Description

Technical Field

[0001] The utility model relates to the field of frying machines, in particular to a frying machine. Background Art

[0002] The applicant submitted a utility model patent on March 30, 2023 (utility model name: a deep fryer, application number: 202320665655.5), which discloses the following scheme: the deep fryer includes a frame, a pot body for holding edible oil fixed to the frame, and a frying basket. A lid that can be raised or lowered by a lifting mechanism is provided directly above the pot body, and a supporting bracket on the bottom of the lid is provided on which the frying basket can be placed in a quick disassembly manner. When the food in the frying basket needs to be fried, the lid moves down with the supporting bracket and the frying basket sinks into the pot body. When using the fryer, it is first necessary to manually place the food to be fried in the hollow frying basket, and then place the frying basket on the supporting bracket. After that, the lifting mechanism drives the lid down until it is covered on the pot body before frying can be carried out. After frying is completed and the lifting mechanism drives the lid up, the frying basket can be manually removed from the supporting bracket. The above scheme has the following shortcomings:

[0003] Since the lid automatically descends and covers the pot body after the frying basket is placed on the supporting bracket, when the frying pan is used, if the food is manually taken in and out, the food may fall out of the frying basket, especially the food after frying (after frying, the food shrinks and becomes smaller in volume, and some meat food that needs to be marinated in advance, such as fried chicken legs and fried chicken wings, needs to be coated with flour during marinating, and the surface is crispy after frying), which is more likely to fall out of the frying basket and fall on the edge of the pot body. As a result, when the lid descends, it first presses on the fallen food and then forcibly covers the pot body. This operation not only causes the lid to fail to completely seal the pot body, reducing the quality of the fried food, but also causes wear on the bottom edge of the lid; in addition, when the frying basket is placed on the supporting bracket and the lid is started to descend, if the operator fails to remove his hand from between the lid and the edge of the pot body in time due to negligence, it is easy to cause pinching. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a frying machine which can prevent a human body from being pinched by a falling pot cover and avoid foreign objects being stuck under the pot cover and causing damage to the pot cover.

DETAILED DESCRIPTION

[0020] like Figure 1 and Figure 2 As shown, the frying machine of the utility model is a device for frying food using edible oil, which comprises a frame, a frying pot 1 installed in the frame, a pot cover 2 installed on a pot mouth 11 of the frying pot 1, and a bracket installed at the bottom of the pot cover 2, wherein the bracket is divided into a left bracket 31 and a right bracket 32 ​​(with a left bracket 31 and a right bracket 32 ​​installed at the left and right sides of the bottom of the pot cover 2) Figure 1 The paper surface where the left and right sides are located is the reference direction, the direction pointing to the lower right is the front, and the direction pointing to the upper left is the rear, and the same applies below. ), the bottom edges of the left bracket 31 and the right bracket 32 ​​are respectively extended inward with a left support plate and a right support plate, and the top left edge and the right edge of the frying basket 3 for holding food are provided with a shelf plate that can be overlapped on the corresponding support plate.

[0021] The frame is provided with a base, and a front plate, a rear plate, a left plate, a right plate and a top plate are installed on the frame. The shape enclosed by the four side plates, the top plate and the base is a rectangular body. The top plate constitutes the table top of the fryer, and the table top is divided into two areas. The front half is a frying area 100, and the back half is an operation area 110. The frying area 100 is an area for the fryer 1 and the cover 2 and other components to cooperate with each other to complete the work of frying food. The operator can put the frying basket 3 containing the ingredients to be fried into the bracket in the operation area 110, or take the frying basket 3 out of the bracket and put it into the operation area 110 after the frying in the fryer 1 is completed.

[0022] The top surface of the operation area 110 is lower than the top surface of the frying area 100. A guide rail 4 is provided in the operation area 110 to facilitate the movement of the frying basket 3 between the frying area 100 and the operation area 110. When the frying basket 3 is loaded into the bracket, the frying basket 3 is first placed on the guide rail 4, and then the frying basket 3 is pushed to move from front to back along the guide rail 4, so that the frying basket 3 can be overlapped on the bracket. When the frying basket 3 needs to be taken out from the bracket, the frying basket 3 can be pulled forward to move the frying basket 3 from the bracket to the guide rail 4 seamlessly.

[0023] The fryer 1 is installed in the frame below the frying area 100. Correspondingly, a rectangular opening is provided on the frying area 100, which is communicated with the fryer 1. The opening is the pot mouth 11 of the fryer 1. The outer contour of the pot cover 2 is a rectangle with the same shape as the pot mouth 11. The pot cover 2 is coaxially arranged with the pot mouth 11 and has a size larger than that of the pot mouth 11. The pot cover 2 is connected to the left and right sides of the bottom of the pot cover 2 by connecting the lifting rods 5 connected to the lifting mechanism (not shown in the figure) on the corresponding side of the frame so that the lifting rods 5 The pot cover 2 can be driven to move up or down in the vertical direction. A guide rod 51 is further provided on the front side of the left and right lifting rods 5 to further ensure that the pot cover 2 moves in a straight line. The lifting mechanism drives the pot cover 2 to move between a position where the sealing cover is closed on the pot mouth 11 (lid closing position) and a set position (lid opening position) located above the pot mouth 11. When the fryer 1 needs to perform frying, the pot cover 2 moves down to the lid closing position. When the frying basket 3 needs to be placed or removed, the pot cover 2 moves up to the lid opening position.

[0024] like Figures 1 to 4As shown, the innovation of the utility model is that a safety device is provided on the pot cover 2, and the safety device is electrically connected to the safety control module of the fryer. The safety control module controls the pot cover 2 to rise or fall by controlling the driving motor connected to the lifting rod 5 in the lifting mechanism. If foreign matter (such as fingers that the operator has not removed in time, food or other debris that has not been cleaned up in time, etc.) is left on the table below the pot cover 2, the pot cover 2 can quickly trigger the limit switch assembly in the safety device after contacting the above foreign matter during the descent process, and the safety control module sends a command to the lifting mechanism to move the lifting rod 5 upward, and the driving motor drives the lifting rod 5 to drive the pot cover 2 to immediately stop moving downward and move upward (it can move up a certain distance or move up to the described lid opening position) to remove the foreign matter from under the pot cover 2. The safety device prevents the problem in the prior art that the pot cover 2 continues to descend even when there is the above foreign matter blocking the pot cover 2 from moving downward, resulting in the operator being pinched or the pot cover 2 and other equipment being damaged, thereby effectively improving the user's operating safety when using the fryer and the intelligence level of the fryer, and extending the service life of the pot cover 2.

[0025] 1. Pot cover 2

[0026] The pot cover 2 is composed of an inner cover 22 and an outer cover 21 .

[0027] 1) Inner cover 22

[0028] The function of the inner cover 22 is that its bottom is fixedly connected to the lifting rod 5, so that the outer cover 21 can be raised or lowered under the drive of the lifting rod 5. When the pot cover 2 is in the closed position, the inner cover 22 is sealed against the periphery of the pot mouth 11.

[0029] The outer contour of the inner cover 22 is a rectangular body, which is coaxially arranged with the pot mouth 11. A rectangular recess is arranged on the top of the inner cover 22, and a rectangular groove is opened in the bottom area of ​​the inner cover 22. A sealing gasket 25 for enhancing the sealing effect between the pot mouth 11 is installed in the groove. The sealing gasket 25 is adapted to be pressed around the pot mouth 11 to form a closed space in the fryer 1. The upper ends of the lifting rod 5 and the guide rod 51 are fixed to the bottom surface of the inner cover 22 and are located beside the sealing gasket 25. The lower end of the lifting rod 5 passes downward through the through hole on the frying area 100 and is connected to the corresponding driving motor. The left bracket 31 and the right bracket 32 ​​are respectively installed on the left and right sides of the rectangular area enclosed by the sealing gasket 25.

[0030] 2) Outer cover 21

[0031] The outer cover 21 is composed of a rectangular and integrally formed top plate, front side plate, rear side plate, left side plate and right side plate. The front, rear, left and right side plates are respectively connected to the four sides of the top plate, and the vertical heights of the front, rear, left and right side plates are the same, thereby enclosing a rectangular body with an open bottom and a cavity.

[0032] The outer cover 21 is buckled onto the inner cover 22 from top to bottom and connected to the inner cover 22 via the elastic structure in the safety device, so that the outer cover 21 and the inner cover 22 can move relative to each other in the vertical direction.

[0033] When the outer cover 21 and the inner cover 22 do not move relative to each other, the top plate of the outer cover 21 contacts the top surface of the inner cover 22 and the horizontal plane where the bottom edge of the outer cover 21 is located is located below the bottom surface of the inner cover 22. The front, rear, left and right side plates of the outer cover 21 are opposite to the corresponding side walls of the inner cover 22 and a certain space (hereinafter referred to as the gap) is left between them. The gap between the left side plate and the left side wall of the inner cover 22 (referred to as the left gap) and the gap between the right side plate and the right side wall of the inner cover 22 (referred to as the right gap) are respectively used to install the limit switch assembly.

[0034] If the above-mentioned foreign matter exists on the table surface below the outer cover 21, since the bottom edge of the outer cover 21 is lower than the bottom surface of the inner cover 22, when the outer cover 21 moves downward with the inner cover 22, the foreign matter first abuts against the bottom edge of the outer cover 21 and generates an upward reaction force on the outer cover 21, so that the outer cover 21 moves upward. At this time, as the lifting rod 5 continues to apply a pulling force to the inner cover 22, the inner cover 22 continues to move downward. As a result, the outer cover 21 and the inner cover 22 move relative to each other. When the relative movement of the two reaches a set distance (this distance is called the trigger distance), the limit switch assembly is triggered, so that the inner cover 22 immediately stops moving downward and moves upward. Preferably, the trigger distance is as small as possible to reduce the time from when the outer cover 21 contacts the foreign object to when the limit switch 23 is triggered, so as to reduce the risk of the operator being pinched and the pot cover 2 being damaged as much as possible. The trigger distance is preferably less than or equal to the height difference between the bottom edge of the outer cover 21 and the bottom surface of the inner cover 22. The trigger distance set in the utility model is preferably in the range of 8 mm to 15 mm.

[0035] The edge of the pot mouth 11 of the fryer 1 extends upward to the top surface of the frying area 100 or a convex edge is provided on the edge, so that when the inner cover 22 moves down and contacts the convex edge, a gap is left between the bottom edge of the outer cover 21 and the surface of the frying area 100. This arrangement avoids the situation that when the pot cover 2 needs to be moved down to the cover-closed position without foreign matter, the outer cover 21 has already collided with the table surface where the frying area 100 is located, causing the table surface to generate an upward rebound force on the outer cover 21, causing the outer cover 21 to move up and trigger the limit switch assembly, thereby causing the inner cover 22 to move up again with the outer cover 21, resulting in the inner cover 22 being unable to cover the pot mouth 11, and the frying work cannot be carried out.

[0036] 2. Safety device

[0037] The safety device is composed of the limit switch assembly and the elastic structure.

[0038] 1) Limit switch assembly

[0039] There is at least one group, and the utility model is preferably four groups that are symmetrically distributed, wherein two groups are installed in the left gap with a front-to-back interval, and the other two groups are installed in the right gap.

[0040] Take one of the groups of the left gap as an example: the limit switch assembly is composed of a limit switch 23 and a touch plate 24, the limit switch 23 is fixedly installed on the left outer wall of the inner cover 22 through a mounting plate and the contact of the limit switch 23 faces downward; the cross-sectional shape of the touch plate 24 is "L"-shaped, which is divided into a horizontal plate and a vertical plate, the vertical plate is fixedly installed on the inner surface of the left side plate of the outer cover 21, the horizontal plate extends inwardly and is located below the contact of the limit switch 23 and directly opposite to the contact, and the trigger distance is left between the horizontal plate and the contact. In the utility model, when the outer cover 21 contacts a foreign object during the downward movement, the outer cover 21 immediately moves up with the touch plate 24 relative to the inner cover 22 under the action of the reaction force, so that the upper surface of the horizontal plate can contact the corresponding limit switch 23 to trigger the limit switch 23.

[0041] 2) Elastic structure

[0042] The elastic structure is arranged in the vertical direction of the inner cover 22 and the outer cover 21, and is used to connect the inner cover 22 and the outer cover 21 together so that the two can move relative to each other in the vertical direction without being separated from each other. There is at least one group of elastic structures, and the utility model preferably has four groups, which are symmetrically arranged on the four corners of the upper and lower relative areas of the outer cover 21 and the inner cover 22.

[0043] Each set of elastic structures includes a positioning cylinder 6 , an adjusting screw 7 and a spring 8 .

[0044] Take one of the groups as an example:

[0045] The positioning tube 6 is cylindrical, and its upper end and lower end are connected to form an axial cylindrical channel, and the openings at the upper end and the lower end of the channel are respectively called the upper hole and the lower hole.

[0046] The positioning tube 6 is fixedly connected to the outer cover 21. To facilitate installation, the outer peripheral wall of the upper end of the positioning tube 6 is provided with a circular skirt integrally formed therewith, and the skirt is provided with a plurality of mounting holes. The top end surface of the skirt is abutted against and locked with the bottom surface of the top plate of the outer cover 21, and a through hole with the same diameter as the upper hole is provided on the top plate opposite to the upper hole. The lower end of the positioning tube 6 extends downward and is inserted into the recess of the inner cover, and the lower end surface of the positioning tube 6 abuts against the top surface of the recess (when the inner cover 22 and the outer cover 21 do not move relative to each other).

[0047] The adjusting screw 7 is coaxial with the hole, is disposed in the hole and fixedly connected to the inner cover 22, and the adjusting screw 7 and the hole can move relative to each other in the vertical direction.

[0048] In order to realize the installation of the adjusting screw 7, the diameter of the nut of the adjusting screw 7 is smaller than the aperture of the upper hole, the lower end of the rod of the adjusting screw 7 is a stepped shaft with an external thread, the radius of the stepped shaft is smaller than the radius of other parts of the rod, and the aperture of the lower hole is larger than the diameter of the rod and smaller than the diameter of the nut, so as to prevent the nut from penetrating from the lower hole when the inner cover 22 and the outer cover 21 move relative to each other, causing the inner cover 22 and the outer cover 21 to be disconnected; when installing the adjusting screw 7, first put the spring 8 on the On the rod of the adjusting screw 7, the lower end of the rod is passed downward into the channel through the through hole and the upper hole in turn, so that the nut and the spring 8 are placed in the channel and a gap is left between the spring 8 and the hole wall of the channel, and the step shaft passes through the lower hole and is screwed and fixed with the screw hole on the inner cover 22, the step surface of the step shaft contacts the top surface of the recessed position of the inner cover 22, the upper end of the spring 8 abuts against the bottom surface of the nut, and the lower end thereof abuts against the periphery of the small hole, thereby realizing the movable connection between the inner cover 22 and the outer cover 21.

[0049] When the outer cover 21 hits a foreign object, the outer cover 21 moves upward relative to the inner cover 22, so that the touch plate 24 triggers the limit switch 23. At the same time, the positioning cylinder 6 moving upward compresses the spring 8. After the limit switch 23 is triggered, the lifting rod 5 pushes the inner cover 22 to move upward. At the same time, the outer cover 21 is reset to the top plate of the outer cover 21 and the top surface of the inner cover 22 again under the action of the rebound force of the spring 8 and the action of gravity, and the limit switch 23 is also out of contact with the touch plate 24.
