Description

Technical Field

[0001] This invention relates to the field of air conditioning equipment technology, specifically to a humidification module and a fresh air conditioner with the same, and a control method thereof. Background Technology

[0002] As people's living standards continue to improve, their demands for their living environment are also constantly increasing. Indoors, people are paying more and more attention to air quality. While there are increasingly more fresh air conditioners and humidifiers on the market, most offer only single functions and fail to combine fresh air and humidification to enhance the user experience. Conventional solutions include fresh air and humidification modules, but these modules operate independently, failing to effectively integrate the fresh air and humidification system with the air conditioning system, resulting in wasted resources. Summary of the Invention

[0003] Therefore, the present invention provides a humidification module and a fresh air conditioner having the same, as well as a control method, to solve the problems of complex structure and poor humidification effect of existing humidification modules.

[0004] This invention provides a humidification module, comprising:

[0005] A volute assembly has a volute cover, a volute, and a sealing plate arranged sequentially; a fan is provided between the volute cover and the volute; a first air outlet cavity is formed between the volute cover and the volute, and an air outlet is provided at the upper part of the first air outlet cavity;

[0006] A wet film assembly includes a wet film and a wet film frame for fixing the wet film; a mixing chamber is formed between the volute and the wet film frame, and an air inlet is provided at the bottom of the mixing chamber; under the action of the fan, the air to be humidified enters the mixing chamber through the air inlet, flows from bottom to top across the surface of the wet film, enters the first air outlet chamber through the mixing chamber, and is finally discharged through the air outlet;

[0007] A water inlet cavity is formed between the wet film frame and the sealing plate. The water inlet cavity is provided with a water inlet. Humidifying condensate enters the water inlet cavity through the water inlet. The water inlet cavity is connected to the mixing cavity.

[0008] The wet film has a capillary effect on the condensate water for humidification. When the air to be humidified flows from bottom to top across the surface of the wet film, the condensate water for humidification is continuously adsorbed onto the wet film, thereby humidifying the air flowing across the surface of the wet film.

[0009] Optionally, a first air outlet is formed on the upper part of the volute cover, and a second air outlet is formed on the upper part of the volute; the first air outlet and the second air outlet constitute the air outlet; the water inlet is disposed on the sealing plate.

[0010] Further optionally, the wet film frame has a wet film mounting cavity disposed within the wet film frame and a wet film mounting port disposed on one side of the wet film mounting cavity; the wet film can be installed into the wet film mounting cavity through the wet film mounting port.

[0011] Alternatively, the wet film mounting port has a cover plate, which is detachably connected to the volute for replacing the wet film.

[0012] The present invention also provides a fresh air conditioner, which has a second air outlet cavity, a bottom shell, a controller, and a humidification module as described in any one of the above; the bottom shell has a water channel for accumulating condensate; the second air outlet cavity is connected to the air inlet of the humidification module, and the air to be humidified in the second air outlet cavity enters the mixing cavity through the air inlet; the water channel is connected to the water inlet of the humidification module, and the condensate in the water channel enters the water inlet cavity through the water inlet and is adsorbed onto the wet film.

[0013] Optionally, a first solenoid valve is provided between the second air outlet and the air inlet. By controlling the first solenoid valve, the amount of air entering the mixing chamber can be controlled. A second solenoid valve is provided between the water channel and the water inlet. By controlling the second solenoid valve, the amount of condensate entering the water inlet chamber can be controlled. The fresh air conditioner also has a detection module for detecting indoor humidity. The controller is electrically connected to the first solenoid valve, the second solenoid valve, and the detection module, respectively, for receiving data transmitted by the detection module and controlling the first and second solenoid valves to operate, so that the indoor humidity reaches the preset humidity.

[0014] Optionally, the fresh air conditioner has a humidification mode and other modes. When the fresh air conditioner is in humidification mode, firstly, the controller controls the second solenoid valve to open, and the condensate in the water channel enters the water inlet chamber and is adsorbed onto the wet film. Secondly, the controller controls the first solenoid valve to open, and the air to be humidified in the second air outlet chamber enters the mixing chamber through the air inlet, mixes with the condensate on the surface of the wet film and is converted into water vapor, which is then discharged into the room through the first air outlet chamber and the air outlet.

[0015] When the fresh air conditioner is in other modes, the controller controls the first and second solenoid valves to close, so that the air in the second air outlet chamber cannot enter the mixing chamber, and the condensate in the water channel cannot enter the water inlet chamber. At this time, the humidification module does not affect the performance of the fresh air conditioner.

[0016] Optionally, the detection module has a humidity sensor, which detects the indoor humidity H1 and transmits the detection data to the controller. The controller determines whether H0 is less than a first preset humidity H1. When the indoor humidity H0 is less than the first preset humidity H1, the controller controls the fresh air conditioner to enter the humidification mode.

[0017] The present invention also provides a control method for the humidification mode of a fresh air conditioner as described in any one of the above claims, comprising:

[0018] S1. The humidity sensor detects the indoor humidity H1 and transmits the detection data to the controller. The controller determines whether H0 is less than the preset humidity H1.

[0020] S3. The controller controls the second solenoid valve to open, and the condensate in the water channel enters the water inlet chamber and is adsorbed onto the wet film.

[0021] S4. The controller controls the opening of the first solenoid valve and the operation of the fan;

[0022] S5. The air to be humidified in the second air outlet cavity enters the mixing cavity through the air inlet, mixes with the water on the wet film, and is converted into water vapor, which is then discharged into the room through the first air outlet cavity and the air outlet.

[0023] Further optionally, S3 includes:

[0024] S31. When the indoor humidity H0 is less than the first preset humidity H1 and greater than the second preset humidity H1, the controller controls the second solenoid valve to open and start timing. The condensate in the water channel enters the water inlet chamber and is adsorbed onto the wet film.

[0025] S32. When the timing time T0 is greater than the first preset time T1, the controller controls the second solenoid valve to close, and jumps to step S4;

[0026] S33. When the indoor humidity H0 is less than the second preset humidity H1, the controller controls the second solenoid valve to open and start timing, and the condensate in the water channel enters the water inlet chamber and is adsorbed onto the wet film.

[0027] S34. When the timing time T0 is greater than the second preset time T2, the controller controls the second solenoid valve to close and jumps to step S4.

[0028] Further optionally, when the indoor humidity H0 is greater than the first preset humidity H1, the controller controls the first solenoid valve and the second solenoid valve to close and the fan to stop running.

[0029] This invention incorporates a humidification device on a fresh air conditioner. The device comprises a volute assembly and a wet film assembly. The sealing plate of the humidification device has a water inlet connected to the water channel of the fresh air conditioner, allowing condensate to enter the inlet chamber and be absorbed onto the wet film. The volute assembly has an air inlet connected to the air outlet chamber of the fresh air conditioner, allowing air to enter the mixing chamber and mix with the water on the wet film, converting it into water vapor which is then discharged into the room through the air outlet of the humidification device, achieving a humidification effect. Electromagnetic valves are installed at both the water inlet and air inlet of the humidification device. By controlling the opening of these valves, the humidification mode of the fresh air conditioner is automatically controlled.

[0046] Example

[0047] <Snail Shell Component>

[0048] like Figure 1a and Figure 1b As shown, the humidification module provided in this embodiment includes a volute assembly 1 and a wet film assembly 2; wherein the volute assembly 1 has a volute cover 11, a volute 12 and a sealing plate 13 arranged in sequence, and a fan 112 is provided between the volute cover 11 and the volute 12; the volute 12 has an air inlet 123 at the lower end and an air outlet at the upper end; the sealing plate 13 has a water inlet 131; the wet film assembly 2 is disposed between the volute 12 and the sealing plate 13, and includes a wet film frame 21 and a wet film 22 fixed on the wet film frame 21; condensate enters through the water inlet 131 and wets the wet film 22.

[0049] Under the action of the fan 112, air enters the humidification module through the air inlet 123, mixes with the water droplets on the wet film 22, and is converted into water vapor, which is discharged into the room through the air outlet.

[0050] Preferably, a first air outlet cavity is formed between the volute cover 11 and the volute 12, and the fan 112 is disposed in the first air outlet cavity; specifically, a mounting hole 113 is provided in the middle of the volute cover 11, and the fan shaft is mounted in the mounting hole 113 by a bearing. A first air outlet 111 is formed on the side near the volute cover 11, and a second air outlet 121 is formed on the side near the volute 12; when the volute cover 11 and the volute 12 are installed, the first air outlet 111 and the second air outlet 121 constitute an air outlet and communicate with the first air outlet cavity; specifically, the air outlet faces upward.

[0051] Preferably, the volute 12 is provided with an air inlet cavity 124 communicating with the air inlet 123. Specifically, the air inlet cavity 124 is located at the lower end of the volute 12 near the air inlet 123. The air inlet 123 faces rearward, and air enters the air inlet cavity 124 through the air inlet 123. The volute 12 is provided with a grille 122, the position of which corresponds to the position of the fan 112.

[0052] Preferably, a mixing chamber 125 is formed between the volute 12 and the wet film frame 21, and the mixing chamber 125 and the first air outlet chamber are separated by a grille 122; the mixing chamber 125 and the first air outlet chamber are connected by a through hole on the grille 122, and the mixing chamber 125 is connected to the air inlet chamber 124.

[0053] Specifically, air enters the air inlet chamber 124 through the air inlet 123, then enters the mixing chamber 125, mixes with the water on the wet film 22, and humidifies the air. Large particles in the air are then filtered out by the grille 122 on the volute 12, enter the first air outlet chamber, and are finally discharged through the air outlet.

[0054] <Wet film assembly>

[0055] like Figure 1a and Figure 1b As shown, the wet film frame 21 provided in this embodiment has a wet film mounting cavity 211 disposed in the wet film frame 21 and a wet film mounting port 23 disposed on one side of the wet film mounting cavity 211; the wet film 22 can be installed in the wet film mounting cavity 211 through the wet film mounting port 23.

[0056] Preferably, the upper and lower walls of the wet film mounting cavity 211 have wet film mounting grooves 212, the size of which corresponds to the size of the wet film 22; when the wet film 22 is installed in the wet film mounting cavity 211, the wet film 22 can be locked in the wet film mounting groove 212; in order to prevent the wet film 22 from falling out of the wet film mounting cavity 211 and affecting the mixing efficiency of the air in the mixing cavity 125 and the water droplets on the wet film 22, there are baffles on the left and right sides of the wet film mounting cavity 211, the baffles separate the mixing cavity 125 from the wet film mounting cavity 211, and the mixing cavity 125 and the wet film mounting cavity 211 are connected through the through holes on the baffles.

[0057] Preferably, in order to seal the wet film installation port 23 and facilitate the replacement of the wet film 22, a cover plate 24 is provided at the wet film installation port 23, and the size of the cover plate 24 corresponds to the size of the wet film installation port 23; the cover plate 24 is connected to the volute 12 through a detachable structure.

[0058] Specifically, the upper end of the cover plate 24 has a buckle 241, and the volute 12 has a groove 126 at the position opposite to the buckle 241 of the cover plate 24. The cover plate 24 can be installed on the volute 12 by the cooperation of the buckle 241 and the groove 126. When it is necessary to install or replace the wet membrane 22, the cover plate 24 is removed from the volute 12, the wet membrane 22 is placed in the wet membrane installation cavity 211 through the wet membrane installation port 23, and the wet membrane 22 is locked in the wet membrane installation groove 212. Then the cover plate 24 is installed on the volute 12.

[0059] Preferably, a water inlet cavity is formed between the wet film frame 21 and the sealing plate 13. The water inlet cavity is connected to the water inlet 131. Humidifying condensate enters the water inlet cavity through the water inlet 131 and is adsorbed onto the wet film 22, thus wetting the wet film 22.

[0060] <Fresh Air Conditioner>

[0061] like Figure 2a and Figure 2b As shown, the fresh air conditioner provided in this embodiment has a second air outlet cavity, a bottom shell 31, a controller and the humidification module described above. The bottom shell 31 has a water channel 311, which can accumulate condensate generated by the evaporator of the fresh air conditioner. The second air outlet cavity is located at the lower end of the rear side of the fresh air conditioner 3, corresponding to the position of the air inlet 123 of the humidification module. The water channel 311 extends to the humidification water inlet 131.

[0062] Preferably, the humidification module is located on the left side of the fresh air conditioner 3. The air inlet 123 at the lower end of the volute 12 is connected to the second air outlet of the fresh air conditioner 3 through a pipe. The air processed by the fresh air conditioner 3 can enter the mixing chamber through the second air outlet and the air inlet 123. The end of the water channel 311 is connected to the water inlet 131. The condensate generated by the fresh air conditioner 3 enters the water inlet chamber through the water channel 311 and the water inlet 131 and is adsorbed onto the wet film 22, which can wet the wet film 22.

[0063] <Control Section>

[0064] like Figure 2a and Figure 2b As shown, the fresh air conditioner provided in this embodiment has a fan 112 with at least one power. By controlling the fan 112 to operate at different power, the contact time between the air in the mixing chamber 125 and the water on the wet film 22 can be controlled to achieve a high-efficiency humidification effect.

[0065] Specifically, the fan 112 has a first power and a second power. When the fan 112 operates at the first power, the air speed is greater than that when the fan 112 operates at the first power. This results in a short contact time between the air entering the mixing chamber 125 and the water on the wet film 22 when the fan 112 operates at the first power, leading to a low air humidification effect. When the fan 112 operates at the second power, the air entering the mixing chamber 125 and the water on the wet film 22 have a long contact time, resulting in a high air humidification effect.

[0066] Preferably, a first solenoid valve is provided in the connecting pipe between the second air outlet chamber and the air inlet 123. By controlling the opening and closing of the first solenoid valve, the amount of air entering the humidification module can be controlled. Specifically, when the first solenoid valve is open, the second air outlet chamber is connected to the air inlet chamber 124, and the air in the second air outlet chamber can enter the air inlet chamber 124. When the first solenoid valve is closed, the second air outlet chamber is not connected to the air inlet chamber 124, and the air in the second air outlet chamber cannot enter the air inlet chamber 124.

[0067] Preferably, a second solenoid valve is provided in the connecting pipe between the water channel 311 and the water inlet 131. By controlling the opening and closing of the second solenoid valve, the amount of condensate entering the water inlet chamber can be controlled. Specifically, when the second solenoid valve is open, the water channel 311 is connected to the water inlet chamber, and the condensate accumulated in the water channel 311 can enter the water inlet chamber; when the second solenoid valve is closed, the water channel 311 is not connected to the water inlet chamber, and the condensate accumulated in the water channel 311 cannot enter the water inlet chamber.

[0068] Preferably, the fresh air conditioner also has a detection module for detecting indoor humidity; the controller is electrically connected to the fan 112, the first solenoid valve, the second solenoid valve, and the detection module respectively, on the one hand receiving the data transmitted by the detection module, and on the other hand controlling the fan 112, the first solenoid valve, and the second solenoid valve to achieve the preset humidity.

[0069] Preferably, the fresh air conditioner has a humidification mode and other modes; when the fresh air conditioner is in the humidification mode, firstly, the controller controls the second solenoid valve to open, and the condensate in the water channel enters the water inlet chamber, is adsorbed onto the wet film 22, and wets the wet film 22; secondly, the controller controls the first solenoid valve to open and the fan to run, and the air in the second air outlet chamber enters the mixing chamber 125 through the air inlet 123, mixes with the condensate on the surface of the wet film 22 and is converted into water vapor, which is discharged into the room through the first air outlet chamber and the air outlet.

[0070] When the fresh air conditioner is in other modes, the controller closes the first and second solenoid valves and stops the fan 112. The air in the second air outlet chamber cannot enter the mixing chamber 125, and the condensate in the water channel 311 cannot enter the water inlet chamber. At this time, the fresh air conditioner operates normally in other modes, and the humidification module is not connected to the fresh air conditioner and does not affect the performance of the fresh air conditioner.

[0071] Preferably, the wet film 22 has different wettability when the amount of condensate entering the water inlet chamber is different. The wet film 22 can achieve different wettability by controlling the opening time of the second solenoid valve.

[0072] Specifically, the wet film 22 has a first wettability and a second wettability; when the wet film 22 is at the first wettability, the amount of water adhering to the surface of the wet film 22 is small and the contact area with the air is small; when the wet film 22 is at the second wettability, the amount of water adhering to the surface of the wet film 22 is large and the contact area with the air is large.

[0073] Preferably, the detection module is a humidity sensor. The humidity sensor detects the indoor humidity H1 and transmits the detection data to the controller. The controller determines whether H0 is less than the first preset humidity H1. When the indoor humidity H0 is less than the first preset humidity H1, the controller controls the fresh air conditioner to enter the humidification mode.

[0074] <Control Methods>

[0075] like Figure 3 As shown, the control method for the humidification mode of the fresh air conditioner provided in this embodiment includes:

[0076] S1. Use a humidity sensor to detect the indoor humidity H0 and transmit the detection data to the controller. The controller determines whether H0 is less than the preset humidity H1.

[0077] S2. When the indoor humidity H0 is less than the preset humidity H1, the controller controls the fresh air conditioner to enter the humidification mode.

[0078] S3. The controller controls the second solenoid valve to open, and the condensate accumulated in the water channel 311 enters the water inlet chamber through the water inlet 131, is adsorbed onto the wet film 22, and wets the wet film 22.

[0079] S4. The controller controls the opening of the first solenoid valve and the operation of the fan 112;

[0080] S5. Under the action of the fan, the air in the second air outlet chamber enters the mixing chamber 125 through the air inlet 123, mixes with the water on the wet film 22, and is converted into water vapor, which is discharged into the room through the first air outlet chamber and the air outlet.

[0081] Preferably, step S3 includes:

[0082] S31. When the indoor humidity H0 is less than the first preset humidity H1 and greater than the second preset humidity H1, the controller controls the second solenoid valve to open and starts timing. The condensate accumulated in the water channel 311 enters the water inlet chamber, is adsorbed onto the wet film 22, and wets the wet film 22.

[0083] S32. When the timing time T0 is greater than the first preset time T1, the wet film 22 reaches the first wetness level, the controller controls the second solenoid valve to close, and jumps to step S41.

[0084] S33. When the indoor humidity H0 is less than the second preset humidity H1, the controller controls the second solenoid valve to open and starts timing. The condensate accumulated in the water channel 311 enters the water inlet chamber, is adsorbed onto the wet film 22, and wets the wet film 22.

[0085] S34. When the timing time T0 is greater than the second preset time T2, the wet film 22 reaches the second wetness level, the controller controls the second solenoid valve to close, and jumps to step S42.

[0086] Preferably, step S4 includes:

[0087] S41, the controller controls the fan 112 to run at the first power. At this time, the air entering the humidification module has a faster speed and a shorter contact time with the water on the wet film 22.

[0088] S42, the controller controls the fan 112 to run at the second power; at this time, the air entering the humidification module is slower and has a longer contact time with the water on the wet film 22.

[0089] Preferably, when the indoor humidity H0 is greater than the first preset humidity H1, the controller controls the first solenoid valve and the second solenoid valve to close and the fan 112 to stop running.
