Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a rice cooking device capable of lowering exhaust temperature during rice cooking.

BACKGROUND ART A conventional rice cooking device of this type has a structure as shown in FIG. 3, for example.

That is, the pot 2 was housed in the device main body 1, and the lid 3 was pivotally supported on the upper part of the device main body 1 via a hinge 4 on one side of the device main body 1. The lid 3 is provided with a steam passage chamber 5 for discharging the steam generated from the pot 2 to the outside of the device main body 1, and has a structure in which the steam is discharged from the steam outlet hole 6 to the outside of the device main body 1.
That is, when rice and water are placed in the pot 2 and heated to cook, the water in the pot 2 boils and steam is generated.
This steam passes through the steam passage chamber 5 and is discharged from the steam outlet hole 6.

Problems to be Solved by the Invention However, the problem with conventional structures such as this is that because the steam emitted is high temperature, there is a risk of burns if the user accidentally comes into contact with the steam. It was hot. Furthermore, when installed near a wall, steam condenses on the wall surface and damages the wall surface, limiting the installation location and making it difficult to use.

Therefore, the present inventors developed a rice cooking device that includes an exhaust passage in the lid for exhausting steam, and a blower device that blows indoor air into the exhaust passage.
However, even in this case, if the blower malfunctions,
The temperature inside the exhaust passage rose and the steam being discharged became so hot that there was a risk of burns.

The present invention is intended to solve these problems, and aims to provide a rice cooking device that does not emit high-temperature steam by stopping rice cooking when the blower device malfunctions. .

Means for Solving the Problems In order to solve the above-mentioned conventional problems, the rice cooking device of the present invention is provided with an exhaust passage inside the lid through which steam generated from the main body of the device passes, and also blows air into this exhaust passage. In addition, a temperature detection means is provided inside the exhaust passage, and a means for stopping rice cooking using the temperature detection means is provided.

Effect With the above configuration, the steam generated during rice cooking is guided to the exhaust passage inside the lid, and mixed with the indoor air by the blower inside the exhaust passage. Part of the steam condenses in the exhaust passage, and the remaining The steam is discharged at a lower temperature.

If the blower does not operate for some reason, the exhaust passage is filled with high-temperature steam, increasing the temperature within the exhaust passage. This temperature increase causes
The temperature detection means detects that the air blowing means is stopped, and the rice cooking operation is stopped. Therefore, high-temperature steam is not discharged, making it very safe.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In FIGS. 1 and 2, reference numeral 11 denotes a rice cooking section of the main body of the apparatus whose top surface is open, and the top surface of this rice cooking section 11 is formed by an upper frame 12.

A heating element 13 is provided in the rice cooking section 11, and a pot 14 is detachably attached to the upper part of the heating element 13. The outer surface of the rice cooking section 11 is made up of a body 15, provided with ventilation holes 15a and 15b, and the opening surface of the rice cooking section 11 is covered with a lid 16.
This lid 16 is provided with an inner lid 17 that covers the upper surface of the pot 14, and this inner lid 17 is provided with a hole 17a through which steam passes. The lid 16 is pivotally supported on one side of the rice cooking section 11 via a hinge section 18, and a hook section 19 is provided on the opposite side of the hinge section 18. Further, an exhaust passage 20 is provided in the lid 16, and one end of the exhaust passage 20 opens to the front as an exhaust port 21, and the other end opens to the rear of the rice cooking section 11 as an intake port 22. The lid 16 is provided with a steam guide 23 that communicates the exhaust passage 20 with the pot 14.
Steam generated within the pot 14 is guided to an exhaust passage 20. Furthermore, a blower device 24 is provided in the exhaust passage 20 and is arranged closer to the intake port 22 than the steam guide 23 is.

A temperature fuse 25 forming a series circuit with the heating element 13 is provided on the upper wall of the exhaust passage 20 on the side closer to the blower 24 than the steam guide 23, and this temperature fuse 25 melts when it reaches a certain temperature. It functions as a temperature detection means and stops power supply to the heating element 13.

Further, a pot sensor 26 for detecting the temperature of the bottom of the pot 13 is provided at the bottom of the rice cooking section 11, a heat insulating material 27 is arranged around the inner periphery of the rice cooking section 11, and a switch operation section 28 is provided at the front. There is. And rice cooking part 11
is stored in the cabinet 29 in a drawer manner using a slide rail 30 and a handle 31. In addition, 32 is an insect repellent packing.

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

The rice cooking section 11 is pulled out from the cabinet 29 by pulling the handle 31 toward you. Therefore, by releasing the hook part 19 and opening the lid 16 with the hinge part 18 as the supporting shaft, the upper surface of the pot 14 is opened, so that the pot 14 can be attached or removed. When storing the rice cooking section 11, the operation can be performed in the opposite manner.

To cook rice, put rice and water in the pot 14 and turn on the switch operating section 28. Then, power is supplied to the heating element 13 and the blower device 24 is operated. The blower device 24 generates an air flow in the exhaust passage 20 that takes in air from the intake port 22 and exhausts it to the exhaust port 21 . The water in the pot 14 heated by the heating element 13 turns into steam, passes through the hole 17a of the inner lid 17, and is guided into the exhaust passage 20 by the steam guide 23. Here, the steam is mixed with air by the blower 24, becomes low temperature, and is exhausted from the exhaust port 21. At this time, the temperature fuse 25 does not come into contact with steam due to the air flow, so it can always maintain a low temperature.

Then, as the rice cooking progresses and the water in the pot 14 evaporates, the bottom temperature of the pot 14 rises, the pot sensor 26 detects this temperature, and when the temperature reaches a predetermined value, power supply to the heating element 13 is stopped. The blower device 24 automatically stops after a certain period of time after the end of rice cooking in order to discharge steam due to residual heat.

Next, a case where the blower device 24 does not operate due to a failure will be described. When the blower device 24 does not operate, no air flow occurs in the exhaust passage 20 from the intake port 22 to the exhaust port 21. When steam is introduced into the exhaust passage 20, it stagnates on the upper wall of the exhaust passage 20. Then, when the temperature fuse 25 comes into contact with the steam, the temperature rises, and exceeds a certain temperature, it is fused and the power supply to the heating element 13 is stopped, so that the generation of steam can be stopped. Therefore,
The steam is not discharged from the exhaust port 21 while remaining at a high temperature, and it is possible to prevent accidental burns as in the conventional case.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, the steam generated during rice cooking is mixed with air by the exhaust passage and air blower provided in the lid of the rice cooker, and the temperature is lowered. It can be dispersed and exhausted to the outside of the rice cooker main body as low-temperature air. Even if cooling air is not flowing through the exhaust passage due to a failure of the blower, the temperature detection means provided in the exhaust passage will detect the failure due to an increase in temperature.
Stop the rice cooking operation. Therefore, high-temperature steam is not discharged outside the main body of the apparatus.

As a result, there is no risk of burns as with conventional methods, and since the temperature of the steam is low, it is difficult for steam to condense on walls, etc., making it easy to use and safe as it is less susceptible to installation location restrictions. This is what we provide.
