Description

[Detailed explanation of the idea] The present invention relates to a cooker equipped with a safety guard.

In general, cooking appliances such as hot plates are known to have guard metal tubes on both sides of the main body to prevent burns from coming into contact with the heated plate body during use. There is.

These are connected and supported at both ends of the gripping portion of the main body which also serves as a support stand.

However, since the conventional metal tube a is tightly fitted and supported in the recess C of the grip part C as shown in FIG. 7, the grip part may be damaged due to expansion and contraction of the instrument body due to temperature differences. Alternatively, it has the disadvantage that the tube itself may become loose.

As a countermeasure for this, there is a method in which a spring d is interposed as shown in Figure 8, but this can absorb the looseness, but since the metal tube a is hollow, the spring d
is bent and does not work properly.

Furthermore, as shown in Fig. 9, it is possible to apply a uniform pressure to the end face of the metal tube a by interposing a washer e, but this requires a separate member such as the washer e and has the problem of impairing workability. ing.

The present invention was developed to solve the above problem, and by arranging a spring having a protrusion for guiding the metal tube in a recess that receives the end of the metal tube, the protrusion fits inside the metal tube when connecting. It is an object of the present invention to provide a cooking appliance which serves as a guide when the appliance main body expands and contracts, receives uniform axial biasing force from a spring, and improves assembly workability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, details of the present invention will be explained with reference to the drawings for one embodiment.

Reference numeral 1 denotes a dish-shaped instrument body with grips 2.2 provided at both ends in the longitudinal direction, and a heating element 3 is housed in the bottom.

The grip portion 2 is formed integrally with support legs 4 that support the main body 1.

Reference numerals 5 and 5 denote metal tubes for safety guarding, which connect the gripping parts 2 and 2 and are arranged on both sides of the main body 1 in the width direction.

This metal tube 5 is inserted into four parts 6 formed at each end of the grip part 2, and is further supported via a spring 8 having a guide protrusion 7 at one end as shown in the third figure.

9 is a temperature control plug. Next, we will discuss the effect.

The metal tube 5 has a protrusion 7 whose outer diameter is equal to the inner diameter of the tube, which is bent at one end of the spring 8 in its open end. It will be pressed with a strong biasing force.

Therefore, when the metal tube 5 is inserted into the recess 6 of the grip part 2 through the intervention of the spring 8 having such a protrusion 7, the metal tube 5 is subjected to an even biasing force along the axial direction, so that the instrument is not easily attached during use. Even if the main body 1 expands or contracts, the movement will be smoothly guided by the protrusion 7 and absorbed by the elasticity of the spring 8, so that the grip 2 will not be subjected to undesired force and will not writhe. It has an excellent effect without causing any stickiness.

As described in detail above, the present invention provides a cooking appliance in which a guard metal tube is supported between the gripping parts, in which the gripping part that connects the metal tubes is provided with four parts that receive the ends of the pipes, and the metal tube is placed in the recessed part. Although this cooker is equipped with a spring that has a protrusion for guiding, the main body of the cooker expands due to temperature differences.
Since contraction is guided by the protrusion of the spring and absorbed by smooth movement along the axis of the recess, damage and rattling can be prevented, and furthermore, parts such as washers are not required, making assembly work easier. It has the special advantage of improving
