[0035] The existing compressor refrigeration cold tank is equipped with water level detection, water inlet and outlet, drain pipe, exhaust pipe, etc., which makes its internal structure complicated, and the exhaust pipe is connected to the outside, which easily causes secondary contamination in the cold tank.
[0036] In view of this, the present invention provides a refrigeration device 100 .
[0037] See also Figures 1 to 3 In one embodiment of the utility model, the refrigeration device 100 includes a tank body 2 and an evaporator 5, wherein a water storage space 210 is formed in the tank body 2, and a water inlet pipe 24 and a water outlet pipe 23 are installed on one side of the tank body 2; the evaporator 5 is sleeved on the outer periphery of the tank body 2; wherein the water outlet pipe 23 includes an outer pipe section 231 exposed from the tank body 2 and an inner pipe section 232 extending into the tank body 2, and an exhaust hole 233 is opened in the inner pipe section 232 near the outer pipe section 231.
[0038] It should be noted that Figure 1 The tank body 2 is wrapped by a heat preservation layer. The refrigeration device 100 includes at least the tank body 2 and the evaporator 5. In addition, the refrigeration device 100 should also include a condenser 4, a bracket 12, a compressor 3 and a fan (not shown). The tank body 2 is installed above the bracket 12, and the tank body 2 and the bracket 12 are fixedly connected. The specific connection method can be screw connection, of course, it can also be other fixed connection methods. The bracket 12 is installed on a base 11, the condenser 4 is fixed to the base 11, the compressor 3 is located above the condenser 4, and a fan is provided below the condenser 4 to dissipate heat from the condenser 4.
[0039] Among them, the evaporator 5 is mounted on the outer periphery of the tank body 2, and the evaporator 5 is used to exchange heat for the water flow inside the tank body 2. The shape of the tank body 2 can be cylindrical or square, which is not specifically limited here, and the shape of the evaporator 5 matches the outer periphery of the tank body 2.
[0040] Specifically, a water inlet pipe 24 for injecting water into the water storage space 210 and a water outlet pipe 23 for discharging water from the water storage space 210 are installed on the tank body 2, wherein the water inlet pipe 24 and the water outlet pipe 23 can be installed on the same side of the tank body 2, or on different sides of the tank body 2. An exhaust hole 233 is provided on the inner pipe section 232 of the water outlet pipe 23, and the exhaust hole 233 is used to discharge the gas in the water storage space 210. In this way, the pipeline structure of the tank body 2 can be simplified, and the water storage space 210 in the tank body 2 can be prevented from being polluted again.
[0041] The technical solution of the present invention simplifies the piping structure of the tank body 2 of the refrigeration device 100 by providing an exhaust hole 233 on the water outlet pipe 23, thereby replacing the original solution of separately providing the water outlet pipe 23 and the exhaust pipe. The exhaust hole 233 is connected to the water outlet channel instead of being connected to the external space of the tank body 2, which can avoid the water source in the water storage space 210 in the tank body 2 from being contaminated secondary, thereby improving the cleanliness of the water source inside the tank body 2.
[0042] In one embodiment, see Figure 4 and Figure 6 The number of the exhaust holes 233 is set to two, and the two exhaust holes 233 are arranged opposite to each other on the inner tube section 232.
[0043] It should be noted that, considering that one exhaust hole 233 cannot meet the exhaust requirements of the tank body 2 when water is filled, two exhaust holes 233 are provided on the inner tube section 232, and the two exhaust holes 233 are arranged opposite to each other, that is, the openings of the two exhaust holes 233 are opposite to each other, so that the process flow of opening the two exhaust holes 233 can be simplified. Of course, in other embodiments, the two exhaust holes 233 may not be arranged opposite to each other, and the distances from the two exhaust holes 233 to the top of the water outlet space may be the same, or the distances from the two exhaust holes 233 to the top of the water storage space 210 may be different.
[0044] In one embodiment, see Figure 6 The distance from the exhaust hole 233 to the top of the water storage space 210 is D1, and the distance from the exhaust hole 233 to the bottom of the water storage space 210 is D2, and D1 and D2 satisfy 0.03≤D1 / D2≤0.2.
[0045] According to the above embodiment, the exhaust hole 233 is close to the outer tube section 231, that is, the distance from the exhaust hole 233 to the top of the water storage space 210 is less than the distance from the exhaust hole 233 to the bottom of the water storage space 210, that is, D1 is less than D2. Further, considering that when water enters the tank body 2, the air will be squeezed to the top of the water storage space 210, so D1 cannot be too large, otherwise it is difficult to smoothly discharge the air above the water storage space 210, so D1 / D2 is set to be less than or equal to 0.2; of course, D1 should not be set too small, otherwise in the process of installing the water outlet pipe 23, the exhaust hole 233 is easily located outside the tank body 2 due to improper installation, so D1 / D2 should be greater than or equal to 0.03.
[0046] In one embodiment, please continue to refer to Figure 6 , the D1 satisfies 2mm≤D1≤20mm.
[0047] It should be noted that, considering that when water flows into the water storage space 210, the air will be squeezed to the top of the water storage space 210 by the water, so D1 cannot be set too large, otherwise it is difficult to smoothly discharge the air above the water storage space 210, so D1 is set greater than or equal to 2mm; of course, D1 should not be set too small, otherwise during the installation of the water outlet pipe 23, the exhaust hole 233 may not be installed properly and easily be located outside the tank body 2, so D1 is set less than or equal to 20mm.
[0048] In one embodiment, see Figure 3 The water inlet pipe 24 has a pipe mouth 241 facing the water storage space 210, and a water retaining member 27 is provided in the water storage space 210 corresponding to the pipe mouth 241. The water retaining member 27 is connected to the tank body 2, and the water retaining member 27 is used to reduce the flow rate of the incoming water.
[0049] Specifically, the pipe mouth 241 faces the water storage space 210, and the water flowing through the water inlet pipe 24 flows into the water storage space 210 through the pipe mouth 241. Considering that the water flowing directly from the water inlet pipe 24 into the bottom of the water storage space 210 will result in a shorter refrigeration heat exchange time, thereby making the outlet temperature of the cold water relatively high, a water retaining member 27 is provided corresponding to the pipe mouth 241. The water retaining member 27 is used to block the water flowing in from the pipe mouth 241 to prevent the water flow from being too fast, thereby causing a poor refrigeration effect.
[0050] In one embodiment, see Figure 2 and Figure 8 The tank body 2 includes a cover plate 22 and a tank body 21 connected to each other, the water inlet pipe 24 and the water outlet pipe 23 are installed on the cover plate 22, the water retaining member 27 is connected to the cover plate 22, the tank body 21 has a plurality of side walls 211, and the water retaining member 27 is spaced apart from the side walls 211.
[0051] It should be noted that the tank body 2 includes a connected cover plate 22 and a tank body 21, the cover plate 22 is located on the upper side of the tank body 21, and the water inlet pipe 24 and the water outlet pipe 23 are both installed on the cover plate 22. Of course, in other embodiments, the water inlet pipe 24 and the water outlet pipe 23 can also be installed on the tank body 21. Furthermore, the water retaining member 27 is connected to the cover plate 22, and the tank body 21 has a plurality of side walls 211 parallel to the length direction of the water outlet pipe 23 (i.e., the axial direction of the water outlet pipe 23), and the water retaining member 27 and the side walls 211 are spaced apart. Specifically, the water retaining member 27 and the side walls 211 close to it are spaced apart. The water retaining member 27 and a certain side wall 211 close to the water retaining member 27 may be spaced apart, or the water retaining member 27 and a plurality of side walls 211 close to the water retaining member 27 may be spaced apart. No specific limitation is made herein. In this way, the water flowing into the water retaining member 27 can flow into the bottom of the water storage space 210 through the gap between the water retaining member 27 and the side walls 211.
[0052] In one embodiment, see Figure 7 The water retaining member 27 is arranged in a step shape, and the water retaining member 27 includes a fixing plate 272, a water retaining plate 271 and a connecting plate 273. The fixing plate 272 and the water retaining plate 271 are connected via the connecting plate 273, and the fixing plate 272 is fixed to the cover plate 22.
[0053] Specifically, the water retaining member 27 is arranged in a step shape as a whole, so that the water retaining member 27 can be connected to the cover plate 22, and the structure of the water retaining member 27 for blocking the water flow has a certain distance from the cover plate 22. Therefore, the water retaining member 27 at least includes a fixed plate 272, a water retaining plate 271 and a connecting plate 273, wherein the connecting plate 273 connects the fixed plate 272 and the water retaining plate 271 respectively. In this embodiment, the connecting plate 273 is perpendicular to the fixed plate 272, and the connecting plate 273 is perpendicular to the water retaining plate 271. Of course, the angle between the connecting plate 273 and the fixed plate 272 and the angle between the connecting plate 273 and the water retaining plate 271 can be less than 90°, and the angle between the connecting plate 273 and the fixed plate 272 and the angle between the connecting plate 273 and the water retaining plate 271 can be greater than 90°.
[0054] In one embodiment, please continue to refer to Figure 7 The water baffle plate 271 is provided with a plurality of water holes 271a at intervals.
[0055] It should be noted that the water baffle 271 is provided with a plurality of water holes 271a at intervals. Considering that the water flow entering from the water inlet pipe 24 is too large, in order to prevent the water baffle 271 from being subjected to a large water flow pressure, a plurality of water holes 271a are provided at intervals on the water baffle 271, so that the water flow can flow into the bottom of the water storage space 210 through the plurality of water holes 271a. In this embodiment, the water holes 271a are arranged in an array, and the water holes 271a are provided as round holes, but are not limited thereto. The water holes 271a may also be provided as square holes, or as irregular holes.
[0056] In one embodiment, see Figure 2 The tank body 21 has a bottom corresponding to the cover plate 22, and a drain pipe 25 is installed on the bottom. The drain pipe 25 is used to open and discharge sewage in the cleaning mode.
[0057] It should be noted that, considering that impurities such as scale will settle at the bottom of the tank body 2 after storing water for a long time, the refrigeration device 100 also has a cleaning function. When the cleaning function is turned on, the drain pipe 25 located at the bottom of the tank body 21 is opened (its opening and closing is controlled by a valve), so that the flushing sewage is discharged from the drain pipe 25. In this way, the environment inside the tank body 21 can be kept in a relatively clean state.
[0058] In one embodiment, see Figure 4 and Figure 5 The aperture of the exhaust hole 233 is R1, the inner diameter of the inner tube section 232 is R2, and R1 and R2 satisfy R1≤0.2R2.
[0059] Specifically, it should be noted that in order to ensure that the water flow in the inner pipe section 232 will not flow out from the exhaust hole 233, the aperture of the exhaust hole 233 should be smaller, at least significantly different from the aperture of the water outlet of the outlet pipe 23 (the inner diameter of the inner pipe section 232). Therefore, R1 and R2 are set to satisfy R1≤0.2R2. Within this range, the water flow in the inner pipe section 232 will only flow out from the water outlet of the outlet pipe 23, and due to the influence of the surface tension of the water flow, it cannot flow out from the exhaust hole 233 with a very small aperture.
[0060] In one embodiment, see Figure 2 The tank body 2 is arranged in a square shape.
[0061] It should be noted that, compared with the case where the tank body 2 is set as a cylinder, the tank body 2 is set in a square shape (i.e., a right quadrangular prism), and the tank body 2 has a larger surface area, which can increase the heat exchange area of the evaporator 5 and improve the heat exchange efficiency of the evaporator 5. Secondly, the tank body 2 is set in a square shape to match the shape of the shell of the drinking water device accommodating the refrigeration device 100, so that the tank body 2 has a larger volume in a limited space.
[0062] The utility model also proposes a drinking water device, which includes a refrigeration device 100, and the refrigeration device 100 includes a tank body 2 and an evaporator 5. A water storage space 210 is formed in the tank body 2, and a water inlet pipe 24 and a water outlet pipe 23 are installed on one side of the tank body 2; the evaporator 5 is sleeved on the outer periphery of the tank body 2; wherein the water outlet pipe 23 includes an outer pipe section 231 exposed from the tank body 2 and an inner pipe section 232 extending into the tank body 2, and the inner pipe section 232 is provided with an exhaust hole 233 near the outer pipe section 231.
[0063] The utility model also proposes a drinking water device, which includes a refrigeration device 100. The specific structure of the refrigeration device 100 refers to the above embodiment. Since the drinking water device adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.
[0064] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
