A mounting table 7 is installed. The mounting table 7 is made of ceramic with low dielectric loss. As means for heating the inside of the heating chamber 2, microwave heating means using microwaves, radiation heating means using heaters, steam heating means using steam, hot air circulation heating means using convection fans, Is provided.

  In the microwave heating, as shown in FIG. 3, the microwave is excited by the magnetron 22 installed at the lower part of the main body, propagates through the waveguide 21, and is heated through the rotating antenna 23 arranged at the lower part of the mounting table 7. It refers to a system in which the object to be heated 3 is radiated to the inside and heated by microwaves.

  Radiation heating means heating the object to be heated 3 by raising the inside of the heating chamber 2 by radiant heating using, for example, a sheathed heater or a mica heater installed at the lower part of the mounting table 7, the upper part of the heating chamber 2, or the side part of the heating chamber 2. It points to the method to do. Here, as shown in FIG. 3, an upper heater 25 and a lower heater 24 are arranged, and a heat insulating material 26 is installed above the upper heater 25.

  In the steam heating, water loaded in a tank 40 (FIG. 8) installed in the lower part of the main body is sucked into the boiler 28 and heated by the boiler 28, and is heated as superheated steam into the heating chamber 2 from the steam outlet 39. It refers to a method of spraying and heating the article 3 to be heated.

  The hot air circulation heating refers to a heating method in which high-temperature hot air is applied to the object to be heated 3 placed in the heating chamber using the convection fan 27 to accelerate the temperature increase of the object to be heated 3 and to reduce heating unevenness. . Here, as shown in FIG. 3, the air in the heating chamber is sucked by the convection fan 27 installed on the back surface of the heating chamber, the air is heated by a convection heater (not shown) attached around the convection fan 27, and the circulation provided at the upper portion of the back surface of the heating chamber. Hot air is circulated from the air blowing port 8 and the circulating air blowing port 9 provided at the lower back of the heating chamber so that hot air circulates.

  Usually, the microwave oven is provided with a square plate 6 as an accessory so that a large amount of the object to be heated 3 can be cooked at once or the cooking speed can be improved. The square plate 6 is configured to be installed in the heating chamber 2 by holding both side edges by a plurality of square plate holding units 17 provided in the heating chamber 2. Depending on the number of 6, the inside of the heating chamber 2 is defined as two or three in the vertical direction, and the object to be heated 3 is placed on the square plate 6 for cooking. As a material of the square plate 6, enamel or ceramic is generally employed. In particular, the hollow plate 6 made of enamel material has high conductivity and has a characteristic of reflecting microwaves when microwave heating is performed.

  In the present embodiment, the accessory storage portion that is stored when the square pan 6 is not used, that is, the square pan storage portion 10 utilizes the heat insulating space at the top of the main body, that is, the upper surface of the heating chamber 2 and the outermost main body facing the main body. Between. The square dish storage unit 10 has an opening on the front surface, and a square dish storage chamber door 12 for preventing entry of dust, dust, and the like is provided in the opening, and the square dish 6 can be taken in and out horizontally from the front of the main body. It is like that. Further, a pop-up type square pan pushing mechanism using a spring 33 (FIG. 6), which will be described later, is provided at the back of the square pan storage portion 10 so that the user can take out the square pan 6 without stress. Yes.

  Furthermore, the square dish storage unit 10 is provided with a cooling device. The cooling device includes a plurality of slits 37 formed on the front surface of the main body and a suction port 37 formed of a plurality of slits formed by punching in the upper part of the back surface of the main body in one side portion of the square dish storage portion 10 as shown in FIGS. A cooling fan 20 that generates a flow of air that sucks external air from the air inlet 14 through the slit, sucks outside air from the air inlet 37, passes through the heat insulating space, that is, the square dish storage portion 10, and exhausts from the air outlet 14, and the air inlet 37. The outside air sucked in further passes through the corner plate storage section 10 and turns back to form a labyrinth air passage toward the exhaust port 14. It is comprised from the partition plate 19 which partitions off. Here, as the cooling fan 20, for example, an axial fan or a sirocco fan can be employed. Needless to say, the mounting location of the cooling fan 20 and the positions where the air inlet 37 and the air outlet 14 are formed are not limited to one side of the square dish storage unit 10.

  Therefore, while the cooling air (external air) blown by the cooling fan 20 flows through the air path provided by the partition plate 19 in the square dish storage part 10, the internal atmospheric temperature of the square dish storage part 10 is lowered, The upper surface of the heating chamber that forms the heat insulating space of the main body 1 and the outermost surface of the main body facing the heating chamber are cooled and exhausted from the exhaust port 14 on the front surface of the main body. The exhaust temperature discharged is below a certain temperature that does not pose a risk of burns to the user. For this reason, even during radiant heating cooking using a heater, the upper surface of the main body 1 can be kept below a certain temperature, the volume of the heat insulating space, that is, the vertical dimension can be compressed, and the cooker main body can be downsized. Can be planned. Furthermore, since the heat insulation space is configured as the square dish storage unit 10, the heat insulation space can be used effectively, and the vertical dimension of the heat insulation space part can be reduced, and the convenience of accommodating accessories such as a square plate can be improved. Can be secured. In addition, it is possible to place a kitchen product with heat resistance above a certain temperature on the upper part of the main body even during radiant heating cooking using a heater, improving usability and risk of being damaged by burns etc. Can be avoided and safety is improved.

  In addition, in steam cooking using steam, it is desirable that the amount of steam discharged from the heating chamber 2 is large and this can be condensed and recovered as condensed water. This can be realized by providing a collecting device for condensing and collecting the steam in the square dish storage unit 10 through which the cooling air passes, and guiding the steam to the square dish storage unit 10.

  This will be described in more detail with reference to FIGS. That is, the steam outlet 44 for discharging the steam in the heating chamber 2 is installed near the blower opening of the cooling fan 20 at the bottom of the square dish storage section 10 as shown in FIG. The vapor is quickly condensed by forced cooling by the cooling fan 20. However, with this alone, steam discharged into the square dish storage unit 10 may be cooled in the entire area of the square dish storage unit 10 to cause condensation. Therefore, the steam condenser 43 provided with metal fins having a high heat transfer coefficient such as aluminum is provided on the inner surface of the square dish storage chamber door 12 so as to be inclined downward toward the inside as shown in FIG. Furthermore, the square dish storage part dew receiving 15 which receives condensed water under the vapor | steam condenser 43 is installed so that removal is possible.

  As a result, the cooling air cools the steam condenser 43, condenses the steam, and allows the condensed water to flow down to the square dish storage section dew receptacle 15 disposed at the lower part of the square dish storage section 10 to be collected. Moreover, since the square tray storage part dew stand 15 installed in the lower part of the square dish storage part 10 is removable, it can be removed and wash | cleaned. In this case as well, the temperature of the upper part of the main body can be lowered to a temperature at which the risk of being damaged such as a burn can be avoided by the cooling air passing through the heat insulating space, that is, the square dish storage unit 10, and safety is improved. Can be secured.

  As shown in FIGS. 6 and 7, the square plate pushing mechanism is arranged at the back of the square plate storage portion 10 and urges the square plate pushing plate 32 in the direction of pushing out the square plate 6. A rotating rod 29 that is rotatably attached to the shaft 30 and has a locking portion 31 that can be engaged with the square plate extrusion plate 32 at one end across the shaft 30, and the shaft 30 of the rotating rod 29. The other side of the square plate is installed so that one end thereof can come into contact with the other end, and the other end is connected to the linearly moving rod 38 extending in the front surface direction of the square dish storage unit 10, and the spring 33, that is, the square plate extrusion plate 32 and the locking part 31. The linear motion bar 38 is connected to the back so that the joint state can be released from the outside, and the accessory retrieval button, that is, the square dish ejection button 13 disposed on the front surface of the square dish storage unit 10, The linear motion rod 38 is arranged on one end side and linearly moves in the depth direction of the square dish storage unit 10. A pair of guides 45a and an angle so that the rotation rod 29 rotates between an angle at which the locking portion 31 can be engaged with the square plate extrusion plate 32 and an angle at which the engagement can be released. A pair of stoppers 45b to be regulated and a return spring (not shown) that constantly urges the rotating rod 29 in a direction (counterclockwise direction) in which the engaging portion 31 engages with the square plate pushing plate 32. The elastic force of the return spring is set to be larger than the elastic force of the spring 33. Moreover, the latching | locking part 31 is formed in the arrow shape which a front-end | tip reduces in diameter.

  Therefore, when the square plate 6 is stored, the square plate push-out plate 32 is pushed in by the square plate 6 so that the engaging portion 31 and the square plate push-out plate 32 are engaged (the upper stage in FIG. 7), and the repulsive force of the spring 33 is applied. keeping. Further, by pushing the square dish take-out button 13 provided on the front surface of the main body and pushing in the direct acting rod 38, the turning rod 29 is turned clockwise to release the engagement between the spring 33 and the locking portion 31. Then, a repulsive force for pushing out the square plate 6 is generated, and the square plate 6 can be pushed out by the square plate pushing plate 32.

  By the way, normally, a square plate gripping portion is provided at both side edges of the square plate 6 so as to be convenient for the user. However, as shown in FIGS. By providing the guide rail 16 along the inside of the square dish storage portion 10 and further providing the roller 18 on the guide rail 16, the square dish 6 can be taken in and out with a smaller force. For this reason, a spring having a small resilience can be used as the spring 33 for taking out the square dish, and the square dish 6 can be taken in and out without stress.

  The square plate pushing mechanism is not limited to the link mechanism, and for example, a gear mechanism can be adopted. Further, a mechanism for holding the repulsive force of the spring 33 is provided on the front side in the square plate storage unit 10. It may be arranged.

  Moreover, the heating cooker of this embodiment branches the vapor | steam which generate | occur | produced in the boiler 28 of a vapor | steam heating means from the path | route which injects into the heating chamber 2 from the vapor | steam ejection port 39a like FIG. A three-way valve for selectively switching the steam path between the heating chamber 2 side and the side dish storage unit 10 side is provided at the branch point of the steam path at the branch point of the steam path 39b installed in (Not shown). When the operation mode is switched to the accessory cleaning / sterilization mode by key operation on an operation panel (not shown) provided on the front surface of the main body 1, the steam flow path is switched to the square dish storage unit 10 side by the three-way valve. Then, the steam is spouted toward the square plate 6 stored with the surface on which the food is placed in the square plate storage unit 10 facing downward, and dirt such as oil and food adhering to the surface of the square plate 6 is lifted up. It is designed to be cleaned and sterilized. In addition, when there is no square dish 6 in the square dish storage part 10, a square dish steam washing function does not work. Whether or not the square dish 6 is stored can be easily grasped by weight detection means (not shown) provided in the square dish storage chamber 11.

  Also during this square dish steam cleaning, the cooling air cools the steam condenser 43 (FIG. 5), condenses the steam, and collects the condensed water by flowing down to the square dish storage section dew tray 15 provided at the lower part of the storage section. can do. Moreover, since the square tray storage part dew stand 15 installed in the lower part of the square dish storage part 10 can be removed as described above, dirt such as oil and dust that has been removed and cleaned by steam cleaning can be easily cleaned. can do. In this case as well, the temperature of the upper part of the main body can be lowered to a temperature at which the risk of being damaged such as a burn can be avoided by the cooling air passing through the heat insulating space, that is, the square dish storage unit 10, and safety is improved. Can be secured.

  Moreover, the cooking device of this embodiment is provided with the ultraviolet light LED 35 that generates ultraviolet light for sterilizing and disinfecting the stored plate 6 as shown in FIGS. 9 to 11. . The ultraviolet light LED 35 is disposed at a position where the entire food placing surface of the square dish 6 can be irradiated with ultraviolet rays when the square dish 6 is accommodated. In addition, as the wavelength of ultraviolet rays, deep ultraviolet light in the 230 nm to 350 nm band, which is considered to have high sterilization performance, is used. The operation of ultraviolet irradiation is automatically performed for a certain period of time after the operation is completed, or an operation key is provided on the operation unit, and irradiation is performed for a certain period of time when there is a key operation. In addition, it is desirable to arrange and irradiate a plurality of ultraviolet LEDs 35 at different angles as shown in FIG. 10 so that ultraviolet rays are evenly applied to the square plate 6. Of course, the ultraviolet LEDs 35 may be used alone. The purpose of the period can be achieved.

  In addition, in the case where the ultraviolet light LED 35 is disposed in the square dish storage unit 10, it is preferable to apply titanium oxide to the entire upper wall or inner wall of the square dish storage unit 10. Thereby, when the square dish 6 is not accommodated in the square dish storage part 10, the ultraviolet LED 35 is caused to emit light by a signal from the operation panel, and ultraviolet light is irradiated to the entire upper wall or inner wall of the square dish storage part 10. Thus, it is possible to cause photocatalytic action on titanium oxide and to decompose organic matter with the generated active oxygen to perform deodorization and sterilization.

  In addition, the photocatalytic action has super hydrophilicity, and has an effect of keeping water away from the surface when not exposed to ultraviolet rays. Due to the superhydrophilicity, the vapor discharged from the heating chamber 2 has a corner. Even when it becomes condensed water in the dish storage part 10, it flows down to the square dish storage part dew receptacle 15 without remaining on the surface, and the hygiene aspect can be maintained and improved. In addition, you may give a titanium oxide process to the square plate 6 itself. In this case, since the square dish 6 itself can have a sterilization function, the sanitary aspect can be further improved.

Embodiment 2. FIG.
FIG. 12 is a perspective view showing the appearance of the heating cooker according to the second embodiment of the present invention with the door opened, and FIG. 13 is an enlarged view of a main part showing the state of the square pan pushing mechanism when the square pan is housed, FIG. 14 is a front view including the partially transmissive display, and the same reference numerals are given to the same parts as those in the first embodiment.

  As shown in FIG. 12, the cooking device of the present embodiment has an accessory storage section for storing an accessory, for example, a square plate 6 when not in use, between the left side surface of the heating chamber 2 and the outermost surface of the main body facing the heating chamber 2. That is, the difference is from the first embodiment in that a square dish storage unit 10 is provided and the square dish 6 is stored in a horizontal orientation when used, and a vertical orientation when stored. Forced cooling function of the heat insulation space, that is, the external air is sucked by the cooling fan, and the flow of the air passing through the heat insulation space at the top of the main body and exhausting from the exhaust port is generated, so that the upper surface of the main body is kept below a certain temperature. The volume of the heat insulating space, that is, the vertical dimension can be compressed, and the configuration of the square plate extrusion mechanism is basically the same as that of the first embodiment.

  In this embodiment, the width of the square dish storage chamber 11 in the square dish storage unit 10 is set to a width that does not cause the posture of the square dish 6 so that the contact resistance is reduced as much as possible. The contact area with the chamber 11 is reduced. For example, the wall of the square dish storage chamber 11 is a wall provided with a partition in which several heat-resistant strings are stretched. Since the square plate 6 has a shape in which only the gripping portion is convex when viewed from the horizontal direction as shown in FIGS. 1 and 3, when the square plate 6 is made vertical, the guide provided at the bottom of the square plate storage chamber 11 is provided. It can be inserted into the rail 16 and can be stored smoothly. Moreover, since the roller 18 is provided in the guide rail 16, the square plate 6 can be taken in and out with a smaller force. For this reason, a spring having a small resilience can be used as the spring 33 for taking out the square dish, and the square dish 6 can be taken in and out without stress.

  Therefore, when the square plate 6 is pushed into the square plate storage unit 10, the square plate extrusion plate 32 is pushed in by the square plate 6, and the rear end edge of the square plate extrusion plate 32 comes into contact with the inclined surface of the locking portion 31 ( The upper part of FIG. When further pushed in, the locking portion 31 is lifted against the elastic force of the return spring (not shown) (the rotating rod 29 rotates in the clockwise direction), and when it gets over the square plate pushing plate 32, the elastic force of the return spring is obtained. As a result, the rotating rod 29 is rotated in the counterclockwise direction, whereby the rear end edge of the locking portion 31 and the front end edge of the square plate pushing plate 32 are engaged (lower stage in FIG. 13), and in this state, the return spring The repulsive force of the spring 33 is held by the elastic force. Further, by pushing the square dish take-out button 13 provided on the front surface of the main body and pushing in the direct acting rod 38, the turning rod 29 is turned clockwise to release the engagement between the spring 33 and the locking portion 31. Then, a repulsive force for pushing out the square plate 6 is generated, and the square plate 6 can be pushed out by the square plate pushing plate 32.

  Also here, as shown in FIG. 14, the steam generated in the boiler 28 of the steam heating means is branched from the path for ejecting the steam from the steam outlet 39a to the heating chamber 2, and the cleaning steam installed in the square dish storage unit 10 is used. A path leading to the jet port 39c is provided, and a three-way valve (not shown) for selectively switching the steam path between the heating chamber 2 side and the side dish storage unit 10 side is provided at a branch point of these steam paths. ing. When the operation mode is switched to the accessory cleaning / sterilization mode by key operation on an operation panel (not shown) provided on the front surface of the main body 1, the steam flow path is switched to the square dish storage unit 10 side by the three-way valve. Then, steam is blown out toward the square plate 6 stored with the surface on which the food is placed in the square plate storage unit 10 facing inward (rightward), and dirt such as oil or food adhering to the surface of the square plate 6 It is designed to float and clean and sterilize. Dirt such as oil and dust cleaned by steam cleaning flows down directly to the dew tray 41 installed at the bottom of the main body. In addition, when there is no square dish 6 in the square dish storage part 10, a square dish steam washing function does not work. Whether or not the square dish 6 is stored can be easily grasped by weight detection means (not shown) provided in the square dish storage chamber 11.

  Also in this embodiment, the ultraviolet LED 35 may be installed on the side surface of the square dish storage unit 10, and titanium oxide may be applied to the entire side wall or inner wall of the square dish storage unit 10, thereby eliminating the bacteria.・ Deodorizing effect can be obtained and hygiene can be improved.

  Moreover, the use frequency of the boiler 28 increases by implementing a square dish steam cleaning function. As a result, it is expected that the equipment life of the boiler 28 will be shortened. Therefore, it is preferable to add a notification function for informing the equipment life before failure or malfunction occurs. This notification function divides the content used by the boiler 28 into the number of times used during cooking and the number of times used in cleaning, and weights the number of times each operation is performed according to the difference in steam generation time. If the value is converted and recorded and exceeds a predetermined value, a message that informs the purchaser or manufacturer that the display unit is inspected, or that the equipment life is approaching Is a function to display.

That is, usage status detection means for converting the number of times or usage time of the boiler 28, which is steam heating means , from the number of menus using the boiler 28 executed by a signal from the operation panel, and the usage status detection means. And a device life determining means for notifying that the device life is near by a notifying means provided on the operation panel when the number of conversions or the conversion time stored in the table exceeds a preset guaranteed number of times or guaranteed time. As a result, a sudden boiler failure can be prevented.
