Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of smart home devices, for example to a control method and device for an air conditioner in a kitchen and a smart air conditioner. BACKGROUND

[0002] Generally, the control process of an air conditioner takes the comfort of a user as a control target. The environment in a kitchen is relatively complex, and the temperature requirements are quite different. For example, during cooking, hot dishes are usually placed on the kitchen counter; during cooking, some cold dishes are also placed on the kitchen counter; in this environment, if the comfort of the person is taken as the control target of the air conditioner, the hot dishes will encounter air outlet after being taken out of the pot, and the cooling speed will be relatively fast, which is easy to reduce the taste.

[0003] To this end, the space in the kitchen can be divided into a hot dish area and a human activity area, and based on the hot dish area and the human activity area, the angle of the air deflector of the air conditioner is adjusted to avoid the air outlet of the air conditioner directly blowing on the hot dish area, so as to reduce the adverse effects of the kitchen air conditioner on the hot dishes while ensuring the comfort of the person.

[0004] In the process of implementing the embodiments of the present application, it is found that at least the following problems exist in the related art:

[0005] In the actual cooking process, the user will also make some cold dishes, and the cold dishes will also be placed on the kitchen counter. The temperature required by the cold dishes is usually lower than the temperature required by the comfort of the person. In the process of controlling the air conditioner with the comfort of the user as the control target, the air outlet temperature of the air conditioner will be higher than the temperature required by the cold dishes, and the direct blowing of the air conditioner on the cold dishes will reduce the taste, appearance and the like of the cold dishes. Even if the processing method similar to that for the hot dish area is adopted, that is, the air outlet of the air conditioner does not directly blow on the cold dishes, due to the relatively high overall temperature in the kitchen, the taste, appearance and the like of the cold dishes will also be reduced.

[0037] Figure 1 is a schematic diagram of an environment in a kitchen provided by an embodiment of the present application, to exemplarily illustrate the implementation environment of the control method of the air conditioner in the kitchen.

[0038] As shown in Figure 1 , the environment in the kitchen is divided into three preset temperature demand areas, which are: a low temperature demand area A1, a high temperature demand area A2, and a comfortable temperature demand area A3.

[0039] The low temperature demand area A1 can be used to place cold dishes, and of course, the low temperature demand area A1 can also include the setting area of the sink 11.

[0040] The high temperature demand area A2 can be used to place hot dishes, and of course, the high temperature demand area A2 can also include the setting area of the cooking bench 12.

[0041] The comfortable temperature demand area A3 is the activity area of the user, such as the passageway in the kitchen, the standing area of personnel around the sink, and the standing area of personnel around the cooking bench.

[0042] During the cooking process, the user can place the served dishes in the low temperature demand area A1 or the high temperature demand area A3, and the infrared imaging technology detector can be used to detect the dish outline.

[0043] In the embodiments of the present application, the dish outline detected by the infrared imaging device adjusts the current air outlet temperature and / or the current air outlet speed of the air conditioner in the low temperature demand area, to adjust the cold quantity delivered to the low temperature demand area, and further adjust the temperature of the low temperature demand area, so as to provide a temperature for the dishes in the low temperature demand area that is conducive to prolonging the taste retention time and the visual retention time.

[0044] Figure 2 is a flowchart of a control method of an air conditioner in a kitchen provided by an embodiment of the present application. The control method of the air conditioner in the kitchen can be executed by a controller of the air conditioner.

[0045] In combination Figure 2 , the control method of the air conditioner in the kitchen comprises:

[0046] S201, obtaining dish outline information of a preset temperature demand area of a kitchen.

[0047] The preset temperature demand area in the embodiments of the present application refers to a region divided in space. The preset temperature demand area can include a low-temperature demand area, a high-temperature demand area and a comfortable temperature demand area. The low-temperature demand area corresponds to part of the kitchen countertop, and the low-temperature demand area can include the setting area of the sink. The high-temperature demand area corresponds to part of the kitchen countertop, and the high-temperature demand area can include the setting area of the cooking range. The comfortable temperature demand area corresponds to the activity area of the person in the kitchen.

[0048] The vessel contour information can be obtained by infrared imaging technology.

[0049] Further, the preset temperature demand area can be divided in the following manner: obtaining the spatial layout of the kitchen, the spatial layout including the area where the cooking range is located, the area where the sink is located and the activity area of the person; determining the area where the cooking range is located and the area around the area where the cooking range is located as the high-temperature demand area; determining the area where the sink is located and the area around the area where the sink is located as the low-temperature demand area; and determining the activity area of the person as the comfortable temperature demand area. In this way, the preset temperature demand area can be obtained.

[0050] In some specific applications, the related data of the preset temperature demand area is stored in a database. In the process of executing the control method of the kitchen air conditioner provided in the embodiments of the present application, the related data can be obtained by reading the related data in the database.

[0051] The aforementioned spatial layout information can be manually set by the user, and the data set by the user is read by the controller and stored in the database. Alternatively, the aforementioned spatial layout information can be automatically set by the controller. For example, an image reflecting the spatial layout of the image can be obtained, and the cooking range, the sink and the non-kitchen countertop area (the activity area of the person) in the image can be identified by image recognition technology. The image is then divided into a plurality of sub-areas by gridding. In this way, the area where the cooking range is located can include one or more sub-areas, and the area where the sink is located can include one or more sub-areas. The sub-area where the cooking range is located and one or more sub-areas around the sub-area where the cooking range is located are determined as the high-temperature demand area. The sub-area where the sink is located and one or more sub-areas around the sub-area where the sink is located are determined as the low-temperature demand area. The non-kitchen countertop area is determined as the comfortable temperature demand area.

[0052] Of course, the specific ways of obtaining the preset temperature demand area provided above are only exemplary, and in specific applications, those skilled in the art can also obtain the aforementioned preset temperature demand area by other existing technologies that conform to the actual application scenarios.

[0053] S202, in the case that a new vessel contour appears in the low-temperature demand area in the preset temperature demand area, determining a new set temperature corresponding to the new vessel contour according to the correspondence between the vessel contour and the set temperature.

[0054] The new-ware profile appearing in the low-temperature demand area includes two scenarios: in the first scenario, no ware profile exists in the low-temperature demand area in the previous detection process, and a new ware profile appears in the low-temperature demand area in the current detection process; in the second scenario, a ware profile exists in the low-temperature demand area in the previous detection process, and a new ware profile additionally appears in the low-temperature demand area in the current detection process.

[0055] The correspondence between the ware profile and the set temperature reflects the cooking habit of the user, for example, the user is used to placing cold dishes in a plate, or the user is used to placing cold dishes in a dish. The correspondence between the ware profile and the set temperature can be manually input by the user according to the cooking habit of the user. The correspondence between the ware profile and the set temperature can be stored in a database. In the case where a new ware profile appears in the low-temperature demand area, the new set temperature corresponding to the new ware profile can be obtained by searching the new ware profile in the database.

[0056] Specifically, determining the new set temperature corresponding to the new ware profile according to the correspondence between the ware profile and the set temperature can include: determining the current ware code corresponding to the new ware profile according to the correspondence between the ware profile and the code; and determining the new set temperature corresponding to the current ware code according to the correspondence between the code and the temperature.

[0057] The correspondence between the ware profile and the code can be automatically generated by the infrared imaging device, for example, after the infrared imaging device detects a ware profile, a unique code is automatically set for the ware profile.

[0058] The correspondence between the code and the temperature can be manually input by the user according to the cooking habit of the user.

[0059] S203, in the case where the air outlet direction of the air conditioner points to the low-temperature demand area, a new current temperature inside the new ware profile is obtained.

[0060] The air outlet direction of the air conditioner is adjusted by the angle of the air deflector. In the embodiments of the present application, the preset temperature area in the kitchen is a fixed area, and the installation position of the air conditioner is fixed, that is, the relative position of the air conditioner relative to the preset temperature area in the kitchen is fixed. Therefore, when the air deflector of the air conditioner is in a first angle range, the air outlet direction of the air conditioner points to the high-temperature demand area; when the air deflector of the air conditioner is in a second angle range, the air outlet direction of the air conditioner points to the low-temperature demand area; and when the air deflector of the air conditioner is in a third angle range, the air outlet direction of the air conditioner points to the comfortable temperature demand area.

[0061] The correspondence between the angle range and the preset temperature demand area can be stored in a database. By detecting the current angle of the air deflector of the air conditioner and searching the current angle in the database, the preset temperature demand area pointed to by the air outlet direction of the air conditioner can be determined.

[0062] The new current temperature inside the new dish contour refers to the current temperature of the cold dish placed in the new dish. The new current temperature inside the new dish contour can be obtained by infrared imaging technology.

[0063] S204, controlling the current air outlet temperature and / or the current air outlet speed of the air conditioner according to the new current temperature and the updated set temperature.

[0064] The updated set temperature has a positive correlation with the new set temperature. That is, before this step, there is also a step of updating the original set temperature according to the new set temperature.

[0065] For example, in the previous detection process, no dish contour is detected in the low-temperature demand area, and in the current detection process, a new dish contour is detected in the low-temperature demand area. The new set temperature can directly replace the original set temperature to obtain the updated set temperature; or in the previous detection process, a dish contour is detected in the low-temperature demand area, and in the current detection process, an additional new dish contour is detected in the low-temperature demand area. The original set temperature can be fine-tuned according to the new set temperature, and the fine-tuned set temperature is determined as the updated set temperature. Further, if the new set temperature is greater than the original set temperature, the original set temperature is increased, and the increased set temperature is determined as the updated set temperature; if the new set temperature is less than the original set temperature, the original set temperature is decreased, and the decreased set temperature is determined as the updated set temperature.

[0066] The current air outlet temperature and / or the current air outlet speed of the air conditioner affect the amount of cold delivered by the air conditioner to the low-temperature demand area.

[0067] In some application scenarios, the existing control method with deviation elimination function can be used to control the current air outlet temperature and / or the current air outlet speed of the air conditioner according to the new current temperature and the updated set temperature to eliminate the temperature deviation between the new current temperature and the updated set temperature. Such control methods with deviation elimination function include but are not limited to proportional-integral-differential (PID) control method.

[0068] The appearance of a new dish contour in a low-temperature demand area in a preset temperature demand area indicates that a cold dish is placed in the low-temperature demand area. In this case, the new set temperature is determined according to the new dish contour, and the updated set temperature is obtained. According to the new current temperature inside the new dish contour and the new set temperature, the current air outlet temperature and / or the current air outlet speed of the air conditioner to the low-temperature demand area is adjusted to provide cold for the cold dish placed in the new dish to prolong the taste retention time and the visual retention time, thereby prolonging the taste retention time and the visual retention time of the cold dish.

[0069] The following will be exemplarily described in combination with three preset temperature demand areas in the kitchen: a high temperature demand area, a low temperature demand area and a comfortable temperature demand area.

[0070] The current air outlet temperature and / or the current air outlet speed of the air conditioner are controlled according to the new current temperature and the updated set temperature, including the following three cases: in a first case, the current air outlet temperature of the air conditioner is controlled according to the new current temperature and the updated set temperature; in a second case, the current air outlet speed of the air conditioner is controlled according to the new current temperature and the updated set temperature; and in a third case, the current air outlet temperature and the current air outlet speed of the air conditioner are controlled according to the new current temperature and the updated set temperature.

[0071] The current air outlet speed of the air conditioner is controlled according to the new current temperature and the updated set temperature, which can include:

[0072] A current first distance between the new dish contour and a first boundary is obtained; the first boundary is a boundary between the low temperature demand area and the high temperature demand area in the preset temperature demand area; in a case where the new current temperature is higher than the updated set temperature, a current temperature difference between the new current temperature and the updated set temperature is obtained; according to a corresponding relationship among the temperature difference, the first distance and the air outlet speed, a current air outlet speed corresponding to the current temperature difference and the current first distance is determined, wherein the air outlet speed is positively correlated with the temperature difference and the air outlet speed is positively correlated with the first distance.

[0073] In a case where the new current temperature is higher than the updated set temperature, it indicates that the low temperature demand area needs to be cooled at this time, the greater the temperature difference, the faster the air outlet speed, which is beneficial to quickly reduce the temperature of the low temperature demand area; the smaller the first distance, the slower the air outlet speed, which is beneficial to reduce the influence of the low temperature on dishes in the high temperature demand area, especially in a case where the high temperature demand area includes a region where a cooking stove is arranged, the smaller the first distance, the slower the air outlet speed, which is beneficial to reduce the adverse effect of the air speed on the efficiency of the cooking stove, and further to maintain the heating efficiency of the cooking stove.

[0074] The current air outlet temperature of the air conditioner is controlled according to the new current temperature and the updated set temperature, which can include: a current second distance between the new dish contour and a second boundary is obtained; the second boundary is a boundary between the low temperature demand area and the comfortable temperature demand area in the preset temperature demand area; in a case where the new current temperature is higher than the updated set temperature, a current temperature difference between the new current temperature and the updated set temperature is obtained; according to a corresponding relationship among the temperature difference, the second distance and the air outlet temperature, a current air outlet temperature corresponding to the current temperature difference and the current second distance is determined, wherein the air outlet temperature is negatively correlated with the temperature difference and the air outlet temperature is negatively correlated with the second distance.

[0075] In the case that the new current temperature is higher than the updated set temperature, it indicates that the low-temperature demand area needs to be cooled at this time. In this case, the greater the temperature difference, the lower the outlet air temperature, which is conducive to quickly reducing the temperature of the low-temperature demand area. The smaller the second distance, the higher the outlet air temperature, which is conducive to reducing the discomfort caused by cold air to the user and improving the comfort of the user.

[0076] The method for controlling the current outlet air temperature and the current outlet air speed of the air conditioner according to the new current temperature and the updated set temperature can include: obtaining a current first distance of the new vessel profile from a first boundary and a current second distance from a second boundary; the first boundary is a boundary between the low-temperature demand area and a high-temperature demand area in the preset temperature demand area, and the second boundary is a boundary between the low-temperature demand area and a comfortable temperature demand area in the preset temperature demand area; in the case that the new current temperature is higher than the updated set temperature, obtaining a current temperature difference between the new current temperature and the updated set temperature; determining a current outlet air speed corresponding to the current temperature difference and the current first distance according to a corresponding relationship among the temperature difference, the first distance, and the outlet air speed, wherein the outlet air speed is positively correlated with the temperature difference, and the outlet air speed is positively correlated with the first distance; determining a current outlet air temperature corresponding to the current temperature difference and the current second distance according to a corresponding relationship among the temperature difference, the second distance, and the outlet air temperature, wherein the outlet air temperature is negatively correlated with the temperature difference, and the outlet air temperature is negatively correlated with the second distance.

[0077] In combination Figure 3 As shown in the actual application scenario, the high-temperature demand area A2 and the low-temperature demand area A1 on the kitchen countertop are usually arranged adjacent to each other, and the high-temperature demand area A2 and the low-temperature demand area A1 are both adjacent to the comfortable temperature demand area A3. In this case, the first boundary B1 between the low-temperature demand area A1 and the high-temperature demand area A2 and the second boundary B2 between the low-temperature demand area A1 and the comfortable temperature demand area A3 intersect. In the process of transporting cold energy to the low-temperature demand area A1, the outlet air speed is adjusted based on the first boundary B1, and the outlet air temperature is adjusted based on the second boundary B2, so that the air supply temperature and / or the air supply speed at each position of the low-temperature demand area A1 can simultaneously reduce the adverse effects on the high-temperature demand area A2 and the comfortable temperature demand area A3.

[0078] The following exemplary describes the specific steps of determining the current outlet air speed and / or the current outlet air temperature.

[0079] The corresponding relationship among the temperature difference, the first distance, and the outlet air speed, and the corresponding relationship among the temperature difference, the second distance, and the outlet air temperature can be pre-stored in a database. After obtaining the current temperature difference, the current first distance, and the current second distance, the current outlet air speed corresponding to the current temperature difference and the current first distance and the current outlet air temperature corresponding to the current temperature difference and the current second distance can be obtained by querying the database.

[0080] Further, determining the current air outlet speed corresponding to the current temperature difference and the current first distance according to the correspondence between the temperature difference, the first distance and the air outlet speed can include: determining an initial air outlet speed corresponding to the current temperature difference according to the correspondence between the temperature difference and the air outlet speed; determining a basic air outlet speed according to the initial air outlet speed, so that the adverse effect of the air speed at the first boundary caused by the basic air outlet speed on the high temperature demand area in the preset temperature demand area meets the expectation; determining the correspondence between the distance and the air speed according to the basic air outlet speed and the preset first distance; and determining the current air outlet speed corresponding to the current first distance according to the correspondence between the distance and the air speed.

[0081] The temperature difference and the air speed are in a positive correlation, that is, the greater the temperature difference, the greater the air speed; the smaller the temperature difference, the smaller the air speed.

[0082] The adverse effect of the air speed at the first boundary caused by the basic air outlet speed on the high temperature demand area in the preset temperature demand area meets the expectation, including that the cooling effect of the air speed at the first boundary on the high temperature demand area meets the expectation, and the adverse effect of the air speed at the first boundary on the heating efficiency of the stove in the high temperature demand area meets the expectation.

[0083] For example, if the air speed at the first boundary is less than or equal to the air speed threshold, it is determined that the adverse effect of the air speed at the first boundary caused by the basic air outlet speed on the high temperature demand area in the preset temperature demand area meets the expectation. The air speed at the first boundary is less than or equal to the air speed threshold, so that the cold quantity of the air flowing to the high temperature demand area is small, and the cooling effect on the high temperature demand area is small; the air speed at the first boundary is less than or equal to the minimum air speed threshold, so that the air speed at the stove in the high temperature demand area is lower, and the adverse effect on the heating efficiency of the stove is lower.

[0084] In some specific application scenarios, the minimum air speed threshold can be 0.2 m / s or 0.3 m / s. The standard of the heating efficiency of the stove is greater than or equal to 55%, and when the air speed at the stove is zero, the heating efficiency of the stove is usually greater than 55%, for example, 58% to 60%; the greater the air speed at the stove, the lower the heating efficiency of the stove. Experiments show that when the air speed at the stove is 0.2 m / s, the heating efficiency of the stove can be 55%. Therefore, the minimum air speed threshold can be determined as 0.2 m / s or 0.3 m / s to ensure that the heating efficiency of the stove meets the relevant standards.

[0085] The above determining the basic air outlet speed according to the initial air outlet speed can include: in a case where the initial air outlet speed is less than or equal to the maximum air speed corresponding to the preset first distance, determining the initial air outlet speed as the basic air outlet speed; and in a case where the initial air outlet speed is greater than the maximum air speed corresponding to the preset first distance, determining the maximum air speed as the basic air outlet speed.

[0086] The wind speed at the first boundary refers to the wind speed at the first boundary under the influence of the air outlet speed of the air conditioner.

[0087] In the positive correlation between the air outlet speed and the first distance, if the wind speed at the first boundary is the wind speed threshold, the wind speed at the preset first distance is the maximum wind speed.

[0088] The above technical solution limits the upper limit of the air outlet speed, so that the wind speed at the first boundary is less than or equal to the wind speed threshold, and the adverse effect of the wind speed at the first boundary caused by the basic air outlet speed on the high temperature demand area in the preset temperature demand area is in line with expectations.

[0089] The aforementioned corresponding relationship between the distance and the wind speed determined according to the basic air outlet speed and the preset first distance has a corresponding relationship with the basic air outlet speed and the first preset distance.

[0090] Specifically, the positive correlation between the air outlet speed and the first distance includes a plurality of corresponding relationships between the wind speed and the distance. In the case of obtaining the basic air outlet speed and the preset first distance, the corresponding relationship between the wind speed and the distance corresponding to the basic air outlet speed and the preset first distance can be determined from the plurality of corresponding relationships between the wind speed and the distance.

[0091] The plurality of corresponding relationships between the wind speed and the distance can be obtained by experiments and stored in a database. In specific applications, the layout of the kitchen is different, and the resistance to wind speed is also different. For each kitchen, a plurality of corresponding relationships between the wind speed and the distance can be obtained by multiple experiments.

[0092] Optionally, determining the current air outlet temperature corresponding to the current temperature difference and the current second distance according to the corresponding relationship between the temperature difference, the second distance and the air outlet temperature includes: determining the initial air outlet temperature corresponding to the current temperature difference according to the corresponding relationship between the temperature difference and the temperature; determining the basic air outlet temperature according to the initial air outlet temperature, so that the adverse effect of the temperature at the second boundary caused by the basic air outlet temperature on the comfortable temperature demand area in the preset temperature demand area is in line with expectations; determining the corresponding relationship between the distance and the temperature according to the basic air outlet temperature and the preset second distance; determining the current air outlet temperature corresponding to the current second distance according to the corresponding relationship between the distance and the temperature.

[0093] The temperature difference and the temperature are negatively correlated, that is, the greater the temperature difference, the lower the air outlet temperature; the smaller the temperature difference, the higher the air outlet temperature.

[0094] The adverse effect of the temperature at the second boundary caused by the basic outlet air temperature on the comfortable temperature demand area in the preset temperature demand area is as expected, which refers to the difference between the temperature at the second boundary and the comfortable temperature of the comfortable temperature demand area being within a temperature threshold range. The temperature at the second boundary can be higher than the comfortable temperature of the comfortable temperature demand area, which is beneficial to energy saving (in the current cooling scenario, the higher the temperature, the more beneficial to energy saving); the temperature at the second boundary can be lower than the comfortable temperature of the comfortable temperature demand area, which is beneficial to maintaining the taste and appearance of cold dishes in the low-temperature demand area. As a reference, the smaller the area of the low-temperature demand area, the lower the temperature at the second boundary than the comfortable temperature of the comfortable temperature demand area; the larger the area of the low-temperature demand area, the higher the temperature at the second boundary than the comfortable temperature of the comfortable temperature demand area.

[0095] The temperature threshold can be 1-2℃.

[0096] The determination of the basic outlet air temperature according to the initial outlet air temperature can include: in the case that the initial outlet air temperature is greater than or equal to the minimum temperature corresponding to the preset second distance, determining the initial outlet air temperature as the basic outlet air temperature; in the case that the initial outlet air temperature is less than the minimum temperature corresponding to the preset second distance, determining the minimum temperature as the basic outlet air temperature.

[0097] The temperature at the second boundary refers to the temperature at the second boundary under the influence of the outlet air temperature and the outlet air speed of the air conditioner; and the minimum temperature corresponding to the preset second distance refers to the temperature at the preset second distance under the influence of the outlet air temperature and the outlet air speed of the air conditioner.

[0098] In the negative correlation between the outlet air temperature and the second distance, if the temperature at the second boundary takes the minimum value, the temperature at the preset second distance is the minimum temperature.

[0099] The above technical solution limits the lower limit of the outlet air temperature, so as to make the difference between the temperature at the second boundary and the comfortable temperature of the comfortable temperature demand area within a temperature threshold range, and further make the adverse effect of the temperature at the second boundary caused by the basic outlet air temperature on the comfortable temperature demand area in the preset temperature demand area as expected.

[0100] The inverse correlation between the outlet air temperature and the second distance includes a plurality of corresponding relationships between distance and temperature, and in the case that the basic outlet air temperature and the preset second distance are obtained, the corresponding relationship between distance and temperature corresponding to the basic outlet air temperature and the preset second distance can be determined from the plurality of corresponding relationships between distance and temperature.

[0101] The correspondence between the distance and the temperature can be obtained through experiments and stored in a database. In a specific application, the layout of the air outlet is different, and the influence of the air temperature distribution is also different. For each kitchen, a plurality of corresponding relationships between the distance and the temperature can be obtained through multiple experiments.

[0105] For example, the current air outlet speed can be set to zero.

[0107] S404, if the air outlet direction of the air conditioner points to the low temperature demand area in the case where there is no utensil contour in the low temperature demand area, control the air conditioner according to the human comfortable temperature corresponding to the comfortable temperature demand area.
