However, when the refrigeration module is working, it will also generate heat.

At the same time, the term "and / or" used in this specification includes any and all combinations of the relevant listed items.

[0059] In one embodiment, Figure 1 As shown, a range hood is provided, including a range hood module, a refrigeration module and an air guide module. The range hood module is provided with a vent, the heat dissipation port of the refrigeration module is fluidly connected with the vent, and the air guide module is arranged at the vent; the range hood module is used to absorb and discharge the oil smoke in the target area; the refrigeration module is used to cool the target area, and the target area is the action area of ​​the range hood; the air guide module is a movable air guide module, and the air guide module is used to change the shape of the vent when moving. Thus, the heat generated by the refrigeration module can reach the range hood module through the heat dissipation port and the vent, and be discharged through the range hood module to reduce the temperature of the refrigeration module. In addition, by arranging a movable air guide module at the vent, the shape of the vent can be adjusted in different usage scenarios, which is conducive to better introducing the heat dissipated by the refrigeration module into the range hood module for discharge, and can effectively reduce the oil smoke sucked by the range hood module from flowing back into the refrigeration module, causing the refrigeration module to be contaminated and reduce the working performance, and the use flexibility is high, thereby improving the working reliability of the range hood.

[0060] The target area is the effective area of ​​the range hood. For example, when the range hood is used in a kitchen, the effective area for absorbing oil fumes is the kitchen. The range hood can absorb oil fumes in the kitchen, and the target area is the kitchen.

[0061] The range hood module can form negative pressure when working, so that the oil smoke in the target area can be sucked in through the oil smoke inlet and discharged through the oil smoke outlet, for example, to a public flue or outdoors, thereby reducing the oil smoke in the target area.

[0062] The refrigeration module is used to cool the target area. The type of refrigeration module is not limited, as long as the refrigeration function can be achieved. Exemplarily, the refrigeration module may include a compressor, a heat dissipation module and an indoor module, and the compressor, the heat dissipation module and the indoor module are connected to form a refrigeration cycle. The refrigeration cycle is carried out in the refrigeration cycle, including a compression process in the compressor, a condensation process in the heat dissipation module, an expansion process in the connecting pipe and an evaporation process in the indoor module. The limited refrigerant is used in a closed refrigeration system to repeatedly compress, condense, expand and evaporate the refrigerant, and continuously absorb heat and vaporize at the indoor module, which plays a role in refrigeration and cooling. The condensation process in the heat dissipation module generates heat, which can be discharged through the heat dissipation port of the heat dissipation module. The heat dissipation port of the heat dissipation module is fluidly connected to the vent as the heat dissipation port of the refrigeration module. Thus, the heat generated during the condensation process can reach the range hood module through the heat dissipation port and the vent, and be discharged through the range hood module. When the refrigeration module includes a compressor, a heat dissipation module and an indoor module, the refrigeration effect is good and the cooling effect is obvious.

[0063] In an extensible manner, the refrigeration module may also be other structures, such as a fan module. The fan module is used to supply air to the target area, so that airflow circulates in the target area to cool down. For example, the fan module can supply air to the cook in the kitchen to accelerate the airflow speed and reduce the temperature of the blowing part of the cook. The structure of the fan module is not unique. For example, in one embodiment, the fan module includes an air inlet, an air outlet and a wind wheel, and the wind wheel is arranged between the air inlet and the air outlet, and the air inlet and the air outlet are connected to the target area. The fan module absorbs the wind in the target area through the air inlet and supplies air to the target area through the air outlet. When the wind wheel rotates, the air in the target area can pass through the air inlet, the wind wheel and the air outlet in sequence to complete the air circulation, accelerate the flow speed of the air in the target area, and play a role in cooling down. When the refrigeration module includes a fan module, the heat dissipation port of the refrigeration module can be an area close to the device that generates heat when working in the fan module, such as an area close to the wind wheel.

[0064] The wind guide module is arranged at the vent, which can change the path of the airflow passing through the vent, and play a role in guiding the air. Furthermore, the wind guide module is a movable wind guide module, which means that the wind guide module can move in the vent. In addition, the wind guide module can change the shape of the vent when it moves. Exemplarily, when the wind guide module moves to different positions or different shapes, the structure formed in the vent is different, which can change the shape of the vent, and thus the wind guiding effect on the vent is also different. The wind guide module is a movable wind guide module, and its position and state are changeable, and it is highly flexible. It can be in different forms in different scenarios, thereby improving the ventilation performance of the vent.

[0065] In this embodiment, the range hood includes a range hood module, a refrigeration module and an air guide module. The range hood module is provided with a vent, the heat dissipation port of the refrigeration module is fluidly connected to the vent, the air guide module is arranged at the vent, the range hood module is used to absorb and discharge the oil smoke in the target area, the refrigeration module is used to cool the target area, the target area is the action area of ​​the range hood, and the air guide module is a movable air guide module, and the air guide module is used to change the shape of the vent when moving. Thus, the heat generated by the refrigeration module can reach the range hood module through the heat dissipation port and the vent, and be discharged through the range hood module to reduce the temperature of the refrigeration module. In addition, by arranging a movable air guide module at the vent, the shape of the vent can be adjusted in different usage scenarios, which is conducive to better introducing the heat dissipated by the refrigeration module into the range hood module for discharge, and can effectively reduce the occurrence of the oil smoke sucked by the range hood module backflowing into the refrigeration module, causing the refrigeration module to be contaminated and reduce the working performance, and the use flexibility is high, thereby improving the working reliability of the range hood.

[0066] The structure of the wind guide module is not unique. For example, in one embodiment, Figure 2 As shown, the wind guide module includes a driving component 34 and a wind guide plate 33. The driving component 34 is connected to the wind guide plate 33. The wind guide plate 33 is arranged at the vent. The driving component 34 is used to drive the wind guide plate 33 to move.

[0067] The driving assembly 34 can provide power for the movement of the air guide plate 33. The driving assembly 34 is connected to the air guide plate 33. When the driving assembly 34 moves, it can drive the air guide plate 33 to move, thereby achieving the function of driving the air guide plate 33 to move. The type of the driving assembly 34 is not limited, as long as it can drive the air guide plate 33 to move. Exemplarily, the driving assembly 34 can be a motor. The motor is connected to the air guide plate 33, and when the motor moves, it can drive the air guide plate 33 to move.

[0068] The air guide plate 33 moves under the drive of the driving assembly 34. The air guide plate 33 is set at the vent, and the air guide plate 33 can change the shape of the vent during the movement. The shape of the air guide plate 33 is not unique. For example, the air guide plate 33 can be a plate-like structure, for example, a plate-like structure with a small thickness, which can change the shape of the vent over a large area. Alternatively, the air guide plate 33 can also be a long strip structure, which is convenient for changing the size of the vent by changing the length, and the specific shape can be determined according to actual needs.

[0069] When the air guide plate 33 moves to different positions, the vent can be in different forms. For example, when the air guide plate 33 moves to different angles, the path of the airflow passing through the vent can be formed into corresponding angles to meet the needs of different scenarios. When the air guide angle moves to completely close the vent, the vent is closed and ventilation cannot be achieved.

[0070] In this embodiment, the wind guide module includes a driving component 34 and an wind guide plate 33. The driving component 34 is connected to the wind guide plate 33. The wind guide plate 33 is arranged at the vent. The driving component 34 is used to drive the wind guide plate 33 to move so that the wind guide plate 33 moves at the vent, thereby changing the shape of the vent and enriching the wind guiding state.

[0071] In an exemplary embodiment, Figure 3 As shown, the driving component includes a push rod motor 6, and the air guide plate includes a first air guide plate 331 and a second air guide plate 332. The push rod motor 6 is arranged on the first air guide plate 331 and connected to the second air guide plate 332. The driving component is used to drive the second air guide plate 332 to move on the first air guide plate 331 to adjust the length of the second air guide plate 332 extending out of the first air guide plate 331.

[0072] The push rod motor 6 is disposed on the first air guide plate 331 , and the first air guide plate 331 can make the position of the push rod motor 6 relatively fixed, thereby helping the push rod motor 6 to work normally.

[0073] The push rod motor 6 is connected to the second air guide plate 332 and is used to drive the second air guide plate 332 to move. When the push rod motor 6 is powered on, the magnetic conductive material in the stator generates a magnetic field, and the conductive material in the rotor generates an electromagnetic torque after being powered on. Since the speed of the rotor is higher than the speed of the stator, the electromagnetic torque on the rotor transmits the torque to the reducer, and the reducer reduces the speed and increases the torque, and finally outputs mechanical energy through the push rod to push the second air guide plate 332 to perform the push rod action.

[0074] When the push rod motor 6 pushes the second air guide plate 332 to perform the push rod action, the second air guide plate 332 moves on the first air guide plate 331. It can be understood that the first air guide plate 331 and the second air guide plate 332 are arranged in parallel. The second air guide plate 332 moves on the first air guide plate 331, and the length of the second air guide plate 332 extending out of the first air guide plate 331 can be adjusted by changing the overlapping length of the first air guide plate 331 and the second air guide plate 332. Let the length of the air guide plate be the sum of the length of the first air guide plate 331 and the length of the second air guide plate 332 minus the overlapping length of the first air guide plate 331 and the second air guide plate 332, then the push rod motor 6 can adjust the length of the second air guide plate 332 extending out of the first air guide plate 331 by driving the second air guide plate 332 to move on the first air guide plate 331, thereby adjusting the total length of the air guide plate.

[0075] Taking the first air guide plate 331 and the second air guide plate 332 as an example, the second air guide plate 332 can move to the left or right, so that the second air guide plate 332 extends out of the first air guide plate 331 to different lengths. It can be understood that, depending on the different length relationships between the first air guide plate 331 and the second air guide plate 332, there may be a situation where the second air guide plate 332 does not extend out of the first air guide plate 331. In this case, it can be considered that the length of the air guide plate is the shortest.

[0076] In this embodiment, the driving component includes a push rod motor 6, and the air guide plate includes a first air guide plate 331 and a second air guide plate 332. The push rod motor 6 is arranged on the first air guide plate 331 and connected to the second air guide plate 332. The driving component is used to drive the second air guide plate 332 to move on the first air guide plate 331 to adjust the length of the second air guide plate 332 extending out of the first air guide plate 331, thereby changing the size of the vent and adjusting the flow rate and speed of the airflow passing through the vent.

[0077] Further, in one embodiment, if Figure 3 As shown, the driving assembly further includes a rotating motor 5, which is connected to the first air guide plate 331, and is used to drive the first air guide plate 331 to rotate.

[0078] The rotating motor 5 is connected to the first air guide plate 331. When the rotating motor 5 is powered on, the current generates a magnetic field, and the magnetic field interacts with the conductor to generate a force, thereby rotating the rotating motor 5. The rotating motor 5 is connected to the first air guide plate 331. When the rotating motor 5 rotates, the first air guide plate 331 is driven to rotate. The first air guide plate 331 can be rotated to different angles, thereby changing the path of the airflow flowing through the vent.

[0079] It can be understood that when the rotating motor 5 drives the first air guide plate 331 to rotate, the second air guide plate 332 arranged on the first air guide plate 331 can be rotated synchronously, thereby changing the angle of the overall structure formed by the first air guide plate 331 and the second air guide plate 332.

[0080] In this embodiment, the driving assembly further includes a rotating motor 5, which is connected to the first air guide plate 331 and is used to drive the first air guide plate 331 to rotate. Thus, the rotating motor 5 can control the angle of the first air guide plate 331 and the angle of the overall structure formed by the first air guide plate 331 and the second air guide plate 332, so as to adjust the air guide angle of the air guide plate and the shape of the vent.

[0081] Furthermore, the structure of the rotating motor 5 is not unique. In an exemplary embodiment, Figure 3As shown, the rotating motor 5 includes a motor body, a rotating shaft 51 and a motor wire 52 . The motor wire 52 is connected to the motor body. The rotating shaft 51 is located at the center of the motor body. The rotating shaft 51 is connected to the first air guide plate 331 .

[0082] Among them, the motor wire 52 is connected to the motor body, and the motor wire 52 is used to connect the external current to the motor body. The motor body generates a magnetic field after being energized, so that the rotating shaft 51 rotates. The rotating shaft 51 is connected to the first air guide plate 331. When the rotating shaft 51 rotates, it drives the first air guide plate 331 to rotate, and drives the second air guide plate 332 and the push rod motor 6 arranged on the first air guide plate 331 to rotate synchronously, so as to change the angle of the first air guide plate 331 and the second air guide plate 332, thereby changing the shape of the vent. It can be understood that in other embodiments, the rotating motor 5 can also include other structures, which are not limited here.

[0083] In this embodiment, the rotating motor 5 includes a motor body, a rotating shaft 51 and a motor wire 52. The motor wire 52 is connected to the motor body, and the rotating shaft 51 is located at the center of the motor body. The rotating shaft 51 is connected to the first air guide plate 331. After the current is connected through the motor wire 52, the rotating shaft 51 can be rotated, thereby driving the first air guide plate 331 to rotate, and driving the second air guide plate 332 and the push rod motor 6 disposed on the first air guide plate 331 to rotate synchronously, so as to change the angle of the first air guide plate 331 and the second air guide plate 332, thereby changing the shape of the vent.

[0084] In an exemplary embodiment, the range hood further includes a controller, which is connected to the air guide module and is used to control the movement of the air guide module.

[0085] The controller can be used as a central control device to control the movement of the air guide module so that the air guide module is in a specific position and the ventilation state of the vent meets the requirements.

[0086] Exemplarily, the controller can control the working state of the air guide module according to the received signal. For example, when the controller receives a signal indicating that the cooling mode of the range hood is not turned on, the controller can control the air guide module to move to a state where the vents can be closed. When the cooling mode of the range hood is not turned on, the refrigeration module will not work and will not generate heat. At this time, there is no need to introduce the generated heat into the range hood module. Therefore, controlling the air guide module to move to a state where the vents can be closed can also prevent the fumes inhaled by the range hood module from entering the refrigeration module and affecting the performance of the refrigeration module. It can be understood that in other embodiments, the functions of the controller can also include others, and adaptive settings can be made according to actual needs, which will not be repeated here.

[0087] In addition, the structure of the refrigeration module is not unique. In an exemplary embodiment, Figure 4 As shown, the refrigeration module includes a compressor 2, a heat dissipation module 3 and an indoor module 4. The compressor 2, the heat dissipation module 3 and the indoor module 4 are connected and the heat dissipation port of the heat dissipation module 3 serves as the heat dissipation port of the refrigeration module.

[0088] The compressor 2, the heat dissipation module 3 and the indoor module 4 are connected to form a refrigeration cycle. The refrigeration cycle is carried out in the refrigeration cycle, including a compression process in the compressor 2, a condensation process in the heat dissipation module 3, an expansion process in the connecting pipe, and an evaporation process in the indoor module 4. The limited refrigerant is used in a closed refrigeration system to repeatedly compress, condense, expand, and evaporate the refrigerant, and continuously absorb heat and vaporize at the indoor module 4, thereby playing a role in cooling and cooling. The condensation process in the heat dissipation module 3 generates heat, which can be discharged through the heat dissipation port of the heat dissipation module 3. The heat dissipation port of the heat dissipation module 3 serves as the heat dissipation port of the refrigeration module and is fluidly connected to the vent. Therefore, the heat generated during the condensation process can reach the range hood module through the heat dissipation port and the vent, and be discharged through the range hood module.

[0089] In this embodiment, the refrigeration module includes a compressor 2, a heat dissipation module 3 and an indoor unit module 4, and has a good refrigeration effect and an obvious temperature reduction effect.

[0090] In addition, the structure of the heat dissipation module 3 is not unique. In an exemplary embodiment, Figure 4 As shown, the heat dissipation module 3 includes a condenser 32 and a heat dissipation fan 31 . The condenser 32 , the compressor 2 and the internal unit module 4 are connected and arranged. The heat dissipation fan 31 is used to dissipate the heat discharged by the condenser 32 .

[0091] The condenser 32, the compressor 2 and the indoor module 4 are connected to form a refrigeration cycle. The refrigeration cycle is carried out in the refrigeration cycle, including the compression process in the compressor 2, the condensation process in the condenser 32 and the evaporation process in the indoor module 4. Inside the condenser 32, the high-temperature and high-pressure gaseous refrigerant exchanges heat with the outside air through fine pipes and heat sinks. During the heat exchange process, the heat discharged by the condenser 32 is dissipated through the heat dissipation fan 31 and the heat is dissipated to the external environment. Afterwards, the heat in the external environment reaches the range hood module through the heat dissipation port and the vent, and is discharged through the range hood module.

[0092] As the heat is dissipated, the gaseous refrigerant gradually cools and turns into liquid. Although the pressure decreases, it still remains at a high level. The liquid refrigerant then enters the expansion valve, reducing its pressure and temperature, and then continues to enter the indoor module 4 to start a new round of refrigeration cycle.

[0093] In this embodiment, the heat dissipation module 3 includes a condenser 32 and a heat dissipation fan 31. The condenser 32, the compressor 2 and the internal unit module 4 are connected and arranged. The heat dissipation fan 31 is used to dissipate the heat discharged by the condenser 32. The condenser 32 can form a refrigeration cycle with the compressor 2 and the internal unit module 4 to cool in the refrigeration cycle. The heat dissipation fan 31 can dissipate the heat discharged by the condenser 32 and dissipate the heat to the external environment. Afterwards, the heat in the external environment reaches the range hood module through the heat dissipation port and the vent, and is discharged through the range hood module, which can improve the heat exchange efficiency of the condenser 32.

[0094] In an exemplary embodiment, Figure 4 As shown, the internal unit module 4 includes an evaporator 42 , and the evaporator 42 is connected to the condenser 32 .

[0095] The compressor 2, the condenser 32 and the evaporator 42 are connected to form a refrigeration cycle. The evaporation process is carried out in the evaporator 42, and the refrigerant absorbs heat and vaporizes at the evaporator 42, which plays a role in cooling and lowering the temperature.

[0096] The evaporator 42 includes a heating chamber and an evaporation chamber. The heating chamber provides the liquid with heat required for evaporation, causing the liquid to boil and vaporize. The evaporation chamber completely separates the gas and liquid phases, and the steam is discharged from the evaporator 42, and the concentrated liquid is discharged from the corresponding outlet, thereby completing the evaporation process.

[0097] In this embodiment, the internal unit module 4 includes an evaporator 42, which is connected to the condenser 32 and can form a refrigeration cycle with the condenser 32 and the compressor 2 to achieve refrigeration. The evaporator 42 is energy-efficient, has a wide range of applications, and is flexible to operate.

[0098] The structure of the range hood module is not unique. For example, in one embodiment, Figure 4 As shown, the range hood module includes a centrifugal fan 11 and a housing 111. The centrifugal fan 11 is disposed in the housing 111. When the centrifugal fan 11 rotates, negative pressure can be generated to absorb oil smoke. The centrifugal fan 11 is disposed in the housing 111. The housing 111 can protect the centrifugal fan 11 and limit the inhaled oil smoke to a certain range to reduce the impact on other devices. A vent is provided in the housing 111. The vent is fluidically connected to the heat dissipation port of the refrigeration module, so that the heat generated by the refrigeration module can reach the range hood module through the heat dissipation port and the vent, and then be discharged through the range hood module. It can be understood that in other embodiments, the range hood module can also include other devices, such as filter devices, etc., which are not limited here.

[0099] The structure of the centrifugal fan 11 is also not unique, and may include, for example, a volute, an impeller 112, and a volute tongue 113, wherein the volute tongue 113 is mounted on the housing 111 and close to the vent. It is understood that in other embodiments, the structure of the centrifugal fan 11 may also be other, which is not limited here.

[0100] In this embodiment, the range hood module includes a centrifugal fan 11 and a housing 111. The centrifugal fan 11 is disposed in the housing 111, and the housing 111 is provided with the ventilation opening. The centrifugal fan 11 can absorb oil smoke, and the housing 111 can protect the centrifugal fan 11, and can also limit the inhaled oil smoke within a certain range, thereby reducing the impact on other devices. In addition, the ventilation opening provided in the housing 111 is fluidically connected to the heat dissipation opening of the refrigeration module, so that the heat generated by the refrigeration module can reach the range hood module through the heat dissipation opening and the ventilation opening, and then be discharged through the range hood module, which is conducive to ensuring the working performance of the refrigeration module.

[0101] Based on the range hood provided by any of the above embodiments, the present application also provides a range hood control method, which can be executed based on a controller or a terminal or server that is connected to the range hood. Figure 5 As shown, the range hood control method includes the following steps:

[0102] Step 502, obtaining the working mode of the range hood.

[0103] The working modes of the range hood include a range hood only mode, a range hood plus cooling mode, etc. In the range hood only mode, the range hood module works, and the cooling module does not work. In the range hood plus cooling mode, both the range hood module and the cooling module work.

[0104] Step 504, when the working mode is the non-cooling mode, control the air guide module to move until the vent is closed.

[0105] Among them, when the working mode of the range hood is the non-refrigeration mode, it means that the refrigeration module is not working at this time. It can be understood that the range hood module can work or not work, which is not limited here.

[0106] When the refrigeration module is not working, the controller can control the air guide module to move until it reaches a position where the vent can be closed, and the vent is closed. Since the refrigeration module generates almost no heat when it is not working, there is no need to introduce the heat into the range hood module. In addition, closing the vent at this time can also prevent the oil smoke inhaled by the range hood module from entering the refrigeration module and affecting the working performance of the refrigeration module.

[0107] Step 506: When the working mode is the cooling mode, control the air guide module to open the vents.

[0108] When the working mode of the range hood is the cooling mode, it means that the cooling module is working at this time. It is understandable that the range hood module can work or not work at this time, and generally works, but this is not limited here.

[0109] When the refrigeration module is working, the controller can control the movement of the air guide module to open the vents, which is conducive to better introducing the heat emitted by the refrigeration module into the range hood module for discharge, and can effectively reduce the occurrence of oil smoke inhaled by the range hood module flowing back into the refrigeration module, causing the refrigeration module to be contaminated and reducing working performance. It has high flexibility in use, thereby improving the working reliability of the range hood.

[0110] In this embodiment, after obtaining the working mode of the range hood, when the working mode is non-refrigeration mode, the air guide module is controlled to move until the vent is closed, and when the working mode is cooling mode, the air guide module is controlled to open the vent. The shape of the vent can be adjusted in different usage scenarios, which is conducive to better introducing the heat emitted by the cooling module into the range hood module for discharge, and can effectively reduce the occurrence of oil smoke sucked by the range hood module flowing back into the cooling module, causing the cooling module to be contaminated and reducing the working performance. The use flexibility is high, thereby improving the working reliability of the range hood.

[0111] In an exemplary embodiment, Figure 6 As shown, step 506 includes step 606 and step 608 .

[0112] Step 606, when the working mode is the cooling mode, obtain the smoke exhaust rotation speed of the range hood module.

[0113] The exhaust speed of the range hood module represents the absorption intensity of the range hood module to oil smoke. The greater the exhaust speed of the range hood module, the greater the absorption intensity of the oil smoke; the smaller the exhaust speed of the range hood module, the smaller the absorption intensity of the oil smoke.

[0114] Step 608, controlling the air guide module to move to a target position corresponding to the smoke exhaust rotation speed, and opening the vent.

[0115] Among them, there is a corresponding relationship between the exhaust speed and the target position. The corresponding relationship between the exhaust speed and the target position can be obtained by controlling the movement of the air guide module after the exhaust speed is determined, so that the target position is more compatible with the current exhaust speed. Alternatively, the corresponding relationship between the exhaust speed and the target position can also be obtained in advance through experiments and other means, stored in the controller, and can be directly called when used, which is convenient to use.

[0116] When the working mode is cooling mode, it is necessary to control the air guide module to move to a position where the vent can be opened. In this case, the exhaust speed of the range hood module is first obtained, and then the target position corresponding to the exhaust speed is determined, and then the air guide module is controlled to move to the target position to open the vent. When the air guide module is in the target position, the current ventilation pattern of the vent can be more matched with the current exhaust speed, which can better help the heat dissipated by the refrigeration module to be introduced into the range hood module for discharge, and can greatly reduce the oil smoke inhaled by the range hood module from backflowing into the refrigeration module, causing the refrigeration module to be contaminated and reduce the working performance.

[0117] In this embodiment, when the working mode is the cooling mode, the smoke exhaust speed of the range hood module is obtained, the air guide module is controlled to move to the target position corresponding to the smoke exhaust speed, and the vent is opened. When the air guide module is in the target position, the current ventilation pattern of the vent can be made to better match the current smoke exhaust speed, which can better help the heat dissipated by the refrigeration module to be introduced into the range hood module for discharge, and can greatly reduce the oil smoke inhaled by the range hood module from flowing back into the refrigeration module, causing the refrigeration module to be contaminated and reduce the working performance.

[0118] Further, in an exemplary embodiment, the corresponding relationship between the exhaust speed and the target position can be obtained by controlling the movement of the air guide module after the exhaust speed is determined, such as Figure 7 As shown, the range hood control method further includes steps 702 to 706.

[0119] Step 702: Under the current smoke exhaust speed, the air guide module is controlled to move within a preset movement range.

[0120] The preset motion range is a predetermined range value. Depending on the structure of the wind guide module, the preset motion range will be different. For example, if the wind guide module is an adjustable length wind guide module, the preset motion range may be a length range; if the wind guide module is an adjustable rotation angle wind guide module, the preset motion range may be an angle range.

[0121] Step 704: during the movement of the air guide module, obtain the heat dissipation rotation speed of the refrigeration module.

[0122] The heat dissipation speed of the refrigeration module represents the heat dissipation intensity of the heat dissipation module of the refrigeration module. The greater the heat dissipation speed, the greater the heat dissipation intensity; the smaller the heat dissipation speed, the smaller the heat dissipation intensity.

[0123] In the process of controlling the air guide module to move within the preset range of motion, when the air guide module is in different positions or states, the corresponding heat dissipation speed may be different. During the movement of the air guide module, the controller obtains the heat dissipation speed of the cooling module, so as to facilitate subsequent comparison based on the heat dissipation speed corresponding to each position.

[0124] Step 706: The position of the air guide module corresponding to the minimum value of the heat dissipation rotation speed is used as the target position corresponding to the smoke exhaust rotation speed.

[0125] After the controller obtains the heat dissipation speeds corresponding to the different positions of the air guide module, it determines the minimum heat dissipation speed from the various heat dissipation speeds, and then uses the position of the air guide module corresponding to the minimum heat dissipation speed as the target position corresponding to the smoke exhaust speed. It can be understood that when the air guide module is at the target position, the smaller the demand for the heat dissipation speed is, the more energy saving is achieved on the basis of achieving the heat dissipation effect.

[0126] In addition, depending on the structure of the wind guide module, the specific means of determining the target position corresponding to the smoke exhaust speed may be different. Figure 8 As shown, the range hood control method further includes steps 802 to 810.

[0127] Step 802: Under the current smoke exhaust rotation speed, the air guide module is controlled to move until the length reaches a preset length, and then the air guide module is controlled to rotate.

[0128] This step is based on the structure of the wind guide module with adjustable length and adjustable rotation angle. The preset length can be obtained through pre-factory testing. Since the range of the length that the wind guide module can be extended and retracted may be large, the length range of the wind guide module corresponding to the minimum heat dissipation speed is reduced in advance through testing, and the middle value of the reduced length range of the wind guide module is used as the preset length. When using, the user can quickly determine the optimal preset length.

[0129] Step 804: during the rotation of the air guide module, the heat dissipation rotation speed of the refrigeration module is obtained, and the target angle corresponding to the minimum heat dissipation rotation speed is detected.

[0130] The exhaust speed can be reflected by the speed of the centrifugal fan in the smoke exhaust module, and the heat dissipation speed of the refrigeration module can be reflected by the speed of the heat dissipation fan of the heat dissipation module in the refrigeration module.

[0131] When the air guide module is at different angles, the heat dissipation speed of the corresponding cooling module may be different. During the rotation of the air guide module, the heat dissipation speed of the cooling module is obtained, and the target angle corresponding to the minimum heat dissipation speed is detected.

[0132] Step 806, controlling the air guide module to rotate to a target angle and then stop rotating, and controlling the air guide module to telescope.

[0133] The target angle corresponding to the minimum heat dissipation rotation speed indicates that when the air guide module is at the target angle, the demand for the heat dissipation rotation speed is the minimum compared to other angles. The air guide module is controlled to stop rotating after rotating to the target angle, and the air guide module is controlled to telescope.

[0134] Step 808, during the telescopic movement of the air guide module, the heat dissipation rotation speed of the refrigeration module is obtained, and the target length corresponding to the minimum heat dissipation rotation speed is detected.

[0135] When the air guide module is in different length states, the heat dissipation speed of the corresponding refrigeration module may be different. During the extension and retraction of the air guide module, the heat dissipation speed of the refrigeration module is obtained, and the target length corresponding to the minimum heat dissipation speed is detected. The target length corresponding to the minimum heat dissipation speed indicates that when the air guide module is at the target length, the demand for the heat dissipation speed is the smallest relative to other lengths.

[0136] Step 810: taking the target angle and the target length as the target position corresponding to the smoke exhaust rotation speed.

[0137] Afterwards, a corresponding relationship is established between the determined target angle and target length and the current smoke exhaust rotation speed, and the position determined by the target angle and target length is used as the target position corresponding to the smoke exhaust rotation speed.

[0138] In this embodiment, under the current smoke exhaust speed, the wind guide module is controlled to move until the length reaches the preset length, and then the wind guide module is controlled to rotate; during the rotation of the wind guide module, the heat dissipation speed of the refrigeration module is obtained, and the target angle corresponding to the minimum heat dissipation speed is detected; after the wind guide module is controlled to rotate to the target angle, it stops rotating, and the wind guide module is controlled to telescopically move; during the telescopic movement of the wind guide module, the heat dissipation speed of the refrigeration module is obtained, and the target length corresponding to the minimum heat dissipation speed is detected; the target angle and target length are used as the target position corresponding to the smoke exhaust speed. Thus, the target angle and target length corresponding to the smoke exhaust speed can be accurately determined, and the target position can be obtained, which is conducive to improving the accurate control of the wind guide module.

[0139] In order to better understand the above embodiment, a detailed explanation is given below in conjunction with a specific embodiment. Figure 1-4 As shown, the range hood includes a range hood module 1, a refrigeration module and an air guide module, the air guide module includes a driving assembly and an air guide plate, the driving assembly includes a push rod motor 6 and a rotating motor 5, the air guide plate includes a first air guide plate 331 and a second air guide plate 332, the first air guide plate is an air guide rotating plate, and the second air guide plate 332 is an air guide push plate. The rotating motor 5 includes a motor body, a rotating shaft 51 and a motor wire 52.

[0140] The refrigeration module includes a compressor 2, a heat dissipation module 3 and an indoor module 4. The indoor module 4 includes an evaporator 42 and an indoor fan 41, and the smoke exhaust module 1 includes a centrifugal fan 11, an upper box 12, an air inlet 13 and an outer shell 111. The centrifugal fan 11 is installed inside the upper box 12, the air inlet 13 is installed at the bottom of the upper box 12, and the air inlet 13 is provided with an oil smoke inlet connected to the air inlet of the centrifugal fan 11. The centrifugal fan 11 includes an impeller 112 and a volute tongue 113, and the volute tongue 113 is installed on the outer shell ring wall 115 and close to the fan outlet. The compressor 2 is installed above the air inlet 13 and is located on the right side of the upper box 12, and the indoor module 4 is arranged above the compressor 2. The heat dissipation module 3 is arranged at the top of the upper box 12, and the heat dissipation module 3 and the indoor module 4 are arranged adjacent to each other, and the heat dissipation module 3 and the indoor module 4 share the air inlet.

[0141] The compressor 2, condenser 32 and evaporator 42 constitute an air conditioning component, and its specific working principle is the same as that of the air conditioner, which will not be described in detail here. An internal unit air outlet 43 is opened at the upper part of the air inlet body 13, and the air outlet of the internal unit fan 41 is fluidly connected to the internal unit air outlet 43 through the air guide channel. When working in the cooling mode, cold air is blown out from the internal unit air outlet 43 to improve the user's cooking experience.

[0142] In this embodiment, the heat dissipation fan 31 is a centrifugal fan, and the central axis of the impeller of the heat dissipation fan 31 is parallel to the central axis of the impeller of the centrifugal fan 11. A vent 114 is provided on the volute ring wall 115 of the centrifugal fan 11, and the heat dissipation fan 31 is arranged above the centrifugal fan 11, and the air outlet of the heat dissipation fan 31 faces downward and toward the vent 114, and the air outlet of the heat dissipation fan 31 is fluidly connected with the vent 114. A movable air guide module 33 is provided at the vent 114, and the air guide module 33 can be rotated to a suitable angle and cover the vent 114 by a suitable length, so that the hot air blown out by the heat dissipation fan 31 can overcome the wind pressure in the centrifugal fan 11, and smoothly be introduced into the interior of the housing 111, and can also prevent the wind in the housing 111 from overflowing outward through the vent 114.

[0143] like Figure 3As shown, the air guide plate 33 includes an air guide rotating plate and an air guide push plate, and the air guide rotating plate is connected to the rotating shaft 51 of the rotating motor 5. One end of the air guide rotating plate has an elliptical groove, which is fixedly connected to the rotating shaft 51 of the rotating motor 5. After the rotating motor 5 receives the rotation instruction, the rotating motor shaft 51 will rotate, thereby driving the air guide rotating plate to rotate. And the optimal rotation angle determined by each gear is input into the controller to control the rotating motor 5 to rotate the corresponding angle under different gears. When the rotating motor wire 52 is energized, the air guide plate 331 can be rotated. The push rod motor 6 is fixed on the air guide rotating plate, and the air guide push plate is connected to the push rod motor 6. The push rod motor 6 can control the extension length of the air guide push plate, thereby controlling the length of the air guide plate 33. The length of the air guide plate 33 is the sum of the lengths of the air guide rotating plate and the air guide push plate minus the overlapping length of the air guide rotating plate and the air guide push plate.

[0144] In this embodiment, a rotatable and retractable air guide plate is provided at the vent, so that the position of the air guide plate can be adjusted, so that the exhaust is smoother and the oil smoke does not flow back into the heat dissipation chamber.

[0145] In addition, the present application also provides a range hood control method, such as Fig. 9 As shown, the following steps are included:

[0146] S1, the range hood power is turned on;

[0147] S2, determining whether the range hood is in cooling mode;

[0148] If not, proceed to step S3;

[0149] If yes, go to step S4;

[0150] S3, control the air guide plate to close the vent, and the range hood module is only used to absorb and exhaust oil smoke;

[0151] S4, detecting the rotation speed of the centrifugal fan of the range hood module; then finding the best fixed position of the air guide plate under the rotation speed of the centrifugal fan so that the heat dissipation fan blows out hot air without backflow and exhausts air smoothly.

[0152] The specific process of finding the optimal fixing position of the air guide plate under the rotation speed of the centrifugal fan so that the heat dissipation fan blows out hot air without backflow and exhausts air smoothly includes:

[0153] S40, after the air guide push-out plate is controlled to be retracted to a preset length (the vent is opened), the air guide rotating plate is controlled to start rotating within a certain range, and the speed of the cooling fan at different angles is recorded at the same time; wherein, the preset length is obtained through the test before leaving the factory, and the air guide plate can be extended and retracted in a large range of lengths, so the air guide plate length range corresponding to the minimum speed of the cooling fan is reduced in advance through the test, and the middle value in the reduced air guide plate length range is used as the preset length, so that the user can quickly determine the optimal length when using it. When determining the rotation angle, first use the middle value of the length range obtained by the test as the preset length. After the optimal rotation angle is determined, when the optimal length is determined later, the optimal rotation angle is kept unchanged.

[0154] S41, detecting the angle value corresponding to the minimum speed of the cooling fan within the angle range;

[0155] S42, controlling the air guide plate 33 to rotate to the angle and then stop rotating;

[0156] S43, controlling the air guide and ejection plate to extend and retract within a certain length range, and recording the speed of the cooling fan at different lengths;

[0157] S44, detecting a length value corresponding to the minimum speed of the cooling fan within the length range;

[0158] S45, controlling the air guide plate to stop extending after it reaches the specified length;

[0159] The fixed position of the air guide plate determined through steps S40-S45 is the optimal exhaust position.

[0160] In the above embodiment, a movable air guide module is provided at the vent 114, so that when the range hood is in the mode of only sucking and exhausting oil smoke, the air guide plate can be extended to close the vent; in the cooling mode, the heat of the condenser needs to be sucked into the fan cavity through the vent and discharged. Therefore, in the cooling mode, the air guide plate shrinks to a preset length and then starts to rotate within the working range, wherein the range value of the preset length is 0.4L-0.6L. The angle at which the air guide plate closes the vent is 0°, and the rotation angle range of the air guide plate is ±45°. At the same time, the speed of the heat dissipation fan at different angles is recorded, and within the rotation range angle, according to the angle corresponding to the minimum speed of the heat dissipation fan detected, the air guide plate is rotated to the angle and then stops rotating; at this angle, the air guide plate begins to extend and retract within the working range, and at the same time, the speed of the heat dissipation fan at different lengths is recorded, and the total length of the air guide plate closing the vent is L, and the length range of the air guide plate extension is 0.3LL. According to the length value corresponding to the minimum speed of the heat dissipation fan detected, the air guide plate is fixed at the length and then stops extending and retracting. When the air guide plate is fixed at this angle and extended to this length, it is the best exhaust position for the cooling fan.

[0161] If the speed of the cooling fan is detected and recorded one by one when the air guide plate is at different angles and different lengths, the large number of detection data will cause a long running time. The reason for adopting the above control process is that: after analysis, the air inlet angle of the cooling fan entering the centrifugal fan is an important influencing factor. There is an angle a between the air flow of the cooling fan outlet and the air flow inside the smoke fan duct. In theory, the two air flows are in the same direction and the smaller the angle a is, the smaller the impact between the cooling air flow and the air flow inside the fan is, and the smaller the resistance to cooling exhaust is. Therefore, the angle of the air guide plate directly affects whether the cooling fan exhausts smoothly, and is the main factor affecting exhaust. The length of the air guide plate also affects the air outlet direction and air volume of the cooling fan. The smaller the air guide plate is, the worse the cooling air outlet diversion effect is, but the larger the cooling fan air volume is; the longer the air guide plate is, the better the cooling air outlet diversion effect is, but the cooling fan air volume is smaller. Therefore, it is necessary to find a suitable length to minimize the exhaust resistance and minimize the demand for the cooling fan speed.

[0162] In order to solve the technical problem of oil smoke backflowing into the heat dissipation air cavity of the condenser during the hot air discharge of the condenser, the present application scheme adopts a retractable and rotatable air guide plate. In the oil smoke suction only mode, the air guide plate is extended to cover the vent; in the cooling mode, the air guide plate first rotates within the working range, and the rotation speed of the heat dissipation fan at different angles is recorded. When the angle with the smallest rotation speed is the optimal angle, and the air guide plate is fixed to the optimal angle, it is the optimal exhaust position; thereafter, the air guide plate is retracted and extended within the working range, and the rotation speed of the heat dissipation fan at different lengths is recorded. When the length with the smallest rotation speed is the optimal length, and the air guide plate is fixed to the optimal length, it is the optimal exhaust position. When the air guide plate is fixed at the optimal angle and the optimal length, the hot air from the condenser is sucked into the range hood module through the vent and discharged, so that the hot air pressure blown out of the heat dissipation cavity of the condenser is greater than the wind pressure in the fan cavity of the range hood, thereby achieving the technical effect that oil smoke will not backflow into the hot air cavity of the condenser and pollute the condenser. At the same time, during the driving process, this solution can adjust the fixed position of the air guide plate to the optimal exhaust position in real time according to the use environment, which can more flexibly respond to actual use conditions and ensure that oil smoke will not flow back every time it is used. It is more humane and intelligent, which improves the efficiency of the whole machine and extends the service life of the whole machine.

The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more range hood control device embodiments provided below can refer to the limitations of the range hood control method above, and will not be repeated here.
