Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a rice cooker, and more specifically to the structure of a steam venting device for a rice cooker.

(Prior art) A steam release device in a conventional rice cooker communicates the inside of the pot housed in the rice cooker body with outside air by penetrating the outer cover and the inner cover of a cover unit having an outer cover and a pot cover, respectively. However, in this conventional steam venting device, when the steam generated in the pot during rice cooking is released into the outside air through the steam venting passage, the droplets contained in the steam are released. There was a problem in that the onebab spilled over around the exit of the steam vent passage and adhered to the top surface of the outer lid, spoiling the aesthetic appearance. In addition, in conventional rice cookers, the outer lid is generally pivoted to the rice cooker body, so it is not possible to wash the outer lid with water. Therefore, its removal became troublesome.

In addition, some known steam venting devices for rice cookers include a pot lid at the bottom of a steam pipe for discharging steam generated in the pot to the outside air, as shown in Japanese Utility Model Application Publication No. 51-74055. There is a known rice cooker in which a through hole opening toward the top is formed so that the steam separated from the steam in the steam pipe is discharged to the top surface of the pot lid through the through hole. In the steam venting device for a pot, the steam pipe is fixedly attached to the upper surface of the pot lid, so there is a problem in that it becomes difficult to clean the steam pipe that has adhered to the inside or around the steam pipe.

(Purpose of the invention) In view of the problems of the conventional steam venting device of a rice cooker as described above, the present invention separates oneva from steam containing a large amount of oneba passing through a steam vent passage.
The steam from which the oneva is removed or reduced is released into the outside air, thereby preventing or reducing the adhesion of the oneva to the top surface of the outer lid. It can be used both for positioning the steam pipe and for forming a steam passageway for guiding the steam pipe separated into the steam pipe below, and also to easily clean the steam pipe separated from the steam. This is the purpose.

(Structure of the invention) In a rice cooker that is provided with a steam pipe and a steam passage member that form a steam venting passage in the pot lid of a pot housed in the rice cooker main body, a plurality of vertical pieces are provided on the outer surface of the steam passage member. form a rib in the direction of
It is characterized in that the steam pipe is removably fitted into the rib-forming portion, so that a one-way passage is formed between each of the adjacent ribs.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS. 1 to 3. The rice cooker of this embodiment houses a pot 3 inside a rice cooker main body 1 having an insulated double wall structure. Furthermore, the top of the rice cooker body 1 is covered with a lid unit 2 consisting of an outer lid 4 having a heat insulating double wall structure and a pot lid 5 attached to the lower surface of the outer lid 4.
Reference numeral 6 denotes a rice cooking heater installed at the bottom of the rice cooker main body 1, and 7 a handle attached to the outer lid 4. The lid unit 2 is pivotally opened and closed by gripping the handle 7.

The pot lid 5 is removably suspended from a pin 19 provided at the center of the lower surface of the outer lid 4, so that the pot lid 5 can be removed from the lower surface of the outer lid 4 as needed. There is.

A steam venting device 10 is attached to the pot lid 5 so as to pass through the outer lid 4 and the pot lid 5 in the vertical direction.

The steam release device 10 includes a cylindrical steam passage member 12 made of synthetic resin forming a steam passage 31 that vertically penetrates the pot lid 5, and a steam passage made of aluminum or stainless steel that is placed over the top of the steam passage member 12. It is composed of a pipe 11.

The steam passage member 12 is formed into a stepped cylindrical body having an appropriate height and an upper cylindrical portion 12a having a smaller diameter than a lower cylindrical portion 12b. This steam passage member 12
is fixedly attached to the pot lid 5 by fitting an annular groove 32 formed in the lower cylindrical portion 12b into the edge of a hole 20 formed in a portion near the outer periphery of the pot lid 5.

A steam passage 31 formed in the steam passage member 12 is for communicating the inside of the pot 3 and the inside of the steam pipe 11, and the steam passage 31 is formed to have a considerably smaller diameter than the inner diameter of the steam pipe 11.

The steam pipe 11 is formed into a cylindrical inverted container shape that is open at the bottom. The ceiling 11a of this steam pipe 11 has small holes (4
) 23, 23... are formed.

Outlet opening 3 of steam passage 31 of steam passage member 12
1a is opened at a predetermined height higher than the lower end opening 22 of the steam pipe 11 in the space 21 within the steam pipe 11. The steam passage 31, the space 21 in the steam pipe 11, and the small hole 23 constitute a series of steam vent passages 13 for discharging the steam generated in the pot 3 to the outside air.

The steam generated in the pot 3 contains a large amount of oneba in the form of several drops, and the steam containing the oneba passes from the inlet opening 31b through the small diameter steam passage 31 to a relatively small portion of the steam pipe 11. Large diameter void 21
When the vapor is released into the air, it temporarily stays in the space 21 and becomes a turbulent flow, and at that time, the Oneva in the steam adheres to the inner surface of the steam pipe 11 and sequentially flows down the inner surface of the steam pipe 11. It becomes like this.
The steam flowing down the inner surface of the steam pipe 11 is controlled by the structure shown below.
The liquid is discharged onto the upper surface of the pot lid 5 from the lower end opening 22 (which serves as an opening for discharging the hot pot) 1.

On the outer surface of the portion of the steam passage member 12 that protrudes above the pot lid 5, there is a vertical L extending continuously from the upper cylindrical portion 12a to the lower cylindrical portion 12b.
A large number of shaped ribs 33, 33... are formed radially. L-shaped one-piece guide grooves 34, 34, . . . for guiding the one-piece lever downward are formed between the mutually adjacent ribs 33, 33, respectively. The outward protrusion width of each vertical rib part 33a, 33a... of the upper half portion of each rib 33, 33... is determined by the diameter of an imaginary circle connecting the outer surfaces of each vertical rib part 33a, 33a... The diameter is set to be approximately the same as the inner diameter of the The steam pipe 11 is detachably attached to the steam passage member 12 so as to cover the outside of the vertical rib portion 33a from above. Therefore, between the steam pipe 11 and the steam passage member 12,
A large number of Oneva passages 17 defined by the Oneva guide grooves 34, 34... and the inner surface of the steam pipe 11,
17... are now formed, and the oneva flowing down the inner surface of the steam pipe 11 passes through the oneva passage 17 and is discharged from the outlet onto the upper surface of the pot lid 5.

The outer periphery of the attachment part of the steam release device 10 in the pot lid 5 is recessed downward to form a oneva reservoir 15, and the oneva discharged from the outlet through the oneva passage 17 can be stored in the oneva reservoir 15. That's what I do.

The upper end of the steam pipe 11 is exposed to the outside air from the upper surface of the outer cover 4 through a vertical hole 14 formed in the outer cover 4.

To explain the operation of the steam release device 10 of this embodiment, steam generated in the pot 3 during rice cooking is released into the relatively large diameter space 21 in the steam pipe 11 through the small diameter steam passage 31. When this occurs, the steam temporarily remains in the space 21, and at that time, the Oneva contained in the steam is separated from the steam. The Oneva separated from the steam flows along the inner surface of the steam pipe 11, and further passes through the Oneva passage 17 and is sequentially passed through the pot lid 5.
It flows into the oneba reservoir 15 formed above and is stored there. On the other hand, the steam from which Oneba has been separated in the steam pipe 11 is released directly into the outside air through the small hole 23, but since the Oneva component is reduced in the steam released into the outside air, the Oneva component is reduced. Therefore, the upper surface of the outer lid 4 is hardly soiled.

Oneba W stored in oneba reservoir 15 of pot lid 5
When cleaning, the lid unit 2 is opened, the pot lid 5 is removed from the outer lid 4, and the steam pipe 11 is removed from the steam passage member 12 before being washed with water. In addition, if the steam pipe 11 is removed and cleaned, the steam pipe 11, the pot lid 5, and the steam passage member 12 can be thoroughly cleaned in every corner.

(Effects of the invention) The rice cooker steam release device of the invention has the following effects.

(1) In a rice cooker in which a steam pipe 11 and a steam passage member 12 are provided to form a steam vent passage 13 in the pot lid 5, the steam pipe 11 is removably fitted into the steam passage member 12. When cleaning the hotpot adhering to the pot lid 5, steam pipe 11, steam passage member 12, etc., the steam pipe 11 is removed from the steam passage member 12.
By removing it from the body, cleaning work is easy and every corner can be thoroughly cleaned.

(2) A plurality of vertical ribs 33, 33... are formed on the outer surface of the steam passage member 12, and the steam pipe 11 is fitted into the rib-forming portion, so that the ribs 33, 33, which are adjacent to each other, are spaced between each other. Since the oneba passage 17 is formed, the ribs 33, 33, which have a single structure, are formed in the steam passage member 12.
It can be used both for positioning the steam pipes 11 and for forming the oneba passage 17.
