Description

Control method and control device for air conditioner, air conditioner and storage medium

Technical Field

The present invention relates to the field of intelligent household electrical appliance technologies, and for example, to a control method and a control device for an air conditioner, and a storage medium.

Background

In order to maintain a comfortable indoor ambient temperature, an air conditioner has become an indispensable household electrical appliance in life. Generally, an indoor heat exchange part of an air conditioner is provided with one or more air outlets in a space, but because the blowing range of the air outlets is difficult to cover the whole space, and the trend of the up-down distribution of cold and warm air flows with different temperatures is diffused in the space, the uniform distribution effect of hot air flows or cold air flows blown out by the indoor heat exchange part in the space cannot be guaranteed. Therefore, the temperature at each location in the space cannot be uniformly adjusted along with the operation of the air conditioner, resulting in poor overall temperature adjustment effect in the space.

There is provided a control method for an air conditioner, including: detecting the ambient temperature in a plurality of areas in the space where the air conditioner is located; judging whether the distribution of the environmental temperature in the plurality of areas is uniform or not; if the environment temperature distribution of the plurality of areas is judged to be uneven, controlling the air conditioner to carry out a first energy-saving mode; wherein the first energy saving mode includes: heating parameters are increased or refrigerating parameters are increased.

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

this solution makes the temperature distribution tend to be uniform by enhancing the heating or cooling of a partial area, but in practice, the air conditioner continuously performs the operation of enhancing the heating or cooling, that is, continuously inputting heat or cold into the space, because the cool and warm air flow in the space always flows in the trend of up-down distribution. This may result in a gradual increase or decrease in the total heat in the space, which may lead to a poor user experience.

Fig. 1 is a schematic view of an application scenario of a control method for an air conditioner according to an embodiment of the present disclosure. As shown in fig. 1, the application scenario includes an air conditioner 10 and a server 11 communicating with the air conditioner. The server may be a cloud platform that communicates with the air conditioner.

Fig. 2 is a schematic diagram of a control method for an air conditioner according to an embodiment of the present disclosure, where the control method for the air conditioner may be executed in the air conditioner or may be executed in a server, such as a cloud platform in communication with the air conditioner. In the embodiment of the present disclosure, the present solution is explained with a server as an execution subject.

As shown in fig. 2, the control method for an air conditioner includes:

s201, the server obtains the temperature of a high-level space and the temperature of a low-level space in the space where the air conditioner is located.

Wherein the high-level space has a higher height than the low-level space. And the temperature of the upper space and the temperature of the lower space may be one or more.

S202, under the condition that the temperature of the high-order space is greater than the first temperature threshold value and the temperature of the low-order space is less than the second temperature threshold value, the server controls the air conditioner to operate an air supply mode.

The first temperature threshold is larger than a target temperature set by a user, and the second temperature threshold is smaller than the target temperature set by the user.

By adopting the control method for the air conditioner provided by the embodiment of the disclosure, the following technical effects can be realized: and obtaining the temperatures of a high-level space and a low-level space in the space where the air conditioner is located, and if the temperature of the high-level space is greater than a first temperature threshold value and the temperature of the low-level space is less than a second temperature threshold value, indicating that the temperature difference between the high-level space and the low-level space is too large and the heat distribution is not uniform. The air conditioner is controlled to operate in an air supply mode, so that air at different heights circulates, and heat in the space is distributed more uniformly. Meanwhile, as the input or the output of heat is not involved in the process, the total heat in the room can be ensured to be kept stable, so that the discomfort of a user caused by the whole temperature change is avoided.

Alternatively, the temperature of the elevated space may be at or near the roof. For example, 10cm, 20cm from the roof, etc. Specifically, temperature detection is performed by a temperature sensor and the temperature is transmitted to the server. Because the heat is gathered at the roof, the temperature at the roof is a higher temperature value in the space, and the judgment condition of whether to carry out the air supply mode is more accurate.

Alternatively, the temperature of the elevated space may comprise a plurality of temperatures of different heights. That is, a plurality of temperatures near the roof may be selected as the temperature of the high-level space, or the temperature at the roof and/or one or more temperatures near the roof may be selected as the temperature of the high-level space. In this way, a plurality of temperatures are used as the temperature of the high-level space, so that the adjustment is more accurate.

Further, when the temperature of the high-level space includes a plurality of temperature values, the temperature of the high-level space is greater than the first temperature threshold value. The temperature of the higher-level space being greater than the first temperature threshold value may be understood as each measured temperature value being greater than the first temperature threshold value. Therefore, the operation is ensured to be carried out under the condition that the temperature of the high-level space is overhigh, unnecessary operation can be avoided, and resources are saved. A temperature in the head space greater than the first temperature threshold may also be understood as a portion of the measured temperature values being greater than the first temperature threshold. Therefore, the operation can be ensured to be carried out under the condition of heat accumulation in time, and the heat is distributed uniformly. In addition, the average value of the plurality of measured temperature values may be used as the temperature of the head space. Thus, the error in the value of the temperature in the high-order space can be reduced.

Optionally, the temperature of the lower space comprises a temperature at one or more set elevations. And under the condition that the temperature of the low-level space is multiple, the temperature of the low-level space is smaller than the second temperature threshold value, namely all the temperatures are smaller than the second temperature threshold value.

Optionally, the determining manner of the set height includes: the server judges whether a person exists in the space where the air conditioner is located. In the case of a person, the height at which a specific body part of the person is located in the space is set as the set height.

Wherein, whether someone is in the room of the air conditioner can be detected through the infrared sensor. Whether a person is in the space of the air conditioner can be detected through the image sensor. The infrared sensor or image sensor may be provided as a separate device directly on a wall, an air conditioner, or the like in a space or at a location.

In other embodiments, it is also possible to detect whether a person is in the space where the air conditioner is located through other intelligent household electrical appliances. The intelligent household appliance is provided with an infrared sensor or an image sensor or other devices or equipment capable of detecting the personnel condition in the space. The intelligent household appliance is in communication connection with the server so as to send the personnel condition or the judgment result in the space to the server.

Optionally, the specific body part comprises one or more of an ankle, a knee, a waist, an abdomen, and a neck. Specifically, the heights of the respective body parts may be obtained by measurement in advance and stored. Thus, the actual personal requirements of the user can be better met.

The height of each body part can be measured in advance, and can also be set according to the average height in the big data. Therefore, under the condition of ensuring that the height is within a reasonable range, the actual height of a user does not need to be measured, and the operation process is simplified. Further, different height values may be determined according to the identity of the persons in the space. I.e. female corresponds to the average data for female and male corresponds to the average data for male. Thus, the height value is more accurate.

For example, temperatures at 20cm, 100cm and 150cm in height are collected as the temperature of the low-temperature space. The 20cm, 100cm and 150cm positions correspond to the ankle position, the waist and abdomen position and the neck position of the human body, respectively. And detecting the temperature at the roof and the temperatures at the three heights, and controlling the air conditioner to enter an air supply mode by the server under the condition that the three temperatures in the low-level space are all smaller than a second temperature threshold value and the temperature at the roof is greater than a first temperature threshold value.

Optionally, the determining manner of the set height further includes: in the case of no person, the center height of the space is set as the set height. Therefore, the value can accurately reflect the temperature of the low-order space, so that the adjustment is more accurate. In other embodiments, the determination of the set height may also be determining a trisection point or a quarteection point of the space as the set height. Therefore, the temperature in the low-level space can be more accurately reflected.

Optionally, a first temperature threshold

Second temperature threshold

Where T0 is the target temperature set by the user. T is the current temperature. Specifically, T is the temperature at the air inlet of the air conditioner. Therefore, the setting of the first temperature threshold and the second temperature threshold is combined with the specific actual situation, and the actual requirements of users are better met.

Optionally, the air supply mode includes: and (5) swinging the wind up and down. Therefore, heat accumulated on the roof circulates in the whole space, and heat in the space is distributed more uniformly.

Optionally, when there is a person in the space where the air conditioner is located, the method further includes: the server obtains the information of the number of the personnel. When the number of persons is large, the height of the human body part of the person with high priority is used as the set height. Wherein the priority is set by a user. For example, the user has an elderly person and an adult person in his home, and the user sets the elderly person to a first priority. Then, when the elderly person and the adult person are located in the space where the air conditioner is located at the same time, the temperature is detected with the height of each body part of the elderly person as a set height. Thus, when there are a plurality of persons in the space where the air conditioner is located, the set height can be determined by priority, and confusion is avoided. Meanwhile, the requirements of personnel with high priority can be met preferentially, and the requirements of actual life are met better.

Optionally, when there is a person in the space where the air conditioner is located, the method further includes: the server obtains the information of the number of the personnel. When the number of persons is large, the body temperatures of all the persons are detected and compared, and the height of the body part of the person with the lowest body temperature is set as the set height.

Fig. 3 is a schematic diagram of another control method for an air conditioner according to an embodiment of the present disclosure, where the control method for the air conditioner may be executed in the air conditioner or in a server, such as a cloud platform in communication with the air conditioner. In the embodiment of the present disclosure, the present solution is explained with a server as an execution subject.

As shown in fig. 3, the control method for an air conditioner includes:

s301, the server obtains the temperature of the high-level space and the temperature of the low-level space in the space where the air conditioner is located.

And S302, under the condition that the temperature of the high-level space is greater than a first temperature threshold value and the temperature of the low-level space is less than a second temperature threshold value, the server controls the air conditioner to operate in an air supply mode.

And S303, under the condition that the temperature of the high-order space and the temperature of the low-order space are both greater than the first temperature threshold value, the server controls the air conditioner to operate in a fresh air mode.

And S304, under the condition that the temperature of the high-level space and the temperature of the low-level space are both smaller than the second temperature threshold value, the server controls the air conditioner to operate in a heating mode.

By adopting the control method for the air conditioner provided by the embodiment of the disclosure, the following technical effects can be realized: and obtaining the temperatures of a high-level space and a low-level space in the space where the air conditioner is located, and if the temperature of the high-level space is greater than a first temperature threshold value and the temperature of the low-level space is less than a second temperature threshold value, indicating that the temperature difference between the high-level space and the low-level space is too large and the heat distribution is not uniform. By starting the air conditioner and operating the air supply mode, air with different heights circulates, and therefore heat in the space is distributed more uniformly. Meanwhile, as the input or the output of heat is not involved in the process, the total heat in the room can be ensured to be kept stable, so that the discomfort of a user caused by the whole temperature change is avoided. In addition, when the indoor temperature of the space where the air conditioner is located is too high or too low, the air conditioner can be automatically started and the temperature in the room can be correspondingly adjusted, so that the temperature in the space tends to the temperature range between the first temperature threshold and the second temperature threshold, and the comfort degree of a user is favorably improved.

Optionally, the fresh air mode includes an external circulation mode and an internal and external double circulation mode. Specifically, the external circulation mode introduces outdoor fresh air into the room. The inside and outside double circulation mode introduces outdoor fresh air into the room, and simultaneously, sucks indoor air into the air inlet, mixes the air with the fresh air and then sends the air out.

Optionally, in a case where the temperature of the higher space is greater than the first temperature threshold and the temperature of the lower space is less than the second temperature threshold, the method further includes: the server controls the air conditioner to blow air to the area where the preferential protection part of the personnel in the space is located. Wherein the preferential protection part is set and stored in advance by a user. For example, if the elderly at home are provided with the preferential protection position at the waist and abdomen position, the air conditioner is controlled to blow air to the waist and abdomen height of the elderly. Therefore, the temperature of the area where the preferential protection part of the personnel in the space is located can be increased as soon as possible, and the user experience is improved.

Further, if the running time of the air supply mode exceeds a first preset time length and the temperature of the height of the priority protection part is still lower than a low-level temperature threshold value, the air conditioner is controlled to run in the heating mode. The first preset time may be 10min, 20min or 30min, and the user may set the first preset time according to actual requirements. Therefore, the temperature rise speed of the area where the priority part is located can be further increased, and the user experience is optimized.

Optionally, when both the temperature of the high-order space and the temperature of the low-order space are less than the second temperature threshold, the method further includes: the server controls the air conditioner to blow air to the area where the preferential protection part of the personnel in the space is located. Wherein the preferential protection part is set and stored in advance by a user. For example, if the elderly at home are provided with the preferential protection position at the waist and abdomen position, the air conditioner is controlled to blow air to the waist and abdomen height of the elderly. Therefore, the heat quantity of the area where the preferential protection part of the personnel in the space is located can be increased in the room at a lower temperature and with a priority, and the user experience is improved.

Optionally, if it is detected that no person is in the space where the air conditioner is located and the time length of the absence of the person exceeds a second preset time length, the air conditioner is controlled to reduce the set target temperature. Wherein the second preset time period may be 30 min. Thus, the operation of the air conditioner can be more energy-saving.

Further, after controlling the air conditioner to reduce the set target temperature, if a person is detected in the air conditioner space, the server controls the air conditioner to return to the original target temperature. Therefore, manual adjustment by a user can be avoided, and user operation is simplified.

Optionally, when the space where the air conditioner is located is composed of several subspaces, the server determines the priority ranking of each subspace according to the personnel distribution situation in the space, and executes the control method for the air conditioner according to the priority ranking. For example, the space where the air conditioner is located is composed of a room a and a room B, and the room a and the room B communicate with each other. The air conditioner may operate in room a and room B. The infrared sensor or the image sensor detects the distribution of people in the space and transmits the obtained information to the server. If the user is in the room a, it is determined that the priority of the room a is higher, and therefore the air supply mode, the fresh air mode, or the heating mode is preferentially operated for the room a. Therefore, the practical requirements of users can be met more quickly, and the situation that the indoor space cannot be adjusted to the target interval for a long time due to the fact that the space where the air conditioner is located is too large is avoided.

Optionally, in a summer application scenario, the method further includes: the server calculates a difference between the temperature of the upper space and the temperature of the lower space. If the difference value is larger than the preset value, the server controls the air conditioner to adjust the angle of the air deflector and the angle of the swing blade to the position of the roof. Wherein the preset value can be 3 ℃. Therefore, hot air on the roof can be stirred, and unsmooth circulation of cold in the space caused by large accumulation of heat on the roof is avoided.

Fig. 4 is a schematic diagram of another control method for an air conditioner according to an embodiment of the present disclosure, where the control method for the air conditioner may be executed in the air conditioner or may be executed in a server, such as a cloud platform in communication with the air conditioner. In the embodiment of the present disclosure, the present solution is explained with a server as an execution subject.

As shown in fig. 4, the control method for an air conditioner includes:

s401, the server obtains the temperature of the high-level space and the temperature of the low-level space in the space where the air conditioner is located.

S402, under the condition that the temperature of the high-order space and the temperature of the low-order space are both larger than a first temperature threshold value, the server obtains the current temperature and the target temperature.

The current temperature is the temperature at the air inlet of the air conditioner. The current temperature may be measured by a temperature sensor. The temperature sensor may be located on a wall, an air conditioner, or the like, or at a location in the space. The current temperature can also be directly measured by an air conditioner or other intelligent household appliances and sent to a server.

S403, the server calculates a difference between the current temperature and the target temperature.

And S404, under the condition that the difference value is smaller than the preset threshold value, the server controls the air conditioner to operate in an external circulation mode.

And S405, controlling the air conditioner to operate in an internal and external double circulation mode by the server under the condition that the difference value is larger than a preset threshold value.

By adopting the control method for the air conditioner provided by the embodiment of the disclosure, the following technical effects can be realized: the air conditioner can be controlled to automatically start and operate a fresh air mode under the condition that the temperature of the air conditioner in the space is integrally higher, and outdoor air is introduced. Therefore, the whole temperature in the room can be reduced, indoor air circulation can be promoted, and heat distribution in the space is more uniform. Meanwhile, different actual conditions are further refined, and different operations are executed, so that the adjusting mode is more accurate and effective.

Optionally, the value range of the preset threshold is 2-5 ℃. More specifically, it may be 3 ℃. Therefore, the temperature threshold is determined in a proper range, so that the division of different conditions is more reasonable, and the adjustment of the space is more accurate.

Optionally, the external circulation mode comprises introducing fresh outdoor air into the room. Therefore, air with lower outdoor temperature can be introduced into the indoor space, so that the indoor temperature is reduced and is closer to the target temperature set by the user, and the user requirements are further met. Meanwhile, the fresh air is introduced to promote indoor heat to circulate, so that the heat distribution in the space is more uniform.

Optionally, the internal and external dual cycle mode includes introducing fresh outdoor air into the room, and simultaneously sucking indoor air into the air inlet, mixing with the fresh air, and then discharging. Therefore, the temperature in the space where the air conditioner is located can be reduced faster and is closer to the target temperature set by the user, and the user requirements are met. Meanwhile, the air in the space where the air conditioner is located is enabled to flow in an accelerated mode, and the heat distribution is more uniform.

Fig. 5 is a schematic diagram of another control method for an air conditioner according to an embodiment of the present disclosure, where the control method for the air conditioner may be executed in the air conditioner or in a server, such as a cloud platform in communication with the air conditioner. In the embodiment of the present disclosure, the present solution is explained with a server as an execution subject.

As shown in fig. 5, the control method for an air conditioner includes:

s501, the server obtains the temperature of the high-level space and the temperature of the low-level space in the space where the air conditioner is located.

And S502, under the condition that the temperature of the high-order space is greater than the first temperature threshold value and the temperature of the low-order space is less than the second temperature threshold value, the server controls the air conditioner to operate in an air supply mode.

And S503, under the condition that the temperature of the high-order space and the temperature of the low-order space are both greater than the first temperature threshold value, the server controls the air conditioner to operate in a fresh air mode.

And S504, under the condition that the temperature of the high-level space and the temperature of the low-level space are both smaller than the second temperature threshold value, the server controls the air conditioner to operate in a heating mode.

And S505, under the condition that the temperature of the high-level space and the temperature of the low-level space are both greater than or equal to a second temperature threshold and less than or equal to a first temperature threshold, the server controls the air conditioner to be closed.

By adopting the control method for the air conditioner provided by the embodiment of the disclosure, the following technical effects can be realized: and obtaining the temperatures of a high-level space and a low-level space in the space where the air conditioner is located, and if the temperature of the high-level space is greater than a first temperature threshold value and the temperature of the low-level space is less than a second temperature threshold value, indicating that the temperature difference between the high-level space and the low-level space is too large and the heat distribution is not uniform. By starting the air conditioner and operating the air supply mode, air with different heights circulates, and therefore heat in the space is distributed more uniformly. Meanwhile, as the input or the output of heat is not involved in the process, the total heat in the room can be ensured to be kept stable, so that the discomfort of a user caused by the whole temperature change is avoided. In addition, when the temperature of the high-level space and the temperature of the low-level space in the space of the air conditioner return to the range between the first temperature threshold and the second temperature threshold, the air conditioner can be controlled to be automatically turned off, manual setting by a user is not needed, and operation of the user is simplified. Meanwhile, the air conditioner is turned off in time, and the resource is saved.
