Abstract

The invention discloses a water mixing structure of a novel water mixer, which consists of a central fixing device 101, a cold and hot water interlayer 102 and an outer wall support 103, wherein a plurality of spiral tracks are arranged on the outer wall of the central fixing device 101, and two circles of bulges are arranged below the tracks; the outer wall of the cold and hot water separation layer 102 is provided with a plurality of spiral tracks which are opposite to the rotating direction of the central fixing device, and the outer wall support 103 is provided with two circles of bulges. Hot water enters an inner cavity of the water mixing device through a 104 pipeline port and rotates and moves downwards along a spiral track of the central fixing device, and cold water enters an outer cavity of the water mixing device through a 105 pipeline port and rotates and moves downwards along a spiral track of the supporting outer wall; hot water flows through the spiral track and then is mixed with cold water under the action of centrifugal force, and when the cold water and the hot water flow through the two bulges of the central fixing device and the outer wall supporting device, the cold water and the hot water are further mixed. The water mixing structure of the water mixer can realize the full mixing of cold water and hot water, and can be widely assembled in water mixers in industries such as showers, hotels and the like.

Description

Novel water mixing structure of water mixer

Technical Field

The invention relates to a fluid mixing device, in particular to a water mixing structure of a water mixer for mixing cold water and hot water.

Background

With the development of society, the temperature of hot water supplied by a hot water supply system is continuously increased, however, hot water at the outlet of a boiler cannot be directly used, and a water mixer is needed to obtain warm water with a specific temperature for use. Particularly, in large bathing places, warm water with constant temperature needs to be provided by a water mixer; however, the existing water mixer has the disadvantages of low reliability, slow heat exchange speed, poor water mixing effect, low efficiency and unstable temperature of output warm water, so that shower water is cold and hot, and is very uncomfortable.

Disclosure of Invention

In order to overcome the defects of the water mixer in the existing large-scale bathing place, the invention aims to provide the water mixing structure of the water mixer, which has the advantages of high heat mixing speed, high water mixing efficiency and stable temperature of output warm water.

In order to achieve the purpose, the invention adopts the following technical scheme:

a water mixer comprises a central fixing device, a cold and hot water interlayer and an outer wall support, wherein a plurality of spiral tracks are arranged in the circumferential direction of the outer wall of the central fixing device, and two circles of bulges are arranged below the tracks; the cold and hot water separation layer covers the central fixing device, the inner wall of the cold and hot water separation layer is attached to the spiral track on the central fixing device and has no gap, and a plurality of spiral tracks with the direction opposite to that of the spiral track on the outer wall of the central fixing device are arranged in the circumferential direction of the outer wall of the cold and hot water separation layer; the outer wall is supported and covered on the cold and hot water interlayer, the inner wall of the outer wall is attached to the spiral track on the outer wall of the cold and hot water interlayer and has no gap, and two circles of bulges are arranged at the lower part of the matching surface.

Compared with the prior art, the method has the following advantages:

compared with the existing water mixing structure of the water mixer, the water mixer has the advantages of small volume, high heat exchange speed, high water mixing efficiency and smaller temperature fluctuation of output warm water under the same input condition.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

As shown in fig. 1, a water mixing structure of a water mixer mainly comprises a central fixing device 101, a cold and hot water interlayer 102 and an outer wall support 103, and fig. 2 is a structural schematic view of the central fixing device, wherein a plurality of spiral tracks 201 are arranged in the circumferential direction of the outer wall of the central fixing device, and two circles of protrusions 202 are arranged below the tracks; FIG. 3 shows a cold and hot water separation layer covering the central fixing device, the inner wall of which is fitted with the spiral track 201 on the central fixing device without a gap to form a closed spiral track, and a plurality of spiral tracks 302 are arranged on the outer wall 301 of the central fixing device in the circumferential direction, which is opposite to the direction of the spiral track on the outer wall of the central fixing device; fig. 4 is a schematic view of an outer wall support structure, which covers the hot and cold water separation layer, and the inner wall of the outer wall of the hot and cold water separation layer is jointed with the spiral track 302 on the outer wall of the hot and cold water separation layer without a gap, so that a reverse closed track is formed, and two circles of protrusions 401 are arranged at the lower part of the matching surface.

As shown in fig. 1, hot water moves spirally downward through the mixer inlet 104 along a closed spiral track formed by the central fixture and the hot and cold water spacers; cold water moves downwards spirally along a reverse closed spiral track formed by the cold and hot water isolation layer and the outer wall support through the water mixer input port 105; when the hot water and the cold water are separated from the track at the same time, the hot water moves outwards under the action of centrifugal force, the cold water rotates under the action of centrifugal force and the outer wall, so that the cold water and the hot water are mixed with each other, and then the cold water and the hot water are further fully mixed under the action of the protrusions 202 and the protrusions 402 and are output through the output port 106.
