[0060] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0061] In the present application, the air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to cool or heat the indoor space.

[0062] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0063] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0064] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0065] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0066] The present application proposes an indoor unit of an air conditioner, which includes an outer shell (not shown), on which an air inlet for introducing external airflow and an air outlet for outputting the airflow into the room are formed.

[0067] An air inlet channel is formed between the air inlet and the air outlet. A purification device is arranged in the air inlet channel to filter the airflow passing through the air inlet channel. The filtered airflow is output from the air outlet, which can improve the quality of air introduced into the room.

[0068] refer to Figure 1 The purification device includes an electric control assembly 100, a support component and a purification component 200. The support component is fixed in the air inlet channel, the electric control assembly 100 is arranged above the support component, and the electric control assembly 100 is connected to the support component.

[0069] A support frame is formed between the electric control assembly 100 and the support component, and the purification component 200 is installed in the support frame.

[0070] The airflow in the air inlet channel passes through the purification component 200 at an angle and is purified by the purification component 200.

[0071] In some embodiments of the present application, the purification component 200 is vertically arranged in the air inlet channel, located on the upstream side of the indoor heat exchanger. After the airflow is processed by the purification component 200, it enters the indoor heat exchanger for heat exchange.

[0072] The flow direction of the airflow in the air inlet channel is perpendicular to the windward surface of the purification component 200 to improve the air intake efficiency.

[0073] refer to Figure 2Specifically, the support assembly includes a bottom support member 400 and a side support member 300 connected between the electric control assembly 100 and the bottom support member 400. Specifically, the support frame is formed by surrounding the electric control assembly 100, the bottom support member 400 and the side support member 300.

[0074] The purification component 200 includes a filter element and / or an electrostatic adsorption module 220 that are arranged at an angle to the flow direction of the airflow, and the filter element and / or the electrostatic adsorption module 220 are connected to the support frame.

[0075] Among them, a mounting portion is formed on the electric control assembly 100, a limiting portion is formed on the bottom support member 400, and the purification component 200 is detachably connected between the mounting portion and the limiting portion.

[0076] In some embodiments of the present application, the purification component 200 includes a first filter element 210, an electrostatic adsorption module 220 and a second filter element 230 arranged at intervals along the flow direction of the airflow, and the first filter element 210, the electrostatic adsorption module 220 and the second filter element 230 are respectively detachably connected in the support frame.

[0077] The first filter element 210 and the second filter element 230 are respectively disposed on both sides of the electrostatic adsorption module 220 , and the airflow passes through the first filter element 210 , the electrostatic adsorption module 220 , and the second filter element 230 in sequence.

[0078] The electrostatic adsorption module 220 is specifically a high-voltage electrostatic adsorption module 220, which purifies the air mainly by charging dust particles with multiple groups of mutually insulated grids and electrodes with positive and negative high-voltage static electricity, and then absorbs the charged substances through the action of electric field force.

[0079] Since the electric field force generated by high-voltage static electricity can penetrate any object, under the action of the high-voltage static field, any small dust particles can be charged through electrostatic induction and generate Coulomb force, which are then absorbed by the grid and electrode plates with opposite charges, thereby purifying the air.

[0080] The electrostatic adsorption module 220 is electrically connected to the electric control assembly 100 , and the electric control assembly 100 supplies power to the electrostatic adsorption module 220 .

[0081] The electric control assembly 100 is provided with a power supply line for connecting to an external power source.

[0082] Specifically, the mounting portion includes a mounting recess, which is formed on the bottom surface of the electric control assembly 100 and extends upward.

[0083] The mounting recesses are arranged along the width direction of the electric control assembly 100 , so that the purification component 200 is installed on the electric control assembly 100 in a transverse direction.

[0084] Specifically, the mounting recess is used to connect the first filter element 210 and the second filter element 230 .

[0085] refer to Figure 3 , Figure 8 The first filter element 210 and the second filter element 230 respectively include a filter frame 211 and a filter portion 212 , and the peripheral side of the filter portion 212 is fixed on the filter frame 211 .

[0086] The mounting recess includes a first mounting recess 110 and a second mounting recess 120 . The top of the first filter element 210 is inserted into the first mounting recess 110 , and the top of the second filter element 230 is inserted into the second mounting recess 120 .

[0087] During disassembly, the first filter element 210 and the second filter element 230 are removed from the first mounting recess 110 and the second mounting recess 120 respectively.

[0088] refer to Figure 4 , Figure 5 Specifically, the first mounting recess 110 and the second mounting recess 120 both include an inclined portion 1101 and an avoidance portion 1102 .

[0089] The inclined portion 1101 is formed at the opening of the mounting recess and tapers in a bottom-up direction.

[0090] The avoidance portion 1102 is located above the inclined portion 1101 , and outwardly expanding avoidance cavities are formed on both sides of the avoidance portion 1102 . The distance between the top surface of the mounting portion and the bottom support member 400 is greater than the height of the purification component 200 .

[0091] Taking the installation method of the first filter element 210 as an example;

[0092] refer to Fig.10 , Fig.11 During installation, the top of the first filter element 210 is first inserted into the first installation recess 110. During the installation process, the first filter element 210 is inserted along one side of the inclined portion 1101 until the top of the first filter element 210 contacts the inner wall of the avoidance cavity of the avoidance portion 1102.

[0093] In this state, the bottom of the first filter element 210 is located above the limiting portion. Subsequently, the first filter element 210 is erected and moved downward to be connected with the limiting portion.

[0094] The top of the first filter element 210 in the connected state is a certain distance above the avoidance portion 1102, which is convenient for disassembly.

[0095] During disassembly, the first filter element 210 is lifted up until the bottom of the first filter element 210 moves above the avoidance portion 1102 , and then the bottom of the first filter element 210 is tilted in the disassembly direction to disassemble the first filter element 210 .

[0096] The installation and disassembly method of the second filter element 230 is similar to that of the first filter element 210. Since the inclined portion 1101 and the avoidance portion 1102 are both front-to-back symmetrical structures, the first filter element 210 and the second filter element 230 can be removed from the front and rear sides of the purification component 200 respectively.

[0097] The specific connection method of the electrostatic adsorption module 220 is as follows:

[0098] The mounting portion further includes an elastic power supply portion 140 formed below the electric control assembly 100 , and the elastic power supply portion 140 includes two electrode sheets spaced apart.

[0099] The elastic power supply unit 140 is used to supply power to the electrostatic adsorption module 220 .

[0100] Both ends of the electrode sheet are fixed below the electric control assembly 100 , an elastic gap is formed between the middle position of the elastic power supply part 140 and the electric control assembly 100 , and the top of the electrostatic adsorption module 220 is in contact with and connected to the elastic power supply part 140 .

[0101] refer to Fig. 9 Specifically, the electrostatic adsorption module 220 includes an adsorption frame 222 and an adsorption portion 221 formed in the adsorption frame 222 . A docking portion 223 is provided on the top of the adsorption frame 222 for contacting and connecting with the elastic power supply portion 140 , so that the electric control assembly 100 supplies power to the electrostatic adsorption portion 221 .

[0102] That is, the electrode sheet forms a certain elasticity along the direction of approaching or moving away from the electric control assembly 100. When the electrostatic adsorption module 220 is installed, the electrode sheet moves toward the electric control assembly 100 under the action of the electrostatic adsorption module 220, so that the electrode sheet is in stable contact with the electrostatic adsorption module 220, and the electrostatic adsorption module 220 is stably powered.

[0103] When the electrostatic adsorption module 220 is disassembled, the operator continues to move the electrostatic adsorption module 220 upward, and the electrode sheet continues to be compressed toward the electronic control assembly 100 until the bottom of the electrostatic adsorption module 220 moves to above the limit portion, and then the electrostatic adsorption module 220 is tilted and moved out of the support frame.

[0104] refer to Figure 6 Specifically, the limiting portion includes a first limiting portion 411 , a second limiting portion 412 and an intermediate limiting portion 413 formed on the bottom support member 400 , and the intermediate limiting portion 413 is located between the first limiting portion 411 and the second limiting portion 412 .

[0105] The first limiting portion 411 is located directly below the first mounting recess 110 , the second limiting portion 412 is located directly below the second mounting recess 120 , and the middle limiting portion 413 is located directly below the electrode sheet.

[0106] The bottom of the first filter element 210 is connected to the first limiting portion 411 , the bottom of the second filter element 230 is connected to the second limiting portion 412 , and the bottom of the electrostatic adsorption module 220 is connected to the middle limiting portion 413 .

[0107] Then, the first filter element 210, the second filter element 230 and the electrostatic adsorption module 220 are vertically fixed in the supporting frame.

[0108] Specifically, the first limiting portion 411, the second limiting portion 412 and the middle limiting portion 413 each include two limiting units disposed at an interval, and the first limiting portion 411, the second limiting portion 412 and the middle limiting portion 413 are respectively connected between the corresponding two limiting units.

[0109] Each limiting unit has a certain height and is configured so that when the first filter element 210, the electrostatic adsorption module 220 and the second filter element 230 move to the highest position in the support frame, the bottom of the first filter element 210, the electrostatic adsorption module 220 and the second filter element 230 is higher than the corresponding limiting unit.

[0110] The first filter element 210, the second filter element 230 and the electrostatic adsorption module 220 can be installed and removed from either the front or rear side of the support frame, and both sides can be installed and removed. The installation of the first filter element 210, the second filter element 230 and the electrostatic adsorption module 220 does not need to rely on fastening screws or the like, which improves the efficiency of installation and removal, reduces the labor cost of operators, and is conducive to saving operating space, realizing the miniaturized design of the air-conditioning indoor unit, and saving costs.

[0111] The bottom support member 400 is connected and fixed to the side support member 300 . Specifically, the bottom support member 400 includes a bottom support plate 410 and bending portions 420 formed on both sides of the support plate.

[0112] Connecting portions 421 extending to the outside of the bottom support plate 410 are formed at both ends of the bent portion 420 .

[0113] refer to Figure 7 The side support member 300 includes a support vertical plate 310 and a connecting outer edge 320 formed on both sides of the support vertical plate 310 , and the connecting outer edge 320 is fixed on the connecting portion 421 .

[0114] Specifically, a connection hole 321 is provided at the bottom of the connection outer edge 320 , and the connection hole 321 is fixed to the connection portion 421 by fastening bolts or other fasteners.

[0115] A plurality of fixing holes 322 are also arranged at intervals on the connecting outer edge 320 for fixing in the air inlet channel to achieve connection and fixation of the supporting assembly.

[0116] Both ends of the electric control assembly 100 are fixed between two side supports 300 .

[0117] Two control units 130 are formed on the electric control assembly 100, and the control units 130 are respectively formed on the opposite front end surface and rear end surface. The control units 130 on both sides can control the purification device. The relevant circuit connection that can realize two-way control is the existing technology and will not be described in detail here.

[0118] The user can control the purification device in the front and rear directions separately, which is more convenient. There is no need to distinguish the front and back sides of the purification device installed in the outer shell, which is conducive to reducing installation errors and can effectively prevent the problem of wrong installation of electronic purification. The installation is simple and quick, and it is also suitable for certain two-way air supply scenarios.

[0119] In other words, the purification component 200 is connected to the support component through the installation part and the limiting part, and does not need to rely on structures such as fastening screws for installation and fixation. It has low cost and improved assembly and disassembly efficiency, which is beneficial to reduce the labor cost of operators, save operating space, and help to achieve a miniaturized design of the air-conditioning indoor unit.

[0120] In addition, the purification component 200 can be installed or removed from either the front or rear side of the support frame. The user can remove the purification component 200 from the front or rear side according to the actual installation environment, which has high flexibility.

[0121] The present application also proposes an air conditioner indoor unit, which includes an outer shell and a purification device. An air inlet and an air outlet are formed on the outer shell, an air inlet channel is formed between the air inlet and the air outlet, and the purification device is installed in the air inlet channel.

[0122] The purification device includes an electric control assembly 100, a purification component 200 and a supporting component.

[0123] The purification device is installed in the outer shell, and the purification component 200 includes a filter element and / or an electrostatic adsorption module 220 set at an angle to the flow direction of the airflow. The filter element and / or the electrostatic adsorption module 220 are installed in the air inlet channel through a supporting component.

[0124] The support assembly is configured such that, when disassembled, the purification assembly 200 can be disassembled from the front side or the rear side of the support assembly to improve the assembly and disassembly efficiency of the purification assembly 200 .

[0125] The structure of the support assembly can be realized in the following ways:

[0126] Method 1:

[0127] refer to Fig.12 In some embodiments of the present application, the support component specifically includes a support frame formed by sheet metal welding, and the electronic control assembly 100 and the purification component 200 are installed in the support frame.
