2. contact switch condensate tank of dehumidifier, this class formation is installed the contact switch of a sensitivity in the bottom of water level detecting pipe, and when water level was low, float dropped to the bottom of water level detecting pipe, and trigger switch disconnects heater circuit, thereby has guaranteed security.Because this class formation directly places the part of circuit in the water level detecting pipe, places water for a long time, so trigger switch needs very high watertightness, guarantee that water can not influence the work of circuit, increased cost on the one hand, member is aging easily on the other hand, and serviceable life is short.
Summary of the invention
Goal of the invention of the present utility model is to overcome deficiency of the prior art, and providing a kind of can accurately monitor, in stable condition, the condensate tank of dehumidifier of long service life.
Inventive concept of the present utility model is to seek a kind of stable pilot signal source, is used for substituting the structure of available technology adopting infrared detection or mechanical contact-type, through decision after the contrast of multiple signal source being selected for use the signal source of magnetic field as monitoring.Because it is in stable condition that magnetic field possesses, the penetrability height, high temperature resistant and intensity is specially adapted to the water level detecting of household electrical appliance with the characteristics that distance is inversely proportional to, as electric kettle, electric heater etc.
The utility model mainly is to be achieved through the following technical solutions its goal of the invention:
The utility model is as a kind of condensate tank of dehumidifier that is applied in the household electrical appliance, its structure includes water level detecting pipe, float and induction installation, water level detecting pipe bottom is communicated with container, upper opening, form the communicating pipe structure with container, make that the water level in the container is consistent with the height of water level in the water level detecting pipe, float is positioned at the water level detecting pipe, induction installation is located at the outside, water level detecting pipe bottom, described float comprises shell and magnetic, magnetic is sealed in the shell, and induction installation is a magnetic-inductive device.Principle of work of the present utility model mainly is to detect the magnetic field intensity of magnetic by induction installation; reduction along with water level; the distance of magnetic distance sensing device is more and more nearer; the magnetic field intensity that induction installation is sensed is along with reinforcement; when magnetic field intensity reaches certain intensity, promptly decline of water table is to safe water bit line following time, and induction installation promptly produces action; disconnect heater circuit, thereby play the purpose of protection electrical equipment.Because magnetic field is more stable, generally speaking not with external influence, so testing result of the present utility model is very accurate, and serviceable life is very long, and result of use also can keep stable for a long time.
Of the present utility model simple in structure, the cost of member is low, and general magnetic adopts permanent magnet to get final product, induction installation can be used the steel spring pipe, the steel spring pipe is to be in closure state generally speaking, just can disconnect when sensing than high-intensity magnetic field, so can come the conducting and the disconnection of control circuit with it.The steel spring pipe is connected in water level detecting pipe lower end by fixed mount, and fixed mount can be used to regulate the height of induction installation, thereby reaches the purpose of regulating the water level critical line according to concrete electrical equipment.Be the position of control float, in the water level detecting pipe, the downside of induction installation is provided with limited block, be used to limit float and continue to sink to causing weakening of magnetic field with water level.
It when the utility model is applied to the anti-dry burning device of electric kettle a kind of electric kettle condensate tank of dehumidifier, include the water level detecting pipe, float and induction installation, the water level detecting pipe is communicated with hot-water bottle inner bag bottom apopore by conduit, the cross-sectional area of described conduit is less than the cross-sectional area of float, the logical top of water level detecting pipe connects the hot-water bottle rising pipe and connects, form the communicating pipe structure with the hot-water bottle inner bag, float is positioned at the water level detecting pipe, and the cross-sectional area of the big rising pipe of cross-sectional area of described float, induction installation is located at water level detecting pipe lower end, be electrically connected with heater circuit, described float comprises shell and magnetic, magnetic is sealed in the shell, and induction installation is the steel spring pipe.The utility model has been simplified the structure of electric kettle with the discharging device of condensate tank of dehumidifier and the electric kettle formula structure that is combined into one, and has reduced production cost.
The utility model has following outstanding substantive distinguishing features and obvious improvement with respect to prior art:
1. adopt magnetic field as signal source, signal stabilization detects accurately;
2. long service life, and signal condition is stable;
3. simple in structure, can be combined as a whole with structures such as rising pipes;
4. install simple and easyly, production cost is low.
