Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of air conditioners, and particularly relates to an indoor unit and an air conditioner. BACKGROUND

[0002] An air conditioner usually realizes refrigeration or heating functions through circulation of refrigerant. In the refrigeration process, the refrigerant can absorb indoor heat and release to the outdoor through a condenser; in the heating process, the refrigerant can absorb outdoor heat and release to the indoor, so as to adjust the indoor temperature.

[0003] During use, the refrigerant may have a risk of leakage. Once leakage occurs, not only the refrigeration or heating effect of the air conditioner is affected, but also the environment is polluted. Therefore, in the related art, a refrigerant sensor is usually installed in the air conditioner to monitor the state of the refrigerant in real time, so as to discover and handle the leakage in time.

[0004] However, the installation of the refrigerant sensor is relatively complex, and there is a problem of inconvenient maintenance. UTILITY MODEL CONTENT

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0046] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0047] Furthermore, the terms "set up," "connect," and "fix" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this disclosure according to the specific circumstances.

[0048] Unless otherwise stated, the term "multiple" means two or more.

[0049] As can be seen from the background technology, refrigerant plays a role in heat transfer during the cooling and heating process of air conditioning, and it can effectively absorb and release heat at different temperatures.

[0050] During the installation and use of air conditioners, refrigerant leaks may occur due to aging or loosening of pipes. Refrigerant leaks reduce the amount of refrigerant in the air conditioning system, thus affecting its cooling or heating performance. Refrigerant leaks can also pollute the environment, especially since certain types of refrigerants (such as Freon) are ozone layer depletion-causing agents.

[0051] Therefore, in order to detect and address refrigerant leaks promptly, air conditioners typically have refrigerant sensors installed inside. Different refrigerant sensors use different technical principles to detect refrigerant leaks.

[0052] Taking a thermal conductivity sensor as an example, it accurately detects the concentration of refrigerant in the air by measuring changes in the thermal conductivity of a gas mixture. When refrigerant leaks and mixes with the air, it changes the air's thermal conductivity. The thermal conductivity sensor can quickly capture this change and convert it into an electrical signal for output, thereby enabling real-time monitoring of refrigerant leaks.

[0053] Refrigerant sensors are typically installed in critical parts of air conditioning systems and require regular inspection and calibration to ensure their accuracy and reliability.

[0054] However, the installation of refrigerant sensors in the prior art usually involves fixing them in multiple locations with multiple screws. When fixing them in each location, the screw holes also need to be aligned, which makes the installation relatively complicated and affects the maintenance efficiency of the refrigerant sensor.

[0055] To address the aforementioned problems, this application provides an indoor unit and an air conditioner. The indoor unit includes an air-exhausting component, a mounting structure, and a refrigerant sensor. The mounting structure is disposed on the air-exhausting component and includes a first mounting member and a second mounting member spaced apart. The refrigerant sensor includes a housing with a plug-in portion and a connecting portion located at opposite corners of the housing. The plug-in portion plugs into the first mounting member, and the connecting portion connects to the second mounting member. The spaced-apart first and second mounting members, combined with the plug-in and connecting portions on the housing, form a stable and easy-to-operate connection structure, ensuring the stability and reliability of the sensor during use. Furthermore, the plug-in connection between the plug-in portion and the first mounting member simplifies installation, reduces the complexity of traditional multi-screw fixing, and helps provide positioning for the connection between the connecting portion and the second mounting member, reducing installation complexity and errors, and improving the installation and maintenance efficiency of the refrigerant sensor.

[0056] The technical solutions of this application and how they solve the aforementioned technical problems are described in detail below with specific embodiments. These specific embodiments may exist independently or in combination with each other. Identical or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0057] Combination Figure 1 and Figure 2 As shown, one embodiment of this application provides an indoor unit, including an air duct 100, a mounting structure 200, and a refrigerant sensor 300; the mounting structure 200 is disposed on the air duct 100, and the mounting structure 200 includes a first mounting member 210 and a second mounting member 220 disposed at intervals; the refrigerant sensor 300 includes a housing 310, the housing 310 is provided with a plug-in portion 311 and a connecting portion 312, the plug-in portion 311 and the connecting portion 312 are located at a pair of corners of the housing 310, the plug-in portion 311 is plugged into the first mounting member 210, and the connecting portion 312 is connected to the second mounting member 220.

[0058] Among them, the air-inducing component 100 is the air-inducing ring.

[0059] Taking a ceiling-mounted air conditioner as an example, a ceiling-mounted air conditioner typically includes a fan (not shown in the figure) and an air guide ring. The air guide ring can be set on the air inlet side of the fan, and an air inlet 101 is provided on the air guide ring. An arc-shaped air guide ring 102 is provided on the edge of the air inlet 101. The main function of the air guide ring 102 is to guide the airflow to optimize the airflow path.

[0060] The air intake ring can diffuse the airflow and slow down the airflow velocity. Slowing down the velocity helps to increase the uniformity of the airflow, reduce noise and vibration caused by excessive airflow velocity, and also allows more air to enter the fan more smoothly, improving overall efficiency.

[0061] By placing the refrigerant sensor 300 on the air intake ring, detection can be performed on the air intake side of the fan to quickly detect changes in the refrigerant concentration in the air.

[0062] The mounting structure 200 is a structure for fixing the refrigerant sensor 300, including a first mounting member 210 and a second mounting member 220, which are arranged at a certain interval on the air duct 100.

[0063] Mounting structure 200 provides a solid foundation, ensuring that refrigerant sensor 300 can remain stable during air conditioner operation.

[0064] The first mounting member 210 and the second mounting member 220 are spaced apart, so that the refrigerant sensor 300 can be fixed at two different points. This multi-point fixing method improves the stability of the refrigerant sensor 300.

[0065] The plug-in portion 311 and the connecting portion 312 provided on the housing 310 of the refrigerant sensor 300 allow the refrigerant sensor 300 to be fixed to the mounting structure 200 by a simple mechanical connection, reducing the complexity of traditional multi-screw fixing.

[0066] The plug-in connection between the plug-in part 311 and the first mounting part 210 provides a quick and simple installation method, reduces installation time and the need for aligning the nail holes, reduces human error during the installation process, and improves installation efficiency.

[0067] The plug-in connection between the plug-in part 311 and the first mounting member 210 also helps to provide positioning for the connection between the connecting part 312 and the second mounting member 220, reducing the complexity and errors during installation and improving the installation and maintenance efficiency of the refrigerant sensor 300.

[0068] The connection between the connecting part 312 and the second mounting part 220 provides additional support and fixation, ensuring that the refrigerant sensor 300 will not shift due to vibration or other external forces during use.

[0069] For example, the connecting part 312 and the second mounting part 220 can be connected by screws, or by snap-fit, clamp or other quick connection methods.

[0070] Specifically, by placing the plug-in portion 311 and the connecting portion 312 at a pair of corners of the housing 310, a fixed geometric relationship can be naturally formed during installation, which helps to automatically correct the position during installation, reduce human error, and improve installation accuracy.

[0071] During installation, you only need to focus on the alignment of two key points, instead of aligning and fixing in multiple locations. This simplifies the installation process and reduces installation time and complexity.

[0072] By setting fixed points at both ends of a pair of corners of the shell, the force is distributed more evenly in the diagonal direction, which can improve the deformation resistance of the shell 310.

[0073] Furthermore, the diagonal arrangement of the plug-in portion 311 and the connecting portion 312 can make better use of the space in the housing 310, enabling the refrigerant sensor 300 to achieve a better installation effect in a limited space without affecting the layout and function of other components.

[0074] Specifically, the indoor unit provided in this application embodiment features a refrigerant sensor 300 securely mounted on the air intake component 100, which improves the accuracy and reliability of its detection, ensuring that the indoor unit can detect and respond promptly when refrigerant leakage occurs. Furthermore, by simplifying the mounting structure 200 of the refrigerant sensor 300, the use of screws is reduced, thereby reducing installation complexity and time, and improving the installation and maintenance efficiency of the refrigerant sensor 300.

[0075] Combination Figures 2 to 4 As shown, in some embodiments, when the plug-in portion 311 is plugged into the first mounting member 210, the connecting portion 312 can be opposite to the second mounting member 220.

[0076] The plug-in part 311 engages with the first mounting part 210, providing a quick and simple installation method.

[0077] By using a plug-in connection, installers can quickly fix the refrigerant sensor 300 onto the first mounting component 210 without the need for tools or complex alignment operations, reducing installation time, improving installation efficiency, and minimizing human error during the installation process.

[0078] After the insertion part 311 is inserted and engaged with the first mounting member 210, the connecting part 312 can naturally be aligned with the second mounting member 220. That is, after the insertion is completed, the position of the connecting part 312 is already aligned with the position of the second mounting member 220.

[0079] This design ensures that after the insertion part 311 is fixed, the connecting part 312 automatically aligns with the position of the second mounting member 220, simplifying subsequent connection operations. Installers do not need to perform additional adjustments or alignment operations; they can simply connect the connecting part 312 to the second mounting member 220. This automatic alignment method reduces installation steps and further improves installation efficiency.

[0080] During installation, the plug-in part 311 is plugged into the first mounting member 210, at which point the connecting part 312 naturally aligns with the second mounting member 220. After connecting the connecting part 312 to the second mounting member 220, the refrigerant sensor 300 is installed.

[0081] Specifically, the refrigerant sensor 300 is quickly and easily installed through the insertion and engagement of the plug-in part 311 with the first mounting part 210, and the automatic alignment of the connecting part 312 with the second mounting part 220, reducing the technical skill requirements for installers. This design not only improves installation efficiency and accuracy but also enhances the stability and reliability of the refrigerant sensor 300, ensuring its normal operation in the air conditioning system.

[0082] In some embodiments, the first mounting member 210 is provided with a slot 211, which extends along a first direction. In the first direction, the end of the slot 211 facing the second mounting member 220 has an opening. The insertion part 311 is inserted into the slot 211 through the opening, and at least a portion of the insertion part 311 abuts against the first mounting member 210.

[0083] Understandable, the first direction and Figure 3 The X-axis is parallel to the first direction. The insertion part 311 can be inserted into the slot 211 along the first direction.

[0084] The orientation of slot 211 defines the insertion direction of connector 311, which can ensure that refrigerant sensor 300 is in the correct working position and orientation after installation, reducing orientation errors during installation.

[0085] The slot 211 has an opening in the first direction, which faces the second mounting member 220. The opening is designed so that the plug part 311 can be inserted from one end of the slot 211, which not only simplifies the installation process, but also ensures that the connector 312 can automatically align with the position of the second mounting member 220 after the plug part 311 is inserted, reducing the complexity of subsequent connections.

[0086] The plug portion 311 is inserted into the slot 211 and abuts against the first mounting member 210, so that the connecting portion 312 is opposite to the second mounting member 220. This abutment provides additional stability and support, preventing the plug portion 311 from shaking or shifting within the slot 211, thus ensuring that the connecting portion 312 and the second mounting member 220 are stably opposite each other, facilitating a fixed connection between the connecting portion 312 and the second mounting member 220.

[0087] In some embodiments, the connecting part 312 is provided with a connecting hole 3121, and the second mounting member 220 is provided with a threaded hole 221; when the plug-in part 311 is plugged into the first mounting member 210, the connecting hole 3121 and the threaded hole 221 are opposite to and communicate with each other; the indoor unit also includes a locking member 400, which passes through the connecting hole 3121 and is connected to the second mounting member 220 through the threaded hole 221.

[0088] Understandably, the threaded hole 221 allows the connecting part 312 to be securely fixed to the second mounting part 220 by the locking member 400.

[0089] After the insertion part 311 is engaged with the first mounting member 210, the connecting hole 3121 and the threaded hole 221 naturally align and connect. This design ensures that the connecting hole 3121 and the threaded hole 221 automatically align after insertion, simplifying the subsequent locking operation. Installers do not need to perform any additional alignment operations; they only need to insert the locking member 400. This automatic alignment reduces installation steps and further improves installation efficiency.

[0090] For example, the locking element 400 can be a screw. The locking element 400 provides a simple and effective way to secure the connecting part 312 to the second mounting part 220, enabling a quick and secure connection and ensuring the stability of the refrigerant sensor 300 during use.

[0091] Combination Figure 2 and Figure 3 As shown, in some embodiments, the mounting structure 200 further includes a guide extending in a first direction; when the insertion portion 311 is inserted into the first mounting member 210, the guide slides into contact with the housing 310 to guide the housing 310.

[0092] The guide can provide a guiding path for the installation process of the refrigerant sensor 300, ensuring that the refrigerant sensor 300 moves in a predetermined direction during installation.

[0093] The guide extends along the first direction and is aligned with the direction of the slot 211, ensuring that the refrigerant sensor 300 can slide in the correct direction during installation. By defining the sliding direction, it is ensured that the refrigerant sensor 300 is in the correct operating position and orientation after installation.

[0094] During the insertion and engagement of the connector 311 and the first mounting member 210, the guide member maintains sliding contact with the housing 310 of the refrigerant sensor 300, thereby guiding the housing 310 and allowing the refrigerant sensor 300 to slide smoothly into place.

[0095] Specifically, by guiding the housing 310, installers can more easily install the refrigerant sensor 300, reducing alignment and adjustment time, improving the convenience and accuracy of installation, and reducing human error during the installation process.

[0096] In some embodiments, the guide includes a first guide 230 and a second guide 240, which are distributed on both sides of the housing 310 along a first direction.

[0097] Understandably, the first guide member 230 and the second guide member 240 are along... Figure 3 The Y-axis arrangement is distributed on both sides of the outer shell 310 along the first direction.

[0098] This symmetrical arrangement provides dual-sided support for the housing 310, ensuring the refrigerant sensor 300 remains balanced during installation. The dual-sided guides also effectively prevent lateral movement or rotation of the housing 310, improving installation accuracy and stability.

[0099] Specifically, by providing guides on both sides of the housing 310, the refrigerant sensor 300 receives better support and guidance during installation. The dual-sided guides allow the refrigerant sensor 300 to automatically align and maintain the correct orientation during installation, reducing tilting or misalignment issues that might occur with single-sided guidance. Furthermore, the first guide 230 and the second guide 240 provide additional support after the refrigerant sensor 300 is fixed in place, enhancing its vibration resistance and ensuring stability during operation.

[0100] Combination Figure 2 and Figure 3 As shown, in some embodiments, the mounting structure 200 further includes at least one support member 250, the extension direction of the support member 250 is parallel to the first direction, the support member 250 is disposed between the first guide member 230 and the second guide member 240, and the support member 250 abuts against the side of the housing 310 facing the air duct member 100.

[0101] Understandably, by adding a support member 250 that abuts against the side of the housing 310 facing the air intake member 100, the refrigerant sensor 300 can obtain an additional support point in the mounting structure 200, reducing the displacement of the refrigerant sensor 300 when subjected to external forces or vibrations, and improving the overall stability.

[0102] The extension direction of the support member 250 is parallel to the first direction, maintaining the same orientation as the guide member. This can provide consistent support force during the installation of the refrigerant sensor 300, preventing the refrigerant sensor 300 from shifting or tilting when moving along the first direction.

[0103] Furthermore, since the extension direction of the support member 250 is parallel to the first direction, the contact area between the housing 310 and the support member 250 is always small when the housing 310 slides along the first direction. This also helps to keep the frictional resistance between the support member 250 and the housing 310 always small, which facilitates the smooth sliding of the refrigerant sensor 300 and improves the ease of assembly.

[0104] In some embodiments, the first mounting member 210, the second mounting member 220, the guide member, and the support member 250 can all be directly and integrally disposed on the surface of the air duct 100 facing the refrigerant sensor 300, so as to improve the connection effect between the mounting structure 200 and the air duct 100 and facilitate the stable connection of the refrigerant sensor 300.

[0105] Combination Figure 1 and 5 As shown, in some embodiments, the mounting structure 200 further includes a connecting plate 260, and the first mounting member 210 and the second mounting member 220 are both disposed on the connecting plate 260; the air duct 100 has a first surface and a second surface disposed opposite to each other, the side of the connecting plate 260 near the first mounting member 210 abuts against the first surface, and the refrigerant sensor 300 is located on the second surface.

[0106] By integrating the first mounting component 210 and the second mounting component 220 onto the same connecting plate 260 to form an integral mounting structure 200, the manufacturing of the mounting structure 200 can be facilitated, thereby reducing the processing difficulty of the air duct component 100.

[0107] The second surface typically faces the area of ​​airflow. The refrigerant sensor 300 is mounted on the second surface of the air intake 100, ensuring that the refrigerant sensor 300 can effectively detect refrigerant leaks in the air, thus improving the detection efficiency and sensitivity of the refrigerant sensor 300.

[0108] In some embodiments, the threaded hole 221 can be directly formed on the connecting plate 260 to reduce the number of parts in the mounting structure 200 and reduce the difficulty of processing and assembly.

[0109] In other embodiments, the second mounting member 220 may be a protrusion provided on the surface of the connecting plate 260, and a threaded hole 221 is formed on the protrusion.

[0110] Combination Figure 3 and Figure 5 As shown, in some embodiments, the air duct 100 is provided with a receiving groove 110, the first mounting member 210 is disposed in the receiving groove 110, and at least a portion of the slot 211 is located on the second surface.

[0111] By providing a receiving groove 110 on the air intake 100, an installation position can be provided for the first mounting member 210 so that the first mounting member 210 can pass through the receiving groove 110 and extend to the second surface.

[0112] At least part of the slot 211 is located on the second surface, which facilitates the connection of the refrigerant sensor 300 located on the second surface.

[0113] The number of receiving slots 110 is at least two, and the positions of the two receiving slots 110 correspond one-to-one with the first mounting member 210 and the second mounting member 220.

[0114] When the second mounting member 220 is a threaded hole 221 opened on the connecting plate 260, the threaded hole 221 communicates with the connecting hole 3121 on the connecting part 312 via the receiving groove 110. The locking member 400 passes through the connecting hole 3121 and the receiving groove 110 in sequence, and is threadedly connected to the connecting plate 260 through the threaded hole 221.

[0115] When the second mounting part 220 is a protrusion provided on the surface of the connecting plate 260, the protrusion can pass through the receiving groove 110 so that the threaded hole 221 is located on the second surface to enable connection with the refrigerant sensor 300.

[0116] During installation, the connecting plate 260 of the mounting structure 200 is attached to the first surface of the air duct 100 so that the first mounting member 210 extends to the second surface through the receiving groove 110, and the second mounting member 220 also extends to the second surface through another receiving groove 110. Finally, the refrigerant sensor 300 is installed from the second surface onto the mounting structure 200.

[0117] The connecting plate 260 of the mounting structure 200 is attached to the first surface of the air duct 100. The first mounting member 210 and the second mounting member 220 extend to the second surface of the air duct 100 through the receiving groove 110 and are fixed to the refrigerant sensor 300. In this way, the mounting structure 200, the refrigerant sensor 300 and the air duct 100 are fixed together, ensuring the stability of the entire structure.

[0118] Another aspect of this application provides an air conditioner, including the indoor unit provided in any of the above embodiments.

[0119] The indoor unit has been described in detail in the above embodiments and will not be repeated here.

[0120] The technical solutions of this application have been described above with reference to the preferred embodiments shown in the accompanying drawings.
