Description

[Detailed Description of the Invention] The present invention relates to cooking equipment, and in particular to a jacket type double boiler range suitable for Chinese cuisine.

In the currently commonly practiced Chinese cooking method,
A cook 5 places a pot 4 made of steel, iron, etc. on a trivet 3 of a Chinese oven 2 having a thermal energy source 1 such as a gas burner as schematically shown in FIG. 1 of the accompanying drawings. Cooking is performed while adjusting the firepower by operating the pot 4 and operating the burner adjustment section 1A in accordance with each type of cooking such as frying, boiling, and frying. In such a single pot, the cooking temperature and its distribution are greatly influenced by the heat power, so it requires skill to maintain the cooking temperature at an appropriate level during cooking. In addition, with such a single-layer pot, the temperature of the cooking surface of the pot itself becomes too high, so you have to operate the pot by hand to prevent the food inside from burning. However, this "tilting" operation requires skill and is also hard work for the cook.

On the other hand, in the conventional Chinese oven as mentioned above,
When cooking, in order to clean the pot 4 after cooking, it is necessary to carry the pot 4 one by one to another wash area away from the Chinese microwave oven 2 and clean it there, which is also quite troublesome and labor-intensive. It was because of that. Furthermore, with conventional Chinese ovens, the heat power (input) had to be frequently adjusted manually depending on the type of cooking.

In view of the current situation, the purpose of the present invention is to develop a jacket that can completely control the cooking temperature and its distribution in the cooking pot without requiring any operation of the cooking pot, and also allows the cooking pot to be cleaned on the spot. The purpose is to provide a type double boiler range.

The jacket-type double pot range according to the present invention includes a range body and a jacket-type double-structured pot fixed on the range body, and the pot has the following features:
an inner pot that receives the material to be cooked and provides a cooking surface; an outer pot that creates a space in which a heat medium is enclosed between the inner pot; a heat transfer medium sealed in the space; and an outer pot that is arranged at the bottom of the inner pot. and a drain valve for draining water from the bottom of the inner pot through the bottom of the outer pot, and the oven main body includes a drain valve operation mechanism for controlling opening and closing of the drain valve, and A heat source for heating the heat medium from outside the outer pot is provided, and a temperature sensor for detecting the temperature of the heat medium disposed within the space and sealed therein; and control means for controlling energization of the heating source in accordance with the temperature of the heating medium detected by the heating medium.

The jacket-type double pot range according to the present invention has the following effects by having such a structure. First, a heat medium is sealed in the jacket-type double structure, and the heat medium is heated from the outside by a heat source placed outside the heat medium. Therefore, the cooking surface of the inner pot is heated by the circulation of a heat medium, and is not directly heated by a heat source. Therefore, the temperature distribution on the cooking surface of the inner pot due to heating is extremely uniform.
Moreover, the temperature does not change suddenly due to heating. Second, since the activation of the heating source is controlled according to the temperature of the heating medium detected by a temperature sensor placed in the heating medium, the temperature of the cooking surface of the inner pot can be adjusted to the desired temperature. It is easy to maintain a stable temperature at a constant temperature with very small amounts of overshoot and undershoot. Thirdly, since the heating source has a structure that is placed outside the heat medium, its structure is not limited by the influence of the heat medium, so the structure of the heat source can be freely selected. As a simple
It can be made inexpensive and has fewer failures.

As described above, according to the structure of the jacket-type double pot range of the present invention, the temperature of the cooking surface of the pot can be automatically maintained very stably despite the simple and inexpensive structure. Even ordinary people can cook food very easily without requiring any level of skill in operating the pot.

Next, the present invention will be described in more detail with regard to embodiments of the present invention based on FIGS. 2 to 8 of the accompanying drawings.

As clearly shown in FIGS. 3 and 4, the jacket type double pot 14 is formed of an outer pot 14A and an inner pot 14B, and a suitable heat is supplied to the inside of the pot from a heat medium injection port 17. A medium 26 is enclosed. This heat medium can range from 120°C to 200°C, up to 240°C depending on the purpose of cooking.
Any oil may be used as long as it can be heated to a certain degree, is non-toxic, and does not deteriorate at high temperatures; for example, it may be a polyoxyalkylene glycol synthetic oil. The outer pot 14A is provided with a heat medium outlet 27 used for exchanging the heat medium 26 with light, and a heat medium level gauge 28 for indicating the level of the heat medium 26 injected into the double structure. It is being Furthermore, as clearly shown in FIG. 3, the outer pot 14A is provided with a safety valve 29 for preventing accidents due to abnormal pressure within the double structure.

As clearly shown in FIG. 4, below the jacket type double boiler 14, there is a combustion chamber surrounded by a combustion chamber exterior plate 31 and a combustion chamber interior plate 32 with a heat insulating material 30 sandwiched therein. A main gas burner 34 as a heating source for the pot 14 is disposed in the combustion chamber 33, and a pilot burner 35 is disposed adjacent to the main gas burner 34.

A pot body fixed drain pipe 36 is provided at the bottom of the jacket type double pot 14, and a pot body intermediate drain pipe 38 is removably connected to the lower end of this drain pipe 36 via a coupling ring 37. It's summery. The drain pipe 38 is provided with a lever 38A to facilitate this operation. A range drain pipe 39 is connected to the lower end of the range drain groove 20A.

The upper part of the pot body fixed drain pipe 36 opens at the bottom of the pot 14 to form a pot body drain port 36A, and the drain valve 15 opens and closes this drain port 36A. This drain valve 15 is associated with a drain lever 16 via a connecting rod 40 and lever shafts 41 and 42. This drain valve mechanism will be explained in more detail with reference to FIGS. 5 and 6. FIG. 5 is a diagram similar to FIG. 3, but in order to particularly show the drain valve mechanism in detail, One part is broken and enlarged, and Fig. 6 shows:

Therefore, in FIGS. 2 and 3, when the drain lever 16 is moved up and down in the direction of the arrow A, the lever shaft 41 is rotated in the direction of the arrow C via the link 45, and as described above, the crank portion 41A and the slider are rotated. 43, connection rod 4
The drain valve 15 is opened and closed via the valve 0.

As clearly shown in FIG. 5, the pot 14 is equipped with a temperature signal to a control device (not shown) for detecting the temperature of the heat medium 26 and controlling the amount of heat generated from the main gas burner 34. A temperature sensor 46 is associated therewith. The main gas burner 34 is controlled by the temperature signal from the temperature sensor 46.
There are various possible ways to control this, but for example, the following control method is preferable.

The first control method, as shown in the graph in Figure 7, is to fully open the burner at the beginning of using the range, and set the pot temperature to the set temperature (in this case, 200°C).
The burner is started to be throttled down in response to a temperature signal from the temperature sensor 46 indicating that the temperature has approached 200°C, which is the set temperature, without overshoot. Next, the burner is controlled to be fully opened based on the temperature signal from the temperature sensor 46, which indicates the temperature drop due to the load when the cooking material is put into the pot. The burner is throttled down in response to a temperature signal from the temperature sensor 46 indicating that the pot temperature has approached the set temperature again. Thereafter, until cooking is completed, the pot temperature is set by closing or opening the burner in response to a temperature signal from the temperature sensor 46 that indicates a small predetermined deviation of the pot temperature from the set temperature. Maintain temperature.

The second control method, as shown in the graph in Figure 8, is to fully open the burner (on state) when you start using the range, and keep the pot temperature at the set temperature (in this case, 200°C). The burner is closed (turned off) in response to a temperature signal from the temperature sensor 46 indicating that the burner is turned on, and when the temperature of the pot drops by a predetermined value from the set temperature, the burner is turned on again. In this way, the burner is turned on in response to a temperature signal from the temperature sensor 46 indicating that the temperature has dropped by a predetermined value from the set temperature due to a temperature drop due to the load when cooking materials are put into the pot. Thereafter, until the cooking is completed, a temperature signal is sent from the temperature sensor 46 indicating that the pot temperature has reached the set temperature, and a temperature signal from the temperature sensor 4 indicating that the pot temperature has fallen by a predetermined value from the set temperature.
The kettle temperature is maintained at the set temperature by turning the burner off and on in response to the temperature signal from 6.

A temperature control device for carrying out such a control method can be easily constructed by a person skilled in the art by referring to the above description, so the specific construction thereof will not be described in detail here.

To cook in a jacket-type double pot range with such a configuration, the cook first operates the drain lever 16 to completely close the drain valve 15 and then closes the pot 1.
4.Pour oil etc. into the container. Next, the temperature controller dial 24 is operated to select a desired pot set temperature. Then, the automatic ignition piezoelectric pot 22 is activated to ignite the burner and heat the pot 14.

Since the pot 14 automatically reaches a desired set temperature, it is only necessary to put the cooking ingredients into the pot and perform a predetermined cooking operation. At this time, as mentioned above, the temperature of the pot 14 is uniform throughout the pot due to the heating medium, and moreover, it is automatically maintained at the desired set temperature, so there is no need to perform operations such as "tilting" the pot. Even if you don't do this, you won't burn the cooking ingredients,
Always able to make good food.

After cooking, take out the cooked food from the pot 14, turn on the water faucet 19 and inject cleaning water into the pot 14 to wash the pot 14, and operate the drain lever 16 to remove the waste water after use. and drain valve 15
By opening it, the waste can be drained out of the pot through the drain pipes 36 and 38. When cleaning the pot 14, water spilled onto the front top 12 of the range is drained from the drain 20A to the outside through the drain pipe 39. Also, prior to cleaning the pot 14,
If there is a liquid such as oil in the pot 14, first open the opening/closing door 25 on the front of the microwave, grasp the lever 38A and rotate the drain pipe 38 to remove the coupling ring 37 and remove it from the drain pipe 36. 38 and place a suitable container directly under the drain pipe 36, operate the drain lever 16 to open the drain valve 15, and the liquid such as oil in the pot 14 will be drained through the drain pipe 36 and into the receiving container. In this way, liquids such as oils can be reused, or flammable oils etc. can be prevented from being discharged into public drains.

In the above-mentioned embodiments, a gas burner is used as a heat source, but the present invention is not limited to this, but can be similarly applied to those using other heat sources such as an electric heater.
