[0002] Integrated stoves are kitchen appliances that integrate functions such as smoke exhaust, stoves, and tableware disinfection, and are widely used in daily life. At present, some integrated stoves are integrated with air conditioning modules to adjust the temperature of the indoor environment.

[0003] However, when the integrated stove uses the air-conditioning module to adjust the indoor temperature, if the temperature of the heat exchange with the evaporator in the air-conditioning module is too low, it is easy to cause frost on the heat exchanger in the air-conditioning module.

[0047] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0048] The main solution of an embodiment of the present invention is: based on an integrated stove including an air-conditioning module and a smoke exhaust module, an operation mode of the integrated stove is obtained; when the operation mode is a defrost mode, the smoke exhaust module is controlled to blow the inhaled indoor smoke to a target heat exchanger in the air-conditioning module to defrost the target heat exchanger.

[0049] Due to the prior art, currently, during the use of the integrated stove, the kitchen environment temperature cannot be adjusted, and the kitchen temperature is easily too high or too low, affecting the comfort of indoor users.

[0050] The present invention provides the above-mentioned solution, aiming to realize the frost of the air-conditioning module in the integrated stove, and ensure the heat exchange effect of the air-conditioning module on the indoor environment.

[0051] In an embodiment of the present invention, an integrated stove is provided. The integrated stove is specifically an integrated device that integrates a cooking module (such as a stove 2, a microwave oven and / or an oven, etc.) and other kitchen appliance functional modules (such as a smoke exhaust module 3, a tableware disinfection module, a tableware drying module and / or a purification module, etc.).

[0052] In this embodiment, refer to Figure 1 The integrated stove includes a housing 1, a stove top 2, a smoke exhaust module 3, an air conditioning module 4, etc. The stove top 2, the smoke exhaust module 3, and the air conditioning module 4 are integrated and installed on the housing 1. The housing 1 is provided with at least two separated installation cavities, and the smoke exhaust module 3 and the air conditioning module 4 are respectively installed in different installation cavities. The air flow channel of the smoke exhaust module 3 and the air flow channel in the air conditioning module 4 can be isolated from each other, or a vent can be provided, and a bypass valve is provided at the vent to connect or cut off the two air flow channels according to actual control requirements.

[0053] The stove 2 is specifically used for installing a stove, which can be a module integrated on an integrated stove, or can be installed by the user based on his own needs.

[0054] The smoke exhaust module 3 is specifically used to exhaust the indoor oil smoke to the outside (i.e., exhaust the smoke from the room). The housing 1 is provided with an indoor smoke exhaust port and a smoke outlet. The smoke exhaust module 3 includes a smoke exhaust duct and a smoke exhaust fan arranged in the smoke exhaust duct. The smoke exhaust duct is connected to the indoor smoke exhaust port and the smoke outlet. The smoke outlet can be directly connected to the outdoor environment, can also be connected to the oil smoke purification device, can also be connected to the exhaust duct of the air conditioning module 4, and so on. The number of indoor smoke exhaust ports can be one or more than one.

[0055] In this embodiment, the smoke exhaust fan is a fan with different speed gears. When the smoke exhaust fan is running at different speed gears, the running wind gears of the smoke exhaust fan are different, and the amount of oil smoke inhaled from the indoor air per unit time by the smoke exhaust module 3 is different. The larger the speed gear of the smoke exhaust fan, the larger its running wind gear, and the greater the amount of oil smoke inhaled per unit time; vice versa. In other embodiments, the smoke exhaust fan may also be a fixed speed fan.

[0056] The indoor smoke exhaust port of the smoke exhaust module 3 may be provided with a smoke exhaust valve or a guide member, which is used to control the opening or closing of the indoor smoke exhaust port. Further, the opening of the smoke exhaust valve is adjustable or the position of the guide member is adjustable, and the amount of air inhaled from the indoor environment by the smoke exhaust module 3 is different under different openings or different guide positions.

[0057] The air conditioning module 4 is specifically used to adjust the indoor temperature. The air conditioning module 4 includes a refrigerant circulation loop, and the refrigerant circulation loop includes a compressor, a first heat exchanger, a throttling device, and a second heat exchanger connected in sequence. An isolated first air cavity and a second air cavity are provided in the installation space of the air conditioning module 4 in the shell 1. The shell 1 is provided with an air outlet and a return air outlet connected to the first air cavity, and an air inlet and an exhaust port connected to the second air cavity. The number of the air outlet, the return air outlet, the exhaust port and / or the air inlet can be one or more than one. In this embodiment, the indoor smoke exhaust port of the smoke exhaust module 3 is arranged above the air outlet of the air conditioning module 4.

[0058] In this embodiment, the housing 1 is further provided with a fresh air inlet connected to the first air cavity, and outdoor air can enter the first air cavity from the fresh air inlet. The return air port and the fresh air inlet can be provided with valves to control their opening or closing.

[0059] The first heat exchanger is arranged in the first air cavity, and an air supply fan is arranged in the first air cavity. When the air supply fan is in operation, the air supply fan drives the indoor air from the return air port and / or the fresh air inlet into the first air cavity, and the air is sent into the indoor environment from the air outlet after heat exchange in the first heat exchanger. In this embodiment, the air supply fan is a fan with different speed gears. When the air supply fan is operated at different speed gears, the air conditioning module 4 has different air outlet gears, and the air volume sent into the indoor environment by the air conditioning module 4 per unit time is different. The larger the speed gear, the larger the air outlet gear of the air conditioning module 4, and the larger the amount of oil smoke inhaled by the air conditioning module 4 per unit time; and vice versa. In other embodiments, the air supply fan may also be a fixed speed fan.

[0060] The second heat exchanger is arranged in the second air cavity, and an exhaust fan is arranged in the second air cavity. When the exhaust fan is running, the exhaust fan drives the external air to enter the second air cavity from the air inlet, and the air is discharged to the outdoor environment from the exhaust port after heat exchange in the second heat exchanger. The second air cavity and the exhaust port can be connected through an exhaust duct. The exhaust port here and the smoke outlet in the above-mentioned smoke exhaust module 3 can be a common air port.

[0061] The air outlet of the air conditioning module 4 may be provided with an air guide member. When the air guide member operates at different air guide positions, the air outlet direction and / or air volume of the air outlet of the air conditioning module 4 are different.

[0062] When the air conditioning module 4 is in cooling operation, the first heat exchanger is an evaporator and the second heat exchanger is a condenser, and the indoor air can be cooled by the first heat exchanger. When the air conditioning module 4 is in heating operation, the first heat exchanger is a condenser and the second heat exchanger is an evaporator, and the indoor air can be heated by the first heat exchanger.

[0063] The air conditioning module 4 can be a heat pump module for cooling only, a heat pump module for heating only, or a heat pump module with a cooling and heating switching function. When the air conditioning module 4 is a heat pump module with a cooling and heating switching function, the refrigerant circulation circuit includes, in addition to the above-mentioned components, a four-way valve connecting the compressor exhaust port, the compressor return port, the first heat exchanger, and the second heat exchanger. When the four-way valve is operated in the first valve position, the air conditioning module 4 is in cooling operation; when the four-way valve is operated in the second valve position, the air conditioning module 4 is in heating operation.

[0064] Furthermore, the air conditioning module 4 further comprises a water tank, which is used to collect and store condensed water generated by the first heat exchanger and / or the second heat exchanger during the heat exchange process. An exhaust pipe is provided in the water tank. When the water level in the water tank is greater than the target water level, the outlet of the exhaust pipe is immersed in the condensed water stored in the water tank. The smoke exhaust duct in the oil fume module 3 is provided with a vent connected to the water tank exhaust duct. The vent is provided with a flow direction switching valve. The flow direction switching valve can be used to switch the oil fume entering the smoke exhaust duct to flow in a first flow direction or a second flow direction. The first flow direction is that the oil fume entering the smoke exhaust duct is discharged to the outside from the smoke outlet connected to the outside, and the second flow direction is that the oil fume entering the smoke exhaust duct is sent to the water tank through the exhaust pipe. After being processed by the condensed water in the water tank, the oil fume can be sent to the outside through the smoke outlet of the smoke exhaust duct, or sent to the outside through the exhaust port of the air conditioning module 4, or even flow back to the indoor environment, etc.

[0065] Furthermore, a filter is provided at the smoke outlet of the smoke exhaust duct or in the smoke exhaust duct in the oil fume module 3 to filter the oil fume discharged from the smoke outlet. In this embodiment, the filter is a coarse filter. In other embodiments, the filter can also be set to other types of filters according to actual needs, such as a medium-efficiency filter, a high-efficiency filter, etc.

[0066] Furthermore, the integrated stove further includes an oil fume sensor 5, which is specifically used to detect the oil fume concentration in the indoor environment of the integrated stove. In this embodiment, the oil fume sensor 5 can be specifically arranged at the indoor exhaust port of the exhaust module 3. In other embodiments, the oil fume sensor 5 can also be arranged at other positions according to actual needs, such as on the stove 2, outside the housing 1, etc.

[0067] Furthermore, the integrated stove also includes a temperature detection module 6, which includes a first temperature sensor, which is specifically used to detect the temperature of the first heat exchanger or the second heat exchanger. Specifically, the first temperature sensor can be arranged on the coil of the first heat exchanger (such as the middle of the coil, the coil inlet and / or the coil outlet) or the coil of the second heat exchanger (such as the middle of the coil, the coil inlet and / or the coil outlet). Further, the temperature detection module 6 can also include a second temperature sensor, which can be used to detect the temperature of the indoor smoke inhaled by the smoke exhaust module. Specifically, the second temperature sensor can be used in the smoke exhaust duct.

[0068] Furthermore, the integrated stove also includes a control device. Figure 2 The above-mentioned air conditioning module 4, smoke exhaust module 3, oil fume sensor 5, and temperature detection module 6 are all connected to the control device here. The control device can be used to control the operation of the air conditioning module 4 and the smoke exhaust module 3, and can also be used to obtain data detected by the oil fume sensor 5 and the temperature detection module 6.

[0069] The control device includes: a processor 1001 (such as a CPU), a memory 1002, etc. The memory 1002 can be a high-speed RAM memory, or a stable memory (non-volatile memory), such as a disk memory. The memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0070] Those skilled in the art will understand that Figure 2 The device structure shown in the figure does not constitute a limitation of the device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0071] like Figure 2 As shown, the memory 1002 as a computer-readable storage medium may include a control program for the integrated stove. Figure 2 In the device shown, the processor 1001 can be used to call the control program of the integrated stove stored in the memory 1002, and execute the relevant step operations of the control method of the integrated stove in the following embodiments.

[0072] An embodiment of the present invention further provides a control method for an integrated stove, which is applied to control the above-mentioned integrated stove.

[0073] Reference Figure 3 , an embodiment of the control method of the integrated stove of the present application is proposed. In this embodiment, the control method of the integrated stove includes:

[0074] Step S10, obtaining the operation mode of the integrated stove;

[0075] The integrated stove can be divided into several operation modes according to the different functions it needs to achieve, such as smoke exhaust mode, disinfection mode, dehumidification mode, oil fume purification mode, defrost mode, etc. Among them, in the defrost mode, the integrated stove operates for the purpose of melting the frost on the heat exchanger in the air conditioning module.

[0076] The operation mode can be determined by obtaining the mode control command input by the user, or by generating a mode start command based on the monitored environmental parameters, or by the current operation parameters of the integrated stove. The defrost mode can be turned on by the user inputting a command, or by automatically generating a defrost command to turn on the defrost mode when the coil temperature of the heat exchanger in the air conditioning module is detected to be less than or equal to the freezing point.

[0077] Specifically, step S10 is performed during the heating process of the air conditioning module. Specifically, whether there is a defrost instruction during the heating process of the air conditioning module is detected, and if a defrost instruction is detected, it can be determined that the operation mode of the integrated stove is the defrost mode.

[0078] Step S20, when the operation mode is the defrost mode, controlling the smoke exhaust module to blow the sucked indoor smoke toward the target heat exchanger in the air conditioning module to defrost the target heat exchanger.

[0079] The target heat exchanger is specifically a heat exchanger in the air conditioning module that needs to perform a defrosting operation. The target heat exchanger can be the first heat exchanger or the second heat exchanger. For example, when the indoor temperature is low, the air conditioner is in a cooling operation for a long time, which will cause frost on the first heat exchanger. In this case, the first heat exchanger can be used as the target heat exchanger. For another example, when the outdoor temperature is low, the air conditioner is in a heating operation and the second heat exchanger exchanges heat with the outdoor air for a long time, which will cause frost on the second heat exchanger. In this case, the second heat exchanger can be used as the target heat exchanger.

[0080] In the defrost mode of the integrated stove, the smoke exhaust module is turned on. When the smoke exhaust module is turned on, the smoke exhaust fan in the smoke exhaust duct drives the indoor smoke into the smoke exhaust duct, and the bypass valve between the smoke exhaust duct and the cavity where the target heat exchanger is located is opened. The smoke sucked in by the smoke exhaust fan can enter the cavity where the target heat exchanger is located through the channel opened by the bypass valve, and the smoke carrying heat is blown to the target heat exchanger to melt the frost on the target heat exchanger and even the frost in the cavity where the target heat exchanger is located. In this process, the smoke exhaust module can operate at a pre-set fixed wind speed, or it can operate at an operating wind speed determined based on the actual operating state of the integrated stove in the current defrost mode.

[0081] Among them, in the defrost mode, the air conditioning module can operate in cooling, heating, or shutdown, that is, the target heat exchanger can be a condenser, an evaporator, or even a non-heat exchange state. Among them, when the target heat exchanger is an evaporator or in a non-heat exchange state, the air inlet of the cavity where the target heat exchanger is located can be closed to avoid the low-temperature airflow entering from the air inlet and affecting the defrost efficiency. Furthermore, when the target heat exchanger is an evaporator or in a non-heat exchange state, the air temperature of the air inlet of the cavity where the target heat exchanger is located can be detected first. If the air temperature is lower than the set threshold (greater than or equal to the freezing point temperature), the air inlet of the cavity where the target heat exchanger is located is closed; if the air temperature is higher than the set threshold, the air inlet of the cavity where the target heat exchanger is located can be opened and closed so that the indoor air or outdoor air with a higher temperature entering through the air inlet can cooperate with the flue gas to improve the defrost efficiency of the target heat exchanger. In this embodiment, in the defrost mode, the target heat exchanger is a condenser to cooperate with the flue gas to improve the defrost efficiency. In order to ensure the normal operation of the refrigerant circulation system, the air inlet of the cavity where the target heat exchanger is located can be continuously or intermittently opened to ensure that the target heat exchanger serving as a condenser can normally exchange heat with the air coming in from the air inlet.

[0082] A control method for an integrated stove is proposed in an embodiment of the present invention. The method is based on an integrated stove including an air conditioning module and a smoke exhaust module, wherein the air conditioning module can be used to adjust the indoor ambient temperature to avoid the kitchen temperature being too high or too low, thereby ensuring the thermal comfort of users in the kitchen. On this basis, in the defrosting mode of the integrated stove, the indoor smoke sucked in by the smoke exhaust module is blown toward the target heat exchanger. Since the indoor smoke is generally generated during the cooking process, the smoke will carry a certain amount of heat. Therefore, the smoke sucked in by the smoke exhaust module is blown toward the target heat exchanger. The heat carried by the smoke can be used to melt the frost on the target heat exchanger, thereby achieving defrosting of the target heat exchanger, thereby avoiding the influence of the frosting of the heat exchanger on the heat exchange capacity output of the air conditioning module, thereby ensuring the heat exchange effect of the air conditioning module on the indoor environment.

[0083] Further, in this embodiment, in the defrost mode, it is possible to first detect whether the cooking module such as the cooker on the integrated stove is turned on. If it is turned on, indicating that smoke is generated, the exhaust module can be controlled to be turned on, and the smoke sucked by the exhaust module can be used to defrost the target heat exchanger; if the cooking module such as the cooker is not turned on, the temperature of the smoke sucked by the exhaust module can be detected. When the detected temperature is greater than or equal to the set threshold, the exhaust module can be controlled to defrost the target heat exchanger using the sucked smoke; when the detected temperature is less than the set threshold, the heating module in the exhaust module can be controlled to be turned on and then the exhaust module can defrost the target heat exchanger using the sucked smoke. Alternatively, if the target heat exchanger is the second heat exchanger, in the defrost mode, if it is determined that the air conditioning module is in the heating operation state before entering the defrost mode (that is, the first heat exchanger is a condenser), it is not necessary to detect whether the cooking module is turned on, and the exhaust module can be directly turned on, and the smoke sucked from the room by the exhaust module is blown to the target heat exchanger, thereby melting the frost on the target heat exchanger. Alternatively, in the defrost mode, if it is detected that the smoke exhaust module is in the on state, the smoke introduced from the room by the smoke exhaust module can be blown to the target heat exchanger, thereby achieving defrosting of the target heat exchanger.

[0084] Further, based on the above embodiment, another embodiment of the control method of the integrated stove of the present application is proposed. In this embodiment, the control of the smoke exhaust module to blow the inhaled indoor smoke to the target heat exchanger in the air conditioning module in step S20 is defined as step S20a, referring to Figure 4 , after step S10, further comprising:

[0085] Step S11, when the operation mode is the defrost mode, obtaining the first temperature of the target heat exchanger and the oil fume concentration of the space where the integrated stove is located;

[0086] In defrost mode, the first temperature and oil smoke concentration here can be detected in real time or at set intervals.

[0087] The first temperature can be specifically detected by a temperature sensor disposed on the target heat exchanger coil. The fume concentration can be specifically detected by an fume sensor disposed at the indoor fume outlet of the fume exhaust module.

[0088] Step S12: When the first temperature is less than or equal to the first set temperature, and the oil smoke concentration is less than or equal to the first set concentration, execute step S20a.

[0089] The first set temperature is specifically a temperature threshold value for identifying whether the target heat exchanger is frosted. The first set temperature is less than or equal to the freezing point. In this embodiment, the first set temperature is less than the freezing point.

[0090] The first set concentration is specifically a critical concentration for identifying whether the smoke sucked in by the smoke exhaust module will pollute the target heat exchanger.

[0091] When the first temperature is less than or equal to the first set temperature, and the oil fume concentration is less than or equal to the first set concentration, it indicates that the current target heat exchanger is in a frosted state, and the oil fume concentration is not easy to pollute the target heat exchanger. At this time, the smoke exhaust module uses the smoke sucked from the room to defrost the target heat exchanger, which can ensure the cleanliness of the target heat exchanger and the freshness of the indoor air while achieving defrosting of the target heat exchanger, ensuring the heat exchange effect of the air-conditioning module on the indoor environment, so as to effectively adjust the indoor environment temperature and meet the user's temperature comfort.

[0092] Further, based on the above embodiment, another embodiment of the control method of the integrated stove of the present application is proposed. Figure 5 , after step S11, further comprising:

[0093] Step S30, when the first temperature is greater than the second set temperature and the oil smoke concentration is greater than the second set concentration, controlling the exhaust module to exhaust the sucked indoor smoke to the outside, and controlling the air conditioning module to defrost the target heat exchanger through the heat dissipated by the target heat exchanger;

[0094] The second set temperature is greater than or equal to the first set temperature, and the second set concentration is greater than or equal to the first set concentration.

[0095] In this embodiment, the second set temperature is greater than the first set temperature. In other embodiments, the second set temperature may also be equal to the first set temperature. Specifically, in this embodiment, the second set temperature is the freezing point temperature (0°C). In other embodiments, the second set temperature may also be greater than the freezing point temperature.

[0096] Specifically, in this embodiment, the value range of the first set concentration is [1 mg / m 3 , 2mg / m 3 ], the value range of the second set concentration is 2mg / m 3 above.

[0097] In this embodiment, when entering the defrost mode or when the first temperature is greater than the second set temperature and the fume concentration is greater than the second set concentration, the air conditioning module can be controlled to operate in a target state, in which the target heat exchanger is a condenser and is in a heat release state. Based on this, when the smoke exhaust module discharges the sucked indoor smoke to the outside, the target heat exchanger can melt the frost through the heat generated by the refrigerant circulation of the air conditioning module.

[0098] In this embodiment, when the first temperature is greater than the second set temperature and the oil fume concentration is greater than the second set concentration, it indicates that the defrosting of the current target heat exchanger is nearly completed (there is less frost on the heat exchanger) and the oil fume blowing to the target heat exchanger will pollute the target heat exchanger. At this time, the target heat exchanger is no longer defrosted by flue gas, but the heat of the target heat exchanger itself is used to defrost, thereby defrosting and avoiding polluting the target heat exchanger.

[0099] In other embodiments, when the first temperature is greater than the second set temperature and the fume concentration is greater than the second set concentration, in addition to exhausting the fume outdoors, the air conditioning module can also be controlled to introduce air into the indoor target position to defrost the target heat exchanger through the introduced indoor air. Specifically, the indoor smoke exhaust port of the exhaust module is located above the cooking module such as the stove, and the target position here is located below the cooking module such as the stove (for example, the bottom of the integrated stove). Based on this, while the fume with a higher degree of pollution is discharged outdoors through the indoor smoke exhaust port above, the air with a higher degree of cleanliness at the bottom can be introduced into the cavity where the target heat exchanger is located to melt the frost on the target heat exchanger. In this process, the air conditioning module can operate in the above-mentioned target state or be shut down.

[0100] Further, based on any of the above embodiments, another embodiment of the control method of the integrated stove of the present application is proposed. Figure 6 , after step S10, further comprising:

[0101] Step S201, when the operation mode is the defrost mode, obtaining a first temperature of the target heat exchanger and a fume concentration of a space where the integrated stove is located;

[0102] The first temperature and oil fume concentration here refer to the same concepts as the first temperature and oil fume concentration mentioned above. The specific acquisition method can be found in the above embodiment and will not be described in detail here.

[0103] Step S202, determining a target operating wind speed of the smoke exhaust module according to the first temperature and the oil smoke concentration;

[0104] Different first temperatures and different fume concentrations correspond to different target operating wind speeds. Different target operating wind speeds correspond to different exhaust fan speeds, so the exhaust speed of the smoke exhaust module (ie, the speed of sucking fume from the indoor environment per unit time) is different.

[0105] In this embodiment, as the first temperature increases and the oil fume concentration increases, the target operating wind speed may decrease to achieve defrosting while reducing pollution to the target heat exchanger. In other embodiments, as the first temperature increases and the oil fume concentration increases, the target operating wind speed may also increase.

[0106] The correspondence between the first temperature, the oil fume concentration and the target operating wind speed can be established in advance, which can be in the form of a calculation relationship, a mapping relationship, etc. Based on the preset correspondence between the heat exchanger temperature, the oil fume concentration and the operating wind speed of the exhaust module, the operating wind speed corresponding to the current target heat exchanger temperature and oil fume concentration can be determined by calculation or querying a mapping table.

[0107] In this embodiment, the oil smoke concentration is pre-divided into at least two different concentration intervals, and the temperature of the target heat exchanger is pre-divided into at least two different temperature intervals. Different concentration intervals and different temperature intervals correspond to different operating wind speeds of the smoke exhaust module. As the temperature of the target temperature interval increases and the concentration of the target concentration interval increases, the target operating wind speed tends to decrease. The concentration intervals and / or temperature intervals divided here can be continuous intervals or discontinuous intervals. The concentrations in all the divided concentration intervals are less than the first set concentration mentioned above, and the concentrations in all the divided temperature intervals are less than the first set temperature mentioned above.

[0108] Based on the above-mentioned interval division, step S202 includes: determining a target temperature interval in which the first temperature is located, determining a target concentration interval in which the oil fume concentration is located; and determining the target operating wind speed according to the target temperature interval and the target concentration interval.

[0109] The at least two preset concentration intervals include a first concentration interval, a second concentration interval, and a third concentration interval, and the at least two preset temperature intervals include a first temperature interval, a second temperature interval, and a third temperature interval. When the target temperature interval is the first temperature interval and the target concentration interval is the first concentration interval, the first wind gear is determined to be the target operating wind gear; when the target temperature interval is the second temperature interval and the target concentration interval is the second concentration interval, the second wind gear is determined to be the target operating wind gear; when the target temperature interval is the third temperature interval and the target concentration interval is the third concentration interval, the third wind gear is determined to be the target operating wind gear; wherein the temperature in the first temperature interval is less than the temperature in the second temperature interval, the temperature in the second temperature interval is less than the temperature in the third temperature interval, the concentration in the first concentration interval is less than the concentration in the second concentration interval, the concentration in the second concentration interval is less than the concentration in the third concentration interval, the first wind gear is greater than the second wind gear, and the third wind gear is greater than the first wind gear. Specifically, the above-mentioned first set temperature is the maximum critical value of the second temperature interval, and the above-mentioned second set temperature is the minimum critical value of the third temperature interval. The first set concentration is the maximum critical value of the second concentration interval, and the second set concentration is the minimum critical value of the third concentration interval.

[0110] Step S203, controlling the smoke exhaust module to operate at the target operating wind speed; and executing step S20a during the execution of step S203.

[0111] In this embodiment, the operating wind speed of the smoke exhaust module is determined according to the oil fume concentration and the temperature of the target heat exchanger during the defrosting process, which is beneficial to ensure the freshness of the indoor air while achieving an effective balance between energy-saving defrosting using waste heat and avoiding pollution of the target heat exchanger by smoke with excessively high concentrations.

[0112] Step S201 here and the above-mentioned step S11 may specifically be the same step. Based on this, after step S201, step S202 is executed. When the first temperature is less than or equal to the first set temperature, and the oil fume concentration is less than or equal to the first set concentration, step S203 is executed and step S20a is executed; when the first temperature is greater than the second set temperature, and the oil fume concentration is greater than the second set concentration, step S203 is executed and the smoke exhaust module is controlled to discharge the sucked indoor smoke to the outside, and the air-conditioning module is controlled to defrost the target heat exchanger through the heat dissipated by the target heat exchanger, or other methods mentioned in the above embodiments.

[0113] Further, based on any of the above embodiments, another embodiment of the control method of the integrated stove of the present application is proposed. In this embodiment, after step S20 or the above step S30, it also includes: obtaining the current second temperature of the target heat exchanger; when the second temperature is less than the target temperature, returning to the step of controlling the smoke exhaust module to blow the sucked indoor smoke to the target heat exchanger in the air conditioning module; when the second temperature is greater than or equal to the target temperature, controlling the integrated stove to exit the defrosting mode.

[0114] The target temperature is specifically a critical temperature that indicates whether the defrosting of the target heat exchanger is completed. In this embodiment, the target temperature is greater than the second set temperature.

[0115] When step S11 is included after step S10, when the second temperature is lower than the target temperature, the process may return to step S11.

[0116] Here, by comparing the target heat exchanger temperature with the target temperature, automatic identification of whether the target heat exchanger has completed defrosting can be achieved, thereby ensuring that the integrated stove exits the defrost mode in time and quickly restores the normal operation of the air-conditioning module (such as restoring to heating operation).

[0117] Furthermore, when the second temperature is greater than or equal to the target temperature, the target heat exchanger of the air conditioning module can be controlled to operate in a target operating state for a set period of time, where the target operating state is that the target heat exchanger is a condenser and the heat exchanger temperature is greater than or equal to a set temperature threshold. When the target heat exchanger operates in the target operating state for a set period of time, the integrated stove is controlled to exit the defrost mode. Here, after defrosting is completed, the target heat exchanger is controlled to release heat at a sufficiently high temperature for a period of time, so as to use the dissipated heat to melt the oil stains attached to the surface of the heat exchanger during the defrosting process of oil smoke, so as to clean the target heat exchanger and further avoid smoke pollution of the target heat exchanger.

[0118] Further, based on any of the above embodiments, the air conditioning module includes a first heat exchanger and a second heat exchanger connected by a refrigerant pipeline, the first heat exchanger is used to exchange heat with indoor air, and the target heat exchanger is the second heat exchanger. After the step of obtaining the operation mode of the integrated stove, it also includes: when the operation mode is the defrost mode, controlling the air conditioning module to operate in a refrigeration mode to defrost the target heat exchanger; during the refrigeration operation of the air conditioning mode, executing the step of controlling the smoke exhaust module to blow the inhaled indoor smoke to the target heat exchanger in the air conditioning module; wherein, when the air conditioning module operates in a refrigeration mode, the first heat exchanger is an evaporator, and the second heat exchanger is a condenser. Here, the target heat exchanger is released by refrigeration of the air conditioning module, and the waste heat of the smoke is used to cooperate with defrosting, which is conducive to improving the defrosting efficiency.

[0119] Furthermore, in this embodiment, the air-conditioning module also includes a compressor, and the first heat exchanger and the second heat exchanger are both connected to the compressor through a refrigerant pipeline. The step of controlling the cooling operation of the air-conditioning module includes: obtaining the flue gas temperature of the indoor flue gas inhaled by the smoke exhaust module; determining the frequency limit value of the compressor operation according to the flue gas temperature; and controlling the compressor to operate at a frequency less than or equal to the frequency limit value.

[0120] The flue gas temperature here can be specifically detected by a temperature sensor in the exhaust duct or at the exhaust duct outlet. The frequency limit value is specifically the maximum frequency value allowed for the compressor to operate. Different flue gas temperatures correspond to different frequency limit values. The higher the flue gas temperature, the smaller the frequency limit value.

[0121] In this embodiment, the maximum frequency allowed for the operation of the compressor in the air-conditioning module is limited based on the flue gas temperature, which is beneficial to ensure that the flue gas and the air-conditioning module cooperate to reach the temperature required for defrosting, so as to ensure the defrosting effect while reducing the output of the air-conditioning module during the defrosting process as much as possible to reduce the energy consumption of the air-conditioning module. At the same time, it can also avoid the target heat exchanger temperature being too high, so that when the air-conditioning module switches to heating operation after defrosting is completed, the system can quickly reach a stable operating state and improve the heating output efficiency.

[0122] In addition, an embodiment of the present invention further proposes a computer-readable storage medium, on which a control program for an integrated stove is stored. When the control program for the integrated stove is executed by a processor, relevant steps of any embodiment of the control method for the integrated stove as described above are implemented.
