Description

Technical Field

[0001] This utility model relates to the field of water purifiers, and in particular to a water system and a water purifier including the same. Background Technology

[0002] To prevent overflow caused by the failure of the liquid level control system, most water purifiers equipped with hot water tanks currently have an overflow protection mechanism. When the water level exceeds the limit, this mechanism will discharge the excess high-temperature hot water (usually >60℃) directly into the equipment's regular drainage system through the overflow pipe, and eventually into the external sewer or wastewater container.

[0003] However, directly introducing high-temperature overflow water into conventional drainage pipes poses significant risks. The primary hazard lies in the damage to the pipe materials. Equipment widely uses PVC and PP plastic drainage pipes or fittings, whose temperature resistance limit is typically only about 60°C. Continuous contact with overflow water far exceeding this limit will cause irreversible softening, deformation, and even localized melting of the pipes, severely weakening their structural strength and sealing. This easily leads to leaks at connections or pipe ruptures, causing water leakage accidents inside the equipment or in the installation environment, and accelerating pipe aging and embrittlement, shortening their lifespan. Secondly, leaked high-temperature water can soak electronic components in the equipment or surrounding property, posing risks of electrical short circuits, electric shock, and property damage. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects in the prior art that directly discharge the overflow water from the hot water tank of the water purifier will cause damage such as softening and deformation of the pipes, and to provide a water system and a water purifier including the system.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] This utility model discloses a water system, which includes a room temperature water tank and a hot water tank. The top of the hot water tank is provided with a first connecting port, which is located above the preset maximum water level of the hot water tank. The top of the room temperature water tank is provided with a second connecting port, which is connected to the first connecting port and the second connecting port. The top of the room temperature water tank is provided with an overflow prevention drain, which is located above the preset maximum water level of the room temperature water tank, and the overflow prevention drain is connected to an external drainage device.

[0007] In this solution, the water system, through the aforementioned configuration, connects a hot water tank to a room temperature water tank. If the hot water tank overflows, the overflow will not be discharged directly but will instead flow into the room temperature water tank through the first connection port. The room temperature water tank will then cool the hot water tank. If the room temperature water tank overflows again due to the inflow of overflow from the hot water tank, the overflow will be discharged through the overflow drain. This ensures proper handling of the hot water tank overflow, thereby reducing damage to the pipes caused by directly discharging hot water overflow and minimizing the risk of overflow outside the water system causing damage to the user's living space.

[0008] Preferably, the water system further includes a control element, a first water level probe is provided in the hot water tank, the first water level probe is electrically connected to the control element, the first water level probe is used to detect the preset maximum water level of the hot water tank, the control element is used to process the electrical signal fed back by the first water level probe and control the water inlet of the hot water tank, and the height of the first connection port is not lower than the height of the first water level probe.

[0009] In this solution, a first water level probe and control element are set up to detect the water level in the hot water tank in real time and stop the water inlet in time when the preset maximum water level is reached, thereby minimizing the possibility of the hot water tank overflowing. The overflow water from the hot water tank into the room temperature water tank serves as a remedial measure when the water level control fails, thereby improving the safety of the water system operation.

[0010] Preferably, a second water level probe is provided inside the ambient temperature water tank. The second water level probe is electrically connected to the control element. The second water level probe is used to detect the preset maximum water level of the ambient temperature water tank. The control element is also used to process the electrical signal fed back by the second water level probe and control the water inlet of the ambient temperature water tank. The height of the overflow outlet is not lower than the height of the second water level probe.

[0011] In this solution, a second water level probe is set up to detect the water level of the ambient temperature water tank in real time. The control unit stops water intake in time when the ambient temperature water tank reaches the preset maximum water level, thereby minimizing the possibility of water overflow from the hot water tank. The overflow water from the ambient temperature water tank is then discharged through the overflow drain as a remedial measure in case of water level control failure, further improving the safety of the water system operation.

[0012] Preferably, the second water level probe is located on the side of the ambient temperature water tank away from the second connection port.

[0013] In this solution, since the hot water overflowing from the second connection port is at a high temperature and contains a large amount of water vapor, if the second water level probe is too close to the second connection port, it may cause the second water level probe warning to be triggered erroneously. Setting the second water level probe away from the second connection port will minimize the occurrence of false triggers, thereby further improving the stability of the water system operation.

[0014] Preferably, the first connection port is located on the upper surface of the top of the hot water tank, and the second connection port is located on the upper surface of the top of the room temperature water tank.

[0015] In this design, the first and second connecting ports are respectively located on the upper surfaces of the hot water tank and the ambient temperature water tank. This ensures that when the water level reaches the highest point of the tank, hot water overflows from the top openings without any dead zones. In contrast, openings in other locations, such as on the sides, may result in an actual overflow level lower than the design value if there are errors in the installation height or if the tank is tilted, thus failing to achieve precise overflow prevention.

[0016] Preferably, the water system further includes a connecting pipe, one end of which is connected to the first connecting port, and the other end of which is connected to the second connecting port.

[0017] In this solution, different water system layouts have different requirements. By connecting the first and second connecting ports with connecting pipes, different lengths of connecting pipes can be used to make the distance between the hot water tank and the room temperature water tank meet the needs of various layouts, thereby improving the applicability of the water system.

[0018] Preferably, the connecting pipe is a condenser pipe.

[0019] In this solution, the condenser can further cool the water overflowing from the hot water tank, thereby further reducing damage to the pipes during discharge.

[0020] Preferably, the height of the first connecting port is higher than the height of the overflow prevention drain.

[0021] In this solution, the above structure can prevent water from the room temperature water tank from flowing back into the hot water tank, thereby avoiding any impact on the water temperature in the hot water tank.

[0022] Preferably, the ambient temperature water tank further includes an overflow prevention float, which is used to block water inflow when the water level in the ambient temperature water tank is higher than a preset maximum water level; and / or, the hot water tank further includes an overflow prevention float, which is used to block water inflow when the water level in the hot water tank is higher than a preset maximum water level.

[0023] In this solution, an anti-overflow float is added as an extra anti-overflow measure to further reduce the possibility of water overflow from hot water tanks or room temperature water tanks.

[0024] This utility model also discloses a water purifier, which includes the water system described above.

[0025] In this solution, the water system, through the aforementioned configuration, connects a hot water tank to a room temperature water tank. If the hot water tank overflows, the overflow will not be discharged directly but will instead flow into the room temperature water tank through the first connection port. The room temperature water tank will then cool the hot water tank. If the room temperature water tank overflows again due to the inflow of overflow from the hot water tank, the overflow will be discharged through the overflow drain. This ensures proper handling of the hot water tank overflow, thereby reducing damage to the pipes caused by directly discharging hot water overflow and minimizing the risk of overflow outside the water system causing damage to the user's living space.

[0026] The positive and progressive effects of this utility model are as follows:

[0027] This utility model provides a water system and a water purifier including the same. Through the aforementioned configuration, a hot water tank is connected to a room temperature water tank. If the hot water tank overflows, the overflow will not be directly discharged but will instead flow into the room temperature water tank through a first connecting port. The room temperature water tank will then cool the hot water tank. If the room temperature water tank overflows again due to the inflow of overflow from the hot water tank, the overflow will be discharged through an overflow prevention drain. This ensures proper handling of the hot water tank overflow, thereby reducing damage to the pipes caused by directly discharging the overflow and minimizing the risk of damage to the user's living space caused by overflow outside the water system.

[0045] Overflow Float 13 Detailed Implementation

[0046] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0047] like Figures 1 to 4 As shown, this embodiment provides a water system, which includes a normal temperature water tank 1 and a hot water tank 2. The hot water tank 2 includes a first top plate 3 located on the upper surface of the top. A first connecting port 4 is provided on the first top plate 3. The first connecting port 4 is located above the preset maximum water level of the hot water tank 2. The preset maximum water level of the hot water tank 2 is the safe water storage limit height set when designing the hot water tank 2.

[0048] like Figure 2 As shown, the ambient temperature water tank 1 includes a second top plate 5 and a side plate 6 located on the upper surface of the top. A second connecting port 7 is provided on the second top plate 5, and a first connecting port 4 connects to the second connecting port 7. An overflow drain 8 is provided on the upper part of the side plate 6 of the ambient temperature water tank 1. The overflow drain 8 is located above the preset maximum water level of the ambient temperature water tank 1, which is the safe water storage limit height set during the design of the ambient temperature water tank 1. The overflow drain 8 connects to an external drainage device. By placing the first connecting port 4 and the second connecting port 7 on the upper surfaces of the hot water tank 2 and the ambient temperature water tank 1 respectively, hot water can overflow from the top opening without any dead angle when the water level reaches the highest point of the tank. Compared to openings in other locations such as the side, if there are errors in the installation height, or if the water tank is tilted, the actual overflow water level may be lower than the design value, making precise overflow prevention impossible.

[0049] Thus, with the above-described configuration, the hot water tank 2 is connected to the ambient temperature water tank 1. If the hot water tank 2 overflows, the overflow will not be discharged directly but will instead enter the ambient temperature water tank 1 through the first connecting port 4. The ambient temperature water tank 1 will then cool the hot water tank 2. If the ambient temperature water tank 1 overflows again due to the inflow of overflow from the hot water tank 2, the overflow will be discharged through the overflow drain port 8. Figure 3 As shown, the arrow points to the path of the hot water overflow. This ensures that the overflow from hot water tank 2 is properly handled, thereby reducing the damage to the pipes caused by directly discharging the hot water overflow, and also reducing the risk of overflowing outside the water system and causing damage to the user's living space.

[0050] In this embodiment, as Figure 1 and Figure 2 As shown, the water system also includes a connecting pipe 9. The first connecting port 4 and the second connecting port 7 are connected such that one end of the connecting pipe 9 is connected to the first connecting port 4, and the other end of the connecting pipe 9 is connected to the second connecting port 7. Since different water systems have different layout requirements, connecting the first connecting port 4 and the second connecting port 7 through the connecting pipe 9 allows for the use of connecting pipes 9 of different lengths to meet the needs of various layouts, thereby improving the applicability of the water system.

[0051] Furthermore, the connecting pipe 9 is a condenser pipe. The condenser pipe can further cool the water overflowing from the hot water tank 2, thereby further reducing damage to the pipes during discharge.

[0052] Specifically, the water system also includes control elements 10, such as... Figure 4 As shown, a first water level probe 11 is installed inside the hot water tank 2. The first water level probe 11 is electrically connected to the control element 10. The first water level probe 11 is used to detect the preset maximum water level of the hot water tank 2. The control element 10 is used to process the electrical signal fed back by the first water level probe 11 and control the water to enter the hot water tank 2. The height of the first connecting port 4 is not lower than the height of the first water level probe 11.

[0053] Thus, by setting a first water level probe 11 and a control element 10 to detect the water level of the hot water tank 2 in real time and stop the water intake in time when the preset maximum water level is reached, the possibility of the hot water tank 2 overflowing is minimized, and the water overflowing from the hot water tank 2 into the room temperature water tank 1 is used as a remedial measure when the water level control fails, thereby improving the safety of the water system operation.

[0054] In this embodiment, one end of the first water level probe 11 is connected to the inner wall of the first top plate 3 of the hot water tank 2, and the other end extends into the hot water tank 2. The height of the first connecting port 4 is not lower than the height of the first water level probe 11, which means that the setting height of the first connecting port 4 is higher than or equal to the height of the end of the first water level probe 11 extending into the tank.

[0055] Furthermore, such as Figure 4 As shown, a second water level probe 12 is installed in the room temperature water tank 1. The second water level probe 12 is electrically connected to the control element 10. The second water level probe 12 is used to detect the preset maximum water level of the room temperature water tank 1. The control element 10 is also used to process the electrical signal fed back by the second water level probe 12 and control the water inlet of the room temperature water tank 1. The height of the overflow outlet 8 is not lower than the height of the second water level probe 12.

[0056] Thus, by setting a second water level probe 12 to detect the water level of the ambient temperature water tank 1 in real time, the control unit will stop the water intake in time when the ambient temperature water tank 1 reaches the preset maximum water level, thereby minimizing the possibility of the hot water tank 2 overflowing. The overflow water from the ambient temperature water tank 1 will then be discharged through the overflow drain 8 as a remedial measure in case of water level control failure, further improving the safety of the water system operation.

[0057] In this embodiment, one end of the second water level probe 12 is connected to the inner wall of the second top plate 5 of the hot water tank 2, and the other end extends into the room temperature water tank 1. The height of the overflow drain 8 is not lower than the height of the second water level probe 12, which means that the height of the lower edge of the overflow drain 8 is higher than or equal to the height of the end of the second water level probe 12 extending into the tank.

[0058] Furthermore, the second water level probe 12 is located on the side of the ambient temperature water tank 1 away from the second connecting port 7.

[0059] Thus, since the hot water overflowing from the second connection port 7 has a high temperature and a large amount of water vapor, if the second water level probe 12 is too close to the second connection port 7, it may cause the second water level probe 12 to be triggered incorrectly. Setting the second water level probe 12 away from the second connection port 7 will minimize the occurrence of accidental triggering, thereby further improving the stability of the water system operation.

[0060] In this embodiment, when the connecting pipe 9 is a condenser pipe, the generation of water vapor can be reduced by cooling the pipe, thereby further reducing the possibility of accidental contact.

[0061] Furthermore, the height of the first connecting port 4 is higher than the height of the overflow drainage port 8.

[0062] Thus, the above structure can prevent water from the room temperature water tank 1 from flowing back into the hot water tank 2, thereby avoiding any impact on the water temperature in the hot water tank 2.

[0063] Specifically, such as Figure 4 As shown, the ambient temperature water tank 1 also includes an overflow prevention float 13, which is used to block water inflow when the water level in the ambient temperature water tank 1 is higher than the preset maximum water level; or, the hot water tank 2 also includes an overflow prevention float 13, which is used to block water inflow when the water level in the hot water tank 2 is higher than the preset maximum water level; or, both the ambient temperature water tank 1 and the hot water tank 2 are equipped with overflow prevention floats 13. The overflow prevention float 13 is prior art and will not be discussed further in this patent. Generally speaking, the overflow prevention float 13 is a mechanical anti-overflow device that automatically controls the water level in the tank based on the principle of buoyancy. Its core function is to automatically cut off water inflow when the water level reaches a preset height to prevent overflow.

[0064] Thus, by using the overflow prevention float 13 as an additional overflow prevention measure, the possibility of overflow from the hot water tank 2 or the room temperature water tank 1 is further reduced.

[0065] This embodiment also provides a water purifier, which includes the water system described above.

[0066] Thus, through the above-described configuration, the hot water tank 2 is connected to the ambient temperature water tank 1. If the hot water tank 2 overflows, the overflow will not be discharged directly but will instead enter the ambient temperature water tank 1 through the first connecting port 4. The ambient temperature water tank 1 will then cool the hot water tank 2. If the ambient temperature water tank 1 overflows again due to the inflow of overflow from the hot water tank 2, the overflow will be discharged through the overflow drain port 8. This ensures that the overflow from the hot water tank 2 is properly handled, thereby reducing the damage to the pipes caused by directly discharging the overflow and also reducing the risk of overflow outside the water system causing damage to the user's living space.
