[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0033] The following is combined with Figures 1-12 The present invention describes a new air dehumidifier.

[0034] Embodiments of the present invention propose a fresh air dehumidifier, such as... Figure 1 , Figure 2 and Figure 12 As shown, the fresh air dehumidifier includes a housing 100 and an internal circulation guide plate component 190.

[0035] The outer casing 100 has a fresh air duct 103 and an internal circulation duct 104 arranged along a first direction. The first side of the outer casing 100 has a fresh air inlet 101 connected to the fresh air duct 103, and the second side of the outer casing 100 has an indoor air outlet 102 connected to the fresh air duct 103 and an indoor air inlet 107 connected to the internal circulation duct 104. The fresh air duct 103 is provided with a dehumidification module 300, a heating module 400, a humidification module 200 and an air supply module 500 arranged sequentially along the first direction, and the air supply module 500 is close to the indoor air outlet 102. The internal circulation guide plate component 190 is disposed between the first side of the internal circulation channel 104 and the first side of the fresh air channel 103. The internal circulation guide plate component 190 is used to connect and disconnect the internal circulation channel 104 and the fresh air channel 103.

[0036] It is understandable that the fresh air duct 103 is equipped with a dehumidification module 300, a heating module 400, a humidification module 200, and an air supply module 500, so that the fresh air dehumidifier can realize the functions of humidification, dehumidification, and fresh air supply.

[0037] Specifically, the air supply module 500 in the fresh air duct 103 can work independently to achieve the fresh air function; the air supply module 500 can be combined with the dehumidification module 300, the heating module 400, and the humidification module 200 to achieve fresh air + dehumidification function, fresh air + heating function, fresh air + humidification function, fresh air + dehumidification + heating function, and fresh air + heating + humidification function.

[0038] The new air dehumidifier provided by this invention has a fresh air channel 103 and an internal circulation channel 104 formed within the outer casing 100, and an internal circulation guide plate component 190 is provided between the fresh air channel 103 and the internal circulation channel 104. The internal circulation guide plate component 190 enables the connection and disconnection of the internal circulation channel 104 and the fresh air channel 103. When the outdoor environment is good, outdoor air is introduced into the room through the fresh air channel 103. When the outdoor environment is bad or the temperature is extreme, the indoor air can be introduced into the room again through the connection between the internal circulation channel 104 and the fresh air channel 103. Alternatively, the air introduced into the room by the fresh air inlet 101 can be regulated by the dehumidification module 300 and the heating module 400, effectively ensuring good indoor air quality and thus improving the user experience.

[0039] like Figures 1 to 5 ,as well as Figure 12 As shown, the internal circulation guide plate component 190 is disposed between the side of the internal circulation channel 104 away from the indoor air inlet 107 and the side of the fresh air channel 103 near the fresh air inlet 101.

[0040] Specifically, the outer casing 100 has a fresh air inlet 101 and an indoor air outlet 102 arranged opposite to each other. A fresh air duct 103 is formed between the fresh air inlet 101 and the indoor air outlet 102. Outdoor air enters the fresh air duct 103 through the fresh air inlet 101 and is discharged to the indoor space through the indoor air outlet 102 to achieve outdoor circulation. When the fresh air duct 103 and the internal circulation duct 104 are connected, indoor air enters the fresh air duct 103 through the indoor air inlet 107 and the internal circulation duct 104, and returns to the indoor space again through the indoor air outlet 102 to achieve indoor circulation.

[0041] Understandably, when the outdoor environment is harsh or the temperature is extreme, the internal circulation channel 104 and the fresh air channel 103 are connected. Indoor air is reintroduced into the room through the internal circulation channel 104 and the fresh air channel 103, which can effectively ensure good indoor air quality and thus improve the user experience.

[0042] In one embodiment of the present invention, such as Figure 1 As shown, the outer shell 100 is a rectangular shell structure. The first direction and the second direction are the length direction and the width direction of the outer shell 100, respectively. X represents the first direction and Y represents the second direction. The outer shell 100 is provided with a partition plate 180 arranged along the first direction to divide the interior of the outer shell 100 into an internal circulation channel 104 and a fresh air channel 103 arranged adjacent to each other along the second direction. A fresh air inlet 101 is provided on the first side of the outer shell 100, and an indoor air outlet 102 and an indoor air inlet 107 are provided on the second side of the outer shell 100. The internal circulation guide plate component 190 is located between the side of the fresh air channel 103 near the fresh air inlet 101 and the side of the internal circulation channel 104 away from the indoor air inlet 107.

[0043] It is understandable that when the fresh air duct 103 and the internal circulation duct 104 are connected, indoor air enters the fresh air duct 103 through the indoor air inlet 107 and the internal circulation duct 104, and returns to the indoor space through the indoor air outlet 102 to achieve indoor circulation; when the fresh air duct 103 and the internal circulation duct 104 are disconnected, outdoor air enters the fresh air duct 103 through the fresh air inlet 101, and is discharged to the indoor space through the indoor air outlet 102 to achieve outdoor circulation.

[0044] In one embodiment of the present invention, such as Figures 2 to 4 As shown, the fresh air duct 103 is provided with an air inlet side plate 110 and an air outlet side plate 120 arranged at intervals along a first direction. The air inlet side plate 110 is close to the fresh air inlet 101. The air inlet side plate 110, the air outlet side plate 120 and the inner wall of the outer shell 100 form a first mounting cavity 105, and the humidification module 200 is disposed in the first mounting cavity 105. The side of the air outlet side plate 120 away from the air inlet side plate 110 and the inner wall of the outer shell 100 form a second mounting cavity 106, and the air supply module 500 is disposed in the second mounting cavity 106. A third mounting cavity 108 is formed between the fresh air inlet 101 and the first mounting cavity 105.

[0045] In one embodiment of the present invention, such as Figure 12 As shown, the air inlet side panel 110 is provided with a first inlet 111, and the air outlet side panel 120 is provided with a first outlet 121; the fresh air inlet 101, the first inlet 111, the humidification module 200, the air supply module 500 and the indoor air outlet 102 are arranged in sequence along the first direction.

[0046] For example, the air inlet side panel 110 has a first inlet 111 in the middle, the air outlet side panel 120 has a first outlet 121 in the middle, the humidification module 200 is located between the first inlet 111 and the first outlet 121, the fresh air inlet 101 corresponds to the first inlet 111, and the air supply module 500 corresponds to the first outlet 121.

[0047] In another embodiment of the invention, such as Figures 1 to 3 As shown, the air inlet side panel 110 is provided with a first inlet 111 and a second inlet 112 arranged at intervals. The second inlet 112 is provided with a first guide plate component 150 that can be opened or closed. The air outlet side panel 120 is provided with a first outlet 121 and a second outlet 122 arranged at intervals. The first inlet 111, the humidification module 200 and the first inlet 111 are arranged sequentially along the first direction. The second inlet 112, the second outlet 122 and the air supply module 500 are arranged sequentially along the first direction. The second inlet 112 and the humidification module 200 are arranged in a staggered manner. It should be noted that the air outlet side panel 120 can also be provided with an elongated hole arranged along the second direction, with one side of the elongated hole serving as the first outlet 121 and the other side of the elongated hole serving as the second outlet 122.

[0048] It is understood that the outer casing 100 has a fresh air inlet 101 and an indoor air outlet 102 arranged opposite to each other, and a fresh air channel 103 is formed between the fresh air inlet 101 and the indoor air outlet 102. Outdoor air enters the fresh air channel 103 through the fresh air inlet 101 and is discharged to the indoor space through the indoor air outlet 102. The first mounting cavity 105 has a first inlet 111 and a second inlet 112 arranged at intervals along the second direction on the side wall near the fresh air inlet 101 (i.e., the inlet side of the humidification module 200). The first mounting cavity 105 has a first outlet 121 and a second outlet 122 arranged at intervals along the second direction on the side wall near the indoor air outlet 102 (i.e., the outlet side of the humidification module 200). The first inlet 111, the humidification module 200 and the first outlet 121 are arranged opposite each other along the first direction. The second inlet 112 and the second outlet 122 are arranged opposite each other along the first direction. The humidification module 200 and the second outlet 122 are arranged in a staggered manner along the second direction. Thus, the first inlet 111, the humidification module 200 and the first outlet 121 form a humidification channel, and the second inlet 112 and the second outlet 122 form an air channel. A first guide plate component 150 that can be opened or closed is provided at the second inlet 112 to realize the connection and disconnection of the air channel.

[0049] Specifically, when the first guide plate component 150 opens the second inlet 112, outdoor air enters through the fresh air inlet 101 and is divided into two paths. One path enters the air supply module 500 of the second mounting cavity 106 through the first inlet 111, the humidification module 200, and the first outlet 121, while the other path enters the air supply module 500 of the second mounting cavity 106 through the second inlet 112 and the second outlet 122. When the first guide plate component 150 closes the second inlet 112, outdoor air enters through the fresh air inlet 101 and all of it enters the air supply module 500 of the second mounting cavity 106 through the first inlet 111, the humidification module 200, and the first outlet 121.

[0050] It is understandable that by opening the second inlet 112 through the first guide plate component 150, the outdoor air introduced by the fresh air inlet 101 enters the first installation cavity 105 through the second inlet 112 without passing through the humidification module 200, thereby reducing the wind resistance caused by the air passing through the humidification module 200, effectively reducing the workload of the air supply module 500, and thus reducing the energy consumption during the operation of the fresh air humidifier.

[0051] The fresh air humidifier provided in this embodiment of the invention includes a humidification module 200 installed in the fresh air channel 103. A first inlet 111 and a second inlet 112 are formed on the inlet side of the humidification module 200, with the first inlet 111 corresponding to the humidification module 200 and the second inlet 112 offset from it. A first outlet 121 and a second outlet 122 are formed on the outlet side of the humidification module 200, with the first outlet 121 corresponding to the humidification module 200 and the second outlet 122 offset from it. Thus, the second inlet 112 can be opened by the first guide plate component 150, allowing outdoor air introduced by the fresh air inlet 101 to enter the first mounting cavity 105 through the second inlet 112 without passing through the humidification module 200. This reduces the wind resistance caused by the air passing through the humidification module 200, effectively reducing the workload of the air supply module 500, and consequently reducing the energy consumption during the operation of the fresh air humidifier.

[0052] Optionally, the fresh air inlet 101, the second inlet 112, the second outlet 122, the air supply module 500, and the indoor air outlet 102 are arranged sequentially along the first direction.

[0053] It is understandable that, with the fresh air inlet 101 and the second inlet 112 arranged opposite each other along the first direction, when the first guide plate component 150 opens the second inlet 112, most of the outdoor air introduced by the fresh air inlet 101 flows into the second inlet 112, further reducing the workload of the air supply module 500. It should be noted that, with the fresh air inlet 101 and the second inlet 112 arranged opposite each other, the fresh air inlet 101 and the first inlet 111 are offset along the second direction, and a small amount of outdoor air introduced by the fresh air inlet 101 enters the humidification module 200 for humidification via the first inlet 111.

[0054] In one embodiment of the present invention, such as Figure 3 As shown, the first guide plate component 150 includes a first air plate drive and a first air guide plate. The first air plate drive is located at the second inlet 112 of the air inlet side plate 110. The first air guide plate is installed on the first air plate drive. The first air plate drive drives the first air guide plate to open or close the second inlet 112.

[0055] It is understandable that the first air deflector is driven by a drive motor, which drives the first air deflector to switch between a first open position and a first closed position; in the first closed position, the first air deflector covers the second inlet 112 to close the second inlet 112; in the first open position, the first air deflector opens away from the second inlet 112 to open the second inlet 112.

[0056] In this embodiment, the first air deflector is driven by a rotary motor, which drives the first air guide plate to swing to open or close the second inlet 112.

[0057] Furthermore, the surface of the first air guide plate is provided with a sealing element to improve the sealing performance of the first air guide plate when closing the second inlet 112; at the same time, it avoids damage when the first air guide plate is in rigid contact with the second inlet 112 of the air inlet side plate 110.

[0058] In one embodiment of the present invention, such as Figures 1 to 3 As shown, an internal circulation channel 104 is also formed inside the outer casing 100. The internal circulation channel 104 has an indoor air inlet 107. The indoor air outlet 102 and the indoor air inlet 107 are located on the same side of the outer casing 100. An internal circulation guide plate component 190 is provided between the internal circulation channel 104 and the fresh air channel 103. The internal circulation guide plate component 190 is used to connect and disconnect the fresh air channel 103 and the internal circulation channel 104.

[0059] In this embodiment, the internal circulation guide plate component 190 is disposed between the third mounting cavity 108 and the internal circulation channel 104. The internal circulation guide plate component 190 is used to connect and disconnect the third mounting cavity 108 and the internal circulation channel 104. Specifically, the partition plate 180 has an internal circulation vent 181 at a position corresponding to the third mounting cavity 108. The internal circulation guide plate component 190 is disposed at the position of the internal circulation vent 181 on the partition plate 180. The internal circulation guide plate component 190 is used to open or close the internal circulation vent 181 to realize the connection and disconnection between the third mounting cavity 108 and the internal circulation channel 104.

[0060] Optional, such as Figure 4 As shown, the internal circulation guide plate component 190 includes an internal circulation guide plate 191 and an internal circulation air plate drive component 192. The internal circulation air plate drive component 192 is disposed at the internal circulation air outlet 181 of the partition plate 180. The internal circulation guide plate 191 is installed on the internal circulation air plate drive component 192. The internal circulation air plate drive component 192 drives the internal circulation guide plate 191 to open or close the internal circulation air outlet 181.

[0061] Optionally, the internal circulation air vane drive 192 drives the internal circulation air guide vane 191 to switch between a first position, a second position, and a third position; in the first position, the internal circulation air guide vane 191 closes the internal circulation air outlet 181 and the fresh air damper opens the fresh air inlet 101; in the second position, the internal circulation air guide vane 191 opens the internal circulation air outlet 181 and the fresh air damper closes the fresh air inlet 101; in the third position, the internal circulation air guide vane 191 opens at least part of the internal circulation air outlet 181 and the fresh air damper opens at least part of the fresh air inlet 101.

[0062] Understandably, when the current indoor oxygen content is greater than the first preset oxygen content, the indoor space has sufficient oxygen, and the fresh air inlet 101 can be closed while the fresh air duct 103 and the internal circulation duct 104 are connected to allow for indoor circulation. When the current outdoor oxygen content is greater than the second preset oxygen content, the outdoor space has sufficient oxygen, and the fresh air inlet 101 can be opened while the fresh air duct 103 and the internal circulation duct 104 are disconnected to allow for outdoor circulation. When both the current indoor oxygen content and the current outdoor oxygen content are greater than the second preset oxygen content, the internal circulation guide vane 191 opens at least part of the internal circulation air outlet 181, and the fresh air damper opens at least part of the fresh air inlet 101 to allow for simultaneous outdoor and indoor circulation. It should be noted that when the outdoor environment is good, outdoor circulation can be performed, or both outdoor and indoor circulation can be performed simultaneously.

[0063] Optionally, the internal circulation guide plate component 190 can adopt the same structure as the first guide plate component 150. The internal circulation air plate drive component 192 drives the internal circulation air guide plate 191 to swing. In the first position, the internal circulation air guide plate 191 covers the internal circulation air outlet 181 of the partition plate 180, and the outdoor circulation is opened. In the second position, the internal circulation air guide plate 191 opens the internal circulation air outlet 181, and the internal circulation air guide plate 191 and the partition plate 180 can form a 90° angle, and the indoor circulation is opened. In the third position, the internal circulation air guide plate 191 and the partition plate 180 can form a 45° angle, and the indoor circulation and outdoor circulation are opened simultaneously.

[0064] In one embodiment of the present invention, such as Figures 2 to 4As shown, a first partition 130 is provided in the third mounting cavity 108 to divide the third mounting cavity 108 into a first air duct 1061 and a second air duct 1062. The first air duct 1061 is connected to the fresh air inlet 101. A third inlet 131 is opened at the position corresponding to the first inlet 111 on the first partition 130. A fourth inlet 132 is opened at the position corresponding to the second inlet 112 on the first partition 130. The fourth inlet 132 is provided with a second guide plate component 160 that can be opened or closed. A second partition 140 is provided in the first air duct 1061. One end of the second partition 140 is connected between the third inlet 131 and the fourth inlet 132, and the other end of the second partition 140 is connected to the outer shell 100.

[0065] It is understandable that the internal circulation guide plate component 190 corresponds to the first air duct 1061, and the internal circulation guide plate component 190 realizes the connection and disconnection between the first air duct 1061 and the internal circulation channel 104; when the first air duct 1061 is connected to the internal circulation channel 104, in order to avoid the indoor air entering the first air duct 1061 from affecting the outdoor air of the fresh air inlet 101, a second baffle 140 is provided in the first air duct 1061.

[0066] Furthermore, the second partition 140 is provided with a fifth inlet 141, and the fifth inlet 141 is provided with a third guide plate component 170 that can be opened or closed.

[0067] Understandably, during indoor circulation, the internal circulation guide plate component 190 opens the internal circulation vent 181, and the third guide plate component 170 closes the fifth inlet 141. Indoor air enters the internal circulation channel 104 through the indoor air inlet 107, enters the first air duct 1061 through the internal circulation vent 181, and enters the second air duct 1062 through the third inlet 131. Preferably, when simultaneous indoor and outdoor circulation is required, the internal circulation guide plate component 190 opens the internal circulation vent 181, the third guide plate component 170 closes the fifth inlet 141, and the second guide plate component 160 opens the fourth inlet 132.

[0068] During outdoor circulation, the internal circulation guide plate component 190 closes the internal circulation vent 181, and the fourth inlet 132 and the fifth inlet 141 can be opened or closed as needed. When the second guide plate component 160 opens the fourth inlet 132, outdoor air enters the second air duct 1062 through the fresh air inlet 101 and the fourth inlet 132. When the third guide plate component 170 opens the fifth inlet 141, outdoor air enters the second air duct 1062 through the fresh air inlet 101, the fifth inlet 141, and the third inlet 131. It should be noted that during outdoor circulation, the fourth inlet 132 and the fifth inlet 141 can also be opened simultaneously. Preferably, when the second inlet 112 is open, the fourth inlet 132 is opened and the fifth inlet 141 is closed; when the second inlet 112 is closed, the fifth inlet 141 is opened and the fourth inlet 132 is closed.

[0069] When indoor and outdoor circulation are carried out simultaneously, the internal circulation guide plate component 190 opens the internal circulation vent 181, the third guide plate component 170 closes the fifth inlet 141, and the second guide plate component 160 opens the fourth inlet 132.

[0070] like Figures 6 to 10 As shown, the humidification module 200 includes a water storage tank 210, a protective shell 220, and a spray component 280. The protective shell 220 is located outside the water storage tank 210 and is connected to the water storage tank 210. An inner air inlet and an inner air outlet 222 are provided on the shell of the protective shell 220. The water inlet of the spray component 280 is connected to the water storage tank 210, and the water outlet of the spray component 280 is located inside the protective shell 220, which is used to spray water mist onto the air flowing from the inner air inlet to the inner air outlet 222.

[0071] In this embodiment, a spray component 280 is provided to directly spray water mist onto the air flowing from the inner air inlet to the inner air outlet 222. This allows the air to fully contact the water mist as it flows through the protective shell 220, achieving a rapid and efficient humidification effect. Compared to traditional evaporation or steam humidification methods, this method can change air humidity more quickly, meeting the need for rapid humidification. The tight fit between the water storage tank 210 and the protective shell 220 makes the entire humidification module 200 compact and space-saving. Simultaneously, the design of the protective shell 220 effectively protects the spray component 280, preventing interference and damage from the external environment, thus improving the durability and service life of the equipment. The water outlet of the spray component 280 is located inside the protective shell 220, effectively preventing water mist from directly contacting users or electrical equipment, thereby improving safety during use.

[0072] like Figure 6 and Figure 7As shown, in some embodiments, the spray component 280 includes a spray pump 281, a first spray pipe 282, and a first nozzle; the spray pump 281 is installed in a water storage tank 210; the outlet end of the spray pump 281 is connected to the inlet end of the first spray pipe 282, for pumping water from the water storage tank 210 into the first spray pipe 282; the first nozzle is located inside the protective housing 220; the first nozzle is connected to the outlet end of the first spray pipe 282, for spraying water mist onto the air flowing from the inner air inlet to the inner air outlet 222.

[0073] In this embodiment, by setting a spray pump 281, the water spray pressure of the first nozzle can be adjusted, thereby regulating the amount of air humidification. Specifically, when the spray pump 281 operates at a high setting, the pressure of the first nozzle is greater, resulting in a finer water mist and increased air humidity. When the spray pump 281 operates at a low setting, the pressure of the first nozzle is lower, resulting in less water mist and reduced air humidity.

[0074] Preferably, the spray component 280 includes a plurality of first nozzles; the plurality of first nozzles are arranged at intervals along a second direction and are all connected to the first spray pipe 282. The plurality of first nozzles can improve the uniformity of water mist, increase the contact area with air, and increase the humidification speed.

[0075] In some embodiments, the fresh air dehumidifier also includes a control component; the control component is electrically connected to the spray pump 281; the control component controls the operation of the spray pump 281 according to the air dryness, thereby adjusting the spray pump 281's speed. Specifically, when the air humidity is lower than the set humidity, the control component controls the spray pump 281 to operate in a high-speed pumping mode. When the air humidity is not lower than the set humidity, the control component controls the spray pump 281 to operate in a low-speed pumping mode.

[0076] Preferably, the spray pump 281 is a self-priming pump.

[0077] In some other embodiments, the humidification module 200 includes a first water inlet pipe and a first regulating valve; the inlet end of the first water inlet pipe is connected to a water source, and the outlet end is connected to a water storage tank 210, for introducing water into the water storage tank 210; the first regulating valve is installed on the first water inlet pipe for adjusting the water flow rate of the first water inlet pipe.

[0078] In this embodiment, by setting a first regulating valve on the first water inlet pipe, the water inlet volume of the water storage tank 210 can be adjusted by adjusting the opening degree of the first regulating valve.

[0079] Preferably, the first regulating valve is an electromagnetic regulating valve.

[0080] Furthermore, the spray component 280 includes a second spray pipe, a second regulating valve, and a second nozzle. The water inlet end of the second spray pipe is connected to the water inlet of the first regulating valve through a first water inlet pipe; the second regulating valve is disposed in the second spray pipe and is used to adjust the water flow rate of the second spray pipe; the second nozzle is located inside the protective housing 220; the second nozzle is connected to the water outlet end of the second spray pipe and is used to spray water mist onto the air flowing from the inner air inlet to the inner air outlet 222.

[0081] In this embodiment, the water inlet is connected to the water inlet of the first regulating valve through the first water inlet pipe. Part of the water entering from the water inlet of the first water inlet pipe flows into the water storage tank 210 through the first regulating valve, and the other part flows to the second spray pipe. This avoids the need to install a spray pump 281, further reducing costs.

[0082] Preferably, the spray component 280 includes a plurality of second nozzles; the plurality of second nozzles are arranged at intervals along a second direction and are all connected to a second spray pipe. The plurality of second nozzles can improve the uniformity of the water mist, increase the contact area with air, and increase the humidification speed.

[0083] In one embodiment of the present invention, such as Figure 2 As shown, the heating module 400 is located at the first inlet 111.

[0084] It is understandable that by installing a humidification module 200 in the fresh air duct 103 and arranging a heating module 400 on the inlet side of the humidification module 200, the air temperature in the fresh air duct 103 can be adjusted by the heating module 400 to reduce the difference between the air temperature at the indoor air outlet 102 and the indoor ambient temperature, thereby reducing indoor temperature fluctuations and helping to improve the user experience.

[0085] Furthermore, the heating module 400 is located on the side of the air outlet side panel 120 near the fresh air inlet 101. A water storage tank 210 located below the heating module 400 is provided in the second air duct 1062. When the heating module 400 is working, the heat generated can be directly transferred to the water in the water storage tank 210 below, accelerating the water evaporation process, thereby increasing the relative humidity of the air and thus improving the humidification efficiency.

[0086] Specifically, the heating module 400 is installed on the side wall of the air inlet panel, opposite to the inner air inlet, and is used to heat the air entering the inner air inlet. By setting the heating module 400 at the position corresponding to the inner air inlet, the air can be heated to adjust the air temperature.

[0087] In this embodiment, the control component is electrically connected to the heating module 400. The control component controls the heating module 400 to start or stop based on the indoor air temperature to adjust the indoor air temperature. Specifically, when the indoor air temperature is lower than the set temperature, the control component controls the heating module 400 to start. When the indoor temperature is not lower than the set temperature, the control component controls the heating module 400 to stop.

[0088] Preferably, the heating module 400 is an electric heater, and the start-up or shutdown of the electric heater is controlled by the current switching.

[0089] Optionally, the housing 100 has a drainage groove located below the heating module 400. The drainage groove 1010 is located outside the protective housing 220 and close to the inner air inlet. The drainage groove 1010 is connected to the water storage tank 210. The drainage groove 1010 has a drain outlet to facilitate the drainage of water in the drainage groove 1010.

[0090] In this embodiment, a drainage trough 1010 is provided. The drainage trough 1010 has a certain volume, which can temporarily store water and cool surrounding components. By placing the drainage trough 1010 on the outside of the water storage tank 210 and near the inner air inlet, air must first pass over the drainage trough 1010 before entering the inner air inlet. At this time, the drainage trough 1010 absorbs heat from surrounding components and partially vaporizes. The air then carries away the vaporized water molecules, achieving primary humidification of the air.

[0091] Furthermore, the side wall of the first mounting cavity 105 is provided with an overflow port that connects the drainage channel 1010 and the water storage tank 210.

[0092] Specifically, an overflow outlet is provided on the air inlet side panel 110. The overflow outlet has a certain height. When the water level in the water storage tank 210 reaches the preset height, the water in the water storage tank 210 is discharged to the drainage tank 1010 through the overflow outlet.

[0093] In this embodiment, the drainage trough 1010 is located on one side of the inner air inlet of the protective shell 220, and the heating module 400 is located on the upper part of one side of the drainage trough 1010. When the heating module 400 is heating, it can heat the water in the drainage trough 1010, thus achieving primary humidification of the air. The air that has undergone primary humidification enters the protective shell 220 through the inner air inlet, and performs secondary humidification on the wet film humidification component 230, which can improve the speed of air humidification.

[0094] Furthermore, the humidification module 200 also includes a second water level detection component 290 and an alarm component. The second water level detection component 290 is installed in the drain tank 1010 and is used to detect the actual water volume in the drain tank 1010. The control component is electrically connected to the second water level detection component 290 and the alarm component. The control component is used to output an alarm control command when the actual water volume exceeds the upper limit, so as to control the alarm component to sound an alarm. This design can prevent the actual water volume in the drain tank 1010 from exceeding the upper limit and prevent water overflow. By setting an alarm device, the user can be reminded to drain the water in the drain tank 1010 in time.

[0095] In one embodiment of the present invention, a dehumidification module 300 is disposed in a third mounting cavity 108. When the air humidity is too high, the dehumidification module 300 dehumidifies the air to avoid excessive indoor air humidity.

[0096] Optionally, the dehumidification module 300 is disposed in the second air duct 1062. The dehumidification module 300 includes an evaporator and an evaporation bracket. The evaporator is installed in the outer casing 100 through the evaporation bracket. The evaporator can be connected to the compressor to achieve heat exchange with the air, so as to cool the air or dehumidify it by evaporation.

[0097] It is understandable that the evaporator is a microchannel heat exchanger, and the refrigerant is transported within the heat exchange tubes of the microchannel heat exchanger. Microchannel heat exchangers have high heat exchange efficiency, ensuring effective dehumidification of the air.

[0098] like Figures 6 to 10 As shown, the humidification module 200 further includes a wet film humidification component 230; the wet film humidification component 230 is rotatably mounted on the protective shell 220 around the second direction; the wet film humidification component 230 is located between the inner air inlet and the inner air outlet 222, and is used to absorb water in the protective shell 220 to humidify the air flowing from the inner air inlet to the inner air outlet 222.

[0099] In this embodiment, a wet film humidifying component 230 that can rotate around a second direction is provided inside the protective shell 220. The wet film humidifying component 230 is used to absorb water inside the protective shell 220. The humidification level of the air can be adjusted by adjusting the rotation speed of the wet film humidifying component 230. This solves the problems of complex humidification control process and inability to adjust humidification level in existing fresh air dehumidifiers.

[0100] In addition, the wet film humidification component 230 in this embodiment can also cooperate with the spray component 280 to adapt to different humidification needs, thereby improving the overall user experience of the device.

[0101] It should be noted that the wet film humidification component 230 includes a wet film material layer. This wet film material layer is existing technology and can be purchased. Specifically, the wet film material layer is prepared from a wet film material. This wet film material, also known as "Cydike" material, is the core of the wet film humidifier. It contains a slow-release antibacterial agent and is made from plant fibers as the base material. Through resin treatment with special components, it is sintered to form a corrugated, cross-overlapping polymer composite material. It possesses advantages such as strong water absorption, excellent self-cleaning ability, non-toxicity, acid and alkali resistance, mildew resistance, and flame retardancy. The unique structure of the wet film provides the maximum contact area between air and its surface, with each square meter of membrane providing 500-600 m² of humidification. 2 The contact area is large, and the membrane flow channel is inclined at 45 degrees. When hot, dry air passes through the wet membrane, the moisture absorbs the heat from the air and vaporizes, thus humidifying the air. During this humidification process, the air humidity increases and the temperature decreases, but the enthalpy of the air remains unchanged.

[0102] like Figures 8 to 10 As shown, the wet film humidification component 230 further includes a wet film rotation assembly 231 and a humidification drive assembly 232; the wet film rotation assembly 231 is located between the inner air inlet and the inner air outlet 222 and is used to absorb water in the protective shell 220; the humidification drive assembly 232 is located between the water storage tank 210 and the wet film rotation assembly 231 and is installed on the protective shell 220; the humidification drive assembly 232 is connected to the wet film rotation assembly 231 and is used to drive the wet film rotation assembly 231 to rotate around the second direction.

[0103] In this embodiment, the rotational speed of the wet film rotation component 231 can be adjusted by setting the humidification drive component 232, thereby adjusting the humidification level. For example, when it is necessary to reduce the amount of humidification of the air, the wet film rotation component 231 can be driven to rotate slowly by the humidification drive component 232. When it is necessary to increase the amount of humidification of the air, the wet film rotation component 231 can be driven to rotate quickly by the humidification drive component 232.

[0104] like Figure 8 As shown, specifically, to avoid water affecting the service life of the humidification drive component 232, a first installation space and a second installation space are formed inside the protective shell 220; the first installation space is located between the water storage tank 210 in the second installation space; the inner air inlet and the inner air outlet 222 are both connected to the second installation space and are arranged opposite to each other; the humidification drive component 232 is installed in the first installation space, and the wet film rotation component 231 is installed in the second installation space; the first installation space has a connecting flow channel, which is used to connect the water storage tank 210 and the second installation space.

[0105] Furthermore, the humidification drive assembly 232 includes a humidification drive component; the humidification drive component is mounted in the first mounting space, and the rotating shaft of the humidification drive component extends to the second mounting space and connects to the wet film rotation assembly 231. The humidification drive component directly drives the wet film rotation assembly 231 to rotate about a second direction. This design is beneficial for the miniaturization of the device.

[0106] Preferably, the humidification drive component can be a motor or a rotary cylinder, etc.

[0107] Furthermore, the humidification drive assembly 232 also includes a speed-changing gear set; one end of the speed-changing gear set is connected to the motor, and the other end is connected to the wet film rotation assembly 231. The motor drives the wet film rotation assembly 231 to rotate through the speed-changing gear set. By setting the speed-changing gear set, the motor speed can be adjusted, which can expand the range of motor selection.

[0108] Preferably, the gear set can be a reduction gear or an acceleration gear.

[0109] like Figures 8 to 10 As shown, the wet film rotating assembly 231 further includes a first humidification mounting flange 2311, a second humidification mounting flange 2312, and a wet film rotating component 2313; the first humidification mounting flange 2311 and the second humidification mounting flange 2312 are arranged at intervals along a second direction; the first humidification mounting flange 2311 is rotatably engaged with the humidification drive component around the second direction; the second humidification mounting flange 2312 is rotatably engaged with the protective shell 220 around the second direction; the two ends of the wet film rotating component 2313 are respectively connected to the first humidification mounting flange 2311 and the second humidification mounting flange 2312.

[0110] In this embodiment, the wet film rotating component 2313 is installed on the humidification drive assembly 232 and the protective shell 220 through the first humidification mounting flange 2311 and the second humidification mounting flange 2312, which can improve the rotational stability of the wet film rotating component 2313 and increase its service life.

[0111] Understandably, a wet film material layer is mounted on the outer surface of the wet film rotating component 2313.

[0112] For example, the wet film rotating component 2313 includes a rotating cylinder and a wet film material layer; both ends of the rotating cylinder are connected to the first humidification mounting flange 2311 and the second humidification mounting flange 2312 respectively, and the outer surface of the rotating cylinder is covered with a wet film material layer. In addition, in order to reduce air resistance, the wet film rotating component 2313 has multiple vent holes, which are arranged at intervals along the second direction. Air entering from the inner air inlet flows through the vent holes to the inner air outlet 222.

[0113] like Figure 8 and Figure 9As shown, exemplarily, the wet film rotating component 2313 includes multiple wet film connecting rings 2315 and multiple wet film connecting rods 2316; the multiple wet film connecting rings 2315 are spaced apart along a second direction; the multiple wet film connecting rods 2316 are spaced apart circumferentially around the wet film connecting rings 2315; the wet film connecting rods 2316 are connected to the wet film connecting rings 2315. The two ends of the wet film connecting rods 2316 are respectively connected to the first humidification mounting flange 2311 and the second humidification mounting flange 2312. This design reduces the air resistance of the wet film rotating component 2313, ensuring that air entering the second installation space from the inner air inlet can quickly flow out of the second installation space from the inner air outlet 222 after passing through the wet film rotating component 2313. Additionally, it increases the contact area between the air and the wet film rotating component 2313, improving the air humidification speed.

[0114] like Figure 8 He Ru Figure 10 As shown, the wet film rotating assembly 231 further includes a protective frame 2314; the protective frame 2314 is sleeved on the outside of the wet film rotating component 2313, and its two ends are respectively connected to the first humidification mounting flange 2311 and the second humidification mounting flange 2312. By providing the protective frame 2314, the wet film rotating component 2313 can be protected.

[0115] Preferably, the outer surface of the protective frame 2314 is covered with a wet film material layer, which can further increase the contact area between air and water and improve the humidification speed.

[0116] like Figure 10 As shown, specifically, the protective frame 2314 includes multiple crossbeams 2317 and multiple reinforcing ribs 2318; the multiple crossbeams 2317 are arranged circumferentially along the wet film connecting ring 2315, and the two ends of the crossbeams 2317 are respectively connected to the first humidification mounting flange 2311 and the second humidification mounting flange 2312. Reinforcing ribs 2318 are provided between adjacent crossbeams to improve the strength of the protective frame 2314.

[0117] Preferably, the surfaces of the crossbeam 2317 and the reinforcing rib 2318 are provided with a wet film material layer.

[0118] Preferably, the reinforcing rib 2318 has a circular ring structure, and multiple crossbeams 2317 are arranged circumferentially around the circular reinforcing rib 2318.

[0119] like Figures 6 to 10As shown, in some embodiments, the humidification module 200 further includes a first water level detection component 240 and a water volume adjustment component 250; the first water level detection component 240 is located in the water storage tank 210 and is used to detect the actual water volume in the water storage tank 210; the water volume adjustment component 250 is installed in the water storage tank 210 and is used to adjust the actual water volume in the water storage tank 210 so that the actual water volume is not less than a first water volume threshold and not greater than a second water volume threshold; the first water volume threshold is less than the second water volume threshold.

[0120] In this embodiment, this design ensures that the actual water volume in the water storage tank 210 is maintained within a certain range. This avoids both insufficient water volume, ensuring the humidification effect, and excessive water volume, preventing water waste.

[0121] Furthermore, the water volume regulating component 250 includes an inlet component 251 and a drain component 252; the inlet component 251 has a high-level water filling mode and a low-level water filling mode; the drain component 252 has an open state and a closed state; when the actual water volume is less than a first water volume threshold, the inlet component 251 operates in the high-level water filling mode; when the actual water volume is within the water volume balance threshold range, the inlet component 251 operates in the low-level water filling mode; when the actual water volume is greater than a second water volume threshold, the drain component 252 switches from the closed state to the open state to drain the water in the water storage tank 210; the minimum water volume balance threshold of the water volume balance threshold range is greater than the first water volume threshold, and the maximum water volume balance threshold of the water volume balance threshold range is less than the second water volume threshold.

[0122] In this embodiment, this design allows for the adjustment of the water volume in the water storage tank 210. Specifically, the water inlet and outlet rates can be adjusted based on the actual water volume in the water storage tank 210; the water inlet rate can also be adjusted based on the water consumption of the humidifier to prevent excessive water inlet and the actual water volume from exceeding the second water volume threshold, thereby reducing the number of drainage cycles and lowering the total drainage volume.

[0123] It should be noted that when the actual water volume is within the water balance threshold range, it means that the actual water volume has reached a balance between water intake and humidification. At this time, the water intake component 251 can operate in a low-level water intake mode to achieve a balance between humidification and water supply.

[0124] Furthermore, the control unit is electrically connected to the wet film humidification unit 230, the first water level detection unit 240, and the water volume adjustment unit 250.

[0125] The control unit can adjust the rotation speed of the humidification unit 230 according to the air dryness, thereby regulating the humidification output. Specifically, when the actual indoor humidity is lower than the set humidity, the control unit switches the humidification unit 230 to high-level humidification, at which point the humidification unit 230 rotates rapidly. When the actual indoor humidity reaches the set humidity, the control unit switches the humidification unit 230 to low-level humidification, at which point the rotation speed of the humidification unit 230 decreases.

[0126] The control unit receives the actual water volume from the first water level detection unit 240. The control unit compares the actual water volume with the first water volume threshold, the second quantity threshold, and the water balance threshold range. Specifically, when the actual water volume is less than the first water volume threshold, the control unit controls the water inlet component 251 to operate in a high-level water filling mode. When the actual water volume is within the water balance threshold range, the control unit controls the water inlet component 251 to operate in a low-level water filling mode. When the actual water volume is greater than the second water volume threshold, the control unit controls the drainage component 252 to switch from the closed state to the open state to drain the water in the water storage tank 210.

[0127] Furthermore, the first water level detection component 240 includes a guide rod, a float, and a water level sensor; the float is mounted on the guide rod; the water level sensor is mounted on the float, and the float moves up and down along the guide rod as the water level rises and falls. The water level sensor is used to detect the water level in the water storage tank 210 and transmits an electrical signal representing the water level to the control component. After receiving the electrical signal, the control component calculates the actual water volume in the water storage tank 210, and then compares the actual water volume with a first water volume threshold, a second water volume threshold, and a water balance threshold range; finally, it outputs different control commands based on the comparison results.

[0128] Preferably, the second water level detection component 290 has the same structure as the first water level detection component 240.

[0129] like Figure 6 and Figure 7 As shown, the water inlet assembly 251 includes a water inlet pipe 2511 and a water inlet solenoid valve 2512; one end of the water inlet pipe 2511 is located outside the water storage tank 210 and is connected to the water source; the other end is located inside the water storage tank 210. The water inlet solenoid valve 2512 is installed on the water inlet pipe 2511 and is used to regulate the water inlet flow rate of the water inlet pipe 2511.

[0130] Specifically, the inlet solenoid valve 2512 has a high-level inlet mode and a low-level inlet mode.

[0131] Preferably, the water inlet pipe 2511 is installed in the water inlet hole of the water storage tank 210.

[0132] like Figure 7As shown, the drainage assembly 252 further includes a drain pipe 2521 and a drain pump 2522; the drain pump 2522 is installed in the water storage tank 210; the drain pump 2522 is connected to the inlet end of the drain pipe 2521, and the outlet end of the drain pipe 2521 is located outside the water storage tank 210. When the drain pump 2522 is started, it can draw water from the water storage tank 210 into the drain pipe 2521, thereby draining the water from the water storage tank 210.

[0133] It should be noted that the drainage trough 1010 is connected to the water storage tank 210 through the drainage assembly 252. The outlet end of the drainage pipe 2521 is also connected to the drainage trough. When the drainage pump 2522 is started, the drainage pump 2522 can draw water from the water storage tank 210 into the drainage pipe 2521 and discharge it into the drainage trough 1010.

[0134] In one embodiment of the present invention, such as Figure 1 As shown, the first side of the housing 100 has an outdoor air outlet 109 that communicates with the internal circulation channel 104, and the outdoor air outlet 109 is provided with an air outlet damper that can be opened or closed.

[0135] Understandably, this involves obtaining current indoor air quality. Specifically, indoor air quality can be determined using parameters such as bacterial concentration, carbon dioxide content, inhalable particulate matter content, and sulfur dioxide content.

[0136] If the current indoor air quality is lower than the first set quality, it indicates that the concentration of harmful gases in the indoor environment is too high and will affect health. In this case, the internal circulation channel 104 and the fresh air channel 103 are disconnected and the outdoor air outlet 109 is opened to quickly exhaust indoor air to the outside and introduce fresh outdoor air into the indoor environment through outdoor circulation.

[0137] It should be noted that during indoor circulation, the outdoor air outlet 109 is closed by the air outlet damper.

[0138] Based on the fresh air dehumidifier provided in any of the above embodiments, embodiments of the present invention also propose a control method for the fresh air dehumidifier, such as... Figure 13 As shown, the control method includes the following steps: Step 100: Obtain the current outdoor ambient temperature.

[0139] Step 200: If the current outdoor ambient temperature is lower than the set temperature, and the fresh air dehumidifier is running in humidification mode, control the heating module 400 and / or dehumidification module 300 to turn on in order to heat the air introduced by the fresh air inlet 101.

[0140] Step 300: If the current outdoor ambient temperature is lower than the set temperature, and the fresh air dehumidifier is operating in dehumidification mode, control the heating module 400 to open and / or connect the internal circulation channel 104 and the fresh air channel 103 to heat the air introduced by the fresh air inlet 101.

[0141] It is understood that a fresh air duct 103 and an internal circulation duct 104 are formed within the outer casing 100, and an internal circulation guide plate component 190 is provided between the fresh air duct 103 and the internal circulation duct 104. The internal circulation guide plate component 190 enables the connection and disconnection of the internal circulation duct 104 and the fresh air duct 103. In winter, when the outdoor ambient temperature is lower than the set temperature, if the fresh air dehumidifier is running in humidification mode, the heating module 400 can be turned on, the dehumidification module 300 can be turned on, or both the heating module 400 and the dehumidification module 300 can be turned on simultaneously to heat the air introduced by the fresh air inlet 101.

[0142] In winter, when the outdoor ambient temperature is lower than the set temperature, if the fresh air dehumidifier is running in dehumidification mode, the heating module 400 can be turned on, the internal circulation channel 104 and the fresh air channel 103 can be connected, and the heating module 400 can be turned on while the internal circulation channel 104 and the fresh air channel 103 are connected to heat the air introduced into the fresh air channel 103, so as to prevent low-temperature air from entering the indoor space and causing fluctuations in the indoor ambient temperature, thereby improving the user experience.

[0143] Optional, such as Figure 14 As shown, the control method further includes the following steps: Step 400: Obtain the current ambient humidity.

[0144] Step 500: When the current ambient humidity is greater than the preset humidity, control the second inlet to open.

[0145] It is understandable that by obtaining the current ambient humidity and, if the current ambient humidity is greater than the preset humidity, the second inlet 112 is opened to allow air to enter the first installation cavity 105 through the second inlet 112 without passing through the humidification module 200, thereby reducing the wind resistance caused by the air passing through the humidification module 200 and effectively reducing the workload of the air supply module 500.

[0146] Optionally, in step 400, the current ambient humidity can be the current outdoor ambient humidity, then step 500 specifically includes the following: The current outdoor ambient humidity is obtained. If the current outdoor ambient humidity is greater than the first preset humidity, the second inlet 112 is opened.

[0147] It is understandable that when the current outdoor humidity is greater than the first preset humidity, and when outdoor air circulation is in progress, the second inlet 112 is opened so that the outdoor air introduced by the fresh air inlet 101 enters the first installation cavity 105 through the second inlet 112 without passing through the humidification module 200, thereby reducing the wind resistance caused by the air passing through the humidification module 200 and effectively reducing the workload of the air supply module 500.

[0148] Optionally, in step 400, the current ambient humidity can be the current indoor ambient humidity, then step 500 specifically includes the following: If the current indoor humidity is greater than the second preset humidity, control the second inlet 112 to open.

[0149] It is understandable that when the current indoor humidity is greater than the second preset humidity, and during indoor circulation, the second inlet 112 is opened so that the indoor air introduced by the indoor air inlet 107 enters the first installation cavity 105 through the internal circulation air outlet 181 and the second inlet 112, without having to pass through the humidification module 200, thereby reducing the wind resistance caused by the air passing through the humidification module 200 and effectively reducing the workload of the air supply module 500.

[0150] It should be noted that the current ambient humidity can include both the current outdoor ambient humidity and the current indoor ambient humidity. When both the current outdoor ambient humidity and the current indoor ambient humidity are greater than the corresponding preset humidity, you can choose indoor circulation, outdoor circulation, or both at the same time. By controlling the second inlet 112 to open, the workload of the air supply module 500 can be reduced.

[0151] Optionally, the control method further includes the following: When the current ambient humidity is less than or equal to the preset humidity, control the second inlet 112 to close.

[0152] Understandably, under outdoor circulation, if the current outdoor ambient humidity is less than or equal to the first preset humidity, the second inlet 112 is closed, so that the outdoor air introduced by the fresh air inlet 101 enters the humidification module 200 through the first inlet 111 for humidification.

[0153] In indoor circulation mode, if the current indoor ambient humidity is less than or equal to the second preset humidity, the second inlet 112 is closed, so that the indoor air introduced by the indoor air inlet 107 enters the humidification module 200 through the internal circulation air outlet 181 and the first inlet 111 for humidification.

[0154] Optionally, the control method further includes the following: Optional, such as Figure 15As shown, the control method further includes the following steps: Step 600: Obtain the current indoor air quality.

[0155] Step 700: When the current indoor air quality is lower than the first set quality, control the disconnection of the internal circulation channel and the fresh air channel and open the outdoor air outlet.

[0156] Understandably, the system acquires the current indoor humidity. If the current indoor humidity is outside the preset range, and the outdoor environment is favorable, the internal circulation channel 104 and the fresh air channel 103 are disconnected, allowing outdoor air to be introduced into the room via the fresh air channel 103. Conversely, if the outdoor environment is unfavorable or the temperature is extreme, and the current indoor oxygen content exceeds the first preset oxygen content, the internal circulation channel 104 and the fresh air channel 103 are connected, allowing indoor air to be reintroduced into the room via the internal circulation channel 104 and the fresh air channel 103. This effectively ensures good indoor air quality and improves the user experience. It should be noted that the fresh air channel 103 is equipped with a humidification device. As air passes through the fresh air channel 103, it can humidify or dehumidify the air, thus regulating the indoor humidity. Furthermore, the fresh air channel 103 can also be equipped with a heat exchange module to heat or cool the air, thereby regulating the indoor temperature.

[0157] Optionally, the control method may also include the following: If the current indoor humidity is not within the preset humidity range, and the current outdoor air quality is greater than the second set quality, the fresh air inlet 101 is opened and the internal circulation channel 104 and the fresh air channel 103 are disconnected.

[0158] It is understandable that the current outdoor air quality is greater than the second set quality, indicating that the outdoor air quality is good. Therefore, the fresh air inlet 101 is opened and the internal circulation channel 104 and the fresh air channel 103 are disconnected.

[0159] Optionally, the control method may also include the following: When the current indoor humidity is not within the preset humidity range, control the fresh air inlet 101 to open at least partially and the internal circulation channel 104 and the fresh air channel 103 to be partially connected.

[0160] Understandably, if the current indoor humidity is not within the preset humidity range, and the outdoor environment is good, and the current indoor oxygen content is greater than the first preset oxygen content, the fresh air inlet 101 will be opened at least partially, and the internal circulation channel 104 and the fresh air channel 103 will be partially connected, so as to achieve simultaneous indoor and outdoor circulation.

[0161] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
