Background technique

Chinese patent application documents 201410693732.3, 201510010484.2, 201711285250.4, and 201711285342.2 disclose that "a water purifier with an upper control module and a lower water collecting filter bin" has the following advantages: simple machine structure, stable assembly quality, high efficiency; easy disassembly and assembly , labor-saving; the filter cartridge is easy to extract and replace, and the water in the filter channel will not overflow to pollute the environment during the process of replacing the filter cartridge, and the filter cartridge on which the inner bladder is placed can be removed for separate disassembly and cleaning, and the U-shaped filter can be cleaned. In view of the fact that the U-shaped bile filter cavity constitutes the lower filter bile silo supporting the filter bile, and at the same time, the water-passing control component is arranged on the upper control module, so that the machine forms a movable double-layer structure, so that it can be used in a limited size. In the space, there is a large area of "upper operation surface", water control components and water pipeline placement space, and the lower filter tank can be easily opened, and at the same time, it can meet the requirements of display control, component maintenance, filter tank replacement, and filter tank cleaning. The respective functional requirements, as well as the manufacturing requirements of simple machine structure and low cost, and can make full use of the "concentrated water" discharged from the reverse osmosis membrane and nanofiltration membrane filter, which has a significant water saving function; the user can open the upper cover by himself. Replacing the filter element avoids the inconvenience and service expenses caused by professional appointments for door-to-door service, correspondingly reduces the cost of using the filter element, and also facilitates remote users. For the water purifier with the upper control module and the lower water collection type bile silo, when the upper control module is required to be provided with an upper water passage connected to the water control component and the filter in the lower water collection type bile silo When the bile water port is connected, it is necessary to set the lower end face of the upper control module downward and connect the upper docking water port of the upper water passage pipe, and at the same time, set the lower water collecting filter tank upward and connect the lower water tank including the filter bladder. Set the bottom docking port of the water pipe. When the upper control module is in contact with the lower water collecting filter tank. The upper and lower docking nozzles are also docked at the same time, and the fitting gap between the upper and lower docking nozzles is sealed with a nozzle seal. However, in order to facilitate the maintenance of the machine and the cleaning of the lower water collection type bile silo, the external pipelines of the machine, such as the inlet and outlet pipelines and the concentrated water drainage pipeline, are usually connected to the upper control module, and the corresponding upper and lower water ports are connected. A nozzle seal is also required at the mating part. Moreover, because the water passage of the machine needs to withstand the pressure of the tap water, and the booster pump is set in the water purifier to provide a higher water pressure for the reverse osmosis membrane filter, resulting in a larger fit of the nozzle seal. The nozzle seal creates resistance between the moving upper and lower butt nozzles. In the process of placing the upper control module on the lower water collecting filter tank, it is often affected by the water outlet seal and cannot be fully contacted and fitted in place. A downward external force must be applied to make the two parts fully contact and fit, otherwise it will be used for the upper control module. , The internal and external threaded structural parts connected by the lower two parts are idling due to the difficulty in contact, or the upper and lower tooth-revolving structural parts of the tooth-revolving mechanism are difficult to be inserted into each other in place (corresponding to the complete contact of the two parts) Then they cannot be screwed into each other. If the length of one threaded structural member of the internal and external threaded structural members is increased, the upper control module and the lower water collecting type bile silo are placed in the affected area of the corresponding nozzle seal when it contacts and cooperates with the other threaded structural member. In addition, due to the mutual pushing effect of the upper and lower end faces of the respective thread structures of the upper and lower parts, the large-sized upper control module (corresponding to the maximum size of the machine: 500×200×490) is in a "single pivot swing state". Moreover, there are more difficult situations in the process of removing the upper control module and replacing the filter element: it is difficult for one person to control the total water passing weight of 15-20 kg, which is affected by the tightness of the nozzle seal and is connected with multiple external pipelines. The upper and lower parts are separated, which makes it difficult for the machine user to operate in the process of contacting and matching the upper control module with the lower water collecting type bile filter bin, and separating the upper control module and the lower water collecting type bladder filter chamber, and It requires a lot of labor intensity, especially when the machine is equipped with multiple sets of upper and lower docking nozzles. For example, for a water purifier with a water circuit switcher, the water circuit switcher is set on the upper control module due to the need for control, so that the water inlet and outlet of multiple filter cartridges are used as the lower docking water outlet. Corresponding to the upper control module The sealing butt joint of the upper butt joint leads to the need to set up numerous nozzle seals. The above-mentioned new problems and deficiencies caused by the water purifier with the upper control module and the lower water collecting type bile silo make it difficult for the new water purifier to be more widely popularized.

Detailed ways

Usually, the filter channels connecting the filter bladders and the water-passing control components are respectively connected with the inlet and outlet pipelines of the machine base to form the filter channels. Select the relevant water-passing control components to control the relevant water-passing pipelines involved in the filter channel of the machine base. The water passage control component is at least a water circuit switch or a water passage control valve or a water pressure control switch or a flow sensor or a water pump or a membrane drainage concentrated water flow control device or an ultraviolet sterilization device or a combined docking cavity or a TDS probe or a water level monitoring device 10 one of the components.

The above-mentioned water-passing control components are all conventional prior art, which does not mean that all of the above-mentioned water-passing control components must be used in this case. As for the water purifiers that need to be equipped with reverse osmosis membrane filters or nanofiltration membrane filters, it is necessary to select and combine according to the specific needs of various models and connect the corresponding water pipelines, unless otherwise specified. All belong to common knowledge in the field. This case will no longer describe the functions, principles and connected water-passing pipelines of the above-mentioned common water-passing control components of water purifiers.

In each embodiment of this case, a water purifier integrated with the upper-mounted control module and the lower-mounted water-collecting bile silo is inserted and matched up and down, and connected by a joint device to form an integrated water purifier. It includes the following three structural modes, and the corresponding filter channel connection modes are as follows:

The first filter channel connection mode:

The upper control module of the water purifier is placed with a water-passing control component, and a water-passing pipeline connected to the water-passing control component and a downward upper docking water port are arranged; When the upper control module is in contact with the upper and lower parts of the lower water collecting filter tank, the upper and lower docking nozzles of the filter tank are sealed and connected to each other. which is:

The upper part of the filter bladder is provided with a filter bladder with a "two-up water outlet" structure, and is connected and fixed with the lower water-collecting bladder filter bin through the fastening device provided on the filter bladder casing. The two upward and lower butt joints of the filter bladder are sealed and connected with the downward upper butt joints of the upper control module and the water-passing pipeline to form a filter channel.

The second filter channel connection mode:

The upper control module of the water purifier is provided with a downward upper docking water port and a water passage; the base of the lower water collecting type bile tank is provided with an upward and lower docking water port and a water passage; the filters are respectively Set up the upper and lower docking water openings upward; after the filter bladder is connected to the base of the lower water collecting type filter tank through the fastening device, the downward upper butting water opening of the filter bladder is connected with the lower water collecting type filter tank. The upward and downward plug-in water port of the tank base and the water passage pipeline are sealed and connected to each other; when the upper control module is in contact with the upper and lower parts of the lower water collecting filter tank, the upward and lower docking water port of the filter tank is connected to the upper control module. The upper plug-in water ports facing downward of the module are sealed and connected to each other; the water-passing control component is either arranged in the water-passing pipeline of the upper-mounted control module, or is arranged in the water-passing pipeline of the bottom-mounted water-collecting-type bile silo base, or They are respectively arranged in the respective water-passing pipelines of the upper control module and the lower water collecting type bile silo base.

In this embodiment, the above two structural modes of the filter water outlet (“two upward nozzles” and “different-direction nozzles”) are regarded as “each filter tank passes through the upper and lower docking nozzles set up on the upper part and the downward direction of the upper control module. The structure mode of the water filter outlet covered by the structure mode of the upper docking water port and the water-passing pipeline sealing connection connecting the water-passing control components".

The third filter channel connection mode:

The filter bladder connected in the filtering channel includes a filter bladder with two water inlets in the same direction, and is connected and fixed with the lower water collecting type filter bladder through a fastening device arranged near the two same direction water outlets to form an integral body. The two same-direction water ports of the filter bladder belong to two downward upper butt-joint water ports, which are sealed and connected with the upper and lower butt-joint water ports of the bottom of the lower water collecting type bile silo base and pass through the water passage of the bottom of the lower water collecting type bile silo base. Connections form filter channels.

For the three-water outlet filter, such as reverse osmosis membrane filter or nanofiltration membrane filter, it can be regarded as an addition to the "two-up nozzle" or "different direction nozzle" in the first and second filter channel connection modes. A nozzle can also be regarded as adding a nozzle on the basis of the two same-direction nozzles in the third filter channel connection mode.

In the various embodiments of this case, the water-passing control components can be arranged on the upper control module, or the lower water-collecting bile silo, or the upper control module and The bottom is placed on the water-collecting filter tank.

On this basis, a condensate drain tank (corresponding to the U-shaped silo structure water storage area in this case) and the return water of the return water control device are set in the concentrated water drainage pipeline of the reverse osmosis membrane filter or nanofiltration membrane filter. system, the water inlet pipe of the return water system, namely the return water inlet pipe, is connected to the outlet pipe of the concentrated water flow control device, and the water outlet pipe, namely the return water outlet pipe, is connected to the inlet pipe of the booster pump through the return water control device In addition, a water inlet electric control valve is installed in the water inlet pipeline before the connection of the return water outlet pipeline. The water inlet pipeline is the pre-filtration channel, and the connection of the return water outlet pipeline can be each position of the pre-filter channel formed by the pre-filters located in front of the reverse osmosis membrane filter or the nanofiltration membrane filter, or Each position of the pre-filter channel is formed by the composite pre-filter bladder composed of each pre-filter bladder, wherein preferably, the end of the pre-filter channel is directly connected to the water inlet pipeline of the booster pump. In this case, unless otherwise specified, the outlet pipe of the pre-filter is equivalent to the end of the pre-filter channel.

For a single outlet water purifier, the return water control device and the inlet water electronic control valve can choose one to conduct water or the booster pump to supply water and then produce pure water (pure faucet water).

For the double outlet water purifier, choose one of the return water control device and the water inlet electric control valve to conduct water or the booster pump to supply water to produce pure water (pure faucet water), or choose one to conduct the water purification faucet separately provided by the machine. The purified water filtered by the pre-filter bile is directly released (the concentrated water is also the purified water filtered by the pre-filter bile). At this time, the reverse osmosis membrane filter bile or nanofiltration membrane filter bile can not contain water.

In this case, the return water control device that controls the water discharge or stops the water discharge from the water storage area (concentrated water tank) of the U-shaped silo structure can be either an electric control valve or a concentrated discharge pump. On this basis, in order to meet the requirements of the booster pump for the water outlet flow of the U-shaped silo structure water storage area (concentrated water tank), the return water control device can also be an electric control valve that is connected to and controls a water outlet pipeline. Or the combination device of the drain pump in parallel, or to increase the effluent flow of the water storage area of the U-shaped silo structure (the drain tank), or to use the electronically controlled valve for the booster pump, and the drain pump for the high-level water outlet (such as the purified water outlet). ).

In addition, the return water control device can also be a combination device in which the electric control valve and the concentration drainage pump are connected in parallel to each other and control a water outlet pipeline, thereby increasing the outlet water flow of the concentrated drainage tank (U-shaped silo structure water storage area) to meet the requirements of Inlet water demand of the booster pump.

As far as the water flow mode is concerned, no matter which of the above-mentioned modes is adopted by the return water control device, it only involves how the water inlet and outlet pipes are connected with the relevant water passage pipes. The return water control device in the return water outlet pipeline behind the concentrated water tank in the water area can adopt one of the above five modes, and the relevant pipelines connected in series with the return water control device can be connected in series. The electric control valve or the return water outlet pipeline of one concentrated drainage pump can also be the return water outlet pipeline of two electric control valves or two concentrated drainage pumps or the electric control valve and the concentrated drainage pump connected in parallel.

In this case, as the concentrated water tank, the volume space of the water storage area of the U-shaped silo structure is the space between the U-shaped silo structure and the outer sides of the multiple filters including the pre-filter and reverse osmosis membrane filters.
