The soda canister 64 is located within the water storage tank 56. In the present invention, since the purified water is disposed in the water storage tank 56 through the separate purified water line 57, and is disposed independently of the evaporator 55 located in the water storage tank 56, the evaporator 55 is not directly in contact with the purified water, the evaporator Contaminants such as bacterial dust on the surface of the 55, even when the refrigerant in the evaporator 55 leaks, do not pollute the purified water in the purified water pipe 57, thereby ensuring the quality of the purified water in the purified water pipe 57. It also has the effect of a large amount of cold storage. Meanwhile, since the soda water tank 64 is located in the water storage tank 56, the soda water tank 64 is immersed in a heat transfer medium such as water, so that the soda water in the soda water tank 64 can be further cooled by the evaporator 55, thereby causing the soda water to cool. better. In addition, the evaporator 55, the water purification line 57, and the soda water tank 64 are all disposed in the water storage tank 56, so that these components form an integral module, and only need to be installed through the water storage tank 56 and the soda machine housing. This enables modular installation, which simplifies installation steps and enables quick installation.

In the embodiment of the present invention, the evaporator 55 is spaced apart from the water purification pipe 57, so that the water purification pipe 57 can be prevented from being too close to the evaporator 55, so that the temperature is too low.

Cooling to increase the cooling effect of soda. Meanwhile, if the soda water tank 64 is located between the water purification line 57 and the evaporator 55, the soda water tank 64 will be preceded by the water purification line 57 with the evaporator 55. In the heat exchange, the water purification pipe 57 obtains less cold in a portion adjacent to the soda water tank 64, and the portion farther away from the soda water tank 64 obtains more cold, so the net The respective positions of the water line 57 are inconsistent with the heat exchange condition of the evaporator 55, resulting in uneven temperature throughout the water purifying line 57. In the embodiment of the present invention, the soda water tank 64 is located in the area enclosed by the water purification pipe 57, which can avoid the occurrence of the above phenomenon, thereby ensuring the temperature of the water purification pipe 57. Uniformity.

In order to further improve the uniformity of temperature throughout the water purification line 57, a submersible pump is also disposed in the water storage tank 56. In this embodiment, by controlling the operation of the submersible pump, the heat transfer medium in the water storage tank 56 can be agitated, so that the heat transfer medium at each position, such as water, is mixed, so that the temperature of the heat transfer medium at each position is further increased. Uniform, that is, the amount of cooling exchanged between the water purification line 57 and the heat transfer medium is relatively uniform.
