[0001] This application relates to the technical fields of kitchen appliances and kitchen utensils, and particularly to a self-rotating grill. Background Art

[0002] With the improvement of living standards, baked goods have become widely loved by people. Ovens, microwave ovens, etc. have become one of the necessary kitchen appliances in many families. In order to bake food evenly, a rotating grill is usually provided inside equipment such as ovens. In the prior art, equipment such as ovens transmits rotation to a rotary joint installed in a small hole provided on the inner rear wall of the machine cavity. When baking food, the prepared grill is taken into the machine cavity of the equipment for installation and the grill rotating shaft is inserted into the rotary joint. In actual operation, due to the depth of the machine cavity, the operator's line of sight is blocked, and it is very difficult for the grill rotating shaft to align with the rotary joint. In addition, for the preparation before baking and the picking up of the parts after baking, the grills in the prior art do not have a corresponding platform or base to support the operation, resulting in inconvenient operation and forming pain points.

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the protection scope of this application.

[0030] Please refer to Figure 1 , Figure 1 is the overall structure diagram of the self-rotating grill 10 including related devices provided by this application, that is, a cooking device in the aspect of kitchen utensils.

[0031] The cooking device includes a cooking appliance 2 and a self-rotating grill 10. The cooking appliance 2 includes, but is not limited to, an oven, a steam oven, a microwave oven, a grill, etc. The cooking appliance 2 is provided with a cabinet, and the cabinet is provided with a cooking chamber. When cooking food, the food to be cooked can be first inserted onto the skewers 210 of the self-rotating grill 10, and then the self-rotating grill 10 together with the food is placed into the cooking chamber. Then, the electric switch of the control circuit system 70 can be selectively pressed to start the rotation of the self-rotating grill 10. Then, close the door of the cooking appliance 2, and then turn on the power of the cooking appliance 2 to start, so that the temperature in the cooking chamber of the cooking appliance 2 rises, and then bake the food to be cooked.

[0032] Among them, the self-rotating grill 10 is configured to be movably plug-in in the cooking appliance 2. Exemplarily, the self-rotating grill 10 can be directly placed on the chassis of the cooking appliance 2 to operate. In this way, the self-rotating grill 10 provided in this embodiment can be adapted to different models of cooking appliances and facilities; it can also be installed on charcoal to operate. Thereby expanding the application scenarios of the self-rotating grill 10 and improving the practical value of this application. In daily life, the self-rotating grill 10 can be directly applied to the existing cooking appliance 2 at home for food baking, thus supplementing and perfecting the function of the cooking appliance 2 and meeting people's further pursuit of delicious food.

[0033] Please refer to Figure 1 , Figure 2 , Figure 2 which is a schematic structural diagram of the self-rotating grill 10.

[0034] For the convenience of description, in this application, the length direction of the self-rotating grill 10 is defined as the X-axis direction, the width direction is defined as the Y-axis direction, and the height direction is defined as the Z-axis direction. The X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other pairwise.

[0035] The self-rotating grill 10 includes a base 100, a rotating member 200, a heat insulation shell 30, and a transmission member 40. The rotating assembly 200, the heat insulation shell 30, and the transmission member 40 are all installed on the base 100.

[0036] Please combine Figure 2 , Figure 3 , Figure 3 which is Figure 2 a schematic structural diagram of the base 100 in the self-rotating grill 10 shown.

[0037] The machine base 100 includes a first vertical plate 111; a second vertical plate 112; a third vertical plate 113; a bottom plate 114; a connecting rod 115; a top plate 116; a bearing seat 117; and an inclined seat plate 118. The first vertical plate 111 and the second vertical plate 112 are arranged opposite to each other and spaced apart along the X-axis direction. The top plate 116 and the bottom plate 114 are respectively fixedly connected between the first vertical plate 111 and the second vertical plate 112 from top to bottom, and the intersection of the plates can be connected by a fixing method such as welding. The bottom plate 114 intersects with the X-axis and the Y-axis to form a coplanar plane. The bottom plate 114, the top plate 116, the first vertical plate 111 and the second vertical plate 112 are fixedly connected to form a box, namely the seat gallery 110. A pair of bearing mounting holes 1101 are respectively provided in the seat gallery 110 near the top plate 116, the first vertical plate 111 and the second vertical plate 112. The inclined seat plate 118 is located in the seat gallery 110 between the bottom plate 114 and the top plate 116, which are away from the plane formed by the intersection of the X-axis and the Z-axis, and is fixedly connected to the first vertical plate 111 and the second vertical plate 112. The seat gallery 110 accommodates and installs the heat insulation shell 30 and its associated components through the bearing function of the inclined seat plate 118.

[0038] In the X-axis direction, the second vertical plate 112 is fixedly connected to the third vertical plate 113 through the connecting rod 115, forming a platform for the rotation of the rotating member 200. When the rotating member 200 is combined with the above platform, the rotating shaft of the rotating member 200 is connected to the large wheel shaft 454 of the transmission member 40.

[0039] Please combine Figure 2 , Figure 3 and Figure 4 , Figure 4 It is a schematic diagram of the structure of key components of the self-rotating grill 10.

[0040] The heat-insulating shell 30 is located between the inclined seat plate 118 and the transmission member 40 and is supported and fixed by the inclined seat plate 118. The small wheel shaft 453 and the large wheel shaft 454 of one of the transmission members 40 are parallel and spaced apart and are parallel to the X axis. In addition, the small wheel shaft 453 and the large wheel shaft 454 are respectively provided with bearings 46 at both ends; there are 4 bearings 46 in total, of which 2 bearings 46 away from the rotating member 200 are respectively fixed with a pair of bearing mounting holes 1101 of the first vertical plate 111 by their outer rings, and the other 2 bearings 46 are respectively fixed with a pair of bearing mounting holes 1101 of the second vertical plate 112 by their outer rings. The middle axis of the worm 42 is perpendicular to the small wheel shaft 453 and does not intersect; the middle section of the small wheel shaft 453 is coaxially fixed with the worm wheel 43 in the seat gallery 110; the worm 42 and the worm wheel 43 are meshed at the top of the seat gallery 110 near the plane where the X axis and the Z axis intersect.

[0041] Please combine Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 5 is a schematic diagram of the power transmission path and circuit of the self-rotating grill 10; Figure 6It is a sectional view indication diagram of the self-rotating grill 10; Figure 7 and Figure 8 are Figure 6 the sectional structure and the schematic diagram of the partial structure shown.

[0042] In the figure, the outer shell body 31a is fixedly connected to the inclined seat plate 118 through fasteners. Inside the outer shell body 31a is the inner shell body 32a, and a battery compartment 61 is installed in the inner shell body 32a. An installation rack for the heat-resistant motor 50 is integrally formed with the battery compartment 61. The installation rack is generally in the structure of a "Ji"-shaped frame (see Figure 7 the partial structure diagram in the lower right). The top flat plate of the frame of the installation rack is installed with the heat-resistant motor 50 inside the frame through fasteners downward; the top flat plate of the rack is installed with the control package 71 at the top of the "Ji"-shaped frame through fasteners upward, and the control package 71 is surrounded by a heat insulation box body. Setting a heat insulation box body around the control package 71 is beneficial to protecting the control package 71 from the heat released when the heat-resistant motor 50 works. Downward, the two side foot plates of the "Ji"-shaped frame of the installation rack are fixedly connected to the bottom plate of the inner shell body 32a with fasteners. Thus, the heat-resistant motor 50 with the structural rigidity of the rack can output torque without obstacles.

[0043] Please refer to Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 9 is Figure 6 the schematic diagram of the sectional structure of the heat insulation shell 30 component of the self-rotating grill 10 shown along the A-B direction, Figure 10 and is the exploded structure diagram of the heat insulation shell 30 component.

[0044] The heat insulation shell 30 is a bottle-shaped container, including an outer layer shell 31 and an inner layer shell 32. The interlayer between the outer layer shell 31 and the inner layer shell 32 is a hollow structure, and the area inside the hollow structure is in a vacuum or low-vacuum state. By evacuating the interlayer structure into a vacuum or low-vacuum state, the three heat transfer methods can be effectively isolated, so that the key components inside the self-rotating grill 10 in a high-temperature environment can maintain an appropriate temperature, and further enable the whole machine of this application to operate normally for a long time in the relevant equipment during work.

[0045] The outer shell 31 and the inner shell 32 each also include a shell body portion 3a and a shell neck portion 3b; that is, the outer shell 31 is composed of an outer shell body portion 31a and an outer shell neck portion 31b. The inner shell 32 is composed of an inner shell body portion 32a and an inner shell neck portion 32b. The outer shell body portion 31a and the inner shell body portion 32a are cup-shaped containers, and the inner shell body portion 32a is sleeved inside the outer shell body portion 31a. The outer shell neck portion 31b and the inner shell neck portion 32b are tubular bodies, and the inner shell neck portion 32b is sleeved inside the outer shell neck portion 31b. The entire inner shell 32 is sleeved inside the entire outer shell 31. The heat insulation shell 30 can standardize the components in a way of integrating cup-shaped parts and tubular parts into zero and then fit the market supply chain.

[0046] The heat insulation shell 30 further includes a connecting cover 300; the connecting cover 300 includes an outer connecting cover 301, an inner connecting cover 302, and a sealing connecting cover 303. The outer connecting cover 301 is fixedly connected to the outer shell body portion 31a and the outer shell neck portion 31b; the inner connecting cover 302 is fixedly connected to the inner shell body portion 32a and the inner shell neck portion 32b; the sealing connecting cover 303 fixedly connects the outer shell neck portion 31b and the inner shell neck portion 32b at the port of the inner shell neck portion 32b. The purpose of setting the connecting cover 300 is to enable the shell body portion 3a to be designed as an open structure. The advantage is that the shell body portion 3a is an open cavity, that is, an open structure, before being fixedly connected to the connecting cover 300. The open cavity facilitates the entry and installation of components, and thus can simplify the assembly steps of the product. In addition, the connecting cover 300 can also connect the shell body portion 3a and the shell neck portion 3b to play a role of connecting the preceding with the following. Moreover, since the connecting cover 300 is a sheet-like body and is easy to produce and manufacture, it can save the product cost.

[0047] Please continue to combine Figure 9 , Figure 10 , the inner shell neck portion 32b includes three sections of pipes: an upper neck pipe 32b1, a lower neck pipe 32b2, and a broken bridge pipe 32b3. The upper neck pipe 32b1 is connected to the sealing connecting cover 303 at the top and the broken bridge pipe 32b3 at the bottom. So far, starting from the connection between the upper neck pipe 32b1 and the sealing connecting cover 303, from top to bottom are: 1. the upper neck pipe 32b1; 2. the broken bridge pipe 32b3; 3. the lower neck pipe 32b2. The lower neck pipe 32b2 is fixedly connected to the inner shell body portion 32a through the inner connecting cover 302 at its own waist. Above the sealing connecting cover 303 is a flexible heat insulation sleeve 34, and above the flexible heat insulation sleeve 34 is a bearing 46 (see Figure 8)。It can be seen that the contact points between the inner shell 32 of the heat insulation shell 30 and the outside world are only at the fixed connection between the sealing connection cover 303 and the outer shell neck 31b. That is to say, the main path for the high temperature of the environment to enter the inner shell body 32a by conduction is to be transmitted downward through the sealing connection cover 303 to the upper neck tube 32b1, and then the heat transfer path for the upper neck tube 32b1 to transfer heat downward to the inner shell body 32a is the broken bridge tube 32b3. Since the broken bridge tube 32b3 is made of a low thermal conductivity material, in this way, the heat conduction path is blocked by the broken bridge tube 32b3. In addition, from a thermodynamics perspective, although there is a transmission shaft 41 in the space where the inner cavity of the shell neck 3b is connected to the inner cavity of the shell body 3a, the physical phenomenon of heat convection will still occur in the gap between the shaft and the cavity wall. To solve the above problems, the present application provides a flexible heat insulation sleeve 34 between the inner side of the end section of the outer shell neck 31b and the transmission shaft 41, adjacent to the sealing connection cover 303. The flexible heat insulation sleeve 34 can squeeze the transmission shaft 41 inward, squeeze the inner wall of the outer shell neck 31b outward; and squeeze the bearing 46 upward and the sealing connection cover 303 downward, so as to eliminate the gap between the shaft and the cavity wall. With the above functions of the flexible heat insulation sleeve 34, air circulation can be avoided within the range of the inner cavity of the shell neck 3b, and thus, heat convection between the outside world and the inner shell body 32a cannot occur.

[0048] Figure 7 , Figure 8 shows that since the transmission shaft 41 passes through the inside and outside of the inner shell body 32a, there is a potential risk of heat conduction. To solve the above potential risk, the transmission shaft 41 is changed to be composed of a metal section 410 and a non-metal rod section 411. Most of the shaft body of the transmission shaft 41 is arranged in the inner shell neck 32b and penetrates the connection between the inner shell neck 32b and the inner shell body 32a to enter the inner shell body 32a. The arrangement order is: the metal section 410 of the transmission shaft 41 is fixedly connected to the rotating shaft of the heat-resistant motor 50, and the non-metal rod section 411 is fixedly connected to the worm 42. The metal section 410 is made of a material with low cost, low processing difficulty and high toughness, and is very suitable as a joint connecting the rotating shaft of the heat-resistant motor 50. The non-metal rod section 411 is a rod section with low thermal conductivity and has a heat-blocking function, which can block the heat transmitted from outside the heat insulation shell 30.

[0049] Specifically, the non-metallic rod section 411 of the transmission shaft 41 penetrates the inner shell neck 32b. When the self-rotating grill 10 is working, the high-temperature air will cover the entire insulation shell 30. Except for the opening of the shell neck 3b leading to the outside, that is, the bottle mouth of the bottle-shaped container, other parts are protected by the insulation of the vacuum interlayer of the insulation shell 30. The flexible insulation sleeve 34 has blocked the infiltration of air and the heat energy it carries at the above-mentioned bottle mouth. Considering that the non-metallic rod section 411 of the transmission shaft 41 is the only component that penetrates the inner shell neck 32b and the inner shell body 32a and leads to the outside of the insulation shell 30. Let the inner shell neck 32b have enough length, and let the length of the non-metallic rod section 411 be extended accordingly. Combined with the heat-resistant function of the material used for the non-metallic rod section 411, the above measures are equivalent to thickening the insulation material for the weak link of the protection of the inner shell body 32a through the inner shell neck 32b to achieve a good heat-resistant effect. To this end, the method of blocking heat energy from entering the inner shell body 32a and increasing the length of the shell neck 3b and the transmission shaft 41 has a great effect, so that the inner shell body 32a can maintain a suitable temperature to protect the contained components. In addition, no matter how good the heat insulation measures are, it is difficult to prevent heat from seeping in, and a small amount of heat will be generated when the heat-resistant motor 50 is working. The solution is: the heat-resistant motor 50 uses heat-resistant enameled wire 51 as the coil winding, so that the coil winding can withstand relatively high temperature conditions.

[0050] In summary, the heat-insulating shell 30 effectively utilizes structural characteristics and material characteristics to block and resist heat, protect the internal environment, and ensure continuous and normal operation of internal components during use.

[0051] The mechanical principle of this application is as follows:

[0052] Please combine Figure 2 , Figure 5 , Figure 7 , Figure 8 The small wheel shaft 453 is fixedly connected with the worm wheel 43 in the seat gallery 110. The end of the small wheel shaft 453 extending from the seat gallery 110 close to the rotating member 200 is coaxially fixed with the small sprocket 451; the shaft body of the large wheel shaft 454 extending from the seat gallery 110 close to the rotating member 200 is fixedly connected with the large sprocket 452; the large wheel shaft 454 is also connected with the rotating shaft of the rotating member 200. The small sprocket 451 and the large sprocket 452 are coplanar and parallel to the intersection plane of the Y axis and the Z axis. The chain 44 is simultaneously sleeved with the small sprocket 451 and the large sprocket 452, so that the small sprocket 451 and the large sprocket 452 are torsionally linked, and the rotation of one sprocket will cause the two sprockets to rotate synchronously. Thus, the rotating member 200 is indirectly connected to the heat-resistant motor 50 through the transmission member 40 , and the supporting force of the torque transmission of the transmission member 40 is completed by the small wheel shaft 453 , the large wheel shaft 454 in conjunction with a plurality of bearings 46 with the help of the structure of the base 100 .

[0053] The heat-resistant motor 50 is fixedly connected to the metal section 410 of the transmission shaft 41 of one of the transmission members 40 through its own rotating shaft. The other section of the transmission shaft 41, that is, the non-metallic rod section 411, is inserted and installed in the first bearing 46 of the lower neck tube 32b2, and after a certain distance, it is coaxially inserted through another bearing 46 installed on the neck 31b of the housing, and extends out of the heat insulation shell 30 and is fixedly connected to the worm 42. The worm 42 is coaxially fixedly connected to the transmission shaft 41 at the bottom end and is rotatably connected to the third coaxial bearing 46 at the top end. At this time, the rotating shaft of the heat-resistant motor 50, the transmission shaft 41, and the worm 42 are coaxially fixedly connected and rotatably connected to the above three bearings 46. The above-mentioned third bearing 46 is installed on the bearing seat 117. Under the support of the above three bearings 46, the worm 42 can transmit the torque generated by the heat-resistant motor 50 to the worm gear 43 through meshing, completing the first-stage torque transmission and achieving speed reduction.

[0054] After receiving the torque transmitted by the worm 43, the worm gear 43 transmits the torque to the small sprocket 451 through the small wheel shaft 453 fixedly connected to it; the small sprocket 451 drives the large sprocket 452 to rotate through the chain 44, completing the second-stage torque transmission and achieving speed reduction again. Then, the large sprocket 452 transmits the torque to the rotating shaft of the rotating member 200 through the large wheel shaft 454 fixedly connected to it, and finally enables the heat-resistant motor 50 to smoothly drive the rotating member 200 to rotate.

[0055] Specifically, the control principle of this embodiment is as follows:

[0056] Please refer to Figure 5 , Figure 7 , Figure 8 , the control circuit system 70 includes a switch socket 72, a cable 73, and a control package 71. The control package 71 is arranged in the inner shell body 32a of the heat insulation shell 30; the control package 71 is provided with a Bluetooth module 711; the switch socket 72 is arranged in the mounting hole 31b1 on the end section of the neck 31b of the housing. The seat body of the switch socket 72 penetrates the housing and partially exposes outside the housing, and the front of the seat body faces away from the neck 31b of the housing. The switch socket 72 is electrically connected to the control package 71 through the cable 73 led out by its seat body. Specifically, the cable 73 is led out from the seat body of the switch socket 72 in the axial direction of the inner neck 32b and first passes through the flexible heat insulation sleeve 34 in an arc-shaped line. After passing through the bottom of the flexible heat insulation sleeve 34, the cable 73 is laid along the inner wall of the inner neck 32b downward and towards the inner shell body 32a. When approaching the installation position of the bearing 46 on the lower neck tube 32b2, it is bent outward through the avoiding hole 32b22 and enters the cavity of the inner shell body 32a ( Figure 7(in the lower right figure), and then turns downward to pass through the heat insulation box body of the control package 71 and enter the box to be electrically connected to the control package 71. The control package 71 is electrically connected to the battery 60 and the heat-resistant motor 50 through two other cables 73 respectively; the switch socket 72 with a switch is internally provided with a Bluetooth antenna 7111, and the Bluetooth antenna 7111 is electrically connected to the Bluetooth module 711 in the control package 71 through a cable 73 laid on the inner wall of the inner shell neck 32b.

[0057] As Figure 5 , Figure 8 shown, after the power obtained from the external power supply by the jack 722 in the switch socket 72 with a switch of the control circuit system 70 is transmitted to the control package 71 through the cable 73 laid on the inner wall of the inner shell neck 32b, the control package 71 then guides the electric energy to the battery 60 through another cable 73, and the battery 60 receives and stores the electric energy. When the self-rotating grill 10 is loaded with materials and placed in the cooking cavity and is about to bake food, the operator has two ways to start the self-rotating grill 10. The first way: The operator reaches into the cooking cavity of the cooking device 2 and presses the lighted mechanical switch 721 in the switch socket 72 with a switch on the self-rotating grill 10 until the light is on, so as to activate the control circuit system 70. Then press the lighted mechanical switch 721 once again to connect the electrical circuit between the battery 60 and the heat-resistant motor 50. The heat-resistant motor 50 thus obtains electric energy to generate rotation and drives the transmission shaft 41 to rotate through its own rotating shaft, and finally drives the rotating member 200 to rotate. The second way: After activating the control circuit system 70, connect to the Bluetooth through the mobile terminal, and then set instructions such as: power on immediately, power on at a set time, power off at a set time, end reminder, etc. on the screen. Here, taking the example of setting the power-on immediately instruction, after setting the instruction through the mobile terminal, send a message to be received by the Bluetooth antenna 7111 of the self-rotating grill 10. The signal (message) received by the Bluetooth antenna 7111 is transmitted through the cable 73 to the Bluetooth module 711. The Bluetooth module 711 transfers the signal to other subsystems of the control package 71. The circuit of the control package 71 processes the signal and instructs the internal electric switch to turn on the power supply to start the self-rotating grill 10. At this time, the operator closes the door of the cooking device 2 and then presses the start key of the cooking device 2 to perform baking.

[0058] Among them, the function of the scheduled startup setting: First, a default delayed startup time that is used every time can be set permanently. This time can be the action interval when the user moves the self-rotating grill 10 from the food preparation table into the cooking chamber of the cooking device 2, then closes the door, and presses the startup button of the cooking device 2. Setting the default delayed startup time once can be used for a long time, avoiding the situation that because the doors of most cooking devices will shield the signal, the mobile phone will not be able to connect to the inside of the chamber after closing the door, resulting in the operation that cannot be completed in one go, such as putting the food into the chamber first, then going back to get the mobile phone to operate, and then going back to close the door. While the self-rotating grill 10 is still on the table, just click on the mobile phone screen on the table a few times to solve the problem. Second, it can cooperate with the reservation function of some related devices. Third, when encountering cold weather or when the food to be roasted is large raw meat, the cooking device needs to run for a long time to make the cooking chamber have enough heat for effective baking, that is, the so-called warm-up time. During this period, the rotation of the self-rotating grill 10 is doing useless work. If the scheduled startup is set at this time, it is equivalent to starting when it is hot enough, so that the idling can be reduced and the battery power can be saved by 60%.
