Abstract

A negative pressure type drying machine includes a wheeled machine base carrying an drying chamber that has the peripheral walls respectively formed of high transmittance glasses, a hygrometer/thermometer for measuring the temperature and humidity in the drying chamber, an electric heater mounted in the drying chamber at the bottom for heating the air inside drying chamber, a high pressure blower for drawing air out of the drying chamber to produce a negative pressure in the drying chamber, and a control system mounted in the wheeled machine base below the drying chamber for controlling the operation of the electric heater and the high pressure blower.

Claims

1. A negative pressure type drying machine comprising:

a machine base;

an enclosed drying chamber installed in a top side of said machine base, said drying chamber having a plurality of peripheral walls respectively formed of high transmittance glasses;

a hygrometer/thermometer adapted to detect temperature and humidity in said drying chamber;

an electric heater mounted in a bottom side of said drying chamber and adapted to heat the air inside said drying chamber; and

a control system mounted in said machine base at a bottom side below said enclosed drying chamber, said control system comprising a control panel and adapted to control the operation of said electric heater;

wherein a high pressure blower is electrically connected to said control panel and adapted to draw air out of said enclosed drying chamber to further produce a negative pressure in said enclosed drying chamber, said high pressure blower having an air input port connected to the inside of said enclosed drying chamber through an air;

said control panel comprises a plurality of control buttons respectively electrically connected to said electric heater and said high pressure blower to control on/off of said electric heater and said high pressure blower.

2. The negative pressure type drying machine as claimed in claim 1, wherein said machine base has a plurality of rollers pivotally provided at a bottom sides thereof for moving.

3. The negative pressure type drying machine as claimed in claim 1, wherein said drying chamber has an inside wall surface thereof coated with a layer of photocatalyst paint.

4. The negative pressure type drying machine as claimed in claim 1, wherein said drying chamber has reflecting steel plates provided at an inner side of bottom and back walls thereof.

5. The negative pressure type drying machine as claimed in claim 1, wherein said high pressure blower is mounted in said machine base at a bottom side of said enclosed drying chamber.
