Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically providing a chassis for a portable air conditioner and a portable air conditioner. Background Technology

[0002] Portable air conditioners are portable air conditioning devices that integrate cooling and dehumidification functions. They have a chassis structure with water storage at the bottom, and use a water jet to throw condensate onto the heat exchanger surface to achieve evaporative cooling. This structural design allows the device to operate independently without an external drain pipe.

[0003] However, when the water jet rotates at high speed, in a traditional single-layer heat exchanger layout, water splashes from the gaps in the heat exchanger. Since the heat exchanger is located close to the outer casing, the water jet easily splashes water onto the outside of the machine, affecting the user experience.

[0004] Therefore, there is a need in the art for a chassis for a portable air conditioner and a portable air conditioner to solve the above-mentioned technical problems. Utility Model Content

[0005] The present invention aims to solve the above-mentioned technical problem, namely, the problem that in the prior art, water is easily thrown off the outside of the water-spraying machine, which affects the user experience.

[0006] In a first aspect, this utility model provides a chassis for a portable air conditioner, the chassis comprising a body, a heat exchanger, a water jet, and a water-blocking structure.

[0007] The heat exchanger includes a double-layer heat exchange plate and a single-layer heat exchange plate, and a water storage tank is provided at the bottom of the interlayer between the double-layer heat exchange plate and the single-layer heat exchange plate.

[0008] The water-pumping wheel is installed inside the water storage tank.

[0009] The water-blocking structure includes water-blocking ribs, which are disposed on the side wall of the main body near the single-layer heat exchange plate.

[0010] In the specific embodiment of the chassis for the portable air conditioner described above, the water-retaining rib extends vertically along the inner surface of the side wall of the body.

[0011] The height of the water-blocking rib is 1 / 5 to 1 / 2 of the height of the heat exchanger.

[0012] In the specific embodiment of the chassis for the portable air conditioner described above, the main body has an L-shaped mounting space formed by the rear vertical wall and the first side vertical wall.

[0013] The single-layer heat exchange plate is arranged along the back vertical wall and the first side vertical wall.

[0014] The double-layer heat exchange plate is attached to the single-layer heat exchange plate on one side of the vertical wall on the back, and the double-layer heat exchange plate is spaced apart from the single-layer heat exchange plate on one side of the first side vertical wall to form a sandwich space.

[0015] In the specific embodiment of the chassis for the portable air conditioner described above, the water-blocking ribs are respectively disposed on the back vertical wall and the first side vertical wall.

[0016] In the specific embodiment of the chassis for the aforementioned portable air conditioner, the water-blocking structure further includes a water-guiding slope.

[0017] The water guide slope is disposed within the water storage tank and is disposed in the radial direction of the water-pumping wheel.

[0018] In the specific embodiment of the chassis for the aforementioned portable air conditioner, the water guide slope has a water guide incline.

[0019] The water-guiding slope forms an angle of 15° to 30° with the horizontal plane.

[0020] In the specific embodiment of the chassis for the portable air conditioner described above, the chassis also includes a power cord.

[0021] The body also has a second side vertical wall, which is connected to the back vertical wall and opposite to the first side vertical wall.

[0022] A cable routing groove is provided on the second side vertical wall, and the cable routing groove connects the second side vertical wall to the back vertical wall.

[0023] The power cord is installed inside the cable tray.

[0024] In the specific embodiment of the chassis for the portable air conditioner described above, the wiring channel includes a fixing channel and a positioning channel, and the power cord includes a positioning component and a wire clamp.

[0025] The positioning element is adapted to the positioning groove, and the positioning element is disposed within the positioning groove.

[0026] The wire clamp is embedded in the fixing groove to press the power cord into the cable routing groove.

[0027] In the specific embodiment of the chassis for the portable air conditioner described above, the chassis further includes a motor.

[0028] The motor drives the water jet to rotate, so as to throw the condensate in the water storage tank onto the surface of the heat exchanger.

[0029] By adopting the above technical solution, this utility model provides a chassis for a portable air conditioner. The chassis includes a body, a heat exchanger, a water jet, and a water-blocking structure. The heat exchanger includes a double-layer heat exchange plate and a single-layer heat exchange plate. The single-layer heat exchange plate is located near the edge of the body. A water storage tank is provided at the bottom of the interlayer between the double-layer and single-layer heat exchange plates. The water jet is located within the water storage tank. The water-blocking structure includes water-blocking ribs located near the side wall of the single-layer heat exchange plate body. Based on the above structural configuration, the chassis provided by this utility model uses water-blocking ribs to block water splashes on one side of the single-layer heat exchange plate, while the other side is equipped with a double-layer heat exchange plate, forming a natural anti-splash structure, effectively solving the problem of water splashing from the chassis when the water jet rotates.

[0030] Furthermore, the chassis for portable air conditioners provided by this utility model limits the height of the water-repellent ribs. Since the lower part of the heat exchanger is the concentrated area where water splashes occur, increasing the height of the side wall of the body by increasing the water-repellent ribs can effectively improve the chassis's ability to prevent water splashing.

[0031] Furthermore, the chassis for a portable air conditioner provided by this invention defines the placement of the heat exchanger. A single-layer heat exchange plate is located at the edge of the main body, while a double-layer heat exchange plate is located in the middle of the main body. This allows for the placement of both single-layer and double-layer heat exchange plates within a limited space, ensuring a compact structure. Additionally, the L-shaped heat exchanger transforms the traditional linear heat exchanger into a right-angle bend structure, perfectly adapting to the corner space layout of portable air conditioners and improving heat exchange efficiency.

[0032] Furthermore, the chassis for portable air conditioners provided by this utility model defines water-blocking ribs respectively set on the back vertical wall and the first side vertical wall. Since the single-layer heat exchange plate is set along the back vertical wall and the first side vertical wall, the two places on the back vertical wall and the first side vertical wall are the serious areas of water splashing. Setting water-blocking ribs at these two places can further improve the water blocking effect.

[0033] Furthermore, the chassis for a portable air conditioner provided by this utility model defines a water guide slope, and the water-blocking slope is set in the radial direction of the water impeller, so that the water droplets in this direction are reflected in a specified direction, thereby guiding them back into the water storage tank to reduce splashing to the outside of the heat exchanger.

[0034] Furthermore, the chassis for a portable air conditioner provided by this invention defines a water-guiding slope, and by defining the inclination angle of the water-guiding slope, a better water-guiding effect is achieved.

[0035] Furthermore, the chassis for the portable air conditioner provided by this utility model specifies that the power cord is installed in the cable tray so that the power cord can be routed out from the back of the machine, making it convenient for users to use.

[0036] Furthermore, the chassis for portable air conditioners provided by this utility model defines a fixing groove and a positioning groove. During the installation of the power cord, the positioning component is placed in the positioning groove, which facilitates the operation of the assembly personnel. After the power cord is installed, the power cord is fixed in the cable tray by the wire clamp, which can improve the connection strength of the power cord and meet the pull-out force test.

[0037] Furthermore, the chassis for the portable air conditioner provided by this utility model includes a motor for controlling the rotation of the water pump.

[0038] On the other hand, the present invention also provides a portable air conditioner, which includes a chassis for portable air conditioners as described in the above embodiments. Attached Figure Description

[0049] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although this specific embodiment is described in conjunction with the application of the chassis in a portable air conditioner, the chassis of the present invention can obviously also be used in other scenarios. Such changes in application scenarios do not deviate from the basic principles of the present invention and fall within the scope of protection of the present invention.

[0050] In this disclosure, the terms "upper," "lower," "inner," "middle," "outer," "front," and "rear," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for better description of the embodiments of this disclosure and their implementations, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to require them to be constructed and operated in a specific orientation. Furthermore, some of the aforementioned terms may be used to indicate other meanings besides orientation or positional relationship; for example, the term "upper" may in some cases indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in the embodiments of this disclosure according to the specific circumstances.

[0051] Portable air conditioners are portable air conditioning devices that integrate cooling and dehumidification functions. They feature a chassis with a water storage function at the bottom, and use a water jet to spray condensate onto the heat exchanger surface for evaporative cooling. This design allows the device to operate independently without an external drain pipe. However, when the water jet rotates at high speed, in a traditional single-layer heat exchanger layout, water splashes from the gaps in the heat exchanger. Because the heat exchanger is located close to the outer casing, the water jet tends to splash onto the outside of the machine, affecting the user experience.

[0052] Therefore, there is a need in the art for a chassis for a portable air conditioner and a portable air conditioner to solve the above-mentioned technical problems.

[0053] First, see Figure 1 , Figure 1 This is a top view of the chassis for a portable air conditioner provided by this utility model, as shown below. Figure 1As shown, this utility model provides a chassis for a portable air conditioner. The chassis includes a body 1, a heat exchanger 2, a water jet 3, and a water-blocking structure 4. The heat exchanger 2 includes a double-layer heat exchange plate 21 and a single-layer heat exchange plate 22. A water storage tank 23 is provided at the bottom of the interlayer between the double-layer heat exchange plate 21 and the single-layer heat exchange plate 22. The water jet 3 is disposed in the water storage tank 23. The water-blocking structure 4 includes a water-blocking rib 41, which is disposed on the side wall of the body 1 near the single-layer heat exchange plate 22. Based on the above structural configuration, the chassis provided by this utility model uses the water-blocking rib 41 to block water splashes on one side of the single-layer heat exchange plate 22, and the double-layer heat exchange plate 21 is provided on the other side to form a natural anti-splash structure, effectively solving the problem of water splashing from the chassis when the water jet 3 rotates.

[0054] It is understandable that, since the heat exchanger 2 is usually located close to the edge of the body 1, the space between the heat exchanger 2 and the edge of the body 1 is insufficient to install a double-layer heat exchange plate 21. To solve the water splashing problem on this side, a single-layer heat exchange plate 22 is installed on this side, and a water baffle 41 is installed on the side wall of the body 1. However, the side of the heat exchanger 2 closer to the center of the body 1 has more space, and a double-layer heat exchange plate 21 can be directly installed on this side to achieve a natural anti-splashing effect.

[0055] In this preferred embodiment, the water-repellent rib 41 extends vertically along the inner surface of the side wall of the body 1, and the height of the water-repellent rib 41 is 1 / 5 to 1 / 2 of the height of the heat exchanger 2. This proposal limits the height of the water-repellent rib 41. Since the lower part of the heat exchanger 2 is the concentrated area where water splashing occurs, increasing the height of the side wall of the body 1 by increasing the water-repellent rib 41 can effectively improve the anti-splash capability of the chassis.

[0056] In this preferred embodiment, the body 1 has an L-shaped installation space formed by a back vertical wall 11 and a first side vertical wall 12. A single-layer heat exchange plate 22 is arranged along the back vertical wall 11 and the first side vertical wall 12. A double-layer heat exchange plate 21 is attached to the single-layer heat exchange plate 22 on one side of the back vertical wall 11, and the double-layer heat exchange plate 21 is spaced apart from the single-layer heat exchange plate 22 on one side of the first side vertical wall 12 to form a sandwich space. Based on the above structural configuration, this utility model limits the installation position of the heat exchanger 2. The single-layer heat exchange plate 22 is located at the edge of the body 1, and the double-layer heat exchange plate 21 is located in the middle of the body 1. Therefore, the single-layer heat exchange plate 22 and the double-layer heat exchange plate 21 can be accommodated in a limited space, ensuring a compact structure. In addition, the L-shaped heat exchanger 2 transforms the traditional straight heat exchanger into a bend structure, perfectly adapting to the corner space layout of portable air conditioners and improving heat exchange efficiency.

[0057] In this preferred embodiment, the body 1 is a cuboid, meaning that the back vertical wall 11 and the first side vertical wall 12 are arranged perpendicularly to each other, thus making the L-shaped heat exchanger 2 a right-angle bend structure. In other embodiments, the body 1 can also have other structures, and the L-shaped heat exchanger 2 can be arranged along two adjacent sides of the body 1.

[0058] In this preferred embodiment, the water-blocking ribs 41 are respectively disposed on the back vertical wall 11 and the first side vertical wall 12. Since the single-layer heat exchange plate 22 is disposed along the back vertical wall 11 and the first side vertical wall 12, the two locations of the back vertical wall 11 and the first side vertical wall 12 are the areas where water splashes are severe. Disposing the water-blocking ribs 41 at these two locations can further improve the water-blocking effect.

[0059] In this preferred embodiment, the water-blocking structure 4 further includes a water-guiding slope 42, which is disposed in the water storage tank 23 and in the radial direction of the water jet 3, so that the water droplets in this direction are reflected in a specified direction and guided back into the water storage tank 23 to reduce splashing to the outside of the heat exchanger 2.

[0060] In this preferred embodiment, the water guiding slope 42 has a water guiding incline, which forms an inclination angle of 15° to 30° with the horizontal plane. By limiting the inclination angle of the water guiding incline, a better guiding effect can be achieved. It is understood that if the inclination angle of the water guiding incline is too large, the height of the water guiding slope 42 will be too high, which may obstruct the structure of the heat exchanger 2 and affect the heat exchange efficiency of the heat exchanger 2. Conversely, if the inclination angle of the water guiding incline is too small, the water flow velocity will be low and water accumulation may easily occur. Those skilled in the art can select the inclination angle of the water guiding incline according to the actual situation.

[0061] In this preferred embodiment, see Figure 2 , Figure 2 This is a front view of the chassis for a portable air conditioner provided by this utility model. Figure 2 As shown, the chassis for a portable air conditioner provided by this utility model also includes a power cord 5. (See also...) Figure 3 , Figure 3 This is a schematic diagram of the overall structure of the chassis for a portable air conditioner provided by this utility model. Figure 3 As shown, the main body 1 also has a second side vertical wall 13, which is connected to the back vertical wall 11 and opposite to the first side vertical wall 12. A cable routing groove 131 is provided on the second side vertical wall, connecting the second side vertical wall 13 to the back vertical wall 11. The power cable 5 is disposed in the cable routing groove 131 so that the power cable 5 can exit from the back of the machine, which is convenient for users. In the prior art, the traditional straight cable routing method cannot adapt to the layout of irregular heat exchangers, thus forcing the use of side cable routing, which makes it inconvenient for users. At the same time, the solution also has serious waterproof defects and a high insulation failure rate.

[0062] In this preferred embodiment, combined with Figure 2 and Figure 3 The cable tray 131 includes a fixing tray 132 and a positioning tray 133. The power cord 5 includes a positioning element 51 and a wire clamp 52. The positioning element 51 is adapted to the positioning tray 133 and is set in the positioning tray 133. The wire clamp 52 is embedded in the fixing tray 132 to press the power cord 5 into the cable tray 131. During the installation of the power cord 5, the positioning element 51 is set in the positioning tray 133, which facilitates the operation of the assembly personnel. After the power cord 5 is installed, the wire clamp 52 fixes the power cord 5 in the cable tray 131, which can improve the connection strength of the power cord 5 and meet the pull-out force test.

[0063] In this preferred embodiment, see Figure 1 The chassis for the portable air conditioner provided by this utility model also includes a motor 6, which drives the water jet 3 to rotate, so as to splash the condensate in the water storage tank 23 onto the surface of the heat exchanger 2. It should be noted that this utility model does not impose any restrictions on the specific structure and installation position of the motor 6, and technicians can set it according to actual usage requirements.

[0064] On the other hand, this utility model also provides a portable air conditioner, which includes a chassis as described in the above embodiment. Based on the above structural configuration, the portable air conditioner provided by this utility model uses a water-blocking rib 41 to block water splashes on one side of the single-layer heat exchange plate 22, and a double-layer heat exchange plate 21 is provided on the other side to form a natural anti-splash structure, effectively solving the problem of water splashing from the chassis when the water wheel 3 rotates.

[0065] It should be noted that the above embodiments are only used to illustrate the principle of this utility model and are not intended to limit the scope of protection of this utility model. Without departing from the principle of this utility model, those skilled in the art can adjust the above structure so that this utility model can be applied to more specific application scenarios.

[0066] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
