[0001] This utility model relates to the field of air conditioning technology, and in particular to a fresh air humidification device suitable for cold regions. Background Technology

[0002] Winters in northern my country are cold and dry, and indoor spaces are often enclosed, necessitating the introduction of fresh air into buildings via heat recovery. Due to low humidity in northern winters, humidification of the introduced fresh air is also necessary. Publication number CN 118009425 A proposes a control method and fresh air unit for a fresh air humidification system suitable for cold regions. The humidification module is located on the air supply duct, and the control system humidifies the introduced fresh air. This method can humidify fresh air directly entering the room, but it increases the space requirements for the ceiling, limiting its application to small residential buildings. Summary of the Invention

[0003] To address the aforementioned issues, this invention proposes a fresh air humidification device suitable for cold regions. The humidification device is placed inside a fresh air heat recovery unit, and when the unit is turned on, it humidifies the fresh air entering the room.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A fresh air humidification device suitable for cold regions includes a first water tank, a water flow channel, a water inlet, a drain outlet, a humidification grille, a second water tank, and a fixing component. The humidification grille includes a first humidification material and a second humidification material.

[0006] The first water tank is located at the top of the device and is a stainless steel concave groove. Several circular holes are provided on the bottom plane of the inner side of the first water tank. The circular holes are evenly arranged along the width and length of the first water tank. A water inlet is provided on the right side wall of the first water tank.

[0007] Furthermore, the lower part of the first water tank is provided with a water flow channel. The water flow channel is elongated and located directly below the circular hole on the bottom plane of the first water tank. The water flow channel is made of metal and is welded to the outer side of the bottom of the first water tank, and is evenly distributed parallel to the width direction of the first water tank.

[0008] The bottom of the water flow channel is provided with a narrow slit along the width direction of the first water tank. The upper part of the first humidifying material and the second humidifying material are connected to the narrow slit of the first water tank. The width of the narrow slit is slightly larger than the thickness of the first humidifying material and the second humidifying material. The first humidifying material and the second humidifying material are made of non-woven fabric or other materials with good water absorption properties.

[0009] Furthermore, the left, right, and lower edges of the first and second humidifying materials are compacted.

[0010] The lower parts of the first and second humidifying materials are fixed to the bottom plane of the inner side of the second water tank by fasteners. The fasteners are made of metal and the fixing method is welding.

[0011] Furthermore, several humidifying grids composed of the first humidifying material and the second humidifying material are evenly arranged along the length of the first water tank and parallel to the width of the first water tank. The humidifying grids and the circular holes on the bottom plane of the inner side of the first water tank are in the same vertical direction.

[0012] The second water tank is located at the bottom of the device and is a stainless steel concave groove. The depth of the groove on the left side of the second water tank is less than that on the right side, and a drain outlet is provided on the right side wall near the bottom of the groove.

[0013] The beneficial effects of this invention are that the humidification device is installed inside the fresh air heat recovery unit, and the humidification device can be flexibly set according to the size of the fresh air heat recovery unit. Moreover, during the humidification process, the water flow is mainly distributed inside the humidification material to wet the humidification material, and no water flow is generated on the outer surface of the humidification material, thus avoiding the airflow from bringing water droplets into the room.

Detailed Implementation

[0019] This invention provides a fresh air humidification device suitable for cold regions, including a water tank and a humidification grille.

[0020] The embodiments of this utility model will be further described in detail below through examples and with reference to the accompanying drawings.

[0021] A fresh air humidification device suitable for cold regions includes a first water tank 1, a water inlet 3, and a water flow channel 2. The first water tank 1, located at the top of the device, is a stainless steel concave groove that serves as a container for tap water inflow and storage. Tap water flows into the first water tank 1 through the water inlet 3 located on the right side wall of the first water tank 1. Several circular holes are evenly arranged along the width and length of the first water tank 1 on the bottom inner surface of the first water tank 1, and water flows into the water flow channel 2 through these circular holes.

[0022] Water flow channel 2 is located at the lower part of the first water tank 1. Water flow channel 2 is elongated and located directly below the circular hole on the bottom plane of the inner side of the first water tank 1. Water flow channel 2 is made of metal and is welded to the outer side of the bottom of the first water tank 1. It is evenly arranged parallel to the width direction of the first water tank 1. The arrangement direction and length of water flow channel 2 are consistent with the arrangement direction and length of the circular hole.

[0023] A narrow slit is provided at the bottom of the water flow channel 2 along the width direction of the first water tank 1. The upper part of the first humidifying material 8 and the second humidifying material 9 are connected to the narrow slit of the first water tank 1. The width of the narrow slit is slightly larger than the thickness of the first humidifying material 8 and the second humidifying material 9. The materials of the first humidifying material 8 and the second humidifying material 9 can be non-woven fabric or other materials with good water absorption. The left, right, and lower edges of the first humidifying material 8 and the second humidifying material 9 are compacted to ensure that the first humidifying material 8 and the second humidifying material 9 are tightly attached to each other on the left, right, and lower sides, and do not separate, so that the water flow is always between the first humidifying material 8 and the second humidifying material 9, and the water flow does not flow outward.

[0024] The lower parts of the first humidifying material 8 and the second humidifying material 9 are fixed to the bottom plane of the inner side of the second water tank 6 by a fastener 7. The fastener 7 is made of metal and is fixed by welding.

[0025] A number of humidifying grids 5, composed of the first humidifying material 8 and the second humidifying material 9, are evenly arranged along the length of the first water tank 1 and parallel to the width of the first water tank 1. The humidifying grids 5 and the circular holes on the bottom plane of the inner side of the first water tank 1 are in the same vertical direction, and water can flow directly into the humidifying grids 5 from the circular holes.

[0026] The second water tank 6 is located at the bottom of the device and is a stainless steel concave groove. It can collect water droplets that are not fully utilized by the humidifying grille 5 and that seep out from the bottom of the humidifying grille 5. The depth of the left side of the second water tank 6 is less than the height of the right side. A drain outlet 4 is provided on the right side wall near the bottom of the groove. The water in the second water tank 6 is discharged through the drain outlet 4 to the floor drain in the kitchen or bathroom under the action of gravity.

[0027] The specific operation mode is illustrated by taking the fresh air heat recovery unit 10 as an example:

[0028] When the fresh air heat recovery unit 10 is manually turned on, the fresh air fan 11 is started, and the outdoor fresh air enters the fresh air heat recovery unit 10 through the fresh air vent 12.

[0029] Tap water from the kitchen or bathroom flows into the first sink 1 from the inlet 3. The water flowing into the first sink 1 enters the water channel 2 at the bottom of the first sink 1 through the circular hole at the bottom of the first sink 1.

[0030] Water flows into the humidification grille 5, which is composed of the first humidifying material 8 and the second humidifying material 9, through the water flow channel 2. Due to the strong water absorption of the first humidifying material 8 and the second humidifying material 9, the water can quickly and evenly wet the first humidifying material 8 and the second humidifying material 9. Excess water flows into the second water tank 6. Under the action of gravity, the water flows into the kitchen or bathroom floor drain through the drain outlet 4 of the second water tank 6.

[0031] The air blown out by the fresh air fan 11 passes through the humidifying grille 5, forming a moist airflow that is then delivered into the room through the air outlet 13, thus achieving fresh air humidification.

[0032] A fresh air humidification device suitable for cold regions has the advantage that the size of the device can be flexibly set according to the structure of the fresh air heat recovery unit 10, so as to achieve uniform water distribution and avoid the supply airflow from bringing water droplets into the room.

[0033] The above specific embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
