Problems solved by technology

However, according to the coating method of the transfer method, a plate for transfer is required, resulting in high cost.
In addition, it is not suitable for large-area finishing
[0008] On the other hand, the finish applied to the exterior shell is easily damaged by wind, rain, or sunlight including ultraviolet rays, and is prone to staining or discoloration

Embodiment Construction

[0035]Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

[0036]First, in order to be readily understood, the outer casing C of the warm water unit used by the manufacturing method of the present embodiment is used as the structure of the warm water unit U of the outer casing C for the warm water unit.

[0037]inFigures 1a to 2b In the middle, the warm water unit U corresponds to the hot water supply device, including the outer casing C, and contains warm water equipment 1 for warm water in the outer casing C. The warm water device 1 includes a heat exchanger 10 flowing through hot water for heating a combustor 11 that is heated in the heat exchanger 10, and a fan (FAN) that supplies the burning air to the burner 11. 12.

[0038]The outer casing C includes a rectangular case-shaped outer casing body 2 having an opening portion 20 on the front surface, and a cover 3 (front cover) that blocks the opening portion 20. The c...

Abstract

This method of manufacturing an outer case for a hot water unit involves a pressing step for subjecting a flat metal plate (30a) to press processing to form a component part (3) of the external case (C), and a painting step for painting letters, symbols, diagrams or patterns on the component part (3), wherein the painting step involves an inkjet printing step for forming an inkjet printing layer (4) by performing inkjet printing on the flat metal plate (30a). The pressing step is performed after the inkjet printing step, and after the pressing step, there is further a clear-coating step for forming a clear layer (5) on the inkjet printing layer (4). Through this configuration, even when a complex pattern is added to the outer case for the hot water unit, it is possible, with simple work processes, to suitably manufacture the outer case (C) with good productivity and at low cost.

Description

Technical field[0001]The present invention relates to a method for producing a three-shelling housing for the manufacture of a warm unit. The warm water unit is, for example, a hot water supply device or a thermoelectric system, or the like, which is contained in the outer casing for the hydrothermal water equipment for warm water production or warm water.Background technique[0002]Specific examples of the heated water unit constituting the hot water supply device, a warm water such as a thermos hydraulous device that is heat-heated by the combustion gas generated by the burner (Burner) is housed in a warm water unit in the outer shell (for example, refer to Patent Document 1 ~ Patent Document 3). The exterior housing for such warm water units is usually used to perform the surface of the monochrome color steel plate to produce the surface.[0003]In such a warm water unit, in addition to the text / mark of the vendor name, type, or capabilities such as the warm water unit, sometimes i...
