Embodiment 1
Hereinafter, an embodiment of the present invention will be described in detail. FIG. 1 is a perspective view showing a configuration of a heating cooker 1A according to the present embodiment. Moreover, FIG. 2 is a perspective view which shows the structure inside the heating cooker 1A. Moreover, (a) of FIG. 3 is sectional drawing which shows the structure of 1 A of heating cookers.

As shown in FIGS. 1 to 3A, the heating cooker 1A includes a heating furnace 20, a steam generation unit 30, a net member 4, and a water supply unit 50. Further, the heating furnace 20, the steam generation unit 30, the net member 4, and the water supply unit 50 are accommodated in the housing 6. The housing 6 has a quadrangular prism shape having a square bottom surface.

The heating furnace 20 is a concave container having an open portion 21 at the top. In the heating cooker 1A according to the present embodiment, the heating furnace 20 is in the form of a square container. A steam outlet 22 is provided on the inner surface of each of the four side walls 23 of the heating furnace 20.

The mesh member 4 has a mesh structure, and is provided so that the upper surface thereof is located in the open portion 21 of the heating furnace 20. The net member 4 is in the form of a container that matches the shape of the upper portion of the heating furnace 20, and a heated object such as a food that is a cooking target of the heating cooker 1A is placed on the bottom surface. The bottom surface of the net member 4 is located below the open portion 21 of the heating furnace 20. The object to be heated placed on the bottom surface of the net member 4 can be turned over or moved through the opening 21 using, for example, a chopping tool, a tongue or the like.

The steam generating unit 30 is a device that generates superheated steam to be supplied to the heating furnace 20, and is provided on the outer surface of each of the four side walls 23 constituting the heating furnace 20.

Four water supply units 50 are provided corresponding to the steam generation unit 30. The water supply unit 50 includes a water supply tube 51 connected to the steam generation unit 30, and supplies water to the steam generation unit 30. The water supply unit 50 includes a water supply pump (not shown), a water supply tank (not shown), and the like.

The superheated steam generated by the four steam generating units 30 is supplied into the heating furnace 20 through the steam outlet 22 provided on the inner surface of the side wall 23 of the heating furnace 20. The superheated steam supplied from the steam outlet 22 fills the space below the open portion 21 of the heating furnace 20. At this time, the object to be heated placed on the mesh member 4 is cooked by superheated steam filled in a space below the opening 21.

FIG. 4 is a cross-sectional view showing the configuration of the steam generating unit 30 in the heating cooker 1A according to the present embodiment. In FIG. 4, the switching unit 35 is schematically illustrated.

As shown in FIG. 4, the steam generating unit 30 includes a steam generating heater 31 (first heater), a superheated steam generating heater 32 (second heater), the steam generating heater 31, and the superheater. And a switching unit 35 that independently switches on / off the water vapor generating heater 32. The steam generating unit 30 is configured as a unit in which a steam generating heater 31 and a superheated steam generating heater 32 are incorporated in a housing 33. A partition wall 33 C is provided in the housing 33. The partition wall 33C divides the internal space of the housing 33 into a steam generation space 33A in which the steam generation heater 31 is accommodated and a superheated steam generation space 33B in which the superheated steam generation heater 32 is accommodated. .

The partition wall 33C has a base material made of heat-resistant stainless steel such as SUS304 (18 chrome stainless steel) and a film covering the base material. This film has heat resistance and is formed by, for example, black coating.

The superheated steam generation space 33B is provided in the steam generation space 33A. The steam generation space 33A and the superheated steam generation space 33B communicate with each other so that steam can enter and exit. The superheated steam generation space 33 B is provided with a steam discharge pipe 34 that communicates with the space in the heating furnace 20. The steam discharge pipe 34 is provided so as to penetrate the steam outlet 22 of the heating furnace 20.

The housing 33 has a base material cast by a metal die casting method such as aluminum, and a coating covering the base material. This film has water repellency and prevents the precipitation of oxides such as rust from the surface of the substrate. This film is formed by painting, for example.

Water from the water supply unit 50 is dripped into the housing 33 of the steam generation unit 30. The steam generating heater 31 heats the housing 33 and evaporates the water dropped on the housing 33. Thereby, about 100 degreeC saturated water vapor | steam generate | occur | produces in the steam generation space 33A.

Here, the steam generating heater 31 is cast in the housing 33. Therefore, the contact area between the steam generating heater 31 and the housing 33 can be increased. As a result, the heat of the steam generating heater 31 can be efficiently transmitted to the housing 33, and the evaporation efficiency is improved.

Saturated steam generated in the steam generation space 33A flows into the superheated steam generation space 33B. Then, in the superheated steam generation space 33B, the superheated steam is heated by the superheated steam generation heater 32 to become overheated steam of 100 ° C. or higher (for example, about 300 ° C.). Here, the superheated steam means steam heated to a superheated state of 100 ° C. or higher. The superheated steam generated in the superheated steam generation space 33 B passes through the steam discharge pipe 34 and is supplied to the heating furnace 20.

Thus, the object to be heated placed on the mesh member 4 is cooked by superheated steam at 100 ° C. or higher (for example, about 300 ° C.) blown out from the steam outlet 22 of the heating furnace 20. At this time, superheated steam is supplied to and adhered to the surface of the object to be heated, condenses on the surface of the object to be heated, and gives a large amount of condensation latent heat to the object to be heated. Therefore, heat can be efficiently transferred to the object to be heated.

Moreover, in the heating cooker 1A, since cooking is performed using superheated steam, it is possible to suppress moisture from evaporating from the heated object and drying. Therefore, the object to be heated can be cooked in a moist finish that retains moderate moisture.

Further, according to the heating cooker 1 A, the bottom surface of the mesh member 4 on which the object to be heated is placed is located below the open portion 21 of the heating furnace 20. And the to-be-heated material mounted in the net | network member 4 can be turned over or moved through the open part 21, for example using a chopping and a tong. Therefore, the object to be heated heated by the superheated steam can be easily operated according to the heating situation.

Therefore, according to the configuration of the heating cooker 1A, it is possible to cook by using superheated steam while easily operating the object to be heated during cooking. The cooking device 1A is a completely new cooking device that has the advantages of both a grilled cooking device and an oven cooking device using superheated steam.

Moreover, in the heating cooker 1A, cooking using only superheated steam is possible. On the other hand, an oven-type heating cooker using superheated steam cooks by using radiant heat of a heating chamber heated by a heater in addition to superheated steam.

Unlike the oven-type heating cooker using superheated steam, the heating cooker 1A is configured to supply superheated steam in a heating furnace 20 (non-sealed space) having an open portion 21 communicating with the outside. Moreover, the heating cooker 1A is configured to heat and cook an object to be heated only with superheated steam. The steam generation unit 30 continues to generate superheated steam to heat the object to be heated placed on the mesh member 4, but senses the heating condition of the object to be heated using a sensor or the like, and generates superheated steam. May be controlled.

Further, as shown in FIG. 4, the steam generation unit 30 includes a switching unit 35 that independently switches on / off of the steam generation heater 31 and the superheated steam generation heater 32. Therefore, in the heating cooker 1A, both heating cooking using superheated steam and steaming cooking using saturated steam can be performed.

When steaming and cooking the object to be heated, the switching unit 35 controls to turn on the heater 31 for generating steam and to turn off the heater 32 for generating superheated steam. Thereby, the steam generation unit 30 supplies the saturated steam generated by the steam generation heater 31 to the inside of the heating furnace 20. In the heating furnace 20, the space below the open portion 21 is filled with saturated steam, and steamed cooking of the object to be heated placed on the mesh member 4 becomes possible.

When the object to be heated is cooked with superheated steam, the switching unit 35 controls to turn on both the steam generating heater 31 and the superheated steam generating heater 32. Thereby, the steam generation unit 30 supplies the superheated steam generated by the superheated steam generation heater 32 to the inside of the heating furnace 20. In the heating furnace 20, the space below the open portion 21 is filled with superheated steam, and the object to be heated placed on the net member 4 can be cooked with superheated steam.

Thus, in the heating cooker 1A, healthy cooking can be performed by using superheated steam or saturated steam. In the heating cooker 1 A, superheated steam or saturated steam is supplied to the surface of the object to be heated placed on the mesh member 4. And superheated steam or saturated steam adheres to the surface of the object to be heated as condensed water. Thereby, the salt or oil in the heated object is dropped together with the condensed water adhering to the surface of the heated object. As a result, it is possible to reduce salt or oil in the heated object.

Furthermore, since the steam generation unit 30 continues to generate superheated steam or saturated steam to heat the object to be heated placed on the mesh member 4, the steam generation unit 30 around the object to be heated placed on the mesh member 4 The space is filled with superheated steam or saturated steam and becomes oxygen-free. Thereby, the heat cooking which suppressed the oxidation of the to-be-heated material is attained.

Moreover, in the heating cooker 1A according to the present embodiment, the steam outlet 22 that blows out superheated steam or saturated steam is provided only on the inner surface of the side wall 23 of the heating furnace 20. No heat source such as a steam outlet 22 or a heater is provided on the bottom surface 24 located immediately below the object to be heated placed on the net member 4. Thereby, even if the fats and oils or juice which came out of the to-be-heated material dripped during the cooking process, it is possible to prevent these oils and fats from being heated and producing smoke.

Moreover, the heating cooker 1 A may include a lid member that covers the open portion 21 of the heating furnace 20. And according to the kind of to-be-heated material, you may make it perform the cooking using a cover member. For example, when cooking food that is difficult for heat to pass through, cooking is performed with the lid 21 covering the open portion 21 of the heating furnace 20 in order to efficiently heat the object to be heated.

The member on which the object to be heated is placed is not limited to the net member 4 having a mesh structure, and the support that can support the object to be heated at the open portion 21 of the heating furnace 20 or a position below the open portion 21. If it is a member, it will not specifically limit. For example, a tray etc. are mentioned as a supporting member which supports a to-be-heated material.

The mesh member 4 supports the object to be heated so as to come into contact with the superheated steam filled in the heating furnace 20 by the mesh structure. Therefore, the object to be heated can be cooked without unevenness.

Further, as shown in FIG. 1 to FIG. 3A, the inner surface of the side wall 23 of the heating furnace 20 is inclined with respect to the bottom surface 24. More specifically, the side wall 23 of the heating furnace 20 is configured such that the interval between the inner surfaces of the side walls 23 facing each other becomes narrower toward the bottom surface 24.

With such a configuration, it becomes possible to blow superheated steam obliquely upward from the steam outlet 22. Therefore, the object to be heated placed on the mesh member 4 can be easily cooked from below.

In the configuration shown in FIGS. 1 to 3A, the cooking device 1A is provided with the steam outlet 22 only on the inner surface of the side wall 23 of the heating furnace 20. However, the steam outlet 22 should just be arrange | positioned in the heating furnace 20 so that the fats and oils dripped from the to-be-heated material in the cooking process may be avoided.

FIG. 3 (b) is a plan view schematically showing an example of the arrangement of the steam outlets 22 which is different from the configuration shown in FIGS. 1 to 3 (a). As shown in FIG. 3B, the steam outlet 22 may be provided on the bottom surface 24 of the heating furnace 20. The steam outlet 22 is preferably provided on the outer peripheral side of the bottom surface 24 with respect to the region overlapping the bottom surface 41 of the net member 4.

The fat or juice from the object to be heated during the cooking process can be dropped on the bottom surface 24 of the heating furnace 20 in a region overlapping with the bottom surface 41 of the net member 4. According to the configuration shown in FIG. 3B, the steam outlet 22 is provided on the outer peripheral side of the bottom surface 24 with respect to the region overlapping with the bottom surface 41 of the mesh member 4, so that the oil or juice is not It is possible to prevent smoke from being heated.
