Description

Technical Field

[0001] This application relates to the technical field of kitchen appliances, and particularly to a fryer. Background Art

[0002] Current air fryers have become popular in the market and have become a must-have product in every household, just like rice cookers. Through the working principle of hot air convection, air fryers can be used to air-fry various foods such as meats and fries. However, most existing air fryers have a single function and a single cooking method. There is still a relatively large difference in the taste of food cooked by pure air frying and that of deep-fried food. Moreover, for some foods such as breaded foods and chicken nuggets, the cooking method of pure air frying without oil cannot achieve good cooking effects.

[0003] For example, a food processor with a liftable frying basket disclosed in a Chinese utility model patent with the publication number CN210611901U includes a body, a heating device installed in the body, a fan assembly blowing towards the heating device, a fryer located below the heating device, and a frying basket arranged in the fryer. Since there are screw lifting holes at the bottom of the fryer, only a small amount of oil can be placed at the bottom, and even when the frying basket descends to the bottom, the function of completely soaking the food in oil cannot be achieved; there is no separate heating tube at the bottom of the fryer, and because only a small amount of oil can be added, the requirements for deep frying and combined cooking of air frying and deep frying cannot be met. Summary of the Utility Model

[0004] The purpose of the embodiments of this application is to provide a fryer, which includes:

[0005] A main body module, which is respectively provided with a first inner cavity and a second inner cavity surrounding the first inner cavity from the inside to the outside, and a lower heating body for heating up is arranged at the bottom of the first inner cavity;

Through the mechanical transmission system driven by the motor, the automation of the frying basket lifting is realized, improving the convenience and safety of operation.

[0018] As an alternative embodiment, the container module further includes:

[0019] A filter screen, which is arranged between the inner pot and the frying basket and is used to filter the residues falling from the frying basket. The filter screen can prevent food residues from falling into the oil, keep the oil quality clean, and extend the service life of the oil.

[0020] As an alternative embodiment, the main body module includes:

[0021] A body having a cavity with an open top, and a middle bracket is provided on the inner edge of the cavity wall of the cavity.

[0050] This specification may use the phrases "in one embodiment", "in another embodiment", "in yet another embodiment", or "in other embodiments", all of which may refer to one or more of the same or different embodiments according to the present application.

[0051] An embodiment of the present application provides a deep fryer, as Figures 1 - 3 shown. The deep fryer includes a main body module 1, a hot air convection module 2, a container module 3, and a lifting module 4. The lifting module 4 includes a screw 41, a flange nut 42, and a lifting ejector rod 43.

[0052] The main body module 1 is provided with a first inner cavity 11 and a second inner cavity 12 surrounding the first inner cavity 11 from the inside to the outside. A lower heating element 13 for heating up is provided at the bottom of the first inner cavity 11. The hot air convection module 2 is disposed above the main body module 1 and is used to enclose the first inner cavity 11 and heat up the first inner cavity 11.

[0053] The container module 3 is assembled in the first inner cavity 11. The container module 3 includes an inner pot 31 and a frying basket 32. The lifting module 4 is disposed in the main body module 1 and is used to lift the frying basket 32 relative to the inner pot 31 to take out of or enter the inner pot 31.

[0054] Wherein, the screw 41 is vertically arranged and rotatably disposed in the second inner cavity 12. The screw 41 is installed in the second inner cavity 12 through a screw bracket. The flange nut 42 is threadedly connected to the screw 41 and linearly moves up and down along the axial direction of the screw 41 under the rotation of the screw 41.

[0055] One end of the lifting ejector rod 43 extends into the first inner cavity 11 and is connected to the frying basket 32, and the other end extends into the second inner cavity 12 and is connected to the flange nut 42 to lift the frying basket 32 under the drive of the flange nut 42.

[0056] When in use, the user puts the food into the frying basket 32 and places the frying basket 32 in the inner pot 31. Start the deep fryer, and the lower heating element 13 and / or the hot air convection module 2 start to heat up, heating the oil in the inner pot 31, and ensuring uniform distribution of heat through hot air convection. The user operates the lifting module 4 to lift the frying basket 32 in the inner pot 31, which is convenient for putting in and taking out the food, and can also adapt to the cooking mode of the food, such as air frying, deep frying, air frying and deep frying, and air frying after oil immersion.

[0057] As an optional embodiment, as Figure 1 and Figure 7As shown, at least two lifting modules 4 are provided, and the at least two lifting modules 4 are circumferentially arranged around the outer wall of the inner pot 31. With multiple lifting modules 4, the frying basket 32 can be lifted and lowered more smoothly, improving the usage efficiency and stability of the fryer.

[0058] Specifically, when two lifting modules 4 are provided, the two lifting modules 4 are arranged around the outer periphery of the inner pot 31 and are diagonally distributed along the radial center line of the inner pot 31. When three lifting modules 4 are provided, the three lifting modules 4 are arranged around the outer periphery of the inner pot 31 and are triangularly distributed with the axis of the inner pot 31 as the center. When four lifting modules 4 are provided, the four lifting modules 4 are arranged around the outer periphery of the inner pot 31, and the four lifting modules 4 are sequentially connected to form a rectangular structure. These lifting modules 4 are circumferentially arranged around the outer wall of the inner pot 31. Multiple lifting modules 4 work together to make the lifting of the frying basket 32 more stable and uniform.

[0059] As an alternative embodiment, as Figure 1 and Figure 8 shown, the fryer further includes a power module 5 for driving the lifting module 4. The power module 5 includes a motor 51, a double gear 53, at least one screw gear 54, and a belt 55.

[0060] The motor 51 is arranged in the second inner cavity 12, and a motor gear 52 is provided on the output shaft of the motor 51. The double gear 53 is arranged in the second inner cavity 12 and is connected to one of the screws 41. The double gear 53 has a first tooth part and a second tooth part, and the first tooth part meshes with the motor gear 52;

[0061] The at least one screw gear 54 is arranged in the second inner cavity 12 and is arranged around the outer peripheral wall of the inner pot 31 with the double gear 53. The at least one screw gear 54 is respectively connected to the other screws 41, that is, a screw gear 54 is respectively threadedly connected to the other screws 41.

[0062] The belt 55 is sleeved on the second tooth part of the double gear 53 and the screw gear 54 and meshes with the second tooth part of the double gear 53 and the screw gear 54 respectively, so that when the motor gear 52 rotates to drive the double gear 53 to rotate, the at least one screw gear 54 is driven to rotate through the belt 55.

[0063] Among them, when two lifting modules 4 are provided, it includes two screw rods 41 and a screw gear 54. One of the screw rods 41 is connected to one screw gear 54, and the other screw rod 41 is connected to the double gear 53; when three lifting modules 4 are provided, it includes three screw rods 41 and two screw gears 54. Two of the screw rods 41 are respectively connected to the two screw gears 54, and the other screw rod 41 is connected to the double gear 53; when four lifting modules 4 are provided, it includes four screw rods 41 and three screw gears 54. Three of the screw rods 41 are respectively connected to the three screw gears 54, and the other screw rod 41 is connected to the double gear 53.

[0064] After the user starts the motor 51, the motor 51 drives the motor gear 52 to rotate. The motor gear 52 transmits power to the belt 55 through the double gear 53, and the belt 55 transmits the power from the double gear 53 to the screw gear 54, driving the screw rod 41 to rotate. The rotation of the screw rod 41 causes the flange nut 42 to lift linearly along the axis, thereby driving the lifting ejector rod 43 and the frying basket 32 to lift. Through the mechanical transmission system driven by the motor 51, the automation of the lifting of the frying basket 32 is realized, improving the convenience and safety of operation.

[0065] As an optional embodiment, as Figure 1 and Figure 6 shown, the container module 3 further includes a filter screen 33. The filter screen 33 is arranged between the inner pot 31 and the frying basket 32 and is used to filter the residues falling from the frying basket 32. Among them, the filter screen 33 can be hung on the frying basket 32 or in the inner pot 31.

[0066] In the case of using oil, since the frying basket 32 is used inside the filter screen 33 and the food is processed inside the frying basket 32, the food residues will fall into the filter screen 33 instead of in the inner pot 31. After use, only by lifting the filter screen 33 can the oil be filtered, so that the oil in the inner pot 31 after use also becomes clean and can be reserved for the next use, reducing waste.

[0067] As an optional embodiment, as Figures 1 - 3 shown, the main body module 1 includes a main body 14 and a heat insulation cover 17.

[0068] The main body 14 has a cavity 15 with an open top. On the inner edge of the cavity wall of the cavity 15, there is a middle layer bracket 16 that first extends upward along the axial direction of the cavity 15 and then extends inward along the radial direction of the cavity 15. One end of the middle layer bracket 16 that extends inward along the radial direction of the cavity 15 forms an annular shielding portion for the open end of the cavity 15, and the shielding portion is used to seal the second inner cavity 12.

[0069] The heat insulation cover 17 is arranged in the cavity 15 and is connected to one end of the middle layer bracket 16 extending inwards along the radial direction of the cavity 15. The first inner cavity 11 is formed inside the heat insulation cover 17, and the second inner cavity 12 surrounding the first inner cavity 11 is formed between the outer wall of the heat insulation cover 17 and the inner wall of the cavity 15. The design of the heat insulation cover 17 helps with heat preservation and insulation, improves energy efficiency, and ensures the safety of the operator.

[0070] Among them, the lower heating body 13 is fixedly installed on the heat insulation cover 17. During operation, the inner pot 31 is placed on the lower heating body 13. The lower heating body 13 is on the outer side of the bottom of the inner pot 31, and the oil in the inner pot 31 is heated by heat transfer through the inner pot 31. The lower heating body 13 is isolated from the oil and does not come into contact with it.

[0071] In some other embodiments, as Figures 9 - 10 shown, the lower heating body 13 is arranged in a Z-shaped layout, and a fixed connection box is provided at one end away from the inner pot 31. A coupler 6 connected to the power supply is provided on the middle layer bracket 16. When the lower heating body 13 is installed on the inner pot 31, it is connected to the coupler 6 through the fixed connection box to achieve power-on heating operation.

[0072] During use, after placing the inner pot 31 and the filter screen 33, the lower heating body 13 is installed. In this way, the lower heating body 13 is on the inner side of the inner pot 31. When adding oil to the pot, the lower heating body 13 is immersed in the oil and comes into contact with the oil, which can achieve the effect of quickly heating the oil and improve work efficiency.

[0073] As an alternative embodiment, as Figure 1 and Figure 6 shown, the inner diameter of the heat insulation cover 17 decreases from top to bottom along the axial direction of the cavity 15 to form an annular step, and the lifting jack rod 43 passes through the annular step. Among them, the shape of the inner pot 31 matches the shape of the heat insulation cover 17. The design of the annular step can increase the structural stability, facilitate the assembly of the inner pot 31, and provide support for the lifting jack rod 43 at the same time.

[0074] Among them, the inner pot 31 is placed inside the heat insulation cover 17. The inner pot 31 has an avoidance hole for the lifting jack rod 43 to pass through. The lifting jack rod 43 drives the frying basket 32 to move and the inner pot 31 does not lift.

[0075] As an alternative embodiment, as Figure 1 shown, the hot air convection module 2 includes a housing 21, a hot air motor 51, and a fan blade assembly 25. The housing 21 is respectively provided with a third inner cavity 22 and a fourth inner cavity 23 surrounding the third inner cavity 22 from the inside to the outside, and an upper heating body 26 is arranged in the third inner cavity 22.

[0076] The hot air motor 51 is disposed in the fourth inner cavity 23, and the output shaft of the hot air motor 51 extends into the third inner cavity 22. The fan blade assembly 25 is located in the third inner cavity 22 and is connected to the output shaft of the hot air motor 51. The hot air motor 51 is fixed in the third inner cavity 22 by means of screws or snap positions or riveting, etc., and the upper heating element is installed below the hot air blade 251.

[0077] When the user starts the hot air motor 51, the hot air motor 51 drives the fan blade assembly 25 to start rotating, and conveys the gas heated by the upper heating element 26 to the first inner cavity 11 to raise the temperature of the first inner cavity 11. The design of the hot air convection module 2 helps to achieve uniform distribution of heat and improve cooking efficiency.

[0078] As an alternative embodiment, as Figure 1 shown, the fan blade assembly 25 includes a hot air fan blade 251 and a cold air fan blade 252. The third inner cavity 22 is divided into an upper cavity 221 and a lower cavity 222 by a cover body. The output shaft of the hot air motor 51 extends from the upper cavity 221 into the lower cavity 222. The hot air fan blade 251 is located in the lower cavity 222, and the cold air fan blade 252 is located in the upper cavity 221.

[0079] Among them, the output shaft of the hot air motor 51 extends from the upper cavity 221 into the lower cavity 222, driving the hot air fan blade 251 to rotate to generate hot air. The cold air fan blade 252 rotates in the upper cavity 221 to assist in adjusting the temperature or promoting hot air circulation. The cold air is used to dissipate heat from the hot air motor, preventing the heat generated by the upper heating element from diffusing upward to the hot air motor, thereby improving the reliability of use. And this content is a technical means well-known to those skilled in the art, so it will not be elaborated in this application.

[0080] When this application is in use, it has the following cooking modes:

[0081] First, the air fry mode: The hot air convection module 2 and the upper heating element 26 achieve the same air fry function as a traditional air fryer.

[0082] Specifically, turn on the hot air convection module 2, place the inner pot 31 in the first inner cavity 11, then place the frying basket 32 containing food in the inner pot 31. The frying basket 32 is supported on the lifting jack 43, and then cover the hot air convection module 2. Then select the menu for the air fry mode through the function panel.

[0083] In the first step of the program execution, the lifting module 4 automatically operates, and the lifting jack 43 moves upward to lift the frying basket 32 to the highest position, so that there is a space between the frying basket 32 and the bottom of the inner pot 31. In the second step of the program execution, the hot air convection module 2 enters the operating state, the hot air motor 51 rotates to drive the fan assembly to operate, and the upper heating element 26 performs the heating work to achieve the function of air frying.

[0084] Second, deep - fry + air - fry mode: Pour oil into the inner pot 31 according to the specified amount. The lower heating element 13 at the bottom of the main body 14 first heats the oil, then put the food into the frying basket 32, lower the frying basket 32 to the bottommost position for deep - frying. After deep - frying for a certain period of time, raise the frying basket 32 to separate it from the oil, and then perform air - frying.

[0085] Specifically, turn on the hot - air convection module 2, place the inner pot 31 into the first inner cavity 11, then pour the specified amount of cooking oil into the inner pot 31, and then cover the hot - air convection module 2. Finally, select the menu of the deep - fry + air - fry mode through the function panel.

[0086] In the first step of the program execution, the lower heating element 13 at the bottom of the main body 14 starts to heat, raising the temperature of the oil in the inner pot 31. When it reaches a certain temperature, it makes a beeping sound, that is, the temperature is detected by the temperature sensor. When the oil temperature reaches the preset temperature, the user is reminded by the reminder, and the reminder method is not limited to sound.

[0087] At this time, the hot - air convection module 2 needs to be turned on, and then place the frying basket 32 with food into the pot. At this time, the frying basket 32 is at the lowest position, and the food in the frying basket 32 can be completely immersed in the oil. Then cover the hot - air convection module 2 to deep - fry the food. During this process, the lower heating element 13 remains in the working state to keep the temperature of the oil from dropping.

[0088] In the second step of the program execution, after frying for 3 minutes as set by the program, the lifting module 4 runs automatically, and the lifting rod 43 moves upward to lift the frying basket 32 to the highest position, separating the food in the frying basket 32 from the oil. At the same time, the lower heating element 13 on the main body 14 stops heating.

[0089] In the third step of the program execution, while the frying basket 32 is rising, the hot - air convection module 2 enters the operating state. The hot - air motor 51 rotates to drive the fan assembly to operate, and the upper heating element 26 starts to heat to realize the function of air - frying.

[0090] Third, air - fry with automatic oil - immersion mode: Pour oil into the inner pot 31 according to the specified amount. During the air - frying process of the food, the frying basket 32 automatically descends to the bottom, allowing the food to be immersed in the oil and then rises to the highest position to separate from the oil, and then performs air - frying. The frequency of oil - immersion can be preset according to different food menus.

[0091] Specifically, turn on the hot - air convection module 2, place the inner pot 31 into the first inner cavity 11, then pour the specified amount of cooking oil into the inner pot 31, and then place the frying basket 32 with food into the pot. At this time, the frying basket 32 is at the lowest position, and the food in the frying basket 32 can be completely immersed in the oil. Finally, select the menu of the deep - fry + air - fry mode through the function panel.

[0092] In the first step of the program execution, the lifting module 4 runs automatically, and the lifting ejector rod 43 moves upward to lift the frying basket 32 to the highest position, separating the frying basket 32 and the food from the oil. At this time, the food is put in at the beginning for the first oil immersion, so that the surface of the food is covered with oil.

[0093] In the second step of the program execution, while the frying basket 32 is rising, the hot air convection module 2 enters the operating state. The hot air motor 51 rotates to drive the fan assembly to operate, and the upper heating element 26 conducts heating work to realize the function of air frying.

[0094] In the third step of the program execution, after air frying for a certain period of time, the lifting module 4 operates, and the lifting ejector rod 43 moves downward to lower the frying basket 32 to the lowest position, immersing the food in the oil. After staying for 3 seconds, it rises again to separate the food from the oil, and then continues air frying. During the air frying process, the operation of the lifting module 4 enables the frequency of food oil immersion to be set according to different foods.

[0095] Fourth, frying mode: The hot air convection module 2 and the upper heating element 26 do not work. The inner pot 31 is filled with oil according to the specified amount, the lower heating element 13 heats the oil, the frying basket 32 is placed in the inner pot 31, the food is placed in the frying basket 32, and the frying basket 32 is lowered to the lowest position, and the food comes into contact with the oil for frying.

[0096] Specifically, turn on the hot air convection module 2, place the inner pot 31 in the first inner cavity 11, then add the specified amount of cooking oil into the inner pot 31, and then cover the hot air convection module 2. Finally, select the menu of the frying mode through the function panel.

[0097] In the first step of the program execution, the lower heating element 13 at the bottom of the main body 14 conducts heating work to heat up the oil in the inner pot 31, and makes a beeping sound when reaching a certain temperature. At this time, the hot air convection module 2 needs to be turned on, and then the frying basket 32 with food is placed in the pot. At this time, the frying basket 32 is at the lowest position, and the food in the frying basket 32 can be completely immersed in the oil. Then cover the hot air convection module 2 to fry the food. During this process, the lower heating element 13 remains in the working state to keep the temperature of the oil from dropping. In the frying mode state, the hot air convection module 2 does not work, and the lifting module 4 does not work either. Only the lower heating element 13 conducts heating work to realize the frying function.
