Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a scalable indoor unit of a separated type room air conditioner, which has a graphic decoration on the surface of the indoor unit, and expands the function by connecting a plurality of mounting seat units in response to a demand for air conditioning strength. And those that make it easier for producers to manage parts.

[0002]

[Prior art]

 During operation of a room air conditioner, the internal compressor generates extremely large vibrations and noises.Therefore, recently, the compressor and condenser have been installed as outdoor units, and the evaporator and its surroundings have been installed indoors. The mainstream is a separate room air conditioner, which is installed indoors to reduce the noise applied to the room, and the indoor units are mounted on the walls of the room to cool and heat the room.

The configuration of a well-known indoor unit is as shown in FIG. 6, in which an evaporator 2 is installed in a casing 1, a once-through fan 3 is provided at a lower end of the evaporator 2, and a shaft of the once-through fan 3 is provided. A fan motor 4 is connected to one end of the casing 1, a baffle plate 5 is provided below the once-through fan 3, and a plurality of air inlets 1 </ b> A are provided in a portion of the casing 1 corresponding to the front of the evaporator 2. An outlet 1B is provided at a portion corresponding to the wind plate 5, and when the fan motor 4 rotates, the once-through fan 3 rotates, and draws room air from the inlet 1A to the front of the evaporator 2 and converts the room air into room air. The heat is radiated on the evaporator 2 or the room air is heated to a high temperature by the evaporator 2 and then sent out from the outlet 1B to the room. Thus, the room air is convected and used for controlling the room temperature. Such a known indoor unit has the following disadvantages. 1. It employs a front air intake system and a system in which the wind passes through a flat evaporator and is blown by a once-through fan. The amount of refrigerant evaporated in the evaporator is combined with the size of the indoor unit. There are at least 6 to 8 types of indoor unit dimensional specifications corresponding to the size of the space to be used, and evaporators corresponding to each type are manufactured. Was. 2. When switching from the cooling function to the heating function, it is necessary to switch the flow direction of the refrigerant with the flow direction adjustment control valve provided in the outdoor unit, thereby causing the condenser and evaporator to perform the opposite operation. . However, due to the overall design, the outdoor unit is placed outdoors and is affected by the outdoor air temperature. If the outdoor temperature drops below 5 ° C, it will not operate properly, so it is necessary to perform step-type forced defrosting. This problem was particularly pronounced in cold regions. Therefore, in cold regions, such room air conditioners were often used merely for auxiliary heating. Furthermore, the technique of flowing the refrigerant in the opposite direction was complex, costly and impractical. 3. The exterior design of the indoor unit only considered the flexible and gentle modeling of the indoor unit itself, and did not consider the decorativeness.

[0004]

[Problems to be solved by the invention]

 It is an object of the present invention to provide a kind of scalable indoor unit of a separated type room air conditioner, in which an internal evaporator is manufactured according to an air regulation standard and a relatively small unit of standard parts is used. Comprehensive and housed in a hypothetical casing, the casing shall be mounted on a vertical surface and interconnectable to extend its air conditioning capacity. Specifically, for example, when the heat radiation capacity of one indoor unit of the present invention is designed to be 6000 to 15000 BTU, 15000 BTU is indoors by adjusting the wind speed by a single-row, two-row or three-row evaporator and a fan motor. It is possible to cope with the case where the range is less than the required range, that is, it has a sufficient air conditioning effect, and when the range of less than 30,000 BTU is required indoors, it is provided at the four corners of the mounting sheet 210 in the indoor unit unit of the present invention. The two mounting sheets are connected to each other by using one connecting plate by the fixing holes 212, and if only the face plate and the frame are doubled in the horizontal direction, it is possible to meet the requirement of 30,000 BTU or less. I do. In this way, appropriate combination can be made according to the size of the air conditioning area, and if external parts corresponding to various indoor unit standards are manufactured, internal mechanism parts can be handled with common parts. The main issue of the present invention is to make it possible to reduce the manufacturing cost, thereby reducing the number of parts and simplifying parts management.

[0005] The present invention also provides an electric heating element in the evaporator so that the air can be heated directly, eliminating the need to control the refrigerant to flow in the reverse direction and preventing the outdoor unit from operating during heating. The next task is to prevent the occurrence of frost formation on the machine, and to reduce the production and maintenance costs of air conditioners.

According to the present invention, the frame attached to the outside of the casing has decorativeness, and a pattern is drawn on a blind-type wind guide plate inside the frame. The task is to make the room air conditioner have an interior decoration effect so that the pattern appears when the boards are closed to each other.
