Description

Technical Field

[0001] This invention relates to an electric heating cooking appliance, specifically a multi-purpose electric heating cooking appliance. Background Technology

[0002] An air fryer is an electric cooking appliance that uses hot air to cook food, achieving the effect of air frying. Specifically, the heating element and the fan are powered on separately. The fan creates convection air, and the heating element heats the convection air, turning it into hot air. This high-temperature hot air circulates within a closed cavity, air-frying the food inside. However, during cooking, grease and other substances released from the heated food mix with the circulating hot air and reach accessible areas of the cavity and the appliance itself. This results in a thick layer of grime forming on the cavity and appliance after prolonged use. The cavity is typically open, making cleaning relatively easy. However, the appliance itself, with its non-removable heating element and fan, is much more difficult to clean. Failure to thoroughly clean the heating element and fan over a long period can seriously impact the user experience and health.

[0003] In addition, existing air fryers can only heat and cook food in air frying mode, which is a single function and cannot meet the different cooking requirements of different consumers, thus limiting the popularization of air fryers. To address the aforementioned issues, cooking appliances with both air-frying and grilling functions have emerged on the market. For example, Chinese patent document CN210276928U discloses a multi-functional oven, specifically comprising: a base with a receiving groove on its upper surface; a mounting seat on the rear side of the receiving groove; and a sealing cover movably connected to the mounting seat. When the sealing cover is closed, the inner end face of the receiving groove, the side wall of the mounting seat, and the inner end face of the sealing cover cooperate to form a cooking chamber. Inside the cooking chamber, from top to bottom, are arranged a grill rack, a grill rack heating mechanism, and an oil drip tray, with the grill rack heating mechanism heating the grill rack. A hot air baking mechanism is located within the mounting seat, and a hot air vent is located on the side wall of the mounting seat opposite the cooking chamber, connecting the cooking chamber and the hot air baking mechanism. An oil extraction chamber is located below the hot air baking mechanism on the mounting seat, and an oil fume extraction mechanism is located within the oil extraction chamber, connected to the cooking chamber. A controller is located on the base, and the grill rack heating mechanism, the hot air baking mechanism, and the oil fume extraction mechanism are all electrically connected to the controller. In this structure, a grill heating mechanism is set up to realize the grilling of food, and a hot air baking mechanism is set up to realize the baking of food. That is, corresponding heating components are set up for different cooking modes. This is because there is no heating module on the market that is universal for different cooking modes, which leads to the disadvantages of this multi-functional oven, such as complex overall structure, high manufacturing cost, and troublesome operation.

[0004] Therefore, further improvements are needed. Summary of the Invention

The heating component is connected to the controller through the disassembly structure circuit in a combined state. The disassembly structure includes a first connecting part on the heating component, and a second connecting part and a third connecting part on the machine body. When the first connecting part and the second connecting part are connected to each other, the heating component is located at station one. When the first connecting part and the third connecting part are connected to each other, the heating component is located at station two.

[0012] A locking mechanism is provided between the heating component and the machine body. The heating component is connected to the machine body through the locking mechanism so that the heating component is held at station one or station two. The locking mechanism includes a hook provided on the heating component and a locking pin that is repositioned and movable on the machine body. The hook is provided with a slot. When the locking mechanism is locked, the locking pin is at least partially embedded in the slot to engage with the hook.

[0013] The machine body is equipped with a switch for switching working modes, and the switch circuit is connected to the controller; when the locking mechanism is locked, the hook triggers the switch.

[0014] The heating element is embedded inside the support body; or, the support body has a receiving cavity, and the heating element is disposed in the receiving cavity.

[0015] It also includes a hot air duct and a heating chamber for containing food; in the first working mode, the hot air duct is connected to the heating chamber through a through hole structure, and a fan assembly for generating convective air is provided on the hot air duct, and the fan assembly is electrically connected to the controller; the heating assembly on the first workstation is located between the hot air duct and the heating chamber.

[0016] One end of the through-hole structure is opened on one end face of the support body, and the other end of the through-hole structure is opened on the other end face of the support body; the support part is disposed on either end face of the support body; the heating element is misaligned with the through-hole structure.

[0017] The hot air duct and the fan assembly are respectively installed on the body; the body is provided with a clearance through hole that connects to the hot air duct and corresponds to the fan assembly; the fan assembly is detachably installed on the body and can be removed through the clearance through hole.

[0018] The machine body is equipped with a rotating mechanism for driving the oil receiving tray to rotate. In the first working mode, the second work station is equipped with an oil receiving tray, and a grilling rack for loading food is detachably installed on the oil receiving tray.

[0041] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0042] First Embodiment

[0043] See Figures 1-13The electric cooking appliance involved in this embodiment includes a body 1, a controller 2, and a heating component 4. The heating component 4 is electrically connected to the controller 2, and the controller 2 is located on the top of the body 1. The body 1 is provided with a workstation a and a workstation b. The heating component 4 is movably connected to the body 1. The heating component 4 includes a heating element 401 and a support body 402. In this embodiment, the heating element 401 is preferably a heating tube, which can be configured with different structures, including spiral, U-shaped, and bow-shaped. The heating element 401 is located inside the support body 402. The support body 402 has through holes for ventilation. Structure 404 and support 403 for supporting cooking utensils (including frying pans or baking pans); when the heating component 4 moves relative to the body 1 to station a, the heating component 4 operates in working mode one, and the electric cooking appliance can perform air fry mode; when the heating component 4 moves relative to the body 1 to station b, the heating component 4 operates in working mode two, and the electric cooking appliance can perform grilling mode; when the heating component 4 leaves station a or station b, the user can easily clean station a or station b, effectively keeping it clean and tidy, and ensuring the user's health.

[0044] In this electric cooking appliance, the heating element 4 is movable relative to the main body 1. When the heating element 4 is not in station a, station a and its corresponding components can be cleaned; when the heating element 4 is not in station b, station b and its corresponding components can be cleaned. Therefore, this multi-purpose electric cooking appliance is easy to clean, effectively ensuring the user's experience and health. The heating element 4 is movable relative to the main body 1. When the heating element 4 is in station a, the air frying function can be realized; when the heating element 4 is in station b, the grilling function can be realized. Thus, this electric cooking appliance, by setting up a set of heating elements 4 and adjusting the heating element 4 to different usage states, can realize corresponding cooking modes, meeting the different cooking needs of different consumers. The heating component 4 is composed of a heating element 401 and a support 402. The support 402 is wrapped around the outside of the heating element 401. Compared with the irregular structure of the heating element 401, the regular structure of the support 402 is easier to clean, so as to keep the heating component 4 clean and hygienic, thereby improving the user experience of electric cooking appliances. Cleaning can also effectively prevent the growth of bacteria in the heating component 4 and ensure the health of users. The through-hole structure 404 on the support 402 can be used for ventilation, and the support part 403 can support cooking utensils. Therefore, this heating component 4 can be used in air fryer products as well as grill products, with a wide range of applications and strong versatility.

[0045] Furthermore, the machine body 1 includes a vertically arranged standing body 101 and a horizontally arranged support base 102. The bottom end of the standing body 101 is connected to one end of the support base 102, so that the machine body 1 is L-shaped as a whole. Station 1a is the vertical surface (or the inclined surface that is inclined relative to the horizontal plane) on the inner side of the standing body 101. The vertical surface is a plane that is basically perpendicular to the horizontal plane. Station 2b is the plane on the top of the support base 102. The plane is a basically horizontal plane.

[0046] Furthermore, the bottom end of the heating component 4 is hinged to the machine body 1 via a rotating shaft 6, with the hinge point located between workstation a and workstation b. When the heating component 4 is rotated upward relative to the machine body 1 to workstation a, the heating component 4 operates in working mode one, which is vertical operation, thus meeting the requirements of the air frying mode. When the heating component 4 is rotated downward relative to the machine body 1 to workstation b, the heating component 4 operates in working mode two, which is horizontal operation, thus meeting the requirements of the grilling mode.

[0047] Furthermore, a locking mechanism is provided between the heating component 4 and the machine body 1. The heating component 4 is connected to the machine body 1 through the locking mechanism to keep the heating component 4 at station a or station b. In this embodiment, when the heating component 4 is adjusted to station a, the heating component 4 is in a standing state that is easy to fall over, so the locking mechanism is provided between the heating component 4 and station a. When the heating component 4 is adjusted to station b, the position of the heating component 4 is relatively stable, so the locking mechanism may not be provided between the heating component 4 and station b. Of course, depending on the needs of different structures, a locking mechanism may be provided between the heating component 4 and station b.

[0048] Further, see Figure 10 and Figure 11In this embodiment, the locking mechanism is a manual locking and unlocking mechanism, which allows users to easily lock and unlock with simple actions. Specifically, the locking mechanism includes a hook 11 set at the top of the heating component 4 and a locking pin 12 that is movably set on the machine body 1 (the upper part of the standing body 101) with up-and-down reset. The hook 11 has an integrally formed groove 1101. A locking hole 104 is opened on the upper part of the inner side of the standing body 101. The locking hole 104 corresponds to the ends of the hook 11 and the locking pin 12 respectively. When the heating component 4 is flipped to the work position 1a, the hook 11 passes through the locking hole 104 and extends into the interior of the standing body 101 to engage with the locking pin 12. When the locking mechanism is in the locked state, the bottom end of the locking pin 12 is embedded in the slot 1101 to engage with the hook 11, thereby keeping the heating component 4 in position a. The end of the hook 11 has two sets of inclined structures. One set of inclined structures is used to guide the end of the locking pin 12 into the slot 1101 when locking, and the other set of inclined structures is used to guide the end of the locking pin 12 out of the slot 1101 when unlocking, so that the user can manually lock and unlock. A return spring 13 is provided between the locking pin 12 and the standing body 101. The return spring 13 drives the locking pin 12 to slide downward relative to the standing body 101 to ensure the stability of the engagement between the hook 11 and the locking pin 12.

[0049] Furthermore, a switching switch 14 for switching working modes is provided on the body 1 (inside the standing body 101). The switching switch 14 is connected to the controller 2. When the locking mechanism is locked, the hook 11 triggers the switching switch 14. The triggered switching switch 14 will send a signal to the controller 2 in a timely manner. After receiving the relevant signal, the controller 2 will execute corresponding measures according to the set program to ensure that the air blast mode is carried out smoothly.

[0050] Furthermore, in this embodiment, the heating element 401 is pre-embedded inside the support 402, that is, the heating element 401 and the support 402 are integrally formed, which makes the whole body stronger, the heat transfer effect better, and the heat loss rate lower; the support 402 is made of high temperature resistant materials, such as metal, stone, ceramics, etc.

[0051] Furthermore, this electric cooking appliance also includes a hot air duct 103 and a heating chamber for containing food. The hot air duct 103 is located inside the body 1. In operating mode one, the hot air duct 103 is connected to the heating chamber through a through-hole structure 404. A fan assembly 9 for generating convective air is installed inside the hot air duct 103, and the fan assembly 9 is electrically connected to the controller 2. The heating component 4 on station a is located between the hot air duct 103 and the heating chamber. When the heating component 4 and the fan assembly 9 are powered on, convective hot air is generated between the hot air duct 103 and the heating chamber to achieve an air frying cooking mode.

[0052] Furthermore, one end of the through-hole structure 404 is opened on one end face of the support body 402, and the other end of the through-hole structure 404 is opened on the other end face of the support body 402, so that the two end faces on the support body 402 are connected to each other, thereby allowing air convection to be formed between the two end faces. In the air blast mode, hot air passes through the through-hole structure; the support part 403 is provided on either end face of the support body 402; in order to avoid structural interference between the heating element 401 and the through-hole structure 404, the heating element 401 and the through-hole structure 404 are misaligned and fitted, resulting in a compact structure.

[0053] Furthermore, the hot air duct 103 and the fan assembly 9 are respectively installed on the body 1; the inner side of the body 1 is provided with a clearance through hole 105 that connects to the hot air duct 103 and corresponds to the fan assembly 9. The clearance through hole 105 is opened on station a. When the heating component 4 moves to station a, the clearance through hole 105 is closed; the fan assembly 9 is detachably installed on the body 1 and removed through the clearance through hole 105. During cleaning, the heating component 4 is adjusted away from station a, and the fan assembly 9 is exposed through the clearance through hole 105. The removed fan assembly 9 can be taken out through the clearance through hole 105 so that the fan assembly 9 can be disassembled and cleaned to ensure that the fan assembly 9 is thoroughly cleaned.

[0054] Furthermore, this electric cooking appliance also includes a detachable cover 3 mounted on the body 1. The body 1 and the cover 3 together form a heating cavity for containing food. Station 1a is located on the side of the heating cavity, and station 2b is located at the bottom of the heating cavity. Specifically, the cover 3 has two open sides. One open side of the cover 3 covers the inner side of the standing body 101 to cover station 1a; the other open side of the cover 3 covers the top surface of the support base 102 to cover station 2b; the openings on both sides of the cover 3 are closed by the inner side of the standing body 101 and the top surface of the support base 102, respectively, so that the inner cavity of the cover 3 forms a sealed heating cavity.

[0055] Furthermore, the heating assembly also includes a linkage 15 for mounting and connecting the machine body 1, meaning that the heating assembly is rotatably mounted and connected to the machine body 1 via the linkage 15. The linkage 15 is fixed (or detachable) on the side of the support body 402. To facilitate the rotatable mounting connection, rotating shafts 6 are respectively provided on the two axial ends of the linkage 15 to achieve the rotatable connection. The electrical terminal of the heating element 401 extends out of the support body 402. A clearance slot (not shown in the figure) is provided on the linkage 15, through which the electrical terminal of the heating element 401 passes so that the heating element 401 can be electrically connected to the corresponding control circuit.

[0056] Furthermore, the body 1 is provided with a rotating mechanism for driving the oil receiving tray 5 to rotate. The rotating mechanism includes a drive motor (not shown in the figure) and a coupling component 8. The drive motor drives the coupling component 8 to rotate through a transmission assembly (not shown in the figure). The drive motor circuit is connected to the controller 2. The bottom of the oil receiving tray 5 is provided with a coupling structure that cooperates with the coupling component 8; see also Figure 3 and Figure 4 In working mode one, station two (b) is equipped with an oil collection tray 5 to collect the grease produced during food heating. A detachable grill rack 7 is mounted on the oil collection tray 5 to hold the food. The grill rack 7 rotates within the heating chamber along with the oil collection tray 5, ensuring more even heating of the food and resulting in better cooking outcomes. See also... Figure 5 and Figure 6 In the second working mode, the cooking utensil is detachably mounted on the top of the heating element 4. The cooking utensil is a griddle 10 that can perform frying and grilling functions. The griddle 10 receives the heat generated by the heating element 4 and then frys and grills the food.

[0057] Second Embodiment

[0058] The electric cooking appliance involved in this embodiment differs from the first embodiment in that the heating component 4 is detachably mounted on the body 1.

[0059] Furthermore, a disassembly and assembly structure is provided between the heating component 4 and the machine body 1. The heating component 4 is connected to the controller 2 through the disassembly and assembly structure in its combined state. The disassembly and assembly structure includes a first connecting part 16 (the first connecting part 16 replaces the linkage 15 in the first embodiment) located at one end of the heating component 4, and a second connecting part 17 and a third connecting part 18 located on the machine body 1. When the first connecting part 16 and the second connecting part 17 are connected to each other, the heating component 4 is located at station a. When the first connecting part 16 and the third connecting part 18 are connected to each other, the heating component 4 is located at station b. Specifically, the first connecting part 16 is a male connector, the second connecting part 17 is a horizontally extending female connector, and the third connecting part 18 is a vertically extending female connector. The first connecting part 16 is plugged into the second connecting part 17 or the third connecting part 18. The second connecting part 17 or the third connecting part 18 that is not connected to the first connecting part 16 is sealed by a waterproof component to prevent water from getting in.

[0060] Furthermore, the support body 402 is a disc formed by stamping metal parts, and a receiving cavity 405 is formed inside the support body 402, in which the heating element 401 is disposed.
