The normal temperature water tank 121 is communicated with the water purification unit 110, and is respectively communicated with the normal temperature branch 122 and the instant heating branch 123. A heating element 1231 for heating water is provided on the instant heating branch 123.

[0044] The high temperature water supply unit 130 includes a high temperature water tank 131, a high temperature water inlet branch 132, and a high temperature water outlet branch 133. The high temperature water inlet branch 132 is respectively communicated with one end of the instant heating branch 123 away from the normal temperature water tank 121 and the high temperature water tank 131. The high temperature water outlet branch 133 is respectively communicated with the high temperature water tank 131 and one end of the heating element 1231 close to the normal temperature water tank 121. The heating element 1231 is located between the connection position of the high temperature water outlet branch 133 and the instant heating branch 123 and the connection position of the high temperature water inlet branch 132 and the instant heating branch 123.

[0045] The water outlet unit 140 is respectively communicated with one end of the instant heating branch 123 away from the normal temperature water tank 121 and the high temperature water inlet branch 132, and is communicated with the normal temperature branch 122.

[0046] For the water supply device 100 provided by the embodiment of the present application, by communicating the normal temperature water tank 121 with the water purification unit 110, external tap water can be filtered and purified by the water purification unit 110 and then enter the normal temperature water tank 121 to form normal temperature pure water for users to use. By communicating the normal temperature branch 122 with the normal temperature water tank 121 and the water outlet unit 140 respectively, the normal temperature pure water in the normal temperature water tank 121 can be discharged through the normal temperature branch 122 via the water outlet unit 140 for users to use.

[0047] By connecting the instant heating branch 123 to the normal temperature water tank 121 and the water outlet unit 140 respectively, and arranging a heating element 1231 on the instant heating branch 123, the normal temperature pure water in the normal temperature water tank 121 can pass through the instant heating branch 123 and be heated by the heating element 1231 on the instant heating branch 123 to form high temperature pure water, and then be discharged through the water outlet unit 140 for users to use. At the same time, by connecting the high temperature inlet water branch 132 to one end of the instant heating branch 123 far from the normal temperature water tank 121 and the high temperature water tank 131 respectively, connecting the high temperature outlet water branch 133 to the high temperature water tank 131 and one end of the heating element 1231 close to the normal temperature water tank 121 respectively, and arranging the heating element 1231 between the connection position of the high temperature outlet water branch 133 and the instant heating branch 123 and the connection position of the high temperature inlet water branch 132 and the instant heating branch 123, the normal temperature pure water in the normal temperature water tank 121 can pass through the instant heating branch 123 and be heated by the heating element 1231 on the instant heating branch 123 to form high temperature pure water, and then enter the high temperature water tank 131 through the high temperature inlet water branch 132 and be stored in the high temperature water tank 131.

[0048] In this way, when the user needs to use a large amount of high temperature pure water, the high temperature pure water stored in the high temperature water tank 131 is first discharged through the high temperature outlet water branch 133, the instant heating branch 123 and the water outlet unit 140 for the user to use. After the remaining amount of the high temperature pure water stored in the high temperature water tank 131 is insufficient or completely discharged, the normal temperature pure water in the normal temperature water tank 121 continues to pass through the instant heating branch 123 and is heated by the heating element 1231 on the instant heating branch 123 to form high temperature pure water, and then is discharged through the water outlet unit 140 for the user to use, so as to meet the user's demand for using a large amount of high temperature pure water, effectively improving the efficiency of generating high temperature pure water, being able to continuously discharge high temperature pure water for the user to use, greatly reducing the waiting time for the user to heat, and the normal temperature pure water in the normal temperature water tank 121 can be discharged through the normal temperature branch 122 through the water outlet unit 140 for the user to use. Thus, the user can pick up normal temperature pure water, high temperature pure water according to the demand, or obtain pure water at different temperatures by mixing normal temperature pure water and high temperature pure water in different proportions according to the demand, so as to meet the diverse needs of the user.

[0049] Exemplarily, the heating element 1231 can be a metal heating wire with a large resistance value, the water outlet unit 140 can be a water outlet faucet, and the normal temperature branch 122, the instant heating branch 123, the high temperature inlet water branch 132 and the high temperature outlet water branch 133 can all be water pipes.

[0050] Such as Figure 1As shown, in an embodiment of the present application, the water supply device 100 further includes a driving assembly, the driving assembly includes a first driving member 151, a second driving member 152 and a third driving member 153. The first driving member 151 is arranged on the normal temperature branch 122, the second driving member 152 is arranged on the instant heating branch 123, and the third driving member 153 is arranged on the high-temperature water outlet branch 133.

[0051] In this embodiment, by arranging the first driving member 151 on the normal temperature branch 122, under the action of the first driving member 151, the normal temperature pure water in the normal temperature water tank 121 is transported from the normal temperature branch 122 to the water outlet unit 140 and discharged through the water outlet unit 140 for users to use.

[0052] By arranging the second driving member 152 on the instant heating branch 123, under the action of the second driving member 152, the normal temperature pure water in the normal temperature water tank 121 is transported from the instant heating branch 123 to the position of the heating element 1231 and heated by the heating element 1231. The high-temperature pure water formed after heating is transported from the instant heating branch 123 to the high-temperature water tank 131 through the high-temperature water inlet branch 132, or transported from the instant heating branch 123 to the water outlet unit 140 and discharged through the water outlet unit 140 for users to use.

[0053] By arranging the third driving member 153 on the high-temperature water outlet branch 133, under the action of the third driving member 153, the high-temperature pure water in the high-temperature water tank 131 is successively transported from the high-temperature water outlet branch 133 and the instant heating branch 123 to the water outlet unit 140 and discharged through the water outlet unit 140 for users to use.

[0054] Exemplarily, the first driving member 151, the second driving member 152 and the third driving member 153 can all be water pumps.

[0055] Such as Figure 1 As shown, in the above embodiment of the present application, the water supply device 100 further includes a control unit and a detection assembly. The detection assembly includes a liquid level detection sensor 161 and a temperature detection sensor 162. The liquid level detection sensor 161 and the temperature detection sensor 162 are both arranged in the high-temperature water tank 131 and are both electrically connected to the control unit. The heating element 1231, the first driving member 151, the second driving member 152 and the third driving member 153 are all electrically connected to the control unit.

[0056] In this embodiment, by electrically connecting the first driving member 151 to the control unit, when a user needs to use normal temperature purified water, the control unit controls the first driving member 151 to automatically turn on, so that under the action of the first driving member 151, the normal temperature purified water in the normal temperature water tank 121 is conveyed by the normal temperature branch 122 to the water outlet unit 140 and discharged through the water outlet unit 140 for the user to use.

[0057] By arranging the liquid level detection sensor 161 electrically connected to the control unit in the high-temperature water tank 131, when the remaining amount of high-temperature purified water in the high-temperature water tank 131 is insufficient, the liquid level detection sensor 161 feeds back a water shortage signal to the control unit, and the control unit controls the second driving member 152 and the heating element 1231 to automatically turn on according to this signal, so that the normal temperature purified water in the normal temperature water tank 121 is conveyed by the instant heating branch 123 to the position of the heating element 1231 and heated by the heating element 1231. The high-temperature purified water formed after heating is conveyed into the high-temperature water tank 131 through the instant heating branch 123 and the high-temperature water inlet branch 132; when the high-temperature purified water in the high-temperature water tank 131 is about to overflow, the liquid level detection sensor 161 feeds back a water full signal to the control unit, and the control unit controls the second driving member 152 and the heating element 1231 to automatically turn off according to this signal to stop conveying high-temperature purified water into the high-temperature water tank 131, realizing the functions of automatically supplementing high-temperature purified water into the high-temperature water tank 131 at low liquid level and automatically stopping supplementing high-temperature purified water into the high-temperature water tank 131 at high liquid level.

[0058] By arranging the temperature detection sensor 162 electrically connected to the control unit in the high-temperature water tank 131, when the high-temperature purified water stored in the high-temperature water tank 131 is not discharged for the user to use for a long time and naturally cools below the preset temperature, the temperature detection sensor 162 feeds back this signal to the control unit, and the control unit controls the third driving member 153 and the heating element 1231 to turn on according to the signal fed back by the temperature detection sensor 162, so that the purified water below the preset temperature in the high-temperature water tank 131 is conveyed by the high-temperature water outlet branch 133 to the position of the heating element 1231 and heated by the heating element 1231. The high-temperature purified water formed after heating is conveyed into the high-temperature water tank 131 through the instant heating branch 123 and the high-temperature water inlet branch 132, so that the purified water in the high-temperature water tank 131 always remains at a high temperature for the user to use at any time.

[0059] Thus, when the user needs to use a large amount of high-temperature purified water, the control unit controls the third driving member 153 to automatically turn on so that the high-temperature purified water stored in the high-temperature water tank 131 is first discharged through the high-temperature water outlet branch 133, the instant heating branch 123, and the water outlet unit 140 in sequence for the user to use. After the remaining amount of high-temperature purified water stored in the high-temperature water tank 131 is insufficient or completely discharged, the control unit controls the second driving member 152 and the heating element 1231 to automatically turn on according to the water shortage signal fed back by the liquid level detection sensor 161, so that the normal-temperature purified water in the normal-temperature water tank 121 continuously passes through the instant heating branch 123 and is heated by the heating element 1231 on the instant heating branch 123 to form high-temperature purified water, and then is discharged through the water outlet unit 140 for the user to use, so as to meet the user's demand for using a large amount of high-temperature purified water, effectively improving the efficiency of generating high-temperature purified water, being able to continuously discharge high-temperature purified water for the user to use, greatly reducing the user's waiting time for heating, and the control unit can also control the first driving member 151 to automatically turn on so that the normal-temperature purified water in the normal-temperature water tank 121 is conveyed to the water outlet unit 140 through the normal-temperature branch 122 and discharged through the water outlet unit 140 for the user to use. Thus, the user can pick up normal-temperature purified water and high-temperature purified water according to needs, or obtain purified water at different temperatures by mixing normal-temperature purified water and high-temperature purified water in different proportions according to needs, thereby meeting the diverse needs of the user.

[0060] Exemplarily, the liquid level detection sensor 161 may include a high liquid level probe and a low liquid level probe, and the temperature detection sensor 162 may be a thermistor.

[0061] As Figure 1 shown, in the above embodiment of the present application, the water supply device 100 further includes a first control valve 171. The first control valve 171 is respectively communicated with the instant heating branch 123 and the high-temperature water inlet branch 132, and is communicated with the water outlet unit 140. The first control valve 171 is electrically connected to the control unit.

[0062] In this embodiment, the first control valve 171 electrically connected to the control unit is respectively communicated with the instant heating branch 123, the high-temperature water inlet branch 132 and the water outlet unit 140. In this way, when the user needs to use high-temperature purified water, the control unit controls the first control valve 171 to cut off the instant heating branch 123 from the high-temperature water inlet branch 132 and communicate the instant heating branch 123 with the water outlet unit 140, so that the high-temperature purified water can be transported to the water outlet unit 140 through the instant heating branch 123 and discharged through the water outlet unit 140 for the user to use. When high-temperature purified water needs to be supplemented in the high-temperature water tank 131 or the purified water with a temperature lower than the preset temperature is circulated and heated, the control unit controls the first control valve 171 to communicate the instant heating branch 123 with the high-temperature water inlet branch 132 and cut off the instant heating branch 123 from the water outlet unit 140, so that the high-temperature purified water formed by heating by the heating element 1231 can enter the high-temperature water tank 131 from the instant heating branch 123 through the high-temperature water inlet branch 132.

[0063] Exemplarily, the first control valve 171 can be a three-way solenoid valve.

[0064] As Figure 2 shown, in an embodiment of the present application, the water supply device 100 further includes a driving assembly. The driving assembly includes a first driving member 151 and a second driving member 152. The first driving member 151 is arranged on the normal-temperature branch 122, and the second driving member 152 is arranged on the instant heating branch 123 and located between the connection position of the high-temperature water outlet branch 133 and the instant heating branch 123 and the heating element 1231.

[0065] In this embodiment, by arranging the first driving member 151 on the normal-temperature branch 122, the normal-temperature purified water in the normal-temperature water tank 121 is transported to the water outlet unit 140 through the normal-temperature branch 122 under the action of the first driving member 151 and discharged through the water outlet unit 140 for the user to use.

[0066] By arranging the second driving member 152 on the instant heating branch 123 between the connection position of the high-temperature water outlet branch 133 and the instant heating branch 123 and the heating element 1231, the normal-temperature purified water in the normal-temperature water tank 121 is transported to the position of the heating element 1231 through the instant heating branch 123 under the action of the second driving member 152 and heated by the heating element 1231. The high-temperature purified water formed after heating is transported to the high-temperature water tank 131 from the instant heating branch 123 through the high-temperature water inlet branch 132, or is transported to the water outlet unit 140 through the instant heating branch 123 and discharged through the water outlet unit 140 for the user to use; in addition, the high-temperature purified water in the high-temperature water tank 131 can also be transported to the water outlet unit 140 through the high-temperature water outlet branch 133 and the instant heating branch 123 in sequence under the action of the second driving member 152 and discharged through the water outlet unit 140 for the user to use.

[0067] Exemplarily, both the first driving member 151 and the second driving member 152 can be water pumps.

[0068] As Figure 2 shown, in the above-mentioned embodiment of the present application, the water supply device 100 further includes a control unit and a detection component. The detection component includes a liquid level detection sensor 161 and a temperature detection sensor 162. The liquid level detection sensor 161 and the temperature detection sensor 162 are both arranged in the high-temperature water tank 131 and are both electrically connected to the control unit. The heating element 1231, the first driving member 151, and the second driving member 152 are all electrically connected to the control unit.

[0069] In this embodiment, by electrically connecting the first driving member 151 to the control unit, when the user needs to use normal-temperature pure water, the control unit controls the first driving member 151 to automatically turn on, so that under the action of the first driving member 151, the normal-temperature pure water in the normal-temperature water tank 121 is conveyed by the normal-temperature branch 122 to the water outlet unit 140 and discharged through the water outlet unit 140 for the user to use.

[0070] By arranging the liquid level detection sensor 161 electrically connected to the control unit in the high-temperature water tank 131, when the remaining amount of high-temperature pure water in the high-temperature water tank 131 is insufficient, the liquid level detection sensor 161 feeds back a water shortage signal to the control unit. The control unit controls the second driving member 152 and the heating element 1231 to automatically turn on according to this signal, so that the normal-temperature pure water in the normal-temperature water tank 121 is conveyed by the instant heating branch 123 to the position of the heating element 1231 and is heated by the heating element 1231. The high-temperature pure water formed after heating is conveyed from the instant heating branch 123 to the high-temperature water tank 131 through the high-temperature water inlet branch 132; when the high-temperature pure water in the high-temperature water tank 131 is about to overflow, the liquid level detection sensor 161 feeds back a water full signal to the control unit. The control unit controls the second driving member 152 and the heating element 1231 to automatically turn off according to this signal, so as to stop conveying high-temperature pure water into the high-temperature water tank 131, realizing the functions of automatically supplementing high-temperature pure water into the high-temperature water tank 131 at low liquid level and automatically stopping supplementing high-temperature pure water into the high-temperature water tank 131 at high liquid level.

[0071] By arranging the temperature detection sensor 162 electrically connected to the control unit inside the high-temperature water tank 131, when the high-temperature purified water stored in the high-temperature water tank 131 has not been discharged for a long time for the user to use and naturally cools below the preset temperature, the temperature detection sensor 162 feeds back this signal to the control unit. The control unit controls the second driving member 152 and the heating element 1231 to turn on according to the signal fed back by the temperature detection sensor 162, so as to successively convey the purified water below the preset temperature in the high-temperature water tank 131 to the position of the heating element 1231 through the high-temperature water outlet branch 133 and the instant heating branch 123 to be heated by the heating element 1231. The high-temperature purified water formed after heating is conveyed into the high-temperature water tank 131 through the instant heating branch 123 and the high-temperature water inlet branch 132, so that the purified water in the high-temperature water tank 131 always remains at a high temperature for the user to use at any time.

[0072] Exemplarily, the liquid level detection sensor 161 may include a high liquid level probe and a low liquid level probe, and the temperature detection sensor 162 may be a thermistor.

[0073] As Figure 2 As shown, in the above-mentioned embodiment of the present application, the water supply device 100 further includes a first control valve 171, a second control valve 172 and a third control valve 173. The first control valve 171 is respectively communicated with the instant heating branch 123, the high-temperature water inlet branch 132 and the water outlet unit 140, and is communicated with the water outlet unit 140. The second control valve 172 is arranged on the instant heating branch 123 and is located between the connection position of the high-temperature water outlet branch 133 and the instant heating branch 123 and the normal-temperature water tank 121. The third control valve 173 is arranged on the high-temperature water outlet branch 133. The first control valve 171, the second control valve 172 and the third control valve 173 are all electrically connected to the control unit.

[0074] In this embodiment, by respectively communicating the first control valve 171 electrically connected to the control unit with the instant heating branch 123, the high-temperature water inlet branch 132 and the water outlet unit 140, when the user needs to use high-temperature purified water, the control unit controls the first control valve 171 to cut off the connection between the instant heating branch 123 and the high-temperature water inlet branch 132, and make the connection between the instant heating branch 123 and the water outlet unit 140, so that the high-temperature purified water can be conveyed to the water outlet unit 140 through the instant heating branch 123 and discharged through the water outlet unit 140 for the user to use. When the high-temperature water tank 131 needs to be replenished with high-temperature purified water or circularly heated purified water below the preset temperature, the control unit controls the first control valve 171 to connect the instant heating branch 123 and the high-temperature water inlet branch 132, and cut off the connection between the instant heating branch 123 and the water outlet unit 140, so that the high-temperature purified water formed by heating by the heating element 1231 can enter the high-temperature water tank 131 from the instant heating branch 123 through the high-temperature water inlet branch 132.

[0075] By arranging the second control valve 172 electrically connected to the control unit on the instant heating branch 123, at a position between the connection position of the high-temperature water outlet branch 133 and the instant heating branch 123 and the normal-temperature water tank 121, and arranging the third control valve 173 electrically connected to the control unit on the high-temperature water outlet branch 133. In this way, when the user needs to use a large amount of high-temperature purified water, the control unit controls the second driving member 152 and the third control valve 173 to automatically open and the second control valve 172 to automatically close, so as to first discharge the high-temperature purified water stored in the high-temperature water tank 131 through the high-temperature water outlet branch 133, the instant heating branch 123 and the water outlet unit 140 in sequence for the user to use. After the remaining amount of the high-temperature purified water stored in the high-temperature water tank 131 is insufficient or completely discharged, the control unit controls the second driving member 152, the heating element 1231 and the second control valve 172 to automatically open and the third control valve 173 to close according to the water shortage signal fed back by the liquid level detection sensor 161, so as to continuously pass the normal-temperature purified water in the normal-temperature water tank 121 through the instant heating branch 123 and heat it by the heating element 1231 on the instant heating branch 123 to form high-temperature purified water and then discharge it through the water outlet unit 140 for the user to use, so as to meet the user's demand for using a large amount of high-temperature purified water, effectively improve the efficiency of generating high-temperature purified water, be able to continuously discharge high-temperature purified water for the user to use, greatly reduce the user's waiting time for heating, and the control unit can also control the first driving member 151 to automatically open to convey the normal-temperature purified water in the normal-temperature water tank 121 from the normal-temperature branch 122 to the water outlet unit 140 and discharge it through the water outlet unit 140 for the user to use. Thus, the user can pick up normal-temperature purified water, high-temperature purified water according to needs, or obtain purified water at different temperatures by mixing normal-temperature purified water and high-temperature purified water in different proportions according to needs, thereby meeting the diverse needs of the user.

[0076] Exemplarily, the first control valve 171 can be a three-way solenoid valve, and both the second control valve 172 and the third control valve 173 can be solenoid valves.

[0078] In this embodiment, by arranging a vacuum insulation container in the high-temperature water tank 131 that is respectively communicated with the high-temperature water inlet branch 132 and the high-temperature water outlet branch 133, the high-temperature purified water is stored in the vacuum insulation container, thereby playing a role in heat preservation for the high-temperature purified water, so as to delay the drop of the water temperature, and further reduce the number of times of circulating heating of the purified water below the preset temperature, which is beneficial to reducing energy consumption and saving usage costs.
