Description

Low-power dehumidifier

[ technical field ] A method for producing a semiconductor device

The utility model relates to a low-power dehumidifier.

[ background of the invention ]

Because of the reasons such as vapor condensation effect or pipeline vapor leakage for semi-sealed cabinet body such as cupboard or bathroom cabinet in the family is inside easily to receive the influence of moisture, thereby breed mould, produce bad smell or damage harmful effects such as inside article. People can select products such as an electric heating type dehumidifier or a chemical type moisture absorption box and the like to expel moisture in the cabinet body.

The electric heating dehumidifier generally comprises a power plug, an electric heating body and a shell, wherein the power plug is directly connected to the electric heating body through a power line and is plugged into a socket of commercial power to work. Electric heating driverThe humidifier reduces the relative humidity of the air in the cabinet by heating the air in the cabinet, and utilizes the hot air to generate positive pressure to lead the air in the cabinet and the outside air to carry out convection ventilation and the like to realize the dehumidification effect. The interior space of a typical cabinet sink or bathroom cabinet is small, typically less than 0.25m³The electric heating dehumidifier can realize the effect only by low power, and the output power is more than 10W through experimental analysis.

In the prior art, the electric heating body materials of the electric heating dehumidifier generally comprise PTC and alloy. The PTC material has the defect of thermal attenuation, namely, the heating power is rapidly reduced along with the increase of the service time, and the long-term working stability is poor. There is still a need for improvement in several aspects of the electric heating and humidity-driving device using alloy electric heating elements.

For a purely resistive circuit, ohm's law applies, namely: p is U²P is heating power, U is voltage, if commercial power is used, the voltage is 220V; r is resistance, and the nichrome heating wire has the temperature resistant height, advantages such as long-term operation is stable, and is general, domestic electric heating product uses this material as the heat-generating body more, and nichrome wire resistivity is less along with temperature variation, according to the formula: s is rho L/R, S is the cross section area of the heating wire, rho is the resistivity, and the resistivity of the nichrome wire is 1.0 multiplied by 10^-6Omega.m and L are the lengths of the electric heating wires, the total length of the electric heating wire loop takes 1.2m, and R is resistance; the section of a common heating wire is circular, and the wire diameter of the heating wire is calculated according to the sectional area of the heating wire:

d is the wire diameter, S is the section area of the electric heating wire, and pi is the circumference ratio.

Through calculation, under the condition of using 220V mains supply and the length of the electric heating loop, when the output power of the electric heating humidity expeller is 11W, 15W and 20W respectively, the wire diameters of the electric heating wires are 0.019mm, 0.022mm and 0.025mm respectively. Under the current general production technical conditions, the production of the nichrome heating wire with the wire diameter in the range is difficult to realize high yield and low cost.

Furthermore, the heating wires of the electric heating dehumidifier in the prior art generally adopt crimping terminal connection and heat-shrinkable sleeve packaging, so that the standardized operation of the electric heating wires in the wire diameter range is difficult to realize, poor contact or damage of the heating wires is easy to cause, the standardized wiring and packaging operation is difficult to ensure the long-term stable and safe operation of the product.

The heat shrinkable tube which is difficult to be subjected to standardized operation is placed at a high temperature for a long time, and is easy to age until the heating wire is contacted with air, so that the oxidation and aging of the heating wire are accelerated, and the service life of a product is influenced.

In addition, the low-power equipment directly uses the commercial power, so that the actual output power is easily influenced by surge impact or voltage variation, and even potential safety hazards such as explosion or fire exist.

The heating wires with thicker wire diameters are adopted, so that the production and the manufacture can be better and the quality can be better ensured, but according to ohm's law, the obvious output power can be greatly increased, and in daily life, the steam condensation effect or the steam leakage of the pipeline and other conditions can continuously occur, so that the electric heating dehumidifier generally needs to be continuously electrified to work, and the electric heating dehumidifier consumes more power and increases the life cost.

In view of the above, the present invention provides a new technical solution.
