[0028] See also Figure 1-7 As shown, a water receiving structure includes an installation structure 1 and a water receiving body 2. The installation structure 1 is mounted on an installation surface; the water receiving body 2 is disposed on the installation structure 1. When the installation structure 1 is active, it can drive the water receiving body 2 to move. The water receiving body 2 includes a water receiving space with a water inlet 21. During the movement of the installation structure 1, the water inlet 21 faces upward or diagonally upward. This allows the radar to rotate, with the unit mounted on the installation structure 1, and the radar driving the installation structure 1 to rotate. Furthermore, the installation structure 1 is movably mounted on the installation surface; the water receiving structure of this application is active, and the water in the water receiving tray will not spill out during the movement, and there is no leakage or overflow during rotation. The installation surface can be a wall or other surface suitable for mounting the installation structure 1. That is, the installation structure 1 can be mounted on a wall. When the radar drives the installation structure 1 to rotate, the water receiving body 2, because it is disposed on the installation structure 1, can move with the movement of the installation structure 1, and the water inlet 21 faces upward or diagonally upward throughout the entire movement, so water will not spill out. The installation surface is a vertical plane.
[0029] This application also discloses some embodiments. The mounting structure 1 includes a first surface 11 and a second surface 12 that are interconnected, and there is an angle between the first surface 11 and the second surface 12. A mounting angle is formed at the connection position of the first surface 11 and the second surface 12. The mounting structure 1 is mounted on the mounting surface. The first position is when the first surface 11 is parallel to the mounting surface and the second surface 12 has an angle with the mounting surface. The second position is when the second surface 12 is parallel to the mounting surface and the first surface 11 has an angle with the mounting surface. The mounting structure 1 can rotate at the mounting angle position so that the mounting structure 1 can move between the first position and the second position. During the movement of the mounting structure 1, the water inlet 21 faces upward or diagonally upward. The mounting structure 1 is movable. When the first surface 11 can fit against the mounting surface, there is an angle between the second surface 12 and the mounting surface (because there is an angle between the first surface 11 and the second surface 12). This position is defined as the first position. When the second surface 12 fits against the mounting surface, there is an angle between the first surface 11 and the mounting surface. This position is defined as the second position. The mounting structure 1 can move between the first position and the second position. The angle between the first surface 11 and the second surface 12 can be any angle.
[0030] For example, if the first surface 11 and the second surface 12 are perpendicular to each other, this ensures that the mounting structure 1 can rotate at a 90° angle without leaking or overflowing water and with smooth drainage. If the angle between the first surface 11 and the second surface 12 is acute, this ensures that the mounting structure 1 can rotate at the corresponding obtuse angle without leaking or overflowing water and with smooth drainage; if the angle between the first surface 11 and the second surface 12 is obtuse, this ensures that the mounting structure 1 can rotate at the corresponding acute angle without leaking or overflowing water and with smooth drainage.
[0031] The indoor unit of this application can solve the problem in the prior art where, when the heat exchanger rotates 90°, the direction of the condensate flowing into the water receiving body 2 changes with the rotation of the fan, making it difficult for the water receiving tray to collect the condensate and causing it to overflow easily.
[0032] This application also discloses some embodiments, in which the water receiving body 2 includes side plates; the side plates are connected end to end to enclose and form a water receiving space; one end of the side plate is connected to the mounting structure 1, and the top of the water receiving space forms a water inlet 21; the side plate includes a first plate 231 and a second plate 232 arranged opposite to each other; the first plate 231 is arranged opposite to the first surface 11; the second plate 232 is arranged opposite to the second surface 12; there is an angle between the first plate 231 and the first surface 11, and there is an angle between the second plate 232 and the second surface 12; during the movement of the mounting structure 1, both the first plate 231 and the second plate 232 are inclined upward in the direction near the water inlet 21. The water receiving body 2 may only include each side plate, and each side plate encloses and forms a water receiving groove; that is, the second ends of each side plate are connected to each other to form the bottom of the water receiving groove, and the first end of each side plate is an open end, forming the water inlet 21. It may also include a base plate and side plates; each side plate is connected to the base plate to form a water receiving trough; the base plate forms the bottom of the water receiving trough; the end of the side plate away from the base plate forms a water inlet 21. Regardless of how the installation structure is moved, the water inlet 21 can be facing upwards or diagonally upwards. Each side plate is connected to the base plate, and each side plate can be perpendicular to the base plate or set at an obtuse angle to the base plate to form a water receiving trough with a large opening and a small bottom.
[0033] This application also discloses some embodiments in which the first plate 231 is located above the second plate 232, and the water receiving body 2 further includes an extension 24 connected to the first plate 231. When the mounting structure 1 is in the first position, the extension 24 extends horizontally. The extension 24 is used to install electrical components 3. This can save space and the structure of the bracket for installing electrical components 3. The extension 24 includes an extension plate; the extension plate is parallel to the second surface 12; the extension plate is perpendicular to the first surface 11; the maximum distance between the extension plate and the first surface 11 is d, that is, the maximum distance between the edge of the extension plate away from the first surface 11 and the first surface 11 is d; the maximum distance between the second plate 232 and the second surface 12 is f; by setting d≥20mm and f≥20mm, it is ensured that the water receiving tray is a certain distance from the heat exchanger, so that the part of the heat exchanger inserted into the V-shaped water receiving tray also has airflow.
[0034] This application also discloses some embodiments in which the second plate 232 includes a first portion 2321 and a second portion 2322 connected sequentially in a direction away from the mounting structure 1. The first portion 2321 has a first angle of inclination relative to the second surface 12, and the second portion 2322 has a second angle of inclination relative to the second surface 12, the second angle being greater than the first angle. The first portion 2321 and the second portion 2322 are connected by a connecting structure. The first portion 2321 is used to place the heat exchanger 4; the heat exchanger 4 can be placed on the first portion 2321; the first portion 2321 can provide some support for it.
[0035] This application also discloses some embodiments in which a sealing portion 25 is provided on the inner surface of the second plate 232; the heat exchanger 4 can enter the water receiving space through the water inlet 21 to be installed on the water receiving body 2, and the bottom of the heat exchanger 4 contacts the sealing portion 25. The heat exchanger 4 can be supported by the fixed brackets at both ends, and the sealing portion 25 fits tightly with the heat exchanger 4 to provide a seal and prevent air leakage. The sealing portion 25 is provided on the first part 2321.
[0036] exist Figures 4-5 The present application also includes bolts 91, which are fasteners used to fix the water receiving tray; the fasteners used to fix the heat exchanger fixing bracket 92 are also bolts; the present application also includes nuts 94; the present application also includes fixing blocks 93 welded to the water receiving tray; and riveting nuts 94 are used to fix the water receiving body 2.
[0037] This application also discloses some embodiments in which a water receiving trough 22 is provided at the bottom of the water receiving space, with the opening of the water receiving trough 22 facing the top of the water receiving space. That is, the water receiving trough 22 is provided at the lowest point during the rotation process. This application can meet the requirements of no leakage or overflow during 90° rotation and smooth drainage. The lowest point during the rotation process is the bottom of the water receiving space.
[0038] The surface cooler, i.e., the heat exchanger 4, is embedded in the water receiving space at embedment distances of e and h, respectively. e is set to ≥ 50 mm, and h to ≥ 50 mm. Specifically, in the first position, the maximum vertical distance between the side of the heat exchanger 4 closest to the first plate 231 and the first plate 231 is e; the vertical distance between the heat exchanger 4 and the extension 24 is also e. h is the distance between the side of the heat exchanger 4 closest to the second plate 232 and the edge of the second plate 232. This ensures a certain distance between the water receiving body 2 and the heat exchanger 4, allowing airflow through the portion of the heat exchanger inserted into the V-shaped water receiving tray. A sealing sheet metal is welded onto the water receiving body 2, allowing the surface cooler to adhere to the sheet metal. This provides the heat exchanger 4 with a good heat dissipation channel and rapid collection of condensate, preventing water blowing or overflow during 90° rotation of the heat exchanger 4.
[0039] According to another aspect of this application, an indoor unit is provided, the indoor unit including a water receiving structure, the water receiving structure being the aforementioned water receiving structure.
[0040] This application also discloses some embodiments, in which the indoor unit further includes a heat exchanger 4, and a flow guiding structure 5 is provided on the heat exchanger 4. The flow guiding structure 5 is used to guide the condensate on the heat exchanger 4 into the water receiving space. This can prevent the condensate on the heat exchanger 4 from dripping onto other parts of the indoor unit.
[0041] This application also discloses some embodiments in which the surface of the flow guiding structure 5 is made of a hydrophilic material. The heat exchanger 4 is a surface cooler; the heat exchanger 4 is embedded in the water receiving space of the water receiving body 2, and a sealing sheet metal is welded on the water receiving body 2 so that the surface cooler is attached to the sheet metal. In this way, the surface cooler can have a good heat dissipation channel and can quickly collect condensate, so that the heat exchanger 4 does not blow or overflow during 90° rotation. This application can achieve the following: in the working state, it can rotate 90° with the workbench, i.e., the mounting structure 1, and the water receiving body 2 and the heat exchanger 4 can rotate 90° without leakage or overflow and with smooth drainage.
[0042] The water receiving body 2 is designed in a V-shape (i.e., the bottom of the water receiving body 2 is connected to form the bottom of the water receiving trough, and the top opening forms the water inlet 21). Drainage joints are set at both ends of the first plate 231 and the second plate 232 to prevent water accumulation when the fan plate swings left and right. A water trough is set at the lowest point during rotation, and the water receiving plate is designed with an inclination angle α (0°≤α≤45°). Setting the parameters d and f mentioned above can prevent water overflow. The water receiving body 2 is designed in a V-shape and has an inclination angle, so that the water inlet 21 faces upward or diagonally upward. By setting d≥20mm and f≥20mm, and setting the water trough at the lowest point during rotation, it can meet the requirements of no leakage or overflow during 90° rotation and smooth drainage.
[0043] The water receiving body 2 is provided with a fixing groove, and six rivet nuts are provided in the fixing groove. The water receiving body 2 assembly has a total of eight fixing holes, through which the water receiving body 2 is fixed to the base plate assembly 95. By utilizing the heat exchanger 4, the water receiving body 2, the mounting structure 1, and the tilt angle, this application can rotate without overflowing or blowing water.
[0044] First, the indoor unit of this application mainly consists of a water receiving body 2, an axial fan assembly 6, a fan coil housing 8, a heat exchanger 4, an electrical box component, a switching power supply 31, an air duct assembly 7, and a base plate assembly; the electrical box layout includes electrical components 3; the heat exchanger mounting bracket assembly, etc.; the water receiving structure is fixed to the base plate assembly with bolts; one end of the axial fan assembly 6 is fixed to the water receiving structure, and the other end is fixed to the air duct assembly 7; the air duct assembly 7 is fixed to the heat exchanger 4; the heat exchanger 4 is fixed by the heat exchanger mounting bracket assembly.
[0045] A sealing sheet metal is welded onto the water receiving body 2, allowing the heat exchanger 4 to adhere to it. This provides the heat exchanger 4 with a good heat dissipation channel and allows for rapid collection of condensate, preventing water blowing or overflow during 90° rotation. To ensure uniform distribution of the oncoming air velocity of the heat exchanger 4, the return air surface of the axial fan component is designed to be parallel to the heat exchanger 4, avoiding excessive local air velocity on the surface cooler and preventing water blowing.
[0046] The heat exchanger 4 in this application is a finned heat exchanger. The surface of the finned heat exchanger is made of gold-colored hydrophilic aluminum foil, which is coated with a stable, highly hydrophilic resin. This allows the condensate generated on the aluminum foil surface to be adsorbed from a bead-like form into a film. Testing shows that the initial hydrophilic contact angle θ of the gold-colored hydrophilic aluminum foil is ≤10°, and the hydrophilic contact angle θ during dry-wet cycles is ≤26° (both sides), achieving a 100% wetting rate. Once condensation forms on the aluminum foil surface, it quickly gathers into a water film. When the oncoming wind speed is ≤2.5m / s, the force of the airflow on the condensate is less than the adsorption force of the aluminum foil on the condensate film. Therefore, the condensate is not blown out but instead slides down the aluminum foil and drips into the water collection tray at the bottom of the heat exchanger 4, effectively preventing water blowing problems.
[0047] The axial flow fan blows air outward, causing the condensate on the heat exchanger 4 to be subjected to a force in the same direction as the airflow. When the installation structure 1 is rotated 90°, and the oncoming wind speed is ≤2.5m / s, the force of the airflow on the condensate is less than the adsorption force of the aluminum foil on the condensate film. Therefore, the condensate will not be blown out but will slide down the aluminum foil and drip into the water collection tray at the bottom of the heat exchanger 4, effectively preventing the problem of water blowing. The angle between the bottom plate of the heat exchanger 4 and the indoor unit return air vent is controlled between 35°<θ1<45°.
[0048] Example
[0049] Implementation method: Select a fan with stepless speed regulation and a voltage between 4-9V. During the test, the voltage is gradually increased from 4V until the fan plate blows water. Record the corresponding parameters.

[0051]
[0052] Rated capacity (W): 18000 Rated power (W): 2800 Rated current (A): Nozzle: Indoor #Small: φ50 φ80 φ100

[0054] Example 2: Test data when the included angle θ1 of the heat exchanger is 35°:
[0055]
[0056] Example 3: Test data when the included angle θ1 of the heat exchanger is 45°:
[0057]
[0058] Test data: When the included angle of the heat exchanger is 40°, the fan is set to 8V, and the air volume reaches 1305.26m³ / h, water blowing begins; when the included angle of heat exchanger 4 is 35°, the fan is set to 7V, and the air volume reaches 1030.46m³ / h, water droplets begin to appear; when the included angle of heat exchanger 4 is 45°, the fan is set to 7.2V, and the air volume reaches 1105.66m³ / h, water droplets begin to appear.
[0059] Obviously, the maximum airflow can be achieved without water blowing when the tilt angle θ1 of heat exchanger 4 is between 35° < θ1 < 45°.
