Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, for example, to a humidifier and a fresh air blower. Background Art

[0002] Humidity refers to the amount of water vapor in the air. The human body's perception of air humidity is affected by the season, temperature, and other environmental factors. For example, in the summer, the human body generally feels comfortable with a humidity range of 30% to 60%. In the winter, the human body's comfortable humidity range tends to expand to 30% to 80%. In addition to the season and temperature, the human body's perception of humidity may also be affected by other factors, such as activity level, clothing, and individual differences. Therefore, in real life, it is often necessary to adjust the indoor humidity according to the specific situation to achieve the best human comfort.

[0003] However, the traditional fresh air humidification device can only humidify the air at a certain fixed humidification intensity and cannot flexibly adjust the humidification intensity.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0006] The embodiments of the present disclosure provide a humidifier and a fresh air blower, which improve the flexibility of the humidifier in regulating air humidity and enhance the user experience.

[0007] In some embodiments, a humidifier is provided, comprising: a housing, comprising a humidifying chamber, an air inlet and an air outlet connected to the humidifying chamber; a humidifying mechanism, located in the humidifying chamber, for humidifying the air in the humidifying chamber; a swing blade assembly, arranged in the housing, located at the air inlet and / or the air outlet, for controlling the air volume passing through the air inlet and / or the air outlet.

[0008] The humidifier provided by the embodiment of the present disclosure can humidify the air in the humidification chamber by using a humidification mechanism arranged in the housing and located in the humidification chamber. At the same time, by using a swing blade assembly arranged in the housing and located at the air inlet and / or the air outlet, the through area between the air inlet and / or the air outlet and the humidification chamber is adjusted, thereby controlling the air volume passing through the air inlet and / or the air outlet, and realizing flexible control of the humidification intensity of the humidifier for the surrounding air. Specifically, when it is necessary to increase the humidification intensity of the humidifier for the surrounding air, the through area between the air inlet and / or the air outlet and the humidification chamber is increased to increase the air volume passing through the air inlet and / or the air outlet, thereby improving the humidification efficiency of the humidifier, thereby improving the humidification intensity of the humidifier; when it is necessary to reduce the humidification intensity of the humidifier for the surrounding air, the through area between the air inlet and / or the air outlet and the humidification chamber is reduced to reduce the air volume passing through the air inlet and / or the air outlet, thereby reducing the humidification efficiency of the humidifier, thereby reducing the humidification intensity of the humidifier. Therefore, the humidifier provided by the present invention improves the flexibility of the humidifier in regulating air humidity. Compared with the related art, it can meet the different humidity requirements of users and improve the user experience.

[0009] Optionally, the swing blade assembly includes: a swing blade motor, which is arranged on the box body near the air inlet and / or air outlet; a swing blade, which is connected to the output end of the swing blade motor, and the swing blade motor is used to drive the swing blade to rotate relative to the box body to adjust the connection area between the air inlet and / or air outlet and the humidification chamber.

[0010] In this embodiment, the swing blade motor is used as a power device and is arranged near the air inlet and / or the air outlet of the box body to drive the swing blade to rotate relative to the box body.

[0024] In this embodiment, the first air vent is connected to the outdoor air inlet, the second air vent is connected to the outdoor air outlet, and the third air vent is connected to the fresh air chamber and the humidity control chamber. When the driving component drives the first door body and the second door body to move relative to the shell, the switching between opening the first air vent and the second air vent, closing the third air vent and closing the first air vent and the second air vent, and opening the third air vent is realized, thereby realizing the switching of the flow direction of the air flow between the fresh air chamber and / or the humidity control chamber.

[0067] In some embodiments, in combination Figures 1 to 5 As shown, a humidifier 100 is provided, including a housing 110, a humidifying mechanism 120 and a swing blade assembly 130. The housing 110 includes a humidifying chamber, an air inlet 1124 and an air outlet 1126 connected to the humidifying chamber. The humidifying mechanism 120 is located in the humidifying chamber and is used to humidify the air in the humidifying chamber. The swing blade assembly 130 is arranged in the housing 110, located at the air inlet 1124 and / or the air outlet 1126, and is used to control the air volume passing through the air inlet 1124 and / or the air outlet 1126.

[0068] The humidifier 100 provided in the embodiment of the present disclosure can humidify the air in the humidification chamber by using the humidification mechanism 120 disposed in the housing 110 and located in the humidification chamber. At the same time, by using the swing blade assembly 130 disposed in the housing 110 and located at the air inlet 1124 and / or the air outlet 1126, the through area between the air inlet 1124 and / or the air outlet 1126 and the humidification chamber is adjusted, thereby controlling the air volume passing through the air inlet 1124 and / or the air outlet 1126, so as to realize flexible control of the humidification intensity of the humidifier 100 for the surrounding air. Specifically, when it is necessary to increase the humidification intensity of the humidifier 100 on the surrounding air, the through area between the air inlet 1124 and / or the air outlet 1126 and the humidification chamber is increased to increase the air volume passing through the air inlet 1124 and / or the air outlet 1126, improve the humidification efficiency of the humidifier 100, and thus improve the humidification intensity of the humidifier 100; when it is necessary to reduce the humidification intensity of the humidifier 100 on the surrounding air, the through area between the air inlet 1124 and / or the air outlet 1126 and the humidification chamber is reduced to reduce the air volume passing through the air inlet 1124 and / or the air outlet 1126, reduce the humidification efficiency of the humidifier 100, and thus reduce the humidification intensity of the humidifier 100. Therefore, the humidifier 100 provided by the present disclosure improves the flexibility of adjusting the air humidity, and compared with the related art, it can meet the different humidity requirements of users and improve the user experience.

[0069] Optionally, combined Figures 3 to 5 As shown, the swing blade assembly 130 includes a swing blade motor 1310 and a swing blade 1320. The swing blade motor 1310 is disposed on the housing 110 near the air inlet 1124 and / or the air outlet 1126. The swing blade 1320 is connected to the output end of the swing blade motor 1310, and the swing blade motor 1310 is used to drive the swing blade 1320 to rotate relative to the housing 110 to adjust the through area between the air inlet 1124 and / or the air outlet 1126 and the humidification chamber.

[0070] In this embodiment, the swing blade assembly 130 includes a swing blade motor 1310 and a swing blade 1320. The swing blade motor 1310 is a power device, which is arranged at the housing 110 near the air inlet 1124 and / or the air outlet 1126, and is used to drive the swing blade 1320 to rotate relative to the housing 110. In the process of the swing blade 1320 rotating relative to the housing 110, as the rotation angle of the swing blade 1320 changes, the through area between the air inlet 1124 and / or the air outlet 1126 and the humidification chamber changes, so as to adjust the opening of the air inlet 1124 and / or the air outlet 1126, thereby adjusting the speed and flow rate of air flowing through the air inlet 1124 and / or the air outlet 1126. By flexibly adjusting the opening of the air inlet 1124 and / or the air outlet 1126, the speed and flow rate of the air flowing through the air inlet 1124 and / or the air outlet 1126 are controlled, so that the humidifier 100 can flexibly adjust the air volume according to different environments and / or user needs to achieve the best humidification effect and enhance the user experience.

[0071] Optionally, combined Figures 3 to 5 As shown, the box body 110 includes a box body 1110 and a cover body 1120. The box body 1110 includes a water storage chamber 1112 for storing water. The cover body 1120 is arranged on the box body 1110, and the cover body 1120 includes a humidification chamber, and the humidification chamber is connected with the water storage chamber 1112. Among them, the air inlet 1124 and the air outlet 1126 are located on the cover body 1120. The humidification mechanism 120 is arranged on the box body 1110, and the humidification mechanism 120 is partially located in the water storage chamber 1112, and the part of the humidification mechanism 120 protruding from the water storage chamber 1112 is located in the humidification chamber. The swing blade assembly 130 is arranged on the cover body 1120, and is located at the air inlet 1124 and / or the air outlet 1126.

[0072] In this embodiment, the box body 1110 includes a water storage chamber 1112 for storing water to ensure a stable water source. The humidification mechanism 120 is partially located in the water storage chamber 1112, and the part of the humidification mechanism 120 protruding from the water storage chamber 1112 is located in the humidification chamber, and the humidification chamber is connected with the water storage chamber 1112, so that the humidification mechanism 120 can directly extract water from the water storage chamber 1112 to humidify the air flowing through the humidification chamber. The through design of the humidification chamber and the water storage chamber 1112 enables the humidification mechanism 120 to perform humidification more efficiently, thereby improving the humidification efficiency of the humidifier 100.

[0073] Optionally, combined Figures 1 to 5 As shown, the humidifier 100 further includes a heat preservation pad 140. The heat preservation pad 140 is arranged on the peripheral side of the box body 110.

[0074] In this embodiment, a heat preservation pad 140 is provided around the box 110 to reduce the heat loss inside the box 110 and maintain the temperature inside the box 110 stable. In winter or when the temperature is low, the water stored in the water storage chamber 1112 is easy to condense or even freeze, thereby affecting the humidification effect and service life of the humidifier 100. The heat preservation pad 140 can effectively maintain the temperature of the box 110 to avoid the condensation or even freezing of the water in the water storage chamber 1112. At the same time, by maintaining the temperature inside the box 110 stable, especially the stability of the water temperature in the water storage chamber 1112, it helps the humidification mechanism 120 to more easily convert water into water vapor, thereby further improving the humidification effect of the humidifier 100. In addition, the heat preservation pad 140 can also reduce the stress caused by temperature changes inside the humidifier 100, reduce the risk of damage to the various components of the humidifier 100, and thus extend the service life of the humidifier 100.

[0075] Furthermore, the thickness of the thermal insulation pad 140 is 5 mm (millimeter).

[0076] In this embodiment, the thickness of the heat-insulating pad 140 is limited. By limiting the thickness of the heat-insulating pad 140 to 5 mm, the heat-insulating pad 140 can provide sufficient heat-insulating effect while not being too heavy and occupying too much volume of the humidifier 100, thereby increasing the weight or volume of the humidifier 100.

[0077] Optionally, combined Figure 1 , Figure 3 and Figure 5 As shown, the humidifier 100 further includes a water level detection device 150 . The water level detection device 150 is disposed in the box body 1110 , located in the box body 1110 near the air outlet 1126 , and is used to detect the water level in the water storage chamber 1112 .

[0078] In this embodiment, by arranging a water level detection device 150 in the water storage chamber 1112, the water level in the water storage chamber 1112 is monitored in real time to ensure that the humidifier 100 always operates at a suitable water level, and to avoid the humidifier 100 from operating failures due to lack of water or full water. In addition, since the air flows from the air inlet 1124 to the air outlet 1126, under the influence of the air flow, the water level in the water storage chamber 1112 near the air outlet 1126 is higher. By arranging the water level detection device 150 near the air outlet 1126 in the box body 1110, the water level detection device 150 is arranged on the side with a higher water level, thereby improving the accuracy of water level monitoring, so as to warn the user in advance to perform water addition or drainage operations. Specifically, by arranging the water level detection device 150 on the side with a higher water level, it is possible to respond more quickly to changes in the water level in the water storage chamber 1112 to avoid false alarms or missed alarms. When the water level detection device 150 detects that the water level in the water storage chamber 1112 is close to the upper limit of the water level, the water level detection device 150 sends a water level upper limit warning signal to remind the user to drain the water in advance to prevent the water from overflowing. Similarly, when the water level detection device 150 detects that the water level in the water storage chamber 1112 is close to the lower limit of the water level, the water level detection device 150 sends a water level lower limit warning signal to remind the user to add water in advance to prevent the humidifier 100 from stopping working due to lack of water.

[0079] Optionally, combined Figure 1 , Figure 3 and Figure 5 As shown, the water level detection device 150 includes a first float 1510 and a second float 1520 , and the first float 1510 and the second float 1520 are spaced apart and located in the water storage chamber 1112 .

[0080] In this embodiment, two floats, a first float 1510 and a second float 1520, are used as the water level detection device 150. When the water level in the water storage chamber 1112 rises or falls, the two floats will move accordingly, and the height of the water level can be accurately determined by judging the position change of the two floats. By using two floats as the water level detection device 150, it is possible to effectively avoid misjudgment of the water level due to a single float being stuck, damaged, etc., thereby improving the reliability of the water level detection device 150.

[0081] Further, along the height direction of the box body 110 , the setting height of the first float 1510 is lower than the setting height of the second float 1520 .

[0082] In this embodiment, the setting height of the first float 1510 is limited to be lower than the setting height of the second float 1520, so as to further improve the flexibility of the humidifier 100 in regulating the air humidity. Specifically, when it is necessary to improve the humidification efficiency and humidification intensity of the humidifier 100, the water level in the water storage chamber 1112 is controlled to be maintained at the height of the second float 1520, so that the water level in the water storage chamber 1112 is maintained at a high water level, and the immersion depth of the humidification mechanism 120 is increased, thereby improving the humidification efficiency and humidification intensity of the humidification mechanism 120 when performing humidification work. When it is necessary to reduce the humidification efficiency and humidification intensity of the humidifier 100, the water level in the water storage chamber 1112 is controlled to be maintained at the height of the first float 1510, so that the water level in the water storage chamber 1112 is maintained at a low water level, and the immersion depth of the humidification mechanism 120 is reduced, thereby reducing the humidification efficiency and humidification intensity of the humidification mechanism 120 when performing humidification work.

[0083] Optionally, combined Figure 5 As shown, the box body 1110 further includes a water inlet 1114. The humidifier 100 further includes a water inlet control valve 160 and a water inlet pipeline 170.

Among them, the water inlet pipeline 170 connects the water inlet 1114 and the water storage chamber 1112, and is used to guide water from the water inlet 1114 to flow into the water storage chamber 1112, providing a continuous water source for the humidifier 100. The water inlet control valve 160 is arranged on the water inlet pipeline 170, and is used to control the amount of water flowing from the water inlet 1114 to the water storage chamber 1112 by adjusting the opening of the water inlet control valve 160 to meet the different water requirements of the humidifier 100.

The solenoid valve 1620 is used to control the flow state of water in the water inlet pipeline 170, and the water flow rate is adjusted by adjusting the opening of the solenoid valve 1620. The pressure reducing valve 1610 is used to reduce the water pressure entering the water inlet pipeline 170 to ensure that water can flow into the humidifier 100 smoothly and safely.

The water outlet pipeline 190 connects the water outlet 1116 and the water storage chamber 1112, and is used to guide water from the water storage chamber 1112 to the water outlet 1116, so that the humidifier 100 can discharge excess water. The water pump 180 is arranged on the water outlet pipeline 190, and the water pump 180 is used as a power source to provide the necessary pressure for the water flow so that it can pass through the water outlet pipeline 190 smoothly.

[0089] Optionally, combined Figures 5 to 7 As shown, the humidification mechanism 120 includes a driving motor 1210 and a rotating wheel assembly 1220.

The rotating wheel assembly 1220 is connected to the output end of the driving motor 1210, and the driving motor 1210 is used to drive the rotating wheel assembly 1220 to rotate relative to the housing 110.

[0090] In this embodiment, the wheel assembly 1220 is connected to the output end of the driving motor 1210. The driving motor 1210 transmits power to the wheel assembly 1220 through the output end, thereby driving the wheel assembly 1220 to rotate relative to the housing 110. The wheel assembly 1220 absorbs moisture from the water storage chamber 1112 through rotation, and distributes the moisture into the air through the centrifugal effect of the rotation of the wheel, thereby humidifying the air in the humidification chamber.

[0091] Optionally, combined Figure 6 and Figure 7As shown, the wheel assembly 1220 includes a first end cap 1222, a second end cap 1224, an inner frame 1228, an outer frame 1230 and a humidifying grid.

The inner frame 1228 is arranged between the first end cap 1222 and the second end cap 1224 and extends from the first end cap 1222 toward the second end cap 1224. The two ends of the inner frame 1228 are respectively connected to the first end cap 1222 and the second end cap 1224. The outer frame 1230 is nested in the inner frame 1228 and is connected to both the first end cap 1222 and the second end cap 1224. A receiving cavity is defined between the outer frame 1230 and the inner frame 1228. The humidifying grid is arranged around the inner frame 1228 and filled in the receiving cavity. Among them, the outer frame 1230 is provided with a plurality of through holes so that water can flow into the humidifying grid through the through holes. A rotating shaft mounting structure 1226 is provided at the center of the end surface of the first end cover 1222 and / or the center of the end surface of the second end cover 1224 , and the rotating shaft mounting structure 1226 is connected to the output end of the driving device.

[0092] In this embodiment, by providing an inner frame 1228 and providing a receiving cavity between the inner frame 1228 and the outer frame 1230, the humidifying grid can be wrapped around the inner frame 1228 and filled in the receiving cavity, and the humidifying grid is fixed by the inner frame 1228 and the outer frame 1230. By providing a plurality of through holes in the outer frame 1230, when the wheel assembly 1220 used for the humidifier 100 contacts water, the water can flow into the humidifying grid in the outer frame 1230 through the through holes on the outer frame 1230. When the wheel assembly 1220 rotates, the humidifying grid can absorb water on the one hand, so that the water rotates with the humidifying grid, and on the other hand, when the water moves on the humidifying grid, the humidifying grid can break up the liquid water into gaseous water to humidify the air. By providing a rotating shaft mounting structure 1226 at the end surface center of the first end cover 1222 and / or the end surface center of the second end cover 1224, the driving device can be connected to the first end cover 1222 and the second end cover 1224 through the output shaft. The driving device can drive the first end cover 1222 and the second end cover 1224 to rotate around their centers, thereby driving the inner skeleton 1228 and the outer skeleton 1230 to rotate, thereby driving the wheel assembly 1220 to rotate.

[0093] Furthermore, part of the humidifying grid is located in the water storage chamber 1112, and part of the humidifying grid protruding from the water storage chamber 1112 is located in the humidifying chamber.

[0094] In this embodiment, the humidification grid is partially located in the water storage chamber 1112 and immersed in water. When the driving device drives the wheel assembly 1220 to rotate in the box 110, the humidification grid drives the water to rotate and breaks up the liquid water to form gaseous water, and then uses the air flow to drive the gaseous water to mix with the air to achieve air humidification.
