As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1, an electrical apparatus (not shown) according to an embodiment of the present invention includes a drainage structure 100 for draining water. The structure of the center drain structure 100 according to the present application will be described below by taking an electric appliance as a wall-hanging stove as an example. The following examples are given by way of illustration only and are not intended to limit the scope of the present application. It is understood that in other embodiments, the electrical device may also be embodied as other appliances installed with the drainage structure 100, and is not limited herein.

The drain structure 100 includes a water inlet pipe 20, a water outlet pipe 40, and a water sealing device 60. The central axis of inlet tube 20 is coaxial with the central axis of drain pipe 40 and extends along the direction of gravity, and the end of intaking of inlet tube 20 is connected with the main fuselage of hanging stove, and in the comdenstion water that the main fuselage flows got into inlet tube 20, the play water end of drain pipe 40 was connected with structures such as floor drain in order to arrange the comdenstion water to external environment, and the play water end of inlet tube 20 is connected through water seal 60 with the end of intaking of drain pipe 40.

The water seal arrangement 60 comprises a main pipe 61, an overflow pipe 63 and a detection assembly 65. When the drainage structure 100 is in a normal drainage state, the condensed water flowing out of the water inlet pipe 20 enters the water outlet pipe 40 through the main pipe 61, no condensed water flows through the overflow pipe 63, and the wall-hanging stove is in a normal working state. When drainage structure 100 is in the jam state and can't discharge the comdenstion water smoothly, the comdenstion water constantly accumulates in trunk line 61 and gets into overflow pipe 63, and after the water level reached a take the altitude, detection component 65 sent signal to the main fuselage, and the hanging stove switches to the shutdown protection state according to the signal to avoid the comdenstion water to flow back to in the main fuselage and damage the main fuselage.

Specifically, the main pipe 61 includes a first water inlet end 612 and a first water outlet end 614 which are communicated with each other, the first water inlet end 612 is connected to the water outlet end of the water inlet pipe 20, the first water outlet end 614 is connected to the water inlet end of the water outlet pipe 40, and the first water outlet pipe 40 extends linearly from the first water inlet end 612 to the first water outlet end 614 along the gravity direction. Thus, when the drainage structure 100 is in a normal drainage state, the condensed water flowing out of the water inlet pipe 20 flows through the main pipe 61 into the drainage pipe 40 by gravity.

The overflow conduit 63 is connected between the first inlet end 612 and the first outlet end 614 of the main conduit 61. The detection assembly 65 is mounted to the overflow pipe 63, and is configured to emit a light beam passing through the overflow pipe 63 in a radial direction of the overflow pipe 63, and acquire a light intensity of the light beam passing through the overflow pipe 63 to control an operating state of the electrical appliance according to the magnitude of the light intensity.

In this way, when the drainage structure 100 is in the normal drainage state, the condensed water flows into the drainage pipe 40 only through the main pipe 61 under the action of gravity without entering the overflow pipe 63, so that the light beam emitted by the detection assembly 65 passes through the air in the overflow pipe 63 with a small attenuation degree, the light intensity of the light beam passing through the overflow pipe 63 is large, and the wall-hanging stove is in the normal operation state. When the drainage structure 100 is in a blocked state, the condensed water cannot be effectively drained from the drainage pipe 40, so that the condensed water gradually accumulates in the main pipe 61 and finally enters the overflow pipe 63, and the light beam emitted by the detection assembly 65 passes through the condensed water in the overflow pipe 63 with a large attenuation degree, so that the light intensity of the light beam passing through the overflow pipe 63 is small. At this moment, the wall-mounted furnace reports the fault and enters a shutdown protection state, so that condensed water is prevented from overflowing the drainage structure 100 to enter the main body of the wall-mounted furnace, the condensed water is prevented from damaging parts in the main body, and the fault rate of the wall-mounted furnace is reduced.

Specifically, the overflow pipeline 63 includes a second water inlet end and a second water outlet end that are communicated with each other, the second water inlet end and the second water outlet end are respectively connected to the main pipeline 61, and the second water outlet end is located between the second water inlet end and the first water inlet end 612. Thus, when the drainage structure 100 is gradually blocked and cannot drain normally, the condensed water continuously accumulated in the main pipe 61 enters the overflow pipe 63 through the second water inlet end, and the condensed water can return to the main pipe 61 through the second water outlet end after the overflow pipe 63 is filled with the condensed water. Therefore, the two ends of the overflow pipeline 63 are respectively connected with the main pipeline 61, so that the phenomenon that air cavities occur in the overflow pipeline 63 due to the fact that gas cannot be discharged is avoided, and the detection accuracy of the detection assembly 65 is improved.

Specifically, in one embodiment, the overflow pipe 63 includes a first overflow section 632, a second overflow section 634 and a third overflow section 636 connected in sequence. The second overflow section 634 is connected between the first overflow section 632 and the third overflow section 636, one end of the first overflow section 632, which is far away from the second overflow section 634, is connected to the main pipe 61 and forms a second water inlet end, and one end of the third overflow section 636, which is far away from the second overflow section 634, is connected to the main pipe 61 and forms a second water outlet end. The first overflow section 632 and the third overflow section 636 both extend in the horizontal direction, and the second overflow section 634 extends in the gravity direction. It will be appreciated that the shape of the overflow conduit 63 is not limited thereto and may be provided in different shapes as desired.

Further, the detecting assembly 65 is disposed in the second overflow section 634, the detecting assembly 65 includes a light emitting module 652 and a light intensity detecting module 654, and the light emitting module 652 and the light intensity detecting module 654 are mounted on the sidewall of the overflow pipe 63 in the radial direction of the overflow pipe 63 in an opposite manner. Thus, the light emitting module 652 can emit a light beam passing through the overflow pipe 63 along the radial direction of the overflow pipe 63 to the light intensity detecting module 654, and the light intensity detecting module 654 is configured to obtain the light intensity of the light beam, so as to control the working state of the wall-hanging stove according to the light intensity.

The control method of the electrical equipment comprises the following steps:

s110: a light beam passing through the overflow channel 63 in a radial direction of the overflow channel 63 of the drain structure 100 is emitted, and the light intensity of the light beam after passing through the overflow channel 63 is acquired.

Specifically, the light emitting module 652 emits a light beam passing through the second overflow section 634 of the overflow duct 63 in the radial direction, and the light intensity detecting module 654 receives the light beam passing through the overflow duct 63 and acquires the light intensity of the light beam. Wherein the light intensity is determined by the number of photons impinging on a unit area per unit time.

S120: and controlling the electrical equipment to be in a normal operation state or a shutdown protection state according to the light intensity.

And when the light intensity is greater than the preset light intensity, controlling the electrical equipment to be in a normal working state. Specifically, when the drainage structure 100 is in a normal drainage state, no condensed water exists in the overflow pipe 63, so that the light beam emitted by the light emitting module 652 passes through the air in the overflow pipe 63 and is received by the light intensity detecting module 654, and since the attenuation of the light beam passing through the air is small, the number of photons detected by the light intensity detecting module 654 in a unit time is large, and the light intensity is larger than the preset light intensity, so that the wall-hanging stove operates normally.

And when the light intensity is smaller than the preset light intensity, controlling the electrical equipment to be in a shutdown protection state. Specifically, when the water seal structure is in a blocked state, the water level of the condensed water in the overflow pipeline 63 continuously rises until the condensed water passes through the detection assembly 65, so that the light beam emitted by the light emitting module 652 passes through the condensed water in the overflow pipeline 63 and then is received by the light intensity detection module 654, and since the attenuation of the light beam in the process of passing through the condensed water is large, the number of photons detected by the light intensity detection module 654 in unit time is small, and the light intensity is smaller than the preset light intensity, so that the wall-hanging furnace is in a shutdown protection state, and the condensed water is prevented from being discharged continuously to cause the condensed water to flow backwards into the main machine body.

According to the water seal device 60, the drainage structure 100, the electrical equipment and the electrical equipment control method, the working state of the drainage structure 100 is rapidly and accurately acquired through the detection assembly 65, so that the electrical equipment can timely enter a shutdown protection state after the drainage structure 100 is blocked, the problem that condensed water flows back to a burner or other parts is solved, and the failure rate of the electrical equipment is reduced.
