Technical Field

[0001] This utility model relates to the field of single-phase regulation technology, and in particular to a three-level adjustable single-phase energy-saving device. Background Technology

[0002] A three-speed adjustable single-phase energy-saving device is an electronic control device mainly used for single-phase AC motors (most commonly electric fans, including household table fans, floor fans, ceiling fans, etc.). It achieves high, medium, and low wind speed adjustment by changing the voltage applied to the motor, thereby saving energy in the process.

[0003] The existing three-level adjustable single-phase energy-saving device has shortcomings in terms of high heat dissipation and high stable operation, and its practicality needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a three-level adjustable single-phase energy-saving device that can perform efficient heat dissipation and thus operate with high stability, making it highly practical.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A three-speed adjustable single-phase energy-saving device includes a housing. At each of the four corners of the inner end face of the housing, a mounting post is provided, and a thyristor voltage regulating circuit board is mounted at the end of each mounting post. A heat sink is mounted on the thyristor voltage regulating circuit board. A mounting groove is provided on the side surface of the housing, and the heat dissipation fins of the heat sink penetrate the interior of the mounting groove. A cover plate is installed at the port of the housing, and a mounting hole is provided on the outer surface of the cover plate, with a fan mounted at the mounting hole.

[0007] By adopting the above technical solution, the fan can be started during operation, and the airflow generated by the fan can be used to dissipate heat from the internal structure of the casing, thus achieving efficient and stable operation.

[0008] Furthermore, a plurality of exhaust channels are provided on the side surface of the housing, and the exhaust channels are distributed between the heat dissipation fins of two adjacent heat sinks.

[0009] By adopting the above technical solution, it is ensured that the flowing air can effectively pass through the interior of the casing.

[0010] Furthermore, a gear knob is mounted on the outer surface of the thyristor voltage regulating circuit board, the operating end of the gear knob is located outside the housing, and a gear indicator is provided on the side surface of the housing.

[0011] By adopting the above technical solution, gear adjustment can be effectively performed.

[0012] Furthermore, a mounting groove is provided on the side surface of the housing, and a wiring terminal is installed inside the mounting groove.

[0013] By adopting the above technical solution, it is easy to make electrical connections to the device.

[0014] Furthermore, an air vent is provided between the upper edge of the radiator and the inner wall of the housing.

[0015] By adopting the above technical solution, effective gas-guided operation can be performed.

[0016] Furthermore, a mounting plate is integrally connected to the lower edge of the symmetrical side surface of the housing.

[0017] By adopting the above technical solution, the entire device can be installed and operated effectively.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] This invention allows for speed adjustment via a gear selector knob and voltage control via a silicon controlled rectifier (SCR) circuit board, thereby achieving energy-saving operation. The fan then enters the housing, and the flowing air passes through the air inlet and exhaust channel. This airflow effectively improves the heat dissipation performance of the radiator, enhancing the device's long-term operational stability. The high heat dissipation performance also reduces the device's energy consumption, further contributing to energy savings. Attached Figure Description

At each of the four corners of the inner end face of the housing 1, a mounting post is provided, and a thyristor voltage regulating circuit board 8 is mounted at the end of each mounting post. A heat sink 9 is mounted on the thyristor voltage regulating circuit board 8. A mounting groove is provided on the side surface of the housing 1, and the heat dissipation fins of the heat sink 9 penetrate through the interior of the mounting groove. A cover plate 2 is installed at the port of the housing 1, and a mounting hole is provided on the outer surface of the cover plate 2, with a fan 3 mounted at the mounting hole. Multiple exhaust channels 10 are provided on the side surface of the housing 1, distributed between the heat dissipation fins of adjacent heat sinks 9. A vent 11 is provided between the upper edge of the heat sink 9 and the inner wall of the housing 1. A speed adjustment function is mounted on the outer surface of the thyristor voltage regulating circuit board 8. The gear selector knob 5 has its operating end located outside the housing 1. A gear position indicator 6 is provided on the side surface of the housing 1. During operation, the gear selector knob 5 can be used to adjust the gear position. When adjusting, the gear position can be determined by referring to the gear position indicator 6. Then, the voltage is controlled by the thyristor voltage regulating circuit board 8 to achieve speed regulation and thus energy-saving operation. Next, the fan 3 is started. The rotation of the fan 3 allows external air to enter the interior of the housing 1. The flowing air then passes through the air guide port 11 and through the interior of the exhaust channel 10. The flowing air can effectively improve the heat dissipation performance of the radiator 9, effectively improve the working stability of the device during long-term control, and the high heat dissipation performance can effectively reduce the energy consumption of the device itself, thus further saving energy.

A mounting plate 7 is integrally connected to the lower edge of the symmetrical side surface of the housing 1, and the wiring terminal 4 can be used to realize convenient electrical connection operation.

[0027] Working principle: During use, the device is installed in the designated location using the mounting plate 7, and then an effective electrical connection is achieved through the wiring terminal 4. After the connection is completed, normal use can begin. During operation, the gear position is adjusted using the gear knob 5. The gear position can be determined by referring to the gear indicator 6. The voltage is then controlled using the thyristor voltage regulating circuit board 8 to achieve speed regulation and thus energy-saving operation. Next, the fan 3 is started. The rotation of the fan 3 allows external air to enter the interior of the housing 1. The flowing air then passes through the air inlet 11 and through the interior of the exhaust channel 10. The flowing air effectively improves the heat dissipation performance of the radiator 9, which effectively improves the working stability of the device during long-term control. The high heat dissipation performance effectively reduces the energy consumption of the device itself, thus further saving energy.
