Description

Technical Field

[0001] The utility model belongs to the technical field of tea drinking machines, in particular to an energy-saving and environment-friendly refrigeration system of a tea drinking machine. Background Art

[0002] The existing refrigeration method of tea drinking machines is to pass hot tea through a refrigerated aluminum ingot, which directly cools the hot tea. The aluminum ingot relies on the refrigeration system to maintain a low temperature. Since the hot tea is placed in the aluminum ingot, the contact area between the hot tea and the aluminum ingot is limited, which will cause the hot tea to cool down very slowly. In order to improve the refrigeration effect, the flow rate of the refrigerant flowing through the aluminum ingot is generally increased to ensure that the aluminum ingot maintains a low temperature, or the volume of the aluminum ingot is increased to ensure that the hot tea can fully contact the aluminum ingot.

[0003] However, these two solutions have some problems: increasing the flow rate of the refrigerant will increase the energy consumption of the refrigeration system, while increasing the volume of the aluminum ingot will make the refrigeration system too large, making it inconvenient to transport and use. Utility Model Content

[0004] In view of this, the present invention provides an energy-saving and environmentally friendly refrigeration system for a tea machine to solve the above problems.

[0005] An energy-saving and environmentally friendly refrigeration system for a tea dispenser includes a refrigeration tube assembly and a compressor assembly connected to the refrigeration tube assembly. The refrigeration tube assembly and the compressor assembly are covered by a housing. The refrigeration tube assembly includes a U-shaped tube, a cooling tube that fits over the U-shaped tube, and an aluminum ingot that fits over the U-shaped tube and the cooling tube. A hot tea tube and an iced tea tube are connected to each end of the U-shaped tube, respectively. The cooling tube fits over the U-shaped tube at one end connected to the hot tea tube, so that the hot tea in the U-shaped tube contacts the cooling tube and the aluminum ingot in sequence.

[0006] Furthermore, a tea dispensing assembly is provided on one side of the shell.

[0007] Furthermore, the tea dispensing component includes a tea dispensing bin, a tea outlet arranged at the bottom of the tea dispensing bin, a metering pump arranged in the tea dispensing bin, and a control panel arranged on the front of the tea dispensing bin, the ice tea pipe is connected to the metering pump, and the metering pump is connected to the tea outlet.

[0008] Furthermore, the tea outlet bin is communicated with the shell, and a hot tea tube installation opening is provided at the bottom of the tea outlet bin for facilitating the passage of the hot tea tube.

[0009] Furthermore, the compressor assembly includes a compressor body and a spiral heat dissipation tube connected to the compressor body, one end of the spiral heat dissipation tube is connected to the cooling tube, and the other end of the cooling tube is connected to the compressor body.

[0010] Furthermore, a positioning cylinder is provided inside the tea outlet bin, the aluminum ingot is inserted into the positioning cylinder, and the positioning cylinder is spaced apart from the compressor assembly.

[0011] Compared with the prior art, the energy-saving and environmentally friendly refrigeration system of the tea drinking machine provided by the present invention is capable of preliminarily cooling the hot tea by arranging a U-shaped tube and sheathing a cooling tube on the outside of the U-shaped tube. An aluminum ingot is sheathed on the outside of the cooling tube, which is in direct contact with the cooling tube and will further cool the tea, thereby achieving secondary cooling. Since the refrigerant in the cooling tube directly flows out after heating, it does not affect the refrigerant temperature in the aluminum ingot. Therefore, the aluminum ingot absorbs less heat and can maintain a lower temperature, which makes the second cooling faster and improves the cooling speed. At the same time, the temperature can be lowered, which improves the cooling effect. Since there is no need to increase the cooling speed and effect by increasing the refrigerant flow rate, the cooling energy consumption of the compressor assembly can be effectively reduced. Moreover, since the cooling tube is directly sheathed on the outside of the U-shaped tube, the volume occupied is relatively small, and the volume of the aluminum ingot will not be significantly increased, which is convenient for transportation and use.

[0015] The following is a further detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0016] like Figures 1 to 3As shown in FIG, which is a schematic diagram of the structure of the energy-saving and environmentally friendly refrigeration system of the tea drinking machine provided by the present invention. The energy-saving and environmentally friendly refrigeration system of the tea drinking machine includes a refrigeration pipe group 20, a compressor assembly 30 spaced apart from the refrigeration pipe group 20, and a tea dispensing assembly 10 connected to the refrigeration pipe group 20. The energy-saving and environmentally friendly refrigeration system of the tea drinking machine also includes other functional modules, such as a control assembly and a power supply assembly for controlling the start and stop of the compressor assembly 30, etc. These should be technologies well known to those skilled in the art and will not be described in detail here.

[0017] The tea dispensing component 10 includes a tea dispensing bin 11, a metering pump 12 arranged in the tea dispensing bin 11, a tea outlet 13 inserted at the bottom of the tea dispensing bin 11, and a control panel 14 arranged on the outer wall of the tea dispensing bin 11. The tea dispensing bin 11 is a rectangular shell for containing part of the metering pump 12. One end of the hot tea pipe 22 described below passes through the bottom of the tea dispensing bin 11 and is connected to the external tea barrel. The water outlet end of the metering pump 12 is connected to the tea outlet 13 through a pipeline, and the water inlet end of the metering pump 12 is connected to the ice tea pipe 23. The metering pump 12 draws the iced tea from the ice tea pipe 23 and sends it into the tea outlet 13 to produce iced tea. The control panel 14 is used to cooperate with the controller to control the opening and closing of the metering pump 12 and control the outflow of tea.

[0018] The refrigeration tube assembly 20 includes a U-shaped tube 21, a hot tea tube 22 connected to the water inlet end of the U-shaped tube 21, an ice tea tube 23 connected to the water outlet end of the U-shaped tube 21, a cooling tube 24 sleeved on the outside of the U-shaped tube 21, and an aluminum ingot 25 sleeved on the outside of the U-shaped tube 21 and the cooling tube 24. The refrigeration tube assembly 20 and the compressor assembly 30 are covered with a shell 40. The shell 40 not only protects the refrigeration tube assembly 20 and the compressor assembly 30, but also facilitates the fixing and connection of the various components.

[0019] The U-shaped tube 21 is used to hold hot tea and cool it. The hot tea enters the U-shaped tube 21 through the hot tea tube 22 and flows out through the ice tea tube 23. The length of the U-shaped tube 21 is long enough. When the hot tea flows in, the heat of the tea will continue to diffuse to the U-shaped tube 21, thereby achieving cooling. The material of the U-shaped tube 21 can be a metal material such as stainless steel, which has good thermal conductivity and can conduct the heat of the hot tea to the outside through the U-shaped tube 21. It should be noted that in this embodiment, the U-shaped tube 21 has only one bending portion. In actual use, multiple bends can be set, so that the U-shaped tube 21 is S-shaped, which can increase the contact area between the hot tea in the U-shaped tube 21 and the cold source, thereby improving the cooling effect.

[0020] The hot tea pipe 22 and the ice tea pipe 23 are transparent rubber hoses, respectively, so that the accumulation of tea scale in the hot tea pipe 22 and the ice tea pipe 23 can be easily determined by observation, and the pipes can be replaced in time.

[0021] The cooling tube 24 is sleeved on the outside of the U-shaped tube 21 and is tightly attached to the U-shaped tube 21. The tube wall of the cooling tube 24 is made of metal such as stainless steel and has good thermal conductivity. The cooling tube 24 is filled with refrigerant. When hot tea flows into the U-shaped tube 21, the heat of the hot tea will diffuse from the tube wall of the U-shaped tube 21 to the tube wall of the cooling tube 24 and will eventually be absorbed by the refrigerant. The two ends of the cooling tube 24 are connected to the compressor assembly 30. The heated refrigerant flows through the compressor assembly 30 and cools down. The cooled refrigerant flows through the U-shaped tube 21 and absorbs heat and heats up, forming a circulating flow of refrigerant. The cooling tube 24 is sleeved on one end of the U-shaped tube 21 connected to the hot tea tube 22, and can cool the hot tea immediately when it enters the U-shaped tube 21. The cooling sleeve 24 is not provided at the other end of the U-shaped tube 21, so that the cooled tea in the U-shaped tube 21 directly contacts the aluminum ingot 25 and is further cooled. Since the aluminum ingot 25 itself is not heated in advance by the hot tea in the U-shaped tube 21 , its temperature is lower than the temperature of the refrigerant in the cooling tube 24 , thereby improving the cooling effect.

[0022] The aluminum ingot 25 is a cubic shell. The compressor assembly 30 cools the aluminum ingot 25 to maintain a low temperature. Specifically, the cooling structure includes a hollow casing 251 disposed outside the aluminum ingot 25. This casing 251 is also made of metal, such as stainless steel or copper, and is filled with refrigerant. This refrigerant circulates through the compressor assembly 30, maintaining a low temperature, which in turn keeps the aluminum ingot 25 cool. In actual use, the hollow casing 251 can be replaced with a coiled copper tube to stabilize the refrigerant flow direction and provide more uniform cooling.

[0023] The compressor assembly 30 includes a compressor body 31 and a spiral heat dissipation tube 32 connected to the compressor body. After being heated by the tea, the refrigerant first enters the spiral heat dissipation tube 32 for initial heat dissipation, and then cools down by flowing through the compressor body 31. It should be noted that the refrigeration principle and refrigeration structure of the compressor assembly 30 are conventional, and the connection method between the spiral heat dissipation tube 32 and the compressor assembly 30 is also conventional and well known to those skilled in the art, and will not be further described here.

[0024] During use, hot tea flows from outside into the U-shaped tube 21 through the hot tea pipe 22. It should be noted that the hot tea pipe 22 is equipped with a water pump to extract the hot tea from outside. The hot tea entering the U-shaped tube 21 first comes into contact with the cooling tube 24, where it is initially cooled to approximately 35-45 degrees Celsius. It then comes into contact with the aluminum ingot 25, where it is further cooled to 4-6 degrees Celsius.

[0025] Compared with the prior art, the energy-saving and environmentally friendly refrigeration system of the tea drinking machine provided by the present invention is capable of preliminarily cooling the hot tea by setting a U-shaped tube 21 and sleeve a cooling tube 24 on the outside of the U-shaped tube 21. An aluminum ingot 25 is sleeved on the outside of the cooling tube 24. The aluminum ingot 25 is in direct contact with the cooling tube 24 and will further cool the tea, thereby achieving secondary cooling. Since the refrigerant in the cooling tube 24 flows out directly after heating, it does not affect the refrigerant temperature in the aluminum ingot 25. Therefore, the aluminum ingot 25 absorbs less heat and can maintain a lower temperature, which makes the second cooling faster and improves the cooling speed. At the same time, the temperature can be lowered, which improves the cooling effect. Since there is no need to increase the cooling speed and effect by increasing the refrigerant flow rate, the cooling energy consumption of the compressor assembly 30 can be effectively reduced. Moreover, since the cooling tube 24 is directly sleeved on the outside of the U-shaped tube 21, the volume occupied is small, and the volume of the aluminum ingot 25 will not be significantly increased, which is convenient for transportation and use.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are included in the scope of the claims of the present invention.
