Description

Technical Field

[0001] This utility model belongs to the field of refrigerator air duct technology, and in particular relates to a refrigerator air duct component. Background Technology

[0002] Refrigerator ducts are an important component of the refrigerator's air duct system. They are pipe systems inside the refrigerator used to transport cold air, and are usually installed between the freezer and refrigerator compartments, serving to connect the two compartments.

[0003] Currently, due to the high humidity inside the refrigerator and the frequent opening and closing of the refrigerator door, the internal moisture is heavy. When the moisture enters the air duct, it will frost up under the influence of the cold air, which not only affects the normal use of the air duct, but also makes subsequent cleaning more troublesome.

[0004] To address the aforementioned problems, this application proposes a refrigerator air duct assembly. Utility Model Content

[0005] The purpose of this invention is to provide a refrigerator air duct assembly that solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a refrigerator air duct assembly, including an air duct and an air inlet above it and an air outlet below it;

[0008] The dehumidification unit is located in front of the air inlet and has a first and second mesh inside. The interlayer between the first and second mesh is filled with dehumidifying particles.

[0009] The dehumidification unit is equipped with an elastic telescopic rod at the entrance to push the first partition net and adjust the size of the interlayer space in real time.

[0010] The dehumidification unit is provided with a base at the bottom and a water collection chamber inside it. The upper end of the water collection chamber is provided with a dense mesh plate mechanism.

[0011] The air duct has a drain pipe inside that connects to the water collection chamber.

[0012] Furthermore, gauze is provided behind the first mesh to seal and dehumidify the particles.

[0013] Furthermore, a filling hole is provided inside the upper end of the dehumidification unit, and a sealing plug is installed inside it.

[0014] Furthermore, the water collection cavity is provided with a guide slope that is higher at the front and lower at the back, and a positioning groove is provided near the rear end.

[0015] Furthermore, the rear end of the base has a hole perpendicular to the axis of the positioning groove, extending to the bottom of the dehumidification unit, and a plug tube is provided at the rear of the base to connect to the bottom of the dehumidification unit.

[0016] Furthermore, the dehumidification unit has protruding supports on the inner sides of both the upper and lower ends for mounting elastic telescopic rods.

[0017] Furthermore, a water-locking paper is provided in front of the second mesh to prevent moisture from entering the air duct.

[0018] This utility model has the following beneficial effects:

[0019] This invention fills the space between the first and second partitions with calcium chloride particles, which can absorb the moisture carried by the air as it passes through. This allows the air to enter the duct after dehumidification, thus avoiding frost formation caused by moisture inside the duct. It also eliminates the problem of inconvenient cleaning after frost forms.

[0020] This invention allows calcium chloride particles to absorb moisture and turn into water, which is then collected inside the positioning groove and discharged outside the refrigerator through the drain pipe. This effectively prevents frost or ice from forming inside the refrigerator, making the dehumidification operation stable and worry-free.

[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] Please see Figure 1-4 As shown, this utility model is a refrigerator air duct assembly, including an air duct 1 and an air inlet above it and an air outlet 3 below it.

[0032] The dehumidification unit 2 is located in front of the air inlet and has a first mesh 4 and a second mesh 6 inside. The interlayer between the first mesh 4 and the second mesh 6 is filled with dehumidifying particles. The dehumidifying particles are calcium chloride, which condenses into water after absorbing moisture, and at the same time, their own volume is reduced accordingly.

[0033] At the entrance of the dehumidification unit 2, an elastic telescopic rod 13 is provided to push the first partition 4 and adjust the size of the interlayer space in real time so that the reduced dehumidification particles still fill the interlayer space.

[0034] The bottom of the dehumidification unit 2 is provided with a base 5, and a water collection chamber 10 is provided inside it. The upper end of the water collection chamber 10 is provided with a dense mesh plate mechanism. The upper part of the water collection chamber 10 is connected to the interlayer space, and the dense mesh plate is used to prevent dehumidification particles from entering the water collection chamber 10.

[0035] The air duct 1 is equipped with a drain pipe 7, and the internal transmission channel is connected to the water collection chamber 10;

[0036] Preferably, a gauze 8 is provided behind the first partition 4 to block the dehumidifying particles, so as to prevent the dehumidifying particles from overflowing out of the mesh of the first partition 4 after their volume decreases.

[0037] Preferably, the upper end of the dehumidification unit 2 has a filling hole and a sealing plug 9 is installed inside it. When the dehumidification particles are consumed, the dehumidification unit 2 can be removed and refilled through the filling hole.

[0038] Preferably, the water collection chamber 10 has a guide slope 11 that is higher at the front and lower at the back, and a positioning groove 14 is provided near the rear end, so that all the collected water is gathered in the positioning groove 14, which facilitates the water flow to be discharged outward.

[0039] Preferably, the rear end of the base 5 has a hole perpendicular to the axis of the positioning groove 14, extending to the bottom of the dehumidification unit 2, and a plug tube 15 is provided at the rear of the base 5 to connect to the hole at the bottom of the dehumidification unit 2. The hole at the bottom of the dehumidification unit 2 is connected to the drain pipe 7.

[0040] Preferably, the upper and lower ends of the dehumidification unit 2 are provided with protruding supports 12 for installing elastic telescopic rods 13, which are distributed horizontally at equal intervals inside the supports 12.

[0041] Preferably, a water-locking paper 16 is provided in front of the second partition 6 to prevent moisture from entering the air duct 1.

[0042] Understandably, this invention can dehumidify the air entering the air duct inside the refrigerator, thereby preventing frost and ice buildup in the air duct, ensuring stable operation, and eliminating concerns about subsequent cleaning hassles.

[0043] A specific application of the operation process in this embodiment is as follows: First, the dehumidification unit 2 is placed at the front end of the air inlet of the air duct 1. Then, when air enters the refrigerator, the calcium chloride particles filled between the first mesh 4 and the second mesh 6 adsorb water vapor, condense into water droplets and fall into the water collection chamber 10. Then, under the guidance of the guide slope 11, the water droplets gather in the positioning groove 14 and are finally discharged from the refrigerator by the drain pipe 7. During the process of calcium chloride adsorbing humid air, as the volume decreases, the elastic telescopic rod 13 pushes the first mesh 4, so that the filled particles always fill the interlayer space to ensure the adsorption effect. This can prevent moisture from entering the air duct 1 and causing frost or ice.
