Description

Microwave disinfecting drying machine

Technical field

The utility model relates to a kind of equipment of sterilizing, drying, especially a kind of microwave disinfecting drying machine that is used for sterilizing, drying bed clothes, clothing for hospital, hotel, school, laundromat etc.

Background technology

The existing equipment that is used for sterilizing, drying bed clothes, clothing is vacuum boiler.When sterilizing, drying, earlier bed clothes or clothing are put into vacuum boiler, the pass is promptly inwardly sent into steam behind the door, bed clothes or clothing is carried out pasteurization, connects vacuum again after sterilization finishes, bed clothes or clothing are carried out vacuumize.The shortcoming of existing sterilizing, drying equipment is: 1) it is long to the time that bed clothes, clothing etc. carry out sterilizing, drying, is example with bed clothes, at every turn with consuming time more than eight hours; 2) used equipment is except vacuum boiler, at least also must dispose vacuumizing device and the equipment that steam is provided, so investment cost of equipment height, daily for providing the spent electric energy of steam and vacuum suction many, and the floor space of entire equipment or take up room bigger.

It contains cabinet, control panel Chinese patent 02272837.6 disclosed " a kind of novel microwave dried disinfecting cabinet ", and comprises that antenna, magnetron, air channel plate, high-tension transformer, blower fan, rectifier, capacitor and an energy scatter the external wind passage mouth that offers for sale with the microwave that discharges on the antenna.Its shortcoming is: 1) it is when being used for the microwave drying of large-scale bed clothes, because of being difficult for evenly heating and not having humidity-discharging device again, so the effect of sterilizing, drying is undesirable; 2) its blower fan just plays the cooling to its inner heat assembly, rather than to the cooling of bed clothes, clothing, therefore more is difficult to their dehumidifying; 3) its cabinet is not provided with anti-microwave and reveals the chamber, therefore must close the door could the microwave operation, and must stop work in the taking-up of bed clothes, clothing or when putting into, and the intermittent time that should stop work will surpass the time of its normal microwave operation, so its microwave drying efficiency of operation is low, also take very much artificial.

Summary of the invention

The utility model is to overcome existing shortcoming in the above-mentioned prior art, a kind of microwave disinfecting drying machine that but effective and continuous operation, speed are fast, efficient is high of sterilizing, drying is provided, and makes it have that equipment investment is taken up an area of with low, daily less energy consumption, equipment or the characteristics such as little that take up room.

The utility model microwave disinfecting drying machine, it contains casing, the microwave working chamber that comprises magnetron, waveguide, transformer, axial flow blower that in casing, is provided with, be characterized in: having the aspirating chamber, the casing that are communicated with the microwave working chamber in its casing is that anti-microwave is revealed the chamber in the entrance point and the chamber, port of export place of clothing, and be provided with the conveyer of shuttling movement between entrance point, the port of export and the microwave working chamber, this device comprises carrier bar mechanism and the pressure zone mechanism that can carry the clothing motion synchronously secretly.

It is the inner chamber of the angle bar of the fixed nonmagnetic substance one by one of casing inner wall that above-mentioned anti-microwave is revealed the chamber, and the shape of cross section of angle bar is a square.

The utility model microwave disinfecting drying machine also has temperature detect switch (TDS) in its casing, too high to prevent the temperature in the microwave working chamber; And casing is provided with display, to monitor the operation in the microwave working chamber.

The beneficial effects of the utility model are: 1) the utility model microwave disinfecting drying machine is when carrying out the microwave sterilization oven dry to bed clothes, each institute took time maximum 5 minutes, therefore solved existing vacuum boiler to oversize problem of the time of bed clothes sterilizing, drying, and required auxiliary device is few, investment cost of equipment is low, equipment takes up an area of less, daily power consumption is little; 2) compare with existing microwave drying disinfection cabinet, because of homogeneous heating and again can ventilation dewetting, so sterilizing, drying effective, efficient is high; 3) the anti-microwave that is provided with on housing is revealed the chamber, the import and export end that can make clothing changes the operation of opening the door into by the operation of closing the door of existing microwave drying disinfection cabinet, and behind the conveyer of configuration cycles motion, make the clothing of oven dry subject to sterilization enter the microwave working chamber automatically, after the microwave sterilization oven dry, directly exporting from the port of export from entrance point; Thereby the entire job process is further accelerated continuously the speed of the sterilizing, drying of clothing such as bed clothes, and laborsaving, saving of labor.
