Boiling water or steam generating device capable of rapidly heating by utilizing heating pipeline

Abstract

The invention discloses a boiling water or steam generating device capable of rapidly heating by utilizing a heating pipeline. The boiling water or steam generating device comprises a water pump, a communication container, a heating pipeline, a first relay, a second relay, a boiling water starting switch, a boiling water heating switch, a steam starting switch, a steam heating switch and a selection control circuit; the boiling water or steam generating device capable of rapidly heating by utilizing the heating pipeline is characterized in that the boiling water starting switch and the boilingwater heating switch are installed in a higher position in the communication container, and a first group of control switch is formed; the steam starting switch and the steam heating switch are installed in a lower position in the communication container, and a second group of control switch is formed; the steam heating switch is located in the vicinity of the half height of the heating pipeline;the selection control circuit selects one of the first group of control switch or the second group of control switch to work; and further comprises an air control part which is arranged in the communication container, the air control part occupies most of the volume of the communication container, and a flow channel of a water inlet and a water outlet is formed by the gap between the air controlpart and the communication container; and the water level of the communication container can be quickly adjusted when the selection of the device have conversion between the boiling water and the steam.

Description

technical field [0001] The invention belongs to a device for quickly heating water in places such as homes, offices, industrial mines, troops, schools, etc., and is applied to water dispensers. A device for instantly obtaining boiling water or water vapor. It has a variety of functions to choose from, and can choose to generate a large amount or a small amount of boiling water and water vapor to achieve boiling water, brewing or decocting beverages, such as tea, coffee and decoction. etc., the active ingredients can be extracted from drinks or medicine packs. Background technique [0002] Existing water dispensers or tea machines have widely entered daily life. Among these appliances, some are heated by heating plates, some are heated by immersion electric heating tubes, and some are heated by induction cookers. It takes a long time to boil the water, and the user needs to wait for a long time. It is impossible to obtain hot water or boiling water that meets the temperatur...

Problems solved by technology

[0007] But, among the two schemes of the above-mentioned invention, one scheme adopts two pipelines and electromagnetic valve and check valve to realize, and its structure is comparatively complicated, and when changing from boiling water to steam generation state, must heat the upper part of the pipeline A large amount of excess water is consumed, so that the subsequent steam does not contain a large amount of water; another solution is to use another water pump to pump the excess water in the connector and the heating pipe to the choice of converting boiling water into steam. The structure of the return tank is still relatively complicated, and it needs to go through the process of pumping water, which increases the waiting time for people to get steam, and there is a time delay

[0008] In addition, since the water level switch has a certain volume, its lead wire must be drawn out, and the connecting container is also equipped with several water level switches due to the needs of different water level control, which constitutes a restriction on the design of the connecting container, so that the connecting container must have A certain volume and shape, and its internal structure has steps, which will inevitably have a greater impact on the adjustment of water volume and water level
