Abstract
The invention discloses a washing machine water heater control system capable of avoiding potential safety hazards. The washing machine water heater control system comprises a heating pipe, an exhaust valve assembly and a washing machine outer drum. The heating pipe is arranged on the washing machine outer drum, an air chamber in the exhaust valve assembly is provided with three air nozzles, one of the air nozzles is connected with a water level sensor, the other two air nozzles are connected with water level switches, and the water level switches are arranged on the rear end face of the washing machine outer drum and used for controlling the washing machine outer drum to be opened at the highest water point and closed at the lowest water level. The washing machine water heater control system overcomes defects of the prior art, the design structure is reasonable, the new air chamber is added to be connected with the water level switches, and the water heating pipe is opened and closed by measuring the water level, so that the potential safety hazards caused by failure of software are avoided.
Description
Technical field
The present invention relates to washing machine heater control technology field, be specifically related to a kind of washing machine water Heater Control System avoiding potential safety hazard.
Background technology
At present, washing machine has become the indispensable electrical equipment in family, novel washing machine is all with water heating function, and the heating of water is energized by heating tube, send high temperature and carry out heating water, because the urceolus of washing machine is plastic products, general air chamber is merely able to the data transmitted by level sensor, by the work of software control water heating tube, but utilize software also can there is certain potential safety hazard.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of washing machine water Heater Control System avoiding potential safety hazard, overcome the deficiencies in the prior art, project organization is reasonable, by increasing new air chamber and the connection of water level switch, by measuring the height of water level, carry out switch water heating tube, thus avoid the inefficacy of software, the potential safety hazard brought.
Technical problem to be solved by this invention can be come to be realize by the following technical programs:
A kind of washing machine water Heater Control System avoiding potential safety hazard, comprise heating tube, draining valve assembly and washing machine urceolus, heating tube is arranged on washing machine urceolus, air chamber on described draining valve assembly has three valves, one of them valve connects level sensor, two other connects water level switch, and water level switch is arranged on washing machine urceolus rear end face and opens at peak for the water level controlling to arrange in washing machine urceolus, and minimum point is closed.
Air chamber on described draining valve assembly is connected with glue by buckle, is fixed on washing machine urceolus, and the level sensor that air chamber connects is for detecting the waterlevel data of washing machine urceolus and being sent to control mainboard.
Compared with prior art, beneficial effect of the present invention is:
The present invention when heating tube works, can be measured the height of water level, and makes effective action by water level switch, avoid when software control is malfunctioning, and the safe operation of protection washing machine, structure is simple, safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is air chamber structure schematic diagram of the present invention.
Detailed description of the invention
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
A kind of washing machine water Heater Control System avoiding potential safety hazard, comprise heating tube 1, draining valve assembly 2 and washing machine urceolus 3, heating tube 1 is arranged on washing machine urceolus 3, air chamber 4 on described draining valve assembly 2 has three valves 401, one of them valve 1 connects level sensor 5, two other connects water level switch 6, 7, water level switch 6, 7 are arranged on washing machine urceolus 3 rear end face and open at peak for the water level controlling to arrange in washing machine urceolus 3, minimum point is closed, air chamber 4 on described draining valve assembly is connected with glue by buckle, be fixed on washing machine urceolus 3, the level sensor 5 that air chamber 4 connects is for detecting the waterlevel data of washing machine urceolus and being sent to control mainboard, the valve 1 of air chamber is connected by rubber tube with level sensor 5, the valve 2 402 of air chamber is connected by rubber tube with water level switch 1, the valve 3 403 of air chamber is connected by rubber tube with water level switch 27, heating tube 1 electrical wire wiring place is connected with water level switch 1, another electrical wire wiring place of heating tube is connected with water level switch 27, when height of water level arrives connection water level, water level switch 6, 7 open, water heating tube 1 can work, when height of water level is lower than disconnection water level, water level switch 6, 7 close, water heating tube 1 can not work, avoid when software control is malfunctioning, the safe operation of protection washing machine, structure is simple, safe and reliable.
It should be noted that, in this article, such as term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the process of a series of key element, method, article or equipment and not only comprise those key elements, but also comprise other key elements clearly do not listed, or also comprise by the intrinsic key element of this process, method, article or equipment.When not more restrictions, the key element limited by statement " comprising ... ", and be not precluded within process, method, article or the equipment comprising described key element and also there is other identical element.
Above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
