Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to a compact wall-mounted indoor unit for ships. Background Technology

[0002] The indoor unit is part of an air conditioning system, typically including a casing, cross-flow fan, fan, air outlet, and heat exchanger. The main function of the indoor unit is to exchange heat with indoor air through the internal heat exchanger and fan, thereby achieving a cooling or heating effect. Indoor units come in various types, selectable based on installation method and usage environment. For example, there are wall-mounted, ceiling-mounted, and floor-standing models. Currently, in the use of household indoor units installed on compact ships, we have found that condensation often spills out in the turbulent environment of a ship, causing environmental pollution. Furthermore, the common installation methods used on ships result in unstable installations, posing a risk of the indoor unit falling.

[0003] Therefore, it is necessary to design a compact wall-mounted indoor unit for ships to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a compact wall-mounted indoor unit for ships.

[0005] The technical solution of this utility model is: a compact wall-mounted indoor unit for ships, including a shell and a cross-flow fan and heat exchanger disposed inside the shell; the inner bottom of the shell is a water collection tray for receiving condensate; the bottom surface of the water collection tray is set in a concave arc shape, and both ends of the water collection tray are provided with drain outlets communicating with the inside of the water collection tray at the lowest point of the concave arc; the drain outlets are connected to the outside of the ship through drain pipes.

[0006] The heat exchanger is a copper tube and copper fin heat exchanger.

[0007] The bottom surface of the water receiving tray is provided with a hydrophobic coating.

[0008] The outlet end of the drain is equipped with a check valve to prevent backflow.

[0009] The back of the hull is provided with shock-absorbing pads on the ship's wall; each of the four corners of the back of the hull is provided with connecting lugs, which are fixedly connected to the ship's wall by bolts passing through the shock-absorbing pads.

[0010] The cross-flow impeller is made of titanium alloy and its surface is treated to prevent salt spray.

[0011] It also includes a guide air duct located at the top of the housing; the air duct has a rotatable louvered air outlet with an adjustment angle range of 0°-120°.

[0012] The air inlet of the air guide duct is equipped with an air intake filter.

[0013] By adopting the above technical solution, this utility model has the following beneficial effects: the bottom surface of the water receiving tray is set in a concave arc shape, and water outlets are provided at both ends, so that water can be drained from both ends, ensuring that condensate can be discharged, thereby preventing condensate from spilling out and polluting the environment.

[0020] (Example 1)

[0021] See Figures 1 to 3 This embodiment discloses a compact wall-mounted indoor unit for ships, comprising a housing 1 and a cross-flow fan 2 and a heat exchanger 3 disposed within the housing 1. The inner bottom of the housing 1 has a water collection tray 4 for receiving condensate. The bottom surface of the water collection tray 4 is concave, and both ends of the water collection tray 4, corresponding to the lowest point of the concave arc, have drain outlets 5 communicating with the interior of the water collection tray 4. The drain outlets 5 are connected to the outside of the ship via drain pipes. This embodiment integrates the cross-flow fan 2 and the heat exchanger 3 inside the housing 1, resulting in a compact structure suitable for the limited space of ship cabins. The cross-flow fan 2 provides stable airflow, and the heat exchanger 3 achieves efficient heat exchange, ensuring rapid adjustment of the indoor temperature. Simultaneously, the concave arc-shaped water collection tray 4 effectively collects condensate, and the drain outlets 5 at both ends are located at the lowest points, ensuring rapid drainage of condensate and preventing water accumulation that could lead to corrosion or bacterial growth. The drain pipe connects to the outside of the ship, preventing condensate stagnation from affecting equipment operation.

[0022] Furthermore, the heat exchanger 3 is a copper tube and copper fin heat exchanger 3, which has excellent thermal conductivity and corrosion resistance, and is suitable for shipboard environments with high humidity and high salt spray, thereby improving heat exchange efficiency and extending service life.

[0023] Furthermore, the bottom surface of the water tray 4 is provided with a hydrophobic coating to reduce condensation adhesion, accelerate drainage speed, reduce the risk of scale and microbial growth, and improve the cleanliness and durability of the water tray 4.

[0024] Furthermore, the outlet end of the drain 5 is equipped with a backflow prevention check valve to prevent condensate from flowing back due to ship rocking or changes in external water pressure, thus ensuring the stability and reliability of the drainage system.

[0025] Furthermore, the back of the shell 1 is provided with shock-absorbing pads against the ship's wall; each of the four corners of the back of the shell 1 is provided with connecting lugs, which are fixedly connected to the ship's wall by bolts passing through the shock-absorbing pads. The shock-absorbing pads buffer the vibrations and impacts during ship navigation, reducing noise; the four-point bolt fixing enhances structural stability, prevents equipment from loosening or falling off, and adapts to the complex operating conditions of the ship.

[0026] Furthermore, the cross-flow wind turbine 2 is made of titanium alloy and its surface is treated with anti-salt spray to further resist seawater corrosion and ensure that the wind turbine can operate reliably for a long time in harsh environments.

[0027] The compact shipboard wall-mounted indoor unit of this embodiment also includes a guide air duct located at the top of the housing 1; the air duct has a rotatable louvered air outlet with an adjustment angle range of 0°-120°. The louvered air outlet can flexibly adjust the air delivery angle to achieve precise airflow guidance, meet the temperature requirements of different cabin areas, and improve comfort.

[0028] Furthermore, the air inlet of the air guide duct has an air intake filter 6, which intercepts impurities such as salt particles and dust, protects the internal impeller and heat exchanger 3 from contamination, reduces maintenance frequency, and extends the service life of the equipment.

[0029] The compact wall-mounted indoor unit for ships in this embodiment achieves stable cooling, long-lasting durability, and comfortable air supply in ship cabin environments through its compact corrosion-resistant structure, efficient drainage system, salt spray resistance design, and intelligent air supply control.

[0030] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
