[0003] [Patent Document 1] International Publication No. 2020 / 110669 [Patent Document 2] Patent No. 7051055 Summary of the Invention [Problem to be solved by the invention]
[0004] When cooking is completed in a fryer, the fryer is cleaned. Cleaning is generally carried out according to the following steps. First process: The frying oil is cooled and then drained from the oil tank. - Second process: Water is poured into the oil tank. Third process: Boil the water in the oil tank. · Fourth process: Add detergent to the oil tank. · Fifth work process: The inside of the oil tank is cleaned. - Sixth process: Rinse the oil tank. - Seventh work process: Drain the oil tank. The frying oil is cooled by natural cooling, which takes time to wait for the oil to cool, and the inside of the oil tank is cleaned by scrubbing, which takes time and effort, so cleaning requires a great deal of time and effort. In the fryer shown in Patent Document 1, the frying oil is cooled from outside the oil tank through the oil tank, while in the fryer shown in Patent Document 2, the frying oil is cooled by cooling air that naturally flows above the frying oil.
[0005] The present invention provides a fryer that can reduce the time required for cleaning. [Means for solving the problem]
[0006] The fryer according to the present invention comprises: The fryer is equipped with an oil tank for storing frying oil, a fryer body having a heating section located inside the oil tank for heating the frying oil, and an oil tank lid that is detachably placed over the oil tank to cover the oil tank, and the oil tank lid is provided with a cooling fan that supplies cooling air toward the frying oil in the oil tank when the oil tank lid is placed over the oil tank, and an exhaust port that allows exhaust from the inside of the oil tank lid to the outside.
[0007] According to this configuration, by using the oil tank lid, cooling air is forcibly supplied to the frying oil by the cooling fan, and the cooling air that has cooled the frying oil is then discharged to the outside of the oil tank lid through the exhaust port, where it is cooled by the cooling air. In addition, by forcibly supplying cooling air to the frying oil, ripples are generated in the frying oil, increasing the area of the frying oil that is exposed to the cooling air, thereby efficiently exchanging heat between the frying oil and the cooling air. In other words, the oil is cooled more efficiently by the cooling air flowing outside the oil tank than by cooling through the oil tank, and also more efficiently than by cooling by the cooling air naturally flowing above the frying oil, thereby shortening the cooling time and therefore the cleaning time.
[0008] In the present invention, It is preferable that a cleaning device be provided which is detachable from the fryer body and which, when attached to the fryer body, discharges a cleaning liquid into the oil tank to clean the inside of the oil tank.
[0009] According to this configuration, by using the cleaning device, the oil tank is automatically cleaned by the cleaning device, which shortens the cleaning time and eliminates the need for special cleaning operations, thereby shortening the time and reducing the effort required for cleaning work.
[0010] In the present invention, The cleaning device preferably includes a cleaning nozzle that ejects a cleaning liquid toward the heating unit.
[0011] According to this configuration, the heating section, which is prone to oil adhesion, is cleaned by ejecting cleaning liquid, which reduces the cleaning time and eliminates the need for special cleaning operations, thereby reducing the time and labor required for cleaning work.
[0012] In the present invention, It is preferable that the cleaning nozzle is provided so that its direction can be adjusted.
[0013] According to this configuration, efficient cleaning can be achieved by adjusting the direction of the cleaning nozzle so that the cleaning liquid can reach areas with a lot of oil, thereby shortening the cleaning time and the cleaning work time.
[0014] In the present invention, Preferably, the cleaning nozzle is provided so as to be rotatable.
[0015] According to this configuration, the rotation of the cleaning nozzle allows the cleaning liquid to be supplied over a wide range of the heating section, enabling efficient cleaning, thereby shortening the time required for cleaning and therefore the time required for cleaning work.
[0016] In the present invention, It is preferable that the oil tank lid is provided with a cleaning device support part that detachably supports the cleaning device, and that the cleaning device is supported on the cleaning device support part and attached to the fryer body by placing the oil tank lid over the oil tank.
[0017] With this configuration, cleaning can be performed while preventing the cleaning liquid from splashing outside the oil tank using the oil tank lid, so the cleaning liquid can be powerfully discharged to perform cleaning efficiently, thereby shortening the cleaning time and cleaning work time.The oil tank lid used for cooling the frying oil can be used as the oil tank lid when cleaning the oil tank, so it is inexpensive.
[0018] In the present invention, It is preferable to provide a fan cover that can be switched between a covered state in which the cooling fan is covered from the inside of the oil tank lid and a cover-released state in which the cooling fan is uncovered.
[0019] With this configuration, when cleaning the oil vat, the same oil vat lid as when cooling the frying oil is used, but by switching the fan cover to the cover position, the fan cover can prevent oil scattered from the oil vat from adhering to the cooling fan.By preventing oil from adhering to the cooling fan, the cleaning liquid can be powerfully discharged to perform cleaning efficiently, shortening the cleaning time and reducing the cleaning work time.
[0020] In the present invention, It is preferable that an exhaust port cover be provided that can open and close the exhaust port.
[0021] With this configuration, when cleaning the oil vat, the same oil vat lid as when cooling the frying oil is used, but by closing the exhaust port with the exhaust port lid, the exhaust port lid can prevent oil that has splashed out of the oil vat from splashing out to the outside through the exhaust port.By preventing oil from splashing out, the cleaning liquid can be powerfully discharged to perform cleaning efficiently, shortening the cleaning time and reducing the cleaning work time.
[0022] In the present invention, The heat dissipation member is provided with a heat absorption fin section and a heat dissipation section connected to the heat absorption fin section and through which heat is transferred from the heat absorption fin section, and it is preferable that the heat dissipation member is configured so that the heat absorption fin section is placed in the frying oil in the oil tank and the heat dissipation section is located above the oil surface of the frying oil in the oil tank.
[0023] According to this configuration, when cooling the frying oil, the heat of the frying oil is absorbed by the heat-absorbing fins and transferred to the heat-dissipating section by using the heat-dissipating member, and the cooling air from the cooling fan hits the heat-dissipating section to cool it. That is, the frying oil is cooled not only by the cooling air hitting the frying oil, but also by the heat-dissipating member, so the frying oil is cooled efficiently. Efficient cooling of the frying oil shortens the cooling time of the frying oil and shortens the time required for cleaning.
[0024] In the present invention, It is preferable that a second oil tank lid different from the oil tank lid is provided, the cleaning device is supported by the second oil tank lid, and the second oil tank lid is attached to the fryer body by covering the oil tank.
[0025] According to this configuration, the cleaning device can be attached to the fryer body simply by placing the second oil tank lid over the oil tank, so it does not take much time to prepare for the cleaning work, and the time required for the cleaning work can be shortened.

When the fan cover 13 is closed, it is in a covering state, covering the cooling fan 11 from inside the first oil tank lid 10, and when it is opened, it is in an uncovered state, uncovering the cooling fan 11. In this embodiment, the fan cover 13 can be swung open and closed, but this is not limiting and it may also be opened and closed by sliding or by detachment.
[0036] The exhaust port cover 14 is configured to open and close the exhaust port 12 . More specifically, as shown in Figure 4, the exhaust port lid 14 is supported inside the first oil tank lid 10 so that it can swing open and closed around a lid support shaft 14a attached inside the first oil tank lid 10. The exhaust port lid 14 closes the exhaust port 12 when closed, and opens the exhaust port 12 when opened. In this embodiment, the exhaust port lid 14 is provided inside the first oil tank lid 10, but it may also be provided outside the first oil tank lid 10. In this embodiment, the exhaust port lid 14 can swing open and closed, but this is not limited thereto; it may also be opened and closed by sliding or by detachment.
[0037] [Cleaning device] As shown in Fig. 7, the cleaning device 20 is configured to be detachably attached to the fryer body 1, and to discharge a cleaning liquid into the oil vat 3 to clean the inside of the oil vat 3. The cleaning device 20 can be attached to or detached from the fryer body 1 by covering the oil vat 3 with the first oil tank lid 10, which detachably supports the cleaning device 20 on a cleaning device support part 15 (see Figs. 3, 4, and 7) provided on the first oil tank lid 10.
[0038] More specifically, as shown in FIG. 5 , the cleaning device 20 includes five cleaning pipes 21 extending in the vertical direction of the oil tank. A cleaning nozzle 22 is provided at the bottom end of each of the five cleaning pipes 21. The five cleaning pipes 21 are held by cleaning liquid supply pipes 23 connected to the top ends of the cleaning pipes 21. The five cleaning pipes 21 are positioned by the cleaning liquid supply pipes 23 so that they are spaced apart at set intervals inside the oil tank 3. In this embodiment, the five cleaning pipes 21 are positioned so that one of the five cleaning pipes 21, the first cleaning pipe 21a, is located at the center of the oil tank 3, and two of the five cleaning pipes 21, the second cleaning pipes 21b, and two of the five cleaning pipes 21, the third cleaning pipes 21c, are located closer to the outer periphery of the oil tank than the first cleaning pipe 21a. While the present embodiment includes five cleaning pipes 21, the number of cleaning pipes 21 is not limited to this, and four or fewer or six or more cleaning pipes 21 may be provided.
[0039] As shown in FIG. 5, the cleaning liquid supply pipe 23 includes a first supply pipe section 23a, a second supply pipe section 23b, and a third supply pipe section 23c. The first supply pipe section 23a is connected to one first cleaning pipe 21a and holds the first cleaning pipe 21a. The second supply pipe section 23b is connected to two second cleaning pipes 21b and holds the two second cleaning pipes 21b. The third supply pipe section 23c is connected to two third cleaning pipes 21c and holds the two third cleaning pipes 21c. The second supply pipe section 23b and the third supply pipe section 23c are connected to the first supply pipe section 23a and held by the first supply pipe section 23a. A cleaning liquid introduction section 23d is connected to the first supply pipe section 23a.
[0040] 3 and 4, the cleaning device support part 15 provided on the first oil tank lid 10 is provided in a position between the cooling fan 11 and the exhaust port 12 of the first oil tank lid 10. The cleaning device support part 15 has mounting holes 15a drilled through the first oil tank lid 10 at five locations.
[0041] The five cleaning pipes 21 of the cleaning device 20 are inserted into the mounting holes 15a from above the first oil tank lid 10, and the cleaning liquid supply pipe 23 is received and supported from below by the support part 10a provided on the first oil tank lid 10, so that the cleaning device 20 can be attached to the cleaning device support part 15 and supported by the first oil tank lid 10. The cleaning device 20 can be detached from the cleaning device support part 15 and removed from the first oil tank lid 10 by pulling the five cleaning pipes 21 upward through the mounting holes 15a.
[0042] When cooking is finished in a fryer, the fryer is cleaned. Cleaning is performed in accordance with the following steps: a first step of cooling the frying oil 8 and discharging it from the oil tank 3; a second step of pouring water into the oil tank 3; a third step of boiling the water in the oil tank 3; a fourth step of pouring detergent into the oil tank 3; a fifth step of washing the inside of the oil tank; a sixth step of rinsing the inside of the oil tank; and a seventh step of draining the oil tank 3.
[0043] When the frying oil 8 is cooled in the first work step, the first oil tank lid 10 can be used for cooling. That is, as shown in Figure 6, the first oil tank lid 10 is placed over the oil tank 3 and fixed to the edge 3a of the oil tank 3. The fan cover 13 is in the uncovered state to allow the supply of cooling air by the cooling fan 11, and the exhaust port lid 14 is open to allow exhaust through the exhaust port 12. The cooling fan 11 is then driven. The cooling air is then forcibly supplied toward the frying oil 8 by the cooling fan 11, cooling the frying oil 8 with the cooling air. By forcibly supplying the cooling air toward the frying oil 8, the cooling air causes ripples in the frying oil 8, increasing the area of the frying oil 8 that is exposed to the cooling air, thereby cooling the frying oil 8 in a state where heat exchange between the cooling air and the frying oil 8 is efficiently carried out. The cooling air that has cooled the frying oil 8 flows out of the first oil tank lid 10 through the exhaust port 12.
[0044] When cooling the frying oil 8 in this manner, it is preferable to close the mounting hole 15a of the cleaning device support part 15 in the first oil tank lid 10 with a rubber cap or the like.
[0045] When the inside of the oil tank is washed in the fifth work step, the washing device 20 can be used to automatically wash the inside of the oil tank. That is, as shown in FIG. 7, the cleaning device 20 is attached to and supported by the first oil tank lid 10, which is attached and fixed to the fryer body 1. The cleaning liquid inlet 23d of the cleaning liquid supply pipe 23 is connected to a cleaning liquid supply source (not shown). The cleaning liquid supply source is a water supply or a detergent pump that discharges detergent liquid. When the inlet valve 24 (see FIG. 5) provided in the cleaning liquid inlet 23d is opened, the cleaning liquid from the cleaning liquid supply source is supplied to the first supply pipe 23a through the cleaning liquid inlet 23d, and is then supplied from the first supply pipe 23a to the second supply pipe 23b and the third supply pipe 23c. The cleaning liquid supplied to the first supply pipe 23a is supplied to the first cleaning pipe 21a and discharged from the cleaning nozzle 22. The cleaning liquid supplied to the second supply pipe 23b is supplied to the two second cleaning pipes 21b and discharged from the cleaning nozzles 22 of each second cleaning pipe 21b. The cleaning liquid supplied to the third supply pipe section 23c is supplied to the two third cleaning pipes 21c and discharged from the cleaning nozzles 22 of each third cleaning pipe 21c. Of the cleaning nozzles 22 of the five cleaning pipes 21, the cleaning nozzles 22 positioned corresponding to the heating section 4 discharge the cleaning liquid toward the heating section 4 to clean the heating section 4. Of the cleaning nozzles 22 of the five cleaning pipes 21, the cleaning nozzles 22 positioned corresponding to the oil tank interior 3b away from the heating section 4 discharge the cleaning liquid toward the oil tank interior 3b to clean the oil tank interior 3b.
[0046] When using the cleaning device 20, the fan cover 13 is switched to the cover state, and the fan cover 13 prevents the cleaning liquid scattered from the oil tank 3 from adhering to the cooling fan 11. In addition, the exhaust port lid 14 is closed, and the exhaust port lid 14 prevents the cleaning liquid scattered from the oil tank 3 from splashing out to the outside through the exhaust port 12.
[0047] [Heat dissipation member] As shown in FIG. 8, when the frying oil 8 is cooled, the cooling of the frying oil 8 can be accelerated by using a heat dissipation member 30.
[0048] 8, the heat dissipation member 30 includes a heat absorption fin section 31 having a plurality of heat absorption fins 31a, and a heat dissipation section 32 connected to the upper part of the heat absorption fin section 31. The heat dissipation section 32 is formed in a plate shape.
[0049] 8, the heat dissipation member 30 is configured to be used by placing the heat absorption fin section 31 on the heating section 4, and in use, the heat absorption fin section 31 is received and supported by the heating section 4 so that the heat absorption fin section 31 is placed in the frying oil 8 in the oil vat 3 and the heat dissipation section 32 is positioned above the oil level 8a of the frying oil 8 in the oil vat 3. In this embodiment, the heat dissipation member 30 is received and supported by the heating section 4 so that the heat dissipation section 32 is positioned above the oil level 8a, but this is not limited to this. The heat dissipation member 30 may be configured such that the heat absorption fins 31a and the heat dissipation section 32 are hollow so that they float in the frying oil 8 and the heat dissipation section 32 is positioned above the oil level 8a, or may be configured such that the heat dissipation section 32 is positioned above the oil level 8a by being suspended from the first oil tank lid 10.
[0050] The heat absorption fin section 31 absorbs heat from the frying oil 8 using the heat absorption fins 31a, and the heat absorbed by the heat absorption fin section 31 is transferred to the heat dissipation section 32. The cooling air from the cooling fan 11 hits the heat dissipation section 32 to cool the heat dissipation section 32, which then dissipates the heat transferred from the heat absorption fin section 31. In this way, the heat dissipation member 30 cools the frying oil 8, and the cooling of the frying oil 8 is promoted by the heat dissipation member 30.
[0051] [Another embodiment] (1) Fig. 9 is a side view of a cleaning device 35 of another embodiment. Similar to the cleaning device 20 shown in Fig. 5, the cleaning device 35 of this embodiment is equipped with five cleaning pipes 21 and a cleaning liquid supply pipe 23.

The cleaning device 35 is supported by a support portion 33a provided on the second oil tank lid 33. The second oil tank lid 33 is not equipped with a cooling fan, an exhaust port, or the like.
[0052] (2) The cleaning nozzle 22 may be provided in the cleaning pipe 21 in a state in which the direction thereof can be manually adjusted. The cleaning nozzle 22 may also be detachable.
[0053] (3) The cleaning nozzle 22 may be provided in the cleaning pipe 21 in a state in which it can be rotated, for example, by the liquid pressure of the cleaning liquid supplied to the cleaning pipe 21.
[0054] (4) In the above-described embodiment, the cleaning device 20, 35 is attached to the fryer body 1 by the first oil tank lid 10 or the second oil tank lid 33, but this is not limited thereto, and the cleaning device may be attached to the fryer body 1 independently without being supported by the oil tank lid.
[0055] (5) In the above embodiment, the fan cover 13 is provided, but the fan cover 13 may not be provided.
[0056] (6) In the above embodiment, the exhaust port cover 14 is provided, but the exhaust port cover 14 may not be provided.
[0057] (7) In the above embodiment, the heat dissipation member 30 is provided, but the heat dissipation member 30 may not be provided.
