Problems solved by technology

During the assembly process of the heater, the fan, motor, motor bracket, heating element and heating element bracket need to be assembled into the body separately, which has complex production process, low assembly efficiency, high cost and easy to cause product quality problems, etc. defect
In addition, the power adjustment of the existing heater has only 2 or 3 gears, the range of power adjustment is narrow, and the power span between each gear is large, which is not conducive to energy saving

Embodiment Construction

[0020] The following examples are further explanations and supplements to the present invention, and do not constitute any limitation to the present invention.

[0021] like figure 1 , figure 2 As shown, the variable power heater core assembly of the present invention includes an air duct shell 10, a fan 20, a PTC heating component 30, a microprocessor 40 and a motor (not shown in the figure). The air duct casing 10, the fan 20, the PTC heating component 30, the microprocessor 40 and the motor are integrated into one body.

[0022] like figure 1 , the core assembly of the heater is to integrate the air duct shell 10, the fan 20, and the PTC heating component 30 through buckles and fasteners, wherein the fan 10 and the air duct shell 20 are buckled and fastened. , the air duct shell 10 and the PTC heating component 30 are fastened and tightly connected.

[0023] like figure 2 , the air duct shell 10 is a rectangular frame-type shell, which is composed of a frame 15 and a...

Abstract

A warm air blower core assembly having variable power comprises an air flue shell, a draught fan, a PTC heating assembly and a microprocessor which are integrated, wherein the PTC heating assembly is arranged on the front side of the air flue shell, the draught fan is arranged on the rear side of the air flue shell and is connected with a motor, the PTC heating assembly is connected with the PWM port of the microprocessor, the motor is connected to the PTC port of the microprocessor, a PWM controller is arranged in the microprocessor which is used for regulating the speed of the motor through the PWM controller, and the rotating speed of the draught fan and the output power of the PTC heating assembly are changed through changes of the speed of the motor. According to the warm air blower core assembly, all members of a warm air blower core are integrated, the assembly which can be directly arranged and used is formed, the warm air blower can be conveniently and rapidly assembled through the warm air blower core assembly, and therefore production efficiency of the warm air blower is greatly improved, and the quality of the warm air blower can be effectively guaranteed. The speed of the motor is regulated through the PWM controller, the power regulating range of the warm air blower is effectively enlarged, the power span between every two gears is small, and therefore electricity is effectively saved.

Description

【Technical field】 [0001] The invention relates to a heater, in particular to a variable power heater core assembly with adjustable output power. 【Background technique】 [0002] At present, various types of air-conditioning equipment, such as air conditioners, electric fans, heaters, air-conditioning fans, humidifiers, etc., are widely used in people's lives. Cooling realizes temperature adjustment, and the heater is to increase the indoor temperature by heating the inhaled air through its electric heating device and sending it out. At present, air heaters are widely used in indoor heating in winter because of their small size, ease of movement, and good heating effects. Existing heaters generally include a body, a PTC heating component, an air duct shell and a wind wheel component. After the heater is energized, the PTC heating element heats the air entering through the air inlet, and the hot air is blown out from the air outlet through the wind wheel assembly. All parts ...
