A kind of coolant bin of domestic air conditioning
Technical field
This utility model belongs to consumer goods industries, relates to a kind of domestic air conditioning, the coolant of a kind of domestic air conditioning
Bin.
Background technology
The effect of the reservoir on air-conditioning is that the drain pipe of traditional reservoir is welded on reservoir for storing coolant
The lower end of body, in the unsettled inner chamber being placed in reservoir in the upper end of drain pipe, drain pipe relies on location, welding position fixing, due to
Drain pipe easily tilts when welding, and welding position size is little, and force-bearing situation is poor, and reservoir drain pipe in use is often
It is easily subject to damage.
For above-mentioned problem, it has been realized that deficiency, and improved, as disclosed in the Chinese patent storehouse one
Plant the coolant bin [application number: 201320126310.9 of domestic air conditioning;Authorization Notice No.: CN 203100307 U] include storage
Liquid device body, feed tube and drain pipe, feed tube is arranged at the upper end of body, through with chamber body, the position, one end of drain pipe
In reservoir body inner chamber, the other end is positioned at the outside of reservoir body, a part for drain pipe outer wall and reservoir body
Lower end welding, described reservoir also includes keeper, and keeper is fixed on the internal chamber wall of reservoir body, keeper will
The periphery wall of drain pipe upper end is fixed, and makes drain pipe parallel with reservoir body axis.
Drain pipe, by arranging keeper the most internal, is fixed, is prevented drain pipe from swinging, drain pipe by above-mentioned reservoir
One end stress and become two ends stress, prevent drain pipe from tilting, be hardly damaged during use, thus well solve existing
Problem present in technology.But this reservoir still there is a problem in that the installation of keeper and drain pipe and reservoir this
The sealing of body is connected all there is bigger requirement to machining accuracy and the quality of fit of parts in both, causes whole liquid storage
The processing of device and the difficulty of assembling are the biggest.

Annular seal groove and the 0 shape circle being located in annular seal groove, the outer peripheral face of 0 described shape circle and the inwall of described annular groove
Offset.
Under the effect of 0 shape circle, formed between upper shell and lower shell and seal reliably, thus effectively guarantee this bin
Job stability.
Alternatively, in the coolant bin of above-mentioned domestic air conditioning, described sealing structure includes being located at
Gask-O-Seal in annular groove, and the both ends of the surface of Gask-O-Seal respectively with lower surface and the end of annular groove of upper shell
Wall offsets.
In the coolant bin of above-mentioned domestic air conditioning, described guide part and lower shell are integral type structure, described
The lateral wall of drain pipe be provided with placing trough in the form of a ring, described sealing ring is positioned at placing trough, and the periphery of sealing ring
Face offsets with the medial wall of described guide part.
Under the effect of placing trough, sealing ring is played preferable position-limiting action, enable sealing ring to move extremely accurately
Specify position and guarantee to be formed between guide part and drain pipe the reliability of sealing, thus improving the work of this bin further
Stability.
In the coolant bin of above-mentioned domestic air conditioning, the lateral wall, upper end of described drain pipe have tapered
Spigot surface, and spigot surface extends to the upper surface of drain pipe.
By arranging spigot surface, in drain pipe is inserted into annular shoulder block, play preferable guide effect, thus further
Reduce the difficulty assembling this bin.
Compared with prior art, the coolant bin of this domestic air conditioning has the advantage that
1, under the effect of guide part, drain pipe is played preferable guide effect, make drain pipe move to accurately refer to
Location is put;Under the effect of annular groove and upper shell lower end, annular shoulder block is made to be in appointment position accurately;Owing to annular is kept off
Shoulder and drain pipe are in elaborate position, the most just enable drain pipe be freely insertable in annular shoulder block, with the completeest
Circularize the assembling of shoulder block and drain pipe.
, between upper shell and lower shell by seal structure formed seal, guide part and drain pipe be by seal
Circle forms sealing, makes can suitably relax machining accuracy and the quality of fit of each parts man-hour in actual adding, thus has
Effect reduces the difficulty assembling this bin.

Detailed description of the invention
The following is specific embodiment of the utility model and combine accompanying drawing, the technical solution of the utility model is made further
Description, but this utility model is not limited to these embodiments.
Embodiment one
As it is shown in figure 1, the coolant bin of this domestic air conditioning is made up of upper shell 1, lower shell 2, drain pipe 3 etc..
Wherein, upper shell 1 and lower shell 2 are all in tubular and both positions are the most right, say, that now, upper shell 1 and under
The central axis conllinear of both cylinders 2.As it is shown in figure 1, have outwardly feed liquor portion 1a on the upper surface of upper shell 1, enter
Liquid portion 1a is in a tubular form and it is coaxial with upper shell 1.The upper surface of lower shell 2 is provided with annular groove, and annular groove and doffing
Body 2 is coaxial.Upper shell 1 is inserted in annular groove, and this lower shell 2 and upper shell 1 fix, and between the two by sealing structure
Formed and seal.In the present embodiment, preferably lower shell 2 and upper shell 1 are fixed together by the way of welding;Natural, top cylinder
Body 1 be bolted on lower shell 2 together with also possible.Seal the ring that structure includes being located on upper shell 1 lateral wall
Shape seal groove and the outer peripheral face of 0 shape circle 4,0 shape circle 4 being located in annular seal groove offset with the inwall of annular groove, so that on
Formed between cylinder 1 and lower shell 2 and seal reliably.
Drain pipe 3 is located in lower shell 2, and lower shell 2 is stretched out in the lower end of this drain pipe 3.As it is shown in figure 1, upper shell 1
There is on medial wall annular shoulder block 1b, annular shoulder block 1b and upper shell 1 is coaxial and both are integral type structure.Annular shoulder block 1b edge
Upper shell 1 axially penetrated through multiple water-guiding hole 1b1, be used for connecting feed liquor portion 1a and lower shell 2.The upper end of drain pipe 3 and ring
Shape shoulder block 1b position is the most right, and the upper end of this drain pipe 3 is through annular shoulder block 1b, and is connected by helicitic texture between the two.Enter
One step explanation, the lateral wall, upper end of drain pipe 3 has tapered spigot surface 3a, and spigot surface 3a extends to drain pipe 3
Upper surface, to improve smoothness when drain pipe 3 and annular shoulder block 1b connection.
As depicted in figs. 1 and 2, the lower surface of lower shell 2 has guide part 2a inwardly projecting and in a tubular form.Guide part
2a and lower shell 2 are integral type structure, and this guide part 2a is enclosed within drain pipe 3 and is formed by sealing ring 5 between the two and seals;
Drain pipe 3 fixes with lower shell 2, and in the present embodiment, preferably drain pipe 3 fixes with lower shell 2 by the way of welding;
Natural, use drain pipe 3 to fix also possible by friction tight mode with lower shell 2.Further illustrate, drain pipe 3
Lateral wall be provided with placing trough in the form of a ring, sealing ring 5 is positioned at placing trough, and the outer peripheral face of sealing ring 5 and guide part 2a
Medial wall offset.
Embodiment two
The present embodiment two is essentially identical with structure and the principle of embodiment one, and different place is: seal structure bag
