The water storage type water heater comprises the water inlet pipe. According to the water storage type water heater and the water inlet pipe thereof, the axis of the outer sleeve is arranged to deviate from the axis of the middle water pipe, the local clearance between the outer sleeve and the middle water pipe is larger than the clearance when the outer sleeve and the middle water pipe are arranged concentrically, and therefore the clearance is prevented from jamming due to water scales, and water flowing out from a water outlet pipe is guaranteed.

Description

Storage-type electric water heater and water inlet pipe thereof

Technical field

The utility model relates to field of water heaters, in particular to a kind of storage-type electric water heater and water inlet pipe thereof.

Background technology

A lot of water inlet pipes of water heater use have now all adopted the structure of certain buffering current; As adopt oppositely to change the direction of a stream of water and control speed and the pressure that water flows out; Make cold water concentrate on the water heater liner bottom; Can alleviate mixing between the hot water that has heated in bottom cold water and the water heater liner like this, the heat of the least possible absorption water heater, the temperature that the least possible reduction inner bag is interior.As shown in Figure 1; General employing all is the center that middle water pipe 10 is positioned over outer layer sleeve 20 in the prior art; Middle water pipe and outer layer sleeve have uniform gap 30; Water inlet pipe is fixed on the water heater liner through fixture 40, and cold water gets into water inlet pipe along direction shown in the S1, flows out along the S2 direction.Because middle water pipe 10 and outer layer sleeve 20 concentric installations so just cause, or be to guarantee that the gap 30 of middle water pipe and outer layer sleeve is suitable; The outer layer sleeve diameter is bigger, influences water inlet pipe and installs, and causes the inner bag tube connector bigger; Improved cost, influenced production technology, such as welding or the like; For guaranteeing the water inlet pipe installation, although middle water pipe and outer layer sleeve gap are even, the gap is less; And less clearance can cause when water quality is bad, and service time is long slightly; The gap of water pipe is the situation on stifled by incrustation scale, causes water outlet difficulty, the problem of water outlet not even.

The utility model content

The utility model aims to provide a kind of storage-type electric water heater and water inlet pipe thereof that prevents that the gap between middle pipe outer wall and the outer layer sleeve inwall from stopping up.

The utility model provides a kind of storage-type electric water heater water inlet pipe, comprising: middle water pipe and the outer layer sleeve that is set in the middle water pipe outside have the gap between middle water pipe and the outer layer sleeve; One end of middle water pipe is provided with the fixture that is fixedly connected with water heater liner, and middle water pipe is away from an end and the gap conducting of fixture; Outer layer sleeve is away from the mouth of pipe sealing of an end of fixture; The axis setting of water pipe in the middle of the axis runout of outer layer sleeve.

Further, middle water pipe is fixedly connected with outer layer sleeve away from an end of fixture, and middle water pipe is provided with the through hole with the gap conducting away from the sidewall of an end of fixture.

Further, outer layer sleeve is near being provided with seal between end of fixture and the middle pipe outer wall; The sidewall near an end of fixture of outer layer sleeve is provided with a plurality of along its apopores that circumferentially distribute.

Further, the outside of the distributed areas of a plurality of apopores is arranged with conical sleeve; The top and the outer layer sleeve of conical sleeve are tightly connected, and surround delivery port between the bottom edge of conical sleeve and the outer layer sleeve, and the cavity between conical sleeve and the outer layer sleeve forms cushion space.

Further, conical sleeve adopts bonding, as to be spirally connected perhaps clamping mode to be connected with outer layer sleeve.

Further, middle water pipe is an insulation tube.

The utility model also provides a kind of storage-type electric water heater, comprises aforesaid storage-type electric water heater water inlet pipe.

Storage-type electric water heater and water inlet pipe thereof according to the utility model; Because the axis setting of water pipe in the middle of the axis runout of outer layer sleeve; Thereby the gap when local gap between outer layer sleeve and the middle water pipe is installed with middle water pipe is concentric greater than outer layer sleeve; Thereby prevent that the gap from being stopped up by incrustation scale, guarantee the outlet pipe water outlet.
