Abstract
The utility model discloses a water level detector for household solar water heater, which comprises a power supply, a water level detection device, a control device and an alarm device. A signal output end of the water level detection device is connected with a signal input end of the control device. A signal output end of the control device is connected with a signal input end of the alarm device, and the power supply supplies power to the control device and the alarm device. The water level detector can monitor whether the water level of a water tank of the solar water heater is in a safe range, and if the water level is higher than a preset upper limit or lower than a preset lower limit of the water level, an alarm lamp and the alarm device give out alarm so as to avoid leakage which is caused by overlarge water filling of the water tank and lead to short service life. The water level detector is simple in structure and easy to implement.
Description
Technical field
The utility model relates to a kind of water level detection gauge, particularly a kind of water level detection gauge that is used for the domestic solar water heater.
Background technology
At present, a lot of families all using the domestic solar water heater, water usually can occur and fill with the situation of overflowing behind the water tank in the use, cause waste, reduce water heater serviceable life.Do not have the water level detection gauge that this type of is applicable to the domestic solar water heater in the market.
The utility model content
The purpose of the utility model provides a kind of domestic solar water heater's of being used for water level detection gauge, can monitor the solar water heater water tank water level and whether be in safe range.
The utility model adopts following technical proposals:
A kind of water level detection gauge; Comprise power supply, condensate tank of dehumidifier, control device and warning device; The signal output part of condensate tank of dehumidifier connects the signal input part of control device; The signal output part of control device connects the signal input part of warning device, and power supply is control device and warning device power supply.
Described condensate tank of dehumidifier comprises buoyancy aid and the connecting link that is arranged in the water tank; One end of connecting link is provided with buoyancy aid; The other end of connecting link is provided with moving contact; Control device comprises first stationary contact, second stationary contact, electromagnetic relay and electromagnetic relay normally opened contact, and warning device comprises stationary contact, warning lamp and warning horn, and the moving contact of condensate tank of dehumidifier is connected positive source with the normally opened contact of electromagnetic relay; First stationary contact of control device is connected electromagnetic relay coil one end with second stationary contact; The electromagnetic relay coil other end connects power cathode, and the stationary contact of warning device is connected to positive source, and warning lamp and warning horn are connected to power cathode.
The utility model can be monitored the domestic solar cistern water level; If be higher than the water level upper limit that presets or be lower than the water level lower limit that presets, warning lamp and alarm are started working, and prompting gives the alarm; Can make and avoid Water flushing for cistern too much to cause leaking; Influence serviceable life, simple in structure, be easy to realize.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; The utility model comprises power supply, condensate tank of dehumidifier, control device and warning device; Said condensate tank of dehumidifier comprises the buoyancy aid 4 and connecting link 5 that is arranged in the water tank, and an end of connecting link 5 is provided with buoyancy aid 4, and the other end of connecting link 5 is provided with moving contact 1; Control device comprises first stationary contact 2, second stationary contact 3, electromagnetic relay 6 and electromagnetic relay normally opened contact 7; Warning device comprises stationary contact 8, warning lamp 9 and warning horn 10, and the moving contact 1 of condensate tank of dehumidifier and the normally opened contact 7 of electromagnetic relay are connected positive source, and first stationary contact 2 of control device is connected electromagnetic relay 6 coils one end with second stationary contact 3; The electromagnetic relay 6 coil other ends connect power cathode, and the stationary contact 8 of warning device, warning lamp 9 and warning horn 10 are connected to power cathode.
At cistern water level just often, moving contact 1 does not all contact with first stationary contact 2, second stationary contact 3, and circuit is in off-state, and warning lamp 9 is not all worked with warning horn 10;
When cistern water level was lower than setting value, moving contact 1 contacted with first stationary contact 2, electromagnetic relay 6 energising work; Since the electromagnetic effects that electromagnetic relay 6 produces, normally opened contact 7 and stationary contact 8 adhesives, circuit turn-on; Warning lamp 9 is started working with alarm 10, and prompting gives the alarm.
When cistern water level was higher than setting value, moving contact 1 contacted with second stationary contact 3, electromagnetic relay 6 energising work; Since the electromagnetic effects that electromagnetic relay 6 produces, normally opened contact 7 and stationary contact 8 adhesives, circuit turn-on; Warning lamp 9 is started working with alarm 10, and prompting gives the alarm.
