TECHNICAL FIELD

[0001] The present application belongs to the technical field of air conditioners, and specifically provides an air conditioner and an energy-saving control method for refrigeration thereof. BACKGROUND

[0002] An air conditioner is a device capable of refrigerating an environment, which can provide a cool and comfortable environment for a user in a hot summer. However, the existing air conditioner has a large power consumption when refrigerating an environment.

[0003] The existing air conditioner can refrigerate an environment when operating in a refrigeration mode and a dehumidification mode. Compared with the refrigeration mode, the air conditioner has lower energy consumption when operating in the dehumidification mode. Moreover, compared with the refrigeration mode, the refrigeration temperature can be reduced by about 2-4℃ when the air conditioner operates in the dehumidification mode.

[0004] Therefore, how to provide a comfortable environment for a user by the dehumidification mode of the air conditioner has become a technical problem to be solved in the field. SUMMARY

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

[0006] A further object of the present application is how to make the evaporator of the air conditioner self-clean.

[0007] A further another object of the present application is how to avoid the bacteria breeding of the evaporator of the air conditioner.

[0008] To achieve the above object, the present application provides an energy-saving control method for refrigeration of an air conditioner in a first aspect, comprising:

[0009] obtaining a current environment temperature M1;

[0010] determining a first temperature difference between the current environment temperature M1 and a suitable temperature M0 of a user;

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

[0012] if yes, controlling the air conditioner to operate in a dehumidification mode.

[0013] Optionally, while performing the step of controlling the air conditioner to operate in the dehumidification mode, the energy-saving control method further comprises:

[0014] obtaining a current environment humidity H1;

[0015] judging whether the current environment humidity H1 is less than or equal to a suitable humidity H0 of the user;

[0016] if yes, controlling the air conditioner to start a humidification function.

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

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

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

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

[0021] the first temperature threshold value is 3℃.

[0022] Optionally, while performing the step of controlling the air conditioner to run in the dehumidification mode, the power saving control method further comprises:

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

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

[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 value, controlling the air conditioner 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 value, the power saving control method further comprises:

[0027] If greater than or equal to, controlling the air conditioner to run in the cooling mode.

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

[0029] in the dehumidification mode, determining whether the air conditioner has reached a starting vibration condition;

[0030] If reached, controlling the air conditioner to start a vibration function to make the fins of the evaporator of the air conditioner vibrate.

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

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

[0033] obtaining a current ambient humidity H1;

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

[0035] Control the vibrator to operate at the determined vibration frequency;

[0036] or,

[0037] The step of controlling the air conditioner to activate the ultrasonic function includes:

[0038] The vibration noise of the air conditioner is obtained;

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

[0040] Optionally, the step of determining whether the air conditioner has reached the condition for activation vibration includes:

[0041] Determine whether the cumulative running time of the air conditioner has reached the preset duration.

[0042] In a second aspect, the present invention provides an air conditioner including a processor and a memory, wherein the memory stores a machine-executable program, and the processor, when executing the machine-executable program, is able to implement the power-saving control method described in any one of the first aspects.

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

[0044] Furthermore, since ambient humidity increases as temperature decreases while the moisture content in the air remains constant, and since the air temperature gradually decreases during air conditioning cooling, the ambient humidity may gradually increase during the cooling process. Therefore, this invention controls the air conditioner to activate the humidification function even when the current ambient humidity H1 is less than or equal to the user's suitable humidity H0, further saving energy consumption during air conditioner operation while ensuring user comfort.

[0045] Furthermore, when the current ambient humidity H1 is less than or equal to the humidity threshold, the air conditioner is switched from dehumidification mode to cooling mode to prevent the air from becoming too dry and to ensure user comfort.

[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, the air conditioner is switched from dehumidification mode to cooling mode by controlling the air conditioner to ensure that the air conditioner can quickly cool the environment when the user lowers its set temperature.

[0047] Further, in the dehumidification mode, it is judged whether the air conditioner reaches the starting vibration condition, and when it reaches the starting vibration condition, the vibration function of the air conditioner is controlled to start, the fins of the evaporator of the air conditioner vibrate, the foreign matters (such as dust, lint, dust, etc.) adhered to the fins are loosened and flow down with the condensed water, and the bacteria breeding on the evaporator of the air conditioner after long time use is avoided. At the same time, the vibrating fins can also promote the flow of the condensed water thereon, avoid the condensed water from being retained on the surface of the fins due to the viscosity and tension of the condensed water, and further avoid the condensed water from absorbing too much cold of the evaporator. Therefore, the vibration function of the air conditioner is started to further reduce the energy consumption of the air conditioner during refrigeration.

[0048] Further, the vibration noise of the air conditioner is obtained, and the vibration frequency of the vibrator of the air conditioner is adjusted according to the vibration noise, so as to reduce the vibration frequency of the vibrator when the vibration noise is large, avoid the noise pollution of the air conditioner, and affect the life and rest of the user.

[0066] As shown in Figure 1 The air conditioner 100 (specifically, the indoor unit thereof) includes an evaporator 110 for cooling air entering the air conditioner 100 and a fan 120 for driving the air to circulate between the inside and outside of the air conditioner 100, thereby achieving refrigeration of the room in which the air conditioner 100 is located.

[0067] The air conditioner and the power-saving control method for refrigeration thereof in the present application will be described in detail below with reference to the accompanying drawings and in conjunction with specific embodiments.

[0068] As shown in Figure 2 In the first embodiment of the present application, the power-saving control method for refrigeration of an air conditioner includes:

[0069] Step S110: Obtain the current ambient temperature M1.

[0070] The current ambient temperature M1 of the room in which the air conditioner 100 (specifically, the indoor unit thereof) is located can be detected by a temperature sensor provided on the indoor unit of the air conditioner 100.

[0071] It should be noted that for the convenience of description, the air conditioner 100 described hereinafter refers to the indoor unit of the air conditioner 100 unless otherwise specified.

[0072] Further, in the present embodiment, step S110 can be performed when the air conditioner 100 is turned on. Further, in the present embodiment, step S110 can be performed when the air conditioner 100 is turned on.

[0073] Step S120, determine the first temperature difference between the current environment temperature M1 and the user's suitable temperature M0.

[0074] Wherein, the user's suitable temperature M0 can be pre-stored in the air conditioner 100 or any feasible device such as remote controller, cloud server, background server, etc. in communication connection with the air conditioner 100. Further, the suitable temperature M0 can be set by the user himself or by the manufacturer. Based on this, the suitable temperature M0 can be any feasible temperature such as 25℃.

[0075] Alternatively, the skilled in the art can also determine the suitable temperature M0 according to the user's age, activity state, etc. For example, when the air conditioner 100 detects that the user is in a stationary state, the suitable temperature M0 is determined as 25℃; when the air conditioner 100 detects that the user is in a motion state, the suitable temperature M0 is determined as 21℃; when the air conditioner 100 detects that the user is an old person, the suitable temperature M0 is determined as 27℃.

[0076] In the embodiment, the first temperature difference = M1-M0.

[0077] Step S130, determine whether the first temperature difference is less than the first temperature threshold.

[0078] Wherein, the first temperature threshold can be any feasible value such as 1℃, 3℃, 5℃, etc.

[0079] In the embodiment, the first temperature threshold is preferably 3℃.

[0080] Step S140, if less, control the air conditioner 100 to run in the dehumidification mode.

[0081] Optionally, step S150, if greater than or equal to, control the air conditioner 100 to run in the refrigeration mode.

[0082] Based on the foregoing description, the skilled in the art can understand that in the first embodiment of the present application, by determining the first temperature difference between the current environment temperature M1 and the user's suitable temperature M0, the air conditioner 100 is controlled to run in the dehumidification mode when the first temperature difference is less than the first temperature threshold, so that the air conditioner 100 runs in the dehumidification mode with lower energy consumption under the premise of ensuring user comfort, thereby reducing the energy consumption of the air conditioner 100 when refrigerating.

[0083] It should be noted that the above embodiments of the present application are only a basic embodiment of the present application. In other embodiments of the present application, those skilled in the art can adjust, optimize and configure the schemes and steps in the above embodiments as needed to achieve further technical effects. Other embodiments of the present application different from the above embodiments will be described below in conjunction with the drawings. Of course, those skilled in the art can also appropriately modify the execution order, running conditions and quantity of the steps in the embodiments described below according to actual needs. The modified embodiments will not deviate from the technical concept and / or technical principles of the present application, and still fall within the protection scope of the present application.

[0084] As shown in the second embodiment of the present application, compared with the first embodiment, the air conditioner refrigeration power saving control method further comprises the following steps when step S140 is performed. Figure 3

[0085] Step S210, acquiring the current environment humidity H1.

[0086] Specifically, the current environment humidity H1 of the room where the air conditioner 100 (specifically, the indoor unit thereof) is located can be detected by the humidity sensor arranged on the indoor unit of the air conditioner 100.

[0087] Step S220, determining whether the current environment humidity H1 is less than or equal to the user's suitable humidity H0.

[0088] The suitable humidity H0 can be pre-stored on the air conditioner 100 or any feasible device such as a remote controller, a cloud server, a background server, etc. in communication connection with the air conditioner 100. Further, the suitable humidity H0 can be set by the user or by the manufacturer.

[0089] Further, in the present embodiment, the suitable humidity H0 can be a specific value or a value range.

[0090] When the suitable humidity H0 is a specific value, it can be 45%, 50%, 52%, 60%, etc.

[0091] When the suitable humidity H0 is a value range, it can be 40% to 50%, 45% to 60%, 45% to 50%, etc.

[0092] When the suitable humidity H0 is a value range, step S220 specifically determines whether the current environment humidity H1 is less than or equal to the minimum value in the value range of the suitable humidity H0.

[0093] Step S230, if less than or equal to, controlling the air conditioner 100 to start the humidification function.

[0094] ​In this embodiment, the indoor unit of the air conditioner 100 is equipped with a humidification module. The water source for 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.

[0095] Step S240: Determine whether the current ambient humidity H1 is less than or equal to the humidity threshold.

[0096] The humidity threshold is 30%.

[0097] In addition, those skilled in the art can set the humidity threshold to any other feasible value as needed. For example, when the air conditioner 100 detects that the user in the room is an elderly person, the humidity threshold can be set to 40%.

[0098] Step S250: If less than or equal to, control the air conditioner 100 to switch from dehumidification mode to cooling mode.

[0099] Those skilled in the art will understand that when the current ambient humidity H1 is less than or equal to the humidity threshold, it indicates that the indoor air humidity is low and the user's body begins to feel uncomfortable, such as the user starting to experience dry nose, dry eyes, thirst, dry skin, etc.

[0100] Those skilled in the art will understand that, given a constant moisture content in the air, ambient humidity increases as temperature decreases. Furthermore, since the air temperature gradually decreases during the cooling process of the air conditioner 100, the ambient humidity may gradually increase. Therefore, this invention controls the air conditioner 100 to activate its humidification function even when the current ambient humidity H1 is less than or equal to the user's suitable humidity H0, further saving energy consumption during operation while ensuring user comfort.

[0101] like Figure 4 As shown, in the third embodiment of the present invention, unlike any of the embodiments described above, the energy-saving control method for air conditioning cooling further includes the following while performing step S140:

[0102] Step S310: Determine whether the set temperature M2 of the air conditioner 100 is less than or equal to the suitable temperature M0.

[0103] The set temperature M2 is the temperature set by the user 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, the more cooling capacity the air conditioner 100 needs to provide to its environment, the greater its cooling power, and / or the longer its cooling time.

[0104] Step S320: Determine whether 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.

[0105] wherein the second temperature difference value = M1-M2.

[0106] If the set temperature M2 is less than or equal to the suitable temperature M0, and the second temperature difference value is greater than or equal to the second temperature threshold value, the air conditioner 100 is controlled to switch from the dehumidification mode to the refrigeration mode.

[0107] As can be understood by those skilled in the art, 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 suitable temperature M0 of the user. The reason for this situation can be that the user has lowered the set temperature M2 of the air conditioner 100.

[0108] For example, in actual scenarios, the user has just drunk hot water, just finished exercising, just finished eating, or just finished cooking, and feels hot, so as to lower the set temperature M2 of the air conditioner 100 to further lower the temperature of the room and make the user cool down quickly.

[0109] Further, in the embodiment, the second temperature threshold value can be any feasible value, for example, 1℃, 2℃, 3℃, 5℃, etc.

[0110] As can be understood by those skilled in the art, when the second temperature difference value is greater than or equal to the second temperature threshold value, it means that the current environment temperature M1 and the set temperature M2 needed by the user are greatly different, and the user hopes that the air conditioner 100 can quickly cool down the environment. Therefore, the air conditioner 100 is controlled to switch from the dehumidification mode to the refrigeration mode, which is slower in cooling down the environment.

[0111] It should be noted that the reason why the air conditioner 100 is faster in cooling down the environment in the refrigeration mode is that the fan 120 is higher in speed in the refrigeration mode and lower in speed in the dehumidification mode. The higher the speed of the fan 120, the faster the rate of air circulation between the inside and outside of the air conditioner 100, and the faster the cold produced by the air conditioner 100 spreads to the entire indoor.

[0112] Based on the foregoing description, those skilled in the art can understand that, in the third embodiment of the present application, when the set temperature M2 is less than or equal to the suitable temperature M0, and the second temperature difference value between the current environment temperature M1 and the set temperature M2 is greater than or equal to the second temperature threshold value, by controlling the air conditioner 100 to switch from the dehumidification mode to the refrigeration mode, it is ensured that the air conditioner 100 can quickly cool down the environment when the user lowers the set temperature thereof.

[0113] As Figure 5As shown, in the fourth embodiment of the present invention, the air conditioner 100 further includes a vibrator 130 configured to vibrate the fins 111 of the evaporator 110 during 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 fins 111.

[0114] While ensuring that each fin 111 can generate vibration, those skilled in the art can configure one or more vibrators 130 for the air conditioner 100 as needed. For example, all fins 111 can be grouped into N (natural numbers), and a vibrator 130 can be configured for each group of fins 111.

[0115] like Figure 6 As shown, compared to any of the previous embodiments, in the fourth embodiment of the present invention, the energy-saving control method for air conditioning cooling further includes:

[0116] Step S410: In dehumidification mode, determine whether the air conditioner 100 has reached the condition for starting vibration.

[0117] The vibration activation condition is that the cumulative operating time of the air conditioner 100 reaches a preset duration. Alternatively, the cumulative rotation time of the fan 120 may reach a preset duration.

[0118] Furthermore, in this embodiment, the cumulative rotation time of the fan 120 is reset to zero after the vibrator 130 stops working.

[0119] Step S420: If the condition is met, control the air conditioner 100 to activate the vibration function, that is, start the vibrator 130 to make the fins 111 of the evaporator 110 of the air conditioner 100 vibrate.

[0120] like Figure 7 As shown, in one example of this embodiment, controlling the air conditioner 100 to activate the vibration function further includes:

[0121] Step S4211: Obtain the current ambient humidity H1.

[0122] Please refer to the previous description of step S210 for details.

[0123] Step S4212: Determine the vibration frequency of the vibrator 130 of the air conditioner 100 based on the current ambient humidity H1.

[0124] Specifically, a current environment humidity-vibration frequency mapping table can be established. For example, in the mapping table, the vibration frequency corresponding to the front environment humidity H1 of 30%-40% is 50Hz, the vibration frequency corresponding to the front environment humidity H1 of 40%-50% is 80Hz, the vibration frequency corresponding to the front environment humidity H1 of 50%-65% is 100Hz, and so on.

[0125] Based on the above current environment humidity-vibration frequency mapping table, after the current environment humidity H1 is determined, the vibration frequency of the vibrator 130 of the air conditioner 100 can be determined.

[0126] It should be noted that the current environment humidity and the vibration frequency can be in a direct proportion relationship or in an inverse proportion relationship.

[0127] In addition, the vibration frequency of the vibrator 130 of the air conditioner 100 can be determined by the following formula: f=H1*d.

[0128] Wherein, d is the frequency base, which can be 500Hz, 300Hz, 250Hz, 200Hz, 150Hz, etc.

[0129] Step S4213, controlling the vibrator 130 to operate according to the determined vibration frequency.

[0130] It can be understood by those skilled in the art that, in the present example, the vibration frequency of the vibrator 130 of the air conditioner 100 is determined by the current environment humidity H1, which can change the vibration frequency of the fin 111 according to the amount of condensate water generated by the evaporator 110, thereby promoting the flow of condensate water thereon and avoiding the condensate water from being retained on the surface of the fin 111 due to its own viscosity and tension effect; further avoiding the condensate water from absorbing too much cold of the evaporator 110. Therefore, the present application further reduces the energy consumption of the air conditioner 100 during refrigeration by enabling the air conditioner 100 to start the vibration function.

[0131] As shown in FIG. 4, in another example of the present embodiment, the control of the air conditioner 100 to start the vibration function further comprises: Figure 8

[0132] Step S4221, obtaining the vibration noise of the air conditioner 100.

[0133] Specifically, the vibration noise of the air conditioner 100 can be obtained by a microphone or other sound acquisition module or vibration detection module arranged on the air conditioner 100.

[0134] Step S4222, adjusting the vibration frequency of the vibrator 130 of the air conditioner 100 according to the vibration noise.

[0135] ​Specifically, when it is detected that the vibration noise of the air conditioner 100 is relatively large or reaches a preset noise threshold (for example, 30 decibels, 35 decibels, 40 decibels, etc.), the vibration frequency of the vibrator 130 is gradually reduced or gradually increased.

[0136] 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.

[0137] Those skilled in the art can understand that the present example can avoid the air conditioner 100 from generating noise pollution and affecting the user's life and rest.

[0138] As shown in FIG. 1, Figure 9 In the fifth embodiment of the present application, the power saving control method of air conditioner refrigeration comprises:
