Description

Technical Field

[0001] This invention relates to the field of home appliances, and in particular to an indoor unit of a vertical air conditioner. Background Technology

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

[0003] Air conditioners can be categorized into floor-standing, wall-mounted, and ceiling-mounted types based on the installation method of their indoor units. Floor-standing air conditioners are primarily used in large public places such as living rooms, schools, and hospitals, as they can quickly provide a significant amount of cooling to the environment. Therefore, floor-standing air conditioners are widely used.

[0004] During operation, condensation occurs on the outer walls of the inlet and outlet pipes of current floor-standing air conditioner indoor units when the heat exchanger condenses. If this condensation is not treated promptly, it can lead to corrosion of the unit and, in severe cases, even short circuits, posing a safety hazard and threatening user safety. To address this issue, existing technologies typically include a drip tray to collect the condensation. This tray is usually fitted over the inlet and outlet pipes and secured with cable ties. However, inconsistent tightness of the cable ties by different operators results in poor reliability, often allowing condensation to flow down the gap between the tray and the pipes, causing water overflow from the indoor unit and impacting the user experience. Summary of the Invention

[0013] Optionally, the bottom of the water receiving tank is provided with a first drain hole, and the first drain hole has a drain pipe extending downward, configured to drain the condensate in the water receiving tank into the second water receiving device.

[0014] Optionally, a second drain hole is provided at the bottom of the second water receiving device, configured to discharge the condensate in the second water receiving device to the outside of the indoor unit of the vertical air conditioner.

[0015] Optionally, both the first and second flow guides are made of copper.

[0016] Optionally, the heat exchanger has a U-shaped cross-section with the opening facing forward.

[0017] The present invention relates to a vertical air conditioner indoor unit, comprising: a housing having an internal cavity; a heat exchanger disposed in the cavity and configured to exchange heat with air entering the cavity; an inlet pipe and an outlet pipe, both connected to the heat exchanger, wherein refrigerant flows into the heat exchanger through the inlet pipe and flows out of the heat exchanger through the outlet pipe; and a first water receiving device, sleeved outside the inlet pipe and the outlet pipe, configured to receive condensate flowing down the inlet pipe and the outlet pipe, wherein a first guide member is provided on the inlet pipe to guide the condensate flowing down the inlet pipe to the first water receiving device; and a second guide member is provided on the outlet pipe to guide the condensate flowing down the outlet pipe to the first water receiving device.

[0019] The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments of the invention in conjunction with the accompanying drawings. Attached Figure Description

[0020] The following sections will describe some specific embodiments of the invention in detail by way of example and not limitation, with reference to the accompanying drawings. The same reference numerals in the drawings denote the same or similar parts or portions. Those skilled in the art should understand that these drawings are not necessarily drawn to scale.

[0026] Figure 1 This is a structural diagram of the water collection bowl 200 of a floor-standing air conditioner indoor unit in existing technology. During operation, condensation occurs on the outer wall of the inlet and outlet liquid pipes 500 of the indoor unit's heat exchanger. If this condensation is not treated promptly, it can lead to corrosion of the unit body, and in severe cases, even short circuits, posing a safety hazard and threatening user safety. To solve this problem, such as... Figure 1 As shown, in the prior art, a separate water collection bowl 200 is generally provided for collecting condensate.

[0027] The water collection bowl 200 is usually wrapped around the inlet / outlet liquid pipe 500 and secured to it with a wire tie. However, different workers may tighten the wire tie in different ways, resulting in poor reliability of the ties. As a result, condensate often continues to flow down along the gap between the water collection bowl 200 and the inlet / outlet liquid pipe 500, causing water overflow in the indoor unit of the vertical air conditioner and affecting the user experience.

[0028] To address the problem in existing technologies where condensate easily flows downwards along the gap between the water collection bowl 200 and the inlet / outlet pipes 500, this embodiment provides a vertical air conditioner indoor unit 100. By installing a first guide 161 and a second guide 162 on the inlet pipe 130 and the outlet pipe 140 respectively, all condensate can flow into the first water collection device 150, solving the overflow problem caused by condensate flowing downwards through the gaps, improving the operational reliability of the first water collection device 150, and effectively enhancing the user experience.

[0029] Figure 2 This is a schematic diagram of the overall structure of an indoor unit 100 of a vertical air conditioner according to an embodiment of the present invention. Figure 3 This is a partial structural schematic diagram of an indoor unit 100 of a vertical air conditioner according to an embodiment of the present invention. Figure 4 yes Figure 3 An enlarged schematic diagram of region A in the middle. Figure 5 This is a schematic diagram of the structure of the first water receiving device 150 in the indoor unit 100 of a vertical air conditioner according to an embodiment of the present invention. Figures 2 to 4As shown, the indoor unit 100 of the vertical air conditioner in this embodiment generally includes: a housing 110, a heat exchanger 120, an inlet pipe 130 and an outlet pipe 140, and a first water receiving device 150.

[0030] The shell 110 has an internal cavity 111. A heat exchanger 120 can be disposed within the cavity 111 and configured to exchange heat with air entering the cavity 111. Both the inlet pipe 130 and the outlet pipe 140 can be connected to the heat exchanger 120. Refrigerant flows into the heat exchanger 120 through the inlet pipe 130 and exits through the outlet pipe 140. A first water receiving device 150 can be fitted over the inlet pipe 130 and the outlet pipe 140 and configured to collect condensate flowing down along the inlet pipe 130 and the outlet pipe 140.

[0031] It should be emphasized that a first guide member 161 can be provided on the inlet pipe 130, configured to guide the condensate flowing down the inlet pipe 130 to the first water receiving device 150. A second guide member 162 can be provided on the outlet pipe 140, configured to guide the condensate flowing down the outlet pipe 140 to the first water receiving device 150. The provision of the first guide member 161 and the second guide member 162 ensures that the condensate no longer continues to flow downwards along the gap between the first water receiving device 150 and the inlet pipe 130 and outlet pipe 140, but instead flows entirely into the first water receiving device 150 under the guidance of the first guide member 161 and the second guide member 162.

[0032] In one specific embodiment, such as Figure 4 and Figure 5 As shown, the first water receiving device 150 may include a water receiving tank 151. The condensate flowing down along the liquid inlet pipe 130 and the liquid outlet pipe 140 will flow into the water receiving tank 151. The peripheral wall of the water receiving tank 151 has a certain height, which can prevent the condensate from flowing from the periphery of the water receiving tank 151 to other components, ensuring that other components will not be corroded, and can also further avoid problems such as short circuits, ensuring the user's safety.

[0033] The bottom of the water receiving tank 151 may have an inlet hole and an outlet hole. Furthermore, the inlet hole may have an upwardly extending inlet sleeve 152 for the inlet pipe 130 to pass through; the outlet hole may have an upwardly extending outlet sleeve 153 for the outlet pipe 140 to pass through. Due to perspective, the inlet hole and outlet hole are not shown in the figure. In reality, the bottom of the inlet sleeve 152 is the inlet hole, and the bottom of the outlet sleeve 153 is the outlet hole.

[0034] In a preferred embodiment, the inner diameter of the inlet sleeve 152 can be matched with the outer diameter of the inlet pipe 130. For example, the inner diameter of the inlet sleeve 152 can be the same as the outer diameter of the inlet pipe 130, or the inner diameter of the inlet sleeve 152 can be slightly larger than the outer diameter of the inlet pipe 130. This ensures that the inlet pipe 130 can pass through the inlet sleeve 152 while minimizing the gap between the inlet pipe 130 and the inlet sleeve 152.

[0035] Similarly, the inner diameter of the liquid outlet sleeve 153 can be matched with the outer diameter of the liquid outlet pipe 140. For example, the inner diameter of the liquid outlet sleeve 153 can be the same as the outer diameter of the liquid outlet pipe 140, or the inner diameter of the liquid outlet sleeve 153 can be slightly larger than the outer diameter of the liquid outlet pipe 140. This ensures that the liquid outlet pipe 140 can pass through the liquid outlet sleeve 153 while minimizing the gap between the liquid outlet pipe 140 and the liquid outlet sleeve 153.

[0036] Since the first water receiving device 150 is sleeved on the inlet pipe 130 and the outlet pipe 140, even if the inner diameter of the inlet sleeve 152 can be matched with the outer diameter of the inlet pipe 130 and the inner diameter of the outlet sleeve 153 can be matched with the outer diameter of the outlet pipe 140 to minimize the gap, it cannot completely solve the problem of condensate flowing down the gap and causing water overflow in the indoor unit 100 of the vertical air conditioner.

[0037] This embodiment, by respectively setting a first guide member 161 and a second guide member 162 on the inlet pipe 130 and the outlet pipe 140, ensures that all condensate flows into the first water receiving device 150, solving the overflow problem caused by condensate flowing down through gaps, improving the operational reliability of the first water receiving device 150, and effectively enhancing the user experience. In a preferred embodiment, the first guide member 161 can be welded to the inlet pipe 130, and the second guide member 162 can be welded to the outlet pipe 140. The welding method ensures a very stable connection between the first guide member 161 and the inlet pipe 130, and a very stable connection between the second guide member 162 and the outlet pipe 140. The first and second guide members 161 and 162 will not move, which not only improves the reliability of the guiding operation of the first and second guide members 161 and 162, but also lays the foundation for their subsequent use as positioning components of the first water receiving device 150.

[0038] like Figure 4As shown, the first guide member 161 and the second guide member 162 can be umbrella-shaped as a whole. Furthermore, the top diameter of the first guide member 161 can be matched with the outer diameter of the inlet pipe 130, and its bottom diameter can be matched with the outer diameter of the inlet sleeve 152. The top diameter of the second guide member 162 can be matched with the outer diameter of the outlet pipe 140, and its bottom diameter can be matched with the outer diameter of the outlet sleeve 153. This matching setting can refer to identical dimensions. This ensures that the condensate is completely guided into the first water receiving device 150 by the first guide member 161 and the second guide member 162, while also preventing interference caused by excessively large sizes of the first guide member 161 and the second guide member 162, thus avoiding excessive space occupation and resulting in a reasonable structural design.

[0039] In one specific embodiment, the indoor unit 100 of the vertical air conditioner may further include a pipe clamping plate 170, disposed below the first water receiving device 150, configured to fix the inlet pipe 130 and the outlet pipe 140 to the housing 110. Furthermore, the pipe clamping plate 170 can also press the top surfaces of the inlet sleeve 152 and the outlet sleeve 153 against the bottom surfaces of the first guide member 161 and the second guide member 162, respectively, thereby enabling the first guide member 161 and the second guide member 162 to position the first water receiving device 150.

[0040] In other words, the first guide component 161 and the second guide component 162 welded to the inlet pipe 130 and the outlet pipe 140, in addition to guiding the condensate, also serve as positioning components during the assembly of the first water receiving device 150. When the top surfaces of the inlet sleeve 152 and the outlet sleeve 153 of the first water receiving device 150 are pressed against the bottom surfaces of the first guide component 161 and the second guide component 162 above, the first water receiving device 150 can be considered to be installed in place. This effectively ensures the uniformity of the installation position of the first water receiving device 150 and improves the standardization of assembly.

[0041] Furthermore, by using the pipe clamping plate 170 and the first and second guide members 161 and 162, the first water receiving device 150 can be fixed between the pipe clamping plate 170 and the first and second guide members 161 and 162. This replaces the traditional method of binding the first water receiving device 150 to the inlet pipe 130 and outlet pipe 140 with wire ties, effectively solving the problem of poor reliability of wire tie fixing. It also prevents condensate from continuing to flow downwards along the gaps between the first water receiving device 150 and the inlet and outlet pipes 130 and 140, thus avoiding water overflow in the indoor unit 100 of the vertical air conditioner. Since the pipe clamping plate 170 is located below the first water receiving device 150, while the first and second guide members 161 and 162 position the first water receiving device 150, they also effectively position the pipe clamping plate 170.

[0042] In one specific embodiment, the pipe clamping plate 170 can hold the inlet pipe 130 and the outlet pipe 140 in place and fix them to the housing 110, thereby fixing the inlet pipe 130 and the outlet pipe 140 to the housing 110. In a preferred embodiment, the pipe clamping plate 170 can be fixed to the housing 110 by screwing. Specifically, screw holes 155 can be provided at both ends of the pipe clamping plate 170 for screws to pass through and screw into the housing 110. The assembly method of screwing the pipe clamping plate 170 to the housing 110 is simple and easy to implement, and facilitates disassembly for replacement, maintenance, and other operations.

[0043] This embodiment provides a vertical air conditioner indoor unit 100. Vertical air conditioners, as a type of split-type air conditioner, are commonly used in homes, offices, and other places. Compared to wall-mounted air conditioners, vertical air conditioners have advantages such as higher power and stronger airflow, but their starting price is also relatively higher. The vertical air conditioner indoor unit 100 is generally suitable for larger indoor environments; for example, it is best to choose a vertical air conditioner indoor unit 100 for larger living rooms to ensure good cooling, heating, and airflow effects.

[0044] In this embodiment, the first water-collecting device 150 is mainly applicable to the indoor unit 100 of a vertical air conditioner. This is because the vertical arrangement of the inlet pipe 130 and outlet pipe 140 causes condensate to flow downwards along the inlet pipe 130 and outlet pipe 140, allowing the first water-collecting device 150 to be fitted outside the inlet pipe 130 and outlet pipe 140, thus achieving the effect of collecting condensate. However, if other types of indoor air conditioners, such as wall-mounted or ceiling-mounted indoor air conditioners, are also suitable for this type of indoor air conditioner, and if the arrangement of the inlet pipe 130 and outlet pipe 140 allows the first water-collecting device 150 to also collect condensate, then the first water-collecting device 150 can also be applied to these types of indoor air conditioners.

[0045] like Figure 3 As shown, the housing 110 of the indoor unit 100 of the vertical air conditioner may include a rear housing 112. The rear housing 112 may have an air inlet 113, through which external air enters the cavity 111 inside the housing 110. In a specific embodiment, a heat exchanger 120 is disposed within the cavity 111 at the air inlet 113. This ensures that external air entering the cavity 111 through the air inlet 113 can directly exchange heat through the heat exchanger 120.

[0046] The housing 110 may further include a second water receiving device 114, disposed below the heat exchanger 120, configured to receive condensate produced by the heat exchanger 120. Because the surface temperature of the heat exchanger 120 is low during the cooling process of the indoor unit 100 of the vertical air conditioner, moisture in the air will condense on the surface of the heat exchanger 120. Similarly, this is also the reason why condensate will appear on the surfaces of the liquid inlet pipe 130 and the liquid outlet pipe 140.

[0047] The first water receiving device 150 collects the condensate flowing down along the liquid inlet pipe 130 and the liquid outlet pipe 140, while the second water receiving device 114 collects the condensate generated by the heat exchanger 120. This ensures that all the condensate generated inside the indoor unit 100 of the vertical air conditioner is effectively treated, guaranteeing the normal operation of all components inside the indoor unit 100, extending the service life of each component, and improving user safety.

[0048] The second water receiving device 114 and the rear shell 112 can be separate components, not integrally formed. The specific installation positions of the second water receiving device 114 and the rear shell 112 can be determined by positioning posts, and then fixed by screws. In other words, the second water receiving device 114 and the rear shell 112 can be fixed by screw connection, and the whole can be regarded as part of the shell 110.

[0049] like Figure 3 and Figure 4 As shown, a right column 115 can be provided on the right side of the second water receiving device 114. The right column 115 can be a part of the second water receiving device 114. As mentioned earlier, screw holes 155 are provided at both ends of the pipe pressure plate 170 for screws to pass through and be screwed into the housing 110. Specifically, the left end of the pipe pressure plate 170 can be screwed into the right column 115, and the right end of the pipe pressure plate 170 can be screwed into the right side of the rear housing 112. That is to say, the left end of the pipe pressure plate 170 is actually fixed to the second water receiving device 114, and the right end of the pipe pressure plate 170 is actually fixed to the rear housing 112. Since the second water receiving device 114 and the rear housing 112 can both be regarded as part of the housing 110, it can be considered that the pipe pressure plate 170 is fixed to the housing 110.

[0050] like Figure 5 As shown, the bottom of the water receiving tank 151 may also be provided with a first drain hole 156, and the first drain hole 156 may have a downwardly extending drain pipe 157, configured to drain the condensate in the water receiving tank 151 into the second water receiving device 114. That is to say, the second water receiving device 114 can be located below the first drain hole 156 and the drain pipe 157, so that the condensate flowing out of the drain pipe 157 can flow smoothly into the second water receiving device 114.

[0051] like Figure 3 and Figure 4 As shown, a second drain hole 116 can be provided at the bottom of the second water receiving device 114, configured to discharge the condensate in the second water receiving device 114 to the outside of the indoor unit 100 of the vertical air conditioner. That is, after the condensate flowing down along the inlet pipe 130 and outlet pipe 140 flows into the first water receiving device 150, this portion of condensate can flow into the second water receiving device 114 through the drain pipe 157. Since the second water receiving device 114 already receives condensate produced by the heat exchanger 120, it can discharge all the condensate flowing in from any path to the outside of the indoor unit 100 of the vertical air conditioner. Timely and effective drainage of the condensate inside the indoor unit 100 of the vertical air conditioner ensures its normal operation.

[0052] In one specific embodiment, such as Figure 2 As shown, the housing 110 of the indoor unit 100 of the vertical air conditioner may further include a front housing 117, and the front housing 117 may have an air outlet 119. As mentioned above, the housing 110 includes a rear housing 112, and the rear housing 112 has an air inlet 113. In fact, the rear housing 112 may include an upper air inlet grille and a lower decorative panel. Figure 3 The rear shell 112 shown is actually part of the upper air intake grille, and the lower decorative panel (not shown) can be set at the lower part of the upper air intake grille. Specifically, the air inlet 113 of the upper air intake grille can be in the form of a grille, so as to perform preliminary filtration of the outside air entering the cavity 111 through the air inlet 113, thereby improving the cleanliness of the air discharged from the indoor unit 100 of the vertical air conditioner.

[0053] As mentioned earlier, the heat exchanger 120 is located in the cavity 111 defined inside the housing 110. In practice, the heat exchanger 120 can be located in the cavity area corresponding to the upper air inlet grille, thereby exchanging heat with the external air entering the cavity through the air inlet of the upper air inlet grille. The cavity area corresponding to the lower decorative panel can house components such as an electronic control board and a temperature sensor. The electronic control board controls the overall operation of the indoor unit of the vertical air conditioner, while the temperature sensor accurately detects the actual temperature of the environment surrounding the indoor unit, thereby adjusting the specific operating mode of the indoor unit based on the actual temperature.

[0054] In addition, the housing 110 may also include panels such as a top plate and a bottom plate. The top and bottom plates improve the overall integrity of the vertical air conditioner indoor unit 100 and make it more stable when installed in an indoor environment. In this embodiment, the front housing 117 and the rear housing 112 of the vertical air conditioner indoor unit 100 can be directly connected without additional side plates. In some other embodiments, the housing 110 may also include side plates, which may include a left side plate and a right side plate, respectively connected to the front housing 117 and the rear housing 112.

[0055] In one specific embodiment, the air inlet 113 and air outlet 119 of the indoor unit 100 of the vertical air conditioner can be considered to form an air duct. As mentioned earlier, the heat exchanger 120 is disposed within the cavity 111 defined inside the housing 110; it can also be considered that the heat exchanger 120 is disposed within the air duct. When the indoor unit 100 of the vertical air conditioner is operating in cooling mode, the air that has undergone heat exchange through the heat exchanger 120 is cold air, which, after being delivered to the indoor environment through the air outlet 119, can lower the indoor temperature, making the user feel cool. When the indoor unit 100 of the vertical air conditioner is operating in heating mode, the air that has undergone heat exchange through the heat exchanger 120 is hot air, which, after being delivered to the indoor environment through the air outlet 119, can raise the indoor temperature, making the user feel warm.

[0056] As mentioned earlier, the heat exchanger 120 is disposed within the cavity 111 at the air inlet 113, ensuring that external air entering the cavity 111 through the air inlet 113 can directly exchange heat through the heat exchanger 120. In a preferred embodiment, the heat exchanger 120 has a U-shaped cross-section with its opening facing forward. The U-shaped cross-section of the heat exchanger 120 effectively ensures the heat exchange area of ​​the heat exchanger 120, thereby improving heat exchange efficiency. Furthermore, the forward-facing opening of the heat exchanger 120 prevents the air after heat exchange from being blocked, allowing for smooth airflow.

[0057] The length and width of the heat exchanger 120 can be matched with the air inlet 113. For example, the overall length and width of the air inlet 113 and the heat exchanger 120 can be the same, thereby further ensuring that the air entering the cavity 111 through the air inlet 113 can be completely heated by the heat exchanger 120, improving heat exchange efficiency. In addition, a fan (not shown in the figure) can also be installed in the cavity 111. After the indoor unit 100 of the vertical air conditioner is turned on to the air supply mode, the fan is turned on, and the air heated by the heat exchanger 120 can be sent to the indoor environment through the air outlet 119 by the action of the fan.

[0058] The fans in the indoor unit 100 of a vertical air conditioner can mainly include three types: centrifugal, cross-flow, and axial flow. In a centrifugal fan, the air inside is subjected to centrifugal force, creating a vacuum in the center of the impeller. The drawn-in air is turned 90° at the impeller inlet and enters the flow channel formed by the blades, gaining kinetic and pressure energy under the action of the blades. The airflow then exits from the blade channel into the volute, where it is concentrated and guided before being discharged from the centrifugal fan outlet.

[0059] Crossflow fans, also known as cross-flow fans, allow airflow to enter radially from the open end of the impeller, pass through the interior of the impeller, and exit into the volute from the other side of the impeller, forming the working airflow. In axial flow fans, the airflow is axial within the impeller. Each of these three types of fans has its advantages and disadvantages, and the appropriate configuration can be chosen based on specific circumstances. Regardless of the type, all fans can deliver the air heated by the heat exchanger 120 to the indoor environment through the outlet 119, regulating the indoor temperature and airflow. The airflow speed of the indoor unit 100 of the vertical air conditioner can be adjusted by regulating the fan speed.

[0060] Furthermore, the air outlet 119 may be equipped with horizontal and vertical swivel blades (not shown in the figure). The vertical swivel blades are configured to adjust the left-right airflow direction of the air outlet 119, and the horizontal swivel blades are configured to adjust the up-down airflow direction of the air outlet 119. In a specific embodiment, the horizontal and vertical swivel blades are configured to adjust their specific posture according to the air supply mode. For example, the air supply mode may include a variety of different air supply commands, and the horizontal and vertical swivel blades can adjust their specific posture according to different air supply commands.

[0061] More specifically, the vertical oscillating blades can be positioned to the left, center, or right. The horizontal oscillating blades can be positioned upwards, center, or downwards. In a preferred embodiment, the horizontal and vertical oscillating blades can also be adjusted to change the specific angle of airflow to achieve different air volumes.

[0062] Regarding the specific orientation of the horizontal louvers, with the louvers pointing upwards, the indoor unit 100 of the vertical air conditioner can direct airflow upwards, which is particularly suitable when the indoor unit 100 is operating in cooling mode. Since the indoor unit 100 delivers cold air in cooling mode, according to the characteristics of cold air, it will gradually sink after being blown upwards, thus lowering the temperature of the entire indoor environment. Preventing direct cold airflow can also effectively avoid headaches, colds, and other ailments for users.

[0063] With the horizontal louvers pointing downwards, the indoor unit 100 of the vertical air conditioner directs airflow downwards, which is particularly suitable when the indoor unit 100 is operating in heating mode. Since the indoor unit 100 delivers hot air in heating mode, according to the characteristics of hot air, it gradually rises after being blown downwards, thus raising the temperature of the entire indoor environment. This downward blowing of hot air also more effectively reaches the user, making them feel warm and comfortable.

[0064] In addition, such as Figure 2 As shown, an air outlet guide plate 118 can also be installed at the air outlet 119, configured to controllably open and close the air outlet 119. When the air outlet 119 is open with the air outlet guide plate 118, the air guided by the horizontal and vertical sway blades can be delivered to the indoor environment. If the air outlet guide plate 118 closes the air outlet 119, no air will blow out from the air outlet 119. Generally, when the indoor unit 100 of the vertical air conditioner is closed, the air outlet guide plate 118 can be used to close the air outlet 119 to prevent external dust from entering the interior of the housing 110 through the air outlet 119, effectively ensuring the cleanliness of the interior of the housing 110.

[0065] In summary, the indoor unit 100 of the vertical air conditioner in this embodiment includes: a housing 110, which internally defines a cavity 111; a heat exchanger 120 disposed in the cavity 111 and configured to exchange heat with air entering the cavity 111; an inlet pipe 130 and an outlet pipe 140, both connected to the heat exchanger 120, wherein refrigerant flows into the heat exchanger 120 through the inlet pipe 130 and flows out of the heat exchanger 120 through the outlet pipe 140; and a first water receiving device 150 sleeved outside the inlet pipe 130 and the outlet pipe 140, configured to receive condensate flowing down along the inlet pipe 130 and the outlet pipe 140, wherein the inlet pipe 130... A first guide element 161 is provided on the inlet pipe 130 to guide the condensate flowing down the inlet pipe 130 to the first water receiving device 150; a second guide element 162 is provided on the outlet pipe 140 to guide the condensate flowing down the outlet pipe 140 to the first water receiving device 150. By providing the first guide element 161 and the second guide element 162 on the inlet pipe 130 and the outlet pipe 140 respectively, all the condensate can flow into the first water receiving device 150, solving the problem of overflow caused by condensate flowing down through gaps, improving the working reliability of the first water receiving device 150, and effectively enhancing the user experience.

[0066] Furthermore, in this embodiment, the first water receiving device 150 of the vertical air conditioner indoor unit 100 includes: a water receiving tank 151, with an inlet hole and an outlet hole at the bottom of the water receiving tank 151; the inlet hole has an upwardly extending inlet sleeve 152 for the inlet pipe 130 to pass through; the outlet hole has an upwardly extending outlet sleeve 153 for the outlet pipe 140 to pass through; the vertical air conditioner indoor unit also includes: a pipe pressure plate 170, which is disposed below the first water receiving device 150 and configured to fix the inlet pipe 130 and the outlet pipe 140 to the housing 110, and press the top surfaces of the inlet sleeve 152 and the outlet sleeve 153 against the bottom surfaces of the first guide member 161 and the second guide member 162 respectively, so that the first guide member 161 and the second guide member 162 can position the first water receiving device 150, ensuring that the installation position of the first water receiving device 150 is uniform and improving the standardization of assembly.
