Faucet capable of improving usage safety of heating heat exchanger

Abstract

Provided is a faucet capable of improving the usage safety of a heating heat exchanger. The faucet is provided with a valve structure which is capable of detecting whether or not a heat exchange tube of the heating heat exchanger is damaged and mixes hot water with cold water, and the faucet can synchronously control the water supply and water cut-off of a cold water inlet and a water outlet pipe, wherein the cold water inlet is located on the heat exchange tube of the heating heat exchanger, and the water outlet pipe is located on the faucet; when the faucet and the heating heat exchanger are used together, the faucet can simply, conveniently and visually detect whether or not the heat exchange tube of the heating heat exchanger is damaged and mixes hot water with cold water, and when the faucet detects whether or not hot water and cold water are mixed, at the same time, the function is achieved that hot water in a heating pipeline is prevented from being mixed with water in a water supply pipeline after the heat exchange tube of the heating heat exchanger is damaged, so that the damage of mixing water in the heating pipeline with water in the water supply pipeline due to the damaged heat exchange tube of the heating heat exchanger is effectively reduced and prevented. Therefore, it is guaranteed that the health and safety of a user of the heating heat exchanger are not violated, and the sanitation and safety of public drinking-water supply system are not violated.

Description

technical field [0001] The invention relates to a faucet capable of improving the safety of a heating heat exchanger. The heating heat exchanger referred to in the invention is also called a heating heat exchanger or a heating water heater. Background technique [0002] At present, due to quality problems and aging of the heating heat exchangers used by people, the heat exchange tubes in the heating heat exchangers are prone to damage, which will cause the hot water in the heating pipeline to flow into the tap water pipes, polluting the tap water, Directly jeopardize the health and safety of the user of the heating heat exchanger, and if the tap water used by the user comes from the public drinking water supply system, it will directly endanger the health and safety of the public drinking water supply system, and the harm it causes will be even greater. Big! The heat exchange tube of the heating heat exchanger is damaged, which will also cause the heat loss of the heating s...

[0002] At present, due to quality problems and aging of the heating heat exchangers used by people, the heat exchange tubes in the heating heat exchangers are prone to damage, which will cause the hot water in the heating pipeline to flow into the tap water pipes, polluting the tap water, Directly jeopardize the health and safety of the user of the heating heat exchanger, and if the tap water used by the user comes from the public drinking water supply system, it will directly endanger the health and safety of the public drinking water supply system, and the harm it causes will be even greater. Big! The heat exchange tube of the heating heat exchanger is damaged, which will also cause the heat loss of the heating system, or the tap water will enter the heating pipe, causing the heating pipe to not be hot.

[0003] For the disadvantages of the above-mentioned heating heat exchanger, the patent No. ZL201420164346.0 provides a solution, but claim 5 of the patent, that is, the faucet structure described in the fourth embodiment of the first embodiment of the patent specification, There will be some problems in actual use: the valve core of the faucet has many holes in the static valve plate. To ensure that the faucet realizes the flow required by the actual function, the diameter of the static valve plate and the moving valve plate of the valve core cannot be too small. , and when the valve core is closed, a corresponding hole on the static valve plate of the faucet, which is actually a cold water inlet hole, is connected to a groove on the moving valve plate, so that the excessive water pressure area and the moving valve plate are formed. The position of the groove is close to the edge of the movable valve plate, which reduces the sealing performance of the valve plate, which increases the difficulty of the sealing effect of the valve core. To make the sealing performance of the faucet meet the national standard, the movable valve plate must be enlarged. In this way, even if the sealing performance stipulated by the national standard is achieved, the opening and closing of the valve core will become very laborious, which will affect the operation performance of the faucet and the service life of the valve core, and will affect the faucet. The normal use and promotion of this faucet has caused troubles, because consumers find it difficult to accept the faucet's switch feel, which is far heavier than conventional faucets.

[0004] Patent No. ZL201420164346.0 and Patent No. ZL201320094787.3 describe the implementation of the faucet using a flat-rotating spool, in which the flow channel for detecting the string of water in the faucet is a normally open flow channel, which makes the faucet Unable to achieve complete cold water or complete hot water, affecting the use effect
