After the installation, the baking oven 4 and the operation unit panel 5, which will be described later, of the heating conditioner 2 can be operated from the front portion of the system kitchenware 1.

A pot (not shown) for performing the object to be heated at the time of conditioning is placed on the panel 3, and the substrate of the panel 3 is made of a non-crystallized glass disposed on the upper surface of the main body 2, and at least three heat-resistant temperatures are used. Hundreds of degrees of heat-resistant paint are applied on the inner surface with a text or a substantially full-surface coating, and the surface is printed with a glass-slip effect.

The conditioning pot (not shown) is placed on the mounting portion 6 drawn on the panel 3 to be conditioned. The mounting portion 6 has a right mounting portion 6a and a left mounting portion 6b disposed on the upper surface of the upper surface of the panel 3 on the upper surface of the main body 2. The inner side (the center rear portion) between the two mounting portions 6a and 6b is disposed at the center. The portion 6c. Further, a heating coil unit 25, which will be described later, for heating the conditioning pot is provided below each of the mounting portions 6 via the panel 3.

The central placing portion 6c is a position where the hand of the conditioner is not easily reached. Therefore, when the conditioning pot is placed on the right side of the right mounting portion 6a and the left mounting portion 6b, if the hand is extended toward the center mounting portion 6c, the conditioning performed by the center mounting portion 6c may be performed. The steam generated in the conditioning pot placed on the right mounting portion 6a and the left loading portion 6b is not easily performed. Therefore, the type of conditioning performed in the central placement unit 6c is suitable for dishes that do not require the care of the conditioner, and are mainly conditioning such as stewing or heat preservation. Also, the firepower does not need to be too large when stewing or keeping warm, and the maximum power consumption is also Therefore, the heating power of the heating coil 13c provided in the center mounting portion 6c is set to be weaker than the right heating coil 13a and the left heating coil 13b provided corresponding to the right mounting portion 6a and the left mounting portion 6b, so as to be consumed. The power is getting smaller.

In the first and second figures, a frame 14 is provided to protect the peripheral end surface of the panel 3. The frame 14 is a front frame 14a attached to an upper end edge of the panel 3; a rear frame 14b attached to an upper end edge of the panel 3; a right frame 14c attached to the upper right edge; and a left side mounted to the upper left edge The frame 14d is constructed. In this example, the frame is divided into four parts, but it can also be an integral type, a two-piece type, or any number of pieces, and it does not need to be installed on the four sides of the panel 3, or only the front side of the panel 3, only the rear side. There are only front and rear sides or only the left and right sides.

In the main body 2, a heating coil unit 25 and an electronic component, which will be described later, as heat generating members are provided, and in order to cool these, an intake port 7 for taking in air from the outside of the main body 2 is provided. The intake port 7 shown in the figure is disposed on the right side opposite to the exhaust port 8 which will be described later on the rear frame 14b on the upper surface of the main body 2. However, in order to prevent suction of steam from the pan or to attract water droplets ejected by boiling, it may not be provided. On the upper side of the main body 2, the suction port is provided on the side of the operation panel 5.

The air sucked in the intake port 7 is cooled by a heating coil unit 25 or an electronic component, which will be described later, inside the main body 2, and then discharged from the exhaust port 8 to the outside of the main body. Further, waste heat of the baking oven 4 to be described later is simultaneously discharged from the exhaust port 8, and the exhaust port 8 is provided on the rear frame 14b on the upper surface of the main body 2 on the side where the baking oven 4 is located.

The baking oven 4 is for grilling fish or pizza, etc., and therefore is disposed on the left side or the right side of the front portion of the main body 2. This embodiment is configured to face the front of the main body 2. on the left. Moreover, since it is not exclusive to grilled fish, the baking oven 4 is sometimes called a grill or an oven.

The baking oven 4 will be described using Fig. 5 .

The conditioning chamber 26 is formed in a box shape having an open front, and an upper heating element 27 and a lower heating element 28 each composed of a heating element such as an electric heating tube heater are provided inside. An exhaust outlet 29 is provided at the upper rear portion of the conditioning chamber 26. Further, although the heating element is an embodiment in which the upper heating element 27 and the lower heating element 28 are provided, the upper heating element 27 may be provided. However, in this case, it is necessary to turn the conditioner 30 over the middle of baking.

A handle 11 is attached to the front side of the baking oven door 32 for sealing the opening portion of the conditioning chamber 26, and a tray 31 is attached to the inside. The tray 31 is housed in the conditioning chamber 26 so as to be freely accessible from the front opening. On the other hand, a grill 33 is placed in the tray 31 for placing the conditioner 30 such as fish thereon.

The conditioning reservoir 26 is provided with an air purifying catalyst 34 for purifying the smoke or odor generated when the conditioning material 30 is baked. The air purifying catalyst 34 is installed such that the smoke or odor entering from the exhaust outlet 29 must pass through the air purifying catalyst 34.

When the exhaust fan 36 is operated, air flows into the conditioning chamber 26 via the air intake port 42 provided between the tray 31 and the baking oven door 32. The inflowing air is discharged from the exhaust port 8 to the outside via the air purifying catalyst 34 and the exhaust passage 35 together with the smoke or odor generated inside the conditioning chamber 26. By the catalytic action of the air-purifying catalyst 34, the odor or smoke generated in the conditioning chamber 26 is reduced in accordance with the ability of the catalyst, and the exhaust port is exhausted. 8 forced to be discharged.

The catalyst heater 37 for heating the air purifying catalyst 34 is provided in the conditioning chamber 26 in the vicinity of the air purifying catalyst 34. Thereby, the air purifying catalyst 34 is heated, and the catalytic action is exerted.

The temperature in the conditioning chamber 26 is detected by a temperature detecting means 38 such as a thermistor provided on the upper portion of the front surface of the conditioning chamber 26 and the lower portion of the side surface of the tray 31.

In the case of a single-sided baking rack provided with a heater only in the upper portion, in order to prevent the temperature of the tray 31 from rising, it is necessary to put water in the tray 31 and then to bake. This embodiment is for cooling the tray 31 without water, and a cooling passage 39 is provided at the lower portion of the tray 31. When the suction fan 40 rotates, the air that has flowed in from the air intake port 42 passes through the lower portion of the tray 31, and the tray 31 is cooled and then discharged from the exhaust port 8 via the inside of the back surface of the conditioning chamber 26.

The exhaust fan 36 and the suction fan 40 are driven by a motor 41 provided at a lower portion of the rear frame 14b. The exhaust fan 36 and the suction fan 40 are directly mounted on the shaft of the motor 41. The cooling of the motor 41 is performed by a self-cooling fan 43 provided on the other end side of the motor 41.

The electric motor 41 and the self-cooling fan 43 are disposed in the lower portion of the rear frame 14b, and are disposed in the heat insulating chamber 44 provided at the rear of the main body 2. The heat insulating chamber 44 is provided with an air inflow port 45 on the bottom surface and the side surface side of the main body 2, and air is taken in from the air inflow port 45, and the cooled air flows out from the discharge hole 46 provided in the upper surface.

Next, the heating coil will be described using FIG.

The heating coil unit 25 for heating the conditioning pot (not shown) is heated The coil 13, the coil base 24, and the ferrite iron (not shown) are comprised. The heating coil unit 25 is disposed below the panel 3 of each of the mounting portions 6, and is provided between the panel 3 and the heating coil 13 with a predetermined gap therebetween. This gap is for cooling the panel 3 and the heat-resistant paint surface and the heating coil applied to the panel 3 in order to pass the cooling air mentioned later. A right heating coil unit 25a is provided below the right mounting portion 6a, a left heating coil unit 25b is provided below the left mounting portion 6b, and a central heating coil unit 25c is provided below the central mounting portion 6c.

The coil of the heating coil 13 is an enameled wire for suppressing a skin effect. In order to heat the conditioning pot (not shown), the heating coil 13 applies a voltage of several tens of kHz and several hundreds V from the inverter 72 which will be described later.

The coil base 24 fixes the heating coil 13 from below, and ferrite iron (not shown) is embedded in the coil base 24.

When automatic conditioning or the like is performed, the temperature detection of the pan is performed by the temperature detecting element 21 provided in the heating coil 13. The temperature of the bottom of the pan is detected by the panel 3 to an indirect temperature. Further, in the drawing, the temperature detecting element 21 is provided in the right heating coil unit 25a and the left heating coil unit 25b. However, by providing the central heating coil unit 25c, it is possible to manage heat preservation or stewing using the heating coil. temperature. Further, the temperature detecting element 21 may use an infrared sensor in addition to the thermistor.

Next, an inverter for exciting the heating coil and its cooling will be described based on Fig. 4 .

Fig. 4 is a longitudinal sectional view of the heating conditioner main body 2, and a substrate on which an inverter is mounted and a cooling element for cooling are described in the lower central portion. Hot cooling fan. The left and right inverter drive board 18 on which the inverter for driving the left and right heating coils 13a and 13b is mounted is disposed at the lowermost portion, and the center inverter drive board 17 that drives the center heating coil 13c is disposed in the upper stage. In general, the upper section is easy to receive the heat of the lower section, but the maximum input of the central heating coil 13c is lower than that of the other coils, so the amount of heat generation is small. Therefore, the inverter drive substrate 17 that drives the central heating coil 13c is disposed in the upper stage. Moreover, as shown in FIG. 8, the electronic component for driving the right heating coil 13a and the left heating coil 13b is mounted on the inverter drive board 18, and the right inverter 72a, the left inverter 72b, and the right inverter control which will be described later are mounted. The means 73a and the left inverter control means 73b.

Returning to Fig. 4, the heat radiating fans 22 and 23 for effectively reducing the temperature of the electronic components by heat exchange between the heat generated in the electronic components and the cooling air are provided on the respective substrates, and the heat radiating fan 23 is smaller than the heat radiating fan 22.

As described above, the maximum heating power of each heating coil is set smaller than the right heating coil 13a and the left heating coil 13b, and the central heating coil 13c is set smaller. Therefore, the power consumption of the central inverter driving substrate 17 is higher than that of the left and right frequency converter. 18 small. Therefore, the heat generation amount of the electronic component is also less than that of the left and right inverter drive substrates, and the heat dissipation fan used for cooling is not too large. Therefore, the central inverter drive substrate 17 uses a smaller heat dissipation fan 23, and the left and right inverter drive substrates 18 use a larger heat dissipation fan 22.

Each of the heat-generating components is cooled by the air sent from the blower fan 20. The outside air for cooling sucked from the intake port 7 passes through the substrate outer casing 15 for accommodating the left and right inverter drive substrate 18, the central inverter drive substrate 17, and the control substrate 19, and sucks away the heat of the heat radiating fans 22, 23. It Thereafter, each heating coil is cooled and discharged from the exhaust port 8 to the outside.

The substrate outer case 15 shown in Fig. 3 is disposed below the heating coil unit 25 opposite to the heating coil unit in which the baking oven 4 is provided. This embodiment is disposed on the lower side of the right heating coil unit 25a. By accommodating the substrate in the substrate outer casing, the substrate is prevented from being affected by the radiant heat from the heating coil 13 or the baking furnace 4 during conditioning, and is formed in the substrate outer casing 15. There is an air passage through which the cooling air passes, so that the cooling air efficiently passes through the stacked substrate and the heating coil unit and the upper display portion.

Since all the circuits cannot be accommodated in the substrate outer case 15, the components that do not generate heat most, the parts that do not have a large current, the control circuit of the entire system that heats the conditioner, and the inverter circuit are mounted. The control board 19 of the control unit is disposed above the substrate outer case 15.

Next, the operation of the heating coil 13 will be described using FIG.

The operation of the heating coil 13 is performed by an electrostatic capacitance type or a mechanical upper operation portion 9 provided on the front panel 14a of the panel 3 or the near side. The right upper operation portion 9a, the upper center operation portion 9c, and the upper left operation portion 9b are disposed from the right side corresponding to the right placement portion 6a, the center placement portion 6c, and the left placement portion 6b on which the pot is placed. This is a configuration in which the operator can intuitively understand the relationship between the pan and the operation unit.

As is clear from the drawing, the right upper operation portion 9a and the upper left operation portion 9b form the same key arrangement. Therefore, the operation of the right heating coil 13a will be described below as a representative.

Symbol 48 is the key to the start or stop of conditioning, conditioning The LED lamp 53 will illuminate.

The conditioning firepower is selected by the fire button 49. It is divided into four levels of small fire, weak fire, medium fire, and big fire. In order to set the required firepower by one operation, buttons are provided individually. For each firepower standard, for example, a maximum of 12 levels of firepower adjustment can be made. The relationship between each firepower and power consumption is: "1" is equivalent to 100W, "2" is equivalent to 200W, and "3" is 300W. 4" grade 400W, "5" grade 500W, "6" grade 800W, "7" grade 1.1kW, "8" grade 1.4kW, "9" grade 1.6kW, "10" grade 2kW, "11" grade 2.5kW The "12" rating is 3kW. The numbers of the respective levels are numbers which are displayed as the standard of the firepower in the display unit 10 described later. In addition, the relationship between the firepower mark and the actual level display is divided into small fires of "1", weak fires of "2", "3", "4" and "5", and medium fires of "6", "7" and "8". The fires are "9" and "10", and the high power is "11" and "12". The fire button 49 can be directly set to the representative firepower of four levels of firepower. The small fire button 49a can be set to "1", the weak fire button 49b is "4", the middle fire button 49c is "7", and the fire button 49d is " The firepower of 10" will be illuminated by the LED light 54 located in the set button portion.

The symbol 51 is mainly a timing key to be selected when performing timing adjustment such as stewing or warming. Reference numeral 52 is a menu button for selecting automatic cooking, cooking, frying, boiled water, etc., and pressing the menu button 52 displays a menu on the upper display unit 10, which will be described later. Each time the menu button 52 is pressed, the displayed menu is displayed. It will switch to select the menu to use.

Moreover, the setting of the key 50 can be used to adjust the firepower or chronograph The setting of the time, the setting of the rice amount during cooking, the setting of the finished product adjustment for automatic conditioning, and the setting of the oil temperature when the fry is performed. The setting key 50 is composed of an UP key 50a and a reduced DOWN key 50b for increasing the number of settings, etc., and when the LED lamp 55 located in the setting key 50 is turned on, the setting key 50 is valid, and when the light is turned off, it is invalid.

For example, a case where the setting of the fire power by the setting key 50 will be described. First press the middle fire button 49c to set the firepower to "7". Next, the UP key 50a of the setting key 50 is pressed twice, and the number of the firepower displayed on the display unit 10, which will be described later, is changed from "7" to "8", and from "8" to "9", the fire is set to "fire". 9". The LED lamp 54 of the fire button 49 is also turned off by the LED lamp of the middle fire button 49c, and the LED lamp of the large fire button 49d is turned on. The other settings are also the same. For example, the operation of the setting key 50 after the chronograph key 51 is pressed becomes the time setting.

Next, the center upper operation unit 9c will be described. The main conditioning of the central loading portion 6c is heat preservation and stewing. The reason is as described above. Therefore, the heating power of the central heating coil 13c is also set to be smaller than the heating power of the other heating coils. Therefore, as long as there is a small fire, a weak fire, or a medium fire, it is enough to set the setting button 62 to the cycle button type because it is returned to the original position as long as it is pressed up to three times, so it is not like the two heating coils 25a on the near side. And 25b are provided with firepower setting keys corresponding to various firepowers. This ensures the setting space of the buttons. In addition, since the content of the automatic conditioning menu is a fire-limited design, it is only stewed, insulated, and the like.

Referring to FIGS. 2 and 7, the plurality of buttons arranged on the upper operation unit 9 are arranged side by side in the width direction of the main body 2 in the front frame 14a. Column. Further, the right upper operation portion 9a, the center upper operation portion 9c, and the left upper operation portion 9b are arranged in this order from the right side toward the main body 2. However, it is only that the buttons are arranged in a row in the horizontal direction, and the boundary is difficult for the user to discriminate. Therefore, it is necessary to perform some processing in which each of the upper operation portions is surrounded by a frame, re-enclosed by color, and the color of the keys is different. In the present embodiment, each of the upper operation portions is surrounded by a frame line, and at least 1.5 large spaces are partitioned between the right upper operation portion 9a and the center upper operation portion 9c, and between the upper center operation portion 9c and the left upper operation portion 9b. The interval above the button width. Thereby, it is easy for the operator to distinguish the visual and tactile effects of the classification of the operation buttons.

Next, a description will be given of a display reflecting the result of the foregoing operation. The content corresponding to the key operation of the upper operation unit 9 is displayed on the upper display unit 10. The displayed contents are the fire power display set by the upper operation unit 9, the time display for the time adjustment, the display of the set oil temperature for the fry, and the like. The upper display portion 10 is disposed on the near side of the panel 3 placed on the upper surface of the main body 2, and on the back side of the panel 3. Therefore, when the display is viewed through the panel 3, the display portion of the upper display portion 10 is processed in order to see the display content through the panel 3. Further, in order to make the set fire power easy to distinguish by the image, the backlight color of the display portion is set. In this embodiment, the small fire and the weak fire are displayed in green, the medium fire is displayed in orange, and the fire and high power are displayed in red.

In the above embodiment, the upper upper display portion 10a, the upper upper display portion 10c, and the upper left display portion 10b are divided into the upper upper display portion 9, and the upper display portions are arranged linearly along the front frame 14a, but The center upper display portion 10c may be disposed closer to the center mounting portion 6c than the right upper display portion 10a and the left upper display portion 10b.

Each of the upper operation unit 9 and the upper display unit 10 is provided on each of the mounting portions 6 on the panel 3, and is arranged such that when the line of sight is linearly moved from the respective placement units 6 to the near side, approximately corresponding to each of the straight lines The upper operation portion 9 and the upper display portion 10 of the placing portion 6 are present, and the upper operation portion 9 is disposed closer to the conditioner side than the upper display portion 10.

Next, an operation portion related to the baking oven 4 will be described. As shown in Fig. 1, a baking oven operation portion 12 to be described later for operating the baking furnace 4 and an operation panel 5 on which the baking oven display portion 65 is disposed are disposed on the right side of the baking oven 4. The operation panel 5 is located in front of the main body 2 to form a kangaroo type opening and closing mechanism. Fig. 1 shows a state in which the operation panel 5 is closed, and Fig. 2 shows a state in which the operation panel 5 is opened. At the time of conditioning, the operator can perform the operation of the baking oven operation unit 12 and the confirmation of the baking oven display unit 65 (Fig. 6) in a standing state.

According to Fig. 6, various keys will be described. Select the grilled fish and food mode (various automatic conditioning) through the grill selection menu button 66. Each time the grilling fish button 66a is pressed, the whole fish, the fish block, the dried fish, the grill, and the manual LED lamp are cyclically switched, and the illuminated menu is selected. Similarly, by pressing the food mode button 66b, the lighting status of the pizza, aluminum foil baking, and baking LEDs will be switched, and the lighting menu will be selected.

After selecting the menu, the conditioning product (cooking degree) can be set by the setting button 68. Each time the UP button 68a or DOWN button 68b is pressed, the baking oven is displayed. The weak ‧ medium and strong LED lights of the display unit 65 are illuminated, so that the selection can be made. Moreover, pressing the chronograph key 69 selects the conditioning time. At this time, the timing time (heating end time) can also be selected by the setting key 68. When the various settings are completed, the opening key 67 for starting, stopping, and canceling the adjustment of the selected menu is started, and the conditioning is started. Further, in the case where a timer is set, the conditioning can be stopped by pressing the switch key.

Next, management of power consumption for one of the roles of the control means 74 will be described based on Fig. 9.

This drawing is an outline flow chart in which the control means 74 manages to prevent the accumulated power consumption from exceeding the maximum power consumption of the product. When the operation unit ‧ indicates that the required heating power is changed, the control unit 74 confirms whether or not the accumulated power consumption (Ws) at the time of the change request exceeds the maximum power (Wmax) of the product, and does not exceed the maximum power, and instructs the operation ‧ display unit 75 The change of the firepower, the inverter control means 73 or the heater control means 82 indicate the start of the conditioning and the change of the heating power. On the contrary, if the condition is insufficient, the setting of the change is not accepted.

Step 91 is a process of monitoring the operation of the display unit 75 by the accumulation of the power consumption at the time and the operation of the display unit 75, and monitoring the cumulative fire power monitoring step after the power consumption change due to the additional request for the new conditioning or the current firepower change request. The sum (Ws) of the power consumption at the time when the firepower is changed is determined.

Step 92 is a step of comparing the sum of the power consumption (Ws) at the time of the heating power change request obtained in the thermal power monitoring step with the maximum power consumption (Wmax) of the product, and the result of the comparison is the cumulative power consumption (Ws) when the fire power is changed. When it is smaller than the maximum power consumption (Wmax), it moves to the heating power changing step 93 described later, and the other moves to the automatic conditioning confirmation step 94 which will be described later.

Step 93 is a firepower change step that allows the firepower change request to be made, and the firepower is changed according to the firepower change request.

Step 94 is to confirm that the setting of the conditioning in the left loading portion 6b is by manual The set conditioning is also the automatic conditioning confirmation step using the automatic adjustment of the automatic menu. The manual conditioning is moved to the automatic firepower changing step 95 described later. Since the automatic power conditioning cannot be changed during the automatic conditioning, the final determination is moved to the firepower change request. Reject step 96.

In step 95, since the conditioning in the left mounting portion 6b is manually controlled, the heating power on the left mounting portion 6b side is automatically adjusted, and the cumulative power consumption (Ws) when the heating power change request is requested does not exceed the maximum consumption of the product. Automatic firepower change procedure for electricity (Wmax). In this way, when the firepower is automatically changed, the notification is made to let the conditioner know the change notification sound or the display of the changed content.

Step 96 is a rejection step that does not recognize the change request of the firepower. In this case, a warning indicating that it is not accepted must also be issued.

This description is an example in which the priority of the maintenance of the heating power on the left mounting portion 6b side is set to be low. The priority of the heating power required for each mounting portion can be automatically changed by the combination used or the like. For example, when both the right mounting portion 6a and the left mounting portion 6b are heated, and then the baking is performed using the baking oven 4 or the central mounting portion 6c, it is assumed that the left mounting portion 6b is automatically conditioned. The priority on the side of the right placement portion 6a is set to be low.

Further, the center placing portion 6c is automatically conditioned (heat preservation, stewing), and is not related to manual operation, so the priority is lowered.

This embodiment is constructed by the above configuration, and the operation will be described next.

For example, assuming that the user has just started using the fire of a large fire, and then putting in a situation such as green vegetables and the like to stir-fried vegetables. Pot When the right loading portion 6a is placed and the fire button 49d of the fire of the upper right operating portion 9a is pressed, the pressed button signal is sent to the control means 74 as the input signal 80, and the control means 74 recognizes that the fire button 49d has been input. This content is transmitted as a display signal 79 to the operation display unit 75, and the LED lamp 54 as the heating key 49d of the display unit is turned on. Next, in the upper right display portion 10a, the number of "9" indicating the firepower of the fire is turned on, the backlight color is red, and the display is set to a large fire. Next, when the opening key 48 of the upper right operation portion 9a is pressed, the LED lamp 53 is turned on and the heating is started via the same transmission path (hereinafter, the description of the same signal path is omitted).

When the control means 74 instructs the start of the conditioning, the right power is set to "9" by the right control signal 78a, and the right inverter control means 73a receiving the message performs the control of the right inverter 72a. The power of the right heating coil 13a is controlled to form the set fire power. The right inverter 72a adds the detected value of the input voltage and the input current to the right detection signal 77a, and then transmits it to the right inverter control means 73a. The right inverter control means 73a obtains the power consumption from the detected value, and performs the right heating coil 13a. In the power control, the set fire power is determined to be "9" power consumption (the description of the same signal path is omitted below).

Further, when the control means 74 recognizes that the conditioning is to be started, the blower fan 20 is turned ON. When the blower fan 20 is turned on, the blower fan 20 sucks the air outside the main body 2 from the intake port 7, and the amount of air sent from the blower fan 20 is distributed to each of the heat generating components, and is discharged from the discharge port 8 while cooling the components.

The air sent from the blower fan 20 mainly passes through the left and right inverter drive boards 18, the center inverter drive board 17, the right heating coil unit 25a, the left heating coil unit 25b, and the center heating coil unit 25c in the substrate outer casing 15. The air cooled by the left and right inverter drive boards 18 and the central inverter drive board 17 is sent to the control board 19, the surface display unit 10, the upper operation unit 9, and the heating coil unit 25, and the heating coil unit 25 directly comes from the blower fan. The air of 20 is cooled together with the air that has passed through the substrate, and all of this air is discharged from the exhaust port 8. The blower fan 20 can be a multi-blade blower or a turbo blower.

Next, the pan is heated, and the ingredients are put into the temperature suitable for the input of the ingredients. Due to the input of the ingredients, the temperature of the pot is lowered and the conditioning can be carried out. At this time, in the case where the pan is heated, the supply of electric power to the right heating coil 13a is interrupted before the temperature of the bottom of the pan reaches about 300 ° C by the right temperature detecting element 21a provided in the right heating coil 13a. The reason is that the impact temperature of the non-crystallized glass used for the panel 3 is three hundred and ten ° C, and therefore, the panel 3 is prevented from being broken when the panel 3 is cooled by the rapid cooling of the ice.

The automatic conditioning of the electric power supplied to the heating coil is adjusted while detecting the temperature of the pan, the maximum temperature of the fry can be set to 200 ° C, and the maximum temperature of the pan during preheating can be set to 240 ° C. Thus, it must be used in the impact temperature of the amorphous glass used for the panel 3.

Thus, in the induction heating conditioner using the induction heating of the heating source of the heating pot, the non-crystallized glass can be used without being limited to the heating amount of the heating pot. Also, by using heat from the heater to heat the heater When heating is performed at about 600 ° C, for example, by using a heat radiation heater and induction heating, the heat radiant heater of the panel 3 using the non-crystallized glass may be used only in a portion heated to a temperature higher than the impact temperature. . For example, a portion heated to a temperature higher than the impact temperature of the panel 3 is formed into a circular opening, and a portion of the opening is sealed with a circularly crystallized glass having higher heat resistance.

Moreover, among the induction heating conditioners in which the heating unit is a single port, in many cases, a ceramic panel is used for the panel. In this case as well, in order to bring a sense of high quality, the above control method can be placed, and amorphous glass is used as the substrate of the panel.

The amorphous glass described in the present embodiment includes quartz glass, perrhenic acid glass, and barium borate glass, and particularly in the present embodiment, it contains about 80% of barium, about 10 to 15% of boric acid, and the thermal shock temperature is Barium borate glass of 300 ° C or more and 500 ° C or less.

According to the present embodiment described above, by using a transparent glass substrate having no deviation in hue between each batch, a heat-resistant coating can be applied from the inner side (bottom surface) of the glass substrate to exhibit a view from the surface side. The panel is felt to have the thickness of the glass, and there is no turbid and high-grade panel 3 in the color. Further, by applying heat-resistant coating to the inner surface (lower surface) of the glass substrate, even if an impact is applied to the glass substrate to break the glass, the scattering of the glass fragments can be avoided by the subsequent effect of the heat-resistant coating.

Moreover, the glass base material of the panel 3 can reduce cost compared with a crystallized glass and a ceramic panel.
