The present invention relates to a control device which is installed to expose the operation handle on the upper surface of the casing and the upper surface of the operation plate, for example, relates to a control device suitable for cooking utensils and the like, such as juices boiling in a cooking pot flows into the operation handle portion. .

In a mechanism operating device of the type in which the operation handle is exposed on the upper surface of the upper plate of the cooking utensil, a countermeasure against spilling of soup or the like is necessary. For this reason, in the mechanism operating device of Japanese Utility Model Publication No. 57-116048, an annular convex portion protruding upward is formed at the peripheral edge of the through hole for inserting the operation shaft portion of the upper plate portion, and the diameter is larger than the annular convex portion. An operation knob provided with a disc portion is formed integrally with the operation shaft portion passing through the through hole. Therefore, in the case where the mechanism operating device is used for a hot air balloon, the soup and the like that flowed down to the top plate are blocked by the annular convex portion, and the gap between the outer circumference of the operating shaft is blocked by the disc portion of the operation handle. The problem of inflow into the mechanism through the gap of the outer circumference of the operating shaft is avoided.

On the other hand, as disclosed in Japanese Utility Model Publication No. 59-4904, a decorative ring can be provided on the same axis with respect to an operation handle, and the operation handle can be rotated into a recess formed in the decoration ring. There is a form of acceptance. In this prior art, since the operation shaft portion and the axis of the operation handle attached to the horizontal axis are set horizontally, the liquid, which penetrates through the front of the instrument, even if the operation handle is accommodated in the recess, the gas cock, etc. Does not reach the installation of the calorie control device.

In the former mechanism operating device, the annular convex portion is provided at the edge of the through-hole for inserting the operation shaft portion of the upper plate portion, and the height is formed to solve the problem of soaking of the soup or the like. However, in order to protrude this annular convex part to the upper side operation handle side, there exists a processing limitation, and this is very difficult especially when an upper plate part is a glass upper plate. In addition, when the latter mechanism operating device is employed as it is in the upper plate of a mechanism such as a drop-in furnace, and the operation knob is arranged in an upward position on the upper surface of the upper plate, it is stored in the recess. The juice and the like reach over the annular convex portion and reach a calorific control device such as a gas cock or a calorie switch disposed on the lower side and damage it.

The present invention has been made to solve the above problems, and a first object of the present invention is to solve the problem that the juice or the like introduced from the operation handle side reaches the control means connected to it through the shaft member at the operation handle. To provide a control device. The second object of the present invention is to provide an inexpensive operation device by simplifying the device and improving the assembling work by the device in addition to the first object.

Solution to Problem The invention according to claim 1, which has been made to solve the above problem, corresponds to the first object, which is defined as "a shaft member penetrating the shaft hole of an operation plate and an outer side of the operation plate. An operation knob attached to one end and a control means connected to the other end of the shaft member at an inner side of the operation plate to switch or adjust a predetermined function by operating the operation knob, the operation plate and the control means; And a cover member which is externally fitted to the shaft member and substantially covers the outer fitting portion and protrudes radially outwardly.

In this case, the cover member is formed between the operation handle and the control means even if the juice or the like flows in through the shaft hole of the operation plate and flows toward the control means. It stops reaching this control means. That is, since the cover member is substantially occluded in the outer fitting portion fitted to the shaft member, the liquid and the like which flowed down through the shaft member from the shaft hole are prevented from flowing to the control means side by the occlusion. In addition, since the cover member is formed to protrude radially outward, the liquid or the like which has flowed down to the cover member acts to flow down the control means due to the presence of the protruding portion of the cover member. Accordingly, in response to the first object, the problem that the juice or the like introduced from the operation handle side flows directly to the control means or the juice or the like reaches the control means is eliminated. Since the cover member is attached to the intermediate portion of the shaft member by only fitting it to the outside, it is possible to simplify the apparatus and facilitate the assembly work in response to the second purpose.

In addition, the term "liquid juice" as used herein includes liquids overflowing on the operation plate for any reason, in addition to the literal juice that the soup boils over in the member to be cooked. It may be included. In addition, in this solving means, the posture state of the shaft member may be in an inclined posture state in addition to the vertical direction. The cover member may be formed to protrude only in a predetermined radial direction in addition to being protruded over the entire circumference of the shaft member.

The solution of the invention according to claim 2 limits the shape of the cover member according to claim 1, wherein the cover member has a protruding shape larger than the projection shape viewed from the vertical direction. do. According to this solution, even if the control means is attached to the downstream side of the juice or the like, i.e., the downstream side where the juice or the like which flows in from the operation handle side flows down, the cover member has a protruding shape that can cover the control means. Therefore, the liquid or the like is prevented from directly flowing to the control means or reaching the control means by the cover member. In addition, since the cover member has a protruding shape larger than the projection shape of the control means viewed in the vertical direction, the operation handle, the shaft member, and the control means are moved in the vertical direction in addition to the operation device in which the operation handle, the shaft member, and the control means are arranged in the vertical direction. Also for the operation device arranged at an angle to the liquid, the juice and the like are prevented from reaching the control means. In addition to protruding the cover member over the entire circumference of the shaft member, the cover member may be protruded only in a predetermined radial direction. In addition, when a plurality of cover members are used, the size of the synthesized cover member that is configured to be fitted outside to the shaft member is substantially large even if the protrusion shape of each cover member is smaller than the control means (for example, And the control means may be larger than the projection shape seen from the vertical direction. As described above, in the above solution, the problem that the juice reaches the control means is solved and the apparatus is simplified, thereby improving workability.

The solution of the invention according to claim 3 limits the attachment of the cover member according to claim 1 or 2, which means that " an elastic locking member that contracts radially inwardly is fitted to the shaft member and By pressing the cover member in the axial direction and fixed to the shaft member. According to this solution, the cover member is fixed to the shaft member by using an elastic locking member fitted to the shaft member. In this case, the shaft of the elastic locking member is utilized by using the contraction inward in the radial direction of the elastic locking member itself. Both ease of attachment work to the member and closure of the outer fitting can be obtained. The cover member is simply attached to the cover member by being pushed in the axial direction and fixed by the elastic locking member, and thus the device can be easily assembled without increasing the volume. Therefore, in this solution, the assembly workability which is the second object is improved in addition to the first object.

The solution of the invention according to claim 4 has defined the cover member according to claim 1 or 2, wherein at least the periphery of the periphery of the cover member fitted to the shaft member is an elastic member that contracts radially inward. Formed ”. According to this solution, since the periphery of the through-hole of the cover member is formed of an elastic member that contracts radially inward, when the outer diameter of the shaft member abutting the fitting portion is set equal to or smaller than the inner diameter of the through-hole, The cover member can be easily externally fitted to the shaft member, and the clogging property of the outer fitting portion is increased. Thus, the first and second objects described above are achieved.

The solution of the invention as defined in claim 5 limits the cover member according to claim 1 or 2, wherein the cover member is fixed to the shaft member by being pressed in the axial direction by a part of the operation knob. It is characterized by. According to this solution, the cover member can be easily fixed by pressing a part of the operation knob in the axial direction while the cover member is externally fitted to the shaft member. That is, since the cover member is pressed and fixed using the operation handle, it can be attached easily without requiring an attachment member. Accordingly, in response to the first and second objects, the problem of the liquid reaching the control means is solved, and the apparatus is simplified and the workability is improved.

The solution of the invention as defined in claim 6 limits the cover member according to any one of claims 1 to 5, wherein the cover member is provided with a defect portion penetrating the front and back surfaces of the cover. . According to this solution, if the liquid or the like falls on the cover member, the liquid or the like on the surface of the cover member is discharged through the defect due to its weight. Therefore, if a defect is formed in the cover member so that the juice is discharged to a specific part inside the apparatus in advance, the juice from the cover member is guided to the defect and discharged from the defect, thus eliminating the problem that the juice reaches the control means. .

The solution of the invention according to claim 7 includes: "A shaft member penetrating the shaft hole of the operation plate, an operation handle attached to one end of the shaft member at an outer side of the operation plate, and an inner side of the operation plate. Control means connected to the other end of the shaft member to switch or adjust a predetermined function by operating the operation knob, and fixed to the edge of the shaft hole and to the outside of the operation plate along the circumferential edge of the shaft hole. And a cover member forming a protruding wall shape.

According to this solution, the cover member has a wall shape protruding to the outside of the operation plate along the circumferential edge of the shaft hole. Therefore, the cover member becomes a partition member for partitioning the shaft hole of the operation plate, and the open hole position of the shaft hole is substantially higher than the surface of the operation plate. Therefore, even if the liquid or the like tries to penetrate through the shaft hole from the outside of the operation plate, it is difficult to pass over the cover member, so that intrusion into the shaft hole is prevented. In this way, the problem of the liquid reaching the control means inside the operation plate through the shaft hole in response to the first object is solved.

The solution of the invention according to claim 8 limits the cover member in claim 7, wherein the cover member is fixed by fitting the edge of the shaft hole in the axial direction. According to this solution, the cover member is fixed to the operation plate by fitting the edge portion to the cover member using the shaft hole. As a result, the edge portion of the shaft hole is fixed by the cover member, and a protruding wall is formed at the edge portion, whereby intrusion of juice or the like is prevented. On the other hand, a separate attachment member is not necessary for attaching the cover member, and the cover member can be easily attached by, for example, bending the cover member. Accordingly, in response to the first and second purposes, while the intrusion of juice or the like into the operation plate is prevented, the apparatus is simplified and the assembly workability is also improved.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described in detail based on drawing.

In the present embodiment, as shown in FIG. 1, the present invention is implemented in the operation unit of the drop-in furnace, and the main body case 73 opened upward in the open hole 71 formed in the countertop 70 is fitted. The support flange 74 of the upper end of the main body case 73 is supported by the circumferential edge of the open hole 71 and covers the opening of the main body case 73 with the upper plate 63. An operation plate 60 having a constant width is formed at the front edge portion of the upper plate 63, and an operation device for operating the calorie control device 30 is provided on the operation plate 60.

The circumferential edge of the support flange 74 and the upper plate 63 protruding from the circumferential edge of the main body case 73 is supported by the open hole circumferential edge of the countertop 70 through the packing 72. In the main body case 73, a bracket 31 for attaching the calorific control device 30 is formed in parallel with the operation plate 60 formed at the front edge of the upper plate 63, and both ends of the main body case 73 are formed. The bracket 31 is attached to the front edge of the main body case 73 opening part in a bridge shape by being fixed to the side wall of the head).

The operation plate 60 is formed inclined with respect to the operation side as shown in the cross section in FIG. On the operation plate 60, an annular wall 61 formed so as to protrude upward by extrusion is formed at a portion where the operation handle 20 is located. The calorie control device 30 is fixed to the upper surface of the bracket 31, the operation shaft 10 is fixed to the calorie control device 30 is connected. The operation shaft 10 is fitted in a non-contact state to the opening hole 62 of the operation plate 60 so as to be substantially perpendicular to the operation plate 60, and an operation handle is attached to the operation plate 60 side. . As the calorie control device 30, for example, a gas cock for gas volume control is employed in the case of a gas stove, and a calorie switch for controlling the amount of electricity supplied to the heater in the case of an electric stove.

The operation knob 20 is integrally formed with a disc portion 26 having a maximum outer diameter, an operation knob 27, and a shaft portion 23 to which the operation shaft is fitted and fixed. The operation handle 20 and the operation shaft 10 are fixed in the axial direction by screwing or press-fitting or the like.

The cap 40 as a cover member is fixed to the inside of the operation plate 60 of the operation shaft 10. The cap 40 is a main body case 73 through a hole 62 in which a juice or liquid (for example, water overflowed for some reason on the operation plate 60), such as a soup boiled from a cooking pot, or the like. ) Is installed in order to avoid the problem of invading into the calorie control device (30).

The cap 40 has a thin disc shape, and has a through hole 46 formed on the same axis as the operation shaft 10. The outer periphery of the operating shaft 10 is fitted into the through hole 46 so that the cap 40 is fitted outside the operating shaft 10. As a result, the cap 40 protrudes radially outward from the operation shaft. According to this embodiment, since the inner diameter of the through hole 46 is set slightly larger than the outer diameter of the operation shaft 10, the fixing of the cap 40 and the operation shaft 10 is, for example, an elastic locking member. It is fixed by the O-rings 50 and 51. Moreover, it does not interfere with installing the rotation stopper of the cap 40 on the operation shaft 10. FIG.

The fixed state of the cap 40 with respect to the operation shaft 10 is according to the present embodiment, and as shown in FIG. 2, the pair of O-rings 50 and 51 are externally fitted to the operation shaft 10 to thereby provide a cap. 40 is held and fixed by the clamping force acting in the axial direction of these O-rings 50 and 51. Since the O-rings 50 and 51 act to contract inward in the radial direction, when the outer rings are fitted to the operation shaft 10, the outer rings are blocked. That is, the axis line (up-down) direction of an operation shaft is closed. Then, the cap 40 is clamped by the O-rings 50 and 51 so that a reaction force that contracts in the axial direction acts so that the cap 40 is fixed to the operation shaft 10. In this embodiment, since the annular groove 11 is formed on the same axis as the axis in the operation shaft 10, the annular groove 11 defines the attachment position of the O-rings 50, 51. The position in the axial direction is determined, and this annular groove 11 determines the attachment position in the height direction of the cap 40. In addition, the O-rings 50 and 51 are easily attached by the annular groove 11.

Therefore, in such a configuration, when the juice by the juice flows down to the operation plate 60 side and invades the main body case 73 through the gap between the open hole portion 62 and the operation handle 20, the juice is operated by the operation handle. It flows down through the operation shaft 10 in the shaft part 23 of 20, or falls in a perpendicular direction at this space | interval. However, since the cap 40 is fitted between the operation knob 20 and the calorie control device 30 on the operation shaft, it is possible for the liquid to reach the calorie control device 30 by the cap 40. It is stopped. That is, the cap 40 is substantially occluded by the O-rings 50 and 51 of the outer fitting portion with the operation shaft 10, and is attached to the operation shaft 10 on the operation handle 20 side and flows through it. Falling juice is prevented from entering the calorie control device 30 by the blockage. In addition, since the cap 40 is formed to protrude radially outward, the liquid flowing down to the cap 40 is supported by the protrusion and flows downward from the upper right to the lower left of the cap 40 in the drawing. It is partitioned to flow down the control device (30). Then, the liquid flowed into the liquid receiving part (not shown) formed at the bottom of the main body case is received or discharged to the outside of the case.

In this way, the problem that the juice flowing from the manipulation handle 20 side flows directly into or reaches the calorie control device 30 is damaged. The shape, size, and the like of the cap 40 can be freely set in accordance with the arrangement of the calorie control device 30, the inclined state, or the size of the open hole portion 62 of the operation plate 60. In FIG. 1, since the calorie control device 30 provided in series with the operation shaft 10 is obliquely installed in the operation handle 20, the liquid flows through the gap between the open hole portion 62 and the shaft portion 23. As shown in FIG. Even if it is lowered or dropped, the cap 40 may be any arrangement, size, or shape capable of picking it up. Moreover, since the height position which attaches the cap 40 in the operation shaft 10 can be adjusted and set predetermined, you may arrange | position it closely to the open hole part 62 side, for example. Therefore, as can be seen from the above description, the size projecting in the radial direction in the cap 40 may be set larger than the projection shape of the calorific control device 30 viewed in the vertical direction.

The attaching procedure of the cap 40 to the operation shaft 10 is to fit the O-ring 50 of one side outward in the annular groove 11 of the operation shaft 10, and then the cap 40 is shown in FIG. In this case, the upper and lower portions of the ring may be fitted into the operation shaft 10, and the other O ring 51 may be externally fitted into the annular groove 11. The cap 40 is reliably fixed to the operation shaft 10 by the contracting force in the radial direction of the two O-rings and the clamping force on the cap 40, and the outer fitting portion is blocked.

According to the above embodiment, such a cap 40 is enough to fit outside the middle of the operation shaft 10, the assembly workability is improved, the cap 40 can be attached with a minimum attachment space As it is not bulky, the device can be simplified and compacted. As the calorie control device 30, for example, a gas cock for gas volume control is employed in the case of a gas stove, and a calorific switch for controlling the amount of electricity supplied to the heater in the case of an electric stove. In the former case, the ignition mechanism portion of the gas cock may be provided on the upper surface of the gas cock body, and according to the present embodiment, it is possible to reliably prevent dripping of soup or the like into the ignition mechanism portion. In the example of illustration, although a gas burner and a heater are connected to the calorie control device 30, they are abbreviate | omitted about them. As the calorie control device 30, in the various devices in which the operation knob is exposed on the upper surface of the operation plate as described above, it can be used as one having various switching functions in addition to the adjustment function.

FIG. 3 is an enlarged view of a main portion showing another embodiment in which the cap 40 is fixed to the operation shaft 10, and a part thereof is shown in cross section. Although the embodiment of FIG. 1 is a structure which is constricted by the two O-rings 50 and 51 fitted to the operation shaft 10 outside, the embodiment of FIG. 3 has the cap 40 by one O-ring 52. The case where it is fixed to this operation shaft 15 is shown. In the example of illustration, the lower end part 13 of which the diameter was expanded is formed in the lower part of the operation shaft 15, and the lower end of the cap 40 is supported by this end 13. As shown in FIG. Also in this embodiment, the inner diameter of the through hole 46 of the cap 40 is set slightly larger than the outer diameter of the operation shaft 15. An upper side of the end 13 of the operating shaft 15 is provided with an annular groove 12 on the same axis as the operating shaft 15, and the cap 40 is moved from the upper side to the lower side in FIG. 3. After letting it fit into (15), O-ring 52 is fitted in the annular groove 12 outside. As a result, the O-ring 52 abuts against the annular groove 12 and the top surface of the cap 40, and the contracting force in the radial direction of the O-ring 52 occludes the outer fitting portion. The cap 40 is pressed downward in the axial direction.

In addition, as the O-rings 50, 51, and 52 shown in FIGS. 1 and 3, elastic members formed of natural rubber or synthetic rubber (neobutylene rubber, neoprene rubber, silicone rubber, etc.) may be used. Instead of the ring, an annular elastic member made of, for example, a piano wire or spring steel may be used.

In the embodiment of FIG. 4 shown next, the operation knob 21, the operation shaft 10, and the calorie control device 30 formed successively are shown in the horizontal direction. The cap 41 is formed in the shape of an umbrella with its outer circumferential edge drooping. In the illustrated embodiment, when the juice flows downward or falls through the gap between the open hole portion 62 of the operation plate 60 and the shaft portion 24 of the operation handle 21, the liquid is adjusted to the calorie value. The cap 41 is prescribed so as not to directly reach the device 30. Specifically, the outer diameter D1 of the cap 41 was set larger than the outer diameter D2 of the calorie control device 30. That is, the shape and size of the cap 41 were made into the shape larger than the projection shape which the calorie control device 30 saw from the axial direction, ie, the shape and size which can cover the calorie control device 30. Therefore, the area where the juice flows or falls is supported by the cap 41, so that the juice directly reaches the calorie control device 30 is avoided.

According to the embodiment shown in FIG. 5, the cap 42 was directly fitted outside with respect to the operation shaft 10, without using the elastic fastening member like the O-ring already demonstrated. In this embodiment, the inner diameter of the through hole 49 of the cap 42 is set to the same dimension as the outer diameter of the operation shaft 10 or smaller than it. The cap 42 is made of an elastic member that contracts radially inwardly, for example, a synthetic resin material such as polyvinylcarbazole (PVC) in addition to the various rubber materials described above. The cap 42 is fixed to the operation shaft 10 by a reaction in which the operation shaft 10 presses and widens the through hole 49 when the cap 42 is externally fitted to the operation shaft 10. In addition, as shown in the figure, the annular groove 14 on the same axis as the axis is formed in the portion of the operation shaft 10 where the cap 42 is fitted outward, thereby facilitating the attachment of the cap 42 and determining the attachment position. do. As the cap 42 formed of such an elastic member becomes larger in size, its rigidity is lowered. Moreover, in addition to the umbrella shape as shown in the cap 42, the cross-sectional shape may be a wave shape or the like to improve rigidity. For example, as shown in FIG. It is also possible to employ only the inner side 44 having the through-hole fitted in the outer side 10) using the elastic material, and the outer periphery thereof integrally formed with a resin material or a metal material.

In the embodiment of FIG. 7 shown next, the case where two caps 47 and 48 are overlapped and formed on the operation shaft 10 is shown. This embodiment is in an inclined state as in the embodiment of Fig. 1, and the opening portion 62 of the operation plate 60 is large, so that the gap portion between the opening portion 62 and the shaft portion 25 of the operation handle 23 is also relatively large. Large case is shown. If there is a restriction on the protruding dimension of the cap, that is, the dimension projecting in the radial direction, a plurality of relatively small protruding caps as shown in the example can be used. In particular, it is suitable when the operating shaft 10 is inclined with respect to the vertical direction as shown in the illustrated example, and is arranged at a predetermined interval on the operating shaft 10 even if the projections of the caps 47 and 48 are small. By the relationship between the gap dimension and the inclination angle of the operating shaft 10, the projection dimension of the combination of the two caps 47 and 48 viewed in the vertical direction can be made substantially larger than that of the calorific control device 30. In this embodiment, the two caps 47 and 48 do not necessarily have to satisfy a predetermined shape and size in the same manner as in the above embodiment, respectively, and they may be combined to have a predetermined shape and size. Therefore, the device is simplified because no space is required.

In the above embodiment, any control device such as the calorific value control device 30 can be applied to the various operating devices via the operation shafts 10 and 15 by the operation handles 20 to 23. In that case, the operation knob can be used not only for the rotational movement but also for the movement in the axial direction, the swinging movement, or a combination thereof.

1 to 7, in the open hole portion 62 of the operation plate 60, an annular groove which is formed integrally with the operation plate 60 by extrusion processing and protrudes upward. 61). However, in embodiment described below, the operation plate is formed with the thick glass material, for example, and shows the structure which cannot form a protruding member like the said annular groove 61, or is difficult to form.

FIG. 8 shows yet another embodiment of the operating device, in which (a) is a sectional view of the main part centering on the operation knob 120, and (b) is a plan view of the operating shaft 110. As shown in FIG. In these figures, the open hole part 162 is formed in the operation plate 160 made of thick glass, and the axial part 123 of the operation handle 120 is fitted through this open hole part 162. The connection fixing of the operation knob 120 and the operation shaft 110 is fixed by forming the same axis hole 125 in the shaft portion 123 of the operation knob 120 and inserting the operation shaft 110 by press fitting or the like. do. The operation shaft 110 is a large diameter portion 114 having a larger diameter on the control device 130 side, and an axis diameter portion 112 having a smaller diameter on the operation handle 120 side. The side 112 is inserted into the shaft portion 123 of the operation knob 120. The outer diameter surface is milled on the shaft diameter portion 112, so that the D cut portion having a 'D' shape in cross section is engaged with the operation handle 120 side, thereby preventing the rotation of the operation handle 120 and fixing the rotation. Will be.

In order to prevent the juice penetrating through the opening hole 162 from reaching the control device 130, the cap 140 is fitted to the shaft diameter portion 112 of the operation shaft 110. The lower surface of the cap 140 is supported by the end 113 of the operation shaft 110, while the upper surface of the cap 140 to the lower end 129 of the shaft portion 123 of the operation handle 120 is installed toward the cap 140 Is pressed by. That is, the cap 140 is fixed between the operation knob 120 and the end 113 of the operation shaft 110. Therefore, since the cap 140 is easily fixed to the operation shaft 110 only by pressing the operation handle 120 into the operation shaft 110, a separate attachment member for fixing is not required and can be easily attached. Can be.

FIG. 9 shows yet another embodiment, in which (a) is a cross-sectional view of a main part centered on a portion of the manipulation knob 120, and (b) is a plan view of the manipulation shaft 110a. In these drawings, the operation shaft 110a is formed with a constant outer diameter from the control device 130 side toward the operation handle 120 side, and is formed into the hole 125 of the shaft portion 123 of the operation handle 120. The D cut portion 111a is formed at the portion to be inserted.

Also in this embodiment, the cap 140 is fixed to the operation shaft 110a by being pressed by the operation knob 120, but different from FIG. 8, the cap 140 is provided at the end portion 113a formed of the D cut 111a. It is fixed only by the support. That is, the cap 140 is fixed by the end 113a of the operation shaft 110a and the lower end 129a of the operation handle 120. Therefore, the rocking prevention and rotation fixing with respect to the operation knob 120 can be performed simply by forming the D-cut portion 113a on the operation shaft 110a, and the operation shaft 110a is end-shaped as shown in FIG.

That is, the cap 240 is different from the above embodiments in that the juice prevents the juice from reaching the calorie control device 30 and also forms the missing portion 242 to discharge the juice to the specific portion. Therefore, when a portion that is not desired to be discharged is specified in the apparatus, the defect portion 242 corresponding to this may be formed in advance in the cap 240.

In the illustrated embodiment, although the cap 240 is formed in a horizontal shape in the drawing, it may be formed obliquely as necessary and can be smoothly discharged through the defect part 242 by the weight of the juice. In that case, the juice is set to be discharged through a predetermined portion in advance with respect to the operation according to the operation of the operation knob. The missing portion 242 may be formed by drilling a hole in the bottom portion 243 of the cap 240 in addition to the illustrated example. In addition, while attaching the said cap 240 is applicable to all the attachment structures shown in the said embodiment, you may use it in combination as needed.

13 and 14 show yet another embodiment. These are different from the embodiment of FIGS. 1-12, and have shown the structure which neither of the cap 240 in embodiment mentioned above is provided. In order to prevent the liquid from reaching the calorie control device 330 through the open hole 362 of the operation plate 360, the annular wall 390 is attached to the open hole 362 in this embodiment. In particular, it is suitable when the operation plate 360 is formed of a thick glass material, that is, when it is difficult to form the annular wall 61 (Fig. 1, etc.) as in the above embodiment. The annular wall 390 of the present embodiment is formed of a material having flexibility and ductility by the various rubber materials or resin materials described above, and the annular protrusion 391 and the operation plate (protruding toward the operation knob 320 side). The engaging pieces 392 and 393 for clamping the 360 in the axial direction are provided. By setting the protrusion 391 to a predetermined height, it is difficult for the juice to ride over it, and thus reaching the calorie control device 330 through the opening hole 362 is prevented. The annular wall 390 is elastically deformed and can be easily attached to the open hole 362 of the operation plate 360, and once mounted, it is not detached by the locking pieces 392 and 393. In addition, since these locking pieces 392 and 393 are fixed in close contact with the operation plate 360, the liquid penetrates into the mounting inner side through the gap between the locking pieces 392 and 393 and the operation plate 390. Is prevented. Further, by making the protrusion 393 and the drooping wall 328 of the operation handle 320 into the insert shape, further intrusion of the juice into the device is prevented.
