Description

ELECTRIC FURNACE COOKING SYSTEM

The present invention relates to an electric heater power control method of the electric heating cooker system and an electric heating cooker system using the method, more specifically, a meal of a large number of people at a time, such as school cafeteria, government office restaurant, company cafeteria, hotel restaurant The present invention relates to a method for controlling electric heater power of a cooking system, and a heating system using the same method, which can continuously cater for meals in a high-quality state at a restaurant that provides the food.

Group meals, such as school cafeteria, government office cafeteria, company cafeteria, and hotel cafeteria, cannot cook the required amount of rice even when using a large cooker. Cook the rice over.

A gas cooker or a heat cooker for a single meal is provided with a burner or a heater inside the cooker, and is cooked by placing a rice cooker containing rice to be cooked on the burner or the heater. The gas cooker and electric heat cooker for a single meal are equipped with a temperature sensor in the bottom of a rice cooker, and when a temperature rises more than a predetermined temperature, it is used for shutting off a gas or shutting off a power supply. The temperature sensor is usually installed to contact the bottom bottom of the rice cooker. When the temperature of the temperature sensor reaches a certain temperature, the controller of the group cooking gas cooker or the electric heat cooker determines that the cooking of the rice is at a stage of steaming, and once the gas or power is cut off, the controller switches to the steaming mode. It is.

The burner of the gas cooker for a group meal or the heater and the rice cooker of the electrothermal cooker are surrounded by a heat insulating wall and the like, and are configured to prevent the heat generated from the burner or the heater from leaking to the outside. Therefore, the conventional cooking control method of cutting off the gas of the cooker or cutting off the power on the basis of the ambient temperature of the rice cooker or the temperature of the bottom of the rice cooker in the outer wall of the cooker is as follows. It causes the same problem.

First, the conventional rice cooker has a problem that it is difficult to cook rice continuously without time loss in the middle by using the same rice cooker.

This is due to the residual heat inside the cooker which occurs at every cooking. That is, in the case of the second cooking after the first cooking, the heat generated in the first cooking process remains around the burner or the heater, and in the second cooking, the cooking control is performed based on the temperature around the burner or the heater where the residual heat remains. In the second cooking, the secondary cooking is not performed properly because the temperature value read from the temperature sensor reaches the cutoff temperature of the gas or the power source even with a slight heating. That does not mean you can remove the insulation walls. If the insulation wall is removed in a large cooker, the heat loss is so severe that it is difficult to uniform the entire mass at once.

Therefore, at present, the waiters wait until the inside of the cooker cools down, and then cooks new dishes. However, cooling the inside of the cooker at every cooking time lengthens cooking time and wastes calories.

In addition, there is a problem that the rice is not cooked uniformly as a whole when the cooking control based on the temperature of any point of the lower part of the cooker inside the cooker. This is because the temperature at one point is difficult to faithfully reflect the temperature at the other point inside the cooker.

The present invention devised to solve the problems of the above-mentioned large-capacity rice cooker uses an electric heater power control method of the electric heating cooker system which can cook rice continuously without intermittent time delay even if cooked several times using the same rice cooker. To provide a cooking system in the heat transfer.

Another object of the present invention is an electric heater power control method of the electric heating power cooking system and cooking method using the method that can cook a large amount of rice uniformly by heat storage and heat reflection without increasing the pressure of the steam cooker steam at high pressure. To provide a system.

Still another object of the present invention is a method of controlling electric heater power of a cooking system in which an electric rice cooker can be cooked in a uniform state as a whole by cooking rice based on a temperature that can be summed up to indicate the overall cooking state of the cooker. And providing a cooking system using heat transfer using the method.

Electric heater power control method of the electric heating cooker system according to the present invention to achieve the above object In providing an electric heater inside the electric furnace surrounded by the furnace wall, cooker by cooking inside the electric heating furnace, A steam discharge pipe for guiding the discharge of water vapor from the inside to the outside with heat transfer is formed by extending the protrusion to the outside of the furnace wall with the heat transfer, and the temperature sensor is provided in the inner end pipe of the steam discharge pipe, and the external heat vapor measured by the temperature sensor It is characterized by performing a power input cut-off for the electric heater based on the temperature.

Electrothermal furnace cooking system according to the present invention to achieve the above object is an electric heater provided in the closed space by the furnace wall (노) and the door (爐門); A steam discharge pipe extending through the furnace wall to the outside of the furnace wall; A temperature sensor provided in an inner tube of the distal end of the steam discharge pipe to measure an external steam temperature by an electric heat transfer; And a control unit which cuts off the power of the electric heater when the temperature measured by the temperature sensor reaches a preset temperature.

The lower portion of the electric heater is preferably provided with a steel heat storage plate plated by mixing aluminum and zinc.

According to the present invention having the above-described configuration, a large amount of rice can be continuously cooked several times without delay using the same cooker, and at each cooking time, it is not necessary to cool the inside of the cooker, but rather the residual heat can be used. There is an effect that can reduce the time, save cooking calories and costs. In addition, the temperature of the steam discharged to the outside by the heat transfer does not indicate a partial cooking state inside the cooker, but represents the overall heating state inside the cooker. There is an effect that can be cooked uniformly as a whole.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the electric heater power control method of the electric heating cooker system according to the present invention and the electric heating cooker system using the method.

1 is a block diagram of a heating stove cooking system according to the present invention, Figure 2 is a flow chart of the electric heater power control method of the heating stove cooking system according to the present invention, Figure 3 is used in the heating stove cooking system according to the present invention Is a perspective view of a cooker.

Referring to Figure 1, the heat transfer furnace according to the present invention is surrounded by a lower furnace wall (1), a side furnace wall (3) and the upper furnace wall (5), the one side of the furnace door (爐門) to the front It is arranged to open. The electric heater 13 is disposed inside the heat transfer furnace while the insulation of the furnace walls 1, 3, and 5 is maintained adjacent to the floor, and the rice cooker 21 is slightly disposed on the inner surface of the heat furnace side furnace wall 3. The hanger rail 9 which can support the space | interval of at least is provided. A hanger rail 9 capable of supporting one side of the rice cooker 21 is also provided on the inner surface of the furnace door 7. At the time of cooking, the rice cooker 21, in which rice and rice are accommodated, is inserted while the cover is closed.

Referring to FIG. 3, the cooker 21 has a substantially rectangular tubular shape, and a flange 23 extending outward is formed at an upper edge thereof, such that the flange 23 can be hung on the hanger rail 9. It can be seen that.

The user sets the operation of the electric heater 13 through the control unit 19, and the control unit 19 performs cooking by controlling the power on and off of the electric heater 13 according to the setting.

A characteristic of the present invention is to form a steam discharge pipe (15) extending through the furnace wall (3) to the outside of the furnace wall (3), the temperature sensor 17 is provided in the inner end pipe of the steam discharge pipe (15) After the external steam temperature is measured by heat transfer, when the temperature measured by the temperature sensor 17 reaches a preset temperature based on this temperature, the electric power of the electric heater is cut off. The steam discharge pipe 15 is formed to protrude to the outside from the furnace wall (3), the inner end of the pipe is exposed to the outside air when there is no discharge of steam, so when cooking is finished immediately cool, but cooking starts and steam passes In this case, the inflow of outside air is blocked by the discharge pressure of the steam, and the discharge steam temperature is faithfully reflected. Therefore, even in the case of continuous cooking, the detected temperature value of the temperature sensor does not rapidly increase in the early stage of cooking due to the residual heat inside the furnace.

Another feature of the present invention is that the lower portion of the electric heater 13 is provided with a heat storage plate 11 of steel plated by mixing aluminum and zinc. Since the heat capacity of the steel heat storage plate 11 reaches 770 kcal / ° C. 3, it is thousands of times larger than the heat capacity of air wrapped around the rice cooker (0.29 kcal / ° C. 3 m 3). Therefore, the steel heat storage plate 11 focuses and radiates the amount of heat transferred downward from the electric heater 13, and supplies a large amount of heat to the rice cooker. In this way, while cooking steam into the steam discharge pipe 15 during cooking, mass cooking is possible. In particular, when aluminum and zinc are mixed and plated on the surface of steel, the corrosion resistance and durability are improved, and heat reflection is increased, so that the steel heat storage plate 11 not only radiates due to heat accumulation but also heat reflection. The heat supply to the rice cooker is smoothed.

2 shows a control method of the cooking system with such heat transfer.

When the power of the cooking system is turned on by the heat transfer, the controller 19 sets the discharge steam set temperature and the moxibustion set time to a default value of the control program (the initial set value at the program or the user change value at the previous cooking time). (100), power is supplied to the electric heater (13). At this time, by the user's interrupt, it is possible to change the initial moxibustion set time or discharge steam set temperature (power cut-off temperature for the electric heater) (101, 102). After the electric power is input to the electric heater 13, the control unit 19 receives the steam temperature discharged to the outside by the heat transfer from the temperature sensor 17 (104), the discharge steam temperature is equal to or exceeds the set temperature. It is determined whether or not (105). If the discharge steam temperature is higher than the set temperature, the control unit 19 cuts off the power of the electric heater 106, and performs moxibustion according to a predetermined program. In the process of inducing moxibustion, the electric heater 13 is intermittently turned on at regular intervals during the moxibustion setting time.

When the moxibustion setting time ends, the control unit 19 displays the cooking completion indication to the user through an alarm or a lamp.

Figure 4a is a perspective view from the front showing the heat transfer furnace of the heat transfer cooking system according to the present invention in three stages, Figure 4b is a partial cutaway perspective view showing a part of the control system and the top heat transfer cooking system in Figure 4a 4C is a perspective view showing the cooking system in the rear of the heat transfer cooking apparatus shown in FIG. 4A, FIG. 5 is a perspective view showing a state in which a cooker is opened to install the cooker inside the heat transfer furnace, and FIG. The perspective view which shows the state mounted in the furnace inside is shown, respectively.

As shown in FIG. 4A, when the heat transfer furnace is configured in multiple stages, the control of all heat transfer furnaces is performed by the controller 19 disposed at the top thereof. To this end, the front of the control unit 19 is provided with a power switch, each stage (upper, middle, lower) selection switch, electric heater power input time reservation setting switch and time display of each stage, so that each stage can be individually controlled Prepare cooking rice type (grain, general) selection switch, gap setting duration switch and time display, cooking display lamp, steaming display lamp, cooking finish display lamp for each stage electric heating furnace.

As shown in FIG. 4B, the side furnace wall 3 is formed of a stainless steel plate to form a hollow wall inside, and the inside of the wall is preferably filled with a heat insulator, in which case the ripple is particularly ripple. It is preferable to use a reflextherm (trade name of a reflective insulating material manufactured by Reflectflex, France). Reflector is a reflective insulation material that has an aluminum layer with heat reflection on both surfaces of glass fiber with very low thermal conductivity. Suitable as filler inside furnace walls. In particular, when the reflector is filled with an air layer in the middle, the insulation effect is further increased. Not only the side furnace wall 3, but also the upper furnace wall 5 and the lower furnace wall 1 are preferably molded with the same structure and material as above.

In addition, as shown in Figure 4b, it is preferable to further attach a heat storage plate 29 of the same material as the heat storage plate 11 provided on the bottom to the inner surface of the side furnace wall (3). The hanger rail 9 is provided at a constant height on all three surfaces of the side furnace wall 3 so that the flange 23 of the rice cooker 21 is stably hung.

Electric heating cooker system according to the present invention will produce a large amount of steam in a large rice cooker at a time generates a large amount of steam. Therefore, as illustrated in FIG. 4C, not only the steam discharge pipe 15 having the temperature sensor 17 provided therein, but also the auxiliary steam discharge pipe 27 is further provided in the heat transfer path at each stage.

As shown in Figure 4b and 5, the furnace door 3 of the electric heating cooking system according to the present invention is preferably coupled to the hinge (5) in front of the main body of the electric heating to open and close forward. This is because it is easy to stack the heat transfer furnace in multiple stages, and it is easy to put a large rice cooker into the heat transfer furnace or to withdraw the heat transfer furnace from the inside.

5 and 6, in order to cook rice, the user opens the door 7 and pushes the rice cooker 21 containing the rice to be cooked so that its wings 23 hang on the hanger rail provided on the furnace wall. After closing, close the door (7). Next, after the necessary setting in the control unit 19 will be cooked.
