Description

Technical Field

[0001] The utility model relates to the field of frying and grilling utensils, in particular to a frying and grilling machine which is easy to clean. Background Art

[0002] At present, there is a type of grilling machine on the market, in which both the upper grill assembly and the lower grill assembly can heat and cook food. In order to improve the heating effect of the upper grill assembly, an upper heating tube with a larger density distribution is usually used. The upper heating tube is arranged on the inner surface of the upper cover, and in order to ensure that the heat of the upper heating tube is fully transferred to the food, the upper heating tube is exposed or covered with a layer of filter under it, so that when the upper grill assembly and the lower grill assembly are covered, the heat of the upper heating tube can be fully utilized to heat the food. However, during the use of the above-mentioned product, the oil stains from cooking food are easily attached to the inner surface of the upper cover, and because the upper heating tube is fixed on the inner surface of the upper cover and is densely distributed, it is difficult to clean the inner surface of the upper cover, which adds cleaning troubles to users.

[0003] In order to facilitate the user to wipe the inner surface of the upper cover, there are some existing solutions such as patent CN218009398U, which discloses a grilling machine, in which the heating tube is rotatably connected to the reflective plate, and the purpose of conveniently cleaning the inner shell surface can be achieved by flipping the heating tube. In this solution, in order to realize the rotational installation of the heating tube, a first fixing plate is integrally formed on the heating tube, and the first fixing plate and the second fixing plate are respectively arranged on both sides of the rotating matching member, and screws are inserted into the corresponding positions of the first fixing plate and the second fixing plate to realize locking the heating tube on the reflective plate. The structure is relatively complex, and since a sliding part is provided at the position of the locking screw on the first fixing plate, which is used to slide along the slide groove of the rotating matching member to limit the flipping angle of the heating tube, the frequent flipping of the heating tube is likely to cause the locking effect of the first fixing plate and the second fixing plate to deteriorate, which will be not conducive to the long-term stable fixation of the heating tube, and the sliding part slides along the slide groove. The reliability is low, and the phenomenon of the heating tube flipping and stagnation is likely to occur, resulting in the heating tube flipping not being smooth, which limits the efficiency of the heating tube flipping.

[0048] like Figures 1 to 8As shown, the present application provides a grilling machine that is easy to clean, including an upper grill assembly 10, the upper grill assembly 10 includes an outer cover 12, an inner cover 13 arranged in the outer cover 12, and a heating tube 14 installed in a receiving cavity 131 of the inner cover 13, a raised mounting portion 15 is provided in the receiving cavity 131, a side wall of the mounting portion 15 is provided with a mounting hole 151, the heating tube 14 is rotatably connected to the mounting hole 151, the heating tube 14 includes a heating section 141 and a mounting hole 151 arranged at the end of the heating section 141. The inner cover 13 has a mounting end 142, and the outer surface of the inner cover 13 forms a mounting groove 16 corresponding to the mounting portion 15. The mounting end 142 extends from the mounting hole 151 into the mounting groove 16. A collar 17 is provided in the mounting groove 16. The collar 17 is sleeved on the outer side wall of the mounting end 142 and is tightly matched with the mounting end 142. The collar 17 cooperates with the outer side wall stopper of the mounting hole 151 to limit the mounting end 142 of the heating tube 14 from retreating to the accommodating cavity 131 during the rotation process.

[0049] In the grilling machine that is easy to clean, the heating tube 14 is rotatably installed on the inner cover 13. When the inner surface of the inner cover 13 needs to be cleaned, the heating tube 14 can be flipped away from the inner surface of the inner cover 13 for user convenience, which provides operation convenience for the user and is conducive to improving the cleaning effect.

[0050] The mounting end 142 extends out of the inner cover 13 in the mounting groove 16, which can not only meet the requirements of the rotational installation of the heating tube 14, but also prevent the mounting end 142 from getting wet and causing a short circuit during the cleaning of the inner cover 13, thereby achieving waterproof protection and improving the safety of the product.

[0051] The collar 17 is used to restrict the mounting end 142 of the heating tube 14 in the mounting groove 16, so as to provide a stable and secure mounting of the heating tube 14, and to prevent the mounting end 142 from moving inward into the accommodating cavity 131 or even coming out of the mounting hole 151 during the rotation of the heating tube 14, thereby causing the installation failure of the heating tube 14, that is, to ensure that the heating tube 14 can be turned over stably and reliably for use; the collar 17 has a simple structure, which is conducive to reducing costs and simplifying the assembly process.

[0052] Specifically, the heating pipe 14 in the upper grill assembly 10 of the present application is installed in a rotating manner, and the grilling machine further includes a lower grill assembly 11. There is no limitation on how to install the heating pipe of the lower grill assembly 11. For example, the lower grill assembly 11 includes a lower grill and a base, and the heating pipe can be directly installed on the lower grill or in the base. Figure 1As shown, when the upper grill assembly 10 covers the lower grill assembly 11, the accommodating cavity 131 forms a part of the cooking cavity. During the food processing, oil stains, water stains, etc. will adhere to the inner surface of the inner cover 13, so the inner surface of the inner cover 13 needs to be cleaned frequently. The rotating setting of the heating tube 14 provides convenience for users to clean the inner cover 13. Figure 1 In the example, the upper baking tray is not provided. Of course, in other examples, the upper baking tray assembly 10 may include a filter screen, which covers the heating tube 14. However, since the filter screen has a porous structure, oil stains, water stains, etc. will still pass through the mesh and adhere to the inner surface of the inner cover 13. Therefore, the inner surface of the inner cover 13 still needs to be cleaned.

[0053] like Figure 1 and Figure 2 As shown, the heating tube 14 has a first position (such as Figure 1 ) and flipped away from the second position of the inner surface of the inner cover 13 (such as Figure 2 ), when the inner surface of the inner cover 13 needs to be cleaned, the heating tube 14 is moved to the second position, at which time the heating tube 14 is located below the hand, which is convenient for the user to wipe the inner surface of the inner cover 13. Further, in order to keep the heating tube 14 in the first position for operation, Figure 1 or Figure 4 As shown, a locking piece 18 is provided on the inner surface of the inner cover 13, and one end of the heating tube 14 away from the mounting portion 15 is locked or unlocked with the locking piece 18. Locking the heating tube 14 with the locking piece 18 can ensure that the heating tube 14 remains stable during operation, thereby improving reliability of use.

[0054] Regarding the collar 17, after the collar 17 is installed in place, the collar 17 and the mounting end 142 are relatively fixed, which can prevent the mounting end 142 from moving back along the collar 17 into the accommodating cavity 131. In addition, the collar 17 is limited in the mounting groove 16, so that the mounting end 142 can be stably and securely limited, which can prevent it from being separated from the inner cover 13 and causing the installation failure of the heating pipe 14, thereby ensuring the reliability of the installation and use of the heating pipe 14. In one embodiment, the collar 17 is a non-enclosed structure in the circumferential direction, which is conducive to the installation end 142; in another embodiment, the collar 17 is a closed structure in the circumferential direction, and the design is relatively simple.

[0055] As a preferred embodiment of the present application, the collar 17 is a metal sheet, which surrounds the mounting end 142 circumferentially and forms an opening 171 in the circumferential direction. The inner diameter of the collar 17 is adjustable through the opening 171 .

[0056] like Figure 5 and Figure 6As shown, the collar 17 is formed by bending a metal sheet, and the two ends of the metal sheet are not connected but form an opening 171. Relevant personnel can adjust the inner diameter of the collar 17 by bending the opening 171, making it easier to fit the mounting end 142. Furthermore, the material of the metal sheet is less affected by temperature, which can reduce the deformation rate and improve the reliability of use.

[0057] Furthermore, outwardly extending baffles 172 are respectively provided at both ends of the metal sheet forming the opening 171, and fasteners 173 are passed through the two baffles 172 to fasten the ring 17 with the mounting end 142, and the baffles 172 extend axially along the ring 17 to cooperate with the outer side wall stop of the mounting hole 151.

[0058] like Figure 5 As shown, one function of the baffle 172 is that it can act as an operating component. The relevant personnel can increase the inner diameter of the collar 17 by bending the two baffles 172 outward so that the mounting end 142 can be inserted, and then the inner diameter of the collar 17 can be reduced by squeezing the two baffles 172 inward so that the collar 17 and the mounting end 142 can be tightly matched. Another function of the baffle 172 is that it can provide a mounting position for the fastener 173. The fastener 173 is, for example, a screw. By locking the screw, the collar 17 and the mounting end 142 can always be kept tightly matched, which can optimize the stability of the installation of the collar 17. Another function of the baffle 172 is that one end of it can be pressed against the side wall of the mounting groove 16, so that the collar 17 can be limited and the mounting end 142 can be prevented from retreating into the accommodating cavity 131.

[0059] As a preferred embodiment of the present application, the mounting end 142 includes a cylindrical section 1421 and a sheet-shaped connecting terminal 1422 connected to the end of the cylindrical section 1421, the ring 17 is sleeved on the outside of the cylindrical section 1421, the ring 17 has a first end close to the mounting hole 151 and a second end away from the mounting hole 151, and the connecting terminal 1422 abuts against the end face of the second end.

[0060] like Figure 5 and Figure 6 As shown, after the collar 17 is installed in place, the width of the connection terminal 1422 is greater than the inner diameter of the collar 17, which can prevent the connection terminal 1422 from sliding into the collar 17 or even moving inward into the accommodating cavity 131 and breaking away from the connection with the inner cover 13, providing a limit between the installation end 142 and the collar 17, which can further reduce the probability of the installation end 142 retreating during the rotation of the heating tube 14, thereby improving the reliability of use; and the connection terminal 1422 is exposed outside the collar 17, which is convenient for connection with the circuit, so that the heating tube 14 can be powered on. Because the outer cover 12 is provided, the outer cover 12 can close the installation groove 16, thereby providing dust and water protection, and avoiding safety problems caused by water entering the wiring position.

[0061] Furthermore, an end portion of the first end is provided with an outer flange 174 extending radially outward, and the outer flange 174 is engaged with an outer side wall stopper of the mounting hole 151 .

[0062] By providing the outer flange 174, the collar 17 can be limited in position in the mounting groove 16, and there is no relative movement between the mounting end 142 and the collar 17, so that the mounting end 142 cannot be retracted into the accommodating cavity 131. The outer flange 174 can be an annular structure, or a plurality of ribs or sheet structures spaced apart along the circumferential direction, which is not limited in the present application.

[0063] It is understandable that in other embodiments, the outer flange 174 can be omitted. In this case, the ring 17 has a larger wall thickness, and the outer diameter of the ring 17 is larger than the diameter of the mounting hole 151. The end of the ring 17 can be directly placed against the side wall of the mounting groove 16 to achieve positioning.

[0064] As a preferred embodiment of the present application, the collar 17 is an annular silicone sleeve, and the silicone sleeve is interference fit with the mounting end 142 .

[0065] In this embodiment, the deformation property of silicone can be used to make the mounting end 142 fit into the sleeve ring 17, and the silicone sleeve has a simple structure and low cost. When the heat of the heating section 141 of the heating tube 14 is transferred to the silicone sleeve, the silicone sleeve can absorb part of the heat and prevent the heat from being transferred to the cold end.

[0066] As a preferred embodiment of the present application, the grilling machine further includes a lower grilling pan assembly 11, one end of the outer cover 12 is hingedly connected to the lower grilling pan assembly 11, and a handle 121 is provided at the top of the other end of the outer cover 12 for flipping the outer cover 12.

[0067] like Figure 4 As shown, a structure of a combination of inner and outer covers is adopted, and the heating tube 14 is arranged on the inner cover 13. The outer cover 12 can reduce the heat loss of the heating tube 14 to the outside, which helps to improve the heating efficiency. The outer cover 12 can also play a role of heat insulation, which can prevent the outer cover 12 from being too hot, and avoid the user from being burned by high temperature when opening the cover, which can improve the safety of the user.

[0068] Of course, in other embodiments, only one cover may be used to install the heating pipe 14 and to connect with the lower baking tray assembly 11 .

[0069] As a preferred embodiment of the present application, the inner top wall of the inner cover 13 is provided with a convex rib 19 protruding toward the heating tube 14 , and the convex rib 19 is provided with a plurality of ribs, and at least a portion of the ribs 19 extends along the extension direction of the heating section 141 .

[0070] like Figure 4As shown, by providing the convex rib 19, when part of the heat of the heating tube 14 is radiated toward the inner cover 13, the convex rib 19 can reflect the heat into the cooking cavity, thereby increasing the heat utilization rate and improving the heating effect of the upper baking tray assembly 10. Figure 7 As shown, the heating section 141 includes, for example, a plurality of U-shaped structures 1411 connected in sequence, each U-shaped structure 1411 includes two vertical straight tube sections 1412 and a connecting section 1413 connecting the two vertical straight tube sections 1412, wherein the connecting section 1413 can be a straight tube or an arc-shaped tube, which is not limited in this application. Preferably, four convex ribs 19 are connected in sequence to form an approximately rectangular structure, wherein two convex ribs 19 are parallel to the vertical straight tube sections 1412, and the convex ribs 19 at this position can be set longer so as to reflect more heat from the straight tube sections 1412 and reduce heat loss. Of course, in other embodiments, the convex ribs 19 can also be set in other numbers, and the convex ribs 19 can be arranged in other ways, such as multiple convex ribs 19 are arranged at intervals in a direction parallel to the vertical straight tube sections 1412.

[0071] On the basis of the above scheme, regarding the installation of the heating pipe 14 of the present application, in one embodiment, as Figure 2 and Figure 7 As shown, there are two mounting ends 142 , which are bent inward relative to the heating section 141 and are located on the same straight line. There is one mounting portion 15 , and both ends of the mounting portion 15 are provided with a mounting hole 151 .

[0072] In this embodiment, the two mounting ends 142 are respectively connected to the two ends of the mounting portion 15. The two mounting ends 142 are close to each other, which is beneficial to the stability of the flipping of the heating tube 14. When flipping, the two mounting ends 142 tend to approach each other, which can further prevent the mounting ends 142 from retreating into the accommodating cavity 131. In addition, the two mounting ends 142 can be aligned with the mounting portion 15 for installation at the same time, and the installation efficiency is high.

[0073] In another embodiment, Figure 3 and Figure 8 As shown, there are two mounting ends 142 , which are bent outward relative to the heating section 141 and are located on the same straight line. There are two mounting portions 15 which are arranged opposite to each other, and each mounting portion 15 has a mounting hole 151 .

[0074] In this embodiment, two mounting portions 15 can be arranged at two corners of the inner cover 13, so that the surface of most areas of the inner cover 13 is flat, which is conducive to cleaning and can improve the cleaning effect. The two mounting portions 15 can provide two support points to prevent the heating tube 14 from completely detaching from the inner cover 13, providing anti-detachment protection.

[0075] The technical solution protected by the present utility model is not limited to the above-mentioned embodiments. It should be pointed out that the combination of the technical solution of any embodiment with the technical solution of one or more other embodiments is within the protection scope of the present utility model.
