Description

Technical Field

[0001] The present invention relates to the technical field of temperature control, and in particular to an intelligent kitchen air cooling control method and device. Background Art

[0002] At present, in the field of kitchen temperature control, traditional air conditioning solutions or fan solutions are generally used to cool the kitchen environment. At that time, for traditional air conditioners, oil stains in the kitchen environment would pollute the air conditioner, thereby reducing the life of the air conditioner or increasing the difficulty of cleaning the air conditioner. If a fan is used for cooling, it only increases air circulation. Even if water atomization or ice atomization is added to the fan, the temperature can be lowered, but there are still problems with cleaning the fan. Summary of the invention

[0003] The present invention mainly solves the problem that the existing kitchen temperature control equipment may be polluted by kitchen oil, which reduces the service life and increases the difficulty of cleaning, and provides an intelligent kitchen air cooling control method and device.

[0004] The above technical problems of the present invention are mainly solved by the following technical solutions: an intelligent kitchen air cooling control method, using an air cooling device, the device includes a refrigeration unit, the air inlet end of the refrigeration unit is connected to the air inlet outer channel and the air inlet inner channel respectively through a switching unit, and the control method includes: When the device is turned on, obtain the range hood working signal. When the range hood is working, the control switching unit is connected to the external air inlet channel so that the external air is discharged through the refrigeration unit as cold air; When the range hood is not in operation, the control switching unit is connected to the air inlet inner channel so that the internal air is discharged as cold air through the refrigeration unit.

[0005] The control method of the present invention is linked to the operation of the range hood. When the working state of the kitchen range hood is identified, generally, a large amount of oil smoke is generated during cooking in the kitchen, and there is a lot of oil smoke in the air, the control switching unit is switched to the air inlet outer channel, wherein the outside is the space or environment outside the kitchen, and the outside air is allowed to flow into the kitchen after passing through the refrigeration unit, bringing cold air to the kitchen. At the same time, combined with the kitchen cooking, the range hood discharges the oil smoke and air from the kitchen to achieve air balance in the kitchen. When the non-working state of the range hood is identified, generally, the kitchen is not cooking, and there is little oil smoke in the air, the control switching unit is switched to the air inlet inner channel, wherein the inside is the space inside the kitchen, and the internal air is allowed to enter the refrigeration unit and then flow into the kitchen again, so that the kitchen air is cooled, and the inlet and outlet air are balanced at the same time. While the present invention realizes temperature control in the kitchen, it reduces the pollution of oil smoke to the air cooling device, increases the service life of the air cooling device, and reduces the difficulty of cleaning oil stains, and realizes the balance of inlet and outlet air in the kitchen, making the air pressure in the kitchen more stable.

[0006] As a preferred solution, a first valve is provided at the connection end between the switching unit and the air inlet outer channel, and a second valve is provided at the connection end between the switching unit and the air inlet inner channel. When the range hood is working, the first valve is controlled to open and the second valve is controlled to close.

[0007] The switching unit includes a port connected to the air inlet outer channel and a port connected to the air inlet inner channel. A first valve and a second valve are respectively arranged on the two ports to control the opening and closing of the channels. When the range hood is in working state, generally when cooking in the kitchen, there is oil smoke in the air, and external air is needed for cooling. The first valve is controlled to open to connect the switching unit with the air inlet outer channel, and the second valve is controlled to close to close the switching unit with the air inlet inner channel to prevent the air with oil smoke in the kitchen from entering the cooling unit.

[0008] As a preferred solution, when the range hood is not in operation, the first valve is controlled to be closed and the second valve is controlled to be opened.

[0009] When the range hood is not in operation, generally because no cooking is done in the kitchen and there is no smoke in the air, the internal air can be used for cooling. The first valve is controlled to be closed to close the switching unit and the external air inlet channel. At the same time, the second valve is controlled to be opened to connect the switching unit and the internal air inlet channel. The air in the kitchen enters the refrigeration unit and flows into the kitchen after being cooled, thereby cooling the kitchen air and achieving a balance between the inlet and outlet air.

[0010] As a preferred solution, the device includes an exhaust unit, the refrigeration unit includes a heat dissipation channel, the output end of the exhaust unit is connected to the heat dissipation channel, and the output end of the exhaust unit is provided with a third valve. When the range hood is working, the third valve is controlled to open, the exhaust unit is connected to the heat dissipation channel, and the exhaust unit is started to discharge the internal hot air to the outside through the heat dissipation channel; When the range hood is not in operation, the third valve is controlled to be closed and the exhaust unit stops working.

[0011] The exhaust unit is preferably arranged on the upper part of the range hood. When the range hood is working, the exhaust operation is performed at the same time. The third valve is opened, and the output end of the exhaust unit is connected to the heat dissipation channel, and the heat dissipation channel is connected to the outside. The exhaust unit includes a fan. The exhaust unit works to discharge a large amount of hot air gathered above the range hood during cooking to the outside, consuming less energy to solve the large amount of heat generated during cooking, and cooperates with the refrigeration unit to achieve a faster cooling effect, while also saving energy. In addition, the exhaust unit discharges part of the kitchen air to the outside, and cooperates with the air intake of the external air inlet channel to further balance the inlet and outlet of the kitchen. When the fourth valve is set, when the device is turned on, that is, the refrigeration unit is working, the fourth valve is opened, and the air passing through the radiator of the refrigeration unit is discharged from the heat dissipation channel.

[0012] As a preferred solution, the device includes an air quality sensor, which detects the internal air quality and sets an air quality threshold. When the internal air quality value is greater than the air quality threshold, the range hood is controlled to turn on, and the switching unit is controlled to connect to the external air inlet channel so that the external air is discharged as cold air through the refrigeration unit.

[0013] This solution links the air cooling device with the range hood. By setting an air quality sensor, the air quality sensor detects the air quality in the kitchen. When the air quality in the kitchen is poor, that is, when there is a lot of oil in the air, the control switches to the air inlet channel, and at the same time controls the range hood to turn on. It can control the temperature of the kitchen environment while achieving the purification function, and also prevents the oil from polluting the air cooling device. The air cooling device and the range hood are linked, and the two can communicate via Bluetooth or WiFi, or they can enter the overall smart home system together.

[0014] As a preferred solution, the heat dissipation channel is provided with a fourth valve at the upstream of the exhaust unit. When the device is turned off, obtain the range hood working signal. When the range hood is working, the third valve is controlled to be opened, the fourth valve is controlled to be closed, and the exhaust unit is controlled to be started at the same time.

[0015] In this scheme, when the air cooling device is not turned on and the range hood is working, the oil smoke is discharged to the outside through the range hood, but the hot air generated by cooking accumulates above the range hood. At this time, the hot air is discharged to the outside by turning on the exhaust unit, without turning on the refrigeration unit. At the same time, the control is based on the setting structure of the exhaust unit. The exhaust unit is connected to the heat dissipation channel. The radiator of the refrigeration unit is set in the heat dissipation channel and is located upstream of the connection of the exhaust unit. The input end of the heat dissipation channel is connected to the air inlet channel. A heat dissipation fan is also set in the heat dissipation channel. The heat dissipation fan is located between the connection of the radiator and the exhaust unit. The heat dissipation channel takes in air through the air inlet channel to take away the heat of the radiator, and then the hot air exhausted by the exhaust unit is discharged to the outside. When the device is turned off, the heat dissipation fan does not work, and the exhaust unit is started alone to close the fourth valve to close the upstream of the heat dissipation channel to prevent the hot air with oil from entering the upstream of the heat dissipation channel and causing oil pollution to the radiator, and to prevent the oily air from flowing back. When the fourth valve is provided, when the device is turned on, it is detected that the range hood is working, the fourth valve is controlled to open, the third valve is opened, the exhaust unit is operated, and the heat dissipation and exhaust together discharge the air to the outdoors.

[0016] An intelligent kitchen air cooling device comprises a refrigeration unit and a control unit, wherein the output end of the refrigeration unit is connected to an air supply channel, the input end of the refrigeration unit is respectively connected to an external air inlet channel and an internal air inlet channel through a switching unit, the refrigeration unit radiator is arranged in the heat dissipation channel, the input end of the heat dissipation channel is connected to the external air inlet channel, and the control unit controls the opening and closing of each channel according to a range hood working signal.

[0017] The refrigeration unit of the present invention is used to refrigerate the input air. The refrigeration unit can adopt a TEC refrigeration system or a conventional compressor system, preferably a TEC refrigeration system, including a semiconductor refrigeration plate, and a temperature conductor is respectively arranged on the cold surface and the hot surface of the semiconductor refrigeration plate. The temperature conductor can adopt a wing-shaped metal structure. The temperature conductors on both sides of the semiconductor refrigeration plate are respectively located in the air supply channel and the heat dissipation channel. When the semiconductor refrigeration plate is refrigerated, the temperature conductor on the cold surface cools the air passing through, and the temperature conductor on the hot surface is a heat sink, and the heat generated by the hot surface is dissipated in the heat dissipation channel. The input end of the refrigeration unit is connected to the switching unit, and the switching unit includes two input ends, which are respectively connected to the outer air inlet channel and the inner air inlet channel. The outer air inlet channel is connected to the room outside the kitchen or the external space, and the inner air inlet channel is connected to the space inside the kitchen. The switching unit opens and closes the outer air inlet channel and the inner air inlet channel. The switching unit is connected to the control unit, and the control unit controls the switching unit to realize the opening and closing control of the outer air inlet channel and the inner air inlet channel. The control unit is connected to the range hood, obtains the range hood working signal, and controls the opening and closing of each channel according to the range hood working signal. Specifically, when the device is in working state, when the control unit detects that the range hood is working, the control switching unit is controlled to connect the refrigeration unit with the external air inlet channel, so that the external air is cooled by the refrigeration unit, and the cold air is discharged into the kitchen through the air supply channel. When the control unit detects that the range hood is not working, the control switching unit is controlled to connect the refrigeration unit with the internal air inlet channel, and the air in the kitchen is drawn into the refrigeration unit for cooling, and the cold air is then discharged into the kitchen through the air supply channel. The device of the present invention takes in air from the outside when the range hood is working, and takes in air from the inside when the range hood is not working. While achieving temperature control in the kitchen, it reduces the pollution of oil smoke to the air cooling device, increases the service life of the air cooling device, and reduces the difficulty of cleaning oil stains. In addition, when the range hood is working, the oil smoke and air in the kitchen are discharged through the range hood. When the range hood is not working, the air circulates in the kitchen, achieving the balance of air inlet and outlet in the kitchen, making the air pressure in the kitchen more stable.

[0018] As a preferred solution, a first valve is provided at the connection end between the switching unit and the air inlet outer channel, and a second valve is provided at the connection end between the switching unit and the air inlet inner channel. The first valve and the second valve are respectively connected to the control unit.

[0019] In this solution, a first valve and a second valve are respectively arranged at the connection ends between the switching unit and the air inlet outer channel and the air inlet inner channel, and the control unit controls the two valves to open to control the air inlet channel at the input end of the refrigeration unit. Specifically, when the range hood is working, the first valve is opened, the air inlet outer channel is connected to the input end of the refrigeration unit, and the second valve is closed, and the air inlet inner channel is isolated from the input end of the refrigeration unit. When the range hood is not working, the first valve is closed, the air inlet outer channel is isolated from the input end of the refrigeration unit, and the second valve is opened, and the air inlet inner channel is connected to the input end of the refrigeration unit.

[0020] As a preferred solution, it also includes an exhaust unit, the output end of the exhaust unit is connected to the heat dissipation channel, the output end of the exhaust unit is provided with a third valve, and the third valve is connected to the control unit.

[0021] The device of the present invention also includes an exhaust unit, which includes an exhaust channel and an exhaust fan arranged at the air inlet of the exhaust channel, and the exhaust channel is connected to the heat dissipation channel. The air inlet of the exhaust unit is preferably installed above the range hood, so that the hot air gathered above the range hood when it is working can be more easily discharged to the outside. A third valve is arranged on the port where the exhaust air channel is connected to the heat dissipation channel, and the control unit controls the opening and closing of the third valve. A heat dissipation fan is arranged between the radiator and the exhaust unit in the heat dissipation channel. The heat dissipation fan and the refrigeration unit work at the same time. The heat dissipation fan draws air into the refrigeration unit radiator, takes away the generated heat, and discharges it to the outside through the heat dissipation channel. The specific control process of the exhaust unit is: when the working state of the range hood is detected, the third valve is opened, the exhaust channel is connected to the heat dissipation channel, and the heat dissipation fan works at this time. Under the drive of the heat dissipation fan, the hot air entering the heat dissipation channel is discharged to the outside.

[0022] As a preferred solution, a fourth valve is provided in the heat dissipation channel upstream of the exhaust unit, and the fourth valve is connected to the control unit.

[0023] The present solution further sets a fourth valve in the heat dissipation channel upstream of the exhaust unit, and the control unit controls the opening and closing of the fourth valve. The opening and closing of the heat dissipation channel upstream of the exhaust unit is controlled by controlling the fourth valve. When the refrigeration unit of the air cooling device is not working and the heat dissipation fan is not working, the heat dissipation channel upstream is isolated to prevent the hot air entering the exhaust unit from flowing back into the heat dissipation channel upstream, polluting the radiator and even polluting the air in the outer air inlet channel.

[0024] Therefore, the advantages of the present invention are: 1. Linked with the operation of the range hood, when the working state of the kitchen range hood is identified, the control switching unit is switched to the air inlet outer channel to allow the outside air to flow into the kitchen after passing through the refrigeration unit; when the range hood is identified to be in a non-working state, the control switching unit is switched to the air inlet inner channel to allow the inside air to enter the refrigeration unit and then flow into the kitchen again, thereby achieving temperature control in the kitchen and reducing the pollution of oil smoke to the air cooling device, thereby increasing the service life of the air cooling device and reducing the difficulty of cleaning oil stains.

[0025] 2. When the range hood is working, the fumes and air in the kitchen are discharged through the range hood. When the range hood is not working, the air circulates in the kitchen, achieving a balance between the air inlet and outlet of the kitchen, making the air pressure in the kitchen more stable.

DETAILED DESCRIPTION

[0030] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0031] Embodiment 1: This embodiment is a smart kitchen air cooling control method, which is implemented by an air cooling device. The device includes a refrigeration unit, an exhaust unit, and an air quality sensor. The air inlet end of the refrigeration unit is connected to the external air inlet channel and the internal air inlet channel through a switching unit. The connection end of the switching unit and the external air inlet channel is provided with a first valve, and the connection end of the switching unit and the internal air inlet channel is provided with a second valve. The refrigeration unit includes a heat dissipation channel, the output end of the exhaust unit is connected to the heat dissipation channel, the output end of the exhaust unit is provided with a third valve, and the heat dissipation channel is provided with a fourth valve upstream of the exhaust unit. The air quality sensor detects the internal air quality. Figure 1 As shown, the control method specifically includes: When the device is turned on, obtain the range hood working signal.

[0032] Specifically, the working state of the device is detected in real time, and when the device is in the on state, the current range hood working signal is obtained.

[0033] When the range hood is working, the control switching unit is connected to the external air inlet channel so that the external air is discharged as cold air through the refrigeration unit.

[0034] As a preferred solution of this embodiment, when a range hood working signal is detected, that is, the range hood is in working state, the first valve is controlled to be opened and the second valve is controlled to be closed.

[0035] Specifically, the switching unit includes a port connected to the air inlet outer channel and a port connected to the air inlet inner channel. A first valve and a second valve are respectively provided on the two ports to control the opening and closing of the channels. When the range hood is in working state, generally when the kitchen is cooking, there is oil smoke in the air, and external air is needed for cooling. The first valve is controlled to open to connect the switching unit with the air inlet outer channel, and the second valve is controlled to close to close the switching unit with the air inlet inner channel to prevent the air with oil smoke in the kitchen from entering the cooling unit. The outside is the space or environment outside the kitchen.

[0036] At the same time, after the range hood working signal is detected, the third valve is controlled to open, the exhaust unit is connected to the heat dissipation channel, the fourth valve is opened, the entire heat dissipation channel is connected to the outside, and the exhaust unit is started to discharge the internal hot air to the outside through the heat dissipation channel. The inside is the kitchen space.

[0037] Specifically, the exhaust unit is arranged on the upper part of the range hood, and the exhaust operation is performed simultaneously when the range hood is working. The third valve is opened, and the output end of the exhaust unit is connected with the heat dissipation channel, and the heat dissipation channel is connected with the outside. The exhaust unit includes an exhaust fan, and the exhaust unit works to discharge a large amount of hot air gathered above the range hood during cooking into the heat dissipation channel. When the refrigeration unit is working, the fourth valve is opened, and the hot air generated by the hot surface of the refrigeration unit is discharged to the outside through the heat dissipation channel, and the hot air in the heat dissipation channel is mixed with the hot air in the exhaust unit and discharged to the outside. The exhaust unit consumes less energy to solve the large amount of heat generated during cooking, and cooperates with the refrigeration unit to achieve a faster cooling effect, while also saving energy.

[0038] When the range hood is not in operation, the control switching unit is connected to the air inlet inner channel so that the internal air is discharged as cold air through the refrigeration unit.

[0039] As a preferred solution of this embodiment, when the range hood working signal is not detected, that is, the range hood is not in working state, the first valve is controlled to be closed and the second valve is controlled to be opened.

[0040] Specifically, when the range hood is not in working state, generally when there is no cooking in the kitchen and there is no oil smoke in the air, the internal air can be used for cooling. The first valve is controlled to be closed, and the switching unit and the external air inlet channel are closed. At the same time, the second valve is controlled to be opened, and the switching unit and the internal air inlet channel are connected. The air in the kitchen enters the refrigeration unit, and flows into the kitchen after being cooled, so that the kitchen air is cooled and the inlet and outlet air balance is achieved.

[0041] At the same time, when it is detected that the range hood is not in working state, the third valve is controlled to be closed, the fourth valve is opened, the entire heat dissipation channel is connected to the outdoors, and the exhaust unit stops working.

[0042] Specifically, when the range hood is not working, there is no hot air gathering on the range hood, and the exhaust unit does not work either. At this time, the third valve is controlled to be closed to prevent the cold air in the kitchen from being discharged from the exhaust unit. When the device is turned on, the refrigeration unit continues to work, the fourth valve is opened, and the hot air generated by the hot surface of the refrigeration unit is discharged to the outside through the heat dissipation channel.

[0043] When the range hood is not in operation, real-time detection of the internal air quality is also included as a preferred solution, including: An air quality threshold is set. When the detected internal air quality value is greater than the air quality threshold, the range hood is controlled to turn on, and at the same time, the switching unit is controlled to connect to the external air inlet channel, that is, the first valve is controlled to open and the second valve is controlled to close, so that the external air is discharged through the refrigeration unit as cold air.

[0044] Specifically, this solution links the air cooling device with the range hood. By setting an air quality sensor, the air quality sensor detects the air quality of the kitchen. When the air quality in the kitchen is poor, that is, when there is a lot of oil in the air, the control switches to the outer air inlet channel to intake air, and at the same time controls the range hood to turn on. While controlling the temperature of the kitchen environment, it can also achieve the purification function, and also prevent the oil from polluting the air cooling device. The air cooling device and the range hood are linked, and the two can communicate via Bluetooth or WiFi, or both can enter the overall smart home system together. The air quality sensor of this solution detects the air quality at intervals set time, and performs the above operation when poor air quality is detected. When poor air quality is not detected, the detection is repeated at intervals set time until the device is turned off, and the detection is also stopped. If the user turns on the range hood during the detection process, the air quality detection is stopped, and the process enters the step of the range hood working state, switching to the outer air inlet channel to intake air.

[0045] The control method of the present invention is linked to the operation of the range hood. When the working state of the kitchen range hood is identified, the control switching unit is switched to the air intake through the outer air intake channel, so that the outside air flows into the kitchen after passing through the refrigeration unit. At the same time, combined with kitchen cooking, the range hood discharges the fumes and air into the kitchen to achieve air balance in the kitchen. When the range hood is identified to be in a non-working state, the control switching unit is switched to the air intake through the inner air intake channel, wherein the interior is the space in the kitchen, so that the internal air enters the refrigeration unit and flows back into the kitchen, and the inlet and outlet air are balanced. While the present invention realizes temperature control in the kitchen, it reduces the pollution of the oil fume to the air cooling device, increases the service life of the air cooling device, reduces the difficulty of cleaning oil stains, and realizes the balance of the inlet and outlet air in the kitchen, so that the air pressure in the kitchen is more stable.

The temperature conductors on both sides of the semiconductor refrigeration plate are respectively located in the air supply channel and the heat dissipation channel.

When the semiconductor refrigeration plate is refrigerating, the temperature conductor on the cold surface cools the passing air, and the temperature conductor on the hot surface, i.e., the heat sink 11, dissipates the heat generated by the hot surface in the heat dissipation channel.

[0048] The input end of the refrigeration unit 1 is connected to the switching unit 3, and the switching unit includes two input ends, which are respectively connected to the external air inlet channel 5 and the internal air inlet channel 6. The external air inlet channel is connected to the room outside the kitchen or the external space, and the internal air inlet channel is connected to the space inside the kitchen. The switching unit 3 opens and closes the external air inlet channel and the internal air inlet channel.

[0049] The control unit is connected to the range hood, obtains the working signal of the range hood 8, and controls the opening and closing of each channel according to the working signal of the range hood 8. Specifically, when the device is in working state, when the control unit detects that the range hood 8 is working, the control unit controls the switching unit to connect the refrigeration unit 1 with the air inlet outer channel 5, so that the external air is cooled by the refrigeration unit, and the cold air is discharged into the kitchen through the air supply channel. When the control unit detects that the range hood is not working, the control unit controls the switching unit to connect the refrigeration unit 1 with the air inlet inner channel 6, draws the air in the kitchen into the refrigeration unit for cooling, and the cold air is then discharged into the kitchen through the air supply channel.

[0059] As a preferred solution of this embodiment, when a range hood working signal is detected, that is, the range hood is in working state, the first valve is controlled to be opened and the second valve is controlled to be closed.

[0060] Specifically, the switching unit includes a port connected to the air inlet outer channel and a port connected to the air inlet inner channel. A first valve and a second valve are respectively provided on the two ports to control the opening and closing of the channels. When the range hood is in working state, generally when the kitchen is cooking, there is oil smoke in the air, and external air is needed for cooling. The first valve is controlled to open to connect the switching unit with the air inlet outer channel, and the second valve is controlled to close to close the switching unit with the air inlet inner channel to prevent the air with oil smoke in the kitchen from entering the cooling unit. The outside is the space or environment outside the kitchen.

[0061] At the same time, after the range hood working signal is detected, the third valve is controlled to open, the exhaust unit is connected to the heat dissipation channel, the fourth valve is opened, the entire heat dissipation channel is connected to the outside, and the exhaust unit is started to discharge the internal hot air to the outside through the heat dissipation channel. The inside is the kitchen space.

[0062] Specifically, the exhaust unit is arranged on the upper part of the range hood, and the exhaust operation is performed simultaneously when the range hood is working. The third valve is opened, and the output end of the exhaust unit is connected with the heat dissipation channel, and the heat dissipation channel is connected with the outside. The exhaust unit includes an exhaust fan, and the exhaust unit works to discharge a large amount of hot air gathered above the range hood during cooking into the heat dissipation channel. When the refrigeration unit is working, the fourth valve is opened, and the hot air generated by the hot surface of the refrigeration unit is discharged to the outside through the heat dissipation channel, and the hot air in the heat dissipation channel is mixed with the hot air in the exhaust unit and discharged to the outside. The exhaust unit consumes less energy to solve the large amount of heat generated during cooking, and cooperates with the refrigeration unit to achieve a faster cooling effect, while also saving energy.

[0063] When the range hood is not in operation, the control switching unit is connected to the air inlet inner channel so that the internal air is discharged as cold air through the refrigeration unit.

[0064] As a preferred solution of this embodiment, when the range hood working signal is not detected, that is, the range hood is not in working state, the first valve is controlled to be closed and the second valve is controlled to be opened.

[0065] Specifically, when the range hood is not in working state, generally when there is no cooking in the kitchen and there is no oil smoke in the air, the internal air can be used for cooling. The first valve is controlled to be closed, and the switching unit and the external air inlet channel are closed. At the same time, the second valve is controlled to be opened, and the switching unit and the internal air inlet channel are connected. The air in the kitchen enters the refrigeration unit, and flows into the kitchen after being cooled, so that the kitchen air is cooled and the inlet and outlet air balance is achieved.

[0066] At the same time, when it is detected that the range hood is not in working state, the third valve is controlled to be closed, the fourth valve is opened, the entire heat dissipation channel is connected to the outdoors, and the exhaust unit stops working.

[0067] Specifically, when the range hood is not working, there is no hot air gathering on the range hood, and the exhaust unit does not work either. At this time, the third valve is controlled to be closed to prevent the cold air in the kitchen from being discharged from the exhaust unit. When the device is turned on, the refrigeration unit continues to work, the fourth valve is opened, and the hot air generated by the hot surface of the refrigeration unit is discharged to the outside through the heat dissipation channel.

[0068] When the range hood is not in operation, real-time detection of the internal air quality is also included as a preferred solution, including: An air quality threshold is set. When the detected internal air quality value is greater than the air quality threshold, the range hood is controlled to turn on, and at the same time, the switching unit is controlled to connect to the external air inlet channel, that is, the first valve is controlled to open and the second valve is controlled to close, so that the external air is discharged through the refrigeration unit as cold air.

[0069] Specifically, this solution links the air cooling device with the range hood. By setting an air quality sensor, the air quality sensor detects the air quality of the kitchen. When the air quality in the kitchen is poor, that is, when there is a lot of oil in the air, the control switches to the outer air inlet channel to intake air, and at the same time controls the range hood to turn on. While controlling the temperature of the kitchen environment, it can also achieve the purification function, and also prevent the oil from polluting the air cooling device. The air cooling device and the range hood are linked, and the two can communicate via Bluetooth or WiFi, or both can enter the overall smart home system together. The air quality sensor of this solution detects the air quality at intervals set time, and performs the above operation when poor air quality is detected. When poor air quality is not detected, the detection is repeated at intervals set time until the device is turned off, and the detection is also stopped. If the user turns on the range hood during the detection process, the air quality detection is stopped, and the process enters the step of the range hood working state, switching to the outer air inlet channel to intake air.

[0070] The control method of the present invention is linked to the operation of the range hood. When the working state of the kitchen range hood is identified, the control switching unit is switched to the air intake through the outer air intake channel, so that the outside air flows into the kitchen after passing through the refrigeration unit. At the same time, combined with kitchen cooking, the range hood discharges the fumes and air into the kitchen to achieve air balance in the kitchen. When the range hood is identified to be in a non-working state, the control switching unit is switched to the air intake through the inner air intake channel, wherein the interior is the space in the kitchen, so that the internal air enters the refrigeration unit and flows back into the kitchen, and the inlet and outlet air are balanced. While the present invention realizes temperature control in the kitchen, it reduces the pollution of the oil fume to the air cooling device, increases the service life of the air cooling device, reduces the difficulty of cleaning oil stains, and realizes the balance of the inlet and outlet air in the kitchen, so that the air pressure in the kitchen is more stable.

[0071] Further, when the device is in a shutdown state, a range hood operation signal is obtained; When the range hood is working, the third valve is controlled to be opened, the fourth valve is controlled to be closed, and the exhaust unit is controlled to be started at the same time.

[0072] Specifically, when the air cooling device is not turned on, when the range hood is working, the oil smoke is discharged to the outside through the range hood, but the hot air generated by cooking accumulates above the range hood. At this time, the exhaust unit is turned on to discharge the hot air to the outside without turning on the refrigeration unit. At the same time, the control is based on the setting structure of the exhaust unit. The exhaust unit is connected to the heat dissipation channel. The radiator of the refrigeration unit is set in the heat dissipation channel and is located upstream of the connection of the exhaust unit. The input end of the heat dissipation channel is connected to the air inlet channel. A heat dissipation fan is also set in the heat dissipation channel. The heat dissipation fan is located between the connection of the radiator and the exhaust unit. The heat dissipation channel takes in air through the air inlet channel to take away the heat of the radiator, and then the hot air exhausted by the exhaust unit is discharged to the outside. When the device is turned off, the heat dissipation fan does not work, the exhaust unit is started alone, the fourth valve is closed, and the upstream of the heat dissipation channel is closed to prevent the hot air with oil from entering the upstream of the heat dissipation channel and causing oil pollution to the radiator, and to prevent the oily air from flowing back. When the fourth valve is provided, when the device is turned on, it is detected that the range hood is working, the fourth valve is controlled to open, the third valve is opened, the exhaust unit is operated, and the heat dissipation and exhaust together discharge the air to the outdoors.
