Fig. 6 is the control block diagram of above-mentioned heating device.
Above-mentioned heating device has the control device 100 be made up of microcomputer and imput output circuit etc. in door 3 (shown in Fig. 1 ~ Fig. 3).Above-mentioned control device 100 and magnetron 4, guidance panel 9, supply-water pump 15, saturated steam generation device 16, overheated steam generate heater 17, door opening and closing state test section 18, first light emitting diode 304A and the second light emitting diode 304B etc. and are connected.Above-mentioned control device 100, based on the signal etc. from guidance panel 9 and door opening and closing state test section 18 etc., controls magnetron 4, guidance panel 9, supply-water pump 15, saturated steam generation device 16, overheated steam generation heater 17, first light emitting diode 304A and the second light emitting diode 304B etc.Such as, when door 3 is closed, control device 100 makes the first light emitting diode 304A disconnect and make the second light emitting diode 304B conducting.Further, when door 3 is opened, control device 100 makes the first light emitting diode 304A conducting and the second light emitting diode 304B is disconnected.In addition, make the first light emitting diode 304A conducting and make second light emitting diode 304B disconnect opportunity also can be such as remove door 3 close after, can also be door 3 half-open time.As long as that is, above-mentioned opportunity from releasing door 3 close after open completely to door 3 during, can be any opportunity.
Above-mentioned supply-water pump 15 sucks the water in water supply container 19 (shown in Fig. 1), and is carried to saturated steam generation device 16 by above-mentioned water.Above-mentioned saturated steam generation device 16 heats the water from supply-water pump 15 and becomes saturated steam, and supplies in heating clamber 102 or supply to overheated steam generation heater 17.There is provided saturated steam by generating heater 17 from saturated steam generation device 16 to overheated steam, above-mentioned saturated steam can be made overheated and become overheated steam and supply in heating clamber 102.At this, above-mentioned overheated steam refers to the steam of the superheat state being heated to more than 100 DEG C.
The state that state, door 3 that above-mentioned door opening and closing state test section 18 detecting gate 3 is opened completely are not exclusively opened and the state that door 3 is closed.Above-mentioned door opening and closing state test section 18 is such as made up of multiple button, encoder etc.At this, the state that door 3 is not exclusively opened is such as half-open position, refers to the state between the state that door 3 is opened completely and the state that door 3 is closed.
According to the heating device of said structure, due to be configured with in the first light emitting diode 304A, light path between the second light emitting diode 304B and heating clamber 2 transparent in glass 305, so entered in heating clamber 2 by interior glass 305 from the light of the first light emitting diode 304A, the second light emitting diode 304B.Therefore, though not in the setting example below of door 3 as through hole, also can make the first light emitting diode 304A, the light of the second light emitting diode 304B enters in heating clamber 2.Its result, can prevent the steam in heating clamber 2 from spilling outside heating clamber 2, thus manufacturing cost can be suppressed to rise.
In addition, at above-mentioned first light emitting diode 304A, the punch metal plate 306 being configured with the microwave blocked from heating clamber 2 side between the second light emitting diode 304B and interior glass 305.Thus, the first light emitting diode 304A can be prevented, the second light emitting diode 304B broken down by heating using microwave.
In addition, due to the cooling fan 307 that above-mentioned door 3 has Color Liquid Crystal Display portion 10, above-mentioned first light emitting diode 304A, the second light emitting diode 304B and cools Color Liquid Crystal Display portion 10, so can prevent the first light emitting diode 304A, the second light emitting diode 304B and Color Liquid Crystal Display portion 10 from breaking down because of the heat from heating clamber 2.
In addition, because the air of cooling fan 307 blowout is by Color Liquid Crystal Display portion 10 with between the first light emitting diode 304A, the second light emitting diode 304B, so can effectively cool Color Liquid Crystal Display portion 10 and the first light emitting diode 304A, the second light emitting diode 304B.

In addition, above-mentioned first light emitting diode 304 is for illuminating in heating clamber 2 when door 3 is opened, and the second light emitting diode 304B is used for illuminating in heating clamber 2 when door 3 is closed.Thus, no matter door 3 is opened or closes, and can both be illuminated in heating clamber 2.
In addition, when above-mentioned door 3 is opened, the first light emitting diode 304A conducting and the second light emitting diode 304B disconnects.Thus, power consumption during heating clamber 2 intraoral illumination is reduced.
In addition, be close on the position of heating clamber 2 side than the second light emitting diode 304B because above-mentioned first light emitting diode 304A is arranged on when door 3 is opened, so can effectively illuminate in heating clamber 2.
In the above-described first embodiment, utilize the first light emitting diode 304A, illumination that the second light emitting diode 304B carries out in heating clamber 2, but also can use-case such as organic EL (electroluminescent) or Halogen lamp LED etc. throw light on.
In the above-described first embodiment, heating device has magnetron 4, but also can not possess magnetron 4.In this case, can not at the first light emitting diode 304A, configure punch metal plate 306 between the second light emitting diode 304B and interior glass 305.
In the above-described first embodiment, when door 3 is closed, the aspect ratio second light emitting diode 304A of the opening portion 306a near the second light emitting diode 304A is low, but this highly also can be substantially identical with the second light emitting diode 304A.
In the above-described first embodiment, when door 3 is opened, control device 100 makes the first light emitting diode 304A conducting and the second light emitting diode 304B is disconnected, but also can make the first light emitting diode 304A, the second light emitting diode 304B both sides disconnect.
In the above-described first embodiment, if at least add hanker drive cooling fan 307.
In the above-described first embodiment, the shape of the through hole of punch metal plate 306 can be any one shape in circle, rectangle, ellipse etc.
[the second embodiment]
The heating device of second embodiment of the invention and the difference of the first embodiment are only: when door 3 is opened, the optical axis of the first light emitting diode 304A tilts relative to horizontal direction, thus door 3 is when opening wide, effectively illuminated in heating clamber 2 by the first light emitting diode 304A.
