P.29
The material of door hook is zinc alloy. As well hinge, the material of the hinge cap is
POM, and the cap set in the pins of hinge ends.
The door lock control the door after installing it correctly, the clasp of door lock enter
the mouth of the plate front and then they are fixed with screw to avoid scratch between
the door hook and the cabinet. After power supply, door hook will be locked and the door
can’t be opened.
4.14 Gasket
Gasket is injected molding with EPDM which has
many properties such as the high temperature,
corrosion resistance, anti-aging.
The gasket of Midea washing machine has
processed using advanced technique and it has
very well performance and beautiful color. What
is more, gasket achieves the goal of flexible
connectivity between cabinet and tub.
4.15 Door lock
Door lock is the device that is self- locking during
electricity and feedback signal to the PCB panel.
Delay function: the door can be opened after the
unit is off in two minutes.
4.16 NTC temperature sensor
NTC can detect the temperature range from -5
℃
to 103
℃
. The heating function stops in the
condition of fault (open or short circuit).
Change the NTC before loose the crimpling
device.
4.17 Heater
The body of heater is the heating pipe of stainless steel, and its insulation is magnesium
oxide powder and the core is the heating filament. The airproof of heater is EPDM which
has many properties such as the high temperature, corrosion resistance, anti-aging.
The stainless steel heating pipe is welded using sub-arc welding and Seamless Detection.
And then intercept set length to install the heating filament and fill magnesium oxide
powder, and then tamped through vibration. Finally, a diameter of 12mm heating pipe
compressed into 8mm with horizontal compression technology, and that is strictly ensure
the full magnesium oxide powder tamped and the quality of welds.The heater is fastened
on the tub with bolt.
Electrical principle:
Heater uses power of 220V voltage and 50Hz frequency. Due to the rated current is less
than 10A, the most power of washing machine is less than 2200 watts. Reducing the other
Harness plug
