Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a dehumidifier. Background Art

[0002] The traditional dehumidifier's PTC (positive temperature coefficient) heating plate design has some inherent limitations. First, the PTC heating plate is usually fixed on a heat-conducting aluminum plate, and the heat is transferred to both sides through the central aluminum plate (such as Figure 1 (As shown). While this design can achieve heat transfer to a certain extent, the size and shape of the heater plate limit its heating area, making it difficult to efficiently and evenly cover the entire dehumidification area. This results in uneven heat distribution during heat transfer, with some areas overheating while others remain cooler, affecting the efficient regeneration of the desiccant and the overall dehumidification effect.

[0003] Secondly, due to the limited heating area and uneven heat transfer, traditional dehumidifiers often have a long drying time, typically 15 to 24 hours. This not only increases user waiting time and reduces the dehumidifier's usability, but also may damage the device's internal materials due to prolonged high-temperature heating, shortening the dehumidifier's service life. Furthermore, prolonged drying times directly impact the user experience. Utility Model Content

As used in this specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include the plural forms.

[0029] It should be further understood that the term " / and / " used in this specification of the present invention and the appended claims refers to any combination and all possible combinations of one or more of the related listed items, and includes these combinations.

[0030] Please refer to Figure 2 and Figure 3 , this embodiment provides a dehumidifier, including: a housing 1, a desiccant 2 and two heating elements 3. An accommodation cavity 4 and a ventilation opening 5 communicating with the accommodation cavity 4 are provided on the housing 1. The two heating elements 3 are arranged in the accommodation cavity 4, and the desiccant 2 is arranged between the two heating elements 3.

[0031] In this embodiment, by arranging the desiccant 2 between the two heating elements 3, not only can the heat of the heating element 3 be evenly transferred to the desiccant 2, but also the heating area is increased, thereby enabling the desiccant 2 to be quickly dried, shortening the drying time, and thus improving the user experience and the competitiveness of the product.

[0032] Among them, Figure 3 The arrows inside indicate the direction of heat transfer.

[0033] In this embodiment, the ventilation openings 5 on the housing 1 can all allow air to pass through. When the air carrying water vapor enters the accommodation cavity 4 through the ventilation openings 5, the water vapor in the air will be absorbed by the desiccant 2, thereby achieving dehumidification of the surrounding environment. When the moisture inside the desiccant 2 is saturated, the heating element 3 will start to work. At this time, the heating element 3 will perform a rapid dehydration treatment on the desiccant 2 in the accommodation cavity 4. In this way, the desiccant 2 in the accommodation cavity 4 can quickly restore its water absorption function and continue to efficiently absorb the moisture in the air. This design enables the desiccant 2 to be recycled, and users do not need to frequently replace the desiccant 2. This not only improves the practicality and convenience of the dehumidifier but also reduces the use cost to a certain extent.

[0034] In this embodiment, the heating element 3 is an ohmic heating sheet.

[0035] Ohmic heating sheets are usually designed to be thin sheets and can be evenly distributed on the surface or inside of the object to be heated. This design makes the heating more uniform and avoids problems such as local overheating or insufficient heating that may occur in traditional heating methods. In addition, ohmic heating sheets generate heat directly through current, with high energy conversion efficiency. Compared with traditional heating methods such as resistance wire heating or gas heating, ohmic heating sheets can reach the set temperature more quickly and consume less energy.

[0036] Among them, the ohmic heating sheet mainly consists of an ohmic sheet, heating wires, and a circuit.

[0037] The ohmic sheet is the core component of the ohmic heating sheet and is usually made of materials with high resistivity and good thermal conductivity, such as ceramics, graphite, or other composite materials. The design of the ohmic sheet enables it to generate heat when powered on, which is achieved by the resistance encountered when the current passes through the material. The greater the resistance, the more heat is generated.

[0038] The heating wire is a thin metal wire embedded in or attached to the ohmic sheet, usually made of nickel-chromium alloy, iron-chromium-aluminum alloy or other metal materials with high temperature resistance and high resistance. The main function of the heating wire is to convert electrical energy into heat energy. When an electric current passes through the heating wire, due to the existence of resistance, the heating wire will quickly heat up and transfer the heat to the ohmic sheet. The design and layout of the heating wire are crucial for the heating efficiency and uniformity of the ohmic heating sheet. A reasonable heating wire layout can ensure uniform heat distribution on the ohmic sheet, thereby improving the heating effect.

[0039] The circuit is the control part of the ohmic heating sheet, responsible for supplying electrical energy to the heating wire and controlling the heating power and temperature of the heating sheet. The circuit usually includes components such as a power input terminal, a temperature controller, and a fuse to ensure that the ohmic heating sheet operates under safe and stable conditions. The temperature controller can automatically adjust the heating power according to the set temperature range to keep the heating sheet operating within the required temperature range. The fuse is used to prevent safety hazards such as equipment damage or fire caused by excessive current.

[0040] In this embodiment, please refer to Figure 4 , the housing 1 includes: a first housing 6 and a second housing 7, the first housing 6 and the second housing 7 are connected, and the two heating elements 3 are respectively arranged on the first housing 6 and the second housing 7.

[0041] By dividing the housing 1 into the first housing 6 and the second housing 7, this design realizes modularization. This modular design makes the manufacturing, assembly, and maintenance of the housing 1 simpler and more efficient. Each part can be produced independently and then combined together in the final assembly stage, which helps to improve production efficiency and reduce production costs. At the same time, if one of the heating elements 3 fails or needs maintenance, the relevant housing 1 module can be disassembled and replaced separately without affecting the operation of the entire system. This greatly reduces the maintenance cost and time, and improves the availability and reliability of the equipment. The first housing 6 and the second housing 7 can be independently formed structures or integrally formed into the housing 1.

[0042] In this embodiment, the first housing 6 and the second housing 7 are connected into a flat structure.

[0043] Since the first housing 6 and the second housing 7 are closely connected to form a flat structure, this design significantly reduces the overall volume of the dehumidifier. Therefore, this dehumidifier is very suitable for dehumidification tasks in small spaces. Whether in a narrow room, closet or other limited spaces, it can efficiently play the role of dehumidification to ensure that the environment remains dry and comfortable.

[0044] In a specific embodiment, the first housing 6 and the second housing 7 are in the shape of a tennis racket.

[0045] The bottom surface of the second housing 7 is designed as a curved surface structure. This design not only increases the structural complexity and aesthetics but also endows it with unique functionality. It is worth noting that the curvature of this curved surface is set relatively small. Such a design choice enables the second housing 7 to maintain the necessary arc while avoiding potential structural instability or inconvenience in use caused by excessive bending. In addition, to achieve a perfect match and collaborative work with the second housing 7, the edge shape of the first housing 6 is the same as that of the second housing 7. This highly consistent design ensures excellent sealing performance and structural stability when the two are combined, thus enhancing the overall performance and reliability.

[0046] In some embodiments, the first housing 6 and the second housing 7 can be connected by snap - fitting. Specifically, by providing convex - concave structures on the first housing 6 and the second housing 7, the first housing 6 and the second housing 7 can be tightly snapped together. This connection method is simple to operate and has a low cost. However, the snap - fit strength may not be as high as that of other connection methods, and loosening or wear may occur after long - term use.

[0047] In some embodiments, the first housing 6 and the second housing 7 can be connected by screw connection. Specifically, by reserving screw holes on both the first housing 6 and the second housing 7, the two first housing 6 and the second housing 7 are fixed together using screws and nuts (nuts may not be used). This connection method has high connection strength, and the connection is stable and durable.

[0048] In this embodiment, ultrasonic welding is used to connect the first housing 6 and the second housing 7. Ultrasonic welding uses high - frequency vibration waves to heat the surfaces of the first housing 6 and the second housing 7 to a molten state, thereby forming a firm welded joint. This method does not require additional adhesives or mechanical fasteners, has a fast connection speed and high strength. In addition, ultrasonic welding can achieve a sealed connection without damaging the appearance, improving the waterproof performance and durability of the product.

[0049] In this embodiment, a plurality of ventilation openings 5 are provided on both the first housing 6 and the second housing 7.

[0050] The design of the plurality of ventilation openings 5 can significantly increase the contact area and contact frequency between the air and the desiccant 2, thereby improving the dehumidification efficiency. The air flows into the interior of the housing 1 through the ventilation openings 5 and comes into full contact with the desiccant 2. The moisture in the air is effectively absorbed, achieving the purpose of dehumidification. At the same time, the design of the plurality of ventilation openings 5 enables the air to come into more sufficient contact with the desiccant 2, thereby improving the utilization rate of the desiccant 2. This helps to extend the service life of the desiccant 2, reduce the replacement frequency, and lower the maintenance cost.

[0051] It should be noted that the ventilation opening 5 may not be provided on the first housing 6 or the second housing 7, and the ventilation opening 5 is only provided on the housing 1 on one side. The specific structural arrangement depends on the actual situation.

[0052] In this embodiment, the heating element 3 is sheet-shaped and attached to the inner wall of the housing 1.

[0053] Specifically, both heating elements 3 are sheet-shaped, and one of the heating elements 3 is attached to the inner wall of the first housing 6, and the other heating element 3 is attached to the inner wall of the second housing 7.

[0054] The sheet-shaped heating element 3 can distribute heat more evenly. This design enables the heat to be transferred to the desiccant 2 quickly and evenly, improving the heating efficiency. Due to the high heat transfer efficiency, this structure can reach the required heating temperature in a shorter time, thus reducing energy consumption. In addition, since the heat is evenly distributed, the situation of local overheating or insufficient temperature is avoided, further improving the energy utilization efficiency.

[0055] In this embodiment, the desiccant 2 includes a plurality of desiccant particles, and the dimensions of the desiccant particles in all directions are larger than the dimension of the ventilation opening 5.

[0056] Since the size of the desiccant particles is larger than the size of the ventilation opening 5, this design can effectively prevent the desiccant 2 from leaking through the ventilation opening 5 during use.

[0057] In some embodiments, the desiccant 2 is a silica gel desiccant. The silica gel desiccant is a colorless transparent, silicon dioxide crystal (also known as silica gel), which is a crystal that does not undergo chemical reactions. The interior of this crystal is a very fine pore network structure. These capillary pores can absorb moisture and retain the moisture through their physical attraction. The silica gel desiccant has strong moisture absorption ability and adsorption performance. Even if the silica gel desiccant is completely immersed in water, it will not soften or liquefy. It has the characteristics of non-toxic, odorless, non-corrosive, and pollution-free, so it can be in direct contact with any item.

[0058] In addition to ordinary desiccants, there are also color-changing silica gel desiccants available for selection. The color-changing silica gel desiccant contains indicators such as cobalt chloride. When the moisture absorption reaches the saturation state, the color will change from blue to pink, thus intuitively prompting the user that drying and regeneration treatment is required.

[0059] In some embodiments, the desiccant 2 can also be replaced with a water-absorbing sponge. Compared with traditional desiccants, the water-absorbing sponge has a faster water absorption speed and a stronger water absorption capacity, and can achieve an ideal drying effect in a shorter time. After reaching the saturation state, the water-absorbing sponge can restore its water absorption capacity by drying or baking, so as to achieve repeated use. This reusable characteristic reduces the use cost, reduces waste, and contributes to environmental protection. In addition, the water-absorbing sponge can adapt to the housing 1 of different shapes and sizes, and only needs to cut or adjust the size of the sponge according to actual needs.

[0060] In this embodiment, the vent 5 can be a long-strip vent, a round-hole vent, a square vent, or a special-shaped vent. The specific shape of the vent 5 can be set according to actual use, and this embodiment does not limit this.

[0061] In this embodiment, it further includes: an indicator window 8 (as Figure 4 shown), and the indicator window 8 is arranged on the housing 1.

[0062] The arrangement of the indicator window 8 allows the user to directly observe the state of the desiccant 2 inside the housing 1 without opening the housing 1.

[0063] In a specific embodiment, when orange is seen inside the indicator window 8, the desiccant 2 is in a dry state at this time, and when dark green is seen inside the indicator window 8, the desiccant 2 is in a saturated state at this time. At this time, the desiccant 2 needs to be heated by the heating element 3 to remove the moisture inside the desiccant 2, so that the desiccant 2 can restore its water absorption function again, so as to dehumidify more effectively.

[0064] Further, please refer to Figures 5 - 7 , a buckle 9 is arranged on the indicator window 8, and a clamping groove 10 is arranged on the housing 1; alternatively, a clamping groove 10 is arranged on the indicator window 8, and a buckle 9 is arranged on the housing 1, and the indicator window 8 and the housing 1 are clamped by embedding the buckle 9 into the clamping groove 10.

[0065] The design of the buckle 9 and the clamping groove 10 makes the connection between the indicator window 8 and the housing 1 very simple and fast. Just align the buckle 9 with the clamping groove 10 to complete the installation, without additional tools or complex operation steps. The tight fit of the buckle 9 and the clamping groove 10 ensures a firm connection between the indicator window 8 and the housing 1. This structure can effectively prevent the indicator window 8 from loosening or falling off during use, and ensures the overall stability and safety of the device.

[0066] Wherein, the clamping groove 10 is formed by a plurality of protrusions 11 arranged at intervals.

[0067] When the indicator window 8 needs to be installed on the shell 1, just press the buckle 9 according to the position of the slot 10, and then rotate the indicator window 8 so that a limit is formed between the protrusion 11 and the buckle 9, thereby achieving the snap connection between the indicator window 8 and the shell 1.

[0068] The slot 10, formed by multiple spaced protrusions 11, forms a multi-point lock when engaged with the clip 9, significantly enhancing the stability of the connection between the indicator window 8 and the housing 1. This multi-point support design prevents the indicator window 8 from falling off or loosening when subjected to external forces, ensuring the overall stability of the device. The protrusions 11 in the slot 10 make it easier for the clip 9 to engage and lock into the protrusions 11, simplifying the installation process. Users can complete installation without the need for additional tools or complex steps, improving installation efficiency.

[0069] In this embodiment, the power supply further includes a power plug 12 (such as Figure 4 As shown), the power plug 12 is electrically connected to the two heating elements 3.

[0070] The power plug 12 is directly mounted on the housing 1 and electrically connected to the heating element 3. This integrated design simplifies the overall structure of the device, reduces the use of wires and connectors, and thus reduces production costs and failure rates. Furthermore, users no longer need to find or carry a separate power adapter; they can simply plug the device's built-in power plug 12 into an outlet for power, greatly improving ease of use.

[0071] In this embodiment, the device further includes: an indicator light 13 (such as Figure 4 As shown), the indicator light 13 is electrically connected to the power plug 12,

[0072] Indicator light 13 visually displays the device's operating status. When the power plug 12 is plugged into a socket and powered on, indicator light 13 illuminates, indicating that the device is powered on and operational. This provides the user with clear visual feedback, making it easier to understand the device's operating status. If the device experiences a malfunction or abnormality, such as poor contact with the power plug 12 or damage to the heating element 3, indicator light 13 may flash or go out, prompting the user to promptly inspect and address the issue. This fault warning feature helps avoid potential safety hazards and property damage.

[0073] In this embodiment, a hanging member 14 (such as Figure 2 shown).

[0074] The design of the hanging member 14 enables the housing 1 to be easily hung on a wall, a bracket or other fixed structure, thereby reducing the space occupied by the dehumidifier.

[0075] In some embodiments, the hanging member 14 is a hanging rope.

[0076] The lanyard is fixed on the housing 1 and a part of it is exposed. After the first housing 6 is closed on the second housing 7, only a part of the lanyard can be seen on the outside.

[0077] In this embodiment, by adopting a more efficient and uniform ohmic heating technology, a significant increase in the heating area is achieved, with an increase of up to 300%. This innovative design ensures that the desiccant 2 can fully and sufficiently contact the heat, thereby greatly accelerating the drying process and reducing the drying time by 200%. This improvement not only greatly improves the drying efficiency but also significantly optimizes the user's product usage experience.

[0078] The various embodiments in the specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other.
