Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a rice cooking device that cooks rice and keeps it warm while the rice cooker is housed.

Conventional technology This type of conventional rice cooking device is, for example,
As shown in No. 33737, it had the structure shown in Figure 3.

That is, when rice and water are put in the rice cooker pot 1 and rice is cooked by heating the rice cooker pot 1 with the heating device 2, steam is released from the gap between the lid 3 and the rice cooker pot 1 into the rice cooker storage 4.
Come out inside. The steam filling the rice cooker storage 4 is discharged from the exhaust port 5 and the exhaust port 6. The steam discharged from the exhaust port 6 is passed through the exhaust passage 7.
and is discharged to the outside of the main body 1 from the external exhaust port 8.

Problems to be Solved by the Invention However, with such a structure, the steam exhausted is high temperature, so if the user accidentally comes into contact with the steam, there is a risk of burns, etc., and there are safety issues. It was hot. Furthermore, there was a drawback that steam condensed on the inner wall of the rice cooker storage and the inner wall of the opening/closing door, causing water droplets to adhere and easily corrode.

Therefore, the present invention aims to reduce the temperature of the steam generated during rice cooking and discharge it outside the main body to prevent dew condensation on the main body of the device.

Means for Solving the Problems In order to solve the above problems, the present invention includes an air blowing means and an exhaust passage in the main body of the apparatus, and the exhaust passage has an air passage through which air sent from the air blowing means flows, and an air passage through which the air sent from the air blowing means flows. It is divided into a steam passage through which air flows and a mixing chamber where air and steam are mixed, via a heat sink, and the mixing chamber is widened toward the end in the direction of air flow.

Effect The effect of this technical means is as follows.
The steam generated from the stored rice cooker is led to the steam passage, where the heat is exchanged with the air flowing through the air passage by a heat radiating plate, resulting in a low temperature.The steam is then mixed with air in the mixing chamber and exhausted to the outside of the main unit. At this time, since the mixing chamber widens toward the end in the flow direction, resistance in the flow direction is low and steam does not flow backwards.

As a result, the steam generated from the rice cooker is exhausted outside the main body as low-temperature air, and furthermore, the steam does not flow back into the main body.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. In Figures 1 and 2, 21
2 is a rice cooker body, 22 is a rice cooker detachably provided in the rice cooker body 21, 23 is an exhaust passage provided above the rice cooker 22, and an electric motor 24 and a fan 25 are provided as air blowing means. It is being 26 is a steam exhaust port connected to the exhaust passage 23 and provided at the front of the rice cooker main body 21.

Reference numeral 27 denotes a heat sink provided in the exhaust passage 23, which divides the exhaust passage 23 into an air passage A and a steam passage B, and provides a mixing chamber C between it and the steam exhaust port 26. This mixing chamber C is widened toward the end of the steam exhaust port 26 side. Reference numeral 28 indicates an intake port provided at the lower front part of the rice cooker main body 21, and 29 indicates an intake port 28.
This is a passageway that guides the air led from the exhaust passageway 23 to the exhaust passageway 23. 30 is a drawer in which the rice cooker 22 can be installed in a detachable manner, and 31 is a steam outlet provided on the top surface of the rice cooker 22. Reference numeral 32 designates a steam inlet that is provided in the steam passage B and is located opposite to the steam outlet 31, and 33 is a temperature detection device that is provided near the steam inlet 32.

34 is a storage section that stores the rice cooker 22;
Reference numeral 5 denotes a storage space provided below the storage section 32 in which various items can be placed. 36 is a door that covers the front of the storage section 34 and the storage 35. 37 is a see-through window provided in the door 36, and the switch part 3 of the rice cooker 22
Corresponds to 8.

The operation of the rice cooking device configured as described above will be explained below.

Rice and water are put into the rice cooker 22 and rice cooking is started. After a while, steam is generated from the steam outlet 31, passes through the steam inlet 32, and is guided into the steam passage B. At this time, when the steam contacts the temperature detection device 33 and reaches a certain temperature or higher, the electric motor 24 operates and the fan 25 rotates. Therefore, the intake port 28
Air is sucked in from the air, passes through the passage 29, passes from the air passage A through the mixing chamber C, and is exhausted from the steam exhaust port 26, creating an air flow, and the steam led into the steam passage B from the steam inlet 32 releases heat. After exchanging heat with this air through the plate 27 and lowering the temperature, the air is mixed with the air flow in the mixing chamber C and discharged to the outside of the main body 21 of the apparatus. The mixing chamber C has a shape that widens toward the steam exhaust port 26 side, and since the resistance is small, air always flows toward the steam exhaust port side and does not flow back into the steam passage B. When the rice cooking is completed, the steam outlet 31
When the steam generation from the motor 24 stops and the temperature detected by the temperature detection device 33 decreases to below a certain temperature, the electric motor 24
operation will be stopped.

Effects of the Invention The present invention includes an air blowing means and an exhaust passage within the device body, and the exhaust passage is divided by a heat sink into an air passage, a steam passage, and a mixing chamber where air and steam are mixed. Since the mixing chamber is widened toward the end in the direction of air flow, the steam generated during rice cooking can be disposed of as a low temperature, and the steam can be prevented from flowing back into the main body of the device.
