Abstract
Description
Technical Field
[0001] This application relates to the field of water purification technology, and in particular to an integrated water purifier and heat pump and its instant hot water circuit system. Background Technology
[0002] In my country, boiled water symbolizes safe and hygienic water quality, and drinking fully boiled and naturally cooled water is widely considered a healthy way to drink water. However, the traditional process of boiling water and letting it cool naturally takes a long time, which is inconvenient, especially when users urgently need water. With the increasing demand for convenient living, various instant hot water purifiers have emerged on the market, providing hot water at different temperature levels through rapid heating to meet diverse drinking needs.
[0003] While existing instant hot water purifiers offer multiple temperature settings, the water in the warm / hot water settings is directly heated to the target temperature by a heater, without undergoing a complete boiling and natural cooling process, which doesn't align with users' traditional understanding of boiled water. Some products use instant heating technology to instantly output cooled or boiled water at the corresponding temperature setting, but due to the power limitations of these devices, they cannot provide a large flow of hot water in real time, failing to meet the needs of large drinking volumes and resulting in a poor user experience. Utility Model Content

[0024] In one embodiment, the system further includes:
[0025] The second water pump has its inlet connected to the outlet of the insulation tank, and its outlet connected to the inlet of the instantaneous heating element.
[0026] Secondly, this application provides an integrated water purifier and heat pump, including any of the instant hot water circuit systems provided in the first aspect; the first water outlet of the integrated water purifier and heat pump is connected to the water outlet of the filter component through a fifth water outlet; the second water outlet of the integrated water purifier and heat pump is connected to the drinking water outlet of the integrated temperature control valve.

[0037] Firstly, please refer to Figure 1 , Figure 1 This diagram illustrates the structure of an instant hot water system according to an embodiment of the present invention. The instant hot water system provided in this embodiment includes a heat exchanger 30, a hot water channel 301, and a normal temperature water channel 302. The outlet of the normal temperature water channel 302 is connected to the inlet of the instant heating element 40 via a first inlet channel 401. A heat preservation tank 60 has its inlet connected to the outlet of the instant heating element 40 via a first outlet channel 403, and its outlet connected to the inlet of the instant heating element 40 via a second inlet channel 402. An integrated temperature control valve 50 has its heating inlet connected to the outlet of the instant heating element 40 via a second outlet channel 404. The hot water channel includes the heat exchanger 30, the instant heating element 40, the heat preservation tank 60, and the integrated temperature control valve 50.
[0038] Optionally, the heat exchanger 30 is a two-inlet, two-outlet component, comprising a room temperature water channel 302 and a hot water channel 301. The room temperature water channel 302 and the hot water channel 301 are arranged adjacent to each other or in a nested structure to achieve heat exchange between them. The inlet of the room temperature water channel 302 is connected to the outlet of the first outlet pump 10 to introduce room temperature water. The outlet of the room temperature water channel 302 is connected to the inlet of the instantaneous heating element 40 through the first inlet water passage 401. Optionally, a one-way valve 103 is provided between the outlet of the room temperature water channel 302 and the inlet of the instantaneous heating element 40 (i.e., on the first inlet water passage 401). The one-way valve 103 can prevent backflow of water and ensure that the water always flows from the room temperature water channel 302 to the instantaneous heating element in the designed direction. After heat exchange with the hot water channel 301, the temperature of the room temperature water inside the room temperature water channel 302 rises. The heated room temperature water flows through the outlet of the room temperature water channel 302 to the first inlet channel 401, and through the first inlet channel 401, the heated room temperature water is transported to the instantaneous heating element 40. The instantaneous heating element 40 further preheats the heated room temperature water to obtain warm water. This warm water flows through the outlet of the instantaneous heating element 40 into the first outlet channel 403, and is then transported to the insulation tank 60 for storage, which can improve the efficiency of subsequent hot water preparation. A water supply valve 104 is provided between the outlet of the instantaneous heating element 40 and the inlet of the insulation tank 60 (i.e., on the first outlet channel 403). This water supply valve 104 can be opened when warm water needs to be stored, allowing the preheated warm water from the instantaneous heating element 40 to be introduced into the insulation tank as needed; the valve is closed when not needed.
[0039] When a user needs hot water, the warm water stored in the insulated tank 60 flows into the instant heating element 40 through the tank's outlet and the second inlet 402. This allows the instant heating element 40 to reheat the stored warm water in the tank 60, producing hot water. This hot water then flows through the outlet of the instant heating element 40 into the second outlet 404, and is subsequently delivered to the heating inlet of the integrated temperature control valve. The integrated temperature control valve then outputs the hot water to the outlet of the integrated water purifier and heat exchanger for the user. This preheating process by the instant heating element 40 effectively improves the heating efficiency when hot water is subsequently dispensed. The preheated warm water is then stored in the insulated tank 60. When the user needs hot water, it is directly taken from the insulated tank 60 for reheating, providing a higher water flow rate and improving the user experience.
[0040] In the previous exemplary embodiment, the system further includes: a second water pump 20, the inlet of which is connected to the outlet of the heat preservation tank 60, and the outlet of which is connected to the inlet of the instantaneous heating element 40.
[0041] For example, a second water pump 20 is provided between the outlet of the heat preservation tank 60 and the inlet of the instant heating element 40 (i.e., on the second water inlet 402). When the user issues a hot water command, the second water pump 20 draws warm water from the heat preservation tank 60 and pumps the warm water through the second water inlet 402 to the instant heating element, so that the instant heating element 40 performs secondary heating treatment on the warm water to obtain hot water.
[0042] Compared to traditional methods of directly heating room temperature water, this embodiment utilizes a heat exchange structure between the room temperature water channel 302 and the hot water channel 301 to preheat the room temperature water with high-temperature hot water. This reduces the heating burden on the subsequent preheating process of the instant heating element 40, significantly improving overall thermal efficiency and reducing energy consumption. The preheated warm water is stored in the insulation tank 60, ensuring a certain amount of hot water is readily available. When a user needs hot water, only a second rapid heating of the warm water is required, effectively avoiding the waiting time caused by cold starts and increasing the amount of hot water output per unit time, thus improving the user experience. Simultaneously, by using the insulation tank 60 to buffer the warm water resources, combined with the rapid heating capability of the instant heating element 40, hot water at the target temperature can be provided immediately when the user draws water, avoiding the problem of excessively long waiting times caused by low initial water temperature in traditional instant heating devices.
[0043] In an exemplary embodiment, the system further includes: a first water pump 10, the inlet of which is connected to the clean outlet of the integrated temperature control valve 50 via a third water inlet 106; and the outlet of the first water pump 10 is connected to the inlet of a normal temperature water channel.
[0044] In the above, the inlet of the hot water channel 301 is connected to the outlet of the instantaneous heating element 40 through the third outlet channel 405; the outlet of the hot water channel 301 is connected to the heat exchange inlet of the integrated temperature control valve 50; wherein, the clean circulating water channel includes the first outlet pump 10, the normal temperature water channel, the instantaneous heating element 40, the hot water channel 301 and the integrated temperature control valve 50.
[0045] Optionally, the inlet of the first water pump 10 is connected to the outlet of the ambient temperature water tank 70 via the fourth inlet channel 107. The inlet of the hot water channel 301 is connected to the outlet of the instantaneous heating element 40 via the third outlet channel 405 to receive the hot water output by the instantaneous heating element 40; the outlet of the hot water channel 301 is connected to the heat exchange inlet of the integrated temperature control valve 50, so that the hot water flows into the integrated temperature control valve 50 and is connected to the inlet of the first water pump via the third inlet channel 106 through the clean outlet of the integrated temperature control valve 50.
[0046] For example, the cleaning circulation water path is as follows: first outlet pump 10 → ambient temperature water channel 302 of heat exchanger 30 → instantaneous heating element 40 (heating function activated) → solenoid valve 105 → hot water channel 301 of heat exchanger 30 → integrated temperature control valve 50 → first outlet pump 10, thus forming a closed-loop circulation process. In this cleaning mode, all other water channels in the system except this circulation water channel are closed to avoid interfering with the cleaning process. Specifically, the inlet of the first outlet pump 10 is connected to the outlet of the ambient temperature water tank 70 through the fourth inlet channel 107, for drawing ambient temperature water from the ambient temperature water tank 70 and pumping the ambient temperature water to the ambient temperature water channel 302; the ambient temperature water undergoes heat exchange with the hot water channel 301 in the ambient temperature water channel 302 and then enters the instantaneous heating element 40, or the ambient temperature water directly enters the instantaneous heating element 40 via the ambient temperature water channel 302; the instantaneous heating element 40 will be heated by the ambient temperature water channel 302. The input water is heated to a set sterilization temperature to form sterilized hot water. This sterilized hot water is output from the outlet of the instantaneous heating element 40, guided by the solenoid valve 105 to the third water outlet 405, and then flows to the hot water channel 301. The sterilized hot water flows into the integrated temperature control valve 50 through the outlet of the hot water channel 301, and then flows into the inlet of the first water pump 10 through the cleaning outlet of the integrated temperature control valve 50 via the third water inlet 106, completing one cleaning cycle. The above cycle can be continuously operated for multiple cycles to achieve high-temperature sterilization of the heat exchanger 30 and related water channels, and efficient cleaning of the internal pipes.
[0047] In this embodiment, high-temperature hot water with sterilization ability is obtained through the instantaneous heating element 40, which can perform high-temperature sterilization treatment on the hot water pipes in the heat exchanger 30, the normal temperature water channel 302 and the inside of the instantaneous heating element 40, effectively inhibiting bacterial growth and ensuring the safety of drinking water.
[0048] In an exemplary embodiment, the inlet of the first water pump 10 is also connected to the outlet of the ambient temperature water tank 70 through the fourth water inlet 107; wherein, the cooled boiled water circuit includes the ambient temperature water tank 70, the ambient temperature water channel 302, the instant heating element 40, the hot water channel 301, and the integrated temperature regulating valve 50.
[0049] The inlet of the first water pump 10 is connected to the outlet of the ambient temperature water tank 70 via the fourth water inlet 107. The outlet of the first water pump 10 is also connected to the inlet of the ambient temperature water channel 302, for supplying ambient temperature water to the ambient temperature water channel 302. The inlet of the hot water channel 301 is connected to the outlet of the instantaneous heating element 40 via the third water outlet 405, for receiving the hot water output from the instantaneous heating element 40. The ambient temperature water channel 302 and the hot water channel 301 are arranged adjacent to each other or in a nested structure to achieve heat exchange between them. Specifically, after heat exchange with the ambient temperature water channel 302, the temperature of the hot water in the hot water channel 301 decreases, forming cooled boiled water. The cooled boiled water enters the heat exchange inlet of the integrated temperature control valve through the outlet of the hot water channel 301, allowing it to flow into the integrated temperature control valve 50 and out through the drinking water outlet for the user. In this embodiment, this heat exchange structure not only enables efficient preparation of cooled boiled water but also recovers heat energy, reduces energy consumption, and improves the overall thermal efficiency of the system.
[0050] For example, when a user issues a command to request cooled boiled water (e.g., at 45℃), the second water pump 20 starts, drawing stored warm water from the insulated tank 60. This warm water is delivered to the instant heating element 40 via the outlet of the second water pump 20, where it undergoes secondary heating to obtain hot water. This hot water flows through the solenoid valve 105 and into the hot water channel 301 via the third water outlet 405. In the hot water channel 301, the hot water exchanges heat with the adjacent ambient temperature channel 302, lowering the water temperature to obtain cooled boiled water. This cooled boiled water is then delivered through the outlet of the hot water channel 301 to the heat exchange inlet of the integrated temperature control valve 50, and finally delivered to the user's port through the drinking water outlet of the integrated temperature control valve 50 for direct drinking.
[0051] In the above description, the integrated temperature control valve 50 is an adjustable flow valve assembly with two inlets and two outlets. The integrated temperature control valve 50 includes a heat exchange inlet, a heating inlet, a drinking water outlet, and a cleaning outlet. The heat exchange inlet of the integrated temperature control valve 50 is connected to the outlet of the hot water channel 301, allowing access to cooled boiled water after heat exchange. The heating inlet of the integrated temperature control valve 50 is connected to the outlet of the instant heating element 40 via a second outlet channel 404, allowing access to hot water output from the instant heating element 40. Optionally, the heat exchange inlet and heating inlet of the integrated temperature control valve 50 can be selectively connected to its drinking water outlet, forming a single channel or a mixed channel. The drinking water outlet of the integrated temperature control valve 50 is connected to the outlet of the integrated water purifier and heater, used to output drinking water (cooled boiled water, hot water, or temperature-regulated cooled boiled water) for direct consumption by the user.
[0052] In an optional embodiment, the heating inlet and heat exchange inlet of the integrated temperature control valve 50 are both connected to the drinking water outlet of the integrated temperature control valve 50.
[0053] For example, the heating inlet of the integrated temperature control valve 50 is connected to the drinking water outlet of the integrated temperature control valve 50, or the heat exchange inlet of the integrated temperature control valve 50 is connected to the drinking water outlet of the integrated temperature control valve 50. For instance, when a user issues a command to obtain hot water, only the heating inlet of the integrated temperature control valve 50 is connected to the drinking water outlet; when a user issues a command to obtain cooled boiled water, only the heat exchange inlet of the integrated temperature control valve 50 is connected to the drinking water outlet.
[0054] In another alternative embodiment, the heating inlet and the heat exchange inlet of the integrated temperature control valve 50 are simultaneously connected to the drinking water outlet of the integrated temperature control valve 50.
[0055] Optionally, when a user issues a command to obtain cooled boiled water, the heating inlet and heat exchange inlet of the integrated temperature control valve 50 can be simultaneously connected to the drinking water outlet of the integrated temperature control valve 50, thereby enabling the mixed regulation of hot water and cooled boiled water output from the hot water channel to adapt to multiple temperature requirements.
[0056] The system also includes a temperature detector located at the drinking water outlet of the integrated temperature control valve 50. The temperature detector adjusts the flow rate ratio between the heating inlet and the heat exchange inlet of the integrated temperature control valve 50 to control the temperature of the cooled boiled water circuit.
[0057] The drinking water outlet of the integrated temperature control valve 50 is equipped with a temperature detector. When both the heating inlet and the heat exchange inlet of the integrated temperature control valve 50 are connected to the drinking water outlet, the temperature detector monitors the real-time water temperature at the outlet. Specifically, when a user issues a command to obtain cooled boiled water and sets a target temperature, the temperature detector collects the current water temperature data and dynamically adjusts the opening degree and flow ratio of the heating inlet and heat exchange inlet of the integrated temperature control valve 50 based on the detector's readings. This achieves precise control of the mixed water temperature. This adjustment method can meet the water temperature requirements of different settings, ensuring a stable and accurate output of cooled boiled water, improving the user's drinking experience and the system's intelligence.
[0058] In this embodiment, the integrated temperature control valve 50 is an adjustable flow valve assembly with two inlets and two outlets. Based on the temperature signal fed back by the temperature detector, it dynamically adjusts the flow ratio of hot water and cooled boiled water, forming a closed-loop temperature control mechanism and improving user comfort. By installing a temperature detector at the drinking water outlet of the integrated temperature control valve 50, precise control of drinking water temperature can be achieved; it can meet the water output requirements of different set temperatures, ensuring that the output cooled boiled water temperature is stable and accurate, improving the user's drinking experience and the system's intelligence.
[0059] In an exemplary embodiment, the system further includes: a filter assembly 80, the outlet of which is connected to the inlet of a room temperature water tank 70 via a fourth water outlet path 801; the outlet of the filter assembly 80 is also connected to a room temperature solenoid valve 102 via a fifth water outlet path 802; wherein, the room temperature water path includes the filter assembly 80 and the room temperature solenoid valve 102.
[0060] The specific combination of the filter components 80 can be flexibly configured according to the application scenario. For example, the filter components 80 may include some or all of the following filter elements: RO reverse osmosis filter element, nanofiltration fine filter element, pre-filter element, and post-filter element; optionally, the filter components 80 may also include other components with filtration functions.
[0061] Optionally, the outlet of the filter assembly 80 is connected to the inlet of the ambient temperature water tank 70 via a fourth water outlet 801, providing filtered ambient temperature water to the tank. A water replenishment solenoid valve 101 is provided between the outlet of the filter assembly 80 and the inlet of the ambient temperature water tank 70. This solenoid valve 101 acts as an on / off control element, allowing filtered purified water (ambient temperature water) to flow into the ambient temperature water tank. The outlet of the filter assembly 80 can also be connected to the ambient temperature solenoid valve 102 via a fifth water outlet 802, and then to the first outlet of the water purifier via the ambient temperature solenoid valve 102, directly outputting filtered purified water (ambient temperature water) to the user's port to meet the user's demand for ambient temperature purified water. Specifically, when the user issues a command to dispense ambient temperature water, the filter assembly 80 obtains filtered ambient temperature water, which is then delivered to the first outlet of the water purifier via the ambient temperature solenoid valve 102 for direct use by the user. Through the above settings, this instant hot water circuit system achieves integrated supply of room temperature water, hot water, and cooled boiled water, improving the functionality and ease of use of the equipment.
[0062] Secondly, this application provides an integrated water purifier and heat pump, including any of the instant hot water circuit systems provided in the first aspect; the first water outlet of the integrated water purifier and heat pump is connected to the water outlet of the filter component 80 through the fifth water outlet 802; the second water outlet of the integrated water purifier and heat pump is connected to the drinking water outlet of the integrated temperature control valve 50.
[0063] Optionally, the first water outlet of the integrated water purifier and heater is connected to the outlet of the filter assembly 80 via the fifth water outlet 802, allowing filtered purified water (room temperature water) to be directly output to the user's port to meet the user's need for room temperature purified water. The drinking water outlet of the integrated temperature control valve 50 is connected to the second outlet of the integrated water purifier and heater, used to output cooled boiled water or hot water, which has been mixed and regulated by the integrated temperature control valve 50, to the user's port. Through the above connection method, unified outlet control of drinking water at different temperatures (such as hot water, cooled boiled water, and cooled boiled water at a preset temperature) can be achieved, improving the convenience of water access for users, and also facilitating the integrated design and space optimization of the water circuit system.
[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
