Description

Technical Field

[0001] This utility model relates to the field of electronic dehumidifier technology, and in particular to an energy-saving and space-saving electronic dehumidifier. Background Technology

[0002] Currently, during the rainy season and summer, due to high humidity and temperature, many foods such as rice, noodles, milk powder, biscuits, nuts, coffee, tea, medicines, and the mouths of condiment bottles such as soy sauce and vinegar are prone to mold and insect infestation. Many molds are extremely harmful to the human body, such as *Aspergillus polyphylla* (causing allergies), *Penicillium* (highly toxic), *Aspergillus flavus* (strongly carcinogenic), and *Aspergillus fumigatus* (causing infections and allergies). As for valuable items such as camera lenses, precision electronic products, stamps, antiques, calligraphy and paintings, and documents, they are also prone to mold and insect infestation in high humidity environments, leading to dirt and damage. As long as the air humidity can be reduced to a certain level, the chances of mold and insect infestation can be significantly reduced. Therefore, storing these foods, medicines, and items in a dehumidifying cabinet is a healthy and safe method. In an airtight space, electronic dehumidification methods are used to effectively reduce the original moisture in a specific volume of space, achieving the required functions such as moisture prevention, mold prevention, oxidation prevention, rust prevention, deterioration prevention, and quality change prevention. Such cabinets are called electronic dehumidifying cabinets.

[0003] The existing technology, authorized by announcement number CN208278677U, is titled "A Moisture-proof and Dehumidifying Health Food Storage Box." It includes a main body, side partitions, horizontal partitions, a back partition, and a dehumidification and drying mechanism. The side and back partitions are located within the main body, and the horizontal partitions are positioned between the side partitions, forming an air handling chamber and a storage chamber. The dehumidification and drying mechanism is located within the air handling chamber, and a connecting slide and a push-pull shelf are located at the bottom of the storage chamber. This reduces the humidity in the storage environment, preventing health foods from becoming damp and spoiling, and extending the storage period. However, dry air is denser than humid air, causing it to accumulate at the bottom of the box. When the cabinet door is opened, the internal dry air and external humid air exchange rapidly, causing the humidity inside the box to rise quickly. This results in unstable humidity levels for the product, requiring the electronic dehumidifier to operate for longer to remove the moisture introduced by opening the door, leading to increased energy consumption. Furthermore, the side-opening design of this patent has disadvantages such as taking up more space when the door is open and requiring the removal of items from the outside of the box before retrieving items from the inside, which is inconvenient.

[0004] The existing technology, authorized by publication number CN211811244U, entitled "Electronic Dehumidifying Box," includes a box body, an inlet, a door panel, a bracket, a dehumidifier, and an adjustment plate. The box body has brackets on both the left and right sides, and at least one adjustment plate is provided on each bracket. The adjustment plate has several threaded holes. The electronic dehumidifying box also includes several adjustment columns provided on the adjustment plate. One end of each adjustment column is provided with a stud that matches the threaded hole. The adjustment column is threadedly connected to the adjustment plate through the stud. This design can reduce the air humidity in the storage environment, prevent electronic equipment from getting damp, and extend its service life. However, this patent has the same disadvantages as the aforementioned patent when used.

[0005] This utility model proposes an energy-saving and space-saving electronic dehumidifier, which solves the problems of large fluctuations in air humidity, poor energy-saving effect, space occupation, and inconvenience of taking it out and putting it in related technologies. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an energy-saving and space-saving electronic dehumidifier. When in use, the door is located at the top of the cabinet, rather than the usual side. This alters the air exchange path when the door opens upwards, concentrating air exchange primarily within a small area at the top of the cabinet. Humid air entering the cabinet must overcome gravity, and the outflow of dry air from inside is also somewhat restricted, as it needs to move upwards to escape. This contradicts the natural air convection trend (horizontal or downward). This change in air exchange path reduces the amount of dry air exchanged between the cabinet and the humid air outside, allowing as much dry air as possible to remain inside the cabinet, thus maintaining stable humidity. This reduces the operating time of the electronic dehumidifier chip and improves energy efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An energy-saving and space-saving electronic dehumidifier box includes a box body, which includes a cover and two hinged rotating rods. An electronic dehumidifier core is embedded in the upper part of the inner wall of the box body. Two first rotating shaft seats are symmetrically fixed at the center of the top of the left and right inner sides of the box body, at a distance d1 from the rear side. The axis of each first rotating shaft seat is h1 from the top edge of the box body. Two second rotating shaft seats are symmetrically fixed at a distance d2 from the rear edge of the cover. Both first rotating shaft seats... The system comprises an interference fit and a rotating hinge with a horizontally positioned pivot shaft at one end of the hinge rod. The other ends of the two hinge rods are also horizontally positioned pivot shafts. Both pivot shafts are rotatably hinged to a second pivot seat located at the lower end of the cover plate. The axis of the second pivot seat is h2 from the bottom edge of the skirt. Viewed from the left front side, the hinge rod is slightly bent clockwise, with a length of d, where d1 = d + d2, and a bending height of h1 + h2. Therefore, when the cover plate is closed, the lower edge of the skirt can fit snugly against the top edge of the box. When the front edge of the cover plate is pushed upwards, it stands upright above the box. At this time, the hinge rods remain largely stationary; the rotation of pivot shafts is the primary movement, similar to the effect of a conventional hinged door. The rear edge of the cover plate can also be pushed upwards to open it, thus enhancing the usability of this dehumidifier.

[0009] Furthermore, if the length of the top edge of the side of the box is d0, let d satisfy the condition that d is greater than or equal to d0-d1. In this way, the composite mechanism of the cover plate, pivot one, pivot two, and hinged rotating rod can achieve a 180-degree rotation angle, allowing it to hang on the front side of the box, as shown below. Figure 2 Furthermore, during the movement of the cover from the covered state to the suspended state, if the distance between the axis of the second pivot and the upper surface of the cover is h3, the maximum height space required is d+h3-h1, which is approximately half of d0. This reduces the height space requirement by half compared to conventional hinged door boxes, thereby saving usable space.

[0010] Furthermore, both the first and second pivot seats are damped, allowing the cover plate to stop at any position during movement.

[0011] Compared to existing electronic dehumidifiers, this electronic dehumidifier offers multiple opening methods through its structure, including a lid, hinged lever, and two pivot seats. The lid can be opened simply 90 degrees from the front, like a conventional hinged door, for easy access to items; it can also be opened from the back, providing more operational options in special scenarios, such as when there is more space at the back of the cabinet; it can even be flipped 180 degrees and suspended on the front side, for example, in narrow cabinet spaces where front operation is limited, allowing for rear-entry access; and when the cabinet needs to be fully open and front space permits, the lid can be flipped 180 degrees and suspended, providing significant operational convenience.

[0012] Furthermore, the box body is a pentahedral square barrel shape with a missing top surface, and the inner edge of the top of the box body is provided with a raised guide edge;

[0013] With the above technical solution, the guide edge can play a guiding role when the cover is closed, ensuring that the cover can be accurately placed on the box.

[0014] Furthermore, a push cover is rotatably connected to the front end of the middle of the upper surface of the cover plate, a sealing strip is embedded at the edge of the lower surface of the cover plate, and the cover plate is a cover with a skirt around the perimeter, and its shape and area are equal to the opening of the box body;

[0015] The above technical solution allows for easy sealing of the box opening via a sealing strip, and easy opening or closing of the cover via a push-to-open mechanism.

[0016] Furthermore, a mounting groove is provided in the middle of the lower surface of the housing, and a storage battery is installed inside the mounting groove. A protective cover is threadedly connected to the lower end of the inner wall of the mounting groove by fastening bolts.

[0017] The above technical solution allows the electronic dehumidifier core to be powered by a storage battery.

[0018] Furthermore, a microcomputer control panel is provided on the upper part of one side of the outer wall of the housing, and a charging interface is provided on the lower part of one side of the rear outer wall of the housing.

[0019] The above technical solution allows for easy control of the switch by connecting the microcomputer control panel to the electronic dehumidifier core, and facilitates charging of the battery through the charging interface.

[0020] This utility model has the following beneficial effects:

[0021] 1. This utility model proposes an energy-saving and space-saving electronic dehumidifier. Compared with existing electronic dehumidifiers, this model places the door at the top of the cabinet instead of the usual side. This changes the air exchange path when the door is opened. The door opens upwards, and the exchange with the outside air mainly takes place in a small area at the top of the cabinet. The outside humid air needs to overcome gravity to enter the cabinet, and the outflow of dry air from the cabinet is also somewhat restricted because it needs to move upwards to be discharged. This contradicts the natural air convection trend (horizontal or downward direction). This change in the air exchange path reduces the amount of dry air exchanged between the inside and outside humid air, allowing as much dry air as possible to be retained inside the cabinet, thus maintaining a stable humidity level. This reduces the working time of the electronic dehumidifier chip and results in better energy saving.

[0022] 2. This utility model proposes an energy-saving and space-saving electronic desiccant. Compared with existing electronic desiccant boxes, this electronic desiccant achieves multiple opening methods through its structure, including a lid, hinged rotating rod, and two pivot seats. The lid can be opened simply 90 degrees from the front like a conventional hinged door for easy access to items; it can also be opened from the back, providing more operational options in special scenarios, such as when there is more space at the back of the box; it can even be flipped 180 degrees and suspended on the front side, for example, in narrow cabinet spaces where front operation space is limited, allowing access to items from the back; and when the box needs to be fully open and front space allows, the lid can be flipped 180 degrees and suspended, providing great operational convenience and high practicality.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0032] Reference Figure 1-6 This utility model provides an embodiment of an energy-saving and space-saving electronic dehumidifier box, comprising a box body 1, a cover plate 2, and two hinged rotating rods 3. An electronic dehumidifier core 13 is embedded in the upper part of the inner wall of the box body 1. Two first rotating shaft seats 14 are symmetrically fixed at the center of the top of the left and right inner sides of the box body 1, at a distance d1 from the rear side. The axis of the first rotating shaft seat 14 is h1 from the top edge of the box body 1. Two second rotating shaft seats 22 are symmetrically fixed at a distance d2 from the rear edge of the cover plate 2. Both first rotating shaft seats 14 are interference-fitted and rotatably hinged to a rotating shaft 31 laterally arranged on one end of the hinged rotating rod 3. A second rotating shaft 32 is rotatably hinged to the other end of the two hinged rotating rods 3. The second pivot seat 22 is located at the lower end of the cover plate 2. The axis of the second pivot seat 22 is h2 from the bottom edge of the skirt. Observed from the left front side, the hinge rod 3 is slightly bent clockwise, with a length of d, where d1 = d + d2, and its bending height is h1 + h2. The first pivot seat 14 and the second pivot seat 22 are damped. Therefore, when the cover plate 2 is closed, the lower edge of the skirt of the cover plate 2 can be tightly pressed against the top edge of the box body 1. After the cover plate 2 is closed, when the front edge of the cover plate 2 is pushed upward, the cover plate 2 can stand upright above the box body 1. At this time, the hinge rod 3 basically does not move; the rotational movement of the second pivot 32 is the main movement, similar to the effect of a conventional hinged door. After the cover plate 2 is closed, the rear edge of the cover plate 2 can also be pushed upward to open the cover plate 2, thus giving this dehumidifier more usability.

[0033] Compared to existing electronic dehumidifiers, this electronic dehumidifier offers multiple opening methods through its structure, including the lid 2, hinged lever 3, and two pivot seats. The lid 2 can be opened simply 90 degrees from the front like a conventional hinged door for easy access to items, or it can be opened from the back, providing more operational options in special scenarios, such as when there is more space behind the cabinet 1. Furthermore, it can be flipped 180 degrees and suspended from the front. For example, in a narrow cabinet space where front access is limited, opening the lid 2 from the back allows for easy access to items. Conversely, when the cabinet 1 needs to be fully open and front space permits, the lid 2 can be flipped 180 degrees and suspended, providing significant operational convenience.

[0034] Both the first and second pivot seats 22 are damped, allowing the cover plate 2 to stop at any position during movement. The box 1 is a pentahedral cuboid with a missing top surface. A raised guide edge is provided on the inner edge of the top of the box 1. When closing the cover plate 2, the guide edge acts as a guide, ensuring that the cover plate 2 accurately covers the box 1. A push cover 21 is rotatably connected to the front end of the middle of the upper surface of the cover plate 2. A sealing strip 23 is embedded at the edge of the lower surface of the cover plate 2. The cover plate 2 is a cover with a skirt around its perimeter, and its shape and area are equal to the opening of the box 1. The sealing strip 23 facilitates sealing of the opening. The push-to-open cover 21 facilitates the opening and closing of the cover plate 2. A mounting groove 4 is provided in the middle of the lower surface of the housing 1, and a battery 41 is installed inside the mounting groove 4. A protective cover 42 is threadedly connected to the lower end of the inner wall of the mounting groove 4 via fastening bolts. The battery 41 provides power to the electronic dehumidifier core 13. A microcomputer control panel 11 is located on the upper part of one side of the outer wall of the housing 1, and a charging interface 12 is located on the lower part of one side of the rear outer wall of the housing 1. The microcomputer control panel 11 is electrically connected to the electronic dehumidifier core 13 for easy control of its switching, and the charging interface 12 facilitates charging of the battery 41.

[0035] Working principle: When in use, the door can be opened by pushing the front edge of the cover 2 from the front or the rear edge from the back. Pushing the front edge also allows the cover 2 to rotate 180 degrees and suspend at the front side. During this process, the first and second pivot seats and the hinge rod 3 move in tandem, and damping ensures that the cover 2 stops at any position. When closing, the cover 2 closes under the guidance of gravity and the guide edge, and is sealed by the sealing ring 14. The electronic dehumidifier core 13 inside the cabinet operates according to humidity changes, reducing the entry of humid air from the outside and thus lowering the operating frequency. The battery 41 provides power to the electronic dehumidifier core 13, and the charging interface 12 facilitates charging.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
