Indoor heater glass panel heat shock resistance testing device

Abstract

The invention provides an indoor heater glass panel heat shock resistance testing device. The indoor heater glass panel heat shock resistance testing device is characterized by comprising a water supply device, a power supply device, a prototype temperature measuring device and a control cabinet which are separately connected with the water supply device, the power supply device and the prototypetemperature measuring device; the prototype temperature measuring device adopts a temperature measuring thermocouple, and the temperature measuring thermocouple is connected with the control cabinet;the power supply device comprises a prototype power supply socket and a thermocouple socket which are installed on a base and connected with the control cabinet; the water supply device comprises a water tank, a water pump, a water flow sensor and a water pipe which are connected with one another, a temperature controller and a temperature sensor are arranged in the water tank, the water tank is also installed on a base, and the water pump, the water flow sensor, the temperature controller and the temperature sensor are all connected with the control cabinet. The indoor heater glass panel heatshock resistance testing device has the advantages that a 5mm pipe can be fixed towards the central position of a glass panel of a heater and can be kept in place, automatic control is adopted, the water temperature and the flow rate of testing water can be accurately controlled, and a test can be automatically finished when the capacity of the testing water reaches 1L.

Description

technical field [0001] The invention relates to the technical field of detection of indoor heating devices, in particular to a thermal shock resistance test device for glass panels of indoor heaters. Background technique [0002] Article 22.107 of the safety testing standard for indoor heater products GB4706.23-2007 stipulates: "The accessible glass panel that is in direct contact with the heating element should be able to withstand thermal shock." [0003] According to the provisions of the safety testing standard GB4706.23-2007 for indoor heater products: firstly, the heater works at 1.15 times the rated power until it reaches a steady state. Then, pour 1L of water at a temperature of 15°C at a rate of 10mL / s directly to the center of the panel through a pipe with a diameter of 5mm. After the test, the glass panel should not be damaged such as cracking. [0004] At present, the thermal shock resistance test of the glass panel of the indoor heater is usually carried out m...
