Abstract

The utility model relates to a domestic air conditioner liquid storage device. The bottom of the utility model is provided with a liquid outlet which is provided with a flanging, a liquid outlet pipe is divided into an inner iron pipe and an outer copper pipe, and the ends of the two pipes are respectively made into corresponding shapes by a flaring or a necking process method and are respectively welded on the flanging of the liquid outlet; thereby, the utility model has the characteristics of simple assembly, good product manufacturing quality, manufacturing cost of the product reducing, etc.

Description

The domestic air conditioning reservoir

The utility model relates to the temporary transient container that stores of liquid refrigerant of a kind of container of storaging liquid, particularly domestic air-conditioning system.

There is the air-conditioning system reservoir in existing traditional family, see shown in attached Fig. 1 and 2, its structure is formed: be provided with liquid outlet 12 in the bottom of body 11, on it by being welded with copper pipe 13 after the mechanical fixation, this copper pipe has promptly formed the cold-producing medium flow pass of reservoir, and this flow pass is divided into straight type and bent pipe two parts, and it is linked together by welding and body bottom liquid outlet.And straight type copper pipe is owing to the inside at body 11, it does not contact with extraneous air, thereby be difficult for getting rusty, adopt copper pipe in this section unlike adopting iron pipe what advantage is arranged, and copper is 5: 1 with the price ratio of iron under equal volume, thereby this part selects for use the obvious manufacturing cost of copper pipe higher in fact.

And in the reservoir of above-mentioned traditional structure, because one section bend pipe outside following body must more accurate location, and copper pipe itself is not used to the structure of locating, thereby causes the assembling difficulty.Figure must carry out fixing with respect to body to this copper pipe, must carry out in the mechanical fixation itself and body connection place.In addition in carrying out machining and manufacture process, can take place the harmful fine-powder of kind of refrigeration cycle residually, influence the refrigeration work effect.

In addition, in the reservoir of aforementioned conventional, because body and copper pipe connection place, body are the thicker structures of whole wall thickness, copper pipe then is the thin structure of whole wall thickness, difference because of body and copper pipe material, cause both significantly different, have the setting difficulty of welding condition in the thermal capacity of welding portion.Be that mechanical fixation need be carried out in body and copper pipe connection place again, cause the welding portion shape not ideal enough, and because of the acting in conjunction of above-mentioned factor, it is of low quality to cause welding to be regardless of, and influences result of use.

The purpose of this utility model is in order to overcome the deficiency of above-mentioned existence, and a kind of domestic air conditioner reservoir that is fixed with drain pipe at the liquid outlet place that simple, low cost of manufacture, quality obviously improve of assembling is provided.

The purpose of this utility model is finished by following technical solution, it mainly includes the body of a liquid storage, bottom at body offers liquid outlet, wherein be fixed with drain pipe, described liquid outlet is provided with the tubulose flange, and iron pipe and outer copper pipe also welded respectively on the tubulose flange of body bottom liquid outlet in drain pipe was divided into.

Flange described in the utility model is one section upwards straight tube-like, and interior iron pipe and outer copper pipe match to weld through enlarging or reducing or original shape respectively and be formed on the flange of straight tube-like.

Iron pipe is handled with enlarging and is formed step in described, and is enclosed within on the flange of straight tube-like, and outer copper pipe is inserted in the flange with prototype, and its end is connected to stage portion and welds separately and is connected.

Description of drawings is as follows:

Fig. 1 is the structural representation of former reservoir.

Fig. 2 is the partial structurtes enlarged diagram at Figure 1A place.

Fig. 3 is a structural representation of the present utility model.

Fig. 4 is the partial structurtes enlarged diagram at Fig. 3 B place.

Fig. 5-Figure 22 is the partial structurtes enlarged diagram of other embodiment at Fig. 3 B place.

To be described in detail the utility model by accompanying drawing below: it mainly comprises reservoir body 21 Fig. 1-Fig. 4, be provided with the cold-producing medium flow pass in the bottom of body 21, the bottom that it is included in body 21 is provided with liquid outlet 22 and the drain pipe that is connected on the liquid outlet, and drain pipe be divided in iron pipe 23 and outer copper pipe 24, in promptly weldering is shaped on liquid outlet 22 iron pipe 23 with outside copper pipe 24.At first liquid outlet 22 is provided with the vertical tubular flange 25 that upwards extends along central axis, the pipe link of interior iron pipe 23 is handled back formation step 26 backs by enlarging to be nested with at flange 25 in body 21, welding is connected then, link with outer copper pipe 24 is inserted in the flange 25 again, and its end presses closer in step 26 bottoms of interior iron pipe 23 and welding is connected, because this time the more preceding welding temperature of welding is low, and a preceding weld seam is after the hyperthermic treatment second time, scolder distributes more even, and under flange 25 positioning actions, the welding location of the drain pipe that iron pipe 23 and outer copper pipe 24 are formed in making is more accurate, has solved the eccentricity issues of drain pipe simultaneously.

Fig. 5-Figure 22 is respectively the structural representation that interior iron pipe 33 of other embodiment and outer copper pipe 34 system of welding on body 31 bottom liquid outlets 32 are connected, various difform flange 35 are wherein arranged, and the position relation that is fixedly connected with between the interior iron pipe 33 shown in the figure, outer copper pipe 34 and the flange 35 is represented by each figure.

The utility model is compared with traditional reservoir, has assembling simply, and the manufacturing cost of product reduces, can Make the raising of welding quality and operation, copper pipe is solved with respect to the eccentricity issues of body, can be effective Reduction is to the content of fine-powder harmful in the kind of refrigeration cycle, thereby makes quality, the serviceability of product have bigger The characteristics such as the raising of degree.
