Abstract
The invention relates to an automatic anti-dry-heating device. The automatic anti-dry-heating device comprises a water tank (1) and a water pump (2), wherein an outlet of the water tank (1) is communicated with an inlet I of the water pump (2); an outlet I of the water pump (2) is communicated with one opening of a three-way pipe (3); the other two openings of the three-way pipe (3) are communicated with a small water tank (6) and an inlet II of a heating body (5) respectively; a heating pipe (4) is mounted in the heating body (5) vertically; a float switch (7) is arranged in the small water tank (6); a reed switch (8) is mounted on the wall on one side, close to the float switch (7), of the small water tank (6); the vertical height of the reed switch (8) is lower than that of the upper end point of the heating pipe (4); the reed switch (8) is connected with one connecting opening of a main control plate (9); the other two connecting openings of the main control plate (9) are connected with a button plate (11) and the water pump (2). The automatic anti-dry-heating device provided by the invention eliminates an anti-dry-heating button, the float switch in the small water tank is utilized to be linked with water level in the heating body, and the conventional passive (manual) anti-dry-heating is changed into the initiative anti-dry-heating; thus, the heating can be started through a button, and the operation is simple.
Description
Technical field
The invention belongs to water dispenser apparatus field, particularly relate to a kind of automatic device for preventing burning dry.
Background technology
The instant heating type drinking machine product that 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 meeting water outlet, cause complicated operation.And in the process using, there is the phenomenon of lack of water because a variety of causes such as problem or maloperation of product causes calandria the inside, adding the dry combustion method of hankering causing calandria, affect quality and the safety of product.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of automatic device for preventing burning dry, to solve existing anti-parching device for drinking device complicated operation, the easy problem of makeing mistakes.
The technical solution adopted for the present invention to solve the technical problems is: a kind of automatic device for preventing burning dry is provided, comprise water tank and water pump, water tank outlet is communicated with pump entrance, described exit of pump is communicated with a mouth of three-way pipe, two other of three-way pipe mouthful is communicated with respectively the entrance of little water tank and calandria, a heating tube is vertically installed in calandria, in little water tank, be provided with switch, switch is pressed close on the little water tank wall of a side tongue tube is installed, 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 present invention has cancelled anti-dry button, by the water level interlock in switch and calandria in little water tank, former passive (craft) anti-dry is become to initiatively anti-dry; Make to heat a key and start, simple to operate.
Brief description of the drawings
Fig. 1 is structure chart of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment are only not used in and limit the scope of the invention for the present invention is described.In addition should be understood that those skilled in the art can make various changes or modifications the present invention after having read the content of the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
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.Have a three-way pipe 3 to connect calandria 5, the pipeline of little water tank 6 and water pump 2, is communicated with in U-shaped state little water tank 6 and calandria 5.One switch 7 is housed in little water tank 6 and has the supporting of tongue tube 8 phases, the height of the interior heating tube 4 of calandria 5 is higher than the height of switch 7.When water pump 2 is pumped into calandria 5, little water tank 6 the insides by three-way pipe 3 the water of 1 li, water tank, and height of water level and the calandria 5 water level inside height of 6 li, little water tank 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 in heating process always in water, can not cause dry combustion method, give master control borad 9 signals simultaneously, heating button is effective, otherwise height of water level does not reach a certain height, switch 7 and tongue tube 8 signals are always in off-state, represent that heating tube 4 has part exposed in air, be not to be all immersed in water, heating can cause product dry combustion method like this, now give master control borad 9 signals, heating stops.
Claims (4)
1. an automatic device for preventing burning dry, comprise water tank (1) and water pump (2), water tank (1) outlet is communicated with water pump (2) entrance, it is characterized in that: described water pump (2) outlet is communicated with a mouth of three-way pipe (3), two other of three-way pipe (3) mouthful is communicated with respectively the entrance of little water tank (6) and calandria (5), a heating tube (4) is vertically installed in calandria (5), in little water tank (6), be provided with switch (7), switch (7) is pressed close on little water tank (6) wall of a side tongue tube (8) is installed, 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) one interfaces, and other two interfaces of master control borad (9) connect keypad (11) and water pump (2).
