Description

[Technical field]

[0001] The utility model relates to the technical field of kitchen appliances, in particular to an electric stew pot. [Background technology]

[0002] The electric stew pot includes a pot body, an outer pot installed in the pot body and a ceramic liner placed in the outer pot. A heating device is provided at the bottom of the outer pot. When stewing food, the heating device heats the water in the outer pot, and the hot water transfers the heat to the ceramic liner, so that the food in the ceramic liner is evenly and gently stewed in water. In this type of cooking equipment, the outer pot is often made of PP plastic with a temperature resistance of about 120°, and the mounting part of the heating device is fixedly installed on the fixed position of the bottom wall of the outer pot by fasteners such as screws, and a sealing ring is provided between the heating device and the bottom wall of the outer pot. In the heating device assembly structure disclosed in the relevant prior art, in order to separate the heat of the heating device and the bottom wall of the outer pot, a plastic pad is usually placed between the heating device and the bottom wall of the outer pot for heat insulation. However, when the water in the outer pot is boiled dry and the power is not turned off in time, the electric stew pot will dry burn. Especially when the dry-burning time is long, the local temperature of the heating device rises, and the heat will be directly transferred to the bottom wall of the outer pot through the screws. Due to the temperature resistance limit of the outer pot material, the heated screws will have the risk of melting and deforming the fixed position, causing the heating device to loosen and the sealing ring to fail, which in turn causes the outer pot to leak, posing a safety hazard to the electric stew pot.

The heat insulating member is arranged between the outer pot and the mounting portion to separate the outer pot and the mounting portion, and the mounting portion is fixed on the heat insulating member by a first fastener. In this way, when the heating device causes the mounting portion to heat up due to the dry burning of the outer pot, the heat of the mounting portion will be transferred to the heat insulating member and the first fastener. Since the heat insulating member has the effect of blocking the heat flow transfer, the heat insulating member can be used to separate the outer pot and the mounting portion, and the heat insulating member can be used to block the heat transfer from the mounting portion to the outer pot, so as to reduce the temperature rise of the outer pot; in addition, since the first fastener is fixed on the heat insulating member, the heat insulating member can also be used to prevent the first fastener from contacting the outer pot, that is, the heat insulating member can also block the heat transfer from the first fastener to the outer pot, thereby greatly reducing the heat transferred from the heating device to the bottom wall of the outer pot, so as to avoid deformation of the bottom wall of the outer pot, thereby reducing the risk of water leakage caused by failure of the sealing ring.

[0017] 2. A fixing groove is provided on the outer side of the bottom wall of the outer pot, and the heat insulating member includes a heat insulating rod and a heat insulating head provided at one end of the heat insulating rod, the heat insulating head is vertically limited in the fixing groove, and the other end of the heat insulating rod extends out of the fixing groove and abuts against the mounting portion.

[0018] 3. The groove wall of the fixed groove includes a first groove wall extending vertically and a second groove wall extending horizontally. The first groove wall is provided with a notch, and the second groove wall is provided with a through hole for the heat insulation rod to pass through. The through hole is connected to the notch, and the heat insulation head is inserted into the fixed groove through the notch.

This design can save the assembly steps of the limiting rib and the bottom wall of the outer pot, thereby simplifying the assembly steps of the pot body; in addition, the integral molding method can also enhance the connection reliability between the limiting rib and the bottom wall of the outer pot, thereby ensuring the vertical limiting reliability of the insulation head and preventing the insulation head from falling off the bottom wall of the outer pot.

[0020] 5. The heat insulating member is fixed to the bottom wall of the outer pot by the second fastener, and the second fastener is separated from the first fastener. With such a design, the heat insulating member can be fixed to the bottom wall of the outer pot by the second fastener, and the second fastener can be separated from the first fastener to prevent the heat of the first fastener from being transferred to the second fastener, thereby preventing the second fastener from transferring the heat of the first fastener to the bottom wall of the outer pot.

[0021] 6. The heat insulating member includes a heat insulating rod and a heat insulating head protruding from the outer peripheral side of one end of the heat insulating rod, the heat insulating head is fixed to the bottom wall of the outer pot by a second fastener, and the heat insulating rod abuts against the mounting portion and is connected to the first fastener. Such a design can not only increase the contact area between the heat insulating member and the bottom wall of the outer pot by providing the heat insulating head, thereby improving the support reliability of the heating device, but also facilitate the second fastener to fix the heat insulating member on the bottom wall of the outer pot, thereby reducing the difficulty of installing the second fastener, and at the same time prevent the first fastener from contacting the second fastener.

[0022] 7. A notch is provided at the edge of the mounting portion, and the heat insulating member includes a heat insulating sleeve provided through the notch, and two heat insulating sheets provided at intervals on the outer peripheral side of the heat insulating sleeve, and the portion of the mounting portion surrounding the notch is clamped between the two heat insulating sheets, and the first fastener is provided through the heat insulating sleeve.

A heat dissipation gap is formed between two adjacent reinforcing ribs, and the portion of the mounting portion surrounding the gap is clamped between the reinforcing ribs of the two heat insulation sheets. This design can reduce the contact area between the heat insulation sheet and the mounting portion to reduce heat transfer. At the same time, the heat of the mounting portion and the heat insulation sheet can also be dissipated into the air through the heat dissipation gap to further reduce the temperature rise of the heat insulation component.

[0024] 9. The first fastener is a screw, and the thermal insulation member is provided with a threaded hole that matches the screw. Such a design can not only ensure the connection reliability between the first fastener and the thermal insulation member, but also simplify the assembly difficulty of the first fastener and the thermal insulation member.

[Specific implementation method]

[0036] The utility model provides an electric stew pot, comprising a pot body, an outer pot installed in the pot body and a ceramic inner pot placed in the outer pot, a heating device is provided at the bottom of the outer pot, the pot body also comprises a heat insulating member fixed on the bottom wall of the outer pot, the heating device comprises a mounting portion, the heat insulating member is arranged between the outer pot and the mounting portion to separate the outer pot from the mounting portion, and the mounting portion is fixed on the heat insulating member by a first fastener.

[0037] The pot body in the utility model also includes a heat insulating member fixed on the bottom wall of the outer pot, and the heating device includes a mounting portion, the heat insulating member is arranged between the outer pot and the mounting portion to separate the outer pot and the mounting portion, and the mounting portion is fixed on the heat insulating member by a first fastener. In this way, when the heating device causes the mounting portion to heat up due to the dry burning of the outer pot, the heat of the mounting portion will be transferred to the heat insulating member and the first fastener. Since the heat insulating member has the effect of blocking the heat flow transfer, the outer pot and the mounting portion are separated by the heat insulating member, and the heat transfer from the mounting portion to the outer pot can be blocked by the heat insulating member to reduce the temperature rise of the outer pot; in addition, since the first fastener is fixed on the heat insulating member, the first fastener can also be prevented from contacting the outer pot through the heat insulating member, that is, the heat transfer from the first fastener to the outer pot is also blocked by the heat insulating member, thereby greatly reducing the heat transferred from the heating device to the bottom wall of the outer pot, so as to avoid deformation of the bottom wall of the outer pot, thereby reducing the risk of water leakage caused by failure of the sealing ring.

[0038] The technical scheme of the embodiment of the utility model is explained and illustrated below in conjunction with the drawings of the embodiment of the utility model, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without making creative work all belong to the protection scope of the utility model.

[0039] Embodiment 1

[0040] like Figures 1 to 5As shown, the electric stew pot in this embodiment includes a pot body 100, an outer pot 200 installed in the pot body 100 and a ceramic liner (not shown in the figure) placed in the outer pot 200. A heating device 300 is provided at the bottom of the outer pot 200. In order to reduce the heat transfer from the heating device 300 to the bottom wall of the outer pot, a plastic pad is usually placed between the heating device 300 and the bottom wall of the outer pot for heat insulation. The screws penetrate the heating device and the plastic pad and are locked in the fixed position of the bottom wall of the outer pot. However, when the water in the outer pot is dried up and the power is not turned off in time, the electric stew pot will dry burn. In particular, when the dry burning time is long, the local temperature of the heating device 300 rises, and its heat will be directly transferred to the bottom wall of the outer pot through the screws. Due to the temperature resistance limit of the material of the outer pot 200, the heated screws will have the risk of melting and deforming the fixed position, resulting in the loosening of the reinforcing device 300, causing the sealing ring to fail, and then causing the outer pot to leak, so that the electric stew pot has a safety hazard.

[0041] In order to solve the above technical problems, the pot body 100 in this embodiment also includes a heat insulating member 400 fixed on the bottom wall of the outer pot 200, the heating device 300 includes a mounting portion 310, the heat insulating member 400 is arranged between the outer pot 200 and the mounting portion 310 to separate the outer pot 200 from the mounting portion 310, and the mounting portion 310 is fixed to the heat insulating member 400 by a first fastener (not shown in the figure). When the electric stew pot is in use, when the heating device 300 causes the mounting portion 310 to heat up due to the dry burning of the outer pot 200, the heat of the mounting portion 310 will be transferred to the thermal insulation 400 and the first fastener. Since the thermal insulation 400 has the effect of blocking the transfer of heat flow, the outer pot 200 and the mounting portion 310 are separated by the thermal insulation 400, and the heat transfer from the mounting portion 310 to the outer pot 200 can be blocked by the thermal insulation 400 to reduce the temperature rise of the outer pot 200; in addition, since the first fastener is fixed on the thermal insulation 400, the thermal insulation 400 can also prevent the first fastener from contacting the outer pot 200, that is, the thermal insulation 400 also blocks the heat transfer from the first fastener to the outer pot, thereby greatly reducing the heat transferred from the heating device 300 to the bottom wall of the outer pot, so as to avoid deformation of the bottom wall of the outer pot, thereby reducing the risk of water leakage due to failure of the sealing ring.

[0042] Specifically, in this embodiment, a fixing groove 210 is provided on the outer side of the bottom wall of the outer pot 200, and the heat insulation member 400 includes a heat insulation rod 410 and a heat insulation head 420 provided at one end of the heat insulation rod 410, the outer diameter of the heat insulation head 420 is larger than the outer diameter of the heat insulation rod 410, and the heat insulation head 420 and the heat insulation rod 410 are integrally formed, and the heat insulation head 420 is vertically limited in the fixing groove 210, and the other end of the heat insulation rod 410 extends out of the fixing groove 210 and abuts against the mounting portion 310 to support the mounting portion 310, so that the mounting portion 310 is separated from the bottom wall of the outer pot, and a connecting hole 311 is provided on the mounting portion 310, and the first fastener passes through the connecting hole 311 and is locked on the heat insulation rod 410, so as to fix the heating device 300 on the heat insulation member 400. In addition, in this embodiment, the vertical limitation of the thermal insulation head 420 is achieved by the fixed groove 210 to realize the vertical limitation of the thermal insulation component 400. The assembly is simple and convenient, and there is no need to open a hole in the outer bottom wall of the pot to connect it with the thermal insulation head, and there is no need to add a sealing ring at the opening to ensure sealing, thereby simplifying the structure of the pot body.

[0043] The groove wall of the fixed groove 210 in this embodiment includes a first groove wall 211 extending vertically and a second groove wall 212 extending laterally. The second groove wall 212 is located on the side of the insulation head 420 away from the bottom wall of the outer pot, and the first groove wall 211 is arranged around the second groove wall 212. The first groove wall 211 extends vertically and is connected between the second groove wall 212 and the bottom wall of the outer pot. The first groove wall 211, the second groove wall 212 and the outer side of the bottom wall of the outer pot surround the fixed groove 210, and the insulation head 420 is confined between the second groove wall 212 and the bottom wall of the outer pot, thereby realizing the vertical limitation of the insulation head 420 in the fixed groove 210.

[0044] In order to facilitate the smooth installation of the heat insulation head 420 into the fixing groove 210, a notch 2110 is provided on the first groove wall 211, and a through hole 2120 is provided on the second groove wall 212 for the heat insulation rod 410 to pass through. The aperture of the through hole 2120 is between the outer diameter of the heat insulation rod 410 and the outer diameter of the heat insulation head 420, that is, the heat insulation head 420 cannot pass through the through hole 2120, so that the lower limit of the heat insulation head 420 can be achieved through the second groove wall 212, and the through hole 2120 extends to the second groove wall 212. 2 corresponds to one side edge of the notch 2110, so that the notch 2110 is connected with the through hole 2120. In this way, when assembling the heat insulating member 400, when the heat insulating head 420 is inserted into the fixing groove 210 through the notch 2110, the heat insulating rod 410 can also be smoothly passed through the through hole 2120 through the notch 2110, and no tool is required for assembly, so the assembly is simple and convenient; in addition, the heat insulating member 400 can be detachably installed on the bottom wall of the outer pot, which is convenient for the subsequent separate replacement of the heat insulating member 400.

[0045] In order to enhance the vertical limiting reliability of the fixing groove 210 on the insulation head 420, in the present embodiment, the outer side of the bottom wall of the outer pot 200 is integrally formed with limiting ribs, and the limiting ribs and the bottom wall of the outer pot form the fixing groove 210, that is, the limiting ribs include the above-mentioned first groove wall 211 and the second groove wall 212. Such a design can omit the assembly steps of the limiting ribs and the bottom wall of the outer pot, as well as the assembly steps of the first groove wall 211 and the second groove wall 212, thereby simplifying the assembly steps of the pot body; in addition, the one-piece molding method can also enhance the connection reliability between the limiting ribs and the bottom wall of the outer pot, thereby ensuring the vertical limiting reliability of the insulation head 420 and preventing the insulation head 420 from falling off the bottom wall of the outer pot.

[0046] The first fastener in this embodiment is preferably a screw, and a threaded hole matching the screw is provided on the heat insulating rod 410. Such a design can ensure the connection reliability between the first fastener and the heat insulating member 400 and simplify the assembly difficulty of the first fastener and the heat insulating member 400.

[0047] In order to enhance the structural strength of the bottom wall of the outer pot, part of the bottom wall of the outer pot 200 is recessed upward to form a sink 230, and the limiting ribs are integrally formed in the sink 230, that is, the first groove wall 211 is connected to the bottom wall of the sink 230 and the side wall of the sink 230, so as to enhance the structural strength of the limiting ribs. At the same time, the design of the sink 230 also enhances the structural strength of the bottom wall of the outer pot. Finally, such a design can also increase the overall height of the thermal insulation component 400 to increase the thermal insulation effect of the thermal insulation component 400.

[0048] Finally, in order to improve the thermal efficiency of the electric stew pot, in this embodiment, a through hole 220 is provided at the bottom of the outer pot 200, and the heating device 300 also includes a heating part 320, which is a PTC heating element or an electric heating tube. The heating part 320 covers the through hole 220, and a sealing ring 500 arranged around the through hole 220 is clamped between the heating part 320 and the bottom wall of the outer pot 200, and the mounting part 310 surrounds the outside of the heating part 320. Such a design allows the heating part 320 to directly contact the water in the outer pot 200, thereby improving the thermal efficiency of the electric stew pot, and the setting of the sealing ring 500 can increase the sealing of the through hole 220 of the outer pot, thereby avoiding local water leakage in the electric stew pot.

[0049] In order to enhance the connection reliability between the heating device 300 and the outer pot 200, there are multiple thermal insulation members 400, and the multiple thermal insulation members 400 are surrounded by the outside of the sealing ring 500, and the mounting portion 310 is correspondingly provided with multiple connecting holes 311, and the first fastener passes through the connecting hole 311 and is locked on the thermal insulation rod 410. Such a design can not only prevent the thermal insulation member 400 from interfering with the sealing ring 500, but also increase the connection reliability between the heating device 300 and the bottom wall of the outer pot.

[0050] It is understandable that in other embodiments of the present invention, the limiting ribs can also be independently processed and formed, and later fixed to the outer pot bottom wall by screws or bonding, so that a fixing groove is formed between the limiting ribs and the outer pot bottom wall.

[0051] It can be understood that in other embodiments of the present invention, the first groove wall is arranged in a ring shape and is integrally formed with the bottom wall of the outer pot, the first groove wall forms a groove opening open downward, the insulation head is inserted into the area surrounded by the first groove wall through the groove, and then the second groove wall is fixedly connected to the first groove wall by screws to limit the insulation head at the lower position, and the second groove wall is provided with a through hole for the insulation rod to pass through.

[0052] It can be understood that in other embodiments of the present invention, the first fastener may also be a clamping member, which passes through the mounting portion and is clamped and fixed to the thermal insulation member.

[0053] Embodiment 2

[0054] like Figure 6 As shown, compared with the first embodiment, the difference of this embodiment is that: the edge of the mounting portion 310 in this embodiment is provided with a notch 312, the heat insulating member 400 also includes a heat insulating sleeve 430, the heat insulating sleeve 430 is integrally formed at the end of the heat insulating rod 410 away from the heat insulating head 420, the heat insulating sleeve 430 is arranged to pass through the notch 312, and the end of the heat insulating sleeve 430 protrudes from the surface of the mounting portion 310, and the outer peripheral side of the heat insulating sleeve 430 is provided with two heat insulating sheets 440 arranged along the axial direction of the heat insulating sleeve 430, the projection of the heat insulating sheet 440 on the mounting portion 310 is larger than the notch 312 to prevent the heat insulating sheet 440 from passing through the notch 312, and the portion of the mounting portion 310 around the notch 312 is clamped between the two heat insulating sheets 440, so that the mounting portion 310 is initially vertically limited by the two heat insulating sheets 440, so as to facilitate the subsequent first fastener (screw) to pass through the heat insulating sleeve 430 and be connected and fixed to the heat insulating sleeve 430. With such a design, the mounting portion 310 and the first fastener can be separated by the heat insulation sleeve 430 to avoid contact between the mounting portion 310 and the first fastener, thereby reducing heat transfer from the mounting portion 310 to the first fastener, thereby reducing heat transfer to the heat insulation component 400, and further reducing the temperature rise of the bottom wall of the outer pot.

[0055] Preferably, the heat insulating sheet 440 includes a sheet body 441 and a plurality of reinforcing ribs 442 disposed on the sheet body 441 and extending toward another heat insulating sheet 440. A heat dissipation gap is formed between two adjacent reinforcing ribs 442 on the same sheet body 411, and the portion of the mounting portion 310 surrounding the notch 312 is clamped between the reinforcing ribs 442 of the two heat insulating sheets 440. With such a design, the contact area between the heat insulating sheet 440 and the mounting portion 310 can be reduced to reduce heat transfer, and at the same time, the heat of the mounting portion 310 and the heat insulating sheet 440 can also be dissipated into the air through the heat dissipation gap to further reduce the temperature rise of the heat insulating member 400.

[0056] It can be understood that in other embodiments of the present invention, the heat insulation sheet only includes a sheet body, and the portion of the mounting portion surrounding the notch is clamped between two sheet bodies.

[0057] It should be noted that, on the basis of Example 1, that is, in the scheme where the thermal insulation head 420 is laterally inserted into the fixing groove 210 through the notch 2110, the orientation of the notch 2110 matching the same thermal insulation component 400 is the same as the orientation of the opening of the notch 312. With such a design, in the process of inserting the thermal insulation head 420 of the thermal insulation component 400 into the fixing groove 210, the thermal insulation sleeve 430 can also be inserted into the notch 312, thereby reducing the difficulty of assembling the thermal insulation component 400 and the heating device 300.

[0058] Embodiment 3

[0059] Compared with the first and second embodiments, the difference of this embodiment is that the heat insulating member 400 is fixed to the bottom wall of the outer pot by the second fastener, and the second fastener is separated from the first fastener. Such a design can not only realize that the heat insulating member 400 is fixed to the bottom wall of the outer pot by the second fastener, but also can be separated from the first fastener by the second fastener, so as to prevent the heat of the first fastener from being transferred to the second fastener, thereby preventing the second fastener from transferring the heat of the first fastener to the bottom wall of the outer pot.

[0060] Specifically, the heat insulating member includes a heat insulating rod and a heat insulating head protruding from the outer peripheral side of one end of the heat insulating rod, a connecting column protruding from the outer side of the bottom wall of the outer pot, and the heat insulating head is fixed to the connecting column by a second fastener. The second fastener in this embodiment is a screw, which passes through the heat insulating head and is locked and fixed to the connecting column. The heat insulating rod abuts against the mounting portion and is connected to the first fastener or is connected to the first fastener through the heat insulating sleeve in the second embodiment. Such a design can not only increase the contact area between the heat insulating member and the bottom wall of the outer pot by setting the heat insulating head, thereby improving the support reliability of the heating device, but also facilitate the second fastener to fix the heat insulating member to the bottom wall of the outer pot, thereby reducing the difficulty of installing the second fastener, and at the same time prevent the first fastener from contacting the second fastener.

[0061] It can be understood that in other embodiments of the present invention, the second fastener may also be a clamping member, which passes through the thermal insulation head and is clamped and fixed to the connecting column.

[0062] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
