Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. The description of at least one exemplary embodiment below is actually only illustrative and in no way limits the present utility model and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0026] In the description of the present utility model, it should be understood that orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. usually indicate the orientation or position relationship based on the orientation or position relationship shown in the attached drawings. They are only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, so they cannot be understood as limiting the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0027] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figure is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "under" the other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations will be made for the spatial relative descriptions used herein.

[0028] In addition, it should be noted that the use of terms such as "first" and "second" to define components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present utility model.

[0029] Referring to Figures 1 to 4 As shown, according to an embodiment of the present utility model, a heat exchanger assembly is provided, which includes a housing 1, a heat exchanger body 2, and a refrigerant detection member 3; the housing 1 has a first chamber 101 and a second chamber 102, and the heat exchanger body 2 is disposed in the first chamber 101 or the second chamber 102; the heat exchanger body 2 is provided with a mounting plate 201, the refrigerant detection member 3 includes a mounting end 31 and a detection end 32, the side of the mounting plate 201 facing the heat exchanger body 2 is a first wall surface 211, and the mounting end 31 is rotatably connected to the first wall surface 211, and the detection end 32 is close to the bottom of the heat exchanger body 2.

[0030] It is worth noting that according to different air outlet modes of the indoor unit, there are four installation modes for the heat exchanger assembly. When the indoor unit needs to have an upward air outlet, the heat exchanger body 2 is disposed in the second chamber 102; when the indoor unit needs to have a leftward air outlet, the housing 1 rotates counterclockwise 90° from the vertical state; when the indoor unit needs to have a rightward air outlet, the housing 1 rotates clockwise 90° from the vertical state. For the above three air outlet modes, the heat exchanger body 2 is disposed in the second chamber 102, and only the overall placement direction of the housing 1 is adjusted. When the indoor unit needs to have a downward air outlet, the housing 1 rotates counterclockwise 180° or clockwise 180° from the vertical state, or the heat exchanger body 2 is disposed in the first chamber 101.

[0031] Specifically, since one end of the refrigerant detection member 3 is rotatably connected to the first wall surface 211, when the housing 1 changes direction, one end of the refrigerant detection member 3 rotates, and the other end of the refrigerant detection member 3 is affected by gravity and always faces downward. In this way, the detection end 32 of the refrigerant detection member 3 is always in a lower position relative to the heat exchanger body 2, ensuring that the detection end 32 can detect refrigerant leakage in a timely manner.

[0032] In this embodiment, the refrigerant detection member 3 includes a mounting end 31 and a detection end 32. The mounting end 31 is rotatably connected to the mounting plate 201 of the heat exchanger body 2 to ensure that the detection end 32 is always close to the bottom of the heat exchanger body 2, and the detection end 32 is close to the bottom of the heat exchanger body 2. This setting allows the refrigerant detection member 3 to flexibly adjust its position in units with different installation directions to meet different installation requirements. Whether the housing 1 is installed vertically or horizontally, the usage requirements can be met. During the operation of the heat exchanger body 2, if refrigerant leakage occurs, the refrigerant gas will gradually accumulate at the bottom of the heat exchanger assembly. Since the detection end 32 is located near the bottom of the heat exchanger body 2, the refrigerant detection member 3 can detect the leaked refrigerant in a timely manner. The refrigerant detection member 3 ensures that the heat exchanger body 2 can effectively detect refrigerant leakage in various installation directions, thereby improving the safety and reliability of the heat exchanger.

[0033] Refer to the combination of Figures 1 to 5 As shown, a mounting hole is provided on the mounting plate 201, and a connecting column 4 is arranged in the mounting hole. The mounting end 31 is hinged to the connecting column 4 so that the mounting end 31 is rotatably connected to the first wall surface 211.

[0034] Specifically, according to the refrigerant detection requirements, a mounting hole is provided on the mounting plate 201. In the mounting hole, a connecting column 4 is arranged. The connecting column 4 is a mechanical component used to connect to the mounting end 31 of the refrigerant detection member 3, and the connecting column 4 is fixed or partially movable in the mounting hole. When the installation direction of the housing 1 changes, the mounting end 31 rotates relative to the connecting column 4, and under the action of gravity, the detection end 32 automatically adjusts its direction.

[0035] In this embodiment, for the installation of the refrigerant detection member 3, the installation end 31 is connected to the connecting column 4 in a hinged manner, allowing a degree of freedom of rotation between the two components and restricting movement in other directions. Through the hinged mechanism, the installation end 31 is rotatably connected to the first wall surface 211 (i.e., the side of the mounting plate 201 facing the heat exchanger body 2). The refrigerant detection member 3 can flexibly adjust its position to adapt to different installation directions and usage scenarios, whether it is upward air outlet, downward air outlet, leftward air outlet or rightward air outlet. Moreover, without changing the structure of the refrigerant detection member 3 itself, the heat exchanger assembly can adapt to different installation directions, which means that heat exchangers of the same model can be used in a variety of different application scenarios, avoiding complex fixing structures and eliminating the need to repeatedly adjust the installation position of the refrigerant detection member 3.

[0036] Referring to Figures 1 to 4 As shown, a motor is provided on the first wall surface 211, and the output end of the motor is connected to the installation end 31 to enable the installation end 31 to be rotatably connected to the first wall surface 211.

[0037] Specifically, when the installation direction of the housing 1 changes, the motor operates to drive the installation end 31 to rotate, thereby adjusting the position of the detection end 32 relative to the bottom of the heat exchanger body 2.

[0038] In this embodiment, by adopting the motor-driven method, the position of the detection end 32 can be optimized according to the installation direction (upward, downward, leftward, or rightward air outlet) of the heat exchanger, ensuring that it is always in the best detection position all the time. Through the automatic adjustment driven by the motor, the refrigerant detection member 3 can automatically adapt to the installation direction of the heat exchanger without manual intervention, and the automatic position adjustment mechanism of the refrigerant detection member 3 helps to promptly detect potential refrigerant leakage problems, so as to quickly take measures, reduce the accident risk, and improve the safety of the entire system.

[0039] Referring to Figures 1 to 4 As shown, a gear is sleeved on the output shaft of the motor, a connection hole is provided on the installation end 31, and internal teeth are provided on the inner wall of the connection hole, and the gear meshes with the internal teeth.

[0040] Specifically, when it is necessary to adjust the position of the refrigerant detection member 3, the motor is started, and the output shaft of the motor causes the gear sleeved on it to start rotating through power transmission. As the gear rotates, the gear meshes with the internal teeth on the inner wall of the connection hole on the installation end 31. This meshing mechanism allows the rotational movement of the gear to be transmitted to the installation end 31. Due to the meshing of the gear and the internal teeth, the installation end 31 will rotate as the gear rotates, realizing position adjustment; the rotation of the installation end 31 causes the position of the detection end 32 of the refrigerant detection member 3 to change, so that it can be adjusted to the required direction or position to adapt to different installation directions (upward, downward, leftward, or rightward air outlet) of the heat exchanger body 2.

[0041] In this embodiment, the meshing setting of the gear and the internal teeth makes the whole structure more compact, which helps to reduce the volume and weight of the heat exchanger assembly. Moreover, the combination of the motor and the gear provides a reliable driving method, which helps to improve the reliability and durability of the whole heat exchanger system. By driving the meshing of the gear and the internal teeth through the motor, the precise and automatic adjustment of the position of the refrigerant detection member 3 is realized, which improves the efficiency, safety and reliability of the system, reduces the maintenance cost at the same time, and enhances the adaptability of the heat exchanger assembly.

[0042] It should be noted that this embodiment is also provided with a control system, which can be the control system of the indoor unit or a separate controller can be set up. The controller can control the start or stop of the motor.

[0043] Combined with reference to Figures 1 to 4 As shown, a gravity sensor is provided on the detection end 32.

[0044] Specifically, when the installation end 31 rotates through the internal teeth meshing with the gear, or when the installation end 31 rotates relative to the connecting column 4, the detection end 32 will also rotate accordingly. This will cause the mass block inside the gravity sensor to displace. The gravity sensor is installed on the detection end 32 of the heat exchanger assembly. When the position of the detection end 32 changes, the gravity sensor is used to sense the gravity change caused by the rotation of the installation end 31 to ensure that the detection end 32 is always close to the bottom of the heat exchanger body 2. The signal of the gravity sensor can be fed back to the control system to accurately control the rotation of the installation end 31 and ensure that it accurately reaches the predetermined position.

[0045] In this embodiment, the gravity sensor can not only detect whether the installation end 31 of the heat exchanger assembly rotates in place, but also improve the automation and intelligence level of the whole system. Using the gravity sensor to detect whether the detection end 32 rotates in place can improve the safety and reliability of the heat exchanger assembly. The gravity sensor provides an automatic detection and confirmation mechanism, reducing the errors and omissions of manual operation.

[0046] Combined with reference to Figures 1 to 5 As shown, the refrigerant detection member 3 includes a bracket 301 and a gas sensor 302. One end of the bracket 301 is rotatably connected to the first wall surface 211, and the other end of the bracket 301 is provided with a gas sensor 302, and the gas sensor 302 is close to the bottom of the heat exchanger body 2.

[0047] In this embodiment, the rotatable bracket 301 is provided, so that maintenance personnel can more easily see the state of the gas sensor 302 and perform necessary inspections and maintenance without complex disassembly of the whole heat exchanger assembly. Secondly, the gas sensor 302 is close to the bottom of the heat exchanger body 2, which is the most likely position for refrigerant leakage to accumulate. Setting the gas sensor 302 here can improve the detection accuracy and response speed.

[0048] Refer to the combination of Figures 1 to 6 As shown, a partition 5 is provided in the housing 1. The partition 5 divides the housing 1 into a first chamber 101 and a second chamber 102. The heat exchanger body 2 is installed at the bottom of the housing 1 or on the partition 5.

[0049] Specifically, the partition 5 is installed inside the housing 1 and positioned according to the design requirements to divide the first chamber 101 and the second chamber 102. The installation of the partition 5 needs to ensure its sealing performance and stability to prevent the interference between hot and cold fluids. According to the required installation direction (upward air outlet, downward air outlet, leftward air outlet, rightward air outlet) and air outlet mode, determine the installation position of the heat exchanger body 2. Install the heat exchanger body 2 at the bottom of the housing 1 or on the partition 5 according to the requirements.

[0050] In this embodiment, the heat exchanger body 2 can be installed at the bottom of the housing 1 or on the partition 5 according to the needs, providing flexibility in layout to adapt to different space and design requirements. Moreover, the use of the partition 5 enhances the structural stability of the housing 1 and provides additional support at the same time.

[0051] As a specific implementation manner, when the household unit needs upward air outlet, the heat exchanger body 2 is installed at the bottom of the housing 1. When the household unit needs downward air outlet, the heat exchanger body 2 is installed on the partition 5. In this embodiment, the heat exchanger body 2 is always installed in the second chamber 102. When the household unit needs downward air outlet, the housing 1 rotates 180° counterclockwise or 180° clockwise from the vertical state.

[0052] Refer to the combination of Figures 1 to 6 As shown, a water receiving tray 6 is provided in the housing 1. An installation frame 601 is provided in the second chamber 102. The water receiving tray 6 is arranged on the installation frame 601 or on the partition 5. The heat exchanger body 2 is installed on the water receiving tray 6.

[0053] In this embodiment, the water receiving tray 6 is used to collect the condensed water generated during the heat exchange process. When the heat exchanger is working, the hot fluid releases heat, causing the temperature of the pipe wall in contact with it to drop. The water vapor in the air condenses into water droplets on the pipe wall, and these water droplets will gather in the water receiving tray 6. According to different air outlet modes, the water receiving tray 6 is installed at different positions. The installation frame 601 is optimized according to the specific layout and working conditions of the heat exchanger body 2 to achieve the best hydrodynamic performance and the smallest space occupation. The heat exchanger body 2 and the housing 1 need to be adjusted according to different air outlet modes, and the installation frame 601 is set so that the heat exchanger body 2 can adapt to different installation directions. Whether it is upward air outlet, downward air outlet, leftward air outlet or rightward air outlet, it can effectively collect the condensed water.

[0054] A household unit includes a heat exchanger assembly, and the heat exchanger assembly is the above-mentioned heat exchanger assembly.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model. The above is only the preferred implementation manner of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and variations can be made without departing from the technical principle of the present utility model, and these improvements and variations should also be regarded as within the protection scope of the present utility model.
