Description

Technical Field

[0001] The invention relates to a kitchen air conditioning method, a kitchen air conditioning system and a storage medium. Background Art

[0002] Stuffy, humid, and odors have always been a pain point in kitchens. Besides ambient temperature, the high air volume of kitchen range hoods, which requires a large amount of make-up air, contributes to the stuffiness. Gas combustion, human consumption, oxygen deficiency in the kitchen, and excessive combustion exhaust gases can also contribute to the stuffiness. Conventional methods address kitchen heat and humidity by installing air conditioners and opening windows for ventilation, while using range hoods to ventilate the air and address kitchen air quality issues. Air conditioners pose problems such as fume pollution and low usage frequency. Opening windows for ventilation cannot fundamentally address the range hood air supply issue. For example, on rainy days, during hot summers, or during cold winters, windows are rarely opened, rendering the air supply issue unresolved. The only solution to poor kitchen air quality is one-way ventilation from the range hood. However, the exhaust air is not replenished, leaving the kitchen under negative pressure. Replenishment is either drawn from other rooms like the living room or from windows. However, the air outside windows is unpurified and not fresh air, potentially containing high levels of PM2.5 or CO2.

[0003] The Chinese utility model patent "Kitchen Air Conditioning System" with authorization announcement number CN217004736U (application number 202122793175.0) discloses a kitchen air conditioning system that can only simply output cold air and hot air, and then adjust the air temperature in the kitchen. It cannot perform multi-directional adjustments based on the specific environmental conditions and usage conditions of the kitchen, and cannot achieve a constant temperature, constant humidity, constant oxygen, and constant cleanliness.

[0054] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0055] like Figure 1As shown, a kitchen air conditioning system according to this embodiment is installed in the kitchen. The kitchen air conditioning system includes a first air duct 1, a second air duct 2, a first air conditioning module 3 for heat dissipation and exhaust, a second air conditioning module 4 for supplying air into the kitchen, and a return air vent 5 that is switchably connected to the first and second air ducts 1 and 2. The system also includes a controller and a memory. The controller is electrically connected to the memory, the first and second air conditioning modules 3 and 4. The memory stores control instructions, which the controller can read and execute to implement the kitchen air conditioning method described below.

[0056] The first air channel 1 and the second air channel 2 are isolated from each other. To facilitate coordinated operation, the kitchen air conditioning system in this embodiment includes a housing 6. A partition is provided within the housing 6 to separate the space within the housing 6 into two independent spaces, thereby forming the first air channel 1 and the second air channel 2. The first air channel 1 and the second air channel 2 are both provided with an inlet and an outlet, thereby allowing airflow. The inlet and outlet of the first air channel 1 are respectively connected to the external environment, the inlet of the second air channel 2 is connected to the external environment, and the outlet of the second air channel 2 is connected to the kitchen space. Specifically, the inlet of the first air channel 1 is connected to the external environment through a first tube body 10, and the inlet of the second air channel 2 is connected to the external environment through a second tube body 20. The first tube body 10 is provided with a first valve body 101 that can open and close the first tube body 10, and the second tube body 20 is provided with a second valve body 201 that can open and close the second tube body 20. In this way, the opening and closing of the inlets of the first air channel 1 and the second air channel 2 can be controlled by controlling the opening and closing of the first valve body 101 and the second valve body 201. When the first valve body 101 and the second valve body 201 are opened, the first air channel 1 and the second air channel 2 can introduce air from the external environment.

[0057] The first air conditioning module 3 is disposed within the first air passage 1, and the second air conditioning module 4 is disposed within the second air passage 2. In this embodiment, the first air conditioning module 3 and the second air conditioning module 4 utilize conventional air conditioning components and operate according to the conventional air conditioning operating principles. Furthermore, some non-air conditioning components are additionally provided based on requirements such as fresh air demand and air outlet temperature. Specifically, the first air conditioning module 3 includes a compressor 31, a condenser 32, and a first fan 33, which are connected in sequence. The air outlet of the first fan 33 is connected to the outlet of the first air passage 1. Consequently, under the action of the first fan 33, air can be exhausted and heat dissipated outward through the first air passage 1.

[0058] The second air conditioning module 4 comprises a second fan 41 and an evaporator 42, connected in sequence, as well as an air purification component 43 and an air heating module 44. While the second fan 41 and evaporator 42 are conventional air conditioning components, this embodiment incorporates an additional air purification component 43 to purify incoming air, thereby delivering fresh air. Furthermore, an air heating module 44 is provided to heat the fresh air according to desired temperature, preventing a significant temperature difference between the fresh air delivered and the air inside the kitchen, which could affect the kitchen's temperature. This effectively maintains temperature stability within the kitchen, particularly in winter.

[0059] The air purification component 43 is disposed at the inlet of the second air passage 2, thereby purifying the air entering the external environment immediately, so that the airflow processed by the second air conditioning module 4 is also purified fresh air, thereby outputting cleaner air into the kitchen space. The air purification component 43 can adopt various air purification component 43 structures in the prior art, such as the air purification component 43 structure of various fresh air blowers.

[0060] In this embodiment, the second fan 41 is disposed at the inlet of the second air duct 2, with the outlet of the second fan 41 facing the inlet of the second air duct 2. The outlet of the second fan 41 is connected to the inlets of the evaporator 42 and the air heating module 44 via a three-way pipe 45. The evaporator 42 and the air heating module 44 are connected to the kitchen space, forming the air conditioning outlet 21 and the fresh air outlet 22, respectively. To effectively control the opening and closing of the air conditioning outlet 21 and the fresh air outlet 22, a third valve 451 is provided within the three-way pipe 45 in this embodiment to adjust the connection between the second fan 41 and the evaporator 42 or the air heating module 44. By adjusting the third valve 451, the outlet of the second fan 41 can be connected only to the air heating module 44, thereby outputting only fresh air; or the outlet of the second fan 41 can be connected to both the air heating module 44 and the evaporator 42, thereby outputting both fresh air and air conditioning air.

[0061] The return air vent 5 is located within the air outlet space at the junction of the first air duct 1 and the second air duct 2. A fourth valve body 51 is provided within the return air vent 5, which can open the first air duct 1, open the second air duct 2, or close the return air vent 5. Based on the control of the fourth valve body 51, when the return air vent 5 is opened and thus connected to the first air duct 1, the dirty air in the kitchen space can be discharged through the first air duct 1. When the return air vent 5 is connected to the second air duct 2, the air flow in the kitchen space is circulated internally, which can reduce energy consumption particularly in summer.

[0062] In addition, in order to facilitate the more uniform and convenient output of the air-conditioning outlet 21 and the fresh air outlet 22 to the kitchen space, the kitchen air conditioning system can also be additionally provided with an air outlet component 7 connected to the air-conditioning outlet 21 and the fresh air outlet 22. The air outlet component 7 can be an air outlet network structure commonly configured for air conditioners in the prior art.

[0063] A range hood is typically installed in the kitchen to extract cooking fumes. The kitchen air conditioning system can be independently installed within the kitchen, for example, embedded in the kitchen ceiling, with the air outlet assembly 7 exposed to discharge air into the kitchen. The kitchen air conditioning system is embedded in the range hood. To facilitate intelligent linkage with the range hood, the kitchen air conditioning system also includes a wireless communication module electrically connected to the controller, enabling communication with the range hood and coordinated operation.

[0064] The kitchen air conditioning system works by adopting a kitchen air conditioning method.

[0065] Specifically, the kitchen air conditioning method includes:

[0066] When the kitchen is in use, the second air conditioning module 4 is controlled to work to output fresh air after air filtering into the kitchen space;

[0067] When the kitchen is in use, the first air conditioning module 3 and the second air conditioning module 4 are controlled to operate based on the temperature difference between the inside and outside of the kitchen space, so as to adjust the air conditioning air with matching temperature to be delivered into the kitchen space.

[0068] In addition, when the external ambient temperature is low, such as in winter, if the first air duct 1 directly introduces external ambient air and outputs fresh air, the air with too low external ambient temperature will affect the temperature in the kitchen space, causing the temperature in the kitchen space to drop. When the kitchen is in use, the air heating module 44 is controlled to work based on the temperature difference between the inside and outside of the kitchen space, thereby heating the fresh air so that the temperature of the air output to the kitchen space matches the temperature in the kitchen.

[0069] In addition, the fourth valve body 51 is controlled as needed to open the return air vent 5. Specifically, the return air vent 5 is controlled to open the connection with the first air duct 1 and the first air conditioning module 3 is controlled to operate to exhaust the exhaust gas in the kitchen, or the return air vent 5 is controlled to open the connection with the second air duct 2 and the second air conditioning module 4 is controlled to circulate the air in the kitchen.

[0070] In order to ensure the air pressure balance, when the return air vent 5 is controlled to be opened, if the second air-conditioning module 4 outputs air-conditioning air at the same time, the air volume Q1 of the air-conditioning air is calculated and the exhaust volume Q2 of the range hood in the kitchen is calculated, and the fourth valve body 51 is controlled to operate to adjust the opening of the connection between the return air vent 5 and the second air channel 2 to meet the ratio of the return air volume of the return air vent 5 to the air intake volume of the second air channel 2 of Q1 / Q2, and at the same time adjust the working parameters of the second air-conditioning module 4 so that the air outlet volume Q of the second air-conditioning module 4 is Q=Q1+Q2; otherwise, the fourth valve body 51 is controlled to operate to adjust the opening of the connection between the return air vent 5 and the first air channel 1 so that the return air volume of the return air vent 5 matches the fresh air volume.

[0071] According to the working content of the kitchen air conditioning system, in this embodiment, the first working mode, the second working mode, the third working mode, the fourth working mode, the fifth working mode, and the sixth working mode can be formed based on the different working content combinations of the kitchen air conditioning system. Figures 3 to 8 shown.

[0072] The working method of the first working mode is: when the kitchen is in use, the second air conditioning module 4 is controlled to work, and fresh air and cold air-conditioned air are output to the kitchen space through the second air channel 2; at the same time, the first air conditioning module 3 is controlled to work, and heat and exhaust air outward through the first air channel 1.

[0073] The working method of the second working mode is: when the kitchen is in use, the second air-conditioning module 4 is controlled to work, and fresh air is output to the kitchen space through the second air channel 2. At the same time, the second air-conditioning module 4 is controlled to work, and the return air port 5 is controlled to open and connect with the second air channel 2. The return air entering the second air channel 2 through the return air port 5 is output to the kitchen space based on the work of the second air-conditioning module 4; at the same time, the first air-conditioning module 3 is controlled to work, and heat and exhaust air to the outside through the first air channel 1.

[0074] The working method of the third working mode is: when the kitchen is in use, the second air conditioning module 4 is controlled to work, and heated fresh air is output to the kitchen space through the second air channel 2.

[0075] The working method of the fourth working mode is: when the kitchen is in use, the second air-conditioning module 4 is controlled to work, and heated fresh air is output to the kitchen space through the second air duct 2; at the same time, the first air-conditioning module 3 is controlled to work, and the return air outlet 5 is controlled to open and connected to the first air duct 1. The return air in the kitchen enters the first air duct 1 through the return air outlet 5 and is exhausted to the outside based on the operation of the first air-conditioning module 3.

[0076] The working method of the fifth working mode is: when the kitchen is in use, the second air conditioning module 4 is controlled to work and output fresh air into the kitchen space through the second air channel 2.

[0077] The working method of the sixth working mode is: control the second air conditioning module 4 to work, and output fresh air to the kitchen space through the second air duct 2; at the same time, control the first air conditioning module 3 to work, control the opening of the return air outlet 5 to connect with the first air duct 1, and the return air in the kitchen enters the first air duct 1 through the return air outlet 5 and is exhausted to the outside based on the work of the first air conditioning module 3.

[0078] The kitchen air conditioning method includes several working modes, such as Figure 2 As shown, the kitchen air conditioning method can be performed using the following steps S1 to S7.

[0079] S1. Detect whether there is anyone in the kitchen; infrared sensors, cameras and other equipment can be used for detection as needed.

[0080] If not, it means that the kitchen is not in use. At this time, it is only necessary to monitor the air quality in the kitchen space to avoid poor air quality in the kitchen space. When the user enters, it cannot be adjusted to a high-quality air quality state in time, which affects the user experience and even affects the user's health. In this case, S2 is performed; if yes, it means that the kitchen is in use. In this case, based on the different work content of the users in the kitchen, the kitchen air conditioning system is controlled to achieve the purpose of constant temperature, constant humidity, constant oxygen, and constant cleanliness. In this case, S3 is performed.

[0081] S2. Detect the air quality in the kitchen. Specific detection items are set as needed, and corresponding detection devices are set. For example, parameters such as PM2.5 concentration, CO2 concentration, smoke concentration, humidity, etc. in the kitchen space can be detected. Thresholds corresponding to each detection data are also set accordingly, and then comparative judgments are made to obtain the air quality in the kitchen space. Specifically, determine whether the air quality in the kitchen meets the set requirements; if so, detect the air quality in the kitchen according to the set detection cycle; if not, control the operation according to the sixth working mode, that is, perform fresh air ventilation in the kitchen. Based on the sixth working mode, the air in the external environment is purified by the air purification component 43 in the second air channel 2, and fresh air is output from the fresh air outlet 22. Since there is no one in the kitchen, there is no need to adjust the temperature, so this step is suitable for the application scenario of daily fresh air ventilation in the kitchen space.

[0082] S3. Detect the air temperature T outside the kitchen, detect the air temperature T0 inside the kitchen, calculate the temperature difference ΔT=|T-T0|, and compare ΔT with a preset temperature difference threshold ΔT0.

[0083] If ΔT<ΔT0, it means that the temperature difference between the inside and outside of the kitchen space is not large, which is usually the case in spring and autumn, and then proceed to S4; if ΔT≥ΔT0, it means that the temperature difference between the inside and outside of the kitchen space is relatively large, which is usually the case in summer or winter, and then proceed to S5.

[0084] S4. Detect the user's position in the kitchen. If the user is in the cooking area, usually in the cooking working state, based on the temperature judgment in S3, the control is correspondingly controlled to operate in the fifth working mode, that is, the temperature difference between the inside and outside of the kitchen space is not large and the current temperature is relatively comfortable in spring and autumn. At this time, only the second air channel 2 is controlled to be conductive, and the second fan 41 is controlled to be connected to the air heating module 44, and the air heating module 44 does not need to work. Then, the air in the external environment is purified by the air purification component 43 in the second air channel 2 to form fresh air, and then output from the fresh air outlet 22 to the kitchen space, that is, only fresh air is output to the kitchen space, so that the range hood is used to replenish air in the cooking state, avoiding the negative pressure in the kitchen space, and thus meeting the air conditioning needs in the kitchen. This step is applicable to the spring and autumn cooking application scenario in the kitchen space.

[0085] If the user is not in the cooking area, it means that the user is performing non-cooking tasks in the kitchen, such as preparing food. Based on the temperature judgment in S3, the control operates according to the sixth working mode, that is, the second valve body 201 is controlled to open, the second control module is controlled to operate to output fresh air into the kitchen space through the second air channel 2, and the return air vent 5 is controlled to open and the fourth valve body 51 is controlled to operate, thereby connecting the return air vent 5 with the first air channel 1, thereby exhausting the dirty exhaust gas in the kitchen space, realizing fresh air ventilation in the kitchen, and improving the air quality when the user is in the kitchen. This step is suitable for the application scenario of preparing food in the kitchen space in spring and autumn.

[0086] S5. Compare T with T0. If T>T0, it means that the external ambient air temperature is high, which is usually the case in summer. In this case, proceed to S6. If T≤T0, it means that the external ambient air temperature is low, which is usually the case in winter. In this case, proceed to S7.

[0087] S6. Detect the user's position in the kitchen. If the user is in the cooking area, the user is usually cooking. Combined with the temperature in S5, it can be determined that the current application environment is a summer cooking application environment, which requires cooling. At the same time, the air in the kitchen is largely drawn away by the range hood. At this time, the cooling capacity is usually unable to meet such a large air supply requirement, so a large amount of fresh air ventilation is required to ensure that the air in the kitchen is not in a negative pressure state. Based on this, the control operates in accordance with the first working mode, outputting fresh air and cold air-conditioning air into the kitchen space while dissipating heat and exhausting air outward. Specifically, the control opens the first valve body 101 and the second valve body 201, allowing the outside air to enter the first air channel 1 and the second air channel 2, and controls the third valve body 451 to operate to achieve conduction between the second fan 41 and the air heating module 44 and the evaporator 42, and only controls the evaporator 42 to operate, thereby outputting normal temperature fresh air from the fresh air outlet 22 while outputting cold air-conditioning air based on the operation of the evaporator 42. At the same time, based on the state of the fourth valve body 51, the return air port 5 is ensured to be in a closed state, and the compressor 31, the first fan 33, and the condenser 32 are controlled to work, and then the outside air is output through the first air channel 1, thereby realizing exhaust and heat dissipation, which ensures that the heat dissipation air only enters from the outside and the exhaust air is discharged to the outside.

[0088] If the user is not in the cooking area, it indicates that the user is performing non-cooking tasks in the kitchen, such as preparing food. Based on the temperature determination in S5, it is determined that the current scenario is summer food preparation. In this scenario, a small amount of fresh air ventilation is required to ensure fresh air in the kitchen space. At the same time, the kitchen air circulation mode can be controlled to operate, that is, the air passing through the evaporator 42 can be returned from the room to reduce machine energy consumption. Accordingly, the second operating mode is operated, that is, the second valve body 201 is controlled to open to connect the second air channel 2, the third valve body 451 is controlled to operate to connect the second fan 41 with the air heating module 44 and the evaporator 42, and the air heating module 44 is controlled to be in the non-operating state. The fourth valve body 51 is controlled to operate to connect the return air port 5 with the second air channel 2, thereby outputting fresh air into the kitchen space and realizing internal circulation of the kitchen air to output cold conditioned air. In addition, the first valve body 101 is controlled to operate to open the first air channel 1, and the compressor 31, the first fan 33, and the condenser 32 are controlled to work simultaneously, thereby dissipating heat and exhausting air outward. The heat dissipation air only enters from the outside, and the exhaust air is discharged to the outside.

[0089] S7: Detect the user's location in the kitchen. If the user is in the cooking area, they are typically cooking. Combined with the temperature in S5, it can be determined that the current application environment is a winter cooking environment. During cooking, the range hood in the kitchen is typically turned on. When supplying fresh air, the air heating module 44 is required to heat the fresh air to reduce the temperature difference between the fresh air and the indoor temperature. In this manner, the control operates in the third operating mode, outputting heated fresh air into the kitchen. Specifically, the first air channel 1 is closed, the second valve body 201 is controlled to operate, causing the second air channel 2 to open. The third valve body 451 is controlled to connect the second fan 41 to the air heating module 44, and the air heating module 44 is controlled to operate, thereby outputting heated fresh air into the kitchen space to avoid the negative pressure caused by the operation of the range hood during cooking.

[0090] If the user is not in the cooking area, it means that the user is performing non-cooking tasks in the kitchen, such as preparing food. Based on the temperature determination in S5, it is determined that the current scenario is winter food preparation. At this time, the range hood is off. To ensure fresh air in the kitchen, the fresh air ventilation function needs to be turned on. At this time, due to the large temperature difference between the inside and outside spaces, while the first air channel 1 is connected and the second fan 41 is connected to the air heating module 44, the second fan 41 and the air heating module 44 are controlled to operate simultaneously, thereby introducing heated fresh air into the kitchen space. At the same time, it is necessary to discharge the indoor exhaust air to the outside. In other words, the return air vent 5 is connected to the first air channel 1, and the first fan 33 is controlled to operate to discharge the exhaust air in the kitchen space. In other words, the range hood is controlled to operate in the fourth operating mode, outputting heated fresh air into the kitchen space while discharging the exhaust air in the kitchen through the return air vent 5.

[0091] In order to meet the personalized needs of users, after the working mode is determined, it is detected whether the user's operating instructions for operating the kitchen air conditioning system are obtained within the set time N. If so, the kitchen air conditioning system is controlled to work according to the user's operating instructions; if not, the kitchen air conditioning system is controlled to work according to the determined working mode.

[0092] In addition, in order to ensure the air pressure balance, in the working method of the first working mode, the air volume Q3 of the cold air-conditioning air is calculated according to the temperature difference between the temperature in the kitchen and the set comfort temperature, and the exhaust volume Q4 of the range hood in the kitchen is calculated. The ratio of the output cold air-conditioning air volume to the fresh air volume is controlled to be Q3 / Q4, and at the same time, the working parameters of the second air-conditioning module 4 are adjusted so that the air volume Q of the second air-conditioning module 4 is Q=Q3+Q4.

[0093] The kitchen air conditioning method of the present invention, based on the structure of the kitchen air conditioning system, can not only input temperature-matched conditioned air into the kitchen space to adjust the temperature within the kitchen space, but also introduce fresh air from outside into the kitchen space. This not only solves the problems of stuffiness and poor air quality in the kitchen space, but also solves the problem of negative pressure in the kitchen space due to the range hood, which requires fresh air. This achieves the goals of constant temperature, humidity, oxygen, and cleanliness in the kitchen space.

[0094] The present invention also relates to a computer-readable storage medium, wherein the computer-readable storage medium stores computer instructions, and the computer instructions are used to enable a computer to execute the aforementioned kitchen air conditioning method.
