Description
Technical Field
[0001] This invention relates to the field of household appliance technology, and in particular to a control method and a fume treatment device. Background Technology
[0002] Because kitchen spaces are generally small and cooking generates a lot of heat, the user experience is poor in summer or hot and humid weather. Some existing range hoods have a cooling function, such as... Figure 1 As shown, the range hood includes a refrigeration module 20 and a smoke extraction module 10. The smoke extraction module 10 has a smoke collection chamber 101, in which an exhaust fan 11 is installed. When the exhaust fan 11 is turned on, it creates a negative pressure in the smoke collection chamber 101, drawing smoke from the smoke inlet 102 into the smoke collection chamber 101 and expelling it outdoors from the smoke outlet 103. The refrigeration module 20 includes a refrigeration component 21 and a heat dissipation component 22. The refrigeration component 21 is located in the refrigeration chamber 201, which has a refrigeration return air inlet 202 and a refrigeration air outlet 203. The refrigeration component 21 is used to draw in air from the refrigeration return air inlet 202, cool it, and then deliver it to the refrigeration air outlet 203. The heat dissipation component 22 is located in the heat dissipation chamber 204, which has a heat dissipation return air inlet 205 and a heat dissipation air outlet 206. The heat dissipation component 22 is used to guide air into the heat dissipation return air inlet 205 and out through the heat dissipation air outlet 206 to remove heat from the heat dissipation chamber 204.
[0003] When the range hood is installed in the kitchen, both the cooling return air vent 202 of the cooling chamber 201 and the heat dissipation return air vent 205 of the heat dissipation chamber 204 are connected to the space above the kitchen ceiling. When the cooling module 20 is in the on state, both the cooling return air vent 202 and the heat dissipation return air vent 205 draw air from the ceiling space. Because the cooling return air vent 202 and the heat dissipation return air vent 205 are close together and the heat dissipation component 22 has stronger suction, air snatching can easily occur, resulting in less return air to the cooling chamber 201 and reducing the cooling effect. Summary of the Invention
[0004] This invention provides a control method and an oil fume treatment device to solve the technical problem in the prior art where the cooling chamber and heat dissipation chamber compete for air during the operation of the refrigeration module, resulting in poor cooling effect.
[0005] Based on the above concept, the technical solution adopted by this invention is as follows: A method for controlling an oil fume treatment device includes: When the cooling module is turned on, the current indoor temperature is obtained in real time; If the current indoor temperature is less than or equal to the first set temperature value, obtain the cooling return air parameters of the cooling chamber. If the cooling return air parameters meet the first cooling return air condition, turn on the fresh air module to supply air to the cooling chamber. If the current indoor temperature is greater than the first set temperature value, obtain the heat dissipation return air parameters of the heat dissipation cavity. If the heat dissipation return air parameters meet the first heat dissipation return air conditions, turn on the fresh air module to supply air to the heat dissipation cavity. During the fresh air module's air supply process, the airflow rate of the fresh air module is adjusted according to the cooling return air parameters and / or heat dissipation return air parameters.
[0006] Preferably, during the process of the fresh air module supplying air to the cooling chamber, the difference between the current indoor temperature and the set indoor temperature is recorded as the first difference. If the first difference is less than or equal to the first set difference, it is determined whether the cooling return air parameters meet the second cooling return air conditions. If they do, the air speed of the fresh air module is reduced; otherwise, the current air speed of the fresh air module is kept unchanged.
[0007] Preferably, during the process of supplying air to the cooling chamber from the fresh air module, if the cooling return air parameters meet the third cooling return air condition, the current air speed of the fresh air module is kept unchanged; otherwise, it is determined whether the air speed of the fresh air module is the maximum air speed. If it is the maximum air speed, the current air speed of the fresh air module is kept unchanged; if it is not the maximum air speed, the air speed of the fresh air module is increased.
[0008] Preferably, during the process of supplying air to the cooling chamber from the fresh air module, if the heat dissipation return air parameters meet the second heat dissipation return air condition, the air velocity of the fresh air module is reduced; after reducing the air velocity of the fresh air module, it is determined whether the cooling return air parameters meet the fourth cooling return air condition. If yes, the current air velocity of the fresh air module is maintained unchanged; if not, the air velocity of the fresh air module is increased.
[0009] Preferably, during the process of supplying air to the heat dissipation cavity from the fresh air module, the air speed of the fresh air module is adjusted according to the heat dissipation return air parameters, and the air supply volume of the fresh air module to the cooling cavity and the heat dissipation cavity is adjusted according to the cooling return air parameters.
[0010] Preferably, if the heat dissipation return air parameters meet the fifth heat dissipation return air condition, the current air velocity of the fresh air module remains unchanged; otherwise, the air velocity of the fresh air module is increased.
[0011] Preferably, when the cooling module is on, the outdoor environmental parameters are acquired in real time, and it is determined whether the stove is in cooking mode. If the outdoor environmental parameters meet the first outdoor condition and the stove is in cooking mode, the fresh air module is turned on, and the fresh air module is controlled to supply air to the cooling cavity or the heat dissipation cavity according to the setting of the smoke extraction module.
[0012] Preferably, when the cooling module is off, if the stove is in cooking mode, the speed of the fresh air module and the air supply fan of the cooling component are adjusted according to the speed of the smoke extraction module; if the stove is not in cooking mode, the start / stop and speed of the smoke extraction module, fresh air module and air supply fan are controlled according to the current outdoor temperature, current indoor temperature and indoor air quality level.
[0013] Preferably, the settings of the fresh air module and the supply air fan are adjusted according to the setting of the smoke extraction module, including: if the smoke extraction module is at a low setting, the supply air fan is at a medium setting; if the smoke extraction module is at a medium setting, the supply air fan is at a high setting; if the smoke extraction module is at a high setting, the supply air fan is at a high setting, and the fresh air module is at a high setting.
[0014] Preferably, when the cooling module is off and the stove is not cooking, if the current outdoor temperature is greater than or equal to the third set temperature value and less than or equal to the current indoor temperature, the start / stop and speed of the smoke extraction module, fresh air module and air supply fan are controlled according to the air quality level; if the current outdoor temperature is less than the third set temperature value and the current indoor temperature is greater than the third set temperature value, the start / stop and speed of the smoke extraction module are controlled according to the air quality level.
[0015] An oil fume treatment device, employing the control method for an oil fume treatment device as described above, the oil fume treatment device comprising: A smoking module has a smoke collection chamber and a smoke inlet and a smoke outlet communicating with the smoke collection chamber; A refrigeration module includes a refrigeration component and a heat dissipation component. The refrigeration component is disposed in a refrigeration chamber, which has a refrigeration return air inlet and a refrigeration air outlet. The refrigeration component is used to draw in air from the refrigeration return air inlet, cool it, and then deliver it to the refrigeration air outlet. The return air parameter of the refrigeration chamber is the same as the airflow parameter of the refrigeration return air inlet. The heat dissipation component is disposed in a heat dissipation chamber, which has a heat dissipation return air inlet and a heat dissipation air outlet. The heat dissipation component is used to guide air into the heat dissipation return air inlet and exhaust it from the heat dissipation air outlet to remove heat from the heat dissipation chamber. The return air parameter of the heat dissipation chamber is the same as the airflow parameter of the heat dissipation return air inlet. The fresh air module has an air inlet, a cooling air supply inlet, and a heat dissipation air supply inlet. The cooling air supply inlet is selectively connected to the cooling chamber through a cooling valve, and the heat dissipation air supply inlet is selectively connected to the heat dissipation chamber through a heat dissipation valve. The fresh air module is used to draw in outside air from the air inlet, filter it, and then send it into the cooling chamber through the cooling air supply inlet and / or into the heat dissipation chamber through the heat dissipation air supply inlet.
[0016] The beneficial effects of this invention are: The control method for the fume treatment device proposed in this invention acquires the current indoor temperature in real time when the refrigeration module is in the on state; if the current indoor temperature is less than or equal to a first set temperature value, the refrigeration return air parameters of the refrigeration chamber are acquired; if the refrigeration return air parameters meet the first refrigeration return air condition, the fresh air module is activated to supply air to the refrigeration chamber; if the current indoor temperature is greater than the first set temperature value, the heat dissipation return air parameters of the heat dissipation chamber are acquired; if the heat dissipation return air parameters meet the first heat dissipation return air condition, the fresh air module is activated to supply air to the heat dissipation chamber; during the air supply process of the fresh air module, the airflow of the fresh air module is adjusted according to the refrigeration return air parameters and / or the heat dissipation return air parameters. By setting up a fresh air module, air can be supplied to the cooling chamber and / or heat dissipation chamber to balance the return air volume of the cooling chamber and heat dissipation chamber, ensuring sufficient return air volume in the cooling chamber to guarantee the cooling effect without affecting the heat dissipation efficiency. By acquiring the current indoor temperature parameter and combining it with the cooling return air parameters and heat dissipation return air parameters, the fan speed of the fresh air module 30 is adjusted to better adapt to the current operating conditions, ensuring sufficient return air in the cooling chamber while maintaining the heat dissipation efficiency of the heat dissipation chamber. If the current indoor temperature is less than or equal to the first set temperature value, it indicates that the current indoor temperature is not high and the indoor load is medium or low, so air is supplied to the cooling chamber first to ensure the cooling effect. If the current indoor temperature is greater than the first set temperature value, it indicates that the current indoor temperature is high, the heat dissipation pressure of the heat dissipation chamber is high, and the heat dissipation effect is poor. By supplying air to the heat dissipation chamber, the heat dissipation efficiency can be maintained. Attached Figure Description

Detailed Implementation
[0019] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0020] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0021] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0023] Existing range hoods with cooling functions, such as Figure 1 As shown, the cooling return air vent 202 of the cooling chamber 201 and the heat dissipation return air vent 205 of the heat dissipation chamber 204 are both connected to the space above the kitchen ceiling. When the cooling module 20 is in the on state, both the cooling return air vent 202 and the heat dissipation return air vent 205 draw air from the ceiling space. Because the cooling return air vent 202 and the heat dissipation return air vent 205 are close to each other and the heat dissipation component 22 has a stronger suction, air snatching can easily occur, resulting in less return air to the cooling chamber 201 and reducing the cooling effect.
[0024] The refrigeration component 21 draws in air from the refrigeration return air inlet 202, cools it, and then delivers it to the refrigeration outlet 203. The refrigeration outlet 203 is connected to the indoor kitchen and is typically used for kitchen refrigeration to improve user comfort. To ensure air cleanliness, the refrigeration return air inlet 202 is usually equipped with multiple layers of filters. The filters increase the resistance to return air, resulting in reduced return airflow from the refrigeration chamber 201 and increased noise. Meanwhile, the heat dissipation return air inlet 205 of the heat dissipation chamber 204 only has a single-layer safety grille, which has lower resistance and facilitates return airflow, further exacerbating the airflow interception phenomenon.
[0025] See Figures 2 to 5 This embodiment provides an oil fume treatment device, including a smoke extraction module 10, a cooling module 20, and a fresh air module 30. The smoke extraction module 10 has a smoke collection chamber 101 and a smoke inlet 102 and a smoke outlet 103 communicating with the smoke collection chamber 101. The cooling module 20 includes a cooling component 21 and a heat dissipation component 22. The cooling component 21 is disposed in the cooling chamber 201, which has a cooling return air inlet 202 and a cooling air outlet 203. The cooling component 21 is used to draw in air from the cooling return air inlet 202, cool it, and then deliver it to the cooling air outlet 203. The heat dissipation component 22 is disposed in a heat dissipation chamber 204, which has a heat dissipation return air inlet 205 and a heat dissipation outlet 206. The heat dissipation outlet 206 and the heat dissipation component 22 are used to guide air into the heat dissipation return air inlet 205 and exhaust it from the heat dissipation outlet 206 to remove the heat from the heat dissipation cavity 204; the fresh air module 30 has an air inlet 301, a cooling air supply inlet 302 and a heat dissipation air supply inlet 303. The cooling air supply inlet 302 is selectively connected to the cooling cavity 201 through a cooling valve 31, and the heat dissipation air supply inlet 303 is selectively connected to the heat dissipation cavity 204 through a heat dissipation valve 32. The fresh air module 30 is used to draw in outside air from the air inlet 301, filter it, and then send it into the cooling cavity 201 through the cooling air supply inlet 302 and / or into the heat dissipation cavity 204 through the heat dissipation air supply inlet 303.
[0026] By setting up a fresh air module 30 and using a cooling valve 31 and a heat dissipation valve 32, the fresh air module 30 can supply air to the cooling chamber 201 and the heat dissipation chamber 204 individually, or supply air to the cooling chamber 201 and the heat dissipation chamber 204 simultaneously. This prevents insufficient return air from the cooling chamber 201. By supplying air, the return air volume of the cooling chamber 201 and the heat dissipation chamber 204 can be balanced, ensuring that the cooling chamber 201 receives sufficient return air to guarantee the cooling effect, without affecting the heat dissipation efficiency of the heat dissipation chamber 204.
[0027] The fume treatment device can be a side-draft range hood, a top-mounted range hood, a European-style range hood, an integrated stove, etc. All devices capable of treating fumes are within the protection scope of this optional embodiment.
[0028] The smoke extraction module 10 also includes a smoke exhaust fan 11, which is located inside the smoke collection chamber 101. When the smoke extraction module 10 is turned on, the smoke exhaust fan 11 is turned on, creating a negative pressure in the smoke collection chamber 101 to draw smoke from the smoke inlet 102 into the smoke collection chamber 101 and exhaust it outdoors from the smoke outlet 103. The smoke outlet 103 is connected to the outdoor atmosphere.
[0029] Taking the fume extraction module 10 as a reference, the vertical, horizontal, and front-back directions are defined. The cooling component 21 and the heat dissipation component 22 are distributed on the left and right sides of the fume extraction module 10, making one side of the fume extraction module 10 a cold zone and the other side a hot zone. This ensures a compact structure and separates the hot and cold zones to prevent mutual interference between cooling and heat dissipation. The front side of the fume extraction module 10 typically houses an operation panel and other components for easy operation of the fume treatment equipment, such as turning it on and off. The fresh air module 30 can be located on top of the fume extraction module 10, or on top of the cooling component 21 or the heat dissipation component 22. Alternatively, some of the fresh air modules 30 can be located on top of the fume extraction module 10, and some can be located on top of the cooling component 21.
[0030] The refrigeration module 20 can employ existing refrigeration structures, such as compressor refrigeration systems or semiconductor refrigeration structures. Exemplarily, the refrigeration component 21 includes an evaporator 211, the heat dissipation component 22 includes a condenser 221, and the refrigeration module 20 also includes a compressor 23 and a throttling device. Along the refrigerant flow direction, the compressor 23, condenser 221, throttling device, and evaporator 211 are sequentially connected. The compressor 23 compresses the refrigerant into high-temperature, high-pressure vapor and delivers it to the condenser 221. The condenser 221 condenses the refrigerant to form a high-temperature, medium-pressure liquid, which then passes through the throttling device to form a low-temperature, low-pressure gas-liquid mixture. The evaporator 211 evaporates the refrigerant to form low-temperature, low-pressure vapor, which is then delivered to the compressor 23 for further compression. The refrigeration principle is existing technology and will not be elaborated further here. The compressor 23 can be located in the refrigeration chamber 201 or the heat dissipation chamber 204; no limitation is made here.
[0031] The refrigeration assembly 21 also includes a blower 212, which draws in air from the refrigeration return air inlet 202 and delivers it to the refrigeration outlet 203. As the air flows within the refrigeration chamber 201, it comes into contact with the evaporator 211, thereby cooling the air. The heat dissipation assembly 22 also includes an exhaust fan 222, which draws in air from the heat dissipation return air inlet 205 and delivers it to the heat dissipation outlet 206. As the air flows within the heat dissipation chamber 204, it comes into contact with the condenser 221, thereby dissipating heat from the condenser 221.
[0032] The cooling air outlet 203 extends vertically to prevent the air from blowing directly onto the stove below the smoke extraction module 10, thus avoiding interference with the flame and potential safety risks. It also prevents the air from scattering the oil fumes near the smoke extraction module 10 or even blowing them onto the user, which would reduce the effectiveness of smoke extraction. Furthermore, it prevents the cooling air outlet 203 from being too close to the smoke extraction module 10, as this would make it easier for the user to absorb the cold air while cooking, resulting in a poorer cooling effect.
[0033] The fresh air module 30 includes a fresh air housing 33, a fresh air fan 34, and a fresh air filter 35. An air inlet 301, a cooling air supply inlet 302, and a heat dissipation air supply inlet 303 are all located within the fresh air housing 33. The fresh air fan 34 draws in outside air through the air inlet 301, filters it through the fresh air filter 35, and then delivers it to the cooling air supply inlet 302 and / or the heat dissipation air supply inlet 303. The air inlet 301 is connected to the outdoor atmosphere. When the cooling valve 31 is open, the cooling air supply inlet 302 is connected to the cooling chamber 201; when the cooling valve 31 is closed, the cooling air supply inlet 302 is isolated from the cooling chamber 201. The opening degree of the cooling valve 31 is adjustable. When the heat dissipation valve 32 is open, the heat dissipation air supply inlet 303 is connected to the heat dissipation chamber 204; when the heat dissipation valve 32 is closed, the heat dissipation air supply inlet 303 is isolated from the heat dissipation chamber 204. The opening degree of the heat dissipation valve 32 is adjustable.
[0034] A return air valve 24 is installed at the cooling return air inlet 202. When the cooling module 20 is in the closed state, the cooling return air inlet 202 does not require return air. If the fresh air module 30 is turned on at this time, the return air valve 24 is closed to prevent leakage of air supplied by the fresh air module 30 to the cooling chamber 201. When the cooling module 20 is in the closed state, the air supply fan 212 of the cooling component 21 can be turned on separately to supply air to the cooling outlet 203. At this time, the return air valve 24 and the cooling valve 31 can be turned on individually or simultaneously.
[0035] The fume treatment device also includes a controller. The fume extraction module 10, the cooling module 20, and the fresh air module 30 are all electrically connected to the controller. The controller can at least control the opening, closing, and speed settings of the exhaust fan 11, compressor 23, supply fan 212, exhaust fan 222, fresh air fan 34, and return air valve 24. The controller can at least control the opening degree of the cooling valve 31 and the heat dissipation valve 32. The control principle of the controller is existing technology and will not be described in detail here.
[0036] In some embodiments, the smoke extraction module 10 also includes an infrared temperature sensor, which can detect the temperature of the oil fumes and water vapor generated during cooking, and determine the amount of oil fumes and water vapor through existing experimentally verified algorithms. The controller can automatically adjust the speed of the smoke extraction module 10 according to the amount of oil fumes and water vapor.
[0037] See Figure 6 This embodiment provides a control method for an oil fume treatment device, and the oil fume treatment device adopts this control method. Besides the oil fume treatment device described above, other devices having a cooling module 20 and a fresh air module 30, or devices having a cooling module 20, a fresh air module 30, and a smoke extraction module 10, may also partially or completely adopt this control method.
[0038] The control method of the fume treatment device includes: when the refrigeration module 20 is in the on state, the current indoor temperature is acquired in real time; if the current indoor temperature is less than or equal to the first set temperature value, the refrigeration return air parameters of the refrigeration chamber 201 are acquired; if the refrigeration return air parameters meet the first refrigeration return air condition, the fresh air module 30 is turned on to supply air to the refrigeration chamber 201; if the current indoor temperature is greater than the first set temperature value, the heat dissipation return air parameters of the heat dissipation chamber 204 are acquired; if the heat dissipation return air parameters meet the first heat dissipation return air condition, the fresh air module 30 is turned on to supply air to the heat dissipation chamber 204.
[0039] By setting the fresh air module 30, air can be supplied to the cooling chamber 201 and / or the heat dissipation chamber 204 to balance the return air volume of the cooling chamber 201 and the heat dissipation chamber 204, ensuring sufficient return air volume in the cooling chamber 201 to guarantee the cooling effect without affecting the heat dissipation efficiency. By acquiring the current indoor temperature parameter and combining it with the cooling return air parameters and the heat dissipation return air parameters, sufficient return air in the cooling chamber 201 can be guaranteed while maintaining the heat dissipation efficiency of the heat dissipation chamber 204. If the current indoor temperature is less than or equal to the first set temperature value, it indicates that the current indoor temperature is not high and the indoor load is medium or low. Air is supplied to the cooling chamber 201 first to ensure the cooling effect. If the current indoor temperature is greater than the first set temperature value, it indicates that the current indoor temperature is high and the heat dissipation pressure of the heat dissipation chamber 204 is high, resulting in poor heat dissipation effect. Air is supplied to the heat dissipation chamber 204 to maintain the heat dissipation efficiency.
[0040] The first set temperature value can be set according to actual needs. For example, the first set temperature value is between 35℃ and 40℃. For example, the first set temperature value is 35℃, 36℃, 37℃, 38℃, 39℃, or 40℃. For example, if the current indoor temperature is less than or equal to 38℃, the cooling return air parameters of the cooling chamber 201 are obtained. If the cooling return air parameters meet the first cooling return air condition, the fresh air module 30 is activated to supply air to the cooling chamber 201. If the current indoor temperature is greater than 38℃, the heat dissipation return air parameters of the heat dissipation chamber 204 are obtained. If the heat dissipation return air parameters meet the first heat dissipation return air condition, the fresh air module 30 is activated to supply air to the heat dissipation chamber 204.
[0041] The cooling return air parameters of the cooling chamber 201, i.e., the airflow parameters at the cooling return air inlet 202 of the cooling chamber 201, are one or more parameters that may affect the cooling effect. Exemplarily, the cooling return air parameters of the cooling chamber 201 include cooling return air volume and / or cooling air pressure. In some embodiments, the cooling return air parameters of the cooling chamber 201 include cooling return air volume. In some embodiments, the cooling return air parameters of the cooling chamber 201 include cooling air pressure. In some embodiments, the cooling return air parameters of the cooling chamber 201 include both cooling return air volume and cooling air pressure. Typically, insufficient cooling return air volume leads to a decrease in the heat exchange area utilization rate of the evaporator 211, significantly impacting the cooling effect.
[0042] In this embodiment, the cooling return air parameter is described using the cooling return air volume as an example. Exemplarily, the cooling return air parameter satisfying the first cooling return air condition includes: the cooling return air volume is less than a1% of the rated cooling air volume. The value of a1 can be adjusted according to actual needs. Exemplarily, a1 is 75-80. Exemplarily, the cooling return air parameter satisfying the first cooling return air condition includes: the cooling return air volume is less than 80% of the rated cooling air volume. The rated cooling air volume can be determined based on the performance of the cooling component 21 and is not limited here.
[0043] The heat dissipation return air parameters of the heat dissipation cavity 204, i.e., the airflow parameters at the heat dissipation return air inlet 205 of the heat dissipation cavity 204, are one or more parameters that may affect the heat dissipation efficiency. For example, the heat dissipation return air parameters of the heat dissipation cavity 204 include the heat dissipation return air volume and the heat dissipation temperature. The heat dissipation return air parameters satisfying the first heat dissipation return air condition include: the heat dissipation return air volume is less than b1% of the rated heat dissipation air volume, and the heat dissipation temperature is greater than or equal to B1℃. The values of b1 and B1 can be adjusted according to actual needs. For example, b1 is 70-75℃, and B1 is 55-60℃. For example, the heat dissipation return air parameters satisfying the first heat dissipation return air condition include: the heat dissipation return air volume is less than 75% of the rated heat dissipation air volume, and the heat dissipation temperature is greater than or equal to 55℃. The rated heat dissipation air volume can be determined based on the performance of the heat dissipation component 22 and is not limited here.
[0044] The fume treatment device includes temperature sensors to acquire information such as the current indoor temperature and heat dissipation temperature; multiple temperature sensors can be installed. The device also includes an anemometer or micromanometer to acquire airflow or air pressure.
[0045] When the cooling module 20 is turned on, its purpose is to blow cool air into the kitchen to lower the indoor temperature. Typically, the control panel of the fume extraction device allows the user to manually set the desired temperature so that the kitchen temperature can be lowered to the user-set temperature after the cooling module 20 is turned on. The control panel is electrically connected to the controller, so the controller can receive the user-set temperature, which in this embodiment is denoted as the indoor set temperature.
[0046] The fresh air module 30 can supply air to the cooling chamber 201 independently, to the heat dissipation chamber 204 independently, or simultaneously to both. During the air supply process, the airflow rate of the fresh air module 30 is adjusted based on the cooling return air parameters and / or the heat dissipation return air parameters. By adjusting the airflow rate, the fresh air module 30 is better adapted to the current operating conditions, ensuring sufficient cooling return air while maintaining the heat dissipation efficiency of the heat dissipation chamber 204. After the fresh air module 30 is activated, its airflow rate gradually increases. During this process, the cooling return air parameters of the cooling chamber 201 and the heat dissipation return air parameters of the heat dissipation chamber 204 are acquired in real time, and the airflow rate of the fresh air module 30 is adjusted accordingly.
[0047] In some embodiments, see Figure 7 During the process of supplying air to the cooling chamber 201 by the fresh air module 30, before adjusting the air speed of the fresh air module 30, the difference between the current indoor temperature and the indoor set temperature is obtained and recorded as the first difference. If the first difference is less than or equal to the first set difference, the air speed of the fresh air module 30 is adjusted according to the cooling return air parameters.
[0048] For example, adjusting the airflow speed of the fresh air module 30 according to the cooling return air parameters includes: determining whether the cooling return air parameters meet the second cooling return air condition; if so, reducing the airflow speed of the fresh air module 30; otherwise, maintaining the current airflow speed of the fresh air module 30 unchanged. If the first difference is greater than the first set difference, the current airflow speed of the fresh air module 30 can be maintained unchanged.
[0049] Wherein, the first difference is less than or equal to the first set difference, that is, the current indoor temperature is close to the indoor set temperature, and the cooling demand is weak. In order to avoid excessive air supply leading to a low indoor temperature and to reduce energy consumption, the air velocity of the fresh air module 30 can be reduced. The magnitude of the first set difference can be set according to actual needs. For example, the first set difference is 1℃ or 2℃.
[0050] It is important to note that even reducing the fan speed of the fresh air module 30 should not result in an excessively low return air volume at the cooling return air vent 202. Therefore, before reducing the fan speed of the fresh air module 30, it is determined whether the cooling return air parameters meet the second cooling return air condition. If they do, the fan speed of the fresh air module 30 is reduced; otherwise, the current fan speed of the fresh air module 30 is maintained. Regardless of whether the fan speed is reduced or maintained, the difference between the current indoor temperature and the set indoor temperature is continuously acquired and recorded as the first difference, and the above process is repeated.
[0051] For example, the cooling return air parameters satisfying the second cooling return air condition include: the cooling return air volume is greater than or equal to a2% of the rated cooling air volume. The value of a2 can be adjusted according to actual needs. For example, a2 is 75-80. For example, the cooling return air parameters satisfying the second cooling return air condition include: the cooling return air volume is greater than or equal to 75% of the rated cooling air volume, ensuring that even if the air velocity of the fresh air module 30 is reduced, the return air volume at the cooling return air outlet 202 will not be too low.
[0052] In some embodiments, see Figure 8 During the process of supplying air to the cooling chamber 201 from the fresh air module 30, if the cooling return air parameters meet the third cooling return air condition, the current air velocity of the fresh air module 30 remains unchanged. For example, meeting the third cooling return air condition includes: the cooling return air volume is greater than or equal to a3% of the rated cooling air volume. Wherein, a3 is greater than a1, and the value of a3 can be adjusted according to actual needs. For example, a3 is 90-100. For example, meeting the third cooling return air condition also includes: the cooling return air volume is greater than or equal to 90% of the rated cooling air volume.
[0053] During the process of supplying air to the cooling chamber 201 from the fresh air module 30, it is determined whether the cooling return air parameters meet the third cooling return air condition. If not, it is determined whether the airflow speed of the fresh air module 30 is at its maximum speed. If it is at its maximum speed, the current airflow speed of the fresh air module 30 is maintained unchanged; if it is not at its maximum speed, the airflow speed of the fresh air module 30 is increased. When increasing the airflow speed of the fresh air module 30, the set value can be increased each time or the speed can be increased by one level each time.
[0054] In some embodiments, see Figure 9 During the process of supplying air to the cooling chamber 201 from the fresh air module 30, if the heat dissipation return air parameters meet the second heat dissipation return air condition, the air velocity of the fresh air module 30 is reduced. For example, meeting the second heat dissipation return air condition includes: the heat dissipation return air volume is less than or equal to b2% of the rated heat dissipation air volume. Wherein, b2 is less than or equal to b1, and the value of b2 can be adjusted according to actual needs. For example, b2 is 65-70. For example, meeting the second heat dissipation return air condition also includes: the heat dissipation return air volume is less than or equal to 70% of the rated heat dissipation air volume.
[0055] After reducing the airflow speed of the fresh air module 30, it is determined whether the cooling return air parameters meet the fourth cooling return air condition. If so, the current airflow speed of the fresh air module 30 remains unchanged; otherwise, the airflow speed of the fresh air module 30 is increased. Through continuous adjustment of the airflow speed of the fresh air module 30, the cooling return air parameters are made to meet the fourth cooling return air condition.
[0056] The fourth cooling return air condition requirement includes: the cooling return air volume is greater than or equal to a4% of the rated cooling air volume. Here, a4 is greater than a1, and the value of a4 can be adjusted according to actual needs. For example, a4 is 80-85. Another example is that the cooling return air volume is greater than or equal to 85% of the rated cooling air volume.
[0057] In some embodiments, during the process of the fresh air module 30 supplying air to the cooling chamber 201, if the cooling return air parameters meet the fifth cooling return air condition, the fresh air module 30 is controlled to operate at maximum wind speed until the cooling return air parameters meet the fourth cooling return air condition. For example, meeting the fifth cooling return air condition includes: the cooling return air volume is less than a5% of the rated cooling air volume. Wherein, a5 is less than a4. For example, a5 is 70-75. For example, meeting the fifth cooling return air condition also includes: the cooling return air volume is less than 70% of the rated cooling air volume.
[0058] During the operation of the fresh air module 30 at maximum wind speed, if the heat dissipation return air parameters meet the third heat dissipation return air condition, the fresh air module 30 is controlled to pause for a second period and then reduce its wind speed. For example, meeting the third heat dissipation return air condition includes: the heat dissipation return air volume is less than b3% of the rated heat dissipation air volume. Wherein, b3 is less than b1, b3 is less than b2, and the value of b3 can be adjusted according to actual needs. For example, b3 is 60-65. For example, meeting the third heat dissipation return air condition also includes: the heat dissipation return air volume is less than 60% of the rated heat dissipation air volume.
[0059] During the intermittent start-stop process of the fresh air module 30, the airflow speed of the fresh air module 30 can be 80% of its maximum speed. Through intermittent start-stop, the cooling return air parameters meet the sixth cooling return air condition. For example, meeting the sixth cooling return air condition includes: the cooling return air volume is greater than or equal to a6% of the rated cooling airflow. For example, a6 is 80-85. For example, meeting the sixth cooling return air condition also includes: the cooling return air volume is greater than or equal to 80% of the rated cooling airflow.
[0060] In some embodiments, during the process of supplying air to the heat dissipation cavity 204 from the fresh air module 30, the airflow rate of the fresh air module 30 is adjusted according to the heat dissipation return air parameters, and the airflow volume supplied by the fresh air module 30 to the cooling cavity 201 and the heat dissipation cavity 204 is adjusted according to the cooling return air parameters. By adjusting the airflow rate of the fresh air module 30, sufficient cooling return air is ensured while maintaining the heat dissipation efficiency of the heat dissipation cavity 204. After the fresh air module 30 is turned on, the airflow rate of the fresh air module 30 gradually increases. During this process, the cooling return air parameters of the cooling cavity 201 and the heat dissipation return air parameters of the heat dissipation cavity 204 are acquired in real time, and the airflow rate of the fresh air module 30 is adjusted according to the acquired parameters.
[0061] For example, during the process of supplying air to the heat dissipation cavity 204 by the fresh air module 30, the air speed of the fresh air module 30 is adjusted according to the heat dissipation return air parameters, including: if the heat dissipation return air parameters meet the fifth heat dissipation return air condition, then the current air speed of the fresh air module 30 is kept unchanged; otherwise, the air speed of the fresh air module 30 is increased.
[0062] The supply air volume of the fresh air module 30 to the cooling chamber 201 and the heat dissipation chamber 204 is adjusted according to the cooling return air parameters. This can be achieved by supplying 100% air to the heat dissipation chamber 204 and 0% air to the cooling chamber 201, i.e., supplying air only to the heat dissipation chamber 204; or by supplying air to both the heat dissipation chamber 204 and the cooling chamber 201 simultaneously, with the supply air volume allocated according to the cooling return air parameters. For example, after adjusting the airflow speed of the fresh air module 30 according to the heat dissipation return air parameters and maintaining the current airflow speed, if the cooling return air parameters meet the seventh heat dissipation return air condition, then the fresh air module 30 supplies air to both the cooling chamber 201 and the heat dissipation chamber 204 simultaneously.
[0063] For example, the heat dissipation return air parameters satisfying the fifth heat dissipation return air condition include: the heat dissipation return air volume is greater than or equal to b5% of the rated heat dissipation air volume, and the heat dissipation temperature is less than or equal to B5℃. The values of b5 and B5 can be adjusted according to actual needs. For example, b5 is 80-85, and B5 is 45-50. Alternatively, the heat dissipation return air parameters satisfying the fifth heat dissipation return air condition include: the heat dissipation return air volume is greater than or equal to 80% of the rated heat dissipation air volume, and the heat dissipation temperature is less than or equal to 50℃.
[0064] For example, the cooling return air parameters satisfying the seventh cooling return air condition include: the cooling return air volume is less than a7% of the rated cooling air volume. The value of a7 can be adjusted according to actual needs. For example, a7 is 70-75. For example, the cooling return air parameters satisfying the seventh cooling return air condition include: the cooling return air volume is less than 75% of the rated cooling air volume.
[0065] When the fresh air module 30 simultaneously supplies air to the cooling chamber 201 and the heat dissipation chamber 204, the supply air volume to the cooling chamber 201 and the heat dissipation chamber 204 can be allocated. For example, the total air volume of the fresh air module 30 is 100%, the cooling chamber 201 is allocated 70% of the total air volume, and the heat dissipation chamber 204 is allocated 30% of the total air volume. This can be achieved by adjusting the opening degree of the cooling valve 31 and the heat dissipation valve 32; the allocation ratio can be adjusted according to actual needs. The allocation ratio of the supply air volume to the cooling chamber 201 and the heat dissipation chamber 204 can be a fixed value or set according to the cooling return air parameters.
[0066] In summary, during the process of supplying air to the cooling chamber 201 and / or the heat dissipation chamber 204 through the fresh air module 30, priority is given to ensuring the cooling return air volume of the cooling return air vent 202, and then air is supplied to the heat dissipation chamber 204 as needed to prevent excessively low heat dissipation efficiency. When adjusting the fan speed of the fresh air module 30, whether increasing or decreasing, the set value can be changed each time, or it can be adjusted according to the set speed each time.
[0067] If the cooling return air parameters meet the third cooling return air condition and the heat dissipation return air parameters meet the fourth heat dissipation return air condition, the fresh air module 30 can be shut down after operating continuously for a first duration. Meeting the fourth heat dissipation return air condition includes: the heat dissipation return air volume being greater than or equal to b4% of the rated heat dissipation air volume. The value of b4 can be adjusted according to actual needs. For example, meeting the fourth heat dissipation return air condition includes: the heat dissipation return air volume being greater than or equal to 75% of the rated heat dissipation air volume. The first duration can be adjusted according to actual needs. For example, the first duration is 3 minutes.
[0068] In one specific embodiment, when the cooling module 20 is in the on state, the current indoor temperature is acquired in real time; if the current indoor temperature is less than or equal to 38°C, the cooling return air volume of the cooling chamber 201 is acquired; if the cooling return air volume is less than 80% of the rated cooling air volume, the fresh air module 30 is turned on to supply air to the cooling chamber 201; if the current indoor temperature is greater than 38°C, the heat dissipation return air volume and heat dissipation temperature of the heat dissipation chamber 204 are acquired; if the heat dissipation return air volume is less than 75% of the rated heat dissipation air volume and the heat dissipation temperature is greater than or equal to 55°C, the fresh air module 30 is turned on to supply air to the heat dissipation chamber 204.
[0069] Optionally, during the process of the fresh air module 30 supplying air to the cooling chamber 201, the difference between the current indoor temperature and the set indoor temperature is recorded as the first difference. If the first difference is less than or equal to 1℃, it is determined whether the cooling return air volume is greater than or equal to 75% of the rated cooling air volume. If so, the air speed of the fresh air module 30 is reduced; otherwise, the current air speed of the fresh air module 30 is kept unchanged.
[0070] Optionally, during the process of supplying air to the cooling chamber 201 from the fresh air module 30, if the cooling return air volume is greater than or equal to 90% of the rated cooling air volume, the current air velocity of the fresh air module 30 remains unchanged. If the heat dissipation return air volume is less than or equal to 70% of the rated heat dissipation air volume, the air velocity of the fresh air module 30 is reduced.
[0071] Optionally, during the process of supplying air to the cooling chamber 201 by the fresh air module 30, if the cooling return air volume is less than 70% of the rated cooling air volume, the fresh air module 30 is controlled to operate at its maximum fan speed until the cooling return air volume is greater than or equal to 85% of the rated cooling air volume. During the operation of the fresh air module 30 at its maximum fan speed, if the heat dissipation return air volume is less than 60% of the rated heat dissipation air volume, the fresh air module 30 is controlled to pause for 10 seconds and then operate at 80% of its maximum fan speed.
[0072] Optionally, during the process of supplying air from the fresh air module 30 to the heat dissipation cavity 204, if the heat dissipation return air volume is greater than or equal to 80% of the rated heat dissipation air volume and the heat dissipation temperature is less than or equal to 50℃, the current air velocity of the fresh air module 30 is maintained unchanged; otherwise, the air velocity of the fresh air module 30 is increased. After maintaining the current air velocity of the fresh air module 30, if the cooling return air volume is less than 75% of the rated cooling air volume, the fresh air module 30 supplies air to both the cooling cavity 201 and the heat dissipation cavity 204 simultaneously.
[0073] In some embodiments, see Figure 10 When the cooling module 20 is in the on state, the outdoor environmental parameters are obtained in real time, and it is determined whether the stove is in the cooking state. If the outdoor environmental parameters meet the first outdoor condition and the stove is in the cooking state, the fresh air module 30 is turned on, and the fresh air module 30 is controlled to supply air to the cooling cavity 201 or to the heat dissipation cavity 204 according to the setting of the smoke extraction module 10.
[0074] The outdoor environmental parameters include, but are not limited to, one or more of the following: outdoor temperature, outdoor humidity, outdoor air quality, and outdoor wind speed. For example, the outdoor environmental parameters include the current outdoor temperature. The outdoor environmental parameters satisfy a first outdoor condition, including: the current outdoor temperature is less than or equal to a second set temperature value. Where the current outdoor temperature is less than or equal to the second set temperature value, it indicates that the current outdoor temperature is not too high, and the outdoor air introduced through the fresh air module 30 will not significantly affect cooling and heat dissipation. If the current outdoor temperature is too high, introducing outdoor air through the fresh air module 30 into the cooling chamber 201 will cause the cold air temperature to rise, reducing the cooling effect; introducing outdoor air through the fresh air module 30 into the heat dissipation chamber 204 will cause the temperature of the heat dissipation chamber 204 to rise, which is detrimental to heat dissipation. The cooktop has a cooking state and a non-cooking state. The state of the cooktop can be obtained using current temperature sensors or image recognition technologies, which will not be elaborated upon here.
[0075] If the current outdoor temperature is greater than the second set temperature value, the fresh air module 30 can be turned off, or the fresh air module 30 can be controlled to operate according to other conditions. For example, if the current outdoor temperature is greater than the second set temperature value and the current indoor temperature is less than or equal to the first set temperature value, and the cooling return air parameters meet the first cooling return air condition, the fresh air module 30 is turned on to supply air to the cooling chamber 201.
[0076] The second set temperature value can be set according to actual needs. For example, the second set temperature value is between 28℃ and 35℃. For example, the second set temperature value is 28℃, 29℃, 30℃, 31℃, 32℃, 33℃, 34℃, or 35℃. For example, if the current outdoor temperature is less than or equal to 28℃ and the stove is in cooking mode, the fresh air module 30 is turned on, and the fresh air module 30 is controlled to supply air to the cooling chamber 201 or the heat dissipation chamber 204 according to the setting of the smoke extraction module 10.
[0077] The smoke extraction module 10 is typically set to a low, medium, or high setting, and this is not limited here. For example, controlling the fresh air module 30 to supply air to the cooling chamber 201 or the heat dissipation chamber 204 according to the setting of the smoke extraction module 10 includes: if the smoke extraction module 10 is at a low or medium setting, the fresh air module 30 supplies air to the heat dissipation chamber 204; if the smoke extraction module 10 is at a high setting, the fresh air module 30 supplies air to the cooling chamber 201.
[0078] When the smoke extraction module 10 is in a low or medium setting, it may be used for steaming, boiling, or stir-frying with minimal smoke. Air is supplied to the heat dissipation chamber 204 to improve heat dissipation efficiency. When the smoke extraction module 10 is in a high setting, it may be used for stir-frying, generating more heat and smoke. Air is supplied to the cooling chamber 201 to increase the volume of cooling return air and the cleanliness of the supply air. The cooling chamber 201 also lowers the temperature of the return air, ensuring a comfortable temperature for the user and clean breathing air. This also reduces the speed of the supply fan 212, lowering operating noise.
[0079] The smoke extraction module 10, the fresh air module 30, and the air supply fan 212 all have adjustable speeds. For example, each of these modules has a low, medium, and high speed, with different speeds corresponding to different settings. The speed of the smoke extraction module 10 can be automatically adjusted based on the temperature of the oil fume and water vapor obtained from an infrared temperature sensor. In other embodiments, the smoke extraction module 10, the fresh air module 30, and the air supply fan 212 can have even more speed settings.
[0080] In some embodiments, the refrigeration module 20 is in a closed state, the refrigeration chamber 201 does not require return air, and the heat dissipation chamber 204 does not require heat dissipation. Therefore, the return air valve 24 at the refrigeration return air inlet 202 can be closed, and the refrigeration valve 31 between the fresh air module 30 and the refrigeration assembly 21 can be opened to allow air intake using the supply air fan 212 of the fresh air module 30 or the refrigeration assembly 21. When the fresh air module 30 is turned on, it supplies air to the refrigeration chamber 201. Closing the return air valve 24 prevents the air supplied to the refrigeration chamber 201 from leaking through the refrigeration return air inlet 202. The purpose of turning on the supply air fan 212 is to deliver the air from the refrigeration chamber 201 to the kitchen through the refrigeration air outlet 203. Therefore, the supply air fan 212, in conjunction with the fresh air module 30, can improve the air delivery efficiency from the refrigeration chamber 201 to the kitchen. When the fresh air module 30 is closed, if the supply air fan 212 is turned on, the supply air fan 212 can draw in outside air through the air duct of the fresh air module 30 because the cooling valve 31 between the fresh air module 30 and the cooling component 21 is open. The power of the supply air fan 212 is greater than that of the fresh air fan 34 in the fresh air module 30. Therefore, when the fresh air module 30 is closed, turning on the supply air fan 212 can achieve a better ventilation effect. In other embodiments, the supply air fan 212 can draw in air by opening the return air valve 24.
[0081] like Figure 11 As shown, when the cooling module 20 is off, if the stove is in cooking mode, the speed of the fresh air module 30 and the air supply fan 212 is adjusted according to the speed of the smoke extraction module 10; if the stove is not in cooking mode, the start / stop and speed of the smoke extraction module 10, the fresh air module 30, and the air supply fan 212 are controlled according to the current outdoor temperature, the current indoor temperature, and the indoor air quality level. In non-cooling mode, the smoke extraction module 10, the fresh air module 30, and the air supply fan 212 work together to refresh the indoor air, improve air quality, and free up the user's hands. The air supply fan 212 increases the airflow, thereby improving air exchange efficiency.
[0082] If the outdoor temperature is low, turning on the fresh air module 30 or the air supply fan 212 will draw outside air into the room, potentially causing the indoor temperature to drop too low. Therefore, it is best to avoid turning on the fresh air module 30 or the air supply fan 212. If the stove is in the cooking state and there is a lot of heat in the room, even if the fresh air module 30 or the air supply fan 212 is turned on to introduce some cool air, it will not have a significant impact on the indoor temperature.
[0083] Indoor air quality can be detected using existing sensors such as PM2.5 and VOCs. Alternatively, other existing detection technologies can be employed. Air quality levels can be categorized as excellent, good, moderate, and poor, as needed. In other embodiments, air quality levels can be further subdivided.
[0084] For example, when the cooling module 20 is in the off state and the stove is in the cooking state, the speed of the fresh air module 30 and the air supply fan 212 is adjusted according to the speed of the smoke extraction module 10. This adjustment includes: if the smoke extraction module 10 is at a low speed, the air supply fan 212 is at a medium speed; if the smoke extraction module 10 is at a medium speed, the air supply fan 212 is at a high speed; if the smoke extraction module 10 is at a high speed, the air supply fan 212 is at a high speed, and the fresh air module 30 is at a high speed.
[0085] For example, when the cooling module 20 is in the off state and the stove is in the non-cooking state, if the current outdoor temperature is greater than or equal to the third set temperature value and less than or equal to the current indoor temperature, the start / stop and speed of the smoke extraction module 10, the fresh air module 30 and the air supply fan 212 are controlled according to the air quality level; if the current outdoor temperature is less than the third set temperature value and the current indoor temperature is greater than the third set temperature value, the start / stop and speed of the smoke extraction module 10 are controlled according to the air quality level.
[0086] If the current outdoor temperature is greater than or equal to the third set temperature value, it means that the outside temperature is not too low, so the fresh air module 30 and the air supply fan 212 can be turned on. If the current outdoor temperature is less than or equal to the third set temperature value, it means that the outside temperature is too low, so the fresh air module 30 and the air supply fan 212 should not be turned on to prevent cold air from entering the room and causing discomfort.
[0087] The third set temperature value can be set according to actual needs. For example, the third set temperature value is between 8℃ and 12℃. For example, the third set temperature value can be 8℃, 9℃, 10℃, 11℃, or 12℃. For example, if the current outdoor temperature is greater than or equal to 10℃ and less than or equal to the current indoor temperature, the start / stop and speed of the smoke extraction module 10, the fresh air module 30, and the air supply fan 212 are controlled according to the air quality level; if the current outdoor temperature is less than 10℃ and the current indoor temperature is greater than 10℃, the start / stop and speed of the smoke extraction module 10 are controlled according to the air quality level.
[0088] For example, when the current outdoor temperature is greater than or equal to a third set temperature value and less than or equal to the current indoor temperature, if the indoor air quality level is excellent, the smoke extraction module 10, the fresh air module 30, and the supply air fan 212 are all in the off state; if the indoor air quality level is good, the smoke extraction module 10 is at a low setting, and the fresh air fan 34 is at a low setting; if the indoor air quality level is moderate, the smoke extraction module 10 is at a medium setting, and the fresh air fan 34 is at a medium setting; if the indoor air quality level is poor, the smoke extraction module 10 is at a high setting, and the supply air fan 212 is at a low, medium, or high setting. Alternatively, if the indoor air quality level is poor, the smoke extraction module 10 is at a high setting, the supply air fan 212 is at a low setting, and the fresh air module 30 is at a high setting.
[0089] For example, when the current outdoor temperature is lower than the third set temperature value and the current indoor temperature is higher than the third set temperature value, if the indoor air quality level is excellent, the smoke extraction module 10, the fresh air module 30, and the air supply fan 212 are all in the off state; if the indoor air quality level is good, the smoke extraction module 10 is in the low setting; if the indoor air quality level is medium, the smoke extraction module 10 is in the medium setting; if the indoor air quality level is poor, the smoke extraction module 10 is in the high setting.
