[0031] Next, the present invention will be specifically described by way of exemplary embodiments. However, it should be understood that, without further narration, the elements, structures, and features in one embodiment can also be beneficially combined into other embodiments. In this application, the kitchen air conditioner performs the refrigeration cycle by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, throttling, and evaporation, and supplies cold or heat to the air that has been conditioned and heat-exchanged. The compressor compresses the refrigerant gas in a low-temperature and low-pressure state and discharges the 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 the heat is released to the surrounding environment through the condensation process. The expansion valve throttles the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure gas-liquid two-phase refrigerant.

[0032] In the evaporator, after the refrigerant expanded in the expansion valve absorbs heat and evaporates, it is in a low-temperature and low-pressure state. Subsequently, the refrigerant gas returns to the compressor. The evaporator can achieve the refrigeration effect by using the latent heat of vaporization of the refrigerant to perform heat exchange with the material to be cooled.

[0033] The air conditioner includes an indoor unit and an outdoor unit. The indoor unit includes a body. Throughout the cycle, the air conditioner can adjust the temperature of the indoor space. The outdoor unit of a wall-mounted air conditioner refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of a wall-mounted air conditioner includes an indoor heat exchanger, and the expansion valve can be provided in the indoor unit or the outdoor unit. The indoor heat exchanger and the outdoor heat exchanger can be used as a condenser or an evaporator respectively. When the indoor heat exchanger is used as a condenser, the air conditioner serves as a heater in the heating mode. When the indoor heat exchanger is used as an evaporator, the indoor unit serves as a cooler in the cooling mode.

The refrigerant is compressed by the compressor and transported to the indoor heat exchanger 300 and the outdoor heat exchanger to realize the flow of the refrigerant in the indoor heat exchanger 300 and the outdoor heat exchanger.

[0155] In some embodiments, a volute is disposed in the indoor unit 100. The volute is disposed at the front side inside the indoor unit 100, and an air-conditioning air duct communicating with the indoor air outlet is formed in the volute.

[0156] In some embodiments, the indoor heat exchanger 300 is detachably connected to the volute. The air-conditioning air duct partitions the air-conditioning air duct, and the air flow passing through the air-conditioning air duct needs to pass through the indoor heat exchanger 300 first and then be output through the indoor air outlet.

[0157] In some embodiments, the indoor heat exchanger 300 is a three-fold heat exchanger.

[0158] In some embodiments, a reversing valve is disposed on the refrigerant flow paths of the indoor heat exchanger 300, the outdoor heat exchanger, and the compressor. The flow direction of the refrigerant is changed by the reversing valve to control whether the indoor heat exchanger 300 is used as an evaporator or a condenser, so as to change the cooling mode or the heating mode.

[0159] In some embodiments, the reversing valve is an electromagnetic valve, which is electrically connected to the electronic control board. The switching between the cooling mode and the heating mode can be realized through the electronic control board.

[0160] In some embodiments, a wind deflector 180 is disposed at the indoor air outlet, and the wind direction of the air flow blowing into the room through the indoor air outlet is adjusted by the flipping of the wind deflector 180.

[0161] In some embodiments, the length direction of the indoor air outlet is the same as the length direction of the indoor unit 100. The length direction of the wind deflector 180 is the same as the length direction of the indoor air outlet.

[0162] In some embodiments, when the wind deflector 180 directs the air flow to the upper part of the room, it is in a state of preventing direct blowing.

[0163] In some embodiments, when the wind deflector 180 directs the air flow to the upper part of the room, it is in a state of preventing cold air.

[0164] In some embodiments, a third driving member is disposed at the indoor air outlet. The third driving member is used to drive the wind deflector 180 to flip. The third driving member is electrically connected to the electronic control board.

[0165] In some embodiments, the third driving member is a motor.

[0166] In some embodiments, the third driving member is a motor.

[0167] In some embodiments, the fresh air inlet and the indoor air outlet are connected through a fresh air duct; the fresh air baffle 110 is used to open or close the fresh air duct.

[0168] Please refer to all the attached drawings. In some embodiments, the kitchen air conditioner further includes a controller, which is electrically connected to the electronic control board. The control is configured as follows: after entering the first mode, control the oil fume sensor 140 to obtain the oil fume content value; if the oil fume content value is greater than the preset content value, control the fresh air baffle 110 to open the fresh air duct.

[0169] Control the indoor baffle 700 to close the indoor air return opening.

[0170] When the oil fume content value is greater than the preset content value, it means that there is a large amount of oil fume in the kitchen. By opening the fresh air duct and closing the indoor air return opening, outdoor fresh air can enter the room. And the indoor and outdoor are connected, balancing the indoor and outdoor air pressures. When the range hood is working, the indoor oil fume is discharged, and the outdoor fresh air enters the room, improving the smoke exhaust effect of the range hood and reducing the oil fume in the kitchen.

[0171] In the prior art, the kitchen air conditioner only has an indoor air return opening and an indoor air outlet. Without opening the window, the room is isolated from the outside world. When the range hood is turned on, the range hood extracts the indoor air, causing a negative pressure in the room, increasing the working pressure of the range hood, and as the indoor air pressure decreases, the air volume discharged from the kitchen by the range hood also decreases. Therefore, the smoke exhaust effect is poor.

[0172] When the window is open, the outdoor air directly enters the room through the window, and the outdoor dust will also enter the room together. Therefore, it will pollute the indoor environment and affect the user experience. And this application is provided with a first filter element 500. Therefore, when the fresh air duct is opened and the indoor air return opening is closed, the outdoor air is filtered and then enters the room. While improving the oil fume exhaust in the kitchen, it also avoids the outdoor dust from entering the room and polluting the room.

[0173] In addition, when cooking with an open flame, the flame consumes the oxygen in the air, resulting in a decrease in the oxygen content in the air. In this application, introducing outdoor fresh air into the room can supplement oxygen for the room, improve the combustion effect of the open flame, increase the cooking speed, and avoid the danger caused by excessive carbon dioxide.

[0174] In some embodiments, after entering the first mode, control the oil fume sensor 140 to obtain the oil fume content value; if the oil fume content value is greater than the preset content value, control the first driving member 900 to drive the fresh air baffle 110 to open the fresh air duct.

[0175] If the oil fume content value is greater than the preset content value, control the second driving member 130 to drive the indoor baffle 700 to close the indoor air return opening.

[0176] In some embodiments, the oil fume sensor 140 can also detect the carbon monoxide content in the room. When the carbon monoxide content is greater than the preset content value, control the first driving member 900 to drive the fresh air baffle 110 to open the fresh air duct. Control the second driving member 130 to drive the indoor baffle 700 to close the indoor air return opening. So that outdoor fresh air enters the room, increases the oxygen content in the room, discharges carbon monoxide, and avoids the occurrence of carbon monoxide poisoning.

[0177] In some embodiments, control the oil fume sensor 140 to obtain the oil fume content value as the PM2.5 value, and the preset content value is the PM value of 10 μg / m³. When the PM value is greater than 10 μg / m³, the harm to the human body increases.

[0178] In some embodiments, if the oil fume content value is less than the preset content value, the kitchen air conditioner operates according to the previous state. The first mode is the active oil fume removal mode. If the oil fume is large, the fresh air mode is turned on to remove the oil fume. If the oil fume is small, no oil fume removal is performed.

[0179] In some embodiments, after entering the first mode, control the oil fume sensor 140 to obtain the oil fume content value. Determine whether the oil fume content value is greater than the preset content value. If so, control the first driving member 900 to drive the fresh air baffle 110 to open the fresh air duct; control the second driving member 130 to drive the indoor baffle 700 to close the indoor air return opening. If not, control the kitchen air conditioner to operate according to the previous state.

[0180] In some embodiments, if the oil fume content value is greater than the preset content value, control the outdoor temperature sensor 160 to obtain the outdoor temperature value. If the outdoor temperature value is not less than the first preset temperature value, control the fresh air baffle 110 to open the fresh air duct, control the indoor baffle 700 to close the indoor air return opening, and control the indoor heat exchanger 300 to be used as an evaporator. The outdoor temperature is relatively high. If outdoor air directly enters the room, it will cause the indoor temperature to be relatively high and unable to achieve a cooling effect. Therefore, the outdoor fresh air is cooled by the indoor heat exchanger 300 and then input into the room to cool the room while removing the oil fume.

[0181] In some embodiments, the specific steps of controlling the indoor heat exchanger 300 to be used as an evaporator are to control the reversing valve to change the flow path of the refrigerant so that the indoor heat exchanger 300 is used as an evaporator.

[0182] In some embodiments, the process of determining whether the outdoor temperature value is less than the first preset temperature value is after controlling the first driving member 900 to drive the fresh air baffle 110 to open the fresh air duct.

[0183] In some embodiments, the process of determining whether the outdoor temperature value is less than the first preset temperature value is after controlling the second driving member 130 to drive the indoor baffle 700 to close the indoor air return opening.

[0184] In some embodiments, after controlling the outdoor temperature sensor 160 to obtain the outdoor temperature value, if the outdoor temperature value is less than the first preset temperature value, then the relationship between the outdoor temperature value and the second preset temperature value is determined. If the outdoor temperature value is not less than the second preset temperature value, then the compressor is controlled to shut down.

[0185] It should be noted that the second preset temperature value is less than the first preset temperature value. If the outdoor temperature value is between the first preset temperature value and the second preset temperature value, it means that the current outdoor temperature is appropriate, and the indoor can be directly cooled by the outdoor fresh air.

[0186] In some embodiments, in determining the relationship between the outdoor temperature value and the second preset temperature value, if the outdoor temperature value is less than the second preset temperature value, then the compressor is shut down, and the air deflector 180 is controlled to move to the cold air prevention state. The outdoor temperature value being less than the second preset temperature value means that the outdoor temperature is relatively low, and cold air directly blowing into the room is likely to cause discomfort to the user. Therefore, the air deflector 180 moves to prevent cold air to avoid user discomfort.

[0187] In some embodiments, when the air deflector 180 is in the cold air prevention state and the air deflector 180 guides the air flow output from the indoor air outlet to the upper part of the room. In this state, the outdoor fresh air blows towards the top of the room and does not directly blow towards the user, improving user comfort. And because the temperature of the outdoor fresh air is relatively low, the cold air is blown towards the upper part of the room. Since cold air descends and hot air rises, the cold air gradually descends at the top of the kitchen for overall cooling, improving the cooling effect.

[0188] In some embodiments, if the outdoor temperature value is less than the second preset temperature value, then the compressor is shut down, and the third driving member is started to make the air deflector 180 move to the cold air prevention state.

[0189] In some embodiments, if the oil fume content value is greater than the preset content value, the outdoor temperature sensor 160 is controlled to obtain the outdoor temperature value. Whether the outdoor temperature value is not less than the first preset temperature value. If so, the first driving member 900 is controlled to drive the fresh air baffle 110 to open the fresh air duct; the second driving member 130 is controlled to drive the indoor baffle 700 to close the indoor air return opening, and the indoor heat exchanger 300 is controlled to be used as an evaporator. If not, then it is determined whether the outdoor temperature value is not less than the second preset temperature value. If so, the compressor is controlled to shut down. If not, the compressor is controlled to shut down, and the air deflector 180 is controlled to move to the cold air prevention state.

[0190] In some embodiments, when determining the relationship between the outdoor temperature value and the second preset temperature value, if the outdoor temperature value is less than the second preset temperature value, the reversing valve is controlled so that the indoor heat exchanger 300 is used as a condenser. The fresh air entering the room is heated by the indoor heat exchanger 300 to prevent discomfort to the user caused by the too low temperature of the fresh air.

[0191] In some embodiments, in the first mode, the first preset temperature value is any value between -70°C and 70°C. The first preset temperature value is the factory preset.

[0192] In some embodiments, the first preset temperature value is set by the user.

[0193] In some embodiments, the first preset temperature value is sent from the cloud.

[0194] In some embodiments, in the second mode, the first preset temperature value is any value between -70°C and 70°C. The first preset temperature value is the factory preset.

[0195] In some embodiments, the second preset temperature value is set by the user.

[0196] In some embodiments, the second preset temperature value is sent from the cloud.

[0197] In some embodiments, in the first mode, the first preset temperature value is 25°C. The second preset temperature value is 10°C.

[0198] In some embodiments, the controller is configured to: after entering the second mode, control the outdoor temperature sensor 160 to obtain the outdoor temperature value. If the outdoor temperature value is not less than the third preset temperature value, control the fresh air baffle 110 to close the fresh air duct; control the indoor baffle 700 to open the indoor air return opening; control the indoor heat exchanger 300 to be used as an evaporator.

[0199] In the above solution, if the outdoor temperature value is not less than the third preset temperature value, it means that the outdoor temperature is relatively high. Therefore, only the indoor air circulation is performed, and the air is cooled by the indoor heat exchanger 300 and then output to the room to achieve cooling.

[0200] In some embodiments, the second mode is an energy-saving mode.

[0201] In some embodiments, the controller is configured to: in the second mode, if the outdoor temperature value is less than the third preset temperature value, determine the relationship between the outdoor temperature value and the fourth preset temperature value. If the outdoor temperature value is less than the fourth preset temperature value, turn off the compressor and control the fresh air baffle 110 to open the fresh air duct.

[0202] Through the above solution, the outdoor temperature is just right, and the outdoor fresh air can be directly introduced into the room to cool the room. There is no need for the compressor to work, saving energy.

[0203] In some embodiments, the specific operation of controlling the fresh air baffle 110 to open the fresh air duct is to control the first driving member 900 to drive the fresh air baffle 110 to flip so as to open the fresh air duct.

[0204] In some embodiments, the controller is configured to: in the second mode, if the outdoor temperature value is not less than the fourth preset temperature value, control the indoor temperature sensor 150 to obtain the indoor temperature value, and judge the relationship between the indoor temperature value and the fifth preset temperature value. If the indoor temperature value is not less than the fifth preset temperature value, control the indoor heat exchanger 300 to be used as an evaporator, control the fresh air baffle 110 to open the fresh air duct, control the indoor baffle 700 to close the indoor air return opening. After running for a preset time, control the fresh air baffle 110 to close the fresh air duct, and control the indoor baffle 700 to open the indoor air return opening.

[0205] Through the above solution, the indoor air is first preliminarily cooled by the outdoor fresh air with a lower outdoor temperature, and then the indoor air is circulated to cool the indoor air, reducing the load on the compressor and saving energy.

[0206] In some embodiments, the fifth preset temperature value is the outdoor temperature value plus a preset increment value.

[0207] In some embodiments, the preset increment value is a factory preset.

[0208] In some embodiments, the preset increment value is user - set.

[0209] In some embodiments, the preset increment value is sent from the cloud.

[0210] In some embodiments, the preset increment value is 5°C.

[0211] In some embodiments, the preset time is a factory preset. In some embodiments, the preset time is user - set.

[0212] In some embodiments, the preset time is sent from the cloud.

[0213] In some embodiments, the preset time is 5 minutes.

[0214] In some embodiments, in the second mode, when judging the relationship between the indoor temperature value and the fifth preset temperature value, if the indoor temperature value is less than the fifth preset temperature value, control the indoor heat exchanger 300 to be used as an evaporator, control the fresh air baffle 110 to close the fresh air duct, and control the indoor baffle 700 to open the indoor air return opening.

[0215] In the above solution, if the indoor temperature value is less than the fifth preset temperature value, it means that the temperature of the outdoor fresh air is not suitable for input into the room, avoiding the increase in the cooling burden of the kitchen air conditioner caused by the entry of outdoor fresh air into the room, thereby reducing the working duration and burden of the compressor and saving energy.

[0216] In some embodiments, in the second mode, the specific operation of controlling the indoor heat exchanger 300 to be used as an evaporator is as follows: if the current compressor is not turned on, turn on the compressor. If the current indoor heat exchanger 300 is used as a condenser, control the reversing valve to change the flow direction of the refrigerant.

[0217] In some embodiments, in the second mode, the specific operation of controlling the fresh air baffle 110 to open the fresh air duct is as follows: control the first driving member 900 to drive the fresh air baffle 110 to flip to open the fresh air duct.

[0218] In some embodiments, in the second mode, the specific operation of controlling the fresh air baffle 110 to close the fresh air duct is as follows: control the first driving member 900 to drive the fresh air baffle 110 to flip so that the fresh air baffle 110 closes the fresh air duct.

[0219] In some embodiments, in the second mode, the specific operation of controlling the indoor baffle 700 to open the indoor return air opening is as follows: control the second driving member 130 to drive the indoor baffle 700 to flip to open the indoor return air opening.

[0220] In some embodiments, in the second mode, the specific operation of controlling the indoor baffle 700 to close the indoor return air opening is as follows: control the second driving member 130 to drive the indoor baffle 700 to flip to close the indoor return air opening.

[0221] In some embodiments, in the second mode, the third preset temperature value is any value between -70°C and 70°C. The third preset temperature value is the factory preset.

[0228] In some embodiments, in the second mode, the fourth preset temperature value is 10 °C.

Determine whether the outdoor temperature value is not less than the third preset temperature value; If so, control the fresh air damper 110 to close the fresh air duct; control the indoor damper 700 to open the indoor return air opening; control the indoor heat exchanger 300 to be used as an evaporator.

[0232] If not, control the indoor heat exchanger 300 to be used as an evaporator. Control the fresh air damper 110 to close the fresh air duct. Control the indoor damper 700 to open the indoor return air opening.

[0233] In some embodiments, the first mode and the second mode can run alternately or synchronously.

[0234] In some embodiments, the priority of the first mode is higher than that of the second mode.

[0235] In some embodiments, the priority of the second mode is higher than that of the first mode.

[0236] In some embodiments, the controller is preset with the first mode and the second mode.

[0237] In some embodiments, the control is configured to: if the gesture control sensor 170 detects that the user's gesture waves in the first direction for the first preset number of times, and the interval time between the gestures detected by the gesture control sensor 170 is greater than the set time, then control the speed of the indoor fan 400 to increase by one gear.

[0238] In some embodiments, the first direction is any one of the two directions of the length of the indoor unit 100. The user can wave horizontally, which is convenient for the user to operate.

[0239] In some embodiments, the first direction is the horizontal direction.

[0240] In some embodiments, the control is configured such that if the gesture control sensor 170 detects that the user's gesture swings in the first direction more than a first preset number of times, and the interval time between the gestures detected by the gesture control sensor 170 is greater than a set time, then the control continuously increases the rotational speed of the indoor blower 400 until the highest gear.

[0241] For example, assume that the set time is 1, the first preset number of times is 3, the gesture control sensor 170 detects that the user's gesture swings in the first direction 4 times, and the interval time between each detected swing of the user's gesture in the first direction is greater than the set time. Then, the first 3 times reach the first preset number of times, the control increases the rotational speed of the indoor blower 400 by one gear, and for the detected extra 4 - 3 = 1 time, the rotational speed of the indoor blower 400 is continuously increased.

[0242] In some embodiments, the first preset number of times can be any value, and the first preset number of times is the factory preset.

[0243] In some embodiments, the first preset number of times is sent from the cloud.

[0244] In some embodiments, the first preset number of times is set by the user.

[0245] In some embodiments, the first preset number of times is 1 time.

[0246] In some embodiments, the control is configured such that if the gesture control sensor 170 detects that the user's gesture swings in the first direction more than a first preset number of times, and the interval time between the gestures detected by the gesture control sensor 170 is greater than a set time, then the control directly increases the rotational speed of the indoor blower 400 to the highest gear.

[0247] For example, the first preset number of times is 1. The gesture control sensor 170 detects that the user's gesture swings in the first direction 3 times. Then, the control directly operates the indoor blower 400 at the highest gear.

[0248] In some embodiments, the control is configured such that if the gesture control sensor 170 detects that the user's gesture swings in the first direction more than a first preset number of times, and the interval time between the gestures detected by the gesture control sensor 170 is greater than a set time, then each time the user's gesture swings in the first direction more than the first preset number of times is detected, the rotational speed of the indoor blower 400 is increased by one gear.

[0249] For example, the indoor fan 400 has 6 speed settings, the first preset number of times is 2, and the current speed setting of the indoor fan 400 is 2. The gesture control sensor 170 detects that the user's gesture waves 4 times in the first direction, and the interval time between the waves detected by the gesture control sensor 170 is greater than the set time. When the first preset number of times is reached, the speed of the indoor fan 400 is increased by 1 gear. The total number of waves minus the first preset number of times is the number of additional times needed to increase the gear of the indoor fan 400, that is, 4 - 2 = 2 times. Therefore, it is necessary to increase 3 gears on the basis of the current speed setting of the indoor fan 400, that is, 2 + 1 + 2 = 5 gears.

[0250] In some embodiments, the control is configured such that: if the gesture control sensor 170 detects that the user's gesture waves in the second direction for a second preset number of times and the interval time between consecutive waves is less than the set time, then the frequency of the compressor is controlled to increase.

[0251] In some embodiments, the control is configured such that: if the gesture control sensor 170 detects that the user's gesture continuously waves in the second direction for a second preset number of times and the interval between consecutive waves is less than the set time, then the frequency of the compressor is controlled to increase by one gear.

[0252] In some embodiments, the set time can be any value, which can be preset at the factory.

[0253] In some embodiments, the set time is sent from the cloud.

[0254] In some embodiments, the set time is set by the user.

[0255] In some embodiments, the set time is 1 second.

[0256] In some embodiments, the set time is 2 seconds.

[0257] In some embodiments, the second preset number of times can be any value, and the second preset number of times is preset at the factory.

[0258] In some embodiments, the second preset number of times is sent from the cloud.

[0259] In some embodiments, the second preset number of times is set by the user.

[0260] In some embodiments, the second preset number of times is 2 times.

[0261] In some embodiments, the control is configured such that: if the gesture control sensor 170 detects that the user's gesture continuously waves in the second direction more than the second preset number of times and the interval between the waves of the user's gesture is within the set time. Then the frequency of the compressor is controlled to increase until the maximum.

[0262] In some embodiments, the control is configured such that if the gesture control sensor 170 detects that the user gesture continuously waves in the second direction more than a second preset number of times and the intervals between the waves of the user gesture are within a set time, then the frequency of the compressor is directly increased to the maximum.

[0263] For example, within the set time, if the second preset number of times is 2 times, and the user waves 3 times or more within the set time, then the compressor is controlled to operate at the maximum frequency.

[0264] In some embodiments, the control is configured such that if the gesture control sensor 170 detects that the user gesture continuously waves in the second direction more than a second preset number of times and the intervals between the waves of the user gesture are within a set time, then each time the user gesture is detected to wave in the second direction more than the second preset number of times, the frequency of the compressor is increased by one gear.

[0265] For example, the compressor has 5 gears, the second preset number of times is 2, and the current frequency gear of the compressor is 1. The gesture control sensor 170 detects that the user gesture waves 3 times in the second direction within the set time. Then, on the basis of the current indoor fan 400 gear, 3 gears are increased, that is, 1 + 2 = 3 gears.

[0266] In some embodiments, to avoid control confusion, if the first direction is the same as the second direction, then the first preset number of times is different from the second preset number of times.

[0267] In some embodiments, to avoid control confusion, if the first preset number of times is the same as the second preset number of times, then the first direction is different from the second direction.

[0268] In some embodiments, the control is configured such that if the gesture control sensor 170 detects that the user gesture waves in the third direction a third preset number of times, then the rotation speed of the indoor fan 400 is reduced by one gear.

[0269] In some embodiments, the third direction is any one of the two directions of the length of the indoor unit 100. The user can wave horizontally, which is convenient for the user to operate.

[0270] In some embodiments, the third direction is the horizontal direction.

[0271] In some embodiments, the control is configured such that if the gesture control sensor 170 detects that the user gesture waves in the third direction more than the third preset number of times and the gesture control sensor 170 detects that the interval time of the user's wave is greater than the set time, then the rotation speed of the indoor fan 400 is continuously reduced until the lowest gear.

[0272] In some embodiments, the third preset number of times can be any value, and the third preset number of times is the factory preset.

[0273] In some embodiments, the third preset number of times is sent by the cloud.

[0274] In some embodiments, the third preset number of times is set by the user.

[0275] In some embodiments, the third preset number of times is 1 time.

[0276] In some embodiments, the control is configured such that: if the gesture control sensor 170 detects that the user's gesture waves in the third direction more than the third preset number of times, and the interval time between the waves of the user's gesture detected by the gesture control sensor 170 is greater than the set time. Then the rotation speed of the indoor fan 400 is directly reduced to the lowest gear.

[0277] For example, the third preset number of times is 1. The gesture control sensor 170 detects that the user's gesture waves in the third direction 3 times. Then the indoor fan 400 is directly controlled to operate at the lowest gear.

[0278] In some embodiments, the control is configured such that: if the gesture control sensor 170 detects that the user's gesture waves in the third direction more than the third preset number of times, and the interval time between the waves of the user's gesture detected by the gesture control sensor 170 is greater than the set time. Then each time the user's gesture is detected to wave in the third direction more than the third preset number of times, the rotation speed of the indoor fan 400 is reduced by one gear.

[0279] For example, the indoor fan 400 has 6 gears, the first preset number of times is 2, and the current gear of the indoor fan 400 is 5. The gesture control sensor 170 detects that the user's gesture waves in the first direction 4 times, and the interval time between the waves of the user's gesture detected by the gesture control sensor 170 is greater than the set time. Reaching the first preset number of times, the rotation speed of the indoor fan 400 is reduced by 1 gear, and the total number of waves minus the first preset number of times is the number of additional times required to downshift the indoor fan 400, that is, 4 - 2 = 2 times. Therefore, it is necessary to increase or decrease 3 gears based on the current gear of the indoor fan 400, that is, 5 - 2 - 1 = 2 gears.

[0280] In some embodiments, the control is configured such that: if the gesture control sensor 170 detects that the user's gesture continuously waves in the fourth direction for the fourth preset number of times, and the interval between the waves of the user's gesture is within the set time. Then the frequency of the compressor is controlled to decrease.

[0281] In some embodiments, the control is configured such that: if the gesture control sensor 170 detects that the user's gesture continuously waves in the fourth direction for the fourth preset number of times within the set time, then the frequency of the compressor is controlled to decrease by one gear.

[0282] In some embodiments, the fourth preset number of times can be any value, and the fourth preset number of times is the factory preset.

[0283] In some embodiments, the fourth preset number of times is sent by the cloud.

[0284] In some embodiments, the fourth preset number of times is set by the user.

[0285] In some embodiments, the fourth preset number of times is 2 times.

[0286] In some embodiments, the control is configured such that if the gesture control sensor 170 detects that the user gesture waves continuously in the fourth direction for more than the fourth preset number of times and the intervals between the waves of the user gesture are within the set time, then the frequency of the compressor is controlled to decrease until it is turned off.

[0287] For example, the compressor has 5 gears, the fourth preset number of times is 2, and the current frequency gear of the compressor is 4. The gesture control sensor 170 detects that the user gesture waves 6 times in the fourth direction. The intervals between the waves of the user gesture are within the set time. When the fourth preset number of times is reached, the frequency of the compressor is decreased by 1 gear. The total number of waves minus the fourth preset number of times is the additional number of times needed to further decrease the gear of the compressor frequency, that is, 6 - 2 = 4. Therefore, based on the current gear of the compressor frequency, subtract 4 - 1 - 4 = -1 gear. Since the lowest gear of the compressor frequency is only 1 gear, when it is decreased to 1 gear and then further decreased, the compressor is directly turned off.

[0288] In some embodiments, the control is configured such that if the gesture control sensor 170 detects that the user gesture waves continuously in the fourth direction for more than the fourth preset number of times and the intervals between the waves of the user gesture are within the set time, then the frequency of the compressor is controlled to decrease until the lowest frequency.

[0289] In some embodiments, the control is configured such that if the gesture control sensor 170 detects that the user gesture waves continuously in the fourth direction for more than the fourth preset number of times and the intervals between the waves of the user gesture are within the set time, then the frequency of the compressor is directly controlled to decrease to the lowest frequency.

[0290] For example, if the fourth preset number of times is 2 times, and the user waves 3 times or more in the fourth direction and the intervals between the waves of the user gesture are within the set time, then the compressor is controlled to operate at the lowest frequency.

[0291] In some embodiments, the control is configured such that if the gesture control sensor 170 detects that the user gesture waves continuously in the fourth direction for more than the fourth preset number of times within the set time, then each time the user gesture is detected to wave in the fourth direction for more than the fourth preset number of times, the frequency of the compressor is decreased by one gear.

[0292] For example, the compressor has 5 speed settings, the fourth preset number of times is 2, and the current frequency setting of the compressor is 4. The gesture control sensor 170 detects that the user's gesture waves 4 times in the fourth direction. The intervals between the waves of the user's gesture are within the set time. When the fourth preset number of times is reached, the frequency of the compressor is reduced by 1 gear. The total number of waves minus the fourth preset number of times is the number of additional times required to further downshift the compressor frequency, that is, 4 - 2 = 2. Therefore, based on the current frequency setting of the compressor, subtract 3 gears, that is, 4 - 1 - 2 = 1 gear.

[0293] In some embodiments, for the convenience of user memory and operation, the third direction is the reverse of the first direction.

[0294] In some embodiments, the fourth direction is the reverse of the second direction.

[0295] In some embodiments, to avoid control confusion, if the third direction is the same as the fourth direction, the third preset number of times is different from the fourth preset number of times.

[0296] In some embodiments, to avoid control confusion, if the third preset number of times is the same as the fourth preset number of times, the third direction is different from the fourth direction.

[0297] In some embodiments, after the gesture control sensor 170 detects the first gesture, it is recorded as 1 time and starts recording the time, and records whether there is a gesture wave within the set time, and records the direction of the gesture wave, and performs corresponding control.

Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
