Description
Technical field
The invention belongs to technical field of drainage, and in particular to a kind of draining pump and air-conditioning.
Background technology
It is well known that existing typically carry out draining using draining pump, simultaneously because in actual use, the height of drainpipe
Degree is higher than draining pump, then current are likely occurred in drainage procedure and flow backwards the phenomenon entered in the draining pump pump housing, are caused to row
The pollution of water pump and breed bacteria, especially when draining pump is applied to household electrical appliance, such as air-conditioning, dish-washing machine are this to flow backwards now
As even more undesirable.It is existing that unidirectional fluid stopping is typically set in drainage pipeline in order to avoid this refluence phenomenon occurs
Structure, current unidirectional fluid stopping structure are typically configured complex, have more installed part, and installation accuracy requirement is strict, and
Installing space demand is big, is not easy to be installed in drainage pipeline.Below by taking air-conditioning as an example, its background technology is introduced：
Air-conditioning inevitably produces condensed water when working and running, it is therefore desirable to sets discharge structure will be cold on air-conditioning
Condensate is discharged in time.Existing conventional air-conditioning drainage pump schematic diagram shown in Figure 1, specifically include for taking up condensed water
Tank 110, the draining pump 120, the internal drainage pipe 130 in air-conditioning and outer outside air-conditioning that are placed in tank 110
Portion's drainpipe 140, wherein, draining pump 120, internal drainage pipe 130 and outer row water pipe 140 are sequentially connected, and draining pump 120 is by water
Condensed water in groove 110 is discharged eventually through outer row water pipe 140.Because draining pump is without single slope drainage structure, and in draining
Condensed water is likely occurred in journey to flow backwards, especially in the actual installation of air-conditioning, the discharge outlet one of outer row water pipe 140
As be higher than draining pump 120 discharge outlet, it is therefore necessary to existing discharge structure is improved, to avoid condensed water from flowing backwards
The problem of.In order to solve the problems, such as that condensed water flows backwards, current optimisation technique is that internally installation is single in drainpipe 130
To valve 150, as shown in the arrow in Fig. 1 at check valve 150,150, check valve allows current to be flowed out from drainage direction, without permitting
Perhaps flow reversal is flowed into draining pump 120, but the structural member of existing check valve 150 is more, generally comprises 5 installed parts,
Installing space demand is big, and internally the installation operation in drainpipe 130 is relatively inconvenient.
As Publication No. CN101592367A discloses a kind of anti-backflow device of the indoor set condensed water for air-conditioning, tool
Body includes the more than one stop part for allowing scupper hose inner open convexed to form；Formed in the opposite side of stop part, envelope
The cover closed inside scupper hose；It is prominent from the inside of connecting tube to center position, it is allowed a choice with the side of stop part and cover
Ground contacts, and allows the inner open of connecting tube or the anti-backflow portion of closing.The patent is by cover, stop part and positioned at connecting tube
Anti-backflow portion cooperates and realizes anti-backflow effect, complicated, and installation accuracy requires high, and manufacturing cost is higher.
It is therefore still necessary to seek a kind of water discharge method of draining pump to solve the technical problem of the above.
The content of the invention
In view of this, it is an object of the invention to provide a kind of draining pump and air-conditioning, effectively avoid flowing backwards phenomenon
While, simple in construction, compact, easy for installation, manufacturing cost is low.
To achieve these goals, technical scheme provided by the invention is as follows：
A kind of draining pump, including the pump housing and pump housing delivery port, wherein, described pump housing water outlet is provided with unidirectional fluid stopping
Structure.

Discharge outlet be connected, first mouth of pipe and second mouth of pipe have the first internal diameter and the second internal diameter respectively；
Is provided with ball in the unidirectional fluid stopping structure, the ball external diameter is more than first internal diameter, and is less than described the
Two internal diameters；
Being fixedly installed on second mouth of pipe has the water outlet limiting section of hydrospace, for the spacing of the ball.
Preferably, the pump housing delivery port is in tapered shape.
Preferably, the water outlet limiting section includes water outlet wall and delivery port, the water outlet wall and the pump housing delivery port
Tube wall is fixedly connected, and the delivery port connects with second mouth of pipe, and the delivery port internal diameter is more than ball external diameter, the water outlet
Some position-limited edges are fixed with wall, the position-limited edge is connected some spaces to be formed with the water outlet wall as the water outlet
Space, and the maximum circular cross-section product in each space is less than the maximum secting area of the ball, for the spacing of the ball.
Preferably, the position-limited edge further comprises：Circular position-limited edge positioned at the delivery port center, for the rolling
The center of pearl is spacing.
Preferably, the circular position-limited edge is handled using chamfer angle technique, and the conical surface is formed around the circular position-limited edge.
Preferably, the ball is made of plastics or elastomeric material.
Preferably, the water outlet wall is fixed by the tube wall of screw thread or bonding or interference mode and the unidirectional fluid stopping structure
Connection.
Preferably, a kind of air-conditioning, including for taking up the tank of condensed water, and the draining pump in tank, wherein, institute
State draining pump and use draining pump as described above.
Preferably, the drainpipe includes the internal drainage pipe in air-conditioning and the outer row water pipe outside air-conditioning,
The draining pump, internal drainage pipe and outer row water pipe are sequentially connected.
Present invention firstly provides the pump housing water outlet in draining pump to set unidirectional fluid stopping structure, specifically includes ball, together
When the unidirectional fluid stopping structure is set smaller than ball external diameter close to the first spout diameter of the pump housing, will be close to outer row water pipe
Second spout diameter is set greater than ball external diameter, while causes anti-backflow function in order to avoid ball departs from from pump housing delivery port
Failure, the present invention set the water outlet limiting section go out with hydrospace at second mouth of pipe, spacing for being carried out to ball, thus
In use, ball can be according to normally forward draining is entered different shapes with when inversely flowing backwards by the bourn acting force of different directions
State；Specifically, normally forward draining when, ball is moved, until movement to outside drainpipe direction by forward drainage power
To water outlet limiting section, the pump housing realizes proper drainage by the hydrospace that goes out realized on water outlet limiting section, when reverse flow backwards occurs,
Ball is moved by active force is flow backwards to the first mouth of pipe direction, until being blocked by the internal diameter of pump housing delivery port, while realizes to pump
The sealing of body delivery port, pump housing delivery port are closed, therefore be effectively prevent current and flow backwards into the pump housing of draining pump, and structure is non-
Often simple, compact, processing, installation are very convenient, and manufacturing cost is low, are appropriate for scale popularization and application, the present invention is especially
