Description

Technical Field

[0001] The present invention relates to the technical field of bathroom equipment, and in particular to a hot water and cold water mixing device and a bathroom water temperature control system having the same. Background Art

[0002] The valve is a control component in the pipeline fluid delivery system, which is used to change the passage section and the flow direction of the medium. It has the functions of diversion, cut-off, throttling, non-return, diversion or overflow pressure relief. The hot water and cold water mixing device is a device used in bathroom facilities to control the direction, flow rate, pressure, etc. of the water flow. The temperature regulating valve can adjust the temperature of the hot water and is usually installed in the water heater to adjust the temperature of the hot water.

[0003] In the prior art, a general hot water and cold water mixing device is installed on the water pipe of the water heater. When bathing, the user needs to adjust the valve first to mix the cold water and hot water to a suitable temperature before bathing. However, the hot water valve and the cold water valve of the existing bathroom water temperature control system are both separately set up as a component, and then the hot water valve and the cold water valve are connected to the mixing chamber respectively through the connecting pipe. On the one hand, the separate setting of the hot water valve and the cold water valve will lead to a relatively scattered structure, a large volume, and occupy more space. On the other hand, since a part of hot water or cold water will be retained in a long connecting pipe, when the user feels that the water temperature is high and wants to lower the water temperature, the hot water valve and the cold water valve will respectively control less hot water and more cold water to enter the mixing chamber, thereby lowering the mixed water temperature in the mixing chamber. However, more hot water will remain in the connecting pipe, which will lead to more hot water flowing into the mixing chamber for a period of time, that is, the water temperature is still high for a period of time. The user needs to wait for a period of time before feeling the required water temperature, resulting in a lag in water temperature regulation, and cannot be quickly adjusted to the bathing water temperature required by the user in time. The user experience is poor and cannot meet user needs. Summary of the invention
