Description
Technical field
The utility model belongs to water dispenser apparatus field, particularly relates to a kind of automatic device for preventing burning dry.
Background technology
Instant heating type drinking machine product used in the market, generally can increase an anti-dry keypress function in use procedure, could heat after making faucet have water to go out.Due to the many buttons of needs and faucet can water outlet, cause complicated operation.And in the process used, because a variety of causes such as the problem of product or maloperation cause the phenomenon having lack of water inside calandria, adding the dry combustion method hankering causing calandria, affecting quality and the safety of product.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of automatic device for preventing burning dry, with the problem solving existing anti-parching device for drinking device complicated operation, easily make mistakes.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of automatic device for preventing burning dry, comprise water tank and water pump, tank outlet is communicated with pump entrance, described exit of pump is communicated with a mouth of three-way pipe, two other mouthful of three-way pipe is communicated with the entrance of little water tank and calandria respectively, a heating tube is vertically installed in calandria, switch is provided with in little water tank, the little water tank wall that side pressed close to by switch is provided with tongue tube, and the vertical height of tongue tube is lower than the vertical height of heating tube upper extreme point; Tongue tube is connected with master control borad one interface, and other two interfaces of master control borad connect keypad and water pump.
Described calandria outlet is communicated with water outlet of drinking machine.
Described switch is magnetic switch.
Described keypad is positioned on the housing on water outlet of drinking machine top.
Beneficial effect
The utility model eliminates anti-dry button, is linked by the switch in little water tank and the water level in calandria, former passive (craft) anti-dry is become initiatively anti-dry; Heating one key is started, simple to operate.
Accompanying drawing explanation
Fig. 1 is the utility model structure chart.
Detailed description of the invention
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
Embodiment 1
As shown in Figure 1, a kind of anti-dry burning device automatically, comprises master control borad 9, water tank 1, calandria 5, water pump 2, switch 7, keypad 11 etc.There is a three-way pipe 3 to connect calandria 5, the pipeline of little water tank 6 and water pump 2, little water tank 6 is communicated with calandria 5 and is in U-shaped state.Little water tank 6 is built with a switch 7 and have the supporting of tongue tube 8 phase, and in calandria 5, the height of heating tube 4 is higher than the height of switch 7.When water pump 2 is pumped into the water of 1 li, water tank inside calandria 5, little water tank 6 by three-way pipe 3, and the height of water level of 6 li, little water tank and calandria 5 water level inside height will be consistent, along with constantly adding water, water level in little water tank 6 raises, switch 7 also increases, make the signal communication of itself and tongue tube 8, at this moment height of water level has exceeded the height of heating tube 4, so product is in water in heating process always, dry combustion method can not be caused, give master control borad 9 signal simultaneously, heating button is effective, otherwise height of water level does not reach a certain height, switch 7 and tongue tube 8 signal are in off-state always, representing heating tube 4 has partial denudation in atmosphere, be not all be immersed in water, such heating can cause product dry combustion method, now give master control borad 9 signal, heating stops.
Claims (4)
1. an automatic device for preventing burning dry, comprise water tank (1) and water pump (2), water tank (1) outlet water pump (2) entrance, it is characterized in that: a mouth of described water pump (2) outlet three-way pipe (3), two other mouth of three-way pipe (3) is communicated with the entrance of little water tank (6) and calandria (5) respectively, a heating tube (4) is vertically installed in calandria (5), switch (7) is provided with in little water tank (6), little water tank (6) wall that side pressed close to by switch (7) is provided with tongue tube (8), and the vertical height of tongue tube (8) is lower than the vertical height of heating tube (4) upper extreme point, tongue tube (8) is connected with master control borad (9) interface, and other two interfaces of master control borad (9) connect keypad (11) and water pump (2).
2. a kind of automatic device for preventing burning dry according to claim 1, is characterized in that: described calandria (5) outlet is communicated with water outlet of drinking machine.
