Description

Technical Field

[0001] The invention relates to the technical field of dehumidification devices, and in particular discloses a rotary dehumidifier. Background Art

[0002] With the rapid development of modern industry and the increasing demand for living environment comfort, precise control of air humidity has become increasingly critical in many fields. As a highly efficient dehumidification equipment, rotary dehumidifiers are widely used in industrial production, warehousing and logistics, medicine and health, electronic and electrical manufacturing, commercial and civil buildings, and other fields. For example, in electronic chip manufacturing workshops, excessive humidity may cause chip short circuits, corrosion, and other problems, seriously affecting product quality and production efficiency; in the field of food storage, a suitable humidity environment can effectively extend the shelf life of food and reduce losses such as mildew; in high-end residential and commercial places, good humidity control can help improve the comfort of the indoor environment and prevent mold growth and damage to decorative materials. Therefore, the market demand for rotary dehumidifiers continues to grow.

[0003] However, existing rotary dehumidifiers have problems in structural design, which seriously restricts their further optimization and wide application.

[0004] Among them, regarding the location of the circulating fan, in the structural design of the traditional rotary dehumidifier, the circulating fan is usually located on one or both sides of the dehumidification wheel, and is mostly arranged externally. In this layout, in order to ensure that the fan can effectively transport air to the dehumidification wheel and smoothly send out the treated air, a large space needs to be reserved to accommodate the fan and its connecting pipes. When the fan is located on the side of the wheel, its axial length will directly increase the overall size of the rotary dehumidifier in this direction, causing the equipment to occupy too much space in the horizontal direction, resulting in an increase in volume.

[0005] In summary, the existing rotary dehumidifiers are large in size and thickness due to the unreasonable location of the circulating fan, and an innovative structural design solution is urgently needed to solve these technical problems. Summary of the invention

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] See also Figures 1 to 9 The present embodiment provides a rotary dehumidifier, comprising a housing 1, a support assembly 2 and a circulation fan assembly 7 arranged in the housing 1, the support assembly 2 comprising a support plate 21 and a through hole 213 arranged on the support plate 21, a first surface 211 of the support plate 21 extending toward the center of the through hole 213 to provide a mounting portion 23, the mounting portion 23 comprising a bottom surface 231 and a side wall 232, the bottom surface 231 and the side wall 232 forming a first cavity for mounting the circulation fan assembly 7, the support plate 21 comprising a second surface 212 arranged opposite to the first surface 211, the through hole 213 passes through the first surface 211 and the second surface 212, the first cavity comprising a first opening (not marked in the figure), the first opening facing the first surface 211.

[0043] In this embodiment, the circulation fan assembly 7 is cleverly accommodated in the mounting portion 23 of the bracket assembly 2, thereby achieving an organic combination of the circulation fan assembly 7 and the bracket structure. The circulation fan assembly no longer requires an independent large-area installation space, but is tightly embedded in a specific position of the bracket assembly 2, which greatly improves the space utilization in the vertical direction and effectively controls the space occupied by the dehumidifier in the horizontal direction. Since the internal components are compactly arranged, the spacing and gaps between the components are minimized, and the compactness of the entire dehumidifier internal structure directly affects the design of the shell. There is no need to design an overly large shell to accommodate scattered or unreasonable internal components. The smaller volume of the shell 1 not only reduces the material cost, but also makes the dehumidifier more compact and lightweight in appearance, and easier to install and place in various spatial environments. Whether in a small corner or limited space in a home, office or industrial site, it can be easily deployed, which improves the applicability and flexibility of the dehumidifier.

[0044] Specifically, the circulating fan assembly 7 includes a circulating fan housing 71 and a circulating fan mounted in the circulating fan housing 71, the first cavity includes a second opening 233 and a third opening 2311, the second opening 233 is arranged at the lower end of the first cavity, the third opening 2311 is arranged on the bottom plate 231, a first air inlet is provided on the circulating fan housing 71, the first air inlet is communicated with the third opening 2311, so that the outside circulating air can enter the circulating fan from the third opening 2311, and a first air outlet 711 is provided at the lower end of the circulating fan housing 71, the first air outlet 71 is adjacent to the second opening 233, and the first air outlet 711 and the second opening 233 are both facing the bottom of the support plate 21, so that the circulating air of the circulating fan can go out from the second opening.

[0045] Specifically, a first air guide member 8 is connected to the bracket assembly 2, and the first air guide member 8 includes an air duct 81 and a base plate 82. The base plate 82 includes a card plate 821. The air duct 11 includes a second air inlet 811 and a second air outlet 812 that are connected to each other. The second air inlet 811 is arranged on the card plate 821. A card slot 27 is arranged on the first surface 211. The card slot 27 is arranged adjacent to the second opening 233 of the mounting portion 23. The card plate 821 is snapped into the card slot 27. A gap is left between the card plate 821 and the bottom surface 231, so that the first air outlet 711 and the second air inlet 811 are connected to each other, and then the circulating air of the circulating fan can go out from the first air outlet 711, enter the gap and then enter the air duct 81, and finally go out from the second air outlet 812.

[0046] In this embodiment, the card plate 821 of the first air guide member 8 is installed on the first surface 211 in a snap-fitting manner, which makes full use of the surface space of the bracket assembly 2, so that the air duct 81 of the first air guide member 8 and other components (such as the circulating fan assembly, etc.) are more compact and reasonable in spatial layout. Compared with some traditional complex installation methods, this design reduces the extra space occupied by the installation of the air duct, helps to reduce the overall volume of the rotary dehumidifier, and achieve the goal of miniaturization of the equipment. The compact spatial layout also allows the connecting pipes and lines inside the equipment to be arranged shorter and more regularly, reducing the loss of energy during transmission, improving the energy utilization efficiency of the equipment, and also facilitating the assembly, maintenance and repair of the equipment.

[0047] Specifically, the rotary dehumidifier includes a heating component 4, which is arranged above the first surface 211 and is detachably connected to the support plate 21. The heating component 4 includes a heating element 41 and a second air guide member 42 connected to the inside of the heating element 41. The lower end of the second air guide member 42 is provided with a third air inlet 421, and the third air inlet 421 is abutted against the second air outlet 812. The third air inlet 421 is connected to the second air outlet 812, so that the wind from the circulating fan can enter the heating component 4.

[0048] Specifically, the rotary dehumidifier includes a wheel assembly 3, an arc-shaped first mounting frame 22 is arranged on the first surface 211, and the line segment from the center of the arc-shaped first mounting frame 22 to the center of the through hole 213 is perpendicular to the first surface 211, and the radius of the arc-shaped first mounting frame 22 is larger than the radius of the through hole, and the wheel assembly 3 is rotatably arranged in the first mounting frame 22, and a mounting shaft 26 is arranged on the first surface 211, and the mounting shaft 26 is located at the center of the through hole 213, and the wheel assembly 3 includes a hygroscopic wheel, and a mounting plug-in 33 is sleeved on the center hole of the hygroscopic wheel, and the central channel of the mounting plug-in 33 is sleeved on the mounting shaft 26, so that the wheel assembly 3 can be rotatably arranged in the first mounting frame 22, and the heating element 41 includes a third air outlet 411, and the third air outlet 411 faces a part of one side of the hygroscopic wheel of the wheel assembly 3.

[0049] In this embodiment, the arc-shaped first mounting frame 22 cooperates with the mounting shaft 26 located at the center of the through hole 213, so that the hygroscopic rotor can rotate stably and evenly. This structural design ensures that when the air flows through the hygroscopic rotor, the contact time and contact area of ​​each part with the rotor are relatively consistent, thereby achieving a uniform and efficient dehumidification effect. In the regeneration stage, the uniform rotation also ensures that each area of ​​the hygroscopic rotor can fully receive the treatment of the regeneration wind, making the regeneration process of the hygroscopic material more thorough and efficient, and helping to maintain the long-term stable dehumidification performance of the hygroscopic rotor.

[0050] Specifically, the rotary dehumidifier also includes a condensation module 5, which is arranged above the second surface 211. The condensation module 5 includes an air inlet cavity. A fourth air inlet 24 is also provided on the support plate 21. The fourth air inlet 24 is located below the through hole 213. The fourth air inlet 24 corresponds to the position of the air inlet cavity. The fourth air inlet 24 is connected to the air inlet cavity. The fourth air inlet 24 is arranged adjacent to the mounting portion 23. The fourth air inlet 24 faces a part of the second side surface of the hygroscopic rotary wheel. The third air outlet 411 corresponds to the position of the fourth air inlet 24.

[0051] This embodiment increases the opening area of ​​the air inlet by arranging the fourth air inlet 24 (i.e., the air inlet of the condensation assembly) on the support plate 21. According to the principles of fluid mechanics, under the same internal and external pressure difference, the larger the opening area, the larger the volume of air entering per unit time. More humid hot air will fully contact the condensation tube group after entering the condensation assembly. There is usually a low-temperature refrigerant flowing inside the condensation tube group, so that the outer surface temperature of the condensation tube group is relatively low. According to the principle of heat exchange, when the hot and humid air contacts the low-temperature surface of the condensation tube group, the water vapor in the air will undergo a phase change due to the cold, from gas to liquid. As the amount of air entering increases, the chance of water vapor contacting the condensation tube group is also greatly increased, thereby improving the efficiency of condensation and dehumidification.

[0052] And through the fourth air inlet 24 arranged on the support plate 21, the moist hot air from the fourth air inlet 24 can directly enter the air inlet cavity of the condensation component 5 without any obstruction, thereby ensuring smooth air flow.

[0053] Specifically, the support plate 21 includes a second surface 212 disposed opposite to the first surface 211 , the second installation frame 25 is disposed on the second surface 212 , and the condensation module includes a condensation assembly, which is detachably connected to the second installation frame 25 .

[0054] Specifically, the second mounting frame 25 includes an upper card plate 251, a lower card plate 252 and two enclosures 253 which are perpendicular to the upper card plate 251 and the lower card plate 252 and are arranged between the upper card plate 251 and the lower card plate 252. The condensation assembly includes a first mounting portion 51, a second mounting portion 52, and a condensation tube group (not shown in the figure) whose two ends are respectively plugged into the first mounting portion 51 and the second mounting portion 52. The shape of the first mounting portion 51 is adapted to the shape of the upper card plate 251, so that the first mounting portion 51 and the upper card plate 251 can be connected by a fixing member, and the shape of the second mounting portion 52 is adapted to the shape of the lower card plate 252, so that the second mounting portion 52 and the lower card plate 252 can be connected by a fixing member. The first mounting portion 51, the second mounting portion 52 and the two enclosures 253 together form a second cavity 254, and the condensation tube group is arranged in the second cavity 254.

[0055] Specifically, the condensation module 5 also includes a condensation seat, which is arranged on the second surface 212 and below the second mounting frame 25.

The air outlet cavity corresponds to the position of the opening 2311, and the air outlet cavity is connected to the opening 2311, so that the wind from the condensation component passes through the opening 2311 and then enters the circulation fan.

[0056] Specifically, the condensation seat includes a base 541 and a base cover 542 covering the base 541. The base 541 is arranged on the second surface 212. When the base cover 542 is covered with the base 541, an inner cavity is formed in the condensation seat. A water guide channel 544 is also arranged under the condensation seat. The water guide channel 544 is connected to the air outlet cavity for draining the condensed water.

[0057] Specifically, at least two connecting bars 2131 are connected from the center of the through hole 213 to the edge of the through hole 231 . In this embodiment, there are two connecting bars 2131 , which are arranged at the upper part of the through hole 231 , so as to stabilize the mounting portion 23 .

[0058] Specifically, the first air guide member 8 also includes a side wall plate 83 connected to the first edge of the bottom plate 82, and a connecting rod 84 connected to the second edge of the bottom plate 82. A notch 2321 is provided on the side wall 232 near the fourth air inlet 24, and the end 841 of the connecting rod is fixed in the notch 2321. A baffle 832 is provided on the third edge 831 of the side wall plate 83. The bottom plate 82, the side wall plate 83 and the baffle 832 form a channel, so that the outer edge 31 of the wheel assembly 3 can rotate in the channel.

[0059] Specifically, a accommodating cavity 833 is also provided on the third edge 831, and the rotary dehumidifier also includes a control component, which includes a motor 61 and a gear 62 connected to the motor 61.

[0060] In the present invention, the integrated design between the first air guide 8 and the wheel assembly 3 and the control assembly allows multiple functional components to be tightly combined. Its structure is compatible with the rotation space of the wheel assembly 3, reducing the extra space occupied. The gear 62 of the control assembly is cleverly placed in the accommodating cavity 833 of the side wall plate 83, making full use of the internal space of the first air guide 8 and avoiding the increase in the size of the equipment due to the separate setting of the control component. This compact and integrated design method helps to miniaturize and lighten the entire rotary dehumidifier, improves the utilization rate of the internal space of the equipment, and enables the equipment to integrate more functional components in a limited space, thereby improving the overall performance.

[0061] Specifically, the rotary dehumidifier also includes a fan assembly 9, the fan assembly 9 includes a fan (not shown in the figure), and the fan assembly 9 also includes a third mounting frame 91, and the third mounting frame 91 is fixedly connected to the first mounting frame 22 via a second fixing member (not shown in the figure).
