Description

Technical Field

[0001] This utility model relates to the field of water mixing control technology, specifically to a water mixing device that is easy to install and use. Background Technology

[0002] Underfloor heating is widely used in various residential and office buildings. The pipes are laid in a concealed manner below the ground, and the ground is usually covered with wooden boards or tiles. The mixing device is an important core component of underfloor heating. The manifold and distributor in the mixing device circulate the mixed hot water into the pipe system, thereby achieving the purpose of heating.

[0003] For the underfloor heating system to circulate heat, after the hot water returns to the piping system, part of it continues to circulate and the other part returns to the external piping system. This process requires the installation of a diversion device in the system. The existing structure selects to install this return diversion device separately at the return point, which not only increases the cost of use but also increases the installation trouble. Furthermore, with use, a lot of impurities will accumulate in the pipes. The current method is to add a filter and a drain valve at the inlet end, but these all need to be installed separately, which is not only troublesome to install but also has a high cost of use. Therefore, it is necessary to improve the existing structure to address the technical defects mentioned above. Summary of the Invention

[0020] The present invention will be further described in conjunction with the accompanying drawings.

[0021] Please see Figures 1 to 4 This utility model provides a water mixing device that is easy to install and use, including a water distributor 1, a water collector 2, and a temperature-controlled mixing valve 3; the water collector 2 includes a water collecting valve body 4, a water inlet connector 5, a water inlet valve core assembly 6, a water outlet connector 7, a water collecting connector 8, a diversion valve core assembly 9, and a return water connector 10; the water distributor 1 includes a water diversion valve body 11, a mixing water inlet connector 12, and a mixing water outlet connector 13; the temperature-controlled mixing valve 3 is connected to the water outlet connector 7 and the mixing water inlet connector 12 respectively.

[0022] The diversion valve core assembly 9 includes an inner diversion valve body 14 and a one-way valve 15. The return water connector 10 positions and installs the inner diversion valve body 14 in the water collection valve body 4, and the return water connector 10 communicates with the interior of the inner diversion valve body 14. One end of the inner diversion valve body 14 is sealed to the water collection valve body 4, so that the interior of the water collection valve body 4 forms an inlet chamber 16 and a return water chamber 17. One end of the inner diversion valve body 14 communicates with the return water chamber 17, and a one-way valve 15 is installed at the other end of the inner diversion valve body 14. The one-way valve 15 controls the water flow inside the inner diversion valve body 14 to return to the inlet chamber 16.

[0023] The inner diversion valve body 14 is provided with a positioning mounting hole 19. The return water connector 10 is screwed onto the water collecting valve body 4, and its end is positioned and fitted through the positioning mounting hole 19. A sealing ring is provided between the return water connector 10 and the positioning mounting hole 19. The water collecting valve body 4 is provided with a valve body positioning part 20. One end of the inner diversion valve body 14 is positioned and fitted onto the valve body positioning part 20. A sealing ring is provided between the end of the inner diversion valve body 14 and the valve body positioning part 20.

[0024] After the hot water supplied to the pipeline system enters the return water chamber 17 through the water collector 8, part of it flows back to the external pipeline system through the return water connector 10, and part of it flows back to the inlet water chamber 16 through the one-way valve 15 at the end of the internal diversion valve body 14, where it is finally mixed and reused. Since the one-way valve 15 is controlled by one-way water flow, the return water in the return water chamber 17 can only flow to the inlet water chamber 16. This structure is simple in design and ingenious in installation, requires no separate installation, has low cost, and is easy to promote and use.

[0025] Furthermore, the water distributor 1 is equipped with a filter device 18, which filters the mixed water and then flows out through the mixed water outlet 13; the water distributor valve body 11 of the water distributor 1 is equipped with a filter mounting part 21, and a filter mounting hole 22 is provided at the filter mounting part 21. A plug cap 23 is installed in the filter mounting hole 22, and a sealing ring is also provided between the plug cap 23 and the filter mounting hole 22; the filter device 18 includes a filter screen 24 and a positioning cylinder 25. The mixed water outlet 13 presses and fixes the filter screen 24 in the filter mounting part 21 through the positioning cylinder 25. The filter screen 24 is located between the filter mounting hole 22 and the mixed water outlet 13.

[0026] The filter screen in the filtration device can filter the mixed water in the distributor before it flows to the pipeline system. When it is necessary to remove the filtered impurities, simply unscrew the plug cap 23 and close the return water at the collector (installing a control valve at the return water connector at the collector is existing technology and will not be specifically described here). Since the filter screen 24 is located between the filter mounting hole 22 and the mixed water outlet connector 13, the mixed water in the distributor can flush out the impurities on the side of the filter screen through the filter mounting hole 22. The filter structure is simple in design and low in cost, making it easy to promote and use.

[0027] Furthermore, in order to improve the firmness of the filter structure installation, the filter mounting part 21 is provided with a mounting groove 26, in which the filter screen 24 and the positioning cylinder 25 are correspondingly installed.

[0028] Furthermore, in order to ensure the sealing of the mixing outlet 13 and the water distribution valve body 11 and the stability of the contact with the filter screen 24, the mixing outlet 13 is fixedly installed at the end of the water distribution valve body 11 by a fixing cap 27. An O-ring 28 is provided between the mixing outlet 13 and the end of the water distribution valve body 11, and the mixing outlet 13 abuts against the positioning cylinder 25 through the O-ring 28.

[0029] Furthermore, the inner diameter of the positioning cylinder 25 is larger than the inner diameter of the mixing outlet connector 13, so that the force of the mixing outlet connector 13 can be better applied to the positioning cylinder 25 through the O-ring seal 28, thereby improving the firmness of the filter screen 24 installation.

[0030] Furthermore, for ease of use, the water distribution valve body 11 is also equipped with a pressure gauge 29, an air vent valve 30, and a temperature measuring head 31.
