Problems solved by technology

However, for a double-tank water heater, since it has two inner tanks, the two inner tanks are connected and there are connecting brackets and other components, both the shape of the inner tank and the assembly of the water heater are more complicated than the single-tank water heater, and it is difficult to use a single-tank water heater. The installation method of the composite insulation board in the double-tank water heater is covered by the composite insulation board. Therefore, it is necessary to propose a thermal insulation structure setting method with good insulation effect and suitable for double-tank water heaters.

Embodiment 1

[0039] figure 1 The flow chart of the preparation method of the double-tank water heater that the embodiment of the present invention provides, as figure 1 As shown, the embodiment of the present invention provides a preparation method of a double-tank water heater, which not only facilitates the assembly of the double-tank water heater, but also improves the heat preservation effect of the double-tank water heater.

[0040] The preparation method of the double-tank water heater provided in this embodiment comprises the following steps:

[0041] Step S1: Prefabricate the composite insulation board 4.

[0042] figure 2 The structural representation of the composite insulation board and the inner container provided for this embodiment, as figure 2 As shown, the prefabricated composite thermal insulation board 4 is specifically: the outer periphery of the thermal insulation board 41 is foamed to form a specific shape and a foamed thermal insulation layer 42 covering the ther...

Embodiment 2

[0091] This embodiment provides a preparation method of a double-tank water heater, Figure 6The structural representation of the composite insulation board 4 provided for the embodiment of the present invention, as Figure 6 As shown, the preparation method of the double-tank water heater provided in this example is basically the same as that provided in Example 1, except that the shape of the prefabricated composite insulation board 4 in this example is different from that of Example 1. In this embodiment, the same steps or structures as those in Embodiment 1 will not be repeated.

[0092] Such as Figure 6 As shown, in addition to partially covering the straight section of the inner container 1 , the composite thermal insulation board 4 provided in this embodiment also partially covers both ends of the inner container 1 . Specifically, the composite thermal insulation board 4 provided in this embodiment includes an upper bladder thermal insulation portion 43 , a lower bla...

Abstract

The invention belongs to the technical field of water heaters, and particularly discloses a preparation method of a double-inner-container water heater and the double-inner-container water heater. Thepreparation method comprises the following steps that a composite insulation board is prefabricated; a shell and inner containers of the water heater are provided, wherein the inner containers comprise the upper inner container and the lower inner container, the composite insulation board and the inner containers are arranged in the shell, one face of the composite insulation board is in abuttingconnection with the bottom face of one side of the shell, and the other face of the composite insulation board at least partially cover the upper inner container; and foaming materials are injected into the shell for foaming filling of the space in the shell. The double-inner-container water heater is prepared by the preparation method. According to the preparation method of the double-inner-container water heater and the double-inner-container water heater, the insulation effect is good, and assembling is convenient.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a preparation method of a double-tank water heater and a double-tank water heater. Background technique [0002] The water heater is one of the necessary living appliances in modern homes. It mainly provides people with domestic hot water such as showers, which brings great convenience to people's lives. An electric water heater usually includes a shell, a liner set in the shell, and an electric heating device set in the liner. By energizing the electric heating device, the heat loss of the electric water heater is usually filled with polyurethane between the liner and the shell. Insulation materials such as a foam layer insulate the inner tank. [0003] The prior art discloses a water heater, which improves the heat insulation effect of the thermal insulation layer by arranging a composite thermal insulation board between the inner tank and the outer shell, wherein the co...
