(B view direction cross section of FIG. 1) is shown. Note that the schematic cross-sectional view of FIG. 2 is not a strict cross-sectional view in the direction of A in FIG. 1, but the positional relationship is appropriately changed for convenience of explanation. FIG. 4 is an explanatory diagram of the attachment / detachment state of each part of the steam treatment apparatus according to Embodiment 1 of the present invention. In addition, in each figure, the example of the rice cooker is shown as a heating cooker.

  The steam processing device 30 is a device that cools and condenses steam generated from the steam generating port 7 of the heating cooker 1, and includes a steam recovery lid 10 and a connecting pipe at the steam generating port 7 of the heating cooker 1. It is detachably connected via 20.

  The cooking device 1 includes a main body 1a, a heating container 2 that is built in the main body 1a, accommodates an object to be heated, a heat supply source 3 that generates energy for heating the heating container 2, and an upper surface opening of the main body 1a. And a lid 5 that is freely closed. The lid 5 is configured to be in close contact with the upper surface of the heating container 2 via the lid seal rubber 4, and is configured to prevent vapor from leaking between the lid 5 and the upper surface of the heating container 2. In addition, a steam passage 6 for discharging steam generated in the heating container 2 to the outside is formed inside the lid body 5, one end of the steam passage 6 opens to the heating container 2, and the other end is exposed to the outside. A steam recovery lid 10 is detachably attached to the steam generation port 7 which is an opening on the outside.

  The steam recovery lid 10 has a steam passage 11 through which steam generated from the steam generating port 7 passes, and allows the steam discharged from the steam generating port 7 to pass through the steam passage 11 and be discharged to the connecting pipe 20. . Further, in the middle of the steam passage 11, a mouse 12 is formed for damming out spills (spills) other than steam from the heating cooker 1 and returning to the heating container 2. Even if an effluent other than steam is discharged from the steam generation port 7 by this mouse rod 12, all the effluent is blocked by the mouse rod 12 and prevented from flowing out to the connecting pipe 20. .

  The steam processing device 30 opens and closes a water tank 31 for storing water for performing steam processing (processing for condensing steam discharged from the steam generating port 7 in the steam processing device 30) and an upper portion of the water tank 31. And a tank cover 32.

  The water tank 31 is provided with a water level scale 35 on the side wall surface for instructing the water level for performing the steam treatment. The distance H (see FIG. 3) between the height position of the water level scale 35 and the height position of the bottom surface of the auxiliary container 33 described later is designed to be a predetermined distance H. This distance H will be described later.

  As shown in FIG. 3, the tank cover 32 is detachably attached to the water tank 31 by engaging and disengaging an engagement hole 36 formed in the tank cover 32 and an engagement protrusion 37 formed on the outer peripheral wall of the water tank 31. Has been.

  Further, a communication pipe 34 that communicates the connection pipe 20 and the inside of the water tank 31 is formed on the lower surface of the tank cover 32 so as to hang downward from the lower surface of the tank cover 32. In the middle of the communication pipe 34, specifically, at the connecting portion between the communication pipe 34 and the lower surface of the tank cover 32, the water condensed in the water tank 31 by the steam treatment is returned to the heating cooker 1. An auxiliary container 33 is formed for prevention. A drain hole 39 for draining water accumulated in the auxiliary container 33 is formed in the bottom surface of the auxiliary container 33. The drain hole 39 is normally closed with a removable plug 40. It has become.

  The communication pipe 34 is integrally formed with the tank cover 32 so that the lower end opening 34 a of the communication pipe 34 is located at a certain depth in the water tank 31 when the tank cover 32 is closed to the water tank 31. . This is because if the submergence depth of the communication pipe 34 with respect to the water tank 31 is not set appropriately, and the steam discharged from the lower end opening 34a of the communication pipe 34 is used as the water in the water tank 31 when it is shallower than the required depth. This is because they cannot be brought into sufficient contact, resulting in poor steam treatment. Therefore, this constant depth position is set so that all of the steam generated from the steam generating port 7 can be condensed, and specifically, the speed at which the steam bubbles rise and the speed at which the steam cools and returns to the water. It is determined from Sato.

  In addition, the steam treatment apparatus 30 has a double wall structure with another wall provided outside the wall of the water tank 31, so that even if the internal water becomes high temperature after the steam treatment, there is no burn. The steam processing device 30 can be touched. In the tank cover 32, a vent hole 38 is formed at a position different from the portion where the auxiliary container 33 is formed. The operation of the vent 38 will be described later.

  With the above configuration, the steam discharged from the steam generating port 7 of the heating cooker 1 passes through the steam passage 11 and the connecting pipe 20 in the steam recovery lid 10, flows into the steam processing device 30, and enters the auxiliary container. 33 and the communication pipe 34 are discharged from the lower end opening 34 a of the communication pipe 34 into the water in the water tank 31.

Next, operation | movement of the steam processing apparatus 30 is demonstrated.
First, the tank cover 32 is removed from the water tank 31, and water W is poured into the water tank 31 from the outside to the water level scale 35. And the foodstuff F is put in the heating container 2, and the operation button which is not shown in figure of the heating cooker main body 1a is pressed down, and heating cooking is started. Thereby, the heating container 2 is heated by the heat supply source 3, and the water contained in the cooked product F in the heating container 2 boils to generate steam.

  And while the amount of steam is small, the steam condenses in the steam recovery lid 10 and passes through the steam passage 6 and returns to the heating container 2. The pressure rises above atmospheric pressure, and the steam generated in the heating container 2 is pushed out by the pressure and passes through the steam passage 6, and passes from the steam generation port 7 to the steam passage 11 of the steam recovery lid 10. enter. Here, since the heating container 2 and the lid 5 of the heating cooker 1 are sealed by the lid seal rubber 4, the steam in the heating container 2 enters the steam recovery lid 10 without leaking outside. ing.

  Then, the steam that has entered the steam passage 11 of the steam recovery lid 10 flows into the steam processing device 30 through the connecting pipe 20. The steam that has flowed into the steam processing apparatus 30 first passes through the auxiliary container 33, further passes through the communication pipe 34, and is jetted from the lower end opening 34 a into the water in the water tank 31. Then, the jetted steam comes into contact with the water in the water tank 31 to condense, and returns to the water.

  By treating the steam in this way, it is possible to prevent the steam generated from the heating cooker 1 from leaking to the outside, and to prevent an unpleasant increase in moisture during cooking.

  And since the steam which flowed in the steam processing apparatus 30 returns to water in the water tank 31, as the cooking in the heating cooker 1 progresses, the amount of water in the water tank 31 gradually increases and the water level gradually increases. Go. Here, since the tank cover 32 is provided with the vent hole 38, the air corresponding to the increased water level is released to the outside through the vent hole 38, and the pressure in the steam processing apparatus 30 does not rise during the steam processing. Steam treatment can be performed smoothly.

  And when cooking is complete | finished, the inside of the heating container 2 will cool and a pressure will fall. As a result, the pressure in the connecting pipe 20 and the auxiliary container 33 similarly decreases, and the water in the water tank 31 is sucked up from the lower end opening 34a of the communicating pipe 34. Then, the sucked water enters the auxiliary container 33. Here, if the volume of the auxiliary container 33 is A [liter] and the volume when all of the steam from the cooked product F in the heating container 2 is condensed is B [liter], then A> B. In addition, the volume of the auxiliary container 33 is sufficiently large. Therefore, all of the water sucked up from the lower end opening 34a of the communication pipe 34 is accumulated in the auxiliary container 33, and is returned to the heating container 2 through the connecting pipe 20 to prevent the food from being wetted. Is possible.

  Next, when cooking is completed and the lid 5 of the heating cooker is opened, the pressure in the heating container 2 returns to the original atmospheric pressure. As a result, the force sucking up the water in the water tank 31 disappears, so that the water in the auxiliary container 33 flows out from the lower end opening 34 a of the communication pipe 34 and returns to the water tank 31.

  Here, in this example, the water level scale 35 is provided in the water tank 31, and an appropriate amount of water is stored in the water tank 31, so that the steam treatment of the heating cooker 1 can be performed efficiently and stably. There is one feature. Next, the setting of the amount of water will be described.

FIG. 5 is a view showing the water temperature measurement result after steam treatment when the water amount in the water tank is changed variously, and the horizontal axis indicates the initial water amount [mL] in the water tank 31 and the vertical axis. Indicates the water temperature [° C.] in the water tank 31 after the steam treatment.
As shown in FIG. 5, when the initial water amount is set to V1 or less, the water temperature reaches 100 ° C., so that the steam treatment cannot be performed (that is, the steam cannot be cooled to be condensed). For this reason, the amount of water in the water tank 31 is set to a water amount equal to or higher than V2 at which the water temperature is 90 ° C. or lower in consideration of the heat resistance of the resin material constituting the water tank 31. In addition, when it is preferable to set the water temperature to 60 ° C. or less in order to prevent burn accidents during cleaning after cooking, the water amount is set to V3 or more.

  By providing the water level scale 35 at a position that satisfies the amount of water set in this manner, the steam treatment can be performed stably and safely by the steam treatment device 30.

  In addition, this example also has a feature in that it is possible to prevent water from overflowing from the steam treatment apparatus 30 by steam treatment. Next, the feature portion will be described.

  When cooking is started, it is performed in a state where no water remains in the auxiliary container 33. However, in the unlikely event that cooking is started in a state where water remains, the lid 5 after the end of cooking. When the container is opened, the residual moisture returns to the water tank 31 more than when it is normal (when processing is performed with no water remaining in the auxiliary container 33). Therefore, if such a case is assumed and the steam processing apparatus 30 is not appropriately dimensioned, water may overflow from the steam processing apparatus 30. In this example, in order to prevent this, the position of the water level scale 35 is set to an optimum position to prevent the overflow of water. Details will be described below.

  Specifically, the water level scale 35 is provided at a position separated by a predetermined distance H from the height position of the bottom surface of the auxiliary container 33. That is, when the water level height that rises when all of the steam from the cooked product F in the heating container 2 returns to water is Δh1, and the remaining water is temporarily full in the auxiliary container 33, the auxiliary container 33 If the water level height that rises when water of volume A [liter] returns to the water tank 2 is Δh2, the distance H is set to a value that satisfies the following expression (1).

  H> = Δh1 + Δh2 (1)

  And by providing the water level scale 35 at a position satisfying the distance H obtained in this way, even if cooking is started while remaining water remains in the auxiliary container 33, water is removed from the steam treatment device 30. It is possible to prevent overflow.

  From the above, the position of the water level scale 35 is set to a position that indicates the amount of water of V2 or V3 or more and further satisfies the distance H.

  As described above, according to the first embodiment, the water level scale 35 for instructing the water level for performing the steam treatment is provided so that the amount of water necessary for the steam treatment can be surely entered by the user. Since the lower end opening 34a of the communication pipe 34 of the tank cover 32 is positioned at a certain depth in the water tank 31 when the water tank 31 is closed by 32, steam generated from the heating cooker 1 Can be steamed efficiently and stably.

  The water level indicated by the water level scale 35 is a position for instructing the amount of water set so that the temperature in the water tank 31 after condensing steam becomes 90 ° C. or less. Then, the cooking device 1 is driven, so that the steam generated from the cooking device 1 can be reliably steamed.

  Moreover, since the said fixed depth position of the lower end opening 34a of the communicating pipe 34 is a position set so that all of the steam generated from the steam generating port 7 can be condensed, the steam generated from the heating cooker 1 can be reduced. Steam treatment can be performed efficiently and stably.

  Moreover, since the auxiliary container 33 for temporarily storing the water sucked from the communication pipe 34 after cooking is provided, it is possible to prevent the sucked water from returning to the heating cooker 1 and wetting the cooked product. it can.

  Further, the height distance H from the bottom surface of the auxiliary container 33 to the water level scale 35 is increased by the water level height that rises when all of the steam that has come out of the cooked product in the heating cooker 1 returns to the water in the water tank 31. Δh1 and the sum of the water level height Δh2 that rises when the volume of water in the auxiliary container 33 returns to the water tank 31, so cook with the remaining water remaining in the auxiliary container 33 Even if is started, it is possible to prevent water from overflowing from the steam treatment device 30.

  Further, since the discharge hole 39 is provided on the bottom surface of the auxiliary container 33 and the removable plug 40 is provided to close the discharge hole 39, the remaining water in the auxiliary container 33 can be discarded after the cooking is completed, and the washing can be performed easily. it can.

Embodiment 2. FIG.
FIG. 6 is a sectional view showing a steam treatment apparatus according to Embodiment 2 of the present invention.
In the steam processing apparatus 30A of the second embodiment, the bottom surface of the auxiliary container 33 of the steam processing apparatus 30 of the first embodiment shown in FIG. 3 is funnel-shaped (wrapper) toward the connecting portion between the bottom surface and the communication pipe 34. The inclined surface 33a is inclined downward.
With this configuration, all the water in the auxiliary container 33 can be discharged into the water tank 31 simply by opening the lid 5 of the heating cooker 1 after cooking.

Embodiment 3 FIG.
FIG. 7 is a cross-sectional view showing a steam treatment apparatus according to the third embodiment.
In the first embodiment, the number of connecting pipes 20 is one. However, in the steam processing apparatus 30B of the third embodiment, a plurality of connecting pipes 20 are formed. Specifically, as shown in FIG. 7, on the bottom surface of the auxiliary container 33, a plurality (two in the figure) of communication pipes 41 extending from the bottom surface of the auxiliary container 33 into the water tank 31, separately from the connection pipe 20, 42 is provided.
By comprising in this way, a vapor | steam can disperse | distribute and can contact with water, the movement of the heat | fever required for dew condensation can be made quick, and the efficiency of a vapor | steam process can be improved.

  Further, the submerged heights of the lower end openings 34a, 41a, 42a of the respective communication pipes 34, 41, 42 may be the same height or different heights, but they communicate with the communication pipe 41 shown in FIG. When the height is the same as the pipe 34, the steam discharged from the communication pipes 41 and 34 may interfere with each other and the amount of contact with water may decrease. For this reason, it is desirable to change the height position like the communication pipe 42. By doing so, interference can be prevented and the efficiency of the steam treatment can be improved.

  Further, when the adjacent lower end opening 41a and lower end opening 34a, or the lower end opening 34a and lower end opening 42a are close to each other, the exhaust steam may interfere with each other as described above, and the amount of contact with water may decrease. For this reason, it is preferable that the distance is long, and the distance is at least larger than the diameter (or short side) of the lower end opening. Thereby, it is possible to prevent the discharged steam from interfering with each other, and it is possible to perform the steam treatment with high efficiency.

Embodiment 4 FIG.
FIG. 8 is a cross-sectional view showing a steam treatment apparatus according to the fourth embodiment.
The steam treatment apparatus 30C according to the fourth embodiment has a configuration similar to that of FIG. 3 according to the first embodiment, and further has an atmosphere release pipe 50 connected to the lower surface side of the tank cover 32. The air release pipe 50 is configured by a substantially U-shaped pipe having one end connected to the bottom surface of the auxiliary container 33, and the other end is a free end. The free end opening 50a is configured to be located at a distance L from the height position of the water level scale 35. After the cooking is completed, the inside of the heating container 2 is cooled and water is discharged from the lower end opening 34a of the communication pipe 34. When the water level in the water tank 31 is lowered to the position of the free end opening 50a, the heating container 2 is opened to the atmosphere, and the sucked water is prevented from flowing back into the heating cooker 1. belongs to. Note that, as shown by the dimension s in FIG. 8, the atmosphere release pipe 50 is configured such that the bent portion of the atmosphere release pipe 50 is located at a lower height position than the lower end opening 34 a of the communication pipe 34. The steam is positively released not from the atmosphere open pipe 50 but from the communication pipe 34 side.

Next, the operation of the air release pipe 50 will be described.
When the cooking is finished and the inside of the heating container 2 is cooled and the internal pressure is reduced, the pressure in the connecting pipe 20 and the auxiliary container 33 is similarly reduced, and the lower end opening 34a of the communication pipe 34 and the free end of the atmosphere opening pipe 50 are reduced. Water in the water tank 31 is sucked up from the opening 50 a and enters the auxiliary container 33. Thus, since the water in the water tank 31 is sucked up, the water level in the water tank 31 decreases.

  And if the water level in the water tank 31 falls to the height position of the free end opening 50a of the atmospheric open pipe 50, air begins to be sucked in place of water from the free end opening 50a of the atmospheric open pipe 50. When the suction is further advanced and the water in the atmosphere opening pipe 50 is completely sucked, the air sucked from the atmosphere opening pipe 50 flows into the auxiliary container 33 and the connecting pipe 20, and the inside of the heating container 2 is atmospheric pressure. Return to.

  FIG. 9 shows a state where the inside of the heating container 2 is cooled and the air release pipe 50 is acted after the cooking is finished, and water is hatched with a net pattern for explanation. As shown in FIG. 9, when air is sucked from the free end opening 50 a of the atmosphere release pipe 50, the atmosphere communication from the atmosphere release pipe 50 to the connecting pipe 20 is established. As a result, the suction of water from the lower end opening 34a of the communication pipe 34 is also stopped, and the water sucked up from the free end opening 50a of the atmosphere opening pipe 50 and flowing into the auxiliary container 33 is water from the lower end opening 34a of the communication pipe 34. It is returned to the tank 31.

  As described above, since the air release pipe 50 whose one end is connected to the bottom surface of the auxiliary container 33 and the other end is opened to the atmosphere is provided, the water in the water tank 31 is heated via the connecting pipe 20 after cooking. 2 can be prevented from getting wet with the cooked product.

  Further, by reducing the distance L from the free end opening 50a of the air release pipe 50, the auxiliary container 33 can be made smaller or unnecessary, and the steam processing device 30 can be made smaller.

  In the fourth embodiment, the configuration in which one of the plurality of communication pipes provided in the tank cover 32 is the atmosphere opening pipe 50 is shown and described. However, the communication pipe 34 is omitted in FIG. Only one atmosphere opening pipe 50 may be provided in 32. In this case, since the steam is ejected only from the atmosphere opening pipe 50, the free end opening 50a of the atmosphere opening pipe 50 must be positioned below the water level scale 35.

  Note that the air release pipe 50 is not limited to the U-shaped pipe as shown in FIG. 8, and one end is connected to the lower surface side of the tank cover 32 (specifically, the bottom surface of the auxiliary container 33), and the water tank is connected to the connection portion. Any tube may be used as long as it is lowered toward the inside 31 and then bent and extends upward (including obliquely upward), and the other end is opened to be a free end.
