In addition, the connector 158 is installed in the middle region of the wire 157 to disconnect the electrical connection.

5 is a block diagram schematically showing the electrical connection of the heating apparatus 200 according to an embodiment of the present invention. As shown in FIG. 5, the heating device 200 is configured around the controller (microcomputer) 217. The controller 217 is electrically connected to each of the members 211 and 215 of the control panel 210, and configured to receive the temperature data measured by the temperature sensor 156 and the induction heater 220. It is also configured to control the operation and is also connected to the power supply 240.

Hereinafter will be described in detail with respect to the operation of the food transport bag and the heating device equipped with a temperature sensor configured as described above.

First, the assembling process of the food transport bag 100 will be described. The heat insulation plate 140 is inserted into the first accommodating part 120, and the heat generating plate 150 is accommodated in the second accommodating part 130. Next, the connector 158 of the temperature sensor 156 is connected to allow the signal of the temperature sensor 156 to reach the first sensor terminal 160.

Then, the food transport bag 100 is placed on the upper surface of the heating device (200). In this case, the first sensor terminal 160 and the second sensor terminal 230 should be placed to be in contact with each other. Not only are the terminals 160 and 230 large enough to protrude, but also the guide bag 205 around the heating device 200 allows the carrying bag 100 to be easily positioned.

Then, the power is turned on through the key input unit 211 of the control panel 210 and the temperature is set (for example, 85 ° C.). Next, the power supply state and the operation state of the induction heater 220 are visually checked through the LED display unit 215.

The temperature is set, and the controller 217 operates the induction heater 220. The induction heating energy of the induction heater 220 heats the metal layer 152 of the heating plate 150 hot, whereby heat generated in the heating plate 150 is rapidly transferred in the vertical direction of the heating plate 150. At this time, heat transmitted downward of the heat generating plate 150 is blocked by the heat insulating plate 140. Therefore, most of the heat generated is transferred to the upper surface (based on FIGS. 2 and 4) of the heating plate 150. The food transport bag 100 itself and the internal space are heated to a predetermined temperature by the heat transferred in this way.

At this time, the temperature sensor 156 detects the temperature of the heating plate 150 at predetermined intervals and transmits the temperature to the controller 217. The controller 217 determines whether the current temperature of the heating plate 150 is above or below the set temperature or within a predetermined range based on the received sensor signal.

If the temperature of the heating plate 150 is equal to or higher than the input temperature, the controller 217 stops the heating by stopping the operation of the induction heater 220. Therefore, the temperature in the carrying bag 100 becomes low. If the temperature of the heating plate 150 is less than the input temperature, the controller 217 continues to operate the induction heater 220 to heat it.

While such a state continues, when the cooking of the pizza 110 is finished and is to be delivered, the pizza bag 110 is stored inside the carrying bag 100 and then the bag cover 105 is covered. Then, the transport bag 100 is separated from the heating device 200 and delivered to a bicycle, a motorcycle, or the like.

In order to ensure that foods with optimal temperature conditions are delivered to the customers, it is preferable to input the set temperature of the carrying bag 100 somewhat higher. This is because cooling during the delivery cannot be avoided. The value of the set temperature may be determined in consideration of weather, temperature, delivery distance, food characteristics, and the like.

Although the present invention is illustrated and described as a representative food, pizza is not necessarily limited to Korean foods (eg, Seolleongtang, stew, etc.), Chinese foods (noodles, various dishes, etc.), and others (pizza, chicken). Of course, it can also be applied to food and the like.

In addition, the present invention may be used to transport not only the foods listed above but also various industrial products, agricultural and marine products requiring warmth, without departing from the gist of the present invention.

According to the present invention, according to the food transport bag equipped with a temperature sensor and its heating apparatus, the food delivered can be maintained at an optimum temperature state by preheating the bag to a predetermined temperature before the food is delivered. Therefore, it is possible to maximize the taste of the food, thereby increasing the satisfaction of the consumer.

In addition, even when the food transport bag is preheated in advance, it is possible to prevent the safety accident such as fire due to overheating by heating only within a certain range. And, since the temperature range can be set according to the type of food, temperature, weather, delivery distance, etc., it is possible to always maintain a constant food taste.

Although the present invention has been described in connection with the above-mentioned embodiments, it is possible to make various modifications or variations without departing from the spirit and scope of the invention. Accordingly, the appended claims include such modifications and variations as fall within the spirit of the invention.
