Description

Technical Field

[0001] This application belongs to the technical field of air conditioning, and particularly relates to a silencer valve, an outdoor unit of an air conditioner, and an air conditioner. Background Technology

[0002] Air conditioners can be installed in indoor or outdoor environments and provide cooling or heating. In patent application number CN2020221714479, a silencer structure based on a four-way valve and an air conditioning system using the same are disclosed. The silencer valve is an important component of the air conditioning system. Its main function is to switch the flow of refrigerant between cooling and heating. At the same time, as a cavity structure, the silencer valve also has a certain noise reduction performance. However, the existing silencer valves have low noise reduction performance, which greatly limits their use. Summary of the Invention

[0003] This application aims to at least partially solve the technical problem of the low noise reduction performance of current silencers. To this end, this application provides a silencer, an outdoor air conditioning unit, and an air conditioner.

[0004] In a first aspect, an embodiment of this application provides a silencer valve, comprising:

[0005] The housing has an inner cavity and at least two communication ports communicating with the inner cavity; a flow channel is formed between the two communication ports and the inner cavity;

[0006] A movable seat is installed in the inner cavity;

[0007] A baffle is installed on the movable seat and is sealed to the inner wall of the inner cavity; the baffle, the movable seat and the inner wall of the inner cavity enclose a resonant cavity; the baffle is provided with a through hole, which connects the resonant cavity and the flow channel.

[0008] In the silencer valve proposed in this application embodiment, the resonant cavity is formed by the enclosure between the baffle, the movable seat and the inner sidewall of the inner cavity, and the inner cavity is separated by the baffle, making full use of a part of the space of the inner cavity and a part of the space of the movable seat. The resonant cavity is connected to the flow channel through the through hole, and cancels the frequency corresponding to the noise in the flow channel, and performs noise reduction, thereby improving the noise reduction effect and noise reduction performance of the silencer valve.

[0009] In some embodiments, the baffle divides the inner cavity into a plurality of cavities, the plurality of cavities including at least one of the resonant cavities.

[0010] The resonant cavity cancels out the frequency corresponding to the noise in the flow channel and performs noise reduction, thereby improving the noise reduction effect and noise reduction performance of the silencer valve.

[0011] In some embodiments, the resonant cavity is arranged adjacent to the flow channel, and the resonant cavity is connected to the flow channel through the through hole.

[0012] This reduces the distance between the resonant cavity and the flow channel, decreases the thickness of the baffle, and improves the noise reduction effect and noise reduction performance of the resonant cavity on the flow channel.

[0013] In some embodiments, the movable seat is provided with a groove and a first through hole; the groove communicates with the resonant cavity through the first through hole.

[0014] The groove connects to the resonant cavity through the first through hole and increases the volume of the resonant cavity to improve the noise reduction and sound attenuation effect of the resonant cavity.

[0015] In some embodiments, the housing further includes a communication port; the movable base is movably mounted in the inner cavity;

[0016] When the movable seat moves within the inner cavity, the baffle moves along with the inner cavity and adjusts the connection between the three connecting ports to form a first sub-channel and a second sub-channel.

[0017] The first sub-channel and the second sub-channel are selectively connected to the resonant cavity.

[0018] In some embodiments, the first sub-channel and the second sub-channel are respectively a cooling channel and a heating channel.

[0019] In some embodiments, the three connecting ports are arranged sequentially along the length of the housing; the connecting port in the middle forms the first sub-channel and the second sub-channel with the other two connecting ports respectively;

[0020] The baffle is disposed on one side of the central connection port and moves to the other side of the connection port as the movable seat slides within the cavity, thereby allowing the resonant cavity to selectively connect to either the first sub-channel or the second sub-channel.

[0021] This allows the resonant cavity to provide corresponding noise reduction for the first or second sub-channel at different positions of the movable seat, so that the resonant cavity can reduce noise for the first or second sub-channel within the silencer valve without affecting the operation of the first or second sub-channel.

[0022] In some embodiments, the baffle is located in the middle of the movable seat.

[0023] This allows the baffles to evenly divide the inner cavity and form a spatially consistent resonant cavity.

[0024] In some embodiments, the silencer valve further includes a first sealing element, which is installed between the inner wall of the inner cavity and the outer peripheral wall of the movable seat, and seals the inner wall of the inner cavity and the outer peripheral wall of the movable seat.

[0025] This improves the sealing effect between the inner wall of the inner cavity and the outer peripheral wall of the movable seat, ensuring that the resonant cavity has only one through hole for external communication.

[0026] In some embodiments, the silencer valve further includes a second seal, which is installed between the inner wall of the inner cavity and the outer peripheral wall of the baffle, and seals the inner wall of the inner cavity and the outer peripheral wall of the baffle.

[0027] This improves the sealing effect between the inner wall of the cavity and the outer peripheral wall of the baffle, ensuring that the resonant cavity has only one through hole for external communication.

[0028] In some embodiments, the second seal and the first seal are an integral structure and are elastic.

[0029] Secondly, based on the silencer valve mentioned above, this application also proposes an outdoor air conditioning unit that includes the aforementioned silencer valve.

[0030] Thirdly, based on the air conditioner outdoor unit described above, this application also proposes an air conditioner that includes the aforementioned air conditioner outdoor unit. Attached Figure Description

[0049] This application is described below with reference to the accompanying drawings and specific embodiments:

[0050] Example 1

[0051] Please refer to Figures 1 to 7 This application discloses a silencer valve, including a housing 100, a movable base 200, and a baffle 300. The silencer valve can be applied to electrical equipment such as air conditioners, dehumidifiers, and fresh air systems. The above are merely preferred embodiments of the present invention and are not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0052] The housing 100 serves as a support component for the silencer valve, supporting the movable seat 200 and the baffle 300. The housing 100 has an inner cavity 110 and at least two connecting ports 120 communicating with the inner cavity 110; a flow channel 130 is formed between the two connecting ports 120 and the inner cavity 110. This flow channel 130 can be a cooling flow channel or a heating flow channel. The above is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0053] In some embodiments, the housing 100 is further provided with a communication port 120. In this case, the housing 100 may have three communication ports 120, which are arranged sequentially along the length of the housing 100. The middle communication port 120 forms a first sub-channel 131 and a second sub-channel 132 with the other two communication ports 120, wherein the first sub-channel 131 and the second sub-channel 132 are respectively a cooling channel and a heating channel, and the first sub-channel 131 or the second sub-channel 132 is formed according to the position of the baffle 300.

[0054] In some embodiments, the housing 100 may have four ports 120, and the silencer valve may be a four-way valve.

[0055] The movable seat 200 is installed in the inner cavity 110 and moves within the inner cavity 110. At this time, the movable seat 200 is movably installed in the inner cavity 110 and sleeved within the inner cavity 110.

[0056] The baffle 300 is installed on the movable seat 200 and its position is adjusted as the movable seat 200 moves. When the movable seat 200 moves within the inner cavity 110, the baffle 300 moves with the inner cavity 110 and adjusts the connection between the three connecting ports 120 to form the first sub-channel 131 and the second sub-channel 132.

[0057] In some embodiments, when the movable seat 200 moves to the left, the baffle 300 is disposed to the left of the middle connecting port 120, and the middle connecting port 120, the inner cavity 110 and the right connecting port 120 form a first sub-flow channel 131, which serves as a cooling flow channel.

[0058] In some embodiments, when the movable seat 200 moves to the right, the baffle 300 is disposed on the right side of the middle connecting port 120, the middle connecting port 120, the inner cavity 110 and the left connecting port 120 form a second sub-flow channel 132, which serves as a heating flow channel.

[0059] The baffle 300 is located in the middle of the movable seat 200 and is disposed on one side of the central connecting port 120, so that the baffle 300 can evenly divide the inner cavity 110 and form a spatially consistent resonant cavity 310.

[0060] The baffle 300 is sealed to the inner wall of the inner cavity 110; the baffle 300, the movable seat 200, and the inner wall of the inner cavity 110 enclose a resonant cavity 310. The baffle 300 is provided with a through hole 320, which connects the resonant cavity 310 and the flow channel 130. In this embodiment, the diameter of the through hole 320 is 0.5 mm. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0061] The baffle 300 is located on one side of the central connecting port 120 and moves to the other side of the connecting port 120 as the movable seat 200 slides in the inner cavity 110. This allows the resonant cavity 310 to selectively connect to the first sub-channel 131 or the second sub-channel 132, so that the resonant cavity 310 can provide corresponding noise reduction to the first sub-channel 131 or the second sub-channel 132 at different positions of the movable seat 200. This allows the resonant cavity 310 to reduce noise in the first sub-channel 131 or the second sub-channel 132 within the silencer valve without affecting the operation of the first sub-channel 131 or the second sub-channel 132. The baffle 300 is located in the middle of the movable seat 200, so the resonant cavity 310 occupies nearly half of the space of the four-way valve cavity, achieving a significant noise reduction effect. The through hole 320 connects the resonant cavity 310 and the flow channel 130. The wavelength of sound equals the wave speed / frequency. The wave speed of sound is generally 340 meters per second, and the frequency of sound heard by the human ear is 20 Hz to 20 kHz. Therefore, the wavelength of the noise of flowing refrigerant that the human ear can hear is 0.017 meters to 17 meters, or 1.7 cm to 1700 cm. When the depth and diameter of the through hole 320 are much smaller than the wavelength of the sound wave, for example, in this embodiment, the diameter of the through hole 320 is 0.5 mm, which is much smaller than 1.7 cm to 1700 cm. The air column in the hole acts like a mass block, while the volume of the resonant cavity 310 is much larger than that of the through hole 320, acting like an air spring. Thus, a "resonance system - spring-mass block system" can be formed. When the frequency of the incident sound wave is equal to the natural frequency of the system, the air column in the 320mm aperture vibrates violently due to resonance and rubs against the hole wall, thereby consuming sound energy and reducing the noise of the refrigerant flowing through the channel.

[0062] The resonant cavity 310 is arranged adjacent to the flow channel 130. The resonant cavity 310 is connected to the flow channel 120 through a through hole 320, which reduces the distance between the resonant cavity 310 and the flow channel 130, reduces the thickness of the baffle 300, and improves the noise reduction effect and noise reduction performance of the resonant cavity 310 on the flow channel 130. The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0063] In the silencer valve proposed in this application embodiment, the resonant cavity 310 is formed by the enclosure between the baffle 300, the movable seat 200, and the inner wall of the inner cavity 110. The baffle 300 divides the inner cavity 110, making full use of a portion of the space in the inner cavity 110 and a portion of the space in the movable seat 200. The resonant cavity 310 is connected to the flow channel 130 through a through hole 320, canceling the frequencies corresponding to noise in the flow channel 130 and silencing it, thereby improving the noise reduction effect and performance of the silencer valve. This silencer valve with a resonant cavity 310 and a through hole 320 can replace a conventional silencer while acting as a standard four-way valve in an air conditioning system, integrating the silencer function into the four-way valve to eliminate the need for a separate silencer, thus reducing costs and minimizing the space occupied inside the air conditioner. The above are merely preferred embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this invention shall be included within the scope of protection of this invention.

[0064] Please refer to Figure 2 In some embodiments, when the movable seat 200 moves to the left, the resonant cavity 310 is located on the left side of the first sub-channel 131 and is connected to the first sub-channel 131 through the through hole 320. At this time, the resonant cavity 310 performs noise reduction treatment on the first sub-channel 131, cancels the frequency corresponding to the noise in the first sub-channel 131, and performs noise reduction, thereby improving the noise reduction effect and noise reduction performance of the silencer valve. The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0065] Please refer to Figure 3 In some embodiments, when the movable seat 200 moves to the right, the resonant cavity 310 is located on the right side of the second sub-channel 132 and is connected to the second sub-channel 132 through the through hole 320. At this time, the resonant cavity 310 performs noise reduction treatment on the second sub-channel 132, cancels the frequency corresponding to the noise in the second sub-channel 132, and performs noise reduction, thereby improving the noise reduction effect and noise reduction performance of the silencer valve. The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0066] Specifically, the resonant cavity 310 references the noise reduction principle of a Helmholtz resonant cavity, and the frequency output by the resonant cavity 310 is adjusted by the cross-sectional area of ​​the through hole 320, the aperture of the through hole 320, or the volume of the resonant cavity 310. Optionally, the frequency output by the resonant cavity 310 can be adjusted to the frequency corresponding to the noise in the first sub-channel 131 or the second sub-channel 132. The frequency corresponding to the noise in the first sub-channel 131 or the second sub-channel 132 can be pre-acquired, and customized design can be performed based on the acquired frequency to improve the noise reduction effect of the resonant cavity 310. It is applicable to both the first sub-channel 131 and the second sub-channel 132. Optionally, the frequency corresponding to the noise in the first sub-channel 131 and the frequency corresponding to the noise in the second sub-channel 132 are close. The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this invention shall be included within the scope of protection of this invention.

[0067] Specifically, the calculation of the silencing frequency in the silencing principle of a Helmholtz resonator:

[0068]

[0069] f r : Resonant frequency (i.e., the center frequency of silencing); C r : Velocity of sound of refrigerant; S: Cross-sectional area of ​​through hole; l k V: Effective length of the through-hole; V: Volume of the resonant cavity. It can be seen that by changing one or more parameters among the refrigerant sound velocity, the cross-sectional area of ​​the through-hole 320, the effective length of the through-hole 320, and the volume of the resonant cavity 310, the resonant frequency of the resonant cavity 310 can be adjusted, thereby adjusting the resonant frequency of the resonant cavity 310. This corresponds to the frequencies of noise in multiple different flow channels, achieving cancellation of the frequencies of noise in different flow channels, thus improving the noise reduction effect and noise reduction performance of the silencer valve. The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0070] Therefore, the first sub-channel 131 and the second sub-channel 132 are selectively connected to the resonant cavity 310, and the resonant cavity 310 can reduce noise in the cooling or heating channel, improving the application of the silencer valve in cooling and heating pipes. The above is merely a preferred embodiment of the present invention and is not intended to limit the invention.

[0073] In some embodiments, the baffle 300 divides the inner cavity 110 into a plurality of cavities 111, each cavity 111 including at least one resonant cavity 310. Optionally, there may be two, four, or six resonant cavities 310, which can be adjusted according to actual conditions. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention.

[0075] In some embodiments, the movable base 200 is provided with a groove 210 and a first through hole 220; the groove 210 connects to the resonant cavity 310 through the first through hole 220. In this case, the groove 210 connects to the resonant cavity 310 through the first through hole 220, and increases the volume of the resonant cavity 310, so as to improve the noise reduction and sound attenuation effect of the resonant cavity 310. The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations.
