Description

Technical Field

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

[0002] Currently, the humidification function of air conditioners is achieved by setting up a water tank and an atomizing device. Users add water to the water tank, and the atomizing device atomizes the water in the tank and then blows it into the air through a fan.

[0003] The system is complex due to the need for a water tank and atomizing device, and requires manual water replenishment, making operation cumbersome and impacting user experience. Furthermore, the atomizing device, located inside the air conditioner, is prone to clogging and dirt buildup after prolonged use, affecting humidification efficiency.

[0004] The applicant has discovered that the existing technology has at least the following technical problems: the air conditioner humidification is achieved by using a water tank and an atomizing device, which requires the user to add water, resulting in a poor user experience. Summary of the Invention

[0005] The purpose of this invention is to provide an air conditioner humidification device, an air conditioner, and a control method, to solve the technical problem in the prior art where air conditioner humidification is achieved using a water tank and atomizing device, requiring users to add water, resulting in a poor user experience. 。 The preferred technical solutions among the many technical solutions provided by this invention can produce a variety of technical effects, which are described in detail below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The humidification device for an air conditioner provided by the present invention includes an air supply channel, an evaporator, a fan and a deflecting ice plate are arranged in the air supply channel, the evaporator is connected to the refrigeration system of the air conditioner, the deflecting ice plate is arranged on one side of the evaporator, and the evaporator and the deflecting ice plate divide the air supply channel to form an S-shaped deflecting channel.

[0008] As a further improvement of the present invention, two flow-guiding ice plates are provided, which are disposed on both sides of the evaporator, and the two flow-guiding ice plates form a U-shaped channel with the evaporator.

[0009] As a further improvement of the present invention, a heat-conducting column is provided between the fluidizing ice plate and the evaporator.

[0010] As a further improvement of the present invention, the heat-conducting columns are arranged in rows between the fluidizing ice plate and the evaporator, and adjacent rows of heat-conducting columns are staggered.

[0011] As a further improvement of the present invention, an air inlet door and an air outlet door are respectively provided on the air inlet and air outlet of the air supply channel for opening and closing the air inlet and the air outlet.

[0012] As a further improvement of the present invention, the fluidizing ice plate and the heat-conducting column are made of aluminum.

[0013] As a further improvement of the present invention, the fan is disposed in the air supply channel near the air outlet.

[0014] An air conditioner includes an air conditioner humidification device as described above.

[0015] A control method for controlling the humidification device of an air conditioner as described above, comprising:

[0016] The system detects the indoor humidity level b. If the detected value b is less than the preset value a, the humidification mode is activated.

[0017] As a further improvement of the present invention, the control method further includes:

[0018] Determine if the humidifier of the air conditioner has a self-cleaning function;

[0019] If so, the indoor humidity value b will be detected. If the detected value b is less than the preset value a, the humidification mode will be activated.

[0020] As a further improvement of the present invention, the dehumidification mode is activated by: controlling the evaporator to be in cooling mode, stopping the fan of the air conditioner humidification device, and causing the evaporator to begin to freeze;

[0021] Check if the evaporator is completely frozen. If so, turn off the evaporator and start the fan of the air conditioner's humidification device to melt the ice on the evaporator and humidify the room.

[0022] Once the ice on the evaporator melts, the evaporator is switched to heating mode to quickly evaporate and vaporize the water on it.

[0023] As a further improvement of the present invention, the control method further includes: if not, activating a self-cleaning mode.

[0024] As a further improvement of the present invention, the self-cleaning mode is activated by: controlling the evaporator to be in cooling mode, stopping the fan of the air conditioner humidification device, and causing the evaporator to begin to freeze;

[0025] If the evaporator is completely frozen, the system will quickly switch the evaporator to heating mode to melt the ice quickly. The ice will then carry away the dust as it peels off the evaporator.

[0026] As a further improvement of the present invention, if not, the self-cleaning mode is activated, the method further includes: if the air conditioner humidifier has not activated the self-cleaning mode after a preset time T2 of operation, then the air conditioner humidifier activates the self-cleaning mode.

[0027] As a further improvement of the present invention, if not, the self-cleaning mode is activated, including: after the air conditioner humidifier has been running for a preset time T1, a self-cleaning command is issued to manually activate the self-cleaning mode of the air conditioner humidifier.

[0028] The beneficial effects of this invention are as follows: The air conditioner humidification device provided by this invention includes an air supply channel, in which an evaporator is installed. The evaporator is connected to the air conditioner's refrigeration system. The refrigeration system can control the evaporator to freeze through a four-way valve component. After freezing, the fan operates to deliver air into the room, carrying the condensed water on the evaporator into the room, thereby achieving the humidification function. Using the above structure, there is no need to install a water tank and atomizing device, and no need to add extra water, which improves the user experience and also enables fresh air exchange. Secondly, the evaporator can be cleaned during rapid defrosting after freezing, achieving self-cleaning. Furthermore, the de-icing plate is located on one side of the evaporator. The evaporator and the de-icing plate separate the air supply channel into an S-shaped de-icing channel. The de-icing channel increases the contact area between the ambient air delivered by the fan and the ice on the evaporator and the de-icing plate, thereby improving the defrosting efficiency and humidification effect.

[0029] Furthermore, the two sets of de-icing plates form a U-shaped channel with the evaporator, which can increase the contact area between the ambient air delivered by the fan and the ice on the evaporator and the de-icing plates, thereby improving the de-icing efficiency and enhancing the humidification effect.

[0042] This invention provides an air conditioner humidification device, an air conditioner, and a control method to improve user experience.

[0043] The following is combined Figures 1 to 7 The technical solution provided by this invention will be described in more detail below.

[0044] Example 1:

[0045] The air conditioner humidification device provided in this embodiment 1, such as Figure 1 , Figure 2 , Figure 5 As shown, an air supply duct 10 is provided inside an air conditioner 100. An evaporator 11, a deflecting ice plate 12, and a fan 13 are provided inside the air supply duct 10. The evaporator 11 is connected to the refrigeration system 110 of the air conditioner 100. The deflecting ice plate 12 is provided on one side of the evaporator 11. The evaporator 11 and the deflecting ice plate 12 divide the air supply duct 10 to form an S-shaped deflecting channel.

[0046] Specifically, the evaporator 11 and the air-guiding plate 12 are arranged in parallel. A first vent is formed between the first end of the air-guiding plate 12 and the air supply channel 10. A second vent is formed between the second end of the evaporator 11 and the air supply channel 10. A first channel is formed between the evaporator 11 and the air-guiding plate 12. The first vent, the first channel, and the second vent are connected to form an S-shaped air-guiding channel through which air flows around the evaporator 11.

[0047] The air conditioner humidification device provided in Embodiment 1 includes an air supply duct 10, within which an evaporator 11 is installed. The evaporator 11 is connected to the refrigeration system 110 of the air conditioner 100. The refrigeration system 110 can control the evaporator 11 to freeze through a four-way valve component. After freezing, the fan 13 operates to blow air into the room, carrying the condensed water on the evaporator 11 into the room, thereby achieving the humidification function. Using the above structure, there is no need to install a water tank and atomizing device, and no need to add extra water, which improves the user experience and also enables fresh air exchange. Furthermore, the evaporator 11 can be cleaned during rapid defrosting after freezing, achieving self-cleaning of the evaporator 11. In addition, the de-icing plate 12 is disposed on one side of the evaporator 11. The evaporator 11 and the de-icing plate 12 divide the air supply channel 10 into an S-shaped de-icing channel. By setting the de-icing channel, the contact area between the ambient temperature air delivered by the fan 13 and the ice on the evaporator 11 and the de-icing plate 12 can be increased, thereby improving the de-icing efficiency and the humidification effect.

[0048] It should be noted that the refrigeration system 110 of the air conditioner 100 is a refrigeration system in the prior art, which can be used for cooling or heating of the air conditioner 100 and has cooling or heating functions. In this embodiment, the refrigeration system 110 can be used to cool or heat the evaporator 11, thereby realizing the freezing and defrosting of the evaporator 11.

[0049] It is understood that in this embodiment, an air supply duct 10 is provided inside the air conditioner 100, and the evaporator 11, the deflecting ice plate 12, and the fan 13 are disposed within the air supply duct 10. In some optional embodiments, a separate device body can also be provided, which is mounted on the air conditioner 100, and the air supply duct 10 is provided within the device body, with the evaporator 11, the deflecting ice plate 12, and the fan 13 disposed within the air supply duct 10. The air supply duct 10 connects the outdoor and indoor environments, thereby completing the humidification function.

[0050] Furthermore, a heat-conducting column 14 is provided between the de-icing plate 12 and the evaporator 11. Both the heat-conducting column 14 and the de-icing plate 12 are made of aluminum. When the evaporator 11 freezes, it can conduct low temperature to the heat-conducting column 14 and the de-icing plate 12, so that water or ice will also condense on the surface of the heat-conducting column 14 and the de-icing plate 12. This allows the evaporator 11, the heat-conducting column 14, and the de-icing plate 12 to come into contact with the room temperature air delivered by the fan 13, improving the de-icing efficiency and humidification effect.

[0051] Furthermore, the heat-conducting columns 14 are arranged in rows between the fluidizing ice plate 12 and the evaporator 11, and adjacent rows of heat-conducting columns 14 are staggered.

[0052] In this further improvement, the heat-conducting columns 14 are arranged in rows between the flow-guiding ice plate 12 and the evaporator 11. Room temperature air can pass through the rows of heat-conducting columns 14 and condense water or freeze on the heat-conducting columns 14, further increasing the contact area between room temperature air and water and improving the humidification effect. Furthermore, by staggering the arrangement of two adjacent rows of heat-conducting columns 14, the circulation time of room temperature air in the flow channel and the contact area with water can be increased, further improving the humidification effect.

[0053] Preferably, an air inlet door 17 and an air outlet door 18 for opening and closing the air inlet door 15 and the air outlet door 16 of the air supply channel 10 are respectively provided.

[0054] In this further preferred embodiment, by providing an air inlet door 17 and an air outlet door 18, the air supply channel 10 can be closed or opened. When the humidification function is not needed, closing the air inlet 15 and the air outlet 16 can effectively protect the evaporator 11 and prevent dust and other foreign objects from entering the air supply channel 10.

[0055] Preferably, the fan 13 is located within the air supply channel 10 near the air outlet 16. Positioning the fan 13 near the air outlet 16 allows for more precise control of the air volume and effect, ensuring that the ambient temperature air brought in by the fan 13 has sufficient contact area with the evaporator 11, the heat-conducting column 14, and the de-icing plate 12, thus guaranteeing de-icing and humidification efficiency.

[0056] This embodiment 1 also provides an air conditioner 100, which includes the air conditioner humidification device as described above.

[0057] Example 2:

[0058] The air conditioner humidification device provided in this embodiment 2, such as Figures 3-5 As shown, an air supply duct 10 is provided inside an air conditioner 100. An evaporator 11, a deflecting ice plate 12, and a fan 13 are provided inside the air supply duct 10. The evaporator 11 is connected to the refrigeration system 110 of the air conditioner 100. Two deflecting ice plates 12 are provided, and the two deflecting ice plates 12 are provided on both sides of the evaporator 11. The evaporator 11 and the deflecting ice plates 12 are arranged in parallel, and the two deflecting ice plates 12 and the evaporator 11 form a U-shaped first channel. The first vent and the U-shaped first channel are connected by a second vent to form an S-shaped deflecting channel in which air flows around the evaporator 11.

[0059] The air conditioner humidification device provided in Embodiment 2 includes an air supply duct 10, within which an evaporator 11 is installed. The evaporator 11 is connected to the refrigeration system 110 of the air conditioner 100. The refrigeration system 110 can control the evaporator 11 to freeze through a four-way valve component. After freezing, the fan 13 operates to blow air into the room, carrying the condensed water on the evaporator 11 into the room, thereby achieving the humidification function. Using the above structure, there is no need to install a water tank and atomizing device, and no need to add extra water, which improves the user experience and also enables fresh air exchange. Furthermore, the evaporator 11 can be cleaned during rapid defrosting after freezing, achieving self-cleaning of the evaporator 11. In addition, the evaporator 11 and the ice-deflecting plate 12 are arranged in parallel, and the two sets of ice-deflecting plates 12 form a U-shaped first channel with the evaporator 11, which can increase the contact area between the room temperature air delivered by the fan 13 and the ice on the evaporator 11 and the ice-deflecting plate 12, thereby improving the ice-deflecting efficiency and humidification effect.

[0060] Furthermore, a heat-conducting column 14 is provided between the de-icing plate 12 and the evaporator 11. Both the heat-conducting column 14 and the de-icing plate 12 are made of aluminum. When the evaporator 11 freezes, it can conduct low temperature to the heat-conducting column 14 and the de-icing plate 12, so that water or ice will also condense on the surface of the heat-conducting column 14 and the de-icing plate 12. This allows the evaporator 11, the heat-conducting column 14, and the de-icing plate 12 to come into contact with the room temperature air delivered by the fan 13, improving the de-icing efficiency and humidification effect.

[0061] Furthermore, the heat-conducting columns 14 are arranged in rows between the fluidizing ice plate 12 and the evaporator 11, and adjacent rows of heat-conducting columns 14 are staggered.

[0062] In this further improvement, the heat-conducting columns 14 are arranged in rows between the flow-guiding ice plate 12 and the evaporator 11. Room temperature air can pass through the rows of heat-conducting columns 14 and condense water or freeze on the heat-conducting columns 14, further increasing the contact area between room temperature air and water and improving the humidification effect. Furthermore, by staggering the arrangement of two adjacent rows of heat-conducting columns 14, the circulation time of room temperature air in the flow channel and the contact area with water can be increased, further improving the humidification effect.

[0063] Preferably, an air inlet door 17 and an air outlet door 18 for opening and closing the air inlet door 15 and the air outlet door 16 of the air supply channel 10 are respectively provided.

[0064] In this further preferred embodiment, by providing an air inlet door 17 and an air outlet door 18, the air supply channel 10 can be closed or opened. When the humidification function is not needed, closing the air inlet 15 and the air outlet 16 can effectively protect the evaporator 11 and prevent dust and other foreign objects from entering the air supply channel 10.

[0065] Preferably, the fan 13 is located within the air supply channel 10 near the air outlet 16. Positioning the fan 13 near the air outlet 16 allows for more precise control of the air volume and effect, ensuring that the ambient temperature air brought in by the fan 13 has sufficient contact area with the evaporator 11, the heat-conducting column 14, and the de-icing plate 12, thus guaranteeing de-icing and humidification efficiency.

[0066] This embodiment 2 also provides an air conditioner 100, which includes the air conditioner humidification device as described above.

[0067] Example 3:

[0068] This embodiment 3 provides a control method, such as Figure 6 As shown, a humidification device for controlling the air conditioner as described above includes:

[0069] The system detects the indoor humidity level b. If the detected value b is less than the preset value a, the humidification mode is activated.

[0070] Activating the humidification mode includes: controlling the evaporator 11 to be in cooling mode, at which time the air inlet 15 is opened, the fan 13 of the air conditioner humidification device stops running, and the evaporator 11 begins to freeze;

[0071] Check if the evaporator 11 has finished freezing. If so, turn off the evaporator 11, open the air outlet 16, and start the fan 13 of the air conditioner humidification device to melt the ice on the evaporator 11 and humidify the room.

[0072] After the ice on the evaporator 11 melts, the evaporator 11 is switched to heating mode to quickly evaporate and vaporize the water on the evaporator 11.

[0073] Example 4:

[0074] This embodiment 4 provides a control method, such as Figure 6 As shown, a humidification device for controlling the air conditioner as described above includes:

[0075] Check if the air conditioner's humidifier has a self-cleaning function; if not, it will not work.

[0076] If so, the indoor humidity value b will be detected. If the detected value b is less than the preset value a, the humidification mode will be activated.

[0077] Activating the humidification mode includes: controlling the evaporator 11 to be in cooling mode, at which time the air inlet 15 is opened, the fan 13 of the air conditioner humidification device stops running, and the evaporator 11 begins to freeze;

[0078] Check if the evaporator 11 has finished freezing. If so, turn off the evaporator 11, open the air outlet 16, and start the fan 13 of the air conditioner humidification device to melt the ice on the evaporator 11 and humidify the room.

[0079] After the ice on the evaporator 11 melts, the evaporator 11 is switched to heating mode to quickly evaporate and vaporize the water on the evaporator 11.

[0080] Example 5:

[0081] This embodiment 5 provides a control method, such as Figure 7 As shown, a humidification device for controlling the air conditioner as described above includes:

[0082] Determine if the air conditioner's humidifier is self-cleaning; if not, activate the self-cleaning mode.

[0083] If so, the indoor humidity value b will be detected. If the detected value b is less than the preset value a, the humidification mode will be activated.

[0084] Activating the self-cleaning mode includes: controlling the evaporator 11 to be in cooling mode, at which time the air inlet 15 is open, the air outlet 16 is closed, the fan 13 of the air conditioner humidifier stops running, causing the evaporator 11 to begin to freeze;

[0085] If the evaporator 11 has completed icing, the system will quickly switch the evaporator 11 to heating mode to melt the ice quickly. The ice will then carry away the dust as it peels off the evaporator 11.

[0086] Activating the humidification mode includes: controlling the evaporator 11 to be in cooling mode, at which time the air inlet 15 is opened, the fan 13 of the air conditioner humidification device stops running, and the evaporator 11 begins to freeze;

[0087] Check if the evaporator 11 has finished freezing. If so, turn off the evaporator 11, open the air outlet 16, and start the fan 13 of the air conditioner humidification device to melt the ice on the evaporator 11 and humidify the room.

[0088] After the ice on the evaporator 11 melts, the evaporator 11 is switched to heating mode to quickly evaporate and vaporize the water on the evaporator 11.

[0089] Furthermore, it is determined whether the air conditioner humidifier is self-cleaning. If not, the self-cleaning mode is activated, including issuing a self-cleaning command after the air conditioner has been running for a preset time T1. After the air conditioner has been running for a preset time T1, the air conditioner humidifier can manually activate the self-cleaning mode to complete the self-cleaning of the evaporator 11.

[0090] Furthermore, it determines whether the air conditioner humidifier self-cleans; if not, it activates the self-cleaning mode. It also includes: if the air conditioner humidifier has not activated the self-cleaning mode after a preset running time T2, the air conditioner humidifier will automatically activate the self-cleaning mode.

[0091] In this further improved scheme, after the air conditioner humidifier has been running for a preset time T1, it issues a self-cleaning command. If the self-cleaning mode is not manually activated, and after the air conditioner has been running for a preset time T2, if the air conditioner humidifier detects that it has not yet activated the self-cleaning mode, then the air conditioner humidifier will automatically activate the self-cleaning mode. If the air conditioner humidifier has already activated the self-cleaning mode after the air conditioner has been running for a preset time T2, then the humidification mode will be activated.

[0092] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
