Description

Technical Field

[0001] This utility model relates to the field of constant temperature water dispensing technology, specifically a constant temperature foot pedal water dispensing device. Background Technology

[0002] The constant temperature water outlet device is a valve used in household hot water systems, restaurants, hospitals, and schools. It maintains a constant water temperature, ensuring high safety. According to national food safety regulations, dishes in the cold dish preparation area of ​​the kitchen are consumed directly without heating, thus requiring higher hygiene standards. Since staff entering the cold dish preparation area handle various foods, this device was developed to prevent cross-contamination and to efficiently, conveniently, and hygienically clean the dishes. It also aims to encourage innovation and small-scale improvements among the company's logistics staff, further enhancing the company's food safety standards.

[0003] Most existing constant temperature water dispensing devices require manual operation of the water valve. During cooking, the chef needs to stop what they are doing to control the water flow, which reduces cooking efficiency to some extent. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] In view of the problems existing in the above and / or existing thermostatic foot pedal water dispensing devices, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a thermostatic foot-operated water dispensing device. During use, when the first fixed frame is stepped on, it rotates along the first rotating axis, which, through cooperation with the first connecting rod, drives the ball valve to open. Cold water flows from the third cold water pipe through the first three-way pipe into the second cold water pipe, and then from the second three-way pipe through the hose into the outlet pipe for discharge. When the second fixed frame is stepped on, it rotates along the first rotating axis, which, through cooperation with the first connecting rod on the other side, drives the other ball valve to open. Hot water flows from the second hot water pipe through the thermostatic mixing valve into the outlet pipe for discharge. When the first and second fixed frames are stepped on simultaneously, cold and hot water simultaneously enter the thermostatic mixing valve and then exit through the outlet pipe. The mixing ratio of cold and hot water is adjusted by the thermostatic mixing valve to regulate the water temperature. The rubber foot pedal increases friction and provides a certain degree of anti-slip effect. This solves the problem that most existing thermostatic water dispensing devices are operated by hand, requiring the chef to stop cooking to operate the water valve to control the water flow, which reduces cooking efficiency to some extent.
