Description

Technical Field

[0001] The present application relates to but is not limited to the field of air conditioning technology, and specifically refers to a breathable cap and an air conditioner. Background Art

[0002] Household central air conditioners, especially one-to-many models, not only have many condensation pipes, but also need to be equipped with ventilation caps. The functions of the ventilation caps are as follows:

[0003] 1. The condensate pipe is not only long, but also hidden inside the ceiling. Since users do not want the ceiling to take up too much of the house's floor height, the floor height space left for the slope setting of the condensate pipe is very small. Although it is customary to set the drainage slope of the condensate pipe according to the requirement of 1 / 100, there are also a large number of installation scenarios where the actual drainage slope of the condensate pipe is insufficient. The use of a breathable cap balances the pressure inside and outside the condensate pipe, making the air circulation in the condensate pipe more stable, which can improve the drainage of the condensate pipe.

[0004] 2. During the installation and maintenance of a multi-unit model, it is necessary to use a test drainage method to check the layout quality of the condensate pipe. The installation quality of the condensate pipe can be checked by pouring water into the condensate pipe at the vent cap.

[0005] 3. Dust enters the condensate pipe from the breathable cap, which will cause blockage in the condensate pipe, resulting in poor drainage and water leakage. At this time, the condensate pipe needs to be flushed. Pumping air into the condensate pipe at the breathable cap can be used to blow and clean the condensate pipe to clear the blockage.

[0006] The existing breathable cap is difficult to manufacture and cannot have the above functions at the same time. Utility Model Content

[0025] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0026] The breathable cap provided in the embodiment of the present application is as follows Figures 1 to 5As shown, it includes: a connecting tube, the connecting tube includes a tube body and a support portion 110, the support portion 110 is arranged on the radially outer side of the tube body; and a cap 200, the cap 200 is covered on the first end of the tube body and abuts against the support portion 110, and a first air passage 310 is provided between the cap 200 and the tube body, the first end of the first air passage 310 is connected to the first end of the tube body, and the second end of the first air passage 310 faces the second end of the tube body.

[0027] The support part 110 of the breathable cap is exposed radially outward of the tube body, which makes it easier to manufacture the support part 110, and thus the breathable cap is less difficult to manufacture. The cap 200 is mounted on the first end of the tube body and abuts against the support part 110. A first air passage 310 is provided between the cap 200 and the tube body. The first end of the first air passage 310 is connected to the first end of the tube body, and the second end of the first air passage 310 faces the second end of the tube body. When the breathable cap is mounted on the condensation water pipe, the second end of the connecting pipe faces downward and is connected to the condensation water pipe. The cap 200 is located above the connecting pipe, and the second end of the first air passage 310 faces downward. In this way, dust is not easily discharged from the first air passage 310. The air passage 310 enters the condensate water pipe through the tube body, so the condensate water pipe is less likely to become dirty and clogged to cause problems such as poor drainage and leakage; when the cap 200 is opened, the first end of the tube body is facing upward and exposed to the outside, so that water can be poured into the condensate water pipe from the first end of the tube body to check the installation quality of the condensate water pipe; when the cap 200 is opened, the first end of the tube body is facing upward and exposed to the outside, so that air can be pumped into the condensate water pipe from the first end of the tube body to blow and clean the condensate water pipe to clear the blockage.

[0028] In some examples, such as Figure 1 , Figures 3 to 5 As shown, the tube body includes a main tube section 120 and a tapered section 130, the tapered section 130 is located at the first end of the main tube section 120 and is connected to the main tube section 120, the support portion 110 is arranged on the radially outer side of the tapered section 130, the cap 200 is covered on the end of the tapered section 130 away from the main tube section 120, the first air passage 310 is located between the cap 200 and the tapered section 130, and the second end of the first air passage 310 faces the second end of the main tube section 120; along the axial direction of the main tube section 120: the projection of the cap 200, the projection of the tapered section 130 and the projection of the support portion 110 are all located in the area surrounded by the projection of the outer peripheral surface of the main tube section 120.

[0029] After the second end of the main pipe section 120 is plugged into the condensate pipe and sealed with glue, the insulation sleeve is installed from the upper end of the breathable cap downward. Since the projection of the cover cap 200, the projection of the necked section 130 and the projection of the support portion 110 along the axial direction of the main pipe section 120 are all located in the area surrounded by the projection of the outer circumferential surface of the main pipe section 120, the cover cap 200 and the support portion 110 can pass smoothly through the interior of the insulation sleeve, and finally the insulation sleeve can be tightly covered on the outer circumferential surface of the main pipe section 120. This process is convenient to operate.

[0030] In some embodiments, Figure 1 , Figures 3 to 5 As shown, the support portion 110 includes a support ring and a support rib 111, the support rib 111 is fixedly arranged on the radial outer side of the necking section 130, the support ring is sleeved outside the necking section 130 and fixedly arranged on the support rib 111, and the cap 200 abuts against the support ring. Figure 4 and Figure 5 As shown, there is a second air passage 320 between the support ring and the necking section 130, the second end of the first air passage 310 is connected to the first end of the second air passage 320, and the second end of the second air passage 320 is toward the second end of the main pipe section 120 (that is, the second end of the second air passage 320 is downward), so that dust is not easy to enter the condensate water pipe from the second air passage 320 through the first air passage 310 and the pipe body.

[0031] The support rib 111 is fixedly arranged on the radial outer side of the necking section 130, the support ring is sleeved on the outside of the necking section 130 and fixedly arranged on the support rib 111, the cap 200 is in contact with the support ring, and the cap 200 is supported by the support ring to ensure that the first air passage 310 is formed between the cap 200 and the necking section 130, thereby preventing the necking section 130 from contacting the inner surface of the cap 200 and causing the first air passage 310 to fail to be formed.

[0032] In some embodiments, Figure 1 , Figures 3 to 5 As shown, the support ring includes a main body ring 112 and a positioning ring 113. The main body ring 112 is fixed to the support rib 111, and the positioning ring 113 is arranged on the side of the main body ring 112 facing the cap 200. The cap 200 is sleeved on the positioning ring 113 and abuts against the main body ring 112, so that the cap 200 is less likely to loosen or fall off on the necking section 130. It can be that the cap 200 and the positioning ring 113 are clearance-fitted; or it can be that the cap 200 and the positioning ring 113 are transitionally fit; or it can be that the cap 200 and the positioning ring 113 are interference-fitted, etc. All of the above can achieve the purpose of this application, and its purpose does not deviate from the design concept of the utility model, and will not be repeated here, and all should belong to the protection scope of this application.

[0033] In some embodiments, Figure 1 , Figures 3 to 5 As shown, the support ribs 111 include a plurality of support ribs 111, which are sequentially arranged (e.g., evenly arranged) in the circumferential direction of the necking section 130, so that the main body ring 112 can be more firmly fixed. It can be that the support ribs 111 include two; or it can be that the support ribs 111 include three; or it can be that the support ribs 111 include four, etc.; of course, it can also be that the support rib 111 includes one; all of the above can achieve the purpose of this application, and their purpose does not deviate from the design concept of this utility model, and will not be repeated here, and all should belong to the protection scope of this application.

[0034] In some examples, such as Figure 1 , Figure 2 and Figure 5 As shown, the cap 200 is a conical structure, and an air port 210 is provided on the peripheral wall of the cap 200. The air port 210 is located on the outer side of the tube body in the radial direction of the tube body, and the air port 210 corresponds to the position of the first air channel 310 in the axial direction of the tube body. In this way, the dust falling to the air port 210 under the action of gravity will fall along the first air channel 310 and the second air channel 320 to the bottom of the cap 200, and will not fall into the tube body, and will not fall into the condensation water pipe. Therefore, the condensation water pipe is less likely to be dirty and blocked, resulting in problems such as poor drainage and water leakage.

[0035] In some embodiments, Figure 1 , Figure 2 and Figure 5 As shown, the air port 210 includes a plurality of air ports 210, which are sequentially arranged in the circumference of the cap 200, and each air port 210 extends along the circumference of the cap 200, that is, each air port 210 is an arc-shaped port extending along the circumference of the cap 200, and the arc-shaped port has a longer length and a better ventilation effect. When the height of the installed insulation sleeve is too large, that is, the upper end of the insulation sleeve goes upward over the lower end of the cap 200, the insulation sleeve, the tube body and the lower end of the cap 200 enclose a closed space. At this time, the second end of the second air passage 320 cannot be well connected with the outside air through the closed space, but because the cap 200 is a conical structure, the air port 210 can always maintain a good connection with the outside air, so the air permeable cap of this scheme can better ensure the internal and external pressure balance of the condensate pipe.

[0036] In some examples, the cap 200 and the connecting tube are an integral structure and connected via a flexible connection portion (not shown in the figure). In this way, the breathable cap can be made in one step by injection molding, which not only reduces the assembly cost and the number of molds, but also reduces the procurement cost of materials. After opening the cap 200, the cap 200 will not be lost because it is connected to the connecting tube via the flexible connection portion.

[0037] In some examples, such as Figure 1 and Figure 5As shown, the outer diameter (i.e., diameter) of the second end of the connecting pipe is 25 mm, the inner diameter (i.e., diameter) of the position where the condensate water pipe is connected to the connecting pipe (the opening is facing upward) is 25 mm, and the second end of the connecting pipe is inserted downward into the condensate water pipe (the position where it is connected to the connecting pipe), and the two are sealed by gluing to prevent water leakage at this location.

[0038] In some examples, such as Figure 1 and Figure 5 As shown, the axial height of the cap 200 and the connecting pipe after assembly is no more than 120 mm, so there is basically no need to cut the connecting pipe. After the connecting pipe is installed on the condensate pipe, the upper end of the cap 200 will not abut against the roof.

[0039] Preferably, the axial height of the assembled cap 200 and the connecting pipe is set to about 100 mm, so that the axial height of the air permeable cap can better meet the installation space and the upper end of the cap 200 will not be against the roof.

[0040] The air conditioner (not shown in the figure) provided in the embodiment of the present application includes the breathable cap described in any of the above embodiments.

[0041] This air conditioner has all the advantages of the air permeable cap provided by any of the above embodiments, which will not be described in detail here.

[0042] In summary, in the breathable cap provided in the embodiment of the present application, the support portion is exposed on the radially outer side of the tube body, which makes it easier to manufacture the support portion, and therefore the breathable cap is less difficult to manufacture; the cap is mounted on the first end of the tube body and abuts against the support portion, a first air passage is provided between the cap and the tube body, a first end of the first air passage is communicated with the first end of the tube body, a second end of the first air passage faces the second end of the tube body, when the breathable cap is mounted on the condensation water pipe, the second end of the connecting pipe faces downward and is connected to the condensation water pipe, the cap is located above the connecting pipe, and the first The second end of the air passage faces downward, so that dust is not easy to enter the condensate water pipe from the first air passage through the pipe body. Therefore, the condensate water pipe is less likely to be dirty and blocked to cause problems such as poor drainage and leakage; when the cap is opened, the first end of the pipe body faces upward and is exposed to the outside, so that water can be poured into the condensate water pipe from the first end of the pipe body to check the installation quality of the condensate water pipe; when the cap is opened, the first end of the pipe body faces upward and is exposed to the outside, so that air can be pumped into the condensate water pipe from the first end of the pipe body to blow and clean the condensate water pipe to clear the blockage.
