Abstract
The utility model discloses a waterer with an emergency heat protector comprising a tank provided with a faucet and heating pipes, which is characterized in that: a temperature probe, a grounding probe, a low water level probe and a high water level probe are fixed on the tank, which are all connected with one end of a computer control board with pre-set control procedure Whose another end is respectively connected with a heating control relay and a watering electromagnetic valve. The utility model is reasonably structured and skillfully constructed. As electronic temperature control is provided with a high accuracy, power can be cut off when abnormal condition appears. As a result, internal electrical elements can be effectively protected. The utility model is worth popularizing.
Description
Technical field
The utility model relates to the drinking device technical field, specifically, relates to a kind of boiling water machine.
Background technology
At present, the limit protection device that the boiling water machine adopts is with the temperature control of the screw solid mechanical formula limit in boiling water machine liner upper back.When temperature in the water tank reached capacity the design temperature of temperature control, limit temperature control disconnected control circuit, cut off the boiled water machine source, played the overtemperature prote effect.Use the shortcoming of mechanical type limit temperature control to be: because mechanical type limit accuracy of temperature control is lower, can accurately not disconnect when temperature exceeding standard, security is relatively poor.
Summary of the invention
The purpose of this utility model is, provides a kind of and can effectively overcome above-mentioned defective, can disconnect the boiling water machine that has high temperature limit protection device of control circuit exactly when temperature exceeding standard.
For achieving the above object; the utility model adopts following technical scheme: a kind of boiling water machine that has high temperature limit protection device; mainly form by the inner bag that is provided with tap and heating tube; it is characterized in that: the end that the temperature probe that is fixed with on the inner bag, grounded probe, low-level probe and high-level probe and preestablish the control computer plate of control program is connected, the other end of control computer plate then respectively with the heating control relay with add water solenoid valve and link to each other.
Because adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model is rational in infrastructure, is skillfully constructed; because electronic temperature control has degree of precision, can when taking place, abnormal conditions in time cut off the boiled water machine source; protect the inner electric elements of boiling water machine effectively, have promotional value.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, a kind of boiling water machine that has high temperature limit protection device mainly is made up of the inner bag 1 that is provided with tap 2 and heating tube 8, and the bottom of inner bag 1 is connected to entering water electromagnetic valve 9.Wherein, the end that the temperature probe 4 that is fixed with on the inner bag 1, grounded probe 3, low-level probe 7 and high-level probe 6 and preestablish the control computer plate 5 of control program is connected, the other end of control computer plate 5 then respectively with heating control relay 11 with add water solenoid valve 10 and link to each other.Its control mode of brief description: when abnormal conditions take place, (close as water inlet; electrothermal tube continues heating; temperature is too high); temperature probe elicites temperature and is higher than 98 ℃, and then the control of computer plate disconnects control circuit, boiling water tester in power-down state; need treat that temperature descends; behind the restarting equipment, could recover normal condition, play protective effect.
