  In addition, a door 130 for opening and closing the heating chamber 300 provided in the housing 100 is provided in front of the housing 100 and below the operation unit 110. The door 130 is configured to be rotatable about the lower end side, and a handle portion 131 is provided at the upper end of the door 130 so that the user can easily open and close the door 130. Note that the door 130 may be made of heat-resistant glass so that the inside of the heating chamber 300 can be seen.

  An air supply port 140 is provided on the back side of the housing 100. The air supply port 140 is for supplying outside air into the housing 100. An exhaust port 150 is provided on the back side of the housing 100. The exhaust port 150 is for exhausting the air in the housing 100 to the outside. Details of the air supply port 140 and the exhaust port 150 will be described later.

  As shown in FIGS. 3 to 5, a motor chamber 200 configured in a box shape is provided in the upper portion of the housing 100. A duct 210 is provided in the motor chamber 200. The duct 210 is made of, for example, a resin material having high heat resistance. A motor 220 for rotating the cooling fan 230 and the circulation fan 660 is provided on the duct 210. As the motor 220, a scraping motor is used. However, the motor 220 is not limited to a scraping motor, and a motor other than the scraping motor, for example, a DC (Direct Current) fan motor may be used.

  As shown in FIG. 6, a first opening 211 for connecting the inside and the outside of the duct 210 is provided at the approximate center of the duct 210. For convenience of explanation, the upper surface of the housing 100 is omitted in FIG.

  An air supply port 140 is provided above the back surface of the housing 100 so as to communicate with the motor chamber 200. The air supply port 140 is made up of a large number of small-diameter holes and supplies the outside air into the motor chamber 200.

  An exhaust port 150 is provided below the air supply port 140 on the back surface of the housing 100 so as to communicate with the motor chamber 200. The exhaust port 150 is composed of a large number of small-diameter holes, and is used to exhaust the air in the motor chamber 200 to the outside.

  The motor 220 is provided so that the motor coil 221 is positioned on the air inlet 140 side. As a result, the air supplied from the air supply port 140 into the motor chamber 200 is surely in contact with the motor coil 221, so that the cooling efficiency of the motor coil 221 can be increased.

  Below the duct 210, a cooling fan 230 that is rotated by the power of the motor 220 is provided. The cooling fan 230 is attached to the rotating shaft of the motor 220. The cooling fan 230 takes in the outside air from the air supply port 140 into the motor chamber 200 and causes the air in the motor chamber 200 to flow so that the air in the motor chamber 200 is discharged from the exhaust port 150. The motor 220 is cooled by the flow of air by the cooling fan 230, and overheating of the motor 220 can be prevented. The overheating of the motor 220 may be due to the heat generated in the motor 220 itself, or the heat in the heating chamber 300 may be transmitted to the motor 220 through the shaft of the motor 220.

  The duct 210 is connected to the exhaust port 150. Air that flows into the motor chamber 200 from the air supply port 140 is sucked by the cooling fan 230 and flows into the duct 210 through the first opening 211. The air is then discharged from the exhaust port 150 through the duct 210.

  A substantially rectangular second opening 213 is formed on the exhaust port 150 side of the duct 210. The second opening 213 communicates with the exhaust port 150, and the air in the motor chamber 200 is exhausted from the exhaust port 150 through the second opening 213 of the duct 210. The diameter of the cooling fan 230 and the width of the second opening 213 may be substantially equal, or the width of the second opening 213 may be greater than the diameter of the cooling fan 230. Thereby, the air blown out toward the exhaust port 150 by the cooling fan 230 can be smoothly discharged from the exhaust port 150 through the second opening 213.

  The cooling fan 230 is provided at a position substantially the same height as the exhaust port 150. Thereby, since the air discharged by the rotation of the cooling fan 230 is discharged from the exhaust port 150 at the shortest distance without being obstructed by anything, the flow efficiency of air in the motor chamber 200 can be improved.

  As shown in FIG. 6, a notch 212 is provided at a position of the duct 210 substantially immediately below the motor coil 221 included in the motor 220. By providing the notch 212, air can easily flow from the outside to the inside of the duct 210 around the motor 220, particularly the motor coil 221. As a result, the flow rate of air around the motor coil 221 increases and the air flow becomes smooth, so that the cooling efficiency of the motor coil 221 can be increased.

  A circuit board 120 corresponding to the operation unit 110 including the cooking mode switch 111, the temperature setting dial 112, and the heating time setting dial 113 is provided in the motor chamber 200. Thereby, the circuit board 120 can also be cooled by causing air to flow in the motor chamber 200 by the cooling fan.

  Furthermore, the housing 100 is also cooled by causing the air in the motor chamber 200 to flow. Thereby, it can prevent that a user touches the housing | casing 100 and is burned during cooking. In addition, it is possible to prevent a situation in which an article cannot be placed on the housing 100.

  Inside the rectangular box-shaped casing 100 of the heating cooker 10, a heating chamber 300 configured in a hollow box shape with the front surface being an opening 310 is provided. The opening 310 is opened and closed by the door 130. The heating chamber 300 is a space defined by a ceiling wall 301, a bottom wall 302, a left side wall 303, a right side wall 304 and a back wall 305. The bottom wall 302 is made of a metal having excellent light reflectivity, such as an aluminum-plated steel plate or stainless steel, and functions as a reflector that reflects the heat of the oven heater. However, the metal which comprises the bottom wall 302 is not restricted to them, What kind of thing may be used if it is a metal material with good light reflectivity.

  As shown in FIGS. 3, 4, 5, and 7, a placement net 320 is provided below the heating chamber 300. In FIG. 7, for convenience of explanation, the ceiling wall 301, the left side wall 303, the right side wall 304, the back wall 305, the upper hood 610, and the lower hood 620 of the heating chamber 300 are omitted. The placement net 320 is a net made of a metal wire. A square dish 400 can be placed on the placing net 320.

  In addition, it is not restricted to the mounting net | network 320, By providing the left-right paired rail extended from the front of the heating chamber 300 to the back, and supporting the both ends of the square plate 400 with a rail, the square plate 400 floated from the bottom wall 302. You may make it hold | maintain in a state. The placement net 320 may be configured to move back and forth in conjunction with opening and closing of the door 130.

  As shown in FIGS. 3 and 7, the square plate 400 is formed into a bottomed rectangular box shape having an open top from a flat bottom surface portion 401 and a side surface portion 402 that rises in a curved shape from the outer periphery of the bottom surface portion 401. It is configured. Although described in detail later, the shape of the side surface portion 402 is to make it easier for hot air descending in the heating chamber 300 to be directed toward the center of the square dish 400. In addition, a flange 403 extending in the horizontal direction is formed on the entire peripheral edge of the square plate 400, and has a size for blocking the flow path of hot air below the flange 403 in the heating chamber 300. Yes. A breathable top plate member 410 is detachably provided on the opening side of the square plate 400.

  The top plate member 410 is configured as a net-like member having a size that fits the inner peripheral edge of the flange 403. The material to be cooked may be placed directly on the top surface of the top plate member 410. Since the top plate member 410 is configured in a net shape having a ventilation gap, the hot air blown down can pass through the top plate member 410 and enter the square plate 400. Thereby, it becomes possible to heat the to-be-cooked material mounted on the top plate member 410 from below with hot air. It is also possible to place the material to be cooked directly on the square plate 400.

  The square plate 400 may be integrally formed of a high heat-resistant resin such as glass reinforced PPS resin, glass reinforced PBT resin, polyimide resin, or the like, or may be formed of sheet metal to have a fluorine coat finish or enamel finish. Furthermore, you may manufacture with heat-resistant tempered glass, ceramics, etc.

  When hot-air circulating cooking is performed by the heating cooker 10, the square dish 400 provided with the top plate member 410 is placed on the placement net 320, and the material to be cooked is placed on the top plate member 410. Moreover, when performing oven cooking, a to-be-cooked material is directly mounted on the square plate 400 except for the top plate member 410. Further, when the cooking device 10 is used as an oven toaster, the material to be cooked is placed directly on the placing net 320. When the cooking device 10 is used as an oven toaster, an oven toaster dish different from the square dish 400 may be placed on the placement net 320.

  The space below the square plate 400 of the heating chamber 300 is closed by placing the square plate 400 on the placement net 320 during the hot-air circulating cooking that is the first cooking mode. The inside can be narrowed. As a result, hot air does not circulate in the entire area of the heating chamber 300, but hot air circulates in a space above the square plate 400, so that heating efficiency is increased and the temperature in the heating chamber 300 is likely to rise. Become. Thereby, shortening of heating time, reduction of power consumption, etc. can be aimed at.

  Two upper oven heaters are provided above the heating chamber 300 so as to extend between the left side wall 303 and the right side wall 304. Further, two lower oven heaters are provided below the heating chamber 300 so as to extend between the left side wall 303 and the right side wall 304. The configurations of the upper oven heater and the lower oven heater will be described later.

  Above the upper oven heater in the heating chamber 300, a fly heater 500 is provided. The frying heater 500 is a heater that operates in hot air circulation cooking, which is the first cooking mode. In the first cooking mode, the heating cooker 10 circulates the air heated by the frying heater 500 in the heating chamber 300 at high speed, thereby cooking fried food such as French fries and fried chicken without using oil. Mode. For example, the fly heater 500 can circulate hot air of about 80 to about 200 degrees in the heating chamber 300.

  The fly heater 500 is connected to the circuit board 120 and the power supply circuit. When performing hot air circulation cooking that is the first cooking mode, the user sets the cooking mode changeover switch 111 of the operation unit 110 to hot air circulation cooking. Further, the user designates the temperature necessary for cooking with the temperature setting dial 112 and designates the time necessary for cooking with the heating time setting dial 113. A control circuit on the circuit board 120 energizes the fly heater 500 to turn it on, and controls the temperature and heating time of the fly heater 500 in accordance with the content input from the user to the operation unit 110.

  As shown in FIG. 7, the fly heater 500 is configured as a spiral sheathed heater distributed in a plane and having a ventilation gap. The spiral sheathed heater has an advantage that a high heat capacity can be obtained because it has a ventilation gap and does not block the flow of hot air and has a large surface area. In addition, the sheathed heater has an advantage that it emits much far infrared rays, although its rise as a heat source is inferior to that of a quartz tube heater.

  A circular dish-shaped upper hood 610 and a lower hood 620 are provided above the fly heater 500 and below the duct 210. The upper hood 610 and the lower hood 620 have curved side surfaces and are provided so as to open downward. The upper hood 610 and the lower hood 620 are made of metal such as an aluminized steel plate.

  A space between the upper hood 610 and the lower hood 620 functions as an air flow path 630 that is a flow path for hot air. A suction port 640 for sucking hot air in the heating chamber 300 into the air flow path 630 is provided in the approximate center of the lower hood 620. Further, the outer edge portion of the air flow path 630 functions as a blowout port 650 that blows hot air into the heating chamber 300. The outlet 650 is configured in an annular shape. Further, a circulation fan 660 is provided in the air flow path 630 substantially in parallel with the fly heater 500. Circulation fan 660 is attached to the rotating shaft of motor 220.

  Due to the rotation of the circulation fan 660 by the power of the motor 220, the air in the heating chamber 300 is sucked up to the circulation fan 660 side. At that time, the air is heated by the fly heater 500 by passing through the ventilation gap of the fly heater 500. The air heated by the fly heater 500 is sucked into the air flow path 630 from the suction port 640 of the lower hood 620 (arrow A in FIG. 3). The air sucked into the air flow path 630 is blown into the heating chamber 300 as hot air from the blowout port 650 at the outer edge of the air flow path 630 in the centrifugal direction by the rotation of the circulation fan 660 (FIG. 3). Arrow B).

  The hot air blown out from the outlet 650 by the circulation fan 660 descends in the heating chamber 300 (arrow C in FIG. 3), and along the side surface portion 402 of the curved square plate 400, the bottom surface of the square plate 400. In the space between the portion 401 and the top plate member 410, it flows toward the center of the square plate 400. When hot air enters the square plate 400, the cooking material placed on the top plate member 410 can be heated from below.

  The hot air is sucked upward in the square plate 400 by the circulation fan 660 (arrow D in FIG. 3), heated again by the fly heater 500, and sucked into the air flow path 630 from the suction port 640 (arrow A). ). When the heating cooker 10 operates in the first cooking mode, this circulation of hot air (arrows A to D in FIG. 3) is continuously repeated.

  Since the circulation fan 660 rotates, the hot air can be circulated efficiently by configuring the fly heater 500 in a circular shape and the blowout port 650 in an annular shape.

  Further, since the hot air is blown out almost directly from the blowout port 650, the hot air can be circulated efficiently by positioning the side surface portion 402 of the square plate 400 at a position almost directly below the blowout port 650.

  A hood cover 670 is provided on the upper hood 610 with a slight gap. The hood cover 670 is formed in a shape substantially the same as the upper hood 610. The hood cover 670 is made of a heat insulating material such as a stainless steel plate. The hood cover 670 functions as a partition member for preventing heat from the heating chamber 300 from being transmitted to the motor chamber 200. By providing a hood cover 670 with a gap between it and the upper hood 610, the heat insulation effect is further enhanced.

  Two upper oven heaters are provided above the heating chamber 300 so as to extend between the left side wall 303 and the right side wall 304. The upper oven heater located on the opening 310 side of the heating chamber 300 is referred to as a first upper oven heater 711, and the upper oven heater located on the back wall 305 side is referred to as a second upper oven heater 712.

  Further, two lower oven heaters are provided between the left side wall 303 and the right side wall 304 so as to be positioned below the heating chamber 300 and below the square plate 400. The lower oven heater located on the opening 310 side of the heating chamber 300 is referred to as a first lower oven heater 721, and the lower oven heater located on the back wall 305 side of the housing 100 is referred to as a second lower oven heater 722. Called.

  The oven heater is a heater that operates in the second cooking mode and generates radiant heat when energized. In the second cooking mode, the cooking device 10 functions as a so-called oven that heats the material to be cooked by the heat of the heater.

  The oven heater is connected to the circuit board 120 and the power supply circuit. When performing the oven cooking that is the second cooking mode, the user sets the cooking mode switching switch 111 of the operation unit 110 to the oven cooking. Further, the user designates the temperature necessary for cooking with the temperature setting dial 112 and designates the time necessary for cooking with the heating time setting dial 113. The control circuit on the circuit board 120 energizes the oven heater to turn it on according to the input content from the user to the operation unit 110, and controls the temperature and heating time of the oven heater.

  The heater for the upper oven and the heater for the lower oven are composed of, for example, a quartz tube heater. The quartz tube heater emits far infrared rays, but the amount generated is inferior to that of the sheathed heater. However, since it quickly rises as a heat source, it is suitable as a heat source for an oven. In addition, the number of the heaters for upper ovens and the heaters for lower ovens is an illustration to the last, and the number is not limited to two each.

  A reflector 800 is provided on each of the first upper oven heater 711 and the second upper oven heater 712. The reflection plate 800 allows the cooking material placed on the square dish 400 to be efficiently heated by reflecting the heat of the upper oven heater downward. Further, a roof portion 810 is provided on the reflection plate 800. The roof portion 810 is for smoothly flowing downward without blocking the hot air blown down into the heating chamber 300 from the upper outlet 650. This is because in hot air circulation cooking, it is necessary to circulate hot air at a high speed.

  One temperature detection unit 900 is provided in the heating chamber 300. The temperature detection unit 900 is for detecting the temperature in the heating chamber 300. The temperature detection unit 900 is configured using, for example, a liquid expansion thermostat. However, the temperature detection unit 900 is not limited to the liquid expansion thermostat, and other methods, for example, a temperature sensor using a thermistor may be used.

<2. Other embodiments>
A cooking device 20 according to another embodiment of the present invention will be described with reference to FIG. In another embodiment, the door 130 that is opened and closed for putting in and out the material to be cooked includes a door frame 130A and a door glass 130B made of heat-resistant glass. The inside of the heating chamber 300 can be seen through the door glass 130B. An open / close detection switch 1000 is provided at a part of the door frame 130A, for example, at the upper right corner portion. The open / close detection switch 1000 is constituted by, for example, a micro switch.

  The opening / closing detection switch 1000 is turned on / off in conjunction with opening / closing the door 130. An on / off signal of the open / close detection switch 1000 is supplied to the control unit. If the door 130 is inadvertently opened during cooking in the hot-air circulating cooking mode, the opening / closing detection switch 1000 detects that the door 130 has been opened, and the control unit stops the circulation fan 660 and energizes the fly heater 500. The control action that cuts off is performed.

  This is to prevent hot air from blowing out from the heating chamber 300 toward the user when the door 130 is opened carelessly. For example, in the case of fried food cooking using bread crumbs, hot air containing bread crumbs or oil may blow out from the opening 310.

  The open / close detection switch 1000 operates similarly in the oven cooking mode. In the oven cooking mode, when the door 130 is opened during cooking, all the heaters 711, 712, 721, 722 installed above and below are turned off by the control unit. In this way, safety measures are taken against the case where the door 130 is inadvertently opened.
