Modes for Carrying Out the Invention
[0019] We will further explain the specific implementation status of the present invention in combination with the drawings. It should be noted here that the explanations for these embodiments are used to help understand the present invention, but do not limit the present invention. Example 1
[0020] As shown in FIGS. 1-2, the microwave heating pot includes an outer shell 1, a pot body 2, and a pot lid 3 for combining the pot body 2. An exhaust port 4 is installed on the pot lid 3. The pot body 2 is made of metal, and a microwave absorption layer 5 is attached to the bottom surface of the pot body 2. The base adhesive 6 covers the microwave absorption layer 5 to fix the microwave absorption layer 5 to the bottom surface of the pot body 2. A fixing structure is provided inside the outer shell 1, and a gap is formed between the outer shell 1 and the pot body 2 by the fixing structure. The fixing structure fixes the pot body 2 inside the outer shell 1. When a gap is formed between the outer shell 1 and the outer wall of the pot body 2 by the fixing structure, during microwave heating, the microwave absorption layer absorbs microwave energy and converts it into thermal energy to heat the bottom of the pot body and cook the food in the pot. In addition, the heat generated in the microwave absorption layer 5 heats the air between the pot body and the outer shell through the base adhesive, increases the pressure, and arranges the fixing structure so that the high-pressure air generated in the microwave heating pot can be discharged along the gap between the outer wall of the pot body 2 and the inner wall of the outer shell 1.
[0021] Specifically, the fixing structure is a rib 7. The rib 7 abuts against the outer surface of the pot body 2. The rib 7 abuts against the pot body 2 with a clamping allowance to fix the pot body 2 inside the outer shell 1, so that the pot body 2 does not shake and scatter the food during heating. When it is necessary to clean the pot body 2, the pot body 2 can be taken out of the outer shell for convenient cleaning. In addition, since there is a rib 7 between the outer shell 1 and the pot body 2, the high-pressure air generated when the microwave heating pot overheats is discharged through the gap between the pot body 2 and the outer shell 1 from both sides of the rib 7, achieving safe pressure release of the microwave heating pot and ensuring the safety of the user during use.
[0022] In a more preferred embodiment, a silicon rubber sealing ring is provided on the pot body. Since there is a clamping allowance between the silicon rubber sealing ring and the rib 7, the pot body can be fixed within the outer shell. Due to the presence of the silicon rubber sealing ring, the outer shell will not cause large deformation when fitting the pot body, effectively protecting the service life of the outer shell and improving the user experience.
[0023] Furthermore, to facilitate the user's use, the pot lid 3 is made of metal. A handle 8 is provided on the upper part of the pot lid 3, and an insulating ring 9 that adheres closely to the pot body 2 is fitted on the edge of the pot lid 3, effectively preventing the phenomenon of catching fire and better keeping the food in the pot warm.
[0024] The outer shell 1 is made of a plastic material. When the pot body 2 is placed into the outer shell 1, the rib 7 is pressurized on the pot body 2, causing a slight deformation, so that the rib 7 can better clamp the pot body 2. After the pot body 2 is taken out of the outer shell 1, the deformation of the rib 7 ends and returns to its original state. Embodiment 2
[0025] As shown in Fig. 3-5, a protrusion 11 is provided on the inner wall of the outer shell 1, a handle 10 is provided on the outer shell 1, a clamping part is provided on the handle 10, and a fixing structure is formed by the protrusion 11 and the clamping part. The clamping part has an elastic member 14, a handle cover 12, and an actuating piece 13. The handle cover 12 is fixed on the handle 10, a first moving groove 124 is provided on the handle cover 12, the actuating piece 13 slides in the first moving groove 124, the tail end of the actuating piece 13 is connected to the elastic member 14, and the elastic member 14 pushes the actuating piece 13 into the inner cavity of the pot body 2 so that the end of the actuating piece 13 penetrates through the first hole 101 of the pot body 2. The elastic member 14 may be made of a deformable material such as a spring, silicon rubber, or flexible plastic. When the user slides the pressing part of the actuating piece 13 forward, the front section of the actuating piece 13 protrudes forward. At this time, the pot body 2 is fixed in the outer shell 1 by sandwiching the pot body 2 between the protrusion 11 and the actuating piece 13. When the user uses the microwave heating pot, the internal pressure of the pot body 2 is discharged from the gap between the protrusion 11 and the actuating piece 13 and the pot body 2 to ensure the safety of the user during use. When it is necessary to clean the pot body 2, the user slides the pressing part of the actuating piece 13 backward to contract the actuating piece 13 backward. At this time, when a large gap is opened between the outer shell 1 and the pot body 2, the user can easily take out the pot body 2 from the outer shell 1, facilitating the cleaning of the microwave heating pot.
[0026] As shown in Fig. 5, the handle cover 12 closes the first recess of the handle. Second sliding grooves 103 are symmetrically arranged on both side walls of the first recess. The actuating piece 13 has a guide plate 132, an end plate 131, and a pressing part 130. The guide plate 132 is fitted into the second sliding groove 103 and slides therein. The end of the end plate 131 is suitable for reciprocating movement in the first hole 101, and the pressing part 130 is located above the first moving groove 124. A third sliding groove 102 is installed in parallel on the second sliding groove 103. First retaining hooks 123 are installed on the left and right sides of the handle cover 12. The first retaining hooks 123 are fastened on the third sliding groove 102. A back plate 121 is installed at the rear of the handle cover 12, and an elastic member 14 is pressed against the back plate 121. As shown in Fig. 5, the elastic member 14 is a V-shaped member. The bifurcated ends 142 of the elastic member 14 are pressed against the back plate 121, and the tip 141 of the elastic member is pressed against the end plate 131. A positioning groove 104 is provided at the bottom of the first recess. The positioning groove 104 is a concave groove opened in the bottom wall. A second retaining hook 122 is installed on the handle cover 12. The positioning groove 104 functions to form a fastening connection with the second retaining hook 122. By fastening the first retaining hook 123 to the third sliding groove 102, the installation and fixation of the handle cover 12 are achieved.
[0027] When the connecting plate 134 connects the end plate 131 and the pressing part 130 and is located in the first moving groove 124, by pushing the pressing part 130, the end plate 131 is elastically pressed against the elastic part 14 backward, and the end of the end plate 131 shrinks into the first recess, so that the restraint on the pot body can be released.
[0028] The structures of the pot body, the pot lid, etc. are the same as those in Embodiment 1, and will not be described repeatedly here. Embodiment 3
[0029] As shown in FIGS. 6-7, a fastening portion 15 is provided on the inner wall of the outer shell 1. The fastening portion 15 has a first position limiting groove 17 and a second position limiting groove 18. A position limiting boss 19 is installed between the first position limiting groove 17 and the second position limiting groove 18, and a flange portion 16 is provided on the outer wall of the pot body 2. During use, when the user rotates the pot body 2, the flange portion 16 on the outer wall of the pot body 2 enters the first position limiting groove 17 and hits the position limiting boss 19. When the position limiting boss 19 contacts the flange portion 16, the user may cause a slight deformation of the position limiting boss 19 by applying a little force, and the flange portion 16 enters the second position limiting groove 18 through the position limiting boss 19, thereby restricting the flange portion 16 within the second position limiting groove 18, and ultimately fixing the pot body within the outer shell. Since the groove walls of the first position limiting groove 17 and the second position limiting groove 18 protrude from the inner wall of the outer shell, a gap is formed between the pot body 2 and the outer shell 1. Therefore, the gas generated when the microwave heating pot performs heating is discharged from this gap, improving the safety of the microwave heating pot. When it is necessary to clean the pot body of the microwave heating pot, by being able to rotate the pot body 2 in the reverse direction, it becomes possible to easily remove the pot body 2, making it convenient for the user to perform later cleaning.
