Description

Technical Field

[0001] This utility model relates to the field of pots, and in particular to a thin and lightweight pot that is resistant to deformation due to cold and heat. Background Technology

[0002] Pots are commonly used tools for cooking food, and are typically made of aluminum, cast iron, or stainless steel.

[0003] Chinese patent application No. 201510907577.5 discloses a dual-purpose flat-bottomed pan, including a pan body composed of a side wall and a bottom. The bottom is flat, the side wall is elliptical, and the bottom and side wall of the pan body form a rounded corner.

[0004] As people become more health-conscious and aware of the harmful effects of aluminum on the human body, they usually avoid aluminum pots and choose cookware made of cast iron or stainless steel instead. However, cast iron or stainless steel pots are generally heavy, making them difficult for people with less strength to handle. Therefore, to reduce the weight of the pot, the bottom and sides are usually made thinner. Although this reduces the weight of the pot, it makes it more prone to deformation when subjected to sudden temperature changes. Utility Model Content

[0005] This invention addresses the drawback of existing technologies that make the bottom and side walls of pots thinner to reduce weight, but this makes the pots more susceptible to deformation under sudden temperature changes. It provides a lightweight and thin pot that reduces the weight of the pot while maintaining its excellent resistance to temperature deformation.

[0006] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method: A thin and light pot that is resistant to cold and heat deformation includes a pot body, a weight-reducing groove is recessed at the bottom of the pot body, a baffle plate is provided at the bottom of the pot body to open or block the weight-reducing groove, and a heat-conducting and deformation-resistant structure is provided between the weight-reducing groove and the baffle plate to conduct heat from the bottom of the pot body to the baffle plate and reduce the deformation of the bottom of the pot body.

[0007] By adopting the above solution, the lightweight pot significantly reduces its weight by incorporating weight-reducing grooves. Since the bottom of the pot directly contacts the flame during cooking and experiences the highest temperature, as well as the greatest temperature difference when food is added, the bottom is most prone to deformation due to sudden temperature changes. By incorporating a baffle and a heat-conducting, deformation-resistant structure, the food contacts the baffle instead of directly contacting the bottom of the pot, significantly reducing deformation caused by sudden temperature changes. Furthermore, the heat-conducting, deformation-resistant structure transfers heat from the bottom of the pot to the baffle, preventing excessive heat on the baffle compared to direct contact with the flame, thus reducing the probability of deformation and burning of the food. The heat-conducting, deformation-resistant structure also provides support, further reducing deformation.

[0008] As a preferred embodiment, the thermally conductive and deformation-resistant structure includes a mounting column concentrically fixed inside the weight-reducing groove and a support strip arranged radially along the mounting column and abutting the mounting column and the inner ring wall of the weight-reducing groove at both ends, respectively. The upper and lower sides of the support strip abut against the bottom of the weight-reducing groove and the baffle plate, respectively.

[0009] With the above scheme, the two ends of the support bar abut against the mounting column and the inner ring wall of the weight reduction groove, respectively, so that the support bar can reduce the deformation of the bottom of the pot body along the radial direction of the mounting column; the upper and lower sides of the support bar abut against the bottom of the weight reduction groove and the baffle plate, respectively, so that the support bar can reduce the deformation of the bottom of the pot body along the axial direction of the mounting column.

[0010] Preferably, the support bars are arranged at axial intervals around the mounting column.

[0011] Preferably, the support bar is detachably disposed between the mounting column and the pot body, and the mounting column is provided with a slot for the end of the support bar away from the inner ring wall of the weight reduction groove to be inserted or pulled out along the axial direction of the mounting column.

[0012] Using the above scheme, fewer support bars result in a lighter overall pot body but lower resistance to deformation; conversely, more support bars result in a heavier overall pot body but better resistance to deformation. Based on different requirements for deformation resistance and lightweighting, an appropriate number of support bars are assembled into the weight-reducing groove. After the support bar is placed radially along the mounting post, its end closest to the mounting post is positioned above the slot. An external force is applied to drive it axially towards the bottom of the weight-reducing groove, with the end of the support bar near the mounting post inserted into the slot and the other end abutting against the inner ring wall of the weight-reducing groove. The end of the support bar inserted into the slot abuts against the inner wall of the slot. For disassembly, simply pull the support bar away from the bottom of the weight-reducing groove.

[0013] Preferably, a limiting structure is provided between the baffle and the pot body, which can lock together to prevent them from separating or releasing as they rotate relative to each other.

[0014] Using the above solution, before cooking, the baffle is rotated to the limiting structure to engage the baffle and the pot body, preventing them from separating. At the same time, the upper and lower sides of the support strip abut against the bottom of the weight-reducing groove and the baffle, respectively, so that the support strip can reduce the deformation of the bottom of the pot body along the axial direction of the mounting column. After cooking, the baffle is rotated to the limiting structure to release the limiting, and the baffle can be removed for easy cleaning and adjustment of the number of support strips in the weight-reducing groove.

[0015] Preferably, the limiting structure includes a locking block protruding from the bottom of the baffle plate and an arc-shaped protrusion protruding from the inner ring wall of the weight reduction groove, which allows the horizontal section of the locking block to press against its lower end face.

[0016] Using the above method, when the baffle is placed into the weight-reducing groove, the locking block and the arc-shaped protrusion are misaligned. The locking block is inserted into the weight-reducing groove along with the baffle. After rotating a certain angle, the arc-shaped protrusion engages with the horizontal section of the locking block and the baffle, thus achieving the engagement between the baffle and the weight-reducing groove. Conversely, when the baffle is rotated until the locking block disengages from the arc-shaped protrusion, the engagement is released, and the baffle can be easily removed.

[0017] Preferably, the side wall of the pot body is hollow to form a weight-reducing cavity, and a heat-conducting support block is fixedly installed inside the weight-reducing cavity, with its two ends respectively connected to the inner wall of the weight-reducing cavity near and away from the flame, so as to conduct heat and reduce the deformation of the side wall of the pot body.

[0018] The above solution involves setting a weight-reducing cavity inside the side wall of the pot to further reduce the weight of the pot. At the same time, a heat-conducting support block is set inside the weight-reducing cavity to conduct heat and reduce the deformation of the side wall of the pot.

[0019] This utility model, by adopting the above technical solutions, has significant technical effects: the weight-reducing groove and weight-reducing cavity are set to greatly reduce the weight of the pot; by setting a baffle plate and support strip, the food is made to contact the baffle plate instead of directly contacting the bottom of the pot, which greatly reduces the deformation of the bottom of the pot caused by sudden temperature changes; and because the support strip conducts the temperature of the bottom of the pot to the baffle plate, compared with direct contact with the flame, it can also prevent the temperature of the baffle plate from becoming too high, reducing the probability of deformation and the probability of food burning. The support strip can also play a supporting role to further reduce deformation. At the same time, a heat-conducting support block is set in the weight-reducing cavity to conduct heat and reduce the deformation of the side wall of the pot. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0023] Example A thin, lightweight pot resistant to deformation from cold and heat, as shown in the reference. Figures 1 to 4 The container includes a pot body 1 and a handle mounted on the pot body 1. The handle and the connection method between the handle and the pot body 1 are existing technologies and are not shown in the figure, so they will not be described in detail here.

[0024] The side wall of the pot body 1 is hollow to form a weight reduction cavity 9. A heat-conducting support block 10 is fixedly installed inside the weight reduction cavity 9, with its two ends fixedly connected to the inner wall of the weight reduction cavity 9 close to and away from the flame, respectively. The heat-conducting support block 10 realizes heat conduction and reduces the deformation of the circumferential wall of the pot body 1.

[0025] The bottom of the pot body 1 is recessed with a weight-reducing groove 2. In this embodiment, the weight-reducing groove 2 is a circle concentric with the pot body 1. A mounting post 4 is concentrically fixed in the weight-reducing groove 2. A slot 6 is provided on the mounting post 4. It also includes a support bar 5. After the support bar 5 is placed radially along the mounting post 4, its end near the mounting post 4 is located above the slot 6. An external force is applied to drive the support bar 5 to move axially along the mounting post 4 towards the bottom of the weight-reducing groove 2. The end of the support bar 5 near the mounting post 4 is inserted into the slot 6 and the other end abuts against the inner ring wall of the weight-reducing groove 2. The end of the support bar 5 inserted into the slot 6 abuts against the inner wall of the slot 6. This achieves that both ends of the support bar 5 abut against the mounting post 4 and the inner ring wall of the weight-reducing groove 2, respectively, so that the support bar 5 can reduce the deformation of the bottom of the pot body 1 radially along the mounting post 4. Several sets of slots 6 and support bars 5 are arranged axially around the mounting post 4. In this embodiment, six sets are provided.

[0026] The weight-reducing groove 2 is fitted with a baffle plate 3, which can open or close the weight-reducing groove 2. When the baffle plate 3 is removed, an appropriate number of support bars 5 are assembled into the weight-reducing groove 2 according to different deformation resistance and weight reduction requirements. The baffle plate 3 is then placed on top to block the weight-reducing groove 2, and a limiting structure is provided between the baffle plate 3 and the weight-reducing groove 2 to prevent them from separating. When the baffle plate 3 blocks and limits the weight-reducing groove 2, the upper and lower sides of the support bars 5 abut against the bottom of the weight-reducing groove 2 and the baffle plate 3 respectively, thereby reducing the deformation of the bottom of the pot body 1 along the axial direction of the mounting column 4. The food comes into contact with the baffle plate 3 instead of directly contacting the bottom of the pot body 1, which greatly reduces the deformation of the bottom of the pot body 1 caused by sudden temperature changes. Furthermore, since the support bars 5 conduct the temperature of the bottom of the pot body 1 to the baffle plate 3, compared to direct contact with the flame, it can also prevent the temperature on the baffle plate 3 from becoming too high, reducing the probability of deformation and also reducing the probability of food burning.

[0027] The limiting structure includes a locking block 7 protruding from the bottom of the baffle plate 3, with the bottom of the baffle plate 3 being the side closest to the bottom of the weight-reducing groove 2. The locking block 7 includes a vertically protruding section 702 from the bottom of the baffle plate 3 and a horizontal section 701 fixedly disposed at the end of the vertical section 702 away from the baffle plate 3, parallel to the bottom of the baffle plate 3, forming a clamping gap 11 between the horizontal section 701 and the bottom of the baffle plate 3. An arc-shaped protruding ridge 8 is protruding from the inner ring wall of the weight-reducing groove 2, and the arc-shaped protruding ridge 8 is concentrically arranged with the weight-reducing groove 2.

[0028] When the baffle plate 3 is placed into the weight-reducing groove 2, the locking block 7 and the arc-shaped protrusion 8 are misaligned. The locking block 7 is inserted into the weight-reducing groove 2 along with the baffle plate 3. The upper end face of the arc-shaped protrusion 8 fits against the baffle plate 3, restricting the baffle plate 3 from further insertion into the weight-reducing groove 2. After the locking block 7 rotates a certain angle with the baffle plate 3, the arc-shaped protrusion 8 slides into the clamping gap 11. The lower end face of the arc-shaped protrusion 8 abuts against the upper end face of the horizontal section 701, realizing the locking between the baffle plate 3 and the weight-reducing groove 2. The lower end face of the arc-shaped protrusion 8 is the side closest to the bottom of the weight-reducing groove 2, and the upper end face of the arc-shaped protrusion 8 is the side away from the bottom of the weight-reducing groove 2. The upper end face of the horizontal section 701 is the side away from the bottom of the weight-reducing groove 2. In this embodiment, two sets of locking blocks 7 and arc-shaped protrusions 8 are arranged axially around the weight-reducing groove 2. When it is necessary to remove the cover plate 3, rotate the cover plate 3 to make the arc-shaped protrusion 8 disengage from the clamping gap 11 and separate from the card block 7 to complete the unlocking.
