Description

[Detailed description of the invention] (a) Industrial application field This invention relates to an air conditioner to which a heater for space heating can be attached as appropriate.

(b) Conventional technology In order to compensate for the lack of heating capacity, heat pump type air conditioners for extremely cold regions are equipped with a heater for heating, but conventional air conditioners are
As disclosed in Publication No. 57-53299, the cosmetic case had to be removed during service inspection of this heater, making the work complicated.

(c) Purpose The purpose of this proposal is to provide an air conditioner in which the service inspection of the heating device can be easily performed and the heating device, which is available as a separately sold part, can be easily incorporated in accordance with the customer's request. It is in.

(d) Configuration In this case, a heater for heating is housed in the ventilation path of the main body, which has a built-in heat exchanger and fan, through an opening in the top plate of the main body.

(E) Example To explain based on the drawings, 1 is a casing in which a top plate 2, a back plate 3, and a bottom plate 4 are integrally formed of sheet metal, and 5 is a casing that extends from the top plate 2 to the upper half of the back plate 3. Pasted glass wool insulation material, 6 is back plate 3
A fan casing made of foamed urethane is attached from the lower half of the unit to span the bottom plate 4, 7 is a decorative panel fixed to the bottom plate 4 with screws 8, and 9 is a suction panel. An outer box is formed.

11 is a heat exchanger disposed behind the suction panel 9 and acts as an evaporator during cooling and as a condenser during heating; 12 is a drain pan with a heat insulating material 13 disposed below the heat exchanger; 14 is a heat exchanger disposed behind the suction panel 9; Crossflow fan, 15 is an auto louver that automatically diverts the discharged air to the left and right, 16 is a flap that changes the discharged air to the front or diagonally downward direction, 1
7, a heat insulating material 18a and a sealing material 18b are pasted,
An air filter 19 inserted along the suction panel 9 is fixed to the indoor wall surface 20 and the main body 10
This is a wall hanging board to which a hook 21 is attached.

22 is an opening made in the top plate 2 of the main body 10. When the heating capacity of the heat exchanger 11 alone is sufficient, the opening 22 is closed with a blind plate 23 as shown in FIG. If the heating capacity of 11 is insufficient, remove the blind plate 23 and open the opening 22 as shown in Figure 2.
The lid 2 has the sheathed heater 24 fixed between a pair of support plates 25 by cutting the insulation material 5 with a knife along the
A heater 27 with a heater 6 is housed in a ventilation passage 28 of the main body 10 through the opening 22. 29 is a heat insulating material attached to the outside or inside of the lid 26; 30 is a heat insulating material led out from the lid 26 and connected to the main body 10;
This is a lead wire connected to the electrical equipment control box (not shown).

With the above structure, when the heating device 27 is to be serviced or newly installed in response to a customer's request, the main body 10 is attached to the wall-mounted plate 20.
It is only necessary to remove the heat exchanger 11 from the top plate 2 and store it from the top plate 2, and it is possible to easily work on the equipment such as the heat exchanger 11 without removing it from the outer box of the main body 10.

In addition, the heating heater 27 is simply inserted and suspended by the lid 26 that is in close contact with the top plate 2, so it can be easily fixed with the screws 31, and the heating heater 27 suspended and stored in the ventilation passage 28 exchanges heat. Vessel 11
The hot air from the can be reheated.

(f) Effects According to this proposal, there is no need to remove the cosmetic case when installing and storing the heating device, so service inspection work and on-site installation work can be easily performed. Since the air conditioner is stored and suspended through the opening of the air conditioner, it can be easily and firmly installed.In addition, if the air conditioner is a wall-mounted type that can be installed high on an indoor wall, the top plate will not be visible, so the aesthetic appearance will not be affected. .
