Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, specifically, it relates to the indoor unit of a vertical air conditioner. Background Technology

[0002] In related technologies, the indoor unit of a vertical air conditioner includes a fan and a heat exchanger. Airflow from the environment surrounding the indoor unit enters through the air inlet under the action of the fan and is then sent to the heat exchanger for heat exchange. The heat-exchanged airflow is then sent back into the environment surrounding the indoor unit through the air outlet, thus regulating the ambient air. Because the heat exchanger is close to the air outlet panel, the heat-exchanged airflow flows through the inside of the air outlet panel before exiting, creating convection currents between the inner and outer sides of the panel, resulting in a significant temperature difference between the cold and hot airflows. This convection of cold and hot airflows affects the temperature of the airflow exiting the air outlet, causing a decrease in the air conditioner's heat exchange efficiency. Furthermore, condensation easily forms on the air outlet panel; this condensation dripping onto the inside of the indoor unit affects the safety and lifespan of the internal electrical components. Condensation dripping onto the outside of the indoor unit can also cause ground contamination and damage. Summary of the Invention

[0003] One of the objectives of this utility model is to provide a vertical air conditioner indoor unit that reduces the problems of decreased heat exchange efficiency, reduced safety of electrical components, and pollution caused by condensation due to the convection of cold and hot air currents by installing a baffle plate in the indoor unit.

[0004] To solve the above-mentioned technical problems, the indoor unit of the vertical air conditioner provided by this utility model adopts the following technical solution:

[0005] A vertical air conditioner indoor unit includes a housing, the housing forming a cavity, a heat exchanger being disposed within the cavity, and the housing including an air outlet panel with an air outlet formed thereon; characterized in that a baffle plate is further disposed between the heat exchanger and the air outlet panel, and a heat exchange airflow duct is formed between the baffle plate and the heat exchanger.

[0006] The wind deflector includes:

[0007] A first sidewall, which corresponds to one end of the heat exchanger, extends along the height direction of the heat exchanger;

[0008] A second sidewall is disposed opposite to the first sidewall and corresponds to the other side end of the heat exchanger, and the second sidewall extends along the height direction of the heat exchanger.

[0009] A bottom wall, which connects the first side wall and the second side wall and extends along the height direction of the heat exchanger, and the bottom wall is close to the air outlet panel;

[0010] The bottom wall, the first side wall, and the second side wall form an air cavity with an opening facing the heat exchanger.

[0011] In some embodiments of this application, the bottom wall includes an air guide section, which is an arc-shaped air guide section protruding toward the air outlet panel.

[0012] In some embodiments of this application, the distance between the arc-shaped air guide section and the air outlet panel gradually decreases from the end of the arc-shaped air guide section away from the air outlet to the end of the arc-shaped air guide section closer to the air outlet.

[0013] In some embodiments of this application, the bottom wall further includes:

[0014] The installation section has an installation part formed on the end of the arc-shaped air guide section away from the air outlet, and the baffle plate is installed in the cavity through the installation part.

[0015] In some embodiments of this application, a water receiving component is further provided in the cavity, and the water receiving component is disposed at the bottom of the heat exchanger; the mounting section is assembled onto the water receiving component through the mounting part.

[0016] In some embodiments of this application, the distance between the mounting section and the air outlet panel is greater than the distance between the end of the arc-shaped air guide section away from the air outlet and the air outlet panel;

[0017] The bottom wall also includes:

[0018] A transition section connects the air guide section and the mounting section, and the transition section extends from the mounting section to the air guide section with a sloping structure.

[0019] In some embodiments of this application, the length ratio of the guide section to the length of the air cavity along the air guiding direction is not less than 0.8.

[0020] In some embodiments of this application, the bottom wall further includes:

[0021] The extension section is a planar section. One end of the extension section is connected to the end of the air guide section near the air outlet and extends upward. The other end of the extension section forms an outward flange relative to the air cavity.

[0022] In some embodiments of this application, sidewall flanges that extend outward relative to the air cavity are formed on the first sidewall and the second sidewall, respectively, and an assembly portion is formed on the sidewall flanges, through which the baffle plate is assembled into the cavity.

[0023] In some embodiments of this application, a snap-fit ​​portion is also formed on the outer flange of the side wall, and the wind baffle is snap-fitted into the cavity through the snap-fit ​​portion.

[0024] Compared with the prior art, the advantages and positive effects of this utility model are:

[0025] The indoor unit of this vertical air conditioner features a baffle plate installed within the indoor unit cavity, between the heat exchanger and the air outlet panel. The baffle plate, formed by two side walls and a bottom wall, opens towards the air cavity of the heat exchanger. The bottom wall is close to the air outlet panel. After heat exchange, the airflow, blocked by the baffle plate, passes through the air cavity formed by the baffle plate and the airflow duct between the baffle plate and the heat exchanger before exiting through the air outlet of the air outlet panel. Because the baffle plate is located between the heat exchanger and the air outlet panel, it isolates the flow of the heat-exchanged airflow towards the inside of the air outlet panel. This effectively prevents the convection of cold and hot airflows on the inner and outer sides of the air outlet panel from affecting the temperature change of the heat-exchanged airflow exiting the air outlet, thus preventing a decrease in the heat exchange efficiency of the heat exchanger. Furthermore, it avoids the formation of condensate in the indoor unit due to the convection of cold and hot airflows, which could reduce the safety and lifespan of the internal electrical components, as well as cause pollution and damage to the floor.

[0049] Figures 1 to 6 The image shows an embodiment of the indoor unit of the vertical air conditioner of this utility model. Wherein, Figure 1 and Figure 2 These are a perspective view and an exploded view of this embodiment, respectively. Figure 3 , Figure 4 and Figure 5 This is a perspective view of the wind deflector in this embodiment. Figure 6 This is a side view of the wind deflector.

[0050] like Figure 1 and Figure 2As shown, the indoor unit of this vertical air conditioner includes a first side shell 11, a second side shell 12, a rear panel 13, and an air outlet panel (not shown in the figure, located opposite to the rear panel 13 and connected to the first side shell 11 and the second side shell 12) serving as the front panel. The first side shell 11, the second side shell 12, the rear panel 13, and the air outlet panel together constitute the housing of the indoor unit, forming a cavity 14. An air outlet (not shown in the figure) is formed on the air outlet panel, and an air inlet (not shown in the figure) is formed on the housing. A heat exchanger 2, a water receiving component 3, and a fan 4 are disposed within the cavity 14. Other common structures of indoor units, such as electrical enclosures, are not shown in this embodiment and can be referred to in the prior art. The structure and placement of the heat exchanger 2, the water receiving component 3, and the fan 4 are not limited. In this embodiment, the fan 4 is a centrifugal fan, the heat exchanger 2 is disposed above the fan 4, and the water receiving component 3 is a water receiving tray disposed below the heat exchanger 2.

[0051] In this embodiment, the indoor and outdoor units of the air conditioner work together to regulate the air in the environment where the indoor unit is located. Specifically, in some indoor unit operating modes, such as cooling mode and heating mode, the airflow in the environment where the indoor unit is located enters through the air inlet of the casing under the action of the fan 4 and is sent to the heat exchanger 2 for heat exchange. The airflow after heat exchange is then sent into the environment where the indoor unit is located through the air outlet of the air outlet panel to regulate the temperature of the ambient air.

[0052] In this embodiment, a baffle plate 5 is also provided inside the cavity 14 of the indoor unit. Specifically, the baffle plate 5 is disposed between the heat exchanger 2 and the air outlet panel, and a heat exchange airflow duct is formed between the baffle plate 5 and the heat exchanger 2.

[0053] Combination Figures 3 to 6 As shown, the baffle plate 5 includes a first sidewall 51, a second sidewall 53, and a bottom wall 55. The first sidewall 51 corresponds to one end of the heat exchanger 2 and extends along the height direction of the heat exchanger 2; the second sidewall 53 is disposed opposite to the first sidewall and also corresponds to the other end of the heat exchanger 2, extending along the height direction of the heat exchanger 2. The bottom wall 55 connects the first sidewall 51 and the second sidewall 53, extends along the height direction of the heat exchanger 2, and is close to the air outlet panel. The bottom wall 55, the first sidewall 51, and the second sidewall 53 form an air cavity with an opening facing the heat exchanger 2.

[0054] Specifically, in Figures 1 to 6In the illustrated embodiment, with the air inlet panel as the front and the first side wall 51 as the rear and the panel 13 as the rear, the first side housing 11 is the left side housing, the second side housing 12 is the right side housing, the first side wall 51 of the baffle plate 5 is the right side wall, and the second side wall 53 is the left side wall. The first side wall 51 corresponds to the position of the right end of the heat exchanger 2 and extends along the height direction of the heat exchanger 2, that is, the vertical direction; the second side wall 53 corresponds to the position of the left end of the heat exchanger 2 and extends along the height direction of the heat exchanger 2, that is, the vertical direction. The bottom wall 55 extends from the front edge of the first side wall 51 to the front edge of the second side wall 53 in the left and right directions, and extends from the lower ends of the first side wall 51 and the second side wall 53 to the upper ends of the first side wall 51 and the second side wall 53 in the vertical direction. The bottom wall 55, the first side wall 51, and the second side wall 53 form an air cavity with an opening facing the heat exchanger 2.

[0055] After the baffle 5 is installed in the indoor unit, the airflow of the environment where the indoor unit is located enters through the air inlet of the casing under the action of the fan 4 and is sent to the heat exchanger 2 for heat exchange. After heat exchange, the airflow is blocked by the baffle 5, passes through the air cavity formed by the baffle 5 and the airflow duct between the baffle and the heat exchanger, and is then sent into the environment where the indoor unit is located from the air outlet of the air outlet panel to regulate the temperature of the ambient air. Since the baffle 5 is located between the heat exchanger 2 and the air outlet panel where the air outlet is located, it isolates the flow of the airflow after heat exchange to the inside of the air outlet panel. Since the outside of the air outlet panel is in contact with the ambient airflow, and the airflow after heat exchange is usually airflow with a large temperature difference relative to the ambient airflow, if the cold and hot airflows convect, it will affect the temperature of the airflow sent out from the air outlet, making the temperature of the sent airflow unsuitable for air conditioning, resulting in a decrease in the heat exchange efficiency of the heat exchanger. Furthermore, if cold and hot airflows convect on the air outlet panel, condensation is easily generated. This condensation forms and drips from the inside of the air outlet panel, causing high internal humidity and affecting the safety and lifespan of the electrical components inside the indoor unit. Condensation also forms and drips onto the ground from the outside of the air outlet panel, causing soiling and damage. Therefore, by utilizing the wind deflector 5, the convection of cold and hot airflows on both sides of the air outlet panel effectively prevents changes in the temperature of the heat exchange airflow exiting the air outlet, thus avoiding a decrease in the heat exchanger's efficiency. Moreover, it also prevents the formation of condensation in the indoor unit due to the convection of cold and hot airflows, thus avoiding a decrease in the safety and lifespan of the electrical components inside the indoor unit, as well as soiling and damaging the ground.

[0056] See also Figures 1 to 6The bottom wall 55 includes an air guide section 551, which is an arc-shaped air guide section protruding towards the air outlet panel. The arc-shaped air guide section 551 serves two purposes: firstly, by guiding the heat exchange airflow using the arc-shaped air guide section, airflow noise can be reduced, wind resistance can be decreased, airflow loss can be reduced, and airflow efficiency can be improved; secondly, the arc-shaped air guide section protruding towards the air outlet panel can increase the air cavity space, increase the airflow volume, and further reduce airflow loss and airflow noise.

[0057] In some other embodiments, the lower end of the arc-shaped air guide section 551 is away from the air outlet, and the upper end is close to the air outlet. The distance between the arc-shaped air guide section 551 and the air outlet panel gradually decreases from the lower end to the upper end of the air guide section 551. This causes the air cavity of the baffle plate 5 to gradually contract from bottom to top. The lower end of the air cavity is close to the fan 4, which easily generates wind resistance and noise. By setting the air guide section 551, the space at the lower end of the air cavity is made large enough to minimize wind resistance, reduce airflow loss, and reduce airflow noise. By setting the air guide section 551, the space at the upper end of the air cavity is reduced, which increases the flow velocity of the heat exchanger airflow flowing out from the upper end near the air outlet, ensuring that the heat exchanger airflow is delivered from the air outlet at a higher wind speed and improving air delivery efficiency.

[0058] To ensure stable assembly of the baffle 5 and avoid significant noise and airflow loss due to unstable assembly, the bottom wall 55 also includes a mounting section 552. This mounting section 552 is located near the end of the air guide section 551 away from the air outlet, i.e., at the lower end of the air guide section 551. A mounting part 5521 is formed on the mounting section 552, through which the baffle 5 is mounted in the cavity 14.

[0059] In some embodiments, the mounting section 552 is located at the lowest point of the entire bottom wall 55, which facilitates improved assembly convenience and stability. Multiple mounting holes are formed on the water receiving component 3, and the mounting portion 5521 includes multiple mounting holes. The multiple mounting holes on the mounting section 552 cooperate with the multiple mounting holes on the water receiving component 3, and the baffle 5 is installed to the water receiving component 3 using screws. By placing the mounting section 552 at the lowest point of the bottom wall 55, the baffle 5 is assembled to the water receiving component 3 via the mounting section 552. Since the water receiving component 3 is typically located below the heat exchanger 2, the air cavity of the baffle 5 can be positioned close to the lower end of the heat exchanger 2. This facilitates rapid and complete noise reduction and wind resistance reduction of the airflow after heat exchange starting from the lower end of the heat exchanger 2, improving the effectiveness of the baffle application.

[0060] To facilitate assembly, the distance between the mounting section 552 and the air outlet panel is greater than the distance between the lower end of the guide section 551 (away from the air outlet) and the air outlet panel, thus providing a larger operating space between the mounting section 552 and the air outlet panel for easier assembly. To reduce wind resistance, in this structure where the distance between the mounting section 552 and the air outlet panel is greater than the distance between the lower end of the guide section 551 (away from the air outlet) and the air outlet panel, the bottom wall 55 also includes a transition section 553 connecting the guide section 551 and the mounting section 552. The transition section 553 extends from the mounting section 552 to the guide section 551 with a sloping structure. By providing the sloping structure of the transition section 553, in addition to connecting the mounting section 552 and the guide section 551 (which are not on the same plane), it also provides a guide surface for airflow buffering, further reducing wind resistance and noise. The sloping structure of the transition section 553 can be a sloping plane or a sloping arc surface; this embodiment does not specifically limit the sloping structure.

[0061] To achieve stable assembly of the wind deflector 5 and avoid significant noise and airflow loss due to unstable assembly, a first sidewall outward flange 52 is formed on the first sidewall 51 of the wind deflector 5, facing outward relative to the air cavity, and a first mounting portion 521 is formed on the first sidewall outward flange 52; a second sidewall outward flange 54 is formed on the second sidewall 53 of the wind deflector 5, facing outward relative to the air cavity, and a second mounting portion 541 is formed on the second sidewall outward flange 54. The wind deflector 5 is assembled into the cavity 14 via the first mounting portion 521 and the second mounting portion 541. In some embodiments, the first mounting portion 521 and the second mounting portion 541 each include multiple mounting holes. Using screws and the multiple mounting holes on the first mounting portion 521 and the second mounting portion 541, the wind deflector 5 is installed to the housing and / or the frame, bracket, or other structures in the housing, thereby achieving a stable assembly of the wind deflector 5 within the cavity 14.

[0062] To achieve accurate and rapid assembly of the wind deflector 5, a first snap-fit ​​portion 522 is formed on the outer flange 52 of the first side wall, and a second snap-fit ​​portion 542 is formed on the outer flange 54 of the second side wall. During assembly, the wind deflector 5 is pre-positioned by the snap-fit ​​engagement of the first snap-fit ​​portion 522 and the second snap-fit ​​portion 542 with the corresponding snap-fit ​​portions inside the cavity. After positioning, it is then assembled and installed through the assembly part, installation part, etc., improving assembly efficiency. In some embodiments, the first snap-fit ​​portion 522 may include a plurality of claws, and similarly, the second snap-fit ​​portion 542 may include a plurality of claws. The housing of the indoor unit and / or the frame, bracket, and other structures in the housing are provided with slots that engage with the claws. Of course, the first snap-fit ​​portion 522 and the second snap-fit ​​portion 542 may also adopt other structures that can achieve snap-fit ​​assembly, and this embodiment does not limit this.

[0063] To improve the structural strength of the baffle plate 5, the bottom wall 55 also includes an extension section 554. This extension section 554 is a planar section, one end of which, i.e., the lower end of the extension section 554, connects to the upper end of the air guide section 551 near the air outlet and extends upward. The other end of the extension section 554, i.e., its upper end, forms an extension section outward flange 56 relative to the air cavity. That is, the extension section outward flange 56 extends from the top of the extension section 554 toward the air outlet panel. The extension section 554 can be a straight planar section or an inclined planar section; the extension section outward flange 56 can be a planar section to reduce the space occupied by the indoor unit in the limited vertical direction.

[0064] like Figure 6 As shown, along the airflow direction of the air cavity, i.e., the up-down direction, the length of the entire air cavity is L1, including the length of the air cavity enclosed by all sections of the bottom wall; the length of the airflow guide section is L2. Furthermore, the ratio of the length of the windbreak section to the length of the entire air cavity is not less than 0.8, i.e., L2 / L1≥0.8. This design allows the air cavity formed by the airflow guide section to be as large as possible. The air cavity formed by the airflow guide section is a key air cavity for reducing wind resistance and noise, thereby maximizing the reduction of wind resistance and noise and increasing the airflow volume.

[0065] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
