Abstract
The utility model discloses a combination control valve used for an instantaneous electric water heater and the instantaneous electric water heater provided with the combination control valve, belonging to the technical field of household appliances. The combination control valve is composed of a valve body with an inlet pipe and an outlet pipe as well as a valve plug, and is characterized in that one side of the valve body is provided with a pressure chamber communicated with a current-limiting pipe. The pressure chamber is provided with a rubber valve plate fastened and tightly connected with the valve body by a valve cover. The exterior face of the rubber valve plate is connected with a handspike assembly and passes through the valve cover to contact with a piston outside the valve cover. A switch bracket is installed on the valve cover. The combination control valve has the advantages of simple structure, small and compact volume, and convenient installation. Multi-position adjustment can be realized to satisfy the choice of different temperatures and different heating powers. Both security and practicability are obviously improved. The combination control valve is applied to various instantaneous electric water heaters.
Description
Technical field
The utility model discloses a kind of instant electric water heater compound control valve that uses and the instant electric water heater that compound control valve is housed, belong to tame electro-technical field.
Background technology
At present, instant electric water heater's characteristics of energy saving displays day by day, and the trend that replaces the heat storing type electric water heater is arranged.Before the utility model was made, traditional instant electric water heater need be provided with the water transfer valve and adjust the water yield, adjusts water temperature indirectly; Also need to be provided with water flow switch, to the startup of heater with close and control.So the numerous and diverse total member of its structure is many, not only be difficult to reduce cost, pipe joint is many, also increases some breakthroughs, and the volume of water heater also is difficult to dwindle.
Summary of the invention
The utility model is at the deficiency of prior art, and the volume that provides a kind of instant electric water heater to use is little, the compound control valve of compact conformation and instant electric water heater that compound control valve is housed.
Technical characterictic of the present utility model is the side at the water transfer valve, and the transmission mechanism of water flow switch has been installed, and water transfer valve and water flow switch are combined into one, and has simplified coupling assembling.
Control principle of the present utility model is: utilize the discharge pressure in the valve body to promote rubber valve plate, drive push rod, piston carry out Synchronization Control to microswitch.
Below introduce structure of the present utility model in detail, the compound control valve that a kind of instant electric water heater uses, constitute by the valve body of bringing water pipe and outlet pipe into, spool, it is characterized in that valve body one side has the pressure chamber that is connected with current limiting tube, rubber valve plate is housed in the pressure chamber to be fastened and connected itself and valve body by valve gap, the outside connection push rod combination of rubber valve plate is passed valve gap and is contacted with the piston in the valve gap outside, and switch bracket is housed on the valve gap, between switch bracket and the piston back-moving spring is housed.
A kind of instant electric water heater with compound control valve, by the Heating Cup that breaker, thermosistor, heater are housed, water transfer valve, power regulating switch and the water-in and water-out mouth of pipe constitute, valve body one side that it is characterized in that the water transfer valve has the pressure chamber that is connected with current limiting tube, rubber valve plate is housed in the pressure chamber to be fastened and connected itself and valve body by valve gap, the outside connection push rod combination of rubber valve plate is passed valve gap and is contacted with the piston in the valve gap outside, switch bracket is housed on the valve gap, between switch bracket and the piston back-moving spring is housed.
During the utility model work, open valve, cold water enters valve body by water inlet pipe mouth, entering current limiting tube through spool is flowed out by outlet pipe, the pressure chamber that is communicated with current limiting tube is experienced the pressure of water outlet, the rubber valve plate pressurized drives the push rod combination to the valve body movement outside, and the microswitch that the piston in the promotion valve gap outside will be installed on the switch bracket is opened, and connects heater power source.Valve-off, cold water no longer enters valve body by water inlet pipe mouth, and the impression of the pressure chamber that is communicated with current limiting tube is less than the pressure of water outlet, the rubber valve plate lateral movement in valve body that resets, the microswitch that the piston in the valve gap outside will be installed on the switch bracket cuts out, and cuts off heater power source.
The utility model has the advantages that simple in structure, compact volume is little, be convenient to install; Can realize that many gears regulate the selection of satisfying different temperatures, different heating power; The security practicality all obviously improves.Be applicable to various instant electric water heaters.
The utility model is described in further detail below in conjunction with accompanying drawing.
