Microwave clothes dryer

Abstract

The invention provides a microwave clothes dryer which comprises a cavity assembly. The cavity assembly is provided with a barrel, a rear plate and a waveguide pipe assembly. The waveguide pipe assembly is connected with the side wall of the barrel, the side wall is provided with a waveguide opening communicated with the waveguide pipe assembly, the rear plate is arranged on an opening of the barrel and connected with the barrel, and the rear plate is provided with a first air inlet. The waveguide pipe assembly is connected with the side wall, provided with the waveguide opening, of the barrel, the length of a microwave transmitting path is reduced, microwave losses are reduced, and the microwave utilization rate is increased. Furthermore, the first air inlet is formed in the position, on the opening of the barrel, of the rear plate, therefore, the air inlet area of the opening of the barrel is increased, the air resistance coefficient is greatly reduced, heat energy losses are reduced, and the heat energy utilization efficiency is improved. Meanwhile, the cavity assembly is novel in structure, reasonable in design, high in adaptability, convenient to maintain and repair and remarkable in energy saving and emission reducing effect, and the use performance of a product and user experience are improved.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a microwave clothes dryer. Background technique [0002] The microwave clothes dryer 1' is a new technical product produced by utilizing and combining the principle of microwave heating and the principle of a clothes dryer. Such as Figure 1 to Figure 5 As shown, the direction indicated by the arrow is the trajectory of the microwave and hot air. In the cavity assembly 70' of the drum 30' type clothes dryer in the related art, the microwave port 10' and the hot air source inlet 20' are arranged behind the drum 30' end, and the microwave port 10' and the hot air source inlet 20' are located on the same end face, so that the microwave and hot air enter the inside of the drum 30' from the rear end of the drum 30'. This arrangement reduces the inlet area of ​​the hot air source, making wind resistance and The loss of heat energy is large, and the drying efficiency is low; further...

Problems solved by technology

like Figure 1 to Figure 5 As shown, the direction indicated by the arrow is the trajectory of the microwave and hot air. In the cavity assembly 70' of the drum 30' type clothes dryer in the related art, the microwave port 10' and the hot air source inlet 20' are arranged behind the drum 30' end, and the microwave port 10' and the hot air source inlet 20' are located on the same end face, so that the microwave and hot air enter the inside of the drum 30' from the rear end of the drum 30'. This arrangement reduces the inlet area of ​​the hot air source, making wind resistance and The loss of heat energy is large, and the drying efficiency is low; further, the waveguide 40' is long, which prolongs the working path of microwave energy and aggravates the loss of microwave energy; the air duct path composed of air duct 50' and fan assembly 60' Long, with many bends, long working path of wind energy, high drag coefficient, and large heat loss
