Description

[Technical field]

[0002] The utility model relates to the field of water purification of drinking water equipment, in particular to the technical field of large-flow instant purifying and heating drinking water equipment. [Background technology]

[0004] As the degree of industrialization increases, people's living standards are getting higher and higher, and the requirements for drinking water quality are also constantly increasing. Therefore, more and more families are equipped with drinking water filtration equipment, purification equipment or water softeners, etc., all to further improve the quality of drinking water. Therefore, drinking water purification equipment has gradually become a necessity of life. With the improvement of the quality of life, people's requirements for drinking water are gradually increasing, requiring healthy drinking water, temperature adjustment, no waiting, and fast water collection.

[0005] After purification, water needs to be heated before it can be drunk so that the temperature meets the needs of making tea, preparing beverages, and drinking warm water. In order to better meet the needs of users, improve the functional completeness of the equipment and avoid the need to repeatedly configure multiple sets of different treatment equipment, consider designing an integrated direct drinking equipment from water purification to heating. This way, you can get drinkable water of the right temperature directly with one set of equipment in one step, while ensuring the health of the water quality and the needs of different water temperatures.

[0006] There are also some so-called all-in-one water purifiers and heat machines on the market, which combine the front-end water purification equipment and instant heating equipment. The water passing through the purification equipment is heated by the instant heating equipment to obtain drinking water of suitable temperature. However, the water purification flow rate of existing conventional products is relatively large, while the instant heating flow rate is relatively small. Instant heating products are generally limited by the national standard for household appliances, which is that the maximum power does not exceed 2200W, and the maximum boiling water flow rate is only 400ml / min. In winter, it will be reduced to an even lower 300ml / min. The flow limitation has always been a point of dissatisfaction for users, and it cannot meet the users' needs for quick water collection. In addition, in general, there is a pure water tank inside this direct drinking machine, and the pure water tank will have secondary pollution problems when it comes into contact with the air.

[0007] Therefore, a drinking water method that combines purified water with drinking water is needed, while ensuring the health of the water quality and the water temperature requirements. For example, making tea, mixing milk, and warm water, etc., require different temperatures. [Summary of the invention]

A zero-pressure valve is used to directly connect to the water source to achieve no water tank and no secondary pollution. The hot water circulation of the entire pipeline is used to achieve circulating sterilization.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0048] Embodiment 1:

[0049] Please refer to the attached Figure 1 , which shows an embodiment 1 of a large flow direct drinking device involved in the utility model, which includes a water inlet 10, a water pump 20, a filter element 30, an instant heating component 40, a thermometer and a water outlet 50, and also includes a water inlet solenoid valve 11. The water source entering the system from the water inlet 10 is controlled by the water inlet solenoid valve 11, which is responsible for the opening and closing of the water inlet of the entire system;

[0050] The filter element 30: The filter element is a four-in-one filter element or a five-in-one filter element, and includes an RO filter element. Water entering from the water inlet 10 will be connected to the filter element 30, and the water purification process is carried out through the filter element 30;

[0051] Booster pump 50: It is arranged between the water inlet solenoid valve 11 and the filter element 30 to provide pressurized water to the filter element 30. Considering the principle of the RO filter element, it is necessary to provide water with a certain pressure to enter it so that the reverse osmosis process can be more efficient and have a larger filtration flow. The booster pump 50 is configured to increase the water inlet pressure of the water entering the filter element 30 to ensure that the pressure meets the subsequent processing requirements.

[0052] Phase change energy storage module 60: the water outlet of the filter element 30 is connected to the phase change energy storage module 60, in which a heat exchanger and a phase change material are provided, wherein the water passing through the phase change energy storage module flows through the heat exchanger pipe buried in the phase change material;

[0053] Water pump 20: A water pump 20 is provided between the water outlet of the filter element 30 and the water inlet of the phase change energy storage module 60 to extract water from the source and input it into the system;

[0054] Zero-pressure valve 21: A zero-pressure valve is provided between the water outlet from the filter element 30 and the water pump 20; the zero-pressure valve reduces the pressure of the pressurized water source to zero pressure, which is a known technology.

[0055] Solenoid valve 61: A solenoid valve 61 for switching the water path is provided between the water pump 20 and the water inlet end of the phase change energy storage module 60. The solenoid valve 61 switches between two water paths, one of which enters the phase change energy storage module and the other bypasses the phase change energy storage module. The function of the solenoid valve 61 is to conduct different water paths according to different needs, allowing water to flow through the phase change energy storage module, or short-circuit the phase change energy storage module.

[0056] The solenoid valve 61 is a one-inlet and two-outlet switching solenoid valve or a combination of two solenoid valves.

[0057] Instant heating component 40: The instant heating component includes a heating body, a device that converts electrical energy into thermal energy. The two water paths through the solenoid valve are finally connected to the instant heating component 40, that is, the water path through the phase change energy storage module 60 and the water path bypassing the phase change energy storage module 60 are connected to the instant heating component;

[0058] When the heating body in the heating component 40 is started, the water passing therethrough can be heated, and a certain flow of boiled water and a larger flow of warm water can be provided.

[0059] The water path after passing through the instant heating component 40 is divided into one, one connected to the water outlet 70, and the other is divided into a circulating water path, which is connected to the node between the zero pressure valve and the water pump;

[0060] Circulation solenoid valve 41: A circulation solenoid valve is provided at the starting end of the circulation water circuit, which is responsible for opening and closing the circulation water circuit. The circulation water circuit circulates the water heated by the instant heating component 40 to the phase change energy storage module for energy storage.

[0061] A faucet or other water outlet device is provided at the water outlet 70, and water is discharged through a switch control system.

[0062] Example 2: Please refer to the attached Figure 2 The structure of Example 2 is shown.

[0063] The difference between this embodiment and embodiment 1 is that a normal temperature pure water outlet pipeline and a zero cold water return pipeline are configured in the system, wherein the normal temperature pure water outlet pipeline is a passage directly connected from the water outlet of the filter element to the water outlet, and only one normal temperature pure water solenoid valve 12 is provided on the normal temperature pure water outlet pipeline.

[0064] In this embodiment, a buffer component 80 is provided at the water branch node after the instant heating component discharges water. The buffer component 80 is externally connected to a zero cold water return pipeline to the node between the water inlet solenoid valve 11 and the booster pump 50, and a zero cold water return solenoid valve 81 is provided on the zero cold water return pipeline.

[0065] The buffer component 80 plays the role of: the system is preheated by reflux, and due to the influence of thermal expansion and contraction, a container needs to be added. Before preheating, part of the water in the container is pumped out to buffer the volume change caused by thermal expansion and contraction.

[0066] The zero cold water return pipeline is set to reduce the impact of cold water in the water intake system. After each heating is completed, the remaining water in the buffer component 80 and the water outlet pipeline is pumped away by the booster pump 50 to reduce the impact of cold water in the next water intake system.

[0067] The filter element is a four-in-one filter element 30, which includes a PP cotton filter element, a front activated carbon filter element, a reverse osmosis RO filter element and a rear activated carbon filter element. A pure water reflux solenoid valve 31 is provided at the water outlet of the four-in-one filter element to return the filter outlet water to the front end of the booster pump. As is known to all, all reverse osmosis filter elements have the first cup of water problem (after the whole machine is shut down, the salt at the front end of the RO membrane will slowly penetrate into the pure water end, resulting in the phenomenon that the first cup of desalination rate used next time does not meet the requirements). The pure water reflux solenoid valve returns the pure water at the rear end of the RO membrane to the front end of the reverse osmosis membrane to improve the desalination rate of the first cup of water. This is the role of the pure water reflux solenoid valve 31.

[0068] The filter element 33 further includes a wastewater outlet 33 and a flushing solenoid valve 32 disposed at the wastewater outlet 33 .

[0069] A flow meter 90 is provided before the zero-pressure valve.

[0070] The thermometer includes a module thermometer and a water inlet thermometer. The module thermometer is arranged in the phase change energy storage module, and the water inlet thermometer is arranged at the water inlet end of the heating body. The system needs to monitor the temperature in the phase change energy storage module and the water temperature before heating in real time so that the system can adjust and control the normal operation of heating and water supply.
