as shown in FIG. 3, a latch 21 is provided in the water tank insertion portion 18. By engaging the stopper 20 and the latch 21, the water tank 6 is supported by the water tank insertion portion 18, and by disengaging the stopper 20 and the latch 21, the water tank 6 can be removed from the water tank insertion portion 18. . The stopper 20 is usually provided on each of the opposite sides of the water tank 6 as in the example of FIG. 2, but when the clearance between the water tank insertion portion 18 and the water tank 6 is small, the stopper 20 is provided. The number of arrangement of 20 can be made one. The number of latches 21 provided is the same as the number of stoppers 20 provided.

The stopper 20 is preferably disposed below the water tank 6, and the latch 21 is preferably disposed below the water tank insertion portion 18 correspondingly. This is because by disposing the stopper 20 and the latch 21 at a low position, the engagement release operation of the stopper 20 and the latch 21 on the back of the ceiling can be easily performed from the room 7 side as much as possible.

As shown in FIGS. 3 and 4, a stopper receiving groove 22 is formed in the lower portion of the water tank insertion portion 18. The stopper receiving groove 22 extends in the vertical direction. When the water tank 6 is inserted into the water tank insertion portion 18 from the bottom to the top, the stopper 20 provided on the side surface of the water tank 6 moves upward in the stopper receiving groove 22.

A sleeve 23 extending in the horizontal direction is provided on the outer surface of the lower portion of the water tank insertion portion 18, and a slider 24 is slidably fitted in the sleeve 23. The slider 24 integrally includes a latch 21, a catcher 25, and an operation unit 26. The slider 24 includes a non-operation position (position of FIG. 4A) in which the operation portion 26 at the end protrudes from the sleeve 23 in the horizontal direction and an operation position in which the operation portion 26 is fully pushed into the sleeve 23 from the non-operation position [ Between the position of FIG. 6A] and is always urged by the spring 27 toward the non-operation position.

As shown in FIG. 4, the spring 27 is installed between the fixed side spring hanging piece 28 and the moving side spring hanging piece 29. The fixed side spring hanging piece 28 is formed to protrude from the outer surface of the water tank insertion portion 18, and the moving side spring hanging piece 29 is formed to protrude from the side surface of the slider 24. A slit 30 extending in the moving direction of the slider 24 is formed in the slider 24, and one end 30a of the slit 30 abuts against the fixed-side spring hooking piece 28, whereby the slider 24 is held at the non-operation position [FIG. )], The other end 30b of the slit 30 abuts against the fixed-side spring hooking piece 28, whereby the slider 24 is held at the operating position [FIG. 4 (c)].

The latch 21 can move between a lock position corresponding to the non-operating position of the slider 24 [position shown in FIG. 4A] and a release position corresponding to the operating position of the slider [position shown in FIG. 6A]. It is. The lock position is a position where the latch 21 protrudes into the stopper receiving groove 22, and the release position is a position where the latch 21 is released from the stopper receiving groove 22 in the lateral direction. The latch 21 is constantly biased toward the lock position by the spring 27. The latch 21 includes a guide surface 21a that extends obliquely from the bottom to the top, and a horizontal lock surface 21b that is continuous with the guide surface 21a and located above the guide surface 21a. The guide surface 21a is a surface with which the stopper 20 slides when the stopper 20 moves in the stopper receiving groove 22 from the bottom to the top. The lock surface 21b is a surface on which the stopper 20 is placed and supported.

The catcher 25 moves between a retracted position corresponding to the non-operating position of the slider 24 [position of FIG. 4A] and a receiving position corresponding to the operating position of the slider 24 [position of FIG. 6A]. Is possible. The receiving position is a position where the catcher 25 has advanced into the stopper receiving groove 22, and the retracted position is a position where the catcher 25 is laterally removed from the stopper receiving groove 22. The catcher 25 is always urged toward the retracted position by the spring 27. The catcher 25 is disposed below the latch 21. The catcher 25 moves into the stopper receiving groove 22 in place of the slider 21 that moves laterally away from the stopper receiving groove 22 when the slider 24 is moved to the operating position and the engagement between the stopper 20 and the latch 21 is released. And advance. Thereby, the stopper 20 falling from the latch 21 is temporarily received and the water tank 6 is temporarily held.

A bent portion 25a is formed at the tip of the catcher 25 as an upward protruding portion. The bent portion 25a prevents the stopper 20 from being detached from the catcher 25 that attempts to return to the retracted position by the action of the spring 27.

The operation unit 26 is a part for operating the slider 24 from the non-operation position to the operation position. When the slider 24 is in the non-operation position, the latch 21 is in the lock position and the catcher 25 is in the retracted position. When the operation unit 26 is pushed to move the slider 24 to the non-operation position, the latch 21 moves to the release position and the catcher 25 moves to the receiving position. When the operation unit 26 is released, the slider 24 is automatically returned to the non-operation position by the spring 27.

With reference to FIG. 5, the attachment process of the water tank 6 with respect to the main-body part 5 is demonstrated.

FIG. 5A shows the positions of the latch 21 and the catcher when the slider 24 is in the non-operation position. At this time, the latch 21 is in the locked position and the catcher 25 is in the retracted position. When an operator inserts the water tank 6 into the water tank insertion part 18 of the main body part 5 from the bottom to the top, the stopper 20 provided on the side surface of the water tank 6 is a stopper receiving groove provided in the water tank insertion part 18 in the final stage of the water tank insertion Enter 22.

When the worker pushes the water tank 6 further upward, the guide surface 21a of the latch 21 is pushed by the stopper 20 that moves upward in the stopper receiving groove 22 as shown in FIGS. The latch 21 is pushed away from the lock position toward the release position. When the stopper 20 passes through the latch 21 upward, the latch 21 is automatically returned to the locked position by the spring 27 as shown in FIG. Thereby, since the lock surface 21b of the latch 21 enters under the stopper 20, even if an operator releases a hand from the water tank 6, the water tank 6 does not fall. This state is an attached state of the water tank 6 to the main body 5. Thereafter, the worker connects the electric wire 15 of the heater unit 14 to the control unit 9.

Next, with reference to FIG. 6, the removal process of the water tank 6 from the main-body part 5 is demonstrated.

Prior to removing the water tank 6, first, the electric wire 15 of the heater unit 14 is removed from the control unit 9. Next, when the operator pushes the operating portion 26 of the slider 24 fully from the attached state of FIG. 5D, the slider 24 moves to the operating position as shown in FIG. 21 moves to the release position and the catcher 25 moves to the receiving position. Since the engagement between the stopper 20 and the latch 21 is released by the movement of the latch 21 to the release position, the water tank 6 falls due to its own weight, and the stopper 20 moves downward in the stopper receiving groove 22. This stopper 20 is received by the catcher 25 in the receiving position, and further dropping of the water tank 6 is restricted.

When the worker releases his / her hand from the operation unit 26, the slider 24 tries to return to the non-operation position by the action of the spring 27. However, since the bent portion 25a for preventing detachment is formed at the tip of the catcher 25, the stopper 20 does not come off from the catcher 25 [see FIG. 6 (b)].

When the worker pushes up the water tank 6 slightly from the state of FIG. 6B, the bent portion 25a of the catcher 25 is detached from the stopper 20, and as shown in FIG. Automatically returns to the non-operating position. As a result, the catcher 25 retreats to the retracted position, so that there is no restriction on the downward movement of the stopper 20, and the operator can remove the water tank 6 from the water tank insertion portion 18.

As described above, according to the present embodiment, by simply inserting the water tank 6 from the bottom to the top with respect to the water tank insertion portion 18, the attachment of the water tank 6 to the main body portion 5 is completed. The removal of the water tank 6 from the main body 5 is completed simply by performing the pressing operation and pushing up the water tank 6. Therefore, attachment and removal of the water tank 6 with respect to the main-body part 5 can be performed easily and rapidly.
