Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a rice cooker body and a microwave rice cooker. Background Technology

[0002] For microwave heating appliances, when the lid is closed, it is necessary to ensure that the metal cavity and the metal door are in close contact, and there are certain requirements for the contact distance (based on the requirement that the microwave leakage is acceptable).

[0003] In existing cooking appliances, such as rice cookers, the outer pot of the cooking vessel is the cavity, which is rotatably mounted under the outer casing. In this method, the cavity's flange is not an external surface and is hidden beneath the casing. While this prevents the cavity from detaching from the front of the casing, it doesn't achieve a snug fit between the cavity and the door to shield against microwaves. Another method is the microwave oven cavity, which is a square cavity formed by splicing multiple steel plates. It's not a single, stretched piece, and requires an additional welded metal panel on its surface. Each side of this square cavity is formed by welding multiple sheet metal pieces, resulting in right angles. However, in the case of microwave rice cookers, which open from the top, rice water or other liquids can spill into the cavity. In such cases, right angles in the cavity would make cleaning difficult. Therefore, microwave rice cookers require smooth, seamless surfaces and corners, with large rounded corners for easy cleaning. For areas visible or requiring cleaning, the cavity (metal sheet metal) must be a single, stretched piece.

[0004] In related technologies, the integral stretched cavity of a microwave rice cooker needs to be fixed together with the outer shell (injection molded part). Because it is necessary to ensure that a certain width of flat surface around the cavity is exposed on the front of the outer shell and in contact with and fits the door (for the cavity and the top cover door to form a closed space to shield microwaves), and because the injection molded part and the metal cavity cannot be connected by welding, it is difficult to reliably fasten the outer shell and the metal cavity together. If it cannot be ensured that the outer shell and the cavity are reliably fastened together, the entire cavity assembly will detach from the front of the outer shell. Utility Model Content

[0010] In one embodiment, the connecting segment is bent relative to the main body segment and located on the side of the main body segment close to the bottom wall of the microwave shielding cavity. The extension segment extends outward relative to the connecting segment, and the hook segment extends relative to the extension segment away from the bottom wall of the microwave shielding cavity. The main body segment, the connecting segment, and the outer wall of the microwave shielding cavity enclose a first abutting space. The connecting segment, the extension segment, and the hook segment enclose a second abutting space. The second abutting space is located above the extension segment. The support frame and the outer shell are respectively disposed in the first abutting space and the second abutting space.

[0011] In one embodiment, the support frame has a first stepped surface, a second stepped surface, and an inclined surface. The inclined surface is located between the first stepped surface and the second stepped surface and connects the first stepped surface and the second stepped surface. The first stepped surface abuts against the main body section, the inclined surface abuts against the connecting section, and the second stepped surface abuts against the extension section.

[0014] In one embodiment, the outer casing has open ends and a cavity is formed inside the outer casing. The inner circumferential surface of the outer casing has a protruding abutment portion.

And / or, the outer circumference of the support frame has a plurality of first connecting portions and the outer circumference of the outer casing has a plurality of second connecting portions.

The bottom of the microwave shielding cavity is connected to the shielding cover. The magnetron and the mounting bracket are both disposed inside the shielding cover. The mounting bracket has a protruding limiting portion, forming a placement space within the limiting portion. The snap-action temperature controller is placed in the placement space. The mounting bracket is connected to the shielding cover and partially contacts and fits against the magnetron to seal the placement space, thereby allowing the snap-action temperature controller to contact the magnetron.

The flange is positioned between the outer shell and the support frame, and the outer shell and support frame clamp the flange to fix the microwave shielding cavity. At the same time, the surface of the flange forms an external surface for contact and contact with the cover, forming a closed space to shield microwaves.

[0029] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0032] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0033] Microwave-heated appliances, when closed, must ensure that the metal cavity and metal door are in close contact, and the contact distance must meet certain requirements (based on acceptable microwave leakage). In related technologies, the integral stretched cavity of a microwave rice cooker needs to be fixed together with the outer shell (injection molded part). This is because a certain width of flat surface around the cavity needs to be exposed on the front of the outer shell and in close contact with the door (to form a closed space between the cavity and the top cover to shield microwaves). Furthermore, since the injection molded part and the metal cavity cannot be connected by welding, it is difficult to reliably fasten the outer shell and the metal cavity together. If the outer shell and the cavity cannot be reliably fastened together, the entire cavity assembly may detach from the front of the outer shell.

[0034] In view of this, and in response to the problem that the outer shell and the metal cavity are difficult to secure reliably together, this utility model proposes a cooker body 10 and a microwave rice cooker 100, which aims to achieve reliable fixation between the integral stretch cavity and the injection-molded outer shell.

[0035] The specific structure of the rice cooker body 10 and the microwave rice cooker 100 of this utility model will be described below:

[0036] Please refer to Figures 1 to 7 This utility model proposes a cooker body 10, which is applied to a microwave rice cooker 100. The cooker body 10 includes: a main body (not shown in the figure), a microwave shielding cavity 11 provided inside the main body, the microwave shielding cavity 11 having an opening 111, a flange 112 provided at the opening 111, the flange 112 being arranged around the opening 111; a support frame 12, the support frame 12 being sleeved on the outside of the microwave shielding cavity 11; and an outer shell cover 13, the outer shell cover 13 being sleeved on the outside of the support frame 12, the outer shell cover 13 and the support frame 12 being sandwiched between the flange 112.

[0037] Specifically, the main body of the pot includes a microwave shielding cavity 11 with an opening 111. The microwave shielding cavity 11 is used to fit against the lid 20 to form a closed chamber to shield microwaves. The main body of the pot also includes an inner pot for holding food, which is placed inside the microwave shielding cavity 11 through the opening 111. A support frame 12 and an outer shell 13 are sequentially fitted around the microwave shielding cavity 11. The outer shell 13 is used to protect the internal components. A flange 112 is provided on the outside of the microwave shielding cavity 11, which surrounds the opening 111. The support frame 12 and the outer shell 13 are clamped on the flange 112. The outer shell 13 and the support frame 12 respectively exert forces on the microwave shielding cavity 11 in two opposite directions, so as to reliably fix the microwave shielding cavity 11 and the outer shell 13.

[0038] The microwave shielding cavity 11 is placed between the outer shell 13 and the support frame 12. The microwave shielding cavity 11 is clamped by the fastening of the outer shell 13 and the support frame 12. The clamping method of the outer shell 13 and the support frame 12 can ensure that the outer shell 13 and the microwave shielding cavity 11 are reliably fastened together, ensuring that the entire microwave shielding cavity 11 assembly will not come out from the front of the outer shell 13, and is easy to assemble and disassemble. The clamping method can ensure that the microwave shielding cavity 11 will not move or loosen due to external force during operation.

[0039] Meanwhile, the surface of the flange 112 forms the outer surface, and the flange 112 design provides a good sealing effect. The flange 112 is used to fit with the cover 20 to form a closed space, thereby effectively shielding microwaves. This fixing method not only solves the problem of reliable fixing of the integral stretch cavity and the injection-molded outer shell, but also avoids deformation of the microwave shielding cavity 11, maintains the fit between the microwave shielding cavity 11 and the cover 20, thereby effectively shielding microwaves and improving the reliability of microwave shielding.

[0040] The specific clamping method can be set according to the structure of the flange 112 and actual needs. In one embodiment, the flange 112 extends toward the side away from the opening 111, and the outer shell 13 and the support frame 12 are clamped on the two walls of the flange 112; in another embodiment, the flange 112 extends toward the side away from the opening 111 and is bent, and the outer shell 13 and the support frame 12 are clamped on both sides of the flange 112.

[0041] The shape of the flange 112 can be set according to actual needs. It can be set to extend in one direction or be set to bend multiple times, so as to better cooperate with the support frame 12 and the outer shell 13. The outer shell 13 and the support frame 12 can be fixed to the main body of the pot, or the outer shell 13 and the support frame 12 can be fixed to each other to better fix the microwave shielding cavity 11.

[0042] This utility model's technical solution involves setting a flange 112 on a microwave shielding cavity 11, with a support frame 12 and an outer shell 13 clamping the flange 112. The flange 112 is positioned between the outer shell 13 and the support frame 12, and the outer shell 13 and the support frame 12 clamp the flange 112 to fix the microwave shielding cavity 11. At the same time, the surface of the flange 112 forms an outer surface for contacting and fitting with the cover 20, forming a closed space to shield microwaves. This achieves reliable fixation of the integral stretch cavity and the injection-molded outer shell, while maintaining the fit between the microwave shielding cavity 11 and the cover 20 to form a closed space, thereby effectively shielding microwaves. Assembly is simple and convenient.

[0043] In an embodiment of this utility model, the flange 112 includes a main body segment 1121 and a connecting segment 1122. The main body segment 1121 is connected to the microwave shielding cavity 11, and the connecting segment 1122 is bent and connected to the side of the main body segment 1121 away from the microwave shielding cavity 11. The support frame 12 and the outer shell 13 are sandwiched between the main body segment 1121 and / or the connecting segment 1122.

[0044] In detail, the flange 112 is configured as two segments. The main body segment 1121 extends from the microwave shielding cavity 11 in a direction away from the microwave shielding cavity 11, while the connecting segment 1122 extends from the main body segment 1121 by bending. This design allows for clamping from different directions, and the most suitable clamping method can be selected according to actual needs. The combination of the parallel segment and the bent segment provides a variety of clamping options, and the clamping strategy can be flexibly adjusted according to the specific application scenario to achieve the best fixing effect.

[0045] In one embodiment, the support frame 12 and the outer casing 13 are clamped on the main body section 1121, so that the clamping force is evenly distributed on the surface of the microwave shielding cavity 11, avoiding deformation or damage caused by excessive local stress. The parallel surface provides a larger contact area, which helps to improve the stability of the microwave shielding cavity 11 in the working state. The bent section can serve as a reference point to help align and parallelize more quickly during installation, simplifying the assembly process.

[0046] In another embodiment, the support frame 12 and the outer shell 13 are clamped between the main body section 1121 and the connecting section 1122. By simultaneously clamping the parallel section and the bent section, a more stable fixing effect can be achieved, reducing the movement of the microwave shielding cavity 11 during use.

[0047] In an embodiment of this utility model, the flange 112 further includes an extension section 1123, which is bent and connected to the connecting section 1122. The support frame 12 and the outer shell 13 are sandwiched between at least one of the main body section 1121, the connecting section 1122 and the extension section 1123.

[0048] Specifically, an extension section 1123 is also provided. The extension section 1123 is a further bend and extension based on the connecting section 1122. Therefore, the extension section 1123 can be designed to be parallel to the main section 1121 or at an angle to the main section 1121. This method allows clamping from the top and bottom, left and right, or diagonal directions, increasing the diversity of clamping methods and allowing the selection of the most suitable fixing direction according to different application scenarios. At the same time, three different fixing points can provide better support and stability, better distribute stress, and avoid deformation or damage caused by excessive pressure on a single area.

[0049] Given the limited space within the cooker body 10, this design allows for clamping from multiple angles, thus enabling better fixation of the microwave shielding cavity 11 within a confined space.

[0050] In an embodiment of this utility model, the flange 112 further includes a hook section 1124, which is bent and connected to the extension section 1123, and the hook section 1124 is fastened to the outer shell cover 13.

[0051] Specifically, the hook segment 1124 can abut against the outer casing 13, or it can limit the outer casing 13. For example... Figure 6 By setting the hook section 1124, the hook section 1124 limits the outer shell 13, which can play a certain role in preventing loosening, preventing the outer shell 13 from loosening during use, and can also serve as an auxiliary positioning device to ensure that the installation of the outer shell 13 can reach the preset position, ensuring the stability of the microwave shielding cavity 11 during long-term operation, avoiding the microwave shielding cavity 11 from falling off or shifting due to loose clamping, and enhancing the stability of the connection.

[0052] In an embodiment of this utility model, the connecting segment 1122, after being bent relative to the main body segment 1121, is located on the side of the main body segment 1121 near the bottom wall of the microwave shielding cavity 11. The extension segment 1123 extends outward relative to the connecting segment 1122, and the hook segment 1124 extends relative to the extension segment 1123 away from the bottom wall of the microwave shielding cavity 11. The main body segment 1121, the connecting segment 1122, and the outer wall of the microwave shielding cavity 11 enclose a first abutting space 1125, which is located below the main body segment 1121, meaning below the microwave rice cooker 100 in its operating state. The connecting segment 1122, the extension segment 1123, and the hook segment 1124 enclose a second abutting space 1126, which is located above the extension segment 1123, meaning above the microwave rice cooker 100 in its operating state. The support frame 12 and the outer shell 13 are respectively disposed in the first abutment space 1125 and the second abutment space 1126.

[0053] It is worth noting that, such as Figure 6 Two abutment spaces are formed on the flange 112. The support frame 12 extends into the first abutment space 1125, and the outer shell 13 extends into the second abutment space 1126 to clamp the flange 112. The specific shapes of the first abutment space 1125 and the second abutment space 1126 can be set according to actual needs. They can be set as rectangles, cones, arcs, etc.

[0054] By forming two abutment spaces, the microwave shielding cavity 11 can be clamped in different areas, providing a more uniform clamping force distribution, improving the overall installation stability of the microwave shielding cavity 11, and enhancing its torsional resistance.

[0055] Setting up the first supporting space 1125 and the second supporting space 1126 can achieve multi-point fixation, making the microwave shielding cavity 11 less prone to displacement, reducing the offset or vibration that may be caused by single-point fixation, and improving the overall structural stability.

[0056] Furthermore, in one embodiment, such as Figure 6 The main body section 1121 and the extension section 1123 are arranged horizontally, while the connecting section 1122 and the hook section 1124 extend vertically. Thus, the first abutment space 1125 and the second abutment space 1126 are arranged in a rectangle, which can provide multi-directional support and make the whole structure more stable. This arrangement can provide a clear reference surface, which helps to achieve high-precision positioning and alignment during assembly, and facilitates adjustment and fine-tuning, ensuring that the microwave shielding cavity 11 is fixed in an accurate position.

[0057] In an embodiment of this utility model, the support frame 12 is provided with a first stepped surface 121, a second stepped surface 122 and an inclined surface 123. The inclined surface 123 is disposed between the first stepped surface 121 and the second stepped surface 122 and connects the first stepped surface 121 and the second stepped surface 122. The first stepped surface 121 abuts against the main body section 1121, the inclined surface 123 abuts against the connecting section 1122, and the second stepped surface 122 abuts against the extension section 1123.

[0058] In detail, such as Figure 6 The support frame 12 cooperates with the flange 112 through the first step surface 121, the second step surface 122 and the inclined surface 123. The first step surface 121 and the second step surface 122 can cooperate with the outer shell cover 13 to clamp the flange 112. The inclined surface 123 abuts against the connecting section 1122 and can perform a limiting cooperation to improve the positioning accuracy.

[0059] The design of the first step surface 121 and the second step surface 122 can provide additional support points, making the clamping more stable. By increasing the step surface, stress can be distributed to a larger contact surface. At the same time, the design of the two step surfaces can be achieved without increasing the volume of the support frame 12, which can provide better fixation and optimize space utilization.

[0060] In an embodiment of this utility model, the support frame 12 includes a frame body 124, with open ends at opposite ends of the frame body 124 and a cavity formed inside the frame body 124. The frame body 124 is fitted onto the outside of the microwave shielding cavity 11, and the end of the frame body 124 is used to abut against the flange 112.

[0061] It is worth noting that the frame body 124 is fitted onto the outside of the microwave shielding cavity 11 through the opening 111. The end of the frame body 124 has a supporting end 1241 that mates with the flange 112 of the microwave shielding cavity 11. The supporting end 1241 of the frame body 124 can directly abut against the flange 112, making the connection between the frame body 124 and the microwave shielding cavity 11 tighter and effectively increasing the stability of the overall structure. When the frame body 124 directly abuts against the flange 112, it reduces shaking or displacement caused by external forces. This design makes the assembly process simpler and faster; it only requires fitting the frame body 124 onto the outside of the microwave shielding cavity 11, ensuring that its end abuts against the flange 112.

[0062] In an embodiment of this utility model, the side wall of the frame body 124 is provided with one of a buckle 1242 and a slot 113, and the microwave shielding cavity 11 is provided with the other of a buckle 1242 and a slot 113, wherein the buckle 1242 is connected to the slot 113 in a cooperative manner; and / or, the side wall of the frame body 124 is provided with a first buckle 1243, and the microwave shielding cavity 11 is provided with a second buckle 114, wherein the first buckle 1243 is connected to the second buckle 114 in a cooperative manner.

[0063] Specifically, in one embodiment, a buckle 1242 is provided on the side wall of the frame body 124, and a matching slot 113 is provided on the microwave shielding cavity 11. The frame body 124 is connected to the microwave shielding cavity 11 through the buckle 1242 and the slot 113. In another embodiment, a slot 113 is provided on the side wall of the frame, and a matching buckle 1242 is provided on the microwave shielding cavity 11.

[0064] Furthermore, a first snap fastener 1243 and a second snap fastener 114 can be provided between the frame body 124 and the microwave shielding cavity 11 for a more stable connection.

[0065] The engagement between the buckle 1242 and the slot 113 or the first snap buckle 1243 and the second snap buckle 114 can serve as a pre-positioning method to ensure that the expected position is achieved each time the installation is completed, making installation convenient and the connection stable.

[0066] In an embodiment of this utility model, the outer casing 13 has openings at both ends and a cavity is formed inside the outer casing 13. The inner circumferential surface of the outer casing 13 is provided with a supporting portion 131. The supporting portion 131 is bent and extended from the end face of the outer casing 13 toward the cavity of the outer casing 13. The supporting portion 131 is used to abut against the flange 112. And / or, the outer circumference of the support frame 12 is provided with a plurality of first connecting portions 125, and the outer circumference of the outer casing 13 is provided with a plurality of second connecting portions 132. The first connecting portions 125 and the second connecting portions 132 are connected and fixed one by one by screws.

[0067] In detail, such as Figure 4 and Figure 6 The outer casing 13 is designed with a ring of abutment 131, which is fitted with the flange 112 groove of the microwave shielding cavity 11 to press down and support the flange 112, making clamping more convenient and stable.

[0068] Furthermore, the support frame 12 is fitted onto the microwave shielding cavity 11, and then assembled together with the outer shell 13. At this time, the outer shell 13 and the support frame 12 clamp the flange 112 of the microwave shielding cavity 11. Specifically, multiple first connecting parts 125 and multiple second connecting parts 132 are respectively provided on the support frame 12 and the outer shell 13, and the two are connected and fixed by screws, providing a more reliable clamping force and preventing the clamping force from weakening or being lost during use. The outer shell 13 and the support frame 12, which are fixed together, can ensure that the microwave shielding cavity 11 will not be dislodged from its fixed position due to external forces during use, thus improving the stability of the connection.

[0069] like Figure 4 The first connecting part 125 is a combination of a connecting groove and a connecting plate, and the second connecting part 132 is a connecting post. The support frame 12 and the outer casing 13 are fastened by peripheral screws.

[0070] In an embodiment of this utility model, the cooker body 10 further includes a shielding cover 14, a magnetron 15, a snap-action temperature controller 16, and a mounting bracket 17. The bottom of the microwave shielding cavity 11 is connected to the shielding cover 14. The magnetron 15 and the mounting bracket 17 are both disposed inside the shielding cover 14. A limiting part 171 protrudes from the mounting bracket 17, forming a placement space (not shown in the figure). The snap-action temperature controller 16 is placed in the placement space. The mounting bracket 17 is connected to the shielding cover 14 and partially contacts and fits against the magnetron 15 to close the placement space, so that the snap-action temperature controller 16 contacts the magnetron 15.

[0071] It is worth noting that, such as Figure 7 As shown, the snap-on temperature controller 16 is used to detect the temperature of the magnetron 15 to prevent overload. The snap-on temperature controller 16 is first installed on the mounting bracket 17, and then the mounting bracket 17 presses the snap-on temperature controller 16 onto the magnetron 15 when it is installed on the waveguide box 18.

[0072] In addition, the cook body 10 also includes a waveguide box 18, a magnetron 15, a frequency converter, and various components enclosed in a shielding cover 14, located below the microwave shielding cavity 11. The shielding cover 14 contains a snap-on temperature controller 16 and a mounting bracket 17. The mounting bracket 17 has a limiting part 171 for fixing the snap-on temperature controller 16. When installing the mounting bracket 17, the snap-on temperature controller 16 is pressed down onto the magnetron 15. The magnetron 15 is fastened to the waveguide box 18 with screws, and the mounting bracket 17 is also fastened to the waveguide box 18 with screws. By fixing the snap-on temperature controller 16 to the mounting bracket 17, the snap-on temperature controller 16 and the magnetron 15 can be brought into contact and fit together. The snap-on temperature controller 16 and the magnetron 15 do not require separate screw fixing, reducing the number of components used.
