Description

Technical Field

[0001] The present invention relates to a household air conditioner indoor unit.

Background Art

[0002] Conventional household air conditioner indoor units that require regular maintenance are structured in such a way that due to problems with the arrangement of components such as heat exchangers, blower fans, flaps, louvers, and drain pans, they cannot be easily cleaned by anyone. There is no currently confirmed form that allows for the easy removal and cleaning of the blower fan, flap, and louver individually or as a unit with a single touch, a form that allows for easy cleaning with the heat exchanger immersed in the cleaning liquid stored in the drain pan, or a form that arranges the heat exchanger in the drain pan and conducts heat exchange within the drain pan.

[0003] The wall-mounted air conditioner indoor unit of Patent Document 1 is characterized by a structure in which a blower fan that can be easily detached is arranged on the motor shaft inside the indoor unit without being fixed with screws or the like, so that the blower fan can be taken out and cleaned. When it is put back, it has a structure that can smoothly fit with the fan guide provided in the central part of the indoor unit and the motor shaft with a quadrangular pyramid tip shape. However, morphologically, only the blower fan is pulled out from the side of the main body unit, which has a different structure from the present invention that pulls out the unit from the front as a whole. Additionally, it is different from the present invention, which has a basic structure that allows for heat exchange within the drain pan and the cleaning of the heat exchanger itself within the drain pan.

[0004] And the wall-mounted air conditioner indoor unit of Patent Document 2 is characterized by a structure that enables thorough cleaning of the air conditioner indoor unit air passage by a structure of an air passage assembly composed of a frame, a grid assembly, a first panel, and a second panel that are detachably connected to the base, in order to improve the convenience of detaching and attaching the air conditioner indoor unit. It is different from the present invention, which has a basic structure that allows for heat exchange within the drain pan and the cleaning of the heat exchanger itself within the drain pan.

[0005] In addition, the wall-mounted air conditioner indoor unit of Patent Document 3 forms an inner chamber having a downward opening with a base including a frame and an air duct component. The air duct component includes a fan mounting frame, and the mounting frame itself is attached to the base so as to be movable, and can move outward from the opening of the inner chamber along the vertical direction. With a structure that allows the blower fan to be removed and cleaned together with the mounting frame, the user can easily clean the air duct component. However, it is different from the present invention having a basic structure in which heat exchange is performed in the drain pan and the heat exchanger itself can be cleaned in the drain pan. The similarity between the present invention having a detachable blower unit including a blower fan, left and right air direction louvers, and an up and down air direction flap, and a structure in which a drain pan is disposed is only a structure that allows the air duct component including the fan inside the detachable indoor unit to be cleaned.

[0006] Furthermore, the air conditioner of Patent Document 4 having a heat exchanger and a device for sucking drain water on the drain pan is a structure that sucks drain water so that drain water does not accumulate in the drain pan in order to suppress the generation of bacteria in the drain water, and exchanges heat of the sucked air with the heat exchanger in the drain pan, and is different from the present invention having a structure for cleaning the heat exchanger in the drain pan.

[0007] Similarly, the indoor unit of the air conditioner of Patent Document 5 in which a heat exchanger is disposed on the drain pan aims to efficiently clean the heat exchanger, but is different from the present invention having a structure in which the heat exchanger is immersed in the drain pan with a cleaning liquid to clean the heat exchanger. It is a structure in which the cleaning liquid sprayed from the horizontal direction is received by a water stop panel on the heat exchanger disposed vertically on the drain pan, and it can also be said that this is different from the present invention having a structure for cleaning the heat exchanger in the drain pan.

Summary of the Invention

Problems to be Solved by the Invention

[0009] Conventional wall-mounted household air conditioner indoor units that can automatically and simply clean the filter and heat exchanger are on the market. However, when thoroughly cleaning the heat exchanger, blower fan, flaps, louvers, and drain pan, it is necessary to rely on a professional, which also requires a large service fee, so dirt is often left uncleaned. This has also led to a decrease in heat exchange efficiency, the growth of mold, and the sticking of dirt.

[0010] To solve these problems, the present invention provides a cleaning air conditioner indoor unit having a structure and form that allows the blower fan, flaps, and louvers to be easily removed and cleaned without tools, allows heat exchange to occur in the drain pan, and allows the heat exchanger to be easily cleaned.

Means for Solving the Problems

[0011] An air conditioner indoor unit having a filter unit 3, an air inlet 4, an air intake passage 5, a partition wall a6, an air outlet 7, a heat exchanger 8, a drain pan 17, and an integrated blower unit 16 in an indoor unit main body 1, wherein the heat exchanger 8 is disposed in the drain pan 17. The air inhaled from the air inlet 4 of the indoor unit main body 1 by the blower fan 13 passes through the air intake passage 5 formed by the partition wall a6, is drawn into the inside of the drain pan 17, and after heat exchange with the heat exchanger 8 disposed inside the drain pan 17, is blown out of the indoor unit main body 1 from the air outlet 7 of the indoor unit main body 1 by the integrated blower unit 16.

[0012] It has a drain pan 17, a drain 18, a drain cock 19, and a drain connection part 20. The drain pan 17, which has a heat exchanger 8 installed inside it with respect to the indoor unit main body 1, has a form in which the air inhaled from the air inlet 4 in the operating indoor unit main body 1 is heat-exchanged inside the drain pan 17. At the same time, with the drain pan 17 attached to the indoor unit main body 1 of the air conditioner, it can be cleaned in a state where the heat exchanger 8 in the drain pan 17 is immersed in the cleaning liquid 46, or it can be cleaned while the cleaning liquid 46 is poured over the heat exchanger 8 in the drain pan 17. This is a characteristic of an air conditioner indoor unit.

[0013] With respect to the indoor unit main body 1, it constitutes an integrated blower unit 16 having a snap-in structure. The blower fan 13, the left and right air direction louvers 14, the up and down air direction flaps 15, and the partition wall b24 have a structure that can be detached without using tools. By removing the integrated blower unit 16 or the filter unit 3 from the indoor unit main body 1, the upper surface, the front surface, the back surface, and the left and right side surface portions of the heat exchanger 8 installed inside the drain pan 17 are exposed. At the same time, the integrated blower unit 16 removed from the indoor unit main body 1 can be cleaned in its original state or with each of the blower fan 13, the left and right air direction louvers 14, and the up and down air direction flaps 15 removed from the integrated blower unit 16. This is a characteristic of an air conditioner indoor unit.

Effects of the Invention

[0014] Even at home, the heat exchanger disposed inside the drain pan can be easily washed inside the drain pan or immersed in the cleaning liquid stored in the drain pan for overall washing. For the blower fan, flap, louver, and drain pan, compared with conventional ones, they can be easily removed for cleaning. Therefore, unlike conventional wall-mounted household air conditioner indoor units, they do not require regular maintenance by professionals. This not only significantly reduces the cost for maintenance management but also can be expected to promote the replacement demand for air conditioner units beyond their service life. Also, the form of the present invention in which the heat exchange part disposed inside the drain pan can be directly washed in the drain pan can also be applied to automotive air conditioner units. By disposing the heat exchange unit outdoors such as in the engine room, it is not necessary to remove the dashboard and disassemble the air conditioner unit for cleaning the heat exchange unit. Thus, users can easily and regularly wash it by themselves, which also helps prevent mold allergies. Furthermore, in the form of the present invention, by disposing an ion generator or the like at the air intake, it is possible to always perform sterilization etc. with negative ions or the like on the blower fan, flap, louver, drain pan, and heat exchanger disposed inside the indoor unit main body and inside the indoor unit during operation.

At the upper part of the indoor unit main body 1, there are a filter part 3 and an air inlet 4. The air intake passage 5 is formed by a partition wall a6 whose lower end reaches the heat exchanger 8 in the drain pan 17. The heat exchanger 8 is disposed in the drain pan 17 mounted on the bottom of the indoor unit main body 1. An integrated air supply unit 16 is disposed above the heat exchanger 8. Air inhaled by the blower fan 13 from the air inlet 4 including the filter part 3 of the indoor unit main body 1 passes through the air intake passage 5 and is drawn into the inside of the drain pan 17, and after heat exchange with the heat exchanger 8 which is in the form of being installed inside the drain pan 17, it is sent to the left and right air direction louvers 14 and the up and down air direction flap 15 disposed in the integrated air supply unit 16 by the blower fan 13, and is blown out of the air outlet 7 of the indoor unit main body 1 to the outside of the indoor unit main body 1. Note that the air inlet 4 is disposed on the upper surface of the indoor unit main body 1 and the air outlet 7 is disposed on the front surface of the indoor unit main body 1, but it is not limited to this form. Also, regarding the positional relationship of the arrangement such as the air inlet 4, the integrated air supply unit 16, the heat exchanger 3, and the drain pan 17 from the upper part of the indoor unit main body 1, it is not limited to this form. Further, regarding the form of the air intake passage 5 formed by the indoor unit main body 1, the partition wall a6, and the partition wall b24 that reaches the heat exchanger 8 in the drain pan 17, it is not limited to this form. Also, there may be a case where there is no partition wall b24 as shown in FIGS. 9(d)(e). Note that the partition wall a6 and the partition wall b24 include forms that can be detached and attached during cleaning.

[0017] As shown in FIGS. 4(a), (b), (c), (d) and FIGS. 8(a), (b), when the integrated blower unit 16 is disposed above the heat exchanger 8, when the integrated blower unit 16 or the integrated blower unit 16 and the partition wall b24 are removed from the indoor unit main body 1, the upper part of the heat exchanger 8 disposed inside the drain pan 17 is exposed. However, it is not limited to this, and in addition to the upper part of the heat exchanger 8, it also includes a form in which all or any of the front, back, left side and right side are exposed.

[0018] As shown in FIGS. 9(a), (b), (c), (d), (e), even when the filter unit 3 is disposed above or in front of the heat exchanger 8, when the filter unit 3 is removed from the indoor unit main body 1, the upper part of the heat exchanger 8 disposed inside the drain pan 17 is exposed. However, it is not limited to this, and in addition to the upper part of the heat exchanger 8, it also includes a form in which all or any of the front, back, left side and right side are exposed.

[0019] FIG. 4(b) shows the flow of air that enters from the air inlet 4 with the filter unit 3 of the indoor unit main body 1 of the present invention, passes through the heat exchanger 8 in the structure installed in the air conditioner indoor unit from the air intake passage 5 whose cross-section of the elevation view when viewed from the side is formed in a curved shape by the partition wall a6, is carried from the partition wall b24 to the integrated blower unit 16, passes through the air outlet passage 23, and is sent out from the air outlet 7. At the same time, it shows the form when the indoor unit main body 1 when the bottom of the integrated blower unit 16 and the partition wall b24 have an integrated structure is viewed from the side from the front right side. However, the location of the partition wall b24 is not limited to this. Also, as shown in FIGS. 9(a), (b), (c), (d), (e), the form of the air outlet passage 23 is not limited to this. In FIG. 4(b), the partition wall a6 is in a form that separates the air intake passage 5 and the air outlet passage 23.

[0020] In Fig. 4(b), for the air conditioner indoor unit of the present invention, the air inhaled from the air inlet 4 with the filter unit 3 on the upper surface of the indoor unit main body 1 by the blower fan 13 passes through the air intake duct 5 on the back side of the indoor unit main body 1 separated by the partition wall a6, and is drawn into the inside of the drain pan 17. From the lower end of the partition wall a6, it wraps around the lower surface of the heat exchanger 8 installed inside the drain pan 17, is heat-exchanged by the heat exchanger 8, and then from the upper surface of the heat exchanger 8, it is sucked up by the blower fan 13 along the partition wall b24, and then sent to the left and right air direction louvers 14 and the up and down air direction flaps 15, and is blown out of the air outlet 7 of the indoor unit main body 1 to the outside of the indoor unit main body 1. However, the arrangement positions and forms of the partition wall a6, the drain pan 17, the integrated blower unit 16, and the heat exchanger 8, and the form of the air flow to the heat exchanger 8 installed inside the drain pan 17 are not limited to this.

[0021] As shown in FIGS. 2(a), (b), (c), FIGS. 4(a), (b), FIGS. 7(c), (d), (e), and FIGS. 8(a), (b), in the air conditioner indoor unit of the present invention, the state where the heat exchanger 8 is immersed in the cleaning liquid 46 stored in the drain pan 17 of the structure installed in the air conditioner indoor unit means that all or part of the heat exchanger 8 is immersed in the cleaning liquid 46 injected into the drain pan 17 with the drain cock 19 closed, and a state where a brush or the like can be rubbed against the heat exchanger 8 for polishing. The form in which the heat exchanger (8) can be cleaned while pouring the cleaning liquid 46 means that in the drain pan 17 with the drain cock 19 open, the pressurized cleaning liquid 46 is sprayed by a cleaning device having a plurality of or one small hole, and the cleaning is performed while discharging the cleaning liquid 46 from the drain 18, and the form of cleaning the heat exchanger 8 disposed inside the drain pan 17 of the structure installed in the air conditioner indoor unit, such as rubbing a brush or the like against the heat exchanger 8 for polishing while pouring the cleaning liquid 46 and discharging it from the drain 18. When discharging the cleaning liquid 46, the drain connection portion 20 is connected to the outdoor drain hose connection portion 27 or the main body drain connection portion 21. In addition, the structure installed in the air conditioner indoor unit that can be attached to and detached from the indoor unit main body 1 can also be cleaned by removing only the structure itself from the indoor unit main body 1 and installing it in the air conditioner indoor unit. When operating the air conditioner, the main body drain connection portion 21 is connected to the drain connection portion 20. In addition, the partition wall a6, the partition wall b24, and the cleaning liquid when cleaning the air intake air passage 5 of the indoor unit main body 1 also flow into the drain pan 17.

[0022] Regarding the form in which the heat exchanger 8 is disposed inside the drain pan 17 of the structure installed in the air conditioner indoor unit that fits into the indoor unit main body 1, as shown in FIGS. 1(b), 2(c), 4(a), (b), (d), 7(c), (d), (e), and 8(a), (b), one heat exchanger 8 is horizontally disposed inside the drain pan 17, but this is not the only case. It is also possible to dispose a heat exchanger 8 having a plurality of surfaces inside the drain pan 17 or to dispose a plurality of vertically arranged heat exchangers 8. Regarding the form of the heat exchanger 8, shapes such as a cylindrical shape are also included.
