Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas cooker, and more particularly to a grill door.

[0002]

2. Description of the Related Art A conventional grill door device of this type has a structure in which a grill heating chamber 2 is located at the center of an operation panel portion 7 of a gas cooker as shown in FIG. The heated object tray 5 that is fastened can be pulled out from the inside of the grill heating chamber 2 to the front of the operation panel section 7.

The grill door device comprises a door 1 and a grill door handle 4. That is, a part of the grill door handle 4 is covered by the door frame 1a, and the glass door 1 that allows the object 6 to be heated in the grill heating chamber 2 to be recognized from the front of the operation panel portion 7 is fastened. Further, at the position where the object tray 5 to be heated is pushed into the grill heating chamber 2, the door 1 closes the grill heating chamber 2 to prevent the influence of heat on the operation panel portion 7.

[0004]

However, in the above-mentioned structure, the inside of the door is the grill heating chamber, so that the entire door becomes extremely hot during use of the grill. Further, since the upper part of the door is located higher than the object to be heated, when handling the object to be heated during cooking, there is a possibility that the hand may come into contact with the upper end surface of the door, and if touched, there is a problem of being burned. Was.

SUMMARY OF THE INVENTION The first object of the present invention is to provide a grill door device which prevents burns caused by a hand touching the door during cooking.

A second object is to further reduce the temperature of the portion above the heat insulating material that may come into contact with the human hand.

[0007]

In order to achieve the first object, the grill door device of the present invention comprises a grill heating chamber,
The heated object tray on which the food is placed, the grill door handle fastened to the heated object tray, and the door of the grill heating chamber fastened to the grill door handle,
A heat insulating material is provided on the door.

In order to achieve the second object, the present invention provides a heat insulating material having a convex projection at a predetermined portion.

[0009]

In the grill door device of the present invention, by providing the heat insulating material on the upper end surface of the door, it is difficult for heat to be transferred to this portion by heat conduction. If so, you can prevent burns.

Further, by providing a convex shape on a part of the heat insulating material, the contact area between the heat insulating material and the hand can be reduced even when the heat insulating material comes into contact. Further, since the convex shape is in contact with the hand, the heat capacity of the convex section is small, and the surface area of the heat insulating material is large compared to its volume.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, the grill heating chamber 2 is
It is provided in the center of the operation panel unit 7. The object to be heated 6 is placed on the object to be heated receiving tray 5 fastened to the grill door handle 4, and the grill heating chamber 2 is slid in and out. The grill door device is provided with a glass door 1 so that the object 6 to be heated in the grill heating chamber 2 during cooking can be seen from the front side of the operation panel section 7. Further, a rubber-like heat insulating material 3 is provided on the upper end surface of the door 1. FIG. 3 is a partially enlarged view showing the configuration of the door 1 and the heat insulating material 3. A rubber-like heat insulating material 3 having a U-shape is provided with an inward projection 3 b at one end thereof, and the glass door 1 It hangs on the end surface 1b of the door frame 1a for the purpose of reinforcing. Further, a triangular protrusion 3a is provided on the upper surface of the heat insulating material 3.

In the above construction, the heat during grill cooking mainly heats the object to be heated by convection and radiation, and simultaneously heats the grill door device. Due to this heat, the metal door frame 1a provided on the inner surface of the grill door 1 has a small specific heat, so that the temperature thereof rapidly rises in a short time. Further, since the heat insulating material 3 provided on the upper end surface of the door 1 is located at the corner of the grill heating chamber 2 during cooking, it is hardly affected by convection and radiation. Therefore, the temperature rise of the heat insulating material 3 is mainly caused by the door frame 1
It depends on the heat transfer from a. However, since this portion is made of the heat insulating material 3 that does not easily transfer heat, the temperature of the upper end portion of the heat insulating material 3 that the hand touches is unlikely to rise.

Further, in the present invention, the shape of the heat insulating material 3 is a convex shape in which the upper end portion, which is easily touched by a person, is narrowed. This is because the convex section has a small cross-sectional area, so that the amount of heat transfer due to heat conduction is reduced, and when the grill door handle 4 is pulled out from the grill heating chamber 2, the convex section has a large volume. Is small (the heat capacity is small), so that heat is radiated and the temperature is easily lowered.

Comparing the temperature of the upper end of the grill door 1 of the present invention and the conventional gas cooker, in the conventional gas cooker, the temperature of the upper end of the grill door 1 after 20 minutes of grill cooking is about 20.
It was 0 ° C. On the other hand, in the gas cooker of the present invention, the temperature of the heat insulating material at the upper end of the grill door 1 is about 14 after 20 minutes of grill cooking.
At 0 ° C., and when it was pulled out from the grill heating chamber 2, the temperature suddenly dropped to 60 ° C. or lower. In the conventional gas cooker, it took a considerable time to reach a temperature of 100 ° C. or lower even when it was pulled out from the grill heating chamber 2.

From the above description, it is understood that in the structure of the present invention, the temperature of the upper end portion of the grill door 1 is hard to rise and is easy to cool. Therefore, during or after cooking, when the heated object tray 5 is pulled out to the front of the operation panel section 7 and the non-heated object 6 is handled, even if the hand touches the upper part of the door 1, it is difficult to cause burns. .

Further, since the heat insulating material 3 is a rubber molded product and the U-shaped one end 3b is hooked on the end surface 1b of the door frame 1a, even if dirt from the object 6 to be heated adheres, the heat insulating material 3 shown in FIG. It can be removed from the door 1 and washed as shown. Further, there is an effect that it is securely fixed even when it is attached.

Next, another embodiment of the present invention will be described with reference to FIGS. 5, 6 and 7. 5 is different from the above embodiment in that the heat insulating material 3 made of plastic is fixed to the door frame 1a with screws 11. 6 is different from that of the above-described embodiment in that the heat insulating material 3 has a spring-like stopper 12 whose ends are squeezed and whose ends are squeezed inward.
Since it is fixed to the door frame 1a, according to these configurations, a material having high hardness can be used as the heat insulating material 3, decoration such as coloring can also be performed, and the range of material selection can be widened. There is.

7 is different from the above embodiment in that
The heat insulating material 3 is directly bonded to the glass door 1 with the adhesive 10. According to this structure, the shapes of the door 1 and the heat insulating material 3 can be simplified, and the fixing is reliable. It has the effect of good assembly.

[0020]

As described above, according to the grill door device of the present invention, the following effects can be obtained.

(1) Since the heat insulating material is provided on the upper portion of the grill door, there is an effect that the temperature rise is low and even if a hand comes in contact with the grill door during cooking of the grill, burns can be prevented.

(2) By forming the triangular protrusions on the upper surface of the heat insulating material, it is possible to lower the temperature of the upper surface of the heat insulating material which may be touched by the hand during grill cooking.
