The invention provides a soda water machine which comprises a water storage tank, a cold water pipe, an evaporator and a soda water tank, wherein the cold water pipe, the evaporator and the soda water tank are arranged in the water storage tank, the water inlet end of the cold water pipe is connected with a purified water source, and the water outlet end of the cold water pipe is connected with a water inlet hole of the soda water tank. Based on the soda water machine, the invention also provides a waterway control method of the soda water machine.
In the embodiment of the invention, as shown in fig. 1, the waterway control method of the soda water machine comprises the following steps:
s10, detecting the real-time water level in the water storage tank through a water level detection piece arranged in the water storage tank;
S20, when the real-time water level is lower than a preset water level lower limit value, the control device controls the water storage tank to feed water;
And S30, when the real-time water level reaches a preset water level upper limit value, the control device controls the water storage tank to stop water inflow.
In the embodiment of the invention, the water level detection member can be a floater, a water level probe and the like. The water level detection part detects the water level in the water storage tank in real time so as to avoid the phenomenon that the water level in the water storage tank is too low, and the cold water pipe and the evaporator part are exposed on the water surface, so that the refrigeration effect is poor; meanwhile, the phenomenon that water overflows due to the fact that the water level in the water storage tank is too high can be avoided.
In step S20, the control device controls the water storage tank to supply water, and in step S30, the control device controls the water storage tank to stop supplying water, which is specifically implemented by the following ways:
In some embodiments, a water inlet valve is arranged on a water inlet pipe of the water storage tank, and the control device controls the water storage tank to inlet water by controlling the water inlet valve to be opened; and the control device controls the water storage tank to stop water inflow by controlling the water inlet valve to be closed.
In other embodiments, a water pump is arranged on a water inlet pipe of the water storage tank, and the control device controls the water pump to work so as to pump outside water into the water storage tank, thereby controlling the water inlet of the water storage tank; and the control device controls the water pump to stop working, so as to control the water storage tank to stop water inflow.
In general, when the water level in the water storage tank reaches the upper limit value of the water level, the cold water pipe and the evaporator can be completely immersed in water.
According to the invention, the water level in the water storage tank is detected in real time, and when the water level in the water storage tank is lower than the preset lower limit value of the water level, the control device controls the water storage tank to feed water, so that the phenomenon that the water level in the water storage tank is too low, and the cold water pipe and the evaporator are exposed on the water surface, so that the refrigeration effect is poor can be avoided. When the water level in the water storage tank reaches the preset water level upper limit value, the control device controls the water storage tank to stop water inlet, so that the phenomenon that water overflows due to the fact that the water level in the water storage tank is too high can be avoided.
Further, as shown in fig. 2, the waterway control method of the soda water machine further includes the following steps:
s41, the control device records the single water inlet time length of the water storage tank;
And S42, when the single water inlet time length reaches a preset time length, the control device controls the water storage tank to stop water inlet.
In step S41, the single water inlet of the water storage tank means that the water storage tank starts to be filled until the water inlet is stopped, and when the water storage tank is filled next time, the system is re-timed. Preferably, the single water inlet time is the working time of a water pump of the water storage tank. By recording the working time of the water pump, accurate water inlet time can be obtained, and erroneous judgment is prevented.
In this embodiment, the purpose of recording the single water intake time of the water tank is to prevent the water tank from always intake due to inaccurate water level detection results when the water level detection member fails. In this case, it is preferable that the water level in the water storage tank is allowed to rise at least from the lower limit value to the upper limit value.
Further, as shown in fig. 3, the waterway control method of the soda water machine further includes the following steps:
S51, the control device records the using time of the soda water machine;
and S52, when the using time reaches the preset time, the control device controls the drain pipe of the water storage tank to drain water.
In the above steps, when the control device controls the water storage tank to drain, the previous use time length is reset to zero, and the control device restarts to record the use time length of the soda water machine. Preferably, the duration of use is from 15 days to 30 days.
Specifically, in step S52, when the usage time reaches a preset period, the control device issues a drainage command to control the drain valve on the drain pipe to be opened so as to drain the water storage tank, thereby replacing the water in the water storage tank and preventing the water in the water storage tank from growing a large amount of bacteria due to long-time standing.
Further, as shown in fig. 4, the waterway control method of the soda water machine further includes the following steps:
S61, when a starting-up instruction is received, the control device controls the heating piece to stop working and controls the hot water tank to feed water;
And S62, when the water full signal of the hot water tank is received, the control device controls the hot water tank to stop water inflow.
Preferably, the hot water tank in the embodiment of the invention is a pressure tank, a hot water valve is arranged at a normal temperature water inlet of the hot water tank, and the hot water valve is controlled to be opened so as to enable the hot water to flow into the hot water tank, so that the pressure in the hot water tank is increased, and the original water in the hot water tank is extruded from a hot water outlet of the hot water tank. And the hot water valve is controlled to be closed, so that the inflow of the hot water into the hot water tank is prevented, and the water in the hot water tank cannot flow out when the pressure in the hot water tank is low. Therefore, the water inlet of the hot water tank in the step S61 is specifically controlled by controlling the hot water valve to open, and the water inlet stopping of the hot water tank in the step S62 is controlled by controlling the hot water valve to close.
In step S61, when a start-up command is received, the control device controls the heating element to stop working, so that the phenomenon of dry heating of the heating element due to insufficient water in the hot water tank can be avoided, and the safety performance can be improved. Meanwhile, when a starting instruction is received, the water inlet of the hot water tank is controlled so as to ensure that the hot water tank can be in a full water state.
In step S62, when the hot water tank water outlet is detected, the hot water tank water full signal is considered to be received. Specifically, a pressure sensor for detecting the pressure at the hot water outlet is arranged at the hot water outlet of the hot water tank, and when the pressure detected by the pressure sensor is greater than the preset pressure, the water in the hot water tank flows out, and the control device is considered to receive a water full signal of the hot water tank. Of course, in other embodiments, the hot water tank water full signal is deemed received when it is detected that the water level in the hot water tank reaches a high level value. Specifically, a water level detection part for detecting the water level of the hot water tank is arranged in the hot water tank, and when the water level in the hot water tank reaches a high water level value, the control device is regarded as receiving a water full signal of the hot water tank.
In this embodiment, by detecting whether the hot water tank is full when the soda water machine is used for the first time, it is possible to ensure that the hot water tank is in a full water state when heating, avoiding dry heating.
Further, as shown in fig. 5, the waterway control method of the soda water machine further includes the following steps:
s71, when a heating instruction is received, judging whether the control device receives a water full signal of the hot water tank or not;
s72, if yes, the control device controls the heating element to work and controls the hot water tank to stop water inflow;
and S73, if not, the control device controls the heating element to stop working and controls the hot water tank to feed water.
In step S71, when a heating command is received, it is determined whether the control device receives a water full signal of the hot water tank, so that dry heating of the hot water tank due to less water can be avoided, and thus the use safety of the soda water machine can be improved.
In step S72, when the water full signal of the hot water tank is received, the control device controls the heating element to work so as to heat the water of the hot water tank. In addition, when the water in the hot water tank is heated to a preset temperature, and after the control device receives a hot water consumption instruction, the control device controls the hot water valve to be opened so that the hot water flows out.
In step S73, when the water full signal of the hot water tank is not received, the control device controls the heating element to stop working, so as to avoid dry heating. Meanwhile, the control device also controls the water inlet of the hot water tank until the control device receives the water full signal of the hot water tank, then controls the hot water tank to stop water inlet and controls the heating element to work.
Further, the waterway control method of the soda water machine further comprises the following steps:
When a water consumption instruction of the normal temperature water is received, the control device controls the normal temperature module to discharge water;
when a cold water use instruction is received, the control device controls the cold water module to discharge water;
when a hot water using instruction is received, the control device controls the hot water module to discharge water;
when receiving the soda water use instruction, the control device controls the soda water module to discharge water.
Specifically, the soda water machine comprises a filtering module, a normal temperature module, a cold water module, a hot water module and a soda water module; the cold water module comprises the water storage tank, a cold water pipe and an evaporator; the hot water module includes the hot water tank and the soda water module includes the soda water tank. The water inlet side of the filtering module is communicated with an external water source, and the water outlet side of the filtering module is communicated with the water inlet side of the normal-temperature module. The water outlet side of the normal temperature module is respectively connected with the water inlet end of the cold water pipe and the hot water tank, and meanwhile, the water outlet side of the normal temperature module is communicated with the outside through the normal temperature water pipe so as to provide normal temperature water for a user, and the normal temperature water pipe is provided with a normal temperature water valve. The water outlet end of the cold water pipe is connected with the water inlet hole of the soda water tank, and the water outlet end of the cold water pipe is also connected with the outside through a cold water outlet pipe so as to provide cold water for users. And a cold water valve is arranged on the cold water outlet pipe. The soda water tank is characterized in that a soda water pipe is arranged at a water outlet of the soda water tank and is communicated with the outside to provide soda water for a user, and a soda water valve is arranged on the soda water pipe.
In the above, the control device controls the normal temperature water outlet of the normal temperature module by controlling the normal temperature water valve to be opened specifically so as to provide the normal temperature water for a user; when a normal-temperature water stop instruction is received, the control device controls the normal-temperature water valve to be closed.
The control device controls the cold water module to discharge water by controlling the cold water valve to be opened specifically so as to provide cold water for users; when receiving a cold water stop instruction, the control device controls the cold water valve to be closed.
The control device controls the water outlet of the hot water module by controlling the hot water valve to be opened so as to provide hot water for a user; when receiving a hot water stop instruction, the control device controls the hot water valve to be closed.
The control device controls the soda water module to discharge water specifically by controlling the soda water valve to open so as to provide soda water for a user; when receiving the soda water stop instruction, the control device controls the soda water valve to be closed.
Meanwhile, a water level probe is further arranged in the soda water tank and used for detecting the water level of the soda water tank, and when the water level in the soda water tank is lower than the lower limit value of the water level, the control device controls the soda water tank to feed water; when the water level in the soda water tank reaches the upper limit value of the water level, the control device controls the soda water tank to stop water inflow.

The water inlet hole, the water outlet hole and the pipelines on the air inlet hole of the soda water tank 21 are all arranged outside the water storage tank 11 in a penetrating way, preferably in a sealing way. Similarly, both ends of the evaporator 12 are also disposed outside the water storage tank 11.
Typically, the soda machine further comprises a filter module 50, the water outlet side of the filter module 50 constituting a source of clean water. The water inlet end of the cold water pipe 13 passes through the water storage tank 11 and is communicated with the water outlet side of the filtering module 50. The soda water module further comprises a gas tank 25, wherein the gas tank 25 is communicated with the gas inlet hole through a water inlet pipeline so as to provide carbon dioxide gas for the soda water module. Of course, the intake holes of the soda tank 21 may also be in communication with an external air source. The soda machine also includes a compressor connected to the evaporator 12.
The water storage tank 11 is filled with water as a heat transfer medium. In some embodiments, the water storage tank 11 is communicated with a water inlet pipeline of the soda water machine so as to realize automatic water inlet and supplement the heat transfer medium for the water storage tank 11. Preferably, the water storage tank 11 is communicated with the water outlet side of the filtering module 50, so that the water flowing into the water storage tank 11 is filtered water, and the deposition of impurities in the water storage tank 11 can be reduced.
Specifically, the purified water filtered by the filtering module 50, or the external purified water, enters the cold water pipe 13 of the cold water module; the compressor turns on a refrigerating function, and a refrigerant circulates in the evaporator 12 to release cold; the cold water pipe 13 and the evaporator 12 exchange heat through water in the water storage tank 11, and purified water in the cold water pipe 13 is cooled to form cold water; the cold water is split into two paths after exiting from the water outlet end of the cold water pipe 13, one path is directly drunk by a user, and the other path is used for preparing soda water. When the soda machine is started to prepare soda water, the water inlet hole and the air inlet hole of the soda water tank 21 are both opened, the other path of cold water flows into the soda water tank 21 through the water inlet hole, and carbon dioxide gas also fills into the soda water tank 21 through the air inlet hole and is fully mixed with the cold water, so that soda water is prepared, and the prepared soda water flows out from the water outlet hole for users to drink.
In the invention, because the purified water is arranged in the water storage tank 11 through the independent cold water pipe 13 and is independently arranged with the evaporator 12 positioned in the water storage tank 11, the evaporator 12 is not in direct contact with the purified water, and pollutants such as bacterial dust on the surface of the evaporator 12, even when the refrigerant in the evaporator 12 leaks, the purified water in the cold water pipe 13 is not polluted, so that the quality of the purified water in the cold water pipe 13 can be ensured. Meanwhile, since the soda water tank 21 is located in the water storage tank 11, the soda water tank 21 is immersed in a heat transfer medium such as water, so that the soda water in the soda water tank 21 can be further cooled by the evaporator 12, thereby making the soda water more effective in refrigeration. In addition, the evaporator 12, the cold water pipe 13 and the soda water tank 21 are all arranged in the water storage tank 11, so that the components form an integral module, and the integral module is only required to be installed with the water purifier shell through the water storage tank 11, thereby realizing modularized installation, simplifying the installation steps and realizing the purpose of quick installation.
Referring to fig. 8 in combination, the soda water machine further includes:
a water level detecting member 60 disposed in the water storage tank 11 for detecting a real-time water level in the water storage tank 11; and

In the embodiment of the present invention, the water level detecting member 60 may be a float, a water level probe, etc. The water level detecting member 60 detects the water level in the water storage tank 11 in real time, so as to avoid the phenomenon that the water level in the water storage tank 11 is too low, and the cold water pipe 13 and the evaporator 12 are partially exposed on the water surface, resulting in poor refrigeration effect; meanwhile, the phenomenon of water overflow caused by the excessively high water level in the water storage tank 11 can be avoided.
In some embodiments, the water inlet valve 16 is arranged on the water inlet pipe of the water storage tank 11, and the control device 70 controls the water inlet valve 16 to be opened so as to control the water inlet of the water storage tank 11; and the control device 70 controls the water storage tank 11 to stop water inflow by controlling the water inlet valve 16 to be closed.
In other embodiments, a water pump is arranged on the water inlet pipe of the water storage tank 11, and the control device 70 controls the water pump to work so as to pump outside water into the water storage tank 11, thereby controlling the water inlet of the water storage tank 11; and the control device 70 controls the water storage tank 11 to stop water inflow by controlling the water pump to stop working.
In general, when the water level in the water storage tank 11 reaches the upper limit value of the water level, the cold water pipe 13 and the evaporator 12 can be completely immersed in water.
In the invention, by detecting the water level in the water storage tank 11 in real time, when the water level in the water storage tank 11 is lower than the preset lower limit value of the water level, the control device 70 controls the water storage tank 11 to feed water, so that the phenomenon that the water level in the water storage tank 11 is too low, the cold water pipe 13 and the evaporator 12 are exposed on the water surface, and the refrigerating effect is poor can be avoided. When the water level in the water storage tank 11 reaches the preset upper limit value of the water level, the control device 70 controls the water storage tank 11 to stop water feeding, so that the phenomenon that water overflows due to the fact that the water level in the water storage tank 11 is too high can be avoided.
Specifically, the control device 70 includes:
a timing unit 71 for recording a single water inlet time length of the water storage tank 11;
and a control unit 72, configured to control the water storage tank 11 to stop water intake when the single water intake duration reaches a preset duration.
The single water inlet of the water storage tank 11 means that the water storage tank 11 starts to be filled with water until the water is stopped, and when the water storage tank 11 is filled with water next time, the system is re-timed. Preferably, the single water inlet time period is the working time period of the water pump of the water storage tank 11. By recording the working time of the water pump, the accurate water inlet time can be obtained, and erroneous judgment is prevented.
In this embodiment, the purpose of recording the single water intake time period of the water storage tank 11 is to prevent the water storage tank 11 from being always intake due to inaccurate water level detection results when the water level detection member 60 fails. In this preset time period, it is preferable that the water level in the water storage tank 11 can be raised at least from the lower limit value to the upper limit value.
In order to facilitate the replacement of the water in the water storage tank 11, a water outlet is provided at the bottom of the water storage tank 11, and a water drain pipe is provided on the water outlet. In this embodiment, the timing unit 71 is further configured to record a usage period of the soda machine; the control unit 72 also controls the drain pipe of the water storage tank 11 to drain when the use time reaches a preset time period. Specifically, when the control device 70 controls the water storage tank 11 to drain, the previous use time is reset to zero, and the control device 70 resumes recording the use time of the soda water machine. Preferably, the duration of use is from 15 days to 30 days.
When the time of use reaches the preset time, the control device 70 sends out a drainage instruction to control the drainage valve on the drainage pipe to be opened so as to realize the drainage of the water storage tank 11, thereby replacing the water in the water storage tank 11 and preventing the water in the water storage tank 11 from growing a large amount of bacteria due to long-time standing.
Typically, the soda machine further comprises a normal temperature module and a hot water module; the hot water module includes a hot water tank 31. The water inlet side of the filter module 50 is communicated with an external water source, and the water outlet side of the filter module 50 is communicated with the water inlet side of the normal temperature module. The water outlet side of the normal temperature module forms a purified water source, and is respectively connected with the water inlet end of the cold water pipe 13 and the hot water module (specifically connected with the hot water tank), meanwhile, the water outlet side of the normal temperature module is also communicated with the outside through a normal temperature water pipe so as to provide normal temperature water for a user, and a normal temperature water valve 41 is arranged on the normal temperature water pipe. The water outlet end of the cold water pipe 13 is connected with the water inlet hole of the soda water tank 21 to prepare soda water, the water outlet end of the cold water pipe 13 is also connected with the outside through a cold water outlet pipe to provide cold water for a user, and the cold water outlet pipe is provided with a cold water valve 17. The water outlet hole of the soda water tank 21 is provided with a soda water pipe which is communicated with the outside to provide soda water for users, and the soda water pipe is provided with a soda water valve 22.
The water storage tank 11 has a water inlet communicating with the water outlet side of the filter module 50. In this way, the water flowing into the water storage tank 11 is the purified water filtered by the filtering module 50, so that the bacteria growth and the deposition of impurities in the water storage tank 11 can be reduced.
In one embodiment, the hot water tank 31 has a normal temperature water inlet communicating with a clean water source and a hot water outlet communicating with the outside. In a specific embodiment, the water outlet side of the normal temperature module forms a clean water source, and the normal temperature water inlet is communicated with the water outlet side of the normal temperature module. A heating element is disposed in the hot water tank 31 and is electrically connected to the control device 70. The control device 70 is further configured to control the heating element to stop working and control the hot water tank 31 to feed water when receiving a start-up command; the control device 70 is further configured to control the hot water tank 31 to stop water inflow when receiving the water full signal of the hot water tank 31.
Preferably, the hot water tank 31 in the embodiment of the present invention is a pressure tank, a hot water valve 32 is disposed at a normal temperature water inlet of the hot water tank 31, and the hot water valve 32 is controlled to be opened to enable the hot water to flow into the hot water tank 31, so that the pressure in the hot water tank 31 is increased, and the original water in the hot water tank 31 is extruded from a hot water outlet of the hot water tank 31. By controlling the hot water valve 32 to close, the inflow of the hot water into the hot water tank 31 is prevented, and the water in the hot water tank 31 cannot flow out when the pressure in the hot water tank 31 is low. In this embodiment, the control device 70 specifically controls the hot water valve 32 to open to enable the hot water tank 31 to feed water, and controls the hot water valve 32 to close to enable the hot water tank 31 to stop feeding water.
In the above, when the water outlet of the hot water tank 31 is detected, the water full signal of the hot water tank 31 is received. Specifically, a pressure sensor for detecting the pressure at the hot water outlet is disposed at the hot water outlet of the hot water tank 31, and when the pressure detected by the pressure sensor is greater than the preset pressure, it indicates that water in the hot water tank 31 flows out, and the control device 70 receives a water full signal of the hot water tank 31. Of course, in other embodiments, the water full signal of the hot water tank 31 is considered to be received when it is detected that the water level in the hot water tank 31 reaches a high level value. Specifically, a water level detecting member 60 for detecting the water level of the hot water tank 31 is provided in the hot water tank 31, and when the water level in the hot water tank 31 reaches a high water level value, the control device 70 is regarded as receiving a water full signal of the hot water tank 31.
In the embodiment of the present invention, when a start-up command is received, the control device 70 controls the heating element to stop working, so that the phenomenon of dry heating of the heating element due to insufficient water in the hot water tank 31 can be avoided, and the safety performance can be improved. Meanwhile, when a start-up instruction is received, the hot water tank 31 is also controlled to feed water so as to ensure that the hot water tank 31 can be in a full water state. In this way, by detecting whether the hot water tank 31 is full when the soda water machine is used for the first time, it is possible to ensure that the hot water tank 31 is in a full state when heated, and dry heating is avoided.
Further, the control device 70 is further configured to control the hot water tank 31 to stop water inflow when a heating command is received and a water full signal of the hot water tank 31 is received; the control device 70 is further configured to control the heating element to stop working and control the hot water tank 31 to supply water when a heating command is received and a water full signal of the hot water tank 31 is not received.
In this embodiment, when the heating command is received, it is determined whether the control device 70 receives the water full signal of the hot water tank 31, so that dry heating of the hot water tank 31 due to less water can be avoided, and thus the use safety of the soda water machine can be improved. When the water full signal of the hot water tank 31 is received, the control device 70 controls the heating member to operate so as to heat the water of the hot water tank 31. In addition, when the water in the hot water tank 31 is heated to a preset temperature, and when the control device 70 receives a hot water use command, the control device 70 controls the hot water valve 32 to be opened so that the hot water flows out. And when the water full signal of the hot water tank 31 is not received, the control device 70 controls the heating element to stop working, so as to avoid dry heating. Meanwhile, the control device 70 further controls the water tank 31 to be filled until the control device 70 receives the water full signal of the water tank 31, and then controls the water tank 31 to stop water filling and controls the heating element to work.
The control device 70 is also used for controlling the water outlet of the normal temperature module when receiving a normal temperature water use instruction; the control device 70 is further used for controlling the water outlet of the cold water module when receiving a cold water use instruction; the control device 70 is further used for controlling the water outlet of the hot water module when receiving a hot water use instruction; the control device 70 is also used for controlling the soda water module to discharge water when receiving a soda water use command.
In the above description, the control device 70 controls the normal temperature module to output water by controlling the normal temperature water valve 41 to be opened, so as to provide the normal temperature water for the user; when receiving the normal temperature water stop command, the control device 70 controls the normal temperature water valve 41 to be closed. The control device 70 controls the water outlet of the cold water module to provide cold water for a user by controlling the cold water valve 17 to open; when receiving a cold water stop command, the control device 70 controls the cold water valve 17 to be closed.

The control device 70 controls the soda module to discharge water by controlling the soda valve 22 to open specifically so as to provide soda water for a user; when receiving the soda water stop command, the control device 70 controls the soda water valve 22 to be closed.
Preferably, a water level probe is further provided in the soda tank 21 for detecting the water level of the soda tank 21, and the control device 70 controls the soda tank 21 to feed water when the water level in the soda tank 21 is lower than a lower limit value of the water level; when the water level in the soda tank 21 reaches the upper limit value of the water level, the control device 70 controls the soda tank 21 to stop water intake.
In the embodiment of the present invention, the evaporator 12 is spaced from the cold water pipe 13, so that it is possible to avoid freezing of the purified water in the cold water pipe 13 due to too low temperature caused by too close distance between the cold water pipe 13 and the evaporator 12. In order to make the amount of cold water produced at one time more, i.e. to lengthen the length of the cold water pipe 13, the cold water pipe 13 is arranged in a roundabout or annular shape. Similarly, to increase the heat exchange area, the evaporator 12 is also disposed in a roundabout manner or in a ring shape. Preferably, in an embodiment, the cold water pipe 13 and the evaporator 12 are respectively disposed along the peripheral wall of the water storage tank 11 in a ring shape. Specifically, the cold water pipe 13 includes a plurality of heat exchange ring parts stacked and connected in sequence from top to bottom, and the evaporator 12 includes a plurality of evaporation ring parts stacked and connected in sequence from top to bottom. The heat exchange ring part and the evaporation ring part are respectively preferably square, and of course, the heat exchange ring part and the evaporation ring part can also be respectively round or polygonal. The evaporator 12 is located at the periphery of the cold water pipe 13, so that the cold water pipe 13 is surrounded by the evaporator 12, and the cold energy of the evaporator 12 is concentrated toward the middle, so that the refrigerating effect of the cold water pipe 13 is better.
In the above embodiment, the soda tank 21 is located in the area surrounded by the cold water pipe 13. That is, in this embodiment, the cold water pipe 13 and the evaporator 12 are respectively disposed around the soda water tank 21 so that the soda water in the soda water tank 21 can be further cooled by the evaporator 12, thereby improving the cooling effect of the soda water. Meanwhile, if the soda water tank 21 is located between the cold water pipe 13 and the evaporator 12, the soda water tank 21 exchanges heat with the evaporator 12 before the cold water pipe 13, so that the cold water pipe 13 obtains less cold energy at a portion adjacent to the soda water tank 21 and obtains more cold energy at a portion far from the soda water tank 21, and therefore, the heat exchange conditions of each position of the cold water pipe 13 and the evaporator 12 are inconsistent, resulting in uneven temperature of each position of the cold water pipe 13. In the embodiment of the present invention, the soda tank 21 is located in the area surrounded by the cold water pipe 13, so as to avoid the occurrence of the above phenomenon, and thus ensure the uniformity of the temperature of the cold water pipe 13.
In order to further improve the uniformity of the temperature of the cold water pipe 13, a stirring member for flowing the water in the water storage tank 11 is further disposed in the water storage tank 11, and preferably, the stirring member is a submersible pump 14. Of course, the stirring piece can also be a fan blade. In this embodiment, the water in the water storage tank 11 can be stirred by controlling the operation of the submersible pump 14, so that the water in each position is mixed, and the temperature of the water in each position is more uniform, that is, the cold amount exchanged between the cold water pipe 13 and the water is more consistent.
In order to avoid the loss of the cooling capacity in the water storage tank 11, an insulation layer 15 is arranged outside the water storage tank 11. The heat-insulating layer 15 is a heat-insulating sponge or foam, etc. Preferably, the heat-insulating layer 15 is disposed around the peripheral wall of the water tank 11 and covers the peripheral wall of the water tank 11.
Since the soda water tank 21 is filled with a large amount of high-pressure carbon dioxide gas, the pressure in the soda water tank 21 is relatively high, and the pressure of the cold water in the cold water pipe 13 needs to be set relatively high in order to make the cold water in the cold water pipe 13 smoothly flow into the soda water tank 21. In one embodiment, a booster pump 23 is disposed on a communication line between the soda tank 21 and the cold water pipe 13. The flow speed of the purified water in the cold water pipe 13 is low in the form of refrigerating before pressurizing, so that the heat exchange time of the purified water in the cold water pipe 13 and the heat transfer medium is prolonged, the purified water can be subjected to full heat exchange, and the refrigerating effect of the purified water is effectively improved. Of course, in other embodiments, the booster pump 23 may also be disposed on the communication pipeline between the cold water pipe 13 and the filtering module 50, so as to implement the first booster and then refrigeration. A water pump 24 is further provided in the communication line between the soda tank 21 and the cold water pipe 13.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
