Abstract

The utility model relates to a whistling alarm capable of protecting dry-heating and water shortage. When the water level in a saucepan is lower than the whistling spring (5) arranged on the disk surface of a water level disk (3), the vapor produced in the water level disk (3) enters from the air hole (1) arranged on a lower shield (1), discharges from an air duct (6) arranged on the water level disk (3), and then discharges from the air hole (1) arranged on a upper shield (2); and when the vapor passes through the clearance formed between the air duct (6) arranged on the water level disk (3) and whistling spring (5), the whistling spring (5) vibrates to give an whistling alarm, thereby reminding the shortage of the water in the saucepan.

Description

Anti-dry lack of water siren

Technical field:

The utility model relates to a kind of anti-dry warning device, particularly a kind of family expenses steamer boiler alarm.

Background technology:

Electric steaming cooker or electrothermal water boiling kettle all have the anti-dry function in its circuit is provided with, and the family expenses steamer is difficult to from circuit solve the anti-dry problem owing to be to heat on gas-cooker generally; Also have mentality of designing to cut off combustion gas during overtemperature above gas-cooker, in case breaking out of fire, and the steamer on this moment kitchen range is by dry combustion method.

Summary of the invention:

The utility model provides a kind of water level in steamer to drop to just to begin below the warning line alarm of blowing a whistle.

The utility model is achieved through the following technical solutions:

Use spacing water level dish, one or more ring springs are set on water level dish card.

The beneficial effects of the utility model are: be lower than the ring spring below the water level in the steamer drops to the water level card after, the steam that produces in the water level dish makes the ring spring shake the warning of blowing a whistle.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1, Fig. 2, Fig. 3 be respectively of the present utility modelly look up, mainly look, vertical view.

Fig. 4, Fig. 5, Fig. 6 be respectively the utility model remove go up the looking up of lower shield, mainly look, vertical view.

Fig. 7, Fig. 8, Fig. 9 be respectively the looking up of the utility model upper shield, mainly look, vertical view.

Lower shield is identical with upper shield.

Figure 10 is a three-dimensional view of the present utility model.

Figure 11 is a decomposition view of the present utility model.

Among the figure 1, lower shield, 2, upper shield, 3, the water level dish, 4, bolt, 5, the ring spring, 6, air drain, 7, bolt hole, 8, gas port, 9, bolt hole.

With reference to accompanying drawing:

When the water level in the steamer is lower than ring spring [5] on water level dish [3] card, the steam that produces in the water level dish [3] enters from the gas port [8] of lower shield [1], during the gap that forms by air drain [6] on the water level dish [3] and ring spring [5], ring spring [5] vibrations are produced ring, discharge from the gas port [8] of upper shield [2] again from the gas that air drain [6] is discharged.

The lower shield [1] and the upper shield [2] that have bolt hole [9] can adopt same structure, are connected the surface and the bottom surface of water level dish [3] by the bolt hole [7] on bolt [4] and the water level dish [3], in order to protection ring spring [5].

Claims

1, a kind of anti-dry siren that is used to remind water level deficiency in the steamer, it is characterized in that: use a spacing water level dish [3], air drain [6] is arranged on its card, cooperate with air drain [6] to be equipped with ring spring [5], water level dish [3] surface and underrun bolt [4] and bolt hole [7] are connected with lower shield [1] and the upper shield [2] that has bolt hole [9].
