Description

  The present invention relates to a flyer heater swing-up mechanism in which a heater is disposed in a swing manner in an oil tank or can be freely taken out.

As a fly-up swing-up mechanism for arranging a heater in an oil tank in a swing manner or taking it out of the oil tank, techniques as shown in Patent Documents 1 and 2 are known. In the flyer swing-up mechanism described in Patent Document 1, a stand is disposed opposite to the upper surface of the fryer body, both end surfaces of the heater box are pivotally supported, and the heater is horizontally moved from the lower front side of the heater box. Then, it is bent substantially vertically downward, and further bent horizontally so that the heater is interposed in the oil tank. A handle is extended in the horizontal direction on the front side of the heater box, and the heater can be pulled up from the oil tank or disposed in the oil tank.
The flyer swing-up mechanism described in Patent Document 2 is designed to increase the length of the handle described in Patent Document 1.
JP-A-6-125847 Japanese Patent No. 2873369

  The technique of Patent Document 1 has a drawback that the length of the handle is short, and a considerable force is required to swing up the heater box and the entire heater. In the technique of Patent Document 2, the length of the handle is sufficient for swinging up the heater box and the heater, and it is possible to swing up with a light operating force. However, since the handle of Patent Document 2 is a fixed type and always exists in a long state, the handle is long when the tempura or deep-fried food is used with the heater in the oil tank. However, there was a problem that it interfered with fried food work.

  The present invention has been improved and removed in view of the above-described problems, and is intended to ensure a stable operation of the swing-up mechanism.

Thus, in order to solve the above-mentioned problems, the means of claim 1 adopted by the present invention is a flyer in which the heater is a swing type, and the heater can be disposed in or taken out of the oil tank. In the above, an extendable handle for rotating the heater includes a lever having a root portion fixed to a heater box extending the heater, and a bottomed cylindrical handle slidably fitted to the lever. The lever is slidably inserted in the center hole of the plate fixed to the end face on the back side of the handle, and gradually increases in diameter toward the front side on the outer peripheral surface near the end face on the near side of the lever. The large diameter bulging part, which is larger than the diameter of the center hole of the plate, holds the restraint state that restrains the movement of the handle relative to the lever when engaged with the center hole of the plate, and is attached to the front end surface of the lever Is Stopper, fryer heater swing-up mechanism, characterized in that is adapted to hold the engagement state in contact with the wall surface of the interior of an empty cavity that bulges provided on the proximal end of the handle which are It is.

  Thus, in the first aspect of the invention, the length of the handle for rotating the heater is extendable. Therefore, when taking out the heater from the oil tank (swing-up), if the length of the handle is increased, the swing-up operation can be easily performed by the lever principle. Also, when the heater is placed in the oil tank and heating is in use, if the length of the handle is shortened, the work of tempura, fried food, etc. will not be hindered.

  The configuration of the present invention will be described below based on the embodiment of the invention shown in the drawings. 1 to 4 relate to an embodiment of the present invention. FIG. 1 is a schematic perspective side view showing the entire fryer 1 in a normal state. FIG. 2 is a telescopic view comprising a lever 2 and a handle 3. The handle 4 is shown, in which FIG. (A) is a longitudinal sectional view in a contracted state, and FIG. (B) is a longitudinal sectional view in an expanded state. FIGS. 3A to 3C are schematic side views showing respective processes when the heater box 5 swings up, and FIGS. 4A to 4C show the swing down of the heater box 5. It is a schematic side view which shows each process of time.

  As shown in FIG. 1 showing a normal state, the heater box 5 is rotated on both rear side surfaces by a pivot (not shown) of the stand 7 on the rear side (right side in FIG. 1) upper surface of the fryer body 6. It is pivotally supported. The center of rotation of the heater box 5 is at a position eccentric to the upper side on the rear side. The front side of the heater box 5 (the left side in the figure) protrudes upward from the oil tank 8 in an overhang shape, and the heater support portion 9 extends straight downward from the protruding lower surface facing the oil tank 8. Subsequently, the heater 10 is bent approximately 90 degrees and the heater 10 is extended in the horizontal direction to the front side.

  Thus, in the fryer 1 of the present embodiment, the pivot points at both ends of the heater box 5 are eccentric toward the rear upper side, and the front end face side of the heater box 5 protrudes overhanging toward the oil tank 8 side. I am letting. Therefore, the heater 10 can be extended directly from the lower surface side of the heater box 5, and the substantial thickness of the rear side of the fryer body 6 is reduced by that amount, while the size of the oil tank 8 is increased. Can do. Thereby, when it is going to secure the oil tank 8 of a fixed capacity | capacitance, it is possible to make the whole size of the fryer 1 far smaller than the technique of the patent documents 1 and 2 of the past.

  On the other hand, a handle 4 comprising a lever 2 and a handle 3 is attached to the right side surface of the heater box 5 along the right side surface direction of the fryer body 6. In the handle 4, a root portion 2 </ b> A bent in an L shape of the lever 2 is fixed to the right side surface of the heater box 5. As shown in FIGS. 2A and 2B, the handle 4 has a bottomed cylindrical handle 3 slidably fitted on the lever 2. A donut-shaped plate 11 is fixed to the end face on the back side of the handle 3, and the lever 2 is slidably inserted into the center hole thereof. On the outer peripheral surface near the end surface on the near side of the lever 2, an enlarged diameter portion 12 is formed which is crushed by press work and expanded in diameter. The enlarged diameter portion 12 is formed to be larger than the diameter of the central hole of the plate 11 of the handle 3, and the lever 2 is engaged when the enlarged diameter portion 12 is engaged with the central hole of the plate 11. The movement of the handle 3 with respect to is restricted, and this restricted state is maintained.

  A stopper 13 is attached to the front end surface of the lever 2. The stopper 13 abuts against the wall surface of the bulged inner cavity portion 14 provided at the front side end portion of the handle 3 and restrains the movement of the handle 3 relative to the lever 2. At this time, after the handle 3 is engaged with the stopper 13 by making the outer diameter dimension of the stopper 13 slightly larger than the dimension of the inner wall surface of the cavity portion 14 of the portion engaged with the stopper 13, It is possible to keep the engaged state.

On the other hand, on the upper side of the rear side of the left and right end faces of the heater box 5, the long side of the rear side of the stopper 15 that is framed in a rectangular shape that holds the state when the heater box 5 is swung up is pivotally supported. ing. The length dimension of the long side of the stopper 15 is set to be substantially the width dimension of the oil tank 8, and the length dimension L of the short side on the right side of the stopper 15 is from the upper surface of the heater box at the pivot center point of the stopper 15. It is set to be longer than the height dimension H. Furthermore, a hook 16 for a user to hook his / her finger is integrally attached to the right short side of the stopper 15. A plate-like locking piece 17 that is bent in a dogleg shape that can be engaged with the long side of the front side of the stopper 15 is fixed to the rear upper surface of the right end side of the fryer body 6. . The length of the locking piece 17 is set to be smaller than the width of the oil tank 8 so that it can enter the inside of the stopper 15 framed in a rectangular shape.
In the state shown in FIG. 3A, the stopper function for restricting the counterclockwise rotation of the heater box 5 is brought into contact with the oil tank wall surface on the heater support portion 9 constituting the vertical surface portion of the heater. You may make it provide a contact member.

Next, how to use the fryer 1 according to this embodiment will be described. First, when using tempura with fryer 1 or frying, the state shown by the chain line in FIG. 1, as shown in FIG. 2 (A) and FIG. 3 (A), The heater 10 is in the oil tank 8 and heats the oil. At this time, the heater box 5 and the handle 4 are in a horizontal state, the handle 3 of the handle 4 is pushed into the lever 2 as far as it will go, and the stopper 13 abuts against the bottom end surface of the cavity portion 14 and is held in this position. Has been. In this way, when used, the handle 4 has the shortest dimension in a contracted state, so that the operation of the deep-fried food is not hindered.
At this time, the stopper 15 of the heater box 5 is in contact with the upper surface of the rear portion of the fryer body 6 at a position behind the locking piece 17 so that the heater box 5 is counterclockwise from the state of FIG. This is regulated by a relationship of L> H so as not to rotate. This is to prevent the support portion 9 of the heater 10 from interfering with the oil tank wall surface.

  When the heater 10 is swung up from this use state and the oil in the oil tank 8 is changed or cleaned, the handle 3 of the handle 4 is pulled forward as shown in FIG. Slide the lever 2 up to the maximum dimension. At this time, the plate 11 attached to the rear side end face of the handle 3 rides on and engages with the enlarged diameter portion 12 provided near the front side end of the lever 2, and this state is maintained. Thereafter, the handle 4 is gripped by the handle 4 with the maximum dimension, and is rotated clockwise in FIGS. By this turning operation, the entire heater 10 and the heater box 5 are turned around the pivot point of the stand 7, and the heater 10 is pulled up from the oil tank 8. Since the handle 4 has the maximum size, a force (rotational moment) required for the pulling is small, and the pulling can be easily performed.

  As the swing-up operation is performed, the rectangular stopper 15 attached to the heater box 5 gradually turns toward the front side so as to trace the upper surface of the locking piece 17 as the heater box 5 rotates clockwise. It moves to (the left side of each figure of FIG. 3), gets over the upper surface side of the locking piece 17 as it is, and falls by its own weight (state (C) of the figure). Note that FIG. 3B shows the state in which the stopper 15 has passed over the locking piece 17 over. As shown in FIG. 5C, after the stopper 15 gets over the locking piece 17 and falls due to its own weight, the long side on the near side enters the front side of the locking piece 17 and the locking piece 17 And the upper surface of the fryer body 6. For this reason, even when the handle 4 of the handle 4 is released, the heater box 5 and the heater 10 are restricted from rotating counterclockwise in FIG. Thereafter, the oil in the oil tank 8 may be replaced or maintained.

  On the other hand, when the heater 10 is placed in the oil tank 8 by swinging down from the swing-up state, first, the handle 3 of the handle 4 is gripped from the state shown in FIG. The hook 16 integrally attached to the hook 16 is hooked with the finger of the other hand and pulled upward in the clockwise direction. As shown in the figure (B) of the same figure, as shown in FIG. Release the engagement. Then, from this state, the handle 3 and the hook 16 are rotated counterclockwise to lower the heater box 5 and the stopper 15. At this time, the stopper 15 is rotated integrally with the heater box 5 while being pulled up by the hook 16, so that the long side on the front side of the stopper piece 17 is as shown in FIG. It turns around to the back side and does not interfere with this.

  Further, when it is further rotated counterclockwise, it returns to the state shown in FIG. 3A, and the long side on the near side of the stopper 15 comes into contact with the rear upper surface of the fryer body 6. At this time, after the pivoting fulcrum of the heater box 5 is in the upper position and closer to the front side than the pivoting point of the stopper 15, the heater box 5 The above counterclockwise rotation is restricted and the state shown in FIG. 3A is maintained. In other words, it is possible to use tempura or fried food.
