Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0025] The humidifier drip tray provided in this application embodiment, such as Figure 1 and Figure 2 As shown, it includes: a main body 100, having a water storage area 110 and a drainage area 120, the drainage area 120 and the water storage area 110 being connected by an overflow structure 160, the water storage area 110 being configured to store water and house a wet membrane 200, and the drainage area 120 being configured to drain water outwards.

[0026] This water tray is used in a humidifier. The water tray has a water storage area 110 and a drainage area 120, which are connected by an overflow structure 160. The water storage area 110 is used to store water, and the wet membrane 200 is placed in the water storage area 110. When the water level in the water storage area 110 reaches the overflow structure 160, the water in the water storage area 110 flows to the drainage area 120 through the overflow structure 160 to prevent water from overflowing from the water storage area 110 to the main body 100. The drainage area 120 is used to drain water. This water tray integrates the functions of a water tank and a wet membrane fixing device in related technologies. Compared with the combined structure of water tray, water tank and wet membrane fixing device in related technologies, this water tray has a smaller height and occupies less space. Therefore, the humidifier made with this water tray has a simpler structure, a smaller height, and is more conducive to installation in indoor ceilings.

[0027] In some examples, such as Figure 1 and Figure 2As shown, the main body 100 also has a support structure 130, which is located inside the water storage area 110 and configured to hold the wet membrane 200. The wet membrane 200 is placed on the support structure 130, thus fixing the wet membrane 200 inside the water storage area 110. This water receiving tray can be manufactured by injection molding. Compared with the combined structure of water receiving tray, water tank, and wet membrane fixing device in related technologies, this water receiving tray (i.e., the water receiving tray of this application) is not only simpler to manufacture, but also has lower cost and occupies less space.

[0028] In some examples, such as Figure 1 and Figure 2 As shown, the main body 100 also has a drainage structure 141, which is located between the support structure 130 and the inner bottom surface of the water storage area 110 and is configured to drain water into the area outside the drainage structure 141 within the water storage area 110. The wet membrane 200 is placed on the support structure 130 and spaced apart from the drainage structure 141. Water flowing down from the wet membrane 200 flows onto the drainage structure 141, which then drains the water falling onto it into the area outside the drainage structure 141 within the water storage area 110. This accelerates the drainage of water from the wet membrane 200 and prevents the humidification efficiency of the wet membrane 200 from decreasing due to poor drainage.

[0029] In some embodiments, such as Figure 1 and Figure 2 As shown, the inner bottom surface of the water storage area 110 is provided with a first protrusion 140 and a plurality of supporting ribs 131. The first protrusion 140 is arranged along a first direction (such as the left-right direction), and in a second direction (i.e., from back to front), the platform of the first protrusion 140 extends obliquely away from the inner bottom surface of the water storage area 110 (i.e., from back to front and upward) (at this time, the platform of the first protrusion 140 is an inclined surface or a curved surface). A plurality of supporting ribs 131 are provided on the platform of the first protrusion 140 and are spaced apart in the first direction. The second direction is the air outlet direction of the humidifier (e.g., the air outlet direction is from back to front, the front side of the air outlet direction is the downstream side, and the rear side of the air outlet direction is the upstream side). The first direction (left-right direction), the second direction (from back to front direction) and the depth direction of the water storage area 110 (such as the up-down direction) intersect each other. The support structure 130 includes a plurality of supporting ribs 131, and the drainage structure 141 includes the platform of the first protrusion 140.

[0030] The wet membrane 200 is placed on the support rib 131, so that the wet membrane 200 is spaced from the platform of the first protrusion 140. This facilitates the rapid flow of water from the wet membrane 200 to the platform of the first protrusion 140. The platform of the first protrusion 140 slopes downward from front to back, which further facilitates the flow of water from the platform of the first protrusion 140 to the area behind the first protrusion 140 in the water storage tank. Therefore, this design results in fast water drainage from the wet membrane 200 and high humidification efficiency. The maximum height of the support rib 131 is set to be no less than 3mm.

[0031] In some embodiments, such as Figure 1 and Figure 2 As shown, the inner bottom surface of the water storage area 110 is also provided with a second protrusion 132 and two third protrusions 133. The second protrusion 132 is arranged along the first direction and is located upstream of the first protrusion 140 in the second direction. The two third protrusions 133 are spaced apart in the first direction and are located downstream (i.e., rear) of the second protrusion 132 in the second direction. In the first direction (i.e., left-right direction), the first protrusion 140 is located between the two third protrusions 133. The first protrusion 140, the second protrusion 132 and the two third protrusions 133 are connected. The support structure 130 also includes the second protrusion 132 and the two third protrusions 133.

[0032] After the wet membrane 200 is placed on the support structure 130, the bottom surface of the wet membrane 200 abuts against the upper surface of the multiple support ribs 131, the platform surface of the second protrusion 132, and the platform surface of the two third protrusions 133. In this way, there will be no air leakage between the wet membrane 200 and the support structure 130 (that is, the air jet blown out by the humidifier will basically not be blown forward between the wet membrane 200 and the support structure 130).

[0033] like Figure 1 and Figure 2 As shown, the angle A between the opposite sides of the two third protrusions 133 and the platform of the first protrusion 140 is set to 100 degrees to 150 degrees. This makes it easier for water flowing from the wet film 200 to the third protrusions 133 to flow along the side of the third protrusions 133 facing the first protrusion 140 to the platform of the first protrusion 140, which also accelerates the drainage of water from the wet film 200. The angle B between the inner bottom surface of the water storage area 110 and the platform of the first protrusion 140 is set to 120 degrees to 160 degrees, which improves the water drainage effect of the platform of the first protrusion 140. The platforms of the two third protrusions 133 are provided with limiting parts 134 for limiting the wet film 200 (e.g., Figure 1As shown, the wet membrane 200 is limited by the limiting part 134 to prevent horizontal movement of the wet membrane 200 on the support structure 130, thus effectively improving the fixation stability of the wet membrane 200 on the support structure 130. The limiting part 134 is configured as a limiting rib, which has a simple structure, is easy to manufacture, and provides good limiting effect on the wet membrane 200.

[0034] In some examples, such as Figure 1 and Figure 2 As shown, the main body 100 also has a water-proof structure 150, which is located inside the water storage area 110 and downstream (i.e. front) of the support structure 130 in the air outlet direction of the humidifier (i.e., from back to front), further improving the space utilization of the water tray.

[0035] The airflow from the humidifier passes through the wet membrane 200, potentially carrying small water droplets forward. These droplets, carried forward by the airflow, will move downwards under gravity, eventually falling into the room or onto the ceiling, causing water droplets to condense on the ceiling. This solution incorporates a water-blocking structure 150 on the front of the support structure 130. This structure collects the small water droplets (carried forward by the airflow) that are moving downwards under gravity and allows them to flow back into the water storage tank, preventing the water droplets from being blown into the room or falling onto the ceiling.

[0036] In some embodiments, such as Figure 1 As shown, the anti-blowing structure 150 is a water receiving trough, and the water storage area 110 is a water storage trough. The water receiving trough is provided with a connecting port, and the water receiving trough and the water storage trough are connected through the connecting port. The inner bottom surface of the water receiving trough is a flow guiding surface, which is set to guide water to the connecting port to ensure that the water in the water receiving trough flows back to the water storage trough quickly from the connecting port.

[0037] Among them, such as Figure 1 As shown, the left end of the water receiving trough is open, forming a connecting opening, while the right end is closed. The guide surface is located above the inner bottom surface of the water storage area 110 and extends downwards from right to left. Alternatively, the guide surface can be a slope or a curved surface. Alternatively, the depth of the water storage area 110 can be set to 30mm~50mm, and the inner bottom surface of the water receiving trough can be higher than the inner bottom surface of the area outside the water receiving trough, overflow structure 160, and support structure 130. Alternatively, the dimension of the water storage trough in the front-to-back direction can be C, and the dimension of the water receiving trough in the front-to-back direction can be approximately C / 6. In this scheme, when the wet film 100 reaches the critical point of water blowing, the humidifier's airflow can be further increased by 15%, thus preventing water blowing into the room and water bubbling on the ceiling, thereby improving the humidification efficiency of the humidifier.

[0038] In some examples, such as Figure 1As shown, the drainage area 120 is a drainage trough, which is located behind the water storage tank. There is a common wall between the drainage trough and the water storage tank, and the overflow structure 160 is located at the end of the common wall away from the inner bottom surface of the water storage tank.

[0039] The humidifier provided in the embodiments of this application, such as Figure 3 and Figure 4 As shown, it includes: a water receiving tray for a humidifier as described in any of the above embodiments; a wet membrane 200, which is placed in a water storage area 110; a spray head 300, which is located on the side of the wet membrane 200 facing away from the main body 100, with the spray nozzle of the spray head 300 facing the wet membrane 200; and a water pump 400, which is configured to supply water from the water storage area 110 to the spray head 300.

[0040] In this humidifier, the water pump 400 supplies water from the water storage area 110 to the spray head 300. The spray nozzles of the spray head 300 spray water towards the wet film 200, thereby humidifying the wet film 200. The water flowing down from the wet film 200 falls back into the water storage area 110, realizing the recycling of water in the water storage area 110. The water receiving tray of this application integrates the functions of the combined structure of water receiving tray, water tank and wet film fixing device in related technologies. Compared with the combined structure of water receiving tray, water tank and wet film fixing device in related technologies, the height of the water receiving tray of this application occupies less space. Therefore, the humidifier made with this water receiving tray has a simpler structure, a smaller height, and is more conducive to installation in indoor ceilings.

[0041] In some embodiments, such as Figure 4 As shown, the humidifier also includes: a control valve 500, which has a first interface, a second interface and a third interface, and is configured to connect the first interface to at most one of the second interface and the third interface by switching the position of the valve core; the inlet of the water pump 400 is connected to the water storage area 110; the first interface is connected to the outlet of the water pump 400; the second interface is connected to the drainage area 120; and the third interface is connected to the inlet of the spray head 300.

[0042] During humidification, the first interface is connected to the third interface, enabling the water pump 400 to continuously supply water to the spray head 300. When it is necessary to drain the water in the water storage area 110, the first interface is connected to the second interface, enabling the water pump 400 to supply water from the water storage area 110 to the drainage area 120. The water supplied to the drainage area 120 is finally discharged to the outside from the drain outlet of the drainage area 120 (compared with related technologies, this application no longer requires an additional water pump or switch valve at the drain outlet). Because there is an overflow structure 160 between the water storage area 110 and the drainage area 120, even if the water pump 400 and / or control valve 500 are damaged, the water tray will not overflow due to excessive water addition. Excess water will flow from the overflow structure 160 to the drainage area 120 and then be discharged to the outside from the drain outlet of the drainage area 120. This application achieves the functions of circulating water and drainage through the cooperation of a water pump 400 and a control valve 500, resulting in a simpler structure and lower cost. Among them, the control valve 500 is set as a three-way valve.

[0043] In some embodiments, such as Figure 3 As shown, the humidifier also includes a fan 600, which is located upstream of the wet membrane 200 in the second direction. The air outlet of the fan 600 faces forward and towards the rear side of the wet membrane 200, and the air outlet direction of the fan 600 is from back to front. The air jet blown out by the fan 600 passes through the wet membrane 200 and is then blown into the room to humidify the indoor environment.

[0044] In some embodiments, such as Figure 4 As shown, the humidifier also includes: a pressure reducing valve 700, a solenoid valve 800, and a water level detection device 900. The inlet of the pressure reducing valve 700 is connected to the tap water source, and the outlet is connected to the inlet of the solenoid valve 800. The outlet of the solenoid valve 800 is connected to the water storage area 110.

[0045] When the water level detection device 900 detects that the water level in the water storage area 110 has reached the minimum water level, the solenoid valve 800 opens and water is added to the water storage area 110 through tap water.

[0046] When the water level detection device 900 detects that the water level in the water storage area 110 has reached the maximum water level, the solenoid valve 800 closes to stop adding water to the water storage area 110.

[0047] In summary, the technical solution provided in this application embodiment allows the water tray to be used in a humidifier. The water tray has a water storage area and a drainage area, which are connected by an overflow structure. The water storage area is used to store water, and the wet membrane is placed in the water storage area. When the water level in the water storage area reaches the overflow structure, the water in the water storage area flows to the drainage area through the overflow structure. The drainage area is used to drain water outwards, preventing water from overflowing from the water tray and causing waterlogging in the ceiling. This water tray integrates the functions of a water tank and a wet membrane fixing device in related technologies. Compared with the combined structure of water tray, water tank, and wet membrane fixing device in related technologies, this water tray has a smaller height and occupies less space. Therefore, the humidifier made with this water tray has a simpler structure, a smaller height, and is more conducive to installation in the indoor ceiling.
