The technical solution shown in the present application will be described in detail by specific examples. It should be noted that the following embodiments may exist alone or in combination with each other, and description of the same or similar contents is not repeated in different embodiments.
First, an execution main body of the control method of the kitchen air conditioner provided in the embodiment of the present application may be the kitchen air conditioner, or may be an electronic device capable of controlling the kitchen air conditioner, for example, a server or a mobile terminal. The following embodiments schematically illustrate a control method of a kitchen air conditioner provided in the embodiments of the present application, taking an example in which an execution subject is the kitchen air conditioner.
Fig. 2 is a flowchart illustrating a control method of a kitchen air conditioner according to an embodiment of the present application. Referring to fig. 2, the method may include:
s201, acquiring state information of a range hood in a space where the kitchen air conditioner is located, and obtaining the ambient temperature of the kitchen air conditioner.
The space where the kitchen air conditioner is located is not limited to a home kitchen, but may be a restaurant kitchen or the like. And the state information is used for representing whether the range hood is in a working state or not. The state information can comprise a state signal of the range hood, and the state signal can start a signal to represent that the range hood is in a working state; the state signal can be a shutdown signal and represents that the range hood is in a shutdown state. The state information can also comprise an identifier of the range hood, and the identifier indicates the installation position of the range hood or the installation direction of the range hood relative to the kitchen air conditioner, so that the kitchen air conditioner can control the air outlet direction of the air outlet of the range hood according to different identifiers.
Optionally, the state information of the range hood may further include working modes of the range hood, for example, a low wind mode, a medium wind mode, and a high wind mode, and different working modes correspond to different cooling capacities of the kitchen air conditioner.
And if the state information represents that all the range hoods in the space where the kitchen air conditioner is located are not in the working state, the kitchen air conditioner is in the shutdown state. If the state information represents that the range hoods in the space where the kitchen air conditioner is located are in a working state, one range hood can be in the working state, or two or three range hoods and the like can be in the working state, the following step S202 is executed.
In the embodiment of the application, the kitchen air conditioner is in communication connection with the range hood in the space where the kitchen air conditioner is located, for example, bluetooth connection, WiFi connection and the like. After the range hood is started, the range hood sends a starting signal to a kitchen air conditioner; the kitchen air conditioner starts refrigeration after receiving the starting signal. Certainly, the kitchen air conditioner can continuously obtain the state information of the range hood, and when the state information comprises a starting signal, the representation range hood is in a working state, and refrigeration is started.
There are various ways to obtain the ambient temperature of the kitchen air conditioner. For example, an intelligent temperature sensor is installed in a kitchen and is in communication connection with a kitchen air conditioner, so that the ambient temperature of the kitchen air conditioner is obtained; for another example, the kitchen air conditioner itself may be equipped with a temperature sensor, and may be installed in an indoor unit of the kitchen air conditioner, may be installed in an outdoor unit of the kitchen air conditioner, or may be equipped with a temperature sensor in both the indoor unit and the outdoor unit of the kitchen air conditioner. Of course, the temperature sensors can be arranged in a plurality of numbers, and the temperature average value is calculated through a mathematical algorithm, so that the accuracy of temperature detection is improved.
S202, if the state information represents that the range hood in the working state exists in the space, adjusting a target parameter of the kitchen air conditioner according to the environment temperature, wherein the target parameter is related to the refrigerating capacity of the kitchen air conditioner.
The step can be understood as that when one or more range hoods are opened in the space where the kitchen air conditioner is located, the target parameters of the kitchen air conditioner are adjusted according to the environment temperature, so that the kitchen air conditioner is refrigerated, and the temperature of the space where the kitchen air conditioner is located is reduced.
The kitchen air conditioner comprises an indoor fan and an outdoor compressor, wherein the target parameters can only comprise the frequency of the compressor, the target parameters can also only comprise the rotating speed of the indoor fan, and of course, the target parameters can also comprise the frequency of the compressor and the rotating speed of the indoor fan at the same time. Generally, the frequency of the compressor is increased, so that the refrigerating capacity of the kitchen air conditioner is increased; the rotating speed of the indoor fan is increased, so that the refrigerating capacity of the kitchen air conditioner is increased.
Of course, the target parameter related to the cooling capacity of the kitchen air conditioner is not limited to the frequency of the compressor and the rotation speed of the indoor unit, and the target parameter may further include the rotation speed of the outdoor fan, etc.
Therefore, the frequency of a compressor of the kitchen air conditioner and/or the rotating speed of the indoor unit are/is adjusted according to the environment temperature, the refrigerating capacity of the kitchen air conditioner is adjusted, and the temperature of the space where the kitchen air conditioner is located is adjusted.
Fig. 3 is a scene schematic diagram of cooling of a kitchen air conditioner according to an embodiment of the present application. A cooling scenario of the kitchen air conditioner will be described with reference to fig. 3.
When a range hood in a kitchen is in a working state, a kitchen air conditioner starts a refrigeration mode to reduce the temperature in the kitchen; and adjusting the target parameters of the kitchen air conditioner according to the ambient temperature, thereby adjusting the refrigerating capacity of the kitchen air conditioner. So, according to the actual conditions in kitchen, lampblack absorber state and ambient temperature, the refrigeration capacity of adjustment kitchen air conditioner is favorable to improving accuracy and the flexibility of kitchen air conditioner control.
It should be noted that, in the kitchen air conditioner provided in the embodiments of the present application, the lowest end of the air outlet is flush with or higher than the top of the gas stove. The fan blade is installed to kitchen air conditioner's air outlet of this application embodiment, and the air-out angle of air outlet is changed through the angle of air conditioner fan blade. The air outlet angle can be horizontal, and the air outlet angle can also blow obliquely upwards, for example, blow obliquely upwards within 20 degrees of the horizontal upwards. The arrangement can prevent the air outlet from blowing downwards to the burner of the gas stove to influence the stability of the flame of the burner. And the horizontal or oblique upward air outlet can be over against the upper half of the cooker, and the temperature of the area around the cooker can be quickly reduced.
The embodiment of the application provides a control method of kitchen air conditioner, acquire the state information of the lampblack absorber in the space that kitchen air conditioner is located, and the ambient temperature that kitchen air conditioner is located, there is the lampblack absorber that is in operating condition in the state information characterization space, then according to the target parameter of ambient temperature regulation kitchen air conditioner, thereby adjust the refrigeration capacity of kitchen air conditioner, the temperature of the reduction kitchen air conditioner of different degrees, so according to the state information and the ambient temperature of the lampblack absorber of the space that kitchen air conditioner is located, the temperature in the adjustment space, be favorable to improving accuracy and the flexibility of kitchen air conditioner control.
Fig. 4 is a flowchart illustrating another kitchen air conditioner control method according to an embodiment of the present disclosure. Referring to fig. 4, the method may include:
s401, acquiring state information of a range hood in a space where the kitchen air conditioner is located, and obtaining the ambient temperature of the kitchen air conditioner.
It should be noted that the execution process of step S401 may refer to the execution process of step S201, and is not described herein again.
S402, judging whether the space has the range hood in the working state.
The step is to determine the state of a range hood in a space where a kitchen air conditioner is located, judge whether an opened range hood exists in the space, if the range hood is opened, indicate that cooking exists and the space needs to be cooled; if the range hood is not started, the cooking is not available, and the kitchen air conditioner is not required to be started.
There are various methods for judging whether the range hood in the working state exists in the space. For example, a signal switch is arranged in the range hood, the signal switch is switched on to send a signal when the range hood is started, and the signal switch is switched on to not send a signal when the range hood is closed. The kitchen air conditioner judges whether the range hood is in a working state or not by judging whether the signal is received or not. For another example, an exhaust duct of the range hood is provided with a flow sensor, and when the flow sensor detects that the gas flow in the exhaust duct exceeds a preset value, a signal is sent to the kitchen air conditioner, so that the kitchen air conditioner can judge that the range hood is in a working state. For another example, a noise sensor is installed in the range hood and used for detecting the noise of the fan in the range hood, and the kitchen air conditioner judges the working state of the range hood according to the noise value sent by the noise sensor.
When no range hood in the working state exists in the space where the kitchen air conditioner is located, namely S402 is 'No', the process is ended, and the kitchen air conditioner is in the shutdown state at the moment; if there is a range hood in an operating state in the space where the kitchen air conditioner is located, that is, if S402 is yes, the following step S403 is executed.
In an embodiment of the present application, the ambient temperature may include an outdoor ambient temperature of a space where a kitchen air conditioner is located, for example, an outdoor ambient temperature outside a kitchen. Optionally, the outdoor unit of the kitchen air conditioner is provided with a temperature sensor, so as to obtain the outdoor ambient temperature.
S403, acquiring an initial frequency of the compressor according to the outdoor environment temperature and a preset mapping relation between the outdoor environment temperature and the compressor frequency; and determining the initial rotating speed of the indoor fan according to the outdoor environment temperature.
The outdoor environment temperature affects the indoor temperature and also affects the heat dissipation of the outdoor unit evaporator, thereby affecting the refrigerating capacity of the kitchen air conditioner. The initial frequency of the compressor is determined according to the outdoor temperature, and the accuracy of kitchen air conditioner control is improved. The mapping relationship of the preset outdoor ambient temperature and the compressor frequency may be stored in a memory of the kitchen air conditioner.
For example, the mapping relationship between the preset outdoor ambient temperature and the compressor frequency may be as shown in table 1:
TABLE 1
Outdoor ambient temperature/. degree.C <22 22-32 32-40 40-48 >48
Initial frequency/Hz of compressor 35 45 70 60 40
According to the current outdoor environment temperature detected by the temperature sensor, the mapping relation between the preset outdoor environment temperature and the compressor frequency stored in the memory is inquired, so that the initial frequency of the compressor is determined, the accuracy of kitchen air conditioner control is facilitated, and the subsequent adjustment of the compressor frequency is facilitated.
It should be noted that the mapping relationship between the outdoor environment temperature and the compressor frequency may be shown in table 1, the mapping relationship between the outdoor environment temperature and the compressor frequency may also be a mathematical formula, and the initial frequency of the compressor at different outdoor environment temperatures is calculated by the mathematical formula, and the specific mathematical formula and the specific numerical values in table 1 are not limited in the embodiment of the present application.
And determining the initial rotating speed of the indoor fan according to the outdoor environment temperature. For example, a mapping relationship between the outdoor ambient temperature and the indoor fan rotation speed is stored in the memory of the kitchen air conditioner, and the mapping relationship can be shown in table 2:
TABLE 2
Outdoor ambient temperature/. degree.C <22 22-32 32-40 40-48 >48
Speed/rmp of indoor fan 750 1000 1100 1200 1300
It should be noted that the mapping relationship between the outdoor environment temperature and the indoor fan rotation speed may be as shown in table 1, the mapping relationship between the outdoor environment temperature and the indoor fan rotation speed may also be a mathematical formula, and the initial indoor fan rotation speed at different outdoor environment temperatures is calculated by the mathematical formula.
Optionally, the initial rotation speed of the indoor fan may also be obtained by receiving a control instruction. Specifically, the kitchen air conditioner receives a control command, for example, the remote controller sends a control command of a rotation speed mode to the kitchen air conditioner. Illustratively, a speed of 750rmp corresponds to a quiet mode, a speed of 1000rmp corresponds to a low wind mode, a speed of 1100rmp corresponds to a medium wind mode, a speed of 1200rmp corresponds to a high wind mode, and a speed of 1300rmp corresponds to a strong mode. And the kitchen air conditioner determines the initial rotating speed of the indoor fan according to the received control instruction.
In this application embodiment, ambient temperature can also include the indoor ambient temperature in kitchen air conditioner place space, and wherein, indoor ambient temperature does the distance is predetermine at least at interval to the temperature of uncooked area in the space, uncooked area and lampblack absorber, and this application embodiment does not restrict to predetermineeing the distance.
