Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a rice cooker with a steam processing function that is additionally equipped with a function of eliminating the generation of steam.

BACKGROUND OF THE INVENTION Conventionally, there has been no rice cooker with a function to eliminate the steam generated. However, a device has been considered that diffuses the discharged steam by blowing a large amount of air, making the steam that forms when the steam condenses invisible.

Problems to be Solved by the Invention In this way, in conventional rice cookers, the generated steam was directly discharged into the room from the steam vent, which caused a significant change in the environment of the ladle, causing discomfort, dirt and condensation in the room, etc. It was causing this. In addition, rice cookers are sometimes arranged on shelves to make effective use of space in a small room or to store them neatly, but this can cause water droplets to condense on the top surface above the rice cooker. In addition, there was a risk of burns from the hot steam coming out of the steam vents.

The present invention has been made to solve these conventional problems, and aims to prevent the discharged steam from going into the room, and to enable it to be neatly stored and used on a shelf or the like.

Means for Solving the Problems In order to achieve the above object, the problem solving means of the present invention is to arrange a heat exchanger and a fan vertically at the rear of the rice cooker main body, and to communicate the heat exchanger with the fan. The heat exchanger is installed in the ventilation passage, and the heat exchanger and the steam hole of the rice cooker body are connected by a flexible tube. In addition, an inverted U-shaped pipe is provided inside the lid of the rice cooker main body, one end opens at the top of the rice cooker, and the other end contacts a cylindrical connecting gasket provided on the upper frame of the rice cooker main body. A hose connected to this connection gasket extends into the rice cooker body, and the end of the hose is connected to the heat exchanger.

According to the above-described structure, the steam generated during cooking is sent to the heat exchanger through the flexible tube from the steam hole in the lid, but the steam inside the heat exchanger is sent from the fan through the ventilation passage. It is cooled by the cooling air and turned into water droplets. For this reason, steam does not escape from the rice cooker body.

In addition, by guiding the generated steam through the rice cooker body to the heat exchanger via the inverted U-shaped pipe, connecting gasket, and hose, there is no need to expose the steam introduction pipe to the outside of the rice cooker body. It will get better.

EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings. In FIGS. 1 and 2, 1 is a rice cooker main body, which has a lid 2 on the top that can be opened and closed and is pivoted on the upper end of the main body 1 with a hinge 1a, and an inner lid 3 on the bottom of the lid 2. ing. The inside of the main body 1 has a rice cooking chamber 4 formed by a protective frame 4a, and a rice cooking heater 6 and a temperature sensor 7 are arranged in the lower part of the rice cooking chamber 4. Heating and temperature control are performed.

At the rear of the main body 1 (below the hinge 1a), a heat exchanger 8 and a fan 9 are vertically arranged as shown in FIG.
It is set within 0. The heat exchanger 8 includes a heat exchange pipe 11 and a fin 12 that penetrates and holds the heat exchange pipe 11 to radiate heat from the heat exchange pipe 11.
and passage members 13 that hold the fins 12 and form passages for steam and condensed water on both sides. The lower part of the passage member 13 has a drain hole 14 for dripping condensed water, and a drain container 15 for receiving the dripped water is removably installed below the drain hole 14 . A ventilation passage 16 is formed on the back side of the heat exchanger 8 and communicates with a ventilation case of a fan 9 driven by a motor 18 disposed below. Reference numeral 17 denotes a louver provided in the ventilation passage 16 on the back side of the heat exchanger 8.

Further, 10a is an inlet for sucking cold air through the rotation of the fan 9, and 10b is an outlet for air that has passed through the heat exchanger 8.

One end of a flexible tube 20 is connected to the inlet of the heat exchange pipe 11, and the other end is connected to a steam hole 21 provided through the lid 2 through the upper surface of the cover 10.

In addition, 22 is a lock button when closing the lid 2 and main body 1.
When the lid 2 is locked, the steam generated in the rice cooker 5 does not leak from the main body 1.

In the above configuration, steam generated in the rice cooking pot 5 by heating by the rice cooking heater 6 passes through the inner lid 3, the steam hole 21, flows into the inlet part of the heat exchange pipe 11 through the flexible tube 20, and further flows into the heat exchange pipe 11. flows in the direction of the arrow shown in FIG. 2 and reaches the outlet section below. At this time, the steam in the heat exchange pipe 11 has its heat removed by the cooling air blown from the ventilation passage 16 by the fan 9, becomes condensed water, and drips into the drain container 15 from the drain hole 14. Note that the cooling air sucked in from the intake port 10a by the fan 9 is sent to the ventilation passage 16.
When flowing inside, it is bent toward the heat exchanger 8 by the louvers 17, and moreover, it is made to uniformly hit the entire surface of the heat exchanger 8.

In this way, by passing all the steam generated from the rice cooker 5 through the flexible tube 20 and turning it into water droplets via the heat exchanger 8, no steam builds up around the main body 1, improving the indoor environment.

Next, another embodiment will be described with reference to FIG. The difference from the above embodiment is that instead of the flexible tube 20 exposed to the outside, an inverted U-shaped 17) pipe 23 and a hose 25 are connected with a connecting parakin 24 and arranged inside the rice cooker. This is the point.

That is, an inverted U-shaped pipe 23 is provided inside the lid 2A, one end facing the inner lid 3 on the rice cooking pot 5, and the other end facing the upper frame of the upper surface of the main body 1 near the upper hinge 1a of the main body 1. It is connected to a cylindrical connecting gasket 24 provided at 24b. The connecting gasket 24 and the inlet of the heat exchanger 10 are connected by an L-shaped hose 25 provided inside the main body 1.

In the above structure, when the lid 2A is closed, the other end of the pipe 23 and the upper part of the connecting gasket 24 are connected in an airtight manner, and when the lid 2A is opened, the other end is detached. Therefore, during cooking, steam from the rice cooker 5 flows through the pipe 23 and the hose 2.
5, flows into the heat exchanger 8, becomes water droplets by the same cooling effect as described above, and is collected in the drain container 15.

By connecting the pipe 23 and the hose 25 within the main body 1 through the connection gasket 24 in this manner, the connected parts are not exposed, resulting in a clean appearance.

Effects of the Invention As is clear from the above explanation, in the rice cooker with steam processing function of the present invention, the steam in the rice cooker is guided through the lid to the heat exchanger with a flexible tube and turned into water droplets. will no longer be discharged into the room. This eliminates the problem of steam causing a significant change in the indoor environment, discomfort, indoor dirt, and condensation, and eliminates water droplets on the top surface above the rice cooker even when the rice cooker is stored on a shelf. No more condensation. For this reason, it can also be used as a built-in rice cooker, making it possible to neatly store the rice cooker that was previously placed on the countertop in the kitchen. Furthermore, since hot steam does not come out from the exhaust hole, there is no danger of people being burned by the steam, improving the safety of the device.

In addition, the connection parts for introducing steam are not exposed outside the rice cooker main body, resulting in a cleaner appearance, and there is no need to consider the durability of the flexible tube against opening and closing of the lid, making it easier to maintain quality.
