Abstract
A hydraulic pressure switch is provided, which is mainly used for an instantaneous electric water heater, and comprises a shell, a membrane, a connecting rod, an inching switch and a spring. The shell wherein is arranged with a pressure sensing chamber is arranged in the shell and connected with a waterway. The membrane is positioned in the pressure sensing chamber and connected with the connecting rod. The connecting rod contacts a rocking arm of the inching switch. Hydraulic pressure acts on the membrane to enable the inching switch to act by driving the connecting rod, thus realizing hydraulic or non-hydraulic state division. The electric water heater works after being connected with water and electric power and automatically shuts off power source in case of water supply failure to avoid continuous power supply due to residual water and save electric power.
Description
Affiliated technical field
The utility model relates to a kind of by the hydraulic pressure switch on the electric switch device, particularly water heater of hydraulic pressure control.
Background technology
Present instant electric water heater is the resistance heating power that utilizes water, is provided with electrode in water heater, and water flows through electrode and heating power is switched on when water is arranged automatically during work, and no power when anhydrous quits work.But, when work just finishes, owing on the electrode residual low amounts of water is arranged, if the user forgets power cutoff, can continue the energising heating this moment, dryouied fully until water, cause waste of energy, electrode also can easily cause oxidation, reduction of service life because of heating in air simultaneously.
Summary of the invention
The utility model purpose provides the electric switch of a kind of hydraulic pressure control, makes the water heater work of switch on when water flowing, the automatically cutting off power source afterwards of cutting off the water supply.
Scheme of the present utility model is: hydraulic pressure switch is made up of housing, diaphragm, connecting rod, sensitive switch, spring, offer the pressure-sensitive cabin in housing, be communicated with the water route, pressure-sensitive is provided with diaphragm in the cabin, diaphragm is connected with connecting rod, and connecting rod contacts on the rocking arm of sensitive switch.Utilize the pressure of water to act on diaphragm, promote connecting rod and make the sensitive switch action, realize having the differentiation of water or anhydrous state.
The utility model has the advantages that: utilize the pressure effect of water, realize having the differentiation of water or anhydrous state, make the water heater work of when water flowing, switching on, automatically cutting off power source after cutting off the water supply, the continuation energising of having avoided residual water to cause, saves energy, and the oxidation of minimizing electrode.
Description of drawings
The utility model is described in further detail with embodiment with reference to the accompanying drawings below.
Accompanying drawing is a structural representation of the present utility model.
1 housing among the figure, 2 pressure-sensitive cabins, 3 diaphragms, 4 connecting rods, 5 springs, 6 sensitive switches.
Embodiment
As shown in the figure, there is joint at the two ends on the housing (1), are used to be connected on heater inleting pipe's water route.Having offered pressure-sensitive cabin (2) on the housing, is a cavity that is connected with the water route, is provided with diaphragm (3) in this cavity, adopts rubber-like rubber to make, and diaphragm (3) is connected with connecting rod (4), and the rocking arm of the other end of connecting rod (4) and sensitive switch (6) contacts.
When in the pipeline water being arranged, because the pressure of water, diaphragm (3) pressurized is pushed up to the left side (being seen by direction as shown), backs down by the rocking arm of connecting rod (4) with sensitive switch (6), and circuit is connected; When use finished or be anhydrous, diaphragm (3) did not stress, and spring (5) pulling rocking arm resets, and sensitive switch (6) turn-offs, and cuts off circuit.
By the effect of hydraulic pressure to sensitive switch (6), realized having the differentiation of water or anhydrous state, make the water heater work of when water flowing, switching on, the back automatically cutting off power source of cutting off the water supply.
Claims (1)
- A kind of hydraulic pressure switch is made up of housing, diaphragm, connecting rod, sensitive switch, spring, it is characterized in that: offer the pressure-sensitive cabin in housing, be communicated with the water route, pressure-sensitive is provided with diaphragm in the cabin, and diaphragm is connected with connecting rod, and connecting rod contacts on the rocking arm of sensitive switch.
