Description

This invention relates to a heating and cooking apparatus, and more particularly to a heating and cooking apparatus that utilizes hydrogen. Conventional cooking devices that use superheated steam to cook food have been known (see, for example, Patent Document 1). Japanese Patent Publication No. 2013-015272 This is a schematic diagram showing the general configuration of a hydrogen oven as a heating and cooking device according to the first embodiment of the present invention.Figure 1 is a schematic diagram showing the internal structure of the hydrogen oven.This is a schematic perspective view showing the configuration of the hydrogen burner nozzle in a hydrogen oven.Figure 3 is a cross-sectional perspective view of the pipeline of the ejector shown.This is a schematic diagram illustrating the general configuration of a hydrogen oven.This figure shows a schematic configuration of a hydrogen oven according to a second embodiment of the present invention. The embodiments of the present invention will be described below with reference to the drawings. Note that not all of the multiple components in the drawings are denoted by reference numerals, and some reference numerals for multiple components are omitted. Figure 1 shows a schematic configuration of a hydrogen oven 1 as a heating and cooking device according to the first embodiment of the present invention, and Figure 2 shows a schematic internal structure of the hydrogen oven 1. As shown in Figures 1 and 2, the hydrogen oven 1 comprises a hydrogen burner 2 for burning hydrogen gas, a heating chamber 3 which is a space for cooking food ingredients M, and an air intake 4 capable of supplying air to the heating chamber 3. The hydrogen burner 2 is located inside the heating chamber 3. The configuration of the hydrogen oven 1 will be described in detail below. As shown in Figures 1 and 2, the hydrogen oven 1 has, for example, a main body cover 20, which is a member that covers the heating chamber 3. The main body cover 20 forms a space that is closed or approximately closed to the outside, defining the heating chamber 3. The main body cover 20 has, for example, an inlet 21 and an outlet 22, which are openings through which the conveying unit 5 (described later) passes. The inlet 21 and outlet 22 may be fitted with lids that allow them to be opened and closed. As shown in Figures 1 and 2, the hydrogen oven 1 includes a conveying section 5 capable of transporting, for example, food ingredients M. The conveying section 5 passes through the heating chamber 3 and is capable of transporting the food ingredients M horizontally or substantially horizontally. The conveying section 5 is, for example, a belt conveyor. Specifically, as shown in Figure 1, the conveying section 5 is constructed by winding an endless metal belt 5c around a pair of sprockets 5a and 5b. Furthermore, for example, one or both of the pair of sprockets 5a and 5b are designed to rotate. The conveying section 5 penetrates the main body cover 20 through the inlet 21 and outlet 22 of the main body cover 20. The conveying section 5 is composed of, for example, multiple belt conveyors connected together. As described above, a hydrogen burner 2 is positioned in the heating chamber 3. The hydrogen burner 2 is configured, for example, to sandwich the conveying unit 5 from above and below within the heating chamber 3. The hydrogen burner 2 has a pair of nozzles 10, as shown in Figures 1 and 2. One nozzle 10 is located above the conveying unit 5, and the other nozzle 10 is located below the conveying unit 5. Furthermore, as shown in Figures 1 and 2, the pair of nozzles 10 face each other vertically via the conveying unit 5. The nozzles 10 are capable of supplying hydrogen gas and ejecting the supplied hydrogen gas to the outside. As shown in Figures 1, 2, and 3, the ejector body 10 has multiple conduits 11. As shown in Figure 4, the conduits 11 have a space 12 through which gas can be supplied, and also have multiple openings 13 that open the space 12 to the outside. The openings 13 are arranged such that, for example, the velocity at which the gas supplied to the conduits 11 exits the openings 13 is greater than the combustion velocity of the hydrogen gas. Figure 3 is a schematic perspective view showing the configuration of the ejector body 10, and Figure 4 is a cross-sectional perspective view of the conduits 11 of the ejector body 10. As shown in Figure 3, the ejector 10 has, for example, a buffer pipeline 14. The buffer pipeline 14 has an internal space, as shown in Figure 5. That is, the buffer pipeline 14 has a space extending in its direction of extension, allowing gas to be guided along the direction of extension of the buffer pipeline 14. Furthermore, the buffer pipeline 14 is shaped to temporarily store the gas supplied to the space and maintain a constant or approximately constant pressure within the space. As shown in Figure 3, the buffer pipeline 14 is provided with multiple pipelines 11 project
