Third Embodiment
The heating cooker of 3rd Embodiment of this invention is carrying out the structure same as the heating cooker of 1st Embodiment except for packing, and uses FIG. 1-FIG.

  The heating cooker of the third embodiment differs from the heating cooker of the first embodiment in that an opening is provided in one side wall of the packing attachment portion 150.

  In this case, the air passage 151 into which the cooling air of the packing attachment portion 150 flows is open toward the upstream side of the cooling air.

Fifth Embodiment
The heating cooker of 5th Embodiment of this invention is carrying out the structure same as the heating cooker of 1st Embodiment except for a communication function, and uses FIG.

  In recent years, in a heating cooker, it is known to use infrared communication to connect to a portable terminal such as a smartphone and to transmit data for heating and cooking from the portable terminal to the heating cooker.

  However, in the case of transmitting the data for cooking by infrared communication, the data is transmitted for each menu, and it may take too long to transmit a large amount of data.

  So, in the cooking-by-heating machine of this 5th embodiment, the method to transmit and receive efficiently the data for cooking is explained.

  The heating cooker includes a communication unit (not shown), and the communication unit can be connected to a portable terminal or a server via a network, for example, by a wireless LAN (local area network). . The communication unit transmits and receives information to and from, for example, a portable terminal or a server device.

  A large number of data for heating and cooking are registered and managed in the server device, and for example, a cooking menu name, a cooking number, and the like are associated with each data for heating and cooking.

  Here, when the user uses a portable terminal, selects a plurality of data for cooking that is registered in the server device, and transmits the data to the cooking device, the data for cooking is compared and common. If there is a part, do not send duplicate data. By doing so, the data for cooking can be efficiently transmitted and received, and the time for transmitting and receiving the data can be shortened.

  Regarding the data for cooking, for example, the data is divided according to the heating step (microwave, steam, heating method such as a heater, etc.), and the data of a typical heating pattern often used is prepared in advance As for data of typical heating patterns that are stored in the main unit and often used, data stored in the heating cooker main body is used by transmitting abbreviated data instead of transmitting and receiving all data. May be

  Moreover, the method to transmit the data for heating and cooking registered with the server apparatus to a heating cooker on the predetermined date and time is demonstrated.

  When the user inputs, for example, the cooking number and the cooking date and time from the portable terminal and transmits the same to the server device, the server device heats and cooks the cooking date and time or slightly before the input cooking date and time. Data is sent. By doing so, even if a plurality of data for heating and cooking are selected, it is not necessary to transmit and receive a plurality of data at a time because data is transmitted and received on each designated cooking date and time, and data are transmitted and received efficiently. Can reduce the time to send and receive data at one time.

  Although the said 1st-5th embodiment demonstrated the heating cooker provided with the infrared sensor unit 100, a sensor unit is not restricted to this, This invention is applied to a heating cooker provided with sensor units, such as an image sensor. You may

  In the first to fifth embodiments, the air passage 151 into which the cooling air flows is provided in the packing attachment portion 150. However, the air passage into which the cooling air flows may be provided in the packing. It is also possible to provide an air passage into which the cooling air flows.

  In the heating cooker of the present invention, healthy cooking can be performed by using superheated steam or saturated steam in an oven range or the like. For example, in the heating cooker of the present invention, superheated steam or saturated steam having a temperature of 100 ° C. or higher is supplied to the food surface, and the superheated steam or saturated steam adhering to the food surface condenses to give a large amount of latent heat of condensation to the food. So you can efficiently transfer the heat to the food. In addition, when the condensed water adheres to the food surface and the salt and oil drop together with the condensed water, the salt and oil in the food can be reduced. Further, the inside of the heating chamber is filled with the superheated steam or the saturated steam to be in a low oxygen state, which makes it possible to cook the food with the oxidation suppressed. Here, the state of low oxygen refers to a state in which the volume percentage of oxygen is 10% or less (e.g., 0.5 to 3%) in the heating chamber.

  Although the specific embodiment of this invention was described, this invention is not limited to the said 1st-5th embodiment, It can change variously within the scope of this invention, and can be implemented.
