Description

Anti-scald structure of multifunctional faucet

Technical Field

The utility model relates to a tap device, concretely relates to anti-scalding structure of multi-functional tap.

Background

A common stainless steel multifunctional water boiler faucet is generally provided with a single-channel silica gel inner tube, as shown in fig. 1 (cross-sectional view of the bent tube), boiling water flows through the silica gel inner tube 17, and mixed water flows through the outer wall of the silica gel tube and the inner wall 16 of the stainless steel bent tube.

Because the stainless steel has good heat conductivity, the stainless steel absorbs the heat of the mixed water along with the contact of the bent pipe and the mixed water, so that the temperature of the bent pipe is increased, and the highest temperature of the mixed water can reach 70 ℃. Namely, after the stainless steel absorbs heat, the stainless steel multifunctional water boiler tap has insufficient heat insulation performance and is easy to cause the risk of scalding.

SUMMERY OF THE UTILITY MODEL

In view of the above problems, the present invention is directed to a dual-channel multifunctional faucet anti-scald structure.

In order to realize the technical purpose, the utility model discloses a scheme is: the utility model provides an anti-scalding structure of multi-functional tap, includes inner tube and stainless steel outer tube, the inner tube is established inside the stainless steel outer tube, each other contactless between inner tube and the stainless steel outer tube, be equipped with the interlayer in the middle of the inner tube, the interlayer divide into hot water passageway and muddy water passageway with the inner tube, the inner tube coupling has hot water export and muddy water export, the interlayer middle part is equipped with two air separation holes.

Preferably, the hot water channel is connected with a heater and a cold water pipeline through a hot water valve core, and the cold water pipeline passes through the heater and reaches the hot water valve core.

Preferably, the mixing channel is connected with a hot water pipeline and a cold water pipeline through a mixing valve core.

Preferably, the mixing valve core is provided with a hot water through hole, a cold water through hole and a mixing water through hole.

Preferably, the inner tube is a silica gel inner tube.

The utility model has the advantages that: the utility model provides a binary channels silicone tube uses on the multi-functional water dispensers tap of stainless steel, realizes that the return bend of stainless steel water dispensers is kept apart with the water in the passageway, and the heat transfer of the water in two runners can be reduced in the air separation hole, solves the problem that the return bend generates heat. The utility model provides a structure is unique, can solve the contact of water with the metal, can make the stainless steel return bend not change along with the temperature of water, realizes cold and touches the function.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-4, a specific embodiment be an anti-scalding structure of multi-functional tap, including inner tube 1 and stainless steel outer tube 2, inner tube 1 is established inside stainless steel outer tube 2, each other contactless between inner tube 1 and the stainless steel outer tube 2, be equipped with interlayer 3 in the middle of the inner tube 1, interlayer 3 divides inner tube 1 into hot water passageway 4 and muddy water passageway 5, inner tube 1 is connected with hot water export 6 and muddy water export 7, interlayer 3 middle part is equipped with two air separated holes 8. This application has adopted the design of double-flow passage, and the inner tube interlayer divide into hot water passageway and mixes the water passageway, has increased two air separation holes between two runners in the inner tube, and the air separation hole can reduce the heat transfer of the water in two runners.

In specific implementation, the hot water channel 4 is connected with a heater 10 and a cold water pipeline 11 through a hot water valve core 9, and the cold water pipeline 11 passes through the heater and reaches the hot water valve core 9; the mixing channel 5 is connected with a hot water pipeline 12 and a cold water pipeline 11 through a mixing valve core 18.

The mixing valve core 18 is provided with a hot water through hole 13, a cold water through hole 14 and a mixing water through hole 15. The hot water through hole is connected with the hot water pipeline, the cold water through hole is connected with the cold water pipeline, and the mixed water through hole is connected to the mixed water channel after passing through the mixed water valve core.

This embodiment has preferentially adopted the silica gel inner tube, inner tube 1 is the silica gel inner tube, but not the restriction is this kind of material of silica gel, and other similar good materials of heat-proof quality all belong to in this application description.

The utility model provides a binary channels silicone tube uses on the multi-functional water dispensers tap of stainless steel, realizes that the return bend of stainless steel water dispensers is kept apart with the water in the passageway, and the heat transfer of the water in two runners can be reduced in the air separation hole, solves the problem that the return bend generates heat. The utility model provides a structure is unique, can solve the contact of water with the metal, can make the stainless steel return bend not change along with the temperature of water, realizes cold and touches the function.
