Description

  This invention relates to the pressure type rice cooker which can control the pressure in a rice cooker with the pressure regulation valve provided in the lid | cover.

  This type of pressure rice cooker closes at least one pressure regulating valve built in the steam path between the inside and outside of the rice cooker, so that the pressure in the rice cooker is changed from atmospheric pressure during the rice cooking process. An elevated pressure state is generated (hereinafter, this state is referred to as a pressure rice cooking state), and the pressure can be controlled to a predetermined value by opening / closing control of the pressure regulating valve. In order to prevent the lid from being opened in the pressurized rice cooking state, a safety opening device is incorporated in the lid.

  Conventionally, the above safety release device includes a pressure regulating valve that fits in the pressure regulating valve installation chamber, a slider connected to the drive shaft of the solenoid coil, a guide that restricts the movement of the slider in the advancing / retreating direction of the drive shaft, and a hook releasing operation. What consists of the operation transmission part of the lid hook which transmits is used (patent document 1).

In the pressure rice cooker described in Patent Document 1, the slider has a frame shape, and the slider has both side frames that slide with the guide and both connections that connect both side frames on the same side in the advancing and retracting direction. It has a frame part and a lock part protruding to one side in a direction perpendicular to the advancing / retreating direction. The solenoid coil is disposed inside the frame hole. The slider is surely moved within a predetermined deflection width in terms of a function as a safety device by sliding of the both side frame portions and the guide. Here, since the rigidity of the both side frame portions affects the guide strength of the slider and the positioning strength of the lock portion, the slide is made frame-shaped by connecting the both connection frame portions, thereby increasing the rigidity.
The connection frame portion on the pressure regulating valve side of both the connection frame portions is provided with a valve operation shaft and is connected to a drive shaft. The lock part and the valve operation shaft are locked so that displacement of the operation transmission part to the hook release position is prevented even when the cover hook release button is pushed down by the advancement and retraction of the drive shaft, and the pressure regulating valve is allowed to close. It reciprocates between the position and the unlocking position where the displacement of the operation transmitting portion to the hook releasing position is allowed and the pressure regulating valve is forcibly opened. At the locked position, the lid hook is not disengaged, and the pressure rice cooking state can be performed, and the lid opening between them is reliably prevented. At the unlocked position, the lid can be opened, and rice cooking is possible. The lid can be reliably opened under the condition that the pressure in the pan is reduced.

Moreover, the pressure-type rice cooker described in patent document 1 arrange | positions a solenoid coil and a slider well by arrange | positioning a solenoid coil using between the both-sides frame parts of the slider made into the frame shape, In addition, it is easy to obtain the installation space for other parts.
Furthermore, by providing a lock portion protruding on one side in the direction orthogonal to the advancing / retreating direction of the slider, it is possible to arrange the other side frame portion as close as possible to the other end portion in the lid. The solenoid coil, pressure regulating valve, and slider can be placed as close as possible to the other end of the lid, and the space for installing other parts between the solenoid coil and the other end of the lid It is easy to obtain. Further, a non-linear arrangement of the operation transmitting portion of the lid hook provided corresponding to the hook release button of the lid, the solenoid coil, and the pressure regulating valve is enabled.

JP 2006-20962 A

  However, the pressure rice cooker described in Patent Document 1 is easy to arrange the safety opening device as close as possible to the other side of the lid as described above, but the reciprocating stroke of the connecting frame portion on the lid hook side is easy. In view of this, it is necessary to place the solenoid coil located in the slider hole away from the lid hook operation transmission part to the pressure regulating valve side. Since it moves away from the hook, there is room for improvement in terms of preventing the lid from being made compact.

  In view of the above circumstances, an object of the present invention is to arrange a safety opening device that prevents the lid from being opened in a pressurized rice cooking state closer to the lid hook side.

This invention which solves the above-mentioned subject is the pressure regulation valve built in the steam path between the inside of the rice cooker and the outside, the slider connected to the drive shaft of the solenoid coil, and the movement of this slider in the advance and retreat direction of the drive shaft A guide for regulating and an operation transmitting portion of a lid hook to which a hook releasing operation is transmitted. The slider has both side frame portions guided in the advancing / retreating direction by the guide, and the both side frame portions on the same side in the advancing / retreating direction. Both connecting frame portions to be connected and a lock portion provided on one side in a direction orthogonal to the advancing and retreating direction, and the solenoid coil is disposed between the both side frame portions, and the pressure regulating valve of the both connecting frame portions The connecting frame portion on the side is provided with a valve operation shaft and is connected to the drive shaft. The lock portion and the valve operation shaft are displaced to the hook release position of the operation transmission portion by the advancement and retraction of the drive shaft. Block and close the pressure regulator In the pressure rice cooker capable of reciprocating between a lock position allowing the operation and a lock release position for allowing the operation transmitting portion to move to a hook release position and forcibly opening the pressure regulating valve, The connection frame portion on the lid hook side passes through the space formed above or below the solenoid coil during the reciprocating movement, and the end portion on the lid hook side of the slider is in a state where the slider is in the lock position. The above configuration is characterized in that the solenoid coil is on the pressure regulating valve side with respect to the end portion on the lid hook side.
Here, the hook position refers to the position of the lid hook that is maintained in a state in which the lid hook is engaged with the shoulder portion of the body and the lid is closed. The hook release position refers to the position of the lid hook from which the engagement is released.

That is, if the connecting frame part on the lid hook side passes through the space formed above or below the solenoid coil during the reciprocating movement, the lid hook side of the slider including the both side frame parts and the lock part is provided. The end can be configured to be closer to the pressure regulating valve than the end on the lid hook side of the solenoid coil in a state where the slider is in the locked position. If this configuration is adopted, the slider does not have a portion that reciprocates on the lid hook side from the solenoid coil when reciprocating, and the slider can be disposed closer to the lid hook than that of the above-mentioned Patent Document 1.
Since the drive shaft of the solenoid coil is connected to the connection frame portion on the pressure regulating valve side, it does not protrude to the lid hook side. That is, if the relationship between the slider and the solenoid coil in the locked position is as described above, the solenoid coil can be disposed closer to the lid hook side.
Therefore, according to the present invention, the safety opening device can be arranged closer to the lid hook side based on the solenoid coil.

As a specific configuration in which the connecting frame portion on the lid hook side passes through the space formed above or below the solenoid coil, the configuration passing through the space above the solenoid coil, the configuration passing through the space below the solenoid coil, the solenoid The structure which passes through the space above and below the coil is mentioned.
Especially, the structure which the connection frame part by the side of a lid hook passes above a solenoid coil is preferable. Since the internal space of the lid above the solenoid coil can be used as the movement space, the structural change accompanying the formation of the movement space on the bottom surface in the lid can be avoided.

  As described above, the pressure rice cooker according to the present invention eliminates the need to secure a moving stroke from the solenoid coil to the lid hook side, and can arrange the safety release device closer to the lid hook side.

Hereinafter, the pressure type rice cooker concerning a 1st embodiment of this invention is explained based on an accompanying drawing.
FIG. 1 shows only the bottom surface in the lid of the pressure rice cooker according to the first embodiment from obliquely above. About another structure, since a well-known structure can be employ | adopted suitably as a pressure type rice cooker, illustration and description are abbreviate | omitted.
FIG. 2A shows a state where the safety release device is in the locked position from above. FIG. 2B shows the state where the safety release device is in the unlocked position from above.
FIG. 3 shows a cut surface taken along the line III-III in FIG.

  As shown in FIGS. 1 to 3, in the pressure rice cooker according to the first embodiment, an upper lid member 10 and a lower lid member 11 are coupled vertically to form an internal space of the lid. A reinforcing plate 12 is attached to the upper side of the lower lid member 11.

  The reinforcing plate 12 is formed of a single stainless steel plate and has a shape in which the vertical walls of the flanges 12a and 12a screwed to the rib structure portions formed on both sides in the width direction of the lower lid member 11 are connected by the flat plate portion 12b. It has become. Shaft support portions 12c and 12c through which the hook rotating shaft 13a of the lid hook 13 passes are formed at one end in the longitudinal direction of the vertical walls of the flanges 12a and 12a. Shaft support portions 12d and 12d through which the lid hinge shaft passes are formed at the other longitudinal ends of the vertical walls of the flanges 12a and 12a. A space that partially exposes the upper surface of the lower lid member 11 is formed in the flat plate portion 12 b of the reinforcing plate 12. From the space of the reinforcing plate 12, a pressure regulating valve installation chamber 21 into which the pressure regulating valve 20 is incorporated, a screw hole for assembling the safety release device, and the like protrude upward.

  When the hook portion 13b of the lid hook 13 comes to the hook release position where the lid is disengaged from the shoulder portion of the lid, the lid is naturally opened completely by the biasing force of the accumulated lid hinge spring. When the hook release button 14 of the lid is pushed down, the lid hook 13 moves to the hook release position by the transmission of the release operation in which the operation transmitting portion 13c protruding toward the pressure regulating valve 20 is pushed down by the hook release button 14. When the depression by the hook release button 14 is eliminated, the hook portion 13b naturally engages with the body shoulder portion by the spring biasing force accumulated around the hook rotation axis, and returns to the hook position where the lid is kept closed.

  In the first embodiment, in addition to the pressure regulating valve 20, another pressure regulating valve is provided. The normal rice cooking pressure is controlled by the other pressure regulating valve. The pressure regulating valve 20 functions as a safety valve that opens at a pressure higher than the maximum valve opening pressure of another pressure regulating valve. In the middle of the rice cooking process, both pressure regulating valves are closed, and the inside of the rice cooking pan is in a pressurized rice cooking state higher than atmospheric pressure. Another pressure regulating valve can be used for the safety opening device.

  The pressure regulating valve installation chamber 21 is provided in the lower lid member 11 and is a part of the steam path between the inside of the rice cooker and the outside. The pressure regulating valve 20 that fits in the pressure regulating valve installation chamber 21 is a ball valve that closes the valve hole 23 with the weight of the ball valve body 22. The ball valve body 22 is positioned so as not to be detached from the valve seat 24 by the valve seat 24 and the valve chamber member 25. When the pressure regulating valve 20 is opened, the steam generated in the rice cooking pan flows into the separation chamber through the steam path, and is eventually released to the atmosphere through the steam hole opened in the steam port cover. The pressure regulating valve 20 may be of any valve type as long as it can control the opening / closing operation of the valve body from the outside.

  The safety release device incorporated in the lid includes a pressure regulating valve 20, a slider 40 connected to the drive shaft 31 of the solenoid coil 30, and guides 51 and 52 that restrict the movement of the slider 40 in the advancing and retreating direction of the drive shaft 31. And the operation transmitting portion 13 c of the lid hook 13.

  As shown in FIGS. 1, 2 (a), (b), FIGS. 4 (a), (b), and (c), the slider 40 has a frame shape and is above the flat plate portion 12 b of the reinforcing plate 12. The side frames 41 and 42 guided in the advancing and retreating directions by the guides 51 and 52 protruding in the direction, the both connecting frame portions 43 and 44 connecting the both side frame portions 41 and 42 on the same side of the advancing and retreating directions, and the advancing and retreating directions orthogonal And a lock portion 45 provided on one side in the direction. The slider 40 is integrally injection molded. This is to prevent an increase in the number of parts.

  The side frame portion 41 is a frame portion in which a sliding surface with the guide 51 is formed in a series in the forward / backward direction on one side in a direction orthogonal to the forward / backward direction of the slider 40. The side frame portion 42 is a frame portion in which a sliding surface with the guide 52 is formed in a series in the forward / backward direction on the other side of the slider 40. The both side frame portions 41 and 42 are configured to slide on the horizontal plate surface of the flat plate portion 12b of the reinforcing plate 12 (with the lid closed).

  The solenoid coil 30 is disposed between the side frame portions 41 and 42.

  Both connection frame parts 43 and 44 are frame parts which connect the both side frame parts 41 and 42, respectively. The connection frame 43 on the pressure regulating valve 20 side is integrally provided with a valve operating shaft 43 a and is connected to the drive shaft 31. The valve operation shaft 43 a abuts against an elastic seal member 21 a constituting a part of the chamber wall of the pressure regulating valve installation chamber 21. As shown in FIG. 3, the ball valve element 22 that closes the valve hole 23 and the valve operating shaft 43a face each other in the axial direction with the elastic seal member 21a interposed therebetween. The drive shaft 31 may be the valve operation shaft 43a.

  As shown in FIGS. 2A, 2 </ b> B, and 3, the drive shaft 31 is drawn into the solenoid coil 30 by excitation of the solenoid coil 30, but does not protrude from the solenoid coil 30 toward the lid hook 13. . The coil spring 32 incorporated between the solenoid coil 30 and the connection frame 43 on the pressure regulating valve 20 side is compressed as the drive shaft 31 is retracted. When the solenoid is no longer excited, the drive shaft 31 protrudes toward the pressure regulating valve 20 by the spring force accumulated in the coil spring 32. Thereby, as a result of the drive shaft 31 being advanced and retracted by the control of the solenoid coil 30, the slider 40 reciprocates.

  Since the drive shaft 31 and the valve operation shaft 43a bring the pressure regulating valve 20 as a whole toward the center of the lid, as shown in FIGS. 4B and 4C, the valve operation shaft 43a is moved forward and backward. An eccentric amount δ is given to one end side in the direction orthogonal to each other. This is to enhance the performance of the heat retaining function applied to the pressure rice cooker. That is, as shown in FIGS. 3 and 5, the valve hole 23 of the pressure regulating valve 20 communicates with a hole 15 a vacated in the heater cover 15 attached to the lower side of the lower lid member 11. On the upper side of the heater cover 15, a lead wire 15b serving as an electric heater is attached along the outer periphery. As the lead wire 15b is closer to the outer periphery, the lead wire 15b can be disposed longer in the heater cover 15, and as a result, the heat generation efficiency can be improved and the heat retaining performance can be improved. For this reason, the pressure regulating valve 20 as a whole is moved closer to the lid center side so that the hole 15a is moved closer to the center side from the outer periphery of the heater cover 15. If there is no such purpose, the drive shaft 31 and the valve operation shaft 43a shown in FIGS. 2A and 2B may be connected concentrically.

  As shown in FIGS. 1, 2 (a), and (b), the connection frame portion 44 on the lid hook 13 side is provided in a bridge shape over the solenoid coil 30.

  The lock part 45 protrudes from the side frame part 41 on one side to the same side. In the first embodiment, when the lock portion is provided on one side in the direction orthogonal to the advancing / retreating direction of the slider 40, the lock portion protrudes from the side frame portion 41 to the same side, but the lock portion is connected to the connection frame portion 44 on the lid hook 13 side. 45 can also be provided. In this embodiment, the safety opening device is arranged on the left side in the drawing as viewed from above, and one side in the direction orthogonal to the forward / backward direction is the right side in the drawing. Is possible.

  As shown in FIGS. 2A, 2 </ b> B, 6 </ b> A, and 6 </ b> B, the operation transmission portion 13 c protrudes above the flat plate portion 12 b of the reinforcing plate 12. The lock part 45 is linearly arranged with the operation transmission part 13c by providing it so that it may protrude in one side rather than the sliding surface of the side frame part 41 of one side.

As the drive shaft 31 advances and retreats, the lock portion 45 and the valve operation shaft 43a are displaced from the lock portion 45 to the hook release position on the rotation radius of the operation transmission portion 13c, as shown in FIGS. And a lock position where the valve operating shaft 43a does not push the ball valve body 22 and allows the pressure regulating valve 20 to close, and as shown in FIGS. 2 (b) and 6 (b), the lock portion 45 Is disengaged from the rotational radius of the operation transmitting portion 13c toward the pressure regulating valve 20 side to allow the operation transmitting portion 13c to be displaced to the hook release position, and the valve operating shaft 43a causes the ball valve body 22 to pass through the elastic seal member 21a. It is pushed and floated from the valve hole 23, and can be reciprocated with the unlocking position where the pressure regulating valve 20 is forcibly opened.
Therefore, in the locked position shown in FIG. 2A and FIG. 3, the lid hook 13 is not disengaged, and the pressurized rice cooking state can be performed, and the lid opening during that can be reliably prevented. In the unlock position shown in FIG. 2 (b) and FIG. 6 (b), the lid can be opened and the lid can be reliably opened under the condition where the pressure in the rice cooker is reduced. . The reason why the solenoid coil 30 is moved to the lock position by exciting the solenoid coil 30 is that even if the solenoid coil 30 breaks down, the movement to the lock release position can be secured by the coil spring 32. This is because it is superior in safety.

  As is apparent from FIGS. 2A and 2B, the connecting frame portion 44 on the lid hook 13 side passes through the lid internal space formed above the solenoid coil 30 during the reciprocal movement, and the slider 40 It is above the solenoid coil 30 in the locked position. Further, in the state where the slider 40 is in the locked position, the end of the slider 40 on the lid hook 13 side is closer to the pressure regulating valve 20 than the end of the solenoid coil 30 on the lid hook 13 side. The end portion on the lid hook 13 side of the slider 40 is a portion forming the end on the lid hook 13 side in the forward / backward direction of the slider 40. In the first embodiment, the connection frame portion 44, the both side frame portions 41, 42 on the side of the lid hook 13, on the side of the lid 45 on the side of the lid hook 13, and on the side of the lid hook 13 of the rotation restricting portion 46 protruding from the lock portion 45 and the connecting frame 44 toward the side of the lid hook 13. It is formed with an end.

  As shown in FIGS. 4, 6A, and 6B, the rotation restricting portion 46 of the slider 40 is located on the rotation radius of the operation transmitting portion 13c, is lower than the lock portion 45, and is on the lid hook 13 side. Is provided. As shown in FIG. 6B, in a state where the slider 40 is in the unlocking position, the height difference between the rotation restricting portion 46 and the locking portion 45 enables the displacement of the operation transmitting portion 13c to the hook releasing position. The rotation restricting portion 46 and the operation transmitting portion 13c come into contact after the operation transmitting portion 13c reaches the hook release position. Thus, the rotation restricting portion 46 prevents the operation transmitting portion 13c from being pushed down unnecessarily after the hook is released. Further, since the rotation restricting portion 46 is higher than the horizontal plate surface of the flat plate portion 12b, even if the attachment position of the flat plate portion 12b with respect to the upper cover member 10 is lowered, the rotation restriction of the lid hook 13 can be performed. it can. As a result, the internal space of the lid can be expanded while maintaining the height from the flat plate portion 12b of the vertical wall of the flanges 12a and 12a of the reinforcing plate 12, and thus the lid can be made compact in the vertical direction.

  As shown in FIGS. 2A and 3, the pressure rice cooker according to the first embodiment having the above configuration is configured such that the end of the slider 40 in the lock position on the lid hook 13 side is the lid of the solenoid coil 30. Since the drive shaft 31 does not protrude from the solenoid coil 30 to the lid hook 13 side than the end on the hook 13 side, the solenoid coil 30 can be disposed closer to the lid hook 13 side. As a result, the lock part 45 is provided in the one side frame part 41, and the solenoid coil 30 and the operation transmission part 13c of the lid hook 13 are non-linearly arranged so that the operation transmission part 13c is shifted to one side when viewed from above. As is apparent from the drawing, the solenoid coil 30 can be brought closer to the lid hook 13 side until it is positioned beside the operation transmitting portion 13c of the lid hook 13. Accordingly, the arrangement space for the parts and the structure part can be obtained on the pressure regulating valve 20 side, so that it is possible to reduce the size in the lid length direction.

  In the first embodiment, the connection frame portion 44 on the lid hook 13 side passes above the solenoid coil 30. However, as shown in the second embodiment in FIGS. A space 82 of the lower lid member 11 may be formed below, and the connection frame portion 81 may pass through the space 82. The space 82 is opened up and down in a region on the heater cover 15 of the lower lid member 11, and after passing the connecting frame portion 81 through the solenoid coil 30 and the space 82, the heater cover 15 is moved to the lower lid member. Before being attached to 11, it is sealed with a seal member 83.

In the first embodiment, the lock portion 45 is directly engaged with the operation transmission portion 13c of the lid hook 13 so that the lock portion 45 prevents the operation transmission portion 13c from being displaced to the hook release position. Of course, it is possible to adopt a configuration in which the lock portion 45 indirectly prevents the displacement of the operation transmission portion 13c.
For example, a configuration in which the lock portion 45 is engaged with the lower end of the hook release button 14 and a configuration in which a transmission link is provided between the hook release button 14 and the operation transmission portion 13c and the lock portion 45 is engaged with the transmission link are employed. It is also possible.

  Hereinafter, as an example, a third embodiment of the present invention will be described with reference to FIG. As shown in the figure, in the third embodiment, the lower end of the hook release button 14 ′ is engaged with the transmission leg 14a for transmitting the release operation to the operation transmission portion 13c ′ of the lid hook 13 and the lock portion 45 ′. A locking leg 14b is formed. With the slider 40 ′ in the locked position, the lock portion 45 ′ is positioned on the radius of rotation of the locking leg portion 14b of the hook release button 14 ′, so that the depression of the hook release button 14 ′ is prevented from being locked. As a result, the transmission leg portion 14a cannot push down the operation transmission portion 13c ′ of the lid hook 13, and the displacement of the operation transmission portion 13c ′ to the hook release position is prevented. With the slider 40 'in the unlocked position, the lid hook 13 is restricted from being rotated at the hook release button 14' and the rotation restricting portion 46 'due to the height difference between the rotation restricting portion 46' and the lock portion 45 '.
