Embodiment
The present invention is described further below in conjunction with the drawings and specific embodiments.
Such as Fig. 1, Fig. 2, shown in Figure 4, a kind of buoy switch device with water level detecting, comprise unsteady trigger equipment, pressure triggering and trigger switch 10, described unsteady trigger equipment and pressure triggering are designed to one, it can make according to the variation of floating displacement or pressure described trigger switch 10 actions, wherein, pressure triggering comprises that the pedestal 2 which is provided with sealed air chamber 22 can transmit the pressure that described sealed air chamber 22 produces with being provided with, thereby produces the reed 5 that displacement touches trigger switch 10; Unsteady trigger equipment comprises the buoy 1 that is located at described pedestal 2 belows and is fixed on the described buoy 1 and can touches with the displacement of buoy 1 the buoy support 9 of trigger switch 10.
Described pedestal 2 is provided with location hole 23, and described buoy support 9 passes location hole 23 and is fixed on the buoy 1.
Being shaped as of described buoy support 9 is U-shaped.
Described sealed air chamber 22 is provided with the valve 21 that is communicated with and can transmits hydraulic pressure with it, and this valve 21 is circular tube shaped.
Also comprise the seal disc 3 that can seal described sealed air chamber 22 and which is provided with salient point 31, the supporting disk 4 that is provided with pressure location hole 41 and supporting disk support 42, wherein, seal disc 3 sealed air chamber 22 of packing into, salient point 31 buckles in the pressure location hole 41 on it, and supporting disk support 42 props up reed 5.
Described reed 5 is provided with the leaf support 51 that can touch trigger switch 10 and the reed groove 52 that can insert supporting disk support 42.
Described reed 5 is provided with the spring 6 that laterally clamps, and this spring 6 is volute spring.
Also comprise the loam cake 7 and the main pressing spring 8 that are provided with rack positioning hole 71 and location hole of the spring 73, wherein, loam cake 7 is installed in the sealed air chamber 22, leaf support 51 is passed rack positioning hole 71, main pressing spring 8 one ends pass location hole of the spring 73 and are installed on the reed 5, and main pressing spring 8 other ends are limited in the location hole of the spring 73 with screw 100.
Described loam cake 7 is provided with bracing frame 72, and described trigger switch 10 is fixed on the bracing frame 72.
Described trigger switch 10 is provided with and touches lever 90.
Operation principle of the present invention is: during water leakage monitoring, when inner bag leaks or the exterior line of inner bag when leaking, water can directly bleed in the chassis, and place buoy 1 in the chassis, can float gradually along with the increase of the chassis water yield, the buoy support 9 that is connected with buoy 1 highly rises, and buoy support 9 sends fault-signal with the shake-up lever 90 of pull switch 10.During Pressure monitoring, when washings enter in the internal cavity of bowl washer, increase with rate of water added, the level pressure (air pressure) that inner bag bottom produces is by tube connector 12(such as Fig. 3) valve 21 of pedestal 2 that passes through the float switch of water level monitoring enters in the sealed air chamber 22, air pressure makes seal disc 3 that deformation occur, the supporting disk support 42 that promotes on the supporting disk 4 moves upward, reed 5 is squeezed, and simultaneously deformation also occurs to move in volute spring and reed 5 in deformation, make main pressing spring 8 stress and deformations, water level in internal cavity of bowl washer exceeds normal height gradually, reed 5 compressional deformation power and volute spring acting in conjunction power overcome the active force of main pressing spring 8 gradually, leaf support 51 moves up and promotes to touch lever 90 and produces action, emits failure alarm signal.When the dishwasher draining, hydraulic pressure reduces gradually, and the pressure of sealed air chamber 22 reduces, the volute spring active force less than main pressing spring 8 active forces after, reed mechanism can revert to normal condition.The setting of critical point of reporting to the police in addition can come according to the requirement of product design Self-adjustment structure and controller.
Break down when reporting to the police, the user only need to open the dishwasher external door, comes failure judgement to derive from inner bag or water pipe leaks or the inner bag water level is too high to be caused according to the height of inner bag middle water level.Greatly reduce the complexity of troubleshooting effort.
Water leakage monitoring is to realize that by controlling different supports trigger switch sends alarm signal with pressure detecting in addition.So buoy support 9 also can be designed to different height and control respectively two switches.But technology of the present invention is not limited on the described embodiment, also is applicable to simultaneously on other products such as washing machine.
The present invention both can predict high water level, can measure the fault that water circuit system leaks again, prevent complicated detachable maintaining and false alarm signal with this, and cost was low, was easy to install, and saved the space, was suitable for promoting.
