The invention provides a soda water machine which can be used for preparing soda water. Specifically, as shown in fig. 1, the soda water machine comprises a cold water tank 11, a soda water tank 12, a first evaporator 13, a second evaporator 14 and the like, wherein the water outlet of the cold water tank 1 is respectively communicated with the water end of a user and the soda water tank 12, one part of water in the cold water tank 11 is used for being directly drunk by the user, and the other part of water flows into the soda water tank 12 for making soda water. A cold water valve 15 is arranged on the communicating pipeline between the cold water tank 11 and the user water end, and a soda water valve 16 is arranged on the communicating pipeline between the soda water tank 12 and the user water end. The first evaporator 13 is provided in the cold water tank 11 for refrigerating water in the cold water tank 11, the second evaporator 14 is provided in the soda water tank 12 for refrigerating water in the soda water tank 12, and the first evaporator 13 and the second evaporator 14 are provided in series.
Based on the soda water machine, the invention provides a control method of the soda water machine, please refer to fig. 2, the control method comprises the following steps:
step S10, detecting the water temperature in the soda water tank through a temperature sensor arranged in the soda water tank when an opening signal of the cold water valve is received;
and step S20, when the water temperature in the soda water tank is lower than a first preset water temperature, the controller controls the soda water valve to be opened and controls the cold water tank to feed water.
In the embodiment of the present invention, since the first evaporator 13 is provided on the cold water tank 11, the first evaporator 13 cools the water in the cold water tank 11, and the water in the soda water tank 12 is provided by the cold water tank 11, the water flowing into the soda water tank 12 is relatively cool. Meanwhile, the second evaporator 14 further refrigerates the water in the soda tank 12, so that the temperature of the water in the soda tank 12 is far lower than that of the water in the cold water tank 11, and the taste of the prepared soda water is better. However, if the soda water machine is continuously in a cold water use state, that is, the user is continuously using cold water, the first evaporator 13 and the second evaporator 14 are always operated, and since the soda water machine is not in a soda water use state, water in the soda water tank 12 is not discharged, so that the water in the soda water tank 12 is continuously cooled, resulting in a low water temperature of the water in the soda water tank 12. When the temperature sensor in the soda water tank 12 detects that the water temperature in the soda water tank 12 is lower than the first preset water temperature, the controller controls the soda water valve 16 to open, so that the water with the lower water temperature in the soda water tank 12 is discharged, and at the same time, since the cold water valve 15 is open, the water received by the user at this time is the mixed water of soda water and cold water. In addition, the controller also controls the cold water tank 11 to feed water, normal temperature water with higher water temperature is replenished in the cold water tank 11, and the normal temperature water flows to the soda water tank 12 through the cold water tank, so that the water temperature in the soda water tank 12 is increased, and the freezing caused by the too low water temperature in the soda water tank 12 can be avoided.
In this embodiment, the controller controls the water inlet of the cold water tank 11, specifically, the controller controls the water inlet valve of the water inlet of the cold water tank 11 to be opened, so that the cold water tank 11 is connected with the water source.
Specifically, in this embodiment, when the water temperature in the soda water tank is lower than the first preset water temperature, the controller may specifically control the soda water valve to open:
and when the water temperature in the soda water tank is lower than a first preset water temperature, the controller controls the soda water valve to be opened intermittently.
Since the soda machine is now in cold water use, the user wishes to obtain cold water, so to reduce the impact on the user, the controller controls the soda valve 16 to intermittently open so that the soda water is intermittent, reducing the amount of soda mixed into the cold water; at the same time, the controller controls the cold water valve 15 to be continuously opened so that cold water is always discharged, and the amount of cold water is increased, so that the concentration of soda water can be greatly reduced.
In other embodiments of the present invention, when the water temperature in the soda water tank is lower than a first preset water temperature, the controller may further specifically control the opening of the soda water valve and the cold water valve to:
and when the water temperature in the soda water tank is lower than a first preset water temperature, the controller controls the soda water valve to be continuously opened.
Further, the control method of the soda water machine further comprises the following steps:
and step S30, when the water temperature in the soda water tank is lower than a first preset water temperature, the controller also controls a compressor connected with the first evaporator to stop working.
In the embodiment of the present invention, the first evaporator 13 and the second evaporator 14 may be specifically configured in series, so that when the compressor is started, the refrigerant flows in the first evaporator 13 and the second evaporator 14, that is, the first evaporator 13 and the second evaporator 14 operate simultaneously. In this embodiment, when the water temperature in the soda tank 12 is lower than the first preset water temperature, the controller also controls the compressor 26 connected to the first evaporator 14 to stop working, so that the first evaporator 13 and the second evaporator 14 stop cooling, thereby avoiding freezing due to too low water temperature in the soda tank 12.
Further, the control method of the soda water machine further comprises the following steps:
and step S40, when the water temperature in the soda water tank is lower than a first preset water temperature, the controller also controls the air inlet of the soda water tank to stop air intake.
In the embodiment of the invention, when the soda water machine is in a cold water use state, the original purpose of a user is to obtain cold water, so considering that part of users only need cold water, the controller can close the air inlet of the soda water tank 12 when the soda water machine is used for preparing cold water so as to avoid that carbon dioxide gas is filled into the soda water tank 12, and the water flowing out of the soda water tank 12 is cold water or soda water with extremely low concentration.
Referring to fig. 3 in combination, in the embodiment of the present invention, the step S20 may specifically be:
step S21, when the water temperature in the soda water tank is lower than a first preset water temperature, the controller controls the soda water valve to be opened;
and step S22, when the closing signals of the cold water valve and the soda water valve are received, the controller controls the cold water tank to feed water.
Specifically, while the soda water valve 16 is opened, the cold water valve 15 is also opened, so that the user desires the water with a lower temperature, and if the cold water tank 11 is controlled to be fed while discharging the cold water, the cold water tank 11 is newly fed with the normal temperature water with a higher temperature, so that the temperature of the cold water flowing out of the cold water tank 11 is higher, and it is difficult to satisfy the user's demand. Therefore, in the embodiment of the present invention, the cold water tank 11 is not fed while the cold water valve 15 and the soda water valve 16 are opened, and only after the cold water valve 15 and the soda water valve 16 are closed, the cold water tank 11 is fed, so as to avoid influencing the outlet water temperature.
Further, the control method of the soda water machine further comprises the following steps:
and S50, after the soda water valve is opened for a preset time, the controller controls the soda water valve to be closed.
In the embodiment of the present invention, the opening of the soda water valve 16 may be controlled according to the opening time of the soda water valve 16, and when the opening time of the soda water valve 16 reaches the preset time, the controller determines that the water temperature in the soda water tank 12 is higher, and then the controller controls the soda water valve 16 to be closed. In this embodiment, the preset time period may be set in advance according to the water outlet flow rate of soda water or the like.
In addition, in other embodiments of the present invention, the step S50 may be replaced by:
and step S60, when the water temperature in the soda water tank is higher than a fourth preset water temperature, the controller controls the soda water valve to be closed.
In the embodiment of the present invention, if the cold water valve 15 is opened and water newly added in the cold water tank 11 flows into the soda water tank 12 when the cold water tank 11 is in water, the water temperature of the water in the soda water tank 12 gradually increases due to the fact that the water temperature in the cold water tank 11 flows into the soda water tank 12 with higher water temperature, so that when the water temperature in the soda water tank 12 is higher than the fourth preset water temperature, the controller controls the soda water valve 16 to be closed so as to avoid continuous flow of soda water.
Referring to fig. 4 in combination, the control method of the soda water machine further includes the following steps:
step S70, detecting the water temperature in the cold water tank through a temperature sensor arranged in the cold water tank;
and S80, when the water temperature in the cold water tank is higher than a second preset water temperature, the controller controls the compressor to start.
And step S90, when the water temperature in the cold water tank is lower than a third preset water temperature, the controller controls the compressor to stop working.
In the embodiment of the invention, when the water temperature in the cold water tank 11 is higher than the second preset water temperature, the water temperature in the cold water tank 11 is too high, so that the requirement of a user on the cold water temperature is difficult to meet, and the controller controls the compressor to restart so as to perform new refrigeration again. When the temperature of the water in the cold water tank 11 is lower than the third preset water temperature, it means that the temperature in the cold water tank 11 has reached the user's demand, so in order to save power and to avoid the water temperature in the soda water tank 12 being too low due to continuous cooling of the compressor, the controller controls the compressor to stop working.
The invention also provides a soda water machine which can be used for preparing soda water. Specifically, as shown in fig. 1, the soda water machine includes a cold water tank 11, a soda water tank 12, a first evaporator 13, a second evaporator 14, and the like.
The cold water tank 11 may have a cylindrical shape, a square shape, or the like, and of course, the shape of the cold water tank 11 is not limited in the present invention. The cold water tank 11 is provided with a first water inlet and a first water outlet, and the first water inlet is communicated with a water source so that pure water flows into the cold water tank 11; the first water outlet is communicated with a water end for users to provide cold water for users, which is prepared by the cold water tank 11. In general, a cold water valve 15 is arranged on a cold water pipe communicated with the first water outlet and the user water end, and the cold water valve 15 controls the on-off of the cold water pipe.
The soda tank 12 may be cylindrical, square, or the like, and of course, the shape of the soda tank 12 is not limited in the present invention. The soda tank 12 has a second water inlet communicating with the first water outlet of the cold water tank 11, a second water outlet communicating with the air source, and an air inlet communicating with the user water end to provide the user with soda water produced through the soda tank 12. In general, a soda water valve 16 is arranged on the soda water pipe communicated with the second water outlet and the user water end, and the soda water valve 16 controls the on-off of the soda water pipe. In order to prevent water from flowing back into the cold water tank 11 due to excessive pressure in the soda water tank 12, a first check valve 17 is provided in a communication path between the soda water tank 12 and the cold water tank 11, and the first check valve 17 is connected in a water outlet direction of the cold water tank 11.
In order to avoid that the air pressure in the soda water tank 12 is too high and the safety performance is affected, a pressure release valve 41 is also arranged on the soda water tank 12. For detecting the water level in the soda water tank 12, a water level detecting member 18 is also provided in the soda water tank 12. Specifically, the water level detecting member 18 is a water level probe, and the number of the water level probes is two, wherein one water level probe extends into the lower end of the soda water tank 12 and is used for detecting the low water level in the soda water tank 12, and when the water level in the soda water tank 12 drops to the low water level, the controller controls the water inlet of the water inlet hole; the other water level probe extends into the upper end of the soda water tank 12 and is used for detecting the high water level of the soda water tank 12, and when the water level in the soda water tank 12 rises to the high water level, the controller controls the water inlet hole to stop water inlet.
In this embodiment, the air source communicated with the soda water tank 12 can be an external air source or a built-in air source of the soda water machine. For example, in one embodiment, the soda machine further includes a carbon dioxide gas cylinder 19, the carbon dioxide gas cylinder 19 for containing carbon dioxide gas. Since the carbon dioxide gas in the carbon dioxide gas cylinder 19 is usually a high-pressure gas, it is generally necessary to depressurize the high-pressure gas and then flow the depressurized gas into the soda water tank 12, and thus the first pressure reducing valve 21 is provided in the gas pipe. In order to prevent the gas in the soda water tank 12 from flowing back into the carbon dioxide gas bottle 19, a second one-way valve 22 is further arranged on the gas pipe communicating the soda water tank 12 and the carbon dioxide gas bottle 19, and the conducting direction of the second one-way valve 22 is the direction from the carbon dioxide gas bottle 19 to the soda water tank 12. In the invention, since the carbon dioxide gas in the carbon dioxide gas bottle 19 is continuously filled into the soda water tank 12 to prepare soda water, and the carbon dioxide gas in the carbon dioxide gas bottle 19 is gradually reduced, a pressure switch 23 is arranged on the air pipe, the pressure switch 23 is used for detecting the air pressure in the carbon dioxide gas bottle 19, and when the air pressure in the carbon dioxide gas bottle 19 is too low, for example, when the air pressure is low to a low pressure threshold value, the pressure switch 23 is conducted so as to prompt a user to replace the carbon dioxide gas bottle 19 in time. In another embodiment, the soda tank 12 is communicated with the external carbon dioxide tank 24, and a third check valve 25 is provided on the communicating pipeline of the soda tank 12 and the external carbon dioxide tank 24.
The first evaporator 13 is provided in the cold water tank 11, and cools water in the cold water tank 11. Specifically, the first evaporator 13 is wound around the outer peripheral wall of the cold water tank 11 and is attached to the cold water tank 11 to cool the cold water tank 11, and since the first evaporator 13 is not in contact with the water in the cold water tank 11, the first evaporator 13 can be prevented from polluting the water in the cold water tank 11 when leakage occurs. In addition, the first evaporator 13 may be located in the cold water tank 11.
The second evaporator 14 is provided in the soda tank 12 and is used for refrigerating water in the soda tank 12. Specifically, the second evaporator 14 is provided around the outer peripheral wall of the soda tank 12. The second evaporator 14 is in direct contact with the outer peripheral wall of the soda tank 12 to cool the soda tank 12. Since the second evaporator 14 is not in contact with the water in the soda tank 12, it is possible to avoid contamination of the water in the soda tank 12 by the second evaporator 14 when leakage occurs. In addition, the second evaporator 14 may also be located within the soda tank 12.
In this embodiment, the first evaporator 13 and the second evaporator 14 are arranged in series, which means that the pipelines of the first evaporator 13 and the second evaporator 14 are arranged in series, so that when a user takes cold water, the first evaporator 13 works, and the first evaporator 13 refrigerates the cold water tank 11 to provide cold water for the user; at the same time, the second evaporator 14 also operates, and the second evaporator 14 cools the soda water tank 12 to quickly supply soda water when a user desires. When a user takes soda water, the first evaporator 13 and the second evaporator 14 work simultaneously, water in the cold water tank 11 flows into the soda water tank 12 after being refrigerated by the first evaporator 13, and the second evaporator 14 further refrigerates the soda water in the soda water tank 12 so as to ensure the taste of the soda water.
Further, the soda machine further includes a compressor 26, a condenser 27, a throttle device 28, and the like, and the first evaporator 13 is connected to the compressor 26. Specifically, the compressor 26, the condenser 27, and the throttle device 28, the first evaporator 13, and the second evaporator 14 are sequentially connected to form a closed loop for the refrigerant to circulate.
Further, a first temperature sensor 29 is provided in the cold water tank 11, and the first temperature sensor 29 is used for detecting the water temperature in the cold water tank 11, so that the water temperature of the cold water in the cold water tank 11 meets the user requirement. A second temperature sensor 31 is provided in the soda tank 12 for detecting the temperature of the water in the soda tank 12 so that the temperature of the soda water in the soda tank 12 meets the user's requirements. In this embodiment, the controller of the soda water machine is electrically connected to the first temperature sensor 29, the second temperature sensor 31, the soda water valve 16, the cold water valve 15, and the compressor 26, respectively.
Specifically, when the soda machine is in a cold water use state (i.e., the cold water valve 15 is opened), and when the temperature of the water in the soda water tank 12 is lower than a first preset value, the controller controls the soda water valve 16 to open so that the soda machine simultaneously flows out the soda water and the cold water, and the water received by the user is mixed water of the soda water and the cold water. Meanwhile, the controller also controls the cold water tank 11 to feed water, normal-temperature water with higher water temperature is replenished in the cold water tank 11, and the normal-temperature water flows to the soda water tank 12 through the cold water tank, so that the water temperature in the soda water tank 12 is increased, and the freezing caused by the too low water temperature in the soda water tank 12 can be avoided.
Specifically, in this embodiment, the controller may control the soda water valve 16 to open intermittently and the cold water valve 15 to open continuously. Since the soda machine is now in cold water use, the user wishes to obtain cold water, so to reduce the impact on the user, the controller controls the soda valve 16 to intermittently open so that the soda water is intermittent, reducing the amount of soda mixed into the cold water; at the same time, the controller controls the cold water valve 15 to be continuously opened so that cold water is always discharged, and the amount of cold water is increased, so that the concentration of soda water can be greatly reduced. In other embodiments of the invention, the controller may also control the soda water valve 16 and the cold water valve 15 to be continuously opened.
Further, the controller is also configured to control the compressor 26 to stop operating when the water temperature in the soda tank 12 is below a first predetermined water temperature. The controller controls the compressor 26 to stop operating to avoid freezing due to too low a water temperature in the soda tank 12.
Further, the controller is also configured to control the intake port of the soda tank 12 to stop intake when the water temperature in the soda tank 12 is lower than the first preset water temperature. Considering that only cold water is needed by some users, the controller may close the air inlet of the soda water tank 12 when preparing cold water to avoid carbon dioxide gas from being filled into the soda water tank 12, and the water flowing out of the soda water tank 12 is cold water or soda water with extremely low concentration.
In the above, since the compressor 26 stops working and the cold water and the soda water flow out all the time and new normal temperature water is continuously replenished, so that the water temperatures in the cold water tank 11 and the soda water tank 12 are higher, when the water temperature in the soda water tank 12 is higher than the fourth preset water temperature, the water temperature in the soda water tank 12 is higher at this time, the soda water tank 12 is not frozen, and the controller controls the soda water valve 16 to be closed at this time. Additionally, in other embodiments, the length of the opening of the soda water valve 16 may also be set, and when the length of the opening of the soda water valve 16 reaches a preset length, the controller controls the compressor 26 to start and controls the soda water valve 16 to close. By the above arrangement, the phenomenon that cold water is not cooled due to the fact that the compressor 26 is not started and the soda tank 12 is frozen due to the fact that the compressor 26 is started for a long time can be avoided.
Further, the soda machine also includes a hot water tank 32, the hot water tank 32 being in communication with a water source. The hot water tank 32 has a third water inlet in communication with a water source and a hot water outlet in communication with a user water side for providing hot water to the user. The hot water tank 32 in the embodiment of the invention is a pressure type water tank, the hot water valve 33 is arranged at the third water inlet of the hot water tank 32, and the hot water valve 33 is controlled to be opened so as to enable water of a water source to flow into the hot water tank 32, and the pressure in the hot water tank 32 is increased, so that the original water in the hot water tank 32 is extruded from a hot water outlet of the hot water tank 32. By controlling the hot water valve 33 to close, the water from the water source is prevented from flowing into the hot water tank 32, and the pressure in the hot water tank 32 is low, so that the water in the hot water tank 32 cannot flow out.
A drain outlet is provided at the bottom of the hot water tank 32, and a drain pipe 33a is connected to the drain outlet. In this embodiment, the drain pipe 33a is directly connected to the outside of the casing of the soda water machine, and when the hot water tank 32 needs to be cleaned, the drain pipe 33a can be used for draining the water in the hot water tank 32, so that the user can clean the hot water tank 32 conveniently to avoid water accumulation in the hot water tank 32. The hot water tank 32 further has an exhaust port provided near the top end of the hot water tank 32, and an exhaust pipe 33b is provided for exhausting hot air in the hot water tank 32, thereby avoiding an excessive air pressure in the hot water tank 32.

Of course, both the cold water tank 11 and the hot water tank 32 may be connected to both the tap water and the water tank 34 to establish water source communication with one of them as desired. Specifically, in the embodiment in which the cold water tank 11 and the hot water tank 32 are simultaneously connected to the tap water and the water tank 34, the soda machine includes a water inlet pipe and two water diversion pipes, the first water inlet of the cold water tank 11 and the third water inlet of the hot water tank 32 are both connected to the water outlet end of the water inlet pipe, the two water diversion pipes are both communicated with the water inlet end of the water inlet pipe, one of the water diversion pipes is connected to the water tank 34, and a fourth check valve 35 is provided on the water diversion pipe, and the fourth check valve 35 is used for preventing water in the water inlet pipe from flowing back to the water tank 34. The other water diversion pipe is communicated with a tap water source, and a second pressure reducing valve 36, a fourth electromagnetic valve 42 and a pre-filter element 43 are arranged on the other water diversion pipe. A water purifying device is arranged on the communicating pipe of the cold water tank 11 and the water source, and the water purifying device can be arranged on the water inlet pipe or the water dividing pipe. For example, in the present embodiment, the water purifying apparatus includes a membrane filter 37 provided on the water inlet pipe and a pre-filter 43 provided on the water diversion pipe, and the water filtered through the membrane filter 37 is pure water which can flow into the cold water tank 11 and the hot water tank 32, respectively.

Specifically, the booster pump 38 is disposed on the water inlet pipe, preferably, the booster pump 38 is disposed on the water inlet side of the membrane cartridge 37, so that the water pressure on the water inlet side of the membrane cartridge 37 can be increased, and the pure water outlet rate of the membrane cartridge 37 can be further increased. Of course, the booster pump 38 may also be provided on the water outlet side of the membrane cartridge 37. By providing the booster pump 38, the water pressure can be increased, and pure water can be ensured to flow into the hot water tank 32, the cold water tank 11, and the soda water tank 12.
In addition, a normal temperature water pipe is also connected to the water inlet pipe and the water outlet side of the membrane filter core 37, the normal temperature water pipe is communicated with the water end for users to provide normal temperature water for the users, and a normal temperature water valve 39 is arranged on the normal temperature water pipe to control the on-off of the normal temperature water pipe.
