Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, and particularly provides an instant heating component and a water purifying and drinking device including the instant heating component. Background Art

[0002] With the improvement of people's living standards, the demand for drinking water is also increasing. Water purification devices such as water purifiers and pipeline machines have gradually become essential drinking facilities in people's daily lives.

[0003] Taking the pipeline machine as an example, existing pipeline machines generally heat water through an instant heating element to achieve the function of discharging hot water. However, in actual use, the water heated by the pipeline machine is generally below 95°C and cannot reach 100°C of real boiling water, resulting in a poor user experience. If the instant heating element is directly heated to boiling, although the instant heating element can be heated to 100°C, during the boiling process, the hot water in the instant heating tube will vaporize, causing the top of the heating element to be occupied by water vapor. The part occupied by water vapor has no water, which will cause local dry burning and lead to phenomena such as film bursting, seriously affecting the user experience. Summary of the Utility Model

[0004] The utility model aims to solve at least to some extent the above technical problems, that is, to solve at least to some extent the problem that the existing instant heating element causes local dry burning due to the vaporization of hot water during heating, thereby resulting in a poor user experience.

[0005] In a first aspect, the utility model provides an instant heating component, which includes a heating body. The heating body has a heating chamber and a heating element. A heating area and a protection area are sequentially arranged in the heating chamber. The heating element is arranged outside the heating area and can heat the water in the heating area. The projection of the protection area in the vertical direction is higher than the projection of the heating area in the vertical direction.

[0006] In a preferred technical solution of the above instant heating component, the heating body includes a heating tube and a protection tube. The heating tube and the protection tube jointly enclose the heating chamber. The heating element is arranged outside the heating tube and the heating area is formed inside the heating tube. The protection tube is arranged above the heating tube and is hermetically connected to the heating tube. The protection area is formed inside the protection tube.

[0007] In a preferred technical solution of the above instant heating component, the protection tube is fixedly connected to or integrally formed with the heating tube; and / or, the depth of the protection area is at least 10 mm.

[0008] In the preferred technical solution of the above-mentioned instant heating assembly, the protection area includes a submerged area and a boiling area. The submerged area is arranged between the heating area and the boiling area. The boiling area is used to accommodate the steam generated by heating the water in the heating chamber. The instant heating assembly further includes a water outlet pipe. The water outlet pipe is arranged at one end of the protection pipe away from the heating pipe and extends in the direction of the protection area. At least a part of the water outlet pipe extends into the submerged area. The water outlet pipe and the protection pipe jointly enclose the boiling area.

[0009] In the preferred technical solution of the above-mentioned instant heating assembly, the protection pipe is fixedly connected to or integrally formed with the water outlet pipe; and / or, the length of the water outlet pipe extending into the protection area is at least 5 mm.

[0010] In the preferred technical solution of the above-mentioned instant heating assembly, the instant heating assembly further includes a water temperature detection component. The water temperature detection component is used to detect the water temperature at the water inlet end and / or the water outlet end of the heating chamber; and / or, the instant heating assembly further includes a temperature control protection component. The temperature control protection component is arranged on the heating pipe and is configured to cut off the power supply to the heating element when the temperature of the heating pipe exceeds a preset temperature.

[0011] In the preferred technical solution of the above-mentioned instant heating assembly, the instant heating assembly further includes a water inlet pipe. The water temperature detection component includes a water inlet temperature detection unit. The water inlet temperature detection unit is arranged on the water inlet pipe and is used to detect the water temperature at the water inlet end of the heating chamber; and / or, the water temperature detection component includes a water outlet temperature detection unit. The water outlet temperature detection unit is arranged on the protection pipe and is used to detect the water temperature at the water outlet end of the heating chamber.

[0012] In the preferred technical solution of the above-mentioned instant heating assembly, the temperature control protection component includes a manual temperature control protector. A temperature control switch is arranged on the manual temperature control protector so that the user can operate the temperature control switch to cut off the power supply to the heating element; and / or, the temperature control protection component includes an automatic temperature control protector. The automatic temperature control protector is configured to automatically cut off the power supply to the heating element when the temperature of the heating pipe exceeds a preset temperature.

[0013] In a second aspect, the present invention further provides a water purification device, and the water purification device includes the instant heating assembly described in any one of the above introductions.

[0014] In the preferred technical solution of the above water purification equipment, the water dispenser further includes a thermal insulation tank, a water pump, and a water outlet component. The water pump is arranged between the thermal insulation tank and the heating chamber and is used to convey the water in the thermal insulation tank to the heating chamber. The water outlet end of the heating chamber can be selectively communicated with the thermal insulation tank or the water outlet component.

[0015] In the case of adopting the above preferred technical solution, by sequentially arranging a heating area and a protection area in the heating chamber, the heating element can only heat the water in the heating area, avoiding the phenomenon of local dry burning caused by the vaporization of water vapor in the protection area when the heating element is arranged outside the protection area. Thus, the instant heating component can not only heat the water in the heating area to boiling but also avoid local dry burning, and further avoid phenomena such as membrane bursting, greatly improving the user experience.

[0016] Furthermore, by arranging at least a part of the water outlet pipe to extend into the submerged area, it is possible to avoid the steam at the top of the heating chamber being discharged through the water outlet pipe, resulting in phenomena such as water outlet interruption and jitter. Thus, the hot water in the heating chamber is directly discharged through the water outlet pipe, greatly improving the water outlet effect.

[0017] Still further, by arranging a water temperature detection component, it is convenient to detect the water temperature at the water inlet end and the water outlet end of the heating chamber, so as to facilitate the user to understand the inlet water temperature and the heating temperature, and further improve the user experience; by arranging a temperature control protection component, when the temperature of the heating pipe exceeds the preset temperature, the heating element can be timely cut off from power supply, avoiding the continuous heating of the heating element and further increase in the temperature of the heating pipe, and further avoiding dry burning, improving the use safety of the instant heating component.

[0018] Furthermore, by arranging the temperature control protection component to include a manual temperature control protector and an automatic temperature control protector, automatic temperature control protection can be realized. When the temperature of the heating pipe exceeds the preset temperature, the heating element is automatically cut off from power supply to prevent the heating element from dry burning. At the same time, when the automatic temperature control protector fails, the heating element can also be cut off from power supply by operating the manual temperature control protector, improving the use safety of the instant heating component and further enhancing the user experience.

[0019] In addition, the water dispenser further provided by the present utility model on the basis of the above technical solution includes the above-described instant heating component, and thus has the beneficial effects of the above instant heating component. Compared with the water dispenser before improvement, the hot water outlet temperature of the water dispenser of the present utility model is closer to boiling water, the instant heating component is less likely to dry burn, has higher use safety, and better user experience.

[0020] Furthermore, by setting the water outlet end of the heating chamber to be selectively communicable with the water outlet member or the heat preservation tank, when it is detected that the temperature of the water outlet end of the heating chamber has not reached the preset temperature, the water outlet end of the heating chamber is made to communicate with the heat preservation tank, so as to prevent water that does not meet the requirements at the water outlet end of the heating chamber from flowing out through the water outlet member. When it is detected that the temperature of the water outlet end of the heating chamber reaches the preset temperature, the water outlet end of the heating chamber is made to communicate with the water outlet member, so that the hot water meeting the user's requirements in the heating chamber flows out through the water outlet member, avoiding affecting the user's experience due to too large a deviation between the actual hot water temperature and the set temperature.

For example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] Based on the problems mentioned in the background technology that the existing instant heating element has problems such as local dry burning and film bursting due to hot water vaporization during heating, resulting in a poor user experience, the present utility model provides an instant heating assembly.

[0032] Specifically, please refer to Figure 1 and Figure 2 , Figure 1 is a schematic structure of the instant heating assembly of the present utility model Figure 1 ; Figure 2 is a schematic structure of the instant heating assembly of the present utility model Figure 2 .

[0033] As Figure 1 and Figure 2 shown, the instant heating assembly 1 of the present utility model includes a heating element, the heating element has a heating chamber 10 and a heating member 12, a heating area 101 and a protection area 102 are sequentially arranged in the heating chamber 10, the heating member 12 is arranged outside the heating area 101 and is used to heat the water in the heating area 101, and the projection of the protection area 102 in the vertical direction is higher than the projection of the heating area 101 in the vertical direction.

[0034] With such a setting, that is, by sequentially arranging a heating area 101 and a protection area 102 in the heating chamber 10 and arranging the heating element 12 outside the heating area 101, the heating element 12 can only heat the water in the heating area 101, avoiding the phenomenon of local dry burning caused by the vaporization of the water vapor in the protection area 102 when the heating element 12 is arranged outside the protection area 102. Thus, the instant heating assembly 1 can not only heat the water in the heating area 101 to boiling, facilitating the heating to obtain real boiling water, but also avoid local dry burning, and further avoid phenomena such as film bursting, greatly improving the user experience.

[0035] It should be noted that the present utility model does not make any limitation on the specific structural form of the heating body, as long as it can heat the water in the heating area 101, etc. Such adjustments and changes to the specific structural form of the heating body do not deviate from the principle and scope of the present utility model and should be included in the protection scope of the present utility model.

[0036] In a specific embodiment, the heating body includes a pipe body and a heating element (not shown in the figure). The pipe body includes a heating section and a protection section arranged in sequence, and the heating element is arranged on the heating section.

[0037] In another specific embodiment, the heating body includes a heating pipe 111 and a protection pipe 112. The heating pipe 111 and the protection pipe 112 jointly enclose the heating chamber 10. The heating element 12 is arranged outside the heating pipe 111, and a heating area 101 is formed inside the heating pipe 111. The protection pipe 112 is arranged above the heating pipe 111 and is hermetically connected to the heating pipe 111, and a protection area 102 is formed inside the protection pipe 112.

[0038] Preferably, as Figure 1 and Figure 2 shown, the heating body includes a heating pipe 111 and a protection pipe 112 arranged in sequence. The heating pipe 111 and the protection pipe 112 jointly enclose the heating chamber 10. Among them, the heating element 12 is arranged outside the heating pipe 111, a heating area 101 is formed inside the heating pipe 111, a protection area 102 is formed inside the protection pipe 112, and the protection pipe 112 is located above the heating pipe 111 and is hermetically connected to the heating pipe 111.

[0039] With such a setting, compared with the form of setting the heating body as a pipe body and a heating element, and the pipe body includes a heating section and a protection section, setting the heating body as a form including a heating pipe 111 and a protection pipe 112 can reduce the processing difficulty of the instant heating assembly 1, improve the processing efficiency of the instant heating assembly 1, and at the same time, it can also facilitate the cooperation of the protection pipe 112 with the heating pipe 111 in the prior art, further improving the user experience.

[0040] It should be noted that in practical applications, those skilled in the art can set the heating element 12 as a heating resistor sprayed on the outer part of the heating tube 111, or the heating element 12 can also be set as an electromagnetic heating coil wound around the outer part of the heating tube 111, etc. Such adjustments and changes to the specific setting type of the heating element 12 do not deviate from the principle and scope of the present utility model and should be included within the protection scope of the present utility model.

[0041] Preferably, the heating element 12 is a heating resistor sprayed on the outer part of the heating tube 111.

[0042] Preferably, the depth of the protection area 102 is at least 10 mm.

[0043] It should be noted that in practical applications, those skilled in the art can set the depth of the protection area 102 to 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm or the range composed of any two of the above values, etc. Such adjustments and changes to the depth of the protection area 102 do not deviate from the principle and scope of the present utility model and should be included within the protection scope of the present utility model.

[0044] Exemplarily, the depth of the protection area 102 is 12 mm.

[0045] It should be noted that in practical applications, those skilled in the art can set the protection tube 112 to be welded to the heating tube 111, or the protection tube 112 can also be set to be threadedly connected to the heating tube 111, or the protection tube 112 can further be set to be hermetically connected to the heating tube 111 through a seal, etc. Such adjustments and changes to the specific connection manner between the protection tube 112 and the heating tube 111 do not deviate from the principle and scope of the present utility model and should be included within the protection scope of the present utility model.

[0046] Preferably, the protection tube 112 is welded to the heating tube 111.

[0047] Through such a setting, compared with the form of setting the protection tube 112 to be threadedly connected to the heating tube 111, setting the protection tube 112 to be welded to the heating tube 111 can improve the connection stability and sealing performance between the protection tube 112 and the heating tube 111, reduce the risk of water leakage, and further enhance the user experience.

[0048] Preferably, as Figure 2As shown, the protection area 102 includes a submerged area 1021 and a boiling area 1022. The submerged area 1021 is arranged between the heating area 101 and the boiling area 1022. The boiling area 1022 is used to accommodate the steam generated by heating the water in the heating chamber 10. That is, the instant heating assembly 1 further includes a water outlet pipe 131. The water outlet pipe 131 is arranged at one end of the protection pipe 112 away from the heating pipe 111 and extends in the direction of the protection area 102. At least a part of the water outlet pipe 131 extends into the submerged area 1021 so that the water in the submerged area 1021 can enter the water outlet pipe 131. The water outlet pipe 131 and the protection pipe 112 together enclose the boiling area 1022.

[0049] With such an arrangement, since the water in the heating chamber 10 is heated and vaporized, the top area of the heating chamber 10 will be occupied by steam. By arranging the water outlet pipe 131 so that at least a part of it extends into the protection area 102, it is possible to avoid the steam at the top of the heating chamber 10 being discharged through the water outlet pipe 131, resulting in phenomena such as water flow interruption and jitter. Thus, the hot water in the heating chamber 10 can be directly discharged through the water outlet pipe 131, greatly improving the water outlet effect.

[0050] It should be noted that in practical applications, those skilled in the art can set the water outlet pipe 131 to be integrally formed with the protection pipe 112, or the water outlet pipe 131 can also be set to be fixedly connected to the protection pipe 112, etc. Such adjustments and changes to the specific connection method between the water outlet pipe 131 and the protection pipe 112 do not deviate from the principle and scope of the present invention and should all be included in the protection scope of the present invention.

[0051] Preferably, the water outlet pipe 131 is integrally formed with the protection pipe 112.

[0052] It should be noted that in practical applications, those skilled in the art can set the length of the water outlet pipe 131 extending into the protection area 102 to be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, or the range composed of any two of these values, etc. Such adjustments and changes to the length of the water outlet pipe 131 extending into the protection area 102 do not deviate from the principle and scope of the present invention and should all be included in the protection scope of the present invention.

[0053] Exemplarily, the length of the water outlet pipe 131 extending into the protection area 102 is 5mm.

[0054] Preferably, as Figure 1 and Figure 2 shown, the instant heating assembly 1 of the present invention further includes a water temperature detection component, and the water temperature detection component is used to detect the water temperature at the water inlet end and / or the water outlet end of the heating chamber 10.

[0055] By setting up the water temperature detection component, it is convenient to detect the water temperature at the water inlet end and the water outlet end of the heating chamber 10, so as to facilitate the user to understand the inlet water temperature and the heating temperature, and further improve the user experience.

[0056] It should be noted that in practical applications, those skilled in the art can set the water temperature detection component to only include the inlet water temperature detection unit 141, or, the water temperature detection component can also be set to only include the outlet water temperature detection unit 142, or, the water temperature detection component can also be set to include the inlet water temperature detection unit 141 and the outlet water temperature detection unit 142, etc. Such adjustments and changes to the specific setting types of the water temperature detection component do not deviate from the principle and scope of the present utility model, and should all be included in the protection scope of the present utility model.

[0057] Preferably, as Figure 1 and Figure 2 shown, the water temperature detection component of the present utility model includes an inlet water temperature detection unit 141 and an outlet water temperature detection unit 142. Among them, the outlet water temperature detection unit 142 is arranged on the protection pipe 112 and is used to detect the water temperature at the water outlet end of the heating chamber 10. That is, the instant heating component 1 further includes an inlet pipe 132, and the inlet water temperature detection unit 141 is arranged on the inlet pipe 132 and is used to detect the water temperature at the water inlet end of the heating chamber 10.

[0058] It should be noted that in practical applications, it is not limited to arranging the outlet water temperature detection unit 142 on the protection pipe 112. For example, the outlet water temperature detection unit 142 can also be arranged at a position where the heating pipe 111 is close to the protection pipe 112, or, the outlet water temperature detection unit 142 can also be arranged on the outlet pipe 131, etc. Such adjustments and changes to the specific setting positions of the outlet water temperature detection unit 142 do not deviate from the principle and scope of the present utility model, and should all be included in the protection scope of the present utility model.

[0059] Certainly preferably, the outlet water temperature detection unit 142 is arranged on the protection pipe 112.

[0060] By arranging the outlet water temperature on the protection pipe 112, the outlet water temperature at the water outlet end of the heating chamber 10 can be detected more accurately.

[0061] It should also be noted that it is not limited to arranging the inlet water temperature detection unit 141 on the inlet pipe 132. For example, the inlet water temperature detection unit 141 can also be arranged at a position where the heating pipe 111 is far from the protection pipe 112, etc. Such adjustments and changes to the specific setting positions of the inlet water temperature detection unit 141 do not deviate from the principle and scope of the present utility model, and should all be included in the protection scope of the present utility model.

[0062] Preferably, the inlet water temperature detection unit 141 is disposed on the water inlet pipe 132.

[0063] With such an arrangement, compared with disposing the inlet water temperature detection unit 141 at a position on the heating pipe 111 away from the protection pipe 112, disposing the inlet water temperature detection unit 141 on the water inlet pipe 132 can more accurately detect the water temperature at the water inlet end of the heating chamber 10.

[0064] It should be noted that in practical applications, those skilled in the art can set the water inlet pipe 132 to be welded to the heating pipe 111, or the water inlet pipe 132 can be set to be threadedly connected to the heating pipe 111, or the water inlet pipe 132 can also be set to be hermetically connected to the heating pipe 111 through a sealing member, etc. Such adjustments and changes to the specific connection manner between the water inlet pipe 132 and the heating pipe 111 do not deviate from the principle and scope of the present utility model and should all be included within the protection scope of the present utility model.

[0065] Preferably, the water inlet pipe 132 is welded to the heating pipe 111.

[0066] In this way, the connection stability and sealing performance between the water inlet pipe 132 and the heating pipe 111 can be improved, and the risk of water leakage can be reduced.

[0067] Preferably, the instant heating assembly 1 of the present utility model further includes a temperature control protection member, which is disposed on the heating pipe 111 and is configured to cut off the power supply of the heating element 12 when the temperature of the heating pipe 111 exceeds a preset temperature.

[0068] By providing the temperature control protection member, the power supply of the heating element 12 can be timely cut off when the temperature of the heating pipe 111 exceeds the preset temperature, avoiding the continuous heating of the heating element 12 and further increase in the temperature of the heating pipe 111, thereby avoiding dry burning and improving the use safety of the instant heating assembly 1.

[0069] It should be noted that in practical applications, those skilled in the art can set the temperature control protection component as a manual temperature control protector 151, so that when the temperature of the heating tube 111 exceeds the preset temperature, the user can operate the temperature control switch of the manual temperature control protector 151 to cut off the power supply of the heating element 12. Or, the temperature control protection component can also be set as an automatic temperature control protector 152, which automatically cuts off the power supply of the heating element 12 when it detects that the temperature of the heating tube 111 exceeds the preset temperature. Or, the temperature control protection component can also be set to include a manual temperature control protector 151 and an automatic temperature control protector 152. When the automatic temperature control protector 152 fails, the heating element 12 can be cut off from the power supply through the manual temperature control protector 151, and so on. Such adjustments and changes to the specific setting types of the temperature control protection component do not deviate from the principle and scope of the present utility model and should all be included within the protection scope of the present utility model.

[0070] Preferably, the temperature control protection component includes a manual temperature control protector 151 and an automatic temperature control protector 152. A temperature control switch (not shown in the figure) is provided on the manual temperature control protector 151 for the user to operate the temperature control switch to cut off the power supply of the heating element 12, and the automatic temperature control protector 152 is set to automatically cut off the power supply of the heating element 12 when the temperature of the heating tube 111 exceeds the preset temperature.

[0071] By setting the temperature control protection component to include a manual temperature control protector 151 and an automatic temperature control protector 152, automatic temperature control protection can be achieved. When the temperature of the heating tube 111 exceeds the preset temperature, the power supply of the heating element 12 is automatically cut off to prevent the heating element 12 from dry burning. At the same time, when the automatic temperature control protector 152 fails, the power supply of the heating element 12 can also be cut off by operating the manual temperature control protector 151, improving the use safety of the instant heating assembly 1 and further enhancing the user experience.

[0072] In addition, the present utility model also provides a water purification and drinking device, which includes any one of the instant heating assemblies 1 introduced above.

[0073] It should be noted that in practical applications, the present utility model does not make any limitation on the specific type of the water purification and drinking device. For example, the water purification and drinking device can be set as a water dispenser, or it can also be set as a pipeline machine, or it can also be set as a combined water purification and heating machine, and so on. Such adjustments and changes to the specific setting types of the water purification and drinking device do not deviate from the principle and scope of the present utility model and should all be included within the protection scope of the present utility model.

[0074] Next, taking the pipeline machine as an example, the specific embodiments of the water purification and drinking device of the present utility model will be introduced in detail.

[0075] Specifically, then refer to Figure 3 andFigure 4 , Figure 3 is a schematic diagram of the connection structure of the first embodiment of the water purification device of the present utility model; Figure 4 is a schematic diagram of the connection structure of the second embodiment of the water purification device of the present utility model.

[0076] Preferably, as shown in Figure 3 and Figure 4 , the drinking water purification device of the present utility model further includes a heat preservation tank 2, a water pump 3 and a water outlet member 4. The water pump 3 is arranged between the heat preservation tank 2 and the instant heating component 1 and is used for conveying the water in the heat preservation tank 2 to the heating chamber 10. The instant heating component 1 can heat the water in the heating chamber 10, and the water outlet end of the heating chamber 10 can be selectively communicated with the water outlet member 4 or the heat preservation tank 2.

[0077] By providing the heat preservation tank 2, the water can be first heated to a set temperature, and then the water in the heat preservation tank 2 can be secondarily heated by the instant heating component 1 to improve the heating efficiency, and the heated hot water flows out from the water outlet member 4, facilitating the user to receive the hot water. By setting the water outlet end of the heating chamber 10 to be selectively communicable with the water outlet member 4 or the heat preservation tank 2, when it is detected that the temperature of the water outlet end of the heating chamber 10 has not reached the set temperature, the water outlet end of the heating chamber 10 is communicated with the heat preservation tank 2 to prevent the water that does not meet the requirements at the water outlet end of the heating chamber 10 from flowing out from the water outlet member 4. When it is detected that the temperature of the water outlet end of the heating chamber 10 reaches the set temperature, the water outlet end of the heating chamber 10 is communicated with the water outlet member 4, so that the hot water that meets the user's requirements in the heating chamber 10 flows out from the water outlet member 4, avoiding affecting the user's use experience due to too large a deviation between the actual hot water temperature and the set temperature.

[0078] It should be noted that the present utility model does not make any limitation on the specific communication method for the water outlet end of the heating chamber 10 to be selectively communicated with the heat preservation tank 2 or the water outlet member 4, as long as the water outlet end of the heating chamber 10 can be selectively communicated with the heat preservation tank 2 or the water outlet member 4.

[0079] In a specific embodiment, as shown in Figure 3 , the drinking water purification device of the present utility model further includes a hot water delivery pipe 51, a hot water outlet pipe 52, a return pipe 53 and a first reversing valve 5. One end of the hot water delivery pipe 51 is communicated with the water outlet end of the heating chamber 10, the other end of the hot water delivery pipe 51 is communicated with the first interface of the first reversing valve 5, the second interface of the first reversing valve 5 is communicated with the water outlet member 4 through the hot water outlet pipe 52, the third interface of the first reversing valve 5 is communicated with the heat preservation tank 2 through the return pipe 53, and the first interface of the first reversing valve 5 can be selectively communicated with the second interface or the third interface.

[0080] When it is detected that the temperature at the water outlet end of the heating chamber 10 has not reached the set temperature, the first interface of the first reversing valve 5 is communicated with the third interface, so that the water at the water outlet end of the heating chamber 10 flows back into the heat preservation tank 2 through the return pipe 53. When it is detected that the temperature at the water outlet end of the heating chamber 10 reaches the set temperature, the first interface of the first reversing valve 5 is communicated with the second interface, so that the water at the water outlet end of the heating chamber 10 is delivered to the water outlet member 4 through the hot water outlet pipe 52.

[0081] In another specific embodiment, as Figure 4 shown, the water purifying and drinking device of the present utility model further includes a hot water delivery pipe 51, a hot water outlet pipe 52, a return pipe 53, a first control valve 61 and a second control valve 62. Among them, one end of the hot water delivery pipe 51 is communicated with the water outlet end of the heating chamber 10, the other end of the hot water delivery pipe 51 is communicated with the hot water outlet pipe 52 and the return pipe 53, the first control valve 61 is arranged on the hot water outlet pipe 52 and is used to control the on-off of the hot water outlet pipe 52, and the second control valve 62 is arranged on the return pipe 53 and is used to control the on-off of the return pipe 53.

[0082] When it is detected that the temperature at the water outlet end of the heating chamber 10 has not reached the set temperature, the first control valve 61 is closed and the second control valve 62 is opened, so that the water at the water outlet end of the heating chamber 10 flows back into the heat preservation tank 2 through the return pipe 53. When it is detected that the temperature at the water outlet end of the heating chamber 10 reaches the set temperature, the first control valve 61 is opened and the second control valve 62 is closed, so that the water at the water outlet end of the heating chamber 10 is delivered to the water outlet member 4 through the hot water outlet pipe 52.

[0083] Although the above two embodiments can both realize the selective communication between the water outlet end of the heating chamber 10 and the heat preservation tank 2 or the water outlet member 4, compared with the form in which the water outlet end of the heating chamber 10 is set to selectively communicate with the heat preservation tank 2 or the water outlet member 4 by controlling the first control valve 61 and the second control valve 62, the form in which the water outlet end of the heating chamber 10 is set to selectively communicate with the heat preservation tank 2 or the water outlet member 4 by controlling the first reversing valve 5 can simplify the pipeline connection, improve the convenience of water path switching, and further enhance the user experience.

[0084] It should be noted that in practical applications, those skilled in the art can set the water outlet member 4 as a water outlet nozzle, or can also set the water outlet member 4 as a faucet, etc. Such adjustments and changes to the specific setting type of the water outlet member 4 do not deviate from the principle and scope of the present utility model and should be included in the protection scope of the present utility model.

[0085] Preferably, the water outlet member 4 is a water outlet nozzle.

[0086] Preferably, as Figure 3 and Figure 4As shown in the figure, the water purification and drinking device of the present utility model further includes a drainage member 8. The drainage member 8 is communicated with the water outlet end of the instant heating component 1 and is used to empty the water in the heating chamber 10.

[0087] By setting the drainage member 8, it is convenient to empty the water in the heating chamber 10, and it can avoid the growth of bacteria in the heating chamber 10 due to the stagnation of water in the heating chamber 10 when the instant heating component 1 is not used for a long time.

[0088] It should be noted that in practical applications, those skilled in the art can set the drainage member 8 as a drainage pipe 81 and a drainage valve 82 arranged on the drainage pipe 81. Among them, one end of the drainage pipe 81 is communicated with the water outlet end of the heating chamber 10, and the other end of the drainage pipe 81 is communicated with the drainage port 9 of the water purification and drinking device. The water in the heating chamber 10 is discharged to the drainage port 9 under the action of gravity. Or, the drainage member 8 can also be set as a drainage pipe 81 and a drainage pump arranged on the drainage pipe 81. Among them, one end of the drainage pipe 81 is communicated with the water outlet end of the heating chamber 10, and the other end of the drainage pipe 81 is communicated with the drainage port 9 of the water purification and drinking device. The drainage pump is used to transport the water in the heating chamber 10 to the drainage port 9, etc. Such adjustments and changes to the specific setting types of the drainage member 8 do not deviate from the principle and scope of the present utility model and should all be included in the protection scope of the present utility model.

[0089] Preferably, the drainage member 8 includes a drainage pipe 81 and a drainage valve 82. One end of the drainage pipe 81 is communicated with the water outlet end of the heating chamber 10, and the other end of the drainage pipe 81 is communicated with the drainage port 9 of the water purification and drinking device. The drainage valve 82 is arranged on the drainage pipe 81 and is used to control the on-off of the drainage pipe 81.

[0090] By such a setting, compared with setting the drainage member 8 in the form of including a drainage pipe 81 and a drainage pump, setting the drainage member 8 in the form of a drainage pipe 81 and a drainage valve 82 can avoid using a drainage pump, greatly reducing the cost of the water purification and drinking device and further improving the user experience.

[0091] It should be noted that in practical applications, those skilled in the art can set the drainage valve 82 as a manual valve, or the drainage valve 82 can also be set as an electromagnetic valve, etc. Such adjustments and changes to the specific setting types of the drainage valve 82 do not deviate from the principle and scope of the present utility model and should all be included in the protection scope of the present utility model.

[0092] Preferably, the drainage valve 82 is an electromagnetic valve.

[0093] Preferably, the water purifying and drinking device of the present utility model further includes a normal temperature water delivery pipe 71, a water replenishing pipe 72, and a normal temperature water outlet pipe 73. Among them, the water replenishing pipe 72 is communicated with the heat preservation tank 2, the normal temperature water outlet pipe 73 is communicated with the water outlet member 4, and the normal temperature water delivery pipe 71 can be selectively communicated with the water replenishing pipe 72 or the normal temperature water outlet pipe 73.

[0094] Through such a setting, on the one hand, when the amount of water in the heat preservation tank 2 is small, the normal temperature water delivery pipe 71 can be communicated with the water replenishing pipe 72, so as to facilitate water replenishment to the heat preservation tank 2. On the other hand, the normal temperature water delivery pipe 71 can also be communicated with the normal temperature water outlet pipe 73, so as to directly deliver normal temperature water to the water outlet member 4, facilitating the user to access normal temperature water.

[0095] It should be noted that the present utility model does not make any limitation on the specific connection method for the normal temperature water delivery pipe 71 to be selectively connected with the water replenishing pipe 72 or the normal temperature water outlet pipe 73, as long as the normal temperature water delivery pipe 71 can be selectively connected with the water replenishing pipe 72 or the normal temperature water outlet pipe 73.

[0096] In a specific embodiment, the water purifying and drinking device of the present utility model further includes a second reversing valve 7. The normal temperature water delivery pipe is communicated with the first interface of the second reversing valve 7. The second interface of the second reversing valve 7 is communicated with the water replenishing pipe 72. The third interface of the second reversing valve 7 is communicated with the normal temperature water outlet pipe 73. The first interface of the second reversing valve 7 can be selectively communicated with the second interface or the third interface of the second reversing valve 7.

[0097] In another specific embodiment, the water purifying and drinking device of the present utility model further includes a third control valve and a fourth control valve (not shown in the figure). The third control valve is arranged on the water replenishing pipe 72 and is used to control the on-off of the water replenishing pipe 72. The fourth control valve is arranged on the normal temperature water outlet pipe 73 and is used to control the on-off of the normal temperature water outlet pipe 73.

[0098] Preferably, the water purifying and drinking device of the present utility model further includes a second reversing valve 7. The normal temperature water delivery pipe is communicated with the first interface of the second reversing valve 7. The second interface of the second reversing valve 7 is communicated with the water replenishing pipe 72. The third interface of the second reversing valve 7 is communicated with the normal temperature water outlet pipe 73. The first interface of the second reversing valve 7 can be selectively communicated with the second interface or the third interface of the second reversing valve 7.

[0099] When water replenishment to the heat preservation tank 2 is required, the first interface of the second reversing valve 7 is communicated with the second interface, and the normal temperature water delivery pipe 71 is communicated with the heat preservation tank 2 to facilitate water replenishment to the heat preservation tank 2. When normal temperature water is to be discharged, the first interface of the second reversing valve 7 is communicated with the third interface, and the normal temperature water delivery pipe 71 is communicated with the water outlet member 4 to facilitate the user to access normal temperature water.

[0100] It should be noted that although the present utility model takes a pipeline machine as an example to introduce the water purification equipment of the present utility model, however, this is not restrictive. The specific water circuit of the water purification equipment of the present utility model is also applicable to other types of water purification equipment, and so on. Such flexible adjustments and changes do not deviate from the principle and scope of the present utility model and should all be included in the protection scope of the present utility model.

[0101] So far, the technical solutions of the present utility model have been described in conjunction with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present utility model is obviously not limited to these specific embodiments. Without departing from the principle of the present utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present utility model.
