Water dispenser overheat protection device capable of achieving automatic power off based on air thermal expansion

Abstract

The invention discloses a water dispenser overheat protection device capable of achieving automatic power off based on air thermal expansion. The device structurally comprises a water bucket receivingseat, a water dispenser body, a power connection indicator board, water taps, a water joint, a water tank and a remaining water receiving seat. The water dispenser body is a cuboid, the water bucketreceiving seat is embedded in the middle of the top end in a fastening mode, the power connection indicator board is embedded in the front top corner in a locking mode and electrically connected withthe water dispenser body, and the water tank is integrally arranged in the middle of the front end. The water joint is embedded in the top end of the water tank in a locking mode and locked with the water dispenser body. Two water taps are provided, both embedded in the water dispenser body in a fastening mode and located on the left side and the right side of the top end of the water tank, and can be connected with a manual electric heating mechanism through a thermal expansion mechanism. When the device is used, the device automatic power off in case of overheating can be achieved through the thermal expansion principle, electronic detection is not required, and the device is more convenient to repair and maintain. A heat insulation and expansion detecting mechanism adopted can better avoid the environmental impact on the device detection and make the device more convenient to use.

Description

technical field [0001] The invention relates to an overheat protection device for water dispensers that automatically cuts off power based on thermal expansion of air, and belongs to the field of overheat protection devices for water dispensers. Background technique [0002] In order to facilitate people's drinking, existing water dispensers are often provided with hot water and cold water outlets. Because hot water is needed, the inside of the water dispenser is often provided with a hot water storage tank for storing water for heating, so that hot water can be used for heating. After heating in advance, the user can directly use it. However, after heating the hot water for drinking water, it is easy to cause overheating damage to the equipment because the heater is still running continuously, and the heated water is likely to change the water quality after repeated heating, resulting in drinking water. unhealthy.

[0002] In order to facilitate people's drinking, existing water dispensers are often provided with hot water and cold water outlets. Because hot water is needed, the inside of the water dispenser is often provided with a hot water storage tank for storing water for heating, so as to facilitate the heating of hot water. After heating in advance, the user can directly use it. However, after heating the hot water for drinking water, the heater is still running continuously, resulting in overheating damage to the equipment, and the heated water is likely to change the water quality after repeated heating, resulting in drinking water. unhealthy

[0003] Traditional overheating protection devices use electronic thermometers to detect the temperature and then control the controller to cut off the power. However, because electronic thermometers are easily affected by the environment and difficult to repair after damage, it is inconvenient to assemble and use the water dispenser.
