As shown in fig. 1 and 2, a soda water preparation assembly according to an embodiment of the present invention includes: refrigeration case 250, refrigeration system, heat exchange water pipe 404, soda tank 420 and carbon dioxide supply.

Wherein, refrigeration case 250 limits the accommodation space who is used for holding heat transfer medium, and the shape of refrigeration case 250 can be cuboid shape, cylindrical etc. and the heat transfer medium in refrigeration case 250 is used for exchanging heat with heat transfer water pipe 404 and soda jar 420, makes soda jar 420 keep in the low temperature state on the one hand, and the carbon dioxide in soda jar 420 is difficult for following aquatic the dissipation like this, and on the other hand makes the temperature of the water of flowing through heat transfer water pipe 404 reduce. The heat exchange medium in the refrigeration box 250 may be water or sand, and the heat exchange medium in the refrigeration box 250 is preferably water, so that the heat exchange medium is easily supplemented.

The refrigeration cassette 250 may include a multi-layer housing to achieve the thermal insulation effect. For example, the refrigeration box 250 may include an inner layer, a heat insulating layer, and an outer layer, the inner layer may be made of steel plates or plastic members, the heat insulating layer may be a foamed structure, and the outer layer may be made of steel plates or plastic members.

The refrigeration system is used for refrigerating the heat exchange medium in the refrigeration box 250, and the refrigeration system may include a refrigeration loop formed by connecting a compressor, a condenser, a capillary tube, and an evaporator 430, wherein the evaporator 430 is installed in the accommodation space, and the evaporator 430 is used for refrigerating the heat exchange medium in the refrigeration box 250; or the refrigeration system may include semiconductor refrigeration fins.

For example, when the heat exchange medium is water, the heat exchange water pipe 404 is immersed in the water, and when the heat exchange medium is sand, the heat exchange water pipe 404 is buried in the sand.

The heat exchange water pipe 404 may be made of a good heat conductor, such as a stainless steel pipe or copper pipe, preferably a stainless steel pipe, so that the water supply is safer and more sanitary.

Soda tank 420 is installed in the accommodating space, and at least a part of the wall surface of soda tank 420 is wrapped by the heat exchange medium in the accommodating space, for example, the other wall surfaces of soda tank 420 except the top cover may be all wrapped by the heat exchange medium in the accommodating space.

For example, the water inlet and outlet ports of the second water pump 403 may be connected to the edge region and the middle region of the refrigeration cassette 250, respectively, to mix water uniformly.

In some embodiments, one of the water inlet 403a and the water outlet 403b of the second water pump 403 is connected to an upper portion of the refrigeration cassette 250, and the other is connected to a lower portion of the refrigeration cassette 250.

The water level detection device 223, the water inlet control valve 303, the first water pump 402, the second water pump 403, the third water pump 230, the water replenishing valve 401, the hot water supply control valve 106, the cold water supply control valve 107, the normal temperature water supply control valve 108, the soda water supply control valve 109, and the switching valve 320 are electrically connected to the controller 610.

The controller 610 may be installed at a side of the water maker, the display 620 may be installed at a front of the water maker, for example, above the water supply inlet, the display 620 may display the current operation state of the water maker, or the display 620 may be touch-controlled for performing control input.

The water replenishing process of the water producing apparatus according to the embodiment of the present invention will be described with reference to fig. 6.

As shown in fig. 6, when the controller 610 determines that the water producing apparatus is first powered on, the controller 610 controls the water inlet control valve 303 based on the water level information of the water reservoir 220 detected by the water level detecting means 223, and controls the third water pump 230 to be turned off, in other words, preferentially replenish water into the water reservoir 220, before the water level detecting means 223 first detects that the water level of the water reservoir 220 reaches the target water level.

In the water tank supplement mode, the controller 610 controls the third water pump 230 to be turned off, and the controller 610 controls the water inlet control valve 303 to be turned on until it is determined that the water level of the water tank 220 detected by the water level detecting means 223 reaches the target water level. In the water replenishing mode of the water storage tank, the third water pump 230 is closed, the water inlet control valve 303 is kept opened to replenish water to the water storage tank 220, and when the water level of the water storage tank 220 reaches the target water level, the controller 610 controls the water inlet control valve 303 to be closed and enters the water replenishing mode of the water making module. In the tank refill mode, the hot water supply control valve 106, the cold water supply control valve 107, the normal temperature water supply control valve 108, and the soda water supply control valve 109 are closed.

In the heating module replenishing mode, the third water pump 230 is operated to pump water from the water storage tank 220 to the heating water tank 240 and the cooling water tank 250, and when the water level of the water storage tank 220 drops below the target water level, the water inlet control valve 303 is opened to replenish the water storage tank 220, thus ensuring that the water storage tank 220 has enough water to be supplied to the heating water tank 240 and the cooling water tank 250. In the water-replenishing mode of the water-producing module, the air in the water-producing tank 240 and the refrigerating tank 250 flows into the water storage tank 220 through the water return port of the water-producing module. In the water replenishing mode of the water producing module, the hot water supply control valve 106, the cold water supply control valve 107 and the normal temperature water supply control valve 108 are closed. The first port 321 and the third port 323 of the switching valve 320 communicate with each other.

As shown in fig. 7, the controller 610 is configured to determine that the water level detection device 223 detects that the water level of the water reservoir 220 is maintained above the target water level for the target period of time, and determine that the water replenishing mode of the water generation module is finished. When the water levels in the heating water tank 240 and the cooling water tank 250 reach the target positions, the water in the water storage tank 220 is pumped from the third water pump 230 to the heating water tank 240 and the cooling water tank 250, and the water in the water production module flows back to the water storage tank 220 from the water return ports of the heating water tank 240 and the cooling water tank 250, so that the water in the water storage tank 220 can be kept basically unchanged. Therefore, the water level is kept above the target water level within the target time period, the water supplementing mode of the water making module is determined to be finished, the third water pump 230 is closed, the water making module is opened, and the valve ports of the switching valve 320 are not communicated with each other.

In summary, the water production apparatus according to the embodiment of the present invention designs the above-mentioned circulation water path, and uses the third water pump 230 to replenish water to the water production module, and the duration of the water storage tank 220 maintaining the target water level can automatically determine whether water replenishment of the water storage tank 220 and the water production module is completed, so as to effectively prevent dry burning or freezing.

The controller 610 controls the hot water discharge control valve 304 to be opened, controls the cold water discharge control valve 305 to be opened, and turns on the third water pump 230, and after a target time, the water reservoir 220 may be drained. The target time is related to the capacity of the reservoir 220 and the flow rate of the third water pump 230 while considering the different resistances caused by the pipe lengths.

After the water tank 220 is drained, the controller 610 turns off the third water pump 230, continues to keep the hot water discharge control valve 304 open, controls the cold water discharge control valve 305 to open, and drains the hot water tank 240 and the refrigerant tank 250 by gravity.

The controller 610 controls the hot water discharge control valve 304 to be opened, controls the cold water discharge control valve 305 to be opened, and turns on the third water pump 230, and after the first target time, the water reservoir 220 may be drained. The first target time is related to the capacity of the water reservoir 220 and the flow rate of the third water pump 230 while considering the different resistances caused by the pipe lengths.

After the water tank 220 is drained, the controller 610 turns off the third water pump 230, continues to keep the hot water discharge control valve 304 open, controls the cold water discharge control valve 305 to open, and after a second target time, drains the heating water tank 240 and the cooling tank 250 by using gravity.

cooling water tanks

240 and 250. In the water-replenishing mode of the water-producing module, the air in the water-producing tank 240 and the refrigerating tank 250 flows into the water storage tank 220 through the water return port of the water-producing module. In the tank refill mode, the hot water supply control valve 106, the cold water supply control valve 107, and the normal temperature water supply control valve 108 are closed. The first port 321 and the third port 323 of the switching valve 320 communicate with each other.

The controller 610 is configured to determine that the water level of the water tank 220 detected by the water level detecting device 223 is maintained above the target water level within the target time period, and then determine that the water tank 220 and the water production module are both full of water, and the third water pump 230 continues to operate, so that the water with the cleaning agent circulates and flows between the water tank 220, the water production module and the circulation pipeline, or of course, the third water pump 230 may be added and shut down, and the cleaning is performed in a static soaking manner.
