Detailed Implementation

[0034] The present disclosure is further illustrated below by way of embodiments, but the present disclosure is not limited to the scope of the embodiments described herein.

[0035] Example 1

[0036] This embodiment provides a heating container 10, such as... Figure 1 As shown, it includes a housing 16, a sterilizer 13, a heating element 12, and a stirring device 11;

[0037] The housing 16 is hollow and is used to contain liquid;

[0038] The sterilizer 13 extends into the interior of the housing 16 and is used to sterilize the liquid inside the housing 16;

[0039] The stirring device 11 is disposed at the bottom of the housing 16 and is used to stir the liquid inside the housing 16;

[0040] The heating element 12 is disposed between the sterilizer 13 and the agitator 11 and is used to heat the liquid inside the shell 16.

[0041] In this solution, the stirring device 11 at the bottom of the heating container is used to create convection between the liquid below the heating body 12 and the liquid above the heating body 12, so that the liquid below the heating body 12 is not blocked by the heating body 12, which would cause dead corners in the sterilization range of the sterilizer. Especially when the liquid in the heating container 10 is heated to 45°C and kept warm, the liquid in the shell 16 is fully heated and sterilized.

[0042] In one possible manner, one end of the sterilizer 13 extends from the top of the housing 16 into the interior of the housing 16, and the sterilizer 13 is sealed to the top of the housing 16.

[0043] In this design, the sterilizer 13 extends into the housing 16 through an opening at the top of the housing 16. The sterilizer 13 is capable of emitting light for sterilizing the liquid inside the housing. The sterilizer 13 can be a mercury lamp or an ultraviolet lamp.

[0044] In one possible arrangement, the inlet 17 of the housing is located at the lower part of the housing, and the outlet 18 of the housing 16 is located at the upper part of the housing 16.

[0045] In this scheme, water enters through the water inlet 17 at the bottom of the housing 16, and after being heated by the heater 12, the water is exposed to the irradiation range of the sterilizer 13 for sterilization. The overall liquid level inside the housing 16 is controlled by the water outlet 18 located at the top of the housing 16, so that the liquid level inside the housing 16 covers the sterilizer 13 and forms a water channel.

[0046] In one possible implementation, the agitation device 11 includes an impeller 15 disposed within the housing 16;

[0047] A drive motor 19 is disposed on the bottom outer side of the housing 16, and the output shaft of the drive motor 19 extends into the housing 16 and is connected to the impeller 15 to drive the impeller 15 to rotate.

[0048] The output shaft is sealed to the housing 16.

[0049] In this design, the impeller 15 is positioned facing the top of the housing 16, and a dynamic seal is formed between the output shaft of the drive motor 19 and the bottom of the housing 16, driving the impeller 15 to rotate via the output shaft. In one embodiment, based on the positions of the heater 12 and the sterilizer 13 within the housing 16, the impeller 15 is tilted to guide the liquid below the heater 12 to flow upwards from the gap between the heater 12 and the housing 16. The impeller 15 can be connected to the output shaft of the drive motor 19 via a coupling to improve the liquid flow efficiency.

[0050] In one possible implementation, the sterilizer 13 includes a transparent cover and a light-emitting unit 14;

[0051] The light-emitting unit is disposed inside the transparent cover.

[0052] In this design, the sterilizer 13 sterilizes the liquid inside the housing using ultraviolet light. The light-emitting unit 14 is cylindrical, and its structure can match the structure of the housing. If the housing 16 is a polygonal cylindrical body, then the light-emitting unit 14 is set as a cylindrical body with equilateral sides of the housing 16; or, the light-emitting unit 14 is set as a cylinder. A transparent cover covers the light-emitting unit 14, and the shape of the transparent cover matches the shape of the light-emitting unit 14 to increase the refractive index of the light-emitting unit 14 and improve the sterilization range.

[0053] As one possible approach, the light-emitting unit 14 is an LED array.

[0054] In this scheme, the LED array is arranged around the circumference of the light-emitting unit 14, and adjacent rows of the LED array are arranged at equal intervals, and / or the LEDs in the same column of adjacent rows are arranged alternately; in one embodiment, the light-emitting unit 14 includes a top surface facing the bottom of the housing, and corresponding LED beads are arranged on the top surface to improve the coverage of ultraviolet light and avoid sterilization dead corners.

[0055] The heating container provided in this embodiment improves the sterilization efficiency and range of the heating container by setting an agitation device at the bottom of the heating container, thereby exposing the liquid at the bottom of the heating container to the sterilization range of the sterilizer and ensuring the water quality and safety of the water purifier.

[0056] Example 2

[0057] This embodiment provides a waterway structure, such as... Figure 2 and 3 As shown, it includes the heating container described in Example 1.

[0058] As one possible approach, it also includes a first water path connection unit 100, a filter unit 200, a second water path connection unit 300, and a water storage tank 410;

[0059] One end of the first water circuit connection unit 100 is connected to the water inlet water circuit, and the other end is connected to the water inlet of the filter unit 200. One end of the second water circuit connection unit 300 is connected to the water outlet of the filter unit 200, and the other end is connected to the water inlet of the water storage tank 410.

[0060] The first water connection unit 100 includes a first water quality detection element 110 and a first drain outlet. The first water quality detection element 110 is used to detect the quality of the incoming water.

[0061] The filtration unit 200 is used to remove impurities from the incoming water flow;

[0062] The second water connection unit 300 includes a second water quality detection element 310 and a second drain outlet. The second water quality detection element 310 is used to detect the water quality after filtration.

[0063] The outlet of the water storage tank 410 is connected to the inlet 17 of the heating container 10, and is used to store filtered clean water and provide water for the heating container 10.

[0064] In this scheme, the water circuit structure filters the incoming water through the first water circuit connection unit 100, the second water circuit connection unit 300 and the filter unit 200, and forms a flushing pipeline for the filter unit 200. The water storage tank 410 and the heating container 10 serve as the water production unit 400 to improve the water quality in the water production unit 400.

[0065] As one possible implementation, a water inlet pipe is provided between the water storage tank 410 and the heating container 10, and a one-way valve 428 is provided on the water inlet pipe; and / or,

[0066] An exhaust pipe 416 is provided between the water storage tank 410 and the heating container 10, and a damper 429 is provided on the exhaust pipe 416.

[0067] In this scheme, a gravity check valve 428 is preferably used. By setting the gravity check valve 428, water in the heating container 10 is prevented from flowing back into the water storage tank 4, and the damper 249 reduces the exhaust pressure of the heating container 10 to the water storage tank 410, thereby ensuring the stability of the heating container 10.

[0068] The working principle of the waterway structure in this embodiment will be explained in detail below through specific implementation methods:

[0069] The water circuit structure provided in this embodiment has the following operating modes: drainage mode, flushing mode, water production and flushing mode, water production mode, full water flushing mode, heating mode, overflow mode, water outlet mode, and emptying mode. Specifically:

[0070] In the drainage mode, after water and electricity are supplied, the pH probe, which serves as the first water quality detection device 110, monitors the water quality at the inlet in real time. If the inlet water quality meets the preset pH value, the first water supply control valve 112 is opened; otherwise, the first drainage control valve 111 is opened and the first water supply control valve 112 is closed, thus entering the drainage mode to drain the acidic or alkaline water in the inlet pipe until the inlet water quality meets the preset pH value.

[0071] In the flushing mode, when the incoming water quality meets the preset pH value, the filter unit 200 enters the flushing mode. This mode requires manual operation to enter. After entering the flushing mode, the first water supply control valve 112 opens, the first drain control valve 111 closes, the water pump 240 opens, the third drain control valve 221 opens, and the second drain control valve 311 and the second water supply control valve 320 close. The duration can be set according to the actual situation.

[0072] In the water production and flushing mode, after the filter unit 200 has finished flushing, the system enters the water production and flushing mode. Specifically, the first water supply control valve 112 is open, the first drain control valve 111 is closed, the water pump 240 is on, the third drain control valve 221 is closed, the second drain control valve 311 is open, and the second water supply control valve 320 is closed. At this time, the COD probe, which serves as the second water quality detection element 310, monitors the COD value of the filtered influent in real time. If the COD value of the filtered influent is less than or equal to 2 mg / L, the water production and flushing mode stops; otherwise, water production and flushing continue.

[0073] In water production mode, after completing the water production and flushing mode, the system enters water production mode. During this time, the pH probe continuously monitors the pH value in real time. Water production mode is only activated when the pH value falls below the preset value. Even after entering water production mode, if the incoming water quality does not meet the preset pH value, the system will immediately switch to drainage mode. When water production mode is activated, the first water supply control valve 112 opens, the first drainage control valve 111 closes, the water pump 240 starts, the third drainage control valve 221 closes, the second drainage control valve 311 closes, and the second water supply control valve 320 opens. At this time, the second level float 413 in the water storage tank 410 monitors the liquid level in real time. When the liquid level reaches the middle level of the second level float 413, and the level probe 427 in the heating water tank 420 also detects the liquid level, the heater 423 is activated, and water production continues until the second level float 413 detects that the water storage tank 410 is at a high level, at which point water production stops.

[0074] In the full-water flushing mode, when the second liquid level float 413 detects that the water tank 410 is at a high liquid level, the filter unit 200 is flushed once. That is, the first water supply control valve 112 is opened, the first drain control valve 111 is closed, the water pump 240 is turned on, the third drain control valve 221 is opened, and the second drain control valve 311 and the second water supply control valve 320 are closed. The full-water flushing mode stops after the preset flushing time is completed.

[0075] In heating mode, when the second level float 413 in the water storage tank 410 detects that the water storage tank 410 is at the middle level, and at the same time the level probe 427 in the heating water tank 420 detects the level, the heater 423 is turned on until the NTC temperature sensor 421 detects that the water temperature has reached the preset temperature and then stops heating. When the temperature is below 92℃, and at the same time the second level float 4131 detects that the water storage tank 410 is at the middle level, and at the same time the level probe 427 in the heating water tank 420 detects the level, the electric heater 423 is turned on. This cycle continues.

[0076] In overflow mode, when the first level float 412 in the water tank detects the water level in the storage tank 410, it indicates that water is continuously flowing into the water tank and the second level float 413 is malfunctioning. At this time, a fault reminder notification is sent.

[0077] In the hot water outlet mode, when the hot water outlet valve 425 is open, hot drinking water flows out. The preset hot water outlet valve 425 can remain open for 60 seconds at a time. If no signal to close the hot water outlet valve 425 is given after 60 seconds, it will be forcibly closed. To reopen it, another opening command is required. The cold water outlet method is the same as for hot water.

[0078] In the evacuation mode, if the hot water outlet valve 425 or the cold water outlet valve fails to open within the preset time, and the water level in the storage tank 410 is higher than the low level, the fourth drain control valve 424 and the first drain control valve 111 will open. The evacuation duration can be preset. After evacuation is complete, the system enters the water production mode. Before entering the water production mode, the system must monitor the data returned by the pH probe in real time. Only if the data meets the system's preset value can the system enter the water production mode; otherwise, it will enter the drain mode.

[0079] Example 3

[0080] This embodiment provides a water purifier, which includes the water circuit structure described in Embodiment 2.

[0081] The water purifier provided in this embodiment detects the quality of the incoming water and the filtered water through the first water path connection unit 100 and the second water path connection unit 300 between the water inlet, the filter unit 200 and the water production unit 400. It promptly discharges incoming water containing harmful substances to prevent harmful substances from damaging the filter unit 200 and the water production unit 400, thus ensuring the filtration capacity of the water purifier. It also improves the sterilization efficiency of the medium-temperature water in the container by heating the container, thereby improving the drinking water quality of the water purifier.
