Description

[Technical Field]

[0001] This application relates to the field of water purifier technology, and more particularly to a water purifier with a built-in cool boiled water dispenser. [Background Technology]

[0002] Traditional water purifiers can only dispense unheated room temperature water and heated hot water. While heated hot water is healthy, it cannot be consumed immediately. Therefore, existing water purifiers use a cooling module to exchange heat with the hot water to achieve a cooling effect, thus obtaining healthy, room-temperature boiled water. However, the additional cooling module has high energy consumption and cost. Moreover, if a low-cost, energy-efficient cooling module is used, its heat exchange efficiency for hot water will be greatly reduced. Therefore, there is a need for a water purifier that is both low-cost and has high heat exchange efficiency. [Summary of the Invention]

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0025] like Figure 1-4 As shown, a water purifier with cooled boiled water includes a body 1. The body 1 includes a heating module 8, a filtration module 3, and a cooling module 4 connected to the heating module 8. The cooling module 4 includes a cooling water tank 41. The cooling water tank 41 has a high-level water outlet 42 and a low-level water outlet 43 located below the high-level water outlet 42. Below the low-level water outlet 43 is an inlet 44 for connecting the wastewater outlet of the cooling water tank 41 and the filtration module 3. The low-level water outlet 43 is connected to a rapid cooling control module 5 to control the simultaneous discharge of water from the low-level water outlet 43 and the high-level water outlet 42, and simultaneously control the filtration module 3 to drain a large amount of water through the inlet 44 into the cooling water tank 41 to accelerate the cooling of the hot water produced by the heating module 8.

[0026] In this embodiment, the present invention achieves energy-saving and environmental protection effects by introducing the wastewater after use of the filtration module 3 into the cooling water tank 41 of the cooling module 4, thereby reducing costs. Moreover, when it is necessary to accelerate the cooling of hot water, that is, when the temperature of the cooled boiled water outlet is detected to be too high, the rapid cooling control module 5 will control the low-level outlet 43 to open, so that it can discharge water simultaneously with the high-level outlet 42, increasing the drainage volume. At the same time, the filtration module 3 discharges a large amount of wastewater into the cooling water tank 41 through the inlet 44 connected to the filtration module 3, increasing the water intake volume, so as to continuously drain the relatively high-temperature wastewater in the cooling water tank 41 that has exchanged heat with the cooling pipe, thereby accelerating cooling, improving the heat exchange efficiency of the machine, and thus regulating the temperature of the cooled boiled water, keeping the temperature of the cooled boiled water flowing out of the machine stable, improving the user experience, and solving the problems of high energy consumption, high cost or low heat exchange efficiency of existing water purifiers.

[0027] In this embodiment, the high-level outlet 42 is always open and is located at a high position in the cooling water tank 41. The inlet 43, located at a very low position in the cooling water tank 41, continuously discharges wastewater from the filter module 3 into the cooling water tank 41. The wastewater continuously accumulates in the cooling water tank 41 until the water level reaches the high-level outlet 42, and then the wastewater in the cooling water tank 41 is discharged through the high-level outlet 42.

[0028] Preferably, a wastewater valve 103 is provided between the wastewater outlet and the inlet 44 of the filter module 3 to control the discharge of wastewater into the cooling water tank 41. Both the pipe 2 connecting the low outlet 43 and the pipe 2 connecting the high outlet 42 discharge wastewater to the wastewater outlet. The pipe 2 connecting the wastewater outlet and the inlet 44 of the filter module 3 is provided with a wastewater valve 103 to control the discharge of wastewater into the cooling water tank 41. When the wastewater valve 103 is opened, the wastewater generated by the filter module 3 can be discharged into the cooling water tank 41. In normal working mode, the wastewater valve 103 first discharges part of the wastewater into the cooling water tank 41 and then closes. When the temperature of the cooled boiled water is detected to be too high, the rapid cooling control module 5 sends an electrical signal to the wastewater valve 103 to open it, thereby discharging a large amount of wastewater into the cooling water tank 41.

[0029] Furthermore, the body 1 also includes a body water inlet module 6 connected to the filter module 3 and a body water outlet module 7 connected to the cooling module 4. The heating module 8, the filter module 3, the cooling module 4, the body water inlet module 6 and the body water outlet module 7 are interconnected by a pipe 2. The heating module 8 is provided with a first heating water inlet 81 connected to the filter module 3 and a first heating water outlet 82 connected to the cooling module 4.

[0030] In this embodiment, the water inlet module 6 includes a water inlet nozzle connected to the filter module 3 via a pipe 2, the water outlet module 7 includes a water outlet nozzle connected to the cooling module 4 via a pipe 2, the heating module 8 includes an instant heating module for heating room temperature water to boiling water, a first flow control pump for controlling the output water flow rate is provided between the filter module 3 and the heating module 8, a flow meter for displaying the water flow rate is provided between the first flow control pump and the heating module 8, and the cooling module 4 has a tortuous cooling pipe connected to the first heating outlet 82 for receiving boiling water to be cooled.

[0031] Furthermore, the rapid cooling control module 5 includes a control unit 51, a low-position drain valve 52 electrically connected to the control unit 51, and a temperature sensor 53 electrically connected to the control unit 51. The low-position drain valve 52 is located on the pipe 2 connected to the low-position water outlet 43, and the temperature sensor 53 is located on the pipe 2 connecting the body water outlet module 7 and the cooling module 4.

[0032] In this embodiment, as Figure 4As shown, a temperature sensor 53 for detecting the temperature of the cooled boiled water is provided on the pipe 2 connecting the water outlet module 7 and the cooling module 4. When the temperature sensor 53 detects that the temperature of the cooled boiled water is too high, it sends an electrical signal to the control unit 51. The control unit 51 then sends a signal to the low-level drain valve 52, causing the low-level drain valve 52 to open. The low-level drain valve 43, which is located between the inlet 44 and the high-level outlet 42 and is at a lower position in the cooling water tank 41, will discharge the wastewater in the cooling water tank 41 at the same time as the high-level outlet 42. At the same time, the control unit 51 sends an electrical signal to the filter module, causing it to enter the flushing mode. When the filter module enters the flushing mode, it will discharge a large amount of wastewater, so that a large amount of wastewater is discharged into the cooling water tank 41 through the inlet, almost keeping the wastewater level in the cooling water tank 41 at the water level that can be discharged through the high-level outlet 42.

[0033] Furthermore, a first control valve 101 is provided between the filter module 3 and the body water outlet module 7. The first control valve 101 is provided with a normal temperature water inlet 1011 connected to the filter module 3, a second heating water inlet 1012 connected to the cooling module 4, and a first body water outlet 1013 connected to the body water outlet module 7.

[0034] In this embodiment, the machine body 1 is divided into a normal temperature branch and a water flow branch that needs to be heated through the first control valve 101. The normal temperature branch includes the machine body water inlet module 6, the filter module, the normal temperature water inlet 1011 of the first control valve 101, the first machine body water outlet 1013 of the first control valve 101, and the machine body water outlet module 7. The water flowing out of the normal temperature branch is filtered normal temperature water. The water flow branch that needs to be heated includes the machine body water inlet module 6, the filter module, the second heating water inlet 1012 of the first control valve 101, the first machine body water outlet 1013 of the first control valve 101, and the first heating water inlet 81 of the heating module 8, etc.

[0036] In this embodiment, the cooled boiled water tank 9 is used to store cooled boiled water, and the heating module 8 uses a 2100W, 10A instant heating pipe assembly, which can continuously produce water at a boiling rate of 400ml / min.

[0037] In another embodiment, the heating module 8 uses an instant heating pipe assembly with a working specification of 3300W and 16A, and the hot water boiling rate is 600ml / min. This setting allows for the continuous extraction of small amounts of cool boiled water even after the water in the cool boiled water tank is depleted, without the water tank remaining in the tank.

[0038] Furthermore, the cooled boiled water tank 9 is provided with a float switch system 91, which includes a low-level float 911 located at a lower position inside the cooled boiled water tank 9 and a high-level float 912 located at a higher position inside the cooled boiled water tank 9.

[0039] In this embodiment, the float switch system 91 is used to detect the water level in the cooled boiled water tank 9. When the low water level float 911 and the high water level float 912 are triggered simultaneously, the control module inside the machine sends a signal to stop cooling the hot water to the module that controls the hot water to flow into the cooling module 3.

[0040] Preferably, the cooled boiled water tank 9 is equipped with a sterilization lamp on its inner side to facilitate the sterilization of the cooled boiled water.

[0041] Furthermore, a second control valve 102 is provided between the heating module 8 and the body water outlet module 7.

The cool water branch consists of the machine body water inlet module 6, the filter module, the second heating water inlet 1012 of the first control valve 101, the first machine body water outlet 1013 of the first control valve 101, the heating module 8, the cooling module, the second heating water inlet 1012 of the first control valve 101, the first machine body water outlet 1013 of the first control valve 101, and the machine body water outlet module 7.

[0043] Preferably, a second flow control pump is provided between the cooled boiled water tank 9 and the second control valve 102.

[0044] Furthermore, the filtration module 3 includes a pre-composite filter element 31 connected to the water inlet module 6 of the machine body, a reverse osmosis filter element 32 connected to the pre-composite filter element 31, and a post-activated osmosis filter element 33 connected to the reverse osmosis filter element 32. The outlet end of the reverse osmosis filter element 32 serves as the wastewater outlet end of the filtration module 3 and is connected to the cooling module 4. The outlet end of the post-activated osmosis filter element 33 is connected to the cooling inlet end of the cooling module 4.

[0045] In this embodiment, the pre-filter composite element 31, the reverse osmosis filter element 32, and the post-activated osmosis filter element 33 make the filtered water purer and improve the user's drinking water safety. A pressure reducing valve is provided between the water inlet module 6 and the pre-filter composite element 31 to facilitate filtration by the pre-filter composite element 31.

[0046] Furthermore, a booster pump 34 is provided between the pre-filter composite element 31 and the reverse osmosis filter element 32. The inlet end of the booster pump 34 is connected to the outlet end of the pre-filter composite element 31, and the outlet end of the booster pump 34 is connected to the inlet end of the reverse osmosis filter element 32.

[0047] In this embodiment, the booster pump is used to pressurize the water filtered by the pre-filter composite cartridge 31, thereby improving the smoothness of the water flow in the subsequent pipeline.

[0048] Furthermore, a pressure relief valve 35 is provided between the inlet end of the booster pump 34 and the outlet end of the post-activated permeation filter 33.

[0049] In this embodiment, the water filtered by the pre-filter composite filter 31 can be directly sent to the heating module 8 for heating. A one-way valve is provided between the post-activated permeation filter 33 and the pressure relief valve 35 to prevent backflow of water after the pressure relief valve 35.

[0050] Preferably, a first flow control pump 104 is provided between the heating module 8 and the filter module 3, and a flow meter 105 is provided between the first flow control pump 104 and the first heating water inlet 81.

[0051] In this embodiment, the first flow control pump 104 can be used to control the water flow between the heating module 8 and the filter module 3, while the flow meter 105 is used to display the current water flow between the heating module 8 and the filter module 3, so that the user can control the first flow control pump 104 according to the size displayed by the flow meter 105.

[0052] Preferably, a second flow control pump 106 is provided between the second heating water inlet 1012 and the cooling module 4.

[0053] In this embodiment, the second flow control pump 106 can be used to control the water flow between the cooling module 4 and the first control valve 101.

[0054] The working principle of this invention is as follows:

[0055] This invention achieves energy conservation and environmental protection by directing the wastewater from the filtration module 3 into the cooling water tank 41 of the cooling module 4, thereby reducing costs. Furthermore, when faster cooling of hot water is needed, i.e., when the temperature at the cooled boiled water outlet is detected to be too high, the rapid cooling control module 5 controls the low-level outlet 43 to open, allowing it to flow out simultaneously with the high-level outlet 42, increasing the drainage volume. Simultaneously, the filtration module 3 discharges a large amount of wastewater into the cooling water tank 41 through its inlet 44, increasing the water intake and continuously removing the relatively high-temperature wastewater that has exchanged heat with the cooling pipes within the cooling water tank 41. This accelerates cooling, improves the heat exchange efficiency of the machine, and regulates the temperature of the cooled boiled water, ensuring a stable temperature as it flows out of the machine, enhancing the user experience. This solves the problems of high energy consumption, high cost, or low heat exchange efficiency in existing water purifiers.
