Air conditioner indoor unit

Abstract

In commonly used air conditioning indoor units, due to the positional relationship or structural issues of the heat exchanger, air supply fan, left and right air guide plates, and upper and lower air guide plates arranged inside the filter, special tools and professional techniques must be used to clean the heat exchanger and water tray. The air supply fan and left and right air guide plates are also difficult to clean. In order to solve such problems, this invention provides a solution that redesigns the positional shape of the heat exchanger, water tray, air supply fan, left and right air guide plates, and upper and lower air guide plates. A cleaning air conditioning indoor unit is characterized in that the air drawn in by the air intake (4) passes through the air intake air passage (5) and undergoes heat exchange by the heat exchanger (8) arranged inside the water tray (17). The air then flows through the air supply fan (13) to the left and right air guide plates (14) and the upper and lower air guide plates (15) and is blown out to the outside of the indoor unit body (1). The heat exchanger (8) can be cleaned inside the water tray (17), and the integrated air supply unit (16) and water tray (17) can be disassembled and assembled separately from the indoor unit body (1).

Description

Technical Field

[0001] This invention relates to indoor units of household air conditioners. Background Technology

[0002] Common household air conditioner indoor units that require regular maintenance are difficult to clean due to the configuration of components such as heat exchangers, air supply fans, upper and lower air guides, left and right air guides, and water trays. Currently, there is no solution that allows for easy cleaning of the air supply fan, upper and lower air guides, and left and right air guides individually or as components through a single operation; no solution that allows for easy cleaning of the heat exchanger while it is immersed in cleaning fluid in the water tray; and no solution that allows for heat exchange to be performed within the water tray.

[0003] The wall-mounted air conditioner indoor unit of Patent Document 1 is characterized by a structure in which the air supply fan, which can be easily disassembled and installed, is fixed to the motor shaft inside the indoor unit without screws or the like. This allows the air supply fan to be removed and cleaned. When reassembled, it also has a structure that allows it to be smoothly inserted through the fan guide part located in the center of the indoor unit and the motor shaft, which is shaped like the front end of a four-sided pyramid. However, this solution only pulls the air supply fan out from the side of the main unit, which is different from the structure of the present invention, which pulls out the entire unit from the front. In addition, it is different from the present invention, which has a basic structure that allows heat exchange to be performed in the water tray and allows the heat exchanger itself to be cleaned in the water tray.

[0004] Furthermore, in the wall-mounted air conditioner indoor unit of Patent Document 2, in order to improve the ease of disassembly and assembly of the air conditioner indoor unit, a wind duct assembly consisting of a frame, a grille assembly, a first panel, and a second panel is constructed and detachably connected to the base, which enables thorough cleaning of the air duct of the air conditioner indoor unit. This is different from the present invention, which is based on the ability to perform heat exchange in a water tray and to clean the heat exchanger itself in the water tray.

[0005] Furthermore, the wall-mounted air conditioner indoor unit of Patent Document 3 utilizes a base including a frame and air duct components to form an inner cavity with a downward opening. The air duct components include a fan mounting frame, which is movably mounted to the base and can move outward from the opening of the inner cavity in a vertical direction. Because the air supply fan and mounting frame can be removed and cleaned together, the user can easily clean the air duct components. This differs from the present invention, whose basic structure allows heat exchange within a drip tray and the heat exchanger itself to be cleaned within the drip tray. The similarity between the detachable air supply unit, consisting of an air supply fan, left and right air guide vanes, and up and down air guide vanes, and the present invention with a drip tray is only that the structure of the air duct components, including the fan inside the detachable indoor unit, can be cleaned.

[0006] Furthermore, in the air conditioner of Patent Document 4, which has a heat exchanger and a device for drawing out drainage on the drip tray, the drainage is drawn out and no drainage is left in the drip tray in order to suppress the generation of bacteria in the drainage. This is different from the present invention, which has a heat exchanger that conducts heat exchange on the intake air in the drip tray and cleans the heat exchanger in the drip tray.

[0007] Similarly, in the indoor unit of the air conditioning device of Patent Document 5, which has a heat exchanger arranged on a drip tray, the purpose is to clean the heat exchanger efficiently. This is different from the present invention, which cleans the heat exchanger by immersing it in a drip tray filled with cleaning fluid. In the heat exchanger arranged vertically in the drip tray, a water-stop panel is used to block the cleaning fluid blown from the horizontal direction. This can also be said to be different from the present invention, which cleans the heat exchanger in the drip tray.

[0009] The problem that the invention aims to solve

[0010] For commonly used wall-mounted household air conditioner indoor units, although those sold on the market can automatically and easily clean the filters and heat exchangers, thorough cleaning of the heat exchanger, fan, upper and lower air guides, left and right air guides, and drip tray still requires professional cleaning and incurs high cleaning costs. Therefore, most units are left to accumulate dirt. This contributes to reduced heat exchange efficiency, mold growth, and dirt buildup.

[0011] To address this problem, the present invention provides a cleaning air conditioner indoor unit that allows for easy removal and cleaning of the air supply fan, upper and lower air guide plates, and left and right air guide plates without tools, and heat exchange in the water collection tray, thereby enabling simple cleaning of the heat exchanger.

[0012] Technical solutions for solving technical problems

[0013] An indoor air conditioner unit has a filter 3, an air intake 4, an air intake passage 5, a partition wall a6, an air outlet 7, a heat exchanger 8, a water collection tray 17, and an integrated air supply unit 16 in the indoor unit body 1. The heat exchanger 8 is disposed in the water collection tray 17. The characteristic is that the air drawn in by the air supply fan 13 from the air intake 4 of the indoor unit body 1 is drawn into the inner side of the water collection tray 17 through the air intake passage 5 formed by the partition wall a6. After heat exchange by the heat exchanger 8 disposed in the water collection tray 17, the air is blown out of the indoor unit body 1 from the air outlet 7 of the indoor unit body 1 by the integrated air supply unit 16.

[0014] An indoor unit of an air conditioner is characterized in that, in an indoor unit body 1 having a water tray 17, a drain outlet 18, a drain valve 19, and a drain connection 20, and having a heat exchanger 8 provided inside the water tray 17 relative to the indoor unit body 1, the air drawn in from the air intake 4 undergoes heat exchange inside the water tray 17. Furthermore, with the water tray 17 installed on the indoor unit body 1 of the air conditioner, the heat exchanger 8 inside the water tray 17 can be cleaned by immersing it in cleaning fluid 46, or by simultaneously flushing the heat exchanger 8 inside the water tray 17 with cleaning fluid 46.

[0015] An indoor unit of an air conditioner is characterized in that the air supply fan 13, the left and right air guide vanes 14, the up and down air guide vanes 15, and the partition wall b24 have a structure that can be disassembled and assembled without tools and constitute an integrated air supply unit 16 with an embedded structure relative to the indoor unit body 1. By removing the integrated air supply unit 16 or the filter 3 from the indoor unit body 1, at least one of the upper, front, back, and left and right side faces of the heat exchanger 8 located in the water tray 17 is exposed, so that the integrated air supply unit 16 removed from the indoor unit body 1 can be directly cleaned, or the air supply fan 13, the left and right air guide vanes 14, and the up and down air guide vanes 15 can be removed from the integrated air supply unit 16 for cleaning.

[0016] Invention Effects

[0017] Even at home, the heat exchanger located inside the drip tray can be easily cleaned, either by placing it directly in the tray or by immersing it in cleaning fluid stored in the tray. Compared to conventional systems, the fan, upper and lower air deflectors, left and right air deflectors, and drip tray can be easily removed for cleaning, eliminating the need for regular professional maintenance required for traditional wall-mounted residential air conditioner indoor units. This significantly reduces maintenance costs and encourages the replacement of air conditioning units beyond their service life. Furthermore, this invention, which allows for direct cleaning of the heat exchanger inside the drip tray, can be applied to automotive air conditioning units. By placing the heat exchanger outdoors, such as in the engine compartment, cleaning the heat exchanger does not require disassembling the dashboard or the air conditioning unit. This allows users to easily and frequently clean the unit themselves, preventing mold allergies. Furthermore, according to the present invention, by equipping the air intake with an ion generator or the like, negative ions or the like can be used to sterilize the air supply fan, upper and lower air guide plates, left and right air guide plates, water tray, and heat exchanger located inside the indoor unit and inside the indoor unit during operation.

Detailed Implementation

[0026] like Figure 1 (a)(b) Figure 4 (a)(b)(c)(d) Figure 8 (a)(b) Figure 9As shown in (a), (b), (c), (d), and (e), the indoor unit body 1 includes an indoor unit body frame 2, a filter 3, an air intake 4, an air intake air duct 5, a partition wall a6, an air outlet 7, a heat exchanger 8, refrigerant pipe a11, refrigerant pipe b12, a drip tray 17, a drain outlet 18, a drain valve 19, a drain connection 20, a main body drain connection 21, a main body drain hose 22, an air outlet air duct 23, a partition wall b24, a power unit 25, a base unit 26, a drain connection cover 32, a base unit storage unit 33, and an integrated air supply unit 16 equipped with a blower fan 13, left and right air guide vanes 14, and up and down air guide vanes 15. A filter is located on the upper part of the indoor unit body 1. Air intake 3 and air intake 4, reaching from the lower end to the partition wall a6 of heat exchanger 8 inside water tray 17, form air intake air passage 5. Heat exchanger 8 is arranged inside water tray 17 installed at the bottom of indoor unit body 1. An integrated air supply unit 16 is arranged on the upper part of heat exchanger 8. Air drawn in from air intake 4 with filter 3 by air supply fan 13 is introduced into the inside of water tray 17 through air intake air passage 5. After heat exchange by heat exchanger 8 inside water tray 17, air is sent out by air supply fan 13 to left and right air guide vanes 14 and up and down air guide vanes 15 arranged in integrated air supply unit 16, and blown out from air outlet 7 of indoor unit body 1 to the outside of indoor unit body 1. In addition, air intake 4 is arranged on the upper surface of indoor unit body 1, and air outlet 7 is arranged on the front surface of indoor unit body 1, but not limited thereto. Furthermore, the arrangement of the air intake 4, integrated air supply unit 16, heat exchanger 8, and drip tray 17 from the top of the indoor unit body 1 is not limited to this. Additionally, the shape of the air intake path 5, formed by the indoor unit body 1 and partition walls a6 and b24, leading to the heat exchanger 8 within the drip tray 17, is not limited to this. Furthermore, as... Figure 9 As shown in (d) and (e), there are also cases where the partition wall b24 is not present. In addition, regarding the partition walls a6 and b24, there are also configurations that can be disassembled and reassembled during cleaning.

[0027] like Figure 4 (a)(b)(c)(d) Figure 8 As shown in (a) and (b), when an integrated air supply unit 16 is arranged on the upper part of the heat exchanger 8, when the integrated air supply unit 16 or the integrated air supply unit 16 and the partition wall b24 are removed from the indoor unit body 1, the upper part of the heat exchanger 8 arranged inside the water receiving pan 17 is exposed, but not limited to this, in addition to the upper part of the heat exchanger 8, it also includes the form in which all or any one of the front, back, left side and right side are exposed.

[0028] like Figure 9As shown in (a), (b), (c), (d), and (e), even when a filter section 3 is provided on the upper or front part of the heat exchanger 8, when the filter section 3 is removed from the indoor unit body 1, the upper part of the heat exchanger 8 located inside the water tray 17 is exposed. However, it is not limited to this. In addition to the upper part of the heat exchanger 8, it also includes the form in which all or any one of the front surface, back surface, left side surface, and right side surface are exposed.

[0029] Figure 4 (b) indicates that the air entering from the air intake 4 where the filter section 3 of the indoor unit body 1 of the present invention is located, flows through the air intake air passage 5 formed by the partition wall a6, which has a curved cross-section when viewed from the side, passes through the heat exchanger 8 in the structure provided inside the air conditioning indoor unit, is transported from the partition wall b24 to the integrated air supply unit 16, and is delivered from the air outlet 7 through the air blowing air passage 23. It also indicates the indoor unit body 1 when the bottom of the integrated air supply unit 16 and the partition wall b24 are integrally constructed when viewed from the right side of the front, but the placement of the partition wall b24 is not limited to this. Furthermore, as... Figure 9 As shown in (a), (b), (c), (d), and (e), the shape of the airflow path 23 is not limited to this. Furthermore, in Figure 4 In (b), the partition wall a6 separates the air intake path 5 and the air exhaust path 23.

[0030] exist Figure 4 In (b) of the present invention, in the indoor unit of the air conditioner, the air drawn in by the air supply fan 13 from the air intake 4 with filter 3 on the upper surface of the indoor unit body 1 is introduced into the inner side of the water tray 17 through the air intake air passage 5 on the back side of the indoor unit body 1 separated by the partition wall a6. The air then enters the lower surface of the heat exchanger 8 provided in the water tray 17 from the lower end of the partition wall a6. After heat exchange in the heat exchanger 8, the air is drawn up from the upper surface of the heat exchanger 8 by the air supply fan 13 along the partition wall b24 and then sent out by the left and right air guide vanes 14 and the up and down air guide vanes 15. The air is blown out from the air outlet 7 of the indoor unit body 1 to the outside of the indoor unit body 1. However, the respective configuration positions and shapes of the partition wall a6, the water tray 17, the integrated air supply unit 16, and the heat exchanger 8, as well as the shape of the air flow into the heat exchanger 8 provided in the water tray 17, are not limited to this.

[0031] like Figure 2 (a)(b)(c) Figure 4 (a)(b) Figure 7 (c)(d)(e) Figure 8As shown in (a) and (b), in the indoor unit of the air conditioner of the present invention, the state in which the heat exchanger 8 is immersed in the cleaning fluid 46 stored in the water tray 17 of the structure provided inside the indoor unit of the air conditioner refers to the state in which the entire or part of the heat exchanger 8 is immersed in the cleaning fluid 46 injected into the water tray 17 with the drain valve 19 closed, and the heat exchanger 8 is wiped by a brush or the like, and the heat exchanger 8 can be cleaned while flushing out the cleaning fluid 46. (8) refers to the state in which, with the drain valve 19 open, the water tray 17 is filled with pressurized cleaning fluid 46 blown by a cleaning device having multiple or one small hole, and the cleaning fluid 46 is discharged from the drain port 18 while cleaning is performed; while flushing out the cleaning fluid 46 and discharging it from the drain port 18, the heat exchanger 8 is wiped by a brush or the like, and the heat exchanger 8 arranged inside the water tray 17 of the structure provided inside the indoor unit of the air conditioner is cleaned. In addition, when the cleaning fluid 46 is discharged, the external drain hose connection 27 or the main body drain connection 21 is connected to the drain connection 20. Furthermore, the components installed inside the air conditioner indoor unit, which can be detached from the indoor unit body 1, can also be removed from the indoor unit body 1, and only the components installed inside the air conditioner indoor unit themselves can be cleaned. Additionally, when the air conditioner is running, the main body drain connection 21 is connected to the drain connection 20. Moreover, the cleaning fluid used when cleaning the partition wall a6, partition wall b24, and the air intake air passage 5 of the indoor unit body 1 can flow into the drip tray 17.

This configuration involves a single heat exchanger 8 placed horizontally inside the drip tray 17. However, it is not limited to this configuration; heat exchangers 8 with multiple surfaces or multiple vertically arranged heat exchangers 8 may also be disposed inside the drip tray 17. Furthermore, the shape of the heat exchanger 8 may include cylindrical or similar forms.

However, the disassembly and assembly mechanism of the structure installed in the indoor unit of the air conditioner is not limited to this, and other disassembly and assembly mechanisms and locking mechanisms may also be configured.

[0034] like Figure 1 (b) Figure 3 (a)(b)(c)(d) Figure 4 As shown in (c) and (d), the structure for disassembling and assembling the integrated air supply unit 16 that is fitted into the indoor unit body 1 is to release the lock of the air supply unit locking part 34 so that the integrated air supply unit 16 slides back and forth on the track of the body 1. However, the disassembly and assembly structure of the integrated air supply unit 16 is not limited to this.

[0035] like Figure 7 As shown in (a) and (b), the drain connection 20 and the main body drain connection 21 are designed to be detachable, using accessory types and internal or external thread connections. Furthermore, in the figures, the main body drain connection 21, the main body drain hose 22, and the drain connection cover 32 are positioned on the lower right front of the indoor unit body 1, while the drain outlet 18, the drain valve 19, and the drain connection 20 are positioned on the front right front side of the water collection tray 17 of the structure installed inside the air conditioning indoor unit. However, the positions of the drain outlet 18, the drain valve 19, and the drain connection 20 are not limited to these.

[0036] like Figure 2 As shown in (a), (b), and (c), a structure is adopted that makes the main drain hose 22 flexible, flexible, and rotatable, and makes it easy to replace the external drain hose 28.

[0037] like Figure 1 (b) Figure 3 As shown in (a), (b), (c), (d), (e), (f), (g), and (h), when the longitudinal, lateral, and height dimensions of the detachable drip tray 17 are set to accommodate the integrated air supply unit 16, cleaning can be performed after removal from the indoor unit body 1. Furthermore, water or cleaning fluid 46 can be stored in the drip tray 17 removed from the indoor unit body 1 to clean the air supply fan 13, the left and right air guide vanes 14, the up and down air guide vanes 15, or the integrated air supply unit 16. Additionally, when the integrated air supply unit 16 is equipped with a power unit section 25, the power unit section 25 of the integrated air supply unit 16 is waterproof.

The rotational force of the air supply fan 13 arranged on the integrated air supply unit 16 and the driving force of the left and right air guide vanes 14 and the up and down air guide vanes 15 are transmitted from the power unit 25 in the integrated air supply unit 16. The power and electrical signals transmitted to the power unit 25 are obtained from the main body base unit 26 using a power cord with connectors and sockets, but it is not limited to this and other connection structures are also possible. In addition, besides the air supply fan 13, the left and right air guide vanes 14 and the up and down air guide vanes 15 can also be operated manually, or one of them can be operated manually.

[0044] Figure 5 (a)(b)(c)(d) and Figure 6 (a) and (b) are the rotational force or driving force transmission section and the rotational force or driving force receiving section when the power unit 25 is not arranged in the integrated air supply unit 16. The diagram shows the structure of the air supply fan rotational force transmission section 40, the left and right air guide vane driving force transmission section 42 arranged on the indoor unit body 1 side, and the air supply fan rotational force receiving section 41, the left and right air guide vane driving force receiving section 43, and the up and down air guide vane driving force receiving section 45 arranged on the integrated air supply unit 16 side relative to the up and down air guide vane driving force transmission section 44. In the structure of the air supply fan rotational force transmission section 40 and the air supply fan rotational force receiving section 41, gear meshing, electromagnetic clutch, permanent magnet, socket, etc., or combinations thereof are used. The relationship of rotational force transmission and reception shown in the diagram of the air supply fan rotational force transmission section 40 and the air supply fan rotational force receiving section 41 is not limited to this. Furthermore, the relationship between the transmission and reception of driving force in the left and right wind deflector driving force transmission section 42 and the left and right wind deflector driving force receiving section 43, as well as the relationship between the up and down wind deflector driving force transmission section 44 and the up and down wind deflector driving force receiving section 45, is not limited to these.

[0045] Figure 1 (b) Figure 3 (b)(c)(d) Figure 4 The air supply fan 13 shown in (a), (b) and (c) is a crossflow fan (registered trademark), but is not limited thereto and may be other fans.

[0046] like Figure 4As shown in (a), (b), and (d), by arranging the electromagnetic unit 29 and the like at the air intake 4, the proliferation of mold and other airborne bacteria in various parts inside the indoor unit body 1, such as the water collection tray 17, heat exchanger 8, blower fan 13, left and right air guide vanes 14, and up and down air guide vanes 15, which are arranged between the air intake 4 and the air outlet 7, can be suppressed. Furthermore, the electromagnetic unit 29 and the like have functions such as negative ion generation and plasma generation.

[0047] like Figure 1 (b) Figure 4 (a)(b)(c)(d) Figure 7 As shown in (c), (d), and (e), in the indoor unit of the air conditioner of the present invention, a heat exchanger 8 is disposed inside the water tray 17 of the structure provided in the indoor unit of the air conditioner, and the heat exchanger 8 can be cleaned in the water tray 17. This solution can also be applied to vehicle air conditioners. By disposing the heat exchange unit in the engine compartment or the like outside the driver's seat, the dashboard in the driver's seat can be removed, and the internal cleaning of the heat exchange unit with the heat exchanger 8 can be performed without disassembling the main body of the air conditioner unit.
