Description

Technical Field

[0001] The invention relates to the technical field of air conditioning, and in particular to an evaporator purification device of an air conditioner and a method for adding frost, removing dirt and producing fragrant fresh air. Background Art

[0002] After the air conditioner has been used for a long time, dust will adhere to the outer surface of its evaporator. When the air conditioner is working, the air flow passes through the outer surface of the evaporator and blows the dust off. The dust floats out from the air outlet of the air conditioner with the air flow and spreads into the indoor air, causing certain pollution to the indoor air.

[0003] Some new models of existing air conditioners have introduced a self-cleaning function, which mainly relies on the evaporator's own frost and defrost. The defrost water produced cleans the dirt on the evaporator, and finally converts it into heat for drying and disinfection.

[0004] However, its actual cleaning effect is limited, mainly manifested in the limited thickness of conventional frost, long frost cycle (when the air humidity is low), limited defrost water produced, and unclear cleaning effect, especially the inability to clean stubborn dirt, and the inability to completely eliminate the odor generated by the long-term use of the indoor unit. Summary of the invention

[0075] As described in the background technology, some new models of existing air conditioners have introduced self-cleaning functions, which mainly rely on the evaporator to frost and defrost itself, and the defrosting water produced to clean the dirt on the evaporator, and finally convert it into heat for drying and disinfection. However, its actual cleaning effect is limited, mainly manifested in the limited thickness of conventional frost, the long frosting cycle (when the air humidity is low), the limited defrosting water produced, and the unclear cleaning effect, especially the inability to clean stubborn dirt, and the inability to completely eliminate the odor generated by the indoor unit during long-term use.

[0076] In order to solve the above-mentioned problems in the background technology, the first embodiment of the present invention provides an evaporator purification device for an air conditioner, such as Figure 1a-1i As shown, it includes a plate body 101 and an injection system; a vent 102 is provided on the side of the plate body 101; the injection system includes a liquid pipe group, a liquid pump 201, a nozzle 103, a valve 202, and a liquid storage device 203; the nozzle 103 is arranged on the side of the plate body 101; the liquid pipe group includes a liquid inlet pipe 204 and a liquid outlet pipe 205; the liquid storage device 203 is connected to the liquid inlet of the liquid pump 201 through the liquid inlet pipe 204; the valve 202 is installed on the liquid inlet pipe 204 or the liquid outlet pipe 205; the liquid outlet of the liquid pump 201 is connected to the nozzle 103 through the liquid outlet pipe 205; in this way, the plate body 101 is installed between the filter screen and the middle frame grille of the air conditioner, and the side of the plate body 101 provided with the nozzle 103 faces the evaporator; in the liquid storage device 203 is filled with liquid water; after the air conditioner is turned on for refrigeration, the injection system is controlled to start, valve 202 is opened, liquid pump 201 is started, and nozzle 103 sprays water droplets onto the outer surface of the evaporator.

If the alarm 207 uses a warning light, when the remaining amount of water or detergent or fragrance in the liquid storage device 203 is sufficient, the warning light corresponding to the liquid storage device 203 displays green, and when the remaining amount of water or detergent or fragrance in the liquid storage device 203 is insufficient, the warning light corresponding to the liquid storage device 203 displays red, so as to replenish water or detergent or fragrance in the liquid storage device 203 in time. The remaining amount of water, detergent and fragrance in the liquid storage device 203 can be monitored by using a liquid level sensor or a pressure sensor. When using the liquid level sensor or the pressure sensor, it is electrically connected to the control main board.

[0083] In the first embodiment, the evaporator purification device of the air conditioner further includes a function switching module 208, on which the control mainboard, the alarm 207, and the liquid storage device 203 are respectively mounted, and the function switching module 208 is fixed on the air conditioner casing. Figure 1g The structure referred to by K is the switch of the solenoid valve and the switch of the liquid pump 201. The switch of the solenoid valve, the switch of the liquid pump 201 and the alarm 207 are respectively integrated on the control main board. By switching the switch of the solenoid valve and the switch of the liquid pump 201, different spray function combinations can be switched, for example: spraying water, spraying detergent, spraying fragrance, spraying water and detergent, spraying water and fragrance, spraying detergent and fragrance.

[0084] In the first embodiment, Figure 1h As shown, the nozzle 103 includes at least three injection ports 209 , and the liquid outlet pipes 205 are connected to the injection ports 209 one by one; in this way, each injection port 209 can spray droplets independently without affecting other injection ports 209 .

[0085] It should be understood that it can also be set as follows: Figure 1i As shown, the liquid outlet pipes 205 are first gathered together and then divided to each injection port 209. In this way, water, detergent and fragrance are first gathered and mixed in the process of flowing out from the liquid outlet pipes 205, and then divided to each injection port 209 and injected. The liquid injected onto the outer surface of the evaporator is a mixture of water, detergent and fragrance, and there is no need to wait until frosting and defrosting are completed before gradually mixing, thereby improving the mixing uniformity and making the concentration of the spray liquid detergent and fragrance at various locations on the outer surface of the evaporator more uniform.

[0086] Among them, in the first embodiment, the nozzle 103 is fixedly installed in the pipeline groove 104, and the nozzle is arranged on the side of the second partition 106 away from the first partition 105. After the evaporator purification device of the air conditioner is installed on the air conditioner, the second partition 106 is located between the evaporator and the first partition 105.

[0087] Figure 2a is a schematic flow chart of a frosting and decontamination method in a second embodiment of the present invention; Figure 2b It is a schematic flow chart of another frosting and decontamination method in the second embodiment of the present invention.

[0088] A second embodiment of the present invention provides a method for frosting and decontamination, such as Figure 2a As shown, an evaporator purification device for an air conditioner using any one of the first embodiments of the present invention is applied, wherein the liquid storage device 203 includes at least two liquid storage spaces, and the liquid storage spaces are respectively connected to the liquid inlet of the liquid pump 201 through the liquid inlet pipe 204; and the following steps are included:

[0089] A1: Install the plate 101 between the filter screen and the middle frame grille of the air conditioner, with the side of the plate 101 with the nozzle 103 facing the evaporator;

[0090] A2: Liquid water is filled in one of the liquid storage spaces of the liquid storage device 203;

[0091] A3: After the air conditioner is turned on for cooling, the injection system is controlled to start, the valve 202 is opened, the liquid pump 201 is started, and the nozzle 103 sprays water droplets onto the outer surface of the evaporator.

[0092] In this way, water droplets adhere to the outer surface of the evaporator and gradually frost. After the refrigeration system of the air conditioner is turned off, the temperature of the evaporator gradually rises, and the frost on the outer surface of the evaporator gradually melts to form liquid water. The liquid water flows along the outer surface of the evaporator under the action of gravity or airflow, and flushes and cleans the outer surface of the evaporator. Compared with the prior art that only relies on water vapor in the air to form frost on the evaporator, it can accelerate frosting and increase the thickness of frost. After defrosting, the liquid water has greater kinetic energy and has a stronger flushing effect on the outer surface of the evaporator, thereby achieving an enhanced frost and decontamination effect.

[0093] Among them, in the second embodiment, if Figure 2b As shown, the following steps are also included:

[0094] A21: a liquid detergent is placed in one of the liquid storage spaces of the liquid storage device 203;

[0095] A31: After the air conditioner is turned on for cooling, the injection system is controlled to start, the valve 202 is opened, the liquid pump 201 is started, and the nozzle 103 sprays water droplets and detergent droplets onto the outer surface of the evaporator.

[0096] In this way, when working, water droplets and detergent droplets are sprayed onto the outer surface of the evaporator. The water droplets are defrosted to flush and clean the outer surface of the evaporator. At the same time, the detergent is dissolved in the water formed by defrosting. The detergent dissolves the dirt on the surface of the evaporator and kills the bacteria on the outer surface of the evaporator, thereby enhancing the cleaning ability.

[0097] Wherein, in the second embodiment, the following steps are also included:

[0098] B1: After the air conditioner is turned on for cooling, the injection system is controlled to start after the precooling time has passed; in this way, after the air conditioner is turned on for cooling, the evaporator needs to go through a precooling time (the time it takes for the evaporator to cool to the point where the water vapor in contact with its outer surface can frost). When the evaporator is cooled to the point where the water vapor in contact with its outer surface can frost, water droplets are sprayed onto the surface of the evaporator, which can reduce water consumption and prevent the water sprayed on the surface of the evaporator from dripping down without frosting in time.

[0099] In the second embodiment, the valve 202 is a solenoid valve, and the method for controlling the injection system includes:

[0100] The main circuit of the solenoid valve and the main circuit of the liquid pump 201 are electrically connected to the switch control unit of the refrigeration system of the air conditioner respectively.

[0101] In this way, after the air conditioner starts cooling, the main circuit of the solenoid valve and the main circuit of the liquid pump 201 start to be energized, and can respond in time and perform the injection work responsively without the need to install additional sensors or detection units, thereby reducing the cost of the evaporator purification device of the air conditioner; or, the injection system includes a control main board, the valve 202 includes a solenoid valve, the liquid pump 201 and the solenoid valve are electrically connected to the control main board respectively, and the control main board is communicatively connected to the main board of the air conditioner; in this way, after the air conditioner starts cooling, the main board of the air conditioner sends a control instruction to the control main board of the evaporator purification device of the air conditioner, directly controlling the evaporator purification device of the air conditioner to perform the injection work.

[0102] Figure 3a It is a schematic diagram of the process of producing aromatic fresh air in the third embodiment of the present invention.

[0103] A third embodiment of the present invention provides a method for producing fragrant fresh air, such as Figure 3a As shown, an evaporator purification device for an air conditioner using any one of the first embodiments of the present invention is used, wherein the liquid storage device 203 includes at least two liquid storage spaces, and the liquid storage spaces are respectively connected to the liquid inlet of the liquid pump 201 through the liquid inlet pipe 204; and the following steps are included:

[0104] C1: Install the plate 101 between the filter and the middle frame grille of the air conditioner;

[0105] C2: A fragrance is placed in one of the liquid storage spaces of the liquid storage device 203;

[0106] C3: After the air conditioner is turned on for cooling, the injection system is controlled to start, the valve 202 is opened, the liquid pump 201 is started, and the nozzle 103 sprays the fragrance onto the outer surface of the evaporator and / or the fresh air.

[0107] In this way, the refrigerant is sprayed on the outer surface of the evaporator or in the fresh air, gradually mixed into the fresh air and blown into the room, giving the fresh air a fragrant smell.

[0108] Figure 4a It is a schematic flow chart of a method for frosting, decontamination and producing fragrant fresh air in a fourth embodiment of the present invention.

[0109] A fourth embodiment of the present invention provides a method for frosting, removing dirt and producing fragrant fresh air, such as Figure 4a As shown, an evaporator purification device for an air conditioner using any one of the first embodiments of the present invention is used, wherein the liquid storage device 203 includes at least two liquid storage spaces, and the liquid storage spaces are respectively connected to the liquid inlet of the liquid pump 201 through the liquid inlet pipe 204; and the following steps are included:

[0110] D1: The plate 101 is installed between the filter screen and the middle frame grille of the air conditioner, and the side of the plate 101 provided with the nozzle 103 faces the evaporator;

[0111] D2: The liquid storage space of the liquid storage device 203 contains liquid water, liquid detergent and fragrance respectively;

[0112] D3: After the air conditioner is turned on for cooling, the injection system is controlled to start, the valve 202 is opened, the liquid pump 201 is started, and the nozzle 103 sprays water droplets and detergent droplets onto the outer surface of the evaporator. The nozzle 103 sprays fragrance onto the outer surface of the evaporator and / or into the fresh air.

[0113] In this way, water droplets adhere to the outer surface of the evaporator and gradually frost. After the refrigeration system of the air conditioner is turned off, the temperature of the evaporator gradually rises, and the frost on the outer surface of the evaporator gradually melts to form liquid water. The liquid water flows along the outer surface of the evaporator under the action of gravity or air flow, and flushes and cleans the outer surface of the evaporator. Compared with the prior art that only relies on water vapor in the air to frost on the evaporator, it can accelerate frosting and increase the thickness of frost. After defrosting, the kinetic energy of liquid water is greater, and the flushing effect on the outer surface of the evaporator is stronger, thereby achieving the effect of enhancing frost and removing dirt. At the same time, the water formed by defrosting contains decontamination agents The decontaminant and detergent dissolve the dirt on the surface of the evaporator and kill the bacteria on the outer surface of the evaporator, thereby enhancing the cleaning ability and achieving a sterilization effect; at the same time, the fragrance is sprayed onto the surface of the evaporator or into the fresh air, which can not only enhance the frosting and decontamination effect, but also make the fresh air blown into the room have a fragrant smell, making the fresh air blown into the room fresher and cleaner; by controlling the opening or closing of each valve 202 and the corresponding liquid pump 201, different spray function combinations can be switched, for example: spraying water, spraying decontaminant, spraying fragrance, spraying water and decontaminant, spraying water and fragrance, spraying decontaminant and fragrance.
