When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0044] With the development of the drinking water equipment 100, the functions thereof are increasing. The drinking water equipment 100 comprises a compressor 3, a condenser 4 and an evaporator 5 to realize the refrigeration function of the drinking water equipment 100. Since there are many pipelines between the compressor 3, the condenser 4 and the evaporator 5, the refrigerant pipelines in the drinking water equipment 100 are numerous and complicated, which to a certain extent occupies more installation space 120 in the drinking water equipment 100, which is not conducive to the miniaturization of the drinking water equipment 100. Furthermore, the spatial adaptability and production efficiency of the drinking water equipment 100 are easily affected.

[0045] In order to solve this technical problem, the utility model proposes a drinking water device 100. It should be noted that the drinking water device 100 can be specifically configured as a device with a refrigeration function such as a water purifier and a water dispenser to meet the user's cold water needs.

[0046] See also Figures 1 to 4In one embodiment of the utility model, the drinking water equipment 100 includes a base 11, a bracket 12, a compressor 3, a tank body 2, an evaporator 5, a condenser 4, a second refrigerant outflow pipe 53 and a capillary tube 54; the bracket 12 is fixedly connected to the base 11, and an installation space 120 is formed between the base 11 and the bracket 12; the compressor 3 is arranged in the installation space 120 and is connected to the base 11; the tank body 2 is arranged outside the installation space 120; the evaporator 5 is connected to the outer periphery of the tank body 2; the condenser 4 is arranged in the base 11 and is connected to the compressor 3; the second refrigerant outflow pipe 53 connects the evaporator and the compressor 3; one end of the capillary tube 54 is connected to the condenser 4, and the other end passes through the installation space 120 and is connected to the evaporator 5, and the capillary tube 54 includes a spiral section 541, and the spiral section 541 is sleeved on the outside of the second refrigerant outflow pipe 53 to improve the miniaturization level of the drinking water equipment 100.

[0047] In the technical solution of the utility model, the evaporator 5 and the condenser 4 are respectively arranged on the upper and lower sides of the compressor 3, so that the components are arranged along the height direction of the drinking water equipment 100, which can effectively reduce the space occupied by the drinking water equipment 100 in the horizontal direction, thereby improving the miniaturization level of the drinking water equipment 100.

[0048] By sleeve the capillary tube 54 on the outer periphery of the second refrigerant outlet pipe 53 through the spiral section 541, on the one hand, the space occupied by the capillary tube 54 and the second refrigerant outlet pipe 53 in the drinking water equipment 100 is reduced, thereby improving the integration level of the internal refrigerant pipeline and further improving the miniaturization level of the drinking water equipment 100, which helps to improve the spatial adaptability of the drinking water equipment 100 so that the drinking water equipment 100 can be applied to related equipment with refrigeration requirements, which helps to improve production efficiency and reduce production costs; on the other hand, under normal operating conditions, because the temperature at the capillary tube 54 is lower than the temperature at the second refrigerant outlet pipe 53, the capillary tube 54 is arranged outside the second refrigerant outlet pipe 53, so that reliable heat exchange can occur, thereby reducing the refrigerant temperature in the second refrigerant outlet pipe 53 and improving the energy consumption of the rear-end compressor 3. At the same time, it can reliably ensure that the flash gas generated by the refrigerant during or after throttling in the capillary tube 54 is as little as possible, which helps to improve the heat exchange efficiency of the evaporator 5.

[0049] Specifically, the inner diameter of the capillary tube 54 is relatively small, so that the refrigerant flowing out of the condenser 4 can be further condensed to reduce the generation of flash gas. At the same time, it can control the flow rate of refrigerant entering the evaporator 5 to improve the heat exchange efficiency of the evaporator 5, thereby helping to reduce the content of liquid refrigerant entering the compressor 3 and reduce the possibility of liquid hammer caused by the refrigerant entering the compressor 3.

[0050] The capillary tube 54 includes a spiral section 541, which helps to reduce the space occupied by the capillary tube 54 and provides space for the second refrigerant outlet pipe 53 to pass through, thereby reducing the space occupied by both the capillary tube 54 and the second refrigerant outlet pipe 53. In addition, since the capillary tube 54 is arranged along the circumference of the second refrigerant outlet pipe 53, the heat exchange area can be increased to a certain extent, thereby improving the heat exchange efficiency.

[0051] Since the evaporator 5 and the condenser 4 are arranged at intervals along the vertical direction of the compressor 3, and the compressor 3 is located between the evaporator 5 and the condenser 4, the lateral size of the drinking water device 100 can be reduced, and the drinking water device 100 can be miniaturized. Among them, the evaporator 5 is located above the compressor 3, and the condenser 4 is located below the compressor 3. The refrigerant in the capillary tube 54 flows from bottom to top, and the refrigerant in the second refrigerant outflow pipe 53 flows from top to bottom; and the evaporator 5 is sleeved on the outer periphery of the tank body 2, so that the heat exchange surface of the evaporator 5 can be fitted with the outer peripheral surface of the tank body 2, and there is a large heat exchange area between the tank body 2 and the evaporator 5, so that the refrigerant in the evaporator 5 can fully absorb the heat of the liquid in the tank body 2, so as to achieve the purpose of rapid cooling, improve the heat exchange efficiency of the evaporator 5, and meet the cold water needs of users.

[0052] The drinking water equipment 100 also includes a base 11 and a bracket 12 connected to the base 11, which is convenient for forming an installation space 120 for assembling the compressor 3 and related refrigerant pipes, and can also separate the compressor 3 and the tank body 2, reducing the possibility of heat exchange between the heat in the installation space 120 and the tank body 2; wherein, the bracket 12 is arched, the compressor 3 is installed on the base 11, and the condenser can be embedded in the base 11, which can reasonably utilize the space in the base 11 to a certain extent, improve the integration, and further reduce the volume of the drinking water equipment 100, and realize the miniaturization of the drinking water equipment 100. A heat dissipation gap is left between the compressor 3 and the condenser 4, which is convenient for reliable heat dissipation of the condenser 4 and improves the safety of the use of the compressor 3 and the condenser 4. Of course, the condenser 4 can be set on the upper surface of the base 11, when the condenser 4 is embedded in the base 11.

[0053] Specifically, the compressor 3 can be fixed on the base 11 by a tripod 34, which is convenient for simplifying the assembly steps of the compressor 3 and improving the assembly efficiency. The tripod 34 includes a foot plate 34a for supporting and fixing the compressor 3, and a foot pad 34b connecting the base 11 and the foot plate 34a. The foot pad 34b has elastic deformation ability to absorb the vibration generated during the operation of the compressor 3, and the foot pad 34b can make the base 11 and the foot plate 34a relatively fixed by means of plug-in, bolt connection, etc. The foot pad 34b can be specifically configured as a shock absorber.

[0054] See also Figure 4In the embodiment of the utility model, the gap between the inner wall of the spiral section 541 and the second refrigerant outlet pipe 53 is s, 0mm≤s≤10mm, so as to ensure that the space occupied by the capillary tube 54 and the second refrigerant outlet pipe 53 is as small as possible; specifically, when the gap between the inner wall of the spiral section 541 and the second refrigerant outlet pipe 53 is 0, the capillary tube 54 completely wraps the second refrigerant outlet pipe 53. At this time, the effective contact area between the two is the largest, the heat exchange efficiency is high, and the occupied space is minimized; and when the gap between the inner wall of the spiral section 541 and the second refrigerant outlet pipe 53 is 0, the capillary tube 54 completely wraps the second refrigerant outlet pipe 53. At this time, the effective contact area between the two is the largest, the heat exchange efficiency is high, and the occupied space is minimized; When the gap between the outlet pipes 53 is greater than 10 mm, it is not conducive to reducing the occupied space of the capillary tube 54 and the second refrigerant outlet pipe 53 in the drinking water equipment 100, and is also not conducive to the refrigeration treatment of the refrigerant loop pipe by the capillary tube 54; therefore, the gap between the inner wall of the spiral section 541 and the second refrigerant outlet pipe 53 is limited to between 0 mm and 10 mm, which can not only minimize the occupied space of the capillary tube 54 and the second refrigerant outlet pipe 53, but also ensure the refrigeration treatment of the refrigerant loop pipe by the capillary tube 54, which helps to reduce the energy consumption of the rear-end compressor 3.

[0055] Among them, the specific value of the gap between the inner wall of the spiral section 541 and the second refrigerant outlet pipe 53 includes but is not limited to 0mm, 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, and 10mm.

[0056] Specifically, in the embodiment of the utility model, the inner diameter of the capillary tube 54 is r, 0.5mm≤r≤1.5mm, so as to ensure the condensation effect and throttling effect of the capillary tube 54; specifically, in the extension direction of the capillary tube 54, the inner diameter of the capillary tube 54 remains consistent, so as to ensure the flow of the refrigerant in the capillary tube 54 and the realization of the corresponding effect; when the inner diameter of the capillary tube 54 is less than 0.5mm, it is easy to reduce the refrigerant flow rate entering the evaporator 5, thereby affecting the heat exchange effect of the evaporator 5; when the inner diameter of the capillary tube 54 is greater than 1.5mm, it is easy to increase the overall volume of the capillary tube 54, and at the same time, it is easy to increase the flash gas, thereby affecting the heat exchange efficiency of the evaporator 5; therefore, setting the inner diameter of the capillary tube 54 between 0.5mm and 1.5mm can not only further condense the refrigerant flowing out of the condenser 4 and reduce the generated flash gas, but also reliably control the refrigerant flow rate entering the evaporator 5 to improve the heat exchange efficiency of the evaporator 5. In this embodiment, the inner diameter of the capillary tube 54 is 1 mm, and the wall thickness of the capillary tube 54 is 0.5 mm.

[0057] Among them, the specific value of the inner diameter of the capillary tube 54 includes but is not limited to 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, and 1.5mm.

[0058] Specifically, in an embodiment of the present utility model, the outer diameter of the second refrigerant outlet pipe 53 is R, 4mm≤R≤10mm. On the basis of ensuring reliable reflux of the refrigerant, the volume of the second refrigerant outlet pipe 53 is reduced. Specifically, when the outer diameter of the second refrigerant outlet pipe 53 is less than 4mm, it is easy to extend the time for the refrigerant to return to the compressor 3. When the outer diameter of the second refrigerant outlet pipe 53 is greater than 10mm, it is easy to increase the volume of the second refrigerant outlet pipe 53, affecting miniaturization. Therefore, the outer diameter of the second refrigerant outlet pipe 53 is limited to between 4mm and 10mm, which can not only ensure the reflux efficiency of the refrigerant, but also reduce the volume of the second refrigerant outlet pipe 53. Combined with 0mm≤s≤10mm, it is helpful to achieve the miniaturization of the drinking water equipment 100.

[0059] Among them, the specific value of the outer diameter of the second refrigerant outlet pipe 53 includes but is not limited to 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, and 10mm.

[0060] Optionally, in an embodiment of the utility model, the second refrigerant outlet pipe 53 extends along the up and down directions of the compressor 3 and is located on the side of the compressor 3. Such a configuration is convenient for the winding of the capillary tube 54 and for the rational use of the side space of the compressor 3. It can be understood that the refrigerant in the second refrigerant outlet pipe 53 flows from bottom to top, or from top to bottom, wherein the second refrigerant outlet pipe 53 may include a first pipe section and a second pipe section laterally connected to the first pipe section, the first pipe section is connected to the evaporator 5, and the second pipe section is connected to the compressor 3. The spiral section 541 is sleeved on the first pipe section and / or the second pipe section to facilitate the support of the spiral section 541 to reduce the possibility of displacement and deformation of the spiral section 541; of course, the second refrigerant outlet pipe 53 may also be arranged to be tilted as a whole.

[0061] See also Figure 2 In an embodiment of the utility model, a drying filter 8 is connected between the capillary tube 54 and the condenser 4. The drying filter 8 is arranged close to the capillary tube 54 and extends in the up-down direction of the compressor 3. Thus, by arranging the drying filter 8 upstream of the capillary tube 54, impurities entering the capillary tube 54 are reduced, and the possibility of blockage of the capillary tube 54 is reduced to avoid functional failure of the capillary tube 54, thereby facilitating the smooth flow of the refrigerant. In addition, since the drying filter 8 is arranged near the capillary tube 54, the compactness of the drying filter 8 and the capillary tube 54 is achieved, which helps to reduce space occupancy and facilitates the miniaturization of the drinking water device 100.

[0062] Specifically, the angle between the filter drier 8 and the compressor 3 in the vertical direction is θ, 0°≤θ≤45°. In this way, the filter drier 8 can be placed as close to the capillary 54 as possible while ensuring the normal operation of the filter drier 8. It can be understood that Figure 2 As shown, the filter drier 8 is parallel to the vertical extension direction of the compressor 3, so that the filter drier 8 can be arranged as close to the capillary tube 54 as possible to improve the compactness level; Figure 3 As shown, the dry filter 8 can also be arranged as a whole with an inclination, that is, there is an angle θ between the dry filter 8 and the upper and lower directions of the compressor 3, θ is greater than 0° and less than or equal to 45°, compared with the horizontal placement of the dry filter 8, the lateral space occupied can be reduced to a certain extent.

[0063] See also Figures 2 to 3 In an embodiment of the utility model, the bracket 12 includes a mounting plate 126, and the mounting plate 126 is spaced above the compressor 3. The tank body 2 is fixed to the side of the mounting plate 126 away from the compressor 3. It can be understood that the tank body 2 is arranged on the side of the mounting plate 126 away from the compressor 3, that is, it is arranged outside the installation space 120, which can not only ensure the reliable assembly of the tank body 2, but also reduce the possibility of heat exchange between the heat in the installation space 120 and the tank body 2, thereby reducing heat interference. The spacing between the mounting plate 126 and the compressor 3 can reduce the possibility of interference between the components such as the plug board 28 extending into the installation space 120 and the compressor 3.

[0064] Specifically, Figure 3 As shown, the mounting plate 126 is provided with an avoidance notch 125 for avoiding the capillary tube 54 and the second refrigerant outlet pipe 53, so as to ensure that the extension of the capillary tube 54 and the second refrigerant outlet pipe 53 is not interfered by the mounting plate 126; the avoidance notch 125 can be formed at the edge of the mounting plate 126, and can also be set away from the edge of the mounting plate 126.

[0065] Furthermore, in an embodiment of the utility model, the tank body 2 is coated with an insulation box 7, and the insulation box 7 is provided with an avoidance hole 711 corresponding to the avoidance notch 125, that is, the avoidance hole 711 can be used for the passage of the capillary tube 54 and the second refrigerant outlet pipe 53. On the one hand, by cooperating with the insulation box 7 and the evaporator 5, the cold water in the tank body 2 is always in a low temperature state, and it helps to reduce energy consumption; on the other hand, by opening the avoidance hole 711, the capillary tube 54 and the second refrigerant outlet pipe 53 pass through the avoidance hole 711, thereby realizing the connection between the evaporator 5 and the condenser 4, and the connection between the evaporator 5 and the compressor 3. The avoidance hole 711 can be provided at the bottom of the heat preservation box 7. In this case, the heat preservation box 7 is matched with the second refrigerant outlet pipe 53 to cover the second refrigerant outlet pipe 53 to ensure the heat exchange effect; or, the avoidance hole 711 can be provided at the bottom and adjacent side of the heat preservation box 7. In this case, due to the radial size of the second refrigerant outlet pipe 53, part of the avoidance hole 711 provided at the side exposes the second refrigerant outlet pipe 53, which is convenient for the processing of the heat preservation box 7. Optionally, the heat preservation box 7 is made of foam material.

[0066] The avoidance gap 125 is opened corresponding to the avoidance hole 711 , so that the avoidance gap 125 can be located directly below the avoidance hole 711 , thereby allowing the pipeline to be installed with a shorter length, thereby simplifying the structures of the capillary tube 54 and the second refrigerant outlet pipe 53 .

[0067] See also Figure 3 In the embodiment of the utility model, the mounting plate 126 is provided with a plug hole 121, and the bottom of the tank body 2 is provided with a plug plate 28 plugged with the plug hole 121, wherein the plug hole 121 is a through hole, and the connection method between the plug plate 28 and the tank body 2 includes but is not limited to welding, bonding, and clamping. The plug plates 28 correspond to the plug holes 121 one by one, and there are multiple arrays, which helps to improve the installation stability of the tank body 2. In addition, when an insulation box 7 is provided outside the tank body 2, the plug plate 28 passes through the insulation box 7 to ensure the connection between the plug plate 28 and the mounting plate 126.

[0068] Furthermore, in order to further improve the stability of installation, in the embodiment of the utility model, the tank body 2 is connected to the mounting plate 126 by fasteners, and the fasteners can be configured with bolts, latches, etc., wherein the edge of the insertion hole 121 is provided with a downwardly bent flange plate 122, and when the plug plate 28 is inserted into the insertion hole 121, the plug plate 28 fits with the flange plate 122, and then, the assembly of the tank body 2 can be achieved by fasteners penetrating the plug plate 28 and the flange plate, and after the assembly is completed, an assembly gap is left between the tank body 2 and the mounting plate 126, which is convenient for the installation of the insulation box 7. However, in other embodiments, of course, the plug plate 28 can also be bent to be stuck in the insertion hole 121, or the plug plate 28 can be embedded with a holder set on the mounting plate 126 to achieve the same effect of strengthening the connection.
