Referring to fig. 3 and 4, in some embodiments of the present invention, an outward protruding bypass box 122 is disposed on a sidewall of the second compartment 120, a cannula is used to connect to a port of the second compartment 120 on the bypass box 122, and the bypass box 122 may be a plastic box or a metal box and is used to make a way for the port of the cannula when foaming, so as to prevent the port of the cannula from being damaged.
Referring to fig. 8 and 9, in some embodiments of the present invention, a hot end assembly 200 of a rapid cooling device includes: an upper housing half 210 having an upper interior cavity; a lower housing half 220 having a lower interior cavity; an upper cooling assembly connected to the upper half-shell 210 and located in the upper inner cavity, wherein an upper cavity 230 for accommodating a cold storage liquid is disposed inside the upper cooling assembly; a lower cooling assembly connected to the lower half shell 220 and located in the lower inner cavity, and a lower cavity 240 for accommodating a cold storage liquid is provided therein; wherein the upper cooling assembly and the lower cooling assembly can enclose a cylindrical chamber for containing the beverage.
The principle that the hot end assembly 200 can accelerate the rapid cooling of the beverage is that the cold accumulation liquid which is subjected to heat exchange and temperature reduction by the cold end assembly 300 flows through the upper cavity 230 and the lower cavity 240 of the hot end assembly 200 through the cold accumulation liquid pipeline, the beverage is placed in the cylindrical cavity to be fully contacted with the upper cooling assembly and the lower cooling assembly, and heat on the beverage is rapidly transferred to the cold accumulation liquid in a contact heat exchange mode, so that the rapid cooling of the beverage is realized. Since the hot end assembly 200 is disposed in the first compartment 110, the first compartment 110 may be a refrigerating compartment or a temperature-changing compartment, and the temperature of the first compartment 110 is much higher than that of the cold storage liquid, the risk of freezing and bursting of the beverage placed in the hot end assembly 200 can be avoided by controlling the time of the circulation flow of the cold storage liquid and stopping the flow of the cold storage liquid from the cold end assembly 300 to the hot end assembly 200 after a certain time.

Referring to fig. 1 and 9, in some embodiments of the present invention, the refrigerator is provided with a shelf 111 in the first compartment 110, and the hot end assembly 200 may be disposed on the shelf 111, and in order to ensure that condensed water may naturally flow down from the outer surface of the upper half case 210 or the lower half case 220, the outer surface of the upper half case 210 and/or the lower half case 220 is disposed to be inclined from the horizontal plane.
In a specific embodiment, the outer surface of the lower half-shell 220 is flush with the shelf 111, and the outer surface of the upper half-shell 210 is disposed at an inclination of 7 ° to the horizontal plane, and condensed water generated on the outer surface of the upper half-shell 210 may naturally flow down.
It will be appreciated that keeping the outer surface of the lower half 220 and the outer surface of the upper half 210 inclined to each other maintains the upper half 210 at an inclination to the horizontal when the hot end assembly 200 is placed on the shelf 111, thereby ensuring natural downflow of the condensate on the hot end assembly 200.
Referring to fig. 8 and 9, in some embodiments of the present invention, the upper cooling assembly further includes an upper cold storage housing 231 and an upper cooling plate, the lower cooling assembly further includes a lower cold storage housing 241 and a lower cooling plate 242, the upper cavity 230 is enclosed by the upper cold storage housing 231 and the upper cooling plate, and the lower cavity 240 is enclosed by the lower cold storage housing 241 and the lower cooling plate 242. The upper cavity 230 is communicated with the lower cavity 240, wherein the lower cold accumulation housing 241 is provided with a lower liquid inlet 243 and a lower liquid outlet 244, the upper cold accumulation housing 231 is provided with an upper liquid inlet 233 and an upper liquid outlet 234, wherein the upper liquid inlet and the lower liquid outlet are sequentially arranged from low to high in the vertical direction: lower liquid inlet 243, lower liquid outlet 244, upper liquid inlet 233 and upper liquid outlet 234. The cold accumulation liquid pipeline comprises a liquid inlet pipe 261, a liquid outlet pipe 263 and a connecting pipe 262, and correspondingly, the sleeve comprises a liquid return sleeve 420 and a liquid outlet sleeve 410. The cartridge 310 includes an inlet 311 and an outlet 312, the inlet 311 of the cartridge 310 being located above the outlet 312. Wherein, the liquid inlet pipe 261 passes through the liquid outlet sleeve 410, one end is connected with the outlet 312 of the liquid storage box 310, and the other end is connected with the lower liquid inlet hole 243 of the lower cavity 240; the liquid outlet pipe 263 penetrates through the liquid return sleeve 420, one end of the liquid outlet pipe 263 is connected with the upper liquid outlet hole 234 of the upper cavity 230, and the other end of the liquid outlet pipe 263 is connected with the inlet 311 of the liquid storage box 310; one end of the connection pipe 262 is connected to the lower outlet hole 244 of the lower chamber 240, and the other end is connected to the upper inlet hole 233 of the upper chamber 230.
When the rapid cooling device needs to start the rapid cooling function, the beverage is put into the cylindrical chamber enclosed by the upper cooling component and the lower cooling component, the pump (not shown in the figure) drives the low-temperature cold accumulation liquid in the liquid storage box 310 to flow into the hot end component 200, and the low-temperature cold accumulation liquid provides a large amount of cold for the beverage at the hot end component 200 to accelerate the cooling of the beverage. After a period of time, the beverage has cooled to a preset temperature, the pump stops running, the cold accumulation liquid stops circulating, and the warm end assembly 200 is disposed in the refrigerating compartment, avoiding the risk of freezing and bursting of the beverage.
When the pump is started, the direction of the flow of the cold storage liquid is as follows: the cold-storage liquid flows into the liquid inlet pipe 261 from the liquid storage box 310 through the outlet 312, flows into the lower cavity 240 from the liquid inlet pipe 261 through the lower liquid inlet 243, flows into the connecting pipe 262 from the lower cavity 240 through the lower liquid outlet 244, flows into the upper cavity 230 from the connecting pipe 262 through the upper liquid inlet 233, flows into the liquid outlet pipe 263 from the upper cavity 230 through the upper liquid outlet 234, and flows back into the liquid storage box 310 from the liquid outlet pipe 263 through the inlet 311. In order to improve the heat transfer efficiency of the beverage cooling process, the hot end assembly 200 is obliquely arranged, so that the cold accumulation liquid flows in from a low position and flows out from a high position, the cold accumulation liquid is ensured to be filled in the lower cavity 240 and the upper cavity 230, and the heat exchange between the cold accumulation liquid and the beverage is facilitated. Meanwhile, because the inlet 311 is positioned above the outlet 312, the cold accumulation liquid goes in and out of the liquid storage box 310, and the cold accumulation liquid flowing back to the upper part of the liquid storage box 310 extrudes the cold accumulation liquid positioned below the liquid storage box 310 from the outlet 312 due to gravity, so that the phenomenon that the cold accumulation liquid does not flow in certain positions of the liquid storage box 310 is avoided.
After the pump stops operating, since the liquid storage box 310 is located below the upper and lower cavities 230 and 240, the cold storage liquid in the upper and lower cavities 230 and 240 may automatically flow back into the liquid storage box 310 due to gravity.
In some embodiments, PE tubes are used for both feed 261 and drain 263. It is understood that, since the PE pipe has excellent low temperature resistance, in the above embodiments, based on the consideration of low temperature resistance, although the conveying pipe is made of PE material, the material of the conveying pipe is not limited to PE, but may also include PPE or PP. The hose can be made of other materials, can penetrate through the sleeve pipe and can meet the temperature performance for conveying the cold storage liquid as long as the hose has certain elasticity, and can serve as a cold storage liquid pipeline. And the outer diameter of the cold accumulation liquid pipeline is smaller than the inner diameter of the sleeve, so that the cold accumulation liquid pipeline can conveniently penetrate through the sleeve.
In some specific embodiments, an upper insulating layer (not shown) is disposed between the inner surface of the upper half-shell 210 and the upper cooling assembly, the upper insulating layer is disposed between the inner surface of the upper half-shell 210 and the upper cold storage shell 231, a lower insulating layer (not shown) is disposed between the inner surface of the lower half-shell 220 and the lower cooling assembly, and the lower insulating layer is disposed between the inner surface of the lower half-shell 220 and the lower cold storage shell 241.
