Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, and in particular relates to a range hood that is linked to the start and stop of the stove. Background Technology

[0002] Existing range hoods and cooktops are controlled separately, meaning they are controlled independently. Because the cooktop panel has control knobs, cleaning can easily become difficult, creating hard-to-reach areas and causing inconvenience for users. Furthermore, controlling the range hood and cooktop separately also presents a challenge for users. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a stove that is easy to clean and can reduce the cleaning dead corners on the stove panel.

[0004] To solve the above-mentioned technical problems, this utility model provides a range hood that is linked to a cooktop for start-stop operation. The range hood includes a cooktop for use with it, and a proportional valve is provided inside the cooktop. The proportional valve can control the start-stop operation of the cooktop and adjust the fire intensity. Both the range hood and the cooktop are provided with radio frequency modules inside their respective interiors. The radio frequency modules can transmit or receive signals, and the range hood controls the proportional valve of the cooktop through the radio frequency modules.

[0005] Preferably, an infrared temperature sensor is provided at the bottom of the range hood, which is used to detect the temperature of the pot body.

[0006] Preferably, the smoke machine is equipped with a buzzer for issuing an alarm.

[0007] Preferably, a stove temperature sensor is provided at the burner cap of the stove, and the stove temperature sensor is used to detect the temperature of the bottom of the pot.

[0008] Preferably, the range hood is equipped with an electromagnetic coil winding, and the cooktop is equipped with a reverse electromagnetic coil winding and a capacitor.

[0009] Preferably, the range hood is equipped with an anti-collision device, which includes an outer cover that can slide relative to the range hood housing, and the range hood housing and the outer cover are provided with elastic sealing barriers.

[0010] Preferably, the inner side of the range hood housing is provided with a balancing shaft that can rotate relative to it. The balancing shaft is arranged laterally on the inner side of the range hood housing. At least two sets of balancing gears are fixedly connected to the balancing shaft. The balancing gears are distributed on both sides of the outer cover. The balancing gears mesh with a balancing rack. One end of the balancing rack meshes with the balancing gear, and the other end of the balancing rack is connected to the outer cover.

[0011] Preferably, a baffle is fixedly connected to the inner side of the range hood housing, and an elastic element is provided between the baffle and the outer cover.

Detailed Implementation

[0022] See attached document Figure 1 Appendix Figure 2 This utility model provides a range hood that is linked to a cooktop for start-stop operation. It includes a range hood 1, such as a kitchen range hood, and a cooktop 2 paired with it. The cooktop 2 has a proportional valve inside, which controls the start-stop operation of the cooktop 2 and adjusts the heat level. Both the range hood 1 and the cooktop 2 have radio frequency (RF) modules inside, capable of transmitting or receiving signals. The range hood 1 controls the proportional valve of the cooktop 2 via the RF module. An infrared temperature sensor 101 is located at the bottom of the range hood 1, used to detect the temperature of the pot. The infrared temperature sensor 101 can send signals to the range hood 1. The range hood 1 also has a buzzer inside for issuing alarms. When a dry-burning signal is received, the buzzer automatically sounds and sends a signal to the cooktop 2, controlling the proportional valve of the cooktop 2 to cut off the gas supply.

[0023] This invention integrates the control switch of the traditional cooktop 2 into the paired range hood 1 through the above structure, eliminating the traditional cooktop knob. Controlling only the range hood 1 controls the start / stop and flame adjustment of the cooktop 2. A proportional valve is installed inside the cooktop, and an radio frequency (RF) module is added. The range hood 1 has an RF transmitter or receiver module. When the start / stop button for cooktop 2 in the range hood 1 switch is pressed, cooktop 2 receives the RF signal, its internal electric ignition module operates, and the proportional valve opens the gas pipe, supplying gas to cooktop 2. At this time, cooktop 2 generates a flame, achieving ignition. When the flame adjustment button for cooktop 2 in the range hood 1 switch is pressed, cooktop 2 receives the signal and automatically adjusts the proportional valve's operating state, thereby adjusting the gas intake to achieve flame adjustment. When the range hood's infrared sensor 101 detects that the pot temperature is too high, for example, exceeding 300℃, it considers the cooktop to be in a dry-burning state. At this time, it sends a signal to the range hood. The range hood has an internal buzzer; upon receiving the dry-burning signal, it automatically sounds an alarm and sends a signal to the cooktop, controlling the proportional valve to cut off the gas supply. Through the above structure, this utility model controls the stove 2 through the range hood 1, eliminates the control knob on the stove 2, reduces the hardware configuration of the stove, reduces the cleaning dead corners of the stove panel, and facilitates the cleaning of the stove panel.

[0024] Preferably, a stove temperature sensor 201 is installed at the burner cap of the stove to detect the temperature of the bottom of the pot. When the stove temperature sensor 201 detects that the temperature of the bottom of the pot is too high, for example, above 300°C, it is considered that the stove 2 is in a dry burning state. At this time, a signal is sent to the range hood 1 to control the proportional valve of the stove 2 to cut off the gas supply.

[0025] Preferably, the range hood 1 is equipped with an electromagnetic coil winding, and the cooktop 2 is equipped with a reverse electromagnetic coil winding and a capacitor. When the range hood 1 is turned on, the electromagnetic coil of the range hood 1 is energized at the same time. At this time, the reverse electromagnetic coil winding in the cooktop 2 generates current, which is used to power the proportional valve and the cooktop temperature sensor 201 of the cooktop 2, so as to achieve the function of wireless transmission.

[0026] See Figures 3 to 5 The range hood 1 is equipped with an anti-collision device, which includes an outer cover 301 that can slide relative to the range hood housing 102. The range hood housing 102 and the outer cover 301 are equipped with an elastic sealing barrier 302. One end of the elastic sealing barrier 302 is connected to the range hood housing 102, and the other end of the elastic sealing barrier 302 is connected to the outer cover 301. The elastic sealing barrier 302 ensures that the outer cover 301 can slide relative to the range hood housing 102 while blocking the gap between the two to prevent oil stains from entering the inside of the range hood 1.

[0027] The inner side of the range hood housing 102 is provided with a balancing shaft 103 that can rotate relative to it. The balancing shaft 103 is arranged laterally on the inner side of the range hood housing 102. At least two sets of balancing gears 104 are fixedly connected to the balancing shaft 103. The balancing gears 104 are distributed on both sides of the outer cover 301. The balancing gears 104 mesh with balancing racks 105. One end of the balancing rack 105 meshes with the balancing gears 104, and the other end of the balancing rack 105 is connected to the outer cover 301. Because the elastic sealing barrier 302 has a certain elasticity, when the outer cover 301 moves relative to the range hood housing 102, the outer cover 301 can be reset by the action of the elastic sealing barrier 302.

[0028] Preferably, a baffle 106 is fixedly connected to the inner side of the range hood housing 102, and an elastic element 108 is provided between the baffle 106 and the outer cover 301. A guide shaft 107 is fitted inside the elastic element 108, and the guide shaft 107 slides relative to the baffle 106.

[0029] Through the above structure, under normal conditions, the outer cover 301 is separated from the range hood housing 102, and the elastic element 108 is in a freely extended state. When the user bumps into the outer cover 301, the elastic sealing barrier 302 has a certain elasticity, so it can deform to absorb the impact force. At the same time, after being subjected to force, the outer cover 301 can drive the balance gear 104 to rotate through the balance rack 105. The balance gear 104 drives the balance shaft 103 to rotate, and the balance shaft 103 drives all the balance gears 104 connected to it to rotate. Each balance gear 104 can drive the outer cover 301 to move relative to the range hood housing 102 through the balance rack 105 it meshes with, so that the outer cover 301 as a whole moves relative to the range hood housing 102, further absorbing the impact generated during the collision and preventing the user from being directly hit.

[0030] See Figure 5The inner side of the elastic sealing barrier 302 is provided with a barrier groove 303, which is located between the outer casing 102 of the smoke machine and the outer cover 301. When the outer cover 301 is subjected to external force, the weakest part of the elastic sealing barrier 302, namely the barrier groove 303, deforms first, increasing the flexibility of the elastic sealing barrier 302 in deforming under force.

[0031] This invention, through the above structure, eliminates the need for a control knob on the cooktop. Control of the cooktop is achieved through the range hood. During cooking, simply pressing the cooktop on-hook button on the range hood turns on the cooktop. The radio frequency module controls the cooktop's operation and power adjustment. If the oil in the pan boils and splashes or becomes dry-burning, a temperature sensor transmits a signal to the range hood, triggering an alarm and cutting off the gas supply. The cooktop no longer uses battery power, avoiding the need for frequent battery replacements. This invention eliminates the traditional cooktop control knob, integrating it into the range hood for unified control of both the cooktop and range hood. This simplifies operation for consumers. The addition of a temperature sensor prevents dry-burning and incorporates opposing electromagnetic coils within the cooktop and range hood for wireless transmission.

Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
