Description

Technical Field

[0001] The utility model relates to the field of liquid discharging equipment, in particular to a liquid discharging machine capable of realizing liquid discharging in multiple temperature zones. Background Art

[0002] In recent years, in the catering industries such as milk tea, coffee, and bars, a liquid discharging machine has emerged. Multiple different liquid storage bins are arranged in this liquid discharging machine, and each liquid storage bin contains a different liquid beverage. During use, according to requirements, different pumps are used to pump these beverages to the liquid discharging head and flow into the cup below the liquid discharging head.

[0003] In the hot summer, consumers often need to drink low-temperature beverages. The traditional method is to directly add ice cubes to the beverages or use ice cubes inside the liquid discharging machine to quickly cool hot tea soup and other beverages. No matter which of the above methods is used, a certain amount of ice cubes is required. Therefore, many stores need to configure larger ice makers to prepare ice cubes. Firstly, the cost is increased, and secondly, it will also occupy a certain amount of store space. At the same time, the process of putting ice cubes is labor-consuming, reducing the operation efficiency of the store.

[0004] Since the choice of beverages is greatly affected by temperature, the ice consumption in the store usually increases sharply under hot weather conditions. Therefore, there is often a shortage of ice cubes. To solve this problem, only multiple ice makers need to be added or a larger ice maker needs to be configured, which has certain problems both in terms of cost and occupied space. And after summer, the redundant ice makers can only be idle.

[0005] Therefore, there is a need for a method or device that can solve the above problems now. Summary of the Invention

[0006] The utility model is proposed to solve the above-mentioned deficiencies existing in the prior art, and provides a liquid discharging machine with a simple structure, ingenious design, reasonable layout, which can further cool the beverages pumped out from some liquid storage bins at low temperature to realize liquid discharging in multiple temperature zones.

[0007] The technical solution of the present utility model is: a liquid discharging machine capable of realizing liquid discharging in multiple temperature zones, including a liquid discharging machine body, characterized in that: a compressor 1 is arranged inside the liquid discharging machine body, an outlet pipeline 2 of the compressor 1 is connected to a heat exchanger inlet pipeline 4 on a plate heat exchanger 3 and a connecting branch 5, a first solenoid valve 6 and a second solenoid valve 7 are respectively arranged on the heat exchanger inlet pipeline 4 and the connecting branch 5, the end of the connecting branch 5 is connected to a condenser inlet pipeline 9 on a condenser 8, the plate heat exchanger 3 is arranged on a fructose bin 10, and a temperature sensor 11 is also arranged inside the fructose bin 10, the fructose bin 10 is connected to a liquid discharging head 13 through a fructose pipeline 12, and a discharging pump 14 is also arranged on the fructose pipeline 12, and a heat exchanger outlet pipeline 15 on the plate heat exchanger 3 is connected to the condenser inlet pipeline 9;

[0008] A dryer 17 is arranged on a condenser outlet pipeline 16 of the condenser 8, and the condenser outlet pipeline 16 is connected to one passage of a three-way reversing valve 18, and the other two passages of the three-way reversing valve 18 are respectively communicated with an evaporator inlet pipeline 20 of an evaporator 19 and a cooling inlet pipeline 22 of a cooling heat exchanger 21, and an evaporator outlet pipeline 23 of the evaporator 19 is communicated with a compressor inlet pipeline 24 of the compressor 1;

[0009] The condenser 8 is equipped with a condensing fan 25, and the evaporator 19 is equipped with an evaporating fan 26;

[0010] The inner cavity of the liquid discharging machine body is divided into two parts: a low-temperature cavity and a normal-temperature cavity, and a plurality of liquid bins 27 are respectively placed in the low-temperature cavity and the normal-temperature cavity. When the evaporator 19 works, the cold generated is input into the low-temperature cavity under the action of the evaporating fan 26;

[0011] All the liquid bins 27 are respectively connected to the liquid discharging head 13 through their respective discharging pipelines 28, and a discharging pump 14 is also arranged on the discharging pipeline 28;

[0012] At the same time, all the discharging pipelines 28 connected to the liquid bins 27 located in the low-temperature cavity pass through the cooling heat exchanger 21.

[0013] Compared with the prior art, the present utility model has the following advantages:

[0014] The liquid discharging machine capable of discharging liquid in multiple temperature zones with this structural form has a simple structure, ingenious design and reasonable layout. Aiming at the problems of certain limitations existing in the traditional liquid discharging machine, a special structure is designed. A cooling heat exchanger is added inside the liquid discharging machine, and this cooling heat exchanger can directly utilize the cold generated when the refrigeration system of the liquid discharging machine itself works. The discharging pipelines of a part of the bins in the liquid discharging machine pass through the above-mentioned cooling heat exchanger, that is to say, the drink will absorb the cold in the cooling heat exchanger during the discharging process, so as to achieve the purpose of quickly cooling the drink. It enables the traditional liquid discharging machine to have an additional function of rapid cooling inside the machine, and uses a set of refrigeration system to realize two functions of conventional refrigeration in the low-temperature chamber and rapid cooling of the drink. Therefore, the amount of ice cubes used can be saved, thereby reducing the overall cost of the drink shop, increasing the rate of return, saving the occupied space of the ice maker, and being more conducive to energy conservation and environmental protection;

[0015] And it introduces the heat generated during the operation of the unit into the plate heat exchanger through pipelines, and uses the plate heat exchanger to heat and keep warm the fructose, replacing the traditional electric heating method, that is, making use of the waste heat generated during the operation of the unit and being able to reduce energy consumption.

[0016] At the same time, its manufacturing process is simple and the manufacturing cost is low. Therefore, it can be said that it has multiple advantages, is particularly suitable for popularization and application in this field, and its market prospect is very broad.

[0018] The following will describe the detailed embodiment of the present utility model in conjunction with the drawings. As Figure 1 shown: A liquid discharging machine capable of discharging liquid in multiple temperature zones includes a liquid discharging machine body. A compressor 1 is arranged inside the liquid discharging machine body. The outlet pipeline 2 of the compressor 1 is connected to the heat exchanger inlet pipeline 4 on the plate heat exchanger 3 and a connecting branch 5. A first solenoid valve 6 and a second solenoid valve 7 are respectively arranged on the heat exchanger inlet pipeline 4 and the connecting branch 5. The end of the connecting branch 5 is connected to the condenser inlet pipeline 9 on the condenser 8. The plate heat exchanger 3 is arranged on the fructose bin 10, and a temperature sensor 11 is also arranged inside the fructose bin 10. The fructose bin 10 is connected to the liquid discharging head 13 through a fructose pipeline 12, and a discharging pump 14 is also arranged on the fructose pipeline 12. The heat exchanger outlet pipeline 15 on the plate heat exchanger 3 is then connected to the condenser inlet pipeline 9;

[0019] A dryer 17 is provided on the condenser outlet pipeline 16 of the condenser 8, and the condenser outlet pipeline 16 is connected to one passage of a three-way reversing valve 18. The other two passages of the three-way reversing valve 18 are respectively connected and communicated with the evaporator inlet pipeline 20 of the evaporator 19 and the cooling inlet pipeline 22 of the cooling heat exchanger 21. The evaporator outlet pipeline 23 of the evaporator 19 is then connected and communicated with the compressor inlet pipeline 24 of the compressor 1;

[0020] The condenser 8 is equipped with a condensing fan 25, and the evaporator 19 is equipped with an evaporating fan 26;

[0021] The inner cavity of the liquid discharging machine body is divided into two parts: a low-temperature cavity and a normal-temperature cavity. A plurality of liquid storage bins 27 are respectively placed in the low-temperature cavity and the normal-temperature cavity. The cold generated during the operation of the evaporator 19 is input into the low-temperature cavity under the action of the evaporating fan 26;

[0022] All the liquid storage bins 27 are respectively connected to the liquid discharging head 13 through their respective discharging pipelines 28, and a discharging pump 14 is also provided on the discharging pipeline 28;

[0023] Meanwhile, all the discharging pipelines 28 connected to the liquid storage bins 27 located in the low-temperature cavity pass through the cooling heat exchanger 21.

[0024] The working process of the liquid discharging machine capable of realizing multi-temperature zone liquid discharging according to the embodiment of the present invention is as follows: In the normal working state, the refrigeration system formed by the compressor 1, the condenser 8, the evaporator 19 and the pipelines connecting them works, and the generated cold is input into the low-temperature cavity under the action of the evaporating fan 26 to cool each liquid storage bin 27 placed in the low-temperature cavity;

[0025] When a consumer needs to drink a normal-temperature beverage, the control system controls the discharging pump 14 corresponding to the liquid storage bin 27 placed in the normal-temperature cavity to work, pumps the beverage in the target liquid storage bin 27 to the liquid discharging head 13, and at the same time controls the discharging pump 14 on the fructose pipeline 12 to work, pumps the syrup in the fructose storage bin 10 to the liquid discharging head 13. By controlling the working duration of the two different discharging pumps 14, the sugar content in the finally obtained beverage can be controlled. The mixture of the beverage and the syrup flows into the cup below the liquid discharging head 13 together to obtain the required normal-temperature beverage;

[0026] When a consumer needs to drink a cold beverage, the control system controls the discharge pump 14 corresponding to the liquid storage bin 27 placed in the cold chamber to work, pumps the beverage in the target liquid storage bin 27 to the liquid outlet head 13, and at the same time controls the discharge pump 14 on the fructose pipeline 12 to work, pumps the syrup in the fructose storage bin 10 to the liquid outlet head 13. By controlling the working duration of the two different discharge pumps 14, the sugar content in the finally obtained beverage can be controlled. The mixture of the beverage and the syrup flows into the cup below the liquid outlet head 13 together to obtain the required cold beverage;

[0027] When a consumer needs to drink a cold beverage with a temperature lower than that of the cold chamber, such as a smoothie / snow top beverage or an "ultra-cold" beverage; or during peak hours when the order volume suddenly increases and the pre-stored cold drinks in the refrigerator (such as tea bases, milk pastes, and fruit juices) are about to run out. A signal can be sent to the three-way directional valve 18 through the control system to make the condenser outlet pipeline 16 communicate with the cooling inlet pipeline 22. The low-temperature medium enters the cooling heat exchanger 21, and the low-temperature medium exchanges heat with the beverage flowing through the cooling heat exchanger 21, and the temperature of the beverage is further reduced to quickly obtain a cold beverage;

[0028] During the operation of the liquid outlet machine, in order to keep the syrup in the fructose storage bin 10 in good fluidity all the time, the fructose storage bin 10 needs to be in a relatively high-temperature environment all the time, that is, the temperature sensor 11 located in the fructose storage bin 10 will always detect its temperature. If the temperature is lower than the preset trigger value, the control system will automatically control the first solenoid valve 6 to open and the second solenoid valve 7 to close. At this time, the plate heat exchanger 3 and the condenser 8 are in series. The high-temperature and high-pressure gas discharged from the compressor 1 will first enter the plate heat exchanger 3 and then enter the condenser 8. The heat carried by the high-temperature and high-pressure gas will be transferred to the plate heat exchanger 3 and heat the syrup in the fructose storage bin 10 to ensure that it is always in a flowable liquid state; if the temperature sensor 11 detects that the temperature reaches the preset high temperature value, the control system will automatically control the first solenoid valve 6 to close and the second solenoid valve 7 to open, and the plate heat exchanger 3 will not work.
