[Brief explanation of the drawings]

[0008] [Figure 1] 1A and 1B show a cooking appliance for heating according to an embodiment of the present invention, in which (A) is a front view and (B) is a cross-sectional view taken along line AA of (A). DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, a cooking appliance according to an embodiment of the present disclosure will be described with reference to the drawings. The cooking appliance according to the present embodiment includes a heating unit for heating an object to be heated, a housing having an inlet for introducing the object to be heated and a heating chamber for heating the object introduced through the inlet, and a light source for irradiating the object introduced into the heating chamber with ultraviolet light in a wavelength band of 280 nm or more and 315 nm or less.

[0010] As shown in FIGS. 1(A) and 1(B), the cooking appliance 1 according to this embodiment is an electric oven range, and includes a housing 11 that forms the outer shell of the cooking appliance 1, and a light source 14. An operating unit 21 that is operated by a user of the cooking appliance 1 is provided on the outside of the housing 11. The housing 11 has a heating chamber S1 and a storage chamber S2. The heating chamber S1 is provided with an insertion port 11a for inserting an object to be heated SP, and is used to heat the object SP inserted into the heating chamber S1 through the insertion port 11a. The storage chamber S2 is disposed on the side opposite the insertion port 11a of the heating chamber S1, via a partition plate 17 having a plurality of holes 17a formed therein, and a lamp heater 16 is disposed inside the storage chamber S2. A door 12 is attached to the housing 11 so as to cover the insertion port 11a of the heating chamber S1.

[0011] The cooking appliance 1 also includes a table 131 disposed below the heating chamber S1 on which the object to be heated SP is placed, and a blower fan 151 stored in the storage chamber S2 for circulating the high-temperature air present in the heating chamber S1. The heating chamber S1 and the storage chamber S2 are separated by a partition plate 17, and the partition plate 17 is provided with a plurality of intake holes 17a for drawing the air in the heating chamber S1 into the storage chamber S2, and a plurality of exhaust holes 17b for discharging the air drawn into the storage chamber S2 toward the heating chamber S1.

[0012] Furthermore, the cooking appliance 1 includes a magnetron 134 that generates microwaves for microwave cooking, a waveguide (not shown) that guides the microwaves, an antenna 133 that irradiates the microwaves into the heating chamber S1, and an antenna driver 132 that rotates the antenna 133. When cooking an object SP to be heated in a microwave oven, the microwaves generated by the magnetron 134 propagate through the waveguide and are irradiated into the heating chamber S1 via the antenna 133. Here, the antenna driver 132 irradiates the microwaves into the heating chamber S1 while rotating the antenna 133, so that the microwaves are irradiated uniformly into the heating chamber S1, and uneven heating of the object SP can be suppressed.

[0013] The cooking appliance 1 also includes a lamp heater 16 disposed within the storage chamber S2 for heating the air within the heating chamber S1 during oven cooking of the object to be heated SP, a rotatable air blower fan 151 disposed approximately in the center of the storage chamber S2, and a fan motor 152 for driving the air blower fan 151. The fan motor 152 drives the air blower fan 151 to rotate, drawing air from the heating chamber S1 into the storage chamber S2 through a plurality of intake holes 17a. The air is then heated by the lamp heater 16, and the heated air is blown out into the heating chamber S1 through the exhaust holes 17b, thereby raising the temperature of the air within the heating chamber S1. Furthermore, since the air blower fan 151 is disposed approximately in the center of the storage chamber S2, it agitates the air within the storage chamber S2, reducing temperature variations in the air exhausted from the storage chamber S2 through the exhaust holes 17b. This allows the object to be heated SP disposed within the heating chamber S1 to be cooked evenly. The lamp heater 16, the blower fan 151, etc. constitute a heating means for heating the object to be heated SP by heating the air in the heating chamber S1.

[0014] The light source 14 is disposed above the heating chamber S1 and emits ultraviolet light in a wavelength band of 280 nm to 315 nm. The light source 14 irradiates the object to be heated SP with ultraviolet light so that the cumulative light intensity is constant. The cumulative light intensity of the ultraviolet light per cooking of the object to be heated SP is preferably 45 mJ / cm2 or more. The light source 14 has, for example, an elongated straight tube shape. The shape and number of the light sources 14 are not particularly limited. For example, they may be current-type light sources, and the number of light sources may be one or more. A shielding member 18 that blocks microwaves during cooking using the microwave oven is disposed inside the housing 11 so as to cover the light source 14. The shielding member 18 transmits at least a portion of the ultraviolet light emitted from the light source 14 and prevents microwaves irradiated from the antenna 133 into the heating chamber S1 from penetrating inward. The shielding member 18 has, for example, a mesh-like structure formed from thin metal wires.

[0015] Furthermore, the cooking appliance 1 includes a control unit 19 that controls the operation of the antenna driving unit 132, the lamp heater 16, the fan motor 152, the light source 14, etc. in response to an operation on the operating unit 21 by the user.

[0016] According to the cooking utensil 1 of the present embodiment, the food SP is heated while being irradiated with ultraviolet light in the wavelength band of 280 nm or more and 315 nm or less. This allows the food SP to be cooked and the amount of vitamin D contained in the food SP to be increased at the same time.

[0017] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments. For example, after the object to be heated SP is placed in the heating chamber S1, the control unit 19 may turn on the light source 14 and irradiate the object to be heated SP with ultraviolet light for a preset time before starting microwave cooking or oven cooking, and then turn off the light source 14 before starting microwave cooking or oven cooking.

[0018] In the embodiment, an example of the cooking appliance 1 is described as an electric oven range, but the cooking appliance is not limited to this and may have only either an oven function or a microwave function. Here, if the cooking appliance has only an oven function, it may not have a configuration that includes the shielding member 18. Furthermore, the cooking appliance according to the present invention may be a cooking appliance that cooks food using steam, for example.

[0019] Although the embodiments and modifications of the present invention have been described above, the present invention is not limited to these. The present invention includes any combination of the embodiments and modifications, and any combination to which appropriate modifications have been made. [Industrial Applicability]

[0020] The present invention is suitable for heat cooking, which heats food and increases the amount of vitamin D contained in the food. [Explanation of symbols]
