The liquid feed port 112 can be used for introducing liquid (e.g., water, such as milk, juice, coffee, etc.), and can be specifically liquid with relatively high temperature that is not suitable for direct introduction; the refrigerating device 140 can cool the refrigerant fluid, the second tube 145 serves as a liquid outlet tube and can output the cooled refrigerant fluid, and the first tube 144 serves as a liquid inlet tube and can guide the refrigerant fluid heated after absorbing heat back to the refrigerating chamber 141; the cold-heat exchanger 120 is provided with a first flow passage 121 through which the liquid flowing out from the liquid port 112 passes, and a second flow passage 122 through which the low-temperature refrigerant liquid cooled by the refrigerating device 140 passes, and a heat conducting plate 123 with high heat conductivity is specifically arranged between the first flow passage 121 and the second flow passage 122, so that the liquid and the refrigerant liquid can be separated, and heat transfer can be realized. The outlet of the first flow channel 121 is further connected to a liquid supply port 130, and the cooled liquid flows out through the liquid supply port 130 and can be provided for a user to drink. Specifically, when ice water needs to be drunk, the liquid flowing out of the liquid supply port 112 and the refrigerant liquid are heat-exchanged by the heat exchanger 120, and the liquid is cooled to a temperature required by a user. On one hand, the cooling effect is good, the heat exchange between the liquid in the first flow channel 121 and the refrigerant liquid in the second flow channel 122 is greatly facilitated, and the cooling time is greatly shortened; on the other hand makes refrigeration subassembly 146 can cool off the refrigerating fluid in refrigeration chamber 141 in advance, perhaps when the user needs to drink water, just begins to cool off the refrigerating fluid to when making the liquid that flows out from liquid supply port 112 need cool down, can in time carry out the heat transfer with the refrigerating fluid, still can be in the heat transfer in-process, last to the refrigerating fluid cooling through refrigeration subassembly 146, it is long when further having shortened the cooling. So that a user can obtain a cup of beverage with proper temperature in a short time, and the cup of beverage is convenient for the user to use.

It is understood that the refrigerant fluid may be water or a solution with a low freezing point, which is well-known in the art and is not specifically disclosed herein. Further, the freezing temperature of the refrigerant fluid is lower than 0 ℃, which can ensure that the refrigerant fluid is still not frozen after being frozen, so that the refrigerant fluid can be extracted into the cold-heat exchanger 120 for utilization, and the high-temperature liquid can be rapidly cooled. Particularly, the high-temperature liquid can be cooled to different temperatures by controlling the extraction flow rate of the refrigerating liquid, so that various drinking requirements are met.

Further, the heating element 113 may be a heating tube 114 as shown in fig. 5, a coil plate, an electric heating film, or the like.

Further, the first and second tubes 144, 145 both project into the refrigeration cavity 141, ensuring that the refrigerant fluid can reliably flow into and out of the refrigeration cavity 141. With the bottom wall of the refrigeration cavity 141 as a reference, the distance between the tube body and the bottom wall can reflect the length of the tube body extending into the refrigeration cavity 141, and the distance is specifically the distance between the tube opening at the end of the tube body extending into the refrigeration cavity 141 and the bottom wall of the refrigeration cavity 141. The distance between the second tubular body 145 and the bottom wall of the refrigeration cavity 141 is smaller than the distance between the first tubular body 144 and the bottom wall of the refrigeration cavity 141, that is, as shown in fig. 11, the length L2 of the second tubular body 145 extending into the refrigeration cavity 141 is greater than the length L1 of the first tubular body 144 extending into the refrigeration cavity 141. Because the existing refrigerant fluid in the refrigeration cavity 141 is cooled by the refrigeration assembly 146 and is in a low temperature state, and the temperature of the refrigerant fluid flowing back to the refrigeration cavity 141 through the first tube body 144 is relatively high, the tube orifice of the first tube body 144 is farther away from the bottom wall of the refrigeration cavity 141 than the tube orifice of the second tube body 145, so that the backflow refrigerant fluid can be prevented from rapidly reaching the vicinity of the tube orifice of the second tube body 145, and therefore, the colder part of the refrigerant fluid in the refrigeration cavity 141 is pumped out first, and the refrigeration efficiency of the refrigeration device 140 and the cooling efficiency when the refrigerant fluid is used for cooling the high-temperature liquid are ensured.

Specifically, the orifice of the second tube 145 may be made to extend into the bottom of the refrigeration cavity 141 and close to the bottom wall of the refrigeration cavity 141, the second tube 145 being immersed in the refrigerant fluid, while the orifice of the first tube 144 is made to be close to the top wall of the refrigeration cavity 141, the first tube 144 not extending into the refrigerant fluid.

Specifically, the refrigerant fluid is extracted through the second tube 145 to the maximum amount (i.e., the maximum flow rate), so that the cooling efficiency when the high-temperature refrigerant fluid is used to cool the high-temperature refrigerant fluid can be ensured, the influence of the returned high-temperature refrigerant fluid on the low-temperature refrigerant fluid in the refrigeration cavity 141 can be further reduced, and the cooling efficiency can be ensured.

Further, the distance D between the second tube 145 and the bottom wall of the refrigeration cavity 141 ranges from 1mm to 50 mm. The smaller the distance D between the second tube 145 and the bottom wall of the refrigeration cavity 141, the more the effect of the returned relatively high-temperature refrigerant liquid on the original relatively low-temperature refrigerant liquid can be reduced, and the refrigeration efficiency of the refrigeration device 140 and the cooling efficiency when the high-temperature refrigerant liquid is cooled by the refrigerant liquid can be ensured; on the other hand, the higher the hydraulic pressure of the orifice fitting of the second tube 145, the more advantageous the extraction of the refrigerant fluid. The lower limit of the value range ensures that a gap exists between the second pipe 145 and the refrigeration cavity 141, and the second pipe 145 can be prevented from being blocked, so that the second pipe 145 can smoothly discharge liquid, the refrigeration liquid can be reliably output to the heat exchanger 120, and the reliability of the liquid supply device 100 is ensured. The upper limit of the value range ensures that the second pipe 145 can be immersed in the refrigerant fluid under the condition that the refrigerant fluid is filled in the refrigerant cavity 141, thereby ensuring that the second pipe 145 smoothly discharges the refrigerant fluid. For example, the distance D between the second tube 145 and the bottom wall of the refrigeration cavity 141 may be 2mm, 5mm, 10mm, 15mm, 20mm, 30mm, 40mm, so as to adapt to refrigeration cavities 141 with different sizes, and meet different design requirements.

Further, the liquid supply device further includes: the heat generating assembly 110, the heat generating assembly 110 includes a liquid inlet 111, a liquid outlet and a heat generating element 113, the liquid inlet 111 is used for connecting a liquid source (such as a liquid storage tank 150), the heat generating element 113 is used for heating the liquid flowing through the liquid inlet 111, the liquid outlet is configured as a liquid feeding port 112 as shown in fig. 6, or the liquid outlet is communicated with the liquid feeding port 112. The heating element 110 can heat the liquid flowing from the liquid source, and particularly can heat the liquid to boiling, so as to ensure the hygienic and safe drinking. After the normal temperature liquid is heated to boiling by the heating component 110, the normal temperature liquid can exchange heat with the refrigerant liquid through the heat exchanger 120, and the boiling water is rapidly cooled to the temperature required by the user, so that the user can obtain a cup of boiled ice water which is just boiled and is immediately cooled to the proper temperature in a short time (about 1 minute, even within 1 minute), and the use of the user is convenient. In addition, because liquid can in time exchange heat with the refrigerant liquid after being heated, and flow out and supply liquid mouth 130, can effectively avoid boiling water long-time storage to breed the bacterium again, further guarantee to drink the security. The liquid outlet may be specifically configured as a liquid feeding port 112, i.e., a liquid outlet connected with the inlet of the first flow channel 121 to provide heated liquid; the liquid outlet can also be communicated with the liquid feeding port 112, that is, the heating component 110 is communicated with the first flow channel 121 through the liquid feeding port 112, so that the structural components can be connected to work together, and the structural components have respective independence, thereby facilitating subsequent disassembly and maintenance.

The above-mentioned several kinds of design can select one to choose for use, also can make up, this all is the utility model discloses a realization.

In addition, the refrigeration cup 142 and the refrigeration cover 143 can be detachably connected, so that the refrigeration cup can be conveniently detached during subsequent maintenance, and the service life of the product can be prolonged.

In addition, as shown in fig. 18 to 20, when a part of the structure in the refrigeration assembly 146 is independently arranged outside the refrigeration cup 142, if the structure allows, a second thermal insulation member 148 (such as thermal insulation cotton and the like) can be integrally covered outside the refrigeration cup 142 and the part of the structure, so as to enhance the thermal insulation effect; as shown in fig. 11 and 15, when the structure is not allowed, but only a partial area of the refrigeration cup 142 is in contact with the refrigeration component 146, a second heat preservation member 148 (such as heat insulation cotton, foaming material and the like) which avoids the refrigeration component 146 may be arranged inside the casing 149 and outside the refrigeration cup 142, and at this time, the refrigeration cup 142 as a whole may be made of the same material (all made of heat conduction material) instead of different materials according to whether the refrigeration cup is in contact with the refrigeration component 146, which may facilitate processing and ensure heat preservation effect.
