Description

Technical Field

[0001] This utility model relates to the field of duct indoor unit technology, and more specifically, to a duct indoor unit. Background Technology

[0002] Currently, ducted indoor units are generally installed in the ceiling or partition walls of a room. A ducted indoor unit typically includes a fan component and an indoor unit casing. The airflow generated by the fan component is delivered into the room through the air outlet of the indoor unit casing, thereby achieving the purpose of regulating the indoor air.

[0003] However, most ducted indoor units on the market have fixed airflow and duct outlet directions. During installation, if the airflow direction is determined but the actual duct outlet direction of the indoor unit differs from the planned direction, or if the actual duct outlet direction is unfavorable for installation (e.g., limited space for connecting pipes), changing the duct outlet direction by rotating the entire unit left or right will cause problems with the drip tray and water pump, and may also cause the electronic expansion valve to become inverted, resulting in the indoor unit malfunctioning. Therefore, existing ducted indoor units can only be installed on the left or right, and cannot be switched between left and right installations, thus lacking flexibility in adjusting the installation method.

[0050] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0051] like Figures 1 to 4As shown, Embodiment 1 of this utility model provides a ducted indoor unit. The ducted indoor unit includes an indoor unit housing 10, a fan component 20, and a connecting component 30. The indoor unit housing 10 has a first connecting port 11 and a second connecting port 12 disposed opposite to each other, and a mounting cavity 13 communicating with both the first connecting port 11 and the second connecting port 12. The fan component 20 is disposed within the mounting cavity 13. The connecting component 30 is disposed on the side of the indoor unit housing 10 and is used to connect with an external structure. The ducted indoor unit has a first installation state and a second installation state. When the ducted indoor unit is in the first installation state, the fan component 20 discharges air towards the first connecting port 11, which is located at the air outlet of the mounting base, so that the connecting component 30 is located on one side of the mounting base. When the ducted indoor unit is in the second installation state, the fan component 20 discharges air towards the second connecting port 12, which is located at the air outlet of the mounting base, so that the connecting component 30 is located on the other side of the mounting base.

[0052] The ducted indoor unit provided in this embodiment features a design that allows for adjustment of the installation state according to actual space requirements, greatly improving installation flexibility. Furthermore, when adjusting the ducted indoor unit to either the first or second installation state, the connecting component 30 is positioned on one or the other side of the mounting base, facilitating adaptive adjustment of the connecting component 30 based on the location of the external structure and thus simplifying its connection to the external structure. In addition, the ducted indoor unit in this embodiment ensures normal operation in both the first and second installation states, enabling smooth air intake and exhaust. Therefore, the technical solution provided by this invention solves the technical problem of the inability to adjust the installation method of ducted indoor units in existing technologies.

[0053] Specifically, one of the first and second installation states corresponds to left-hand installation, and the other corresponds to right-hand installation. The installation base can be a wall.

[0054] Specifically, the indoor unit housing 10 is a square housing.

[0055] The duct indoor unit provided in this embodiment is suitable for various installation environments, such as homes, offices, shopping malls, etc. It is especially suitable for places with complex spatial layouts or special needs, such as multi-story commercial spaces or residential areas where the impact of wind direction on interior decoration needs to be considered. It can better meet user needs and improve the comfort and efficiency of air conditioning.

[0056] In this embodiment, the fan component 20 has an air outlet 21, and the fan component 20 is adjustablely positioned within the mounting cavity 13 to be in a first mounting position or a second mounting position. When the fan component 20 is in the first mounting position, the air outlet 21 faces the first connecting port 11; when the fan component 20 is in the second mounting position, the air outlet 21 faces the second connecting port 12. By changing the position of the fan component 20, the airflow direction can be easily adjusted, ensuring that the indoor unit of the duct can smoothly outlet air towards the air outlet of the mounting base in both the first and second mounting states. Furthermore, the above setup eliminates the need for additional duct adjustments or repositioning of the indoor unit, reducing installation costs and complexity. It is particularly suitable for scenarios where the air conditioning outlet direction needs adjustment after renovation, such as adjusting the air conditioning outlet direction after home renovation based on changes in furniture layout to achieve optimal indoor comfort, or adjusting the air conditioning outlet to adapt to the new work area requirements after office space redesign. This flexibility significantly improves user experience and space utilization efficiency.

[0057] In one embodiment, the duct indoor unit further includes a drive component installed within the mounting cavity 13. The drive end of the drive component is driven to the housing of the fan component 20 to move the fan component 20 to a first mounting position or a second mounting position. With this configuration, the addition of the drive component automates the adjustment process of the fan component 20. Users or installers only need to control the operation of the drive component to change the airflow direction, improving the user experience.

[0058] In another embodiment, the indoor unit housing 10 includes a main body 14 and a disassembly / removal part 15 connected to each other. The main body 14 has an installation notch adapted to the fan component 20, and the disassembly / removal part 15 is detachably installed at the installation notch. The fan component 20 is removed or installed through the installation notch to adjust the fan component 20 to a first installation position or a second installation position. This modular design not only simplifies the adjustment process of the fan component 20, but also facilitates installation, maintenance, and replacement, making it particularly suitable for large-scale installation and maintenance in commercial buildings.

[0059] Specifically, the disassembly section 15 is located at the bottom of the main body 14. The bottom disassembly design makes it easier to adjust the fan component 20 without moving the entire indoor unit, reducing physical labor during installation and adjustment. It is suitable for environments such as homes and small offices where the airflow direction needs to be adjusted frequently. Especially for those scenarios where space is limited and moving the indoor unit may cause inconvenience to furniture and layout, the bottom disassembly design not only saves space but also simplifies the adjustment process and improves the user's ease of operation.

[0060] Specifically, the disassembly / assembly section 15 is a disassembly / assembly cover plate.

[0061] In this embodiment, the main body 14 is provided with a first connecting portion, and the detachable part 15 is provided with a second connecting portion adapted to the first connecting portion. The first connecting portion is used to connect with the second connecting portion. This arrangement facilitates the connection stability between the main body 14 and the detachable part 15. Specifically, the first connecting portion and the second connecting portion can be connected by snap-fit; or, both the first connecting portion and the second connecting portion are connecting holes, and a locking member passes through the first connecting hole and the second connecting hole and locks into the main body 14.

[0062] In this embodiment, at least a portion of the fan component 20 is detachably mounted on the indoor unit housing 10. This detachable design not only facilitates the adjustment, replacement, and maintenance of the fan component 20, but also allows users to select different types of fan components 20 as needed to adapt to different airflow requirements and noise control requirements.

[0063] Specifically, the fan component 20 includes a mounting part 22 and a fan 23, with a clearance opening provided on the mounting part 22. The fan 23 is mounted on the mounting part 22 and located on one side of the mounting part 22, with its air outlet 21 facing the clearance opening. Specifically, when the fan component 20 is in the first mounting position, the fan 23 is located on the side of the mounting part 22 closer to the second connecting port 12; when the fan component 20 is in the second mounting position, the fan 23 is located on the side of the mounting part 22 closer to the first connecting port 11. The clearance opening design ensures that the fan component 20 can normally discharge air towards the air outlet of the mounting base when adjusted to both the first and second mounting positions, meaning that the indoor unit of the duct can normally discharge air in both the first and second mounting states.

[0064] Specifically, the mounting section 22 is a mounting plate.

[0065] Specifically, the fan component 20 also includes a motor 26 and fan blades, with the motor 26 driving the fan blades to rotate.

[0066] In this embodiment, a first guide portion is provided on the indoor unit housing 10, and a second guide portion adapted to the first guide portion is provided on the mounting portion 22. At least one of the first and second guide portions extends along the disassembly / removal direction of the mounting portion 22. The first and second guide portions guide and cooperate to allow the mounting portion 22 to be installed into or removed from the indoor unit housing 10. The guide portion simplifies the installation and disassembly process of the fan component 20, ensures the accuracy and stability of the installation, is suitable for temporary locations requiring rapid installation and disassembly, improves installation and switching efficiency, and also ensures stable operation of the system under different conditions, enhancing the comfort and work efficiency of temporary spaces.

[0067] During installation, the direction of the fan component 20 can be adjusted to switch between left-side and right-side installation, meeting the different ductwork direction requirements of various projects. Facing the air outlet direction of the unit, indoor units with the gas duct, liquid duct, drain pipe, and electrical control on the left are left-side installed, while those on the right are right-side installed. Figure 1 and Figure 2 The image shows a left-side duct-mounted indoor unit. Figure 2 The arrows in the diagram indicate the direction of airflow. For example... Figure 3 and Figure 4 The image shows a right-side duct-mounted indoor unit. Figure 4 The arrows in the diagram represent the direction of airflow.

[0068] The indoor unit of this patent includes a main body 14, a fan component 20, and a lower cover plate (corresponding to the disassembly part 15). The main body 14 (connecting component 30) includes the necessary indoor unit housing 10, evaporator, water tray, water pump, and electrical control. The structure of the fan component 20 installed on the main body is consistent with the structure of the original left-side air inlet 25 to ensure that the fan component 20 can be switched smoothly. The installation structure here can be screwed, clipped, or slid in by a track. When a right-side installation is required due to limited space for the exhaust duct or pre-planned routes for exhaust ducts and gas / liquid pipes, simply remove the bottom cover of the duct unit and remove the entire fan assembly 20 from below (the advantage of removing it from below is that if the unit is already installed, changing the airflow direction can be achieved without disassembling the entire unit using this patented method). Rotate the fan assembly 20 horizontally 180 degrees to change its installation direction, then reinstall the bottom cover to complete the switch from left-side to right-side installation. If the duct unit is initially installed on the right, the same method can be used to switch to left-side installation. During installation, engineers can freely switch the installation method according to the actual installation conditions, without being limited by the original factory default exhaust duct position. The installation method is very flexible, providing more options for project installation and improving the convenience of project installation.

[0069] When switching from left-side to right-side installation, the indoor unit of the duct changes from the original blowing type to the suction type. A sensor for detecting air volume is installed on the evaporator, which can select the corresponding control mode according to different air outlet methods. At the same time, it can provide real-time monitoring of air volume to the control circuit to adjust the fan speed to ensure the unit's air volume and static pressure requirements.

[0070] In another embodiment, a ducted indoor unit is provided. The main difference between the ducted indoor unit in this embodiment and the one in the other embodiment lies in the structure of the fan component 20. The fan component 20 includes a volute 24, which has an air inlet 25, a first air outlet, and a second air outlet. The air inlet 25 can be selectively connected to either the first or the second air outlet. The first air outlet faces the first connecting port 11, and the second air outlet faces the second connecting port 12. This configuration allows the air outlet direction of the fan component 20 to be changed without adjusting its position, so that the ducted indoor unit can smoothly outlet air towards the air outlet of the mounting base in both the first and second installation states.

[0071] Specifically, the fan component 20 also includes a first baffle, which is movably disposed at the first air outlet to block or avoid the first air outlet. This allows air to be discharged through the first air outlet or to be closed off.

[0072] The fan component 20 also includes a second baffle, which is movably disposed at the second air outlet to block or avoid the second air outlet. This allows air to be discharged through the second air outlet or to be closed off.

[0073] In all the above embodiments, the connecting component 30 includes at least one of an air pipe, a liquid pipe, a drain pipe, and an electrical control, so as to facilitate the connection of the connecting component 30 with external components.

[0074] In all the above embodiments, at least a portion of the connecting member 30 protrudes from the side of the indoor unit housing 10. This positioning facilitates the connection of the connecting member 30 to external components.

[0075] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects: no additional materials are required, it is not limited by the existing outlet pipe direction, it provides more options for engineering installation, and the installation method is flexible. When the outlet pipe direction of the indoor unit is not conducive to engineering installation, such as when the pipe connection position is limited, left-side and right-side installation can be flexibly switched.
