Abstract

PURPOSE:To obtain a thin and compact air conditioner suitable both for housing in a pendant wall and for embedding in a wall by a method wherein a pair of heat exchanger and blower and a wind direction changing damper are used, and an air suction inlet is provided on the upward side and an air blow outlet on the downward side. CONSTITUTION:An air blow outlet 7 is positioned downward of a blower, and a wind direction changing damper 8 is provided just below the outlet 7 to be rotated around a shaft 10 by a stepping motor 9. An air suction inlet 11 is positioned upward of a heat exchanger. Blow-out grilles 12a and 12b are provided rotatably around shafts 13a and 13b on the right and left hands of the air blow outlet 7. An interior unit 14 consisting of these components is set and fixed inside of a wooden frame 16 which is inserted into a pendant wall 15, and mounted on both sides with smoothly planed grilles 17a and 17b by means of screws 18. Air suction grilles 19a and 19b are provided in the upper parts of the grilles 17a and 17b. A front panel 20a on one side is mounted so as to open forward for permitting placing and displacing of an air filter.

Description

[Detailed Description of the Invention] Industrial Application Field The present invention is a double-blow air conditioner that can cool and heat two rooms with one unit, and the same unit can also be used as a wall embedded in one room. The present invention relates to a dual-use air conditioner that can be used as a double blower or as a wall-mounted air conditioner.

Conventional technology Some conventional double-blow air conditioners have been put into practical use, with only a floor-standing unit placed on the floor of a storage shelf that spans two rooms so that only the air outlet can blow air in both directions. (for example, Utility Model Application No. 52-56450)
Currently, there are no thin double-blow air conditioners that can be placed in the hanging walls or walls of two rooms. Furthermore, at present, there are no air conditioners that can be used to blow both sides of the air in one unit.

Problems to be solved by the invention: Due to the large depth and size of conventional air conditioners, they cannot be installed within a hanging wall that spans two rooms; In addition, conventional methods require double-blow-only air conditioning when commercializing the product.
Alternatively, it may be used only for wall filling, and the cost may be high due to the need for molding costs for each. Component joint plate A pair of heat exchangers, a blower, and a wind direction changing damper are used.1. X, Unique structure with a suction port on the upper side and a blower port on the lower side, also works.The above structure makes the present invention thin and compact and can be stored in a hanging wall, and can also be used as a wall embedding. It can be provided at a low cost, and can be matched with interior decoration.

Embodiment FIG. 1 shows an embodiment of the double blower and wall-mounted air conditioner of the present invention. In the figure, 1 indicates a heat exchanger 2, and a cross-flow type air blower; 5 is a water tray, which is made thinner than the others, so the heat exchanger has a curved central part, and 6 is an air filter, which is installed on the front windward side of the heat exchanger and covers almost the entire surface of the heat exchanger to prevent dust. The arrangement is such that the ventilation resistance during adhesion is reduced. 7 is an air outlet and is installed below the blower. A wind direction changing damper 8 is installed immediately below the air outlet. The suction port 11 is provided above the heat exchanger.Furthermore, on the left and right sides of the air outlet, outlet grilles 12a and 12b are connected to the shaft 13a.
, 13b. The indoor unit L4i; L consisting of these components is installed and fixed inside the wooden frame I6 fitted into the hanging wall 15, and decorative grilles 17a and 17b are installed on both sides of it. Even though it is attached with screws 18, there is an intake grill 19a above this decorative grill.
19b is provided, and one front panel 20a is attached to the front so that it can be opened and closed forward for attaching and detaching the air filter.The other front panel 20b is fixed to the center of the decorative grille. Furthermore, on the back of the fan casing 4, there is a drain hose 21, and indoor/outdoor connection piping 2'2. Although a recess 24 is provided to accommodate the connecting wire 23, the side-blown and wall-embedded air conditioner of the present invention may be installed on a hanging wall 15 spanning two rooms A and B as shown in FIG. The indoor unit) 14 is connected to the outdoor unit through the indoor/outdoor connection piping 22, and remote controllers 26, 26' for operating the indoor unit are connected to rooms A and B. As shown in Fig. 4, in addition to the operation stop button, the wind direction change damper operation button 27, 28 and the room temperature detection sensor 29 are provided. To explain using Figures 3 and 4, first press the operation button on the remote control, and if you want to operate both chambers A and B at the same time, press the wind direction change damper operation buttons 27 and 28, and the damper will be positioned in the center as shown in (a). (The air conditioning will evenly air the rooms and the wind will be distributed almost evenly.) If only room A is air-conditioned, press the operation button 27 and the damper will move as shown in (b) to air-condition only room A. When only room B is air-conditioned, pressing the operation button 28 moves the damper as shown in (C), and air-conditions only room B. Also, if the room temperature in room A reaches the set temperature using the room temperature detection sensor, the damper will (b) move to blow more air in the direction of the room.
When the room temperature reaches the set value in both compartments, the compressor (not shown) is activated.
The device is controlled to reduce or stop the operating speed of the motor.Next, it can also be used as a wall-filling device, as shown in Figure 5.In this case, a flat plate 31 is attached to the wall 30. Embed the wooden frame 16 into the wall in advance.In contrast, install and secure the indoor unit inside from the front.
A decorative grille I7 is attached to the front of the grille, and a sealing material 32 made of foamed polyethylene or the like is inserted into one side of the outlet grille 12b to prevent air leakage.
Further, a piping cover 34 is detachably attached to the rear side of the suction grill 19 so that it can be used as a piping connection space 33. When used exclusively for wall-embedding, the wind direction changing damper 8 may be fixed at the position shown in the figure (Fig. 5), but the sealing material 32 may not be used and the air leakage prevention gasket 35 may be used. In order to make it as thin and compact as possible, the present invention uses a minimum number of parts, namely a pair of heat exchangers, a blower, and one wind direction changing damper L'1. The unique structure with the air outlet located below the main 1° suction port has made it possible to create a thin and compact indoor unit that can be installed inside a hanging wall.In addition, the same indoor unit Since the same mold can be used, it is possible to construct a decorative grille that can be provided at a low cost and has an excellent interior design, and has great effects such as being able to freely and comfortably air-condition two rooms with one unit. It is something.
