Description

Technical Field

[0001] The present invention belongs to the technical field of air conditioners, and specifically provides an air conditioner and a power-saving control method for refrigeration thereof. Background Art

[0002] An air conditioner is a device that can cool an environment and provide a cool and comfortable environment for users on hot summer days. However, existing air conditioners consume a lot of power when cooling the environment.

[0003] Existing air conditioners can cool the environment when operating in cooling mode and dehumidification mode. Compared with cooling mode, air conditioners consume less energy when operating in dehumidification mode. Moreover, compared with cooling mode, the cooling temperature of air conditioners in dehumidification mode can be reduced by about 2°C to 4°C.

[0004] Therefore, how to enable the air conditioner to provide a comfortable environment for users through the dehumidification mode has become a technical problem that needs to be solved urgently in this field. Summary of the invention

[0005] An object of the present invention is to solve at least one of the above technical problems.

[0006] A further object of the present invention is to further save energy consumption during the air conditioning dehumidification process.

[0007] To achieve the above object, the present invention provides, in a first aspect, a power saving control method for air conditioning refrigeration, comprising:

[0008] In response to the air conditioner being turned on, obtaining the current ambient humidity H1;

[0009] Determine whether the current ambient humidity H1 is greater than a humidity threshold;

[0010] If it is greater, the air conditioner is controlled to operate in a dehumidification mode.

[0011] Optionally, while obtaining the current ambient humidity H1, the power saving control method further includes: obtaining the current ambient temperature and recording it as the initial ambient temperature M1;

[0012] While executing the step of controlling the air conditioner to operate in the dehumidification mode, the power saving control method further includes:

[0013] Obtain the current ambient temperature in real time and record it as the real-time ambient temperature M2;

[0014] Determine whether the difference between the initial ambient temperature M1 and the real-time ambient temperature M2 is less than or equal to a temperature threshold;

[0015] If it is less than or equal to, the air conditioner is controlled to switch from the dehumidification mode to the cooling mode.

[0016] Optionally, after the step of controlling the air conditioner to switch from the dehumidification mode to the cooling mode, the power saving control method includes:

[0017] Determine whether the current ambient humidity H1 is less than or equal to the user's suitable humidity H0;

[0018] If it is less than or equal to, the air conditioner is controlled to start the humidification function.

[0019] Optionally, after the step of determining whether the current ambient humidity H1 is less than or equal to a humidity threshold, the power saving control method further includes:

[0020] If it is less than or equal to, the air conditioner is controlled to operate in cooling mode, and / or the air conditioner is controlled to turn on the humidification function.

[0021] Optionally, the power saving control method further includes:

[0022] In response to the air conditioner operating in the dehumidification mode for a preset time period, the air conditioner is controlled to start a vibration function so that fins of an evaporator of the air conditioner vibrate.

[0023] Optionally, the step of controlling the air conditioner to start a vibration function includes:

[0024] Determining a vibration frequency of a vibrator of the air conditioner according to the current ambient humidity H1, wherein the vibrator is used to drive the fins to vibrate;

[0025] The vibrator is controlled to operate according to the determined vibration frequency.

[0026] Optionally, the step of determining the vibration frequency of the vibrator of the air conditioner according to the current ambient humidity H1 includes:

[0027] f=H1×d

[0028] Wherein, d is the frequency base and is selected from any value between 50 Hz and 1000 Hz.

[0029] Optionally, the step of determining the vibration frequency of the vibrator of the air conditioner according to the current ambient humidity H1 includes:

[0030] The vibration frequency corresponding to the current ambient humidity H1 is found from a pre-stored current ambient humidity-vibration frequency mapping table, and the found vibration frequency is determined as the vibration frequency of the vibrator.

[0031] Optionally, the step of determining the vibration frequency of the vibrator of the air conditioner according to the current ambient humidity H1 further includes:

[0032] Obtaining the vibration noise of the air conditioner;

[0033] Determining whether the vibration noise is greater than or equal to a preset noise threshold;

[0034] If yes, increase or decrease the vibration frequency of the vibrator until the vibration noise is less than the noise threshold.

[0035] In a second aspect, the present invention provides an air conditioner, comprising a processor and a memory, wherein a machine executable program is stored in the memory, and when the processor executes the machine executable program, the power saving control method described in any one of the first aspects can be implemented.

[0036] Based on the foregoing description, those skilled in the art can understand that, in the aforementioned technical solution of the present invention, when the air conditioner is turned on, by obtaining the current ambient humidity H1 and judging whether the current ambient humidity H1 is greater than the humidity threshold, the air conditioner is controlled to operate in the dehumidification mode when it is greater than the humidity threshold. Compared with directly operating the cooling mode when the air conditioner is turned on, the present invention effectively reduces the energy consumption of the air conditioner. Those skilled in the art can also understand that, since the present invention is a dehumidification mode that is only operated when the current ambient humidity H1 is greater than the humidity threshold, it also effectively avoids the indoor air from being too dry, affecting the comfort of the user.

[0037] Furthermore, when the air conditioner is turned on, the current ambient temperature is obtained and recorded as the initial ambient temperature M1; then, when the air conditioner is in dehumidification mode, the current ambient temperature is obtained in real time and recorded as the real-time ambient temperature M2, and it is determined whether the difference between the initial ambient temperature M1 and the real-time ambient temperature M2 is less than or equal to the temperature threshold. If it is less than or equal to, it means that the air conditioner has reached the cooling limit in the dehumidification mode, and the air conditioner is controlled to switch from the dehumidification mode to the cooling mode, so that the air conditioner can continue to cool the environment.

[0038] Furthermore, when the air conditioner has been running in the dehumidification mode for a preset period of time, a certain amount of condensed water has formed on the evaporator of the air conditioner. At this time, by controlling the air conditioner to turn on the vibration function, the fins of the evaporator can vibrate, promoting the flow of condensed water on the fins, preventing the condensed water from being retained on the surface of the fins due to its own viscosity and tension, thereby preventing the condensed water from absorbing too much cold from the evaporator. At the same time, the vibrating fins can also loosen foreign matter (such as dust, lint, dust, etc.) adhering to the fins and flow down with the condensed water, preventing the evaporator of the air conditioner from breeding bacteria after long-term use.

[0039] Furthermore, during the vibration of the fins, the vibration noise of the air conditioner is obtained, and it is determined whether the vibration noise is greater than or equal to a preset noise threshold. If the result is yes, the vibration frequency of the vibrator is increased or decreased until the vibration noise is less than the noise threshold. Therefore, the present invention also ensures that the vibration of the fins will not affect the user's life and ensures the user's experience of the air conditioner.

[0040] Other beneficial effects of the present invention will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand the improved purposes, features and advantages of the present invention.

[0051] It should be understood by those skilled in the art that the embodiments described below are only some embodiments of the present invention, rather than all embodiments of the present invention, and these embodiments are intended to explain the technical principles of the present invention, rather than to limit the protection scope of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should still fall within the protection scope of the present invention.

[0052] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "top", "bottom", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0053] Furthermore, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] In addition, it should be noted that in the description of the present invention, the terms "cold" and "heat" are two descriptions of the same physical state. That is, the higher the "cold" of a certain target object (such as an evaporator, air, condenser, etc.), the lower the "heat" it has, and the lower the "cold" it has, the higher the "heat" it has. A certain target object will release "heat" while absorbing "cold", and will absorb "heat" while releasing "cold".

Those skilled in the art should understand that, under the premise of being able to implement the technical solution described in the present invention, no matter how the composition, implementation and positional relationship of each functional module change, they will not deviate from the technical principle of the present invention, and therefore should fall within the protection scope of the present invention.

[0056] like Figure 1 As shown, the air conditioner 100 (specifically, its indoor unit) includes an evaporator 110 and a fan 120. The evaporator 110 is used to cool the air entering the air conditioner 100, and the fan 120 is used to drive the air to circulate inside and outside the air conditioner 100, thereby achieving cooling of the room where the air conditioner 100 is located.

[0057] The air conditioner and the power saving control method for refrigeration thereof in the present invention will be described in detail below with reference to the accompanying drawings and in combination with specific embodiments.

[0058] like Figure 2 As shown, in the first embodiment of the present invention, the power saving control method for air conditioning refrigeration includes:

[0059] Step S110, in response to the air conditioner 100 being turned on, obtaining the current ambient humidity H1.

[0060] Specifically, when the air conditioner 100 is turned on, the current ambient humidity H1 of the room where the air conditioner 100 (specifically, the indoor unit thereof) is located can be detected by a humidity sensor disposed on the indoor unit of the air conditioner 100 .

[0061] Step S120, determining whether the current ambient humidity H1 is greater than a humidity threshold.

[0062] Among them, the humidity threshold is 30%.

[0063] In addition, those skilled in the art may also set the humidity threshold to any other feasible value as needed. For example, when the air conditioner 100 detects that the indoor user is an elderly person, the humidity threshold is set to 40%.

[0064] Step S130: if it is greater than, control the air conditioner 100 to operate in the dehumidification mode.

[0065] Those skilled in the art can understand that if the current ambient humidity H1 is greater than the humidity threshold, it means that the current indoor air humidity is acceptable and at least will not cause discomfort to the user.

[0066] Optional step S140, if less than or equal to, control the air conditioner 100 to operate in cooling mode, and / or control the air conditioner 100 to turn on the humidification function.

[0067] Those skilled in the art can understand that if the current ambient humidity H1 is less than or equal to the humidity threshold, it means that the indoor air humidity is low and the user's body begins to feel uncomfortable, for example, the user begins to experience dry nose, dry eyes, thirst, dry skin, etc.

[0068] At this time, only the humidification function of the air conditioner 100 can be turned on; or only the air conditioner 100 can be controlled to operate in the cooling mode; and the humidification function of the air conditioner 100 can be turned on when the air conditioner 100 is controlled to operate in the cooling mode; so as to prevent the air conditioner 100 from continuing to dehumidify the room, thereby preventing the indoor air from becoming too dry.

[0069] In the present invention, the indoor unit of the air conditioner 100 is equipped with a humidification module, and the water source used by the humidification module to humidify the air can be water added by the user or water generated during the cooling process of the air conditioner 100.

[0070] Based on the foregoing description, it can be understood by those skilled in the art that, in the first embodiment of the present invention, when the air conditioner 100 is turned on, the current ambient humidity H1 is obtained, and it is determined whether the current ambient humidity H1 is greater than the humidity threshold, so that when it is greater than the humidity threshold, the air conditioner 100 is controlled to operate in the dehumidification mode. Compared with directly operating the cooling mode when the air conditioner 100 is turned on, the energy consumption of the air conditioner 100 is effectively reduced. It can also be understood by those skilled in the art that, since the first embodiment of the present invention is a dehumidification mode that is operated only when the current ambient humidity H1 is greater than the humidity threshold, it also effectively avoids the indoor air from being too dry, which affects the comfort of the user.

[0071] It should be noted that the above-mentioned embodiment of the present invention is only a basic embodiment of the present invention. In other embodiments of the present invention, those skilled in the art may also adjust, optimize and configure the schemes and steps in the above-mentioned embodiments as needed to achieve further technical effects. Other embodiments of the present invention different from the above-mentioned embodiments will be described in conjunction with the accompanying drawings hereinafter. Of course, those skilled in the art may also make appropriate modifications to the execution order, operating conditions and quantity of the steps in the embodiments to be described hereinafter according to actual needs. The modified embodiments do not deviate from the technical concept and / or technical principle of the present invention and should still fall within the scope of protection of the present invention.

[0072] like Figure 3 As shown, in the second embodiment of the present invention, compared with the first embodiment, the power saving control method for air conditioning refrigeration further includes:

[0073] Step S210, in response to the air conditioner 100 being turned on, the current ambient temperature is obtained and recorded as the initial ambient temperature M1.

[0074] Specifically, when the air conditioner 100 is turned on, the current ambient temperature of the room where the air conditioner 100 (specifically, the indoor unit thereof) is located can be detected by a temperature sensor disposed on the indoor unit of the air conditioner 100. The current ambient temperature is then recorded as the initial ambient temperature M1 and stored.

[0075] Those skilled in the art will appreciate that step S210 may be performed simultaneously with step S110.

[0076] Step S220, when the air conditioner 100 is running in the dehumidification mode, the current ambient temperature is obtained in real time and recorded as the real-time ambient temperature M2.

[0077] Step S230, determining whether the difference between the initial ambient temperature M1 and the real-time ambient temperature M2 is less than or equal to a temperature threshold.

[0078] Specifically, is it determined that M1-M2≤temperature threshold? That is, is it determined that M2≥M1-temperature threshold?

[0079] In this embodiment, when M1-M2≤temperature threshold, it means that the air conditioner 100 has reached the temperature reduction limit in the dehumidification mode and cannot continue to cool the environment, or the cooling rate is very low.

[0080] For this purpose, the temperature threshold may be a specific value, such as 3°C, 5°C, 7°C, etc. The temperature threshold may also be related to M1, for example, when M1 is any value between 38°C and 40°C, the temperature threshold is 10°C; when M1 is any value between 35°C and 38°C, the temperature threshold is 7°C; when M1 is any value between 30°C and 35°C, the temperature threshold is 5°C; when M1 is any value between 25°C and 30°C, the temperature threshold is 3°C.

[0081] Step S240: If it is less than or equal to, control the air conditioner 100 to switch from the dehumidification mode to the cooling mode to ensure the cooling efficiency of the air conditioner 100 to its environment.

[0082] Step S250, determining whether the current ambient humidity H1 is less than or equal to the user's suitable humidity H0.

[0083] In the present invention, the air conditioner 100 always detects the current ambient humidity H1 of the environment in which it is located during operation.

[0084] The suitable humidity H0 may be pre-stored on the air conditioner 100 or any feasible device such as a remote controller, a cloud server, or a backend server that is connected to the air conditioner 100. Furthermore, the suitable humidity H0 may be set by the user or by the manufacturer.

[0085] Furthermore, in this embodiment, the suitable humidity H0 may be a specific value or a value range.

[0086] When the suitable humidity H0 is a specific value, it can be 45%, 50%, 52%, 60% and so on.

[0087] When the suitable humidity H0 is a numerical range, it can be 40% to 50%, 45% to 60%, 45% to 50%, etc.

[0088] When the suitable humidity H0 is a numerical range, step S220 specifically determines whether the current ambient humidity H1 is less than or equal to the smallest numerical value within the numerical range of the suitable humidity H0.

[0089] Step S260: If it is less than or equal to, control the air conditioner 100 to start the humidification function. Please refer to the description of step S140 above for details.

[0090] Based on the foregoing description, those skilled in the art can understand that, in the second embodiment of the present invention, when the air conditioner 100 is turned on, the current ambient temperature is obtained and recorded as the initial ambient temperature M1; then, when the air conditioner 100 is running in the dehumidification mode, the current ambient temperature is obtained in real time and recorded as the real-time ambient temperature M2, and it is determined whether the difference between the initial ambient temperature M1 and the real-time ambient temperature M2 is less than or equal to the temperature threshold. If it is less than or equal to, it means that the air conditioner 100 has reached the cooling limit in the dehumidification mode, and the air conditioner 100 is controlled to switch from the dehumidification mode to the cooling mode, so that the air conditioner 100 can continue to cool the environment.

[0091] like Figure 4 As shown, in the third embodiment of the present invention, the air conditioner 100 further includes a vibrator 130, which is configured to vibrate the fins 111 of the evaporator 110 when in operation. For this purpose, the vibrator 130 can be any feasible vibration device, such as an ultrasonic generator, a rotor vibration motor, a linear vibration motor, etc. If the vibrator 130 is a linear vibration motor, the vibration direction of the linear vibration motor is parallel to the thickness direction of the fin 111.

[0092] Under the condition that each fin 111 can generate vibration, those skilled in the art can configure one vibrator 130 or multiple vibrators 130 for the air conditioner 100 as needed. For example, all the fins 111 are divided into N (natural number) groups, and one vibrator 130 is configured for each group of fins 111.

[0093] like Figure 5 As shown, compared with any of the previous embodiments, in the third embodiment of the present invention, the power-saving control method for air-conditioning refrigeration also includes: in response to the air conditioner 100 running in the dehumidification mode for a preset period of time, controlling the air conditioner 100 to turn on the vibration function to make the fins 111 of the evaporator 110 of the air conditioner 100 vibrate.

[0094] Among them, “controlling the air conditioner 100 to turn on the vibration function” includes step S310 and step S320, which are as follows:

[0095] Step S310, determining the vibration frequency of the vibrator 130 of the air conditioner 100 according to the current ambient humidity H1;

[0096] Step S320, controlling the vibrator 130 to operate according to the determined vibration frequency.

[0097] In this embodiment, as an example 1, step S310 may further include: f=H1×d

[0098] Wherein, d is the frequency base and is selected from any value between 50 Hz and 1000 Hz.

[0099] For example, if the current ambient humidity H1 is 40%, d is 200 Hz, then the vibration frequency f of the vibrator 130 is 80 Hz.

[0100] In this embodiment, as example 2, step S310 may further include: from a pre-stored current environment humidity-vibration frequency mapping table (such as Figure 5 As shown in FIG. 1 , the vibration frequency corresponding to the current ambient humidity H1 is found, and the found vibration frequency is determined as the vibration frequency of the vibrator 130.

[0101] Among them, the current ambient humidity-vibration frequency mapping table can be stored in the air conditioner 100 or any feasible device such as a remote control connected to the air conditioner 100 for communication, a cloud server, a background service, etc.

[0102] Furthermore, the mapping relationship between the current ambient humidity and the vibration frequency can be determined by repeatedly observing the generation of condensed water and the retention of condensed water on the fins 111.

[0103] For example, if the current ambient humidity H1 is 43%, from the current ambient humidity-vibration frequency mapping table (such as Figure 5As shown in FIG. 1 , it can be determined that the vibration frequency of the vibrator 130 is 150 Hz.

[0104] like Figure 7 As shown, based on Example 1 or Example 2, step S310 may further include:

[0105] Step S311, obtaining the vibration noise of the air conditioner 100.

[0106] Specifically, the vibration noise of the air conditioner 100 may be acquired through a microphone or other sound acquisition module or vibration detection module disposed on the air conditioner 100 .

[0107] Step S312, determining whether the vibration noise is greater than or equal to a preset noise threshold, and executing step S312 when it is greater than or equal to the preset noise threshold, and not taking action when it is less than the preset noise threshold.

[0108] The noise threshold may be any feasible value, such as 30 decibels, 35 decibels, 40 decibels, etc.

[0109] Step S313, if yes, increase or decrease the vibration frequency of the vibrator 130 until the vibration noise is less than the noise threshold.

[0110] Specifically, when the vibration noise is greater than or equal to the preset noise threshold, the vibration frequency of the vibrator 130 is gradually increased according to a preset step size (e.g., 5 Hz, 10 Hz, 20 Hz, 50 Hz, etc.). If the vibration noise is still greater than or equal to the preset noise threshold, the vibration frequency of the vibrator 130 is gradually reduced according to a preset step size (e.g., 5 Hz, 10 Hz, 20 Hz, 50 Hz, etc.) until the vibration noise is less than the noise threshold.

[0111] Alternatively, those skilled in the art may also, as required, first reduce the vibration frequency of the vibrator 130 and then increase it when the vibration noise is greater than or equal to a preset noise threshold.

[0112] Based on the foregoing description, it can be understood by those skilled in the art that, in the third embodiment of the present invention, when the air conditioner 100 runs in the dehumidification mode for a preset time, a certain amount of condensed water has been formed on the evaporator 110 of the air conditioner 100. At this time, by controlling the air conditioner 100 to start the vibration function, the fins 111 of the evaporator 110 can vibrate, promote the flow of condensed water on the fins 111, and prevent the condensed water from being retained on the surface of the fins 111 due to its own viscosity and tension, thereby preventing the condensed water from absorbing too much cold from the evaporator 110. At the same time, the vibrating fins 111 can also loosen foreign matter (such as dust, lint, dust, etc.) adhering to the fins 111 and flow down with the condensed water, thereby preventing the evaporator 110 of the air conditioner 100 from breeding bacteria after long-term use.

[0113] Furthermore, during the vibration of the fin 111, the vibration noise of the air conditioner 100 is obtained, and it is determined whether the vibration noise is greater than or equal to a preset noise threshold, so that if the result is yes, the vibration frequency of the vibrator 130 is increased or decreased until the vibration noise is less than the noise threshold. Therefore, the third embodiment of the present invention also ensures that the vibration of the fin 111 will not affect the user's life, and ensures the user's experience of the air conditioner 100.

[0114] like Figure 8 As shown, in the fourth embodiment of the present invention, the power saving control method for air conditioning refrigeration includes:

[0115] Step S401, the air conditioner 100 is turned on.

[0116] Step S402, obtaining the current ambient humidity H1 and the current ambient temperature of the environment where the air conditioner 100 is located, and recording the current ambient temperature as the initial ambient temperature M1. For details, please refer to the above description of step S110 and step S210.

[0117] Step S403, determine whether the current environmental humidity H1 is greater than a humidity threshold. For details, please refer to the above description of step S120. If yes, execute step S404, and if not, execute at least one of step S407 and step S409.

[0118] Step S404, controlling the air conditioner 100 to operate in a dehumidification mode.

[0119] Step S405, when the air conditioner 100 is running in the dehumidification mode, the current ambient temperature is obtained in real time and recorded as the real-time ambient temperature M2.

[0120] Step S406, determine whether M2≥M1-temperature threshold?

[0121] For the temperature threshold, please refer to the relevant description in step S230.

[0122] Step S407, controlling the air conditioner 100 to operate in the cooling mode.

[0123] Step S408, determining whether the current ambient humidity H1 is less than or equal to the user's suitable humidity H0, and executing step S409 if it is less than or equal to the user's suitable humidity H0, and continuing to execute step S407 if it is greater than the user's suitable humidity H1.

[0124] Step S409, controlling the air conditioner 100 to start the humidification function, for details, please refer to the above description of step S140.

[0125] Since this embodiment has at least the same technical effects as the first embodiment and the second embodiment, its technical effects will not be described separately here.

[0126] like Fig. 9 As shown, in the fifth embodiment of the present invention, the air conditioner also includes a processor 140 and a memory 150, and the memory 150 stores a machine executable program 151. When the processor 140 executes the machine executable program 151, the power saving control method described in any of the above embodiments can be implemented.

[0127] In this embodiment, the memory 150 may include a memory and a non-volatile memory, and provide execution instructions and data to the processor 140. Exemplarily, the memory may be a high-speed random access memory (RAM), and the non-volatile memory may be at least one disk storage.

[0128] In this embodiment, the processor 140 is an integrated circuit chip that has the ability to process signals.
