Description

Technical Field

[0001] The utility model relates to the technical field of water dispensers, in particular to an instant cooling and heating water dispenser. Background Art

[0002] In the hot summer, people like to drink ice water to cool off. In the cold season, hot water is a daily need of people. Therefore, the market demand for water dispensers that can provide both ice water and hot water is growing. There are two types of ice water dispensers on the market, one is the storage type and the other is the instant cooling type. However, the existing instant cooling water dispensers have to wait for 10 to 20 minutes to produce ice water after starting up, which is not really instant cooling, and the water output is small, which cannot meet the water demand.

[0003] CN103919463B discloses an instant hot and cold water dispenser, comprising a seat with an inner cavity, a water slot for placing a kettle on the top of the seat, a water outlet faucet at the front end of the seat, and a water pump 1, a water pump 2, a hot runner unit and a cold runner unit inside the seat. This type of storage water dispenser stores drinking water in a sealed inner cavity or inner tank, but the sealed inner cavity or inner tank is inconvenient to clean or is not cleaned thoroughly, and the remaining water will cause secondary pollution, affect the water quality and endanger human health. At the same time, in order to increase the water output, the only method is to increase the volume of the inner tank and use a high-power compressor, which makes the ice water dispenser have the problems of large size, high energy consumption and stale water quality. In addition, the hot water dispensers on the market only obtain hot water by electric heating, and the energy consumption is relatively large. Utility Model Content

[0004] The utility model aims to solve the technical problems existing in the prior art, and particularly innovatively proposes an instant cooling and heating water dispenser, which can meet the needs of instant cooling and heating and reasonably utilize energy.

[0005] In order to achieve the above-mentioned purpose, the utility model provides an instant cold and hot water dispenser, including a refrigeration system, a hot water supply system and an ice water supply system, wherein the hot water supply system and the ice water supply system both include a heat exchange box, wherein a refrigerant coil and a water pipe are spirally arranged in the heat exchange box, and the starting ends of the water pipes are both connected to normal temperature drinking water pipes; the heat exchange boxes of the hot water supply system and the ice water supply system are respectively filled with heat storage materials and ice cold storage materials, wherein the water pipes of the hot water supply system and the ice water supply system are respectively hot water coils and ice water coils, and the refrigerant coils of the hot water supply system and the ice water supply system are respectively preheating refrigerant coils and ice water refrigerant coils;

[0006] The starting end of the ice water refrigerant coil is connected to the refrigerant liquid inlet pipe of the refrigeration system, and the end is connected to the compressor return pipe of the refrigeration system to form a loop; the end of the ice water coil is connected to the ice water outlet pipe;

[0007] The starting end of the preheating refrigerant coil is connected to the refrigerant exhaust pipe of the compressor, and the end is connected to the auxiliary condenser of the refrigeration system through the refrigerant connecting pipe to form a loop, and the heat of the refrigerant is exchanged with the heat storage material, and the heat of the refrigerant is stored in the heat storage material to preheat the drinking water in the hot water coil of the hot water supply system;

[0008] The hot water supply system also includes an electric heating box, in which a temperature detector and an electric heater are arranged, and a hot water outlet pipe is arranged on the electric heating box; the end of the hot water coil of the hot water supply system is connected to the electric heating box to allow water to directly enter the electric heating box for secondary heating;

[0009] Alternatively, the end section of the hot water coil of the hot water supply system is coiled in the electric heating box, and the electric heating wire of the electric heater is wound outside the end section of the water pipe of the hot water supply system.

[0010] The working principle is as follows: the refrigerant is compressed in the compressor and becomes a high-temperature and high-pressure gas, then flows through the heat accumulator, releasing heat to the heat storage material in the hot water supply system, and then the refrigerant passes through the auxiliary condenser to further dissipate heat and condense into a high-pressure liquid, and then enters the throttle valve, the pressure drops sharply, and the temperature also drops accordingly, becoming a low-temperature and low-pressure refrigerant wet steam, and then flows through the ice water supply system to cool the ice storage material until it changes phase and freezes, and finally the refrigerant returns to the compressor to start a new cycle.

[0011] Thermal storage materials are used to store most of the condensation heat of the refrigerant, preheat the drinking water when making hot water, and reduce energy consumption. Ice storage materials are used to store cold energy and quickly cool drinking water when ice water is needed. The refrigeration system can be stopped when all the ice storage materials are frozen. In order to save operating costs, it is advisable to use low-peak electricity at night to make ice.

[0012] When ice water is needed, normal temperature drinking water flows through the ice water inlet valve, enters the ice storage heat exchange box, and is quickly cooled by the low-temperature ice storage material therein to obtain ice water. The temperature and flow of ice water can be accurately controlled by adjusting the opening of the ice water inlet valve. When making ice water, the refrigeration system does not need to be operated. When hot water is needed, normal temperature drinking water enters the preheating box through the hot water inlet valve, absorbs the heat of the heat storage material for preheating, and then is accurately temperature-controlled by the electric heater of the electric heating box to obtain hot water of various temperatures. The utility model can quickly provide hot and cold drinking water, improves energy utilization efficiency through the use of ice storage materials and heat storage materials, and ensures a continuous supply of hot and cold water.

[0013] In the above scheme: the heat exchange box of the ice water supply system is an ice storage heat exchange box, and the heat exchange box of the hot water supply system is a preheating box. The ice storage heat exchange box and the preheating box are fixed together, and a heat insulation layer is sandwiched between the ice storage heat exchange box and the preheating box. The heat insulation layer can avoid heat exchange between the two as much as possible, ensuring the cooling and heating effects.

[0014] In the above scheme: the ice storage heat exchange box and the preheating box are arranged on the left and right, and the electric heating box is arranged below the preheating box, which is convenient for running pipelines and makes the whole more tidy.

[0015] In the above scheme: the top of the ice storage heat exchange box is flush with the top of the preheating box, the bottom of the ice storage heat exchange box is flush with the bottom of the electric heating box, and the bottom of the insulation layer extends between the bottom of the ice storage heat exchange box and the electric heating box.

[0016] In the above scheme: the refrigeration system also includes a condenser liquid outlet pipe connected to the auxiliary condenser, the auxiliary condenser is also provided with a condenser fan, the other end of the condenser liquid outlet pipe is connected to the refrigerant liquid inlet pipe, the refrigerant liquid inlet pipe is sequentially provided with a drying filter and a throttling device along the refrigerant flow direction, the compressor return pipe is connected to the compressor return end, and the compressor return pipe is also provided with a gas-liquid separator.

[0017] In the above scheme: the water pipes of the hot water supply system and the ice water supply system are hot water coils and ice water coils respectively, and the ice water coils and hot water coils are respectively provided with ice water inlet valves and hot water inlet valves to facilitate the adjustment of the amount of normal temperature drinking water entering.

[0018] In summary, the beneficial effects of the utility model are: meeting the needs of instant cooling and instant heating at the same time. The ice water supply system is set up, and drinking water at room temperature can be quickly cooled by passing through the ice storage heat exchange box. Ice water of 5-10°C and hot water of set temperature can be produced in 10-20 seconds. The water volume is at least 500ml per minute, and it is ready for use. The water quality is fresh, and there is no water storage tank or cold tank, which saves equipment space. The hot water supply system is set up to first heat the heat storage material through the heat of the refrigerant of the refrigeration system, and preheat the drinking water through the heat storage material. It can reduce the cooling amount of the auxiliary condenser to a certain extent, improve the cooling effect of the refrigerant, and improve the efficiency of the subsequent cold storage of the ice storage material. At the same time, it can also reduce the heating power of the subsequent secondary heating of the drinking water, which is energy-saving and environmentally friendly. The electric heating box is set up to ensure that the drinking water reaches the required temperature and improves practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be further described below by way of embodiments and in conjunction with the accompanying drawings:

[0022] like Figure 1 , 2 As shown, an instant cold and hot water dispenser includes a refrigeration system, a hot water supply system and an ice water supply system.

[0023] The refrigeration system includes a compressor 1, the outlet of which is connected to the beginning of a preheating refrigerant coil 3 through a refrigerant exhaust pipe 2.

[0024] The auxiliary condenser 5 is connected to the condenser liquid outlet pipe 7, and the other end of the condenser liquid outlet pipe 7 is connected to the refrigerant liquid inlet pipe 10. A drying filter 8 and a throttling device 9 are sequentially arranged on the refrigerant liquid inlet pipe 10 along the refrigerant flow direction.

A gas-liquid separator 13 is also arranged on the compressor return pipe 12.

[0025] The hot water supply system includes a hot water coil 24, a preheating box 23 and an electric heating box 25. The preheating refrigerant coil 3 and the hot water coil 24 are both coiled in the preheating box 23, and the preheating box 23 is also filled with a heat storage material. The heat of the refrigerant is exchanged with the heat storage material through the preheating refrigerant coil 3, and the heat of the refrigerant is stored in the heat storage material to preheat the hot water coil 24. The starting end of the hot water coil 24 is connected to the normal temperature drinking water pipe, and the end of the hot water coil 24 is connected to the electric heating box 25. The electric heating box 25 is used for secondary heating. A temperature detector and an electric heater 26 are arranged in the electric heating box 25, and a hot water outlet pipe 20 is arranged on the electric heating box 25.

[0026] The electric heating box 25 may be provided with a heating water cavity therein, the hot water coil 24 is connected to the heating water cavity, and the hot water outlet pipe 20 is connected to the heating water cavity. Alternatively, the hot water coil 24 may pass through the electric heating box 25 and directly connect to the hot water outlet pipe 20, while the heating resistance wire of the electric heater 26 is wound around the hot water coil 24. Both of the above methods are conventional technical means, and can be installed at will according to specific needs.

[0027] The ice water supply system includes an ice water coil 18 and an ice cold storage heat exchange box 17. The ice water refrigerant coil 11 and the ice water coil 18 are spirally arranged in the ice cold storage heat exchange box 17. The ice cold storage heat exchange box 17 is filled with ice cold storage material. The beginning of the ice water coil 18 is connected to the normal temperature drinking water pipe, and the end of the ice water coil 18 is connected to the ice water outlet pipe 19. Both the heat storage material and the ice cold storage material are phase change materials.

[0028] In order to save space occupied by the equipment, the ice storage heat exchange box 17 and the preheating box 23 are spaced and fixed together, and an insulation layer 27 is sandwiched between the ice storage heat exchange box 17 and the preheating box 23, which can avoid heat exchange between the two as much as possible through the insulation layer 27 to ensure the cooling and heating effects. The electric heating box 25 is arranged below the preheating box 23, and the end of the hot water coil 24 can be directly connected to the electric heating box 25, which is convenient for running pipelines and is more tidy as a whole. Specifically, the top of the ice storage heat exchange box 17 is flush with the top of the preheating box 23, the bottom of the ice storage heat exchange box 17 is flush with the bottom of the electric heating box 25, and the bottom of the insulation layer 27 extends to between the bottom of the ice storage heat exchange box 17 and the electric heating box 25. The ice water coil 18 and the hot water coil 24 are respectively provided with an ice water inlet valve 16 and a hot water inlet valve 22, which is convenient for adjusting the amount of normal temperature drinking water entering.

[0029] When the refrigeration system is working: the refrigerant is compressed into a high-temperature and high-pressure gas in the compressor 1, enters the preheating refrigerant coil 3 in the preheating box 23 through the refrigerant exhaust pipe 2 to release heat, and then enters the auxiliary condenser 5 through the refrigerant connecting pipe 4 to further release heat and condense into a high-pressure liquid. In the auxiliary condenser 5, the heat is dissipated into the air through the condenser fan 6, and enters the drying filter 8 through the condenser liquid outlet pipe 7 to remove impurities and moisture. The high-pressure liquid refrigerant passes through the throttling device 9, and the pressure and temperature drop sharply, turning into low-temperature and low-pressure wet steam. Then it enters the ice water refrigerant coil 11 of the ice storage heat exchange box 17 through the refrigerant inlet pipe 10, and absorbs the heat of the ice storage material outside the coil. The refrigerant absorbs heat and turns into steam. The refrigerant steam enters the refrigerant gas-liquid separator 13 through the compressor return pipe 12 to separate the droplets in the gaseous refrigerant, ensuring that only the gaseous refrigerant returns to the compressor 1 to complete the cycle.

[0030] When ice water is needed, normal temperature drinking water enters the ice water supply system through the normal temperature drinking water inlet pipe 14, passes through the ice water inlet pipe 15 and the ice water inlet valve 16, and flows into the ice water coil 18 in the ice storage heat exchange box 17, is cooled by the ice storage material outside the ice water coil to become ice water, and is finally output through the ice water outlet pipe 19.

[0031] When hot water is needed, normal temperature drinking water enters the hot water supply system through the normal temperature drinking water inlet pipe 14, passes through the hot water inlet pipe 21 and the hot water inlet valve 22, and flows into the hot water coil 24 in the preheating box 23, is preheated by the heat storage material outside the pipe, and then enters the electric heating box 25, is heated again to the required temperature by the electric heater 26 therein, and is finally output through the hot water outlet pipe 20.
