Washer liquid heating apparatus integrated into washer reservoir

A washer liquid heating apparatus integrated into a reservoir, comprising:

• an auxiliary tank which is integrally connected to the reservoir and in which a washer liquid inflowing from the reservoir is stored;
• a heater assembly that is integrally attached to the auxiliary tank and heats the washer liquid stored in the auxiliary tank,
• wherein the heater assembly comprises a plate-type heater that is installed in a hole of the auxiliary tank to heat the washer liquid within the auxiliary tank, and
• wherein the plate-type heater is exposed to an inside of the auxiliary tank through the hole of the auxiliary tank such that a heating surface where heating is performed heats the washer liquid within the auxiliary tank,
• wherein an input port to be fitted into a hole formed on a lower part of the reservoir is formed on an upper part of the auxiliary tank, and
• wherein a height of the input port is lower than a top height of the reservoir, so that the washer liquid within the reservoir inflows into the auxiliary tank and is filled therein due to a pressure difference between the auxiliary tank and the reservoir,
• a protect cover that is assembled onto the auxiliary tank to surround the plate-type heater;
• and
• a fastening device for fixing the plate-type heater and the protect cover to the auxiliary tank,
• wherein a flange of the heater is formed to be protruded along a surrounding of the plate-type heater, and the flange of the heater is bonded to a protect cover flange of the protect cover.
