RU
- the operation of steam cooker 1A is as follows. First, the door 11 is opened, the 7 tank 71 is pulled out from the water tank chamber 70, and water is poured into the tank from a water supply port (not shown). Push the filled water tank 71 into the water tank chamber 70 and set it in place. After confirming that the end of the water supply pipe 72 is firmly connected to the inlet 64 of the water supply pipe 63, close the door 11 and press the power key on the operation panel 13 to turn on the power. Then, the motor 76 of the water supply pump 73 rotates, and water supply to the steam generator 50 starts. At this time, the drain valve 54 and the cleaning valve 66 are closed.
- the water overflows from the end of the water supply pipe 63 like a fountain, and falls to the bottom of the pot 51 while wetting the fins 62 of the heat transfer unit 60. Then, it accumulates from the bottom of the pot 51.
- the water level sensor 68 detects that the water level has reached the middle of the length of the heat transfer unit 60, the water supply is stopped once.
- the water level in the pipe on the inlet side of the overflow pipe 67 reaches the same level as the pot 51.
- power supply to steam generation heater 69 is started.
- the steam generation heater 69 heats the water in the pot 51 through the side wall of the pot 51.
- the heat transfer unit 60 in which the plurality of fins 62 are radially arranged has a large heat transfer area, and the water in the pot 51 is quickly heated. Further, since the fins 62 arranged radially support the pot 51 from the inside like the spokes of a wheel, the strength of the steam generator 50 is increased.
- the energization of the blower 25 and the gas heating heater 41 is also started.
- the blower 25 sucks the steam in the heating chamber 20 from the suction port 24 and sends out the steam to the external circulation path 30.
- the centrifugal fan 26 is used to send out steam, a higher pressure can be generated as compared with a propeller fan. As a result, the steam is pumped through the external circuit 30. Since the centrifugal fan 26 is rotated at high speed by the DC motor, the airflow has a high pressure and a very high flow velocity.
- the cross-sectional area of the flow path may be smaller than the flow rate. Therefore, the duct that forms the main body of the external circulation path 30 can have a circular cross section and a small force, and the surface area of the external circulation path 30 can be reduced as compared with the case where the external circulation path 30 is formed by a rectangular cross section duct. . Therefore, despite the hot steam passing through the inside, heat dissipation from the external circulation path 30 is reduced, and the energy efficiency of the steam cooker 1A is improved. Even when the external circulation path 30 is wound with a heat insulating material, the amount of the heat insulating material is small.
- the damper 45 opens the inlet of the duct 33 of the external circulation path 30 and closes the exhaust port 32.
- the gas enters the duct 33 from the duct 31, and further enters the subcavity 40 via the duct 36. After being heated by the gas heating heater 41 in the subcavity 40, the gas is jetted downward from the upper jet hole 43.
- the steam that has exited the rear-stage injector 37 flows into the subcavity 40 at high speed.
- the steam that has entered the subcavity 40 is heated to 300 ° C. by the gas heating heater 41 and becomes superheated steam.
- the superheated steam expands due to a rise in temperature and gushes out of the upper fumarole 43.
- the control device 80 displays an indication to that effect on the operation panel 13 and emits a signal sound.
- the user who has learned from the sound and display that cooking is ready opens the door 11 and puts the object to be heated F into the heating chamber 20.
- the control device 80 switches the posture of the damper 45, closes the entrance of the duct 33, and opens the exhaust port 32. Heating chamber of 20 The steam inside is sucked in by the blower 25 and discharged from the exhaust port 32. By closing the entrance of the duct 33, the superheated steam does not blow out from the upper fumarole 43, so that the user is not burned to the face or hands.
- the damper 45 keeps the posture of opening the exhaust port 32 and closing the entrance of the outside 33 while the door 11 is open.
- the stopped blower 25 is started to exhaust air from the exhaust port 32, a time lag occurs until a steady state of the blower is reached.
- the blower 25 is already The vehicle is driving and the time lag is zero.
- the circulating air flowing around the heating chamber 20 and the external circulation path 30 becomes the exhaust flow from the exhaust port 32 as it is, so there is a time lag for the air flow to change direction.
- the duct 33 When discharging steam from the heating chamber 20, the duct 33 is closed and the supply of steam to the heating chamber 20 is stopped. For this reason, the vapor pressure or the amount of vapor in the heating chamber 20 decreases quickly, and the time until the door 11 can be opened is further reduced.
- the situation in which the user has opened the door 11 with great force can be transmitted to the control device 80 as follows, for example, as follows. That is, a latch for keeping the door 11 closed is provided between the cabinet 10 and the door 11, and a latch lever for unlocking the latch is provided so as to be exposed from the handle 12. A switch that opens and closes in response to the movement of the latch or the latch lever is placed inside the door 11 or the handle 12, and when the user grips the handle 12 and the latch lever to perform the unlocking operation, the switch opens the control device. The signal is sent to 80.
- the gas discharged from the exhaust port 32 contains a large amount of vapor, and it is problematic to discharge the gas as it is. Therefore, the gas exhausted from the exhaust port 32 is also discharged through the maze-shaped dew passage provided in the cabinet 10 to remove moisture and then to the outside of the cabinet 10. The water that flows down from the condensation passage is guided to the saucer 21 and is treated with water generated from other causes after cooking.
- the control device 80 continues to operate the blower 25 for a time until a predetermined condition is satisfied.
- the predetermined condition is that “a predetermined time has elapsed after the opening operation of the door 11 is detected”. For this reason, door 11 was opened At this time, the user's power also generates an airflow directed toward the back of the heating chamber 20, and the blowing of steam is blocked, so that the safety of the user can be ensured.
- the “predetermined time” is set as a reference, “the time during which the steam is exhausted to such an extent that the steam is no longer blown toward the user even if the blower 25 is completely stopped”.
- the predetermined condition may be set as follows. In other words, it is "confirmation of full opening of the door 11". By doing so, a directional airflow is generated in the back of the heating chamber 20 by the user until the door 11 is fully opened until the door 11 is fully opened, and the blowing of high-temperature gas is prevented. For this reason, the safety after opening the door 11 can be ensured.
- the predetermined condition can be set as follows. That is, "the predetermined time after the door 11 is fully opened". In this way, a directional airflow is generated from the user to the back of the heating chamber 20 from the time when the door 11 is opened until the door 11 is fully opened, and until a predetermined time has elapsed therefrom, and the hot gas is generated. The balloon is blocked. For this reason, safety after opening the door 11 can be ensured.
- the definition of "predetermined time” is the same as before.
- the blower 25 When the door 11 is opened to take out the object to be heated F after the completion of cooking, the blower 25 must be stopped after a predetermined time has elapsed. If the door 11 is opened during cooking, the blower 25 may be continued to operate as it is not necessary to stop the blower 25 because a predetermined time has elapsed.
- the damper 45 opens the entrance to the duct 33 and returns to the posture in which the exhaust port 32 is closed. With this as a signal, the ejection of superheated steam from the upper fumarole 43 is resumed, and cooking of the object to be heated F is started.
- the superheated steam that comes into contact with the surface of the heated object F releases latent heat when dew forms on the surface of the heated object F. This also heats the object F to be heated.
- the energy efficiency of the steam cooker 1A is high. Then, the gas containing the superheated steam is directed downward from the plurality of upper fumaroles 43 distributed on the bottom panel 42 of the subcavity 40 over almost the entire panel. Because of the ejection, almost the entire heated object F is wrapped in vapor from above. The fact that the superheated steam collides with the object to be heated F and the large area of the collision allow the heat contained in the superheated steam to be transferred to the object to be heated F quickly and efficiently.
- the gas that has entered the subcavity 40 is heated by the gas heating heater 41 and expands, so that the force of the ejection increases and the collision speed with the object F to be heated increases. As a result, the object to be heated F is heated more quickly.
- the centrifugal fan 26 can generate a higher pressure than the propeller fan, it is possible to increase the ejection power from the upper ejection holes 43. As a result, the injection distance of the superheated steam is extended, and the object to be heated F can be strongly heated. Since the centrifugal fan 26 is rotated at a high speed by a DC motor to blow air strongly, the above-mentioned effect is more remarkably exhibited.
- the strong wind force of the blower device 25 is very useful for quickly exhausting the air from the exhaust port 32 when the door 11 is opened.
- the suction port 24 is located below the side wall of the heating chamber 20 (below the height of the object to be heated F), and the steam ejected from the upper blast holes 43 travels straight without deflecting and hits the object to be heated F before being sucked. Mouth 24 sucks. Therefore, the heat transfer capability to the object to be heated F is maintained at a high level. In addition, since the steam spouted from above is sucked into the lower part of the side wall, when the door 11 is opened, the steam is less likely to rush toward the user, so that the safety is high.
- suction port 24 Since the suction port 24 is directed downward, a lateral force is further applied to the ejected steam, and the deflection of the steam can be further prevented. In addition, even if oil splashes from the surface of the object to be heated F, it does not contaminate the inner surfaces of the air blower 25 and the external circulation path 30 which are sucked into the suction port 24 for easy access.
- the gas heating heater 41 Absorbs radiant heat well.

- the operation of steam cooker 1B is as follows. First, the door 11 is opened, the water tank 71 is pulled out of the water tank chamber 70, and water is poured into the tank from a water supply port (not shown). Push the filled water tank 71 into the water tank chamber 70 and set it in place. After confirming that the end of the water supply pipe 72 is firmly connected to the inlet 58 of the water supply channel, the heat source F is put into the heating chamber 20 and the door 11 is closed.

Then, steam generation is not started until the water shortage is resolved.
- the damper 97 closes the duct 96 serving as an exhaust port that passes from the duct 31 to the container 93a.
- the steam pumped from the blower 25 enters the steam suction ejector 34 from the duct 31 and further enters the subcavity 40 via the duct 35.
- the saturated steam generated in the pot 51 is sucked into the steam suction ejector 34 and joins the circulating airflow.
- the steam that has exited the steam suction ejector 34 flows into the subcavity 40 through the duct 35.
- the steam entering the subcavity 40 is heated to 300 ° C. by the gas heating heater 41 and becomes superheated steam.
- Part of the superheated steam is ejected downward from the upper fumarole 43.
- Another part of the superheated steam goes to the subcavity 44 through the duct 45 and gushes laterally from the side flares 46.
- Figs. 21 and 22 show the flow of steam in a state where the object F to be heated is not put into the heating chamber 20. From the upper fumarole 43, steam gushes downward with a force reaching the bottom of the heating chamber 20. The steam hitting the bottom of the heating chamber 20 turns outward. The steam begins to rise after exiting the downward flowing airflow. Since steam, especially superheated steam, is light, such a change occurs naturally. As a result, the interior of the heating chamber 20 is In addition, a convection in the form of a down flow at the center and an ascending flow at the outside thereof occurs.
- the arrangement of the upper fumarole 43 is also devised. That is, as shown in FIG. 19, the arrangement of the upper fumarole 43 is dense at the center of the bottom panel 42 and sparse at the periphery. As a result, at the peripheral portion of the bottom panel 42, the force for blowing down the steam is weakened and does not hinder the steam from rising, so that the convection appears more clearly.
- the object to be heated F When the object to be heated F is placed in the heating chamber 20, it is heated to about 300 ° C, and the upper fumarole 43 force The superheated steam colliding with the object to be heated F collides with the object to be heated F. Tell During this process, the steam temperature drops to about 250 ° C. The superheated steam in contact with the surface of the object to be heated F releases latent heat when the surface of the object to be heated F is dewed. This also heats the object F to be heated.
- the steam spouted laterally from the side flares 46 enters the rack 22 from the left and right and meets under the object F to be heated.
- the direction of steam emission from the side flares 46 is tangential to the surface of the object F to be heated. It stays under the heated material F and overflows. Therefore, the same effect as when steam is blown in the normal direction of the surface of the object to be heated F occurs, and the heat of the steam is reliably transmitted to the lower surface of the object to be heated F.
- the object F to be heated is cooked by the steam from the side blast holes 46 to the portion where the steam from the upper blast holes 43 does not hit, in the same manner as the upper surface portion. As a result, it is possible to obtain a uniform and good-looking cooking result. Further, since the object to be heated F receives heat uniformly from the entire surface, it is sufficiently heated to the center in a short time.
- the vapor from the side flares 46 also dropped from about 300 ° C at first to the temperature of about 250 ° C after hitting the object to be heated F. Conduct heat. In addition, when the condensation on the surface of the heated object F releases latent heat, the heated object F is heated.
- the steam from the side blast holes 46 applies heat to the lower surface of the article to be heated F, and then joins the convection generated by the steam from the upper blast holes 43.
- the convective steam is sucked into the suction port 28 sequentially.
- the vehicle returns to the heating chamber. In this manner, the circulation in which the steam in the heating chamber 20 exits the external circulation path 30 and returns to the heating chamber 20 is repeated.
- the container 93a communicating with the outside of the machine is formed to have a large flow path area, the steam blowing speed is reduced. Therefore, it is not possible for objects outside the aircraft to suffer damage due to the vigorous impact of steam.
- the side fumaroles 46 are far from the subcavity 40, and are more disadvantageous in terms of steam ejection than the upper fumaroles 43. However, since the sum of the areas of the left and right side flares 46 is made larger than the sum of the areas of the upper flares 43, a sufficient amount of steam is guided to the side flares 46 and the object to be heated is heated. Heat unevenness of the upper and lower surfaces of F is reduced. [0153] When the steam is continuously generated by the steam generator 50, the water level in the pot 51 drops. When the pot water level sensor 56 detects that the water level has dropped to a predetermined level, the control device 80 restarts the operation of the water supply pump 57.
- the water supply pump 57 sucks the water in the water tank 71 and supplies the evaporated water to the pot 51.
- the control device 80 stops the operation of the water supply pump 57 again.
- the water level in the pot 51 rises above a predetermined level. to continue.
- the water sent from the water supply pump 57 overflows from the overflow pipe 98 to the container 93a and flows into the exhaust duct 93.
- the water in the pot 51 does not enter the external circuit 30 from the steam suction injector 34.
- the water that has entered the exhaust duct 93 flows to the heating chamber 20.
- the container 93a has a large capacity since it has a large flow path area. Therefore, even if a large amount of water overflows, it can be received with sufficient margin and can be slowly drained from the exhaust duct 93.
- the control device 80 displays an indication to that effect on the operation panel 13 and emits a signal sound.
- the user who has heard the completion of the cooking by the sound and the display, opens the door 11 and takes out the heated material F from the heating chamber 20. Also at this time, the open / close state of the damper 97 is switched, and the steam in the heating chamber 20 is exhausted from the exhaust path. Therefore, the user can safely take out the object F to be heated.
- the control device 80 continues to operate the blower until a predetermined condition is satisfied. For this reason, when the door 11 is opened, the user's force also generates a directional airflow in the back of the heating chamber 20, and the blowing of steam is prevented. When the predetermined condition is satisfied, the blower 25 stops, and the damper 97 returns to the closed position.
- the same predetermined conditions as in the first embodiment can be adopted.
- a force that employs a configuration in which the steam in the heating chamber 20 is returned from the external circulation path 30 to the heating chamber 20 via the subcavity 40 and a different configuration is also possible.
- a force that employs a configuration in which the steam in the heating chamber 20 is returned from the external circulation path 30 to the heating chamber 20 via the subcavity 40 and a different configuration is also possible.
- the steam may be continuously released from the exhaust path.
- the present invention is applicable to all cookers that cook with high-temperature gas, whether for home use or business use.
