Description

Technical Field

[0001] The present invention relates to the technical field of kitchen equipment, and in particular to an air fryer capable of cooking different ingredients at the same time; the present invention also relates to a control method for the aforementioned air fryer. Background Art

[0002] An air fryer is a new type of household appliance that uses high-speed, high-temperature air circulation technology to fry food. The air fryer includes a body, a cooking cavity is formed in the body, a hot air component is provided in the body that can send high-temperature air into the cooking cavity, and a pot body for holding food that can enter and exit is provided in the cooking cavity. The hot air generated by the hot air component when it is working is used to heat the food in the pot body. The hot air is fully in contact with the food, and the surface of the food is used to quickly lose moisture instantly, or the fat produced by the food itself is added to make the surface of the food form a crispy taste, showing the effect of being fried. Most of the existing air fryers are single-pot structures, which makes the air fryer have a small capacity for cooking food and cannot cook a variety of different ingredients at the same time. Therefore, when a user wants to use the existing air fryers on the market to cook a large amount of food at one time or cook two different ingredients, they need to be cooked separately in batches, and the food cooked first may also become cold after being taken out due to the long waiting time for the food cooked later, which greatly affects the convenience of users in daily use of air fryers.

[0003] For this reason, double-bottle air fryers have also appeared on the market, such as the utility model patent "A double-bottle convection air fryer" with patent number CN202221533535.1 (publication number CN217610638U), and the utility model patent "A double-layer steam air fryer" with patent number CN202221415699.4 (publication number CN217959766U), both of which disclose such a two-bottle air fryer structure, one of which is two pots arranged side by side, and the other is two pots arranged at intervals up and down. Compared with a single-bottle air fryer, it can cook more food at a time, and the food in different pots can be cooked in different ways, so that not only can more food be cooked at a time, but also food with multiple flavors can be made at the same time, enriching the taste of food cooking.

[0004] However, no matter it is a single-pot air fryer or a double-pot air fryer, the pot body plays the role of closing the front opening of the body, and the pot body is an indispensable component. The addition of the pot body invisibly increases the cost; because the space of each pot body is limited, that is, the cooking space is certain, when it is necessary to cook larger foods, the existing air fryers are not suitable.

[0005] To sum up, both the single-pot air fryer and the double-pot air fryer can be further improved. Summary of the invention

[0006] The first technical problem to be solved by the present invention is to provide an air fryer with a simple structure, low cost, and the ability to reasonably partition the internal space of the pot body and cook different ingredients at the same time, in view of the current status of the existing technology.

[0007] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: an air fryer that can cook different ingredients at the same time, including a body, a large cooking cavity with an opening facing forward is formed inside, and the body is provided with an air inlet and an exhaust port; a hot air component is arranged in the body and located above the large cooking cavity, and the hot air component can send high-temperature gas into the large cooking cavity; it is characterized in that: the left and right inner walls of the large cooking cavity are provided with first convex ribs, and the first convex ribs opposite to the left and right are used for a large baking tray to be placed; the front end of the body is hinged to a door body for opening and closing the large cooking cavity, and a detachable partition is installed in the middle of the large cooking cavity, and the left and right side walls of the partition are provided with second convex ribs, and the partition installed in the large cooking cavity isolates the large cooking cavity into two small cooking cavities that are independent of each other and spaced apart from each other on the left and right, and the first convex rib and the second convex rib opposite to the left and right in each small cooking cavity are used for a small baking tray to be placed.

[0008] As a preferred solution, there are two hot air components and they work independently of each other, each hot air component corresponds to a small cooking cavity, and there are two groups of exhaust ports, each exhaust port corresponds to one of the small cooking cavities. In this solution, when the partition is not assembled, the two hot air components can work simultaneously, or the two hot air components can work alternately; and when the partition is assembled, only one of the hot air components can work to heat the corresponding small cooking cavity, and of course, both hot air components can work to heat the corresponding small cooking cavities respectively, and the working modes of the two hot air components can also be different according to the actual small cooking cavities.

[0009] Of course, there may be only one set of hot air components. When the partition is not assembled, the hot air components heat the large cooking cavity. When the partition is assembled, the hot air components heat the two small cooking cavities at the same time.

[0010] In order to conveniently and securely assemble the partition into the large cooking cavity, a slide groove is provided in the front-to-back direction at the bottom of the large cooking cavity, and a dowel is provided at the bottom of the partition to be plugged into the slide groove; in order to make the control system design more humane, a first trigger switch is provided at the inner top of the large cooking cavity to detect whether the partition is assembled into the large cooking cavity. When the partition is assembled into the large cooking cavity, the first trigger switch is triggered by the top of the partition. According to whether the first trigger switch is triggered by the partition, a signal can be given to the control panel, and the control panel can know whether it is a whole-cavity working mode or a double-cavity working mode, which is conducive to precise control.

[0011] To facilitate independent control of the small cooking cavity, there are two door bodies, each of which opens and closes one of the small cooking cavities. A second trigger switch for detecting whether the door is closed is provided on the top wall of the small cooking cavity. When the door is closed, the second trigger switch is triggered by the door. The provision of the second trigger switch makes control safer.

[0012] Preferably, the lower edge of the door body is hinged at the lower part of the front end of the machine body, so that the door body can be opened by flipping down; the inner top of the small cooking cavity is provided with a positioning pin that can move up and down, and the positioning pin is kept moving down and exposed by a spring, and the top surface of the door body is provided with a triangular positioning block, and when the door body is closed, the positioning pin passes over the positioning block to form a certain resistance to the door body. The cooperation between the positioning pin and the positioning block makes the door opening and closing feel certain, and a certain force is required to open or close it.

[0013] As a further improvement, the front end surface of the machine body has a stopper extending forward, and when the door body is closed, the stopper blocks the top surface of the door body, and the second trigger switch and the positioning pin are both arranged on the stopper. The stopper can move the door body out, making the cooking cavity more independent, and the stopper can block the top surface of the door body, making the appearance more integrated and beautiful, and the stopper provides a suitable installation position for the second trigger switch and the positioning pin. Of course, the closed door body can also be embedded in the cooking space.

[0014] As an improvement, a first sealing strip is provided at the periphery of the front end face of the above-mentioned machine body, and a second sealing ring is provided at intervals on the left and right sides of the front end face of the partition. When the door body is closed, the first sealing strip forms a seal between the back of the door body and the front end face of the machine body, and the second sealing ring forms a seal between the back of the door body and the front end face of the partition. The provision of the sealing strip can avoid air leakage as much as possible, and the heating efficiency is higher.

[0015] Preferably, the air inlet is arranged at the top of the body, and the exhaust port is arranged at the back of the body; of course, the arrangement of the air inlet and the exhaust port can also refer to the existing air fryer structure. In order to process more food at the same time in one cooking space, preferably, the first ribs located on the inner wall on the same side of the large cooking cavity are two and are arranged at intervals up and down, and the second ribs located on the same side of the partition are also two and are arranged at intervals up and down.

[0016] As a further improvement, the partition is hollow inside, and a plurality of exhaust holes are provided on the top of the partition. When the hot air assembly works, the hot air in the partition can be extracted through the exhaust holes. The partition is generally made of PCB board, and the hollow design combined with the exhaust hole is conducive to cooling the partition.

[0017] Compared with the prior art, the advantages of the air fryer are: through the setting of a detachable partition, the large cooking cavity can be isolated into two independent small cooking cavities with a left and right interval, which makes the air fryer have two usage modes, one is the large cooking cavity working mode without partition, which is suitable for processing larger food, and the other is the double small cooking cavity working mode after the partition is installed, which can be easily switched according to needs. This mode can process a variety of different ingredients at the same time without cross-flavoring each other; in addition, it is important that a door body that can open and close the large cooking cavity is provided at the front end of the machine body, and the door body can close the mouth of the large cooking space, so there is no need to set up an additional inner pot, which reduces the cost, and the setting of the first convex rib and the second convex rib can facilitate the placement of the baking tray thereon, and different sizes of baking trays can be used for different usage modes. When in use, the baking tray with food is placed on the corresponding convex rib, and finally the door body is closed. The grease is mainly concentrated on the baking tray, and the cleaning of the baking tray is more convenient than the pot body.

[0018] The second technical problem to be solved by the present invention is to provide a control method for the aforementioned air fryer with a more optimized control mode.

[0019] The technical solution adopted by the present invention to solve the above-mentioned second technical problem is: a control method, characterized in that: it includes the aforementioned air fryer, and also includes the following classification control steps; when the first trigger switch is not triggered, it enters the whole cavity working mode, and only when the two second trigger switches respectively detect that the two door bodies are closed, the two hot air components can work, otherwise, the hot air components do not work; when the first trigger switch is triggered by the inserted partition, it enters the dual cavity working mode, if the second trigger switch detects that the corresponding door body is closed, the hot air component corresponding to the small cooking cavity can work, if the second trigger switch does not detect that the corresponding door body is closed, the hot air component corresponding to the small cooking cavity cannot work.

[0020] As a preferred solution, in the whole-cavity working mode, the two hot air assemblies work alternately and at intervals. This mode can heat the food more evenly.

[0021] Compared with the prior art, the advantages of the control method of the air fryer are: the control method is completely different from the traditional air fryer control method, the heating part of each small cooking cavity is independently controlled, one small cooking cavity can be used independently, or two cooking cavities can be used at the same time, the control is more humane and more energy-saving; according to whether the first trigger switch is triggered by the partition or not, a signal can be given to the control panel, and the control panel can know whether it is a whole-cavity working mode or a dual-cavity working mode, which is conducive to precise control.

[0036] The present invention is further described in detail below with reference to the accompanying drawings.

[0037] like Figures 1 to 13 Shown is a preferred embodiment of the air fryer of the present invention.

[0038] An air fryer capable of cooking different ingredients at the same time, comprising

[0039] The machine body 1 has a large cooking cavity 1a formed therein with its opening facing forward, and an air inlet 11 and an air outlet 12 are provided on the machine body 1.

[0040] The hot air component 2 is arranged in the body 1 and above the large cooking cavity 1a. The hot air component 2 can send high-temperature gas into the large cooking cavity 1a. Specifically, the hot air component 2 includes a heating element, a heat circulation fan, a cooling fan and a motor. The heat circulation fan is located above the heating element, and the motor is located above the heat circulation fan and below the cooling fan. Its power output end is connected to the heat circulation fan in a transmission manner so that the heat circulation fan blows the heat generated by the heating element into the cooking cavity, removes moisture from the food through the hot air and heats the food, thereby achieving the effect and taste of frying various foods, French fries, fish and other fried foods. The hot air component 2 can refer to the existing air fryer.

[0042] In this embodiment, there are two hot air components 2 that work independently of each other, each hot air component 2 corresponds to one of the small cooking chambers 1b, there are two groups of exhaust ports 12, each exhaust port 12 corresponds to one of the small cooking chambers 1b. The air inlet 11 is provided at the top of the machine body 1, and the exhaust port 12 is provided at the back of the machine body 1.

[0043] A slide groove 1a1 is provided at the bottom of the large cooking cavity 1a along the front-to-back direction, and a dowel 51 is provided at the bottom of the partition 5 for plugging into the slide groove 1a1. A first trigger switch 7a is provided at the inner top of the large cooking cavity 1a for detecting whether the partition 5 is assembled into the large cooking cavity 1a. When the partition 5 is assembled into the large cooking cavity 1a, the first trigger switch 7a is triggered by the top of the partition 5.

[0044] There are two door bodies 6, each door body 6 opens and closes one of the small cooking cavities 1b, and the top wall of the small cooking cavity 1b is provided with a second trigger switch 7b for detecting whether the door body 6 is closed or not. The top surface of the door body 6 is provided with a rib 63 that cooperates with the second trigger switch 7b to trigger it. When the door body 6 is closed, the second trigger switch 7b is triggered by the rib 63 of the door body 6.

[0045] The lower edge of the door body 6 is hinged at the lower part of the front end of the machine body 1 so that the door body 6 can be opened by flipping down, and each door body 6 is provided with a handle 62; the inner top of the small cooking cavity 1b is provided with a locking pin 8 that can move up and down, and the locking pin 8 is kept downward and exposed by the action of a spring 81, and the top surface of the door body 6 is provided with a triangular locking block 61, and when the door body 6 is closed, the locking pin 8 passes over the locking block 61 to form a certain resistance to the door body 6.

[0046] The front end surface of the machine body 1 has a top stop 13 extending forward. When the door body 6 is closed, the top stop blocks the top surface of the door body 6 . The second trigger switch 7 b and the locking pin 8 are both arranged on the top stop 13 .

[0047] A first sealing strip 9a is provided on the periphery of the front end face of the machine body 1, and a second sealing ring 9b is provided on the front end face of the partition 5 with a left and right interval. When the door body 6 is closed, the first sealing strip 9a forms a seal between the back side of the door body 6 and the front end face of the machine body 1, and the second sealing ring 9b forms a seal between the back side of the door body 6 and the front end face of the partition 5.

[0048] The partition 5 is hollow inside, and a plurality of exhaust holes 52 are provided on the top of the partition 5 . When the hot air assembly 2 is in operation, the hot air in the partition 5 can be extracted through the exhaust holes 52 .

[0049] By setting a detachable partition, the large cooking cavity 1a can be isolated into two independent small cooking cavities 1b set at intervals on the left and right. In addition, a door body 6 that can open and close the large cooking cavity is provided at the front end of the machine body 1. The door body 6 can close the mouth ends of the large cooking space 1a and the small cooking space 1b, so that a closed cooking space can be formed without the need for an additional inner pot.

[0050] The air fryer has two usage modes. One is the working mode of the large cooking cavity 1a without the partition 5. Fig.13 As shown in FIG. 1 , this mode is suitable for processing relatively large food. Another mode is the double small cooking chamber 1b working mode after the partition 5 is installed, such as Figures 1 to 3, 8 to 12, it can be easily switched according to needs. This mode can process a variety of different ingredients at the same time without mixing flavors with each other. The setting of the first convex rib 3a and the second convex rib 3b can facilitate the placement of a large baking tray 4a or a small baking tray 4b thereon. Different sizes of baking trays can be used in different usage modes. When in use, place the baking tray with food on the corresponding convex rib, and finally close the door body 6. The grease is mainly concentrated on the baking tray, and the cleaning of the baking tray is more convenient than that of the pot body.

[0051] Fig.14 As shown, it is a preferred embodiment of the control method of the aforementioned air fryer.

[0052] A control method, including the air fryer of the aforementioned embodiment, further includes the following classification control steps: when the first trigger switch 7a is not triggered, the whole cavity working mode is entered, and only when the two second trigger switches 7b respectively detect that the two doors 6 are closed, the two hot air components 2 can work, otherwise, the hot air components 2 do not work; when the first trigger switch 7a is triggered by the inserted partition 5, the double cavity working mode is entered, if the second trigger switch 7b detects that the corresponding door 6 is closed, the hot air component 2 corresponding to the small cooking cavity 1b can work, if the second trigger switch 7b does not detect that the corresponding door 6 is closed, the hot air component 2 corresponding to the small cooking cavity 1b cannot work. In the whole cavity working mode, the two hot air components 2 work alternately.

[0053] This control method is completely different from the traditional air fryer control method. The heating part of each small cooking cavity 1b is controlled independently. One small cooking cavity 1b can be used independently, or two small cooking cavities 1b can be used at the same time. The control is more humane and energy-saving. According to whether the first trigger switch 7a is triggered by the partition 5, a signal can be given to the control panel 10, and the control panel 10 can know whether it is a whole-cavity working mode or a double-cavity working mode, which is conducive to precise control.
