Abstract

The utility model relates to a water feeder of a horizontal water tank underneath-type water inlet device of a water-storage heater, having the characteristics of not only changing the cold water inlet direction by altering tap-water from up-thrust into cross-flow, but also eliminating the pipeline siphon phenomenon by using an eyelet on a caecal tube in the water feeder when the user's tap water network pressure decreases or water is cut-off. Further, the length of the water feeder can directly reach the top of the inner container, thus the lowest liquid level in the water tank becomes the top end which is the top of the inner container, and the whole tank of water is preserved. This one-way channel without outlet function can effectively prevent the water in the water tank from flowing backward through the water inlet tap.

Description

A kind of unidirectional water inlet device

Affiliated technical field

The utility model relates to the underneath type water feed apparatus of the horizontal water tank of storage water heater.

Background technology

Storage water heater's underneath type water inlet water nozzle is in the bottom of water tank, and running water orthoscopic is mixed hot and cold water and influenced the water temperature of hot water toward upper punch when preventing water into, and people have designed the water inlet device.Common water inlet device only changes the direction of cold water water inlet, makes running water become crossing current by upper punch.When user's running water network of rivers pressure reduces or cuts off the water, the function that the without hindrance sealing case of this class water inlet device water itself flows backwards away from the water inlet water nozzle.

Summary of the invention

The utility model provides a kind of underneath type water inlet device, and purpose is when pressure of water network reduces or cuts off the water, and can stop the water of water heater the inside to flow backwards away from the water inlet water nozzle.

The technical scheme that its technical problem that solves the utility model adopts is: the water inlet device is made " two sleeve pipe " form, interior pipe is water inlet pipe, outer tube is the blind pipe of a sealing and the higher authorities that cover on water inlet pipe, an aperture is worn to cut off the pipeline siphon in the position, top of blind pipe, the apopore of cold water along blind pipe inwall gap from bottom enters inner bag in the water inlet pipe, and the length of water inlet device is good with the top of through inner bag.Like this, when cutting off the water, the water of the trace that only flows away from the water inlet water nozzle of water heater is because liquid level is by the height decision of water inlet device in the water tank.

The beneficial effects of the utility model are that the water inlet device in the insertion water tank water intake water nozzle has possessed the half-duplex channel function of only import but no export, can prevent effectively that the water in the water tank from flowing backwards away from the water inlet water nozzle.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the water inlet device of being located by sealing shroud between blind pipe and the water inlet pipe;

Fig. 2 has bearing support to fix the water inlet device of water inlet pipe in blind pipe the inside;

Fig. 3 is water inlet devices of being nested together then of flange of blind pipe and water inlet pipe.

Among the figure, 1. blind pipe; 2. water inlet pipe; 3. aperture; 4. apopore; 5. sealing shroud; 6. bearing support.

The specific embodiment

In Fig. 1, the length of blind pipe (1) and water inlet pipe (2) are similar, have aperture (3) at the position, top; Have one or several apopore (4) on its tube wall, the distance of apopore (4) and blind pipe (1) end is less than the diameter of inner water tank.The length of water inlet pipe (2) approaches or equals inner bag diameter and water nozzle length sum, inserts the through top of blind pipe (1) during assembling, and embed sealing shroud (5) between port position and blind pipe (1).

In Fig. 2, the length of blind pipe (1) is less than the diameter of inner water tank, and the position, top has aperture (3); There is not apopore on the tube wall; Bearing support (6) is housed in the pipe.Length such as Fig. 1 of water inlet pipe (2) insert through blind pipe (1) top in the bearing support (6), and port position can flange, and embeds sealing shroud (5) between the water tank water nozzle.

In Fig. 3, except blind pipe (1) and water inlet pipe (2) were located by flange, all the other were as Fig. 1.

Claims

1. two telescopic unidirectional water inlet device, it is characterized in that: blind pipe (1) covers on the outside of water inlet pipe (2), go directly blind pipe (1) in the end of blind pipe (1) of water inlet pipe (2).

2. water inlet device according to claim 1 is characterized in that: the end of blind pipe (1) has aperture (3).

3. water inlet device according to claim 1 is characterized in that: have one or several apopore (4) on the tube wall of blind pipe (1).

4. water inlet device according to claim 1 is characterized in that: do not have apopore on the length of blind pipe (1) its tube wall less than the inner water tank diameter.

5. water inlet device according to claim 1 is characterized in that: bearing support (6) is equipped with in the inside of blind pipe (1).
