sensitive switches

In order to avoid the condensation inside the car, it is preferable that the temperature adjusting device is installed on the outer surface of a car plate of the elevator car, the radiator is arranged on the side of the hoistway, the heat of the temperature adjusting device is radiated by using the airflow of the hoistway, that is, the unnecessary heat can be discharged to the hoistway, and the necessary heat is transmitted to the inside of the car. The control power module can convert the on-board AC220V elevator power to a power supply that provides the appropriate voltage for each thermostat.

The control unit 32 includes a control module 321, a conversion circuit 322 and an input connector 323, the conversion circuit 322 and the control module 321 are electrically connected to the control power module 2 through the input connector 323, and the conversion circuit 322 is electrically connected to the semiconductor refrigerator 35 and the temperature sensing switch 34. Specifically, the control module can be realized by adopting a PWM controller, a cheap singlechip or integrated circuits such as LM555, LM3842 and the like to form a loop; the switching circuit can be controlled by a relay to be positively or negatively connected with the semiconductor refrigerator for supplying power. Further, the switching circuit 322 is electrically connected to a fuse 324.

The control power supply module 2 comprises a circulation control circuit 21, a change-over switch 22 and six output connectors 23, the circulation control circuit 21 is electrically connected with the elevator power supply 4 through the change-over switch 22, and the circulation control circuit 21 is respectively electrically connected with the temperature adjusting devices 3 through the output connectors 23. Specifically, the control power module adopts a parallel electrical connection mode of power supply circuit supply. The circulation control circuit can be realized by a low-frequency vibration circuit (such as an LM555 integrated circuit) and a circulation circuit (such as a CD4017 integrated circuit) through a common triode (such as an 13007 triode) and the like.

The circulation control circuit can be provided with a circulation power supply output mode of 1 path or more than 1 path, and can continuously and circularly distribute power to each temperature adjusting device. For example, DC60V/3A can only be matched with 1 group of 5 serial semiconductor refrigerators, if 2 groups to 6 groups are matched in parallel, the power supply is seriously insufficient when 5 serial semiconductor refrigerators are matched in each group, and the normal operation can not be realized. At this time, the power supply of DC60V/3A can be continuously distributed to the semiconductor refrigerators of 2-6 groups by using the circulation control circuit, the power supply only supplies 1 group of 5 semiconductor refrigerators connected in series to work, thus, the semiconductor refrigerator of each group only obtains 1/2-1/6 of the original total power supply, and the advantage is that more than 30 semiconductor refrigerators can be driven even under the capacity of AC220V/1A power line. More specifically, in this embodiment, the circulation control circuit sets 6 circulation power supply outputs, the power supply respectively circulates and supplies power to six temperature adjusting devices after voltage transformation, only one of the temperature adjusting devices is supplied with power at a time, and the power supply only has 1/6 because the temperature adjusting device has energy storage, but still maintains the temperature adjusting function, and ensures that the power line is in a low-current working state for a long time.

The temperature sensing switch can automatically recover. When the temperature is higher, if the sensed temperature is higher than 30 ℃, the high-temperature action sensing switch is conducted to supply power to the semiconductor refrigerator to work and reduce the temperature; when the temperature is lower, if the sensed temperature is lower than 10 ℃, the low-temperature action sensing switch is conducted, and power is reversely supplied to the semiconductor refrigerator to work for heating. When the temperature control device is installed, one temperature sensing switch can be installed at the upper end of the heat conduction fixing plate, and the other temperature sensing switch is installed at the lower end of the heat conduction fixing plate, so that the temperature control effect can be optimized.

In this embodiment, as shown in fig. 1 to 3, a plurality of vertically distributed slots 12 are provided on an outer surface of a wall 113 of the car plate 11, and clamping edges 121 capable of being clamped with the heat-conducting fixing plate 31 are provided on two sides of the slots 12.

After the temperature adjusting device is clamped and inserted into the clamping groove, the spring piece provides extrusion force by utilizing the elastic deformation of the spring piece, so that the heat conducting fixing plate is tightly attached to the car plate.

With reference to fig. 1, 3 and 4, in order to be able to accelerate the heat dissipation, in some more specific embodiments the temperature-regulating device 3 further comprises at least one heat-dissipating fan 37. Specifically, two heat dissipation fans 37 are mounted on the heat sink 33, and the heat dissipation fans 37 are electrically connected to the control unit 32.

It should be noted that the number of the semiconductor refrigerators 35 is not limited to 5, and the number may be adjusted according to actual requirements.

As shown in fig. 5, during normal operation, the circulation control circuit 21 sets 6 circulation power supply outputs, the elevator power supply 4 is transformed, and then the circulation control circuit 21 is used to cyclically supply power to six temperature adjusting devices 3, only one temperature adjusting device 3 is supplied at a time, and the temperature adjusting devices have energy storage, so that the power supply is only 1/6, but the temperature adjusting function is still maintained, and the power line is ensured to be in a low-current working state for a long time. When the ambient temperature is high, if the sensed temperature is higher than 30 ℃, the high-temperature action sensing switch is turned on to supply power to each semiconductor refrigerator 35 to work and reduce the temperature; when the ambient temperature is low, such as the sensed temperature is lower than 10 ℃, the low-temperature action sensing switch is turned on, and power is reversely supplied to the semiconductor refrigerator 35 to work for heating. Therefore, the effects of low energy consumption and temperature regulation are achieved by configuring the plurality of temperature regulating devices 3 and matching the control power supply module 2, and the elevator car temperature regulating device has the advantages of light weight and low power consumption, effectively reduces the cost for realizing, using and maintaining the temperature regulating function of the elevator car, is convenient to install, and can provide more comfortable product service for users.
