[Problems to be solved by the invention]
In the conventional configuration described above, the ratio of the storage 51 in the kitchen is high, and the cooking utensil 54 itself has changed in size, shape, heating means, and the like, and has problems such as difficulty in storage. Moreover, since the cooling structure is not used, air containing steam is discharged from the discharge port, and there is a problem that sufficient steam treatment is not performed. The actual situation is that the exhaust fan and the range hood are far away from each other and have not yet reached the point where steam is processed. Also, by installing a steam guide at the steam outlet of the electric rice cooker and attaching it, the moisture of the steam can be condensed and removed by the cooling formation part, but the steam guide is steamed every time rice is cooked. There is inconvenience to install at the exit, and it is necessary to use a dedicated electric rice cooker for installation.
[0006]
This invention solves the said subject, does not require the three-dimensional place from a floor surface like the storage 51, and does not need to equip an electric rice cooker with a steam guide for every rice cooking. In addition, the steam is sucked from the steam suction port 7a, and the steam is cooled by the cooling forming unit 14 so as to prevent the condensation on the surface of the surrounding kitchen by lowering the condensation temperature or less, and from the jar rice cooker or the jar pot. The purpose is to prevent vapor from leaking to the surroundings and condensing by exhaust from an exhaust port around the steam port.

[0011]
Moreover, FIG. 2 attaches the cover 24, the steam guide 7, and the filter 8 to FIG. 1, and the electric rice cooker 1 and the system kitchen can be seen in the A1-A2-A3-A4 cross-sectional arrow view. It is sectional drawing which added the counter-2, the hanging cupboard 3, and the wall surface 4 partially.
[0012]
3 is a bottom view of the cover 24, the steam guide 7, and the filter 8 as viewed from below in FIG. 1, and FIG. 4 is a cross-sectional view of the current detection unit used in the present invention. FIG. 5 is a circuit diagram of the present invention.
[0013]
As shown in FIG. 2, the steam processing unit is a top surface portion, is attached to the hanging cupboard 3, and the steam outlet of the electric rice cooker 1 is placed just below the steam suction port 7 a of the steam processing unit on the counter 2 of the kitchen. Use in place. As shown in FIGS. 1 and 2, the external appearance is shaped by the top plate 5, the back plate 6, and the cover 24. The top plate 5 and the back plate 6 are made of iron plate or the like, and form the base of the steam processing unit. The steam guide 7 has a cylindrical shape and has a steam suction port 7a near the top. The filter 8 has a small hole or mesh so as not to inhale small flying insects. The steam guide 7 is detachably attached to the cover 24 so that it can be easily maintained. By attaching the steam guide 7, it is connected to the inlet of the introduction pipe 9. The outlet of the introduction pipe 9 is connected to a wind tunnel 10, and the wind tunnel 10 has a fan 11 and a motor 12 for rotating the fan 11. The wind tunnel 10 is attached to the back plate 6 with screws or the like.
[0014]
The connection part A13 is connected to the outlet of the wind tunnel 10. One end of the connection part A13 is connected to the cooling formation part 14, the outlet of the cooling formation part 14 is connected to the connection part B16, and one end of the connection part B16 is connected to the guide pipe 17. The outlet of the guide pipe 17 is connected to the connection part C18. The connection part C18 is formed in a trident, and the outlet is connected to the dew receiving guide 19 and the discharge pipe 21. The dew receiving guide 19 guides water to the dew receiver 20 and stores water in the dew receiver 20 when dew condensation is generated when steam and air flow. The outlet of the discharge pipe 21 is connected to the discharge passage 22, the passage is formed around the steam suction port 7 a, and the discharge port 23 is formed around the steam suction port 7 a similarly to the discharge passage 22. It is comprised so that a vapor | steam and air may be discharged | emitted toward it.
[0015]
Moreover, by making the cooling formation part 14, the guide pipe 17, and the discharge pipe 21 into a metal, a vapor | steam and air can be cooled more. The connecting parts A13, B16, C18 are usually made of elastic rubber. The outlet 23 may be provided with an outlet filter so that insects such as squirts do not enter. In order to positively remove moisture contained in the steam and air, a cooler 15 is attached to the outside of the lower surface of the cooling forming portion 14, and the surface thereof is configured to substantially face the flow of steam and air. As the cooler 15, a compressor, a cooling element using the Peltier effect, or the like is used. By insulating the cooling surface of the cooler 15 and the outside of the cooling formation portion 14, a configuration that enhances the cooling of the cooling formation portion 14 can be simplified. Moreover, the recovery rate of moisture contained in the steam can be increased by partially using a metal with good heat dissipation in the introduction pipe 9 and performing heat dissipation of the cooler 15 in that portion.
[0016]
Reference numeral 25 denotes an outlet, which is a power source for the electric rice cooker 1. Reference numeral 26 denotes a current detection unit for automatically turning on and off the motor 12 according to the current of the electric rice cooker 1 and rotating or stopping the rotation of the fan 11. As shown in the sectional view of FIG. 4, the current detection unit 26 includes a current detection resistor 30, a thermostat 31, a current detection unit assembly base 32, an insulating plate 33, a heat storage plate 34, a thermostat mounting plate 35, and a heat insulating cover. -36, lead wire 37, current detection resistance set screw 38, current detection unit mounting plate 39, current detection unit set screw 40, and the like.
[0017]
Here, the thermostat 31 is of a type in which the contact is turned off at room temperature and turned on when the temperature rises. A switch 27 is an ON-OFF-ON switch characteristic having an OFF point at an intermediate point. By using the outlet 25 as a power source of the electric rice cooker 1, a fan corresponding to the magnitude of the current flowing through the current detection resistor 30 is used. The automatic circuit that automatically turns 11 and stops, the circuit that always turns the fan 11, and the OFF circuit can be manually switched. A neon lamp 28 lights up and displays that the switch 27 is in the circuit in which the fan 11 rotates. Reference numeral 29 denotes a stable resistance of the neon lamp 28. In order to prevent malfunction when the automatic circuit of the fan 11 is configured, three resistors having a resistance value of 50 kΩ are used in the case of a 100 V power supply.
[0018]
In the above configuration, as an example, the power of the electric rice cooker 1 is obtained from the outlet 25, the switch 27 is set to an automatic circuit, the electric rice cooker 1 is placed almost directly below the steam suction port 7a of the steam guide 7, and rice cooking is started. To do. When the current starts to flow, the current detection resistor 30 generates heat. When the thermostat 31 reaches the operating temperature, the contact point of the thermostat 31 is turned on, the motor 12 rotates and the motor 12 is attached. The fan 11 attached to the shaft rotates. The fan 11 is placed so as to rotate in the suction direction in advance. The thermostat 31 is always OFF and is turned ON when the temperature rises. Usually, an ON temperature is around 75 ° C. and an OFF temperature is around 55 ° C. Although the heat generation of the current detection resistor 30 varies depending on the current, the time until the thermostat 31 after the rice is cooked by the heat storage plate at the reached temperature of about 130 ° C. can be changed.
[0019]
Here, when the water and rice in the electric rice cooker 1 reach the boiling point, the steam is discharged from the steam port of the electric rice cooker 1. The steam rises and reaches the steam suction port 7 a of the cylindrical steam guide 7. Since the fan 11 rotates in the suction direction, the steam is sucked into the introduction pipe 9 together with air. The sucked steam and air are formed around the steam suction port 7a through the wind tunnel 10, the connection part A13, the cooling formation part 14, the connection part B16, the guide pipe 17, the connection part C18, the exhaust pipe 21, and the exhaust passage 22. It is exhausted from the exhaust port 23 so that steam from the electric rice cooker 1 does not escape to the outside. In this flow of steam and air, touch a part that is lower than the steam temperature, and if that part is below the condensation temperature, condensation occurs, and the moisture contained in the steam becomes water, and the lower part along the slope It flows in the direction and passes through the dew receiving guide 19 and is stored in the dew receiving 20.
[0020]
Steam and air are cooled by the cooling forming part 14, the guide pipe 17, and the discharge pipe 21 that use a metal having a large heat dissipation effect, so that the exhaust is discharged below the dew condensation temperature with respect to the temperature of the wall surface 4, the ceiling, and the hanging cabinet 3 of the kitchen. It can be done.
[0021]
When rice cooking is completed and the current decreases, the current detection resistor 30 generates less heat, the temperature of the thermostat 31 decreases, and when the temperature reaches the OFF temperature, the contact opens and the motor 12 stops rotating and the fan 11 rotates. Also stops.
[0022]
At the time of heat insulation, the heat generation of the current detection resistor 30 with the heat insulation current may be set to be equal to or lower than the OFF temperature of the thermostat 31. In terms of design, the current detection unit 26 can be obtained with a simple configuration and at low cost by determining the resistance value of the current detection resistor 30 so that the temperature around 1.5 amperes is below the OFF temperature of the thermostat 31. It is. When it is desired to treat the moisture regardless of the current of the outlet 25, the switch 27 is always turned on so that the fan 11 is always rotating in the direction of sucking air. After the part A17, if the temperature of the cooling formation unit 14 is set below the condensation temperature with respect to the temperature of the air by the cooler 15, moisture in the air is condensed and removed as water, and dehumidification in the kitchen is performed. It can be done. The cooler 15 may be operated so as to operate in conjunction with the fan 11. The neon lamp 28 is lit regardless of the rotation of the fan 11 when the switch 27 is placed in the ON direction.
[0023]
According to the present embodiment, the electric rice cooker 1 and the electric jarpot are used by being placed almost directly under the steam suction port 7a of the cylindrical steam guide 8 and thereby coming out of the electric rice cooker 1 and the electric jarpot. The rotation of the motor 12 is transmitted to the fan 11 and is sucked together with the air through the steam suction port 7a by rotating in the direction of suction, and the introduction pipe 9, the wind tunnel 10, the connecting part A13, the cooling forming portion 14, It is discharged from the discharge port 23 around the steam port 7a through the connection component B16, the guide pipe 17, the connection component C18, the discharge pipe 21, and the discharge passage 22.
[0024]
Since the cooling forming portion 14, the guide pipe 17, and the discharge pipe 21 are made of metal such as aluminum having a high heat dissipation effect, the discharged steam and air are discharged from the discharge port 23 at a temperature about 2-3 ° C. higher than the room temperature. Since the steam temperature from the electric rice cooker 1 is lower than when the steam processing unit is not used, it is difficult for condensation to occur on the wall 4 of the kitchen, the ceiling, the hanging cupboard 3 and the like. Usually, when the distance between the top of the hanging cupboard 3 and the top of the electric rice cooker 1 is 35 cm and rice is cooked, dew condensation is seen on the bottom and front of the hanging cupboard 3, but the steam suction port 7a of the steam processing unit and the electric rice cooker 1 When the rice was cooked at a distance of 35 cm, no condensation occurred on the bottom surface and front surface of the hanging cabinet 3.
[0025]
When the steam treatment unit is not used under the same conditions as described above, cooking may occur at the kitchen ceiling by cooking at a humidity of 80% or more in the kitchen. However, when the steam treatment unit is used, the kitchen ceiling Also, no condensation occurred. By providing the discharge port 23 around the steam suction port 7a, the air volume of the fan 11 was 1.5 m3 / min in the above test, and the diffusion of steam from the electric rice cooker 1 could be prevented. When the discharge port 23 is not located around the vapor suction port 7a but is formed on the upper front surface, a slight escape was recognized even when the fan 11 having an air volume of 2 m3 / min was used.
[0026]
As can be seen from the above test results, since the fan 11 with a small air volume can be used, noise reduction and energy saving can be obtained, and the outer dimensions of the product can be made compact. With the above configuration, a well-balanced steam processing unit with a small installation volume can be obtained, and the installation location is mounted using the lower surface of the hanging cabinet 3 so that a relatively unused space is used, so that installation is not accompanied by exhaust work. As a total cost, an inexpensive steam discharge unit can be obtained.
[0027]
Further, when the cooler 15 is attached to the cooling forming unit 14, the cooling forming unit 14 can be made more compact, and air can be discharged at a temperature lower than room temperature depending on the ability of the cooler 15, so that the kitchen cabinet 3 In addition, it was possible to prevent condensation on the ceiling and to recover 20% of the water discharged from the electric rice cooker 1 under the above test conditions during cooking. Moreover, by using as a dehumidifier, the water | moisture splashed in the kitchen can be collect | recovered, humidity falls and the comfortable kitchen room environment is obtained.
[0028]
As mentioned above, it is not necessary to attach a steam guide to the steam outlet of the rice cooker every time it is cooked, it does not require a dedicated electric rice cooker, and can be used for a wide range of electric rice cookers. It has the convenience that can respond to.
[0029]
By installing the steam treatment unit in this way, the temperature of the steam and air is lowered and discharged, so that the hanging cabinet 3, the ceiling of the kitchen room, and the wall 4 can be prevented from getting wet due to condensation. It can also prevent damage caused by heat, condensation. In this way, it is possible to realize a comfortable kitchen room environment with low humidity compared to the conventional one because it can be used in a wide range with a simple configuration, low cost installation volume and high performance and easy to use steam processing unit. It is.
