The other end of the steam supply passage 23 extends downward along both side surfaces of the heating chamber 20 and is connected to side surface steam outlets 22 provided on both side surfaces and the lower side of the heating chamber 20.

  The control device 80 includes a blower fan 28, a first steam heater 52, a second steam heater 53, a damper 68, a drain valve 70, a steam generator heater 42, and an operation panel 11 (see FIG. 1). A water tank water level sensor 36, a water level sensor 43, a temperature sensor (not shown) for detecting the temperature in the heating chamber 20 (shown in FIG. 3), and the humidity in the heating chamber 20 are detected. A humidity sensor (not shown) and a pump 35 are connected.

  The control device 80 includes a microcomputer, an input / output circuit, and the like, and based on detection signals from the water tank water level sensor 36, the water level sensor 43, the temperature sensor, and the humidity sensor, the blower fan 28, the first steam heater 52, and the like. The second steam heater 53, the damper 68, the drain valve 70, the steam generating heater 42, the operation panel 11 and the pump 35 are controlled according to a predetermined program.

  In the steam cooker 1 configured as described above, a power switch (not shown) in the operation panel 11 is pressed to turn on the power, and the operation of the operation panel 11 starts the cooking operation. Then, the control device 80 first starts the operation of the pump 35 with the drain valve 70 closed and the exhaust passage 67 closed by the damper 68. Water is supplied into the pot 41 of the steam generator 40 from the water tank 30 through the first to fourth water supply pipes 31 to 34 by the pump 35. And if the water level sensor 43 detects that the water level in the said pot 41 reached the predetermined water level, the pump 35 will be stopped and water supply will be stopped.

  Next, the steam generating heater 42 is energized, and a predetermined amount of water accumulated in the pot 41 is heated by the steam generating heater 42.

  Next, simultaneously with the energization of the steam generating heater 42 or when the temperature of the water in the pot 41 reaches a predetermined temperature, the blower fan 28 is turned on and the first steam heating heater 52 of the steam heating device 50 is energized. To do. Then, the blower fan 28 sucks air (including steam) in the heating chamber 20 from the suction port 25 and sends out air (including steam) to the circulation path 60. Since a centrifugal fan is used as the blower fan 28, a higher pressure can be generated compared to the propeller fan. Furthermore, by rotating the centrifugal fan used for the blower fan 28 at a high speed with a DC motor, the flow velocity of the circulating airflow can be extremely increased.

  Next, when the water in the pot 41 of the steam generator 40 boils, saturated steam is generated, and the generated saturated steam joins the circulating airflow passing through the circulation path 60 at the steam suction ejector 44. The steam discharged from the steam suction ejector 44 flows into the steam temperature raising device 50 through the second pipe 63 at a high speed.

  And the steam which flowed into the said steam temperature rising apparatus 50 is heated by the 1st steam heating heater 52, and turns into a superheated steam of about 300 degreeC (it changes with cooking contents). A part of the superheated steam is ejected downward from the plurality of ceiling steam outlets 55 provided in the lower ceiling panel 54 in the heating chamber 20. Further, another part of the superheated steam is ejected from the side surface steam outlets 22 on both side surfaces of the heating chamber 20 through the steam supply passages 23 provided on both the left and right sides of the steam heating device 50.

  Thereby, the superheated steam ejected from the ceiling side of the heating chamber 20 is vigorously supplied toward the heated object 90 in the center, and the superheated steam ejected from the left and right side surfaces of the heating chamber 20 Then, the product is supplied while being lifted so as to wrap the heated object 90 from below the heated object 90. As a result, convection occurs in the heating chamber 20 in such a manner that it is blown down at the center and rises outside the center. Then, the convection steam is sequentially sucked into the suction port 25 and repeats circulation such that it returns to the heating chamber 20 through the circulation path 60 again.

  By forming convection of superheated steam in the heating chamber 20 in this way, the superheated steam from the steam heating device 50 is sent to the ceiling steam outlet while maintaining the temperature and humidity distribution in the heating chamber 20 uniform. 55 and the side air outlet 22, and can efficiently collide with the heated object 90 placed on the rack 24. Then, the object to be heated 90 is heated by the collision of superheated steam. At this time, the superheated steam in contact with the surface of the object to be heated 90 also heats the object to be heated 90 by releasing latent heat when dew condensation occurs on the surface of the object to be heated 90. As a result, a large amount of heat of the superheated steam can be uniformly and quickly applied to the entire surface of the article 90 to be heated. Therefore, it is possible to realize cooking with no unevenness and good finish.

  Further, in the above cooking operation, when time elapses, the amount of steam in the heating chamber 20 increases, and the surplus amount of steam passes from the discharge port 27 through the discharge passage 64 and the exhaust duct 65. And discharged from the exhaust port 66 to the outside. At this time, the steam 69 passing through the discharge passage 64 is cooled and condensed by the radiator 69 provided in the discharge passage 64, thereby preventing the steam from being discharged to the outside as it is. The water condensed in the discharge passage 64 by the radiator 69 flows down in the discharge passage 64 and is guided to the receiving tray 21, and is processed together with the water generated by cooking after the cooking.

  After the cooking is finished, the control device 80 displays a cooking end message on the operation panel 11 and further sounds a signal by a buzzer (not shown) provided on the operation panel 11. Thereby, when the user who knows the end of cooking opens the door 12, the control device 80 detects that the door 12 has been opened by a sensor (not shown), and instantly opens the damper 68 of the exhaust passage 67. . Thereby, the first pipe 61 of the circulation path 60 communicates with the exhaust duct 65 through the exhaust passage 67, and the steam in the heating chamber 20 is blown by the blower fan 28 through the suction port 25, the first pipe 61, the exhaust passage 67 and The gas is discharged from the exhaust port 66 through the exhaust duct 65. This damper operation is the same even if the user opens the door 12 during cooking. Therefore, the user can safely remove the object to be heated 90 from the heating chamber 20 without being exposed to steam.

  FIG. 4 shows a cross-sectional view of the main part of the door 12 of the steam cooker. In FIG. 4, the lower side is the front side and the upper side is the back side (main body side). As shown in FIG. 4, a door panel 111 for holding the window 14 is attached to the back side of a door frame 112 that is a frame outside the door 12. A door cover 113 having a first recess 103 formed on the back side and the right side of the door frame 112 is attached. An outer heat resistant glass 114 is fitted on the door frame 112 side, and an inner heat resistant glass 115 is fitted on the door panel 111 side. A first space A as an example of a cooling space into which cooling air flows is formed between the outer heat-resistant glass 114 and the inner heat-resistant glass 115.

  A flange portion 113a is provided on the side wall side where the first slit 104 of the first recess 103 of the door cover 113 is provided. A groove portion 113b for fixing the base portion 105a of the packing 105 is provided at the tip of the flange portion 113a, and the base portion 105a of the packing 105 is sandwiched and fixed between the groove portion 113b and the door panel 111.

  On the other hand, a bent portion 111a having an L-shaped cross section is provided at the edge portion of the door panel 111 facing the flange portion 113a of the door cover 113 to form a second recess 118 having a bottom surface substantially parallel to the flange portion 113a. A second slit 119 as an example of a second air inlet is provided on the side wall of the second recess 118 of the bent portion 111a. The bent space 111a of the door panel 111 and the door cover 113 form a second space B.

  As shown in FIG. 4, in a state where the door 12 is opened and substantially horizontal, the condensed water attached to the vicinity of the first recess 103 on the upper surface of the door 12 (upper side in FIG. 4) flows into the recess 103 and the water 116 is It collects (a liquid containing water also comes out from the object to be heated, but here it will be explained only with condensed water). At that time, if the amount of overflowed water is large, the water overflows from the first recess 103 and flows into the second recess 118 through the first slit 104 and the water 117 is accumulated.

  Next, the cooling structure of the door 12 of the steam cooker 1 will be described with reference to FIG. FIG. 5 is a schematic view seen from the right side of the steam cooker 1. As shown in FIG. 5, a steam temperature raising device 50 is arranged on the ceiling side of the heating chamber 20, and the rear side of the heating chamber 20 (FIG. In FIG. 5, a steam generator 40 is arranged on the right side. On the right side of the heating chamber 20 (above the paper surface in FIG. 5), an electrical component 122 is disposed below, an electrical component 123 is disposed on the door 12 side, and cooling air as an example of air blowing means is disposed above the electrical component 122. A fan 120 is disposed. A suction port 121 is provided on the lower surface side of the main body casing 10. The cooling fan 120 supplies air sucked downward from the suction port 121 to the door 12 through the front blow port 102. Thereby, at the same time as the door 12 is cooled, the electrical component 122 and the electrical component 123 in the main casing 10 are also cooled. Therefore, the cooling function of the door 12 and the cooling function of the electrical component 122 and the electrical component 123 in the main body casing 10 can be combined with one cooling fan 120, and the cost can be reduced.

  FIG. 6 shows the flow of cooling air in the steam cooker 1 with the door 12 closed, and the air blown out from the blower fan 120 is used for cooling the side walls of the first recess 103 of the door 12. It flows into the first space A through the first and second slits (not shown). On the other hand, FIG. 7 shows the flow of the cooling air of the steam cooker 1 with the door 12 open. In this case, the air blown from the blower fan 120 is in the first recess 103 of the open door 12. It does not flow in, but blows out in front of the heating chamber 20 as it is.

  FIG. 8 (a) shows the main part of the side surface of the steam cooker 1, and exposes the water dropped from the first recess 103 of the closed door 12 through the drainage channel 103a. It is received by the part 106. FIG. 8B is a perspective view of the main part of the first recess 103 of the door 12 as viewed obliquely from above, and a drainage channel is formed below the first recess 103 (when the door is closed). 103a is provided. The drainage channel 103a has an inclined surface that gradually increases from the bottom surface of the first recess 103 toward the distal end side when the door 12 is opened. Then, when the door 12 starts to be closed from the opened state, the water accumulated in the first recess 103 flows in the direction of the arrow R1 through the drainage channel 103a and drops onto the dew receiving portion 106.

  The drainage channel is not limited to that shown in FIG. 8 (b). For example, as shown in FIG. 8 (c), the lower side of the first recess 110 provided in the door (when the door is closed) ) May be provided with a semicircular arc-shaped inclined surface 110a as an example of a drainage channel, and any drainage channel may be used as long as it drains water or the like flowing into the recess of the door.

  Further, in the drainage channel 103a shown in FIGS. 8 (a) and 8 (b), drainage cannot be performed to the dew receiving portion 106 side unless the door 12 is closed. What flowed down to the dew receiving part via the path may be used.

  Although the drainage structure using the drainage channel 103a of the first recess 103 is not shown, the same drainage structure is provided in the second recess 118 and has the same drainage function.

  According to the steam cooker 1 having the above-described configuration, the object to be heated is supplied by supplying steam from the steam generator 40 to the heating chamber 20 with the door 12 that rotates back and forth about the lower end side being closed. Heat 90. At this time, cooling air is supplied from the blower fan 120 on the main body side to the first space A in the door 12 to cool the door 12. During this cooking, the steam condenses inside the door 12 (on the heating chamber 20 side) and water droplets adhere to it. When the door 12 is opened and the object to be heated is taken out after the cooking is finished, it adheres to the inside of the door 12. Condensed water and, for example, liquid dripped from the object to be heated (water or juice adhering to the surface of the object to be heated) are drained to the dew receiving unit 106 by the drainage means (first recess 103, drainage channel 103a) of the door 12. The Therefore, in the steam cooker having a structure in which cooling air is sent to the first space A in the door 12 to cool the condensed water or the like in the first space A in the door 12 through the first slit 104. The liquid can be prevented from flowing.

  Further, by providing the first slit 104 on the side wall of the first recess 103, it becomes difficult for water to enter the first slit 104, and the water or the like flowing into the first recess 103 is drained by the drainage channel 103a. Therefore, water or the like can be prevented from entering the first slit 104 with a simple structure.

  In addition, when the bottom of the first recess 103 is made lower than the lower end of the first slit 104 with the door 12 open, water or the like accumulated in the first recess 103 flows into the first slit 104. Can be effectively prevented.

  Further, since the second space B between the first slit 104 and the first space A communicates with the first space A via the second slit 119, the door 12 is closed. In the state, the cooling air is supplied from the blower fan 120 on the main body side to the first space A in the door 12 through the first slit 104, the second space B, and the second slit 119, and the door 12 is To be cooled. And since the water etc. which flowed in from the said 1st slit 104 accumulates in the 2nd recessed part 118, and the water etc. which flowed into the 2nd recessed part 118 are drained by the 2nd drainage channel, The drainage channel structure can reliably prevent water and the like from entering the first space A.

  In addition, when the bottom of the second recess 118 is made lower than the lower end of the second slit 119 in a state where the door 12 is opened, water or the like accumulated in the second recess 118 flows from the second slit 119. Can be effectively prevented.

  In addition, by lowering the bottom surface of the second recess 118 by a dimension d (shown in FIG. 4) than the bottom surface of the first recess 103 in a state where the door 12 is opened and substantially horizontal, the first recess Water or the like accumulated in 103 is easily received by the second recess 118 via the first slit 104.

  In the above embodiment, the condensed water generated in the circulation path 60 is drained into the heating chamber 20 via the drainage path (drainage pipes 71 and 72). However, a drainage tank is provided separately and the circulation path is provided in the drainage tank. You may make it drain the condensed water produced in the inside through a drainage channel.

  Moreover, in the said embodiment, although the steam generator 40 and the steam temperature rising apparatus 50 were provided and the steam cooker which heats and cooks a to-be-heated material with superheated steam was demonstrated, the steam cooker of this invention does steam. What is necessary is just to provide the steam generator which generate | occur | produces, and the heating chamber for heating a to-be-heated material with the steam supplied from the said steam generator.
