Abstract

The utility model relates to an electrical kettle, in particular to a kettle with a temperature and water level detection two-in-one system. The kettle comprises a kettle body (1), a base (2), a connecting wire, a temperature detection resistor (3) and a water level switch head (4), wherein the temperature detection resistor (3) is connected with the water level switch head (4) in parallel, and the water level switch head (4) and the temperature detection resistor (3) construct a component to be arranged on the upper side of the inner wall of the kettle body. The kettle adopting the technical scheme has the advantages that the water volume is accurately controlled, and water is avoided from overflowing.

Description

A kind of kettle with temperature and the two-in-one system of water level detecting

Technical field

The utility model relates to a kind of insulating pot, particularly a kind of kettle with temperature and the two-in-one system of water level detecting.

Background technology

In the prior art, measure temperature during insulating pot work and control respectively with the measurement water level, there is certain problem in prior art, when certain water yield is arranged in the kettle, sometimes can cause water to diffuse out outside the kettle because of carelessness.

The utility model content

For addressing the above problem, the utility model provides a kind of temperature and water level to control simultaneously, the kettle of accurately controlling the water yield, avoiding water to overflow.

To achieve these goals; The band temperature of the utility model and the kettle of the two-in-one system of water level detecting; Comprise kettle body, base; Connecting line, temperature detection resistance and water level switch head, said temperature detection resistance and the parallel connection of water level switch head, said water level switch head and temperature detection resistance constitute an assembly and place kettle body inwall upside.

Said water level switch head is connected with virtual switch, this virtual switch one end ground connection.Said virtual switch is not the switch of necessary being, and virtual come out is exactly water level in fact for its principle is described, when water level touched the water level switch head, the original current potential of water level switch head is short circuit over the ground, had equated with the current potential on ground.

Said temperature detection resistance and the sub-A of water level switch head end and B receive the single-chip microcomputer that places base through lead-out wire respectively, and said single-chip microcomputer connects AC power.

The beneficial effect of the utility model is: the band temperature of the utility model and the kettle of the two-in-one system of water level detecting, because temperature detection resistance and the parallel connection of water level switch head, said water level switch head places kettle body inwall upside; Said temperature detection resistance and water level switch head lead-out wire terminal A and B two ends apply voltage, and when water level was added to the water level switch head, the A point voltage was connected over the ground; A point current potential changes, and single-chip microcomputer receives information, through software program instructions; Notice make-up water pump motor quits work, and removes to control amount of water thereby reach with water level, regardless of water level in the kettle; As long as meet the requirements of waterline when adding water, water pump will quit work.

Fig. 2 is a circuit working theory structure sketch map.

Fig. 3 is the operation principle sketch map of kettle.

The specific embodiment

Below in conjunction with Figure of description the utility model is described further.

Like Fig. 1, Fig. 2 and shown in Figure 3, the band temperature of the utility model and the kettle of the two-in-one system of water level detecting comprise kettle body 1, base 2, the two-in-one survey part that connecting line, temperature detection resistance 3 and water level switch head 4 are combined into, and place kettle body inwall upside; Saidly be combined into two-in-one survey part terminal A and B receives the single-chip microcomputer 6 that places base through lead-out wire respectively, said single-chip microcomputer connects AC power 7, and pump motor 8 is controlled in the heating of said single-chip microcomputer one side output water receiving kettle simultaneously.

Said water level switch head 4 is connected with virtual switch 5, this virtual switch one end ground connection.

During work, after energized, single-chip microcomputer notice water pump begins water is injected in the kettle; And can notify heating simultaneously, two-in-one survey part is started working simultaneously, on one side detected temperatures one side sensed water level; When water level reaches assigned address; Single-chip microcomputer notice water pump quits work, and when temperature reached the temperature of appointment, single-chip microcomputer notice alternating current output cut off power supply.

Above embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that the common engineers and technicians in this area make the technical scheme of the utility model all should fall in the protection domain that claims of the utility model confirm.
