In this application, an air conditioner performs a refrigeration cycle of an air conditioner indoor unit by using a compressor, a condenser, an expansion valve, and an indoor heat exchanger. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a refrigerant to the air that has been conditioned and heat exchanged. The compressor compresses refrigerant gas in a low-temperature and low-pressure state and discharges refrigerant gas in a high-temperature and high-pressure state. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process. The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The indoor heat exchanger evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low temperature and low pressure state to the compressor. The indoor heat exchanger may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of vaporization of a refrigerant. Throughout the cycle, the air conditioner may adjust the temperature of the indoor space. An outdoor unit of an air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, an 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. The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an indoor heat exchanger. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater of a heating mode, and when the indoor heat exchanger is used as an indoor heat exchanger, the air conditioner is used as a cooler of a cooling mode.

Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 6, in an exemplary embodiment of the air conditioner of the present invention, the air conditioner includes: the air conditioner comprises a shell, an air conditioner fan, an indoor heat exchanger, a liquid supply box 100, a base 200, an electric heater 300, a liquid supplementing piece 400, an oxygen supply switch 500, an oxygen concentration sensor and a controller, wherein the shell is provided with an air duct and an air conditioner air outlet communicated with the air duct; the air conditioner fan is arranged in the air duct and is used for conveying air-conditioning air into the room through an air outlet of the air conditioner; the indoor heat exchanger is arranged in the indoor unit, and heat exchange is carried out between the refrigerant flowing in the indoor heat exchanger and the air to form a heating cycle or a refrigerating cycle; under the action of the air conditioner fan, air flows are heated or cooled through the indoor heat exchanger to form air conditioner wind which enters the room through the air outlet of the air conditioner. The liquid supply tank 100 is for containing a hydrogen peroxide solution; the base 200 is provided with a closed cavity 201; the electric heater 300 is arranged in the closed cavity 201; the liquid replenishing piece 400 is used for supplying the hydrogen peroxide solution in the liquid supply tank 100 into the closed cavity 201; the oxygen supply switch 500 is used for communicating or isolating the air duct with the closed cavity 201; the oxygen concentration sensor is arranged on the shell and is used for detecting the indoor oxygen concentration.

Referring to fig. 7 and 8, the controller is configured to: when the oxygen supply mode is entered, the current indoor oxygen concentration is obtained through the oxygen concentration sensor, if the current indoor oxygen concentration is judged to be lower than a first preset oxygen concentration value, the liquid supplementing piece 400 is controlled to supply hydrogen peroxide solution into the closed cavity 201, the electric heater 300 is started, and the oxygen supply switch 500 is started to enable the closed cavity 201 to be communicated with the air duct.

Through the above technical scheme, after entering the oxygen supply mode, hydrogen peroxide in the liquid supply tank 100 is supplied into the closed cavity 201 through the liquid supplementing piece 400, the electric heater 300 heats the hydrogen peroxide to generate oxygen, and the oxygen enters the air duct and is blown into a room through the air conditioner fan, so that oxygen supply to the room is completed.

In some embodiments, the oxygen concentration sensor detects the indoor oxygen concentration every fixed time when the air conditioner is operating or standby. If the current oxygen concentration is lower than the first preset oxygen concentration value, the liquid replenishing piece 400 is controlled to supply the hydrogen peroxide solution into the closed cavity 201, the electric heater 300 is started, and the oxygen supply switch 500 is started so as to enable the closed cavity 201 to be communicated with the air duct.

In some embodiments, the first preset oxygen concentration value is a lower limit value of the comfortable oxygen concentration of the human body, and a lower value than the first preset oxygen concentration value indicates that the indoor oxygen content is insufficient. The electric heater 300 heats the hydrogen peroxide solution entering the closed chamber 201 to generate oxygen.

In some embodiments, the first preset oxygen concentration value is preset into the controller at the time of shipment. When the oxygen supply mode is entered, the first preset oxygen concentration value is directly invoked. In some embodiments, the corresponding oxygen concentrations are different because the altitude at which the user is located is different, and thus the oxygen concentrations to which the user is adapted are also different. The first preset oxygen concentration value is thus set by the user himself. The shell is provided with a control panel, and a user can adjust the value of the first preset oxygen concentration value through the control panel according to the altitude of the user.

In some embodiments, the air conditioner is a stand air conditioner, and the liquid supply tank 100 and the base 200 are disposed at the bottom end of the housing. After entering the oxygen supply mode, the oxygen supply switch 500 communicates the air duct with the closed chamber 201, hydrogen peroxide is supplied into the closed chamber 201 by the liquid replenishing member 400, so that the closed chamber 201 is filled with hydrogen peroxide, and the electric heater 300 is placed in the hydrogen peroxide solution. The control fluid replacement member 400 cuts off the fluid supply tank 100 from the closed chamber 201, so that the closed chamber 201 is only in communication with the air duct. Therefore, the oxygen formed by the hydrogen peroxide heated by the electric heater 300 only enters the air duct and is input into the room through the air outlet of the air conditioner under the action of the air conditioner fan, so that oxygen supply is realized.

Referring to fig. 2 to 6, in some embodiments, the liquid supply tank 100 is disposed above the base 200, and a liquid supplementing pipe is extended below the liquid supply tank 100, and the liquid supplementing pipe is a circular pipe and is disposed vertically downward; the fluid infusion tube extends into the closed cavity 201; the fluid replacement part 400 comprises a plug 401 and a first pushing part 402; the first pushing member 402 pushes the stopper 401 to close or separate the stopper 401 from the fluid replacement pipe. The liquid supply tank 100 is disposed above the base 200, so that when the stopper 401 does not block the liquid replenishing pipe, the hydrogen peroxide solution flows into the closed cavity 201 through the liquid replenishing pipe under the action of gravity.

In some embodiments, the liquid supply tank 100 is removably connected to the base 200. When the hydrogen peroxide solution in the liquid supply tank 100 is insufficient, the liquid supply tank 100 and the base 200 can be detached, and the hydrogen peroxide solution can be injected into the liquid supply tank 100 through the liquid supplementing pipe.

In some embodiments, the hydrogen peroxide solution is preset within the fluid supply tank 100, and the fluid supply tank 100 is a replaceable disposable or limited use consumable.

In some embodiments, the plug 401 is made of rubber or resin, and has better tightness. The first pushing piece 402 is used for pushing the plug 401 to reciprocate along the length direction of the fluid infusion tube. When the oxygen supply mode is not started, the plug 401 plugs the liquid supplementing pipe. When the oxygen supply mode is started and the current indoor oxygen concentration is lower than the first preset oxygen concentration value, the first pushing member 402 drives the plug 401 to move downwards, and the hydrogen peroxide solution flows into the closed cavity 201 through the liquid supplementing pipe. When the hydrogen peroxide solution fills the closed cavity 201, the first pushing member 402 is controlled to push the plug 401 to move upwards and block the fluid filling pipe, so that the hydrogen peroxide in the fluid supply tank 100 is blocked.

In some embodiments, the top of the connection channel is disposed on the side wall of the liquid supply tank 100, so that the connection channel has a bend, and even if impurities enter the air duct and drop down, impurities can be accumulated at the bend, so as to prevent impurities from entering the closed cavity 201.

In some embodiments, oxygen supply switch 500 includes a baffle 501 and a second pusher 502; the second pusher 502 pushes the shutter 501 to close or open the opening of the closed chamber 201. The second pushing member 502 drives the baffle 501 to reciprocate along the vertical direction.

Referring to fig. 2 to 6, in some embodiments, a sealing ring is disposed at an opening of the airtight cavity 201, and the sealing ring includes rubber or resin. The baffle 501 abuts against the tight sealing ring to complete the sealing of the opening of the closed cavity 201. The sealing effect is further improved through the sealing ring.

In some embodiments, the baffle 501 is disposed above the sealing ring, and the second pushing member 502 drives the baffle 501 to descend and abut against the upper surface of the sealing ring, so as to complete the separation of the closed cavity 201 from the air duct.
