[0056] In some embodiments, a rice cooker is disclosed, referring to Figures 1 to 3 The invention comprises a pot body 10, a heating and heat preservation part 11 is arranged in the pot body 10, and a placement cavity for placing the inner pot is formed in the heating and heat preservation part 11. The heating and heat preservation part 11 generally consists of two parts, the upper part is a heat preservation ring, and the lower part is a heating ring. The specific structure of the heating and heat preservation part 11 can refer to the prior art, and will not be described in detail herein.

[0057] The electric rice cooker comprises a cover body 20 , which is rotatably connected to the rice cooker body 10 .

[0058] The pot body 10 includes an outer shell (not shown), and a middle ring 100 is arranged in the outer shell. The structure of the middle ring 100 is as shown in FIG. Figure 5 The middle ring 100 is sleeved on the heating and heat preservation part 11, specifically, the middle ring 100 is sleeved on the outer periphery of the upper heat preservation ring of the heating and heat preservation part 11. The middle ring 100 plays a role in installing and fixing the heating and heat preservation part 11. A table top (not shown) is installed on the top side of the middle ring 100, and the table top serves as the table top of the pot body 10.

[0059] A connecting portion 110 is disposed at the rear end of the middle ring 100 , and the connecting portion 110 is rotatably connected to the cover body 20 to achieve a rotatable connection between the cover body 20 and the pot body 10 .

[0060] Reference Figure 2 and Figure 6 A plurality of wiring grooves are arranged on the connecting portion 110, and the plurality of wiring grooves are isolated from each other. The strong current line and the weak current line of the electric rice cooker are routed through different wiring grooves, so that the strong current and the weak current are isolated.

[0061] The connecting portion 110 not only serves to connect the cover body 20 , but also serves to route wires, and it realizes isolated routing of strong current and weak current through mutually isolated routing grooves.

[0062] In some embodiments, the rice cooker has an automatic water adding function. Figure 1 and Figure 2The electric rice cooker includes a water tank 30, which is used to add water to the inner pot. A water injection port (not shown) is arranged on the cover body 20, and the cover body 20 and the water tank 30 are connected through a water pipeline 720, and a water pump 320 and a flow meter (not shown) are arranged on the water pipeline 720.

[0063] When water needs to be added to the inner tank, the water pump 320 is turned on, and the water in the water tank 30 flows to the water injection port through the water pipe 720 and the water pump 320, and flows into the inner tank through the water injection port.

[0064] In this specific embodiment, the water tank 30 is disposed on the outer side of the pot body 10. Of course, in other embodiments, the water tank 30 may also be disposed at other positions of the pot body 10, such as inside or at the rear of the pot body 10.

[0065] The water pipe 720 extends along the interior of the pot body 10 to the water inlet of the cover body 20. When the water pipe 720 extends inside the pot body 10, since strong and weak currents are also routed inside the pot body 10, in addition to considering the isolation of strong and weak currents, it is also necessary to consider the isolation of the water pipe from strong and weak currents.

[0066] Therefore, a pipe groove is provided on the connection portion 110 , and the pipe groove and the wiring groove are independent of each other. The water pipe 720 in the pot body 10 is routed through the pipe groove and then extends into the cover body 20 .

[0067] In this way, by setting wiring grooves and pipe grooves on the connecting part 110, the high-voltage lines, low-voltage lines and water pipes 720 are independently routed and piped through the corresponding grooves, thereby achieving isolation of high-voltage, low-voltage and water lines, which helps to improve the reliability and safety of the rice cooker.

[0068] In addition, since the connection part 110 is rotatably connected to the cover body 20, the water pipe 720 is routed through the connection part 110, and the pipe routing groove has a limiting effect on the water pipe 720, which helps to improve the smoothness of the water pipe 720 at this location.

[0069] In some embodiments, the rice cooker has a vacuum insulation cooking function. Figure 2 The electric rice cooker includes a vacuum pump 310 and an air pipeline 710. The cover body 20 is provided with an air extraction port (not shown), and the air pipeline 710 is connected between the air extraction port and the vacuum pump 310. When the vacuum pump 310 is started, the gas in the cooking cavity is discharged through the air pipeline 710 and the vacuum pump 310, thereby reducing the pressure in the cooking cavity, helping to reduce the water loss of the food in the cooking cavity and prevent the growth of bacteria, thereby achieving a preservation effect.

[0070] The gas pipeline 710 extends along the interior of the pot body 10 to the air extraction port of the cover body 20. When the gas pipeline 710 extends inside the pot body 10, since strong and weak currents are also routed inside the pot body 10, in addition to considering the isolation of strong and weak currents, it is also necessary to consider the isolation of the gas pipeline from strong and weak currents.

[0071] Therefore, a pipe groove is provided on the connecting portion 110 , and the pipe groove and the wire groove are independent of each other. The gas pipe 710 in the boiler body 10 is routed through the pipe groove and then extends into the cover body 20 .

[0072] In this way, by setting wiring grooves and pipe grooves on the connecting part 110, the high-voltage lines, low-voltage lines and gas pipeline 710 are independently routed and piped through the corresponding grooves, thereby achieving isolation of the high-voltage, low-voltage and gas lines, which helps to improve the reliability and safety of the rice cooker.

[0073] In addition, since the connection part 110 is rotatably connected to the cover body 20, the air pipe 710 is routed through the connection part 110, and the pipe routing groove has a limiting effect on the air pipe 710, which helps to improve the smoothness of the air pipe 710 at this location.

[0074] In some embodiments, the rice cooker has automatic water adding and vacuum cooking functions. The water pipe 720 and the gas pipe 710 extend in the rice cooker body 10 to the cover body 20 .

[0075] A plurality of wiring grooves and a plurality of pipe grooves are arranged on the connection part 110. The high-voltage lines and the low-voltage lines pass through their corresponding wiring grooves, and the water pipes 720 and the gas pipes 710 pass through their corresponding pipe grooves. In this way, the isolation of the high-voltage, low-voltage, gas and water circuits is achieved, thereby improving the reliability and safety of the product.

[0076] In addition, the wiring groove and pipe groove at the connection part 110 play a role in gathering and limiting the lines and pipes of the pot body 10, which helps to improve the regularity of the lines and pipes in the pot body 10, with a compact layout and tidy lines and pipes.

[0077] In some embodiments, reference Figure 2 and Figure 6 There are two wiring troughs, namely a strong current wiring trough 111 and a weak current wiring trough 112. The strong current line is routed through the strong current wiring trough 111, and the weak current line is routed through the weak current wiring trough 112, so as to achieve isolation between strong current and weak current.

[0078] A plurality of pipe grooves are located between the strong current wiring groove 111 and the weak current wiring groove 112. The strong current wiring groove 111 and the weak current wiring groove 112 are located at opposite ends of the connecting portion 110, and the distance between them is large, which further improves the isolation effect of strong current and weak current.

[0079] In some embodiments, there are two pipe grooves, namely, a water pipe groove 113 and a gas pipe groove 114. There is a distance between the water pipe groove 113 and the gas pipe groove 114, and the water pipe 720 is piped through the water pipe groove 113, and the gas pipe 710 is piped through the gas pipe groove 114.

[0080] Specifically, one of the water pipe groove 113 and the gas pipe groove 114 is disposed close to the strong current wiring groove 111 and is located at one end of the connection portion 110; the other is disposed close to the weak current wiring groove 112 and is located at the other end of the connection portion 110. There is a certain distance between the water pipe groove 113 and the gas pipe groove 114, which further improves the isolation effect of the water path and the gas path.

[0081] In some embodiments, reference Figure 6 A plurality of spaced-apart partitions 117 are provided on the connecting portion 110 . The partitions 117 are plate-shaped structures, and a wiring groove or a pipe groove is formed between two adjacent partitions 117 .

[0082] The upper and lower ends of the wiring trough and pipe trough are open to facilitate the extension and passage of wires and pipes.

[0083] In some embodiments, reference Figure 2 , Figure 3 as well as Figure 6 A plurality of reinforcing ribs 115 are provided in the middle area of ​​the connection part 110 to improve the structural strength of the connection part 110. A rotating shaft 610 is provided on the connection part 110, a torsion spring 620 is sleeved on the rotating shaft 610, and the cover body 20 is rotatably connected to the rotating shaft 610.

[0084] The rotating shaft 610 spans across the open sides of the wiring trough and the pipe trough to limit the lines in the wiring trough and the pipes in the pipe trough.

[0085] In order to facilitate the routing of lines and pipes, the wiring trough and pipe trough are open on the side facing outward. If the opening is not blocked, the lines and pipes are prone to friction with the shell. The opening of the wiring trough and pipe trough is blocked by the rotating shaft 610, which plays a role of closing and limiting the lines in the wiring trough and the pipes in the pipe trough, avoiding friction between the lines and pipes and the shell and causing damage, thereby further improving the reliability of the product.

[0086] In some embodiments, reference Figure 3 and Figure 6 A slot 116 is provided on the side wall forming the wiring groove and the side wall forming the pipe groove, and the rotating shaft 610 passes through the slot 116 .

[0087] That is to say, the partition 117 is provided with a slot 116, and when the rotating shaft 610 crosses the connecting portion 110, the rotating shaft 610 passes through the slot 116. In this way, the rotating shaft 610 pushes the lines in the wiring groove and the pipes in the pipe groove further toward the inside of the connecting portion 110, further improving the wiring and pipe routing reliability of the lines and pipes.

[0088] In some embodiments, reference Figure 2 and Figure 3 The connection part 110 is provided with a wiring groove and a pipe groove on a side away from the heating and heat preservation part 11. The controller 500 is provided on the rear side of the middle ring 100, and a gap is formed between the top side of the controller 500 and the bottom side of the connection part 110 for the lines and pipes to pass through.

[0089] The gap between the controller 500 and the connecting portion 110 further serves to limit the lines and pipelines, thereby preventing the lines and pipelines from falling onto the controller 500 .

[0090] In some embodiments, reference Figure 4 A base 200 is disposed in the pot body 10 , and a plurality of first extension portions 210 extending upward are disposed on the base 200 .

[0091] A plurality of second extension portions 120 extending downward are disposed on the middle ring 100 , and the plurality of first extension portions 210 are fixedly connected to the plurality of second extension portions 120 in a one-to-one correspondence.

[0092] Generally, four first extension parts 210 are disposed on the base 200 , and the four first extension parts 210 are disposed at four corners of the base 200 . Correspondingly, four second extension parts 120 are disposed on the middle ring 100 .

[0093] The middle ring 100 and the base 200 are fixed by extension structures at the four corners, which helps to improve the stability of the connection between the middle ring 100 and the base 200. The connection structure occupies a small space, leaving enough installation space for the internal heating and insulation part 11, and also leaving enough installation space for the installation of components such as the controller 500, the vacuum pump 310, and the water pump 320.

[0094] Combination Figure 4 and Figure 8 One of the second extensions 120 located at the rear side of the middle ring 100 is a reinforced extension 130, on which a vacuum pump 310 and / or a water pump 320 are arranged. The reinforced extension 130 is thicker than the other second extensions 120 to improve the structural strength. The reinforced extension 130 is used as a mounting carrier for the vacuum pump 310 and / or the water pump 320, and the structure is compact.

[0095] The vacuum pump 310 and / or the water pump 320 are located in the gap between the reinforcing extension portion 130 and the outer shell of the pot body 10, making full use of the space there and having a compact layout.

[0096] In this specific embodiment, a vacuum pump 310 and a water pump 320 are disposed on the reinforced extension portion 130 , and the vacuum pump 310 and the water pump 320 are arranged in sequence along the height direction of the reinforced extension portion 130 .

[0097] Reference Figure 2 The water tank 30 is disposed on the outer side of the pot body 10, and the water pump 320 is disposed on a side close to the water tank 30, which helps to reduce the length of the water pipe 720 and facilitates pipe routing.

[0098] In some embodiments, reference Figure 7 A plurality of spaced-apart partitions 131 are disposed on the reinforcing extension portion 130 . The partitions 131 extend along a height direction of the reinforcing extension portion 130 . A first arc-shaped portion 132 is disposed on the partitions 131 .

[0099] In this specific embodiment, three spaced-apart partitions 131 are provided on the reinforcing extension portion 130 , two first arc-shaped portions 132 are provided on each partition 131 , and the first arc-shaped portions 132 on two adjacent partitions 131 correspond to each other in the horizontal direction.

[0100] Combination Figure 8 and Fig. 9 A vibration-damping sleeve 410 is mounted on the vacuum pump 310 and / or the water pump 320 , and the vibration-damping sleeve 410 is fixed to the reinforced extension portion 130 through a mounting plate 420 . The vacuum pump 310 and / or the water pump 320 spans the reinforced extension portion 130 and is partially embedded in the corresponding first arc portion 132 .

[0101] The mounting plate 420 is fixed to the gap between two adjacent partitions 131 by screws, and the vibration-damping sleeve 410 is just embedded in the gap between the two adjacent partitions 131. On the one hand, the main body of the vacuum pump 310 and / or the water pump 320 is embedded in the corresponding first arc-shaped portion 132 to play a limiting role; on the other hand, the vibration-damping sleeve 410 helps to reduce the working vibration noise of the pump; in addition, the vibration-damping sleeve 410 is embedded in the gap between the two adjacent partitions 131, which further plays a role in the installation of the pump, and fully utilizes the gap space, with a compact structure.
