[0001] The invention relates to a cooking utensil, and in particular to an improvement of a pot body of the cooking utensil. Background Art

[0002] At present, the electric pressure cookers in the prior art are prone to overflow during exhaust, so exhaust is performed in an intermittent manner. The above exhaust method takes a relatively long time and cannot achieve rapid pressure reduction and lid opening. In order to quickly reduce the pressure inside the electric pressure cooker and achieve rapid lid opening, a cooling chamber is generally provided in the electric pressure cooker to quickly reduce the temperature of the inner pot or the lid. As the temperature of the inner pot or the lid drops rapidly, the pressure in the inner pot also drops rapidly, thereby achieving rapid lid opening and improving user experience. In the above-mentioned electric pressure cooker with a rapid lid opening function, a water tank and a water pump are generally provided, and the coolant can circulate between the water tank and the cooling chamber through the water pump. The water tank is detachably arranged on the electric pressure cooker. In order to position the water tank, a limited position structure is generally provided. In order to fix the water pump, a mounting column is generally provided on the electric pressure cooker. The above structure is not only complex in structure, but also occupies a large space, making the product volume of the electric pressure cooker larger and reducing the aesthetics of the electric pressure cooker. Summary of the invention

[0003] The main purpose of the present invention is to provide a cooking utensil to solve the problem of large volume of the cooking utensil in the prior art.

DETAILED DESCRIPTION

[0049] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0050] like Figures 1 to 5As shown, the cooking utensil of this embodiment includes a pot body 10, a first workpiece and a second workpiece. Among them, a receiving groove 111 is provided on the outer wall of the pot body 10, and a first protrusion structure 112 extending toward the inside of the receiving groove 111 is provided on the groove wall of the receiving groove 111. The first workpiece is received in the receiving groove 111, and the first workpiece can be removed from the receiving groove 111 by disassembling the first workpiece along the front-back direction of the pot body 10. The first workpiece is provided with a first matching structure 251 that matches with the first protrusion structure 112 to position the first workpiece. The second workpiece is located in the pot body 10, and the second workpiece is fixed to the first protrusion structure 112 by a connecting member.

[0051] By applying the technical solution of this embodiment, the first protruding structure 112 can both position the first workpiece and fix the second workpiece, avoiding the need to provide mounting components for the second workpiece. This reduces production costs on the one hand, and reduces occupied space on the other hand, thereby reducing the size of the cooking utensil, making the appearance of the cooking utensil more beautiful and solving the problem of the large size of the cooking utensil in the prior art.

[0052] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, the first matching structure 251 is a first concave structure that matches with the first convex structure 112. When the first workpiece moves along the left and right directions of the pot body 10, the inner wall of the first concave structure on the first workpiece will abut against the first convex structure 112 to limit the first concave structure. Since the first concave structure is arranged on the first workpiece, the first workpiece is also limited. In addition, the matching of the above-mentioned convex structure and the concave structure is simple and easy to process.

[0053] like Figure 1 and Figure 5 As shown, in this embodiment, the groove wall of the accommodating groove 111 includes a groove top wall 1111, a groove bottom wall 1112 and a connecting side wall 1113 connecting the groove top wall 1111 and the groove bottom wall 1112, and the first protruding structure 112 is arranged on the groove bottom wall 1112. The above structure is simple and easy to process. Of course, those skilled in the art should know that the first protruding structure 112 can also be arranged on the connecting side wall 1113 according to actual conditions (the actual setting position of the second workpiece).

[0054] like Figure 1 and Figure 5As shown, in this embodiment, the first protruding structure 112 is located at the connection between the bottom wall 1112 of the groove and the connecting side wall 1113. When the user takes the water tank, the first workpiece can be removed by directly applying a forward force to the first workpiece. Therefore, the above structure facilitates the user to take the first workpiece, thereby improving the user's experience. Of course, those skilled in the art should know that the setting position of the first protruding structure 112 is not limited to the connection between the bottom wall 1112 of the groove and the connecting side wall 1113, and can also be set in the middle of the bottom wall 1112 of the groove. When the first protruding structure 112 is set in the middle of the bottom wall 1112 of the groove, the first concave structure on the first workpiece corresponds to the mounting hole, and when the first workpiece is installed in the accommodating groove 111, the first protruding structure 112 extends into the mounting hole. When the user takes the first workpiece, it is necessary to first move the first workpiece upward to make the first protruding structure 112 come out of the mounting hole. Then a forward force is applied to the first workpiece to remove the first workpiece.

[0055] like Figure 4 As shown, in this embodiment, the pot body 10 includes an outer shell 11 and an inner pot 12 located in the outer shell 11. The inner pot 12 is used to hold food to be cooked. A cooling chamber 1 is provided between the outer shell 11 and the inner pot 12 to reduce the temperature of the inner pot 12. The receiving groove 111 is provided on the outer wall of the outer shell 11. In the above structure, since the cooling chamber 1 can quickly reduce the temperature of the inner pot 12, the pressure in the inner pot 12 also drops rapidly, thereby realizing quick opening of the lid and improving the user experience. Since the first workpiece is a component that the user needs to take frequently, the receiving groove 111 for accommodating it is provided on the outer wall of the outer shell, so as to facilitate the user to take it.

[0056] Since the coolant in the cooling chamber 4 contacts the inner pot 12 with a higher temperature, the temperature of the coolant will rise rapidly. Since the temperature of the coolant is high, the heat absorption capacity of the coolant will decrease, and the heat absorption efficiency will be low. In order to further increase the opening speed. Figure 1 As shown, in this embodiment, the first workpiece is a water tank 20, the second workpiece is a water pump 30, and the coolant circulates between the water tank 20 and the cooling chamber 1 through the water pump 30. The above structure enables the coolant in the cooling chamber 1 to maintain a relatively low temperature, thereby ensuring the heat absorption capacity of the coolant, improving the heat absorption efficiency, and thus realizing an increase in the opening speed.

[0057] like Figure 1 and Figure 2 As shown, in this embodiment, the first matching structure 251 is disposed on the water tank bottom wall 25 of the water tank 20. The above structure is simple and easy to assemble.

[0058] like Figure 4 and Figure 5As shown, in this embodiment, the lower part of the first protruding structure 112 is provided with a first mounting hole 113 extending upward, and the connecting member is a screw. After the screw penetrates the second workpiece, it cooperates with the first mounting hole 113 to fix the second workpiece on the first protruding structure 112. Specifically, in this embodiment, the second workpiece is a water pump 30, and the water pump 30 has a mounting frame, and the mounting frame is provided with a mounting hole. During installation, the mounting hole on the mounting frame is set corresponding to the first mounting hole 113, and then the screw is penetrated from bottom to top into the mounting hole on the mounting frame and the first mounting hole 113. The above installation method is simple and easy to assemble.

[0059] like Figure 1 As shown, in this embodiment, there are two first protrusion structures 112 arranged at intervals, and the two first protrusion structures 112 are arranged along the front-rear direction perpendicular to the pot body 10. The above structure makes the positioning effect of the water tank 20 better on the one hand. On the other hand, it can fix two water pumps 30 correspondingly, thereby improving the space utilization.

[0060] like Figure 4 , Figures 7 to 11 As shown, in this embodiment, the pot body 10 also includes a heating device 13, which is located between the outer shell 11 and the inner pot 12. A cooling chamber 1 is formed between the inner pot 12 and the heating device 13 to reduce the temperature of the inner pot 12. A temperature sensing device 133 is provided at the bottom 132 of the heating device 13, and a drainage groove 1321 is provided on the circumferential outer side of the temperature sensing device 133. The drainage groove 1321 has a low point L, and a coolant outlet 134 is provided in the drainage groove 1321, wherein the coolant outlet 134 is located at the low point L.

[0061] By applying the technical solution of this embodiment, when there is more coolant in the cooling cavity 1, the coolant can flow out directly from the coolant outlet 134. When there is less coolant in the cooling cavity 1, the above structure allows the coolant in the cooling cavity 1 to enter the lower drainage groove 1321, then flow to the low point L of the drainage groove 1321, and finally flow out from the coolant outlet at the low point L. The above structure can greatly reduce the amount of coolant remaining in the cooling cavity 1, thereby reducing the degree of corrosion of the cavity wall of the cooling cavity 1 by the residual liquid, and ultimately ensure the service life of the cooking utensil, solving the problem of short service life of the cooking utensil in the prior art.

[0062] like Figure 8 and Fig. 9 As shown, in this embodiment, the drainage groove 1321 also has a high point H. The above structure allows the coolant entering the drainage groove 1321 to flow from the high point H to the low point L under the action of its own gravity, and finally flows out from the coolant outlet 134. The above structure can further reduce the residual amount of coolant remaining in the cooling chamber 1.

[0063] like Figures 8 to 10 As shown, in this embodiment, the drainage groove 1321 is annular, and the curve Z formed by the lowest points of the drainage groove 1321 at various positions in the circumferential direction is located in the same inclined plane. The above-mentioned inclined structure can guide the coolant, and the coolant can gradually flow to the low point L along the drainage groove 1321 (inclined surface), that is, no matter where the coolant is at a position higher than the low point L, it has a tendency to flow toward the low point L, thereby minimizing the amount of coolant remaining in the cooling chamber 1. Fig.10 G is the height difference between the high point H and the low point L.

[0064] In other embodiments, the outer edge and / or inner edge of the cross section of the drainage groove 1321 is polygonal or elliptical. The above structure is simple and easy to process.

[0065] like Figure 7 , Figure 8 and Fig.11 As shown, in this embodiment, a filter device 135 is provided at the coolant outlet 134. The above structure can preliminarily filter the impurities contained in the coolant to prevent these impurities from entering the water pump 30, thereby ensuring the service life of the water pump 30.

[0066] like Figure 7 , Figure 8 and Fig.11 As shown, in this embodiment, the filter device 135 is a filter screen. The above structure is simple and easy to process and assemble. Of course, those skilled in the art should know that the filter device is not limited to a filter screen and can also be a filter block composed of multiple filter layers.

[0067] like Figures 7 to 10 As shown, in this embodiment, a mounting hole for mounting a temperature sensing device 133 is provided in the middle of the bottom 132 , and the temperature sensing device 133 passes through the mounting hole from bottom to top and extends into the heating device 13 to measure the temperature of the inner pot 12 .

[0068] like Fig.10 As shown, in this embodiment, the temperature sensing device 133 includes a temperature sensing device body 1331 and a temperature sensing device sealing ring 1332 sleeved on the temperature sensing device body 1331. The temperature sensing device sealing ring 1332 is sleeved on the temperature sensing device body 1331 extending into the heating device 13 and seals the gap between the hole wall of the mounting hole and the temperature sensing device body 1331. The above structure can seal the gap between the hole wall of the mounting hole and the temperature sensing device body 1331 to prevent the coolant in the cooling chamber 1 from entering the temperature sensing device 133, thereby ensuring the service life of the temperature sensing device 133.

[0069] like Figures 12 to 19As shown, in this embodiment, the cooking appliance further includes: a connecting pipe 80 and a first adapter 60. The connecting pipe 80 includes a first connecting pipe 40 and a second connecting pipe 50. The first connecting pipe 40 is provided on the housing 11 and extends into the water tank 20, and the second connecting pipe 50 is connected to the cooling chamber 1. The first adapter 60 connects the first connecting pipe 40 and the second connecting pipe 50, and presses the first connecting pipe 40 on the housing 11.

[0070] By applying the technical solution of this embodiment, the first adapter 60 can connect the first connecting pipe 40 with the second connecting pipe 50. The above structure enables the coolant in the water tank 20 to flow smoothly into the second connecting pipe 50 through the first connecting pipe 40 and finally into the cooling chamber 1, or enables the coolant in the cooling chamber 1 to flow smoothly into the first connecting pipe 40 through the second connecting pipe 50 and finally into the water tank 20. In addition, in this embodiment, the first adapter 60 also presses the first connecting pipe 40 onto the housing 11. The above structure can prevent the first connecting pipe 40 from being separated from the first adapter 60 when the cooking appliance is working, thereby ensuring the reliability of the cooking appliance and solving the problem of poor reliability of the cooking appliance in the prior art.

[0071] In this embodiment, the first adapter 60 is made of a hard material. The above structure can ensure that there is no dead point at the connection between the first connecting tube 40 and the second connecting tube 50, thereby ensuring that the connecting channel at the connection between the first connecting tube 40 and the second connecting tube 50 is unobstructed, so that the coolant can flow smoothly between the water tank 20 and the cooling chamber 1.

[0072] like Figures 12 to 15 , Fig.17 and Fig.19 As shown, in this embodiment, the first adapter 60 includes a crimping plate 61, and the first connecting tube 40 is partially sandwiched between the housing 11 and the crimping plate 61. The above structure is simple and has a large crimping area, so that the first connecting tube 40 can be more firmly sandwiched between the housing 11 and the crimping plate 61. In addition, the above structure is simple and easy to process.

[0073] like Fig.14 , Fig.15 and Fig.17 As shown, in this embodiment, a mounting cylinder 114 for mounting the first connecting tube 40 is provided on the top wall 1111 of the groove, a mounting protrusion 115 is provided on the inner wall of the mounting cylinder 114, and a mounting groove 44 cooperating with the mounting protrusion 115 is provided on the side wall of the first connecting tube 40. The above structure is simple, and the first connecting tube 40 can be fixed on the housing 11 through the cooperation between the mounting protrusion 115 and the mounting groove 44, and pressed on the housing 11 by the pressing plate 61. The double fixation can further prevent the first connecting tube 40 from being separated from the first adapter 60, thereby further ensuring the reliability of the cooking utensil.

[0074] like Figures 13 to 18 As shown, in this embodiment, the first connecting pipe 40 includes a first connecting pipe body 41, a first annular flange 42 and a second annular flange 43 arranged at intervals at the end of the connecting pipe body 41, the first annular flange 42, the second annular flange 43 and the side wall of the connecting pipe body 41 together form a mounting groove 44, and the first annular flange 42 is sandwiched between the crimping plate 61 and the mounting protrusion 115. The above structure is simple and easy to process and assemble.

[0075] like Fig.15 , Fig.17 and Fig.19 As shown, in this embodiment, a sealing ring 611 is provided at the bottom of the crimping plate 61, and the sealing ring 611 is sealed with the upper surface of the first annular flange 42. The above structure can prevent the coolant from flowing out of the gap between the crimping plate 61 and the first annular flange 42, so as to prevent the housing 11 from being corroded.

[0076] like Fig.13 , Fig.15 and Fig.17 As shown, in this embodiment, the groove top wall 1111 is provided with mounting posts 116 extending away from the water tank 20, and two mounting posts 116 are provided on both sides of the mounting cylinder 114, and the pressing plate 61 is provided with second mounting holes 612 corresponding to the mounting posts 116. The above structure is simple, so that the pressing plate 61 can apply a continuous downward force to the first annular flange 42, so that the first annular flange 42 can be firmly clamped between the pressing plate 61 and the mounting protrusion 115.

[0077] like Fig.12 , Fig.15 and Fig.17 As shown, in this embodiment, the first adapter 60 further includes a connecting pipe 62 connecting the first connecting pipe 40 and the second connecting pipe 50. The above structure is simple and easy to process.

[0078] Since the second connecting pipe 50 is a hose, once the bending angle of the second connecting pipe 50 is too large, a dead point may appear in the second connecting pipe 50, resulting in an unsmooth flow of the coolant in the second connecting pipe 50. Fig.12 , Fig.13 , Fig.15 and Fig.17As shown, in this embodiment, the connecting pipe 62 includes a first pipe section 621 arranged transversely, the first pipe section 621 is connected to the second connecting pipe 50, and the first pipe section 621 forms a predetermined angle with the axis of the pot body 10 in the front-to-back direction to reduce the bending angle of the second connecting pipe 50. Since the first pipe section 621 forms a predetermined angle with the axis of the pot body 10 in the front-to-back direction, the second connecting pipe 50 connected to the first pipe section 621 will be smoothly arranged along the gap between the shell and the heating device, avoiding the situation where the bending angle of the second connecting pipe 50 is too large, thereby making the coolant in the second connecting pipe 50 flow smoothly.

[0079] like Fig.12 , Fig.13 , Fig.15 and Fig.17 As shown, in this embodiment, the connecting pipe 62 further includes a second pipe section 622 arranged vertically, the second pipe section 622 is connected to the first connecting pipe 40, and the second pipe section 622 is passed through the crimping plate 61. Since the second pipe section 622 is arranged vertically, the first connecting pipe 40 connected thereto is also arranged vertically, so that the outflow and inhalation of the coolant are smoother.

[0080] like Figures 15 to 18 As shown, in this embodiment, a guiding slope is provided at the end of the first connecting pipe 40 , and a matching slope that matches the guiding slope is provided at the end of the second pipe section 622 , so that the second pipe section 622 can smoothly extend into the first connecting pipe 40 .

[0081] In this embodiment, the connecting tube 62 and the crimping plate 61 are an integrated structure. The above structure is simple and easy to process. In addition, the above structure reduces the assembly steps and improves the production efficiency.

[0082] like Fig.12 , Fig.14 and Fig.21 As shown, in this embodiment, the water pump 30 includes: a first water pump 31 and a second water pump 32, the first water pump 31 is connected to the water tank 20 and the cooling chamber 1, the coolant enters the cooling chamber 1 through the first water pump 31, the second water pump 32 is connected to the water tank 20 and the cooling chamber 1, and the coolant in the cooling chamber 1 enters the water tank 20 through the second water pump 32, wherein the first connecting pipe 40 includes an inlet connecting pipe 40a and an outlet connecting pipe 40b, the inlet connecting pipe 40a is connected to the first water pump 31, and the outlet connecting pipe 40b is connected to the second water pump 32. The above structure enables the coolant to circulate between the water tank 20 and the cooling chamber 1 through the first water pump 31 and the second water pump 32.

[0083] like Fig.14 , Fig.16 and Fig.18As shown, in this embodiment, the length of the water inlet connecting pipe 40a is longer than the length of the water outlet connecting pipe 40b. The above structure makes the outflow and inhalation of the coolant smoother.

[0084] The installation process of the first connecting pipe 40 is described in detail below:

[0085] First, the first connecting tube 40 is inserted into the installation tube 114, and the installation groove 44 is matched with the installation protrusion 115. Then the first adapter 60 is pressed on the first connecting tube 40, and the end of the second tube section 622 gradually extends into the first connecting tube 40 during the downward pressing process. When the crimping plate 61 is pressed on the installation column 116, the second installation hole 612 on the crimping plate 61 is aligned with the installation hole in the installation column 116, and then the fastener is inserted into the second installation hole 612 and the installation hole in the installation column 116.

[0086] like Figure 1 , Fig.14 and Fig. 22 As shown, in this embodiment, two second protrusion structures 117 are provided on the connecting side wall 1113, and the two second protrusion structures 117 are respectively located on both sides of the connecting side wall 1113 in the horizontal direction, and a second matching structure 221 matching with the second protrusion structure 117 is provided on the first workpiece to position the first workpiece.

[0087] By applying the technical solution of this embodiment, two second protruding structures 117 are provided on the connecting side wall 1113, and the two second protruding structures 117 are respectively located on both sides of the connecting side wall 1113 in the horizontal direction. When assembling the first workpiece, align the second matching structure 221 of the first workpiece with the second protruding structure 117, and after alignment, push the first workpiece toward the rear of the pot body 10 until the first workpiece is installed in place. On the one hand, the above structure can prevent the first workpiece from moving in the left and right directions of the pot body 10, and makes the positioning of the first workpiece convenient and quick, improves the user experience, and solves the problem of poor user experience in the prior art. On the other hand, the above structure can increase the strength of the connecting side wall 1113 of the pot body 10, thereby ensuring the service life of the cooking utensil.

[0088] like Fig.14 As shown, in this embodiment, the second protrusion structure 117 extends from the groove top wall 1111 to the groove bottom wall 1112. The above structure makes it possible for there to be no gap between the top of the second protrusion structure 117 and the groove top wall 1111, and there to be no gap between the bottom of the second protrusion structure 117 and the groove bottom wall 1112. Therefore, dust will not accumulate at the connection between the second protrusion structure 117 and the groove top wall 1111 and the groove bottom wall 1112, making it convenient for users to clean and improving the user experience. In addition, the above structure makes the strength of the connecting side wall 1113 better, further ensuring the service life of the cooking utensil.

[0089] like Figure 1 , Fig.14 and Fig. 22 As shown, in the present embodiment, the second protruding structure 117 includes a first guiding bevel 1171 and a second guiding bevel 1172 connected to each other, and the first guiding bevel 1171 and the second guiding bevel 1172 are arranged at an angle. Specifically, the second matching structure 221 is a recessed structure. When assembling the first workpiece, align the second matching structure 221 of the first workpiece with the second protruding structure 117, and after alignment, push the first workpiece to the rear of the pot body 10, and when the side wall of the recessed structure cooperates with the first guiding bevel 1171 or the second guiding bevel 1172, push the first workpiece backward, and the first workpiece can enter the accommodating groove 111 along a predetermined direction. Therefore, the above structure can play a guiding role, so that the first workpiece can be smoothly installed in place. It should be noted that the above-mentioned first guiding bevel 1171 and the second guiding bevel 1172 are not limited to planes, but can also be curved surfaces.

[0090] like Figure 1 and Fig.14 As shown, in this embodiment, the second protrusion structure 117 further includes a transition surface 1173, which connects the first guide slope 1171 and the second guide slope 1172. The above structure makes the connection between the first guide slope 1171 and the second guide slope 1172 softer, which prevents the user from being scratched and makes the appearance more beautiful.

[0091] like Figure 1 , Fig.12 , Fig. 20 , Fig.24 and Fig. 27 As shown, in this embodiment, the first workpiece is a water tank 20, and the water tank 20 includes a first water tank side wall 21, a second water tank side wall 22, a third water tank side wall 23 and a fourth water tank side wall 24, and a water tank bottom wall 25, which are arranged opposite to each other. The first water tank side wall 21 is located on the side of the second water tank side wall 22 away from the connecting side wall 1113. When the water tank 20 is installed in the receiving groove 111, the third water tank side wall 23 and / or the fourth water tank side wall 24 are flush with the outer side wall of the shell 11. Specifically, in the above structure, the water tank 20 is U-shaped. When the water tank 20 is installed in the receiving groove 111, the third water tank side wall 23 and / or the fourth water tank side wall 24 can be flush with the surface of the shell 11 connected thereto. The above structure enables the outer side wall of the cooking utensil to form a complete cylindrical shape after the water tank 20 is installed, thereby making the appearance of the product more beautiful.

[0092] like Figure 1 , Fig.12 , Fig.21 , Fig. 22as well as Fig.24 As shown, in this embodiment, a second concave structure 118 is formed at the second protruding structure 117 connected to the inner surface of the side wall 1113 to avoid part of the heating device 13. Specifically, the second concave structure 118 is formed on the back of the second protruding structure 117, and the second concave structure 118 can avoid part of the heating device 13. In the above structure, the second protruding structure 117 can play a role in positioning the first workpiece, and the second concave structure 118 formed on the back of the second protruding structure 117 can also avoid part of the protruding heating device, thereby reducing the volume of the product.

[0093] like Figure 7 , Fig.21 and Fig.24 As shown, in this embodiment, the heating device 13 includes a heating device body 131 and a bracket 137 for fixing the heating device body 131 , and the second recessed structure 118 can avoid the bracket 137 .

[0094] like Fig.14 , Figure 21 to Figure 25 As shown, in this embodiment, the area enclosed by the outer shell 11 includes a high-temperature area away from the inner wall of the outer shell 11, and the connecting pipe 80 is passed with cooling liquid to reduce the temperature of the high-temperature area. The cooking utensil also includes: a limiting member 70, which is arranged on the inner wall of the outer shell 11, and the limiting member 70 limits the connecting pipe 80 to keep the connecting pipe 80 away from the high-temperature area.

[0095] By applying the technical solution of this embodiment, the connecting pipe 80 is limited by the limiting member 70, so that the connecting pipe 80 can be kept away from the high temperature area, thereby preventing the connecting pipe 80 from being damaged in a high temperature environment, thereby increasing the service life of the cooking utensil and solving the problem of short service life of the cooking utensil in the prior art.

[0096] like Figure 21 to Figure 25 As shown, in this embodiment, the heating device 13 forms a high temperature area when heating, at least part of the stopper 70 is located on the side of the connecting pipe 80 close to the heating device 13, and the connecting pipe 80 is limited between the stopper 70 and the inner wall of the housing 11 to prevent the connecting pipe 80 from moving toward the heating device 13. Since at least part of the stopper 70 is located on the side of the connecting pipe 80 close to the heating device 13, when the connecting pipe 80 moves toward the heating device 13, the stopper 70 will stop the connecting pipe 80 to prevent the connecting pipe 80 from continuing to move toward the heating device 13, thereby avoiding the connecting pipe 80 from contacting the heating device 13 with a higher temperature and preventing the connecting pipe 80 from being damaged by heat.

[0097] like Figure 22 to Figure 25As shown, in this embodiment, the stopper 70 includes a stopper plate 71 and a connecting plate 72, the stopper plate 71 is located on the side of the connecting pipe 80 close to the heating device 13, and the connecting plate 72 connects the stopper plate 71 and the housing 11. The above structure is simple and easy to process. Specifically, when the connecting pipe 80 moves toward the heating device 13, the stopper plate 71 will stop the connecting pipe 80 to prevent the connecting pipe 80 from continuing to move toward the heating device 13.

[0098] like Figure 3 As shown, in this embodiment, the edge of the stop plate 71 is connected to the edge of the connecting plate 72 away from the housing 11, and the angle between the stop plate 71 and the connecting plate 72 is between 80° and 150°.

[0099] like Fig.21 and Fig.25 As shown, in this embodiment, the second connecting pipe 50 includes a first connecting pipe section 51, a second connecting pipe section 52, and a second adapter 53 connecting the first connecting pipe section 51 and the second connecting pipe section 52. The first connecting pipe section 51 is connected to the first connecting pipe 40, the second connecting pipe section 52 is connected to the cooling chamber 1, and the stopper 70 cooperates with the second adapter 53. The above structure enables the coolant in the first connecting pipe section 51 and the second connecting pipe section 52 to communicate with each other. In this embodiment, the second adapter 53 is made of hard material to prevent the dead point from being generated at the connection between the first connecting pipe section 51 and the second connecting pipe section 52, so as to ensure the smoothness of the coolant flow.

[0100] like Fig.25 As shown, in this embodiment, the second adapter 53 includes a first horizontal section 531 and a first vertical section 532, and the first vertical section 532 abuts against the connecting plate 72 and is located between the stop plate 71 and the inner wall of the housing 11. Specifically, after installation, the first vertical section 532 abuts against the connecting plate 72, and the above structure can ensure that the first vertical section 532 can always be located between the stop plate 71 and the inner wall of the housing 11, thereby ensuring that the stop plate 71 can stop the first vertical section 532, and finally achieve the purpose of preventing the connecting pipe 80 from being damaged by heat.

[0101] In this embodiment, the stopper 70 and the housing 11 are integrally formed. The above structure is simple and easy to process.

[0102] like Figure 1 , Figure 3 and Fig.26 As shown, in this embodiment, an overflow channel 2 is provided on the pot body 10 , and the overflow channel 2 is located at the upper part of the cooling chamber 1 and is connected to the cooling chamber 1 . When the liquid level of the coolant is higher than a predetermined position, the coolant can flow out from the overflow channel 2 .

[0103] By applying the technical solution of this embodiment, when the liquid level of the coolant in the cooling chamber 1 is higher than the predetermined position, the coolant can flow out from the overflow channel 2, preventing the coolant from entering other areas in the pot body 10, avoiding the adverse effects of the overflow on the cooking utensils, thereby improving the user experience.

[0104] like Figure 1 , Figure 3 and Fig.26 As shown, in this embodiment, when the liquid level of the coolant in the cooling chamber 1 is higher than a predetermined position, the coolant can flow out from the overflow channel 2 into the water tank 20. The coolant flowing into the water tank 20 can be returned to the cooling chamber 1 through the water pump 30 to cool the inner pot 12. The above structure enables the coolant flowing out of the overflow channel 2 to be reused, thereby improving the utilization rate of the coolant.

[0105] like Fig.26 As shown, in this embodiment, the pot body 10 further includes a middle plate 14, which is arranged on the upper part of the shell 11, and the overflow channel 2 is formed on the middle plate 14. The cavity surrounded by the middle plate 14 is the overflow cavity 3. The overflow channel 2 is connected with the overflow cavity 3 and the cooling cavity 1. When the coolant enters the overflow cavity 3 and the liquid level of the coolant is higher than the overflow channel 2, the coolant can flow out from the overflow channel 2. The above structure is simple and easy to process and assemble.

[0106] like Figure 1 As shown, in this embodiment, the middle plate 14 includes a middle plate body 141 and an overflow pipe 142 penetrating the middle plate body 141, and an overflow channel 2 is formed inside the overflow pipe 142. When the coolant enters the overflow chamber 3 and the liquid level of the coolant is higher than the overflow channel 2, the coolant will flow from the inlet end to the outlet end of the overflow pipe 142. The above structure is simple and easy to implement.

[0107] like Figure 1 , Figure 3 and Fig.26 As shown, in this embodiment, a bypass port 1114 for bypassing the overflow pipe 142 is provided on the top wall 1111 of the groove. Specifically, after the middle plate 14 is installed in place, the outlet end of the overflow pipe 142 will pass through the bypass port 1114, and the outlet end of the overflow pipe 142 is located directly above the water tank 20. The above structure allows the coolant flowing out of the overflow pipe 142 to flow smoothly into the water tank 20.

[0108] like Fig.26As shown, in this embodiment, the overflow pipe 142 includes a second horizontal section 1421 and a second vertical section 1422, and the second vertical section 1422 extends into the avoidance opening 1114. The second vertical section 1422 is arranged toward the opening of the water tank 20, and the above structure enables the coolant to flow smoothly into the water tank 20. Of course, those skilled in the art should know that the second horizontal section 1421 does not only refer to a horizontally arranged pipe section, and the second horizontal section 1421 can also be arranged at a predetermined angle with the horizontal plane, wherein the inlet end of the second horizontal section 1421 is higher than the outlet end of the second horizontal section 1421, and the above structure further enables the water in the overflow chamber 3 to be smoothly discharged.

[0109] In this embodiment, the middle plate body 141 and the overflow pipe 142 are an integrally formed structure. The above structure is simple and easy to process. In addition, the above structure reduces the assembly steps of the overflow pipe 142, thereby improving the assembly efficiency.

[0110] like Figure 4 , Figure 6 and Fig.26 As shown, in this embodiment, a sealing structure 15 is provided between the middle plate 14 and the heating device 13 to prevent the coolant from flowing out from the gap between the middle plate 14 and the heating device 13. The above structure can seal the gap between the middle plate 14 and the heating device 13 to prevent damage to the electrical components caused by overflow.

[0111] like Figure 4 , Figure 6 and Fig.26 As shown, in this embodiment, the sealing structure 15 is a sealing ring. The above structure is simple, has good sealing performance, and is easy to assemble.

[0112] like Fig. 27 and Fig.28 As shown, in this embodiment, the heating device 13 is provided with a cooling liquid inlet 138, and the cooking appliance further comprises a stopper 139. The stopper 139 is arranged between the inner pot 12 and the cooling liquid inlet 138 so that the cooling liquid cannot be directly sprayed onto the inner pot 12.

[0113] By applying the technical solution of this embodiment, when the coolant enters the cooling cavity 1 from the coolant inlet 138, the coolant will first be stopped by the stopper 139. The coolant that has passed the stopper will not directly contact the inner pot 12. As the liquid level of the coolant entering the cooling cavity 1 rises, the inner pot 12 slowly immerses in the coolant, thereby greatly reducing the amount of generated steam, minimizing the amount of steam entering other areas of the pot body 10, reducing the adverse effects of steam on the cooking utensil, and thus improving the user experience.

[0114] like Fig. 27 and Fig.28As shown, in this embodiment, the stopper 139 is a stopper sheet. The above structure is simple and easy to process.

[0115] like Fig. 27 and Fig.28 As shown, in this embodiment, the stopper 139 is arranged on the heating device 13. The above structure is simple and easy to process. Of course, those skilled in the art should know that the stopper 139 can also be arranged on other structures, such as the middle plate.

[0116] In this embodiment, the stopper 139 and the heating device 13 are integrally formed. The above structure is simple and easy to process. In addition, the above structure reduces the installation steps of the stopper 139, thereby improving production efficiency. Preferably, the stopper 139 and the heating device 13 are integrally injection molded.

[0117] like Fig. 27 and Fig.28 As shown, in this embodiment, the heating device 13 includes a bottom 132 and a cylindrical portion 136 extending upward from the bottom 132, and a cooling chamber 1 containing a coolant is formed between the inner pot 12 and the bottom 132 and the cylindrical portion 136 of the heating device 13 for cooling the inner pot 12, and a stopper 139 is arranged at the connection between the bottom 132 and the cylindrical portion 136.

[0118] In this embodiment, the bottom 132 and the barrel 136 are integrally formed. The above structure is simple and easy to process. In addition, the above structure reduces the steps of installing the barrel 136 on the bottom 132, thereby improving production efficiency.

[0119] It should be noted that the heating device 13 in this embodiment has a bottom 132 and a barrel portion 136 located on the bottom 132, wherein a coil is provided on the bottom 132 for heating the inner pot 12, and the barrel portion 136 is used for heat preservation. Preferably, in this embodiment, the bottom 132 and the barrel portion 136 are an integral structure, but those skilled in the art should know that the bottom 132 and the barrel portion 136 can also be a separate structure, that is, the bottom 132 is a heating plate, and the barrel portion 136 is a heat preservation cover, and the heating plate and the heat preservation cover are assembled to form the heating device body 131.

[0120] It should also be noted that the heating device 13 includes a heating device body 131 and a bracket 137 , and the heating device body 131 includes a bottom 132 and a cylinder portion 136 .

[0121] like Fig.14 , Fig.21 and Fig.29As shown, in this embodiment, the water pump 30 includes: a first water pump 31 and a second water pump 32. The first water pump 31 is connected to the water tank 20 and the cooling chamber 1, and the coolant in the water tank 20 enters the cooling chamber 1 through the first water pump 31. The second water pump 32 is connected to the water tank 20 and the cooling chamber 1, and the coolant in the cooling chamber 1 enters the water tank 20 through the second water pump 32.

[0122] By applying the technical solution of this embodiment, the second water pump 32 pumps out the coolant in the cooling cavity 1, so that the coolant in the cooling cavity 1 can be pumped out as much as possible under the action of its own gravity and the external force generated by the second water pump 32, thereby ensuring the service life of the cooking appliance. In addition, since the first water pump 31 can control the flow rate of the coolant entering the cooling cavity 1, and the second water pump 32 can control the flow rate of the coolant flowing out of the cooling cavity 1, it is possible to ensure that the liquid level of the coolant is within a predetermined range, preventing the coolant from overflowing the cooling cavity, thereby improving the user experience and solving the problem of poor user experience of cooking appliances in the prior art.

[0123] In this embodiment, the cooking appliance further includes a control unit. The control unit is electrically connected to the first water pump 31 and the second water pump 32. When the control unit receives the first signal, the first water pump 31 works. When the control unit receives the second signal, the control unit controls the first water pump 31 and the second water pump 32 to work simultaneously, so that the coolant can circulate in the water tank 20 and the cooling chamber 1. When the control unit receives the third signal, the first water pump 31 stops working, and the second water pump 32 continues to work. When the control unit receives the fourth signal, the second water pump 32 stops working. Specifically, when it is necessary to quickly reduce the pressure in the inner pot 12, the first water pump 31 is started, and the first water pump 31 begins to pass the coolant into the cooling chamber 1. When the liquid level of the coolant in the cooling chamber 1 reaches a predetermined range, or the first water pump 31 passes the coolant for a predetermined time, the second water pump 32 is turned on. At this time, the first water pump 31 continues to pass the coolant into the cooling chamber 1, and the second water pump 32 begins to discharge the coolant in the cooling chamber 1. The above scheme can ensure the circulation of the coolant in the water tank 20 and the cooling chamber 1, so as to achieve the purpose of quickly reducing the temperature of the inner pot 12. In addition, since the flow rate of the first water pump 31 and the second water pump 32 pumping and extracting the coolant is controllable, the coolant in the cooling chamber 1 can always be kept within a predetermined range to prevent the coolant from overflowing from the cooling chamber 1. When the temperature of the inner pot 12 is reduced to a predetermined temperature, the first water pump 31 can be stopped, that is, the first water pump 31 stops passing the coolant into the cooling chamber 1. The second water pump 32 continues to work, and at this time, the coolant in the cooling chamber 1 will be completely pumped into the water tank 20 to achieve the recovery of the coolant.

[0124] like Fig.26 As shown, in this embodiment, the cooling chamber 1 is communicated with the outside.

[0125] like Fig.26 As shown, in this embodiment, the heating device 13 includes a bottom 132 and a barrel portion 136 extending upward from the bottom 132, and a cooling chamber 1 for containing cooling liquid is formed between the inner pot 12 and the bottom 132 and the barrel portion 136 of the heating device 13, and an opening is formed between the top of the inner pot 12 and the top of the barrel portion 136 to communicate with the outside. The above structure makes the volume of the cooling chamber 1 larger, and the outer surface of the inner pot 12 can contact the cooling liquid in the cooling chamber 1 as much as possible, thereby increasing the opening speed of the lid.

[0126] In this embodiment, the first water pump 31 is a one-way pump. The above structure is simple and low in cost.

[0127] In this embodiment, the first water pump 31 is a bidirectional pump. When the pressure in the inner pot 12 needs to be quickly reduced, the first water pump 31 is started, and the first water pump 31 begins to pass coolant into the cooling chamber 1. When the temperature of the inner pot 12 is reduced to a predetermined temperature, the first water pump 31 can be reversely started, that is, the first water pump 31 stops passing coolant into the cooling chamber 1. The second water pump 32 continues to work, and at this time, the coolant in the cooling chamber 1 will be completely pumped into the water tank 20 to achieve the recovery of the coolant. When the coolant in the cooling chamber 1 is reduced to a predetermined height or is completely pumped out, the first water pump 31 can be reversely started, so that the coolant in the first water pump 31 can be completely recovered into the water tank 20. The above structure ensures that there is no residual coolant in the first water pump 31, thereby increasing the life of the first water pump 31.

[0128] In this embodiment, the second water pump 32 is a one-way pump. The above structure is simple and low in cost.

[0129] like Figure 29 to Figure 31 As shown, in this embodiment, the water pump 30 is located at the front of the pot body 10, and the axis of the water pump 30 is arranged at a predetermined angle with the axis of the pot body 10 in the front-rear direction.

[0130] By applying the technical solution of this embodiment, since the water pump 30 is located at the front of the pot body 10, the length of the water pump 30 in the front-to-back direction of the pot body 10 determines the overall length of the cooking utensil in the front-to-back direction. Therefore, in this embodiment, the axis of the water pump 30 is arranged at a predetermined angle to the axis of the pot body 10 in the front-to-back direction. The above structure can shorten the length of the water pump 30 in the front-to-back direction, that is, shorten the length of the cooking utensil in the front-to-back direction, thereby reducing the product volume of the cooking utensil, and solving the problem of large volume of the cooking utensil in the prior art.

[0131] It should be noted that, in this embodiment, the cooking utensil includes a pot body 10 and a pot cover disposed on the pot body, one side of the pot cover is pivotally connected to the pot body 10, and the other side of the pot cover is clamped to the pot body 10 through a clamping structure. In this embodiment, the front of the pot body 10 refers to the side where the clamping structure is located, and the rear of the pot body refers to the side where the pivot axis of the pivot connection is located.

[0132] like Fig.31 As shown, in this embodiment, the cooking utensil includes a third connecting pipe section 54 and a fourth connecting pipe section 55, a water pump 30 connects the third connecting pipe section 54 and the fourth connecting pipe section 55, a free end of the third connecting pipe section 54 is connected to the cooling chamber 1, and a free end of the fourth connecting pipe section 55 is connected to the water tank 20, the water pump 30 includes a first end 33 and a second end 34, a pump port of the water pump 30 is located at the first end, and in the direction from the second end 34 to the first end 33, the distance between the axis of the water pump 30 and the pot body 10 in the front-to-back direction gradually increases, so that the fourth connecting pipe section 55 is away from the heating device 13. The above structure enables the fourth connecting pipe section 55 to be away from the heating device 13 with a higher temperature, thereby preventing the fourth connecting pipe section 55 from being damaged by heat, thereby ensuring the service life of the cooking utensil.

[0133] like Fig.21 As shown, in this embodiment, the cooking utensil includes a second connecting pipe 50. The second connecting pipe 50 includes a first connecting pipe section 51, a second connecting pipe section 52, and a second adapter 53 connecting the first connecting pipe section 51 and the second connecting pipe section 52, the third connecting pipe section 54 and the fourth connecting pipe section 55 form the second connecting pipe section 52, and the free end of the fourth connecting pipe section 55 is connected to the water tank 20 through the first connecting pipe section 51.

[0134] like Fig.14 and Fig.21 As shown, in this embodiment, the cooking appliance includes: a first connecting pipe 40 and a first adapter 60. The first connecting pipe 40 is provided on the housing 11 and extends into the water tank 20. The first adapter 60 connects the first connecting pipe 40 with the second connecting pipe 50, and the first connecting pipe section 51 of the second connecting pipe 50 is connected with the water tank 20 through the first connecting pipe 40.

[0135] like Fig.31 As shown, in this embodiment, the angle between the axis of the water pump 30 and the axis of the pot body 10 in the front-rear direction is between 8 and 50 degrees. The above structure further enables the fourth connecting pipe section 55 to be away from the heating device 13 with a higher temperature, thereby preventing the fourth connecting pipe section 55 from being damaged by heat.

[0136] like Fig.31As shown, in this embodiment, the water pump 30 is located at the bottom of the housing 11 on one side close to the water tank 20. The above structure allows the water pump 30 to be as far away from the heating device 13 as possible, so that the temperature of the coolant in the water pump 30 and the second connecting pipe 50 is as low as possible, thereby ensuring the heat absorption capacity of the coolant. In addition, the water pump 30 is arranged below the water tank 20 with a lower temperature so that the water pump 30 can be as far away from the high temperature area as possible, thereby ensuring the service life of the water pump 30.

[0137] like Fig.31 As shown, in this embodiment, the first water pump 31 and the second water pump 32 are symmetrical with respect to the axis of the pot body 10 in the front-rear direction. The above structure is simple and easy to assemble.

[0138] like Fig.30 As shown, in this embodiment, the pot body 10 further includes a bottom shell 16 located below the outer shell 11, the heating device 13 and the inner pot 12. The bottom shell 16 is provided with a heat dissipation hole 161. The projection of the heat dissipation hole 161 on the horizontal plane does not overlap with the projection of the water pump 30 on the horizontal plane. The above structure ensures that even if the user inserts his finger into the heat dissipation hole 161, the water pump 30 will not be touched, thereby meeting the safety requirements. It should be noted that Fig.30 The bottom view of the pot body is shown, from which the heat dissipation hole 161 can be seen, and the two sides of the heat dissipation hole 161 have baffles for shielding the water pump 30. If the axis of the water pump 30 is in the same direction as the axis of the pot body 10 in the front-to-back direction, the length of the baffle in the front-to-back direction of the pot body 10 will be longer, so that the area of ​​the heat dissipation hole 161 becomes smaller. If the axis of the water pump 30 is set at a predetermined angle with the axis of the pot body 10 in the front-to-back direction. Then the length of the water pump 30 in the front-to-back direction of the pot body 10 will be shorter, and the length of the baffle shielding the water pump 30 in the front-to-back direction of the pot body 10 will also be shortened accordingly, so that the area of ​​the heat dissipation hole 161 can be set larger. Therefore, setting the axis of the water pump 30 at a predetermined angle with the axis of the pot body 10 in the front-to-back direction can improve the heat dissipation capacity of the cooking appliance.

[0139] like Fig.29 and Fig.30 As shown, in this embodiment, the pot body 10 includes a bottom shell 16 disposed below the outer shell 11 , and the bottom shell 16 is installed after the water pump 30 is installed on the outer shell 11 .

[0140] By applying the technical solution of this embodiment, during installation, the water pump 30 is first installed on the housing 11, and the components connected to the water pump 30 are fixed. Finally, the bottom shell 16 is placed under the housing 11 to complete the installation. In the above structure, since the water pump 30 is not on the bottom shell 16, the interference between the water pump 30 and the housing 11 or other components is avoided when the bottom shell 16 is installed, so that the installation is convenient, the installation efficiency is improved, and the problem of inconvenient installation of the cooking utensils in the prior art is solved. In addition, since the water pump 30 is installed on the housing 11 in advance, the position of the pipeline connected to the water pump 30 can be fixed in advance, and then the bottom shell 16 is placed under the housing 11. That is to say, after the bottom shell 16 is installed, the position of the pipeline connected to the water pump 30 will not be displaced. Therefore, the above structure can avoid the contact between the pipeline and the heating device 13, prevent the pipeline from being damaged by heat, and finally ensure the service life of the cooking utensils.

[0141] like Figure 4 , Figure 5 and Fig.31 As shown, in this embodiment, the water pump 30 is arranged at the bottom of the groove bottom wall 1112. The above structure is simple and easy to assemble.

[0142] In this embodiment, the cooking appliance is an electric pressure cooker.
