Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to an automatic heating electric ceramic stove. Background Art

[0002] A ceramic stove is a heating device that converts electrical energy into heat through the thermal effect of electric current. The heat is generated by the nickel-chromium wire in the stovetop, which emits infrared radiation as it heats up. This technology accelerates heating, ensures a healthy and safe heating process, and eliminates electromagnetic radiation hazards, making it highly popular with consumers. Currently, there are ceramic stoves on the market specifically designed for boiling water or making tea. A teapot is placed on the stovetop and the stove is powered on by pressing a button or turning a knob. After heating is complete, the stove needs to be powered off again by pressing the button or turning the knob. This switching method requires frequent button or knob activation, which is inefficient. Therefore, consumers are urgently seeking an automatic heating ceramic stove. Simply placing the teapot on the stovetop automatically activates the stovetop, eliminating the need for a button or knob to trigger the power on. This convenient and efficient design allows the stove to automatically power on and heat up when the teapot is removed.

[0022] The present invention provides an automatic heating electric ceramic stove. To clarify the objectives, technical solutions, and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0023] See also Figure 1-Figure 4 The present invention provides an automatic heating electric ceramic stove, comprising a base 1, a movable stove body 2 that can slide up and down relative to the base, a panel 3, a circuit control assembly 4, and a heating plate 5. The movable stove body 2 is provided with upper and lower openings, and the panel 3 is provided to cover the upper opening of the movable stove body 2. The movable stove body 2, the panel 3, and the base 1 form a chamber A for accommodating the circuit control assembly and the heating plate; the circuit control assembly includes a circuit board (not shown) fixedly provided on the base and a trigger switch 41, and the circuit board and the trigger switch are electrically connected; the movable stove body 2 is provided with a push rod 21 for triggering the trigger switch to turn on, and the movable stove body 2 is connected to the base 1 via an elastic support assembly 6.

[0024] The following briefly describes the operating principle: When a teapot is placed on the panel 3 of the movable insulator, the movable insulator 2 moves vertically downward under the action of gravity, causing the bottom end of the push rod 21 to press against the trigger portion of the trigger switch 41. This triggers the switch 41, thereby closing the circuit and causing the heating plate 5 to begin heating the teapot. When the teapot is removed from the panel 3, the movable insulator 2 loses its weight, and the elastic support assembly 6 pushes the movable insulator 2 upward to its initial position. The trigger switch 41 also resets and disconnects the circuit. Compared to existing ceramic stoves, the ceramic stove provided by the present invention automatically powers on and heats simply by placing the teapot on it, without the need for a button or knob to trigger power. This is convenient and efficient. When heating is complete, the ceramic stove automatically disconnects the circuit when the teapot is removed, ensuring safety and reliability.

[0025] For details, please refer to Figure 1 and Figure 3 The elastic support assembly 6 includes at least two upper connecting columns 61 arranged on the inner wall of the movable furnace body, and lower connecting columns 62 arranged on the base 1 with the same number and one-to-one corresponding to the upper connecting columns; each upper connecting column 61 is respectively provided with a first threaded hole 63; each lower connecting column 62 is respectively provided with a countersunk through hole 64; the countersunk head 64a of the countersunk through hole 64 is located at the connection between the lower connecting column 62 and the base 1, and a first screw 65 is passed through the countersunk through hole 64 of each lower connecting column 62 from bottom to top, and the top of each first screw 65 is respectively screwed into the first threaded hole 63 of the corresponding upper connecting column 62; each first screw 65 is located at the section between the upper connecting column 61 and the lower connecting column 62, and is respectively covered with a first spring 66, the top of each first spring 66 is against the bottom surface of the corresponding upper connecting column 62, and the bottom end of each first spring 66 is against the upper surface of the corresponding lower connecting column 62. On the one hand, the first screw 65 is slidably connected to the countersunk through-hole 64, guiding the movement of the movable furnace body 2 and reducing its movement deviation. On the other hand, when the teapot is removed, the piston furnace body 2 rises due to the elastic force of the first spring 66. The head of the first screw 65 is restrained by the countersunk head 64a, preventing the movable furnace body 2 from separating from the base 1. In normal use, the total upward force exerted on the movable furnace body 2 by all the first springs 66 is greater than the combined weight of the movable furnace body 2 and the panel 3.

[0026] In this embodiment, please refer to Figure 1 There are four upper connecting posts 61, with the circumferential angle between any two of them being 90 degrees. Correspondingly, there are four lower connecting posts 62 on the base, and four corresponding first screws 65 are provided. This arrangement ensures that the movable furnace body is relatively stable during its downward movement and upward return movement, preventing it from tilting.

[0027] Preferably, see Figure 1Each upper connecting post 61 includes an upper connecting post body 61a and an upper positioning protrusion 61b disposed at the bottom end of the upper connecting post body. Each lower connecting post 62 includes a lower connecting post body 62a and a lower positioning protrusion 62b disposed at the top end of the lower connecting post body. The top of each first spring 66 is sleeved onto the corresponding upper positioning protrusion 61b, and the bottom of each first spring 66 is sleeved onto the corresponding lower positioning protrusion 62b. This arrangement allows the upper positioning protrusions 61b and lower positioning protrusions 62b to radially position the first springs 66, ensuring that each first spring 66 remains stable when compressed and prevents tilting or misalignment, thereby improving the stability of the teapot when placed on the panel.

[0028] Preferably, see Figure 1 The upper surface of each upper connecting column forms a step for supporting the panel. During assembly, the panel is placed on the step and then glued to the edge of the panel and the inner wall of the movable furnace body. It is simple and convenient.

[0029] For details, please refer to Figure 1 and Figure 3 The heating plate 5 is connected to the base 1 by at least two sets of elastic support assemblies 7. Each set of elastic support assemblies 7 includes a guide post 71 provided on the base, a connecting ear 72 provided on the upper side of the guide post, and a second spring 73 provided between the connecting ear 72 and the guide post 71. One end of the connecting ear 72 is connected to the heating plate 5, and the other end is provided with a second through hole 74. The top of the guide post 71 is provided with a second threaded hole 75. A second screw 76 is passed through the second through hole of each connecting ear 72 from top to bottom. Each second screw 76 passes through the second through hole 74 and the second spring 73 in sequence and is screwed into the corresponding second threaded hole 75. During heating, the elastic support assembly 7 presses the heating plate 5 against the bottom of the panel 3, ensuring the heating effect and reducing the heat dissipation from the gap between the heating plate 5 and the panel 3. In addition, when the teapot is placed on the panel, the panel moves downward with the movable furnace body and presses against the heating plate. The spring support assembly also acts as a buffer to prevent the panel from rigidly colliding with the heating plate.

[0030] In this embodiment, please refer to Figure 1 , there are 3 sets of elastic supporting components 7, and the circumferential angle between any two adjacent elastic supporting components is 120 degrees. This arrangement makes the heating plate more stable during the buffering and upward pressure process without tilting.

[0031] Preferably, see Figure 1Each guide post 71 includes a guide post body 71a and a positioning post 71b disposed on the top of the guide post body. The bottom of each second spring 73 is sleeved on the corresponding positioning post 71b. Through this arrangement, the positioning post 71b can radially position the second spring 73, ensuring that each second spring 73 remains stable when compressed and does not tilt or misalign, thereby improving the stability of the heating plate.

[0032] Preferably, see Figure 1 The heating plate 5 includes a heating element 51 electrically connected to the circuit board, a ceramic base 52, and a bottom shell 53 for receiving the ceramic base. The upper surface of the ceramic base 52 is provided with a circular groove 54 for accommodating the heating element. The bottom shell 53 is screwed to the connecting ear 72. The ceramic base 52 has good high temperature resistance and heat insulation performance. The ceramic base effectively isolates the heat transfer from the heating element to the bottom shell. The heating element 51 can be a heating tube, heating wire or heating sheet made of nickel-chromium material.

[0033] Preferably, see Figure 1 and Figure 4 The base is provided with a fixing seat 8 for mounting a trigger switch. The trigger switch is screwed to the fixing seat. The push rod is vertically arranged. The trigger switch is a tactile switch. The trigger portion of the tactile switch faces the push rod. The push rod presses against the trigger portion of the tactile switch to turn on the tactile switch. Once the tactile switch loses its trigger, the trigger portion automatically resets to disconnect the circuit and waits for the trigger to turn on.

[0034] Preferably, see Figure 1 and Figure 3 The bottom surface of the inner cavity of the base is provided with a mounting post (not shown), which is equipped with a temperature control switch 42 for electrical connection to the circuit board. When the circuit is connected to the heating plate 5 to achieve heating, the temperature control switch 42 constantly monitors the temperature of the oven body. When the temperature reaches a certain level, the temperature control switch disconnects the circuit to achieve over-temperature protection. When the temperature drops to a certain level, the temperature control switch automatically connects the circuit to keep the food warm.

[0035] Preferably, see Figure 1 , the side wall of the movable furnace body is provided with multiple groups of heat dissipation holes 9. Due to the provision of multiple groups of heat dissipation holes, the heat dissipation effect of the furnace body is further improved.

[0036] Preferably, see Figure 2-Figure 4The base 1 includes a disc-shaped base 11 and a plurality of legs 12 disposed at the bottom of the base. The movable furnace body 2 is cylindrical, with the lower portion of the movable furnace body 2 disposed outside the base 11. The legs 12 support the base 11, ensuring a stable position and reducing slippage. Furthermore, the legs 12 support the base 11, preventing the first screw 65 from interfering with the placement surface of the electric ceramic stove when it moves downward.

[0037] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of the present invention, and all such changes or substitutions should fall within the scope of protection of the present invention.
