Description
Technical Field
[0001] This invention relates to the field of air conditioning technology, and in particular to an air conditioner and its duct unit. Background Technology
[0002] Ductless air conditioners are primarily installed by ceiling mounting. With the rapid development of modern society, interior layouts in real estate are constantly evolving, resulting in a wide variety of layout options. However, most existing ductless air conditioners in the industry feature single-sided duct outlets. After-sales installation requires extending the ductwork and manually bending the pipes to change the outlet direction, which is detrimental to the overall performance and duct reliability, increases after-sales installation costs, makes air conditioning installation more difficult, and poses risks of pipe leaks and breaks.
[0003] Existing indoor units that can be connected to both sides are manufactured with the pipes exiting from the right side by default, and the support is installed on the lower layer of the pipes. If after-sales service requires the pipes to exit from the left side, the support must be removed first, and the pipes must be manually bent so that the pipe outlet faces the left. The pipe reversal process is cumbersome and carries the risk of pipe leakage. This can lead to refrigerant leakage during unit use, and there is also the risk of pipe breakage. Once the pipe breaks, after-sales service is very troublesome, resulting in a very poor user experience and affecting the brand's reputation and influence. Summary of the Invention
[0004] To address the technical problems of existing technologies that require lengthening connecting pipes and forcibly bending pipes to change the direction of the outlet pipe, this invention provides an air conditioner and its duct unit.
[0005] The present invention adopts the following technical solution.
[0006] A first aspect of the present invention provides a ducted air conditioner, including an evaporator component, the evaporator component comprising:
[0007] The evaporator assembly is connected to the gas collecting pipe assembly and the liquid inlet pipe assembly;
[0008] The gas collecting pipe assembly includes a first gas collecting pipe and a second gas collecting pipe, wherein the outlet directions of the first gas collecting pipe and the second gas collecting pipe are different.
[0009] The liquid inlet assembly includes a first liquid inlet pipe and a second liquid inlet pipe, with the first liquid inlet pipe and the second liquid inlet pipe having different outlet directions.
[0010] Preferably, the gas collecting pipe assembly further includes a first distributor, and both the first gas collecting pipe and the second gas collecting pipe are connected to the first distributor. The gas collecting pipe assembly is connected to the evaporator assembly through the first distributor.
[0011] Preferably, a first valve is provided at the end of the first gas collecting pipe and the second gas collecting pipe away from the evaporator assembly, for selectively sealing either the first gas collecting pipe or the second gas collecting pipe.
[0012] Preferably, the liquid inlet pipe assembly further includes a second distributor, wherein both the first liquid inlet pipe and the second liquid inlet pipe are connected to the second distributor, and the liquid inlet pipe assembly is connected to the evaporator assembly through the second distributor.
[0013] Preferably, a second valve is provided at the end of the first liquid inlet pipe and the second liquid inlet pipe away from the evaporator assembly, for selectively sealing either the first liquid inlet pipe or the second liquid inlet pipe.
[0014] Preferably, the first gas collecting pipe and the second gas collecting pipe exit towards both sides of the evaporator assembly.
[0015] Preferably, the first liquid inlet pipe and the second liquid inlet pipe exit towards both sides of the evaporator assembly.
[0016] Preferably, the duct machine further includes a duct machine housing, and the duct machine housing is provided with a passageway for placing the second air collection pipe and the second liquid inlet pipe.
[0017] Preferably, the longitudinal section of the tube is trapezoidal.
[0018] Preferably, a fixing hook is provided inside the pipe cavity, and the second gas collecting pipe and the second liquid inlet pipe are connected by a wire tie. The wire tie is connected to the fixing hook. The outdoor unit connecting pipe can also be fixed to the fixing hook in this way. The second gas collecting pipe and the second liquid inlet pipe can also be tied or fixed by using Teflon tape or insulation sleeve instead of wire tie. Other methods can also be used to fix the second gas collecting pipe and the second liquid inlet pipe.
[0019] A second aspect of the present invention provides an air conditioner, including the ducted air conditioner provided in the first aspect of the present invention.
[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0021] This invention provides a first and second gas collecting pipe with different outlet directions, as well as a first and second liquid inlet pipe with different outlet directions, allowing for the selection of the appropriate outlet direction gas collecting pipe and liquid inlet pipe during installation. Compared to existing technologies, this invention eliminates the need to lengthen connecting pipes and forcibly bend pipes when changing the outlet direction, effectively reducing the risk of pipeline leakage and pipe breakage.
[0022] In addition, by setting the first distributor, the refrigerant can be controlled to enter the selected gas collection pipe, and by setting the second distributor, the refrigerant can be controlled to enter the selected liquid inlet pipe, ensuring the normal operation of the air conditioner;
[0023] By closing the first valve of the unselected air collection pipe, the air collection pipe can be sealed to prevent external impurities from entering the air collection pipe. By closing the second valve of the unselected liquid inlet pipe, the liquid inlet pipe can be sealed to prevent external impurities from entering the liquid inlet pipe. This prevents impurities from affecting the operation of the duct air conditioner and ensures the normal operation of the air conditioner.
[0024] The first and second gas collecting pipes exit from both sides of the evaporator assembly, and the first and second liquid inlet pipes exit from both sides of the evaporator assembly. When the gas collecting pipe and liquid inlet pipe on one side cannot meet the installation requirements, the gas collecting pipe and liquid inlet pipe on the other side can be selected to continue the installation work without the need to lengthen the connecting pipe or forcibly bend the pipe, which effectively reduces the risk of pipe leakage and pipe breakage, improves work efficiency, and reduces costs.
[0025] Setting up a trapezoidal cross-section for the conduit cavity to house the second gas collection pipe and the second liquid inlet pipe ensures that the pipeline does not exceed the bottom surface of the duct unit housing, without increasing the size of the duct unit housing, thus maintaining overall aesthetics and improving overall strength.
[0026] The second gas collecting pipe and the second liquid inlet pipe are connected together by wire ties to prevent shaking and improve overall stability. The wire ties are then connected to the fixing hooks to fix the second gas collecting pipe, the second liquid inlet pipe and the air duct housing together, further preventing shaking and improving overall stability.

Detailed Implementation
[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this invention. The embodiments described in this application are merely some embodiments of this invention, and not all embodiments. Based on the spirit of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this invention.
[0034] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps described in these embodiments do not limit the scope of the invention.
[0035] At the same time, it should be understood that, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn according to actual scale.
[0036] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.
[0037] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.
[0038] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.
[0039] like Figure 1 , 2 As shown, Embodiment 1 of the present invention provides a ducted air conditioner. The piping layout provided by the present invention uses the first gas collecting pipe 2 and the first liquid inlet pipe 4 as outlet pipes on one side, the same as existing units. A second gas collecting pipe 3 and a second liquid inlet pipe 5 are added as outlet pipes on the other side, which can meet various indoor layout requirements after-sales service. It solves the problem that traditional units have unidirectional outlet pipes (left or right), making it difficult to meet the reverse outlet pipe requirement. After-sales service does not require lengthening the connecting pipe and forcibly bending it to meet the reverse outlet pipe requirement, effectively reducing the risk of pipe leakage and breakage. After-sales installation quality is more reliable, and the after-sales connection method is consistent with conventional after-sales piping connection methods, without adding other installation steps, thus avoiding cumbersome installation steps. It retains the convenience of traditional unit piping layout installation and does not increase after-sales installation costs. The ducted air conditioner includes an evaporator component and a ducted air conditioner housing. The evaporator component includes:
[0040] Evaporator assembly 1 is connected to the gas collecting pipe assembly and the liquid inlet pipe assembly;
[0041] The gas collecting pipe assembly includes a first gas collecting pipe 2 and a second gas collecting pipe 3, wherein the outlet directions of the first gas collecting pipe 2 and the second gas collecting pipe 3 are different.
[0042] The liquid inlet pipe assembly includes a first liquid inlet pipe 4 and a second liquid inlet pipe 5, with the first liquid inlet pipe 4 and the second liquid inlet pipe 5 having different outlet directions.
[0043] During installation, select the appropriate gas collection pipe and liquid inlet pipe with the appropriate outlet direction as needed. Compared with existing technologies, there is no need to lengthen the connecting pipe or forcibly bend the pipe when changing the outlet direction, which effectively reduces the risk of pipeline leakage and pipe breakage.

By running the pipes through the pipe passage cavity 10, the pipes can be kept below the bottom surface of the ducted air conditioner housing without increasing the size of the housing, ensuring overall aesthetics.

[0063] It can improve overall stability.
[0064] Preferably, but not limitingly, the duct housing includes a lower cover plate 13, a return air cover plate 14, and a sealing cover plate 15.

One end of the duct cavity 10 is closed, and the side of the sealing cover plate 15 is the side wall of the closed end of the duct cavity 10. The other end is open for pipe outlet. The fixing hook 11 is provided on the return air cover plate 14.
[0065] It facilitates the placement of the second gas collecting pipe 3 and the second liquid inlet pipe 5.
[0066] Preferably, but not limitingly, the ducted air conditioner further includes a fan component 16, the fan component 16 and the evaporator assembly 1 are both located inside the ducted air conditioner housing, the duct cavity 10 is located between the fan component 16 and the evaporator assembly 1, the duct cavity 10 is located at the bottom end of the ducted air conditioner housing, below the fan component 16 and the return air cover 14, and the ducting direction of the second air collection pipe 3 and the second liquid inlet pipe 5 is the length direction of the duct cavity 10, and the ducting direction is perpendicular to the direction of the line connecting the fan component 16 and the evaporator assembly 1.

[0069] Ensure overall sealing performance.
[0070] Embodiment 3 of the present invention provides an air conditioner, including the ducted air conditioner provided in Embodiment 1 or Embodiment 2 of the present invention.
[0071] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0072] This invention provides a first and second gas collecting pipe with different outlet directions, as well as a first and second liquid inlet pipe with different outlet directions, allowing for the selection of the appropriate outlet direction gas collecting pipe and liquid inlet pipe during installation. Compared to existing technologies, this invention eliminates the need to lengthen connecting pipes and forcibly bend pipes when changing the outlet direction, effectively reducing the risk of pipeline leakage and pipe breakage.
[0073] In addition, by setting the first distributor, the refrigerant can be controlled to enter the selected gas collection pipe, and by setting the second distributor, the refrigerant can be controlled to enter the selected liquid inlet pipe, ensuring the normal operation of the air conditioner;
[0074] By closing the first valve of the unselected air collection pipe, the air collection pipe can be sealed to prevent external impurities from entering the air collection pipe.

This prevents impurities from affecting the operation of the duct air conditioner and ensures the normal operation of the air conditioner.
[0075] The first and second gas collecting pipes exit from both sides of the evaporator assembly, and the first and second liquid inlet pipes exit from both sides of the evaporator assembly. When the gas collecting pipe and liquid inlet pipe on one side cannot meet the installation requirements, the gas collecting pipe and liquid inlet pipe on the other side can be selected to continue the installation work without the need to lengthen the connecting pipe or forcibly bend the pipe, which effectively reduces the risk of pipe leakage and pipe breakage, improves work efficiency, and reduces costs.
[0076] Setting up a trapezoidal cross-section for the conduit cavity to house the second gas collection pipe and the second liquid inlet pipe ensures that the pipeline does not exceed the bottom surface of the duct unit housing, without increasing the size of the duct unit housing, thus maintaining overall aesthetics and improving overall strength.
[0077] The second gas collecting pipe and the second liquid inlet pipe are connected together by wire ties to prevent shaking and improve overall stability.
