Description

[Detailed description of the invention] This invention relates to a cooking device that microwaves food immersed in cooking oil, and changes the hanging position on the arm of the cooking basket depending on the shape and thickness of the food. , the purpose is to efficiently supply microwave energy to foods to be cooked.

In general, a cooking device called a microwave fryer immerses the food to be cooked in cooking oil heated to a constant temperature by a heat source such as a heater or burner.
The food to be cooked is fried by supplying microwave energy to the food.
By the way, in the above-mentioned case, the food to be cooked is stored in a cooking basket, and the food is immersed together with the cooking basket in cooking oil for cooking.
Since the distance from the oil level to the surface of the object to be cooked varies depending on the thickness, there is a problem that microwave energy cannot be efficiently supplied to various objects to be cooked. For example, when cooking something with a small thickness,
Since it is deeply immersed in the edible oil, the distance from the oil surface becomes large, and as a result, the microwave energy irradiated by the microwave heating means is absorbed into the oil and is greatly attenuated.

Therefore, conventionally, various cooking baskets are prepared depending on the type of food to be cooked, that is, the shape and thickness, and cooking is performed using the cooking basket depending on the food to be cooked. However, in this case, since many types of cooking baskets are required, the number of parts increases, and the cooking baskets must be replaced depending on the food to be cooked, resulting in poor workability during cooking.

This idea was made with the above points in mind, and includes cooking oil that is stored in an oil tank in the cooking chamber and heated to a constant temperature by a heat source, and a cooking oil that is integrally supported on a rotating shaft above the oil tank for cooking. an arm that is rotated downward when the arm is rotated; a plurality of hooks arranged in the longitudinal direction of the arm at the tip of the arm; and a cooking device that is equipped with a cooking basket that immerses the food to be cooked in the cooking oil by rotation of the arm during cooking, and a microwave heating means that heats the food that is immersed in the oil. This is what we provide.

Therefore, according to the cooking device of this invention, a plurality of hooks from which the cooking basket is suspended are formed at the tip of the rotatable arm, and these hooks are arranged in the longitudinal direction of the arm, so that the cooking basket can be hung from the hook. The height of the cooking basket in the oil tank can be adjusted only by changing the hanging position on the arm, and therefore the cooking basket can be suspended from a predetermined hook depending on the shape and thickness of the food to be cooked. This makes it possible to keep the immersion state of various items to be cooked almost constant and efficiently supply microwave energy, eliminating the need to prepare a variety of cooking baskets as in the past, and improving workability. It is.

Next, this invention will be explained in detail with reference to drawings showing one embodiment thereof.

In the drawings, 1 is the main body of the cooking device, 2 is a cooking chamber formed in the main body 1 with an opening at the front, and 3 is rotatably supported on the front of the main body 1 and has a front opening of the cooking chamber 2. Door that can be opened and closed freely, 4

Reference numeral 10 denotes a sheathed heater that heats the cooking oil in the oil tank 9. When the operation switch 8 is turned on, the sheathed heater 10 is turned on and off at a set temperature, and the cooking oil is always heated to a constant temperature. 11 is a magnetron serving as a microwave heating means, 12 is a waveguide, and 13 is a power supply port, and the microwave output from the magnetron 11 passes through the waveguide 12 and is irradiated into the cooking chamber 2 from the power supply port 13. Ru.

Reference numeral 14 denotes a rotation shaft provided laterally at the rear of the center of the cooking chamber 2 and rotatably supported by a bearing 15 on the side wall of the cooking chamber 2. Reference numeral 16 denotes a rotation shaft whose base is integrally supported by the rotation shaft 14. These are arms that are rotated up and down by a moving shaft 14, and two arms 16 are located on the left and right sides of the cooking chamber 2. 17a, 17b, 17c are three hooks formed at the tip of each arm 16 and arranged in the longitudinal direction of the arm 16; 18 is an arbitrary hook 17a, 17b, 17c of each arm 16; The cooking basket 18 is a suspended cooking basket, and the food to be cooked is stored in the cooking basket 18.

19 is a rotation shaft 1 led out from the side wall of the cooking chamber 2
A rotating lever 20 integrally connected to the end of the apparatus body 1 is a torque motor disposed at the rear of the main body 1, and is always energized, and is de-energized only during cooking. Reference numeral 21 denotes a drive lever connected to the shaft of the torque motor 20, and the tip of the lever 21 and the tip of the rotating lever 19 are connected by a spring 22.
The rotation of the drive lever 21 by the torque motor 20 causes the rotation lever 19 to rotate, and further rotates the rotation shaft 1.
4, the arm 16 is rotated. 23 and 24 are an upper stopper and a lower stopper of the rotating lever 19.

Next, the operation of the above embodiment will be explained.

First, prior to cooking, the operation switch 8 of the operation section 4 is turned on to start driving the sheathed heater 10 to heat the edible oil in the oil tank 9. This oil tank 9 is equipped with a temperature sensor for detecting the temperature of cooking oil, and when the cooking oil is heated to a set temperature, the sheathed heater 10 is turned off, and when the oil temperature falls below the set temperature, it is turned on again. , which maintains the cooking oil at the set temperature.

Also, since the torque motor 20 is normally in an energized state, a downward rotational force acts on the drive lever 21, and this is transmitted to the rotation lever 19 via the spring 22, as indicated by the dashed line in FIG. As shown, the rotating lever 19 rotates downward and the lower stopper 24
It stops at the position , and this state is maintained by energizing the torque motor 20 . At this time, the arm 16 is rotated upward as shown by the dashed line in the figure and stopped.

Then, the door 3 is opened and the cooking basket 18 containing the food to be cooked is placed in the predetermined hooks 17a, 1 of both arms 16.
7b, 17c, that is, hooks 17a, 17b, 17c selected according to the thickness and shape of the food to be cooked.
hang it. For example, if the thickness and shape of the object to be cooked is large, it may be hung from the hook 17a on the tip side.
Moreover, if it is small, it is hung from the hook 17c on the base side. Next, a predetermined menu select key is selected from the cooking selection section 6 of the operation section 4 and pressed to set the time for immersing the food to be cooked in the oil and the time for heating by microwave.

After that, when the door 3 is closed and the start key 7 is pressed, the power supply to the torque motor 20 is canceled, so the arm 16 is rotated downward by the weight of the cooking basket 18, and the rotation lever is moved from the position indicated by the one-dot chain line. 19
moves to the position indicated by the solid line where it abuts the upper stopper 23, and is held at this position. Therefore, the cooking basket 18 suspended from the arm 16 rotates around the rotation axis 1.
The food to be cooked in the cooking basket 18 is immersed in the cooking oil.

The food to be cooked is immersed in the cooking oil for a time set by the menu select key, fried by the temperature of the cooking oil heated by the sheathed heater 10, and heated by the microwave output from the magnetron 11. and predetermined cooking is performed.

Next, when the cooking time set by the menu select key ends, the power supply to the torque motor 20 is restarted, and the rotational force generated in the drive lever 21 is applied to the spring 22, the rotation lever 19, and the rotation shaft 14.
The oil is transmitted to the arm 16 through the oil, and returns to the state shown by the one-dot chain line in FIG. 2, and as the arm 16 rotates upward, the cooking basket 18 is taken out from the oil. After that, the door 3 is opened and the cooking basket 18 is taken out.

Therefore, according to the embodiment, three hooks 17a, 17b, and 7c can be arranged and formed in the longitudinal direction of the arm 16 at the tip of the arm 16, which rotates up and down within a certain angle. , the cooking basket 18 containing the food to be cooked is placed on an arbitrary hook 17.
a, 17b, and 17c, the height of the cooking basket 18 during cooking, that is, the height from the oil level to the bottom of the cooking basket 18, can be set variously. By selecting the hooks 17a, 17b, 17c according to the type, the height of the cooking basket 18 can be easily changed and the food to be cooked can be efficiently heated with microwaves.
There is no need to prepare various cooking baskets depending on the food to be cooked, and the conventional drawbacks can be overcome.

In addition, by being able to vary the height of the cooking basket 18, it becomes possible to immerse the food to be cooked shallowly in cooking oil and efficiently supply microwave energy, even for relatively thick food. It allows for efficient cooking in a short time.
