Description

Technical Field

[0001] This invention relates to the field of kitchen air conditioning technology, and more specifically, to a kitchen air conditioning device, its control method, and related apparatus. Background Technology

[0002] When cooking in the kitchen, users utilize various cooking utensils, which generate significant heat, raising the kitchen's internal temperature, especially during the summer months. This high temperature negatively impacts the cooking experience. To mitigate these issues, air conditioning units, such as under-cabinet units, are commonly installed in kitchens. However, because under-cabinet units have a low airflow height and the cool air descends, they can cause stratification of hot and cold air between the upper and lower layers of the kitchen. This hinders the removal of heat from the upper air, resulting in low cooling efficiency and an inability to meet users' cooling needs, leading to discomfort. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a kitchen air conditioning device and its control method and related apparatus, so as to at least solve the technical problem that the cooling effect of traditional cabinet-type refrigeration equipment has serious stratification of hot and cold air, resulting in low cooling efficiency and user discomfort.

[0004] To achieve the above objectives, the technical solutions adopted in the embodiments of the present invention are as follows:

[0005] A first aspect of the present invention provides a kitchen air conditioning device, comprising:

[0006] The body includes a first cavity, a second cavity, and a third cavity; the first cavity and the third cavity are respectively isolated from the second cavity; a return air vent is provided on one side of the first cavity; a condenser air inlet and a heat exhaust outlet are provided on both sides of the second cavity; and a lifting opening is provided on the top of the third cavity.

[0007] A refrigeration mechanism includes an evaporator, a condenser, and a compressor for forming a cooling circulation loop, as well as a heat exhaust fan; the evaporator is disposed in the first cavity, and its air inlet is connected to the return air inlet; the condenser is disposed in the second cavity, and its air inlet is connected to the condenser air inlet; the heat exhaust fan is disposed in the second cavity, and its air inlet is connected to the second cavity, and its air outlet is connected to the heat exhaust outlet;

[0008] The lifting and air supply mechanism includes a circulating fan disposed in the first cavity, an air supply assembly disposed in the third cavity, and a lifting and driving mechanism; the air inlet of the circulating fan is connected to the first cavity, and the air outlet is connected to the third cavity; the air supply assembly has an air supply port connected to the third cavity; the driving end of the lifting and driving mechanism is connected to the air supply assembly, and is used to drive the air supply assembly to extend out of the lifting and opening or retract into the third cavity;

[0009] The control mechanism is electrically connected to the refrigeration mechanism and the lifting drive mechanism, respectively, and is used to control the control state of the refrigeration mechanism according to the indoor temperature of the kitchen area where the unit is located, and to control the height of the air supply component extending from the lifting opening through the lifting drive mechanism.

[0010] A second aspect of the present invention provides a control method for a kitchen air conditioning unit, applied in the control mechanism of the kitchen air conditioning unit provided in the first aspect above, the method comprising:

[0011] The indoor temperature of the kitchen area where the kitchen air conditioning unit is located and the gas flow rate of the stove in the kitchen area are obtained;

[0012] When the indoor temperature is within a first temperature range and the gas flow rate is non-zero, the circulating fan is controlled to operate, and the lifting drive mechanism is controlled to drive the air supply assembly to move to a first height higher than the lifting opening.

[0013] When the indoor temperature is within the second temperature range and the gas flow rate is non-zero, the refrigeration mechanism is controlled to operate, and the lifting drive mechanism is controlled to drive the air supply component to move to the second height; wherein, any temperature value in the second temperature range is greater than any temperature value in the first temperature range, and the second height is higher than the first height.

[0014] A third aspect of the present invention provides a control device for a kitchen air conditioning unit, applied in the control mechanism of the kitchen air conditioning unit provided in the first aspect above, the device comprising:

[0015] The acquisition module is configured to acquire the indoor temperature of the kitchen area where the kitchen air conditioning unit is located and the gas flow rate of the stove in the kitchen area;

[0016] The control module is configured to: when the indoor temperature is within a first temperature range and the gas flow rate is non-zero, control the circulating fan to operate and control the lifting drive mechanism to move the air supply component to a first height higher than the lifting opening; when the indoor temperature is within a second temperature range and the gas flow rate is non-zero, control the cooling mechanism to operate and control the lifting drive mechanism to move the air supply component to a second height; wherein any temperature value in the second temperature range is greater than any temperature value in the first temperature range, and the second height is higher than the first height.

[0017] In a fourth aspect, the present invention provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the kitchen air conditioning equipment control method provided in the second aspect above.

[0018] The kitchen air conditioning equipment, its control method, and related devices provided in this invention, for the kitchen air conditioning equipment, by rationally arranging the installation positions of the evaporator, condenser, compressor, heat exhaust fan, and lifting air supply mechanism in the refrigeration mechanism, and further improving the air supply mechanism of the kitchen air conditioning equipment into a lifting air supply mechanism that can be raised and lowered, can enable the control mechanism to rationally control the refrigeration mechanism and the lifting air supply mechanism according to the indoor temperature of the kitchen area and the gas flow of the stove in the kitchen area. This allows the air processed by the refrigeration mechanism to be delivered to different heights through the air supply components, for example, delivered at a height higher than the human body, which can effectively reduce the phenomenon of cold air stratification between upper and lower layers, improve the cooling efficiency to a certain extent, better meet the user's cooling needs, and enhance the user's cooking experience.

[0019] The control method is applied to the control mechanism of kitchen air conditioning equipment. By combining indoor temperature and gas flow, the height of the air supply component is controlled. On the one hand, when the gas flow is non-zero and the indoor temperature is relatively low, only the circulating fan is turned on, and the air supply component is controlled to supply air at a lower height. This not only accelerates air circulation and prevents users from feeling hot, but also avoids the discomfort caused by directly turning on the cooling mechanism, which would result in a low temperature. It also saves energy consumption caused by directly turning on the cooling mechanism. On the other hand, when the gas flow is non-zero and the indoor temperature is relatively high, the cooling mechanism is turned on, and the air supply component is controlled to supply air at a higher height. This prevents the indoor temperature from rising while quickly removing heat from the upper air, reducing the stratification of hot and cold air between the upper and lower layers, and using cool air to bring a cooling sensation to the user. This is beneficial for improving cooling efficiency and enhancing the user's cooking experience.

[0045] To address the technical problem of severe stratification of hot and cold air in traditional under-cabinet refrigeration equipment, leading to low cooling efficiency and user discomfort, this invention provides a kitchen air conditioning unit. By rationally arranging the installation positions of the evaporator, condenser, compressor, exhaust fan, and lifting air supply mechanism within the refrigeration system, and further improving the air supply mechanism into a lifting air supply mechanism, the control system can rationally control the refrigeration and lifting air supply mechanisms based on the indoor temperature of the kitchen area and the gas flow rate of the stove. This allows the air processed by the refrigeration system to be delivered to different heights via the air supply components, for example, above human height. This effectively reduces the stratification of hot and cold air between layers, improving cooling efficiency to a certain extent, better meeting the user's cooling needs, and enhancing the user's cooking experience.

[0046] The following combination Figure 1 The kitchen air conditioning equipment provided in the embodiments of the present invention will be described below. Figure 1This is a schematic diagram of the internal structure of a kitchen air conditioning unit 100 according to an embodiment of the present invention. The kitchen air conditioning unit 100 includes:

[0047] The body 110 includes a first cavity, a second cavity, and a third cavity; the first cavity and the third cavity are respectively isolated from the second cavity; a return air inlet a is provided on one side of the first cavity; a condenser air inlet b and a heat exhaust outlet c are provided on both sides of the second cavity; and a lifting opening d is provided on the top of the third cavity.

[0048] The refrigeration mechanism includes an evaporator 121, a condenser 122, and a compressor 123 for forming a cooling circulation loop, as well as a heat exhaust fan 124; the evaporator 121 is disposed in the first cavity, and its air inlet is connected to the return air inlet a; the condenser 122 is disposed in the second cavity, and its air inlet is connected to the condenser air inlet b; the heat exhaust fan 124 is disposed in the second cavity, and its air inlet is connected to the second cavity, and its air outlet is connected to the heat exhaust outlet c;

[0049] The lifting and air supply mechanism includes a circulating fan 131 disposed in the first cavity, an air supply assembly 132 disposed in the third cavity, and a lifting drive mechanism 133; the air inlet of the circulating fan 131 is connected to the first cavity, and the air outlet is connected to the third cavity; the air supply assembly 132 has an air supply port connected to the third cavity; the drive end of the lifting drive mechanism 133 is connected to the air supply assembly 132, and is used to drive the air supply assembly 132 to extend out of the lifting opening d or retract into the third cavity;

[0050] The control mechanism is electrically connected to the refrigeration mechanism and the lifting drive mechanism 133, respectively. It is used to control the control state of the refrigeration mechanism according to the indoor temperature of the kitchen area where the unit 110 is located and the gas flow of the stove in the kitchen area, and to control the height of the air supply component 132 extending from the lifting opening d through the lifting drive mechanism 133.

[0051] The relevant principles by which the control mechanism controls the refrigeration mechanism and the lifting drive mechanism 133 based on the indoor temperature and gas flow can be found in the kitchen air conditioning equipment control method provided in the following embodiments of the present invention, and will not be elaborated here.

[0052] Furthermore, the aforementioned lifting drive mechanism 133 can be any type of linear drive mechanism, such as an electric cylinder, a linear motor, or a pneumatic cylinder mechanism.

[0053] Therefore, by installing the kitchen air conditioning unit of this embodiment in the kitchen, during the air supply operation of the kitchen air conditioning unit, the gas in the kitchen will flow into the first cavity and the second cavity due to the action of the evaporator 121 and the condenser 122. The gas entering the first cavity will be cooled by the action of the evaporator 121, and then sent to the air supply assembly 132 by the circulating fan 131, and then sent out to the kitchen through the air supply assembly 132 to achieve cooling of the kitchen; at the same time, the gas heated in the second cavity due to the heat exchange effect is drawn in by the heat exhaust fan 124 and discharged to the outside through the heat exhaust outlet c.

[0054] It should be noted that after the kitchen air conditioning equipment provided in this embodiment of the invention is installed in the kitchen, please refer to... Figure 2 , Figure 2 This is a schematic diagram of the usage state of a kitchen air conditioning unit 100 provided in an embodiment of the present invention. The top surface of its body 110 can be used as a kitchen countertop, which can expand the operable space of the kitchen countertop. Furthermore, regarding the aforementioned lifting air supply mechanism, when the kitchen air conditioning unit 100 is in the off or standby state, the air supply component 132 is housed in the third cavity, such as... Figure 3 As shown, Figure 3 This is a schematic diagram of the state in which the air supply component 132 of a kitchen air conditioning device is housed in the third cavity, according to an embodiment of the present invention. At this time, the air supply component 132 is in a hidden state, which can further expand the operable space of the kitchen countertop.

[0055] In order to reduce the manufacturing difficulty and cost of the lifting and air supply mechanism while ensuring its functionality, some embodiments of the present invention have simplified the structure of the air supply component 132 and the lifting drive mechanism 133. Please refer to... Figure 4 , Figure 4This is a schematic diagram of the internal structure of a lifting and air supply mechanism provided in an embodiment of the present invention. The air supply component 132 can be an air supply cavity with a rectangular cross-sectional shape. The top surface of the air supply cavity is flat and matches the shape of the lifting opening d, so as to smoothly realize the lifting and lowering movement at the lifting opening d. After being stored in the third cavity 113, the lifting opening d can be closed and flush with the lifting opening d, so as to avoid unevenness of the top surface of the body 110 and to prevent dust, kitchen utensils or food from falling into the third cavity 113 from the lifting opening d. In addition, an air supply port e is provided at the top of the side of the air supply cavity used for air supply to the user, and the bottom of the air supply cavity is open to communicate with the third cavity, so as to realize the entry of the gas processed by the refrigeration mechanism. The lifting drive mechanism 133 can be an electric push rod. The motor of the electric push rod can be installed on the inner bottom surface of the third cavity through a fixing member. The push rod of the electric push rod is set along the height direction of the third cavity, and the end of the push rod is connected to the inner top surface of the air supply cavity through a connector. Therefore, the extension and retraction of the push rod can drive the air supply cavity to move up and down along the third cavity.

[0056] In some embodiments, to adapt to various kitchens with different public flue layouts, the number of heat exhaust outlets c is increased. That is, another heat exhaust outlet c is provided on the side of the second cavity other than the two sides mentioned above. In this case, the second cavity has two heat exhaust outlets c, which can be located on opposite sides or adjacent sides. Based on this, the air outlet of the heat exhaust fan 124 is connected to the two heat exhaust outlets c respectively through a T-shaped tee pipe. As one example, please refer to... Figure 5 , Figure 5 This is a schematic diagram of the structural state after the exhaust fan 124 is connected to the T-shaped tee pipe 126 according to an embodiment of the present invention. Therefore, when installing the kitchen air conditioning equipment provided in this embodiment of the present invention, a suitable exhaust outlet c can be connected to the public flue A according to the location of the public flue in the kitchen, so that the heat generated subsequently can be discharged outdoors through the public flue, such as... Figure 2 As shown, this avoids the problems of increased operating costs and low heat dissipation efficiency caused by the need to lengthen the heat dissipation pipe due to the heat dissipation outlet c being on the same side as the common flue.

[0057] In some embodiments, to prevent condensate from accumulating in the first cavity, the present invention further includes a structure for introducing the condensate into the kitchen drain drain pipe, i.e., please refer to... Figure 1 The kitchen air conditioning equipment provided in this embodiment of the invention may further include a water receiving tray 125; the water receiving tray 125 is disposed in the first cavity and located below the evaporator 121, and is used to discharge condensate through a drain pipe 126 that passes through the first cavity.

[0058] In some embodiments, to reduce the entry of dust or other objects into the unit 110 from the return air inlet a or the condenser air inlet b, the present invention also adds a filter structure, that is, please refer to Figure 1 A filter screen a1 and a filter screen b1 are respectively installed at the return air inlet a and the condenser air inlet b.

[0059] In some embodiments, since the top surface of the body 110 can be used as a work surface, considering the potential need in practical applications to accelerate flour fermentation, dry the work surface, or dry the user's hands, this embodiment of the invention also adds a heating function in addition to the air supply and cooling functions. That is, please refer to... Figure 1 The kitchen air conditioning equipment provided in this embodiment of the invention may further include a heating mechanism 140, which is disposed in the first cavity. Correspondingly, a control mechanism may also be electrically connected to the heating mechanism 140 and is used to control the working state of the heating mechanism 140 according to the indoor temperature and gas flow rate. The control principle can be found in the relevant description below, and will not be elaborated here.

[0060] It should be noted that, to ensure the heating effect of the heating mechanism 140, the cooling mechanism will be in a switched-off or standby state when the heating mechanism 140 is activated. After the heating mechanism 140 is activated, the gas in the first chamber will heat up and then be sent to the kitchen space through the circulating fan 131 and the air supply assembly 132. This can raise the temperature of the kitchen space and also dry objects and hands placed by the user near the air outlet. In addition, since the top surface of the first chamber can be used as a kitchen countertop, the heating of the first chamber will also heat up its top surface. Therefore, the user can place flour that needs to be fermented on the top surface of the first chamber to accelerate the fermentation process.

[0061] In some embodiments, to improve the oxygen level in the kitchen space, thereby further improving air quality and enhancing the user experience, the present invention also adds a structure for introducing outdoor air into the room, i.e., please refer to... Figure 6 , Figure 6 This is a schematic diagram of the internal structure of another kitchen air conditioning unit provided in this embodiment of the invention. The kitchen air conditioning unit provided in this embodiment of the invention may further include a fresh air fan 150; correspondingly, a fresh air inlet is also provided on the other side of the first cavity. The air inlet of the fresh air fan 150 is connected to the fresh air inlet, and the air outlet is connected to the first cavity. Based on this, the control mechanism may also be electrically connected to the fresh air fan 150, and is also used to control the working state of the fresh air fan 150 according to the outdoor temperature, indoor temperature and the aforementioned gas flow rate of the kitchen area where the unit 110 is located. The control principle can be found in the relevant description below, and will not be elaborated here.

[0062] Therefore, by adding a fresh air fan 150, the fresh air flow and the supply air flow can be combined in the first cavity and then sent out to the kitchen space through the air supply component 132, thereby increasing the oxygen content in the kitchen space, which is beneficial to improving the air quality in the kitchen and enhancing the user experience.

[0063] In some embodiments, to improve the introduction or discharge efficiency of the relevant outlets in the above embodiments that require the introduction of gas from the outside or the discharge of gas or liquid to the outside, corresponding pipes can be connected to the outlets. For example, please refer to... Figure 7 , Figure 7 This is a schematic diagram of another kitchen air conditioning device provided in an embodiment of the present invention. As can be seen, a heat exhaust pipe can be installed at the heat exhaust outlet c; the drain pipe 126 for draining condensate can be extended to facilitate communication with a drain trough; and a fresh air intake pipe 151 can be installed at the fresh air inlet. In some other embodiments, a filter screen 152 can also be provided between the fresh air inlet and the fresh air intake pipe.

[0064] Furthermore, to achieve reasonable control of the refrigeration and lifting air supply mechanisms by the control mechanism, so that the kitchen air conditioning equipment can better improve the kitchen environment, this embodiment of the invention also provides a control method for kitchen air conditioning equipment. This control method can be applied to the control mechanism. Please refer to [reference needed]. Figure 8 , Figure 8 This is a structural block diagram of a control mechanism provided in an embodiment of the present invention. The control mechanism 800 includes a memory 810, a processor 820, and a communication module 830. The memory 810, processor 820, and communication module 830 are electrically connected to each other directly or indirectly to realize data transmission or interaction. For example, these components can be electrically connected to each other through one or more communication buses or signal lines.

[0065] The memory 810 is used to store programs or data. The memory 810 may be, but is not limited to, Random Access Memory (RAM), Read Only Memory (ROM), Programmable Read-Only Memory (PROM), Erasable Programmable Read-Only Memory (EPROM), Electrically Erasable Programmable Read-Only Memory (EEPROM), etc.

[0066] The processor 820 is used to read / write data or programs stored in the memory 810 and to perform corresponding functions.

[0067] The communication module 830 is used to establish a communication connection between the control mechanism and other communication terminals through the network, and to send and receive data through the network.

[0068] It should be understood that, Figure 8 The structure shown is only a schematic diagram of the control mechanism; the control mechanism may also include components such as... Figure 8 The more or fewer components shown, or having the same Figure 8 The different configurations shown. Figure 8 The components shown can be implemented using hardware, software, or a combination thereof.

[0069] The following combination Figure 9 The control method for kitchen air conditioning equipment provided in the embodiments of the present invention will be described. Figure 9 This is a flowchart of a kitchen air conditioning equipment control method provided by an embodiment of the present invention. The kitchen air conditioning equipment control method includes:

[0070] In step S100, the indoor temperature of the kitchen area where the kitchen air conditioning unit is located and the gas flow rate of the stove in the kitchen area are obtained;

[0071] In step S200, when the indoor temperature is within a first temperature range and the gas flow rate is non-zero, the circulating fan is controlled to operate, and the lifting drive mechanism is controlled to drive the air supply assembly to move to a first height higher than the lifting opening.

[0072] In step S300, when the indoor temperature is within the second temperature range and the gas flow rate is non-zero, the refrigeration mechanism is controlled to operate, and the lifting drive mechanism is controlled to drive the air supply component to move to the second height; wherein, any temperature value in the second temperature range is greater than any temperature value in the first temperature range, and the second height is higher than the first height.

[0073] Since users typically only feel hot when the indoor temperature is above 28℃, to meet user needs while reducing the computational complexity of the control mechanism, a basic solution is to divide the indoor temperature into two ranges: a first temperature range and a second temperature range. The first temperature range can be less than or equal to 28℃, while the second temperature range can be greater than 28℃. These two temperature ranges are then used to achieve basic control of the cooling and lifting / air supply mechanisms. Based on this, the principle of control based on steps S100 to S300 will be explained:

[0074] First, step S100 acquires the indoor temperature of the kitchen area where the kitchen air conditioning unit is located and the gas flow rate of the stove in the kitchen area. The indoor temperature can be obtained using a temperature sensor deployed in the kitchen area. In some examples, to know the temperature in advance and make timely control, the temperature sensor can be deployed in the area where the stove is located. The gas flow rate can be obtained using a flow sensor in the gas passage. To acquire the data collected by the temperature and flow sensors, the control mechanism is connected to both the temperature and flow sensors. The connection method can be wireless or wired communication; this embodiment of the invention does not limit this.

[0075] Once the indoor temperature and gas flow rate are known, it can be determined whether the indoor temperature falls within a first temperature range or a second temperature range. Similarly, it can be determined whether the gas flow rate is zero. When the gas flow rate is zero, it can be assumed that the user is not in the kitchen or that the kitchen will not be heated by the stove. Therefore, in some embodiments, when the gas flow rate is zero, the control mechanism can maintain its original control or put both the cooling mechanism and the lifting mechanism into standby mode.

[0076] When the gas flow rate is non-zero, if the indoor temperature is within the first temperature range, then step S200 is executed. The control mechanism controls the circulating fan to operate and controls the lifting drive mechanism to drive the air supply component to move to a first height H1 higher than the lifting opening. Figure 10 As shown, Figure 10 This is a schematic diagram of the air supply component in a kitchen air conditioning unit provided in an embodiment of the present invention when it is at the first height. It can be seen that at this time, there is no need to turn on the cooling mechanism; only the circulating fan needs to be turned on to send room-temperature air through the air supply component from the first height, which can accelerate the airflow in the kitchen and improve kitchen comfort. If the indoor temperature is within the second temperature range, then step S300 is executed, controlling the cooling mechanism to operate and controlling the lifting drive mechanism to drive the air supply component to move to the second height H1. Figure 11 As shown, Figure 11 This is a schematic diagram of the air supply component in a kitchen air conditioning unit provided by an embodiment of the present invention when it is at the second height. At this time, the refrigeration mechanism is activated so that the circulating fan sends the cooled gas through the air supply component from the second height, which is higher than the first height, thereby cooling the kitchen and improving kitchen comfort. The first height and the second height can be set according to experiments or experience.

[0077] In addition, the airflow direction B delivered by the air supply component can be referenced. Figure 12 , Figure 12 This is a schematic diagram of the airflow direction of a kitchen air conditioning device provided in an embodiment of the present invention.

[0078] Therefore, the kitchen air conditioning equipment control method provided in this embodiment of the invention controls the height of the air supply component by comprehensively considering indoor temperature and gas flow. On the one hand, when the gas flow is non-zero and the indoor temperature is relatively low, only the circulating fan is turned on, and the air supply component is controlled to supply air at a lower height. This not only accelerates air circulation and prevents users from feeling hot, but also avoids the discomfort caused by the low temperature due to directly turning on the cooling mechanism, and saves energy consumption caused by directly turning on the cooling mechanism. On the other hand, when the gas flow is non-zero and the indoor temperature is relatively high, the cooling mechanism is turned on, and the air supply component is controlled to supply air at a higher height. This can prevent the indoor temperature from rising while quickly removing heat from the upper air, reducing the stratification of hot and cold air between the upper and lower layers, and using cold air to bring a cool feeling to the user, which is beneficial to improving cooling efficiency and enhancing the user's cooking experience.

[0079] Furthermore, since the control strategy is determined solely by whether the gas flow rate is non-zero, and the magnitude of the gas flow rate can cause varying degrees of temperature increase in the kitchen space, thus affecting the user experience, in order to achieve more reasonable control and better improve the user experience, in some embodiments of the present invention, the relevant control of the above step S200 is further optimized. That is, the step of controlling the operation of the circulating fan in step S200 includes:

[0080] In step S210, when the gas flow rate is less than or equal to a set flow rate threshold, the circulating fan is controlled to operate at a low air supply speed.

[0081] In step S220, when the gas flow rate is greater than the flow rate threshold, the circulating fan is controlled to operate at a high-speed air supply.

[0082] For step S210, it is understandable that since the room temperature is relatively comfortable at this time and the stove is at a medium-low heat, only the low setting of the fan is turned on to provide airflow. Without cooling, the air circulation can be accelerated and the user will not feel hot.

[0083] For step S220, it is understandable that the stove is at high power and the heat load is relatively higher than in step S210. However, since the room temperature is relatively comfortable at this time, only the high-speed fan is turned on to supply air. Even without cooling, the air can be accelerated more quickly through the faster gas flow, so that the user will not feel hot.

[0084] The traffic thresholds mentioned in this article can be set based on experience or actual needs.

[0085] For the same reason, in some embodiments, the control related to step S300 can be further optimized based on any of the above embodiments. That is, the step of controlling the operation of the refrigeration mechanism in step S300 includes:

[0086] In step S310, when the gas flow rate is less than or equal to the flow rate threshold, the refrigeration mechanism is controlled to operate at a low refrigeration level.

[0087] In step S320, when the gas flow rate is greater than the flow rate threshold, the refrigeration mechanism is controlled to operate at the medium cooling speed.

[0088] For step S310, it is understandable that since the room temperature is high at this time, which is not a comfortable temperature for the human body, the cooling mechanism needs to be activated. However, the stove is at a medium-low power, so the low cooling setting is used to send cold air to the kitchen at a higher second height, which can achieve indoor cooling and improve the comfort of the kitchen environment.

[0089] For step S320, it is understandable that since the room temperature is high at this time, which is not a comfortable temperature for the human body, the cooling mechanism needs to be activated. However, the stove is at high power and the heat load is relatively high compared to step S220. Therefore, the cooling level needs to be increased, that is, the cooling level is set to medium and cold air is sent to the kitchen at a higher second height, which can achieve indoor cooling and improve the comfort of the kitchen environment.

[0090] When the indoor temperature is within the first temperature range and the gas flow rate is zero, the indoor temperature is still relatively comfortable. From the perspective of energy saving, in some embodiments, the control mechanism can control the entire kitchen air conditioning unit to be in standby mode. That is, the kitchen air conditioning unit control method provided in the embodiments of the present invention may further include:

[0091] In step S410, when the indoor temperature is within the first temperature range and the gas flow is zero, the refrigeration mechanism and the lifting and air supply mechanism are controlled to be in standby mode.

[0092] When the indoor temperature is within the second temperature range and the gas flow rate is zero, considering that the indoor temperature is relatively high and not comfortable for the human body, but because the gas flow rate is zero, the indoor temperature will not rise. Taking into account both human comfort and energy saving, in some embodiments, under this condition, the circulating fan can be controlled to operate at a low air supply speed, and the lifting drive mechanism can be controlled to drive the air supply component to move to the first height, without needing to turn on the refrigeration mechanism; that is, the kitchen air conditioning equipment control method provided in the embodiments of the present invention may further include:

[0093] In step S420, when the indoor temperature is within the second temperature range and the gas flow rate is zero, the circulating fan is controlled to operate at a low air supply speed, and the lifting drive mechanism is controlled to drive the air supply component to move to the first height.

[0094] In some embodiments, steps S210-S220, S310-S320, and S410-S420 can be combined to form a better control scheme, such as... Figure 13 As shown, Figure 13 This is a flowchart of another kitchen air conditioning equipment control method provided by an embodiment of the present invention. The relevant principles of each step in this control scheme can be found in the relevant records above, and will not be repeated here.

[0095] While dividing the temperature into a first temperature range of less than or equal to 28°C and a second temperature range of greater than 28°C in any of the above embodiments can achieve the purpose of improving the kitchen environment and enhancing user experience, users may already feel cold when the room temperature is less than or equal to 20°C, thus making it unnecessary to turn on the kitchen air conditioning equipment. Furthermore, generally speaking, the human body experiences significantly different sensations when the room temperature is in the three different temperature ranges of (20°C, 26°C), (26°C, 28°C), and (28°C, +∞). For example, (20°C, 26°C) is a relatively comfortable temperature, (26°C, 28°C) may feel somewhat stuffy, and (28°C, +∞) may feel hot. Therefore, if the temperature division method in any of the above embodiments is used for control, it may not be possible to make the air conditioning effect more closely match the actual environmental needs, thus resulting in room for improvement in user experience. Therefore, to solve this technical problem… In some embodiments, the first temperature range can be configured as (20°C, 26°C), the second temperature range as (26°C, 28°C), and a third temperature range (28°C, +∞) can be added. Based on this, when the indoor temperature is within the first or second temperature range, the kitchen air equipment control method in any of the above embodiments can continue to be used to achieve relevant control. Unlike any of the above embodiments, in this embodiment of the invention, a new control scheme is proposed for the third temperature range. Furthermore, since the configuration of the second temperature range differs greatly from that in any of the above embodiments, based on the relevant control scheme of the above embodiments, the effects of steps S310 to S320 and step S420 are explained again based on the second temperature range (26°C, 28°C):

[0096] For step S310, based on the second temperature range (26°C, 28°C) at this time, although the indoor temperature is between comfortable and hot, the stove is at medium and low power, which will increase the indoor heat load and easily cause the indoor temperature to rise gradually. Therefore, the low cooling setting is used to send cold air to the kitchen at a higher second height to prevent the indoor temperature from rising while using the cold air to bring a cool feeling to the user.

[0097] For step S320, based on the second temperature range at this time (26°C, 28°C), although the indoor temperature is between comfortable and hot, the stove is at high power and will generate more heat load. Therefore, the medium cooling setting is used to send cold air to the kitchen at a higher second height to offset the heat load brought by the high power, so as to avoid the user feeling hot while cooking.

[0098] For step S420, based on the second temperature range (26°C, 28°C) at this time, since the indoor temperature is between comfortable and hot, and since the stove is not turned on, the heat load will not increase. At this time, as long as the air supply is at a low setting and the air is supplied to the kitchen at a lower first height to accelerate the air flow, the user's comfort can be improved.

[0099] For the control scheme proposed above for the third temperature range, please refer to... Figure 14 , Figure 14 This is a flowchart of another kitchen air conditioning equipment control method provided in an embodiment of the present invention. The kitchen air conditioning equipment control method may further include:

[0100] In step S510, when the indoor temperature is within the third temperature range and the gas flow rate is zero, the refrigeration mechanism is controlled to operate at the medium cooling setting, and the lifting drive mechanism is controlled to drive the air supply assembly to move to the second height; and / or

[0101] In step S520, when the indoor temperature is within a third temperature range and the gas flow rate is less than or equal to a non-zero set flow rate threshold, the refrigeration mechanism is controlled to operate at a high cooling setting, and the lifting drive mechanism is controlled to drive the air supply assembly to move to the second height; and / or

[0102] In step S530, when the indoor temperature is within the third temperature range and the gas flow rate is greater than a non-zero set flow rate threshold, the refrigeration mechanism is controlled to operate at the high cooling level, and the lifting drive mechanism is controlled to drive the air supply component to move to the first height.

[0103] Wherein, any temperature value in the third temperature range is greater than any temperature value in the second temperature range.

[0104] In step S510, the indoor temperature is in the third temperature range, indicating that the room temperature has exceeded the human comfort temperature, so the cooling function is turned on. Since the stove is off at this time, the medium cooling setting is used to send cold air to the kitchen at a higher second height to prioritize cooling the room and improve the user experience.

[0105] In step S520, the indoor temperature is in the third temperature range, indicating that the room temperature has exceeded the human comfort temperature, so the cooling function is turned on. Since the stove is at medium to low power at this time, the high room temperature combined with the stove's heat load will cause the room temperature to rise significantly. To avoid this phenomenon, the high cooling setting is used to send cold air to the kitchen at a higher second height, prioritizing the cooling of the room and improving the user experience.

[0106] In step S530, the indoor temperature is in the third temperature range, indicating that the room temperature has exceeded the human comfort temperature, so the cooling function is turned on. Since the stove is at high power at this time, the high room temperature combined with the stove's heat load will cause the room temperature to rise significantly. In order to avoid this phenomenon, in addition to using the high cooling setting, the air supply component is also moved to a lower position - the first height - to prioritize cooling the stove area, thereby reducing the heat and dryness of the stove area for users and improving the user experience.

[0107] As can be seen, the embodiments of the present invention, through the above-mentioned scheme of achieving corresponding control based on three temperature ranges, can perform corresponding environmental adjustment and control for more different scenarios, making the air conditioning effect more closely match the actual environmental needs, thereby better improving the user experience.

[0108] In some embodiments, to improve indoor environmental comfort in low-temperature environments, the present invention also provides a corresponding control scheme for a kitchen air conditioning unit including a heating mechanism. That is, the kitchen air conditioning unit control method provided in the present invention may further include:

[0109] In step S600, when the indoor temperature is lower than the minimum value in the first temperature range, the heating mechanism is controlled to operate, and the lifting drive mechanism is controlled to drive the air supply assembly to move to the first height or the second height.

[0110] Thus, through step S600, when the indoor temperature is low, such as in winter, hot air can be delivered to the kitchen, which can not only raise the indoor temperature to a certain extent, but also accelerate the fermentation of flour and dry the damp countertop and hands.

[0111] Furthermore, when the kitchen air conditioning equipment also includes a fresh air fan, the kitchen air conditioning equipment control method provided in this embodiment of the invention can further turn on the fresh air fan in step S600, so that the airflow drawn from the outside by the fresh air fan and the airflow drawn from the inside by the circulating fan are mixed in the first cavity before being sent out to the kitchen through the air supply component, which can improve the oxygen level in the kitchen.

[0112] In some embodiments, for kitchen air conditioning units that include a fresh air fan, to maximize the effectiveness of the fresh air fan and further improve indoor environmental comfort, please refer to... Figure 15, Figure 15 This is a flowchart of another kitchen air conditioning equipment control method provided in an embodiment of the present invention. The kitchen air conditioning equipment control method provided in an embodiment of the present invention may further include:

[0113] In step S700, the outdoor temperature of the kitchen area is obtained;

[0114] In step S810, when the indoor temperature is within a first temperature range and the gas flow rate is non-zero, if the outdoor temperature is within a first outdoor temperature range, the fresh air fan is controlled to operate at a low fresh air setting; if the outdoor temperature is within a second outdoor temperature range, the operating status of each mechanism remains unchanged; and / or

[0115] In step S820, when the indoor temperature is within the second temperature range and the gas flow rate is non-zero, if the outdoor temperature is within the first outdoor temperature range, the fresh air fan is controlled to operate at a low fresh air setting; if the outdoor temperature is within the second outdoor temperature range, the operating status of each mechanism is maintained; and / or

[0116] In step S830, when the indoor temperature is within a third temperature range and the gas flow rate is less than or equal to a non-zero set flow rate threshold, if the outdoor temperature is within a first outdoor temperature range, the fresh air fan is controlled to operate at a high fresh air setting; if the outdoor temperature is within a second outdoor temperature range, the fresh air fan is controlled to operate at a low fresh air setting; and / or

[0117] In step S840, when the indoor temperature is within the third temperature range and the gas flow rate is greater than a non-zero set flow rate threshold, if the outdoor temperature is within the first outdoor temperature range, the fresh air fan is controlled to operate at the high-speed fresh air setting; if the outdoor temperature is within the second outdoor temperature range, the operating status of each mechanism currently in operation is maintained.

[0118] The first outdoor temperature range includes the first temperature range and the second temperature range; the second outdoor temperature range and the third temperature range are the same. That is, the first outdoor temperature range is (20℃, 28℃), and the second outdoor temperature range is (28℃, +∞).

[0119] The steps S810 to S840 above all integrate indoor temperature, outdoor temperature, and gas flow to control the kitchen air conditioning equipment, so that the kitchen environment can be better and more appropriately adjusted.

[0120] In step S810, when the indoor temperature is within a first temperature range and the gas flow rate is non-zero, if the outdoor temperature is within a first outdoor temperature range, the fresh air fan is controlled to operate at a low fresh air setting. When the gas flow rate is less than or equal to the aforementioned flow rate threshold, it can increase oxygen levels in the stove area; when the gas flow rate is greater than the flow rate threshold, it can cool the stove area. Therefore, it is not necessary to differentiate between gas flow rates for separate control, but different effects can be achieved under different gas flow rates. If the outdoor temperature is within a second outdoor temperature range, the operating status of all currently running mechanisms is maintained, and the fresh air fan is not turned on, preventing the fresh air fan from bringing in higher-temperature gas and causing the indoor temperature to rise.

[0121] For step S820, when the indoor temperature is within the second temperature range and the gas flow rate is not zero, if the outdoor temperature is within the first outdoor temperature range, the fresh air fan is controlled to run at a low speed to cool the stove area; if the outdoor temperature is within the second outdoor temperature range, the operating status of each mechanism is maintained and the fresh air fan is not turned on to prevent the fresh air fan from bringing in higher-temperature gas and causing the indoor temperature to rise.

[0122] For step S830, when the indoor temperature is within the third temperature range and the gas flow rate is less than or equal to a non-zero set flow rate threshold, if the outdoor temperature is within the first outdoor temperature range, the fresh air fan is controlled to operate at the high-speed fresh air setting, which can assist in cooling and increasing oxygen in the room; if the outdoor temperature is within the second outdoor temperature range, the fresh air fan is controlled to operate at the low-speed fresh air setting, which can increase oxygen in the room while preventing the indoor temperature from rising due to the introduction of too much high-temperature airflow caused by turning on the high-speed fresh air setting.

[0123] For step S840, when the indoor temperature is within the third temperature range and the gas flow rate is greater than a non-zero set flow rate threshold, if the outdoor temperature is within the first outdoor temperature range, the fresh air fan is controlled to operate at the high-speed fresh air setting, which can assist in cooling and increasing oxygen in the room; if the outdoor temperature is within the second outdoor temperature range, the operating status of each mechanism is maintained, and the fresh air fan is not turned on, which can prevent the fresh air fan from bringing in gas with a higher temperature, thus causing the indoor temperature to rise.
