Description

Technical Field

[0001] The present application relates to the field of household appliance technology, and in particular to a cold tank assembly and a water dispenser having the assembly. Background Art

[0002] Water dispensers can heat and cool water. In the hot summer, refrigerated water dispensers provide great convenience for people.

[0003] In the related technology, a compressor-type refrigerated water dispenser usually uses a cold tank assembly to make cold water. The cold tank assembly includes a cold tank, an evaporator, a compressor, a condenser and a capillary tube. The evaporator tube is wrapped around the outside of the cold tank. The refrigerant in the evaporator tube cools the water in the cold tank. One end of the evaporator tube is connected to the compressor. The compressor absorbs the refrigerant vapor in the evaporator tube and compresses it into a high-temperature, high-pressure gas, which is sent to the condenser. The condenser dissipates heat into the outside air and condenses into a high-pressure liquid, which then flows into the evaporator tube through throttling and pressure reduction of the capillary tube, thereby realizing circulating refrigeration.

[0004] Regarding the above-mentioned related technologies, when the evaporator tube is wrapped around the outside of the cold tank, the contact part of the evaporator tube and the cold tank cools down the water in the cold tank, while the non-contact part of the evaporator tube and the cold tank exchanges heat with the outside air at the same time. In the summer, when the ambient temperature is high, the refrigerant in the evaporator tube will evaporate quickly into refrigerant gas, resulting in poor cooling effect of the evaporator tube. There is still room for improvement. Utility Model Content

[0005] In order to improve the refrigeration effect of the evaporating tube, the present application provides a cold tank assembly and a water dispenser having the assembly.

[0006] In the first aspect, the present application provides a cold tank assembly, which adopts the following technical solution:

[0007] A cold tank assembly comprises a cold tank, an evaporating tube and a refrigerator, wherein the evaporating tube is arranged on the outside of the cold tank, an evaporating tank is provided on the cold tank for installing the evaporating tube, the refrigerator is connected to both ends of the evaporating tube, the refrigerator drives the refrigerant in the evaporating tube to flow and cools the refrigerant; the evaporating tube is provided with a heat insulation cover for isolating the evaporating tube, the heat insulation cover is located outside the evaporating tank, and the cold tank is provided with a fixing device for fixing the heat insulation cover.

[0008] By adopting the above technical solution, when the refrigerator drives the refrigerant in the evaporator tube to cool the water in the cold tank, the heat insulation cover isolates the part of the evaporator tube that is not in contact with the cold tank from the outside world, thereby minimizing the situation in which the refrigerant in the evaporator tube exchanges heat with the outside world through the evaporator tube, resulting in a deterioration in the refrigeration effect of the refrigerant, thereby improving the refrigeration effect of the evaporator tube.

[0009] Optionally, the evaporation tubes are evenly spaced and arranged outside the cold tank.

[0010] By adopting the above technical solution, adjacent evaporator tubes are prevented from contacting each other, thereby preventing heat from being transferred between adjacent evaporator tubes. At the same time, the evenly distributed evaporator tubes cool the cold tank more evenly, thereby improving the refrigeration effect of the evaporator tubes.

[0011] Optionally, a first heat insulation coating for heat insulation is provided at a position between the outer side of the cold tank and the evaporation tube.

[0012] By adopting the above technical solution, a first thermal insulation coating is provided at the interval between the cold tank and the evaporating tube, so as to avoid as much as possible the cold water in the cold tank from exchanging heat with the outside through the cold tank, which causes the temperature of the already refrigerated water to rise, thereby improving the thermal insulation effect of the cold tank.

[0013] Optionally, a thermally conductive coating for heat conduction is provided on one side of the cold tank close to the evaporation tube, the thermally conductive coating is located in the evaporation tank, and the thermally conductive coating is attached to the evaporation tube.

[0014] By adopting the above technical solution, when the evaporator tube cools the water in the cold tank, the thermal conductive coating improves the heat exchange efficiency between the evaporator tube and the water in the cold tank, thereby improving the refrigeration efficiency of the evaporator tube.

[0015] Optionally, a second thermal insulation coating for heat insulation is provided on one side of the thermal insulation cover close to the evaporation tube, and the second thermal insulation coating is in contact with the evaporation tube.

[0016] By adopting the above technical solution, after the heat insulation cover isolates the evaporator tube from the outside world, the second heat insulation coating further prevents the evaporator tube from exchanging heat with the outside world, prevents the heat of the evaporator tube from being lost, and allows more heat of the evaporator tube to be exchanged with the cold tank, thereby improving the refrigeration effect of the evaporator tube.

[0017] Optionally, the fixing device includes a holder, which is arranged on a side of the cold tank close to the heat insulation cover, and the holder is symmetrically arranged along two opposite sides of the evaporation tank, and the holder is attached to and pressed against a side of the heat insulation cover away from the evaporation tube.

[0018] By adopting the above technical solution, when the heat insulation cover isolates the evaporation tube, the holder is attached to and pressed against the heat insulation cover, thereby preventing the heat insulation cover from falling off the evaporation tube, thereby improving the stability of the heat insulation state of the heat insulation cover.

[0019] Optionally, the holders are evenly spaced along the trajectory of the evaporation tank.

[0020] By adopting the above technical solution, the holders are evenly spaced along the trajectory of the evaporation tank, so that when the holders fix the heat insulation cover, the force on the heat insulation cover is even, thereby improving the stability of the heat insulation cover when it is fixed.

[0021] Optionally, a positioning strip is provided on one side of the heat insulation cover close to the card seat, and a positioning groove for inserting the positioning strip is provided on the card seat.

[0022] By adopting the above technical solution, when the heat insulation cover is covered on the outer side of the evaporation tube, the positioning strip is aligned with the positioning groove, so that the heat insulation cover covers the evaporation tube, preventing the heat insulation cover from failing to cover the evaporation tube completely, thereby improving the accuracy of the heat insulation cover when covering.

[0023] Optionally, a clamping head is provided on one side of the heat insulation cover close to the clamping seat, and a clamping slot for clamping the clamping head is provided on the clamping seat, and the clamping head abuts against the clamping seat in the clamping slot.

[0024] By adopting the above technical solution, when the heat insulation cover covers the evaporation tube, the clamping head is clamped in the clamping groove, so that the clamping head and the clamping seat are abutted against each other, preventing the heat insulation cover from being separated from the clamping seat, thereby improving the stability of the connection between the heat insulation cover and the clamping seat.

[0025] In the second aspect, the present application provides a water dispenser, which adopts the following technical solution:

[0026] A water dispenser comprises a shell, wherein the cold tank, the evaporating tube, the heat insulation cover and the refrigerator are all arranged inside the shell.

[0027] By adopting the above technical solution, the cold tank, evaporator tube, heat insulation cover and refrigerator are all arranged inside the shell. On the one hand, the shell protects the cold tank, evaporator tube, heat insulation cover and refrigerator. On the other hand, the shell further isolates the cold tank, evaporator tube and heat insulation cover, thereby improving the refrigeration effect of the evaporator tube.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. When the refrigerator drives the refrigerant in the evaporator tube to cool the water in the cold tank, the heat insulation cover isolates the part of the evaporator tube that is not in contact with the cold tank from the outside world, thereby minimizing the situation where the refrigerant in the evaporator tube exchanges heat with the outside world through the evaporator tube, resulting in a deterioration of the refrigeration effect of the refrigerant, thereby improving the refrigeration effect of the evaporator tube;

[0030] 2. By making adjacent evaporator tubes non-contact with each other, heat is prevented from being transferred between adjacent evaporator tubes. At the same time, the evenly distributed evaporator tubes cool the cold tank more evenly, thereby improving the refrigeration effect of the evaporator tubes;

[0031] 3. After the evaporator tube is isolated from the outside world by the heat insulation cover, the second heat insulation coating further prevents the evaporator tube from exchanging heat with the outside world, prevents the heat loss of the evaporator tube, and allows more heat of the evaporator tube to be exchanged with the cold tank, thereby improving the refrigeration effect of the evaporator tube.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-4 This application is described in further detail.

[0038] Reference Figure 1 and Figure 2 The embodiment of the present application discloses a cold tank assembly and a water dispenser having the assembly, including a shell 6, a cold tank 1, an evaporating tube 2, a refrigerator 3, a heat insulation cover 4 and a fixing device 5. The shell 6 is used for installing the cold tank 1, the evaporating tube 2 and the refrigerator 3. The cold tank 1 is used to hold water, and the cold tank 1 is cylindrical. The water inlet pump, the water inlet pipe and the water outlet pump, the water outlet pipe and other devices connected to the cold tank 1 are not described here. The evaporating tube 2 is spirally wound and fixed on the outside of the cold tank 1. The refrigerator 3 includes a compressor, a condenser and a capillary tube connected in sequence, wherein the compressor is connected to one end of the evaporating tube 2, and the capillary tube is connected to the other end of the evaporating tube 2, so that the refrigerant vapor heated in the evaporating tube 2 is cooled and liquefied and then circulated and cooled again, so that the refrigerator 3 drives the refrigerant to circulate in the evaporating tube 2, so that the evaporating tube 2 cools the water in the cold tank 1. The heat insulation cover 4 is installed on the outside of the evaporation tube 2. The heat insulation cover 4 can be made of glass fiber material. The heat insulation cover 4 covers the evaporation tube 2 on the outside of the cold tank 1, thereby preventing the evaporation tube 2 from exchanging heat with the outside through the part that is not in contact with the cold tank 1. The fixing device 5 is installed on the side of the cold tank 1 close to the evaporation tube 2. The fixing device 5 is used to fix the evaporation tube 2 on the cold tank 1, thereby preventing the evaporation tube 2 from falling off the cold tank 1.

[0039] Reference Figure 3 and Figure 4The cold tank 1 is provided with an evaporation tank 11 for installing the evaporation tube 2. The evaporation tanks 11 are evenly spaced and arranged outside the cold tank 1. After the evaporation tube 2 is installed in the evaporation tank 11, the evaporation tube 2 is evenly spaced and arranged outside the cold tank 1, so that the evaporation tube 2 cools the water in the cold tank 1 more evenly. At least half of the evaporation tube 2 is located outside the evaporation tank 11 in the radial direction, and the part of the evaporation tube 2 covered by the isolation cover is the part of the evaporation tube 2 located outside the evaporation tank 11.

[0040] Reference Figure 3 and Figure 4 A thermal conductive coating 13 is coated on one side of the cold tank 1 close to the evaporation tube 2. The thermal conductive coating 13 can be formed by adhering a nanographene coating or the like in the evaporation tank 11. When the evaporation tube 2 is installed in the evaporation tank 11, the thermal conductive coating 13 is attached to the evaporation tube 2, so that heat exchange between the evaporation tube 2 and the cold tank 1 can be performed quickly.

[0041] Reference Figure 3 and Figure 4 The portion of the outer side of the cold tank 1 that is not in contact with the evaporating tube 2 is coated with a first thermal insulation coating 12. The first thermal insulation coating 12 can be formed by adhering an inorganic thermal insulation coating to the interval between the cold tank 1 and the evaporating tube 2, so that the first thermal insulation coating 12 isolates the portion of the cold tank 1 that should not exchange heat from the outside world, thereby reducing the occurrence of heat exchange between the cold tank 1 and the outside world.

[0042] Reference Figure 3 and Figure 4 A second thermal insulation coating 41 is coated on one side of the thermal insulation cover 4 close to the evaporation tube 2. The second thermal insulation coating 41 can be formed by adhering an inorganic thermal insulation coating to the inner side of the thermal insulation cover 4. When the thermal insulation cover 4 covers the evaporation tube 2, the second thermal insulation coating 41 fits with the portion of the evaporation tube 2 outside the evaporation tank 11, thereby further reducing the occurrence of heat exchange between the evaporation tube 2 and the outside world.

[0043] Reference Figure 3 and Figure 4 The fixing device 5 includes a holder 51, which is fixed to one side of the cold tank 1 close to the heat shield 4. The holders 51 are symmetrically arranged on opposite sides of the evaporation tank 11. When the heat shield 4 covers the evaporation tube 2, the heat shield 4 is squeezed between two symmetrical holders 51, so that the holder 51 fits and presses the heat shield 4 to prevent the heat shield 4 from falling off the evaporation tube 2. Multiple holders 51 are evenly spaced along the trajectory of the evaporation tank 11, so that the holders 51 exert a uniform force on the heat shield 4, ensuring the stability of the heat shield 4 when covering the evaporation tube 2.

[0044] Reference Figure 3 and Figure 4The heat insulation cover 4 is integrally provided with a positioning strip 42 on one side close to the holder 51, and the holder 51 is correspondingly provided with a positioning groove 511 for the positioning strip 42 to be inserted into. When the heat insulation cover 4 is covered on the evaporation tube 2, the positioning strip 42 is aligned with the positioning groove 511, and then the heat insulation cover 4 is squeezed into the holder 51, so that the heat insulation cover 4 of the corresponding length covers the evaporation tube 2 of the corresponding length, preventing the evaporation tube 2 from being not completely covered. After the positioning strip 42 enters the positioning groove 511, the positioning strip 42 and the holder 51 abut against each other along the length direction of the heat insulation cover 4, preventing the heat insulation cover 4 from sliding between the holders 51.

[0045] Reference Figure 3 and Figure 4 A clamping head 43 is integrally provided on one side of the heat insulation cover 4 close to the clamping seat 51, and two clamping heads 43 are symmetrically arranged. The clamping seat 51 is provided with a clamping groove 512 for clamping the clamping head 43. When the heat insulation cover 4 is squeezed into the clamping seat 51, the clamping head 43 is clamped into the clamping groove 512, so that the clamping head 43 is abutted against the clamping seat 51 in the clamping groove 512, preventing the heat insulation cover 4 from detaching from the clamping seat 51, resulting in the inability to effectively isolate the evaporation tube 2.

[0046] The principles of a cold tank assembly and a water dispenser having the assembly according to an embodiment of the present application are as follows:

[0047] After the evaporator tubes 2 are evenly wound and fixed in the evaporator tank 11 of the cold tank 1, the heat insulation cover 4 is squeezed into between the holders 51, so that the second heat insulation coating 41 fits with the heat insulation cover 4, so that the heat insulation cover 4 isolates the portion of the evaporator tube 2 outside the evaporator tank 11 from the outside world, preventing the heat of the evaporator tube 2 from being lost through the portion that is not in contact with the cold tank 1, thereby improving the refrigeration effect of the evaporator tube 2.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
