As shown in fig. 1, an electrical apparatus (not shown) according to an embodiment of the present invention is provided with a water sealing structure 100 for draining water. The structure of the mid-water seal structure 100 according to the present application will be described below, taking an electrical appliance as a condensing 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 wall-hanging condensing furnace may be embodied as other devices equipped with the water sealing structure 100, and is not limited herein.
The water sealing structure 100 includes a pipeline main body 20 and a detection module 40, wherein the pipeline main body 20 includes a water inlet pipeline, a water outlet pipeline 23, a first connection pipeline 25 and a second connection pipeline 27. Wherein, the inlet channel is connected with the main body of the wall hanging stove of condensing type in order to obtain the exhaust comdenstion water of main body, and drainage pipe 23 communicates the inlet channel through first connecting tube 25 and second connecting tube 27 in order to discharge the comdenstion water. The detection module 40 is installed at one end of the drainage pipeline 23 connected with the first connecting pipeline 25, and the detection module 40 is used for detecting a water flow signal at a preset detection position. In the direction of gravity, the first connecting duct 25 is located above the second connecting duct 27, and the predetermined detection position is located below the first connecting duct 25 and above the second connecting duct 27.
In the water seal structure 100, the pipe main body 20 is communicated with the main body of the wall-mounted condensing boiler to discharge condensed water generated by the wall-mounted condensing boiler during operation, and the detection module 40 is used for detecting whether the pipe main body 20 is blocked or not to ensure smooth discharge of the condensed water. As shown in fig. 2, when the water seal structure 100 is normally drained, the condensed water flows from the water inlet pipe into the drain pipe 23 through the second connection pipe 27 located below the first connection pipe 25 and is drained. As shown in fig. 3, when the water sealing structure 100 is blocked, the condensed water which cannot be discharged through the drainage pipeline 23 continuously rises until the first connecting pipeline 25 is filled, and the detection position is lower than the first connecting pipeline 25 in the gravity direction, so that the detection position is submerged by the condensed water, the detection module 40 detects a water flow signal, thereby triggering the protection function of the condensing wall-hanging stove, and the condensing wall-hanging stove stops and reports the fault, thereby avoiding the backflow of the condensed water.
With continued reference to FIG. 1, the water inlet pipe includes a separation section 212, a first water inlet section 214, a water inlet connection section 216, and a second water inlet section 218 connected in series.
Specifically, the separation section 212 extends in a curved shape, and includes a first separation part 2121, a first separation connection part 2123, a second separation part 2125, and a second separation connection part 2127 connected in this order. The water inlet end of the first separating part 2121 is connected to the main body of the wall-mounted condensing furnace, the first separating part 2121 extends vertically downward from the water inlet end thereof along the gravity direction, and the water outlet end of the first separating part 2121 is connected to the water inlet end of the first separating connecting part 2123. The first separating connecting part 2123 extends from the first separating part 2121 in a curved shape to form a semi-circular arc shape protruding downward in the gravity direction, and a water outlet end of the first separating connecting part 2123 is connected to a water inlet end of the second separating part 2125. The second separating portion 2125 extends vertically upward from the water inlet end thereof in the antigravity direction, and the water outlet end of the second separating portion 2125 is connected to the water inlet end of the second separating connecting portion 2127. The second separating connecting part 2127 extends from the second separating part 2125 in a curved shape to form a semi-circular arc shape protruding upwards along the antigravity direction, and the water outlet end of the second separating connecting part 2127 is connected to the water inlet end of the first water inlet section 214.
In this way, the condensed water output from the main body of the wall-hanging condensing furnace first enters the first separating portion 2121, flows downward in the first separating portion 2121 in the direction of gravity to the first separating connecting portion 2123, then turns 180 ° in the first separating connecting portion 2123 to enter the second separating portion 2125, then flows upward in the second separating portion 2125 in the direction of counter-gravity to the second separating connecting portion 2127, and finally turns 180 ° in the second separating connecting portion 2127 to flow into the first water inlet section 214. Therefore, the condensed water flows in the separation section 212 in a winding manner to form a section of water pressure to separate the condensed water from the flue gas, thereby preventing the flue gas from being discharged through the water seal structure 100 to cause potential safety hazards and environmental pollution. It will be appreciated that the particular configuration of the separation section 212 is not so limited and may be provided in different shapes as desired.
The water inlet end of the first water inlet section 214 is connected to the water outlet end of the second separation connecting part 2127 of the separation section 212, the first water inlet section 214 extends vertically downwards from the separation section 212 along the gravity direction, and the water outlet end of the first water inlet section 214 is connected to the water inlet end of the water inlet connecting section 216. The first water inlet section 214 is provided with a first water outlet at an end close to the separation section 212, so that the first water inlet section 214 is connected to one end of the first connecting pipe 25 through the first water outlet. The water inlet connecting section 216 extends from the first water inlet section 214 in a curved shape in a semi-circular arc shape protruding downwards along the gravity direction, and the water outlet end of the water inlet connecting section 216 is connected with the water inlet end of the second water inlet section 218. The second water inlet section 218 extends vertically upward from the water inlet connection section 216 in the antigravity direction to connect the water inlet end of the drain pipe 23. The second water inlet end of the second water inlet section 218 is provided with a second water outlet, so that the second water inlet section 218 is communicated with one end of the second connecting pipeline 27 through the second water outlet. It will be appreciated that in other embodiments, the end of the second water inlet section 218 remote from the water inlet connection section 216 may not be in communication with the drain conduit 23.
Thus, as shown in fig. 2, when the water seal structure 100 drains, the condensed water entering the first water inlet section 214 flows downward to the water inlet connecting section 216 along the gravity direction, turns 180 ° in the water inlet connecting section 216, enters the second water inlet section 218, flows upward along the antigravity direction in the second water inlet section 218, and finally flows into the water discharge pipeline 23 through the second connecting pipeline 27.
With continued reference to fig. 1, the drain line 23 includes a detection section 232 and a drain section 234. Wherein, both ends of the detection section 232 are connected to one end of the first connection pipe 25 and one end of the drainage section 234, respectively. The detection section 232 is bent and extends to form an upward convex arc, in the gravity direction, the bottom wall of the detection section 232 is lower than the bottom wall of the first connecting pipeline 25, the height of the top wall of the detection section 232, which is higher than the top wall of the first connecting pipeline 25, is higher than the position of the bottom wall of the first connecting pipeline 25 at a preset detection position. One end of the detection module 40 extends into the detection section 232 from the top wall of the detection section 232 and extends to a preset detection position along the gravity direction. Thus, when the water sealing structure 100 is blocked, the condensed water is continuously collected in the drainage pipeline 23 until the drainage pipeline is full of the first connecting pipeline 25, and the detection module 40 can detect the water flow signal inevitably even if the operation of the wall-mounted condensing furnace is stopped because the preset detection position is lower than the first connecting pipeline 25.
The drain section 234 extends vertically downward in the direction of gravity from the detection section 232. The drainage section 234 includes a first water inlet and a second water inlet, and the first water inlet is located above the second water inlet in the direction of gravity. The first water inlet is located at the top end of the water discharging section 234, the water discharging section 234 is communicated with one end of the detecting section 232 through the first water inlet, the second water inlet is located at the middle lower part of the water discharging section 234, and the water discharging section 234 is communicated with the water outlet end of the second connecting pipeline 27 through the second water inlet.
So, when water seal structure 100 normally drains, the comdenstion water passes through second connecting tube 27 and gets into drainage section 234 through the second water inlet, then flows downwards under the action of gravity, all does not have the comdenstion water in drainage section 234 and the detection section 232 above the second water inlet this moment, therefore detection module 40 can't detect the rivers signal, but condensing hanging stove normal operating.
The water flow state of the water seal structure 100 under the normal drainage state is as follows:
the condensed water flows through the separation section 212 of the water inlet pipe, the first water inlet section 214 and the lower portion of the second water inlet section 218 in sequence, then enters the water discharge section 234 of the water discharge pipe 23 through the second connection pipe 27, is lower than the lower portion of the second connection pipe 27, and finally flows out of the water discharge section 234. In the process, no condensed water is present in the drainage section 234 above the second connecting pipe 27, the detection section 232, the first connecting pipe 25 and the second water inlet section 218 above the second connecting pipe 27, so that the detection module 40 does not detect the water flow signal.
The water sealing structure 100 has the following water flow conditions in the abnormal drainage condition:
the water levels in the drainage pipe 23 and the second water inlet section 218 continuously rise along with the inflow of the condensed water until the condensed water enters the detection section 232 and the first connection pipe 25. When the condensed water is over the detection module 40, the detection module 40 detects a water flow signal, so that the shutdown protection function of the condensing wall-mounted furnace is triggered, and the condensed water is prevented from flowing backwards to damage the main body of the condensing wall-mounted furnace.
In the water seal structure 100 and the electrical equipment provided with the same, since the water inlet pipeline is communicated with the drainage pipeline 23 through the second connecting pipeline 27 which is not located at the topmost end, when the water seal structure 100 can drain water normally, condensed water is drained into the drainage pipeline 23 through the second connecting pipeline 27 and then is drained. When the water seal cannot drain normally, the condensed water is accumulated continuously in the water seal structure 100 to submerge the preset detection position, so that the detection module 40 can detect a water flow signal to trigger the protection function of the electrical equipment, the electrical equipment is stopped in time to prevent the condensed water from flowing backwards, and the stable operation of the electrical equipment is effectively protected.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
