Description

TECHNICAL FIELD

[0001] The utility model relates to a water treatment equipment, especially a soda water dispenser. BACKGROUND

[0002] After using for many times, some dirt, impurities and the like may be attached in the waterway, valve and carbonization tank of the soda water machine, thereby causing the water quality to be poor, affecting the taste of the output soda water, and even causing damage to the health of the user. At present, most of the soda water machines on the market are in a manual cleaning mode, and most of them need to be disassembled and cleaned by professional personnel of the manufacturer. On the one hand, the professional personnel of the manufacturer need to make an appointment and pay for the on-site service, and on the other hand, frequent disassembly will reduce the service life of the soda water machine, thereby causing poor user experience. On the other hand, the residual ice water or soda water in the soda machine can breed bacteria and needs to be cleaned and disinfected regularly.

[0003] The comparative document "soda water machine, 201710384089.X" discloses that a cleaning waterway is arranged at the water outlet of the soda water module, the other end of the cleaning waterway is connected to the water inlet end of the water outlet module, and a first on-off valve is further arranged on the cleaning waterway. When the waterways in the soda water machine need to be cleaned, the first on-off valve is opened, so that the soda water in the soda water module flows into the water outlet module through the cleaning waterway. The soda water can chemically react with the dirt to dissolve or soften the dirt in the waterway, thereby achieving good cleaning effect on the water outlet module, avoiding the dirt from adhering to the water outlet module to pollute the water body, and improving the purification effect of the soda water machine. However, this cleaning method belongs to cleaning by using flowing water, and uses the chemical reaction between soda water and dirt, which can only dissolve the dirt and cannot disinfect and sterilize.

[0028] Reference Figures 1-7 The embodiment provides a soda water dispenser, which comprises a filter element, an ice water tank, a soda cavity, a CO2 gas cylinder, and can realize three functions of pure water, ice water and soda water.

[0029] Specifically, the water inlet end of the filter element is connected to raw water, and the water outlet end is connected to the water outlet device, that is, the faucet, through the pressure reducing valve and the water inlet valve, so that the pure water outlet is realized.And the water outlet end of the pressure reducing valve is also connected to the ice water tank through the ice water replenishing valve, so that the liquid in the ice water tank can be replenished.The ice water tank is provided with a high liquid level sensor and a low liquid level sensor, so that the liquid level in the ice water tank can be detected, so that the ice water replenishing valve is opened to replenish water when the liquid level is low, and the ice water replenishing valve is closed to stop replenishing water when the liquid level is high.

[0030] A refrigeration system is arranged in the ice water tank to cool the pure water in the ice water tank.The refrigeration system adopts a compressor refrigerant cooling system (including a compressor, a fan, a coil pipe and a coil pipe NTC and an environment NTC), and the refrigeration coil of the refrigeration system is arranged between the ice water tank and the soda cavity and surrounds the ice water tank.The refrigeration coil cools the ice water tank, and the soda cavity is immersed in the ice water tank.The refrigeration temperature in the soda cavity is lower in the tank-in-tank refrigeration mode, the lower the temperature, the easier the CO2 dissolves in water, and the higher the concentration of the soda water formed, and the better the taste.The refrigeration system belongs to the prior art and is widely used in refrigerators and freezers, and the embodiment does not describe and expand it.

[0031] To realize the ice water outlet, a booster pump is also needed, the water inlet end of the booster pump is connected to the ice water tank, and the water outlet end is connected to the water outlet device through the ice water outlet valve, so that the ice water outlet is realized.And the water outlet end of the booster pump is also connected to the soda cavity through the first one-way valve, so that the ice water in the ice water tank can be sent to the water outlet device or the soda cavity through the booster pump to mix with carbon dioxide to form soda water.Similarly, the high liquid level sensor and the low liquid level sensor are also arranged in the soda cavity, so that the liquid level in the soda cavity can be detected, so that the booster pump is opened to replenish water when the liquid level is low, and the booster pump is closed to stop replenishing water when the liquid level is high.

[0032] The CO2 cylinder is connected to the soda chamber through a gas pressure limiting valve, so that the ice water in the soda chamber is filled with CO2 to form soda water. The gas pressure limiting valve limits the gas flow from the CO2 cylinder to a certain pressure range, avoiding the risk of pipeline explosion due to excessive pipeline pressure. To form soda water, the soda chamber is also connected to the water outlet device through a soda valve. In this embodiment, a pressure switch is also provided at the gas outlet end of the gas pressure limiting valve, and the pressure switch is connected to the soda chamber through a one-way valve in the gas outlet pipeline. A pressure relief valve is also provided in the soda chamber and the ice water tank. When the pressure in the soda chamber exceeds a certain threshold, the pressure relief valve can be used to release pressure to prevent the soda chamber from exploding due to excessive pressure. In this embodiment, the threshold of the pressure relief valve is set to 11 bar. Since the pressure switch is connected to the soda chamber through a one-way valve in the gas outlet pipeline, the pressure switch detects the pressure of the gas in the pipeline and cannot detect the pressure in the soda chamber. That is, the pressure switch can detect the pressure of the carbon dioxide gas coming out of the CO2 cylinder. When the pressure switch detects a very low carbon dioxide gas pressure, the gas cylinder is in a state of no or almost no carbon dioxide gas. Then the pressure switch sends a signal to the controller, and the controller sends a signal to remind that the gas cylinder needs to be replaced.

[0033] Through the above settings, the water, soda water and ice water can be discharged. Since the ice water tank, soda chamber and various pipelines will inevitably breed bacteria due to residual water after long-term use, they need to be cleaned and disinfected.

[0034] Therefore, the embodiment also includes a circulating electrolysis device, which includes a water pump 1, a salt adding box 2 and an electrolytic water module 3. The water inlet end of the water pump 1 is connected to the ice water tank, and the water outlet end is connected to the ice water tank through the salt adding box 2 and the electrolytic water module 3. The order of the water pump 1, the salt adding box 2 and the electrolytic water module 3 can also be changed. For example, the water pump 1 is placed after the electrolytic water module 3. The water pumped out by the water pump first passes through the salt adding box 2 and the electrolytic water module 3 to form electrolytic water, and then is pumped into the ice water tank by the water pump.

[0035] In this way, ice water in the ice water tank can be pumped out by the water pump 1, and a certain amount of salt can be added to the pumped water through the salt adding box 2. After passing through the electrolytic water module 3, electrolytic water is formed. After the electrolytic water is delivered to the ice water tank, a certain concentration of electrolytic water is mixed in the ice water tank. Then, the process of circulating electrolysis can be repeated to continuously increase the concentration of electrolytic water in the ice water tank. When the concentration of electrolytic water in the ice water tank is high, the process of circulating electrolysis can be stopped. At this time, the electrolytic water in the ice water tank can be pumped into the soda chamber through the booster pump, and the residual water in the soda chamber can be discharged, so that the soda chamber is disinfected by using electrolytic water. When the soda chamber is filled with electrolytic water, the electrolytic water added subsequently can enter the water outlet pipeline to disinfect and clean the subsequent pipeline. After the electrolytic water in the ice water tank is pumped into the soda chamber, the disinfection and cleaning program of the soda chamber is ended. At this time, the ice water tank is recharged with filtered water, and the process of circulating electrolysis is repeated again. After a period of standing, the ice water tank can be disinfected and cleaned by using electrolytic water. Compared with the flowing water overflow disinfection, the above-mentioned method can save water.

[0036] In addition, in the embodiment, the water pump 1 is connected to the ice water tank at a position higher than the low liquid level sensor. In this way, after the disinfection and cleaning are completed, since the water in the ice water tank is at a low liquid level, the water pump 1 can pump out the air in the ice water tank and discharge the water remaining in the circulating electrolysis equipment, so that when the salt adding box in the circulating electrolysis equipment is opened next time, the water in the pipeline of the circulating electrolysis equipment will not enter the salt bin in the salt adding box. In addition, the water in the pipeline is dead water, which is easy to breed bacteria if not discharged.

[0037] In order to facilitate the user to supplement the salt in the salt adding box 2, the shell of the soda water dispenser is provided with a space opening corresponding to the salt adding box 2 for pulling out the salt adding box 2. The salt adding box 2 is provided with a locking and ejecting mechanism, which can eject the salt adding box 2 from the space opening after being pressed once, and can be retracted after being pressed again. Such a mechanism is a prior art and is widely used in home installations.

[0038] When the salt adding box 2 is ejected, the part of the shell exposed by the salt adding box 2 is provided with a salt adding opening 21 and a sealing plug 22 for sealing the salt adding opening 21. The user can conveniently add salt through the salt adding opening 21, and can also conveniently seal the salt adding opening 21 by using the sealing plug 22.

[0039] The above-mentioned is only a preferred specific embodiment of the present application, and does not limit the patent range of the present application. Any equivalent transformation made by using the content of the present application is within the protection range of the present application.
