Description

Technical Field

[0001] The utility model relates to the technical field of water purification, in particular to a water purifier. Background Art

[0002] A water purifier, also known as a water purifier, is a water treatment device that filters and purifies water, removing floating debris, heavy metals, pathogens, and other foreign matter according to specific water usage requirements. The water purified by existing water purifiers is safe and can be directly consumed, providing significant convenience for people's lives.

[0003] Most water purifiers can only provide users with drinking water at room temperature. If hot water or ice water is required, the room temperature water needs to be processed again. Some water purifiers have heating and cooling functions. Heating generally uses a heating tube installed in the hot tank. The heating tube stops heating when the water in the hot tank reaches the target temperature. When the water temperature in the hot tank drops to a certain threshold, the heating tube starts heating again to achieve heat preservation. Refrigeration generally uses semiconductor refrigeration or compressor refrigeration. One side of the semiconductor refrigeration plate cools the water in the cold tank through conduction, and the other side of the semiconductor refrigeration plate heats the water, and the heat generated is discharged to the surrounding environment through a fan. Compressor refrigeration cools the water in the cold tank by circulating the refrigerant in the refrigeration system to evaporate and condense, and the heat generated is discharged to the surrounding environment through a fan.

[0004] In existing water purifiers, the cooling system and heating system are separate systems. The heat generated in the cooling system is discharged into the surrounding environment, resulting in energy waste. The heating system requires frequent activation of the heating pipe to achieve heat preservation, which consumes a lot of electricity. Utility Model Content

[0029] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0030] See also Figure 1 and Figure 2This embodiment provides a water purifier, including a housing 10, and a filter element 20, a cold water storage tank 30, a hot water storage tank 40, a refrigeration assembly 50, and a controller disposed within the housing 10. The water inlet end of the filter element 20 is connected to a raw water pipeline, and the water outlet end of the filter element 20 is connected to the water inlet end of the cold water storage tank 30 and the water inlet end of the hot water storage tank 40, respectively. The refrigeration assembly 50 has a cold end and a hot end. The cold end transfers cold energy to the cold water storage tank 30, and the hot end transfers heat to the hot water storage tank 40. The water outlet ends of the filter element 20, the cold water storage tank 30, and the hot water storage tank 40 are all connected to the water outlet end of the water purifier.

[0031] The water outlet of the filter element 20 flows out water at room temperature, the water outlet of the cold water storage tank 30 flows out water at a temperature lower than room temperature, and the water outlet of the hot water storage tank 40 flows out water at a temperature higher than room temperature. The specific temperature can be set according to actual needs. Optionally, the water purifier also includes a room temperature water tank, and the water outlet of the filter element 20 is connected to the room temperature water tank. Because it takes a certain amount of time for the filter element 20 to process the raw water, by providing a room temperature water tank, the pure water can be stored in advance, which effectively saves time and avoids the user from waiting for a long time when the pure water is needed.

[0032] The hot water tank 40 is provided with a heating pipe and a first temperature sensor. The heating pipe is used to heat the water in the hot water tank 40. The first temperature sensor is used to obtain the water temperature value in the hot water tank 40. The cold water tank 30 is provided with a second temperature sensor. The second temperature sensor is used to obtain the water temperature value in the cold water tank 30.

[0033] The refrigeration assembly 50 , the first temperature sensor and the second temperature sensor are all electrically connected to the controller. The controller can obtain the water temperature of the hot water storage tank 40 and the cold water storage tank 30 , and can also control the working status of the heating pipe and the refrigeration assembly 50 .

[0034] The water purifier also includes a heat conduction assembly 60, which includes a heat conduction pipe 61 and a fan 62 disposed within the heat conduction pipe 61. The fan 62 guides airflow along the heat conduction pipe 61 from the hot end to the hot water storage tank 40. The heat generated by the refrigeration assembly 50 during cooling can keep the water in the hot water storage tank 40 warm, eliminating the need for frequent heating. This improves the utilization rate of the refrigeration assembly 50, fully utilizes energy, and effectively saves energy.

[0035] Refrigeration assembly 50 can be either a semiconductor refrigeration assembly or a compressor refrigeration assembly. A semiconductor refrigeration assembly includes a semiconductor refrigeration sheet, which is a conventional structure used for heat transfer. When current flows through a thermocouple pair formed by connecting an N-type semiconductor material and a P-type semiconductor material, heat transfer occurs between the two ends. Heat is transferred from one end to the other, creating a temperature difference between the hot and cold ends. A compressor refrigeration assembly is a conventional structure used for heat transfer, achieving cooling through the evaporation and condensation of a refrigerant circulating in the refrigeration system, while also generating heat.

[0036] In this embodiment, both the cold end and the hot end of the refrigeration component 50 are utilized. The cold end is used to cool the water in the cold water storage tank 30, and the hot end is used to keep the water in the hot water storage tank 40 warm, thereby improving the utilization rate of the refrigeration component 50 and effectively saving energy.

[0037] The water in the cold water storage tank 30 is cooled by a cold end, and the cold end may have a cooling surface, and the cooling surface is in contact with the cold water storage tank 30. The cold energy is transferred by surface-to-surface contact to increase the contact area. Alternatively, the water purifier may further include a cooling element 70, one end of which is connected to the cold end, and the other end of which extends into the interior of the cold water storage tank 30. The cooling element 70 is in direct contact with the water, which facilitates the transfer of cold energy and increases the cooling rate. Exemplarily, the cooling element 70 includes a plurality of fins 71, and the fins 71 are located inside the cold water storage tank 30. The contact area with the water is increased, and the transfer efficiency is improved. In order to avoid the loss of cold energy, a cooling pipe 80 may be provided between the cold end and the cold water storage tank 30, and the cooling element 70 is located inside the cooling pipe 80.

[0038] The hot end is used to insulate the water in the hot water tank 40 because the temperature difference between the cold end and the hot end of the refrigeration assembly 50 is typically between 40°C and 65°C. While the hot end has some heat, it is insufficient to heat the water in the hot water tank 40 to a very high temperature. By installing a heating pipe in the hot water tank 40, the pure water in the hot water tank 40 can be quickly heated. Once the water in the hot water tank 40 reaches the target temperature, the heating pipe is turned off, and the hot end is used to insulate the water in the hot water tank 40, avoiding frequent activation of the heating pipe.

[0039] To transfer heat to the hot water tank 40, air flows along the heat-conducting pipe 61, which has an air inlet 611 and an air outlet 612. The hot end of the heat-conducting pipe 61 is located between the air inlet 611 and the fan 62, and the hot water tank 40 is located between the fan 62 and the air outlet 612. Driven by the fan 62, air enters the heat-conducting pipe 61 from the air inlet 611 and flows toward the air outlet 612. As the air flows through the hot end, it becomes a hot air flow. After flowing through the hot water tank 40, the hot air flow flows out of the air outlet 612. As the hot air flows through the hot water tank 40, it exchanges heat with the hot water tank 40, transferring heat to the hot water tank 40 and providing a certain degree of insulation.

[0040] In this embodiment, a plurality of air inlets 611 are provided, and the plurality of air inlets 611 are spaced apart around the circumference of the heat conducting pipe 61. This allows for uniform air intake around the circumference of the heat conducting pipe 61, increases the air intake area and gas flow rate, and improves heat exchange efficiency.

[0041] Furthermore, a filter is provided at the air inlet 611 to prevent foreign matter from entering the heat conducting pipe 61 , and the filter may be a filter net.

[0042] The heat transfer assembly 60 also includes a first damper 63, which is positioned between the fan 62 and the hot water tank 40. The first damper 63 can rotate between an open position and a closed position to open or close the air outlet 612. When the first damper 63 is in the open position, the air outlet 612 communicates with the air inlet 611. Driven by the fan 62, air flows from the air inlet 611 into the heat transfer conduit 61 and toward the air outlet 612, transferring heat to the hot water tank 40 during the flow. When the first damper 63 is in the closed position, the air outlet 612 is separated from the air inlet 611. Since the hot water tank 40 is located downstream of the first damper 63, heat cannot be transferred to the hot water tank 40.

[0043] The heat transfer assembly 60 also includes a stepper motor connected to the first damper 63 to drive the first damper 63 to rotate between an open position and a closed position. The heat transfer pipe 61 can be a circular tube, and the first damper 63 is in the shape of a circular plate. The first damper 63 is connected to the heat transfer pipe 61 via a support shaft, the axis of which extends radially along the heat transfer pipe 61.

[0044] The heat transfer pipe 61 also has an exhaust port 613, located downstream of the fan 62 along the airflow direction. The heat transfer assembly 60 also includes a second damper 64, which is disposed at the exhaust port 613 to open or close the exhaust port 613. When the exhaust port 613 is open, air can enter the heat transfer pipe 61 from the air inlet 611 and flow toward the exhaust port 613 under the action of the fan 62. When the exhaust port 613 is closed, air cannot flow out of the exhaust port 613. The second damper 64 can also be driven by a stepper motor, so that the first damper 63 and the second damper 64 move independently.

[0045] One axial end of the heat transfer pipe 61 is connected to the refrigeration assembly 50. An air inlet 611 can be provided along the circumference of the heat transfer pipe 61, and an air outlet 612 can be provided at the other axial end of the heat transfer pipe 61. An air outlet 613 can be provided alongside the air outlet 612, or alternatively, the air outlet 613 can be provided on the sidewall of the heat transfer pipe 61. The heat transfer pipe 61 can include a main pipe and two branch pipes. The fan 62 is provided within the main pipe. The first damper 63 and the hot water storage tank 40 are provided on one branch pipe, and the second damper 64 is provided on the other branch pipe.

[0046] When the above-mentioned water purifier is in use, the controller controls the heating pipe and the refrigeration component 50 to turn on, and at the same time controls the first damper 63 to turn on, the second damper 64 to close, and the fan 62 to turn on. The heating pipe heats the water in the hot water storage tank 40, and the refrigeration component 50 cools the water in the cold water storage tank 30. Under the action of the fan 62, the air flow enters the heat conduction pipe 61 from the air inlet 611 and flows toward the air outlet 612. The air flow becomes a hot air flow when it flows through the hot end. The hot air flow flows through the hot water storage tank 40 and then flows out from the air outlet 612.

[0047] The first temperature sensor provided in the hot water storage tank 40 obtains the temperature of the hot water in the hot water storage tank 40. The data obtained by the first temperature sensor is transmitted to the controller. When the hot water temperature is within a first set range, the controller controls the heating pipe to turn off. The second temperature sensor provided in the cold water storage tank 30 obtains the temperature of the cold water in the cold water storage tank 30. When the cold water temperature is within a second set range, the controller controls the refrigeration assembly 50 to turn off. When the cold water temperature is higher than the upper limit of the second set range, the controller controls the refrigeration assembly 50 to turn on.

[0048] When the refrigeration assembly 50 is on, the first damper 63 is open, the second damper 64 is closed, and the fan 62 is on, the fan 62 directs airflow through the hot end and the hot water tank 40 to maintain the temperature of the hot water tank 40. If the temperature of the hot water in the hot water tank 40 exceeds the upper limit of the first set range, the controller controls the second damper 64 to open and the first damper 63 to close, and the fan 62 directs airflow through the hot end and out the exhaust port 613. If the temperature of the hot water in the hot water tank 40 falls below the first set value, which is less than the lower limit of the first set range, the controller controls the heater to turn on and heat the water in the hot water tank 40 until the hot water temperature is within the first set range. The controller then controls the heater to turn off. When the refrigeration assembly 50 is off, the fan 62 is turned off.

[0049] The specific temperature range can be set according to actual conditions. For example, when the hot water temperature is within the range of [70°C, 90°C], the heating pipe is turned off. When the cold water temperature is within the range of [-10°C, 0°C], the refrigeration component 50 is turned off. When the cold water temperature is higher than 0°C, the refrigeration component 50 is turned on. When the refrigeration component 50 is in the on state, the first damper 63 is opened and the second damper 64 is closed, and the fan 62 is turned on to guide the air flow through the hot end to keep the hot water storage tank 40 warm. If the hot water temperature in the hot water storage tank 40 is higher than 90°C, the second damper 64 is opened and the first damper 63 is closed, and the fan 62 is turned on to guide the air flow through the hot end and discharge it from the exhaust port 613. If the hot water temperature in the hot water storage tank 40 is lower than 65°C, the heating pipe is turned on to heat the water in the hot water storage tank 40 until the hot water temperature is within the range of [70°C, 90°C].

[0050] The above embodiments merely illustrate the basic principles and features of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications are possible without departing from the spirit and scope of the present invention. Such changes and modifications are within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
