[0002] The pot is a widely used kitchen utensil in people's daily life and is an essential tool in cooking. Commonly used cooking utensils include frying pans, soup pots, induction cookers, electric rice cookers, and steamers. With the rapid development of intelligent devices, sensors are increasingly used in kitchen equipment. The latest function of intelligent pots is temperature measurement.

[0003] Currently, the temperature measurement of intelligent pots is mainly achieved by temperature sensors such as thermocouples. A temperature measurement groove is usually formed on the outer wall of the pot body to accommodate a temperature measurement component for measuring the temperature of the pot. To improve the accuracy of temperature measurement and enhance the temperature control accuracy of the pot, the temperature measurement groove usually extends to the bottom of the pot body. A groove cover is usually welded on the temperature measurement groove to hide and protect the temperature measurement assembly.

[0004] However, the formation of the temperature measurement groove on the outer wall of the bottom of the pot body damages the outer surface of the bottom of the pot body, causing partial obstruction of the magnetic circuit of the pot, affecting the induction heating effect of the pot, and reducing the accuracy of temperature measurement. SUMMARY

[0005] The present application provides a pot and a manufacturing method thereof to solve the problem of the existing pot that the formation of the temperature measurement groove on the outer wall of the bottom of the pot body causes partial obstruction of the magnetic circuit of the pot, affecting the induction heating effect of the pot, and reducing the accuracy of temperature measurement.

[0006] The first aspect of the present application provides a pot, comprising: a pot body, the pot body wall of the pot body has a plurality of pipelines inside for accommodating temperature measurement components;

[0007] The pot body wall includes a bottom wall and a side wall surrounding the bottom wall. The pipeline includes a first channel and a second channel in communication. The first channel is located in the bottom wall, and at least part of the second channel is located in the side wall. The second channel has a first opening at an end away from the first channel. The first opening is used for the temperature measurement component to pass through and enter the pipeline.

[0008] By comprising a pot body, a plurality of pipelines for accommodating temperature measuring members are arranged inside a pot body wall of the pot body, wherein the pot body wall comprises a bottom wall and a side wall surrounding the bottom wall, the pipelines comprise a first channel and a second channel connected to each other, the first channel is located in the bottom wall, at least part of the second channel is located in the side wall, and the second channel has a first opening at an end away from the first channel, the first opening is used for the temperature measuring member to pass through and enter the pipeline, that is, the pipeline for arranging the temperature measuring member is located inside the pot body wall, the temperature measuring member can be inserted into the bottom wall of the pot body through the pipeline, the bottom wall of the pot body can be accurately measured while the outer wall surface of the bottom wall of the pot body is not damaged, the effect of inductive heating of the pot is ensured, and the accuracy of temperature measurement of the pot is effectively improved.

[0009] In a possible implementation, the second channel is two, one of which is located on one side or the opposite side of the other.

[0010] In this way, the temperature measuring member can be inserted into the first channel from the first opening of any second channel to reach a specified position, which helps to improve the installation efficiency of the temperature measuring member. Meanwhile, when the pot is manufactured, the second channel is two, and the side edge segment of the pipeline member used is also two, which can facilitate the fixation of the pipeline member and the formation of the pipeline in the inner wall of the pot body.

[0011] In a possible implementation, the pot body wall has a plurality of the pipelines.

[0012] Any two or more of the plurality of pipelines are connected to each other, and / or the plurality of pipelines are not connected to each other.

[0013] In this way, a plurality of temperature measuring members can be arranged inside the pot body wall, multi-point temperature measurement of the bottom of the pot can be realized, and the accuracy of temperature measurement of the pot is improved. Meanwhile, different temperature measurement functions can be realized according to different use scenarios, which helps to improve the functionality of the pot.

[0014] In a possible implementation, a pipeline member is further included, an opening end of the pipeline member forms the first opening, and at least part of the pipeline member is embedded in the pot body wall to form the pipeline.

[0015] In this way, the pipeline member is embedded in the pot body wall to form the pipeline inside the pot body wall, which is convenient to realize and has a low cost.

[0016] In a possible implementation, the pipeline member comprises a side edge segment and a bottom edge segment, the side edge segment forms the second channel, the bottom edge segment forms the first channel, an opening end of the pipeline member is located at an end of the side edge segment away from the bottom edge segment, the side edge segment and the bottom edge segment are connected through a first transition segment, and the first transition segment is arc-shaped.

[0017] Since the side edge segment of the pipe member is located in the side wall and the bottom edge segment is located in the bottom wall, the plane where the side wall and the bottom wall are generally perpendicular, the first transition segment connecting the side edge segment and the bottom edge segment is arc-shaped, which can facilitate the temperature measuring member to extend from the side edge segment into the bottom edge segment and facilitate the temperature measuring member to extend into the first channel.

[0018] In a possible implementation, the opening end of the pipe member is located on the end face of the end of the side wall away from the bottom wall; and / or, the opening end of the pipe member is located on the outer wall face of the side wall.

[0019] In this way, the side edge segment of the pipe member is entirely inside the side wall, that is, the second channel is entirely located in the side wall, so that the pipe member is entirely located in the wall of the pot after the pot is formed, which can improve the aesthetic appearance of the pot.

[0020] In a possible implementation, the side edge segment includes a body part located inside the side wall and an extension part extending to the outside of the side wall, and the opening end of the pipe member is located on the end of the extension part away from the body part.

[0021] The extension part includes an inlet segment, a second transition segment and a connecting segment, the connecting segment is parallel to and connected with the body part, the inlet segment is arranged at an angle with the connecting segment, the inlet segment and the connecting segment are connected through the second transition segment, and the second transition segment is arc-shaped.

[0022] In this way, after the pot is formed, the pot body further includes the extension part, the temperature measuring member can enter the pipe from the end of the extension part away from the body part and even realize temperature measurement in the bottom wall of the pot body. The provision of the extension part can facilitate the fixed connection of the pipe member and the pot body mold during the forming of the pot.

[0023] In addition, the inlet segment of the extension part is arranged at an angle with the connecting segment, which can increase the length of the extension part in the horizontal direction, facilitate the connection of the pipe member and the pot body through the extension part, and enable the inlet segment to be connected with the connecting segment through the second transition segment, and the second transition segment is arc-shaped, which can facilitate the temperature measuring member to pass through the inlet segment and extend into the connecting segment, and then facilitate the temperature measuring member to extend into the first channel to realize temperature measurement of the pot.

[0024] In a possible implementation, the extension part extends from the end face of the end of the side wall away from the bottom wall to the outside of the side wall; and / or, the extension part extends from the side face of the side wall to the outside of the side wall.

[0025] In a possible implementation, the arc of the first transition segment and / or the second transition segment is greater than or equal to 10 mm.

[0026] When the arc of the first transition section and the second transition section is too small, the temperature measuring member is inconvenient to pass through the first transition section and the second transition section into the bottom section, thus, the arc of the first transition section and / or the second transition section is greater than or equal to 10 mm, which can ensure that the temperature measuring member can smoothly pass through the first transition section and the second transition section and extend into the bottom section, i.e., extend into the first channel.

[0027] In a possible implementation, the pipeline member is provided with a blocking member, which is used to block and limit the temperature measuring member.

[0028] In this way, the blocking member can limit the extending position of the temperature measuring member, so that the temperature measuring member extends to a specified position.

[0029] In a possible implementation, the pipeline member is integrally embedded in the wall of the pot when the pot is formed.

[0030] In this way, the pipeline member is integrally embedded in the inner wall of the pot when the pot is formed, so that a pipeline is formed inside the inner wall of the pot, which is easy to implement, the method is relatively simple, and the cost is relatively low.

[0031] In a possible implementation, the outer wall of at least part of the pipeline member is provided with a strengthening portion protruding outward.

[0032] The strengthening portion can improve the strength of the pipeline member and reduce the probability of deformation of the pipeline member under long-time high-temperature use. In addition, when the pipeline member is integrally embedded in the wall of the pot when the pot is formed, the setting of the strengthening portion enhances the strength of the pipeline member, which can reduce the deformation of the pipeline member in the process of pressure casting or high-temperature pouring to form the pot, and improve the qualification rate of the pot forming.

[0033] In a possible implementation, the pipeline member is provided with a fixing member, which is used to be fixedly connected with a forming mold of the pot.

[0034] In this way, the fixing member fixes the pipeline member with the mold, which avoids the movement of the pipeline member in the mold during the forming process. In particular, for the pipeline member including only one side section, the setting of the fixing member can ensure that the pipeline member can be accurately embedded in the inner wall of the pot, thereby improving the qualification rate of the pot forming.

[0035] In a possible implementation, the pipeline member is provided with a fixing member, which is used to be fixedly connected with a forming mold of the pot.

[0036] In this way, the fixing member fixes the pipeline member with the mold, which avoids the movement of the pipeline member in the mold during the forming process. In particular, for the pipeline member including only one side section, the setting of the fixing member can ensure that the pipeline member can be accurately embedded in the inner wall of the pot, thereby improving the qualification rate of the pot forming.

[0037] In a possible implementation, a sealing member is further included, and the sealing member seals the first opening.

[0038] In this way, after the temperature measuring member is inserted into the pipeline through the first opening and reaches the designated position, the pipeline member can be sealed by the sealing member, so that oil fume and water vapor cannot enter the pipeline member through the first opening, which is convenient for cleaning and can prevent damage to the temperature measuring member in the pipeline member, thereby prolonging the service life of the temperature measuring member.

[0039] The second aspect of the present application provides a manufacturing method of a pot, the method comprising:

[0040] A pipeline member, an upper mold and a lower mold corresponding to the upper mold are provided, the upper mold and the lower mold each include a bottom surface and a side surface surrounding the bottom surface, and the pipeline member includes a side edge segment and a bottom edge segment in communication, and the side edge segment has a second opening at an end away from the bottom edge segment;

[0041] The upper mold and the lower mold are closed, a casting gap is formed between the lower mold and the upper mold, the pipeline member is arranged inside the casting gap, at least part of the side edge segment corresponds to the side surface of the upper mold and the lower mold, the bottom edge segment corresponds to the bottom surface of the upper mold and the lower mold, and the second opening is exposed outside the casting gap;

[0042] Casting is performed, and the mold is opened.

[0043] The pot obtained by the above method, the pipeline member forms a pipeline inside the wall of the pot body, the temperature measuring member can enter the pipeline member through the second opening, that is, enter the pipeline and reach the first channel in the bottom wall, so as to detect the temperature of the bottom of the pot body, and since the pipeline formed by the pipeline member is located inside the wall of the pot body, the pipeline for accommodating the temperature measuring member will not damage the outer surface of the bottom of the pot body, avoid blocking the magnetic circuit of the pot, ensure the effect of induction heating of the pot, and effectively improve the accuracy of temperature measurement of the pot.

[0044] In addition, compared with the existing slotting method at the bottom of the pot, there is no need to additionally set a slot cover or the like for hiding the temperature measuring member by welding or the like, which can avoid problems such as deformation and falling off of the slot cover due to long-time heating, and improve the use stability and service life of the pot.

[0045] In a possible implementation, the pipeline member includes two side edge segments, one of which is located on one side or the opposite side of the other side edge segment.

[0046] Thus, the pipe piece can be fixed with the upper die and / or the lower die through the side edge segments, the two side edge segments can improve the stability of the pipe piece fixed with the upper die and / or the lower die, facilitate the fixation, and ensure the stability of the setting position of the pipe piece. In addition, the two side edge segments also form two second passages in the side wall of the pot body wall, the temperature measuring piece can be inserted into the first passage from any one of the second passages to reach the specified position, which helps to improve the installation efficiency of the temperature measuring piece.

[0047] In a possible implementation, the setting of the pipe piece inside the casting gap comprises:

[0048] The plurality of pipe pieces are set inside the casting gap, and any two or more pipe pieces are connected.

[0049] Thus, after the above method is used for forming, a plurality of pipelines can be formed inside the pot body wall, so that a plurality of temperature measuring pieces can be accommodated and set inside the pot body wall, and multi-point temperature measurement of the bottom of the pot can be realized, and the accuracy of the temperature test of the pot is improved.

[0050] In addition, the first passage in the plurality of pipelines can also extend to different positions in the bottom wall, expand the temperature measurement range of the pot, and also realize different temperature measurement functions according to different use scenarios, which helps to improve the functionality of the pot.

[0051] In a possible implementation, the side edge segment comprises a body part and an extension part, the second opening is located on one end of the extension part away from the body part, and the setting of the pipe piece inside the casting gap comprises:

[0052] The body part corresponds to the side surface of the upper die and the lower die, and the extension part extends out of the casting gap.

[0053] Thus, after casting forming, part of the second passage is located in the side wall, and part of the second passage extends out of the side wall. The extension part extending out can be used for fixing with the upper die and / or the lower die, facilitating the fixation of the pipe piece.

[0054] In a possible implementation, the extension part extends from one end of the casting gap away from the bottom surface of the upper die and the lower die to the outside of the casting gap; and / or, the extension part extends from the side surface of the lower die to the outside of the casting gap.

[0055] In a possible implementation, the pot further comprises a temperature measuring piece, and after the casting forming and demolding, the pot further comprises:

[0056] The temperature measuring piece is inserted into the pipe piece through the second opening;

[0057] The second opening is sealed by a sealing member.

[0058] In a possible implementation, the pot further comprises a temperature measuring member, and after the casting forming, the pot further comprises:

[0059] The extension part is cut off, and a third opening is formed on the pipeline member;

[0060] The temperature measuring member is inserted into the pipeline member through the third opening;

[0061] The third opening is sealed by a sealing member.

[0062] In this way, after the pot is formed, the extension part extending outside the casting gap is cut off, that is, the extension part extending outside the pot wall is cut off, that is, while the pipeline member is fixed to the pot by the extension part, the excess pipeline member part is cut off, which can improve the appearance of the pot after forming.

[0063] In a possible implementation, the upper die and the lower die opposite one side have a first groove opposite the extension part, and the first groove cooperates with the extension part to fix the pipeline member in the casting gap. In this way, the extension part can be inserted into the first groove and cooperate with the second groove, so that the pipeline member is fixed by the first groove, and the pipeline member is fixed inside the casting gap.

[0064] And / or, the lower die and the upper die opposite one side have a second groove opposite the extension part, and the second groove cooperates with the extension part to fix the pipeline member in the casting gap. In this way, the extension part can be inserted into the second groove and cooperate with the second groove, so that the pipeline member is fixed by the second groove, and the stability of the pipeline member in the casting gap is further ensured.

[0065] In a possible implementation, of the two sides of the pipeline member opposite the first groove, one side has a first fixing member, and the other side has a first limiting hole cooperating with the first fixing member.

[0066] In this way, the pipeline member can be fixed in the first groove by cooperation of the first fixing member and the first limiting hole, and the displacement of the pipeline member in the first groove can be limited. Especially when the pipeline member only includes one side edge segment and one bottom edge segment, the setting of the first fixing member and the first limiting hole (and / or the second fixing member and the second limiting hole) can effectively fix the pipeline member, further improve the setting stability of the pipeline member in the casting gap, and help to improve the qualified rate of the pot.

[0067] And / or, one of the two sides of the pipe piece opposite to the second groove has a second fixing piece, and the other side has a second limiting hole matched with the second fixing piece.

[0068] In this way, the pipe piece can be fixed in the second groove through the cooperation of the second fixing piece and the second limiting hole, the displacement of the pipe piece in the second groove is limited, and the setting stability of the pipe piece in the casting gap can be further improved.

DETAILED DESCRIPTION

[0088] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0089] At present, intelligent life has been rapidly developed. Taking kitchen utensils as an example, temperature measuring pots capable of measuring temperature to automatically adjust heating temperature are very popular. Generally, the intelligent temperature measuring pot mainly realizes temperature detection through a sensor such as a thermocouple. Specifically, a temperature measuring groove for accommodating the temperature measuring piece such as a thermocouple is arranged on the outer wall of the pot, and the temperature of the pot is sensed through the temperature measuring piece. In order to improve the accuracy of pot temperature measurement, the temperature measuring groove is usually extended to the bottom of the pot body, so that the temperature measuring end of the temperature measuring piece can extend to the bottom of the pot body. In order to protect the temperature measuring piece, a groove cover is arranged on the temperature measuring groove by welding or other methods.

[0090] However, in the above temperature measuring pot, the temperature measuring groove arranged on the outer wall of the bottom of the pot body will damage the outer surface of the bottom of the pot body, thereby affecting the magnetic circuit of the pot, causing partial obstruction of the magnetic circuit of the pot, affecting the effect of inductive heating of the pot, and reducing the temperature measurement accuracy of the pot.

[0091] Based on the above technical problems, the embodiments of the present application provide a pot and a manufacturing method thereof. The pot comprises a pot body, and a plurality of pipelines for accommodating temperature measuring pieces are arranged inside the pot body wall of the pot body. The pot body wall comprises a bottom wall and a side wall surrounding the bottom wall. The pipelines comprise a first channel and a second channel connected in communication. The first channel is located in the bottom wall, and at least part of the second channel is located in the side wall. The second channel has a first opening at an end away from the first channel. The first opening is used for allowing the temperature measuring piece to pass through and enter the pipeline. That is, the pipeline for arranging the temperature measuring piece is located inside the pot body wall. The temperature measuring piece can extend into the bottom wall of the pot body through the pipeline. The temperature of the bottom of the pot body can be accurately measured without damaging the outer surface of the bottom of the pot body. The effect of inductive heating of the pot is ensured, and the temperature measurement accuracy of the pot is effectively improved.

[0092] The pot and the manufacturing method thereof provided by the embodiments of the present application will be described in detail below in combination with the drawings and specific embodiments.

[0093] Embodiment one

[0094] Figure 1 is a structural schematic diagram of a pot provided by the embodiments of the present application, Figure 2 is a structural schematic diagram of a pot body and a temperature measuring piece provided by the embodiments of the present application, Figure 3 is a structural schematic diagram of another pot provided by the embodiments of the present application, Figure 4 is Figure 3 is a partial enlarged view of part a in FIG. 8. Figure 5 is a structural schematic diagram of another pot provided by the embodiments of the present application, Figure 6 is Figure 5 is a partial enlarged view of part b in FIG. 9, Figure 7 is Figure 5A local enlarged view of part c, Figure 8 is a structural schematic view of a pipe provided by an embodiment of the present application; Figure 9 is Figure 6 A local enlarged view of part d.

[0095] Referring to Figures 1 to 3 , the pot provided by the embodiment of the present application can be an electric pressure cooker, an electric rice cooker, an electric kettle, a food processor, etc., or can also be a pot used in combination with a heating element such as an induction cooker.

[0096] The pot 100 comprises a pot body 10, and the pot body 10 has a plurality of pipe lines 12 for accommodating temperature measuring elements 20 inside a pot body wall 11 of the pot body 10.

[0097] The pot body wall 11 can comprise a bottom wall 111 and a side wall 112 surrounding the bottom wall 111, and the bottom wall 111 and the side wall 112 jointly surround a cavity of the pot body 10 for containing food, and the pipe line 12 comprises a first channel 121 and a second channel 122 in communication, the first channel 121 is located in the bottom wall 111, and specifically, the first channel 121 can be located at any position inside the bottom wall 111, which can be set according to the position required for temperature measurement.

[0098] At least part of the second channel 122 is located in the side wall 112, and the second channel 122 has a first opening 1221 on an end thereof away from the first channel 121, and the first opening 1221 is used for allowing the temperature measuring element 20 to pass through and enter the pipe line 12, that is, the temperature measuring element 20 can enter the pipe line 12 through the first opening 1221 on the pipe line 12, extend into the first channel 121 through the second channel 122, that is, extend into the bottom wall of the bottom of the pot body 10, so as to realize measurement of the temperature of the bottom of the pot body 10 and improve the accuracy of temperature measurement.

[0099] Since the pipe line 12 is located inside the pot body wall 11, and the first channel 121 corresponding to the bottom wall of the pot body 10 is also located inside the bottom wall 111, the pipe line 12 for accommodating the temperature measuring element 20 will not cause damage to the outer surface of the bottom of the pot body 10, thereby avoiding the problem of blocking the magnetic circuit of the pot 100 and ensuring the effect of induction heating of the pot 100, so as to effectively improve the precision of temperature measurement of the pot 100.

[0100] As Figure 2As shown, the pot 100 can include a temperature measuring element 20, which extends into the pipeline 12 through the first opening 1221. The temperature measuring element 20 can include a lead wire and a temperature measuring element connected to the lead wire. The temperature measuring element, as the temperature measuring end of the temperature measuring element 20, can extend into the bottom wall 111 corresponding to the center of the bottom wall 111 after passing through the first opening 1221. In this way, the temperature measuring element 20 can detect the temperature at the center of the bottom of the pot body 10, which can more accurately detect the current temperature of the pot 100 and improve the accuracy of temperature measurement of the pot 100.

[0101] In addition, referring to Figure 3 and Figure 4 As shown, since the pipeline 12 is located inside the pot wall 11, after the temperature measuring element 20 extends into the first channel 121, the temperature measuring element 20 is also located inside the pot wall 11. Compared with the existing slot at the bottom of the pot 10, there is no need to additionally set a slot cover or the like for hiding the temperature measuring element 20 by welding or the like, which can avoid problems such as deformation and falling off of the slot cover due to long-term heating, and improve the use stability and service life of the pot 100.

[0102] As shown in Figure 3 The pot 100 can also include a sealing element 30, which is sealingly arranged in the first opening 1221. Specifically, after the temperature measuring element 20 extends into the pipeline 12 through the first opening 1221 and extends to the specified position, the pipeline element 13 can be sealed by the sealing element 30. This can prevent oil smoke and water vapor from entering the pipeline element 13 through the first opening 1221, which is not convenient for cleaning and can damage the temperature measuring element 20 located in the pipeline element 13, thereby helping to improve the service life of the temperature measuring element 20.

[0103] As shown in Figures 1 to 3 The second channel 122 can be entirely located in the side wall 112, or as shown in Figure 5 The second channel 122 can be partially located in the side wall 112, and the other part of the second channel 122 extends out of the side wall 112.

[0104] Specifically, as shown in Figure 3 and Figure 5 The pot 100 further includes a pipeline element 13, one end of which is open to form a first opening 1221, and at least part of the pipeline element 13 is embedded in the pot wall 11 to form a pipeline 12. The pipeline element 13 can have a cavity to form a cavity in the pot wall 11 for accommodating the temperature measuring element 20, i.e., to form the pipeline 12 in the pot wall 11. The temperature measuring element extends into the pipeline element 13 through the open end of the pipeline element 13, i.e., into the pipeline 12. As shown in Figure 3 The pipeline element 13 can be entirely embedded in the pot wall 11, or as shown inFigure 5 As shown, part of the pipe piece 13 is embedded in the pot wall 11, and part of the pipe piece 13 extends out of the pot wall 11.

[0105] Specifically, the pipe piece 13 can be integrally embedded in the pot wall 11 when the pot 100 is formed, for example, the pot body 10 can be formed by mold casting or pressure casting, and the pipe piece 13 can be located in the mold and integrally formed with the pot body 10, and the pipe piece 13 is embedded in the pot wall 11. In this way, the connection stability of the pipe piece 13 and the pot body 10 can be improved, and the pipe piece 13 and the pot body 10 are prevented from being separated after long-time heating, which can cause displacement of the temperature measuring piece 20 and reduce the temperature measuring accuracy of the pot 100.

[0106] The material of the pot body 10 can be one or more of aluminum, iron, stainless steel, titanium, ceramic, glass, etc., and the material of the pipe piece 13 can be one of stainless steel, titanium, ceramic, etc. The melting point of the material of the pipe piece 13 can be greater than the melting point of the material of the pot body 10, so as to ensure that the pipe piece 13 will not be damaged when the pot body 10 is formed.

[0107] When the pipe piece 13 is embedded in the pot wall 11, the distance d1 of the pipe piece 13 from the outer surface of the pot wall 11 can be in the range of 1mm≤d1≤2.5mm, and the distance d2 of the pipe piece 13 from the inner surface of the pot wall 11 can be in the range of 1mm≤d2≤3mm.

[0108] In combination with Figures 2 to 6 As shown, the pipe piece 13 can include a side segment 131 and a bottom segment 132, the side segment 131 is used to form the second channel 122, and the bottom segment 132 is used to form the first channel 121. The opening end of the pipe piece 13 is located at one end of the side segment 131 away from the bottom segment 132, and the temperature measuring piece 20 enters the side segment 131 through the opening end of the pipe piece 13 and extends into the bottom segment 132, i.e. into the first channel 121. The side segment 131 can be located entirely inside the side wall 112, as shown in Figure 2 , or part of the side segment 131 can be located outside the side wall 112, as shown in Figure 5 .

[0109] In one possible implementation, in combination with Figure 2 As shown, the side segment 131 can be located entirely inside the side wall 112, i.e. the second channel 122 is entirely located inside the side wall 112, so that the pipe piece 13 is entirely located inside the pot wall 11 after the pot 100 is formed, which can improve the appearance of the pot 100.

[0110] The open end of the pipe piece 13 can be located on the end face of the side edge 131 away from the bottom edge 132. Specifically, after the pipe piece 13 is embedded in the pot body wall 11, the open end of the pipe piece 13 can be located on the end face of the side wall 112 away from the bottom wall 111, that is, the first opening 1221 is located on the upper edge of the pot opening of the pot 100, so that the temperature measuring piece 20 can be conveniently inserted into the pipe piece 13 from the open end during installation, and the pot 100 is more beautiful.

[0111] Alternatively, the open end of the pipe piece 13 can be located on the outer wall surface of the side wall 112, that is, after the pipe piece 13 is embedded in the pot body wall 11, the open end of the pipe piece 13 is located on the outer wall surface of the side wall 112, that is, the first opening 1221 is located on the outer surface of the side wall 112 of the pot 100, so that the distance between the first opening 1221 and the first channel 121 can be relatively shortened, and the temperature measuring piece 20 can be conveniently inserted into the first channel 121 through the first opening 1221.

[0112] Alternatively, in another possible implementation, part of the side edge 131 is located in the side wall 112, that is, part of the second channel 122 is located in the side wall 112. Specifically, in combination with the side edge 131 shown in Figure 5 and Figure 6 The side edge 131 can include a body part 131a located inside the side wall 112 and an extension part 131b extending to the outside of the side wall 112. The extension part 131b can be used to fix the pipe piece 13 to the pot body 10, or the extension part 131b can be used to facilitate the fixing of the pipe piece 13 to the mold of the pot 100 when the pipe piece 13 is integrally formed with the pot body 10.

[0113] The extension part 131b can be part of the handle part, and when the handle is arranged, the extension part 131b can be hidden in the handle structure.

[0114] It should be understood that the extension part 131b is a part extending outside the pot body 10, and after the pipe piece 13 is integrally formed with the pot body 10, the extension part 131b can also be cut off. In this way, when the pipe piece 13 is fixed by the extension part 131b to realize the forming of the pipe piece 13 and the pot body 10, the excess part of the pipe piece 13 is cut off, which can improve the appearance of the pot 100 after forming.

[0115] As shown in Figure 5 The extension part 131b can extend from the end face of the side wall 112 away from the bottom wall 111 to the outside of the side wall 112, that is, the extension part 131b is located above the upper edge of the pot opening of the pot 100.

[0116] Alternatively, the extension part 131b can also extend from the side of the side wall 112 to the outside of the side wall 112, that is, the extension part 131b can be located on the outer surface of the side wall 112.

[0117] Referring to Figure 5 As shown in

[0118] In the embodiment of the present application, referring to Figure 7 As shown in

[0119] As shown in Figure 8 The extension portion 131b can include an inlet portion 1311, a second transition portion 1313, and a connecting portion 1312. The connecting portion 1312 is connected to the body portion 131a. To ensure the smoothness of the extension portion 131b, so as to facilitate the temperature measuring element 20 to extend into the bottom wall 111 through the extension portion 131b, the connecting portion 1312 can be parallel to the body portion 131a, that is, the connecting portion 1312 is smoothly connected to the body portion 131a.

[0120] The inlet portion 1311 and the connecting portion 1312 can be arranged at an angle. The body portion 131a is located in the side wall 112. As shown in Figure 5 and Figure 6 The body portion 131a and the connecting portion 1312 are vertically arranged, so that the inlet portion 1311 and the connecting portion 1312 are arranged at an angle. In this way, the extension portion 131b extends towards the horizontal direction, so that when the pipe piece 13 is fixed to the forming mold of the pot body 10 through the extension portion 131b, the connection between the extension portion 131b and the forming mold of the pot body 10 can be more easily achieved.

[0121] The inlet portion 1311 can be connected to the connecting portion 1312 through the second transition portion 1313, and the second transition portion 1313 can be arc-shaped. In this way, the temperature measuring element 20 can extend into the connecting portion 1312 through the inlet portion 1311, and then extend into the first channel 121, so as to achieve temperature measurement of the pot 100.

[0122] The arc of the first transition section 133 and / or the second transition section 1313 can be greater than or equal to 10 mm. When the arc of the first transition section 133 and the second transition section 1313 is too small, the temperature measuring piece 20 cannot pass through the first transition section 133 and the second transition section 1313 into the bottom edge section 132, so that the arc of the first transition section 133 and / or the second transition section 1313 is greater than or equal to 10 mm, which can ensure that the temperature measuring piece 20 can smoothly pass through the first transition section 133 and the second transition section 1313 and extend into the bottom edge section 132, that is, extend into the first channel 121.

[0123] Referring to Figure 9 As shown, the pipeline piece 13 can be provided with a blocking piece 134. Specifically, the blocking piece 134 can be arranged in the bottom edge section 132, and the blocking piece 134 can be used to block and limit the temperature measuring piece 20, so as to limit the extension position of the temperature measuring piece 20, so that the temperature measuring piece 20 extends to a specified position.

[0124] The blocking piece 134 can be a blocking plate or other structural piece. The blocking piece 134 arranged in the pipeline piece 13 can be one or multiple. Multiple blocking pieces 134 can be used to limit the same temperature measuring piece 20, or multiple blocking pieces 134 can be used to limit different temperature measuring pieces 20.

[0125] Figure 10 Another structure diagram of the pot pipeline piece provided by the embodiment of the present application is shown in FIG. 13; Figure 11 Another structure diagram of the pot pipeline piece provided by the embodiment of the present application is shown in FIG. 13; Figure 12 Another structure diagram of the pot pipeline piece provided by the embodiment of the present application is shown in FIG. 13; Figure 11 The top view of the pipeline piece is shown in FIG. 13.

[0126] In the embodiment, the pipeline 12 can include a second channel 122 and a first channel 121. The first channel 121 can be distributed along the diameter direction parallel to the bottom wall 111 of the pot body 10. Specifically, the first channel 121 can extend to the center of the bottom wall 111, or the first channel 121 can extend to other positions of the bottom wall 111. Part of the second channel 122 is arranged in the side wall 112, and the second channel 122 is in communication with the first channel 121, so that the temperature measuring piece 20 can pass through the side wall 112 of the pot body 10 and enter the bottom wall 111.

[0127] That is, as Figure 10As shown, the pipe piece 13 includes a side section 131 and a bottom section 132, the side section 131 and the bottom section 132 are communicated, and the bottom section 132 can only extend to the center of the bottom wall 111 of the pot body 10. The pipe piece 13 is embedded in the pot body wall 11, and the side section 131 can form a second channel 122 in the side wall 112, and the bottom section 132 can form a first channel 121 in the bottom wall 111.

[0128] Alternatively, each pipe 12 can also include two second channels 122 and a first channel 121, and the two second channels 122 are communicated with the first channel 121, as shown in Figures 1 to 3 That is, the first channel 121 penetrates the bottom wall 111 along the direction parallel to the diameter of the bottom wall 111, and is communicated with the two second channels 122 respectively. In this way, the temperature measuring piece 20 can extend into the first channel 121 from the first opening 1221 of any one of the second channels 122 to reach the specified position, which helps to improve the installation efficiency of the temperature measuring piece 20.

[0129] In addition, when the pipe 12 in the pot body wall 11 is formed by embedding the pipe piece 13, each pipe 12 includes two second channels 122 and a first channel 121, and the two second channels 122 are communicated with the first channel 121 respectively. That is, the pipe piece 13 can include two side sections 131 and a bottom section 132, and the pipe piece 13 can be fixed in the mold of the pot body 10 through the side sections 131. The arrangement of the two side sections 131 can facilitate the arrangement of the pipe piece 13 in the mold of the pot body 10, improve the stability of the pipe piece 13 during the forming process, ensure the accuracy of the arrangement position of the pipe piece 13, and improve the qualified rate of the pot 100.

[0130] Among them, one of the second channels 122 can be located on one side of the other second channel 122, or among them, the second channel 122 can be located on the opposite side of the other second channel 122, when the two second channels 122 are oppositely arranged (combined with Figure 3 、 Figure 5 and Figure 6 As shown, the first channel 121 is arranged along the diameter direction of the bottom wall 111, and the first channel 121 passes through the center of the bottom wall 111, so that the temperature measuring piece 20 can extend into the first channel 121 along any one of the second channels 122, which facilitates the assembly and arrangement of the temperature measuring piece 20.

[0131] Specifically, as shown in Figure 6 The pipe piece 13 can include two side sections 131 and a bottom section 132, and the two side sections 131 are communicated with the bottom section 132, and as shown in Figure 5As shown, the pipe piece 13 is embedded in the pot wall 11, and the two side edge segments 131 can form two second channels 122 in the side wall 112, and the bottom edge segment 132 can form a first channel 121 in the bottom wall 111.

[0132] When one of the second channels 122 is located at the opposite side of the other second channel 122, that is, the two second channels 122 are oppositely arranged, in combination with Figure 6 As shown, the pipe piece 13 also includes two oppositely arranged side edge segments 131 and a bottom edge segment 132, so that the pipe piece 13 is easy to process into an integral whole, and it is convenient to form the above-mentioned one pipe 12 in the pot wall 11 through one pipe piece 13.

[0133] In the embodiment of the present application, a plurality of pipes 12 can be arranged in the pot wall 11. Specifically, each pipe 12 includes a first channel 121, a second channel 122, or a first channel 121 and two second channels 122. In this way, a plurality of temperature measuring pieces 20 can be arranged in the interior of the pot wall 11, and multi-point temperature measurement of the bottom of the pot 100 can be realized, thereby improving the accuracy of temperature measurement of the pot 100.

[0134] In addition, the first channels 121 in the plurality of pipes 12 can also extend to different positions in the bottom wall 111, thereby expanding the temperature measurement range of the pot 100, and at the same time, different temperature measurement functions can be realized according to different use scenarios, which helps to improve the functionality of the pot 100.

[0135] As shown in FIG. 1, a plurality of pipe pieces 13 can be embedded in the pot wall 11 to form a plurality of pipes 12. Figure 11 and Figure 12 As shown, taking the case that the pipe piece 13 includes two as an example, one of the pipe pieces 13b includes a bottom edge segment 132 and a side edge segment 131, and the other pipe piece 13a includes a bottom edge segment 132 and two oppositely arranged side edge segments 131. By embedding the two pipe pieces in the pot wall 11, a plurality of pipes 12 can be formed in the pot wall 11, one of which includes a first channel 121 and a second channel 122, and the other of which includes a first channel 121 and two second channels 122.

[0136] As shown in FIG. 1, any two or more of the plurality of pipes 12 are connected, and as shown in Figure 11 and Figure 12 As shown, taking the case that the pipe piece 13 includes two as an example, the two pipe pieces 13 can be connected, and by embedding the two connected pipe pieces 13 in the pot wall 11, two connected pipes 12 are formed in the pot wall 11, so that the temperature measuring ends of the two temperature measuring pieces 20 can be arranged at the same position through the two pipes 12.

[0137] Alternatively, the plurality of pipes 12 can be mutually independent, so that the temperature measuring ends of the different temperature measuring members 20 can be arranged at different positions through the plurality of pipes 12.

[0138] Figure 13 is another structural schematic view of a pipe member provided by an embodiment of the present application; Figure 14 is Figure 13 is an enlarged view of a partial structure of Figure 15 is a sectional view of a pipe member provided by an embodiment of the present application.

[0139] Referring to Figure 13 and Figure 14 , in the embodiment of the present application, the outer wall of at least part of the pipe member 13 has a reinforcing portion 135 protruding outward, which can improve the strength of the pipe member 13 and reduce the probability of deformation of the pipe member 13 under long-term high-temperature use.

[0140] In addition, when the pipe member 13 is integrally embedded in the pot wall 11 when the pot body 10 is formed, the arrangement of the reinforcing portion 135 enhances the strength of the pipe member 13, which can reduce the deformation of the pipe member 13 in the process of forming the pot body 10 by pressure casting or high-temperature pouring, and improve the pass rate of forming the pot 100. The reinforcing portion 135 can be located on the side edge segment 131 of the pipe member 13.

[0141] Referring to Figure 14 , the reinforcing portion 135 can be a square-shaped protrusion, wherein the width d of the reinforcing portion 135, i.e., the length of the outward protrusion, is 0.3-1mm. The height h of the reinforcing rib can be 0.5-1.5mm. When there are a plurality of reinforcing portions 135, the distance L between the reinforcing portions 135 is 1-10mm, so that the reinforcing portions 135 can effectively improve the strength of the pipe member 13.

[0142] The pipe member 13 can also be provided with a fixing member 136, which is used for fixedly connecting with a forming mold of the pot body 10, so that the pipe member 13 is fixed with the mold, avoiding the movement of the pipe member 13 in the mold during the forming process, especially for Figure 10 the pipe member 13 including only one side edge segment 131, the arrangement of the fixing member 136 can ensure that the pipe member 13 can be accurately embedded in the pot wall 11, improving the pass rate of forming the pot 100.

[0143] The fixing member 136 can be a fixing column, and a limiting hole can be arranged on the mold, and the fixing member 136 can be inserted into the limiting hole to fix the pipe member 13 on the mold.

[0144] In order to ensure the connection firmness of the fixing member 136, the diameter of the fixing member 136 can be 0.3-1.5 mm. In order to facilitate the limiting cooperation between the fixing member 136 and the limiting hole and to strengthen the cooperation firmness therebetween, the height of the fixing member 136, i.e. the length of the fixing member 136 extending to the limiting hole, can be 0.5-3 mm.

[0145] As shown in the embodiment of the present application, Figure 15 The inner wall of the pipe member 13 can be a cylinder or an elliptical cylinder or other cylindrical structure, and the inner wall surface of the cylinder or the cylindrical structure is relatively smooth, which can facilitate the temperature measuring member 20 to extend into and move in the pipe member 13. Specifically, the inner diameter of the pipe member 13 can be 1.8-2.5 mm.

[0146] The pipe member 13 can be formed by welding or casting, and the pipe member 13 can be prepared by using a strip welding method, so that the wall thickness and the hole diameter of the pipe member 13 have good consistency. The wall thickness of the pipe member 13 can be in the range of 0.1 mm≤a≤0.5 mm.

[0147] The pot 100 provided by the embodiment of the present application comprises a pot body 10, and a plurality of pipes 12 for accommodating a temperature measuring member 20 are arranged inside a pot wall 11 of the pot body 10. The pot wall 11 comprises a bottom wall 111 and a side wall 112 surrounding the bottom wall 111, and the pipe 12 comprises a first channel 121 and a second channel 122 connected in communication. The first channel 121 is located in the bottom wall 111, and at least part of the second channel 122 is located in the side wall 112. The second channel 122 has a first opening 1221 at an end away from the first channel 121, and the first opening 1221 is used for the temperature measuring member 20 to pass through and enter the pipe 12. That is, the pipe 12 for arranging the temperature measuring member 20 is located inside the pot wall 11, and the temperature measuring member 20 can extend into the bottom wall 111 of the pot body 10 through the pipe 12. The temperature measuring member 20 can accurately measure the temperature at the bottom of the pot body 10 without damaging the outer surface of the bottom of the pot body 10, so as to ensure the inductive heating effect of the pot 100 and effectively improve the accuracy of temperature measurement of the pot 100.

[0148] Embodiment two

[0149] The embodiment of the present application provides a manufacturing method of a pot, which is used for manufacturing the pot 100 in the above-mentioned embodiment one. Specifically, the method comprises the following steps.

[0150] S101: providing a pipe member, an upper mold and a lower mold corresponding to the upper mold. The upper mold and the lower mold each comprise a bottom surface and a side surface surrounding the bottom surface. The pipe member comprises a side edge segment and a bottom edge segment connected in communication, and the side edge segment has a second opening at an end away from the bottom edge segment.

[0151] Specifically, the upper mold and the lower mold can be matched with the shape of the pot body 10, and both of them can be hemispherical with cavities inside. The pipe member 13 can be a tubular structure made of stainless steel, titanium, ceramic or other materials with a melting point higher than that of the pot 100.

[0152] S102: The upper mold and the lower mold are closed, leaving a gap between them to form a casting gap, and the pipe member is arranged inside the casting gap. At least part of the side edge of the pipe member corresponds to the side surface of the upper mold and the lower mold, the bottom edge corresponds to the bottom surface of the upper mold and the lower mold, and the second opening is exposed outside the casting gap.

[0153] That is, when the pipe member 13 is arranged in the casting gap, at least part of the side edge 131 of the pipe member 13 is located opposite to the side surface of the upper mold and the lower mold, the bottom edge 132 of the pipe member 13 is located opposite to the bottom surface of the upper mold and the lower mold, and the second opening on the side edge 131 is exposed outside the casting gap and will not be blocked. After forming, the temperature measuring member 20 can enter the pipe member 13 from the second opening.

[0154] S103: Casting forming and demolding.

[0155] Specifically, casting can be performed by casting or pressure casting. For example, in the casting gap between the upper mold and the lower mold, the pouring liquid in the casting gap between the upper mold and the lower mold is formed into the pot wall 11 of the pot 10. Specifically, the pouring liquid between the two side surfaces of the upper mold and the lower mold is formed into the side wall 112 of the pot 10, and the pouring liquid between the two bottom surfaces of the upper mold and the lower mold is formed into the bottom wall 111 of the pot 10.

[0156] Since the pipe member 13 is inside the casting gap, after the pouring liquid in the casting gap is formed, the pipe member 13 will be embedded inside the pot wall 11, thereby forming a pipeline 12 inside the pot wall 11. Specifically, the side edge 131 of the pipe member 13 will form a second channel 122, and at least part of the second channel 122 will be located in the side wall 112 of the pot wall 11. The bottom edge 132 of the pipe member 13 will form a first channel 121, and the first channel 121 will be located in the bottom wall 111 of the pot wall 11. The second channel 122 has a second opening at the end away from the first channel 121.

[0157] The temperature measuring member 20 can pass through the second opening into the pipe member 13, i.e. into the pipeline 12 and extend to a specified position in the first channel 121. In this way, the temperature measuring member 20 can extend to the bottom of the pot 10 to measure the temperature of the bottom of the pot 10 and improve the accuracy of temperature measurement.

[0158] And since the pipeline 12 formed by the pipe fitting 13 is located inside the pot wall 11, the first channel 121 corresponding to the bottom of the pot 10 is also located inside the bottom wall 111 of the pot 10, so that the pipeline 12 for accommodating the temperature measuring element 20 will not damage the outer surface of the bottom of the pot 10, avoiding the influence of blocking the magnetic circuit of the pot 100, ensuring the effect of induction heating of the pot 100, thereby effectively improving the accuracy of temperature measurement of the pot 100.

[0159] In addition, after the temperature measuring element 20 extends into the first channel 121, the temperature measuring element 20 is located inside the pot wall 11. Compared with the existing method of slotting at the bottom of the pot 10, there is no need to additionally set a slot cover or the like for hiding the temperature measuring element 20 by welding or the like. It can avoid problems such as deformation and falling off of the slot cover due to long-term heating, improve the use stability and service life of the pot 100.

[0160] Among them, the material of the casting liquid forming the pot 100, and the material, size and the like of the pipe fitting 13 can be referred to in Example 1, which will not be repeated in this embodiment.

[0161] In the embodiment of the application, referring to Example 1, the side edge segment 131 and the bottom edge segment 132 of the pipe fitting 13 can be communicated through the first transition segment 133, and the first transition segment 133 can be arc-shaped, so that the temperature measuring element 20 can be conveniently extended into the bottom edge segment 132 from the side edge segment 131, and the temperature measuring element 20 can be conveniently extended into the first channel 121.

[0162] In combination with Example 1, the pipe fitting 13 can include one side edge segment 131 and one bottom edge segment 132, so that after the pipe fitting 13 is embedded in the pot wall 11, the side edge segment 131 can form a second channel 122 in the side wall 112 of the pot wall 11, and the bottom edge segment 132 can form a first channel 121 in the bottom wall 111 of the pot wall 11. The first channel 121 can extend to the center of the bottom wall 111, or the first channel 121 can extend to other positions of the bottom wall 111.

[0163] Alternatively, the pipe fitting 13 can include two side edge segments 131 and one bottom edge segment 132. When the pipe fitting 13 is arranged in the casting gap between the upper mold and the lower mold, the pipe fitting 13 can be fixed with the upper mold and / or the lower mold through the side edge segment 131. The two side edge segments 131 can improve the stability of the pipe fitting 13 fixed with the upper mold and / or the lower mold, facilitate fixation, and ensure the stability of the arrangement position of the pipe fitting 13.

[0164] After the pipe piece 13 is embedded in the pot body 10, the bottom edge segment 132 can form a first channel 121 in the bottom wall 111, and the two side edge segments 131 can form two second channels 122 in the side wall 112, and the two second channels 122 are in communication with the first channel 121.

[0165] One of the side edge segments 131 can be located on one side of the other side edge segment 131, or the two side edge segments 131 can be oppositely arranged. When the two side edge segments 131 are oppositely arranged, the pipe piece 13 is easy to process, and it is convenient to form one pipe 12 inside the inner wall of the pot body 10 by one pipe piece 13,

[0166] In the method, the pipe piece 13 is arranged in the casting gap. The pipe piece 13 can be multiple, and each pipe piece 13 can include one bottom edge segment 132, one side edge segment 131, or one bottom edge segment 132 and two side edge segments 131. In this way, after the above method is used for forming, multiple pipes 12 can be formed inside the pot body wall 11, and multiple temperature measuring pieces 20 can be arranged inside the pot body wall 11, so that multi-point temperature measurement of the bottom of the pot 100 is realized, and the accuracy of temperature measurement of the pot 100 is improved.

[0167] In addition, the first channel 121 in the multiple pipes 12 can also extend to different positions in the bottom wall 111, or the temperature measuring piece 20 can be located at different positions in the first channel 121, so as to expand the temperature measurement range of the pot 100, and also realize different temperature measurement functions according to different use scenes, which helps to improve the functionality of the pot 100.

[0168] When multiple pipe pieces 13 are arranged in the pot body 10, any two or more pipe pieces 13 can be in communication, so that the temperature measuring ends of multiple temperature measuring pieces 20 can be arranged at the same position through the pipe pieces 13.

[0169] Alternatively, the multiple pipe pieces 13 can not be in communication, so that the temperature measuring ends of different temperature measuring pieces 20 can be arranged at different positions through the multiple pipe pieces 13.

[0170] In the embodiment of the application, in step S102, the pipe piece 13 is arranged in the casting gap, and at least part of the side edge segment 131 corresponds to the side surface of the upper mold and the lower mold. Specifically, in one possible implementation, all the side edge segments 131 can correspond to the side surface of the upper mold and the lower mold, that is, after casting and forming, the second channels 122 formed by the side edge segments 131 are all located in the side wall 112.

[0171] The second opening is located on one end of the side edge section 131 away from the bottom edge section 132 and is exposed outside the casting cavity. Specifically, the second opening can be located on an end face of the one end of the casting cavity away from the bottom face of the upper mold and the lower mold. Thus, after casting, the second opening is located on an end face of the side wall 112 away from the bottom wall 111, i.e., on the upper edge of the pot opening of the pot 10.

[0172] Alternatively, the second opening can also be located on the side face of the lower mold. After casting, the second opening is located on the outer surface of the side wall 112 of the pot 10.

[0173] In another possible implementation, part of the side edge section 131 can correspond to the side face of the upper mold and the lower mold. Specifically, in step S102, the pipe member 13 is arranged in the casting cavity, including:

[0174] The body part corresponds to the side face of the upper mold and the lower mold, and the extension part extends out of the casting cavity.

[0175] Thus, after casting, part of the second channel 122 is located in the side wall 112, and part of the second channel 122 extends out of the side wall 112. The extension part 131b extending out of the casting cavity can be used to be fixed with the upper mold and / or the lower mold, facilitating the fixation of the pipe member 13.

[0176] The extension part 131b can extend out of the casting cavity from an end face of the one end of the casting cavity away from the bottom face. Thus, after casting, the extension part 131b is located above the upper edge of the pot opening of the pot 100. Alternatively, the extension part 131b can extend out of the casting cavity from the side face of the lower mold (e.g., a hole is formed in the lower mold for the extension part 131b to pass through). After casting, the extension part 131b can be located on the outer surface of the side wall 112.

[0177] In one possible implementation, the pot 100 can further include a temperature measuring member 20. After step S103, the method further includes:

[0178] The temperature measuring member extends into the pipe member through the second opening;

[0179] The second opening is sealed by the sealing member.

[0180] That is, the temperature measuring member 20 enters the pipe member 13 through the second opening on the extension part 131b, and thus extends into the pipe 12 and can extend into the first channel 121, achieving the detection of the temperature of the bottom of the pot 10.

[0181] After the temperature measuring member 20 extends into the pipe 12 inside the inner wall of the pot 10, the second opening can be sealed by the sealing member 30. Thus, the oil fume and water vapor can be prevented from entering the pipe member 13 through the second opening, and the temperature measuring member 20 can be prevented from being damaged.

[0182] As shown in Embodiment One, in the present embodiment, the extension 131b can also include an inlet section 1311, a second transition section 1313, and a connecting section 1312. The connecting section 1312 is connected to the body section 131a. To ensure the smoothness of the extension 131b, so as to facilitate the temperature measuring member 20 extending into the bottom wall 111 through the extension 131b, the connecting section 1312 can be parallel to the body section 131a, i.e., the connecting section 1312 is smoothly connected to the body section 131a.

[0183] The inlet section 1311 and the connecting section 1312 can be arranged at an angle, so that the extension 131b extends towards the horizontal direction, which can facilitate the connection of the extension 131b to the upper mold and / or the lower mold.

[0184] The inlet section 1311 can be connected to the connecting section 1312 through the second transition section 1313, and the second transition section 1313 can be arc-shaped, which can facilitate the temperature measuring member 20 extending into the connecting section 1312 through the inlet section 1311, and then extending into the first channel 121, so as to realize the temperature measurement of the pot 100.

[0185] In another possible implementation, after step S103, the method further includes:

[0186] cutting off the extension to form a third opening on the pipe member;

[0187] extending the temperature measuring member into the pipe member through the third opening;

[0188] sealing the third opening by the sealing member.

[0189] After step S103, the molded pot body is taken out, and then the extension 131b extending outside the pot body 10 is cut off to form a third opening on the pipe member 13. The temperature measuring member 20 is extended into the pipe member through the third opening, and the third opening is sealed by the sealing member 30 to form the pot 100.

[0190] In this way, the extension 131b extending outside the casting gap is cut off, i.e., the excess part of the pipe member 13 is cut off at the same time when the pipe member 13 is fixed to the pot body 10 through the extension 131b, which can improve the appearance of the molded pot 100.

[0191] It should be understood that when the extension 131b is cut off, a third opening is formed on the pipe member 13, and the third opening is located on the end face of the side wall 112 away from the bottom wall 111, i.e., on the upper edge of the pot opening of the pot body 10. Alternatively, the second opening is located on the outer surface of the side wall 112 of the pot body 10.

[0192] The pipe piece 13 can further be provided with a blocking piece 134, and the blocking piece 134 can be arranged in the bottom edge section 132. The blocking piece 134 is used to block and limit the temperature measuring piece 20, so as to limit the insertion position of the temperature measuring piece 20, and make the temperature measuring piece 20 inserted to a specified position. The structure of the blocking piece 134 can refer to the first embodiment, and will not be described herein.

[0193] In the embodiment, the upper die and / or the lower die can be provided with a first groove on the opposite side, and the first groove can be matched with the extension part 131b to fix the pipe piece 13 in the casting gap.

[0194] Specifically, the pipe piece 13 can be a cylindrical pipe body, and the outer wall of the extension part 131b can also be cylindrical. The first groove can be a semicircular groove arranged on the opposite side of the upper die and the lower die and matched with the extension part 131b. The extension part 131b can be inserted into the first groove and matched with the first groove, so that the pipe piece 13 can be fixed in the casting gap through the first groove.

[0195] Correspondingly, the lower die and the upper die can also be provided with a second groove on the opposite side, and the second groove can be matched with the extension part 131b. The extension part 131b can be inserted into the second groove and matched with the second groove, so that the pipe piece 13 can be fixed in the casting gap through the second groove, and the stability of the pipe piece 13 in the casting gap is further ensured.

[0196] The pipe piece 13 can be provided with a first fixing part on one side of the two sides opposite to the first groove, and the other side can be provided with a first limiting hole matched with the first fixing part.

[0197] Specifically, the side opposite to the first groove of the pipe piece 13 can be provided with a first fixing part protruding towards the first groove, and the first groove can be provided with a first limiting hole matched with the first fixing part. The pipe piece 13 can be fixed in the first groove through the cooperation of the first fixing part and the first limiting hole, and the displacement of the pipe piece 13 in the first groove can be limited. Especially when the pipe piece 13 only includes one side edge section 131 and one bottom edge section 132, the first fixing part and the first limiting hole (and / or the second fixing part and the second limiting hole) can effectively fix the pipe piece 13, further improve the setting stability of the pipe piece 13 in the casting gap, and help to improve the qualified rate of the pot 100.

[0198] Correspondingly, the two sides of the pipe piece 13 opposite to the second groove, one of which has the second fixing piece, and the other of which has the second limiting hole matched with the second fixing piece. Specifically, the side of the pipe piece 13 opposite to the second groove can have the second fixing piece protruding towards the second groove, the second groove can have the second limiting hole matched with the second fixing piece, and the pipe piece 13 can be fixed in the second groove through the cooperation of the second fixing piece and the second limiting hole, so as to limit the displacement of the pipe piece 13 in the second groove and further improve the setting stability of the pipe piece 13 in the casting gap.

The reinforcing part 135 can improve the strength of the pipe piece 13, reduce the probability of deformation of the pipe piece 13 under long-time high-temperature use, and further reduce the deformation of the pipe piece 13 in the process of forming the pot 100 by die casting or high-temperature pouring, thereby improving the qualified rate of forming the pot 100. The reinforcing part 135 can be located on the side edge segment 131 of the pipe piece 13.

[0201] The specific structure, size and the like of the reinforcing part 135 can refer to Embodiment One, which will not be described herein again.
