Description

Technical Field

[0001] The utility model relates to the field of household electrical appliances, in particular to an indoor unit of an air conditioner. Background Art

[0002] With the development of society and the continuous improvement of people's living standards, various air conditioning devices have become one of the indispensable electrical devices in people's daily lives. Various air conditioning devices can help people reach a comfortable temperature when the ambient temperature is too high or too low. Current air conditioning devices mainly include various types of air conditioners and fans.

[0003] Air conditioners can be categorized as either integrated or split-type units. Split-type units consist of both an indoor unit and an outdoor unit. As integrated interior design becomes more prevalent, expectations for indoor units are also rising. They require not only aesthetically pleasing design and superior performance, but also compatibility with home decor requirements. Embedded indoor units not only offer the functionality of standard units but also blend seamlessly with the cabinet design. Embedding the indoor unit within the cabinet creates a cohesive, aesthetically pleasing design.

[0004] When existing air conditioner indoor units are embedded for use, it is necessary to first lay out a drain pipe, then install the air conditioner indoor unit into a cabinet, and finally connect the air conditioner indoor unit to the drain pipe. When connecting the drain pipe, the drain pipe can easily bend to form a water trap, which reduces the service life of the drain pipe and increases the risk of condensation water leakage. In addition, when existing air conditioner indoor units are embedded for use, the air intake method similar to that of traditional wall-mounted air conditioner indoor units is not applicable. Because traditional wall-mounted air conditioner indoor units generally take in air through the air inlet on the top, after the air conditioner indoor unit is embedded in the cabinet, the top will be blocked by the cabinet, affecting the air intake. In addition, the reduced air intake will cause the indoor heat exchanger of the air conditioner indoor unit to be unable to fully exchange heat, which is prone to freezing and affecting the normal operation of the indoor heat exchanger.

[0027] This embodiment provides an air conditioner indoor unit, which can reduce the redundant length of the drainage pipe, avoid bending of the drainage pipe and shortening its service life, and improve the user experience. Figure 1 1 is a schematic diagram of the overall structure of an air conditioner indoor unit 100 according to an embodiment of the present invention. Figure 2 This is a schematic diagram showing that the total length between the water inlet 136 of the connecting pipe 131 and the water outlet 147 of the drain pipe 140 of the air conditioner indoor unit 100 according to one embodiment of the present invention is a first length. Figure 3 This is a schematic diagram showing that the total length between the water inlet 136 of the connecting pipe 131 and the water outlet 147 of the drain pipe 140 of the air conditioner indoor unit 100 according to one embodiment of the present invention is a second length. Figure 4 1 is a schematic diagram showing that the total length between the water inlet 136 of the connecting pipe 131 and the water outlet 147 of the drain pipe 140 of the air conditioner indoor unit 100 according to another embodiment of the present invention is a third length. Figure 5 1 is a schematic diagram showing that the total length between the water inlet 136 of the connecting pipe 131 and the water outlet 147 of the drain pipe 140 of the air conditioner indoor unit 100 according to another embodiment of the present invention is a fourth length. Figure 6 FIG is a side sectional view of the housing 110 of the air conditioner indoor unit 100 according to one embodiment of the present invention. Figures 1 to 6 As shown, the air conditioner indoor unit 100 of this embodiment may generally include: a housing 110 , a water receiving tray 130 and a drain pipe 140 .

[0028] An indoor heat exchanger 111 is disposed within the housing 110. The indoor heat exchanger 111 can be configured to exchange heat with air entering the housing 110. Specifically, when the air conditioner indoor unit 100 operates in cooling mode, the air heated by the indoor heat exchanger 111 becomes cold air, which can be delivered to the indoor environment to lower the ambient temperature. When the air conditioner indoor unit 100 operates in heating mode, the air heated by the indoor heat exchanger 111 becomes hot air, which can be delivered to the indoor environment to raise the ambient temperature.

[0029] The water receiving pan 130 is arranged below the indoor heat exchanger 111 and is configured to receive condensed water at the indoor heat exchanger 111. The water receiving pan 130 is provided with a connecting pipe 131. The drain pipe 140 can be snap-connected with the connecting pipe 131 so that the condensed water in the water receiving pan 130 can flow into the drain pipe 140 through the connecting pipe 131. Specifically, during the cooling process of the air conditioner indoor unit 100, when the surface temperature of the indoor heat exchanger 111 is lower than the dew point temperature of the indoor air, the water vapor in the air is caused to condense here when it is cooled, forming liquid condensed water. After the condensed water flows into the water receiving pan 130, it can flow to the drain pipe 140 through the connecting pipe 131 of the water receiving pan 130, and finally be discharged to the outside through the drain pipe 140.

[0030] When the existing air conditioner indoor unit is embedded for use, it is necessary to first arrange the drain pipe, then install the air conditioner indoor unit into the cabinet, and finally connect the air conditioner indoor unit to the drain pipe. When connecting the drain pipe, the drain pipe can easily bend to form a water trap, which reduces the service life of the drain pipe and increases the risk of condensation water leakage. The air conditioner indoor unit 100 of this embodiment, by adjusting the clamping position of the drain pipe 140 and the connecting pipe 131, changes the total length between the water inlet 136 of the connecting pipe 131 and the water outlet 147 of the drain pipe 140, mainly to reduce the total length. The reduction in total length can actually reduce the length of the movable part of the drain pipe 140, that is, it can reduce the redundant length of the drain pipe 140, avoid the drain pipe 140 from bending and shortening its service life, and improve the user experience.

[0031] In a specific embodiment, the drain pipe 140 includes a connector 141 and a water pipe 142, with one end of the connector 141 being snap-connected to the connecting pipe 131 and the other end being connected to the water pipe 142. In other words, one end of the connector 141 of the drain pipe 140 can be snap-connected to the connecting pipe 131 of the water receiving tray 130. Furthermore, the other end of the connector 141 can be snap-connected to the water pipe 142 to achieve a quick connection. In other embodiments, the drain pipe 140 may not be provided with the connector 141, but only with the water pipe 142, and the connecting pipe 131 of the water receiving tray 130 can be directly connected to the water pipe 142 of the drain pipe 140.

[0032] In a preferred embodiment, Figure 2 and Figure 3 As shown, the connecting tube 131 may be provided with a first buckle 133 at the front and a second buckle 134 at the rear, and the connecting member 141 may be provided with a first slot 143. When the first slot 143 is engaged with the first buckle 133, the total length is a first length; when the first slot 143 is engaged with the second buckle 134, the total length is a second length, wherein the first length is less than the second length.

[0033] It should be noted that Figure 2 and Figure 3 The connecting member 141 shown is provided with a first slot 143 at the front and a fourth slot 146 at the rear, but in fact the total length is changed by adjusting the first slot 143 at the front to engage with the first buckle 133 and the second buckle 134. The fourth slot 146 is provided at the rear of the connecting member 141 to Figure 2 When the first card slot 143 is engaged with the first card buckle 133, the second card buckle 134 can be exposed in the fourth card slot 146, avoiding interference between the second card buckle 134 and the inner wall of the connecting member 141, thereby effectively ensuring the connection reliability between the connecting member 141 and the connecting tube 131.

[0034] In another preferred embodiment, Figure 4 and Figure 5 As shown, the connecting tube 131 can be provided with a third latch 135, and the connecting member 141 can be provided with a second latch slot 144 at the front and a third latch slot 145 at the rear. Specifically, the third latch 135 can be located slightly behind the connecting tube 131. Furthermore, when the second latch slot 144 and the third latch 135 are engaged, the total length is a third length; when the third latch slot 145 and the third latch 135 are engaged, the total length is a fourth length, where the third length is greater than the fourth length.

[0035] Figures 2 to 5 The illustrations all show a case where one end of the connector 141 of the drain pipe 140 is clipped into the connecting pipe 131 of the water receiving tray 130. In other embodiments, where the drain pipe 140 is not provided with the connector 141 but only with the water pipe 142, the connecting pipe 131 of the water receiving tray 130 can be directly connected to the water pipe 142 of the drain pipe 140. In this case, the relevant clipping groove originally provided on the connector 141 can be transferred to the water pipe 142.

[0036] In a specific embodiment, Figures 2 to 5 As shown, the water tray 130 may include a skeleton body 132 configured to support the indoor heat exchanger 111. In other words, the water tray 130 in this embodiment serves a dual purpose: it can both support the indoor heat exchanger 111 and collect condensed water from the indoor heat exchanger 111. Furthermore, the connecting pipe 131 is located on either side of the skeleton body 132. Figures 2 to 5 The connecting pipes 131 shown are all located on the right side of the skeleton body 132 .

[0037] In a preferred embodiment, the skeleton body 132 gradually decreases from the side away from the connecting pipe 131 to the side of the connecting pipe 131, so that the condensed water gathers at the connecting pipe 131 and flows out. Figures 2 to 5The connecting pipe 131 is shown as being located to the right of the skeleton body 132, meaning that the skeleton body 132 gradually descends from left to right. It should be noted that the slope of the gradually descending skeleton body 132 is relatively small to prevent an excessively large slope from affecting the stability of the support for the indoor heat exchanger 111. This small slope is sufficient to ensure that condensed water converges at the connecting pipe 131, flows through the water inlet 136 of the connecting pipe 131, and ultimately flows out through the water outlet 147 of the water pipe 142 of the drain pipe 140.

[0038] In one specific embodiment, the skeleton body 132 and the connecting pipe 131 are integrally formed. Furthermore, the water tray 130 can be made of ABS (Acrylonitrile Butadiene Styrene) or HIPS (High Impact Polystyrene), which offer high strength, good toughness, and ease of processing. The connecting piece 141 can be made of POM (Polyoxymethylene), which offers advantages such as high strength, rigidity, and good elasticity.

[0039] In a specific embodiment, Figure 1 As shown, the air conditioner indoor unit 100 may further include a panel 120 disposed on the front side of the housing 110. The panel 120 has an air inlet 121 on its upper portion and an air outlet 122 on its lower portion. Air enters the housing 110 through the air inlet 121, exchanges heat in the indoor heat exchanger 111, and is then discharged to the indoor environment through the air outlet 122. When the air conditioner indoor unit 100 is installed, a drain pipe 140 must be arranged before the unit 100 is installed in a cabinet and finally connected to the drain pipe 140. After removing the panel 120, the air conditioner indoor unit 100 of this embodiment has a gap on the lower right side of the interior of the unit 100, making it easier for workers or users to reach in and connect the unit 100 to the drain pipe 140.

[0040] In a specific embodiment, Figure 6 As shown, the interior of the housing 110 defines a first channel 115 and a second channel 116. The air inlet of the first channel 115 is higher than the air inlet of the second channel 116. In fact, the air inlet of the first channel 115 and the air inlet of the second channel 116 are both part of the air inlet 121. In other words, the air entering the interior of the housing 110 through the air inlet 121 flows partially through the first channel 115 and partially through the second channel 116.

[0041] In addition, an indoor heat exchanger 111 is provided in each of the first channel 115 and the second channel 116. In a specific embodiment, Figure 6As shown, the indoor heat exchanger 111 is arranged in sections and includes a front heat exchanger 117, a middle heat exchanger 118 and a rear heat exchanger 119 from front to back. The front heat exchanger 117 and the middle heat exchanger 118 are located in the second channel 116, and the rear heat exchanger 119 is located in the first channel 115.

[0042] Depend on Figure 6 It can be seen that the front heat exchanger 117 and the middle heat exchanger 118 are closer to the air inlet 121 than the rear heat exchanger 119. Generally, most of the air entering the housing 110 through the air inlet 121 flows to the front heat exchanger 117 and the middle heat exchanger 118, while less air flows through the rear heat exchanger 119. This may lead to insufficient overall air volume and, in turn, cause adverse phenomena such as icing on the indoor heat exchanger 111. However, this embodiment provides two channels within the housing 110 and makes the air intake of the first channel 115 stronger than that of the second channel 116. This allows more air to enter the first channel 115 through the air inlet 121 and exchange heat through the rear heat exchanger 119 in the first channel 115, effectively solving the problem of icing on the indoor heat exchanger 111 caused by insufficient air volume.

[0043] In a specific embodiment, Figure 6 As shown, a fan 112 may be provided below the indoor heat exchanger 111, configured to blow the air heated by the indoor heat exchanger 111 toward the air outlet 122. More specifically, as Figure 6 As shown, the front heat exchanger 117 can be basically set in a vertical state, the middle heat exchanger 118 can be set gradually higher from front to back, and the rear heat exchanger 119 can be set gradually lowered from front to back, so that the front heat exchanger 117, the middle heat exchanger 118 and the rear heat exchanger 119 jointly define a space below which the fan 112 is accommodated.

[0044] Furthermore, the airflow into the first channel 115 can be stronger than that into the second channel 116 by specifically configuring the fan 112. For example, the suction port of the fan 112 can be adjusted to be more directed toward the rear heat exchanger 119, so that the airflow into the first channel 115 is stronger than that into the second channel 116. Alternatively, in other embodiments, the fan 112 can be adjusted in other ways to achieve a stronger airflow into the first channel 115 than into the second channel 116.

[0045] The air conditioner indoor unit 100 can be arranged in a cabinet having a forward opening, with the panel 120 facing forward. Specifically, a storage space can be defined within the cabinet, and the air conditioner indoor unit 100 can be arranged in the storage space. In a specific embodiment, the air conditioner indoor unit 100 can be placed directly in the storage space. In other embodiments, the air conditioner indoor unit 100 can also be fixed to the cabinet in some way, for example, by fixing the housing 110 of the air conditioner indoor unit 100 to the cabinet to improve overall stability.

[0046] In one specific embodiment, the cabinet is provided with a rear wall, and the water pipe 142 is fixed to the rear wall. This ensures the installation stability of the drain pipe 140 and prevents the drain pipe 140 from easily moving and causing water leakage. Furthermore, the water pipe 142 of the drain pipe 140 can pass through the gap provided in the lower right corner of the cabinet, allowing condensed water to flow out of the water outlet 147 of the drain pipe 140 and be discharged to the outside. In another specific embodiment, the cabinet can be provided without a rear wall, and the water pipe 142 can be directly fixed to the wall, which can also prevent the drain pipe 140 from easily moving.

[0047] It's important to note that the current air intake system for flush-mounted air conditioner indoor units is not suitable. This is because traditional wall-mounted units typically draw air through a top air inlet. When the unit is embedded in a cabinet, the top is blocked by the cabinet, limiting air flow. Furthermore, the reduced air intake prevents the indoor heat exchanger from fully exchanging heat, leading to icing and affecting its proper function.

[0048] The air conditioner indoor unit 100 of this embodiment adopts a front air intake and front air outlet method, and adopts a dual-channel solution inside the shell 110, which can fully guide the air entering the shell 110 through the air inlet 121 to the rear heat exchanger 119 at the rear, avoiding the freezing phenomenon of the indoor heat exchanger 111 caused by insufficient air volume. At the same time, the front air intake and front air outlet are achieved without being restricted by the cabinet. In a preferred embodiment, a filter 128 can be provided at the air inlet 121, so that the air entering the shell 110 can be preliminarily filtered, thereby improving the cleanliness of the air flowing through the process and also improving the air quality of the indoor environment.

[0049] The air conditioner indoor unit 100 of this embodiment is designed as a two-part, front and rear section consisting of a panel 120 and a housing 110. This facilitates both assembly and maintenance. Specifically, during assembly, the rear section of the housing 110 and its associated components can be installed into a cabinet first, followed by the front section, including the panel 120 and its associated components. This allows for easy maintenance of the rear section of the housing 110 while the front section, including the panel 120, is open. Furthermore, after the panel 120 and housing 110 are assembled, the rear section of the housing 110 is not visible and is not a cosmetic component, thus reducing requirements and significantly reducing costs.

[0050] Specifically, the relevant structure of the front panel 120 mainly includes the filter 128 mentioned above, and can also include a display panel box, wherein the display panel can be used to display relevant information of the air conditioner indoor unit 100, such as operating mode, set temperature, etc. The relevant structure of the rear shell 110 mainly includes the indoor heat exchanger 111 and fan 112 mentioned above, wherein the fan 112 can also be provided with a corresponding fan motor, configured to drive the fan 112 to rotate. And the air supply speed of the air conditioner indoor unit 100 can be adjusted by adjusting the speed of the fan motor driving the fan 112. In addition, an electrical box can be provided above the indoor heat exchanger 111 to accommodate electronic control components such as a computer board to control the air conditioner indoor unit 100.

[0051] When the air conditioner indoor unit 100 operates in cooling mode, the air heated by the indoor heat exchanger 111 is cold air, which is sent to the indoor environment through the air outlet 122 to reduce the temperature of the indoor environment, making the user feel cool. When the air conditioner indoor unit 100 operates in heating mode, the air heated by the indoor heat exchanger 111 is hot air, which is sent to the indoor environment through the air outlet 122 to increase the temperature of the indoor environment, making the user feel warm.

[0052] In a specific embodiment, the air conditioner indoor unit 100 can activate the cooling mode or the heating mode after receiving a user's activation trigger signal. More specifically, the activation trigger signal can be received from the user via a display device, a voice device, a remote control, or a mobile terminal associated with the air conditioner indoor unit 100. The mobile terminal can be a portable smart device, such as a smartphone or tablet computer.

[0053] Fan 112 delivers the air heated by indoor heat exchanger 111 to the indoor environment through outlet 122. Fans 112 can primarily include centrifugal, crossflow, and axial flow types. In centrifugal fans, the air is subjected to centrifugal force, creating a vacuum at the center of the impeller. The inhaled air is deflected 90° at the impeller inlet and enters the flow channel formed by the blades, where it gains kinetic and pressure energy. The airflow ejected from the impeller channel enters the volute, where it is concentrated and directed before being discharged from the centrifugal fan's outlet.

[0054] A cross-flow fan can also be called a cross-flow fan. The airflow enters the blades radially from the opening of the impeller, passes through the interior of the impeller, and is discharged into the volute from the other side of the blades, forming the working airflow. The airflow in an axial flow fan flows axially inside the impeller. The above three types of fans each have advantages and disadvantages and can be set according to actual conditions. However, no matter which type of fan 112 is used, the air heated by the indoor heat exchanger 111 can be sent to the indoor environment through the air outlet 122 to regulate the temperature of the indoor environment.

[0055] In a specific embodiment, the air outlet 122 may also be provided with a guide plate 126 and a swing blade 127. The swing blade 127 may be configured to adjust the direction of air flow from the air outlet 122. In a specific embodiment, the swing blade 127 may be configured to adjust its specific position according to the air supply mode. For example, the air supply mode may include multiple different air supply instructions, and the swing blade 127 may adjust its specific position according to different air supply instructions. The guide plate 126 may be configured to open and close the air outlet 122. When the guide plate 126 opens the air outlet 122, the air guided by the swing blade 127 can be delivered to the indoor environment. If the guide plate 126 closes the air outlet 122, no air will be blown out of the air outlet 122. Generally, when the air conditioner indoor unit 100 is turned off, the guide plate 126 may be used to close the air outlet 122 to prevent external dust from entering the interior of the housing 110 through the air outlet 122, effectively ensuring the cleanliness of the interior of the housing 110.

[0056] In summary, the air conditioner indoor unit 100 of this embodiment includes: a shell 110, in which an indoor heat exchanger 111 is arranged; a water receiving pan 130, which is arranged below the indoor heat exchanger 111 and is configured to receive condensed water at the indoor heat exchanger 111, and the water receiving pan 130 is provided with a connecting pipe 131; and a drain pipe 140, which is clamped with the connecting pipe 131 so that the condensed water in the water receiving pan 130 can flow into the drain pipe 140 through the connecting pipe 131, and by adjusting the clamping position of the drain pipe 140 and the connecting pipe 131, the total length between the water inlet 136 of the connecting pipe 131 and the water outlet 147 of the drain pipe 140 is changed, which can reduce the redundant length of the drain pipe 140, avoid bending of the drain pipe 140 and shorten its service life, and improve the user experience.

[0057] Furthermore, the air conditioner indoor unit 100 and the panel 120 of this embodiment are arranged on the front side of the shell 110, and the upper part of the panel 120 is provided with an air inlet 121, and the lower part is provided with an air outlet 122; the air conditioner indoor unit 100 is arranged in a cabinet with a forward opening, and the panel 120 faces forward, so that the air conditioner indoor unit 100 can be embedded in the cabinet while increasing the air intake volume, avoiding the indoor heat exchanger 111 from freezing due to insufficient air volume, and improving the working reliability of the indoor heat exchanger 111; the cabinet is provided with a rear wall, and the water pipe 142 is fixed to the rear wall to ensure the installation stability of the drain pipe 140, and avoid the drain pipe 140 from moving easily and causing water leakage.
