Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a housing structure of a liquid fuel combustion device, and particularly to the shape of a molded product provided with an operation panel and attached to the housing.

[Prior Art] Figure 2 is a exploded cross-sectional view showing the entire structure of a liquid fuel combustion device. In the figure, (1) is a housing, (2) is a bottom plate, (3) is a carburetor, and (4) is a fuel Tank, (5) is oil pan, (6)
is the heater, (7) is the oil pump, (8) is the oil pipe,
(9) is a thermistor, (10) is a needle pipe, (1
1) is a solenoid valve, (12) is a flame hole plate, (13) is a flame rod, (14) is a spark plug, (15) is a combustion chamber, (
16) is a blower, (17) is an overheating prevention device, (18) is a board, and (19) is an operation panel.

A fuel tank (4) that supplies liquid fuel to the vaporizer (3) is detachably installed in an oil pan (5), and the vaporizer (3) is equipped with a preheating heater ( 6) is cast, and the temperature of the vaporizer (3) is monitored by a thermistor (9). An oil pump (7) is provided on the oil pan (5), and liquid fuel is supplied to the vaporizer (3) via an oil pipe (8).
A needle with one end connected to a solenoid valve (11) is built into the inside of the fuel cell 0), and the structure is such that liquid fuel is spouted into the vaporizer (3) by opening and closing a hole at the tip.

A flame hole plate (12) is attached to the top surface of the vaporizer (3), and a flame detection rod for detecting flame and a spark plug (14) for ignition are provided on the side surface.

Then, a combustion chamber (15) is formed to surround the carburetor (3).
) is formed, and a blower (16) for introducing cold air from outside the machine is installed at the rear of the combustion chamber (15). A superheat prevention device (17) is attached to the upper part of the combustion chamber (15) to prevent the inside of the machine from becoming abnormally high temperature.

The operation panel (19) is provided with an operation section and a display section, and when the operation panel (19) is operated, the control circuit in the board (18) is activated, heating operation is started, and the oil pan ( Fuel is pumped up from 5) by an oil pump (8), and the solenoid valve (11) is opened to inject the fuel into the carburetor (3). The ejector effect temporarily blows air into the ejected fuel, creating a mixture.
The heater (6) turns the wall surface into vaporized combustion gas in the vaporizer (3), which is preheated to approximately 200 to 300°C, and the flame hole plate (12)
It is emitted into the combustion chamber (15) through a hole drilled in the flame hole plate (
12) Form a combustion flame on top.

FIGS. 3 and 4 are perspective views showing the housing structure of a conventional liquid fuel combustion device. The structure shown in FIG. Operation panel (19)
It has a structure in which a molded product with a
Figure (B) is a diagram showing the appearance seen from the back.

The structure shown in Fig. 4 is a structure in which a molded product with an operation panel (19) is attached to a part of the upper case (1b) constituting the housing (1). (A> is a diagram showing the appearance seen from the front, and FIG. 4(B) is a diagram showing the appearance seen from the back.

[Problems to be Solved by the Invention] As described above, in the case structure of the conventional liquid fuel combustion device, the molded product provided with the operation panel is placed on a part of the front surface of the case or on the top surface of the case. There are problems in that it is used only in a limited number of areas, is subject to design restrictions, and has poor product strength.

In other words, if the top surface of the product is not a molded product that can be freely formed into a curved shape, there will be significant design constraints, and using a molded product only for the front or part of the top of the casing is prohibited. There was a problem in that the strength of the molded product (including the strength of the adhesive and the operation panel) was significantly inferior.

This invention was made in order to solve such problems, and is a liquid fuel combustion device that makes full use of the characteristics and properties of molded products and can improve product strength and design with a simple structure. The purpose is to obtain a housing structure.

f Means for Solving the Problem] The casing structure of the liquid fuel combustion device according to the present invention is such that the molded product provided with the operation panel has a shape that integrally covers the entire periphery of the top surface of the casing. That is.

[Function] In the liquid fuel combustion device of the present invention, the shape of the molded product provided with the operation panel is such that it integrally covers the entire periphery of the top surface of the casing, so the top surface of the casing has a curved shape. The strength of the molded product (including the adhesive strength and the strength of the operation panel) can be improved by allowing the molded product to integrally cover the entire periphery of the casing. .

[Example] An example of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing an embodiment of the present invention, FIG. 1(A) is a diagram showing the appearance seen from the front, FIG. 1(B) is a diagram showing the appearance seen from the back, and FIG. (C) is a diagram showing a cross section taken along the line M-M shown in FIG. ), (lb) is the upper case of the housing (1), (19) is the operation panel, (20) is the molded product in this example, and the entire peripheral area of the upper surface of the housing (1) is integrated. It has a cover shape, and an operation panel (19) is mounted on top of it.
The operation panel (19) has a double-layer molded structure with increased strength.

With this structure, the top surface of the product can be freely formed into a curved shape and the color can be freely selected, eliminating restrictions on product design and creating a structure with increased strength. .

Note that the operation is similar to that of the conventional device.

[Effects of the Invention] As explained above, in this invention, the shape of the molded product provided with the operation panel is such that it integrally covers the entire periphery of the top surface of the casing, so the top surface of the casing is curved. This has the effect of increasing strength and making it possible to obtain a housing structure with an excellent design.
