[0054] In another embodiment of the utility model, as shown in Figures 1 to 3 The air inlet side plate 110 is provided with the first inlet 111 and the second inlet 112 which are arranged at intervals, the second inlet 112 is provided with the first guide plate component 150 which can be opened or closed, the air outlet side plate 120 is provided with the first outlet 121 and the second outlet 122 which are arranged at intervals, the first inlet 111, the humidification module 200 and the first inlet 111 are sequentially arranged along a first direction, the second inlet 112, the second outlet 122 and the air supply module 500 are sequentially arranged along the first direction, and the second inlet 112 and the humidification module 200 are arranged in a staggered manner. It should be noted that the air outlet side plate 120 can also be provided with a long hole arranged along a second direction, one side of the long hole serves as the first outlet 121, and the second side of the long hole serves as the second outlet 122.

[0055] It can be understood that the shell 100 is provided with the fresh air inlet 101 and the indoor air outlet 102 which are arranged in a relative manner, 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 an indoor space through the indoor air outlet 102. The side wall of the first installation cavity 105 close to the fresh air inlet 101 (i.e. the inlet side of the humidification module 200) forms the first inlet 111 and the second inlet 112 which are arranged at intervals along the second direction, the side wall of the first installation cavity 105 close to the indoor air outlet 102 (i.e. the outlet side of the humidification module 200) forms the first outlet 121 and the second outlet 122 which are arranged at intervals along the second direction, the first inlet 111, the humidification module 200 and the first outlet 121 are arranged in a relative manner along the first direction, the second inlet 112 and the second outlet 122 are arranged in a relative manner along the first direction, the humidification module 200 and the second outlet 122 are arranged in a staggered manner along the second direction, then the first inlet 111, the humidification module 200 and the first outlet 121 form a humidification channel, the second inlet 112 and the second outlet 122 form an air channel, and the first guide plate component 150 which can be opened or closed is arranged at the second inlet 112 to realize the connection and disconnection of the air channel.

[0056] Specifically, when the first guide plate component 150 opens the second inlet 112, the outdoor air entering through the fresh air inlet 101 is divided into two paths, one path enters the air supply module 500 in the second installation cavity 106 through the first inlet 111, the humidification module 200 and the first outlet 121, and the other path enters the air supply module 500 in the second installation cavity 106 through the second inlet 112 and the second outlet 122; when the first guide plate component 150 closes the second inlet 112, the outdoor air entering through the fresh air inlet 101 enters the air supply module 500 in the second installation cavity 106 through the first inlet 111, the humidification module 200 and the first outlet 121.

[0057] It can be understood 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 and does not need to pass through the humidification module 200, thereby reducing the air resistance caused by the humidification module 200, effectively reducing the working load of the air supply module 500, and further reducing the energy consumption in the operation process of the fresh air humidification machine.

[0078] In this embodiment, by setting the spraying part 280, the spraying part 280 directly sprays water mist to the air flowing from the inner air inlet to the inner air outlet 222, so that the air can fully contact with the water mist during flowing through the protective shell 220, thereby realizing rapid and efficient humidification effect. Compared with the traditional evaporation or steam humidification method, this method can change the air humidity faster to meet the demand of rapid humidification. The close cooperation of the water storage tank 210 and the protective shell 220 makes the whole humidification module 200 compact in structure and small in floor area. At the same time, the design of the protective shell 220 also effectively protects the spraying part 280, avoiding the interference and damage of the external environment, improving the durability and service life of the equipment. The water outlet end of the spraying part 280 is located in the protective shell 220, so that the water mist can be effectively prevented from directly contacting the user or the electrical equipment, thereby improving the safety of use.

[0079] As shown in Figure 6 and Figure 7As shown, in some embodiments, the spraying component 280 comprises a spraying pump 281, a first spraying pipe 282 and a first spraying head; the spraying pump 281 is installed on the water storage tank 210; a water outlet end of the spraying pump 281 is communicated with a water inlet end of the first spraying pipe 282, for pumping water in the water storage tank 210 into the first spraying pipe 282; the first spraying head is located in the protective shell 220; the first spraying head is communicated with a water outlet end of the first spraying pipe 282, for spraying water mist to the air flowing from the inner air inlet to the inner air outlet 222.

Specifically, when the spraying pump 281 works at a high gear, the pressure of the first spraying head can be made greater, the water mist formed is more fine, and the air humidification degree is improved. When the spraying pump 281 works at a low gear, the pressure of the first spraying head can be made smaller, the water mist formed is less, and the air humidification degree is reduced.

[0081] Preferably, the spraying component 280 comprises a plurality of first spraying heads; the plurality of first spraying heads are arranged in a second direction and are all communicated with the first spraying pipe 282.

By arranging the water drainage groove 1010 on the outer side of the water storage groove 210 and close to the inner air inlet, air needs to pass above the water drainage groove 1010 and then enter the inner air inlet. At this time, the water drainage groove 1010 is partially gasified by absorbing heat of surrounding components, and the air carries the gasified water molecules to realize primary humidification of the air.

[0096] Further, the side wall of the first mounting cavity 105 is provided with a water overflow port communicating the water drainage groove 1010 and the water storage groove 210.

[0097] Specifically, the air inlet side plate 110 is provided with a water overflow port having a certain height. When the water level of the water storage groove 210 reaches a preset height, the water in the water storage groove 210 is drained to the water drainage groove 1010 through the water overflow port.

In this way, the actual water amount in the water drainage groove 1010 can be prevented from exceeding the upper limit of the water amount, and water overflow can be avoided. By arranging the alarm device, the user can be reminded to drain the water in the water drainage groove 1010 in time.

[0100] In an embodiment of the utility model, the third mounting cavity 108 is provided with a dehumidification module 300. When the air humidity is too high, the dehumidification module 300 is used for dehumidifying the air to avoid that the air humidity in the room is too high.

[0101] Optionally, the dehumidification module 300 is arranged in the second air duct 1062, and the dehumidification module 300 comprises an evaporator and an evaporator support. The evaporator is installed in the shell 100 through the evaporator support and can be connected with a compressor to realize heat exchange with the air, so as to heat exchange and cool or evaporate and dehumidify the air.

[0106] In addition, the wet membrane humidification component 230 in the embodiment can also cooperate with the spray component 280 to adapt to different humidification requirements, thereby improving the experience of the whole device.

The unique structure of the wet membrane can provide the maximum contact area between air and its surface, and each square meter of the membrane body can provide a contact area of 500-600 m 2 When dry and hot air passes through the wet membrane, the water fully absorbs the heat of the air and vaporizes and evaporates, so that the air achieves the purpose of humidification. In this humidification process, the humidity of the air increases, the temperature decreases, but the enthalpy of the air remains unchanged.

By arranging the protective frame 2314, the wet film rotating member 2313 can be protected.

[0121] Preferably, a wet film material layer is arranged on the outer side of the protective frame 2314, which can further increase the contact area between air and water and improve the humidifying speed.

[0124] Preferably, the reinforcing rib 2318 has a circular ring structure, and the plurality of crossbeams 2317 are arranged along the circumference of the circular ring-shaped reinforcing rib 2318.

[0125] As shown, Figures 6 to 10 In some embodiments, the humidifying module 200 further comprises a first water level detection component 240 and a water amount adjusting 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 amount in the water storage tank 210; the water amount adjusting component 250 is installed on the water storage tank 210 and is used to adjust the actual water amount in the water storage tank 210, so that the actual water amount is not less than a first water amount threshold and not greater than a second water amount threshold; the first water amount threshold is less than the second water amount threshold.

[0126] In this embodiment, the actual water amount in the water storage tank 210 is maintained within a certain range, which can avoid the situation that the water amount is too small to ensure the humidifying effect, and also can avoid the situation that the water amount is too large to waste water.

[0127] Further, the water amount adjusting component 250 comprises a water inlet assembly 251 and a water outlet assembly 252; the water inlet assembly 251 has a high gear water adding mode and a low gear water adding mode; the water outlet assembly 252 has an open state and a closed state; when the actual water amount is less than the first water amount threshold, the water inlet assembly 251 operates in the high gear water adding mode; when the actual water amount is within the water amount balance threshold range, the water inlet assembly 251 operates in the low gear water adding mode; when the actual water amount is greater than the second water amount threshold, the water outlet assembly 252 is switched from the closed state to the open state for discharging water in the water storage tank 210; the minimum water amount balance threshold of the water amount balance threshold range is greater than the first water amount threshold, and the maximum water amount balance threshold of the water amount balance threshold range is less than the second water amount threshold.

Specifically, when the actual humidity of indoor air is less than the set humidity, the control component controls the wet film humidification component 230 to switch to high gear humidification, and at this time, the wet film humidification component 230 rotates fast. When the actual humidity of indoor air reaches the set humidity, the control component controls the wet film humidification component 230 to switch to low gear humidification, and at this time, the rotation speed of the wet film humidification component 230 is reduced.

[0133] Further, the first water level detecting component 240 comprises a guide rod, a floating ball and a water level sensor; the floating ball is installed on the guide rod; the water level sensor is installed on the floating ball, and the floating ball moves up and down along the guide rod with the up and down of the water level. The water level sensor is used for detecting the water level in the water storage tank 210, and transmitting an electric signal representing the water level to the control component. After receiving the electric signal, the control component calculates the actual water amount in the water storage tank 210, and then compares the actual water amount with the first water amount threshold, the second water amount threshold and the water amount balance threshold range. Finally, different control instructions are output according to the comparison result.

[0134] Preferably, the second water level detecting component 290 is the same as the first water level detecting component 240 in structure.

[0135] As shown in Figure 6 and Figure 7 , the water inlet assembly 251 comprises a water inlet pipe 2511 and a water inlet electromagnetic valve 2512; one end of the water inlet pipe 2511 is located outside the water storage tank 210 and communicates with a water source; the other end is located inside the water storage tank 210. The water inlet electromagnetic valve 2512 is installed on the water inlet pipe 2511 and is used for adjusting the water inlet amount of the water inlet pipe 2511.

[0136] Specifically, the water inlet electromagnetic valve 2512 has a high gear water inlet mode and a low gear water inlet mode.

[0137] Preferably, the water inlet pipe 2511 is installed in the water inlet hole of the water storage tank 210.

[0138] As shown in Figure 7 , further, the water drainage assembly 252 comprises a drainage pipe 2521 and a drainage pump 2522; the drainage pump 2522 is installed on the water storage tank 210; the drainage pump 2522 communicates with the water inlet end of the drainage pipe 2521, and the water outlet end of the drainage pipe 2521 is located outside the water storage tank 210. Starting the drainage pump 2522, the drainage pump 2522 can suck the water in the water storage tank 210 into the drainage pipe 2521, so as to drain the water storage tank 210.

[0139] It should be noted that the drainage tank 1010 is communicated with the water storage tank 210 through the water drainage assembly 252. The water outlet end of the drainage pipe 2521 is also connected with the drainage tank 1010. Starting the drainage pump 2522, the drainage pump 2522 can suck the water in the water storage tank 210 into the drainage pipe 2521 and drain it to the drainage tank 1010.

[0140] In an embodiment of the present application, as shown in Figure 1 , the first side of the shell 100 has an outdoor air outlet 109 communicated with the internal circulation channel 104, and the outdoor air outlet 109 is provided with an openable or closable air outlet damper.

[0141] It can be understood that the current indoor air quality is obtained. Specifically, the indoor air quality can be determined by parameters such as bacterial concentration, carbon dioxide content, inhalable particle content, sulfur dioxide content, etc.

[0142] In the case that the current indoor air quality is lower than the first set quality, which indicates that the concentration of harmful gas in the indoor environment is too high to affect the health of the human body, the disconnection of the inner circulation channel 104 and the fresh air channel 103 and the opening of the outdoor air outlet 109 by the air outlet damper are controlled, so as to quickly exhaust the indoor air to the outdoor environment and introduce the outdoor fresh air into the indoor environment through the outdoor circulation.

[0143] It should be noted that the outdoor air outlet 109 is closed by the air outlet damper during the indoor circulation.

[0144] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
