Embodiment Construction
[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0026] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

The invention relates to a liquid level monitoring structure, a drainage device and heat exchange equipment. The liquid level monitoring structure is used for monitoring the liquid level height of liquid to be measured, the liquid level monitoring structure comprises a variable capacitance assembly and a lifting assembly, one end of the lifting assembly extends into the variable capacitance assembly, the other end of the lifting assembly is immersed into the liquid to be measured, wherein the lifting assembly can lift according to the liquid level of the liquid to be measured to change the capacitance value of the variable capacitance assembly, a liquid level detection device can directly convert the liquid level lifting of condensed water into the capacitance value of the variable capacitance assembly through the lifting assembly, so that the liquid level detection device is not affected by the difference of the internal resistance of the condensed liquid, and the device has higher monitoring precision and accuracy.
Description
technical field [0001] The invention relates to the technical field of heat exchange, in particular to a liquid level monitoring structure, a drainage device and heat exchange equipment. Background technique [0002] With the development of economy and technology and the improvement of living standards, people pay more and more attention to environmental protection, followed by people's requirements for energy efficiency of household electrical appliances are also getting higher and higher. [0003] A condensing gas water heater is a device that uses gas combustion to heat, thereby outputting hot water for people to use. Since the condensing water heater can use the efficient condensation preheat recovery device to absorb the present heat in the high-temperature flue gas discharged from the water heater and the latent heat released by the condensation of water vapor, the thermal efficiency of the condensing gas water heater is much higher It is more and more widely used in ...
