Description

TECHNICAL FIELD

[0001] The present application relates to the field of household appliances, in particular to a kitchen equipment control method, device, readable storage medium and kitchen equipment. BACKGROUND

[0002] At present, for the range hood type kitchen equipment, the kitchen equipment can work in two modes of external circulation mode and internal circulation mode, that is, the working mode of the range hood type kitchen equipment can be set to the internal circulation mode or the external circulation mode according to different use scenarios. At present, the two modes are obviously distinguished on the control panel as the internal circulation mode and the external circulation mode. That is, the internal circulation mode and the external circulation mode are respectively provided with switches. However, this method may sometimes cause the user to press the wrong switch button, so that the equipment works in the wrong mode, which affects the emission of oil fume and reduces the user experience.

[0003] Therefore, how to propose a kitchen equipment which does not need to distinguish the internal circulation mode and the external circulation mode at the user level has become a technical problem to be solved at present. SUMMARY

[0004] The present application aims to at least solve one of the problems in the prior art or related art.

[0005] Therefore, one purpose of the present application is to provide a kitchen equipment control method.

[0006] Another purpose of the present application is to provide a kitchen equipment control device.

[0007] A third purpose of the present application is to provide a readable storage medium.

[0008] A fourth purpose of the present application is to provide a kitchen equipment.

[0009] To achieve the above purpose, the technical solution of the first aspect of the present application provides a kitchen equipment control method for a kitchen equipment, the kitchen equipment comprising an air exhaust device, the working mode of the kitchen equipment comprising an internal circulation mode and an external circulation mode, in the internal circulation mode, the air exhaust device circulates air in the space where the kitchen equipment is located, in the external circulation mode, the air exhaust device exhausts air to the outside of the space where the kitchen equipment is located, the control method comprising: determining the set mode of the kitchen equipment; when the set mode is the external circulation mode, controlling the kitchen equipment to work in the external circulation mode, and when the set mode is the internal circulation mode, controlling the kitchen equipment to work in the internal circulation mode.

[0010] The kitchen equipment control method provided by the technical solution of the application is used for kitchen equipment such as an extractor hood. Further, the kitchen equipment is a smoke stove integrated machine and / or an integrated stove. The kitchen equipment includes an air exhaust device, and the working mode of the kitchen equipment includes an internal circulation mode and an external circulation mode. In the internal circulation mode, the air exhaust device circulates air in the space where the kitchen equipment is located, and in the external circulation mode, the air exhaust device exhausts air to the outside of the space where the kitchen equipment is located. The steps of the control method are as follows: first, the set mode of the kitchen equipment is detected, and then the actual mode of the kitchen equipment is determined based on the set mode. For example, the set mode can be determined according to the state of the mode switch. Of course, when the kitchen equipment is installed, the equipment can also be debugged first, and then the operating parameters are obtained in the debugging stage. Then, it is determined whether the internal circulation mode or the external circulation mode is actual, and then it is determined whether the internal circulation mode or the external circulation mode is actual. By using the kitchen equipment control method of the application, it is not necessary to distinguish between the internal circulation mode and the external circulation mode on the control panel, thereby reducing the cost. Moreover, since the user does not need to distinguish between the internal circulation mode and the external circulation mode, the problem that the existing distinction between the internal circulation mode and the external circulation mode easily causes the user to press incorrectly and leads to poor oil fume exhaust effect is solved, and the user experience is improved.

[0011] Among them, the working mode of the extractor hood is determined according to the use scene, and after the scene is determined, the installation mode of the extractor hood also has differences in different working modes. Therefore, after the extractor hood is installed, its set mode cannot be changed at will, and it needs to work in the specified set mode. Of course, in the same scene mode, if the extractor hood can perform the internal circulation mode and the external circulation mode, the method of the application can also be used to determine the set mode.

[0012] In the above technical solution, the kitchen equipment further includes a mode switch, and the step of determining the set mode of the kitchen equipment specifically includes: obtaining the state of the mode switch, and determining the set mode based on the state of the mode switch. That is, it is determined whether the internal circulation mode or the external circulation mode is based on the state of the mode switch.

[0013] In the technical solution, the kitchen equipment comprises a mode switch, and the mode switch is only one, which is generally arranged on the back of the range hood and the like for hidden arrangement. The set mode determined by the mode switch comprises an inner circulation mode and an outer circulation mode. Specifically, when the kitchen equipment such as the range hood is initially installed in a house, the mode switch of the kitchen equipment is set to a corresponding mode position according to the actual installation condition, and the mode of the kitchen equipment is set, such as the inner circulation mode or the outer circulation mode. After the product is powered on, the mode switch on the kitchen equipment is detected, and then the state of the mode switch is determined, and then the mode of the equipment is determined based on the state of the mode switch and the set mode association table. That is, the mode switch herein can specifically refer to the inner circulation mode and the outer circulation mode. That is, the mode switch herein is a mode judgment switch, and is different from the inner circulation mode or the outer circulation mode selection switch in the prior art. Because, the switch can only provide a basis for mode judgment, but cannot determine the mode itself.

[0014] On the other hand, a default mode can also be set in advance, and then it is judged whether the mode switch is in the default mode, if yes, the mode set by the switch is entered, otherwise another working mode is entered. For example, if the default mode is the inner circulation mode, and the set mode of the switch is the inner circulation mode, the inner circulation mode is directly worked, otherwise, if the default mode is the outer circulation mode, and the set mode of the switch is the inner circulation mode, the non-default mode, that is, the inner circulation mode is worked. Conversely, the default mode can also be set as the outer circulation mode. By using the kitchen equipment control method of the present application, it is not necessary to distinguish the inner circulation mode and the outer circulation mode on the control panel, thereby reducing the cost, and because the user does not need to distinguish the inner circulation mode and the outer circulation mode, the problem that the user is prone to pressing incorrectly to cause poor oil exhaust effect caused by distinguishing the inner circulation mode and the outer circulation mode in the prior art is solved, and the user experience is improved. The so-called default mode is that the kitchen equipment works in the default mode under normal circumstances. If there is an accident, the non-default mode is worked.

[0015] The mode switch can be a physical switch, such as a mechanical switch arranged on the kitchen equipment, or a touch button. At the same time, the mode switch can also be a switch or a key arranged on a remote controller, a mobile phone and the like. That is, in the present application, the mode switch generally refers to all objects that can issue a mode determination instruction, and is not limited to a physical switch. For example, in a specific scheme, a mode setting instruction can be sent to the kitchen equipment through a mobile phone and the like, so that the kitchen equipment knows the "mode setting requirement". At this time, the mobile phone can also be understood as a mode switch.

[0016] Further, after determining that the installation state of the kitchen equipment is the inner circulation mode or the outer circulation mode, the determined mode can be directly updated as the preset mode, i.e. the default mode. In this way, the state data of the collection mode switch does not need to be collected in the subsequent start.

[0017] In the above technical solution, the step of determining the set mode of the kitchen equipment specifically includes: controlling the kitchen equipment to operate in the preset mode, acquiring the parameter when the kitchen equipment operates in the preset mode (i.e. the operating parameter in the preset mode); determining the set mode according to the comparison result of the parameter when the kitchen equipment operates in the preset mode and the inner circulation mode parameter or the outer circulation mode parameter, and storing the set mode. The inner circulation mode parameter is the standard operating parameter when the kitchen equipment operates in the inner circulation mode, and the outer circulation mode parameter is the standard operating parameter when the kitchen equipment operates in the outer circulation mode. Further, the process of determining the set mode according to the comparison result of the parameter when the kitchen equipment operates in the preset mode and the inner circulation mode parameter or the outer circulation mode parameter is that when the parameter when the kitchen equipment operates in the preset mode matches the inner circulation mode parameter, the set mode is determined as the inner circulation mode, and when the parameter when the kitchen equipment operates in the preset mode matches the outer circulation mode parameter, the set mode is determined as the outer circulation mode.

[0018] In this technical solution, when installing and debugging the range hood and the like, a test is generally performed first, which can also be understood as the first start. During the debugging stage of the first start, the filter screen and the like are definitely installed. The operating parameters in the inner circulation mode and the outer circulation mode have a large difference, and therefore, during the debugging stage or the first start, the preset mode (default mode) can be used for working, and then the state parameters during the operation in this stage, such as the power and the fan speed, are acquired. Then, the acquired power and fan speed and the like are compared with the standard operating parameters in the inner circulation mode and the outer circulation mode, i.e. it is determined whether the operating state parameters in the preset mode are closer to the inner circulation mode or the outer circulation mode. Then, the installation state of the kitchen equipment is determined to be the inner circulation mode or the outer circulation mode according to the determination result. This setting realizes the judgment and setting of the inner circulation mode and the outer circulation mode based on software, and therefore, no additional mode switch is needed, i.e. no switch needs to be set.

[0019] Further, after determining that the installation state of the kitchen equipment is the inner circulation mode or the outer circulation mode, the determined mode can be directly updated as the preset mode, i.e. the default mode. In this way, the state data of the collection mode switch does not need to be collected in the subsequent start.

[0020] Further, the kitchen equipment control method further comprises: setting the rotating speed of the air exhaust device to the first rotating speed in the case of the set mode being the inner circulation mode; and setting the rotating speed of the air exhaust device to the second rotating speed in the case of the set mode being the outer circulation mode. Further, the control method further comprises: in the case of the air exhaust device rotating at the first rotating speed, collecting the driving current and voltage of the air exhaust device, determining the first actual power of the air exhaust device according to the driving current and voltage; and in the case of the actual power being greater than the first preset power, controlling the kitchen equipment to stop and displaying a fault prompt. Further, the control method further comprises: in the case of the first actual power being less than or equal to the first preset power, controlling the kitchen equipment to enter the inner circulation mode.

[0021] In the technical scheme, after the kitchen equipment such as an oil press determines the working mode, the working state is first set, that is, the air exhaust device is controlled to operate at the first rotating speed, then the driving current and voltage of the air exhaust device are detected when the kitchen equipment operates at the first rotating speed, then the first actual power of the air exhaust device is calculated based on the driving current and voltage, and then it is determined based on the size of the first actual power of the air exhaust device and the first preset power whether the kitchen equipment has a filter screen missing fault and / or a pipeline air leakage fault. Specifically, in the case of the actual power being greater than the first preset power, the kitchen equipment is controlled to stop and a fault prompt is displayed. Otherwise, the determined inner circulation mode is used for normal work.

[0022] In the above technical scheme, in the case of the air exhaust device rotating at the first rotating speed, the power of the air exhaust device is the first power Pt 内 , in the case of the air exhaust device rotating at the first rotating speed without installing the filter screen of the kitchen equipment, the power of the air exhaust device is P 内 ', and the first preset power is P1 内 , wherein 1.2Pt 内 ≤P1 内 ≤P 内 '.

[0023] Further, in the case of the air exhaust device rotating at the first rotating speed, the control method further comprises: collecting the driving current and voltage of the air exhaust device, determining the first actual power of the air exhaust device according to the driving current and voltage; and / or obtaining and determining whether the air volume of the air exhaust device is greater than the first air volume; and in the case of the actual power being greater than the first preset power and / or the air volume of the air exhaust device being greater than the first air volume, controlling the kitchen equipment to stop and displaying a fault prompt.

[0024] In the technical solution, in the case that the set mode is the external circulation mode, the rotating speed of the air exhaust device is set to the second rotating speed, the driving current and voltage of the air exhaust device running at the second rotating speed are collected, and the second actual power of the air exhaust device is determined according to the driving current and voltage; further, in the case that the second actual power is less than or equal to the second preset power, the kitchen equipment is controlled to enter the external circulation mode.

[0025] In the technical solution, in the case that the set mode is the external circulation mode, the rotating speed of the air exhaust device is set to the second rotating speed. Then, the second actual power of the air exhaust device at the rotating speed is used to judge the fault. Only when there is no fault, the kitchen equipment is started. If there is a fault such as missing filter screen, the kitchen equipment is not started. In this way, the user can be informed in time when the kitchen equipment has a fault, so as to facilitate the maintenance of the kitchen equipment.

[0026] Further, the second preset power is P1 外 In the case that the air exhaust device rotates at the second rotating speed, the power of the air exhaust device is the second power Pt 外 In the case that the air exhaust device rotates at the second rotating speed, the power of the air exhaust device is the second power Pt 外 ’. 外 ≤P1 外 ≤P 外 ’.

[0027] In any of the above technical solutions, the kitchen equipment control method further comprises: determining a third preset parameter threshold based on the set mode determined by the kitchen equipment; acquiring a third preset parameter when the kitchen equipment works in the set mode; and determining that the kitchen equipment needs cleaning and maintenance when the third preset parameter is less than the third preset parameter threshold, and giving a cleaning and maintenance prompt, wherein the cleaning and maintenance comprises at least one of kitchen equipment cleaning, filter screen replacement and grease separator replacement.

[0028] In the technical solution, the kitchen equipment control method further comprises determining a third preset parameter threshold according to the working mode of the kitchen equipment, obtaining a third preset parameter in different working modes, comparing the third preset parameter with the third preset parameter threshold, and determining that the kitchen equipment needs cleaning and maintenance when the third preset parameter threshold is greater than the third preset parameter, and giving a cleaning and maintenance prompt. The cleaning and maintenance comprises at least one of filter screen replacement, kitchen equipment cleaning and grease separator replacement. This solution can remind the user to clean the kitchen equipment in time, prevent the kitchen equipment from being blocked, make the oil fume be discharged in time and better, and improve the user experience.

[0029] Further, in the case that the set mode is the internal circulation mode, the motor power of the air exhaust device is less than a third preset power value P3 内When the motor power of the air exhaust device is less than the third preset power value P3 in the external circulation mode, it is determined that the kitchen device needs cleaning and maintenance. 外 When the motor power of the air exhaust device is less than the third preset power value P3 in the external circulation mode, it is determined that the kitchen device needs cleaning and maintenance.

[0030] In the technical scheme, the control method of the kitchen device further comprises: after the working mode of the kitchen device is determined, the kitchen device is controlled to work in the determined working mode.

[0031] Further, the fault prompt comprises one or more of a sound prompt, an optical prompt, a vibration prompt, and a display fault information prompt.

[0032] In the technical scheme, the step of obtaining the motor power of the air exhaust device comprises: obtaining a motor current and a motor voltage, and calculating the motor power based on the motor current and the motor voltage.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0057] In the following description, a lot of specific details are set forth in order to facilitate a thorough understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0058] The kitchen equipment control method provided by the embodiments according to the present application will be described below with reference to Figures 1 to 3 .

[0059] Embodiment One

[0060] The embodiments of the first aspect of the present application provide a kitchen equipment control method, for a kitchen equipment, the kitchen equipment comprising an air exhaust device, the working mode of the kitchen equipment comprising an inner circulation mode and an outer circulation mode, in the inner circulation mode, the air exhaust device circulates air in the space where the kitchen equipment is located, in the outer circulation mode, the air exhaust device exhausts air to the outside of the space where the kitchen equipment is located, such as Figure 1 as shown, the control method comprises:

[0061] S102, determining a set mode of the kitchen device;

[0062] S104, when the set mode is the external circulation mode, controlling the kitchen device to work in the external circulation mode, and when the set mode is the internal circulation mode, controlling the kitchen device to work in the internal circulation mode.

[0063] The kitchen device control method according to the embodiments of the present application is used for kitchen devices such as range hoods. Further, the kitchen device is a combination of a gas stove and a hood, and / or an integrated stove. The kitchen device comprises an air exhaust device, and the working mode of the kitchen device comprises an internal circulation mode and an external circulation mode. In the internal circulation mode, the air exhaust device circulates air in the space where the kitchen device is located, and in the external circulation mode, the air exhaust device exhausts air to the outside of the space where the kitchen device is located. The steps of the control method are as follows: first, detecting the set mode of the kitchen device, and then determining the actual mode of the kitchen device based on the set mode. For example, the set mode can be determined according to the state of a mode switch. Of course, when the kitchen device is installed, the device can be debugged first, and then during the debugging stage, the operating parameters are obtained, and then it is determined whether the actual mode is the internal circulation mode or the external circulation mode, and then it is determined whether the device is in the internal circulation mode or the external circulation mode. By using the kitchen device control method of the present application, it is not necessary to distinguish between the internal circulation mode and the external circulation mode on the control panel, thereby reducing the cost. Moreover, since the user does not need to distinguish between the internal circulation mode and the external circulation mode, the problem that the user is prone to pressing the wrong mode and thus the oil fume exhaust effect is poor is solved, and the user experience is improved.

[0064] In a specific embodiment, the kitchen device further comprises a mode switch, and the step of determining the set mode of the kitchen device specifically comprises: obtaining the state of the mode switch, and determining the set mode based on the state of the mode switch. That is, it is determined whether the mode is the internal circulation mode or the external circulation mode based on the state of the mode switch.

[0065] In this embodiment, the set mode comprises the internal circulation mode and the external circulation mode. Specifically, when the kitchen device such as a range hood is initially installed in a house, the mode switch of the kitchen device is set to the corresponding mode position according to the actual installation condition, and the mode of the kitchen device is set, such as the internal circulation mode or the external circulation mode. After the product is powered on, the mode switch of the kitchen device is detected, and then the state of the mode switch is determined. Then, the mode of the device is determined based on the state of the mode switch and the switch state and the set mode association table.

[0066] In another aspect, a default mode can also be set in advance, and then it is determined whether the mode switch is in the default mode, if yes, the mode program set by the switch is entered, otherwise another working mode is entered. For example, if the default mode is the inner loop mode and the switch sets the mode as the inner loop mode, the inner loop mode is directly worked in, otherwise, if the default mode is the outer loop mode and the switch sets the mode as the inner loop mode, the non-default mode, i.e., the inner loop mode, is worked in. Conversely, the default mode can also be set as the outer loop mode. By using the kitchen equipment control method of the present application, the inner loop mode and the outer loop mode do not need to be distinguished on the control panel, thereby reducing the cost, and since the user does not need to distinguish the inner loop mode and the outer loop mode at the user level, the problem that the user is prone to pressing incorrectly to cause poor oil fume exhaust effect due to the existing distinction between the inner loop mode and the outer loop mode is solved, and the user experience is improved. The so-called default mode is that the kitchen equipment works in the default mode uniformly without unexpected situations. If there is an unexpected situation, the non-default mode is worked in.

[0067] Further, after determining that the installation state of the kitchen equipment is the inner loop mode or the outer loop mode, the determined mode can be directly updated as the preset mode, i.e., the default mode. Thus, the state data of the mode switch does not need to be collected when starting subsequently.

[0068] In a specific embodiment, the step of determining the set mode of the kitchen equipment specifically comprises: controlling the kitchen equipment to operate in a preset mode, acquiring parameters when the kitchen equipment operates in the preset mode; determining the set mode according to a comparison result of the parameters when the kitchen equipment operates in the preset mode and inner loop mode parameters or outer loop mode parameters, and storing the set mode.

[0069] In this embodiment, when installing and debugging the oil fume exhauster and the like, a trial run is generally performed, which can also be understood as the first start. During the debugging stage of the first start, the filter screen and the like are definitely installed. The operating parameters in the inner loop mode and the outer loop mode have great differences, and thus the preset mode (default mode) can be worked in during the debugging stage or the first start, and then the state parameters during the operation in this stage, such as the power and the fan speed, are acquired. Then, the acquired power and fan speed parameters are compared with the standard operating parameters in the inner loop mode and the outer loop mode, i.e., it is determined whether the operating state parameters in the preset mode are closer to the inner loop mode or the outer loop mode. Then, the installation state of the kitchen equipment is determined to be the inner loop mode or the outer loop mode according to the determination result.

[0070] Further, after determining that the installation state of the kitchen equipment is the inner loop mode or the outer loop mode, the determined mode can be directly updated as the preset mode, i.e., the default mode.

[0071] Further, the kitchen equipment control method further comprises: setting the rotating speed of the air exhaust device to a first rotating speed in the case of setting the mode to the internal circulation mode; and setting the rotating speed of the air exhaust device to a second rotating speed in the case of setting the mode to the external circulation mode. Further, the control method further comprises: in the case of rotating the air exhaust device at the first rotating speed, collecting the driving current and voltage of the air exhaust device, determining the first actual power of the air exhaust device according to the driving current and voltage; and in the case of the actual power being greater than a first preset power, controlling the kitchen equipment to stop and displaying a fault prompt. Further, the control method further comprises: in the case of the first actual power being less than or equal to the first preset power, controlling the kitchen equipment to enter the internal circulation mode.

[0072] In this embodiment, after the kitchen equipment such as an oil press determines the working mode, the working state is first set, that is, the air exhaust device is controlled to operate at a first rotating speed, and then the driving current and voltage of the air exhaust device when the air exhaust device operates at the first rotating speed can be detected, and then the first actual power of the air exhaust device can be calculated based on the driving current and voltage, and then whether the kitchen equipment has a filter screen missing fault and / or a pipeline air leakage fault and the like can be determined based on the size of the first actual power of the air exhaust device and the first preset power. Specifically, in the case of the actual power being greater than the first preset power, the kitchen equipment is controlled to stop and a fault prompt is displayed. Otherwise, the determined internal circulation mode is used for normal work.

[0073] In the above embodiment, in the case of the air exhaust device rotating at the first rotating speed, the power of the air exhaust device is a first power Pt 内 , in the case of the air exhaust device rotating at the first rotating speed without installing the filter screen of the kitchen equipment, the power of the air exhaust device is P 内 ', and the first preset power is P1 内 , wherein 1.2Pt 内 ≤P1 内 ≤P 内 '.

[0074] Further, in the case of the air exhaust device rotating at the first rotating speed, the control method further comprises: collecting the driving current and voltage of the air exhaust device, determining the first actual power of the air exhaust device according to the driving current and voltage; and / or obtaining and determining whether the air volume of the air exhaust device is greater than a first air volume; and in the case of the actual power being greater than the first preset power and / or the air volume of the air exhaust device being greater than the first air volume, the kitchen equipment is controlled to stop and a fault prompt is displayed.

[0075] In the above embodiments, when the setting mode is external circulation mode, the speed of the exhaust device is set to the second speed, the drive current and voltage of the exhaust device when it runs at the second speed are collected, and the second actual power of the exhaust device is determined based on the drive current and voltage; furthermore, when the actual power is less than or equal to the second preset power, the kitchen equipment is controlled to enter the external circulation mode.

[0076] In this embodiment, when the setting mode is external circulation mode, the speed of the exhaust device is first set. Then, fault diagnosis is performed based on the second actual power of the exhaust device at this speed. The device only starts when there is no fault; it does not start if there is a fault such as a missing filter. This allows the user to be promptly notified when kitchen equipment malfunctions, facilitating equipment maintenance.

[0077] Furthermore, the second preset power is P1 外 When the exhaust device rotates at the second speed, the power of the exhaust device is the second power Pt. 外 When the kitchen equipment filter is not installed, and the exhaust device is rotating at the second speed, the power of the exhaust device is P. 外 ', of which 1.2Pt 外 ≤P1 外 ≤P 外 '.

In the internal circulation mode, the exhaust device circulates air within the space where the kitchen equipment is located; in the external circulation mode, the exhaust device exhausts air to the outside of the space where the kitchen equipment is located. The kitchen equipment also includes a mode switch, and the control method includes:

[0080] S202, Obtain the state of the mode switch, and determine the set mode based on the state of the mode switch.

[0081] S204, when the setting mode is external circulation mode, controls the kitchen equipment to work in external circulation mode; when the setting mode is internal circulation mode, controls the kitchen equipment to work in internal circulation mode.

[0082] In the above embodiment, the setting mode includes the inner circulation mode and the outer circulation mode. Specifically, when the kitchen device such as the range hood is initially installed in the house, the mode switch of the kitchen device is set to the corresponding mode position according to the actual installation condition, and the mode of the kitchen device is set, such as the inner circulation mode or the outer circulation mode. After the product is powered on, the mode switch on the kitchen device is detected, and then the state of the mode switch can be determined, and then the mode of the device is determined based on the state of the mode switch and the switch state and the setting mode association table. On the other hand, a default mode can also be set in advance, and then it is judged whether the mode switch is in the default mode. If yes, the mode set by the mode switch is entered, otherwise another working mode is entered. For example, if the default mode is the inner circulation mode and the switch setting mode is the inner circulation mode, the inner circulation mode is directly used for working. Conversely, if the default mode is the outer circulation mode and the switch setting mode is the inner circulation mode, the non-default mode, i.e. the inner circulation mode, is used for working. Conversely, the default mode can also be set to the outer circulation mode. By using the kitchen device control method of the present application, the inner circulation mode and the outer circulation mode do not need to be distinguished on the control panel, thereby reducing the cost. Moreover, since the user does not need to distinguish the inner circulation mode and the outer circulation mode, the problem that the user is prone to pressing incorrectly to cause poor oil exhaust effect is solved, and the user experience is improved. The so-called default mode is that the kitchen device works in the default mode under normal circumstances. If there is an accident, the non-default mode is used for working.

[0083] Further, after it is determined that the installation state of the kitchen device is the inner circulation mode or the outer circulation mode, the determined mode can be directly updated as the preset mode, i.e. the default mode. In this way, when starting subsequently, the state data of the mode switch does not need to be collected.

[0084] In the above embodiment, the control method of the kitchen device further includes, after it is determined that the working mode of the kitchen device, the setting state and the first preset parameter threshold value are determined according to the working mode of the kitchen device before the step of making the kitchen device work in the setting state. Specifically, when the kitchen device works in the normal inner circulation mode or the outer circulation mode, the working parameters when the kitchen device has a fault and the working parameters when the kitchen device works normally are compared, so as to determine the setting state and the first preset parameter threshold value.

[0085] In the above embodiment, the first preset parameter and the first preset parameter threshold value can be determined by comparing the motor power of the exhaust device with the first power value. When the first power value is less than the motor power of the exhaust device, it is determined that the kitchen equipment has a fault, and a fault prompt is issued, or the machine is stopped. Of course, a fault prompt can also be issued before the machine is stopped. Before the fault detection, the kitchen equipment works in the set state, which can ensure that the error caused by external factors during the fault detection is avoided, that is, the condition before the detection is uniform.

[0086] Further, whether the kitchen equipment has a fault can also be determined by comparing the air volume of the fan with the first air volume. When the first air volume is less than the air volume of the fan, the kitchen equipment has a fault, and the system issues a fault prompt and stops, of course, the machine can also be directly stopped, or the machine can not be stopped after the fault prompt is issued.

[0087] The fan is driven by a brushless direct current motor controlled by a speed sensorless controller. When the kitchen equipment is in a normal working state, the fan runs at a constant speed, and a plurality of layers of filter screens are arranged on the pipeline air path.

[0088] In the above embodiment, the power of the motor is Pt, the first power value is P1, and P' is the power of the motor when the kitchen equipment is not installed with a filter screen in the determined working mode. 1.2Pt≤P1≤P'.

[0089] When the normal internal circulation mode or the external circulation mode is entered, the internal circulation mode rated speed is n1, the rated power is Pt1, the power is P1' when the filter screen is missing, the external circulation mode rated speed is n2, the rated power is Pt2, and the power is P2' when the filter screen is missing. When the filter screen is missing, the smoke pipe resistance becomes smaller, the smoke pipe resistance curve moves downward, the intersection point of the smoke pipe curve and the fan P-Q curve moves to the right, the air volume Q becomes larger, the fan does more work, and the output power becomes larger. According to the actual power comparison with and without the filter screen, the power threshold value P1 can be set. When in the internal circulation mode, 1.2Pt1≤P1≤P1', and when in the external circulation mode, 1.2Pt2≤P1≤P2'. When the actual motor power P is greater than P1 during operation, the user is reminded to install the filter screen or check whether the pipeline is leaking, and further, a fault code can be displayed to avoid that the oil smoke is not effectively discharged, which affects the user experience.

[0090] In the above embodiment, the kitchen equipment control method further comprises: determining a threshold value of the third preset parameter according to the working mode of the kitchen equipment; obtaining the third preset parameter when the kitchen equipment works according to the determined working mode; and determining that the kitchen equipment needs cleaning and maintenance when the threshold value of the third preset parameter is greater than the third preset parameter, and issuing a cleaning and maintenance prompt, wherein the cleaning and maintenance comprises at least one of filter screen replacement, kitchen equipment cleaning, and oil separator replacement.

[0091] In this embodiment, the kitchen equipment control method further comprises: determining a threshold value of the third preset parameter according to the working mode of the kitchen equipment; obtaining the third preset parameter when the kitchen equipment works according to the determined working mode; and determining that the kitchen equipment needs cleaning and maintenance when the threshold value of the third preset parameter is greater than the third preset parameter, and issuing a cleaning and maintenance prompt, wherein the cleaning and maintenance comprises at least one of filter screen replacement, kitchen equipment cleaning, and oil separator replacement.

[0092] The third preset parameter is related to the working mode, and the third preset parameter is different in different working modes, for example, in the inner circulation mode and the outer circulation mode. Of course, the threshold value of the third preset parameter is also different in different working modes, so that the working mode of the kitchen equipment can be accurately determined in different working modes, and the kitchen equipment can work normally.

[0093] In the above embodiment, when the second preset power value is greater than the motor power of the exhaust device, it is determined that the kitchen equipment needs cleaning and maintenance. If not, when the second preset power value is less than the motor power of the exhaust device, the kitchen equipment works normally.

[0094] In the above embodiment, the third preset power value is P2, the first power value is P1, and the power of the motor is Pt when working in the determined working mode. 0.70P1≤P2≤0.85P1.

[0095] After the product is used, oil fume accumulates on the oil separator and the filter screen, causing the smoke pipe resistance to become larger, the smoke pipe resistance curve to move upward, the intersection of the smoke pipe curve and the fan P-Q curve to move to the left, the air volume Q to become smaller, the power of the fan to become smaller, and the output power to become smaller. A power threshold P2 is set, and through experimental data, it is obtained that P2≈(0.70-0.85)P1 in the inner circulation mode and P2≈(0.70-0.85)P1 in the outer circulation mode. When P≤P1 occurs during operation, the user is reminded to clean or replace the oil separator or the filter screen, so as to avoid that the oil fume is not effectively discharged, affecting the user experience.

[0096] In any of the above embodiments, the control method of the kitchen device further comprises, after determining the working mode of the kitchen device, controlling the kitchen device to work in the determined working mode.

[0097] In the above embodiments, the fault prompt comprises one or more of an optical prompt, an acoustic prompt, a display fault information prompt, a vibration prompt, etc.

[0098] The step of obtaining the motor power of the air exhaust device comprises: obtaining the motor current and the motor voltage, and calculating the motor power based on the motor current and the motor voltage.

[0099] In the present application, the first preset parameter threshold, the third preset parameter threshold, the first power value, the third preset power value, etc. are related to the working mode, and in different working modes, for example, in the inner circulation mode and the outer circulation mode, the above parameters are different, of course, in different working modes, the above parameters can also be the same. For example, the first power value P1 is P1 内 in the inner circulation mode, and P1 外 in the outer circulation mode. The second preset power value P2 also includes P2 内 and P2 外 according to the inner circulation mode and the outer circulation mode. The corresponding parameters of the set state operation in different modes are also different according to the inner circulation mode and the outer circulation mode.

[0106] S310, controlling the kitchen device to operate in the stored set mode;

[0107] S312, obtaining a first preset parameter of the kitchen device operating in the set mode.

[0108] S314, determining whether the first preset parameter is greater than a first preset parameter threshold; if yes, turning to S316, if no, turning to S318;

[0113] S324, determining that the kitchen equipment needs cleaning and maintenance, and giving a cleaning and maintenance prompt;

[0114] S326, controlling the kitchen equipment to normally work in the set mode.

[0115] In this embodiment, when installing and debugging the range hood and the like, a test run is generally performed first, which can also be understood as the first start. In the debugging stage of the first start, the filter screen and the like are definitely installed. The running parameters in the inner circulation mode and the outer circulation mode have great differences, and therefore, in the debugging stage or the first start, the preset mode (default mode) can be used to work, and then the state parameters in the running at this stage, such as the power and the fan speed, are obtained. Then, the obtained power and fan speed and the like are compared with the standard running parameters in the inner circulation mode and the outer circulation mode, that is, it is determined whether the running state parameters in the preset mode are closer to the inner circulation mode or the outer circulation mode. Then, according to the determination result, it is determined whether the installation state of the kitchen equipment is the inner circulation mode or the outer circulation mode.

[0116] Embodiment Four

[0117] In this embodiment, the fan uses a speed sensorless FOC controller to drive a brushless DC motor, and the drive scheme uses speed and current double closed-loop control, and phase current sampling. When the product is in a rated working state, the fan runs at a constant speed, and a plurality of layers of filter screens are arranged on the pipeline air path. When the product is installed, the mode switch 5 on the main machine is turned to the corresponding mode position according to the actual installation condition, such as an internal exhaust mode or an external exhaust mode. After the product is powered on, the controller detects the mode switch 5 on the main machine to determine whether it is in the internal exhaust mode, and if so, enters the internal exhaust working mode program, otherwise enters the external exhaust working mode program. When running in the normal internal exhaust mode or the external exhaust mode, the rated speed of the internal exhaust mode is n1, the rated power is P1, and when the filter screen is missing, the power is P1'. The rated speed of the external exhaust mode is n2, the rated power is P2, and when the filter screen is missing, the power is P2'. When the filter screen is missing, the resistance of the smoke pipe becomes smaller, the smoke pipe resistance curve moves downward, the intersection of the smoke pipe curve and the fan P-Q curve moves to the right, the air volume Q becomes larger, the fan does more work, and the output power becomes larger (as shown in Figure 6 and Figure 7 In this application, according to the power comparison of the actual filter screen and the filter screen without filter screen, the power thresholds P1 T and P2 T are set respectively, 1.2P1≤P1 T ≤P1', 1.2P2≤P2 T ≤P2', when P>P1 T or P2 T occurs during operation, the user is reminded to install the filter screen or check whether the pipeline is leaking, and further, a fault code can be displayed to avoid the oil smoke from being effectively exhausted, which affects the user experience.

[0118] However, in the existing scheme, the following problems exist: The detection device, such as a trigger switch, needs to be added to timely remind the user when the filter screen is not installed or missing, but this requires additional cost; the control panel needs to be added to distinguish between the internal exhaust mode and the external exhaust mode, which requires additional cost and is easy to cause the user to press incorrectly, resulting in poor exhaust effect.

[0119] In this embodiment, the hardware current is detected, the actual running power P is calculated, the installation power threshold P T is set, the installation mode is judged by comparing the actual running power P and the threshold P T when used for the first time, and the corresponding program running mode is selected; further, the power thresholds P1 T and P2 T in the internal and external exhaust modes are set, the filter screen missing or pipeline air leakage and other problems are identified by comparing the power P and the threshold, and the user is reminded. The speed is automatically adjusted to make the fan achieve the best exhaust effect, such as constant air volume control.
