Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and more specifically, to a wall-mounted air conditioner indoor unit and an air conditioner. Background Technology

[0002] In wall-mounted air conditioner indoor units, the air outlet is usually located at the junction of the lower part of the front surface and the front part of the lower surface, and the width of the air outlet is usually a few centimeters to about ten centimeters. However, if the air conditioner has a zero-wind function, or is called a diffuser function, no wind or gentle wind function, then a diffuser panel needs to be installed to block or basically block the air outlet of the air conditioner.

[0003] The air diffuser panel has many small-diameter ventilation holes. When the airflow from the air conditioner encounters the solid part of the diffuser panel, it is dispersed by the solid part, and the airflow can only flow out through the ventilation holes. Because the diameter of the ventilation holes is very small, usually only a few millimeters in size, the airflow passing through the ventilation holes mixes with the air after flowing a short distance on the leeward side of the diffuser panel, thus not forming a noticeable airflow. When the user is indoors, it is difficult for the user to feel the cold air blowing on them.

[0004] Due to the size limitations of the air outlet of the air conditioner, the size of the diffuser is usually similar to that of the air outlet. This results in a small total area of ​​the diffuser holes and a small total cross-sectional area of ​​the airflow channel through the diffuser, which in turn leads to a small airflow. In other words, the airflow under the zero-wind-feel function is small, making it difficult to reach the required temperature quickly. Utility Model Content

[0005] The first objective of this utility model is to provide a wall-mounted air conditioner indoor unit to solve the technical problem of low air volume in existing wall-mounted air conditioner indoor units under zero-wind-feel function.

[0006] The first aspect of this utility model provides a wall-mounted air conditioner indoor unit, including a main housing and a front housing disposed on the front side of the main housing. An air outlet cavity is formed inside the front housing, and a heat exchange cavity is formed at the rear of the main housing. A fan cavity is disposed inside the main housing, and an air conditioning fan for conveying airflow from the heat exchange cavity to the air outlet cavity is disposed in the fan cavity. An air inlet is provided in the main housing, a front diffuser hole is provided in the front wall panel of the front housing along the thickness direction of the front wall panel, a side diffuser hole is provided in the side wall panel of the front housing along the thickness direction of the side wall panel, and a lower air outlet is provided on the bottom surface of the front housing. A lower air guide plate is installed on the lower air outlet in a closable manner.

[0007] The beneficial effects of this wall-mounted air conditioner indoor unit are:

[0008] When the indoor unit of the wall-mounted air conditioner is running in zero-wind mode, the lower air guide plate is closed, and the air conditioner fan delivers the airflow from the heat exchange chamber to the air outlet chamber of the casing. By setting a front air diffuser on the front wall panel and a side air diffuser on the side wall panel, airflow is blown out from both the front and side walls of the casing in zero-wind mode, increasing the air volume in zero-wind mode.

[0009] Therefore, it can be seen that this wall-mounted air conditioner indoor unit uses both the front and side panels of the casing as the air outlet surface in zero-wind-feel mode. Compared with traditional wall-mounted air conditioner indoor units that only use the air outlet as the air outlet surface in zero-wind-feel mode, it can effectively increase the air outlet area in zero-wind-feel mode. This allows for the installation of air diffusers over a larger area, so that a larger air volume can be obtained without changing the density, size, and other conditions of the air diffusers. This improves the speed of temperature regulation, allowing the indoor space to reach the required temperature more quickly after the zero-wind-feel mode is activated.

[0010] Furthermore, the main housing is provided with a middle partition and a rear partition arranged sequentially in a front-to-back direction. The air outlet cavity is located between the middle partition and the front shell, the fan cavity is located between the middle partition and the rear partition, and the air conditioning fan is installed on the middle partition. The heat exchange cavity is located in the area of ​​the rear partition away from the middle partition. The aforementioned middle partition and rear partition not only effectively separate the air outlet cavity, fan cavity, and heat exchange cavity, but also prevent condensation from forming on the front shell.

[0011] Furthermore, the heat exchange chamber is equipped with an indoor heat exchanger, which is a V-shaped heat exchanger with its opening facing forward and opposite to the air conditioning fan. The V-shaped heat exchanger increases its distribution area within the heat exchange chamber. By positioning its opening opposite the air conditioning fan, it ensures that air exchanges heat with the V-shaped heat exchanger before being drawn away by the fan, thus preventing uneven heating or cooling of the airflow delivered by the air conditioning fan.

[0012] Furthermore, the heat exchange chamber is equipped with a water receiving tray, which is located below the V-shaped heat exchanger. This water receiving tray not only collects the condensate generated during the operation of the V-shaped heat exchanger, but also provides at least partial support for the V-shaped heat exchanger, ensuring its operational stability.

[0013] Furthermore, the drip tray and the rear partition are an integral structure. By making the drip tray and the rear partition an integral structure, on the one hand, the number of parts of the wall-mounted air conditioner indoor unit can be reduced, improving assembly efficiency; on the other hand, it can also ensure the sealing of the connection between the drip tray and the rear partition, preventing condensate from leaking out from the joint between the drip tray and the rear partition.

[0014] Furthermore, the air inlet includes an upper air inlet and a lower air inlet. The upper air inlet is located at the top of the main unit housing, and the lower air inlet is located at the bottom of the main unit housing. This arrangement allows external airflow to enter simultaneously from both the upper air inlet at the top of the main unit housing and the lower air inlet at the bottom of the main unit housing during operation of the wall-mounted air conditioner indoor unit, thereby increasing the air intake volume.

[0015] Furthermore, the number of air conditioning fans is multiple, and these multiple air conditioning fans are arranged at intervals along the left and right directions of the wall-mounted air conditioner indoor unit. This arrangement ensures, on the one hand, the uniformity of airflow from the wall-mounted air conditioner indoor unit in the left and right directions, ensuring airflow to both the left and right areas of the indoor unit regardless of whether it is operating in zero-wind-feel mode or normal mode. On the other hand, it also ensures that, during zero-wind-feel mode operation, the airflow from the air outlet cavity can reach the side diffuser vents in a timely manner, thus guaranteeing the reliability of the airflow delivered through the side diffuser vents.

[0016] Furthermore, the side diffusers are arranged in multiple rows, spaced apart along the front-to-back direction, with any two adjacent rows staggered. This arrangement ensures that the airflow from any two adjacent rows of side diffusers has no gaps in the vertical direction; that is, the airflow from the side diffusers is continuous in the vertical direction. This arrangement guarantees the uniformity of airflow from the side diffusers in the vertical direction.

[0017] Furthermore, the side air diffuser is a strip-shaped hole. This design increases the air outlet area of ​​the side air diffuser, allowing the wall-mounted air conditioner indoor unit to maintain air volume even in zero-wind mode, so that the indoor space can reach the required temperature more quickly in zero-wind mode.

[0018] The second objective of this utility model is to provide an air conditioner that solves the technical problem of low air volume in the indoor unit of existing wall-mounted air conditioners under the zero-wind-feel function.

[0019] The air conditioner provided in the second aspect of this utility model includes an outdoor unit and the aforementioned wall-mounted indoor unit, wherein the wall-mounted indoor unit is connected to the outdoor unit via a refrigerant connection pipe.

[0020] By installing the aforementioned wall-mounted air conditioner indoor unit in the air conditioner, the air conditioner accordingly possesses all the advantages of the aforementioned wall-mounted air conditioner indoor unit, which will not be elaborated upon here. Attached Figure Description

[0031] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0033] Example 1:

[0034] Figure 1 This is one of the structural schematic diagrams of the wall-mounted air conditioner indoor unit provided in this embodiment when the lower air guide plate 310 is closed; Figure 2 This is the second schematic diagram of the wall-mounted air conditioner indoor unit provided in this embodiment when the lower air guide plate 310 is closed. Figure 1 and Figure 2 As shown, this embodiment provides a wall-mounted air conditioner indoor unit, including a main unit housing 100 and a front panel 200 disposed on the front side of the main unit housing 100.

[0035] Figure 3 This is a lateral cross-sectional view of the wall-mounted air conditioner indoor unit provided in this embodiment when the lower air guide plate 310 is closed; Figure 4 This is a top sectional view of the wall-mounted air conditioner indoor unit in zero-wind-feel mode provided in this embodiment. Figure 3 and Figure 4 As shown, an air outlet cavity 210 is formed inside the front shell 200, a heat exchange cavity 110 is formed at the rear of the main unit housing 100, and a fan cavity 120 is provided inside the main unit housing 100. An air conditioning fan 140 is provided in the fan cavity 120 for conveying the airflow of the heat exchange cavity 110 to the air outlet cavity 210.

[0036] Figure 5 This is a schematic diagram of the structure of the wall-mounted air conditioner indoor unit provided in this embodiment when the lower air guide plate 310 is open; Figure 6 This is a partial structural cross-sectional view of the wall-mounted air conditioner indoor unit provided in this embodiment. (See attached image.) Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the main housing 100 has an air inlet 130, the front wall of the front housing 200 has a front air diffuser 220 that extends through the thickness of the front wall, the side wall of the front housing 200 has a side air diffuser 230 that extends through the thickness of the side wall, and the bottom surface of the front housing 200 has a lower air outlet 240, and a lower air guide plate 310 is installed on the lower air outlet 240 in an openable and closable manner.

[0037] When the indoor unit of the wall-mounted air conditioner is running in zero-wind mode, the lower air guide plate 310 is closed, and the air conditioner fan 140 delivers the airflow from the heat exchange chamber 110 to the air outlet chamber 210 of the casing 200. By setting a front air diffuser 220 on the front wall panel of the casing 200 and a side air diffuser 230 on the side wall panel of the casing 200, airflow is blown out from both the front wall panel and the side wall panel of the casing 200 in zero-wind mode, increasing the air volume in zero-wind mode.

[0038] For example, taking a 1-horsepower or 1.5-horsepower air conditioner as an example, the width of the air outlet of a traditional wall-mounted air conditioner indoor unit is usually 5 to 8 centimeters, rarely exceeding 10 centimeters. Therefore, the area where the air vent of a traditional wall-mounted air conditioner indoor unit can be set is this width multiplied by the length of the air outlet. This is because even if the edge of the air outlet is close to the side wall of the front surface of the air conditioner, transmission and drive components are still needed for the rotation of the traditional air guide plate, which still occupies space in the left and right directions. In this embodiment, the wall-mounted air conditioner indoor unit utilizes both the front and side panels of the casing 200 as the air outlet surface in zero-wind-feel mode. The width of the area where the air diffusers are set can reach the overall height of the front panel of the wall-mounted air conditioner indoor unit. Moreover, since side air diffusers 230 can also be set on the side panels, the length of this area can also exceed the length of the wall-mounted air conditioner indoor unit. That is, the sum of the length of the wall-mounted air conditioner indoor unit and the front and rear dimensions of the area where the air diffusers are set on the side panels. Therefore, air diffusers can be set over a larger area, thereby effectively increasing the air outlet area in zero-wind-feel mode. This allows for a larger air volume to be obtained without changing the density, size, and other conditions of the air diffusers, thereby improving the speed of temperature adjustment. This enables the indoor space to reach the required temperature more quickly after the zero-wind-feel mode is activated.

[0039] It should be noted that when the indoor unit of the wall-mounted air conditioner is running in normal mode, i.e., in non-zero wind mode, the lower air guide plate 310 can be opened. At this time, although the air outlet cavity 210 is provided with a front diffuser 220 and a side diffuser 230, the airflow may be discharged from the aforementioned front diffuser 220 and side diffuser 230. However, since the resistance of the lower air outlet 240 is less than or even much less than the sum of the resistances of the airflow only exiting from the front diffuser 220 and the side diffuser 230 after the lower air outlet 240 is opened, the airflow is mainly or almost entirely discharged from the air outlet cavity 210 through the lower air outlet 240, and only a very small amount of airflow may be discharged from the front diffuser 220 and the side diffuser 230.

[0040] The type of air conditioning fan 140 can be an axial flow fan, a mixed flow fan, or a vortex fan, with the axis of these fans set along the front-to-back direction. Of course, in another implementation, the air conditioning fan 140 can also be a cross-flow fan, with the axis of the cross-flow fan in the left-to-right direction. The internal air outlet 151 on the partition plate 150 described later can be rectangular or rounded rectangle, and the length of the rectangle or rounded rectangle is similar to the length of the impeller of the cross-flow fan.

[0041] In this embodiment, all ventilation holes are circular. Of course, in other implementations, the ventilation holes can be other shapes, such as rectangles, rhombuses, or rounded rectangles / rounded rhombuses. The ventilation holes can be arranged in columns, with each column's horizontal projection located in an adjacent column. More specifically, the ventilation holes can be located at the midpoint between two adjacent ventilation holes. Furthermore, three adjacent ventilation holes can be arranged in an equilateral triangle.

[0042] It should also be noted that in this embodiment, the lower air guide plate 310 is rotatably mounted on the front shell 200, and the lower air guide plate 310 can be driven to rotate by the drive mechanism 320 to open or close. How to utilize the drive mechanism 320 to drive the rotation of the lower air guide plate 310 is something that those skilled in the art can obtain from existing technology; this embodiment does not improve upon this, and therefore will not be elaborated further.

[0043] Please continue to refer to Figure 3 , Figure 4 and Figure 6 In this embodiment, the main unit housing 100 is provided with a middle partition 150 and a rear partition 160 arranged sequentially in the front-to-back direction. The air outlet cavity 210 is located between the middle partition 150 and the front shell 200, the fan cavity 120 is located between the middle partition 150 and the rear partition 160, and the air conditioning fan 140 is installed on the middle partition 150. The heat exchange cavity 110 is located in the area of ​​the rear partition 160 away from the middle partition 150.

[0044] The fan cavity 120 is formed by the area between the middle partition 150 and the rear partition 160, so that the air outlet cavity 210 and the heat exchange cavity 110 are separated by the area between the middle partition 150 and the rear partition 160. Thus, when the indoor unit of the wall-mounted air conditioner is running in cooling mode, the cold air in the heat exchange cavity 110 transfers the cooling capacity to the rear partition 160. However, since the air in the fan cavity 120 does not transfer the cooling capacity to the middle partition 150 along with the air in the heat exchange cavity 110, the temperature of the middle partition 150 and the air outlet cavity 210 in front of it is relatively high, and the air is less likely to condense on these surfaces. Furthermore, when the air conditioner fan 140 is running, the cooler air after heat exchange with the indoor heat exchanger 170 only circulates inside the air conditioner fan 140, and very little new cold air is added into the fan cavity 120. Therefore, the air in the fan cavity 120 is relatively still, and the temperature is distributed in a gradient. The closer to the air conditioner fan 140 and the closer to the rear partition 160, the lower the air temperature, while the closer to the middle partition 150, the higher the air temperature. The air that may produce condensation is not all the air in the fan cavity 120, so the total amount of air available for condensation is also relatively small, which helps to slow down or even eliminate the formation of condensation.

[0045] In other words, the aforementioned middle partition 150 and rear partition 160 not only effectively separate the air outlet cavity 210, the fan cavity 120 and the heat exchange cavity 110, but also prevent condensation from forming on the surface shell 200.

[0046] Please continue to refer to Figure 3 and Figure 6 In this embodiment, the heat exchange chamber 110 is provided with an indoor heat exchanger 170, which is a V-shaped heat exchanger. The opening of the V-shaped heat exchanger faces forward and is opposite to the air conditioning fan 140.

[0047] The V-shaped heat exchanger increases its distribution area inside the heat exchange chamber 110. By setting the opening of the V-shaped heat exchanger to be opposite to the air conditioning fan 140, the air can exchange heat with the V-shaped heat exchanger before being drawn away by the air conditioning fan 140, thus avoiding uneven heating and cooling of the airflow sent out by the air conditioning fan 140.

[0048] In this embodiment, a V-shaped heat exchanger is embedded at the rear end of the air conditioning fan 140, and the rear partition 160 gradually arches from its edge toward the air conditioning fan 140.

[0049] Please continue to refer to Figure 3 and Figure 6 In this embodiment, the heat exchange chamber 110 is provided with a water receiving tray 180, specifically, the water receiving tray 180 is located directly below the bottom of the V-shaped heat exchanger.

[0050] The aforementioned water receiving tray 180 not only serves to collect the condensate generated during the operation of the V-shaped heat exchanger, but also provides support for the installation of the V-shaped heat exchanger, thereby ensuring its operational stability.

[0051] It should be noted that the V-shaped heat exchanger can be supported not only by the water receiving pan 180, but also by other components installed in the main housing 100. As for the other components of the main housing 100 supporting the water receiving pan 180, this is known technology in the art and will not be described further in this application.

[0052] Please continue to refer to Figure 3 and Figure 6 In this embodiment, the water receiving tray 180 and the rear partition 160 are an integral structure.

[0053] By making the drip tray 180 and the rear partition 160 an integrated structure, on the one hand, the number of parts of the wall-mounted air conditioner indoor unit can be reduced and the assembly efficiency can be improved; on the other hand, the sealing of the connection between the drip tray 180 and the rear partition 160 can be ensured, preventing condensate from leaking out from the joint between the drip tray 180 and the rear partition 160.

[0054] Please continue to refer to Figure 6 In this embodiment, the air inlet 130 opened on the main unit housing 100 includes an upper air inlet 131 and a lower air inlet 132, wherein the upper air inlet 131 is opened on the top of the main unit housing 100 and the lower air inlet 132 is opened on the bottom surface of the main unit housing 100.

[0055] This configuration allows external airflow to enter simultaneously from the upper air inlet 131 at the top of the main unit housing 100 and the lower air inlet 132 at the bottom of the main unit housing 100 during operation of the indoor unit of the wall-mounted air conditioner, thereby increasing the air intake volume.

[0056] In this embodiment, there are two air conditioning fans 140, which are arranged at intervals along the left and right sides of the wall-mounted air conditioning indoor unit.

[0057] This design ensures uniform airflow from the wall-mounted air conditioner indoor unit in both left and right directions. Whether in zero-wind-feel mode or normal mode, airflow is delivered to both sides of the indoor unit, reducing the distance between the air conditioner fan 140 and the end of the indoor heat exchanger 170, thus maximizing the length of the heat exchanger 170. Furthermore, because the internal air outlet 151 is close to the side wall of the casing 200, it ensures that the airflow from the outlet cavity 210 reaches the side diffuser 230 promptly during zero-wind-feel mode, guaranteeing the reliability of the airflow delivered through the side diffuser 230. Specifically, the internal air outlet 151 is located on the partition 150, with one internal air outlet 151 corresponding to each air conditioner fan 140.

[0058] Understandably, the number of air conditioning fans 140 can be selected based on the dimensions of the wall-mounted air conditioner indoor unit along the left and right directions. Specifically, when the dimensions of the wall-mounted air conditioner indoor unit along the left and right directions are large, a larger number of air conditioning fans 140 should be selected.

[0059] Please continue to refer to Figure 3 In this embodiment, the side ventilation holes 230 are arranged in multiple rows, and the multiple rows of side ventilation holes 230 are arranged at intervals along the front-back direction, and any two adjacent rows of side ventilation holes 230 are staggered.

[0060] By staggering any two adjacent rows of side diffusers 230, the airflow blowing out from any two adjacent rows of side diffusers 230 has no gap in the height direction; that is, the airflow blowing out from the side diffusers 230 is continuous in the height direction. This arrangement ensures the uniformity of airflow from the side diffusers 230 in the vertical direction.

[0061] Please continue to refer to Figure 3 In this embodiment, the side ventilation hole 230 is a strip-shaped hole.

[0062] By setting the side air diffuser 230 as a strip-shaped hole, the air outlet area of ​​the side air diffuser 230 can be increased, so that the indoor unit of the wall-mounted air conditioner can take into account the air volume in the zero-wind mode, so that the indoor space can reach the required temperature more quickly in the zero-wind mode.

[0063] In this embodiment, the front air diffuser 220 is a circular hole. Of course, in other implementations, the front air diffuser 220 can be other shapes, such as rectangles, rhombuses, or rounded rectangles or rounded rhombuses. Similarly, the front air diffusers 220 can also be arranged in columns, with each column of front air diffusers 220 projected horizontally into an adjacent column. More specifically, the space between two adjacent front air diffusers 220 can be located at the midpoint between two adjacent front air diffusers 220. Furthermore, three adjacent front air diffusers 220 can be arranged in an equilateral triangle.
