Description

  The present invention relates to a fryer that is a cooking utensil for frying fish, meat, vegetables and the like with cooking oil.

As shown in FIG. 11, there is known a fryer 101 including a cabinet 102 having a tank 104 for storing cooking oil and a heater unit 103 detachably attached to the cabinet 102 ([Patent Document 1]). Such). Such a flyer 101 is called a simple type or a cassette type. When the heater unit 103 is attached to the cabinet 102, a heater portion 112 that is cantilevered from the heater unit 103 is disposed near the bottom of the tank 104. After that, the cooking oil in the tank 104 is heated to a predetermined temperature (about 150 to 180 degrees) by electrically generating heat from the heater unit 112, and the food is cooked. In addition, the temperature of cooking oil is controlled by the heater unit 103 so that it may become the predetermined temperature mentioned above. For this reason, a temperature sensor or the like is also attached to the heater unit 112.
Japanese Utility Model Publication No. 60-132228

  Since the heater unit 112 is cantilevered from the heater unit 103, the heater unit 103 is tilted, and the leading end of the heater unit 112 comes into contact with the bottom of the tank 104. Cheap. The heater unit 103 is fixed to the cabinet 102 by attaching the clip-like attachment portion provided on the side surface thereof to the attachment plate 107 of the cabinet 102. However, the gripping force of the clip-like attachment portion is not sufficient, and the heater unit 103 hangs down. It is easy to generate. When the sagging occurs, the tip of the heater unit 112 comes into contact with the bottom surface of the tank 104, so that the heat generated by the heater unit 112 is taken away by the tank 104 (cabinet 102), which is effective for raising the temperature of the oil and maintaining the temperature. The heat used is reduced.

  Therefore, as shown in FIG. 12, another member 105, 106 is attached to the tip of the heater unit 112 so that the heater unit 112 does not directly contact the bottom surface of the tank 104. Here, the angle member 105 is fixed to the lower surface of the heater unit 112 by sandwiching the tip of the heater unit 112 between the metal angle member 105 having an L-shaped cross section and the metal U-shaped plate 106. The bottom edge of the angle member 105 is brought into line contact with the bottom surface of the tank 104, thereby preventing the heater portion 112 from sagging.

  By providing separate parts in this way, direct contact between the tip of the heater portion 112 and the bottom surface of the tank 104 is prevented, and heat conduction is achieved by line contact (reduction in contact area) between the angle member 105 and the bottom surface of the tank 104. Although it is deterred, it has not completely prevented the escape of heat. For this reason, there is a possibility that energy sufficient for cooking the ingredients cannot be obtained, cooking time may be prolonged, and the frying may be worsened, and further improvement has been demanded. Further, since the temperature of the cabinet 102 (tank 104) rises due to the heat transmitted through the angle member 105, care must be taken in handling the cabinet 102 (tank 104).

  Furthermore, since the separate parts 105 and 106 are attached to the tip of the heater portion 112, there is a problem that the cleaning performance of the heater unit 103 is significantly deteriorated. That is, although fried residue etc. accumulate in the tank 104, these are likely to be clogged between the heater part 112 and the separate parts 105 and 106, and since the heater part 112 is at a high temperature, cleaning becomes difficult. Further, since the separate parts 105 and 106 are provided, there is an aspect that the raw material cost and the assembly cost increase. Accordingly, an object of the present invention is to provide a fryer that can reliably prevent the heater unit from sagging and can fully utilize the heat of the heater.

The fryer according to claim 1 is provided with a cabinet having a tank for storing cooking oil and a heater unit that is detachably attached to the cabinet, and the cabinet is a unit attachment in which the heater unit is attached. A heater unit disposed in the tank when mounted on the cabinet, a mounting hook for holding the unit mounting plate of the cabinet, and a lower end of the heater unit. A hook that extends in the direction in which the mounting hook is inserted, and a slit into which the hook is inserted when the heater unit is attached to the cabinet is formed near the lower end of the unit mounting plate.
A locking recess that can lock the locking claw is formed at the upper end of the unit mounting plate, and the heater unit is directed from the lower end of the unit mounting plate to the side while the locking claw is locked in the locking recess. The heater is held above the tank when placed on the extended unit support plate .
Note that “above the tank” as used herein does not mean that the heater section must be entirely outside the tank, but also includes a case where a part of the heater section is inside the tank. .

  According to a second aspect of the present invention, in the flyer according to the first aspect, the locking claw is formed by extending the lower end of the side plate to which the attachment hook of the heater unit is attached. It is characterized by being formed integrally with the face plate.

The invention described in claim 3 is the fryer according to claim 1 or 2, further and extended to the fall prevention plate to the bottom level near the cabinet downward from the outer end portion of the units the supporting plate It is characterized by having. Note that the fall prevention plate referred to here includes a cylindrical shape based on a plate-like portion and a simple rod-like shape.

According to the flyer of the first aspect, when the heater unit is attached to the cabinet, the attachment hook is attached to the unit attachment plate, and the locking claw is inserted into the slit. At this time, the locking claw and the slit are locked to each other, so that the inclination of the heater unit is reliably prevented. As a result, the heater unit tip of the heater unit does not come into contact with the tank bottom surface, and all the heat generated by the heater unit is utilized for raising the temperature of the oil in the tank or maintaining the temperature, and cooking can be suitably performed. . Moreover, since it is not necessary to provide another part etc. in a heater part, cleaning property is not deteriorated.
Furthermore, according to this flyer, when the heater unit is placed on the unit support plate while the locking claw is locked in the locking recess formed at the upper end of the unit mounting plate, the heater unit moves the heater portion upward. It will be placed diagonally in the lifted state. At this time, since the heater part is located above the tank, the oil adhering to the heater part drops into the tank below. Thus, when the heater unit is removed from the cabinet, the heater unit can be easily temporarily placed without soiling the surroundings with oil.

  According to the flyer according to the second aspect, since the locking claw is formed by extending the lower end of the side plate to which the mounting hook of the heater unit is attached, the cost increases when the locking claw is formed. Factors can be kept to a minimum (or there is virtually no cost increase). Further, since the locking claw is formed integrally with the side plate having sufficient strength for mounting the mounting hook, the locking claw has sufficient strength.

  According to the flyer of the third aspect, since the anti-tip plate extending from the outer end of the unit support plate to the vicinity of the bottom level is provided, it is possible to reliably prevent the cabinet from overturning. it can. In other words, the flyer has its center of gravity located at a position that tends to tilt toward the heater unit mounting portion due to the weight and position of the heater unit. For this reason, when the cabinet is tilted toward the heater unit mounting portion, the tipping prevention plate comes into contact with the flyer mounting surface before the tilt angle becomes large, and the tipping of the flyer is prevented. The fall prevention plate extends downward from the outer end of the unit support plate that extends outward, and comes into contact with the cabinet mounting surface at a position somewhat away from the center when the cabinet is tilted. The tilt of the can be stopped difficult to be effective. In addition, the unit mounting plate, the unit support plate, and the overturn prevention plate can be easily formed from a single metal plate, and can be formed with almost no increase in manufacturing cost.

  An embodiment of a flyer according to the present invention will be described below with reference to the drawings. FIG. 1 shows a side view of the fryer 1 in a state in which the cabinet 2 and the heater unit 3 are separated, and FIG. 2 is a perspective view of the fryer 1 in a state in which the heater unit 3 is attached to the cabinet 2 as viewed obliquely from above. Show. As shown in FIGS. 1 and 2, the flyer 1 of the present embodiment mainly includes a cabinet 2 provided with a tank 4 for storing oil, and a heater unit 3 that is detachably attached to the cabinet 2. As part. A stainless plate is used for most of the exterior of the flyer 1 in consideration of heat resistance and corrosion resistance.

  The cabinet 2 includes a detachable tank 4, and a pair of handles 5 are attached to upper ends on both sides of the tank 4. By holding the handle 5 and lifting the tank 4 upward, the tank 4 is separated from the main body of the cabinet 2 and the edible oil inside is discarded or purified. At the bottom of the cabinet 2, four legs 6 are attached to the four corners so as to form a space between the mounting surface and the flyer 1 firmly on the mounting surface. The legs 6 are heat-resistant rubber parts and are fixed to the bottom surface of the cabinet 2 main body by screws and screws.

  As shown in FIG. 3, a unit mounting plate 7 serving as a mounting portion of the heater unit 3 is attached to one side surface (side surface corresponding to the short side of the long side and the short side in plan view). A unit support plate 8 and an overturn prevention plate 9 are sequentially extended from the unit mounting plate 7 and will be described in detail later. The unit mounting plate 7 includes a pair of mounting portions 7a bent at both ends thereof, and the pair of mounting portions 7a are fixed to the side surface of the cabinet 2 main body. For this reason, the main part of the unit mounting plate 7 is arranged along the side surface of the cabinet 2 main body in a state where a gap is formed between the unit mounting plate 7 and the side surface of the cabinet 2 main body.

  Each mounting portion 7a is formed with two inverted U-shaped mounting holes 7b arranged in the vertical direction when viewed from the side. Each end of each mounting hole 7b is further bent upward, and a screw 7c is accommodated in this portion. The unit mounting plate 7 is fixed to the cabinet 2 body by a total of four screws 7c. The total four mounting holes 7b are not symmetrical with each other when viewed from the side, and are all oriented in the same direction. For this reason, the height of the unit mounting plate 7 can be adjusted in two stages by sliding the unit mounting plate 7 with respect to the side surface of the cabinet 2. In addition, the screw 7c of this embodiment is loosened when adjusting the height of the unit mounting plate 7, and is tightened after the height is adjusted.

  Moreover, the upper end of the unit mounting plate 7 is partly cut away, and a locking recess 7d is formed. From the lower end of the unit mounting plate 7 described above, a unit support plate 8 is extended substantially perpendicularly toward the outside. The unit support plate 8 supports the heater unit 3 from below and positions the heater unit 3 in the vertical direction when the heater unit 3 is mounted on the unit mounting plate 7. In addition, when the heater unit 3 is attached to the cabinet 2, the safety switch 17 protruding from the lower surface of the heater unit 3 is pushed into the unit housing 11 to allow the heater unit 3 to generate heat. There is also a role.

  A slit 10 is formed at a joint portion between the unit mounting plate 7 and the unit support plate 8. The slit 10 is parallel to the unit mounting plate 7. In the present embodiment, the unit support plate 8 is also parallel. Further, a fall prevention plate 9 is extended downward from the outer edge of the unit support plate 8. The fall prevention plate 9 extends to the vicinity of the bottom level (mounting surface level) of the cabinet 2. In addition, the lower end part of the fall prevention plate 9 is turned back for terminal processing. The unit mounting plate 7 (including the mounting portion 7a), the unit support plate 8, and the overturn prevention plate 9 are formed from a single metal plate.

  As shown in FIG. 4, the heater unit 3 attached to the cabinet 2 described above includes a box-shaped unit housing 11 in which an electric circuit is stored, and a cantilevered outward from the unit housing 11. An extended heater portion 12 is provided as a main component. A power cord (not shown) that supplies power for generating heat from the heater unit 12 is led out from the unit housing 11. Further, a temperature adjustment dial 13, a main switch 14, lamps 15 for notifying operation status, and the like are disposed on the side surface of the unit housing 11.

  Further, a handle 16 used for attaching / detaching the heater unit 3 to / from the cabinet 2 is attached to the upper surface of the unit casing 11, and the safety switch 17 described above is disposed on the lower surface. Further, a mounting hook 18 that is used when the unit housing 11 is mounted on the unit mounting plate 7 is mounted on the side surface of the unit housing 11 on which the heater portion 12 is projected. The mounting hook 18 has a spring property, and the heater unit 3 is fixed to the cabinet 2 by sandwiching the unit mounting plate 7 between the mounting hook 18 and the side surface of the unit housing 11.

  The heater portion 12 extends outward from the vicinity of the upper end portion of the unit housing 11 and immediately extends downward, and then extends horizontally. The heater unit 12 is introduced into the tank 4 from the upper end of the tank 4 and generates heat near the bottom of the tank 4 to warm the oil in the tank 4, thus having such a shape. The heater unit 12 has a heat generating portion arranged inside a stainless steel pipe, and the length of the heat generating portion is secured by meandering the horizontal portion several times. Both ends of the heater unit 12 are coupled to the unit housing 11. A temperature sensor 19 for detecting the temperature of the edible oil in the tank 4 is also attached to the heater unit 12.

  Furthermore, a locking claw 20 corresponding to the slit 10 is provided at the center of the lower end of the side surface of the unit housing 11 where the heater portion 12 extends. The locking claw 20 extends from the lower end of the side surface of the unit housing 11 in the insertion direction of the mounting hook 18. The locking claw 20 is formed by folding and spot welding a metal plate that constitutes the side surface of the unit housing 11. For this reason, when the latching claw 20 is formed, the factor that increases the cost is kept to a minimum (or does not substantially increase the cost). In addition, the metal plate of the side surface in which the latching nail | claw 20 is formed uses the thing thicker than other parts in consideration of intensity | strength in order to attach the attachment hook 18. FIG. For this reason, the latching claw 20 formed by folding this back has sufficient strength.

  As described above, in this embodiment, the slit 10 is formed in the lower end portion of the unit mounting plate 7 (here, the joint portion with the unit support plate 8) and the lower end of the fixing side surface of the mounting hook 18 of the heater unit 3 is engaged. A pawl 20 is formed. By doing so, the mounting hook 18 is inserted into the unit mounting plate 7 to be locked, and at the same time, the locking claw 20 is locked to the slit 10 so that the side surface of the unit housing 11 and the surface of the unit mounting plate 7 are connected. It is possible to reliably prevent the “sagging” state in which the heater unit 3 is tilted by being substantially interviewed. Since the inclination of the heater unit 3 is reliably prevented, the heater unit 12 is held in a state of floating in oil near the bottom of the tank 4. As a result, all the heat generated from the heater unit 12 is transmitted to the oil in the tank 4.

  Further, since no separate parts or the like are attached to the heater section 12, the cleaning performance of the heater unit 3 is not deteriorated. Furthermore, regarding the formation of the slit 10 and the locking claw 20 described above, it is possible to cope with a change in the shape of a part of an existing part, and it is possible to minimize the cost increase or substantially. Cost does not increase. Furthermore, in this embodiment, the fall prevention plate 9 is also provided as described above. A side view of the conventional flyer 101 is shown in FIG. The center of gravity of the flyer 101 is biased toward the heater unit 103, and it can be said that the flyer 101 tends to fall in the direction indicated by the arrow in the figure. If the cooking oil is not enough in the tank of the cabinet 102, it will be more likely to fall.

  Further, the fryer 101 may be attached with an oil drainer 108 or the like in which the cooked food is placed. The oil drain 108 is often located above the unit housing 11 in terms of arrangement (obstructs when it is in front and interferes with other devices etc. when it is on the side). In such a case, the flyer 101 is It becomes easier to fall. In the case of the present embodiment, since there is the fall prevention plate 9 as described above, the tip of the fall prevention plate 9 comes into contact with the mounting surface of the flyer 1 as soon as the flyer 1 is about to fall, and the fall is suppressed. . Even when the fall prevention plate 9 is provided, it is possible to cope with a change in the shape of a part of an existing part, and it is possible to minimize the cost increase or not substantially increase the cost. .

  Furthermore, in this embodiment, a locking recess 7 d is formed at the upper end of the unit mounting plate 7. Here, as shown in FIGS. 8 and 9, when the heater unit 3 is placed on the unit support plate 8 while the locking claw 20 is locked to the locking recess 7 d, the heater unit 12 is attached to the tank 4. It is held obliquely upward. For this reason, it is possible to easily drain the heater 12. For example, after cooking using the fryer 1, the oil in the tank 4 is drained. At this time, the power supply is turned off and the heater unit 3 is removed from the cabinet 2. However, a large amount of oil is attached to the heater unit 12 and the temperature is high.

  If placed on a workbench, the workbench is soiled with oil and requires further cleaning. The same is true if a cloth is laid. In addition, edible oil is often reused after removing the frying residue, but if the oil is wiped off, the amount that can be reused decreases. In the present embodiment, as described above, the heater portion 12 can be held on the upper portion of the tank 4 by the locking recess 7d, so that the heater portion 12 can be easily drained. In particular, in this embodiment, the locking recess 7 d is formed at the upper end of the unit mounting plate 7, so that when the heater unit 3 is placed on the unit support plate 8, the heater portion 12 is inclined. When held obliquely in this way, the dripping of the oil adhering to the heater unit 12 is promoted.

  After the energization of the heater unit 3 is stopped, the oil cannot be drained or purified (removal of frying waste) until the temperature of the oil in the tank 4 drops to some extent. If so, the dripping of the oil adhering to the heater 12 into the tank 4 is completed by the time the temperature of the oil is lowered. At this time, since the liquid drops from the bent portion of the heater portion 12, no oil adheres to the unit housing 11. Furthermore, the flyer 1 of this embodiment can adjust the mounting height of the unit mounting plate 7 as described above. By adjusting the mounting height of the unit mounting plate 7, the height of the heater section 12 in the tank 4 can be changed. FIGS. 10A and 10B show a state where the height of the heater section 12 in the tank 4 is changed in two stages.

  In the case of frying food covered with bread crumbs, a very large amount of fried residue is generated by the bread crumbs dropped from the ingredients. Since this fried residue accumulates at the bottom of the tank 4, if the heater 12 is near the bottom, the heater 12 is immediately buried in the fried residue. If it becomes like this, the fried residue will be heated excessively, and the fried residue will be burnt and carbonized, leading to early deterioration of the oil. Further, the fried residue is lifted by the convection generated by the heating by the heater unit 12 and adheres to the food. In such a case, a cold zone is provided below the heater portion so that the fried residue accumulates in the cold zone below the heater portion to avoid the above-described problems.

  In the case of the present embodiment, the height of the heater portion 12 in the tank 4 can be changed by adjusting the mounting height of the unit mounting plate 7, so that it is necessary to provide a cold zone according to the foodstuff. It can be easily handled even in cases. When it is not necessary to provide a cold zone, as shown in FIG. 10A, the heater 12 is placed near the bottom of the tank 4 by setting the mounting height of the unit mounting plate 7 at a lower position. Deploy. By doing in this way, the oil warmed by the heater part 12 convects the whole in the tank 4, and the whole oil in the tank 4 is warmed.

  On the other hand, when it is necessary to provide a cold zone, as shown in FIG. 10B, by installing the mounting height of the unit mounting plate 7 at an upper position, the cold zone Z is provided below the heater portion 12. To form. If it does in this way, only the oil mainly located above the heater part 12 will be heated, producing a convection, and the oil of a cold zone will not be warmed very much. Since the fried residue accumulates in a cold zone below the heater section 12 in a state where it is difficult to scorch, the above-described problems are unlikely to occur. As described above, the adjustment of the mounting height of the unit mounting plate 7 is realized by the shape and arrangement of the mounting holes 7b formed in the mounting portion 7a.

  In addition, the flyer of this invention is not limited to embodiment mentioned above. For example, in the embodiment described above, the locking claw 20 extends in the insertion direction of the mounting hook 18 from the lower end of the side surface to which the mounting hook 18 is fixed, but extends in the insertion direction from the lower end of the heater unit 3. It only has to be done. For example, the locking claw may be formed at the lower end of the side surface other than the side surface to which the mounting hook 18 is fixed, or may be formed at the lower end of the heater unit by bending a part of the bottom plate of the heater unit. May be.

  Further, regarding the invention according to the first aspect, the unit support plate 8 and the fall prevention plate 9 are not necessarily provided. If a slit into which a locking claw is inserted when the heater unit is attached is formed in the vicinity of the lower end of the unit attachment plate, sagging can be prevented. However, it goes without saying that it is preferable to provide the unit support plate 8 and the overturn prevention plate 9. Moreover, although it is preferable that both the fall prevention plate 9 and the locking recess 7d are provided, it is of course possible to adopt only one of them.
