Description

Technical Field

[0001] The utility model relates to the technical field of heaters, in particular to an intelligent heater. Background Art

[0002] After a vehicle has been parked for a long time, if the ambient temperature outside the vehicle is low and the temperature of the seats inside the vehicle is also low, the driver's riding comfort will be reduced. Especially in northern China, where the weather is cold, people have an even more urgent need for seat heating. Existing seat heating generally has an electric heating blanket built into the seat, and by setting a corresponding pressure sensor, the seat will only be heated when someone sits on it to reduce the waste of electricity resources. However, when heavy objects are placed on the seat, the pressure sensor will still be triggered, causing the seat to be heated even when no one is sitting on it, resulting in a waste of electricity resources.

[0013] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0014] like Figure 1 As shown, an intelligent heater includes a controller 1, a first electric heating blanket 2 and a second electric heating blanket 3. The first electric heating blanket 2 and the second electric heating blanket 3 are both provided with resistance heating wires. The controller 1 is electrically connected to the first electric heating blanket 2 and the second electric heating blanket 3. The first electric heating blanket 2 and the second electric heating blanket 3 are both arranged on a seat 4. The seat 4 has a seat surface 5 and a backrest 6 with an interlayer. The first electric heating blanket 2 is arranged in the interlayer of the seat surface 5, and the second electric heating blanket 3 is arranged in the interlayer of the backrest 6. A pressure sensor 1 7 is provided on the first electric heating blanket 2. The pressure sensor 1 7 is arranged below one end of the first electric heating blanket 2 near the backrest 6. A pressure sensor 2 8 and a pressure sensor 3 9 are provided on the second electric heating blanket 3. The pressure sensor 2 8 and the pressure sensor 3 9 are respectively arranged on the dorsal sides of the two ends of the second electric heating blanket 3. A first temperature sensor 10 is provided on the first electric heating blanket 2 and the second electric heating blanket 3.

[0015] The controller 1 can control the use of the first electric heating blanket 2 and the second electric heating blanket 3 respectively. The pressure sensor 1 7 is set on the seat surface 5 within the range of contact with the occupant's buttocks, the pressure sensor 2 8 is set on the backrest 6 within the range of contact with the occupant's waist, and the pressure sensor 3 9 is set on the backrest 6 within the range of contact with the occupant's shoulder blades. When the occupant sits on the seat 4, the occupant's buttocks will trigger the pressure sensor 1 7. As long as the occupant's waist or shoulder blade triggers at least one of the pressure sensor 2 8 and the pressure sensor 3 9, the controller 1 will control the first electric heating blanket 2 and the second electric heating blanket 3 to start working, thereby heating the seat 4. That is, the opening of the first electric heating blanket 2 and the second electric heating blanket 3 can be controlled by the pressure sensor 1 7 and the pressure sensor 2 8, or by the pressure sensor 1 7 and the pressure sensor 3 9, or by the pressure sensor 1 7, the pressure sensor 2 8 and the pressure sensor 3 9 at the same time. The first electric heating blanket 2 and the second electric heating blanket 3 cannot be heated separately.

[0016] Pressure sensor 1 7, pressure sensor 2 8 and pressure sensor 3 9 have certain pressure triggering limits, but due to different installation positions, the pressure at which each pressure sensor is triggered is also different. According to the comparison of the triggering pressures, the triggering pressure of pressure sensor 1 7 is the largest, and the triggering pressure of pressure sensor 3 9 is the smallest.

[0017] When an object is placed on the seat 4, due to the limitations of the object's height, weight and shape, it cannot effectively fit against the seat back 6 of the seat 4, making it difficult for the object to simultaneously trigger pressure sensor 1 7, and at least any one of pressure sensor 2 8 and pressure sensor 3 9. Therefore, even when an object is placed on the seat, the seat 4 can effectively prevent the first electric heating blanket 2 and the second electric heating blanket 3 from heating the seat 4.

[0018] The two first temperature sensors 10 are respectively used to detect the temperatures of the seat surface 5 and the backrest 6 of the seat 4. Since the human body also generates heat, the temperature between the human body and the seat surface 5 and the backrest 6 will gradually increase, which poses certain safety hazards and affects the riding comfort. When the temperature of the seat surface 5 is high, the first electric heating blanket 2 is controlled by the controller 1 to reduce its heating power, thereby reducing the heating temperature of the first electric heating blanket 2 and avoiding the temperature between the human body and the first electric heating blanket 2 from being too high. Similarly, when the temperature of the backrest of the seat 4 is high, the second electric heating blanket 3 is controlled by the controller 1 to reduce its heating power, thereby reducing the heating temperature of the second electric heating blanket 3.

[0019] Furthermore, both the first electric heating blanket 2 and the second electric heating blanket 3 are provided with a flexible waterproof sheet 11 to reduce the impact of spilled beverages, infiltration of rainwater, etc. on the safety of the first electric heating blanket 2 and the second electric heating blanket 3.

[0020] Furthermore, a second temperature sensor 12 for detecting the temperature outside the vehicle compartment is provided inside the seat 4 and on the controller 1. The detection end of the second temperature sensor 12 is provided outside the vehicle compartment, that is, it detects the ambient temperature of the vehicle. When the ambient temperature is lower than a predetermined value, the pressure sensor 1 7, the pressure sensor 2 8 and the pressure sensor 3 9 can be turned on and work normally. When the ambient temperature is higher than a predetermined value, the pressure sensor 1 7, the pressure sensor 2 8 and the pressure sensor 3 9 will not start working even if they are subjected to a pressure that can trigger it.

[0021] Furthermore, the first electric heating blanket 2 and the second electric heating blanket 3 are connected to the seat 4 via Velcro, which facilitates the installation and removal of the first electric heating blanket 2 and the second electric heating blanket 3.

[0022] Furthermore, pressure sensor 1 7, pressure sensor 2 8, pressure sensor 3 9 and the first temperature sensor 10 are all arranged on the symmetrical center line of the seat 4, so that pressure sensor 1 7, pressure sensor 2 8, pressure sensor 3 9 can more accurately detect the pressure from the occupant, and the first temperature sensor 10 can more accurately detect the temperature between the occupant and the seat surface 5 and the backrest 6, so as to facilitate timely adjustment of the heating power of the first electric heating blanket 2 and the second electric heating blanket 3.

[0023] This type of intelligent heater can improve the accuracy of detecting whether there is an occupant on the seat 4, and heat the seat 4 where an occupant is detected separately. It will not heat the seat 4 where no occupant is sitting or the seat 4 where objects are placed, thereby effectively reducing the waste of electricity resources.
