Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, and in particular to a humidification device and a refrigerator having the same. Background Technology

[0002] Humidifiers, as key components for improving indoor air humidity, are widely used in household appliances such as air conditioners, air purifiers, and refrigerators. Among them, the humidifier water box, as the core component for water storage and atomization, directly affects atomization efficiency, humidification capacity, and operational stability through its structural design.

[0003] In existing technologies, traditional atomizing components have regular shapes, such as circles, which limit the contact area with devices such as water absorption holes. This results in a low water supply rate, which cannot meet the humidification requirements of large spaces or high humidity scenarios, and users report that the humidification efficiency is low. Utility Model Content

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a humidification device with advantages such as high water output and good humidification effect.

[0005] To achieve the above objectives, a humidification device is provided according to an embodiment of the present invention, comprising: a housing, one side of which has a mist outlet; a humidification water box, which is installed inside the housing; and an atomizing component, which is installed inside the humidification water box facing the mist outlet; characterized in that the humidification water box has a water absorption hole, and the atomizing component passes through the water absorption hole and generates water mist on the side of the water absorption hole facing the mist outlet; wherein the water absorption hole includes a central hole and a serrated portion, the serrated portion is formed at the edge of the central hole and is arranged at intervals along the circumference of the central hole, and the atomizing component passes through the central hole and the serrated portion.

[0006] According to the humidification device of this utility model embodiment, the serrated structure increases the surface area of ​​the water absorption orifice. Because the serrated portion is arranged circumferentially along the central hole, the contact area between the atomizing component and water is increased. This allows the atomizing component to absorb more water, providing a sufficient water source for its subsequent operation. When the atomizing component is working, more water can be atomized into water mist, effectively solving the problem of small spray volume. For example, traditional water absorption orifices may only allow the atomizing component to absorb a limited amount of water, while the serrated structure allows the atomizing component to absorb more water per unit time, enabling it to produce more water mist and thus increasing the water output of the humidification device.

[0007] Therefore, the humidification device according to the embodiments of this utility model has the advantages of high water output and good humidification effect.

[0008] According to some specific embodiments of this utility model, the atomizing component includes: a water-absorbing component, which is disposed through the water-absorbing through hole and adapted to absorb water in the humidifying water box; and an atomizing generator, which is installed on the side of the water-absorbing through hole facing the mist outlet to generate water mist.

[0009] The above technical solution has the following advantages or beneficial effects: Due to the synergistic effect of the water absorption component and the atomizing generator, this humidification device can more efficiently convert water into water mist and release it into the air. The combination of the efficient water absorption capacity of the water absorption component and the uniform atomization capacity of the atomizing generator enables the humidification device to increase air humidity in a shorter time, achieving a better humidification effect.

[0010] According to some specific embodiments of this utility model, the water-absorbing component includes: a water-absorbing column, which passes through the water-absorbing through hole; and a water-absorbing block, which is connected to one end of the water-absorbing column and located on the side of the water-absorbing through hole facing away from the mist outlet.

[0011] The above technical solution has the following advantages or beneficial effects: the water absorption component, through the water absorption block and water absorption column, can provide a stable water supply to the atomizer.

[0012] According to some specific embodiments of this utility model, there are multiple water-absorbing columns and multiple water-absorbing holes. The multiple water-absorbing holes are arranged at intervals along the length direction of the humidifying water box. The water-absorbing columns and the water-absorbing holes are arranged in a one-to-one correspondence. The side of the multiple water-absorbing columns facing away from the mist outlet is connected to the water-absorbing block.

[0013] The above technical solution has the following advantages or beneficial effects: multiple water-absorbing columns and water-absorbing through holes provide multiple channels for water flow, enabling water to flow more smoothly from the water storage chamber to the spray chamber, reducing the resistance of water flow during transmission and improving the transmission efficiency of water flow.

[0014] According to some specific embodiments of the present invention, a sealing ring is constructed on the side of the atomizing generator facing the water absorption hole, and the sealing ring surrounds the water absorption hole and seals with the water absorption hole.

[0015] The above technical solution has the following advantages or beneficial effects: the sealing ring surrounds the water intake hole and seals with the water intake hole, which can effectively prevent water from leaking from the gap between the atomizer and the water intake hole.

[0016] According to some specific embodiments of the present invention, the humidifying water box is provided with a limiting ridge on the side of the water absorption hole facing the mist outlet, and the limiting ridge surrounds the outer periphery of the atomizing generator.

[0017] The above technical solution has the following advantages or beneficial effects: the limiting ridge surrounds the outer periphery of the atomizer, which can ensure that the atomizer can be accurately positioned in the correct position of the water intake hole during installation, and can prevent the atomizer from shifting or tilting during installation, thereby ensuring its alignment and sealing performance with the water intake hole.

[0018] According to some specific embodiments of this utility model, the humidifying water box is divided into a water storage chamber and a spray chamber. The spray chamber is located on the side of the water storage chamber facing the mist outlet, and the water absorption hole is located on the side of the spray chamber away from the mist outlet.

[0019] The above technical solution has the following advantages or beneficial effects: the separation of the water storage chamber and the spray chamber allows the water flow to proceed more orderly from the water storage chamber to the spray chamber. The water is first stored in the water storage chamber, then enters the spray chamber through the water intake hole, and finally reaches the atomizing component. This avoids disorderly water flow within the humidifying water box and reduces water waste.

[0020] According to some specific embodiments of this utility model, the humidifying water box includes: a bottom box, the interior of which is divided into a water storage chamber and a spray chamber, and a water absorption hole is formed inside the bottom box; a box cover, which seals the top surface of the water storage chamber to close the water storage chamber; and a top cover, which covers the box cover and seals the top surface of the bottom box to close the spray chamber; wherein the box cover and the top cover together form a water inlet.

[0021] The above technical solution has the following advantages or beneficial effects: the lid covers the top surface of the water storage cavity, and the top cover covers the lid and seals the top surface of the bottom box. This double-sealed structure can effectively prevent water from leaking out of the water box, and the combination of the lid and the top cover provides a physical seal.

[0022] According to some specific embodiments of the present invention, the bottom box is constructed with a drain outlet, which is located on the side surface of the bottom box opposite to the mist outlet and at the connection between the bottom and the side of the bottom box.

[0023] The above technical solution has the following advantages or beneficial effects: it can drain water directly from the bottom of the humidifying water box, so that the water can be discharged from the lowest point of the humidifying water box, thereby effectively solving the problem that residual water cannot be drained in one go.

[0030] In the description of this utility model, "multiple" means two or more.

[0031] In the description of this utility model, the first feature being "above" or "below" the second feature may include the first and second features being in direct contact, or it may include the first and second features not being in direct contact but being in contact through another feature between them.

[0033] The humidification device 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0034] like Figures 1-10 As shown, the humidification device 1 according to an embodiment of the present invention includes a housing 100, a humidification water box 200, and an atomizing component 300.

[0035] A mist outlet 101 is formed on one side of the housing 100. A humidifying water box 200 is installed inside the housing 100. An atomizing component 300 is installed inside the humidifying water box 200 facing the mist outlet 101. The humidifying water box 200 is constructed with a water intake hole 210, and the atomizing component 300 passes through the water intake hole 210 and generates water mist on the side of the water intake hole 210 facing the mist outlet 101. The water intake hole 210 includes a central hole portion 211 and a serrated portion 212. The serrated portions 212 are formed at the edge of the central hole portion 211 and are arranged at intervals along the circumference of the central hole portion 211. The atomizing component 300 passes through the central hole portion 211 and the serrated portion 212.

[0036] According to the humidifying device 1 of this utility model embodiment, the serrated portion 212 increases the surface area of ​​the water absorption hole 210. Since the serrated portion 212 is arranged circumferentially along the central hole 211, the contact area between the atomizing component 300 and water is increased. This allows the atomizing component 300 to absorb more water, providing sufficient water for its subsequent operation. When the atomizing component 300 is working, more water can be atomized into water mist, effectively solving the problem of small spray volume. For example, a traditional water absorption hole may only allow the atomizing component 300 to absorb a limited amount of water, while the water absorption hole 210 with the serrated portion 212 structure allows the atomizing component 300 to absorb more water per unit time, enabling it to produce more water mist and thus increasing the water output of the humidifying device 1. Furthermore, the serrated portion 212 can also limit the water absorption component of the internal atomizing component 300, preventing it from detaching from the water absorption hole.

[0037] The serrated section 212 increases the contact area between water and the atomizing component 300. During atomization, water needs to be broken down into water mist by the atomizing component 300. The serrated section 212 structure allows water to have more opportunities to contact the atomizing component 300 as it passes through the water absorption hole 210, enabling more water molecules to be effectively atomized by the atomizing component 300 and improving the humidification effect.

[0038] Therefore, the humidification device 1 according to the present invention has the advantages of high water output and good humidification effect.

[0039] In some specific embodiments of this utility model, such as Figures 4-6 As shown, the atomizing component 300 includes a water-absorbing component 310 and an atomizing generator 320. The water-absorbing component 310 passes through the water-absorbing through-hole 210 and is adapted to absorb water from the humidifying water box 200. The atomizing generator 320 is installed on the side of the water-absorbing through-hole 310 facing the mist outlet 101 to generate water mist.

[0040] The user pours water into the humidifying water box 200, and the water in the humidifying water box 200 is absorbed by the water absorption component 310 through the water absorption hole 210. The water absorption component 310 is inserted into the water absorption hole 210, effectively absorbing water from the humidifying water box 200 into the water absorption hole 210. The atomizer 320 is installed on the side of the water absorption hole 210 facing the mist outlet 101. When the atomizer 320 is working, it uses micropore vibration technology to decompose water molecules in the water absorption component 310 into fine water mist particles. Micropore vibration technology typically uses high-frequency vibration to cause water molecules to vibrate violently in the micropores, thereby atomizing the water molecules into fine water mist particles. The generated water mist is released into the air through the mist outlet 101, increasing the humidity of the air.

[0041] Due to the synergistic effect of the water-absorbing component 310 and the atomizing generator 320, this humidifying device 1 can more efficiently convert water into water mist and release it into the air. The combination of the efficient water absorption capacity of the water-absorbing component 310 and the uniform atomization capacity of the atomizing generator 320 enables the humidifying device 1 to increase the air humidity in a shorter time, achieving a better humidification effect.

[0042] In some specific embodiments of this utility model, such as Figure 5 and Figure 8 As shown, the water-absorbing component 310 includes a water-absorbing column 311 and a water-absorbing block 312. The water-absorbing column 311 passes through the water-absorbing through hole 210. The water-absorbing block 312 is connected to one end of the water-absorbing column 311 and is located on the side of the water-absorbing through hole 210 away from the mist outlet 101.

[0043] One end of the water-absorbing column 311 passes through the water-absorbing hole 210 and is connected to the atomizer 320. The opposite end of the water-absorbing column 311 is connected to the water-absorbing block 312. Multiple limiting plates are constructed around the bottom of the water-absorbing block 312 to ensure that the water-absorbing block 312 is in the appropriate position.

[0044] The water-absorbing block 312 is located on the side of the water-absorbing through-hole 210 facing away from the mist outlet 202, and is in direct contact with the water in the humidifying water box 200. The water-absorbing block 312 absorbs the water in the humidifying water box 200 through capillary action and stores it inside itself. The water-absorbing column 311 passes through the water-absorbing through-hole 210, with one end connected to the water-absorbing block 312 and the other end facing the atomizer 320. The water-absorbing block 312 transfers the water absorbed by the water-absorbing column 311 to the vicinity of the atomizer 320 through capillary action.

[0045] The water-absorbing component 310, through the water-absorbing block 312 and the water-absorbing column 311, can provide a stable water supply to the atomizer 320. A stable water supply helps the atomizer 320 to atomize water molecules more evenly, producing finer and more uniform water mist particles.

[0046] In some specific embodiments of this utility model, such as Figure 5-7 As shown, there are multiple water-absorbing columns 311 and multiple water-absorbing holes 210. Multiple water-absorbing holes 312 are arranged at intervals along the length of the humidifying water box 200. The water-absorbing columns 311 and the water-absorbing holes 210 are arranged in a one-to-one correspondence. The side of the multiple water-absorbing columns 311 facing away from the mist outlet 101 is connected to the water-absorbing block 312.

[0047] Multiple water-absorbing holes 210 are arranged at intervals along the length of the humidifying water box 200. Each water-absorbing hole 210 is equipped with a water-absorbing column 311, which significantly increases the contact area between the water-absorbing component 310 and the water, allowing the water-absorbing block 312 to absorb water from the humidifying water box 1 more efficiently. The even distribution of multiple water-absorbing columns 311 ensures that water is evenly absorbed from different positions in the humidifying water box 200, avoiding water concentration in a certain area, thereby improving the utilization rate of water in the entire humidifying water box 200 and reducing water waste.

[0048] Meanwhile, multiple water-absorbing columns 311 and water-absorbing through holes 210 provide multiple channels for water flow, allowing water to flow more smoothly from the water storage chamber 230 to the spray chamber 240, reducing resistance during water flow and improving water flow transmission efficiency. In some specific embodiments of this utility model, such as Figure 4 As shown, a sealing ring 301 is constructed on the side of the atomizer 320 facing the water inlet 210. The sealing ring 301 surrounds the water inlet 210 and seals with the water inlet 210.

[0049] The sealing ring 301 surrounds and seals the water intake hole 210, effectively preventing water leakage from the gap between the atomizer 320 and the water intake hole 210. This sealing structure ensures that water is drawn into the atomizer 320 only through the water intake component 310 and does not leak out from other places, thus avoiding leakage problems. Furthermore, the integrated structure of the atomizing plate and the sealing ring 301 allows for a tighter fit during installation, reducing installation errors and ensuring that the sealing ring 301 can be accurately installed between the atomizer 320 and the water intake hole 210, further improving sealing performance.

[0050] In some specific embodiments of this utility model, such as Figure 7 and Figure 8 As shown, the humidifying water box 200 has a limiting ridge 220 on the side of the water intake hole 210 facing the mist outlet 101, and the limiting ridge 220 surrounds the outer periphery of the atomizer 320.

[0051] The limiting ridge 220 surrounds the outer periphery of the atomizer 320, ensuring that the atomizer 320 is precisely positioned in the correct position of the water intake hole 210 during installation. This prevents the atomizer 320 from shifting or tilting during installation, thus guaranteeing its alignment and sealing performance with the water intake hole 210. The limiting ridge 220 also provides additional support, preventing the atomizer 220 from loosening or shifting due to vibration or other external forces during use. This fixing effect ensures the stability of the atomizer 220 during long-term use, thereby improving the reliability and service life of the humidification device 1.

[0052] In some specific embodiments of this utility model, such as Figures 3-6 As shown, the humidifying water box 200 is internally divided into a water storage chamber 230 and a spray chamber 240. The spray chamber 240 is located on the side of the water storage chamber 220 facing the mist outlet 101, and the water intake hole 210 is located on the side of the spray chamber 240 away from the mist outlet 101. The spray chamber 240 can be located in the middle of the humidifying water box 200, corresponding to the position of the spray outlet 101.

[0053] The separation of the water storage chamber 230 and the spray chamber 240 allows the water to flow more orderly from the water storage chamber 230 to the spray chamber 240. The water is first stored in the water storage chamber 230, then enters the spray chamber 240 through the water suction hole 210, and finally reaches the atomizing component 300. This avoids disorderly water flow in the humidifying water box 200 and reduces water waste.

[0054] In some specific embodiments of this utility model, such as Figure 3 and Figure 6 As shown, the humidifying water box 200 includes a base box 201, a lid 202, and a top cover 203. The interior of the base box 201 is divided into a water storage chamber 230 and a spray chamber 240, and a water intake hole 210 is formed inside the base box 201. The lid 202 covers the top surface of the water storage chamber 230 to seal it. The top cover 203 covers the lid 202 and seals the top surface of the base box 201 to seal the spray chamber 240. The lid 202 and the top cover 203 together form a water inlet 204. A mist outlet 101 is also constructed on the side of the base box 201 adjacent to the spray chamber 240, and the lid 202 has a notch of the same shape as the spray chamber 240.

[0055] The water inlet 204 is formed by the cover 202 and the top cover 203, a design that makes the water filling process more convenient. Users can directly pour water into the water storage chamber 230 through the water inlet 204 without having to open the entire humidifying water box 200. This design not only improves the convenience of water filling but also reduces the risk of water splashing or overflowing during the filling process.

[0056] The lid 202 covers the top surface of the water storage cavity 230, and the top cover 203 covers the lid 202 and seals the top surface of the bottom box 201. This double-sealed structure can effectively prevent water from leaking out of the water box, and the combination of the lid 202 and the top cover 203 provides a physical seal.

[0057] In some specific embodiments of this utility model, such as Figures 3-7 As shown, the bottom box 201 is constructed with a drain outlet 250, which is located on the side surface of the bottom box 201 opposite to the mist outlet 101 and at the connection between the bottom and the side of the bottom box 201.

[0058] Unlike existing humidifiers where the water inlet and outlet are shared, the internal structure of the humidifier water box may restrict the drainage, preventing some residual water from flowing out smoothly. For example, the bottom of the humidifier water box may have recesses or corners, causing water to easily stagnate in these areas during drainage. In this embodiment, the drain outlet 250 is separately located, for example, at the connection between the bottom and side of the base box 201. This allows drainage directly from the bottom of the humidifier water box 200, enabling water to flow from the lowest point of the humidifier water box 200, effectively solving the problem of residual water not being completely drained at once.

[0059] Because the drain outlet 250 is located on the side surface of the bottom box 201 facing away from the mist outlet 101 and at the junction of the bottom and side, its position design allows water to flow more directly from inside the humidifying water box 200 to the drain outlet 250 during drainage. In actual use, especially when frequent water changes are required or the humidifier 1 is not used for a long time, it can quickly empty the water in the humidifying water box 200, reducing the time water stays in the humidifying water box 200 and preventing water deterioration or bacterial growth.

[0060] The following describes a refrigerator (not shown in the figure) according to an embodiment of the present invention.

[0061] The refrigerator according to an embodiment of the present invention includes a cabinet, a refrigerator door 10, and a humidification device 1 as described in the present invention.

[0062] The refrigerator body has an internal cavity. The refrigerator door 10 is closable on one side of the refrigerator body and covers the cavity. A humidifier 1 is installed on the side of the refrigerator door 10 facing the cavity. A storage shelf 11 is provided on the side of the refrigerator door 10 facing the cavity, and the humidifier 1 is connected to the bottom of the storage shelf 11.

[0063] like Figure 11As shown, the humidifier 1 is detachably installed on the refrigerator door 10 by means of a snap-fit. The humidifier 1 is located on the inner wall of the refrigerator door, and its side panel away from the mist outlet 101 is fixed to the inner wall of the refrigerator door. The mist outlet of the humidifier 1 is set towards the storage area inside the refrigerator to diffuse the atomized water vapor into the refrigerator. The refrigerator defines a refrigerated space for storing food. When the refrigerator door is closed, the humidifier 1 closes the refrigerated space along with the refrigerator door 10 to achieve uniform regulation of the air humidity inside the refrigerator. In addition, the humidifier 1 is located at the bottom of the storage shelf 11 and forms an integral structure with the storage shelf 11, which has a strong sense of integration and improves the concealment of the inside of the refrigerator without affecting the use function of the storage shelf 11.

[0064] The refrigerator of this utility model embodiment has the advantages of high water output and good humidification effect by using the humidification device 1 of the above embodiment.
