Rotary timer switch for water dispenser

Abstract

The invention discloses a rotary timing switch for a water dispenser. The rotary timing switch for the water dispenser comprises a water dispenser switch chamber, a rotary switch, a metal conducting rod, a torsion spring and a metal conducting base. The rotary switch comprises a rotary knob and a rotating shaft connected with the end of the rotary knob, the rotating shaft can be mounted in the water dispenser switch chamber in a rotatable mode, and the rotary knob is located outside the water dispenser switch chamber. One end of the metal conducting rod is fixed to the shaft face, away from the rotary knob, of the rotating shaft, and the other end of the metal conducting rod stretches in the direction opposite to the shaft face and is connected with a control end of a water dispenser temperature controller through wires. The torsion spring is mounted on the rotating shaft between the rotating knob and the metal conducting rod, and the two ends of the torsion spring are fixed to one inner side wall of the water dispenser switch chamber and the metal conducting rod respectively. The metal conducting base is provided with a U-shaped clip, mounted below the metal conducting rod and is connected with the other control end of the water dispenser temperature controller through wires. The rotary timing switch for the water dispenser can prevent repeated heating of the water dispenser, and prevent water from being boiled for a long time.

Description

technical field [0001] The invention relates to the field of timing switches, in particular to a rotary timing switch for a water dispenser. Background technique [0002] At present, the use of water dispensers is very common. Now take the warm water dispenser as an example for illustration. The working process is as follows: first press the heating switch, the heating circuit is connected, the electric heating tube is energized, and the drinking water in the hot tank starts to be heated; the water in the hot tank is heated When the temperature reaches the set 85°C, the contact of the thermostat is disconnected, the power supply of the heating circuit is cut off, and the electric heating tube stops heating; when the water temperature drops to 80-82°C, the contact of the thermostat is connected to the power circuit, and the electric heating tube heats up again; Keep the water temperature between 85 and 95°C over and over again. [0003] As can be seen from the above, there ...

AI Technical Summary

Problems solved by technology

[0004] 1. After the drinking water is repeatedly heated in the hot tank, it will form "thousand boiling water". This water contains harmful substances such as heavy metals and arsenic compounds. Long-term drinking will endanger your health;

[0005] 2. Taking the production of 1 liter of hot water as an example, a traditional household water dispenser with a power of 0.5 kilowatts consumes 1.8 degrees of electricity per day without shutting down the machine. Caused more than 90% of energy waste, which also makes the traditional water dispenser become the "king of power consumption" in household appliances
