Description

Quick detachable air energy water heater tank with built-in coil

technical field

The utility model relates to a water heater, in particular to a quickly detachable air energy water heater water tank with a built-in coil. the

Background technique

At present, the built-in coil water tanks of air energy water heaters have been placed in the tank liner and then welded and sealed, or the coils are connected to flanges and placed in the water tank liner for bolt fixing and sealing. The tank liner and coil are both Install from the bottom of the water tank, so the product has a lot of defects. This assembly method is not flexible enough. During use, the coil has abnormalities (severe scaling, rot, etc.), and cannot be disassembled and repaired on site. It needs to be repaired by the product manufacturer. It is very inconvenient to overhaul the water tank in the later stage, and even cause the entire water tank to be scrapped, causing heavy losses. the

Contents of the invention

The utility model aims to solve the above-mentioned shortcomings of the prior art, and provides a quick dismountable air-energy water heater tank with a built-in coil. The coil is built into the inner tank and fixed by bolts, which is convenient for disassembly during maintenance, and the installation is firm. , good sealing. the

The utility model adopts the technical scheme to solve the technical problem: the air-energy water heater water tank with built-in coil of quick disassembly type includes an inner tank and a coil built in the inner tank, and the inner tank is provided with a water inlet pipe and a water outlet pipe. The opening of the liner is equipped with a flange, a sealing ring, and a tie rod. The coil is fixed on the flange, and the flange is fixedly connected to the tie rod through the tie rod bolt. A detachable thermal insulation cotton is arranged outside the pull rod, and an end cover is arranged outside the thermal insulation cotton. The welding parts of the recessed flange and coil are recessed, and they are installed from the top of the water tank, which is safe, convenient, effective and has better sealing performance. The installation is more convenient and the efficiency is improved. the

The liner is in the shape of a barrel. The barrel shape is easy to process and has a large volume. the

There are two pressure rod bolts. Fixing the pull rod on the inner tank of the water tank, compared with the past with eight bolts, saves material and assembly time, is safe and effective, and improves efficiency. the

The beneficial effect of the utility model is: the utility model realizes the detachable way of the built-in coil assembly of the water tank of the air energy water heater, which not only solves the problem of inconvenient assembly and maintenance of the water tank of the traditional air energy water heater, but also improves the efficiency of the water tank of the air energy water heater. safety and assembly efficiency. the

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

With reference to accompanying drawing: this quick detachable air-energy water heater water tank with built-in coil includes an inner tank 9, a coil 6 built in the inner tank 9, and the inner tank 9 is in the shape of a barrel. The inner tank 9 is provided with a water inlet pipe 10 and an outlet pipe 11, and the opening of the inner tank 9 is provided with a flange 5, a sealing ring 4, and a pull rod 8. The coil 6 is fixed on the flange 5, and the flange 5 passes through the Pull rod bolt 7 is fixedly connected on the pull rod 8, and pull rod 8 is fixed on the liner 9 by pressure rod bolt 3, and is provided with detachable insulation cotton 2 outside pull rod 8, and heat insulation cotton 2 is provided with end cover 1 outside. Wherein there are two strut bolts 3.

When assembling, first put the coil 6 and the recessed flange 5 into the inner tank 9 as a whole, and then put in the sealing ring. The sealing ring adopts a buckle-type annular silicone rubber ring. Fix it on the pull rod 8, then install and fix the pull rod 8 on the inner tank 9 through the pressure rod bolt 3, put in the detachable thermal insulation cotton 2, and finally cover the detachable end cover 1 to complete the assembly of the water tank. the

The utility model realizes the detachable way of the built-in coil assembly of the water tank of the air energy water heater, which not only solves the problem of inconvenient assembly and maintenance of the water tank of the traditional air energy water heater, but also improves the safety and assembly efficiency of the water tank of the air energy water heater. the

Although the present invention has been illustrated and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made within the scope of the claims. the
