Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and in particular to an air conditioner and its control method. Background Technology

[0002] Currently, indoor air quality is mainly plagued by three major problems: bacteria, oil stains, and formaldehyde. For example, mold growth in air conditioners and harmful bacteria in humidifiers can cause unpleasant odors; cooking fumes can cause oil stains on the fins, leading to a decrease in indoor air quality; and formaldehyde, heavy metal particles, and PM2.5 produced during new home renovations are highly latent, have long release periods, and are highly toxic, potentially causing damage to the nervous system, coughing, chest tightness, immune system abnormalities, tissue cancer, and even death.

[0003] Currently, common purification methods for addressing the "three major problems" of indoor air pollution can be broadly categorized into physical and chemical methods. Physical sterilization often utilizes high temperatures, ultraviolet light, HEPA filtration, and low-temperature plasma technology, resulting in short-lived sterilization effects but easily disrupting the microecological balance. Chemical sterilization often employs catalysts, which can easily lead to secondary pollution. Physical degreasing often uses fiber filtration and water washing, while chemical degreasing commonly uses detergents; both methods are inefficient at removing grease and easily breed bacteria. Physical formaldehyde removal often uses adsorption technologies such as activated carbon, which can reach adsorption saturation and easily cause secondary pollution; chemical formaldehyde removal often uses bonding technologies such as potassium permanganate chemical reactions, resulting in slow formaldehyde removal speeds. Therefore, existing purification methods are inefficient at removing bacteria, grease, and formaldehyde and are prone to causing secondary pollution, failing to meet the air purification requirements of air conditioners. Summary of the Invention

[0052] See Figure 1 This is a structural schematic diagram of an air conditioner provided in an embodiment of the present invention.

[0053] The air conditioner 100 of the present invention includes an indoor unit 30. Taking a wall-mounted indoor unit (shown in the figure) as an example, the indoor unit is usually installed on an indoor wall such as a wall panel (WL). Another example is a floor-standing indoor unit (not shown in the figure), which is also a form of indoor unit 30. The air conditioner 100 also includes an outdoor unit 20; the outdoor unit 20 is usually installed outdoors and is used for heat exchange in the indoor environment. Furthermore, in... Figure 1 In the diagram, outdoor unit 20, located outdoors on the opposite side of indoor unit 30 across wall WL, is represented by a dashed line. Outdoor unit 20 is connected to indoor unit 30 via connecting pipe 40. Furthermore, as... Figure 1 As shown, the air conditioner 100 also includes a remote control 50, which has the following functions: Figure 1 The liquid crystal display device 5a and button 5b shown are included. The remote control 50 has the function of communicating with the controller 60 of the air conditioner 100, for example, using infrared or other communication methods. The remote control 50 is used by the user to perform various controls on the air conditioner 100, realizing interaction between the user and the air conditioner 100.

[0054] In one specific embodiment, the air conditioner 100 further includes a refrigeration system; wherein the refrigeration system comprises a compressor, a four-way valve, an outdoor heat exchanger, a throttling device, and an indoor heat exchanger connected in sequence; specifically, in the refrigeration system, the discharge port of the compressor is connected to the first end of the four-way valve, the second end of the four-way valve is connected to the first end of the outdoor heat exchanger, the second end of the outdoor heat exchanger is connected to the first end of the throttling device, the second end of the throttling device is connected to the first end of the indoor heat exchanger, the second end of the indoor heat exchanger is connected to the third end of the four-way valve, and the fourth end of the four-way valve is connected to the suction port of the compressor. Specifically, the throttling device is an electronic expansion valve.

[0055] Further, see Figure 2The air conditioner 100 also includes a probiotic purification device 10; wherein, the probiotic purification device 10 is located at the air inlet of the indoor unit 30 and is used to spray probiotic cleaning agent; specifically, the probiotic purification device 10 includes an atomizer and a driving device; the atomizer is used to spray probiotic cleaning agent under the driving device; the driving device includes at least a drive module and a driving module for driving the atomizer to spray probiotic cleaning agent, the driving module being controlled by the drive module; a controller 60 is connected to the drive module to control the drive module. Specifically, the controller 60 is used for:

[0056] When the air conditioner 100 enters the sterilization mode, the drive module is controlled to drive the push module to push the atomizer to spray probiotic cleaning agent at a preset sterilization frequency until the air conditioner 100 meets the preset sterilization stop condition and exits the sterilization mode.

[0057] When the air conditioner 100 enters the degreasing mode, the drive module is controlled to drive the push module to push the atomizer to release probiotic cleaner at a preset degreasing frequency until the air conditioner 100 meets the preset degreasing stop condition and exits the degreasing mode.

[0058] When the air conditioner 100 enters the formaldehyde removal mode, the drive module is controlled to drive the push module to push the atomizer to release probiotic cleaning agent at a preset formaldehyde removal frequency until the air conditioner 100 meets the preset formaldehyde removal stop condition and exits the formaldehyde removal mode.

[0059] The air conditioner 100 provided in this embodiment of the invention employs a probiotic biological method. A probiotic purification device 10 is installed at the air inlet of the indoor unit 30. Probiotic cleaning agents are sprayed before the air passes through the air purification device of the air conditioner 100. Utilizing the rapid reproduction rate of probiotics, it quickly eliminates the living space of harmful bacteria, achieving a sterilization effect. Simultaneously, probiotics can secrete various highly active digestive enzymes to dissolve stubborn biofilms, thus removing oil stains. Furthermore, the probiotic immobilization method effectively degrades formaldehyde, achieving a formaldehyde removal effect. This achieves balanced purification of the air introduced by the air conditioner 100, effectively and long-lastingly inhibiting mold, oil stains, and formaldehyde in the air conditioner 100 and the air it introduces. This improves the efficiency of sterilization, oil stain removal, and formaldehyde removal, effectively avoiding secondary pollution, thus meeting the air purification requirements of the air conditioner 100 and ensuring indoor air purification quality.

[0060] Specifically, the controller 60 is also used to: control the air conditioner 100 to enter the sterilization mode when the air conditioner 100 meets the preset sterilization start conditions; control the air conditioner 100 to enter the oil removal mode when the air conditioner 100 meets the preset oil removal start conditions; and control the air conditioner 100 to enter the formaldehyde removal mode when the air conditioner 100 meets the preset formaldehyde removal start conditions.

[0061] It should be noted that the preset sterilization start conditions, preset oil removal start conditions, and preset formaldehyde removal start conditions can be set according to actual conditions, such as how long the air conditioner 100 runs to perform sterilization, oil removal, and formaldehyde removal, or the user controls the air conditioner 100 to enter sterilization mode, oil removal mode, and formaldehyde removal mode through remote control 50, etc., and these are not limited here.

[0062] Specifically, the preset sterilization stop condition is when the air conditioner 100 operates continuously in the sterilization mode for a preset sterilization time.

[0063] Specifically, the preset oil removal stop condition is when the continuous operating time of the air conditioner 100 in the oil removal mode reaches the preset oil removal time.

[0064] Furthermore, the air conditioner 100 also includes an air detection device; wherein, the air detection device is installed on the indoor unit 30 and is used to detect the formaldehyde concentration in the indoor air; the controller 60 is also connected to the air detection device to receive the formaldehyde concentration detected by the air detection device. Therefore, the preset formaldehyde removal stop condition is specifically as follows:

[0065] The air conditioner 100 operates continuously in the sterilization mode for a period of time that reaches the preset formaldehyde removal time, and the formaldehyde concentration detected by the air detection device is less than the preset concentration threshold.

[0066] It should be noted that the preset sterilization time, preset oil removal time, and preset formaldehyde removal time can be set before leaving the factory. Optionally, in the sterilization mode set before leaving the factory, the preset sterilization time is 20 minutes, which means the probiotic spray release time is 20 minutes.

[0067] For example, see Figure 4 It is evident that probiotics, by utilizing their rapid reproduction rate, can quickly establish a dominant bacterial population. Through the preemptive effect and nutrient competition, they can deprive harmful bacteria of their nutrient sources, squeezing out their living space and achieving effective sterilization while also preventing secondary contamination. Furthermore, because probiotics can secrete various highly active digestive enzymes, they can dissolve stubborn biofilms, thus achieving a degreasing effect. See also... Figure 5 It is evident that probiotics are bacteria with the potential to degrade formaldehyde, and therefore, microbial immobilization methods can be used to effectively degrade formaldehyde.

[0068] For example, combined Figure 6 The diagram shows the workflow of a controller 60 provided in an embodiment of the present invention. The control process of the controller 60 is as follows: the air conditioner 100 enters the sterilization mode (step S11), and then executes step S12; the control drive module drives the push module to push the atomizer to spray probiotic cleaner at a preset sterilization frequency (step S12), and then executes step S13; it is determined whether the continuous running time of the air conditioner 100 in the sterilization mode has reached the preset sterilization time (step S13). If yes, step S14 is executed; otherwise, step S12 is returned; the sterilization mode is exited (step S14), and the sterilization process ends. The air conditioner 100 enters the degreasing mode (step S21), and then executes step S22; the control drive module drives the push module to push the atomizer to release probiotic cleaner at a preset degreasing frequency (step S22), and then executes step S23; it is determined whether the continuous running time of the air conditioner 100 in the degreasing mode has reached the preset degreasing time (step S23), and then executes step S24; the degreasing mode is exited (step S24), and the current degreasing process ends. The air conditioner 100 enters the formaldehyde removal mode (step S31), and then executes step S32; the control drive module drives the push module to push the atomizer to release probiotic cleaner at a preset formaldehyde removal frequency (step S32), and then executes step S33 to determine whether the continuous running time of the air conditioner 100 in the sterilization mode has reached the preset formaldehyde removal time (step S33). If yes, execute step S34; otherwise, return to step S32; determine whether the formaldehyde concentration detected by the air detection device is less than the preset concentration threshold (step S34). If yes, execute step S35; otherwise, return to step S32; exit the formaldehyde removal mode (step S35), and this formaldehyde removal process ends.

[0069] See Figure 5 As one specific embodiment, the pushing module specifically includes:

[0070] The push rod has one end abutting against the atomizer and the other end passing through the limiting block 101 with a limiting hole and connecting to the ferrite 102; wherein, the limiting block 101 is provided with a magnet 103 and a metal coil 104 on the side near the ferrite 102, and the metal coil 104 is wound around the ferrite 102 and connected to the drive module.

[0071] A motion guide mechanism is fixed to the side of the ferrite 102 away from the limiting block 101, and is used for motion guidance of pushing and resetting the ferrite 102.

[0072] Understandably, the magnet 103, which is fixed in the limiting block 101, is used to provide magnetic attraction for the movement of the ferrite 102.

[0073] Specifically, the metal coil 104 is a copper coil.

[0074] See Figure 5 As one specific embodiment, the pushing module further includes:

[0075] A hollow guide rail 105 is fitted onto the outer surface of a metal coil 104, with one end fixed to a limiting block 101.

[0076] Furthermore, the hollow guide rail 105 is fixed to one end of the limiting block 101 and is provided with a claw mechanism, which fixes the metal coil 104 by interference fit.

[0077] Specifically, the hollow guide rail 105 is made of flexible polyurethane material. The hollow guide rail 105 is fixed to the limiting block 101 by screws. The hollow guide rail 105 is used to provide motion guidance for the ferrite 102.

[0078] See Figure 5 As one specific implementation, the motion guiding mechanism includes:

[0079] Fixed block 106;

[0080] A pair of slide rails 107 are set opposite to each other;

[0081] The slider 108 is slidably connected to the slide rail 107 on both sides;

[0082] A tension spring 109 has a fixed block 106 and a slider 108 connected to its two ends, respectively, and is used to pull the slider 108 along the slide rail 107 toward the fixed block 106; wherein, the side of the slider 108 away from the fixed block 106 is fixed to the ferrite 102.

[0083] Specifically, ferrite 102, with its two ends glued to slider 108 and push rod respectively, is used to provide power for pushing the push rod.

[0084] Understandably, the slider 108 and the ferrite 102 are connected by adhesive bonding, and mechanical operations such as drilling holes in the ferrite 102 are not permitted, as such operations could easily damage its magnetic properties. The slider 108 is connected to the grooves of the slide rail 107 on both sides, and slides within the slide rail 107. The tension spring 109 provides tension for the movement of the ferrite 102, thereby enabling the motion guide mechanism to guide the ferrite 102 in both pushing and resetting motion.

[0085] Specifically, slide rail 107 is an I-shaped slide rail.

[0086] See Figure 7 and 8 Specifically, the atomizer includes:

[0087] Liquid storage device 110 is used to store probiotic cleaning agent;

[0088] Atomizing head 111 is disposed on liquid storage device 110 and is used to spray the probiotic cleaner under the push of the pushing device.

[0089] Furthermore, the atomizer also includes at least two limiting brackets 118; wherein, the limiting brackets 118 are disposed opposite to each other on the outer wall of the liquid storage device 110, and the limiting brackets 118 are used to fix the rotational position of the atomizer to ensure the optimal spray angle.

[0090] Furthermore, the probiotic purification device 10 also includes a base 112 and a card holder 113; wherein the base 112 and the card holder 113 are connected and fixed to the atomizer by a snap-fit ​​connection.

[0091] Understandably, the base 112 is used for fixing and limiting the atomizer.

[0092] Furthermore, the push rod includes a push rod body 114 and a push head 115; wherein the push rod body 114 is threadedly connected to the push head 115, and the push head 115 abuts against the atomizer.

[0093] Understandably, the push rod is used to push the atomizing head 111, causing the atomizer to release the probiotic cleaner.

[0094] See Figure 9 and 10 In one specific implementation, the driving module includes a signal generation unit 116 and a power amplification unit 117; wherein,

[0095] The signal generating unit 116 has its output terminal connected to the input terminal of the power amplification unit 117, and is used to generate current signals of different frequencies.

[0096] The power amplifier unit 117, whose output terminal is connected to the metal coil 104, is used to amplify the current signal emitted by the signal generating unit 116 to drive the driving device to generate a thrust to drive the atomizer under electromagnetic action.

[0097] It is worth noting that, see Figure 7-10In this embodiment of the invention, the probiotic purification device 10 utilizes the electromagnetic induction effect. A current of arbitrary waveform is loaded by the signal generation unit 116 and conducted to the metal coil 104 via the power amplification unit 117. This generates an induced magnetic field in the space surrounding the metal coil 104. When this induced magnetic field acts on the ferrite 102, the internal magnetic walls of the ferrite 102 expand, and the magnetic domains turn towards the direction of the induced magnetic field, thus becoming magnetized. This makes the ferrite 102 macroscopically magnetic. Therefore, after being magnetized, the ferrite 102 accelerates towards the magnet 103 under the magnetic attraction of the magnet 103, causing the pusher 115 connected to the end of the ferrite 102 to push the atomizing head 111 of the atomizer, releasing the probiotic cleaner. It should be noted that the frequency and time of the atomizer releasing the probiotic cleaner can be determined by the waveform of the current loaded by the signal generation unit 116. For example, square waves with the same pulse width but different frequencies.

[0098] Furthermore, the base 112, the limiting block 101, the slide rail 107, and the fixing block 106 are all integrated into the outer casing of the indoor unit 30.

[0099] Understandably, the preset sterilization frequency, preset oil removal frequency, and preset formaldehyde removal frequency can be understood as the release frequency of the probiotic spray, i.e., the pushing frequency of the push rod, which can be realized according to the waveform of the signal generation unit 116 (e.g., square wave). The specific values ​​of the preset sterilization frequency, preset oil removal frequency, and preset formaldehyde removal frequency in actual operation can be set by the factory or determined by the user. Optionally, the preset sterilization frequency corresponds to a probiotic spray release frequency of 5 times / min.

[0100] The air conditioner control method provided in this embodiment of the invention is applied to the air conditioner described in any of the above embodiments and is executed by a controller; the method includes:

[0101] When the air conditioner enters the sterilization mode, the drive module is controlled to drive the push module to push the atomizer to spray probiotic cleaning agent at a preset sterilization frequency until the air conditioner meets the preset sterilization stop condition and exits the sterilization mode.

[0102] When the air conditioner enters the degreasing mode, the drive module is controlled to drive the push module to push the atomizer to release probiotic cleaner at a preset degreasing frequency until the air conditioner meets the preset degreasing stop condition and exits the degreasing mode.
