Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of frying equipment, specifically to a novel frying oven. Background Technology
[0002] A deep fryer is a kitchen appliance used for cooking food. It heats oil to a certain temperature using heating elements, and then places the food into the frying tank to fry. It uses hot oil to fry various foods, such as French fries, chicken cutlets, and fried dough sticks.
[0003] Existing electromagnetic fryers typically have a coil at the bottom of the oil tank for heating. The bottom of the oil tank is heated as a whole by the coil, with no cold zone. This means that the coil heats the entire bottom of the tank during operation, causing the residue that has settled at the bottom to be repeatedly heated and burnt, which affects the frying effect and the shelf life of the oil.
[0004] Therefore, further improvements are needed. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a new type of fryer in which food residue in the low-temperature layer will not be repeatedly fried and heated or even burned, thus avoiding affecting the effect of frying food.

[0009] As a specific embodiment, the heating device includes an external heating tube and an electromagnetic generator capable of heating the external heating tube through electromagnetic induction. The electromagnetic generator is disposed inside the external heating tube and is concentrically arranged with the external heating tube.
[0010] As a specific embodiment, a heat insulation layer is provided between the external heating tube and the electromagnetic generator. The heat insulation layer is made of insulating material and is fixedly connected to the inner side of the external heating tube.
[0011] As a specific embodiment, the two ends of the external heating tube extend outward through the side wall of the oil cylinder, and a connecting flange is provided on the outer side wall of the oil cylinder, which is in close cooperation with the external heating tube.

The inner inclined surface is inclined from top to bottom toward the middle of the cooking cavity, and the width of the left and right sides of the low-temperature layer decreases from top to bottom.
[0013] As a specific embodiment, a partition is provided inside the cooking cavity at the position corresponding to the upper side of the heating device, and several slag leakage holes are distributed on the partition.
[0014] As a specific embodiment, the outer side of the cylinder is provided with a shell body, and the rear side of the shell body is connected to a rear baffle that can be detached from it. An electrical cavity is formed between the rear baffle and the shell body, and an electrical control device is provided in the electrical cavity. An isolation plate is provided in the shell body at the position between the electrical cavity and the cylinder.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] See Figures 1-4This novel deep fryer includes an oil cylinder 1, which has a cooking chamber 11. A heating device 2 is installed in the cooking chamber 11, and there is a gap between the heating device 2 and the bottom of the cooking chamber 11. A low-temperature layer 111 is formed in the cooking chamber 11 corresponding to the position below the heating device 2. Since the low-temperature layer 111 is located below the heating device 2, the heat generated by the heating device 2 is relatively difficult to transfer to the oil in the low-temperature layer 111. Therefore, the oil temperature in the low-temperature layer 111 is relatively low, so the food residue in the low-temperature layer 111 will not be repeatedly fried and heated or even burned, thus avoiding affecting the effect of frying food.
[0025] Furthermore, several sets of heating devices 2 are distributed in the cooking cavity 11 along the left and right directions, which can improve the efficiency of frying food.
[0026] Furthermore, the heating device 2 includes an external heating tube 21 and an electromagnetic generator 22 that can heat the external heating tube 21 through electromagnetic induction. The electromagnetic generator 22 is disposed inside the external heating tube 21 and is concentrically disposed with the external heating tube 21. The electromagnetic generator does not need to directly contact the oil in the oil cylinder 1, making the product safer and more hygienic.
[0027] The electromagnetic generator 22 is preferably a copper sheet that can conduct electricity and is arranged around the center of the heating device 2. Compared with enameled wire, the copper sheet has better heat dissipation effect, and the electromagnetic generator 22 is less likely to burn out.
[0028] Furthermore, a heat insulation layer 23 is provided between the external heating tube 21 and the electromagnetic generator 22. The heat insulation layer 23 is made of insulating material and is connected and fixed to the inner side of the external heating tube 21, which further provides heat insulation for the electromagnetic generator 22 and extends the service life of the electromagnetic generator 22.
[0029] Furthermore, the two ends of the external heating tube 21 extend outward through the side wall of the oil cylinder 1. A connecting flange 12 is provided on the outer side wall of the oil cylinder 1. The connecting flange 12 fits tightly with the external heating tube 21, improving the connection strength between the external heating tube 21 and the oil cylinder 1, and making the sealing at the connection point better.
[0030] Furthermore, the oil cylinder 1 is provided with an inner inclined surface 13 on the left and / or right side of the low temperature layer 111. The inner inclined surface 13 is inclined from top to bottom toward the middle of the cooking cavity 11. The width of the left and right sides of the low temperature layer 111 decreases from top to bottom. The volume of the low temperature layer 111 is relatively small, and correspondingly, the amount of oil in the low temperature layer 111 is relatively small, ensuring that there is a relatively sufficient amount of oil in the oil cylinder 1 for frying food.
[0031] Furthermore, a partition 3 is provided in the cooking cavity 11 at the position corresponding to the upper side of the heating device 2. Several leakage holes 31 are distributed on the partition 3. The partition 3 can reduce the chance of food coming into direct contact with the heating device 2. At the same time, food residue can fall down to the low temperature layer 111 through the leakage holes 31.
[0032] Furthermore, the outer side of the cylinder 1 is provided with a housing body 4, and the rear side of the housing body 4 is connected to a rear baffle 5 that can be detached from it. An electrical cavity is formed between the rear baffle 5 and the housing body 4, and an electrical control device 6 is provided in the electrical cavity, which facilitates the user to quickly inspect and repair the electrical control device 6.
[0033] An isolation plate 41 is provided inside the main body 4 at the position between the electrical cavity and the oil cylinder 1. A heat dissipation hole 51 is provided on the rear baffle 5. A cooling fan 7 is installed and connected inside the electrical cavity at the position corresponding to the heat dissipation hole 51, which can cool down the electronic control device 6. The isolation plate 41 can reduce the impact of the heat of the oil cylinder 1 on the electrical cavity. At the same time, the cooling fan 7 can improve the heat dissipation effect of the electrical cavity and extend the service life of the electronic control device 6.
[0034] Furthermore, a display and control component 8 for displaying information and / or controlling operation is provided on the front side of the shell body 4. The display and control component 8 is electrically connected to the electronic control device 6, allowing the user to control the device from the front side.
[0035] Furthermore, a wire groove 9 is provided inside the shell body 4 at the position between the display and control component 8 and the electric control device 6. The wire groove 9 is U-shaped with an opening on the side facing away from the oil cylinder 1, which can make the wire arrangement between the display and control component 8 and the electric control device 6 more neat and reasonable, the installation of the wire is relatively simple, and the heat of the oil cylinder 1 can have a relatively low impact on the wire.
[0036] The above embodiments are merely preferred embodiments of this utility model, and other implementations are also possible. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model, and all such equivalent modifications or substitutions are included within the scope set forth in the claims of this application.
