Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a rice cooker, such as a drop-in stove with a rice cooker, in which the rice pot can be put in and taken out by sliding it back and forth.

[Conventional technology]

As shown in FIG. 8 of the accompanying drawings, for example, in the conventional technique, the support part 5' of the rice cooker A' is placed on a straight receiving rail 2' fixed and fixed inside the rice cooking chamber. One has a structure in which the rice cooker A' is guided and supported by a rail 2', and the other has a structure disclosed in Japanese Utility Model Application No. 97522 of 1988.

[The problem that the idea aims to solve]

In the conventional technique described above, when the rice cooker A' is slid in and out, the rice cooker A' slides linearly and substantially horizontally along the receiving rail 2'. Then, when inserting and setting the rice cooker A', the relationship between the heat sensitive element 6' that thermally senses the completion of rice cooking and the rice cooker A' is set.
It is necessary to press down the heat sensitive element 6' slightly at the bottom of the rice cooker A' and press it tightly against the bottom of the rice cooker A' while maintaining elasticity. It is slightly higher than the bottom of pot A′.
Therefore, when rice cooker A' is inserted into the rice cooking chamber, the lower part of the rear end of rice cooker A' hits the upper side of the heat sensitive element 6', and as it climbs over the heat sensitive element 6', the heat sensitive element 6' is pushed down and tilted greatly. A very large frictional force is generated, and the heat sensitive element 6' may be destroyed (see the state shown by the solid line in Figure 8), and the rice cooker may be damaged.
Even if the bottom surface of A' and the top surface of the heat sensitive element 6' are chamfered sufficiently large and the bottom of the pot presses down the heat sensitive element 6 normally, rice cooker A' presses down on the heat sensitive body 6'. An elastic direct reaction force is in effect from the time of contact, and a frictional force is generated while the rice cooker pot A' moves horizontally to the rear. 6' and 6' move strongly against each other under a considerably large frictional force, so the abrasions that occur on the bottom of the pot and the heat sensitive element 6' are significant. It is difficult to insert, set and pull out A', and since it is frequently used, there is a strong demand for improvement.

In addition, in the device proposed in Utility Model Publication No. 97522 of 1988, there is a structure in which the rice cooker must be tilted when placing the rice cooker in an accurate setting position and when taking it in and out, and furthermore, There was a problem as to whether it was possible to always accurately sense the temperature at the bottom of the pot by pressing down on the heat-sensitive member at the bottom.

Therefore, this idea was developed by lowering the rice cooker at a predetermined position, for example, into the landing state represented by an airplane, so that frictional force between the bottom of the rice cooker and the heat-sensitive element is generated at a short distance just before the end of the rice cooker's movement. To provide a slide-type rice cooker in which the setting position of the rice cooker can be easily determined, and a heat-sensitive member is pushed down a predetermined distance at the bottom of the rice-cooker, and the bottom of the rice cooker and the top surface of the heat-sensitive member are pressed into close contact with each other. It is something to do.

[Means to solve the problem]

This invention is based on a rice cooker in which the rice cooker A is slid back and forth into and out of the rice cooking chamber 1, and a receiving rail 2 that is fixed to the rice cooking chamber 1 and guides and supports the rice cooker A is placed at a predetermined position in the rice cooking chamber 1. Engagement recesses 3 are provided at predetermined intervals at two locations, front and rear, to set the horizontal position and height at which the heat sensitive element 6 is securely pressed into contact with the center of the bottom of the rice cooker A to be inserted into the rice cooker A. In addition, the supporting part 5 of the rice cooker A is provided with two engagement protrusions 4 on the front and back that engage and disengage with the engagement recess 3 of the receiving rail 2, and the rice cooker A can be slid in and out of the engagement recess. 3, the setting position and height at the time of inserting and setting the rice cooker A are set when the engaging protrusion 4 engages and disengages, thereby solving the above-mentioned problems.

[Effect]

Since this invention adopts the above-mentioned technical means, the support part 5 of the rice cooker A is provided on the support part 5 on the receiving rail 2 which is fixed and fixed inside the rice cooking chamber 1.
The rice cooker A is supported on the receiving rail 2 with the engaging convex portions 4 placed thereon, and the rice cooker A is slid backward along the receiving rail 2 until the rice cooker A reaches the set position in the rice cooking chamber 1. The two engagement convex portions 4 at the front and rear of the support portion 5 are fitted into and engaged with the two engagement concave portions 3 of the receiving rail 2, and the rice cooker A is positioned approximately directly below the engagement concave portions 3 by the depth (height) thereof. , and press down the heat sensitive element 6 at the center of the pot bottom to bring the heat sensitive body 6 into close contact with the center of the pot bottom while maintaining elasticity, and the receiving rail 2
The engagement convex portion 4 of the support portion 5 fits into the engagement recess 3 of the rice cooker A to prevent movement of the rice cooker A, thereby reliably determining the setting position of the rice cooker A with respect to the rice cooking chamber 1.

When rice cooking pot A is to be taken out from rice cooking chamber 1 when rice cooking is complete or for other reasons, by pulling rice cooker A forward, the engagement convex portion 4 of its support portion 5 will escape from the engagement concave portion 3 of receiving rail 2, and from then on. The rice cooker A slides forward along the receiving rail 2.

〔Example〕

Examples of this invention will be described below based on the drawings. The illustrated embodiment is an example applied to a drop-in stove rice cooker equipped with a rice cooker and a grill that are incorporated into a kitchen unit. Room, A
is a rice cooker, and the rice cooking door 7 on the front side of the rice cooking chamber 1 is
You open it and slide it back and forth to put it in and take it out. Reference numeral 2 denotes a receiving rail installed and fixed at a predetermined position in the rice cooking chamber 1, and is used to support the support portion 5 of the rice cooker A and guide and support the rice cooker A. For example, as shown in detail in FIG. The receiving rails 2, which are arranged in parallel on both sides, are integrally connected at the rear ends by connecting rods 8 to increase their strength and to be able to sufficiently withstand the weight of the rice cooker A. A support leg 9 extending from the side is formed into a loop shape so that the support leg 9 can be vertically attached to and detached from a rail receiver 11 fixed to the inner wall 10 of the rice cooking chamber 1. Reference numeral 3 denotes engagement recesses provided in the receiving rail 2 downward and spaced apart from each other in the horizontal direction where the bottom of the rice cooker A set in the rice cooking chamber 1 and the heat sensitive element 16 come into pressure contact. This is for setting the position and height (vertical position) of the
In the illustrated embodiment (hereinafter referred to as the first embodiment), a diagonal portion that is gently inclined toward the entrance/exit side of the engagement convex portion 3 is used.
3a, so that the engagement protrusion 4 on the side of the rice cooker A, which will be described later, can be easily engaged and disengaged. There is no problem in practice even if the concave portion is simply an arcuate concave portion without a gently sloped portion.

The depth (height) of the engaging recess 3 is the same as that of the rice cooker A.
The amount of descent of the rice cooker A is regulated to a constant level, and the heat-sensitive element 6 (described below) is slightly pushed down at the bottom of the rice cooker A, so that the heat-sensitive element 6 and the bottom of the pot can be brought into close contact with each other most effectively while maintaining a certain elasticity. Dimensions. 4 is an engaging protrusion provided on the lower surface of the support part 5 of the rice cooker A at a distance from each other in the front and back;
The engaging protrusion 4 is adapted to engage and disengage from the engaging recess 3 of the receiving rail 2 by sliding the rice cooker A in and out along the receiving rail 2. In addition,
The lower end of this engaging protrusion 4 is made into an arcuate surface as in the embodiment, so that the contact area with the rail 2 for receiving the pressing force of the rice cooker A is increased, and the surface pressure generated by the pressing force of the rice cooker A is reduced. Glides easily. 6 is a heat-sensitive element that detects the completion of rice cooking based on the temperature at the bottom of the pot.

In the figure, 7 is the rice cooking door installed in the front of the rice cooking chamber 1;
12 is a gas burner that heats the rice cooker A, 13 is a push-button operation button for the rice cooker, and 14 is a slide lever-type adjustment knob that also sets the reserved rice cooking time. Also, G is a grill installed in parallel with the above rice cooker. 15 is a grill door, 16 is a push-button operation button thereof, 17 is a push-button operation button for stove C, and 18 is an exhaust port.

In the above configuration, when cooking rice, when opening the rice cooking door 7 and inserting and setting the rice cooking pot A into the rice cooking chamber 1, the rear part of the support section 5 of the rice cooking pot A is fitted on the receiving rail 2 in the rice cooking chamber 1. Convex portion 4 receiving rail 2
Place the rice cooker A in a position beyond the engagement recess 3 at the front of the rice cooker (see Fig. 4), push the rice cooker A backwards along the receiving rail 2, and slide it.The rice cooker A reaches the set position in the rice cooking chamber 1. Then, the two engagement protrusions 4 on the rice cooker A side are fitted into and engaged with the two engagement recesses 3 of the receiving rail 2, respectively. At this time, in the first embodiment, the engaging protrusion 4 is guided by the oblique part 3a on the entrance/exit side of the engaging recess 3 and fits into the engaging recess 3, and the rice cooker A gradually descends while maintaining a substantially horizontal position. Therefore, the setting can be done smoothly without any shock.
Also, its escape is similarly smooth and easy.
In the second embodiment, the distance from when the engaging protrusion 4 fits into the engaging recess 3 and the engagement is completed is a little shorter than that described above, and the descending speed of the rice cooker A is a little steeper. Shocks caused by descent will not be a problem in implementation. Moreover, only a rather large tensile force is required for escape.

The engaging protrusion 4 of the rice cooker A is fitted into the engaging recess 3 of the receiving rail 2, and the rice cooker A is inserted into the engaging recess 3.
, the heat sensitive element 6 is pushed down slightly at a position slightly in front of the center of the hook bottom to ensure that the heat sensitive element 6 is brought into close contact with the center of the hook bottom, and the engagement recess of the receiving rail 2 is lowered. The engaging convex portion 4 of the support portion 5 fits into the rice cooker 3 to restrict the movement of the rice cooker A to the set position, so that the set position of the rice cooker A with respect to the rice cooking chamber 1 is always fixed at a constant position.

Then, just before the set position of the rice cooker A, the rice cooker A comes into contact with the heat sensitive element 6, and a frictional force is generated due to the direct reaction force, which increases until it reaches the set position, but the maximum frictional force is This is the frictional force generated by a predetermined pressing force of the two, and it can be considerably reduced by making the contact surface between the two smooth.

[Effect of idea]

As explained above, this invention reduces the distance in which the horizontal contact friction force acts between the entire upper surface of the heat sensitive element and the bottom of the rice cooker when inserting and removing the rice cooker, and Unlike conventional methods, when the bottom of the rice cooker and the heat-sensitive element touch each other and the rice-cooking pot passes over the heat-sensitive element, the large pushing force generated on the heat-sensitive element and the associated large frictional force do not cause significant scratches. The insertion set has a simple structure so that the setting position in the horizontal direction and the vertical direction can always be set at a constant position, and the operation can be performed easily. Furthermore, since the rice cooker's support part is provided with two engagement protrusions on the front and back, when the rice cooker is placed on the receiving rail, the rice cooker slides horizontally without tilting, and the engagement The mating protrusion and the two engaging recesses provided on the receiving rail allow the rice cooker to maintain its horizontal position and descend almost directly below, so the bottom of the rice cooker presses down slightly on the top surface of the heat sensitive element, allowing it to come in close contact with the rice cooker. do. Therefore, the temperature at the bottom of the pot can always be sensed stably and accurately. Furthermore, there is no need to chamfer the upper circumferential edge of the heat sensitive body, and the heat transfer area can be increased, which has the effect of increasing thermal contact.

In addition, if the oblique part 3a is provided on the entrance/exit side of the engagement recess 3 as in the first embodiment, the engagement protrusion 4 on the rice cooker A side can be easily engaged and disengaged, and moreover, the setting and removal of the rice cooker A is easy. can be performed smoothly and eliminate impact loads.
