Split cookers, as a new type of kitchen utensil, are gradually favored by consumers because of their easy cleaning, storage and use. For example, a split electric hot pot disclosed in Chinese patent CN2624760Y includes a pot body and a base, and an electric heating plate is arranged on the base, and the pot body is placed on the electric heating plate. When in use, the pot body is fixed on the base, and can be easily separated from the base for cleaning after use. However, the above split electric hot pot has at least the following defects: First, when the soup in the pot body overflows during cooking and drips onto the electric heating plate, it may cause a short circuit in the circuit and even cause a fire, and the salt, grease and other components in the soup may corrode and oxidize the electric heating plate, reducing the service life of the electric heating plate. Second, the split electric hot pot is lacking in the control of the overflow transmission of the base temperature and the prevention and control of abnormal high temperature, resulting in many high temperature accidents and easy fire. Third, the split-type electric hot pot has a single function and cannot meet the needs of users for different cooking methods. Summary of the invention

[0003] One of the technical problems that the present invention aims to solve is to enrich the cooking functions of the cooker while optimizing its electrical safety. The present invention proposes a split cooker, comprising a pot base and a pot that can be used separately from each other, the pot can be placed on the pot base to be heated; the bottom of the pot is stepped and includes a first pot bottom surface and a second pot bottom surface configured at different heights; it is characterized in that a top ring portion is arranged on the top of the pot base, the upper surface of the top ring portion has a horizontally extending support surface, and also includes a heat insulation cover and a heating plate, the heat insulation cover is basin-shaped and includes a basin bottom wall and a basin side wall, the heat insulation cover is open upward, the heating plate is placed in the heat insulation cover, the outer diameter of the heating plate is not only smaller than the inner diameter of the ring opening of the top ring portion but also smaller than the inner diameter of the basin side wall; the upper surface of the heating plate is shorter than the support surface of the top ring portion; when the pot is placed on the pot base, the second pot bottom surface sinks into the ring opening of the top ring portion and fits and supports on the upper surface of the heating plate, the first pot bottom surface is The surface is located above the support surface, and the outer diameter of the outer wall of the pot is equal to the outer diameter of the top ring; the heating plate has a central hole, and a first temperature sensor that can float up and down is arranged in the central hole, and when the pot is placed on the pot base, the first temperature sensor is attached to the second pot bottom surface; the lower part of the heating plate is provided with supporting legs, and the heating plate is supported on the basin bottom wall of the heat insulation cover by the supporting legs; a second temperature sensor and a temperature fuse are attached to the lower side surface of the basin bottom wall of the heat insulation cover, wherein the second temperature sensor contacts the abutting position where the supporting legs abut against the heat insulation cover, and the temperature fuse is relatively far away from the abutting position; the temperature fuse is connected in series in the primary circuit that supplies power to the heating plate, and is used to sense that when abnormally high temperature occurs on the heat insulation cover, it can be heated and automatically melted, thereby disconnecting the primary circuit that supplies power to the heating plate; It also includes a central controller, the central controller signal is connected to the first temperature sensor and the second temperature sensor, the first temperature sensor is used to feed back the temperature signal of the second pot bottom surface to the central controller, and the second temperature sensor is used to feed back the temperature signal of the abutment position to the central controller; it also includes a human-machine dialogue device, the human-machine dialogue device signal is connected to the central controller, the human-machine dialogue device is used to receive cooking instructions and send corresponding work instructions to the central controller, the central controller is used to control the power supply to the heating plate according to the work instruction and the temperature signal provided by the first temperature sensor, and the central controller is also used to control the heating plate to stop working when the temperature signal fed back by the second temperature sensor reaches a set value.

[0004] According to the above technical solution, compared with the prior art, the beneficial technical effects of the present invention are: first, because the outer diameter of the outer wall of the pot is equal to the outer diameter of the top ring, when the soup in the pot overflows during cooking, most of the soup crawls along the outer wall of the pot to the outer surface of the top ring and drips onto the ground, thereby reducing the amount of soup crawling onto the support surface and then dripping onto the heat insulation cover and the heating plate. Second, the central controller is used to control the power supply of the heating plate according to the working instruction and the temperature signal provided by the first temperature sensor. In this way, under the control of the central controller, the heating plate has a heating mode that meets different cooking modes, which greatly enriches the diversity of the cooking functions of the split cooker. At the same time, under the temperature detection of the first temperature sensor, it can also prevent the temperature of the heating plate from being too high and causing safety accidents. The first temperature sensor constitutes the first layer of high temperature protection. Third, the pot base is also equipped with a second temperature sensor and a temperature fuse. When an abnormality occurs, such as the failure of the first temperature sensor to cause the heating plate to heat out of control, when the temperature signal fed back by the second temperature sensor to the central controller reaches the set value, the central controller controls the heating plate to stop working, and the second temperature sensor becomes the second layer of high temperature protection; and when the second temperature sensor fails to function, the temperature fuse senses the abnormally high temperature on the heat insulation cover and can be heated and melted automatically, disconnecting the primary circuit, forming the third layer of high temperature protection. It can be seen that the split cooker not only has rich cooking functions, but also has excellent electrical safety.

[0013] The structure of the split cooker using the technical solution of the present invention is further described below in conjunction with the accompanying drawings. Except for the embodiments that are explicitly described as equivalent or optional, the various implementation details disclosed below can be selectively applied or combined in one embodiment even if they are not directly related or coordinated in terms of function.

[0014] like Figures 1 to 4The figure shows a split cooker, comprising a pot base 100 and a pot 200 which can be separated from each other for use, wherein the pot 200 can be placed on the pot base 100 for heating; the bottom of the pot 200 is stepped and comprises a first pot bottom surface 201 and a second pot bottom surface 202 arranged in a high and low manner; a top ring portion 1 is arranged on the top of the pot base 100, wherein the upper surface of the top ring portion 1 has a horizontally extending support surface 10, and further comprises a heat insulation cover 2 and a heating plate 3, wherein the heat insulation cover 2 is basin-shaped and comprises a basin bottom wall 21 and a basin side wall 22, wherein the heat insulation cover 2 is open upward, and the heating plate 3 is placed in the heat insulation cover 2, wherein the outer diameter of the heating plate 3 is not only smaller than the inner diameter of the ring opening of the top ring portion 1 but also smaller than the basin side wall 22. The inner diameter of the heating plate 3; the upper surface of the heating plate 3 is shorter than the supporting surface 10 of the top ring part 1; when the pot 200 is placed on the pot base 100, the second pot bottom surface 202 sinks into the ring mouth of the top ring part 1 and fits and supports on the upper surface of the heating plate 3, the first pot bottom surface 201 is located above the supporting surface 10, and the outer diameter of the outer wall of the pot 200 is the same as the outer diameter of the top ring part 1; the heating plate 3 has a central hole 30, and a first temperature sensor 41 that can float up and down is arranged in the central hole 30. When the pot 200 is placed on the pot base 100, the first temperature sensor 41 is attached to the second pot bottom surface 202; the lower part of the heating plate 3 is provided with Support legs (not shown), the heating plate 3 is supported on the basin bottom wall 21 of the heat insulation cover 2 by the support legs; a second temperature sensor 42 and a temperature fuse 4 are provided on the lower side of the basin bottom wall 21 of the heat insulation cover 2, wherein the second temperature sensor 42 contacts the abutting position where the support legs abut against the heat insulation cover 2, and the temperature fuse 4 is relatively far away from the abutting position; the temperature fuse 4 is connected in series in the primary circuit for supplying power to the heating plate 3, and is used to sense that when abnormally high temperature occurs on the heat insulation cover 2, it can be heated and automatically melted, thereby disconnecting the primary circuit for supplying power to the heating plate 3; and a central controller is also included, and the central controller signal is connected to the first temperature sensor 41, the second temperature sensor 4 2, the first temperature sensor 41 is used to feed back the temperature signal of the second pot bottom surface 202 to the central controller, and the second temperature sensor 42 is used to feed back the temperature signal of the abutment position to the central controller; it also includes a human-machine dialogue device 50, the human-machine dialogue device 50 signal is connected to the central controller, the human-machine dialogue device 50 is used to receive cooking instructions and send corresponding work instructions to the central controller, the central controller is used to control the power supply of the heating plate 3 according to the work instruction and the temperature signal provided by the first temperature sensor 41, and the central controller is also used to control the heating plate 3 to stop working when the temperature signal fed back by the second temperature sensor 42 reaches a set value.

[0015] The pot base 100 and the pot 200 are two independent modules that can be separated from each other for use. The pot base 100 integrates various electrical components, such as the heating plate 3, the central controller, and the fan and control circuit board 60 to be discussed below.

[0016] The pot 200 is mainly used for holding food and can be separated from the pot base 100 for easy cleaning. The pot 200 includes an annular pot side wall 203 and a pot bottom that closes the bottom of the pot side wall 203. The first pot bottom surface 201 and the second pot bottom surface 202 are two bottom surfaces with a height difference. In this embodiment, the second pot bottom surface 202 is located in the middle of the bottom of the pot 200, and the first pot bottom surface 201 is located at the periphery of the second pot bottom surface 202. When the pot 200 is placed on the pot base 100, the second pot bottom surface 202 sinks into the ring opening of the top ring part 1 and fits and supports on the upper surface of the heating plate 3, and the first pot bottom surface 201 is located above the support surface 10. In this way, the pot 200 is radially positioned by the concave-convex fit between the second pot bottom surface 202 and the top ring part 1, which increases the difficulty of the pot 200 sliding off the pot base 100 when subjected to lateral thrust. The first pot bottom surface 201 is located above the support surface 10, which can be understood as the first pot bottom surface 201 being arranged above the support surface 10 with a suspended interval, so that the matching accuracy between the bottom of the pot 200 and the top ring 1 can be reduced, and the first pot bottom surface 201 will not hinder the second pot bottom surface 202 from being supported on the upper surface of the heating plate 3 due to being supported on the support surface 10. Of course, if the accuracy requirements are met, it is also possible for the first pot bottom surface 201 to be supported on the support surface 10.

[0017] The outer diameter of the heating plate 3 is smaller than the inner diameter of the ring opening of the top ring portion 1 , so that the amount of heat radiation transferred from the heating plate 3 to the top ring portion 1 can be reduced.

[0018] The outer diameter of the outer wall of the pot 200 is equal to the outer diameter of the top ring 1. In practical applications, the outer diameter of the outer wall of the pot 200 and the outer diameter of the top ring 1 do not have to be equal, and their radii can have a tolerance within ±3 mm. In this way, when the soup in the pot 200 overflows during cooking, most of the soup crawls along the outer wall of the pot 200 to the outer surface of the top ring 1 and drips onto the ground, thereby reducing the amount of soup that crawls onto the support surface 10 and then drips onto the heat insulation cover 2 and the heating plate 3.

[0019] The heating plate 3 is supported on the basin bottom wall 21 of the heat insulation cover 2 through the supporting legs, so that the heat conducted from the heating plate 3 to the heat insulation cover 2 can be reduced.

[0020] The layout position of the central controller is various, for example, it can be set on the human-machine dialogue device 50 or on the control circuit board 60 to be discussed below.

[0021] The first temperature sensor 41 includes a mounting cap 410, a temperature sensing element (not shown in the figure, for example, it can be a thermistor), a first clamp 411, and a second clamp 412. The first clamp 411 is provided with a laterally extending elastic arm 4111 and a vertically extending first vertical arm 4112, and the second clamp 412 is provided with a laterally extending support plate 4121 and a vertically extending second vertical arm 4122. The elastic arm 4111 is arranged above the support plate 4121 and they both extend into the mounting cap 410. The elastic arm 4111 presses the temperature sensing element tightly against the inner top wall of the mounting cap 410. The first vertical arm 4112 is located on the outer side of the second vertical arm 4122 and forms a line channel therebetween. The signal line connecting the temperature sensing element is arranged in the line channel. A mounting through hole 20 is provided in the middle of the basin bottom wall 21 of the heat shield 2, and a mounting seat 414 is arranged below the hole peripheral wall of the mounting through hole 20. The connecting piece 4145 of the mounting seat 414 passes through the hole peripheral wall of the mounting through hole 20 and is bent to connect the mounting seat 414 to the lower side of the basin bottom wall 21. The vertical bar 4141 on the mounting seat 414 passes through the mounting through hole 20 and extends above the basin bottom wall 21. The mounting cap 410 is arranged above the basin bottom wall 21 and is slidably connected to the vertical bar 4141 through the cap ear 4101. A cutting strip 4142 is provided at the top of the vertical bar 4141, and the cutting strip 4142 is bent and placed on the cap ear 4101. The spring 413 is pressed between the second clamp 412 and the mounting seat 414 to enable the first temperature sensor 41 to float up and down. The upper flange 4144 of the mounting seat 414 is bent to fix the spring 413 .

[0022] The human-machine dialogue device 50 is a device that allows the user to communicate and operate with the central controller, such as a control panel set on the pot base 100, an APP installed on a mobile phone, etc. The user inputs cooking instructions through the human-machine dialogue device 50, and the human-machine dialogue device 50 receives the cooking instructions and sends corresponding work instructions to the central controller. The central controller is used to control the power supply of the heating plate 3 according to the work instructions and the temperature signal provided by the first temperature sensor 41, wherein the "power supply control" includes controlling the power size of the heating plate 3, the continuous working time, the frequency of intermittent working, etc., so that the heating plate 3 has a heating mode that meets different cooking modes.

[0023] The second temperature sensor 42 may be a temperature sensing element such as a thermistor. When an abnormality occurs, such as the failure of the first temperature sensor 41, which causes the heating of the heating plate 3 to be out of control, and the temperature of the abutting position where the support leg abuts the heat shield 2 reaches a set value, such as 280° (the set value is lower than the fuse temperature of the temperature fuse 4), the central controller controls the heating plate 3 to stop working in response to the temperature signal reaching the set value fed back by the second temperature sensor 42. The second temperature sensor 42 is not damaged, and the heating plate 3 can still be started to work after the temperature drops to a safe value.

[0024] Wherein, the fusing temperature of the temperature fuse 4 is higher than the above-mentioned set value, for example, it is set to about 400°. When an abnormality occurs, for example, the pot 200 is deformed, or there is a foreign object on the heating plate 3, resulting in a large gap between the pot 200 and the heating plate 3, a large amount of heat of the heating plate 3 cannot be transmitted to the pot 200 in time and is radiated to the heat insulation cover 2 in large quantities, and the temperature of the heat insulation cover 2 continues to rise, and the second temperature sensor 42 has a temperature sensing delay phenomenon or other functional defects and fails. When an abnormally high temperature occurs, for example, higher than 400°, the temperature fuse 4 automatically fuses, disconnects the primary circuit, and the heating plate 3 is powered off and stops working. Later, the temperature fuse 4 needs to be replaced to repair the pot base 100. Wherein, the working voltage of the primary circuit is the mains voltage. In this embodiment, the heating plate 3 is electrically connected through the control circuit board 60, and the on-off switch of the primary circuit is set on the control circuit board 60, and the central controller controls the on-off switch of the primary circuit. The temperature fuse 4 is connected in series to the live wire of the power line in front of the control circuit board 60. As can be seen from the above, the first temperature sensor 41 constitutes the first layer of high temperature protection, the second temperature sensor 42 constitutes the second layer of high temperature protection, and the temperature fuse 4 constitutes the third layer of high temperature protection.

[0025] The bottom wall 21 of the heat shield 2 is provided with a fuse groove and a slot 210 which are recessed upwards, and the temperature fuse 4 is placed on the fuse groove. A pressing piece 43 is also included to press the temperature fuse 4 tightly against the fuse groove, one end of the pressing piece 43 is inserted into the slot 210 and bent and overlapped on the upper side of the bottom wall 21, and the other end is locked on the bottom wall 21 of the heat shield 2 by a screw 44.

[0026] like Figure 1As shown, in order to enhance the safety of the pot base 100, a position sensor 8 is further provided on the top ring part 1, and the position sensor 8 is connected to the central controller. The position sensor 8 is used to sense the signal that the pot 200 leaves the pot base 100 and provide the leaving signal to the central controller, and the central controller is used to disconnect the primary circuit that supplies power to the heating plate 3 according to the received leaving signal. The position sensor 8 can be a micro switch.

[0027] like Figure 1 and Figure 5 As shown, the pot base 100 also includes a chassis 7 and a cylindrical side wall portion 5, a connecting rod 11 is arranged on the lower side of the top ring portion 1, the top ring portion 1 and the connecting rod 11 are integrally formed, and the human-machine dialogue device 50 is arranged on the side wall portion 5; the side wall portion 5 is arranged between the top ring portion 1 and the chassis 7, and the connecting rod 11 is located on the inner side of the side wall portion 5 and close to the side wall portion 5, the screw passes through the chassis 7 and is connected to the connecting rod 11, so as to tighten and connect the top ring portion 1, the side wall portion 5 and the chassis 7; several connecting rods 11 are evenly arranged, the basin bottom wall 21 and the basin side wall 22 of the heat insulation cover 2 are arranged in the central space defined by several connecting rods 11, the basin side wall 22 of the heat insulation cover 2 is provided with an outwardly bent outer flange, and a protruding connecting ear 221 is provided on the outer flange, and the outer flange of the heat insulation cover 2 is connected to the connecting rod 11 through the connecting ear 221. In this way, on the one hand, the connecting rod 11 not only plays the role of an intermediate transition connection in tightening the connection between the top ring portion 1, the side wall portion 5 and the bottom plate 7, but also transfers the weight of the heat insulation cover 2 and the heating plate 3 placed in the heat insulation cover 2 to the bottom plate 7, and the connecting rod 11 plays the role of supporting the heat insulation cover 2; on the other hand, the heat insulation cover 2 is suspended on the connecting rod 11, which greatly reduces the heat conducted from the heat insulation cover 2 to the bottom plate 7 and the side wall portion 5.

[0028] There are many ways to connect the connecting ear 221 to the connecting rod 11, for example, the connecting ear 221 is locked to the connecting rod 11 by screws. In this embodiment, the following screw-on structure is adopted: the connecting ear 221 extends in the horizontal direction, and a horizontal groove 110 capable of accommodating the connecting ear 221 is provided at the position where the top ring part 1 is connected to the connecting rod 11 or on the connecting rod 11, and the connecting ear 221 is connected to the connecting rod 11 by being screwed into the horizontal groove 110 in the horizontal direction; a protruding positioning ear 222 is provided on the outer flange, and when the connecting ear 221 is screwed into the horizontal groove 110, the positioning ear 222 is bent and overlapped to the lower side of the top ring part 1 to achieve the positioning of the heat shield 2. This greatly simplifies the installation operation of the heat shield 2. Further, two blocking sheets 12 arranged at intervals on the left and right are provided on the lower side of the top ring part 1, and the positioning ear 222 is bent and overlapped between the two blocking sheets 12.

[0029] Furthermore, the inner diameter of the basin side wall 22 of the heat insulation cover 2 is smaller than the inner diameter of the ring opening of the top ring part 1, and the outer flange extends to the bottom of the top ring part 1; and a heat insulation sheet 9 is also included, one end of which is arranged between the outer flange and the top ring part 1, and the other end extends into the ring opening of the top ring part 1. In this way, the heat conducted from the heat insulation cover 2 and the pot 200 to the top ring part 1 can be reduced. The heat insulation sheet 9 can be a silicone sheet.

[0030] like Figure 5 and Figure 6As shown, the chassis 7 is provided with heat dissipation holes 70, and a fan (not shown) and a control circuit board 60 are provided in the space between the heat shield 2 and the chassis 7 (also the central space mentioned above). The fan is fixed on the chassis 7 and connected to the control circuit board 60 by signal. The first temperature sensor 41, the second temperature sensor 42, and the central controller are respectively connected to the control circuit board 60 by signal. The first temperature sensor 41 and the second temperature sensor 42 are respectively connected to the central controller by signal through the control circuit board 60. The box body 6 for accommodating and connecting the control circuit board 60 is also included. The box body 6 is arranged with the opening facing downward, and the left and right sides of the box body 6 are respectively provided with box ears 61; the chassis 7 is provided with a positioning column 71 extending upward and corresponding to the connecting rod 11, and the box ear 61 is clamped between the connecting rod 11 and the positioning column 71, and the screw passes through the chassis 7, the positioning column 71, and the box ear 61 to connect the connecting rod 11. In this way, while the top ring part 1, the side wall part 5 and the bottom plate 7 are tightened and connected, the box body 6 can also be fixed by means of the connecting rod 11 and the positioning column 71. In addition, a drain port 211 is provided on the basin bottom wall 21 of the heat insulation cover 2. When viewed from top to bottom, the drain port 211 is staggered with the box body 6 and the fan. A winding drum (not shown) is also fixedly connected to the bottom plate 7, and the power cord is wound and stored on the winding drum.

[0031] Furthermore, a notch 62 and a semi-circular guard bar 63 are provided on the side wall of the box body 6. One end of the guard bar 63 is connected to the left peripheral wall of the notch 62, and the other end is connected to the right peripheral wall of the notch 62. The guard bar 63 is used to bind the signal line. In this way, part of the signal line connected to the control circuit board 60 and the electrical components located outside the box body 6, such as the first temperature sensor 41 and the second temperature sensor 42, can be selected to go around the guard bar 63 and pass through the notch 62. The activity range of the signal line is limited by the guard bar 63 and the top wall 621 of the notch 62. Part of the signal line that does not need to be connected to the control circuit board 60 can also be tied to the guard bar 63 by a binding wire.

[0032] like Figure 7As shown, in order to fix the signal line, a wire clamping mechanism for binding the signal line can be provided on at least one of the connecting rods 11, and the wire clamping mechanism includes an upwardly extending clamping arm 110, the lower end of the clamping arm 110 is fixed on the connecting rod 11, and the upper end is a free end, and a wire clamping groove 112 with a notch facing upward is formed between the clamping arm 110 and the connecting rod 11, and a protrusion 111 for narrowing the notch of the wire clamping groove 112 is provided on the upper end of the clamping arm 110. Further, an inclined guide surface 113 located above the opening of the wire clamping groove 112 is provided on the connecting rod 11, and the inclined guide surface 113 is used to guide the signal line to move toward the wire clamping groove 112. In this way, the signal line can pass through the notch and enter the wire clamping groove 112 under the guidance of the inclined guide surface 113, and the provision of the protrusion 111 increases the difficulty of the signal line passing through the notch and escaping from the wire clamping groove 112.
