Description

  The present invention relates to a steam cooker.

  2. Description of the Related Art Conventionally, there is a steam cooker that uses steam to heat an object to be heated such as food, and sends superheated steam into an oven (see Japanese Patent Application Laid-Open No. 8-49854 (Patent Document 1)). This steam cooker includes a steam generator that generates steam by providing a heater along a vertical plane in the pot, and a steam superheater that generates superheated steam by heating the steam generated by the steam generator. The superheated steam generated by the steam superheater is fed into the oven to cook food.

  Further, as a cooking device that takes measures against water entering from the outside, there is a high-frequency heating device provided with a cover (see Japanese Patent Laid-Open No. 3-222280 (Patent Document 2)). In this high-frequency heating device, a cover that covers the high-voltage generating circuit is disposed, and a space is provided between the rear end of the cover and the rear portion of the main body case. In this way, when water spills from the cup or the like on the main body case, the water that has entered the main body case from the air intake holes provided in the main body case will be separated from the rear end of the cover and the main body case formed by the bottom plate of the air guide. It flows down to the bottom plate of the main body case from the space provided between the rear portion and is discharged out of the main body case through an exhaust hole provided in the bottom plate of the main body case.

  By the way, in the case of countermeasures against the ingress of water that hardly occurs unless the user makes a mistake like the high-frequency heating device disclosed in the above-mentioned Patent Document 2, Since the water discharged outside the case evaporates naturally, there is no particular need for treatment of the discharged water.

On the other hand, in the steam cooker as shown in the above-mentioned Patent Document 1, steam leakage may occur in the oven cabinet or the steam supply circuit due to poor bonding or aging. The leaked steam condenses in the outer cabinet and falls as water droplets. In the case of such a steam leak, once it occurs, it continuously occurs. Therefore, the water countermeasure disclosed in Patent Document 2 is not in time, and the bottom plate of the casing, the table on which the steam cooker is placed, etc. are always moistened, and there is a problem that mold is generated.
Japanese Patent Laid-Open No. 8-49854 JP-A-3-222280

  Therefore, an object of the present invention is to provide a sanitary steam cooker in which the condensed water of leaked steam is naturally evaporated quickly and no mold or the like is generated.

In order to solve the above problems, the steam cooker of the present invention is:

Has been.

  Next, a control system of the steam cooker 1 will be described.

  The control device 80 includes a microcomputer, an input / output circuit, and the like, and as shown in FIG. 4, the blower fan 28, the first steam heater 52, the second steam heater 53, the damper 68, and the drain valve. 70, the steam generating heater 42, the operation panel 11, the water tank water level sensor 36, the water level sensor 43, the temperature sensor 81 for detecting the temperature in the heating chamber 20 (shown in FIG. 3), and the heating chamber 20 A humidity sensor 82 for detecting the humidity inside the pump and the pump 35 are connected. Based on the detection signals from the water tank water level sensor 36, the water level sensor 43, the temperature sensor 81, and the humidity sensor 82, the blower fan 28, the first steam heater 52, the second steam heater 53, the damper 68, the waste water. The valve 70, the steam generating heater 42, the operation panel 11 and the pump 35 are controlled according to a predetermined program.

  Hereinafter, operation | movement of the steam cooker 1 which has the said structure is demonstrated according to FIG. 3 and FIG. When a power switch (not shown) of the operation panel 11 is pressed, the power is turned on, and the cooking operation is started by operating the operation panel 11. Then, first, the control device 80 closes the drain valve 70 and starts the operation of the pump 35 in a state where the exhaust passage 67 is closed by the damper 68. Then, water is supplied from the water tank 30 into the pot 41 of the steam generator 40 via the first to fourth water supply pipes 31 to 34 by the pump 35. Thereafter, when the water level sensor 43 detects that the water level in the pot 41 has reached a predetermined water level, the pump 35 is stopped to stop water supply.

  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.

  When the steam generating heater 42 is energized 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 and second steam heaters of the steam temperature raising device 50 are turned on. Energize 52 and 53. 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 external circulation path 60. In that case, since the centrifugal fan is used for the ventilation fan 28, a high pressure can be generated compared with the case where a propeller fan is used. 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 external circulation path 60 at the location of the steam suction ejector 44. Then, the steam discharged from the steam suction ejector 44 flows into the steam temperature raising device 50 through the third pipe 63 at a high speed.

  And the steam which flowed into the said steam temperature rising apparatus 50 is heated by the 1st, 2nd steam heating heaters 52 and 53, and becomes a superheated steam of about 300 degreeC (it changes with cooking contents). A part of this 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, the other 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 the left and right sides of the steam temperature raising device 50.

  Thus, the superheated steam ejected from the ceiling side of the heating chamber 20 is vigorously supplied toward the heated object 90 side in the center, and the superheated steam ejected from the left and right side surfaces of the heating chamber 20 is supplied to the tray 21. After the collision, the material to be heated 90 is supplied while being wrapped from below the material 90 to be heated. As a result, in the heating chamber 20, convection occurs in such a manner that it blows down at the center and rises outside thereof. Then, the convection steam is sequentially sucked into the suction port 25 and repeatedly circulates through the external circulation path 60 and returns to the heating chamber 20 again.

  In this way, by forming a convection of superheated steam in the heating chamber 20, the superheated steam from the steam heating device 50 is blown to the ceiling steam while the temperature and humidity distribution in the heating chamber 20 is kept uniform. It is possible to eject the gas from the outlet 55 and the side air outlet 22 and efficiently collide with the object to be heated 90 placed on the rack 24. Thus, the object to be heated 90 is heated by the collision of the superheated steam. In that case, the superheated steam that has contacted 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 reliably and promptly applied to the entire surface of the article 90 to be heated. Therefore, it is possible to realize cooking with no spots and good finish.

  In addition, when the time elapses during the cooking operation, 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 that time, the steam 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 cooking, the control device 80 displays a cooking end message on the operation panel 11, and a buzzer (not shown) provided on the operation panel 11 sounds a signal. When a user who knows the end of cooking by these messages and buzzer opens the door 12, the control device 80 detects that the door 12 has been opened by a sensor (not shown) and opens the damper 68 of the exhaust passage 67. Open instantly. Then, the first pipe 61 of the external circulation path 60 communicates with the exhaust duct 65 via 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, and the exhaust passage 67. And is discharged from the exhaust port 66 through the exhaust duct 65. This damper operation functions similarly even if the user opens the door 12 during cooking. Therefore, the user can safely take out the object 90 to be heated from the heating chamber 20 without being exposed to steam.

  By the way, when steam cooking is performed as described above, steam leakage may occur in the heating chamber 20, the steam heating device 50, or the external circulation path 60 due to poor bonding or aging. Therefore, in the present embodiment, the following countermeasures for condensation of leaked steam are taken.

  Fig.5 (a) is the side view which looked at the steam cooker 1 of the state which removed the right side cabinet 10 from the right side. Moreover, FIG.5 (b) is the partial view which looked at the steam cooker 1 of the state which removed the door 12 and the front cabinet 10 from the front. As shown in FIG. 5, on the right side of the heating chamber 20, electrical components such as a microcomputer constituting the control device 80, an input / output circuit, a solenoid valve for opening and closing the drain valve 70, and a control circuit for controlling the operation of each device are provided. A component 101 is arranged.

  In the present embodiment, a cover 102 is provided to cover the upper and side portions of the electrical component 101 and the boundary portion with the heating chamber 20. At that time, the top plate 102 a of the cover 102 is provided with an inclination that goes down toward the heating chamber 20. Further, a gap of about 0.5 mm to 2 mm is provided between the side plate 102 b of the cover 102 and the heating chamber 20. Further, a recess 103 is formed on the bottom plate of the cabinet 10 across the bottom surface of the heating chamber 20 to constitute a water reservoir.

  The cover 102 having the above configuration functions as follows. For example, as shown in FIG. 5 (b), when a steam leak 104 occurs in the steam temperature raising device 50, water droplets generated by condensation above the electrical component 101 are indicated by broken line arrows (A), It drops on the top plate 102a of the cover 102. Then, since the top plate 102a is provided with an inclination toward the heating chamber 20, the water droplets on the top plate 102a are heated to superheated steam as indicated by the broken arrow (B). It flows toward the heating chamber 20 and further flows down through the gap between the side plate 102b and the heating chamber 20 while traveling along the side plate 102b of the cover 102. In this case, the distance between the side plate 102b and the heating chamber 20 is about 0.5 mm to 2 mm, and the side plate 102b is disposed close to the high temperature heating chamber 20. Therefore, the water flowing down through the side plate 102b cannot flow smoothly due to the surface tension. As a result, some of the water droplets spontaneously evaporate due to heat radiation from the heating chamber 20.

  Here, the cover 102 is not provided on the anti-heating chamber 20 side of the electrical component 101 and is open. Therefore, the heat radiated from the electrical component 101 and the radiant heat from the heating chamber 20 via the side plate 102b can be quickly released to the outside of the cover 102, and the electrical component 101 can be prevented from being exposed to a high temperature. .

  Further, the water droplets remaining without evaporating flow into the concave water reservoir 103 formed on the bottom plate of the cabinet 10. Here, the water reservoir 103 is formed in a large area directly under the high temperature heating chamber 20. Therefore, evaporation of the condensed water that has flowed into the water reservoir 103 is urged to evaporate quickly.

  As described above, according to the present embodiment, the shape of the cover 102 that covers the periphery of the electrical component 101 receives the dripping water and flows toward the high-temperature heating chamber 20, and the wall surface of the high-temperature heating chamber The shape can be made to flow down along. Therefore, the electrical component 101 can be protected from water droplets generated by the condensation of the leaked steam 104. Furthermore, it can be evaporated naturally using a heat source.

  Further, the bottom plate of the cabinet 10 is formed with a water reservoir 103 formed of a large-area recess over the bottom surface of the high-temperature heating chamber 20. The condensed water remaining without being evaporated when flowing through the top plate 102 a and the side plate 102 b of the cover 102 extends thinly and accumulates in the water reservoir 103. Therefore, the water in the water reservoir 103 can be quickly evaporated by the heat from the heating chamber 20, and mold can be prevented from becoming unsanitary.

  That is, according to this embodiment, when taking measures against condensed water of leaked steam, drain piping is not required, condensed water can be eliminated by natural evaporation, and it is cheap, safe and hygienic. It is possible to provide a steam cooker for household use.

  In the above embodiment, the entire top plate 102a of the cover 102 is provided with an inclination that goes down toward the heating chamber 20 side. However, the present invention is not limited to this, and a first inclined portion that descends toward the heating chamber 20 is provided in a part of the top plate 102a, and the remaining portion of the top plate 102a is provided on the first inclined portion side. You may provide the 2nd inclination part which goes down. In short, it is only necessary to have a shape capable of receiving dripping water and flowing toward the heating chamber 20 side.
