Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of air conditioner distributors, and particularly relates to an assembled air conditioner distributor. BACKGROUND

[0002] An air conditioner distributor, also known as an air conditioner distributor, is an important component in an air conditioner refrigeration system. The distributor is usually composed of an inlet head, an outlet head and a distribution head. The main function of the distributor is to evenly distribute the refrigerant from the expansion valve to each channel of the evaporator, ensuring that each channel receives an appropriate amount of refrigerant, so that the evaporator can fully and efficiently exchange heat, thereby improving the refrigeration effect of the air conditioning system.

[0003] During the operation of the air conditioning system, dust, debris and impurities that may be carried in the refrigerant in the air are easily accumulated inside the distributor. These impurities gradually block the channels of the distributor, causing poor flow of refrigerant, affecting the refrigeration or heating effect, and even causing some areas to fail to receive normal temperature regulation. The existing technology usually installs a filter screen in the distributor to filter the impurities in the pipe, such as the patent with the publication number CN215638164U. In the process of filtering impurities through the filter screen, if the impurities are evenly distributed on the filter screen, the amount of liquid entering each distribution head through the filter screen is equal, which can ensure uniform distribution of the refrigerant; if the impurities are concentrated in the local position of the filter screen, the amount of liquid entering the corresponding distribution head is reduced, resulting in uneven distribution of the refrigerant in each distribution head. SUMMARY

[0004] The present application aims to solve the technical problems in the prior art by providing an assembled air conditioner distributor.

[0006] As further optimization or improvement of the scheme, the double guide plate is internally provided with a sliding groove, the supporting roller is provided with a sliding block at both ends, the sliding block is in sliding cooperation with the sliding groove, and the sliding rod abuts against the sliding block.

[0007] As further optimization or improvement of the scheme, the liquid outlet head is internally provided with a flow distribution table, and a flow guide strip is mounted on the inner wall of the liquid outlet head.

[0008] As further optimization or improvement of the scheme, a connecting plate is mounted on the sliding rod, and a rotating roller is mounted on the connecting plate.

[0011] As further optimization or improvement of the scheme, the middle box is internally provided with a baffle.

[0012] Advantages of the present application:

[0013] (1) When impurities are concentratedly distributed in a local position of the filter screen, the resistance of the refrigerant passing through the position is increased, at this time, the rotating shaft rotates, when the rotating roller at the bottom of the rotating shaft rolls towards the straight surface direction of the material cavity, the sliding rod moves towards the outer side direction of the double guide plate, under the spring rebounding action, the included angle between the filter screens is increased at this time, the filter screens are unfolded, the passing amount of the refrigerant through the position is increased, the liquid inlet amount of the corresponding liquid distribution head is increased, the liquid inlet amounts of all the liquid distribution heads are effectively balanced, and it is ensured that the refrigerant uniformly enters all the liquid distribution heads.

[0014] (2) With the rotation of the rotating shaft of the present application, the filter screen is in an inclined state, at this time, the space of the material cavity at the bottom of the middle box is released, when the refrigerant passes through the filter screen at the bottom, the refrigerant pushes the impurities on the filter screen to the material cavity direction, so that the impurities enter the material cavity for collection, and since the baffle is mounted on the middle box, the baffle can block the backflow of the impurities to the liquid inlet head.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0029] Referring to Figures 1-11The application discloses an assembled air conditioner distributor which comprises an inlet head 1, an outlet head 2 and a distribution head 3, the input end and the output end of the outlet head 2 are connected with the inlet head 1 and the distribution head 3 respectively, a middle box 5 is arranged on the inlet head 1, and a filter assembly 6 is arranged in the middle box 5; the filter assembly 6 comprises a rotating shaft 601, the rotating shaft 601 is rotatably arranged in the middle box 5, a winding roller 605 is arranged in the rotating shaft 601, and a filter screen 604 is arranged on the winding roller 605; a double guide plate 603 is arranged on the rotating shaft 601, a supporting roller 607 is slidably arranged on the double guide plate 603, a spring 606 is arranged between the supporting rollers 607, and the supporting roller 607 supports the filter screen 604 to make the filter screen 604 in a folded state; a sliding rod 609 is slidably arranged on the top of the double guide plate 603, one end of the sliding rod 609 is connected with a rotating roller 611, and the other end of the sliding rod 609 is connected with the supporting roller 607; a material cavity 10 is arranged in the middle box 5, a straight surface 11 and an arc surface 12 are arranged on the inner wall of the material cavity 10, the rotating roller 611 abuts against the inner wall of the material cavity 10, and the arc surface 12 is concentric with the rotating shaft 601; when the rotating roller 611 rolls towards the arc surface 12 with the rotating of the rotating shaft 601, the position of the sliding rod 609 is unchanged, that is, the included angle between the filter screens 604 is unchanged; when the rotating roller 611 rolls towards the straight surface 11, the sliding rod 609 moves to the outside of the double guide plate 603, and at this time, the included angle between the filter screens 604 is increased.

[0030] Specifically, a sliding groove is formed in the double guide plate 603, sliding blocks 608 are arranged at the two ends of the supporting roller 607, and the sliding blocks 608 are slidably matched with the sliding groove.

[0031] Specifically, a connecting plate 610 is arranged on the sliding rod 609, and the rotating roller 611 is arranged on the connecting plate 610.

[0032] It should be noted that the folding state of the filter screen 604 can be changed by replacing the spring 606 with different specifications to adapt to different use scenarios. The sliding rod 609 is limited by the inner wall of the material cavity 10 through the abutment of the rotating roller 611, so that the spring 606 is in a compressed state.

[0033] It should be noted that the impurities in the refrigerant of the expansion valve are filtered by the filter screen 604 in the middle box 5 during the process that the refrigerant enters the distribution head 3 through the inlet head 1 and the outlet head 2. During the process that the impurities are filtered by the filter screen 604, if the impurities are uniformly distributed on the filter screen 604, that is, the filtered refrigerant can uniformly pass through the outlet head 2 to enter each distribution head 3, in this state, the filter screen 604 does not affect the uniform entry of the refrigerant into the distribution head 3, and therefore the application does not consider this state.

[0034] During the process that the impurities are filtered by the filter screen 604, if the impurities are concentratedly distributed at a local position of the filter screen 604, at this time, the speed of the refrigerant passing through the position is reduced, the liquid agent passing amount of the corresponding distribution head 3 is reduced, and the liquid agent passing amounts of the distribution heads 3 are not the same.

[0035] In use, if the impurities are concentrated in a local position of the filter screen 604, for example, the impurities are concentrated in the lower half of the filter screen 604, the resistance of the refrigerant passing through the position is increased, at this time, the rotating shaft 601 rotates, the process is described with reference to Figures 10-11 The rotating roller 611 at the bottom of the rotating shaft 601 rolls towards the straight surface 11 of the material cavity 10, and the rotating roller 611 at the top of the rotating shaft 601 rolls towards the arc surface 12 of the material cavity 10.

[0036] When the rotating roller 611 at the top of the rotating shaft 601 rolls towards the arc surface 12 of the material cavity 10, since the arc surface 12 is concentric with the rotating shaft 601, the position of the sliding rod 609 in the double guide plate 603 does not change when the rotating roller 611 rolls towards the arc surface 12, that is, the state of the filter screen 604 does not change, and the passing amount of the refrigerant through the position does not change;

[0037] When the rotating roller 611 at the bottom of the rotating shaft 601 rolls towards the straight surface 11 of the material cavity 10, the sliding rod 609 moves towards the outside of the double guide plate 603, and under the rebounding action of the spring 606, the included angle between the filter screens 604 increases at this time, the filter screens 604 are unfolded, the passing amount of the refrigerant through the position increases, and the liquid inlet amount of the corresponding distribution head 3 increases, effectively balancing the liquid inlet amounts of the various distribution heads 3, and ensuring that the refrigerant uniformly enters the various distribution heads 3. Referring to Figure 11 With the rotation of the rotating shaft 601, the filter screen 604 is in an inclined state, at this time, the material cavity 10 at the bottom of the middle box 5 is vacated, and when the refrigerant passes through the filter screen 604 at the bottom, the refrigerant pushes the impurities on the filter screen 604 towards the material cavity 10, so that the impurities enter the material cavity 10 for collection, and since the baffle 9 is installed on the middle box 5, the baffle 9 can block the backflow of the impurities to the liquid inlet head 1.

[0038] Referring to Figure 4 The distribution table 8 is installed inside the liquid outlet head 2, and the flow guide strip 7 is installed on the inner wall of the liquid outlet head 2.

[0039] It should be noted that in the process of the refrigerant entering the distribution head 3 through the liquid inlet head 1 and the liquid outlet head 2, the distribution table 8 distributes the refrigerant inside the liquid outlet head 2, so that the refrigerant uniformly enters the distribution head 3, and the flow guide strip 7 guides the refrigerant, thereby improving the flow efficiency of the refrigerant.

[0040] Referring to Figures 3-7 The liquid inlet head 1 and the liquid outlet head 2 are screw-connected.

[0041] Specifically, the knob 602 is rotationally installed on the middle box 5, and the knob 602 is coaxially connected with the winding roller 605.

[0042] Specifically, the baffle 9 is installed in the middle box 5.

[0043] It should be noted that the arrangement of the baffle 9 does not interfere with the rotation of the filter assembly 6. When maintenance of the distributor is required, the liquid inlet head 1 is detached from the liquid outlet head 2, and then the impurities inside the material cavity 10 are cleaned. If there are impurities remaining on the filter screen 604, the output end of the liquid inlet head 1 is downward, and then the knob 602 is twisted to rotate the winding roller 605 inside the rotating shaft 601, so that the winding roller 605 winds and compresses the spring 606 to fold the filter screen 604, and then the knob 602 is loosened. The spring 606 rebounds to reset the filter screen 604, and the operation is repeated to bounce off the impurities remaining on the filter screen 604 to clean the filter screen 604.

[0044] The implementation principle of the present application is that the filter screen 604 inside the middle box 5 filters the impurities in the refrigerant during the process that the refrigerant of the expansion valve enters the liquid distribution head 3 through the liquid inlet head 1 and the liquid outlet head 2.

[0045] During the process that the filter screen 604 filters the impurities, if the impurities are uniformly distributed on the filter screen 604, that is, the filtered refrigerant can uniformly pass through the liquid outlet head 2 into each liquid distribution head 3, in this state, the filter screen 604 does not affect the uniform entry of the refrigerant into the liquid distribution head 3. Figures 10-11 During the process that the filter screen 604 filters the impurities, if the impurities are concentratedly distributed on the filter screen 604, for example, the impurities are concentratedly distributed on the lower half of the filter screen 604, the resistance of the refrigerant passing through this position increases, at this time, the rotating shaft 601 rotates, and the process is referred to

[0046] When the rotating roller 611 at the top of the rotating shaft 601 rolls towards the arc surface 12 of the material cavity 10, since the arc surface 12 is concentric with the rotating shaft 601, the position of the sliding rod 609 in the double guide plate 603 does not change when the rotating roller 611 rolls towards the arc surface 12, that is, the state of the filter screen 604 does not change, and the passing amount of the refrigerant through this position does not change.

[0047] When the rotating roller 611 at the bottom of the rotating shaft 601 rolls towards the straight surface 11 of the material cavity 10, the sliding rod 609 moves towards the outside of the double guide plate 603, and under the rebounding action of the spring 606, the included angle between the filter screens 604 increases at this time, the filter screens 604 are unfolded, the passing amount of the refrigerant through this position increases, and the liquid inlet amount of the corresponding liquid distribution head 3 also increases, effectively balancing the liquid inlet amounts of each liquid distribution head 3 to ensure that the refrigerant uniformly enters each liquid distribution head 3.

[0048] Referring to Figure 11When the shaft 601 rotates, the filter screen 604 is in an inclined state, at this time, the space of the material cavity 10 at the bottom of the middle box 5 is released, when the refrigerant passes through the filter screen 604 at the bottom, the impurities on the filter screen 604 are pushed to the material cavity 10 direction by the refrigerant, so that the impurities enter the material cavity 10 to collect, since the baffle 9 is installed on the middle box 5, the baffle 9 can block the backflow of the impurities to the liquid inlet head 1.

[0049] When the distributor needs to be maintained, the liquid inlet head 1 is detached from the liquid outlet head 2, then the impurities inside the material cavity 10 are cleaned. If the filter screen 604 has residual impurities, the output end of the liquid inlet head 1 is downward, then the knob 602 is twisted, the knob 602 drives the roller 605 inside the shaft 601 to rotate, the roller 605 winds and compresses the spring 606 to make the filter screen 604 fold, then the knob 602 is loosened, the spring 606 rebounds to drive the filter screen 604 to reset, the residual impurities on the filter screen 604 are bounced off, the cleaning of the filter screen 604 is realized.

[0050] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, the above embodiments and the description in the specification are only to illustrate the principle of the present application, various changes and improvements can be made without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the present application.
