Description

Technical Field

[0001] This utility model relates to the field of heat pump outdoor unit technology, specifically a heat pump outdoor unit with waterproof function. Background Technology

[0002] The outdoor unit of a heat pump is one of the core components of a heat pump system. It is mainly responsible for exchanging heat with the external environment and completing the key refrigerant processing steps.

[0003] Nowadays, common heat pump outdoor units in our daily lives include air conditioner outdoor units, air source water heater outdoor units, and ground source heat pump system outdoor units. In air conditioner outdoor units, the compressor compresses the heat absorbed indoors into high-temperature, high-pressure gas, which then exchanges heat with outdoor air through the condenser, completely releasing the heat to the outdoor environment and maintaining a consistently cool indoor environment. In heating mode, it operates in reverse, extracting heat from the low-temperature outdoor air and transferring it indoors for winter heating. Simultaneously, components such as the throttling device and fan within the outdoor unit work together to regulate refrigerant flow and heat dissipation efficiency, ensuring stable system operation.

[0004] However, existing air conditioner outdoor units typically have a ventilation window on the front, directly facing the fan, with a mesh grille to prevent debris from entering and affecting fan operation. However, since these outdoor units are installed outdoors, they are frequently exposed to rain. Rainwater can then seep through the grille into the unit, potentially damaging internal components like the fan. Over time, this water accumulation can further impair the unit's operation. Therefore, we propose a waterproof heat pump outdoor unit to effectively address these drawbacks. Utility Model Content

[0005] The purpose of this utility model is to provide a waterproof heat pump outdoor unit to solve the problems mentioned in the background art.

[0006] This utility model is achieved through the following technical solution: a waterproof heat pump outdoor unit, including a body, a fan cavity inside the body, a ventilation window on the front side of the fan cavity, a waterproof component detachably connected inside the fan cavity, the waterproof component being located near the ventilation window, and a cover plate detachably connected to the top of the body, the cover plate being used to fix the waterproof component inside the fan cavity.

[0007] Optionally, a mounting bracket is fixedly provided inside the fan cavity. The mounting bracket is U-shaped, and its width is equal to the width of the fan cavity. The bottom wall of the mounting bracket is fixedly connected to the bottom wall of the fan cavity, and the waterproof component is detachably connected to the inside of the mounting bracket.

[0008] Optionally, the waterproof component includes a mounting frame that is vertically slidably connected to the inner side of the mounting bracket. A plurality of waterproof fins are fixedly provided on the inner side of the mounting frame. The plurality of waterproof fins are arranged at equal intervals along the height direction of the machine body. The height of the side of the waterproof fins near the ventilation window is lower than the height of the side away from the ventilation window, and the height of the side of the waterproof fins away from the ventilation window is not lower than the height of the waterproof fins located above it near the ventilation window.

[0009] Optionally, a plurality of drainage holes are provided on the bottom wall of the fan cavity, and the plurality of drainage holes are located between the ventilation window and the waterproof component.

[0010] Optionally, the cover plate is hollow inside and has no bottom, and the cover plate is placed on the top of the machine body; when the cover plate is fixed on the top of the machine body, the cover plate presses against the top surface of the waterproof component.

[0011] Optionally, the cover plate is detachably connected to the top of the machine body by a number of screws, and a number of rain shields are fixedly provided on the side of the cover plate. The number of rain shields and the number of screws correspond one-to-one, and the number of rain shields are used to prevent rainwater from entering the machine body through the screw holes.

[0012] Compared with the prior art, this utility model provides a waterproof heat pump outdoor unit, which has the following beneficial effects:

[0013] 1. This utility model provides a waterproof component between the fan and the ventilation window inside the machine body. The mounting bracket and the inclined waterproof fins allow rainwater to be guided between the waterproof component and the ventilation window. Combined with the drainage hole at the bottom of the machine body, rainwater cannot come into contact with the fan and other equipment inside the machine body, and water will not accumulate inside the machine body, thus giving the equipment a certain waterproof function.

[0014] 2. This utility model, by covering the top of the machine body with a cover plate, utilizes the hollow and bottomless structure of the cover plate to prevent rainwater from entering the machine body through the gap between the cover plate and the side wall of the machine body. Furthermore, rain shields are installed at the screw connection positions to surround the screw holes, making it difficult for rainwater to enter the screw holes. This not only reduces the contact between rainwater and screws and prevents the screws from rusting, but also further makes it difficult for rainwater to enter the machine body, thus improving the waterproof effect.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 7 A waterproof heat pump outdoor unit includes a body 1, with a fan cavity 101 inside the body 1. The front side of the fan cavity 101 has a ventilation window 102. The body 1 also contains existing components such as a compressor and condenser, which are not shown in the accompanying drawings. A waterproof component 2 is detachably connected inside the fan cavity 101, located near the ventilation window 102. This waterproof component 2 prevents rainwater passing through the ventilation window 102 from continuing to flow into the body 1, thus preventing rainwater from contacting the internal equipment and affecting the operation of the body 1. A cover plate 3 is detachably connected to the top of the body 1. The cover plate 3 is used to fix the waterproof component 2 inside the fan cavity 101, allowing the user to simultaneously fix the waterproof component 2 when installing the cover plate 3 onto the top of the body 1, and to remove the waterproof component 2 when removing the cover plate 3, so that the user can replace and clean the waterproof component 2.

[0025] Furthermore, a mounting bracket 4 is fixedly installed inside the fan cavity 101. The mounting bracket 4 is U-shaped, and its width is equal to the width of the fan cavity 101. The bottom wall of the mounting bracket 4 is fixedly connected to the bottom wall of the fan cavity 101, and the waterproof component 2 is detachably connected to the inside of the mounting bracket 4. The left and right side walls of the mounting bracket 4 are fixedly connected to the left and right side walls of the fan cavity 101 to ensure there are no gaps between the mounting bracket 4 and the fan cavity 101, preventing water from seeping into the side of the mounting bracket 4 away from the ventilation window 102. This also provides an installation position for the waterproof component 2, facilitating its installation and positioning.

[0026] like Figure 4 As shown, the waterproof component 2 includes a mounting frame 201 that is vertically slidably connected to the inner side of the mounting bracket 4. The top projection shape of the mounting frame 201 is H-shaped, and the top projection shape of the left and right side rods of the mounting bracket 4 is T-shaped. Therefore, the mounting frame 201 and the mounting bracket 4 are compatible. When the mounting frame 201 is connected to the inner side of the mounting bracket 4, the mounting frame 201 and the mounting bracket 4 are sealed together to prevent water penetration. A plurality of waterproof fins 202 are fixedly provided on the inner side of the mounting frame 201. The plurality of waterproof fins 202 are arranged at equal intervals along the height direction of the body 1, and the left and right sidewalls of the waterproof fins 202 are respectively fixedly connected to the left and right inner sidewalls of the mounting frame 201.

[0027] like Figure 3 and Figure 6 As shown, the height of the side of the waterproof fin 202 closest to the ventilation window 102 is lower than the height of the side furthest from the ventilation window 102. Therefore, the waterproof fin 202 is in an inclined state so that when rainwater enters the fan cavity 101, the rainwater is guided by the surface of the waterproof fin 202 to the side closest to the ventilation window 102. Furthermore, the height of the side of several waterproof fins 202 furthest from the ventilation window 102 is not lower than the height of the side of the waterproof fin 202 above it closest to the ventilation window 102, making it difficult for rainwater to enter the fan cavity 101 through the gaps between adjacent waterproof fins 202, further improving the waterproof effect of the waterproof component 2.

[0028] In this embodiment, a plurality of drainage holes 103 are provided on the bottom wall of the fan cavity 101. The plurality of drainage holes 103 are located between the ventilation window 102 and the waterproof component 2, so that water that flows through the waterproof fins 202 to the space between the ventilation window 102 and the waterproof component 2 can be discharged from the drainage holes 103, thereby preventing water from accumulating in the fan cavity 101.

[0029] It should be noted that the cover plate 3 is hollow inside and has no bottom structure. The cover plate 3 is placed on top of the body 1, and the bottom opening of the cover plate 3 is larger than the top opening of the body 1. When the cover plate 3 is installed on top of the body 1, the inner wall of the cover plate 3 fits against the outer wall of the body 1, and the top surface of the body 1 fits against the bottom surface of the waterproof component 2 on the top wall of the cover plate 3, so that rainwater falling on the body 1 and the cover plate 3 will not enter the body 1 from between the body 1 and the cover plate 3. When the cover plate 3 is fixed on top of the body 1, the cover plate 3 presses against the top surface of the waterproof component 2. When the waterproof component 2 is installed on the mounting bracket 4, the top surface of the waterproof component 2 is flush with the top surface of the body 1. Therefore, the top surface of the waterproof component 2 can fit against the bottom surface of the top wall of the cover plate 3, so that the cover plate 3 can fix the waterproof component 2 on the mounting bracket 4, thus completing the installation and fixation of the waterproof component 2.

[0030] Furthermore, the cover plate 3 is detachably connected to the top of the body 1 by several screws. Several rain shields 301 are fixedly provided on the side of the cover plate 3. Each rain shield 301 corresponds to a screw, and the rain shields 301 are used to prevent rainwater from entering the body 1 through the screw holes. Figure 7 As shown, the rain cover 301 blocks the area above and on the left and right sides of the screw and screw hole, making it difficult for rainwater to come into contact with the screw or enter the screw hole, thus making the screw less prone to rusting and further improving the overall waterproof effect of the device.

[0031] The working principle and usage process of this utility model are as follows: First, during installation, the mounting frame 201 is slid vertically onto the inner side of the mounting bracket 4 until the waterproof component 2 can no longer move downwards. Then, the cover plate 3 is placed on top of the body 1. At this time, the cover plate 3 will press the waterproof component 2 against the fan cavity 101, preventing the waterproof component 2 from moving up and down. Then, the cover plate 3 and the body 1 are fixedly connected with screws, so that the waterproof component 2 and the cover plate 3 are fixedly installed, thus enabling the equipment to have waterproof function. When it is necessary to clean or replace the waterproof component 2, the cover plate 3 is removed, and the waterproof component 2 can be taken out from the fan cavity 101. The operation is simple and convenient.
