Field of the Invention The present invention relates to a force π thermal conditioner having an operation panel below a door of a switch heating chamber. [Prior Art] In the heating conditioner, in order to further increase the volume of the heating chamber, the mechanical chamber is placed in the lower portion and the portion of the cabinet, so that the entire front of the cabinet is substantially The constitutive type. In this heating conditioner, the 'operation panel' is also disposed on the door, but since the heating chamber is located at the door, the paste is subjected to heating conditioning using an electric heater as a heating device. Heating causes the temperature of the operation panel portion to also rise. Further, since the temperature in the hot chamber is higher in temperature, the temperature of the surface is also increased toward the upper portion. Therefore, the operation panel portion is disposed at the lower portion of the door in order to avoid an increase in the degree of twist. , t, that in the stocking 敝 offer ^ patent read 2 towels, revealing the above == plus _ _ | | _ child. In the special distribution, it is the left and right side of the operating surface (4), the display part and the falling touch operation knob [Patent Document 2] Japanese Patent Laid-Open No. 7 1291005, 21177pif.doc No. 309060 Bulletin (see FIG. 3) However, in the above-described conventional heating conditioner, there are the following problems. In other words, when the operation panel portion is provided in the lower portion of the door, as shown in Patent Document 1, when the display and the known key are disposed on the right and left sides of the operation panel portion, the heating and conditioning treatment is performed as described above. Since a relatively high temperature is formed upward from the central portion of the door, there is a problem that the surface of the operation key disposed near the center of the door forms a high temperature. Further, as shown in Patent Document 2, when the display unit, the operation keys, and the operation knob are arranged side by side in a narrow region in the lower portion of the door in the same manner, since the center of the door is further spaced, the operation key due to heat conduction can be suppressed. The temperature of the surface rises, but the size of the display portion and the operation key (S1ze) has to be small, and the operation key is difficult to operate.

The function of the present embodiment is also referred to in FIG. 3 and FIG. 4, and the conditioning is performed. * The heating conditioning by the heater heating unit 8 is performed, that is, the supply port is closed in the week, and the user opens the door 4 to set the room 2 Inside and close Π4. ^ When the object to be heated is placed in the heating line, the μ is selected, and the knob 13 and the operation button 15 are used to adjust the time and the conditioning temperature. Further, this π and the temperature 荨 are displayed on the display unit 12. The device is highlighted here; the operation of the operation operator is improved, and the operation of the operation key 15 is hindered. Then, the start key 14 can be operated at all times to start the tank conditioning. After σίΜδ and 疋元成成, according to Likai 12 1291005, 2lJ77pif.doc, after the oven conditioning is started, the object to be heated stored in the heating chamber 2 is heated by the heat generated by the heater heating portion 8. Therefore, since the heat is also transferred to the crucible 4, the door 4 is also heated, and the temperature of the operation panel 11 is also raised. Here, Fig. 4 shows an example of the state of temperature distribution in the door portion of the oven conditioning. As shown in FIG. 4, the temperature of the door and w tends to be the highest from the region 稍1 slightly upward from the center thereof, and from here, the direction is decreased toward the periphery in the order of the regions A2 to A4, compared with the region A4. The outer area, that is, the temperature below the door 4, becomes the lowest. In the operation panel portion n❸ area disposed below the door 4, the position and side operation keys 15 can suppress the temperature rise of the operator surface. On the other hand, the operation knob 13 and the start key 14 are disposed on the right side of the operation surface = 11, but since the resin having a relatively low thermal conductivity is formed, the heat from the door 4 can be suppressed from propagating. Further, the operator of the 白 白 white and the start key M is a front-facing shape of the door 4, so that the temperature rise of the operation surface is also suppressed. Wensheng ίΓ has to change the conditioning time and conditioning on the way of this oven conditioning: when the condition is met, or after the conditioning of the box is finished In this case, the temperature of each of the operation surfaces, or the opening = two = comfortable operation of the two and the use of the present embodiment as described above, the formation of a = the front of the entire formation of the heating chamber 2 == = In the case of the panel portion 11, the operation key 15 is suppressed by the operation of the operation key 15 in the case of 13 !291 〇〇 5 21177 pif.d 〇 c in the operation panel portion U. The temperature of the operator's surface did not rise during the operation of the vessel. Moreover, the front facing core 1 = the configured operating knob 13 forms a kind of gate operator surface 13, and can also be suppressed to change the setting wood during the execution or after the check of the chess box. The operation key is obstructed;; 'two can not feel the operation and 'because the left- 2' in the operation panel portion u and the operation knob 13 are disposed on the upper right side, the go-no-turn knob 13 is operated to set up In the case of the operation, etc., it is possible to see the display of the display unit 12, and to display the display unit 12 with a high frequency. Constructing wood: There are eight clocks from the door] 5 l·s α constituting 'and arranged above the key 15 of the door, so that the operation can be suppressed and the operability is improved. In addition, the degree of thermal conductivity of the glass which is lower in the operation of the screw and the start of the operation of the glass is reduced by the influence of the heat transmitted by the surface constituting the crucible. In addition, since the temperature of the surface of the known actuator is suppressed and the input operation is performed by the operation knob 13, it is possible to increase the size of the pressing operation of each of the key types by using the operation key 15 repeatedly.
