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℃ to 4℃.

[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 enable the evaporator of an air conditioner to perform self-cleaning.

[0007] Another further object of the present invention is to prevent bacteria from growing on the evaporator of an air conditioner.

[0008] To achieve the above object, the present invention provides, in a first aspect, a power saving control method for air conditioning refrigeration, comprising:

[0009] Get the current ambient temperature M1;

[0010] Determine a first temperature difference between the current ambient temperature M1 and a user's suitable temperature M0;

[0011] Determining whether the first temperature difference is less than a first temperature threshold;

[0012] If it is less than, the air conditioner is controlled to operate in a dehumidification mode.

[0013] Optionally, while executing the step of controlling the air conditioner to operate in the dehumidification mode, the power saving control method further includes:

[0014] Get the current ambient humidity H1;

[0015] Determine whether the current ambient humidity H1 is less than or equal to the user's suitable humidity H0;

[0016] If it is less than or equal to, the air conditioner is controlled to start the humidification function.

[0017] Optionally, after the step of controlling the air conditioner to start a humidification function, the power saving control method further includes:

[0018] Determine whether the current ambient humidity H1 is less than or equal to a humidity threshold;

[0019] If it is less than or equal to, the air conditioner is controlled to switch from the dehumidification mode to the cooling mode.

[0020] Optionally, the humidity threshold is 30%; and / or,

[0021] The first temperature threshold is 3°C.

[0022] Optionally, while executing the step of controlling the air conditioner to operate in the dehumidification mode, the power saving control method further includes:

[0023] Determine whether the set temperature M2 of the air conditioner is less than or equal to the suitable temperature M0;

[0024] Determine whether a second difference between the current ambient temperature M1 and the set temperature M2 is greater than or equal to a second temperature threshold;

[0025] If the set temperature M2 is less than or equal to the suitable temperature M0, and the second temperature difference is greater than or equal to the second temperature threshold, the air conditioner is controlled to switch from the dehumidification mode to the cooling mode.

[0026] Optionally, after the step of determining whether the first temperature difference is less than a first temperature threshold, the power saving control method further includes:

[0027] If it is greater than or equal to, the air conditioner is controlled to operate in cooling mode.

[0028] Optionally, the power saving control method further includes:

[0029] In the dehumidification mode, determining whether the air conditioner has reached a vibration start-up condition;

[0030] If it is reached, the air conditioner is controlled to start a vibration function to vibrate the fins of the evaporator of the air conditioner.

[0031] Optionally, the power saving control method, wherein:

[0032] The step of controlling the air conditioner to start the vibration function includes:

[0033] Get the current ambient humidity H1;

[0034] Determining a vibration frequency of a vibrator of the air conditioner according to the current ambient humidity H1;

[0035] Controlling the vibrator to operate according to the determined vibration frequency;

[0036] or,

[0037] The step of controlling the air conditioner to start the ultrasonic function comprises:

[0038] Obtaining the vibration noise of the air conditioner;

[0039] The vibration frequency of the vibrator of the air conditioner is adjusted according to the vibration noise.

[0040] Optionally, the step of determining whether the air conditioner has reached a vibration start-up condition includes:

[0041] Determine whether the accumulated operation time of the air conditioner has reached a preset time.

[0042] 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.

[0043] Based on the foregoing description, those skilled in the art will be able to understand that, in the aforementioned technical solution of the present invention, by determining the first temperature difference between the current ambient temperature M1 and the user's suitable temperature M0, when the first temperature difference is less than the first temperature threshold, the air conditioner is controlled to operate in the dehumidification mode, so that the air conditioner can operate in a dehumidification mode with lower energy consumption while ensuring the user's comfort, thereby reducing the energy consumption of the air conditioner during cooling.

[0044] Furthermore, since the ambient humidity will increase as the temperature decreases when the moisture content in the air remains unchanged, and since the temperature of the air will gradually decrease during the cooling process of the air conditioner, the ambient humidity may gradually increase during the cooling process of the air conditioner. Therefore, when the current ambient humidity H1 is less than or equal to the user's suitable humidity H0, the present invention still controls the air conditioner to start the humidification function, further saving energy consumption during the operation of the air conditioner, while also ensuring the comfort of the user.

[0045] Furthermore, when the current ambient humidity H1 is less than or equal to the humidity threshold, the air conditioner is controlled to switch from the dehumidification mode to the cooling mode, thereby avoiding excessive air dryness and ensuring the comfort of the user.

[0046] Furthermore, when the set temperature M2 is less than or equal to the suitable temperature M0, and when the second temperature difference between the current ambient temperature M1 and the set temperature M2 is greater than or equal to the second temperature threshold, by controlling the air conditioner to switch from the dehumidification mode to the cooling mode, it is ensured that the air conditioner can quickly cool the environment when the user lowers its set temperature.

[0047] Furthermore, in the dehumidification mode, by judging whether the air conditioner has reached the vibration start-up condition, and when it has reached the condition, controlling the air conditioner to start the vibration function, the fins of the air conditioner's evaporator vibrate, so that foreign matter (such as dust, lint, dust, etc.) adhering to the fins loosens and flows down with the condensed water, thereby preventing the evaporator of the air conditioner from breeding bacteria after long-term use. At the same time, the vibrating fins can also promote the flow of condensed water thereon, 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. Therefore, the present invention further reduces the energy consumption of the air conditioner during cooling by turning on the vibration function of the air conditioner.

[0048] Furthermore, by obtaining the vibration noise of the air conditioner and adjusting the vibration frequency of the vibrator of the air conditioner according to the vibration noise, the vibration frequency of the vibrator can be reduced when the vibration noise is large, thereby avoiding noise pollution caused by the air conditioner and affecting the user's life and rest.

[0049] 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.

[0062] 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.

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.

[0067] 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.

[0068] 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.

[0069] like Figure 2 As shown, in the first embodiment of the present invention, the power saving control method for air conditioning refrigeration includes:

[0070] Step S110, obtaining the current ambient temperature M1.

[0071] Specifically, the current ambient temperature M1 of the room where the air conditioner 100 (specifically, the indoor unit thereof) is located may be detected by a temperature sensor disposed on the indoor unit of the air conditioner 100 .

[0072] It should be noted that, for the convenience of description, the air conditioner 100 described below generally refers to the indoor unit of the air conditioner 100 unless otherwise specified.

[0073] Further, in this embodiment, step S110 may be executed when the air conditioner 100 is turned on.

[0074] Step S120, determining a first temperature difference between the current ambient temperature M1 and the user's suitable temperature M0.

[0075] The user's suitable temperature M0 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. Further, the suitable temperature M0 may be set by the user or by the manufacturer. Based on this, the suitable temperature M0 may be any feasible temperature such as 25°C.

[0076] Alternatively, those skilled in the art may also determine the appropriate temperature M0 according to the user's age and activity status as needed. For example, when the air conditioner 100 detects that the user is stationary, the appropriate temperature M0 is determined to be 25°C; when the air conditioner 100 detects that the user is in motion, the appropriate temperature M0 is determined to be 21°C; when the air conditioner 100 detects that the user is an elderly person, the appropriate temperature M0 is determined to be 27°C.

[0077] In this embodiment, the first temperature difference=M1-M0.

[0078] Step S130, determining whether the first temperature difference is less than a first temperature threshold.

[0079] The first temperature threshold may be any feasible value, such as 1° C., 3° ​​C., 5° C., etc.

[0080] In this embodiment, the first temperature threshold is preferably 3°C.

[0081] Step S140: if it is less than, control the air conditioner 100 to operate in the dehumidification mode.

[0082] Optional step S150, if greater than or equal to, control the air conditioner 100 to operate in cooling mode.

[0083] Based on the foregoing description, those skilled in the art will understand that, in the first embodiment of the present invention, by determining a first temperature difference between the current ambient temperature M1 and the user's suitable temperature M0, when the first temperature difference is less than a first temperature threshold, the air conditioner 100 is controlled to operate in a dehumidification mode, so that the air conditioner 100 operates in a dehumidification mode with lower energy consumption while ensuring user comfort, thereby reducing the energy consumption of the air conditioner 100 during cooling.

[0084] 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.

[0085] like Figure 3 As shown, in the second embodiment of the present invention, compared with the first embodiment, while executing step S140, the power saving control method for air conditioning refrigeration further includes:

[0086] Step S210, obtaining the current ambient humidity H1.

[0087] Specifically, the current ambient humidity H1 of the room where the air conditioner 100 (specifically, the indoor unit thereof) is located can be detected by means of a humidity sensor disposed on the indoor unit of the air conditioner 100 .

[0088] Step S220, determining whether the current ambient humidity H1 is less than or equal to the user's suitable humidity H0.

[0089] 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.

[0090] Furthermore, in this embodiment, the suitable humidity H0 may be a specific value or a value range.

[0091] When the suitable humidity H0 is a specific value, it can be 45%, 50%, 52%, 60% and so on.

[0092] When the suitable humidity H0 is a numerical range, it can be 40% to 50%, 45% to 60%, 45% to 50%, etc.

[0093] 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.

[0094] Step S230: if it is less than or equal to, control the air conditioner 100 to turn on the humidification function.

[0095] In this embodiment, 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.

[0096] Step S240, determining whether the current ambient humidity H1 is less than or equal to a humidity threshold.

[0097] Among them, the humidity threshold is 30%.

[0098] 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%.

[0099] Step S250: if it is less than or equal to, control the air conditioner 100 to switch from the dehumidification mode to the cooling mode.

[0100] Those skilled in the art can understand that when 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.

[0101] It is understood by those skilled in the art that, since the ambient humidity will increase as the temperature decreases when the moisture content in the air remains unchanged, and since the temperature of the air will gradually decrease during the cooling process of the air conditioner 100, the ambient humidity may gradually increase during the cooling process of the air conditioner 100. For this reason, the present invention still controls the air conditioner 100 to start the humidification function when the current ambient humidity H1 is less than or equal to the user's suitable humidity H0, further saving energy consumption during the operation of the air conditioner 100, while also ensuring the comfort of the user.

[0102] like Figure 4 As shown, in the third embodiment of the present invention, different from any of the embodiments described above, while executing step S140, the power saving control method for air conditioning refrigeration further includes:

[0103] Step S310, determining whether the set temperature M2 of the air conditioner 100 is less than or equal to the appropriate temperature M0.

[0104] The set temperature M2 is a temperature set by the user and is used to control the operation of the air conditioner 100. Those skilled in the art should understand that the lower the set temperature M2 of the air conditioner 100 is, the more cooling capacity the air conditioner 100 needs to provide for the environment in which it is located, the greater the cooling power of the air conditioner 100 is and / or the longer the cooling time is.

[0105] Step S320, determining whether a second difference between the current ambient temperature M1 and the set temperature M2 is greater than or equal to a second temperature threshold.

[0106] Wherein, the second difference = M1 - M2.

[0107] Step S330: If the set temperature M2 is less than or equal to the appropriate temperature M0, and the second temperature difference is greater than or equal to the second temperature threshold, the air conditioner 100 is controlled to switch from the dehumidification mode to the cooling mode.

[0108] Those skilled in the art will appreciate that if the set temperature M2 is less than or equal to the suitable temperature M0, it means that the set temperature M2 of the air conditioner 100 is below the user's suitable temperature M0. This may be because the user has lowered the set temperature M2 of the air conditioner 100.

[0109] For example, in an actual scenario, a user may feel hot after drinking hot water, exercising, eating, or cooking, and thus lower the set temperature M2 of the air conditioner 100 to further reduce the temperature in the room and cool the user quickly.

[0110] Further, in this embodiment, the second temperature threshold may be any feasible value, such as 1° C., 2° C., 3° ​​C., 5° C., etc.

[0111] Those skilled in the art can understand that when the second temperature difference is greater than or equal to the second temperature threshold, it means that the current ambient temperature M1 is significantly different from the set temperature M2 required by the user, and the user hopes that the air conditioner 100 can quickly cool down the environment. To this end, the air conditioner 100 is controlled to switch from the dehumidification mode that cools down the environment more slowly to the cooling mode that cools down the environment more quickly.

[0112] It should be noted that the reason why the air conditioner 100 cools down the environment faster when operating in the cooling mode is that the fan 120 rotates at a higher speed when operating in the cooling mode and rotates at a lower speed when operating in the dehumidification mode. The higher the speed of the fan 120, the faster the air circulates inside and outside the air conditioner 100, so that the cooling energy generated by the air conditioner 100 spreads to the entire room faster.

[0113] Based on the foregoing description, those skilled in the art will understand that, in the third embodiment of the present invention, when the set temperature M2 is less than or equal to the suitable temperature M0, and when the second temperature difference between the current ambient temperature M1 and the set temperature M2 is greater than or equal to the second temperature threshold, by controlling the air conditioner 100 to switch from the dehumidification mode to the cooling mode, it is ensured that the air conditioner 100 can quickly cool the environment when the user lowers its set temperature.

[0114] like Figure 5As shown, in the fourth 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.

[0115] 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.

[0116] like Figure 6 As shown, compared with any of the above embodiments, in the fourth embodiment of the present invention, the power saving control method for air conditioning refrigeration further includes:

[0117] Step S410: In the dehumidification mode, it is determined whether the air conditioner 100 has reached a vibration start condition.

[0118] The vibration start condition is that the cumulative operation time of the air conditioner 100 reaches a preset time. Further, the cumulative rotation time of the fan 120 reaches a preset time.

[0119] Furthermore, in this embodiment, the accumulated rotation time of the fan 120 is reset to zero after the vibrator 130 stops working.

[0120] Step S420 , if reached, control the air conditioner 100 to start the vibration function, that is, start the vibrator 130 to vibrate the fins 111 of the evaporator 110 of the air conditioner 100 .

[0121] like Figure 7 As shown, in an example of this embodiment, controlling the air conditioner 100 to turn on the vibration function further includes:

[0122] Step S4211, obtaining the current ambient humidity H1.

[0123] Please refer to the above description of step S210 for details.

[0124] Step S4212, determining the vibration frequency of the vibrator 130 of the air conditioner 100 according to the current ambient humidity H1.

[0125] Specifically, a current ambient humidity-vibration frequency mapping table may be established. For example, in the mapping table, the vibration frequency corresponding to the previous ambient humidity H1 of 30%-40% is 50Hz, the vibration frequency corresponding to the previous ambient humidity H1 of 40%-50% is 80Hz, the vibration frequency corresponding to the previous ambient humidity H1 of 50%-65% is 100Hz, and so on.

[0126] Based on the current ambient humidity-vibration frequency mapping table, after the current ambient humidity H1 is determined, the vibration frequency of the vibrator 130 of the air conditioner 100 can be determined.

[0127] It should be noted that the current ambient humidity and the vibration frequency may be in direct proportion or in inverse proportion.

[0128] In addition, the vibration frequency of the vibrator 130 of the air conditioner 100 may be determined by the following formula: f=H1*d.

[0129] Among them, d is the frequency base, which can be 500Hz, 300Hz, 250Hz, 200Hz, 150Hz, etc.

[0130] Step S4213, controlling the vibrator 130 to operate according to the determined vibration frequency.

[0131] Those skilled in the art can understand that, in this example, the vibration frequency of the vibrator 130 of the air conditioner 100 is determined by the current ambient humidity H1, so that the vibration frequency of the fin 111 can be changed with the amount of condensed water generated by the evaporator 110, thereby promoting the flow of condensed water thereon, and preventing the condensed water from being retained on the surface of the fin 111 due to its own viscosity and tension; thereby preventing the condensed water from absorbing too much cold of the evaporator 110. Therefore, the present invention further reduces the energy consumption of the air conditioner 100 during cooling by turning on the vibration function of the air conditioner 100.

[0132] like Figure 8 As shown, in another example of this embodiment, controlling the air conditioner 100 to turn on the vibration function further includes:

[0133] Step S4221, obtaining the vibration noise of the air conditioner 100.

[0134] 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 .

[0135] Step S4222, adjusting the vibration frequency of the vibrator 130 of the air conditioner 100 according to the vibration noise.

[0136] Specifically, when it is detected that the vibration noise of the air conditioner 100 is relatively large or reaches a preset noise threshold (eg, 30 decibels, 35 decibels, 40 decibels, etc.), the vibration frequency of the vibrator 130 is gradually reduced or increased.

[0137] Further, after the vibration frequency of the vibrator 130 is reduced or increased, if the vibration noise of the air conditioner 100 is still not reduced, the vibration frequency of the vibrator 130 is increased or reduced in the opposite direction until the vibration noise of the air conditioner 100 is reduced below the noise threshold.

[0138] Those skilled in the art can understand that this example can prevent the air conditioner 100 from generating noise pollution and affecting the user's life and rest.

[0139] like Fig. 9 As shown, in the fifth embodiment of the present invention, the power saving control method for air conditioning refrigeration includes:

[0140] Step S501, obtaining the current ambient temperature M1, for details please refer to the above description of step S110.

[0141] In this embodiment, step S501 may be executed when the air conditioner 100 is turned on.

[0142] Step S502, determine whether the current environment temperature M1 is less than or equal to the user's suitable temperature M0. If not, execute step S503, if yes, execute step S507.

[0143] Step S503, determining a first temperature difference between the current ambient temperature M1 and the user's suitable temperature M0, for details, please refer to the above description of step S120.

[0144] Step S504, determining whether the first temperature difference is less than the first temperature threshold, for details, please refer to the above description of step S130. If not, execute step S505, and if yes, execute step S506.

[0145] Step S505, controlling the air conditioner 100 to operate in a cooling mode.

[0146] Step S506, controlling the air conditioner 100 to operate in a dehumidification mode.

[0147] Step S507, making the air conditioner 100 run at the current operating parameters.

[0148] Step S508: the air conditioner 100 receives a user's instruction to lower the set temperature.
