Abstract

(57) [Abstract] [Purpose] Reduce the number of parts in the air conditioner indoor unit,
Makes assembly easier. [Structure] Inside the indoor unit, there is a heat exchanger 9 divided into a plurality as shown in FIG. If the split surface of this heat exchanger 9 is left open, air that is not heat-exchanged will pass, the heat exchange rate will decrease, and the dew condensation water flowing down from the upper heat exchanger 9 during dehumidification operation, etc. It may be scattered without being transmitted to the heat exchanger 9. In order to solve these problems, it is necessary to insert the shield 13 on the divided surface. Conventionally, the shield 13 was separately formed, but in order to reduce the number of parts, the front panel 3 and the shield 13 are integrally formed of resin.

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an indoor unit of an air conditioner, and more particularly, to improve the heat exchange rate of at least two divided heat exchangers arranged in the air passage of the indoor unit, and to improve the heat exchange of the upper part. The present invention relates to means for preventing scattering of condensed water flowing down from a container.

[0002]

[Prior art]

 The housing of the indoor unit of the air conditioner is, for example, a main body 2 as shown in FIG. 1, a front panel 3 detachably attached to the main body 2, and a front upper portion of the front panel 3 that can be opened and closed. It is composed of a suction grill 4 which is axially supported, and suction ports 5a and 5b for taking in the indoor air are provided in the upper part of the casing 1, and the heat-exchanged air is taken into the room in the lower front part. An outlet 6 is formed for delivery. The inside of the housing 1 is configured as shown in FIG. 2, and the inside of the air passage 7 connecting the suction ports 5a and 5b and the air outlet 6 is arranged along the filter guide 3a formed integrally with the front panel 3. There are an air filter 8 that can be attached and detached, a heat exchanger 9 that is vertically divided into three parts and the upper two parts are inclined rearward of the air passage 7 in an inverted V shape, and a blower (cross flow fan) 10 and the like. The air whose heat has been exchanged by the heat exchanger 9 is blown out indoors by the blower 10.

[0003]

[Problems to be solved by the device]

 By the way, if the heat exchanger 9 is divided as described above, the air passing through the divided surface is not heat-exchanged, so that the heat exchange rate is lowered. Further, during cooling operation, the fin surface of the heat exchanger 9 may cause dew condensation due to a temperature difference between the fin and the indoor air taken in through the suction ports 5a and 5b in the upper part of the housing. Since it lowers, a predetermined dehumidifying operation is executed, but in the case of an indoor unit that has been used for a long time (long years), the air filter 8 removes the fin end surface of the heat exchanger 9 on the windward side. Since a large amount of dust that could not be removed adheres to the fins and the gap between the fins is narrowed, the dew condensation water (water droplets) that flows down the fin end faces cannot fully penetrate between the fins during dehumidifying operation. It flows down the inclined surface of, and at the end it jumps out to the front side of the air filter 8 to wet the air filter 8 and the inside of the machine, causing mold. Therefore, in the conventional indoor unit, a resin-made shield 14 as shown in FIG. 4 is attached to the front division surface of the heat exchanger 9 which is divided into two or three, to eliminate unnecessary air flow. In addition to preventing this, the dew condensation water flowing down from the upper heat exchanger is received and allowed to flow backward to prevent scattering of the dew condensation water. It was also disadvantageous in terms of cost. Therefore, it is an object of the present invention to provide an indoor unit of an air conditioner that can solve the above problems with a simpler configuration.

[0004]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problems, and includes an air filter that can be detachably attached to an air passage that connects a suction port at the upper part of the housing and an air outlet at the lower part of the housing, and at least vertically. An indoor unit of an air conditioner comprising a heat exchanger divided into two parts, the upper part of which is inclined toward the rear of the air passage, and a blower or the like for sending the heat-exchanged air to the air outlet. On the back surface of the filter guide that guides the heat exchanger, a shield that shields the forward dividing surface of the heat exchanger and receives the condensed water flowing down from the upper heat exchanger is integrally provided.

[0005]

[Action]

 With the above configuration, since the shield formed integrally on the back surface of the filter guide can shield the front dividing surface of the heat exchanger, it is possible to prevent unnecessary air flow that is not heat-exchanged. The condensed water flowing down from the inclined surface of the upper heat exchanger can be received by the lower heat exchanger.

[0006]

【Example】

 Hereinafter, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows the appearance of an indoor unit. The housing 1 includes a main body 2, a front panel 3 which is detachably attached to the main body 2, and a front panel whose front end is located in front of the front panel 3 and has an upper end. 3 and a suction grill 4 which is rotatably supported at the upper part. Suction ports 5a and 5b for indoor air are provided in the upper part of the housing 1, and an air outlet 6 is formed in the lower part of the front surface. FIG. 2 is a side sectional view showing the inside of the indoor unit. An air passage 7 is formed between the suction ports 5a, 5b and the air outlet 6, and the air passage 7 is formed integrally with the front panel 3. A removable air filter 8 that can be moved to the main body 2 side along the front surface of the filtered filter guide 3a, and a heat that is divided into three parts and the upper two parts are bent to the rear of the air passage 7 in an inverted V shape. An exchanger 9 and a blower (cross flow fan) 10 are arranged, and the air that has undergone heat exchange by the heat exchanger 9 is sent to the outlet 6 by the blower 10, and the air direction into the room is adjusted by the wind direction plates 11 and 12. It is supposed to be done.

By the way, if the split surface of the heat exchanger 9 is left open as shown in FIG. 2, air that is not heat-exchanged flows to the blower 10 side, or the heat exchanger in the upper front part. There arises a problem that the condensed water flowing down from 9 is scattered on the air filter 8 side. Therefore, it is necessary to provide a shield on the front division surface of the heat exchanger 9 as a means for preventing such useless air flow and dew condensation water scattering. The configuration will be described below with reference to FIG. explain. FIG. 3 shows the relationship between the air filter 8, the filter guide 3 a integrally formed on the front panel 3, and the heat exchanger 9. Although the heat exchanger 9 has a dividing surface on the upper side and the front side, the dividing surface on the upper side is covered with a shield which is separately formed although not shown. On the other hand, the front dividing surface of the heat exchanger 9 needs the shield 13 for preventing the above-mentioned useless air flow and scattering of dew condensation water. In this embodiment, this shield 13 is used as a filter guide. It is integrated with the back of 3a. The upper surface of this shield 13 is inclined rearward along the fin cross section of the upper heat exchanger 9, so that the condensed water flowing down from the upper heat exchanger 9 can surely flow down to the lower heat exchanger 9. You can

[0008]

[Effect of device]

 In the case of the indoor unit configured as described above, the shield formed on the back surface of the filter guide blocks the flow of useless air and also receives the condensed water flowing down from the upper heat exchanger. As a result, dew condensation water is prevented from scattering, and the air filter and the inside of the machine are not wet with dew condensation water, so mold is prevented and hygienic air conditioning is obtained. Further, since the front panel and the shield are integrated, the labor for assembling is omitted, which is advantageous in terms of cost.
