[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electric cooking appliance using an infrared lamp that emits infrared rays including far infrared rays.
[0002]
[Prior art]
An external view of a general electric cooking appliance is shown in FIG. 100 is a power switch, 101a and 10b are lamps, 102 is a grill, 103 is a net shelf.
[0003]
This electric cooking appliance is an open type product in which lamps 101a and 101b are arranged one above the other. In general, many cooking appliances of this type are employed.
[0004]
[Problems to be solved by the invention]
Since it is an open type, the rising of the initial ambient temperature of the cooking device itself is only the heat generated from the lamps 101a and 101b, so it takes a warm-up time for cooking the food including the grill. Also, the time to bake the ingredients will be delayed.
[0005]
Accordingly, an object of the present invention is to provide a sealed electric cooking apparatus that can shorten the warm-up time by raising the temperature of the cooking space in the outer shell as fast as possible, thereby shortening the baking time of ingredients. It is in.
[0006]

The electric cooking device according to claim 1, wherein the outer shell portion, an infrared lamp that radiates infrared rays including far infrared rays disposed in the outer shell portion, and a reflection that is disposed above the infrared lamp and has a heat dissipation hole. plate and a translucent partition that partitions the infrared lamp space with said shell disposed has been cooked space in the unit and of said infrared lamp and the reflector, the inside the outer shell portion of the lighting start mode of the infrared lamps A temperature increase acceleration means for increasing the temperature of the cooking space to increase the temperature, and the temperature increase acceleration means is an air duct that sends heated air that has been heated by the infrared lamp and passed through the heat radiation hole to the cooking space.
[0007]
According to the electric cooking appliance of claim 1, the air heated by the infrared lamp by the air duct of the temperature raising acceleration means is sent to the cooking space, and the food can be rapidly heated at the start of lighting by the air heat. The rise time can be made faster. Therefore, the heat of the infrared lamp can be effectively used for the initial heating in the cabinet.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
A first embodiment of the present invention will be described with reference to FIGS. That is, in FIGS. 1 and 2, the outer shell portion 1 constituting the main body is made of a steel plate such as stainless steel, and a door 3 for feeding and unloading food, a power switch 4 and the like are provided thereon. A plurality of infrared lamps 6 for emitting infrared rays including far-infrared rays are arranged horizontally in a lower part of the reflector 5 for effectively reflecting the lamp irradiation. A cooking space 9 for baking an object to be cooked is between the infrared lamp 6 and a grill net 7 below the infrared lamp 6, and a saucer 8 for the broth is disposed below the grill net 7.
[0019]
The outer shell 1 is hermetically sealed, and the cooking space 9 and the lamp space 10 are separated by a translucent partition 18. Then, the cooking object is placed on the grill 7 and the infrared lamp 6 is turned on to heat the cooking object. At this time, several heat radiation holes are arranged on the upper surface of the reflection plate 5 used in combination with the lamp 6, and the heat radiation from the lamp 6 is released upward.
[0020]
The temperature raising acceleration means is for rapidly raising the lamp temperature by turning on the infrared lamp 6 at a high frequency and applying an inrush current at the time of rising. FIG. 3 shows the characteristics of irradiance with respect to time, where a represents a general rise and b represents a rapid rise characteristic.
[0021]
Thereby, the inside temperature can be raised rapidly.
[0022]
A second embodiment of the present invention is shown in FIGS. That is, the heat radiating hole 13 is formed in the reflector 6 and the air duct 12 is provided between the cooking space 9 and the upper portion of the lamp space 10. Lamp heat (arrow) released from the gap between the heat radiating hole 13 and the reflecting plate 6 is sent into the cooking space 9 through the blower duct 12 by using a convection action by convection heat or by providing a blower means in the middle. Thereby, the temperature in the cooking space 9 is maintained at a constant temperature.
[0023]
By effectively drawing the heat generated by the infrared lamp 6 into the cooking space 9, the temperature in the cabinet can be quickly raised.
[0024]
A third embodiment of the present invention will be described with reference to FIG. That is, the use lamp 6 is provided with a spare lamp 6a with a reflector, and the spare lamp 6a is also turned on when the lamp is turned on, thereby increasing the number of lamps to increase the radiant energy.
[0025]
By changing the total amount of radiant energy in the lamp 6 determined by the input control, the internal temperature can be raised quickly. Further, by adding a function of changing the amount of energy applied to the food material, the baking of the food material can be adjusted.
[0026]
A fourth embodiment of the present invention will be described with reference to FIG. That is, this is a case where the voltage of the same infrared lamp 6 to be used is controlled by electrical control. For example, the voltage applied to the infrared lamp 6 by changing the connection method of the six infrared lamps 6 to the three-phase power supply 11 is changed. Change to control the output. 7A, the plurality of infrared lamps 6 and the power source 11 are Δ-connected, the switch unit 15 is turned on, and the Y-connection as shown in FIG. 7B is switched. Thereby, the voltage applied to the infrared lamp 6 is changed to 100V or 115V. Therefore, Δ connection is used for low output, and Y connection is used for high output. At this time, the lamp radiant energy is increased by the applied 115 V voltage, and therefore the internal temperature can be raised quickly.
[0027]
FIG. 7B shows a case where the power source 11 is Y-connected.
[0028]
A fifth embodiment of the present invention will be described with reference to FIG. That is, a heat source for quickly raising the inside temperature is provided separately from the infrared lamp 6 for cooking food. In the embodiment, the heater 17 is disposed below the grill 7, the heater 17 and the cooking space 9 on the upper side of the grill 7 are connected by the air duct 19, and the heat of the heater 17 is convectively or via the air blowing means. Send to cooking space 9.
[0029]
Thereby, the temperature of the cooking space 9 can be raised quickly.
[0030]
A sixth embodiment of the present invention will be described with reference to FIG. That is, a part of the infrared lamp 6 for cooking the food is used as a preheating combined lamp 6b to increase the internal temperature in advance during cooking, and the internal temperature is quickly raised during cooking.
[0031]
【The invention's effect】
According to the electric cooking appliance of claim 1, the air heated by the infrared lamp by the blower duct of the temperature raising acceleration means is sent to the cooking space, and the food can be rapidly heated at the start of lighting by the air heat. The rise time can be made faster. Therefore, the heat of the infrared lamp can be effectively used for the initial heating in the cabinet.
