Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a handle device for an oven, a stove with a grill, and other cooking appliances.

(Prior Art) Conventionally, in a heating cooker that includes a heating chamber inside the cooking device body and a door with a handle at the front opening of the heating chamber, a heating chamber is provided in order to reduce the influence of heat from the heating chamber. It is known that the handle is disposed on the outer surface of the cooking device with a gap therebetween.

(Problem to be solved by the invention) However, with the above-mentioned conventional device, the handle is heated by radiant heat from the door and the cooker body, causing a large temperature rise, and the handle becomes hot, causing the door to open and close. There were inconveniences such as it becoming difficult to remove and the entire handle deteriorating due to heat.

(Means for Solving the Problems) The present invention aims to provide a handle device that eliminates the above-mentioned inconveniences, and includes a heating chamber in the main body of the cooker, and a handle attached to the front opening of the heating chamber. In a heating cooker comprising a door with a door, the handle is disposed on the outer surface of the heating cooker with a gap, the surface of the handle facing the outer surface of the heating cooker is heated. It is characterized by being formed on the reflective surface of.

(Function) The present invention has the above-mentioned configuration, and according to this, heat is radiated from the door and the cooker body toward the handle, especially when the heating cooker is in use, but the radiant heat is absorbed by the reflective surface of the handle. Because of the reflection, the temperature rise of the handle is small, and therefore the handle portion of the handle is always maintained at a low temperature.

(Example) Next, an example of the present invention will be described based on the drawings.

In Figs. 1 to 5, 1 is the cooking device main body 2.
A gas heating cooker comprising a heating chamber 3 inside and a combustion chamber 5 having a burner 4 as a heat source inside the heating chamber 3, and a front opening of the heating chamber 3 provided with a front-loading door 6 that can be opened and closed. The heating chamber 3 is provided with a circulation fan 7 at the rear thereof, and an exhaust port 9 connected to an exhaust pipe 8 at the rear top of the heating chamber 3.

In the figure, reference numeral 10 indicates a handle disposed with a gap above the front surface of the door 6, which is the outer surface of the gas oven 1, in order to reduce the influence of heat from the gas oven 1.

The gas oven 1 configured as described above operates the burner 4 for combustion and drives the circulation fan 7 to transfer high-temperature hot air generated in the combustion chamber 5 to the heating chamber 3.
The hot air is guided inside and circulated to heat the food to be cooked in the heating chamber 3, and a part of the hot air is released as combustion exhaust to the outside via the exhaust port 9 and the exhaust pipe 8. During use, the heating chamber 3 becomes hot, so even though the handle 10 is placed above the front surface of the door 6 with a gap, the handle 10 absorbs radiant heat from the door 6, which is the outer surface of the gas oven 1. The handle portion 10a is heated and the temperature rises significantly, and the handle portion 10a becomes unfavorably hot.

Therefore, in order to solve the above-mentioned disadvantages, this invention
It is characterized in that the surface of the handle 10 facing the outer surface of the cooking device is formed as a heat reflecting surface 11. Specifically, an aluminum tape is formed on the surface of the handle 10 facing the front surface of the door 6. The heat reflecting surface 11 is formed by attaching evaporated silver particles by pasting or vacuum deposition. According to this, the radiant heat from the door 6 is reflected by the reflecting surface 11.
The handle portion 10a of the handle 10 can be maintained at a low temperature.

According to experiments conducted by the inventor of the present application, when the surface of the handle 10 facing the front surface of the door 6 was not formed as a heat reflecting surface 11, the temperature of the handle 10 increased by 47 degrees.
When it was formed on the heat reflecting surface 11, it greatly decreased to 18 degrees.

In this embodiment, the handle 10 is further provided with a guide portion 10b located in front of the door 6, parallel to the front surface of the door 6, and extending downward.
A cooling fan 14 is provided in a space 13 formed between the heating chamber 2 and the heating chamber 3. According to this, by driving the cooling fan 14, cold air can be caused to flow along the rear surface of the handle 10. The handle 10 can be actively cooled by this airflow, and the handle portion 10a can be maintained at an even lower temperature. Note that the air flow after cooling the handle 10 is in the space 1.
3 and is emitted to the outside through an exhaust pipe 8.

In the above embodiment, a removable saucer 15 for storing dirt such as oil flowing down from the heating chamber 3 is provided at a position opposite to the lower surface of the door 6 of the cooking device main body 2, and the dirt is collected in the saucer 15. This made it easier to clean by removing it and washing it completely.

In addition, if the cooling fan 14 of the above embodiment is operated even after cooking in the gas oven 1 is completed, and is stopped when the inside of the cooking device main body 2 reaches a certain temperature using a temperature sensor, the residual heat after use can be immediately removed. Functional parts such as control parts are always kept at a low temperature, and the outer surface of the gas oven 1 is always kept at a low temperature, thereby further improving reliability and safety. FIG. 6 shows another embodiment of the present invention, in which a handle 10 is disposed at the upper part of the front surface of the door 6 with a gap between the handles 10 and 10.
The hand grip portion 10a of 0 is composed of a recess provided on the lower surface,
The reflective surface 11 is constituted by an aluminum tape attached to the rear surface of the handle 10, and the radiant heat from the door 6 is reflected by the tape, thereby maintaining the handle portion 10a at a low temperature.

FIG. 7 shows still another embodiment of the present invention. In this case, a handle 10 is arranged on the upper surface of the door 6 with a gap, the handle part 10a of the handle 10 is the lower surface, and the reflective surface is 11 is composed of an aluminum tape attached to the upper and rear surfaces of the handle 10, and the radiant heat from the cooker body 2 is mainly reflected by the tape to maintain the handle portion 10a at a low temperature. .

(Effects of the invention) As described above, according to the invention, the surface of the handle facing the outer surface of the cooking device, for example, the surface facing the front surface of the door or the front surface of the cooking device body, is formed as a heat reflecting surface. Radiant heat from the door, the cooker body, etc. is reflected by the reflective surface, and the handle, especially the handle, can be kept at a low temperature at all times. Therefore, even when the cooker is in use, you can open and close the door by holding the handle. In addition, the handle as a whole is prevented from deteriorating due to heat, which has the effect of extending its life.
