Description

Partition surrounding air supply control method of kitchen air conditioner

Technical Field

The invention relates to a partition surrounding air supply control method of a kitchen air conditioner.

However, a kitchen is generally divided into a cooking area and a cooking area, and a user processes food materials in the cooking area and then moves to the cooking area to cook the food materials. Moreover, due to the different distances from the heat source, the user's needs for temperature are different in the cooking and cooking zones. When the cooking area is close to the fire source, the user hopes that the air supply of the air conditioner is cooler and the air volume is stronger. On the contrary, when the user is in the cooking area, the user is far away from the fire source, so the requirements on the temperature and the air volume are not particularly strong, and the user only needs to use the cooking area. That is, if the air is supplied to the cooking zone user in accordance with the air volume and temperature of the cooking zone, the user tends to feel too cold and get cool, and if the air is supplied to the cooking zone user in accordance with the air volume and temperature of the cooking zone, the user tends to feel not cool and dry.

(method for judging position of small-space host machine in kitchen and toilet)

In order to control different areas of the small space, it is necessary to set various control parameters (such as the air blowing direction, the air blowing amount, and the air blowing temperature) in the operation mode or the secondary operation mode based on the position of the main unit of the air conditioner with respect to the different areas of the small space, that is, to locate the main unit of the air conditioner. The basic principle of the positioning method of the main unit of the air conditioner is as follows.

The basic parameters of the small space are preset in the air conditioner, and certain initial air supply parameters are set.

When the air conditioner is started to supply air, the air supply of the air conditioner is rebounded by different wall surfaces of the small space and returns to the air return opening of the air conditioner, and the air supply motor drives the fan to enable the air to be supplied to the air outlet of the air conditioner through the air supply loop in the air conditioner. When the air is blown out, the air volume returned to the return air inlet of the air conditioner is different. In order to ensure that the air volume of the air outlet of the air conditioner is constant, the rotation speed of the air supply motor (power is increased) is required to make up the air volume lost due to on-way resistance, and therefore the position of the air conditioner can be judged according to the power increase percentage of the air supply motor.

When the path of the air outlet of the air conditioner returning to the air return inlet from the air outlet is completely free of the shielding object, the air outlet volume and the air return volume of the air conditioner can not cause air volume loss due to on-way resistance loss correspondingly. When the angle of the air outlet is changed, the air outlet volume and the air return volume of the air conditioner are set values (reference values), and the air conditioner is limited by the size of a small space due to the fact that the air conditioner is arranged in the small space, and the air flow of the air outlet is subjected to resistance along the way when flowing along the set direction. In this case, the return air volume is smaller than the reference air volume value (a certain percentage of the reference value) set without the shutter. The air conditioner generates a control signal according to the air volume percentage, and the control signal is fed back to the fan motor to enable the power of the fan motor to be changed. The air conditioner can determine the position of the air conditioner according to the values (power change values) before and after the change of the rotating speed of the fan motor, the collected air physical parameters (the physical parameters comprise the temperature, the humidity, the density, the specific heat capacity and the like of air), the blowing angle and the size of a toilet in the current environment.

Referring to fig. 3, a method for positioning a main unit of an air conditioner will be described. Fig. 3 is an explanatory diagram showing a method of determining the position of the kitchen and bath small space master. The small space in fig. 3 is divided into a first zone and a second zone. The partition shown in fig. 3 is merely an example, and is not limited to two areas, and may be three or more areas.

First, the space size of the small space is set in the initialization program of the air conditioner. The space size includes length, width and height.

Then, the air conditioner determines the position of itself in the small space in the direction of the front and rear air blowing. Specifically, as shown in the left diagram of fig. 3, the blade 23 for left and right air blowing of the air conditioner is set to be centered in the initialization routine, and the air direction of the air blowing is controlled only by the blade 23 for up and down air blowing, and at this time, the up and down air blowing angle and the air blowing amount of the air conditioner are set (the maximum range in which the air blowing angle α can be set is 0 ° to-90 °). When the angle is selected too small, the air supply volume is small and the test accuracy is insufficient, and when the angle is selected too large, the air flow scattering degree is too large and the test accuracy is also insufficient. Therefore, it is preferable that the upper and lower air supply angles are two air supply angles of 30 ° and 60 °, respectively (the two angles are designed air supply angles that most air conditioners can achieve in normal use and in general air conditioners). The relative position of the air conditioner in the front and rear air supply direction, that is, the position of the air conditioner from the front and rear walls is located by detecting the percentage value of the power rise of the fan motor at both air supply angles of 30 ° and 60 °.

Then, the air conditioner determines the position of itself in the small space in the direction of the left and right air blowing. Specifically, as shown in the right-hand diagram of fig. 3, the blade 23 for the air-conditioning upper and lower air blowing is set to be centered in the initialization routine, and the angle of the air blowing is controlled only by the blade 23 for the left and right air blowing, and at this time, the left and right air blowing angles and the air blowing amount of the air-conditioning are set (the maximum range in which the air blowing angle α can be set is 0 ° to-90 °). As in step S12, it is preferable that the left and right air blowing angles are two air blowing angles of 30 ° and 60 °, respectively. The relative position of the air conditioner in the direction of the left and right air supply (i.e., the position of the air conditioner from the left and right walls) is located by detecting the percentage value of the power rise of the fan motor at both the air supply angles of 30 ° and 60 °.

Therefore, the position of the air conditioner in the small space can be detected, and the position data is stored in the memory 7 and the cloud server 9 for subsequent setting and control.

(kitchen and toilet small space partition environment keeping control method)

In order to maintain the environment of a small space in a partitioned manner such as a kitchen, a toilet and the like, a kitchen and toilet small space partitioned environment maintaining control method is designed.

Next, a method for keeping and controlling the partitioned environment in the small space of the kitchen and the toilet will be specifically described.

In the method, the set parameters comprise: (1) the operation mode is a main mode of the air conditioner operation, including temperature rise and temperature reduction; (2) target partition, i.e. a certain partition which is pre-designated automatically or manually; (2) the operation air volume, namely the air volume mode and the air volume value of the air conditioner operation, comprises high air volume (75-100% of the total capacity), medium air volume (33-74% of the total capacity), low air volume (5-32% of the total capacity), and the air volume value in each air volume mode can be a specific value.

The specific flow of the kitchen and bathroom small space partition environment keeping control method is as follows.

First, a pretreatment is performed. The pretreatment is only needed to be executed once when being matched with the installation of an air conditioner. The pretreatment includes the following three aspects. The description will be made by taking a toilet as an example.

(1) And acquiring horizontal and vertical position information of the air conditioner according to a 'kitchen and bathroom small space host position judgment method'. The horizontal and vertical position information of the air conditioner may be manually set by a user or an installer. The cloud server 9 may also perform big data analysis to obtain the horizontal and vertical position information of the air conditioner. The horizontal and vertical position information of the air conditioner can be obtained by a laser distance sensor of the air conditioner.

(2) According to the 'horizontal and vertical position information of the air conditioner', for each target subarea, the pointing direction from the air conditioner to the target subarea with the air conditioner as the center of the sphere is calculated. The pointing direction of each target partition can also be obtained by a laser distance sensor of the air conditioner.

The positioning of the kitchen and bathroom air conditioner can be implemented by the method for judging the position of the small-space host computer in the kitchen and the bathroom. When each partition of the toilet is confirmed, each partition of the toilet can be selected in a display area of the external controller 8 of the air conditioner, the partition setting is set in a program in advance, and a user can select a proper partition mode according to the layout of the actual toilet. The partition mode selected by the user can be realized by selecting the spatial layout mode through a secondary menu. After confirming the air conditioner position and the layout of the toilet subareas, the direction of the air supply of each subarea by the air conditioner can be determined. According to the space position of the air conditioner and the wind direction of the air supply and exhaust of the air conditioner, the air supply and exhaust is rebounded by the wall surface and returns to the air return opening of the air conditioner after passing through the partition to be conveyed. Because the path of the air sent and exhausted has trigonometric function relation in the toilet space, the air supply angle of the air conditioner can be accurately controlled, and the air processed in the air conditioner is directionally sent to different subareas through the action of the air conditioner blades.

Take the case of dividing the toilet into four zones and supplying air to the toilet zone by the air conditioner. Fig. 4 is a schematic view of the path of the supply air for supplying air to the toilet bowl area. As shown in fig. 4, when the user selects to supply air to the toilet area at the external controller 10, the air conditioner automatically adjusts the direction of the blades, and the air of the air conditioner returns to the air return opening through the kitchen and toilet space.

(3) The position of the air conditioner in the toilet is known, and the blade angle in the case of the partition is also confirmed, and the temperature rise rate and the temperature fall rate of different partitions are set according to the change along with the outdoor environment. Namely, under the conditions that the outdoor temperature is relatively low in winter, relatively warm in spring and autumn and relatively hot in summer, the control processes of the heating rate and the cooling rate of the corresponding subarea are different, and the heating rate and the cooling rate are mainly in direct relation with the change of the frequency of the outdoor variable frequency compressor of the air conditioner along with the time.

In winter, the outdoor environment temperature is-20 ℃ to 10 ℃, the safety of the air conditioner operation is very important due to the low outdoor environment temperature, the pressure of the refrigerant in the whole system is relatively low, the fluidity of the compressor lubricating oil at low temperature is poor, the refrigerant and the lubricating oil cannot be well dissolved mutually at the moment, and the heat exchange efficiency is low. Therefore, the compressor is preheated for a period of time, so that the refrigerant and the lubricating oil flow through internal circulation for a period of time, the indoor fan is started in a delayed mode, and the frequency of the compressor is gradually increased by adopting a step-by-step frequency increasing mode to warm the toilet. The time-dependent temperature rise rate in the toilet is shown in fig. 5, and the safety of the compressor from the start to the stable operation can be ensured. Furthermore, when the air conditioner is operated in the winter season, attention is particularly paid to the case where the outdoor ambient temperature is particularly low. When the outdoor environment temperature is very low, the compressor is difficult to start, the pressure of the air suction port of the compressor needs to be paid special attention at this moment, and when the compressor runs at ultra-low temperature, if the pressure of the air suction port is too low, the frequency of the compressor should be properly reduced to meet the safe running of the air conditioner.

In spring and autumn, the outdoor environment temperature is 10-20 ℃. Because outdoor ambient temperature is moderate relatively, the body feels warm, so the restriction of compressor start-up this moment is less, and the compressor can directly start-up promptly, need not take hierarchical mode of raising frequency, can take the quick mode of raising frequency of straight line, can be according to the temperature that the user set for, and quick raising frequency guarantees user's experience and feels. The temperature rising rate and the temperature falling rate of the toilet are shown in the graphs of fig. 5 and 6 along with the time change.

In summer, the outdoor environment temperature is 20-40 ℃, and the limitation of the start of the compressor is less because the outdoor environment temperature is relatively hot, so that the indoor temperature can be quickly cooled by adopting a linear quick frequency increasing mode. However, when the frequency is increased to a certain value, the pressure of the refrigerant in the outdoor unit is high and the temperature of the discharge port of the compressor is also high, and the compressor needs to be operated in a frequency-reducing manner to ensure the safety of the air conditioner. A schematic diagram of the cooling rate of the toilet over time at this time is shown in fig. 6.

After the preprocessing, the following steps are performed each time the kitchen and bath small space partitioning environment keeping control method is operated.

(1) The pointing direction from the air conditioner to the target partition with the air conditioner as the center of sphere may be calculated in real time for each target partition based on "horizontal and vertical position information of the air conditioner" every time the kitchen and bath small space partition environment keeping control method is executed. Or the pointing direction of each target partition is obtained by a laser distance sensor of the air conditioner. That is, this step is performed when the kitchen and bath small space partitioning environment keeping control method is executed after the preprocessing, and is not performed in the preprocessing.

(2) And judging the running mode.

When the temperature is increased, the current environment mode is judged according to the indoor and outdoor temperature sensors and humidity sensors, or the current season, temperature and humidity information is acquired from the cloud end to judge the current environment mode.

When the mode is determined to be the spring and summer mode, the air-conditioning heating mode is turned on. At this time, the direction compensation value is corrected upward by 2 ° to 5 ° in the vertical direction so as to improve the user experience by utilizing the principle of the drop of the cool air.

When the mode is determined to be the autumn and winter mode, the air-conditioning heating mode is started. At this time, the direction compensation value is corrected by 2 to 5 degrees downward in the vertical direction, so that the use experience of the user is improved by using the principle that the hot air rises.

When the temperature is reduced, the current environment mode is judged according to the indoor and outdoor temperature sensors and the humidity sensor, or the current season, temperature and humidity information is acquired from the cloud end to judge the current environment mode.

When the mode is determined to be the spring and summer mode, the air-conditioning cooling mode is turned on. The direction compensation value is corrected to be 2-5 degrees upwards in the vertical direction so as to improve the use experience of a user by utilizing the principle of cold air descending.

When the mode is determined to be the autumn and winter mode, the air-conditioning heating mode is started. The direction compensation value is corrected to 2-5 degrees downwards in the vertical direction, so that the use experience of a user is improved by using the principle that hot air rises.

The above-described spring and summer mode and autumn and winter mode are merely names of modes and do not necessarily correspond to real seasons.

(3) And calculating the numerical value of the pointing direction of the air guide blade.

And the numerical value of the pointing direction of the wind guide blade is equal to the numerical value of the pointing direction of the target subarea plus the compensation value of the delta direction.

(4) And driving the air guide blades to point to the direction according to the numerical values of the pointing directions of the air guide blades.

(5) And starting an air supply motor, setting different operation powers according to the operation air quantity, and starting air supply according to the operation powers.

In addition, real-time feedback is also carried out when the control method for keeping the environment of the small space partition of the kitchen and the toilet is operated. The temperature of indoor outer temperature, humidity information and fine setting air supply can be obtained according to indoor outer temperature sensor and humidity transducer to realize comfortable user's body and feel the temperature. And the direction fine adjustment in a partition range can be realized by adjusting a delta direction compensation value through a human detection sensor.

As described above, the kitchen and bathroom small space partition environment keeping control method can calculate the matched air supply angle and automatically control the air conditioner according to the set mode, the designated partition and the running air volume, and can realize the surrounding type air flow circulation of the designated partition.

(control method for keeping regular environment in small space of kitchen and toilet)

In order to regularly maintain the environment of small spaces such as kitchens, toilets and the like, a regular environment maintaining control method for the small spaces of the kitchens and the toilets is designed.

The parameters required in the method include the time interval for the periodic start-up and the operating parameters for the periodic start-up.

The time interval of the regular start can be set by the user through the external controller 10 or the mobile phone APP, or can be automatically acquired from the cloud server 9 by the air conditioner, and the time interval of the regular start is set according to big data information such as region, season, temperature, humidity and the like.

The operating parameters of the regular start can be automatically acquired from the cloud server 9 by the air conditioner, and are set according to regions, seasons, temperatures, humidity and the like, including air volume, temperature and the like.

In the control method for maintaining the regular environment in the small space of the kitchen and the bathroom, whether the time interval is reached or not is automatically judged. When the time interval has not been reached, monitoring continues. And when the time interval is reached, operating the kitchen and bathroom air conditioner to perform dehumidification operation.

As described above, the periodic environmental conservation control method for the small space of the kitchen and the toilet can be automatically started periodically, so that the air conditioner can perform a corresponding environmental conservation program, thereby reducing the humidity in the small space range of the kitchen and the toilet and eliminating peculiar smell, controlling the temperature, and better realizing the effect of removing mildew.

The above description is of the special operation method of the air conditioner of the present invention, and the air conditioner of the present invention can naturally perform air direction and temperature control in the normal air-conditioning heating and cooling mode. These methods may be performed in different operating modes or in a secondary operating mode.

[ examples ]

The embodiment is a partition surrounding air supply control method of a kitchen air conditioner. Next, this embodiment will be explained.

(control method for small space partition surrounding blowing)

By the positioning method of the air conditioner host, the relative positions of the host of the air conditioner integrated with the ceiling plane relative to the front wall, the rear wall, the left wall and the right wall of a small space such as a toilet or a kitchen can be obtained. Taking a kitchen as an example, when the air conditioner is in a debugging stage, the information of relatively fixed dimensions such as the room size of the kitchen, the height range of family members, a table board, a cabinet and the like is initialized, and the upper position, the lower position, the left position and the right position of blades of an air outlet of the air conditioner are adjusted in a small space such as the kitchen, so that the effect of air supply of the air supply fluid surrounding the human body can be controlled, and the control method for performing the partitioned surrounding air supply on two areas such as a cooking area and a cooking area is realized.

The method is suitable for the condition that the user is in the cooking area or the cooking area for a long time. In this case, the mode may be turned on, and specifically, the user may manually turn on the cooking zone and the partitioned enclosure air supply control of the cooking zone by the wireless switching controller, or may determine to operate the method by detecting that a person is intensively active in a certain area for a certain time by using the person detection sensor.

Next, a method of adjusting the blowing angle for differentiating the surrounding blowing will be described.

Taking the centralized air supply to the cooking area as an example, the method for judging the enclosed air supply of the upper and lower angles of the air conditioner and the method for judging the enclosed left and right angles of the air conditioner are implemented and adjusted separately.

First, a method of determining the vertical angle of the air conditioner in the enclosed air blowing is taken as an example. In order to make the air blown to a human body more comfortable, the opening angle of the upper blade and the lower blade of the air conditioner is the upper optimal angle alpha and the lower optimal angle alpha, and the air is sent out and returns to the air return opening of the air conditioner through a certain air supply path. For the cooking area, the optimal air supply angle of the upper blade and the lower blade is selected to be the opening angle of the upper blade and the lower blade of the air conditioner, so that the air output by the air conditioner just can pass over the top of the head of a person on the front table board, and at the moment, the air output rebounds through the front wall surface, passes through the human body, and then rebounds through the ground and the rear wall and returns to the air return opening of the air conditioner. In the whole air supply loop of the air conditioner, a user is surrounded by cold air (hot air) and does not directly blow to the body of the user, and compared with the direct blowing, the human body feels more comfortable.

In the phase of performing initial debugging on the air conditioner, as shown in fig. 7, assuming that the width Y1 of the front and left panels to be blown by the air conditioner, the height X1 of the highest human body of the family member, the height X2 of the integrated ceiling from the ground, the distance Y of the air conditioner from the front wall, and as marked X3 in fig. 7 are inputted into the air conditioning system, it can be known from the trigonometric function relationship that:

according to the two relations: α ═ arctan (X2-X1)/(Y-Y1)

However, X1, X2, and Y, Y1 can be set at the commissioning stage of the air conditioner, and thus the vertical optimum angle α at which the vertical vanes of the air conditioner in the food area are opened can be immediately obtained.

Then, a method of determining the air-conditioning right and left angle of the enclosed air supply is taken as an example.

The opening angle of the left and right blades of the air conditioner is also the optimal left and right angle beta, and the air is sent out and returns to the air return inlet of the air conditioner through a certain air supply path. There are two cases of the left and right optimum angle β, both of which are based on the air conditioner just sending wind into the range of the cooking area, i.e., the wind of the rightmost blade just sends wind into the cooking area. The first case is: the relative position of the air conditioner in the kitchen is biased to the cooking area, and the inclination angles of the leftmost blades and the rightmost blades are consistent. The second case is: the relative position of air conditioner in the kitchen is partial to the cooking district, and the rightmost side blade inclination is less this moment, and the inclination of leftmost side blade is great. Therefore, the corresponding control program can be selected according to the actual installation position of the air conditioner, and the food area can achieve the efficient surrounding air supply effect.

And setting the optimal angle of the rightmost blade as beta 1 and the optimal angle of the leftmost blade as beta 2.

In the first case, as shown in fig. 8, assuming that the length of the whole kitchen is L, the distance from the center point of the air conditioner main body of the kitchen to the wall surface of the right cooking area is X, the height X2 from the integrated ceiling to the ground and the length of the main body is M, that is, X < L/2 (the air conditioner main body is biased toward the cooking area), the leftmost blade and the rightmost blade operate synchronously, and the optimal inclination angle β of the leftmost blade and the rightmost blade to the cooking area can be determined, that is, β 1 ═ β 2 ═ arctan (X2/((L/2-X) + M/2)).

In the second case, as shown in fig. 9, when X > L/2, and the air conditioner main body is shifted to the left (i.e., to the cooking area) with respect to the kitchen, the leftmost blade and the rightmost blade do not operate synchronously, the tilt angle of the rightmost blade is small, and the optimal angle β 1 is arctan (X2/(M/2- (X-L/2))). And the inclination angle of the leftmost blade is larger than that of the rightmost blade, the optimal inclination angle beta of the leftmost blade is selected as the inclination angle of the leftmost blade, so that the air blown out by the air conditioner can just skip over the top of the head of a person on the left table top, and the formula can be known according to a trigonometric function relation:

from the above two relations, β 2 ═ arctan (X2-X1)/(L-X-Y1) can be found.

The optimal angle acquisition method for the upper blade, the lower blade, the left blade and the right blade of the air conditioner during air supply surrounding is adopted for the space of the cooking area by the kitchen air conditioner. The principle is the same for the space of the cooking area by adopting the surrounding air supply. The value ranges of the upper and lower blade optimal angles alpha, the leftmost blade optimal angle beta 1 and the leftmost blade optimal angle beta 2 are 0-90 degrees.

As a result, as illustrated in fig. 10, the cooking area and the cooking area in the kitchen can be surrounded and blown in different areas.

As described above, by using the small-space zoned-enclosed blowing control method, the return air concentrated in the small space encloses the human body, the efficiency of the return air is optimized, and the energy loss during blowing can be reduced. In addition, the air supply mode surrounding the user makes the human body feel more comfortable, the air supply mode limited to a small range makes the system response faster, and the air supply direction, the air quantity and the temperature can be adjusted in time, so that the user can obtain comfortable body feeling in the area where the user is located.

(initial installation of kitchen air conditioner)

The kitchen air conditioner used in this embodiment is partitioned at the time of initial installation. The partition method includes the following two methods.

Firstly, according to the setting of a user, an installer respectively designates a plurality of directions pointed by air supply blades of the air conditioner through a switch on a kitchen air conditioner main body or a function menu of an external controller, and the plurality of directions correspond to areas set in a system program of the kitchen air conditioner one by one. For example, when the user faces the kitchen air conditioner main body, the left area of the user is set as a cooking area, and the right area is set as a cooking area. After obtaining the setting information, the kitchen air conditioner is stored in the memory of the main body as a fixed parameter of the daily operation mode.

Secondly, the user inputs partition information on, for example, a mobile phone APP, and the partition information is uploaded to the cloud server. The kitchen air conditioner acquires the partition information of the user area through the cloud server, and automatically completes the area division.

The partition condition adopted by the present embodiment can refer to fig. 10, and includes a cooking area and a cooking area. Wherein cooking district is provided with cooking bench, and cooking district is provided with smoke ventilator and top of a kitchen range.

The kitchen air conditioner has a configuration of software and hardware common to the bathroom air conditioner, and the setting of the operation mode as the bathroom air conditioner or the kitchen air conditioner is completed at the time of shipment, or the operation mode as the bathroom air conditioner or the kitchen air conditioner is set by an installer on site using a switch on the air conditioner main body or a function menu of an external controller.

The kitchen air conditioner is provided with an external controller. The external controller is a fixed panel or a remote control panel fixed on a wall surface or the like, and may be a touch screen Pad or an infrared remote controller, for example. The external controller is communicated with the air conditioner main body through the communication module. The external controller can start the air conditioner, select an operation mode, adjust the temperature, the air volume and the like of the air conditioner, reserve the operation of the air conditioner, control the OTA updating of programs and data in the memory, control the wireless network access setting and the like. Corresponding APP can be installed in the mobile phone to play the same control role as the external controller.

The operation mode of the kitchen air conditioner which can be selected through the external controller or the mobile phone APP comprises a cooking mode, a forced air exhaust mode, a mold removing mode and a dehumidifying mode. After the user selects the operation mode, the kitchen air conditioner is operated in the selected operation mode.

However, the operation mode of the kitchen air conditioner may be defaulted to one or both of the cooking mode and the cooking mode. When the default is the cooking mode, the front mode, the middle mode and the rear mode are three different operation modes. When the operation mode of the kitchen air conditioner includes a plurality of modes, the front mode, the middle mode and the rear mode are two-stage operation modes in the cooking mode. (newly added to correspond to claims, please confirm)

The kitchen air conditioner is also provided with a wireless switching controller. The wireless switching controller is a portable and mountable controller for switching the mode of operation or the secondary mode of operation. The wireless switching controller can communicate with the kitchen air conditioner main body. The wireless switching controller can also be communicated with an intelligent home router and an intelligent home gateway and can be accessed into a home Internet of things system.

Next, a cooking mode and a vacation mode in the partition surrounding air supply control method of the kitchen air conditioner will be described.

<1. cooking mode >

The cooking mode comprises three operation modes of a front mode, a middle mode and a rear mode. The front mode is a preparation stage from when the user does not enter the kitchen to when the user has entered the kitchen for cooking. The middle mode is a stage in which a user enters the cooking area from the cooking area to cook. The back mode is a stage in which the user enters the cooking area from the cooking area for cooking and then finishes and the user leaves the kitchen.

The front mode, the middle mode and the rear mode can be switched by operating the wireless switching controller by a user, and the front mode, the middle mode and the rear mode can also be automatically switched by detecting the condition of entering the cooking area and the cooking area or the entering sequence of the user by the human sensor. For example, after the user turns on the kitchen air conditioner through the external controller, the cooking mode is automatically entered by default and enters the "front mode", and the operation is performed according to a predetermined program. When the human detecting sensor detects that the user enters the cooking area, the mode is switched to the 'middle mode' and the operation is performed according to a predetermined program. When the human detection sensor detects that the user enters the cooking area, the mode is switched to the rear mode and the cooking area operates according to a preset program.

Moreover, the kitchen air conditioner can also acquire season parameters from the cloud server through the communication module in a wireless mode such as WiFi, Zigbee, NB-IoT and Bluetooth, and the kitchen air conditioner is further divided into an autumn and winter mode and a spring and summer mode according to different seasons.
