Abstract

(57) [Summary] [Purpose] To securely hold a lamp heater with a mounting bracket even if manufacturing variations occur in the dimensions between the sealing portions at both ends of the lamp heater. Furthermore, the dedicated interior light that illuminates the cooking cabinet is abolished, and the interior light is shared by a lamp heater. [Structure] A mounting bracket having a rising portion 10 that holds the glass tube sealing portion 12 of the lamp heater 5 is formed of an elastic material, and the elasticity of the rising portion 10 urges the lamp heater in the lamp heater axial direction. Hold. Furthermore, during high-frequency heating cooking, the lamp heater 5 is also used as an interior lighting light by reducing the energization rate of the lamp heater 5 through phase control.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention uses an infrared radiant heater with a filament inside a glass tube for cooking. Concerning vessels.

0002

[Conventional technology]

Lamp heaters with a filament inside the glass tube are manufactured with a dimension between the sealed parts at both ends. Since the variation in is large and not constant, the Fixed heater mounting brackets that hold both end seals of the lamp heater The installation position of the heater may not be stable, resulting in variations in cooking performance or movement of the lamp heater. Insulation failures may occur due to a decrease in the insulation space between the heater energizing terminal and the mounting bracket. Easy to do. Furthermore, it is equipped with a dedicated interior light to illuminate the interior while cooking.

0003

[Problem that the idea aims to solve]

Even if manufacturing variations occur in the dimensions between the sealed parts at both ends of the lamp heater, the lamp heater Securely hold the data with the mounting bracket. Additionally, there is a dedicated interior light that illuminates the inside of the cooking cabinet. will be abolished and the interior light will be shared by a lamp heater.

0004

[Means to solve the problem]

The present invention consists of a heating chamber, a lamp heater installed on the upper wall of this heating chamber, and this lamp. A pair of mounting brackets that hold both ends of the lamp heater, and the upper part of the lamp heater. and a reflector that reflects infrared rays, and at least one of the above mounting brackets. It is made of an elastic material and biases the heater in a predetermined direction. Furthermore, the heating chamber and A high frequency generator that supplies microwaves to the heating chamber, and a high frequency generator installed on the upper wall of the heating chamber. control the drive of the lamp heater, this lamp heater, and the high frequency generator mentioned above. and a control circuit that controls the lamp when driving the high frequency generator. In order to reduce the energization rate of the heaters, the energization phase of the lamp heaters is controlled and the lamp heaters are driven simultaneously. Ru.

[0005]

[Effect]

At least one of the mounting brackets that hold both ends of the lamp heater is made of elastic material. When the lamp heater is installed, the mounting bracket biases the lamp heater in the axial direction. and hold it. Furthermore, during high-frequency cooking, the lamp heater contributes almost nothing to heating. Lights up the inside of the refrigerator.

【Example】

A heating cooker according to an embodiment of the present invention will be described with reference to the drawings. Figure 1 Smell 1 is a heating chamber for storing food, and 2 is a heating chamber 1 in which high frequency waves are applied via a waveguide 3. The high-frequency generator 4 for supplying is a rotary mounting table provided at the bottom of the heating chamber 1 . 5 is a lamp heater provided outside the upper wall of the heating chamber 1; It consists of a radiant heater such as a halogen heater that has a filament inside a glass tube. , the rotary mounting is carried out through a punching hole 6 provided in the heating chamber wall to block high frequency radio waves. The food placed on the table 4 is heated and cooked. 7 is fixed to the upper wall of the heating chamber and the above run A mounting bracket 8 that holds both ends of the lamp heater covers the lamp heater 5 and attaches it to the lamp heater. This is a reflecting plate that reflects infrared rays radiated by the heater 5 into the heating chamber 1.

[0007] Figure 2 shows an example of the shape of the lamp heater mounting bracket 7, and shows how it can be fixed to the heating chamber wall. part 9, and an inverted L that extends to both sides of the fixed part 9 and stands up at an obtuse angle with respect to the fixed part 9. A letter-shaped rising portion 10 and a rising portion 10 connected to this rising portion 10. A U-shaped portion 11 is formed to fit with the lamp heater 5, which hangs down at an acute angle to the lamp heater. Ru. This mounting bracket 7 is fixed to the heating chamber wall 1a as shown by the broken line 10a in FIG. After that, the rising portion 10 is elastically deformed as shown by the solid line, and the lamp heater is The stepped portion of the glass tube sealing portion 12 that accommodates the filament No. 5 is fitted into the U-shaped portion 11. and hold the lamp heater 5 while urging it in the heater axial direction.

[0008] FIG. 4 shows the electric circuit of the heating cooker, where 13 is the commercial power supply and 14 is the heating chamber 1. A door switch that turns on and off in conjunction with the opening and closing of the door, 15 is the door switch mentioned above. A monitor switch that shorts the commercial power supply and melts the fuse 16 when the fuse 14 contacts are welded. It is 17 is a control circuit that controls the heating source of the cooking device, and the above-mentioned high frequency generation Controls the relay contact 18 that controls the drive of the device 2 and the energization of the lamp heater 5. The triac 19 is controlled.

[0009] When cooking with a heater, for example, a 620W lamp heater 5 is connected to a commercial power source. By turning on the triac at a energization rate of 50% or more with respect to the source, the desired red color can be obtained. Provides external radiant heating and interior lighting.

0010 On the other hand, during high-frequency heating cooking, the relay contact 18 is turned on and the high-frequency generator In addition to driving the lamp heater 2, for example, a 620W lamp heater 5 is installed as shown in FIG. The triac 19 By controlling and driving the turning on phase, high-frequency heating adjustment using radiant infrared Provide lighting inside the refrigerator to minimize the impact on the process.

[0011]

[Effect of the idea]

Since the lamp heater was fixed using the elasticity of the mounting bracket, the lamp heater Even if there are variations in the dimensions between the sealed ends, the lamp heater can be securely held and removed. The attachment position becomes stable. Furthermore, when cooking with high frequency heating, a small amount of electricity is applied to the lamp heater. By driving the lamp at a high rate, the influence of radiant infrared rays on cooking can be reduced. The heater can be shared with the interior light. Furthermore, even if it is driven at the same time as a high frequency generator, the power supply capacity is Never exceed the amount.
