Meanwhile, the refrigeration unit 2 may be in an operating state to cool the water in the first water storage unit 4, and the water in the first water storage unit 4 and the water in the second water storage unit 10 are circulated through the pressurization device 1, so that the water in the second water storage unit 10 can be cooled and finally become cold water.

And just avoid freezing of local water in the first water storage unit 4 through the above-mentioned mode of this application, realize the holistic rapid cooling of all water in the first water storage unit 4 simultaneously, do not have the poor problem of temperature layering cooling effect.

In order to better understand the functional water supply apparatus of the present application, it will be further explained and illustrated below. As shown in fig. 1, the first water storage unit 4 in the functional water supply apparatus is used to store a certain volume of water. The refrigerating unit 2 is used for refrigerating the water stored in the first water storage unit 4, so that the water can be cooled to a lower temperature to become cold water and be stored in the first water storage unit 4 all the time, for example, the lower temperature may be a preferred cold water temperature set by a user. When the functional water generating unit 3 needs to add water, the cold water or uncooled water stored in the first water storage unit 4 may be directly input into the functional water generating unit 3. The functional water generating unit 3 is for generating functional water, which may receive cold water or uncooled water supplied from the first water storage unit 4 to generate functional water, and the generated functional water may be stored in the functional water generating unit 3. When the user needs the functional water, the functional water that has been generated in the functional water generation unit 3 can be output at any time to be provided to the user. The functional water can be cold water or normal temperature water.

As shown in fig. 1, the functional water generating unit 3 may communicate with the first water storage unit 4 through a first pipe 5, and the cold water or uncooled water in the first water storage unit 4 may be transferred to the functional water generating unit 3 through the first pipe 5. The pressure increasing device 1 of the functional water supply device may be provided on the first pipe 5, an inlet of the pressure increasing device 1 may be capable of communicating with the first water storage unit 4, and an outlet of the pressure increasing device 1 may be capable of communicating with the functional water generation unit 3. Whether the cold water or the uncooled water in the first water storage unit 4 is transferred to the functional water generating unit 3 can be controlled by whether the pressurizing device 1 is operated. The functional water supply device may have a first operation state in which the pressure increasing device 1 is in an open state and water in the first water storage unit 4 flows into the functional water generation unit 3 through the pressure increasing device 1 and the first pipe 5. By this operation state, when the functional water in the functional water generating unit 3 is used up or is insufficient, the water in the first water storage unit 4 can be supplemented to the functional water generating unit 3 by the supercharging device 1, and the water in the first water storage unit 4 may be cold water after being cooled down, or may be water which is not completely cooled or uncooled water. Correspondingly, a water level detecting unit may be provided in the functional water generating unit 3 so that the functional water supplying means can judge the level of the functional water in the functional water generating unit 3 to determine whether the water in the first water storage unit 4 is replenished to the functional water generating unit 3 by the pressurizing means 1. Of course, in other alternative embodiments, the functional water generation unit 3 may have other monitoring units commonly used by those skilled in the art for detecting whether the functional water generation unit needs to be replenished with water, such as a flow sensor, a timer, etc., which are not limited herein.

As shown in fig. 3 and 4, the functional water supply device may include, as a practical matter: a second conduit 6. The second pipe 6 of the functional water supply device may be disposed between the outlet of the pressure boosting device 1 and the first water storage unit 4. The outlet of the second pipeline 6 for the supercharging device 1 is communicated with the first water storage unit 4. Whether the pressure boosting device 1 is operated or not can control whether the cold water or the uncooled water in the first water storage unit 4 flows back to the first water storage unit 4 through a part of the first pipeline 5 and the second pipeline 6. The functional water supply device may have a second operation state in which the pressurizing device is in an open state and the water in the first water storage unit 4 is returned to the first water storage unit 4 through the pressurizing device 1 and the second pipe 6. Meanwhile, the refrigerating unit 2 may be in an operating state to cool the water in the first water storage unit 4. Through the operation state, the water in the first water storage unit 4 can be pumped out by the supercharging device 1 and then flows back to the first water storage unit 4 through the second pipeline 6, the water in the first water storage unit 4 can flow circularly, so that when the refrigeration unit 2 cools the water in the first water storage unit 4 quickly, the phenomenon that the water in the first water storage unit 4 is locally easy to freeze is avoided, particularly the water in the contact part with the refrigeration unit 2, once the water in the contact part with the refrigeration unit 2 freezes, the thermal resistance between the refrigeration unit 2 and the water is increased, the heat transfer coefficient is greatly reduced, the refrigeration unit 2 cannot quickly realize the quick cooling of the water in other areas in the first water storage unit 4, and the cooling of the water in other areas in the first water storage unit 4 to a lower temperature. Through the above-mentioned mode of this application just can avoid freezing of local water in the first water storage unit 4, increase the cooling rate of the water in other regions in the first water storage unit 4, realize the holistic rapid cooling of all water in the first water storage unit 4 simultaneously, do not have the poor problem of temperature layering cooling effect. In addition, the water in the first water storage unit 4 can be cooled to a lower temperature with the same performance as the refrigeration unit 2. This is because once the water at the contact position of the refrigeration unit 2 freezes, the temperature of the outer side wall of the ice is higher than the temperature of the cold end of the refrigeration unit 2 due to certain thermal resistance of the ice, so that the temperature which can be reached by cooling the water in the first water storage unit 4 after the refrigeration unit 2 conducts the cold energy through the ice is higher than the temperature which can be reached by directly transferring the cold energy to the water in the first water storage unit 4 by the refrigeration unit 2 under the same condition so as to cool the water in the first water storage unit 4.

In one possible embodiment, in order to control the operation of the pressure boosting device 1, as shown in fig. 3, whether the water output from the outlet of the pressure boosting device 1 flows to the functional water generating unit 3 or flows back to the first water storage unit 4, the first pipeline 5 may be provided with a first on-off valve 51, and the first on-off valve 51 may be located between the outlet of the pressure boosting device 1 and the functional water generating unit 3. The second line 6 may be provided with a second open-close valve 61. When it is necessary to feed the water output from the outlet of the pressure booster 1 to the functional water generating unit 3, the first opening/closing valve 51 is opened and the second opening/closing valve 61 is closed. When it is necessary to return the water output from the outlet of the pressure increasing device 1 to the first water storage unit 4, the first on-off valve 51 is closed and the second on-off valve 61 is opened. When it is necessary to feed the water output from the outlet of the booster device 1 to the functional water generating unit 3 and return the water to the first water storage unit 4, the first on-off valve 51 is opened and the second on-off valve 61 is opened. In another possible embodiment, as shown in fig. 3, the outlet of the pressure boosting device 1 is connected to the first pipeline 5 and the second pipeline 6 which are respectively communicated with the functional water generating unit 3 through a control valve 7, and the control valve 7 can at least control the connection and disconnection between the outlet of the pressure boosting device 1 and the first water storage unit 4 and/or the connection and disconnection between the outlet of the pressure boosting device 1 and the functional water generating unit 3. By the above method, when the supercharging device 1 is controlled to operate, whether the water output from the outlet of the supercharging device 1 flows back to the first water storage unit 4 or not and/or whether the water output from the outlet of the supercharging device 1 flows to the functional water generation unit 3 or not can be controlled.

In order to prevent the water or gas in the functional water generating unit 3 from flowing backward through the first pipe 5, as shown in fig. 1, a first check valve 52 is provided on the first pipe 5 between the pressure increasing device 1 and the functional water generating unit 3, and the first check valve 52 is used to conduct the outlet of the pressure increasing device 1 to the functional water generating unit 3. The functional water generating unit 3 may be a bubble water generating unit, and the pressure inside the functional water generating unit 3 is relatively high in order to generate bubble water, and therefore, it is possible to prevent gas inside the bubble water generating unit, particularly carbon dioxide gas, from flowing back to the first water storage unit 4 or other components through the first pipe 5 to damage such components in the above manner. Since the pressure inside the functional water generating unit 3 is relatively high, the pressure resistance of the functional water generating unit 3 may be greater than that of other components.

The water inlet end of the first pipeline 5 may be communicated with the lower portion of the first water storage unit 4. When the refrigeration unit 2 cools and cools the water in the first water storage unit 4, the water with relatively low temperature in the first water storage unit 4 sinks to the lower part, and the water with relatively high temperature rises to the upper part, so that in this way, in the first operation state, the water with relatively low temperature in the lower part of the first water storage unit 4 can be preferentially output and supplied to the functional water generation unit 3. Further, the water outlet end of the second pipeline 6 is communicated with the upper part of the first water storage unit 4. In the second running state, can take out the lower water of first water storage unit 4 lower part temperature relative preferentially and carry to first water storage unit 4 upper portion, mix with the water that the temperature is higher than normal, can effectively rise the temperature of first water storage unit 4 lower part like this, reduce the possibility that freezing appears in the water of first water storage unit 4 lower part and refrigeration unit 2 direct or indirect contact, can also help the cooling of the water on first water storage unit 4 upper portion simultaneously, and then make the water in first water storage unit 4 cooling speed on the whole faster.

In a possible embodiment, the functional water supply means may include a first water storage tank 8 having an inner cavity. The first water storage tank 8 is provided with a partition part which divides the inner cavity into a first space and a second space which are independent, the first water storage unit 4 comprises the first space, and the functional water generation unit 3 comprises the second space. Furthermore, the isolation part can be made of a material with good heat conduction performance, such as metal, so that the cold energy of the water in the first water storage unit 4 can be transmitted to the functional water generation unit 3, and the cold water in the functional water generation unit 3 can be insulated to prevent the temperature of the cold water from rising. In this way, the refrigeration unit 2 only needs to directly cool the water in the first water storage unit 4.

In another possible embodiment, fig. 5 isbase:Sub>A plan view of the first water storage unit and the functional water generating unit according to the embodiment of the present invention, fig. 6 isbase:Sub>A cross-sectional view taken along linebase:Sub>A-base:Sub>A of fig. 5, and as shown in fig. 5 and 6, the functional water supply device may include: a first water storage tank 8 having an inner cavity and a second water storage tank 9 at least partially disposed in the first water storage tank 8, a space between the first water storage tank 8 and the second water storage tank 9 forms a first water storage unit 4, and the functional water generating unit 3 includes the second water storage tank 9. Further, the lateral wall of second water storage tank 9 can set up in the inner chamber of first water storage tank 8, and first water storage tank 8 can surround second water storage tank 9 like this on the circumferencial direction, and when the water of storage was cold water in first water storage unit 4, cold water can play better heat preservation effect to second water storage tank 9, prevents to input the cold water in the second water storage tank 9 from first water storage unit 4 and heaies up. The side wall of the second water storage tank 9 may be made of a material with good heat conduction performance, for example, metal, so that the pressure resistance of the second water storage tank 9 may be improved, and the heat conduction performance of the side wall may be improved, which is helpful for transferring the cold energy of the cold water stored in the first water storage unit 4 to the functional water in the second water storage tank 9.

As shown in fig. 6, the refrigeration unit 2 may include an evaporator 21, where a low-temperature refrigerant is introduced into the evaporator 21, and the low-temperature refrigerant exchanges heat with the water in the first water storage unit 4 directly or indirectly, so as to lower the temperature of the water in the first water storage unit 4 to a preferred cold water temperature set by a user. The refrigeration unit 2 may further include a compressor 22, a condenser 23, and an expander 24 connected in series, with the evaporator 21 being connected between an inlet of the compressor 22 and an outlet of the expander 24. The above components are connected together to form a refrigerant cycle line through the operation of the compressor 22, and the refrigerant is charged into the line. Further, an evaporator 21 may be provided on the first water storage unit 4 to cool the water stored in the first water storage unit 4. Specifically, the evaporator 21 may be disposed in a space inside the first water storage unit 4, so that the water stored in the first water storage unit 4 can directly contact the evaporator 21 for heat exchange, thereby contributing to the improvement of the heat exchange effect. In other alternative embodiments, the evaporator may also be disposed around the outside of the first water storage unit, and heat transfer may be performed between the evaporator and the first water storage unit.

As shown in fig. 6, it is possible that the water outlet 62 of the second pipe 6 communicating with the upper portion of the first water storage unit 4 is located near the evaporator 21. By the structure, the water output from the second pipeline 6 flows to the vicinity of the evaporator 21, and the water on the surface of the evaporator 21 can continuously flow, so that the icing phenomenon on the surface of the evaporator 21 is not easy to occur.

Further, as shown in fig. 6, the evaporator 21 may include heat exchange tubes wound in a spiral shape. For example, the overall extension direction of the spirally wound heat exchange tubes may be the same as the axis of the first water storage unit 4. When the space between first water storage tank 8 and the second water storage tank 9 forms first water storage unit 4, functional water generates unit 3 when including second water storage tank 9, it can overlap outside second water storage tank 9 to be the heliciform around the heat exchange tube of establishing, evaporimeter 21 can carry out comparatively even cooling to the water of storing in the first water storage unit 4 of second water storage tank 9 outside circumference direction like this, thereby accelerate cooling rate, and simultaneously, can also make the comparatively even heat preservation that receives of water in the functional water generates unit 3.

The inner side wall of the first water storage unit 4 is at least partially arc-shaped in the horizontal cross section. The horizontal cross section of the water outlet 62 of the second pipeline 6 communicated with the upper part of the first water storage unit 4 faces the same direction as the extending direction of the inner side wall of the first water storage unit 4 at the position of the water outlet, so that the water in the first water storage unit can flow. Under this structure, can make the rivers of export in the second pipeline 6 form certain circulation flow around the arc of the inside wall of first water storage unit 4 in the horizontal plane, the heat exchange tube that is the heliciform around establishing also can reduce relatively to water formation circulation flow's resistance, the hydroenergy on evaporimeter 21 surface can be continuous like this flows so that can produce the flow in first water storage unit 4 from the water outlet 62 water that flows, so, the heat exchange tube in different height all can be influenced, its surface is difficult for producing the phenomenon of icing. Further, because the inside wall part of first water storage unit 4 is the arc, above-mentioned flow can be the vortex flow, and the vortex flow can influence the water in more regions in first water storage unit 4 like this, and then can make near the water of all heat exchange tubes all produce the flow to further promote the cooling rate to the water in first water storage unit 4.

As a possibility, the first water storage unit 4 may be provided with a first ultraviolet germicidal lamp for sterilizing water stored in the first water storage unit 4. The first uv germicidal lamp may be an LED uv germicidal lamp, which has a smaller volume and higher luminous efficiency, and of course, in other possible embodiments, a straight tube type uv germicidal lamp or other types of uv germicidal lamps may also be used, which is not limited in this application. Because can be provided with the heat exchange tube in the first water storage unit 4, the heat exchange tube can block the ultraviolet germicidal light of first sterilamp transmission, consequently, the partial surface of heat exchange tube and the inside water of subregion of first water storage unit 4 can't be shone by ultraviolet germicidal light, and this can lead to the not enough problem of water sterilization rate in the first water storage unit 4. Further, when the first water storage tank 4 is formed in the gap between the first water storage tank 8 and the second water storage tank 9, and the functional water generating unit 3 includes the second water storage tank 9, more dead angles which cannot be irradiated by ultraviolet sterilization light can be formed in the first water storage unit 4 due to the existence of the second water storage tank 9, so that the problem that the sterilization rate of water in the first water storage unit 4 is insufficient can be caused. Because the functional water supply device can have the second running state, the water in the first water storage unit 4 is pumped out by the supercharging device 1 and then flows back to the first water storage unit 4 through the second pipeline 6, the water in the first water storage unit 4 can circularly flow, and the ultraviolet sterilization light emitted by the first ultraviolet sterilization lamp can effectively sterilize the water in all areas in the first water storage unit 4, so that the sterilization rate of the water is further improved.

As a possibility, in order to supply the water in the first water storage unit 4 and the functional water generation unit 3 to the user, as shown in fig. 1 to 4, the functional water supply device may include: a water output mechanism 12. The water output mechanism 12 may be a device of the type that can be controlled to open and close the output of a supply of water, such as a faucet or the like. The first water storage unit 4 may be communicable with the water output mechanism 12 through the first outlet water path 15. The functional water generating unit 3 can communicate with the water output mechanism 12 through the second effluent water path 16. In order to control the on/off between the first water storage unit 4 and the water output mechanism 12, a first water output control valve 151 may be disposed on the first water output waterway 15, for example, when the first water output control valve 151 is opened, the water output mechanism 12 is opened, and the cold water in the first water storage unit 4 after being cooled by the refrigeration unit 2 can be output and supplied to a user. In order to control the on/off of the functional water generating unit 3 and the water output mechanism 12, a second outlet water control valve 161 may be provided on the second outlet water channel 16, and when the second outlet water control valve 161 is opened, the water output mechanism 12 is opened, and the cold functional water in the functional water generating unit 3 can be output and supplied to the user. A relief valve 162 may also be provided in the second outlet water path 16, and the relief valve 162 may be located upstream of the second outlet control valve 161 to prevent excessive pressure in the second outlet water path 16.

As a matter of course, as shown in fig. 1 and 2, the functional water supply device may have a second water storage unit 10 therein, and the second water storage unit 10 may store a certain volume of water. A water level detecting unit for detecting an internal water level may be disposed in the second water storage unit 10, and the second water storage unit 10 may be communicated with a water source so as to supplement water to the second water storage unit 10 through the water source according to the water level detected by the water level detecting unit. The second water storage unit 10 can be in communication with the first water storage unit 4 and the outlet of the pressurizing device 1, respectively. The second water storage unit 10 may replenish the first water storage unit 4, and when the water in the first water storage unit 4 is insufficient or not full, the water in the second water storage unit 10 may be transferred to the first water storage unit 4. The height of the second water storage unit 10 may be higher than that of the first water storage unit 4, so that the water in the second water storage unit 10 is transferred into the first water storage unit 4 by using gravity. Correspondingly, a water level detecting unit for detecting the internal water level may be disposed in the first water storage unit 4, so that the functional water supply device can judge the level of water in the first water storage unit 4 to determine whether to replenish water to the first water storage unit 4 through the second water storage unit 10. In order to realize the controllability of the water supply from the second water storage unit 10 to the first water storage unit 4, the second water storage unit 10 and the first water storage unit 4 may be connected by a fourth pipeline 14, and a fifth on-off valve may be provided on the fourth pipeline 14. Of course, in other alternative embodiments, the first water storage unit 4 and the second water storage unit 10 may also have other monitoring units commonly used by those skilled in the art for detecting whether the first water storage unit 4 and the second water storage unit 10 need to be replenished, such as a flow sensor, a timer, etc., which are not limited herein.

Specifically, in one embodiment, as shown in fig. 1 and 2, the outlet of the booster device 1 may communicate with the second water storage unit 10 through a third pipeline 11. In order to better facilitate the control of whether the water output from the pressurizing device 1 is delivered to the second water storage unit 10, the third pipeline 11 may be provided with a third opening/closing valve 111. In another embodiment, the outlet of the pressure boosting device 1 is connected to the second water storage unit 10 through a third pipeline 11, the outlet of the pressure boosting device 1 can be connected to the first pipeline 5 and the third pipeline 11 through a control valve 7, and the control valve 7 can at least control the connection and disconnection between the outlet of the pressure boosting device 1 and the functional water supply device, or between the outlet of the pressure boosting device 1 and the second water storage unit 10. Further, as shown in fig. 3 and 4, the outlet of the pressure boosting device 1 may be connected to the first pipeline 5, the second pipeline 6, and the third pipeline 11 through the control valve 7, and the control valve 7 may at least control the connection/disconnection between the outlet of the pressure boosting device 1 and the first water storage unit 4, or between the outlet of the pressure boosting device 1 and the functional water supply device, or between the outlet of the pressure boosting device 1 and the second water storage unit 10.

As a possibility, the functional water supply device may also have a third operating state in which the pressure boosting device 1 is in an open state and the water in the first water storage unit 4 flows into the second water storage unit 10 via the pressure boosting device 1 and the third pipeline 11. Meanwhile, the water in the second water storage unit 10 can flow back to the first water storage unit 4, so that the water in the first water storage unit 4 and the water in the second water storage unit 10 circulate. As a practical matter, in the third operating state, the first ultraviolet germicidal lamp may be turned on, so that the water in the first water storage unit 4 and the second water storage unit 10 can be sufficiently sterilized, and the water in the corresponding pipelines can be sterilized at the same time. As a matter of course, the second water storage unit 10 may be provided with a second ultraviolet germicidal lamp for sterilizing the water stored in the second water storage unit 10, and the second ultraviolet germicidal lamp has a relatively better sterilization effect on the water stored in the second water storage unit 10 because there is no shelter in the second water storage unit 10. Under the third running state, the second ultraviolet germicidal lamp can be in the on state, so that the water in the first water storage unit 4 and the second water storage unit 10 can be well sterilized, and meanwhile, the water in the corresponding pipeline can also be sterilized.

In a third operating state, the refrigeration unit 2 may be in an operating state to cool the water in the first water storage unit 4, and the water in the first water storage unit 4 and the water in the second water storage unit 10 are circulated through the pressurization device 1, so that the water in the second water storage unit 10 can also be cooled and finally becomes cold water. When a user needs a large amount of cold water or a large amount of cold functional water, the user can switch the functional water supply device to the third running state in advance, so that the functional water supply device can cool all the water in the first water storage unit 4 and the second water storage unit 10 to the cold water with the temperature set by the user in advance, and when the user needs the cold water or the cold functional water in the later period, the functional water supply device can supply the cold water in the first water storage unit 4 to the user for use, and then can input the cold water in the second water storage unit 10 into the first water storage unit 4 and supply the cold water to the user through the first water storage unit 4, so that the effect of capacity increase of the first water storage unit 4 is achieved through phase change; or, the functional water supply device may supply the cold functional water in the functional water generation unit 3 to a user, and then input the cold water in the first water storage unit 4 into the functional water generation unit 3, and simultaneously directly generate the cold functional water through the functional water generation unit 3 to be supplied to the user, after the cold water in the first water storage unit 4 is used up, the cold water in the second water storage unit 10 may supplement the first water storage unit 4, so that the functional water generation unit 3 can finally directly generate the cold functional water to be supplied to the user, and the cold functional water in the sum of the volume of the functional water generation unit 3 and the volume of the first water storage unit 4 and the volume of the second water storage unit 10 can be directly output in a short period of time. By the mode, the water demand of cold water or cold functional water under large water intake of a user is met. Meanwhile, the water in the first water storage unit 4 is pumped into the second water storage unit 10 by the supercharging device 1, the water in the second water storage unit 10 flows back to the first water storage unit 4, and the water in the first water storage unit 4 can also flow circularly, so that the phenomenon that the water in the first water storage unit 4 is locally easy to freeze, especially the water at the contact part of the refrigeration unit 2, cannot be caused when the refrigeration unit 2 cools the water in the first water storage unit 4 quickly. Through the above-mentioned mode of this application also can avoid freezing of local water in first water storage unit 4, realize the holistic rapid cooling of all waters in first water storage unit 4 simultaneously, do not have the poor problem of temperature layering cooling effect.

In the above embodiment, as possible, as shown in fig. 1 to 4, the second water storage unit 10 may be communicable with the water output mechanism 12 through the third effluent water path 17. In order to control the on/off between the second water storage unit 10 and the water output mechanism 12, a third outlet control valve 171 may be disposed on the third outlet water path 17, for example, when the third outlet control valve 171 is opened, the water output mechanism 12 is opened, and the normal temperature water in the second water storage unit 10 can be output and supplied to the user. In the above manner, the water output mechanism 12 can supply normal-temperature water, cold water, and cold functional water to the user, respectively.

In all the above embodiments, the functional water may be water rich in some functional gas required by the user, such as hydrogen-rich water, oxygen-rich water, bubble water, etc., and is not limited in any way in this application. When the functional water is water rich in some functional gas, the functional water supply device may include: a functional gas supply unit 13 for inputting a functional gas into the functional water generation unit 3, the functional gas supply unit 13 comprising: a gas cylinder 131 capable of storing functional gas; a pressure reducing device 132; and a fourth closing valve 133, and the outlet of the gas cylinder 131 can be communicated with the functional water generating unit 3 through the pressure reducing device 132 and the fourth closing valve 133. Further, a low pressure switch 135 may be provided between the fourth closing valve 133 and the pressure reducing device 132, the low pressure switch 135 may be triggered at a low pressure, and when the gas in the gas cylinder 131 is about to be used up, the pressure value in the gas cylinder 131 is too low, the low pressure switch 135 is triggered, so that the functional water supply device gives an alarm to remind a user to replace the gas cylinder.

In this way, when the functional water generating unit 3 is required to generate functional water, the functional gas stored in the gas cylinder 131 is depressurized by the depressurizing device 132 and then replenished into the functional water generating unit 3. Especially when the functional water is bubble water, the functional water generating unit 3 includes a bubble water generating unit, the functional gas stored in the gas cylinder 131 in the functional gas supply unit 13 is carbon dioxide, and the carbon dioxide can be dissolved in cold water at a relatively large concentration in a high-pressure environment of the functional water generating unit 3, thereby generating cold bubble water for the user to use at any time.

In order to prevent the gas or water in the bubble water generating unit from flowing back to the pressure reducing device 132 and the fourth opening/closing valve 133 in the functional gas supply unit 13 under pressure to cause leakage, etc., a second check valve 134 may be provided between the outlet of the gas cylinder 131 and the functional water generating unit 3, the second check valve 134 being used to conduct the outlet of the gas cylinder 131 to the functional water generating unit 3.

Also disclosed in the present application is a control method of a functional water supply apparatus, which may include:

when the functional water supply device enters the second operation state, the refrigeration unit 2 may be turned on to cool the water in the first water storage unit 4. In a specific embodiment, the refrigeration unit 2 starts the compressor 22, and passes the compressed refrigerant through the condenser 23, the expander 24 and the evaporator 21, and the low-temperature refrigerant passing through the expander 24 exchanges heat with the water in the first water storage unit 4 through the heat exchange pipe in the evaporator 21, so as to cool the water in the first water storage unit 4.

The pressurizing device 1 is started, and water in the first water storage unit 4 flows back to the first water storage unit 4 through a part of the first pipeline 5, the pressurizing device 1 and the second pipeline 6. Through the step, the water can form backflow in the first water storage unit 4, the first pipeline 5 and the second pipeline 6 by utilizing the supercharging device 1, so that water around the heat exchange pipe in the evaporator 21 flows, the evaporator 21 cannot cause the phenomenon that water in the first water storage unit 4 is easy to freeze locally when the water in the first water storage unit 4 is cooled rapidly, particularly the water at the contact part with the evaporator 21, the cooling speed of water in other areas in the first water storage unit 4 can be increased through the process, and the rapid cooling of all water in the first water storage unit 4 integrally is realized. Since the overall temperature of the water in the first water storage unit 4 is relatively high when the refrigeration unit 2 starts to cool the water in the first water storage unit 4, even if the water near the evaporator 21 is difficult to freeze, as a practical matter, the supercharging device 1 may be turned on after the water in the first water storage unit 4 is cooled to a first preset temperature, which may be more energy-saving, and the first preset temperature may be any temperature between the normal temperature and the cold water temperature set by the user, which is not limited in this application. Of course, the first water storage unit 4 may have a temperature measurement unit for measuring the temperature of the water in the first water storage unit 4.

When the pressurizing device 1 is turned on and water in the first water storage unit 4 flows back to the first water storage unit 4 through a part of the first pipeline 5, the pressurizing device 1 and the second pipeline 6, the first ultraviolet germicidal lamp can be turned on to sterilize the water stored in the first water storage unit 4. Through this process, the ultraviolet germicidal light of first sterilamp transmission can realize carrying out effectual disinfecting to the water of all areas in first water storage unit 4 to further improve the bactericidal rate to water.

When the user needs a large amount of cold water or a large amount of cold functional water, the user may give an instruction to the functional water supply device in advance, so that the functional water supply device is switched to the third operation state. When the functional water supply device enters the third operation state, the refrigeration unit 2 may be turned on to cool the water in the first water storage unit 4.

The pressurizing device 1 is started, and water is made to circularly flow among the first water storage unit 4, the pressurizing device 1 and the second water storage unit 10. In this step, the supercharging device 1 may be turned on again after the temperature of water in the first water storage unit 4 is decreased to the second preset temperature by the refrigeration unit 2, or the supercharging device 1 may be turned on directly, or the supercharging device 1 may be turned on again after the water in the first water storage unit 4 is cooled to the third preset temperature, and water is made to flow in a circulating manner among the first water storage unit 4, the supercharging device 1, and the second water storage unit 10. The third preset temperature may be higher than the second preset temperature, that is, the water temperature in the first water storage unit 4 is decreased to a certain extent under the action of the refrigeration unit 2, but does not completely reach the second preset temperature, and the pressurization device 1 is started, so that it is ensured that the water in the first water storage unit 4 is supplied to the user or is input into the functional water generation unit 3 at the second preset temperature close to the second preset temperature set by the user, and the heat exchange rate between the whole water in the first water storage unit 4 and the second water storage unit 10 and the evaporator 21 in the refrigeration unit 2 is also considered. This is because the lower the temperature of the water in the first water storage unit 4 is, the lower the heat exchange rate between the first water storage unit and the evaporator 21 is, so that the supercharging device 1 can be opened reasonably early so that the normal temperature water in the second water storage unit 10 flows into the first water storage unit 4.

Through the effect of supercharging device 1, water circulates among first water storage unit 4, supercharging device 1, second water storage unit 10, and the water after the cooling in first water storage unit 4 is carried to in second water storage unit 10, and the water in second water storage unit 10 is mended into first water storage unit 4, so circulate, and the cooling can all be realized to the water in first water storage unit 4 and the second water storage unit 10.

The pressurizing means 1 may be turned off when the temperature of the water in the second water storage unit 10 reaches a second preset temperature. The second preset temperature may be a cold water temperature set by a user. Of course, the second water storage unit 10 may have a temperature measuring unit for measuring the temperature of water in the second water storage unit 10. Then, when the user needs cold water or cold functional water later, the functional water supply device can supply the cold water in the first water storage unit 4 to the user for use, and then can input the cold water in the second water storage unit 10 into the first water storage unit 4 and supply the cold water to the user through the first water storage unit 4, so that the effect of increasing the capacity of the first water storage unit 4 is achieved. Or, the functional water supply device may supply the cold functional water in the functional water generating unit 3 to a user, and then input the cold water in the first water storage unit 4 into the functional water generating unit 3, and simultaneously directly generate the cold functional water through the functional water generating unit 3 to be supplied to the user, after the cold water in the first water storage unit 4 is used up, the cold water in the second water storage unit 10 may supplement the first water storage unit 4, so that the functional water generating unit 3 may finally directly generate the cold functional water to be supplied to the user, and the cold functional water in the sum of the volume of the functional water generating unit 3 and the volume of the first water storage unit 4 and the volume of the second water storage unit 10 may be directly output in a short period of time. By the mode, the water demand of cold water or cold functional water under the condition of large water intake of a user is met.

In the above steps, in order to avoid the water temperature from rising due to the water supplied from the water source to the first water storage unit 4, it is feasible that the water source does not supply water to the first water storage unit 4 when the user takes a large amount of cold water or cold functional water, so as to ensure that the cold water or cold functional water supplied to the user is at the temperature set by the user.

As a matter of course, when the pressurizing device 1 is turned on and water is circulated among the first water storage unit 4, the pressurizing device 1, and the second water storage unit 10, the second ultraviolet germicidal lamp may be turned on to sterilize the water stored in the second water storage unit 10, and/or the first ultraviolet germicidal lamp may be turned on to sterilize the water stored in the first water storage unit 4. Through this process, the ultraviolet germicidal light of first sterilamp and/or second sterilamp transmission just can realize carrying out effectual disinfecting to the water of all regions in first water storage unit 4 and the second water storage unit 10 to further improve the sterilization rate to water. Since there is no shielding in the second water storage unit 10, the second ultraviolet germicidal lamp has a relatively better germicidal effect on the water stored in the second water storage unit 10.
