Description
Technical field
The utility model relates to Compressor Technology field, in particular to a kind of sucking sound-muffling box and frequency-changeable compressor.
Background technique
General reciprocating compressor has been difficult to keep up with various countries' efficiency grade, variable-frequency reciprocating pressure because of its design feature efficiency
The appearance of contracting machine effectively improves old twin compressor disadvantage；Variable-frequency reciprocating compressor efficiency higher grade, operating is with small vibration,
It is more stable, noise is smaller, therefore variable-frequency reciprocating compressor has good development prospect in middle and high-end market.
When operating in a high frequency, up to 4500 turns per minute, run at high speed takes up maximum speed variable-frequency reciprocating compressor
Lubricants capacity is very big, and lubricating oil is flown to spill by crankshaft top with circumference, knock sucking the sound-muffling box back side can splash after along suction
Enter noise reduction box cover to flow down, is easily inhaled the suction inlet sucking of sound-muffling box, causes compressor to spit oil, to influence overall performance；
In addition it but will shorten compressor service life when compressor memory oil mass is too small.
Utility model content
The purpose of this utility model is to propose a kind of sucking sound-muffling box and frequency-changeable compressor, solves and compresses in the prior art
Compressor splashing is easily inhaled sound-muffling box sucking when machine operates, and compressor is caused to spit oil, shortens compressor and uses
The problem of service life.
One aspect according to the present utility model provides a kind of sucking sound-muffling box, comprising:
The side of bottom cover, bottom cover is equipped with a suction inlet；
Top cover, lid are located at the upper end of bottom cover, and the upper top surface of top cover is convexly equipped in an inclined manner along the sprinkling direction of lubricating oil
One gear oil groove, to guide lubricating oil to avoid suction inlet.
Further, oil groove is arc-shaped and its both ends extends to the side of top cover for gear.
Further, the rear side of suction inlet is arranged in close to one end of suction inlet for gear oil groove.
Further, the surrounding outer rim of suction inlet is convexly equipped with protrusion.
On the other hand according to the utility model, a kind of frequency-changeable compressor is provided, including above-mentioned sucking sound-muffling box
The technical effect of the utility model: the utility model is being disappeared by the way that gear oil groove is added at the top of sucking sound-muffling box
Protrusion is arranged in the outer rim of the suction inlet of sound box, and when frequency-changeable compressor has run at high speed, lubricating oil is flown to spill by crankshaft top with circumference
Out, knock sucking noise reduction box top can splash after along sucking noise reduction box cover flow down, to gear oil groove when along keep off oil groove flow to
One side finally flows back to compression motor spindle, avoids sucking sound-muffling box suction inlet, efficiently reduces suction inlet sucking lubricating oil
Probability.

Specific embodiment
To make the objectives, technical solutions and advantages of the present invention clearer, With reference to embodiment
And referring to attached drawing, the utility model is further described.It should be understood that these descriptions are merely illustrative, and do not really want
Limit the scope of the utility model.In addition, in the following description, descriptions of well-known structures and technologies are omitted, to avoid not
Necessarily obscure the concept of the utility model.
In the description of the present invention, it should be understood that term " center ", " longitudinal direction ", " transverse direction ", "front", "rear",
The orientation or positional relationship of the instructions such as "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" is based on attached drawing institute
The orientation or positional relationship shown, is merely for convenience of describing the present invention and simplifying the description, rather than indication or suggestion is signified
Device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as to this is practical
The limitation of novel protected range.
As shown in Figures 1 and 2, one aspect according to the present utility model provides a kind of sucking sound-muffling box, comprising:
The side of bottom cover 12, bottom cover 12 is equipped with a suction inlet 121；Top cover 11, lid are located at the upper end of bottom cover 12, top cover 11
Upper top surface is convexly equipped with a gear oil groove 111 along the sprinkling direction of lubricating oil in an inclined manner, to guide lubricating oil to avoid suction inlet
121.Specifically, it sucks among the top cover 11 of sound-muffling box 1 and swells upwards, gradually decreased outward from centre, in other words, top cover
11 top surface is inner high outer low；When lubricating oil flies to spill from 22 top of crankshaft with circumference, sucking 1 top cover 11 of sound-muffling box is knocked
It is flowed down after having splashed on top surface along top cover 11, finally flows back to compression along gear 111 inclined direction of oil groove to when keeping off oil groove 111
2 bottom of machine, thus avoids suction inlet 121, efficiently reduces the probability that suction inlet 121 sucks lubricating oil, avoids pressure
Contracting machine 2 spits the phenomenon of oil, improves the overall performance of compressor 2.
In a preferred embodiment, oil groove 111 is arc-shaped and its both ends extends to the side of top cover 11 for gear.Specifically
, as shown in Figure 1, gear oil groove 111 is set as arc along the direction that lubricating oil sprays and keeps off oil groove 111 from left avertence to Right deviation
The both ends of tiltedly setting, gear oil groove 111 extend to the side of top cover 11, so that side fair current of the lubricating oil along gear oil groove 111
To 2 bottom of compressor, guarantees that the lubricating oil trapped fuel amount of 2 bottom of compressor increases, avoid 2 memory oil mass of compressor too small and then contract
The service life of short compressor 2.
As shown in Fig. 2, in a preferred embodiment, the surrounding outer rim of suction inlet 121 is convexly equipped with protrusion 1211.It is inhaling
The periphery setting of entrance 121 surrounds the protrusion 1211 of suction inlet 121, prevents a small amount of lubricating oil from avoiding gear oil groove 111 from top cover
11, which go downstream, is inhaled into the sucking of mouth 121, further reduces the probability that suction inlet 121 sucks lubricating oil.
As shown in figure 3, on the other hand according to the utility model, a kind of frequency-changeable compressor 2 is provided, including above-mentioned sucking
Sound-muffling box 1.Specifically, compressor 2 includes casing 21 arranged at the bottom, the crankshaft 22 among casing 21 is set, and sucking disappears
The side in casing 21 is arranged in sound box 1, and discharge sound-muffling box 23 and sucking sound-muffling box 1 are oppositely disposed in casing 21.
The utility model is by the gear of projection one oil groove at the top of sucking sound-muffling box, and the outer rim of the suction inlet in sound-muffling box is set
Protrusion is set, lubricating oil is flown to spill by crankshaft top when frequency-changeable compressor has run at high speed with circumference, is knocked sucking sound-muffling box 1 and is carried on the back
Face flows down after having splashed along sucking noise reduction box cover, finally flows back to compressor bottom to a side is flowed to along oil groove when keeping off oil groove
Portion avoids sucking sound-muffling box suction inlet, efficiently reduces suction inlet sucking lubricating oil probability.
It should be understood that the above-mentioned specific embodiment of the utility model is used only for exemplary illustration or explains this reality
With novel principle, without constituting limitations of the present invention.Therefore, in the spirit and scope without departing from the utility model
In the case of any modification, equivalent substitution, improvement and etc. done, should be included within the scope of protection of this utility model.In addition,
The appended claims for the utility model are intended to cover to fall into attached claim scope and boundary or this range and boundary
