Abstract
Description
Technical Field
[0001] This utility model relates to the field of filtration technology, and in particular to a heating and filtration device for a fryer. Background Technology
[0002] In the food processing industry, deep fryers are widely used in the production of fried chicken and other fried foods. During the frying process, crumbs from the surface of the fried chicken inevitably fall into the oil tank. Currently, the industry commonly uses a slotted spoon to scoop the crumbs out of the oil tank for cleaning. This method is simple to operate, low in cost, and can quickly remove most of the larger crumbs.
[0003] However, this traditional cleaning method has significant drawbacks. Because the mesh of the strainer cannot be perfectly fine, a large amount of fine debris still seeps to the bottom of the oil tank during the scooping process. As frying continues, these fine debris accumulate. Under the influence of high-temperature oil, they accelerate the oxidation and rancidity of the frying oil, causing a decline in its quality, affecting the flavor and texture of fried foods, shortening the oil's shelf life, and increasing production costs.
[0004] Therefore, there is an urgent need to design a more effective method for cleaning debris to solve the aforementioned problems in the existing technology. Utility Model Content
[0005] The technical problem this invention aims to solve is to provide a heating and filtering device for fryers. This addresses the issue that most existing fryers have U-shaped heating tubes installed at the bottom of the oil tank for heating the oil. These U-shaped heating tubes result in a narrow and complex structure at the bottom of the oil tank. When cleaning debris, operators find it difficult to directly scoop it out. Traditional cleaning methods are not only time-consuming and labor-intensive but also ineffective, leaving debris residue in the oil tank. Prolonged soaking of this residue in high-temperature oil causes rapid oxidation and deterioration of the frying oil, affecting the taste and quality of fried foods. It also increases the frequency of oil changes, raising production costs.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0007] A heating and filtering device for a deep fryer includes an oil tank. A control unit is connected to the upper right end of the oil tank. Installation mechanisms are provided at the front and rear ends of the control unit. A filtering mechanism is provided inside the oil tank. The filtering mechanism includes a push plate connected to the bottom of the oil tank. A first L-shaped plate is fixedly connected to the upper rear end of the push plate. A second L-shaped plate is connected to the left end of the oil tank. A bottom frame is fixedly connected to the lower side of the second L-shaped plate. A metal filter screen is fixedly connected to the bottom inner side of the bottom frame.
[0008] Optionally, the mounting mechanism includes a mounting plate fixedly connected to the lower ends of the front and rear sides of the control body, bolts connecting the left and right ends inside the mounting plate, a U-shaped frame connecting the outer end of the mounting plate, and a sealing plate fixedly connected to the inner side of the end of the U-shaped frame away from the control body.
[0009] Optionally, a connecting pipe is fixedly connected to the left end of the control unit, and a U-shaped heating tube is installed at the other end of the connecting pipe. A conductive wire is installed at the left end of the control unit, and the conductive wire passes through the inside of the connecting pipe and is connected to the U-shaped heating tube at the other end. A cable is installed at the right end of the control unit, and a plug is installed at the other end of the cable. A stainless steel frying basket is placed at the top of the oil tank.
[0010] Optionally, the push plate is located below the U-shaped heating tube, the lower side of the push plate is slidably connected to the inner bottom of the oil tank, and the front and rear sides of the push plate are slidably connected to the front and rear ends of the inner side of the oil tank.
[0011] Optionally, the inner rear end of the oil tank body is slidably connected to the upper rear end of the oil tank body and the inner side of the first L-shaped plate.
[0012] Optionally, a groove is provided at the bottom left side of the inner side of the oil tank body, the outer side of the bottom frame is slidably connected to the inner side of the groove, the bottom side of the metal filter screen abuts against the bottom end of the inner side of the groove, and the height of the bottom frame is the same as the height of the groove.
[0013] Optionally, a slot is provided at the middle position of the upper left end of the oil tank body, the left side of the vertical part of the second L-shaped plate is slidably connected to the inner left end of the oil tank body, and the outer right end of the horizontal part of the second L-shaped plate is slidably connected to the inner side of the slot.
[0014] Optionally, mounting holes are provided at both the left and right ends inside the mounting plate, a threaded groove is provided on the upper right side of the oil tank body, the outer side of the bolt is slidably connected to the inner side of the mounting hole, the outer side of the bolt is threadedly connected to the inner side of the threaded groove, the lower side of the bolt head abuts against the upper side of the mounting plate, and the lower side of the control body abuts against the upper right end of the oil tank body.
[0015] Optionally, the left and right ends of the inner side of the U-shaped frame are slidably connected to the left and right sides of the mounting plate, the upper side of the bolt is slidably connected to the upper end of the inner side of the U-shaped frame, and the side of the U-shaped frame away from the sealing plate abuts against the outer side of the control body. The sealing plate is a magnetic plate, and the mounting plate is an iron plate.
[0016] Optionally, rubber pads are attached to the side of the U-shaped frame away from the sealing plate and to the bottom side.
[0017] Compared with the prior art, this utility model has at least the following beneficial effects:
[0018] In the above solution, by setting up a filtration mechanism, after frying for a period of time inside the oil tank, the first L-shaped plate slides to the left, driving the pusher plate to slide to the left along the inner bottom of the oil tank, sliding all the debris that has fallen to the inner bottom of the oil tank to the left. After the first L-shaped plate slides to the inner left end of the oil tank, the pusher plate pushes the debris to the left end of the oil tank, so that the debris falls into the bottom frame and metal filter screen at the inner left end of the oil tank. Then, the second L-shaped plate is pulled up, driving the bottom frame and metal filter screen at the lower end to move up. At the same time as moving up, the oil in the oil tank is filtered out through the metal filter screen. After the bottom frame and metal filter screen are pulled out of the oil tank, debris of different particle sizes in the oil tank can be filtered out and removed together. This makes the cleaning of debris in the oil tank very comprehensive and convenient, and the cleaning operation can be carried out during the frying process, so that the debris in the oil tank can be cleaned up quickly at any time.
[0019] By setting up an installation mechanism, after the control unit and the mounting plate are installed and fixed to the upper right end of the oil tank, the U-shaped frame is slid to the outer end of the mounting plate until the sealing plate contacts the mounting plate. This allows the mounting plate to adhere to the outer side of the mounting plate, while the side of the U-shaped frame away from the sealing plate contacts the outer side of the oil tank, sealing the mounting plate between the control unit, the U-shaped frame, and the sealing plate. This prevents oil from splashing onto the bolt head surface during frying, and thus prevents the bolt head from becoming too lubricated due to oil stains, making it difficult to turn and disassemble the bolt when the control unit needs maintenance.

[0034] like Figures 1 to 3 As shown, an embodiment of this utility model provides a heating and filtering device for a fryer, including an oil tank 1. A control unit 2 is connected to the upper right end of the oil tank 1. A connecting pipe 9 is fixedly connected to the left end of the control unit 2. A U-shaped heating tube 3 is installed at the other end of the connecting pipe 9. A conductive wire is installed at the left end of the control unit 2, and the conductive wire passes through the interior of the connecting pipe 9 and connects to the U-shaped heating tube 3 at the other end. A cable 4 is installed at the right end of the control unit 2, and a plug 5 is installed at the other end of the cable 4. A stainless steel frying basket 8 is placed at the upper end of the oil tank 1. Thus, after the plug 5 is plugged into the socket, the control unit 2 can heat the oil in the oil tank 1 by energizing the U-shaped heating tube 3 through the conductive wire.
[0035] The control body 2 is provided with mounting mechanisms at both ends. The mounting mechanisms include mounting plates 601 fixedly connected to the lower ends of the front and rear sides of the control body 2. Bolts 602 are connected to the left and right ends inside the mounting plates 601. Mounting holes are opened at the left and right ends inside the mounting plates 601. A threaded groove is opened on the upper right side of the oil tank body 1. The outer side of the bolts 602 is slidably connected to the inner side of the mounting holes. The outer side of the bolts 602 is threadedly connected to the inner side of the threaded groove. The lower side of the bolt head part abuts against the upper side of the mounting plate 601. The lower side of the control body 2 abuts against the upper right end of the oil tank body 1. After placing the control unit 2 on the upper right side of the oil tank 1, the bolt 602 is passed through the mounting hole inside the mounting plate 601 and then threaded into the threaded groove until the threaded head of the bolt 602 moves to the upper side of the mounting plate 601, so that the mounting plate 601 is fixed to the upper right side of the oil tank 1, thereby fixing the control unit 2 to the upper right side of the oil tank 1, completing the installation of the control unit 2 on the oil tank 1.
[0036] The mounting plate 601 has a U-shaped frame 603 connected to its outer end. A sealing plate 604 is fixedly connected to the inner side of the end of the U-shaped frame 603 away from the control body 2. The left and right ends of the inner side of the U-shaped frame 603 are slidably connected to the left and right sides of the mounting plate 601. The upper side of the bolt 602 is slidably connected to the upper inner side of the U-shaped frame 603. The side of the U-shaped frame 603 away from the sealing plate 604 abuts against the outer side of the control body 2. The sealing plate 604 is a magnetic plate, and the mounting plate 601 is an iron plate. After the control body 2 and mounting plate 601 are installed and fixed to the upper right end of the oil tank body 1, the U-shaped frame 603 is slid to the outer end of the mounting plate 601 until the sealing plate 604 contacts the mounting plate 601. This allows the mounting plate 601 to adhere to the outer side of the mounting plate 601, while the side of the U-shaped frame 603 away from the sealing plate 604 contacts the outer side of the oil tank body 1, sealing the mounting plate 601 between the control body 2, the U-shaped frame 603, and the sealing plate 604. This prevents oil from splashing onto the screw head surface of the bolt 602 during frying, and thus prevents the screw head of the bolt 602 from becoming too lubricated due to oil stains, making it difficult to turn and disassemble the bolt 602 when the control body 2 needs maintenance.
[0037] In addition, rubber pads are affixed to the side and bottom of the U-shaped frame 603 away from the sealing plate 604. Thus, after the U-shaped frame 603 is connected to the outer end of the mounting plate 601, the rubber pads on the outer side of the U-shaped frame 603 will contact the front and rear sides of the control body 2 and the upper right end of the oil tank 1, ensuring a seal at the contact points between the U-shaped frame 603 and the control body 2 and the oil tank 1, preventing oil stains from flowing into the U-shaped frame 603.
[0038] like Figure 4 and Figure 5 As shown, the oil tank 1 is equipped with a filtration mechanism, which includes a push plate 701 connected to the bottom of the oil tank 1. The push plate 701 is located below the U-shaped heating tube 3. The lower side of the push plate 701 is slidably connected to the bottom inner side of the oil tank 1, and the front and rear sides of the push plate 701 are slidably connected to the front and rear ends of the inner side of the oil tank 1. The rear end of the inner side of the oil tank 1 is slidably connected to the rear end of the upper side of the oil tank 1 and the inner side of the first L-shaped plate 702. Thus, when the first L-shaped plate 702 is slid to the left along the rear end of the oil tank 1, the push plate 701 can be driven to slide along the bottom inner side of the oil tank 1, thereby scraping the debris that has settled to the bottom of the oil tank 1 to the left.
[0039] In addition, a first L-shaped plate 702 is fixedly connected to the upper rear end of the push plate 701, a second L-shaped plate 703 is connected to the inner left end of the oil tank body 1, a bottom frame 704 is fixedly connected to the lower side of the second L-shaped plate 703, and a metal filter 705 is fixedly connected to the inner bottom end of the bottom frame 704. A groove is provided at the left side of the inner bottom end of the oil tank body 1, the outer side of the bottom frame 704 is slidably connected to the inner side of the groove, the bottom side of the metal filter 705 abuts against the inner bottom end of the groove, and the height of the bottom frame 704 is the same as the height of the groove. A slot is provided at the middle position of the upper left end of the oil tank body 1, the left side of the vertical part of the second L-shaped plate 703 is slidably connected to the inner left end of the oil tank body 1, and the outer side of the right end of the horizontal part of the second L-shaped plate 703 is slidably connected to the inner side of the slot. After frying for a period of time inside the oil tank 1, the first L-shaped plate 702 slides to the left, causing the pusher plate 701 to slide to the left along the inner bottom edge of the oil tank 1. This slides the debris that has fallen to the inner bottom edge of the oil tank 1 to the left until the first L-shaped plate 702 slides to the inner left edge of the oil tank 1. Then, the pusher plate 701 pushes the debris to the left edge of the inner left edge of the oil tank 1, causing the debris to fall into the bottom frame 704 and metal filter screen 705 on the inner left edge of the oil tank 1. Then, the second L-shaped plate 703 is pulled up, bringing... The bottom frame 704 and metal filter 705 at the lower end move upward, and at the same time, the oil in the oil tank 1 is filtered out through the metal filter 705. After the bottom frame 704 and metal filter 705 are pulled out of the oil tank 1, the debris of different particle sizes in the oil tank 1 can be filtered out and removed together. This makes the cleaning of debris in the oil tank 1 very thorough and convenient, and the cleaning operation can be carried out during the frying process, so that the debris in the oil tank 1 can be cleaned up quickly at any time.
[0040] The working principle of the technical solution provided by this utility model is as follows: When it is necessary to clean the debris in the oil tank 1, the first L-shaped plate 702 slides to the left, driving the push plate 701 to slide to the left along the inner bottom of the oil tank 1, and the debris that has fallen to the inner bottom of the oil tank 1 slides to the left until the first L-shaped plate 702 slides to the inner left end of the oil tank 1. Then, the push plate 701 pushes the debris to the left to the inner left end of the oil tank 1, so that the debris falls into the bottom frame 704 and metal filter screen 705 at the inner left end of the oil tank 1. Then, the second L-shaped plate 703 is pulled up, driving the bottom frame 704 and metal filter screen 705 at the lower end to move up. At the same time as moving up, the oil in the oil tank 1 is filtered out through the metal filter screen 705 until the bottom frame 704 and metal filter screen 705 are pulled out of the oil tank 1. Then, the debris in the second L-shaped plate 703 and bottom frame 704 is poured out and cleaned.
[0041] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
