That is, a rice cooking pot 42 is housed in the device main body 41, and a lid 43 is attached to the upper part of the device main body 41 by a support shaft 44 so as to be openable and closable. This lid body 43 is provided with a steam exhaust port 45 for discharging steam generated from the rice cooking pot 42 to the outside of the device main body 41. In this configuration, when rice and water are placed in the rice cooker 42 and heated by the heating element 46 to cook rice, the water inside the rice cooker 42 boils and steam is generated. This steam is discharged from the discharge port 45.

Problems to be Solved by the Invention However, with this configuration, the emitted steam is at a high temperature, so if the user accidentally comes into contact with the steam, there is a risk of burns, etc., and there is a safety problem. It was hot. Furthermore, since the steam is blown upwards, other items cannot be placed above the rice cooker, and a large space is required when cooking rice. Also, if the rice cooker is installed near a wall, the steam may condense on the wall. However, there were problems with the installation location, such as damaging the wall surface, and making it difficult to use. Additionally, since the heating element becomes extremely hot during rice cooking, there was a problem in that a sufficient heat shielding structure was required in order to place electronic components that are sensitive to high temperatures, that is, the control circuit section, inside the main body of the device. .

Therefore, an object of the present invention is to provide a rice cooking device that can solve the above problems.

It is attached so that it can be opened and closed, and a heating element is arranged at the inner bottom of the rice cooker storage chamber, and one end is opened to the front of the device main body and the other end is opened to the front of the device main body at a position below the rice cooker storage chamber of the device main body. A ventilation passage opened at the top of the air passage is provided, and a ventilation means is provided in the middle of this ventilation passage,
The lid is provided with an exhaust passage whose one end is opened opposite to the opening at the other end of the ventilation passage and whose other end is opened in the front of the lid, and a steam exhaust port provided in the lid is provided. A control circuit unit connected to the exhaust passage and controlling the heating element is disposed within the ventilation passage.

Function According to the above configuration, steam generated during rice cooking enters the exhaust passage through the steam outlet, where it is mixed with air and discharged to the outside as low-temperature, moist air. Therefore, even if the user accidentally touches the air outlet, there is no danger of burns or the like. Also,
The control circuit section disposed within the ventilation passage is protected from heat from the heating element by the air flowing within the ventilation passage.

Embodiment Hereinafter, an embodiment of the present invention will be described based on FIGS. 1 to 4.

Reference numeral 1 denotes a device main body of a rice cooking device 3 which is inserted into a storage shelf 2 so as to be freely drawn out, and inside thereof there is a storage chamber 5 (hereinafter referred to as a pot storage chamber) for a rice cooker 4 which is open at the top and is separated by a partition wall 6. At the same time, a heating element 7 and a rice cooking pot 4 are installed at the inner bottom of the pot storage chamber 5.
A pot sensor 8 is arranged to detect the temperature at the bottom of the pot. A partition wall 6 forming the pot storage chamber 5
A ventilation passage 9 is formed between and the outer wall portion 1a of the device main body 1, one end of which is opened below the front panel portion 1b of the device main body 1, and the other end of which is opened to the rear upper surface. Further, a blower (air blowing means) 12 consisting of a fan 10 and a motor 11 is arranged in the middle of the blow passage 9. An air filter 14 is attached to the opening at one end of the ventilation passage 9, that is, the intake port 13, and the opening at the other end, that is, the exhaust port 15 is attached to the upper frame portion 1 of the device main body 1.
It is formed in c. Upper frame portion 1 of the device main body 1
A lid 16 for opening and closing the upper end opening of the pot storage chamber 5 is supported via a support shaft 17 on the rear upper surface of a. A horizontal partition wall 18 is disposed inside the lid 16, and a space above the partition wall 18 is an exhaust passage 19. One end of this exhaust passage 19 is opened as a suction port 20 at a position opposite to the exhaust port 15 of the ventilation passage 19, and the other end is opened as an air outlet 21 in the front surface of the lid body 16. Note that a portion of the upper wall portion of the lid body 16 is a removable cover 22. In addition, the lid body 1
The space below 6 is filled with a heat insulating material 23, and a heat sink 24 made of a material with high thermal conductivity (for example, an aluminum plate) is provided on the bottom wall. On the surface is a temperature detector (temperature detection means) 2 for detecting the steam temperature in the pot storage chamber 5.
5 is placed. The temperature detector 25 is configured to close the contact when the temperature exceeds a predetermined temperature, and open the contact when the temperature becomes lower than the predetermined temperature.
It is electrically connected to the motor 11 of the blower 12. That is, when the contacts are closed, the motor 11 is activated and the fan 10 is rotated. Furthermore, a steam outlet 26 is formed in the lid 16 to take out the steam generated in the pot storage chamber 5, and this steam outlet 26 is connected to the exhaust passage 19. 27 is a switch operation section installed on the front panel section 1b of the main body 1, and 28 is a switch operation section 27.
This is a control circuit section that controls the power supply to the heating element 7 based on the signal. This control circuit section 27 is arranged inside the ventilation passage 9 so as to create a space 29 for ventilation between it and the heating element 7. Note that the pot sensor 8 is also electrically connected to the control circuit section 27.

Next, the operation of the rice cooking device will be explained.

First, place the rice cooking pot 4 containing rice and water on top of the heating element 7 in the pot storage chamber 5 of the device main body 1, and then cover it.
Rice cooking is started using the switch operation section 27. When the switch is turned on, the heating element 7 is
The heating element 7 is heated, the water temperature inside the rice cooker 4 rises, and steam is generated. When the temperature of the heat sink 24 rises due to the steam and reaches a predetermined temperature or higher, the temperature detector 25 is activated, and the blower 12 is activated in response to the signal. The blower 12 sucks outside air through an air filter 14 from an intake port 13 provided at the lower front of the main body 1 of the apparatus. The sucked air passes through the upper space 29 of the control circuit section 28, absorbs heat from the heating element 7, and is discharged from the exhaust port 15 to the lid body 1.
6 into the exhaust passage 19. On the other hand, steam generated during rice cooking enters the exhaust passage 19 from the steam outlet 26, mixes with the outside air flowing through the exhaust passage 19, becomes low-temperature steam, and is discharged forward from the outlet 21. The emitted steam is at a low temperature, so there is no risk of getting burned if you come into contact with it. Additionally, as rice cooking progresses and the water in the rice cooker 4 evaporates, the internal temperature of the rice cooker 4 rises, the pot sensor 8 detects this temperature, and when the temperature reaches a predetermined value, power supply to the heating element 7 is stopped. Then, cooking is completed. Furthermore, when the steam inside the rice cooker 4 runs out, the temperature of the heat sink 24 gradually decreases, and when the temperature drops below a predetermined temperature, the contact of the temperature detector 25 opens, and the blower 12 is stopped by that signal. . Note that even if the lid 16 is opened while steam is being generated, the heat sink 2
4 decreases, and the blower 12 is also stopped.

Effects of the Invention According to the above configuration of the present invention, since the steam exhaust port is connected to the exhaust passage provided in the lid, the steam generated during rice cooking is mixed with the air flowing in the exhaust passage.
It can be dispersed and discharged outside the rice cooker as low-temperature, humid air, so there is no danger of burns or the like even if the user accidentally touches the vicinity of the air outlet. In addition, by discharging steam to the front of the rice cooker, the space above the rice cooker can be used effectively, and by exhausting the steam as dispersed moist air, condensation on walls near the rice cooker can be prevented. It can be prevented. Furthermore, since the control circuit section is disposed within the ventilation passage, heat from the heating element is absorbed by the air flowing within the ventilation passage, and therefore the control circuit section is protected from heat.
