The air conditioner can produce the comdenstion water in the course of working, and the comdenstion water needs in time to discharge the air conditioner in order to guarantee the normal operating of air conditioner.

The problem that water leakage is difficult to cause by air conditioner drainage is common in the use of air conditioners and is generally caused by problems of air conditioner installation positions and pipelines. For example: the indoor unit of the air conditioner is lower than the outdoor unit, the air conditioner is low, the water outlet is high, the pipeline is blocked, and the like, so that water cannot be discharged, and the water leakage problem is caused.

In order to solve the problem of difficult drainage of an air conditioner, in the prior art, the drainage pump of the air conditioner is used for lifting the condensate water after the drainage of the air conditioner is improved, so that the problem that the water cannot be drained is solved.

The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the contact generating device includes a water storage tank 1. The water storage tank 1 is connected with a top cover 2. The top cover 2 is connected with the water storage tank 1 through detachable connection modes such as clamping connection and screw connection.

One side of the water storage tank 1 is provided with a water inlet 3 for connecting condensed water generated by an air conditioner to enter the water storage tank 1. An open slot 4 is arranged on one side of the top cover 2 close to the water inlet 3. The open slot 4 is used for penetrating through the water outlet pipe and enabling the water outlet pipe to enter the water storage tank 1 to be connected with a drainage pump in the water storage tank 1.

The core technical points of the application are as follows:

as shown in fig. 3, 4 and 5, the bottom of the top cover 2 is provided with a hinge post 5. The hinged column 5 is hinged with a float 6. When the condensed water generated during the operation of the air conditioner continuously enters the water storage tank 1, the liquid level in the water storage tank 1 gradually rises. So that the contact area between the buoy 6 and the condensed water is gradually increased, and the buoy 6 rotates around the hinge post 5 under the driving of buoyancy.

Correspondingly, as shown in fig. 6, two contact rods 7 are arranged on the top of the float 6. A switch 8 is arranged on the top cover 2 corresponding to the contact rod 7. One side of the switch 8 is connected with a switch sheet 9. Wherein, the switch 8 can be a sensitive switch 8 such as a tact switch 8, a micro switch 8 or a push switch 8, etc. for controlling the on-off of the drainage pump. When the contact rod 7 contacts the switch sheet 9 and forces the switch sheet 9 to lift and push, the switch 8 controls the drainage pump to start to lift and drain the condensed water in the water storage tank 1.

Preferably, two switches 8 are provided, both electrically connected to the drain pump. Wherein, the two switches 8 are respectively an on-off switch 10 and a safety switch 11. When the liquid level of the water storage tank 1 rises to enable the contact rod 7 to be pushed to contact the switch sheet 9, the on-off switch 10 controls the drainage pump to start and discharge the condensed water in the water storage tank 1, the liquid level in the water storage tank 1 is enabled to fall, the buoy 6 swings clockwise, the contact rod 7 is enabled to be far away from the switch sheet 9, and the drainage pump is turned off.

When on-off switch 10 trouble for under the unable condition of opening of drain pump when contact lever 7 contact supports and pushes away switch piece 9, the liquid level in the storage water tank 1 continues to rise, and at this moment, cursory 6 continues to rotate anticlockwise under the buoyancy effect, thereby makes contact lever 7 contact the switch piece 9 that belongs to safety switch 11 one side, thereby makes safety switch 11 open, and the drain pump starts to carry out the drainage and handles, prevents because the comdenstion water is too much spills over storage water tank 1, prevents the comdenstion water seepage. Wherein, the position of the switch sheet 9 belonging to the safety switch 11 can be set higher than the position of the switch sheet 9 belonging to the on-off switch 10, or the height of the contact rod 7 contacting the switch sheet 9 of the safety switch 11 can be set lower than the height of the contact rod 7 contacting the switch sheet 9 of the on-off switch 10.

Among the prior art, to above-mentioned auto-induction water level and start the device that the drain pump carries out drainage treatment to storage water tank 1 when certain liquid level, generally through setting up the stand between top cap 2 and storage water tank 1, the floater is established to the cover on the stand, through sensor induction floater when the floater rises to certain liquid level at the liquid level to make the drain pump start. However, the failure rate and sensitivity through electronic transmission are relatively poor compared with the present application because the present application does not cooperate with the sensor sensing through the floating of the floating ball, but rather, through the way that the mechanical contact is pushed against, the float 6 is utilized to rotate the starting switch 8 so that the drainage pump performs the drainage work. Whole journey need not the electronic information transmission, and the fault rate is low to, because the float 6 is the rotation mode, connection stability is high, and the motion of floater is in mixed and disorderly state in the turbulent flow, because the floater is beated to comparatively acutely leading to of the flow of water when the liquid level risees, can take place drainage processing when not reaching corresponding liquid level promptly, generally speaking has increased the start-up number of times of drain pump, and sensitivity is low and reduces the life of drain pump.

In addition, when the on-off switch 10 contacts and pushes against the contact rod 7, the float 6 is in a horizontal state. In this state, the accuracy of the contact pushing is highest.

With respect to the float 6, as shown in fig. 5, the present application further provides an arc block 12 at the bottom of the float 6 remote from the hinge post 5. The arc block 12 improves the contact area of the whole float 6 and the condensed water on one hand, so that the buoyancy is improved, and on the other hand, the adhesion phenomenon between the whole float and the bottom of the water storage tank 1 in the water-free state is prevented. In addition, the arrangement of the arc block 12 causes the gravity center of the float 6 to deviate towards one side, which is beneficial to keeping water balance and preventing the float 6 from swinging or jumping randomly under the turbulent state of condensed water to cause the condition of touching the switch piece 9 by mistake. In addition, arc block 12 is protruding to the direction of keeping away from switch 8, can make under anhydrous state, arc block 12 and storage water tank 1 butt prevent that storage water tank 1 from taking place the adhesion phenomenon with float 6.

As shown in fig. 7, the top cover 2 is further provided with first posts 13 at two sides of the switch 8 and a second post 14 at the middle. An installation groove 15 for installing the switch 8 is formed between the first column body 13 and the second column body 14. The switch 8 is clamped in the mounting groove 15 for stable mounting. The top of the first column 13 is provided with a positioning piece 16. The positioning piece 16 can abut against the top of the switch 8 when the switch 8 is installed in the installation groove 15, and the positioning piece 16 is provided with a slope 17. On one hand, the switch 8 can be guided to be installed, and on the other hand, the switch 8 can be placed better to be separated from the installation groove 15.

In order to better ensure the installation stability of the switches 8, a connecting plate 18 corresponding to the second column 14 is arranged between the two switches 8 in the present application. Two connecting columns 19 are arranged on two sides of the connecting plate 18. The corresponding switch 8 is provided with a connecting hole 20 matched with the connecting column 19. When the two switches 8 are installed, the two switches 8 are integrated by inserting the connection post 19 into the connection hole 20 of the two switches 8.

Then, the two switches 8 are connected with the connecting plate 18 and clamped into the two mounting grooves 15 together, so that the positioning pieces 16 on the two sides are matched to stably fix the two switches 8 integrally.

The reason for the above arrangement is that, because the condensed water is not in the advection state in the water storage tank 1, not only new condensed water enters the water storage tank 1 and affects the balance of water, but also because the air conditioner water discharge pump is arranged on the wall surface, the vibration generated by the air conditioner external unit damages the balance of water, so that the water is in a continuous turbulent state, therefore, if the installation stability of the switch 8 is not enough, the position of the switch 8 is easy to deviate, thereby causing the position change of the switch sheet 9, and causing the overflow or too many times of starting the water discharge pump due to the contact of the switch sheet 9 with the contact rod 7 too early or too late, through the above arrangement, the installation stability of the switch 8 can be well ensured, and the sensitivity of the switch 8 in controlling the water discharge pump is improved.

The application also relates to an air conditioner drainage pump, which applies the contact generating device. Also comprises a box body 21 and a cover body 22 matched with the box body 21. The arrangement of the remaining pumps and pipes is prior art and will not be described in detail.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
