Description

Technical Field

[0001] This utility model relates to the field of cooking utensil technology, and in particular to a cooking utensil with an anti-scalding device. Background Technology

[0002] Traditional cooking appliances, such as electric ceramic stoves and electric baking pans, have exposed heating surfaces. Even after use and the heated kettle or other containers are removed, the heating surfaces remain very hot. Users cannot determine the temperature by looking at the surface alone. In addition, the control panel is close to the heating surface, making it easy to accidentally touch and cause burns.

[0003] To address this issue, patent number 202220262426.4 discloses a cooker and cooking appliance. By incorporating an alarm device, a lifting device, and a control device into the cooker, the control device raises the lifting device when cooking is finished. A first detection element monitors the detection area, and the alarm device promptly sounds an alarm when the user's hand is in the detection area. This prevents the user from being burned and improves the safety of using the cooking appliance.

[0004] However, the aforementioned cooking appliances involve electric lifting devices and detection components. When the electric lifting device or the detection component fails, it is impossible to detect the user's hand, which can easily lead to burns. In addition, the structure is complex and the production and maintenance costs are high.

[0005] Therefore, it is necessary to propose a new type of cooking appliance with an anti-scalding device to solve the above problems. This would address the issues of traditional cooking appliances, such as the inability to detect the user's hand when the electric lifting device or the detection component fails, the risk of burns, the complex structure, and the high production and maintenance costs. Summary of the Invention

[0006] This utility model provides a cooking appliance with an anti-scalding device, which solves the problems of traditional cooking appliances, such as the inability to determine the user's hand when the electric lifting device or the detection component fails, which can easily cause burns, and the complex structure and high production and maintenance costs.

[0007] The technical problem solved by this utility model is achieved by the following technical solution:

[0008] A cooking appliance with an anti-scalding device includes a base, a heating element fixed relative to the base, a power source electrically connected to the heating element, a guardrail, and an elastic element. The guardrail surrounds the heating element and has a support rod extending above the heating element. The two ends of the elastic element are fixed relative to the guardrail and the base, respectively. When the top of the support rod is pressed down by an external force, the guardrail descends; when the external force on the top of the support rod is removed, the guardrail rises above the heating element due to the elastic force of the elastic element.

[0009] Furthermore, it also includes a cover, with an opening above the base, the cover being connected to the opening, and a through-hole in the middle of the cover, forming a gap between the through-hole and the heating device to accommodate the guardrail.

[0010] Furthermore, it also includes a positioning spring and a ball bearing. The side wall of the cover is provided with a spring hole leading to the outer wall of the guardrail. One end of the positioning spring is fixed relative to the cover, and the other end extends into the spring hole and abuts against the ball bearing. The ball bearing also abuts against the outer wall of the guardrail.

[0011] Furthermore, it also includes a column, the bottom of which is located on the inner bottom surface of the base, and the top of which supports the heating device.

[0012] Furthermore, the elastic element is a tension spring, with one end fixed to the guardrail and the other end fixed to the bracket.

[0013] Furthermore, the elastic element is a spring, with one end of the elastic element abutting against the bottom of the outer side of the guardrail and the other end of the elastic element abutting against the bottom of the inner side of the base.

[0014] Furthermore, it also includes a switch that abuts against the guardrail. The switch is connected in series with the heating device and the power supply. When the guardrail descends, it pushes the switch to close, thereby connecting the heating device to the power supply. When the guardrail rises, it disengages from the switch, causing the switch to open and thus disconnecting the heating device from the power supply.

[0015] Furthermore, the heating device has a channel in the middle, the guardrail includes a base plate and a surrounding edge extending upward from around the base plate, and the support rod extends upward from the base plate and into the channel.

[0016] Furthermore, the switch is a micro switch, and the actuating end of the switch abuts against the base plate.

[0017] Furthermore, it also includes a crystal plate that covers the top of the heating device.

[0018] Furthermore, it also includes a water guide pipe, the crystal plate has a through hole that allows the support rod to pass through, the water guide pipe passes through the top and bottom of the heating device, the top of the water guide pipe communicates with the through hole, and the support rod passes through the water guide pipe.

[0019] Furthermore, it also includes a pressure ring, which is fixed to the heating device, and the middle part of the pressure ring is fixed to the top of the water pipe.

[0020] The beneficial effects of this utility model are:

[0021] This invention features a guardrail surrounding a heating element, with a support rod extending above the heating element. Two ends of an elastic element are fixed to the guardrail and a base, respectively. When the top of the support rod is pressed down by an external force, the guardrail descends; when the force is released, the guardrail rises above the heating element due to the elastic force. This simple mechanical structure effectively prevents users from accidentally touching the hot heating surface. The protective measures are durable and unlikely to fail, and the structure is simple, resulting in low production and maintenance costs. Attached Figure Description

Detailed Implementation

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0030] Example 1, see Figures 1 to 4A cooking appliance with an anti-scalding device includes a base 1, a heating element 2 fixed to the base 1, a power source electrically connected to the heating element 2, a guardrail 3, and an elastic element 4. The guardrail 3 surrounds the heating element 2 and has a support rod 5 extending above the heating element 2. The two ends of the elastic element 4 are fixed to the guardrail 3 and the base 1 respectively. When the top of the support rod 5 is pressed down by an external force, the guardrail 3 descends; when the external force on the top of the support rod 5 is removed, the guardrail 3 rises above the heating element 2 due to the elastic force of the elastic element 4. In use, placing a kettle on the heating element 2 causes the top of the support rod 5 to be pressed down, lowering the guardrail; when the user removes the kettle, the support rod 5 rises above the heating element 2 due to the elastic force of the elastic element 4. This clearly delineates the area of ​​the heating element 2 and prevents the user from reaching into the heating element area, avoiding burns. This simple mechanical structure effectively prevents users from accidentally touching the hot heating surface, the protective measures are not prone to failure, and the structure is simple with low production and maintenance costs.

[0031] It also includes a cover 6, with an opening 10 above the base 1. The cover 6 is connected to the opening 10, and a through-hole 60 is provided in the middle of the cover 6. A gap is formed between the through-hole 60 and the heating device 2 to accommodate the guardrail 3. This creates a non-scalding area outside the range of the heating device 2, further preventing burns.

[0032] It also includes a positioning spring 91 and a ball bearing 92. The side wall of the cover 2 has a spring hole 61 leading to the outer wall of the guardrail 3. One end of the positioning spring 91 is fixed relative to the cover 2, and the other end extends into the spring hole 61 and abuts against the ball bearing 92. The ball bearing 92 also abuts against the outer wall of the guardrail 3, which facilitates the smooth raising and lowering of the guardrail 3. Preferably, there are three or more sets of positioning springs 91 and ball bearings 92 arranged at equal intervals, which ensures that there is a distance between the perimeter of the guardrail 3 and the cover 2, making the raising and lowering smoother.

[0033] It also includes a column 11, the bottom of which is located on the inner bottom surface of the base 1, and the top of which supports the heating device 2. Preferably, there are three or more columns 11 arranged at equal intervals, which can effectively support the heating device 2.

[0034] The elastic element 4 is a tension spring, with one end fixed to the guardrail 3 and the other end fixed to the bracket 9. This saves space between the guardrail 3 and the bottom of the base.

[0035] It also includes a switch 8, which abuts against the guardrail 3. The switch 8 is connected in series with the heating device 2 and the power supply. When the guardrail 3 descends, it pushes the switch 8 to close, thereby connecting the heating device 2 to the power supply; when the guardrail 3 rises, it disengages from the switch 8, causing the switch 8 to open and disconnecting the heating device 2 from the power supply. This makes it easy for the heating device 2 to stop working when the kettle is removed, saving electricity and further reducing the risk of burns.

[0036] The heating device 2 has a channel 20 in the middle, and the guardrail 3 includes a base plate 30 and a surrounding edge 31 extending upward from around the base plate 30. The support rod 5 extends upward from the base plate 30 and into the channel 20. This allows the support rod 5 to be positioned in the middle of the heating device 2, making it easier to trigger the support rod 5 to descend when the kettle is placed on the heating device 2.

[0037] The switch 8 is a micro switch, and the actuating end of the switch 8 abuts against the base plate 30. This facilitates switch activation.

[0038] It also includes a crystal plate 7, which covers the top of the heating device 2. This allows the kettle to have a flat and easy-to-clean surface.

[0039] It also includes a water guide pipe 71. The crystal plate 7 has a through hole 70 that allows the support rod 5 to pass through. The water guide pipe 71 passes through the top and bottom of the heating device 2. The top of the water guide pipe 71 communicates with the through hole 70. The support rod 5 passes through the water guide pipe 71. When external water enters the through hole 70, the water flows down the water guide pipe 71 to the bottom of the heating device 2 and down the support rod 5 to the bottom of the guardrail 3, preventing water from falling into the heating device 2 and ensuring electrical safety.

[0040] It also includes a pressure ring 72, which is fixed to the heating device 2, and the middle part of the pressure ring 72 is fixed to the top of the water guide pipe 71. This facilitates the relative fixation of the water guide pipe 71 and the heating device 2.

[0041] Example 2, refer to Figure 5 Unlike Embodiment 1, the elastic element 4 is a spring, with one end abutting against the outer bottom of the guardrail 3 and the other end abutting against the inner bottom of the base 1. This saves space between the heating device 2 and the guardrail 3.

[0042] This product can be used on cooking appliances with heat sources, such as electric ceramic stoves and electric baking pans.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
