Description

Technical Field

[0001] The invention belongs to the technical field of air-conditioning distributors, and in particular relates to an assembled air-conditioning distributor. Background Art

[0002] The air conditioner distributor, also known as the air conditioner liquid distributor, is an important component in the air conditioning refrigeration system. The distributor is usually composed of a liquid inlet head, a liquid outlet head and a liquid distributor 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 can get the right amount of refrigerant, so that the evaporator can fully and efficiently perform heat exchange, thereby improving the refrigeration effect of the air conditioning system.

[0003] During the operation of the air conditioning system, dust and debris in the air, as well as impurities that may be carried in the refrigerant, are likely to accumulate inside the distributor. These impurities will gradually block the channel of the distributor, causing poor flow of the refrigerant, affecting the cooling or heating effect, and even causing some areas to be unable to obtain normal temperature regulation. The prior art usually installs a filter in the distributor to filter impurities in the tube, such as the patent with announcement number CN215638164U. In the process of filtering impurities through the filter, if the impurities are evenly distributed on the filter, the amount of liquid entering each liquid distribution head through the filter is equal, which can ensure uniform distribution of the refrigerant; if the impurities are concentrated in a local position of the filter, the amount of liquid inlet to the corresponding liquid distribution head is reduced, resulting in uneven distribution of refrigerant in each liquid distribution head. Summary of the invention

[0004] The purpose of the present invention is to provide an assembled air conditioning distributor to solve the technical problems in the prior art in view of the deficiencies in the prior art.

[0005] The purpose of the present invention can be achieved by the following technical scheme: an assembled air conditioner distributor, which includes a liquid inlet head, a liquid outlet head and a liquid separation head, wherein the input end and the output end of the liquid outlet head are respectively connected to the liquid inlet head and the liquid separation head, a central box is installed on the liquid inlet head, and a filter assembly is installed in the central box; the filter assembly includes a rotating shaft, a rotating shaft is rotatably installed in the central box, a roller is installed in the rotating shaft, and a filter screen is installed on the roller; a double guide plate is installed on the rotating shaft, a support roller is slidably installed on the double guide plate, a spring is installed between the support rollers, and the support rollers are installed. The filter is propped up to make it folded; a slide rod is slidably installed on the top of the double guide plate, one end of the slide rod is connected to the roller, and the other end of the slide rod is connected to the support roller; a material cavity is arranged in the middle box, and the inner wall of the material cavity is provided with a straight surface and a curved surface, the roller abuts against the inner wall of the material cavity, and the curved surface is concentric with the rotating shaft; as the rotating shaft rotates, when the roller rolls toward the curved surface, the position of the slide rod remains unchanged, that is, the angle between the filter screens remains unchanged; if the roller rolls toward the straight surface, the slide rod moves toward the outer side of the double guide plate, and the angle between the filter screens increases.

[0006] As a further optimization or improvement of this solution, a chute is provided inside the double guide plate. Sliders are installed at both ends of the support roller, and the sliders are slidably engaged with the chute, and the sliding rod abuts against the slider.

[0007] As a further optimization or improvement of this solution, a flow splitting table is installed inside the liquid outlet head, and flow guiding strips are installed on the inner wall of the liquid outlet head.

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

[0009] As a further optimization or improvement of this solution, the liquid inlet head and the liquid outlet head are threadedly connected.

[0010] As a further optimization or improvement of this solution, a knob is rotatably installed on the middle box, and the knob is coaxially connected to the winding roller.

[0011] As a further optimization or improvement of this solution, a baffle is installed inside the middle box.

[0012] Advantages of the present invention:

[0013] (1) When the present invention is in use, if impurities are concentrated in a local position of the filter screen, the resistance of the refrigerant passing through this position increases. 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 of the double guide plate. Under the action of the spring rebound, the included angle between the filter screens increases at this time, the filter screens unfold, the passing amount of the refrigerant passing through this position increases, and the liquid inlet amount of the corresponding liquid distribution head increases accordingly, effectively balancing the liquid inlet amounts of each liquid distribution head and ensuring that the refrigerant enters each liquid distribution head evenly.

[0014] (2) As the rotating shaft of the present invention rotates, the filter screen is in an inclined state. At this time, space is vacated in the material cavity at the bottom of the middle box. When the refrigerant passes through the filter screen at the bottom, the refrigerant pushes the impurities on the filter screen towards the material cavity, so that the impurities enter the material cavity for collection. Since a baffle is installed on the middle box, the baffle can block the impurities from flowing back to the liquid inlet head. Description of the drawings

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] See Figures 1 - 11, An assembled air conditioner distributor, which includes a liquid inlet head 1, a liquid outlet head 2 and a liquid distribution head 3. The input end and the output end of the liquid outlet head 2 are respectively connected to the liquid inlet head 1 and the liquid distribution head 3. A middle box 5 is installed on the liquid inlet head 1, and a filtering component 6 is installed in the middle box 5; the filtering component 6 includes a rotating shaft 601, the rotating shaft 601 is rotatably installed in the middle box 5, a winding roller 605 is installed in the rotating shaft 601, and a filter screen 604 is installed on the winding roller 605; a double guide plate 603 is installed on the rotating shaft 601, a support roller 607 is slidably installed on the double guide plate 603, a spring 606 is installed between the support rollers 607, and the support rollers 607 support the filter screen 604 to make the filter screen 604 in a folded shape; a sliding rod 609 is slidably installed at the top of the double guide plate 603, one end of the sliding rod 609 is connected to a rotating roller 611, and the other end of the sliding rod 609 is connected to the support roller 607; a material cavity 10 is arranged in the middle box 5, a straight surface 11 and a curved 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 curved surface 12 is concentric with the rotating shaft 601; as the rotating shaft 601 rotates, when the rotating roller 611 rolls towards the curved surface 12, the position of the sliding rod 609 remains unchanged, that is, the included angle between the filter screens 604 remains unchanged; if the rotating roller 611 rolls towards the straight surface 11, the sliding rod 609 moves towards the outer side of the double guide plate 603, and at this time the included angle between the filter screens 604 increases.

[0030] Specifically, a chute is opened in the double guide plate 603, sliding blocks 608 are installed at both ends of the support roller 607, and the sliding blocks 608 are slidably matched with the chute, and the sliding rod 609 abuts against the sliding blocks 608.

[0031] Specifically, a connecting plate 610 is installed on the sliding rod 609, and a rotating roller 611 is installed 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 specification of the spring 606 to adapt to different use scenarios. The sliding rod 609 abuts against the inner wall of the material cavity 10 through the rotating roller 611 to limit the support roller 607, so that the spring 606 is in a compressed state.

[0033] It should be noted that 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, the filter screen 604 inside the middle box 5 filters the impurities in the refrigerant. During the process of the filter screen 604 filtering the impurities, if the impurities are evenly distributed on the filter screen 604, that is, the filtered refrigerant can evenly enter each liquid distribution head 3 through the liquid outlet head 2. In this state, the filter screen 604 does not affect the uniform entry of the refrigerant into the liquid distribution head 3, so this state is not considered in the present invention.

[0034] During the process of the filter screen 604 filtering the impurities, 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 this position decreases, and the liquid agent passing amount of the corresponding liquid distribution head 3 decreases, resulting in different liquid agent passing amounts of each liquid distribution head 3.

[0035] When the present invention is in use, if 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 this position increases. At this time, the rotating shaft 601 rotates. This process refers to Figures 10 - 11 , the roller 611 at the bottom of the rotating shaft 601 rolls towards the straight surface 11 of the material chamber 10, and the roller 611 at the top of the rotating shaft 601 rolls towards the arc surface 12 of the material chamber 10.

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

[0037] When the roller 611 at the bottom of the rotating shaft 601 rolls towards the straight surface 11 of the material chamber 10, the slide bar 609 moves towards the outside of the double guide plate 603. Under the action of the spring 606 rebounding, at this time, the included angle between the filter screens 604 increases, the filter screens 604 unfold, the passing amount of the refrigerant passing through this position increases, and the liquid inlet amount of the corresponding liquid distribution head 3 increases accordingly, effectively balancing the liquid inlet amounts of each liquid distribution head 3 and ensuring that the refrigerant enters each liquid distribution head 3 evenly. See Figure 11 , as the rotating shaft 601 rotates, the filter screen 604 is in an inclined state. At this time, the material chamber 10 at the bottom of the middle box 5 vacates space. 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 chamber 10, causing the impurities to enter the material chamber 10 for collection. Since the baffle 9 is installed on the middle box 5, the baffle 9 can block the impurities from flowing back to the liquid inlet head 1.

[0038] See Figure 4 , a flow dividing table 8 is installed inside the liquid outlet head 2, and a guide strip 7 is installed on the inner wall of the liquid outlet head 2.

[0039] It should be noted that during the process of the refrigerant entering the liquid distribution head 3 through the liquid inlet head 1 and the liquid outlet head 2, the flow dividing table 8 divides the refrigerant inside the liquid outlet head 2 to make it enter the liquid distribution head 3 evenly. At the same time, the guide strip 7 guides the refrigerant to improve the flow efficiency of the refrigerant.

[0040] See Figures 3 - 7 , the liquid inlet head 1 and the liquid outlet head 2 are threadedly connected.

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

[0042] Specifically, a baffle 9 is installed inside 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 the dispenser needs to be maintained, the liquid inlet head 1 is removed from the liquid outlet head 2, and then the impurities inside the material chamber 10 are cleaned. If there are impurities remaining on the filter screen 604, the output end of the liquid inlet head 1 is turned downward, and then the knob 602 is rotated. The knob 602 drives the roller 605 inside the rotating shaft 601 to rotate, so that the roller 605 winds up and compresses the spring 606 of the filter screen 604, causing the filter screen 604 to fold up. Then the knob 602 is released, and the spring 606 rebounds to drive the filter screen 604 to reset. By repeating the operation, the impurities remaining on the filter screen 604 are bounced off, realizing the cleaning of the filter screen 604.

[0044] The implementation principle of the present invention is as follows: When the refrigerant of the expansion valve enters the liquid distribution head 3 through the liquid inlet head 1 and the liquid outlet head 2, the filter screen 604 inside the middle box 5 filters the impurities in the refrigerant. During the process of the filter screen 604 filtering impurities, if the impurities are evenly distributed on the filter screen 604, that is, the filtered refrigerant can evenly enter each liquid distribution head 3 through the liquid outlet head 2. In this state, the filter screen 604 has no influence on the uniform entry of the refrigerant into the liquid distribution heads 3.

[0045] During the process of the filter screen 604 filtering impurities, if the impurities are concentratedly distributed at a local position of the filter screen 604, for example, the impurities are concentrated in the lower half part of the filter screen 604, the resistance of the refrigerant passing through this position increases. At this time, the rotating shaft 601 rotates. This process refers to Figures 10 - 11 , the roller 611 at the bottom of the rotating shaft 601 rolls towards the straight surface 11 of the material chamber 10, and the roller 611 at the top of the rotating shaft 601 rolls towards the arc surface 12 of the material chamber 10.

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

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

[0048] See Figure 11, as the rotating shaft 601 rotates, the filter screen 604 is in an inclined state. At this time, the material chamber 10 at the bottom of the middle box 5 vacates space. 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 chamber 10, causing the impurities to enter the material chamber 10 for collection. Since the baffle 9 is installed on the middle box 5, the baffle 9 can block the impurities from flowing back to the liquid inlet head 1.

[0049] When maintenance of the dispenser is required, the liquid inlet head 1 is removed from the liquid outlet head 2, and then the impurities inside the material chamber 10 are cleaned. If there are impurities remaining on the filter screen 604, the output end of the liquid inlet head 1 is oriented downward, and then the knob 602 is rotated. The knob 602 drives the roller 605 inside the rotating shaft 601 to rotate, causing the roller 605 to wind up the filter screen 604 and compress the spring 606, folding the filter screen 604. Then the knob 602 is released, and the spring 606 rebounds to drive the filter screen 604 to reset. By repeating the operation, the impurities remaining on the filter screen 604 are bounced off, realizing the cleaning of the filter screen 604.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
