Description

Water inlet pipe for water heater

technical field

The utility model relates to the field of water heaters, in particular to a water inlet pipe for a water heater.

Background technique

At present, the water heater inlet pipes used by water heater manufacturers have some deficiencies: although the cold water is subject to greater resistance when flowing through the water inlet pipes, and the water flow speed is slowed down, the structure of the water inlet pipes has a great impact on the output of hot water in practical applications. The rate has a great influence, and usually cannot achieve a high hot water production rate.

Utility model content

The purpose of this utility model is to provide a water inlet pipe for a water heater to solve the problems raised in the above-mentioned background technology.

In order to achieve the above object, the utility model provides the following technical solutions:

A water inlet pipe for a water heater, comprising a pipe body, one end of the pipe body is a water inlet, and the other end is provided with a sealing plug; the pipe wall of the pipe body is provided with multiple groups of pipe body water outlet holes, each group of pipe body water outlet holes Evenly distributed along the circumferential direction of the pipe wall of the pipe body; a water-blocking sleeve is provided on the outside of the pipe wall of the pipe body, and the inner wall of the water-blocking sleeve does not overlap with the outer wall of the pipe body; the upper edge of the pipe wall of the water-blocking sleeve Several sets of outlet holes of the water-blocking casing are opened in the axial direction, and the outlet holes of the water-blocking casing are evenly distributed along the circumferential direction of the pipe wall of the water-blocking casing, and the outlet holes of two adjacent groups of water-blocking casings are staggered from each other; The unopened area on the wall completely blocks the outlet hole of the water blocking sleeve; the pipe body and the water blocking sleeve are made of stainless steel, copper or plastic; the inner wall of the water blocking sleeve and the outer wall of the pipe body are interference fit , connected by riveting, welding or high-efficiency adhesive bonding, the sealing plug and the inner wall of the pipe body are interference fit, and connected by riveting, welding or high-efficiency adhesive bonding; the progress of the pipe body There is a sheath on the outside of the pipe wall on the side of the nozzle, and the sheath and the pipe body are integrally formed by injection molding. The outer wall of the sheath and the pipe body is an interference fit; They are all interference fit and connected by riveting, welding and bonding; the outlet holes of the pipe body and the outlet holes of the water blocking casing are round holes with the same diameter.

Compared with the prior art, the beneficial effect of the utility model is: the utility model is provided with a sealing plug at the other end of the water inlet pipe, so that the incoming water flows back out from the wall of the water inlet pipe body after collision, and flows out from the pipe wall. The water flow collides with the inner wall of the water blocking casing, and then flows out from the water outlet hole on the water blocking casing. After being blocked twice, the flow rate of the water flow decreases, which reduces the interference of the water flow on the hot water inside the water tank and improves the production of hot water. out rate. At the same time, the water flows toward the bottom of the inner tank of the water heater, so that the cold water and the hot water are gradually mixed from bottom to top, further increasing the hot water output rate. The pipe body of the utility model is made of stainless steel, copper or plastic to avoid scaling on the surface of the outlet hole.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figures 1 to 4, a water inlet pipe for a water heater, including a pipe body 1, one end of the pipe body 1 is a water inlet, and the other end is provided with a sealing plug 3; Body water outlet holes 5, each group of pipe body water outlet holes 5 are evenly distributed along the circumferential direction of the pipe wall of the pipe body 1; It does not overlap with the outer wall of the pipe body 1; several groups of outlet holes 6 of the water blocking casing are provided in the axial direction on the pipe wall of the water blocking casing 2, and the outlet holes 6 of the water blocking casing are along the circumferential direction of the pipe wall of the water blocking casing 2 The outlet holes 6 of adjacent two sets of water-blocking sleeves are staggered from each other;

Further, the pipe body 1 and the water blocking sleeve 2 of the present invention are made of stainless steel, copper or plastic, and the surface will not be scaled. The inner wall of the water blocking sleeve 2 and the outer wall of the pipe body 1 are interference fit, which are connected by riveting, welding or high-efficiency adhesive bonding, and the sealing plug 2 and the inner wall of the pipe body 1 are interference fit. It is connected by riveting, welding or high-efficiency adhesive bonding to ensure the connection strength between the water blocking sleeve 2, the pipe body 1 and the sealing plug 3.

Further, a sheath 4 is fitted outside the pipe wall on the water inlet side of the pipe body 1 described in the present invention, and the sheath 4 is integrally injection-molded with the pipe body 1 to protect the pipe body 1 . Other known connection methods can also be used to ensure the interference fit between the sheath 4 and the outer wall of the pipe body 1 and sufficient connection strength.

Further, the water-blocking sleeve 2 and the pipe body 1 described in the present invention, and the pipe body 1 and the sealing plug 3 are all interference fit, or are connected by riveting, welding or bonding.

Further, the water outlet hole 5 of the pipe body and the water outlet hole 6 of the water blocking casing described in the present invention are both round holes with the same diameter, and the water flow velocity of each hole is basically the same.

In the utility model, the water flow entering the pipe body 1 first collides with the sealing plug 3 and flows back from the water outlet hole 5 of the pipe body, and then collides with the non-perforated area of the pipe wall of the water blocking casing 2 and folds from the water blocking casing water outlet hole 6 When it flows out, the flow rate of the water flow is reduced, which reduces the disturbance of the water flow to the hot water inside the water tank and improves the hot water output rate. At the same time, the direction of the water flow is also changed to flow towards the bottom of the water heater inner tank, so that the cold water and hot water are gradually mixed from bottom to top. , to further increase the hot water output rate.
