Figure 2 As shown, a water storage tank 15 is provided on the middle partition 12, an evaporator 14 is provided in the water storage tank 15, a compressor 13 is provided under the middle partition 12, and a heat dissipation component is provided on one side of the middle partition 12. The water dispenser is also provided with a drying filter 24, and cold water can be prepared by the above components. The present application adopts a stepped middle partition 12, so that the upper and lower sides and the horizontal side of the main board 121 form installation spaces respectively, which can realize the compact arrangement of the evaporator 14, the compressor 13 and the heat dissipation component, which is conducive to improving space utilization, reducing the body volume, and promoting the miniaturization of the whole machine. Among them, the fan 16 is arranged on the first step portion 123, and the fan 16, the evaporator 14, and the compressor 13 are staggered in vertical height, which is conducive to arranging the fan 16 at a height position close to the middle of the body, so as to optimize the overall heat dissipation effect of the body, and at the same time, more space is left at the upper end of the body to arrange structures such as the inlet and outlet water control valve 20, and the fan 16 can be pulled out and disassembled along the first step portion 123, and the disassembly and assembly are more flexible and are not limited by the size of the space above the fan 16; and the connecting plate 122 is provided with an air suction port 124 facing the fan 16, so that the fan 16 can absorb hot air through the air suction port 124 to blow the hot air out of the outer shell, so that the heat dissipation is smoother and more timely, which can improve the heat dissipation efficiency and heat dissipation effect.

[0048] like Figure 1As shown, the housing includes a front cover 10 and a rear cover 11 which are arranged opposite to each other, the front cover 10 and the rear cover 11 are placed vertically, the middle partition 12 is vertically connected between the front cover 10 and the rear cover 11, and the housing also includes a main housing 18, the top and bottom of the main housing 18 are closed, and a front opening and a rear opening are opened, and the front cover 10 and the rear cover 11 are used to close the front opening and the rear opening respectively. When installing, the middle partition 12 can be fixed between the front cover 10 and the rear cover 11 first, and then the water storage tank 15, the heat dissipation assembly and other components are installed, and then these components are pushed into the installation cavity 201 of the main housing 18 together. When the main housing 18 has a bottom wall, the compressor 13 is directly fixed on the bottom wall, and the installation order of the compressor 13 and the above-mentioned middle partition 12 and other multiple components is not limited, and the compressor 13 can be installed first or later. Alternatively, when the main housing 18 is not provided with a bottom wall, the housing also includes a bottom plate 19, and the bottom plate 19 can close the bottom opening of the main housing 18. During installation, the compressor 13 is fixed on the bottom plate 19, the middle partition plate 12 and the bottom plate 19 are fixed between the front cover 10 and the rear cover 11, and then the water storage bladder 15, the heat dissipation assembly and other components are installed, and then these components are pushed together into the installation cavity 201 of the main shell 18. The middle partition plate 12 is provided with a mounting hole 204, and the bottom of the water storage bladder 15 is provided with a mounting stud, which can realize the fixing of the water storage bladder 15 on the middle partition plate 12.

[0049] like Figure 1 As shown, the upper end of the rear cover 11 is provided with a control valve 20 and other structures for controlling the inflow and outflow of water, resulting in very limited space above the first step portion 123. To facilitate the installation of the fan 16, the fan 16 can be disassembled and assembled in a pull-out manner, which can improve its disassembly and assembly flexibility. When the fan 16 needs to be maintained or cleaned later, the fan 16 can be pulled out horizontally from the upper edge of the first step portion 123, and then the fan 16 can be reinstalled horizontally to the first step portion 123, which is easy to operate and efficient.

[0050] Furthermore, there is a certain space between the upper end of the fan 16 and the water storage tank 15, which is convenient for the fan 16 to absorb air, and the lower end of the fan 16 is directly opposite the air suction port 124, which can prevent the connecting plate 122 from affecting the air suction of the fan 16, so that the overall air suction effect of the fan 16 is good.

[0051] As a preferred embodiment of the present application, a notch 125 is provided at the end where the main board 121 and the connecting board 122 are connected, and the notch 125 is communicated with the air intake port 124 .

[0052] By providing the notch 125, an escape space can be provided for the blades of the fan 16 to prevent the blades from hitting the mainboard 121, and the notch 125 is connected with the air suction port 124 to increase the range of the air suction port 124, which is beneficial for more hot air (per unit time) to be guided to the fan 16 through the notch 125 and the air suction port 124 and blown out of the casing by the fan 16, making the air guide smoother and helping to improve the heat dissipation efficiency.

[0053] like Figure 3 As shown, the air inlet 124 extends vertically, preferably extending to the bottom end of the connecting plate 122, and the notch 125 extends horizontally. The length of the notch 125 is set according to actual needs and should not be too long to avoid reducing the overall structural strength of the middle partition 12. The shape of the air inlet 124 can be set according to actual needs, for example Figure 3 An approximately semicircular shape is shown, which can optimize the air suction effect as much as possible while ensuring the overall structural strength of the middle partition 12.

[0054] As a preferred embodiment of the present application, a blocking piece 126 is provided at one end of the first step portion 123 to limit the movement of the fan 16 in the horizontal direction.

[0055] When the fan 16 is disassembled and assembled, the fan 16 can be pushed to or pulled out of the first step portion 123 in the horizontal direction. This can avoid difficulties in disassembling and assembling the fan 16 when there is insufficient space above the fan 16, making the disassembly and assembly of the fan 16 more flexible, which is beneficial for later maintenance and simplifies the disassembly and assembly process. When installing the fan 16, the baffle 126 can provide a horizontal limit to prevent the fan 16 from being pushed too far, thereby improving installation efficiency and preventing the fan 16 from shaking in the horizontal direction to improve its stability in use.

[0056] like Figure 3 As shown, the blocking piece 126 is perpendicular to the first step portion 123 , and the height of the blocking piece 126 can be set according to actual needs. For example, the blocking piece 126 extends upward to the same height as the main board 121 to enhance the stopping effect.

[0057] As a preferred embodiment of the present application, the middle partition 12 further includes a second step portion 127 bent downward from the first step portion 123 , and the heat dissipation assembly further includes a radiator 17 , and the radiator 17 is installed on the second step portion 127 .

[0058] like Figure 3 As shown, the second step portion 127 is lower than the first step portion 123, and the radiator 17 is arranged on the second step portion 127, which is lower than the bottom end of the fan 16, and can meet the layout requirements of the radiator 17 with a larger height. By rationally utilizing the space on the side of the mainboard 121, the compactness of the layout of various components is improved.

[0059] It is understandable that in other embodiments, the second step portion 127 may be omitted, and the fan 16 and the radiator 17 may be arranged side by side on the first step portion 123 by widening the first step portion 123 .

[0060] As a preferred embodiment of the present application, an upper baffle 111 extending inward is provided on the inner wall of the rear cover 11 , and the upper baffle 111 is provided above the first step portion 123 to limit the axial installation position of the fan 16 .

[0061] By setting the upper baffle 111, the upper baffle 111 and the first step portion 123 can be used to limit the fan 16 in the vertical direction, which can reduce the shaking or tipping of the fan 16 during use and improve the stability of installation and use; and the upper baffle 111 can prevent dust from above from falling onto the fan 16 and being sucked into the fan 16, thereby playing a certain dust protection role.

[0062] like Figure 1 As shown, the upper baffle 111 is directly above the first step portion 123 , and when the fan 16 is installed in place, the top of the fan 16 may or may not be in contact with the inner surface of the upper baffle 111 .

[0063] Furthermore, a side baffle 112 bent downward is provided at the end of the upper baffle 111, and the side baffle 112 is used to limit the forward tilting of the fan 16. Specifically, when the fan 16 is installed in place, the inner surface of the side baffle 112 fits the front end surface of the fan 16 or there is a certain gap between the two, so as not to affect the operation of the fan blades of the fan 16.

[0064] Further, such as Figure 5 As shown, the upper baffle 111 includes a first plate 113 directly opposite to the second step portion 127 and a second plate 114 directly opposite to the first step portion 123. The first plate 113 and the second step portion 127 can limit the radiator 17 in the vertical direction. When the radiator 17 is high, the first plate 113 and the second plate 114 can form a stepped distribution, and the first plate 113 is higher than the second plate 114.

[0065] In order to achieve the fixation of the middle partition plate 12 and the front cover 10 and the rear cover 11, the middle partition plate 12 and the front cover 10 and the rear cover 11 can be fixed by screws or buckles.

[0066] For example, in one embodiment, a slot 128 is provided at one end of the middle partition 12 away from the connecting plate 122, and a buckle 101 is provided on the inner wall of the front cover 10 to engage with the slot 128, so as to fix the middle partition 12 to the front cover 10. Specifically, in one embodiment, the buckle 101 is bent upward, and the buckle 101 passes through the slot 128 from the lower surface of the middle partition 12 to fix the middle partition 12. In another embodiment, Figure 4 and Figure 8 As shown, the buckle 101 is bent downward (inverted L-shaped), and the buckle 101 passes through the slot 128 from the upper surface of the middle partition 12; in order to ensure the fixing effect of the middle partition 12, in this embodiment, a support column 21 is further fixed between the bottom plate 19 of the shell and the middle partition 12 to provide a stable support for the middle partition 12. Figure 3 and Figure 8 As shown, the middle partition 12 is provided with a downwardly folded flange 129, and the opening range of the slot 128 can extend from the main plate 121 to the upper end of the flange 129, so that the buckle 101 can pull the flange 129 toward the front cover 10, thereby optimizing the fixing effect of the middle partition 12.

[0067] In one embodiment, if Figure 3 and Figure 6 As shown, a vertical mounting surface 130 is provided at one end of the middle partition 12 close to the rear cover 11, and a screw hole 202 is provided on the mounting surface 130. Correspondingly, the rear cover 11 is also provided with a screw hole 202, and the middle partition 12 and the rear cover 11 can be fixed by inserting screws.

[0068] As a preferred embodiment of the present application, the outer shell includes a bottom plate 19, and a support column 21 is connected between the middle partition plate 12 and the bottom plate 19, and the upper and lower end surfaces of the support column 21 are provided with screw holes 202, and the middle partition plate 12 and the bottom plate 19 are provided with through holes 203 corresponding to the screw holes 202.

[0069] By providing the support column 21, the stability of the support of the middle partition 12 can be improved, so that the water storage bladder 15 can be placed on the middle partition 12, and the firmness and stability of the use of the middle partition 12 can be enhanced by locking the screws.

[0070] like Figure 1 As shown, during installation, the support column 21 is first supported on the base plate 19, and then screws are driven through the lower surface of the base plate 19 to fix the support column 21 to the base plate 19, and then the through hole 203 of the middle partition 12 is aligned with the screw hole 202 at the upper end of the support column 21, and screws are driven through the upper surface of the middle partition 12 to fix the support column 21 to the middle partition 12.

[0071] Preferably, the support column 21 is in an elongated strip shape along a direction perpendicular to the line connecting the front cover 10 and the rear cover 11 , and a plurality of separated heat dissipation cavities 211 are provided inside the support column 21 .

[0072] By adopting the long strip support column 21, the support range can be increased while reducing the number of support columns 21 used, further improving the support effect of the middle partition 12, and multiple heat dissipation cavities 211 are arranged in the support column 21, which can utilize the cavity to dissipate heat and improve the heat dissipation effect.

[0073] like Figure 1 and Figure 7 As shown, a support column 21 is used to fix the middle area of ​​the middle partition 12 and the bottom plate 19. Two screw holes 202 are provided at the upper and lower ends of the support column 21 to achieve a secure fixation. The support column 21 is designed to be hollow to facilitate heat dissipation. Adjacent heat dissipation cavities 211 are separated by isolation ribs, which increases the heat dissipation area while ensuring that the support column 21 has a certain structural strength to support the middle partition 12.

[0074] It is understandable that in other embodiments, the support column 21 may also adopt a simple cylindrical, prism or other structure. When a single support column 21 is thinner, multiple support columns 21 may be evenly distributed to ensure the supporting effect.

[0075] Furthermore, at least one of the front wall surface and the rear wall surface of the support column 21 is provided with a convex rib 212 protruding outward.

[0076] like Figure 7 As shown, by setting the convex rib 212, on the one hand, it can form a form similar to a heat sink, increase the heat dissipation area, and enhance heat dissipation; on the other hand, it can enhance the structural strength of the support column 21, which is beneficial to improving the supporting stability of the middle partition 12.

[0077] As a preferred embodiment of the present application, the shell has a shell top wall and shell side walls connected to both sides of the shell top wall, at least one of the shell side walls is provided with an air inlet 22, and the back cover 11 is provided with an air outlet 23.

[0078] like Figure 1 As shown, the shell includes a main shell 18, which is a three-sided structure connected to the top wall of the shell and two opposite side walls of the shell. When the machine is working to dissipate heat, cold air enters the shell from the side air inlet 22. After heat exchange, under the action of the fan 16, hot air is blown out from the rear air outlet 23, ensuring the heat dissipation effect.

[0079] The air inlet holes 22 and the air outlet holes 23 may be arranged in a matrix to ensure air inlet and outlet efficiency.

[0080] Furthermore, the distribution range of the plurality of air inlet holes 22 may be optimized according to the position of the fan 16 , for example, at least some of the air inlet holes 22 are within the height range of the fan 16 , so that the fan 16 can efficiently absorb air and improve heat dissipation efficiency.

[0081] Similarly, the distribution of the air outlet holes 23 may also refer to the position of the fan 16 , for example, at least part of the air outlet holes 23 are within the height range of the fan 16 , so as to shorten the exhaust path and improve the heat dissipation efficiency.

[0082] The technical solution protected by the present utility model is not limited to the above-mentioned embodiments. It should be pointed out that the combination of the technical solution of any embodiment with the technical solution of one or more other embodiments is within the protection scope of the present utility model. Although the present utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to it based on the present utility model. Therefore, these modifications or improvements made without departing from the spirit of the present utility model are within the scope of protection claimed by the present utility model.
