Abstract

PURPOSE:In the preparation of smoked food, the temperature of the smoke generated by heating wood pieces is controlled to a prescribed value by means of a cooler to give various kinds of smoked products. CONSTITUTION:The cooker is composed of a heater 3 for wood pieces 4, a duct 7 for leading the smoke generated from wood pieces 4, a cooler (e.g., blower 13) for cooling the duct 7, a temperature sensor (e.g., thermistor 18) set in the oven 10 to detect the temperature of the smoke, and the control circuit for controlling the cooler 13 responding to the signals from the sensor. The temperature of the smoke is detected by the thermistor 18, the signals are amplified by the transistor 20 to switch the contact 22 through relay 21 and control the blower motor 23.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cooking device for producing smoked foods.

2. Description of the Related Art A conventional cooking device of this type includes a main body 26 and a lid 2 of a barbecue grill mainly used outdoors, as shown in FIG.
7 and a ventilation opening 28, and when producing smoked food, a method was adopted in which a piece of wood was heated at the bottom of the main body 26, and the food was smoked by covering it with a lid 27.

Problems to be Solved by the Invention Originally, in the production of smoked foods, there are two methods: cold smoking, which saves relatively low-temperature smoke, and hot smoking, which saves high-temperature smoke. In addition, among these methods, the temperature of the smoke at which smoke is reduced varies depending on the type of food.

However, with the above configuration, the temperature of the smoke can only be adjusted using the ventilation port 28, so it has a decisive drawback in that only a few types of smoking can be done.

The present invention aims to solve such conventional problems, and aims to enable various types of smoking by freely setting the smoke temperature.

Means for Solving the Problems In order to solve the above problems, the cooking device of the present invention includes a heating device for heating pieces of wood, a smoke conduit for guiding smoke generated from the heated pieces of wood, and a cooling for the smoke conduit. The cooling device includes a cooling device, a temperature sensor that detects the temperature of the smoke, and a control circuit that controls the cooling device in accordance with a signal from the temperature sensor.

According to the above-described structure, when a piece of wood is heated by a heating device and the resulting smoke is guided through a smoke conduit, the temperature of the smoke is maintained at a set value by a cooling device controlled by a signal from a temperature sensor. This makes it possible to produce smoked food at the desired temperature.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

In Fig. 1, reference numeral 1 denotes the main body of the cooking device, a box body 5 in which a heat insulating material 2 is placed at the bottom, an electric heater 3 as a heating device, and a piece of wood 4 is placed.
is provided. 6 is a smoke inlet, and a meandering smoke pipe 7
Furnace 10 with food 9 installed at smoke outlet 8 via
It leads to.

11 is a smoke escape port. 12 is the air intake port and blower 1
3 is blown into the duct 15 from the air outlet 14 and discharged from the outlet 16. Note that 17.17 is a heat shield plate.

FIG. 2 shows a control circuit for measuring the temperature of the blower 13, including a thermistor 18, a variable resistor 19, and a transistor 20.
The blower motor 23 is controlled by opening and closing the contacts 22 via the relay 21. 24 is a DC power supply, and 25 is an AC power supply.

To produce smoked food in the above configuration, the food 9 is placed in the furnace 10 and the wood pieces 4 are placed in the box 5.

When the wood chips 4 are heated by the electric heater 3, the generated smoke enters the furnace 10 through the smoke inlet 6, the smoke conduit 7, and the smoke outlet 8, smokes the food 9, and then exits from the smoke escape port 11. Outlet 1
6 and is discharged to the outside of the main body 1. At this time, blower 1
3 is driven, the smoke in the smoke conduit 7 is cooled and the low temperature smoke is added to the food 9. Further, a thermistor 18 as a temperature sensor installed in the furnace 10 detects the temperature of the smoke, and the signal is amplified by a transistor 20 and opens/closes a contact 22 via a relay 21. As a result, blower 1
3 turns on and off depending on the temperature of the smoke (it turns on if it's higher than the set temperature, and turns off if it's lower than the set temperature), and the temperature of the smoke is kept constant, making it possible to smoke at various temperatures.

Further, the set temperature of the smoke is set by a variable resistor 9.

Although the blower 13 was controlled on and off in this embodiment, it is of course possible to use proportional control to further improve the accuracy, and to control its capacity with a cooling device such as a refrigerator, it is possible to control the smoke over a wider range. Temperature control becomes possible.

Effects of the Invention As described above, the cooking device of the present invention provides the following effects.

Equipped with a control device that detects the temperature of the smoke in the furnace and controls the cooling device, the food is always smoked at a constant temperature in the furnace, making it possible to smoke various types of smoked food. It becomes possible to manufacture
