Technical Field
[0001] The present application relates to the technical field of dual-mode refrigeration devices, and in particular to a dual-mode refrigeration device. Background Art
[0002] Water is an essential commodity in daily industry and life. It involves all aspects of people's lives. When using water in daily life, users usually have different requirements for water temperature in different occasions. Customers who have high requirements for water temperature changes usually need to set up two circulation loops of cooling and heating devices in their water devices. During use, customers choose water for heating or cooling devices according to their own needs, or mix the water flow of heating and cooling devices in proportion to obtain water of corresponding temperature.
[0003] In the prior art, in order to ensure that the water in the refrigeration device has a certain volume, a water tank is usually installed on the refrigeration device. However, the water tank participates in the circulation of water on the refrigeration device, which increases the refrigeration capacity of the refrigeration device and thus consumes more energy. There is room for improvement.
[0004] To this end, the present application provides a dual-mode refrigeration device. Utility Model Content
[0005] In response to the shortcomings of the existing technology, the present application provides a dual-mode refrigeration device, which overcomes the shortcomings of the existing technology and aims to solve the problem in the existing technology that, in order to ensure that the water in the refrigeration device has a certain volume, a water tank is usually installed on the refrigeration device, but the water tank participates in the circulation of water on the refrigeration device, which increases the refrigeration capacity of the refrigeration device and thus consumes more energy, leaving room for improvement.
[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a dual-mode refrigeration device, comprising a frame, a partition plate fixedly installed inside the frame, a refrigerator fixedly installed on the top of the partition plate, a refrigeration pipe fixedly installed on the top of the refrigerator, an electric heater fixedly installed on the bottom of the partition plate, a heating pipe fixedly installed on the bottom of the electric heater, a pad fixedly installed on the top of the partition plate on one side of the refrigerator, an expansion water tank fixedly installed above the pad, a first expansion pipe connected between the refrigerator and the expansion water tank, a second expansion pipe connected between the electric heater and the expansion water tank, and a circulation pipe is provided inside the frame.
[0007] By adopting the above technical solution, the refrigerator is connected to the external water supply pipe, and the refrigerator starts working to lower the water temperature. When heating is needed, the electric heater is turned on to start working to increase the water temperature. During this working process, the electric heater heats the water and the water expands. Under the action of the second expansion tube, the expansion water tank can absorb this part of the excess water to prevent the pressure of the device from being too high, or when the water level in the refrigerator drops, due to the pressure difference caused by the height difference, the expansion water tank automatically replenishes water into the refrigerator through the first expansion tube. At the same time, the expansion water tank is installed at a high position and does not participate in the water circulation, so that the cooling time of this device is accelerated, which is beneficial to reduce energy consumption.

The pumped water is controlled by the double-headed valve and selectively passes through the cold water pipe or the hot water pipe. The treated water then enters the buffer tank through the cooling pipe or the heating pipe and circulates under the action of the circulation pipe. At the same time, the buffer tank plays the role of storing, regulating and balancing the water volume in the whole process, which is conducive to the stable operation of the device under different working conditions.
[0010] As a preferred technical solution of the present application, a liquid storage tank is fixedly installed on the bottom of the frame on one side of the buffer tank, and a first delivery pipe is connected between the liquid storage tank and the refrigerator.
[0011] By adopting the above technical solution, the liquid storage tank stores the refrigerant required by the refrigerator. When the refrigerator needs to be refrigerated, the corresponding refrigerant will be promptly transported and replenished to the refrigerator through the first delivery pipe, thereby improving practicality during use.

[0019] By adopting the above technical solution, the external pipeline is connected to the expansion water tank through the overflow pipe. When the water level in the expansion water tank exceeds the overflow pipe, the overflow pipe automatically discharges the excess water into the expansion water tank, thereby improving practicality during use.
[0020] Beneficial effects of this application:
[0021] By connecting the external water supply pipe to the refrigerator, the refrigerator starts working to lower the water temperature. When heating is needed, the electric heater is turned on to start working to increase the water temperature. During this working process, the electric heater heats the water and the water expands. Under the action of the second expansion pipe, the expansion water tank can absorb this part of the excess water to prevent the pressure of this device from being too high. When the water level in the refrigerator drops, due to the pressure difference formed by the height difference, the expansion water tank automatically replenishes water into the refrigerator through the first expansion pipe. At the same time, the expansion water tank is installed at a high position and does not participate in the water circulation, which speeds up the cooling time of this device and helps to reduce energy consumption.

The pumped water is controlled by the double-head valve and selectively passes through the cold water pipe or the hot water pipe.
