Vertical air conditioner indoor units are mainly used in public places such as living rooms with large areas, schools, hospitals, etc. They can provide more cooling capacity to the environment quickly, so vertical air conditioners are widely used.

[0004] During the operation of the indoor unit of the current vertical air conditioner, condensed water will appear on the outer wall of the inlet and outlet liquid pipes of the indoor unit's heat exchanger when condensing. If the condensed water is not handled in time, it will cause corrosion to the fuselage. In severe cases, it may even cause some circuits to short-circuit, becoming a safety hazard and threatening the user's safety. In order to solve this problem, the prior art generally provides a separate water receiving bowl for collecting condensed water.

[0026] Figure 1 The structure diagram of the water receiving bowl 200 and the tube pressing plate 300 of the indoor unit of the vertical air conditioner in the prior art. During the operation of the indoor unit of the vertical air conditioner, condensed water will appear on the outer wall of the inlet and outlet liquid pipes 500 of the heat exchanger of the indoor unit when condensing. If the condensed water is not handled in time, it will cause corrosion of the machine body. In severe cases, it may even cause some circuits to short-circuit, becoming a safety hazard and threatening the user's safety. In order to solve this problem, Figure 1 As shown, in the prior art, a water receiving bowl 200 is generally separately provided for collecting condensed water.

[0027] However, in the prior art, in order to ensure the installation stability of the inlet and outlet liquid pipes 500, a pipe clamping plate 300 is often provided below the water receiving bowl 200 for collecting condensed water, so as to fix the inlet and outlet liquid pipes 500 to other structures, such as the air duct 400 of the indoor unit of a vertical air conditioner. The overall structure of the water receiving bowl 200 and the pipe clamping plate 300 is relatively complicated. In addition, the pipe clamping plate 300 needs to be installed separately, and manual assembly is relatively troublesome; the pipe clamping plate 300 also needs to be molded separately, and the production cost is relatively high.

[0028] In order to solve the problem that the overall structure of the water receiving bowl 200 and the tube pressing plate 300 in the prior art is relatively complex, and the tube pressing plate 300 needs to be installed and molded separately, this embodiment provides a vertical air conditioner indoor unit 100, which can receive condensed water from the liquid inlet pipe 130 and the liquid outlet pipe 140 of the heat exchanger 120 of the vertical air conditioner indoor unit 100 by setting a first water receiving device 150, and can also fix the liquid inlet pipe 130 and the liquid outlet pipe 140. A single structure can achieve multiple functions at the same time, effectively improving modular integration.

[0029] Figure 2 1 is a schematic diagram of the overall structure of a vertical air conditioner indoor unit 100 according to an embodiment of the present invention. Figure 3 is a partial structural diagram of a vertical air conditioner indoor unit 100 according to an embodiment of the present invention. Figure 4 yes Figure 3 The enlarged schematic diagram of area A in the middle, Figure 5 FIG. 1 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 4 As shown, the vertical air conditioner indoor unit 100 of this embodiment may generally include: a housing 110 , a heat exchanger 120 , a liquid inlet pipe 130 , a liquid outlet pipe 140 , and a first water receiving device 150 .

[0030] The shell 110 defines a cavity 111 inside. The heat exchanger 120 can be disposed in the cavity 111, and is configured to perform heat exchange on the air entering the cavity 111. The liquid inlet pipe 130 and the liquid outlet pipe 140 can both be connected to the heat exchanger 120, and the refrigerant flows into the heat exchanger 120 through the liquid inlet pipe 130 and flows out of the heat exchanger 120 through the liquid outlet pipe 140. The first water receiving device 150 can be sleeved on the outside of the liquid inlet pipe 130 and the liquid outlet pipe 140, and is configured to receive the condensed water flowing down along the liquid inlet pipe 130 and the liquid outlet pipe 140.

[0031] It should be emphasized that the first water receiving device 150 is fixedly connected to the housing 110, so that the liquid inlet pipe 130 and the liquid outlet pipe 140 are fixed to the housing 110. This is because the first water receiving device 150 is sleeved on the outside of the liquid inlet pipe 130 and the liquid outlet pipe 140. When the first water receiving device 150 is fixedly connected to the housing 110, the liquid inlet pipe 130 and the liquid outlet pipe 140 can be indirectly fixed to the housing 110, thereby improving the installation stability of the liquid inlet pipe 130 and the liquid outlet pipe 140. The vertical air conditioner indoor unit 100 of this embodiment can not only receive the condensed water of the liquid inlet and outlet pipes 140, but also fix the liquid inlet and outlet pipes 140 by providing the first water receiving device 150. A single structure can simultaneously achieve multiple functions, effectively improving modular integration.

[0032] In a specific embodiment, Figure 4 and Figure 5 As shown, the first water receiving device 150 may include: a water receiving trough 151, and the condensed water flowing down the liquid inlet pipe 130 and the liquid outlet pipe 140 will flow into the water receiving trough 151. The surrounding wall of the water receiving trough 151 has a certain height, which can prevent the condensed water from flowing from the surroundings of the water receiving trough 151 to other components, ensuring that other components will not be corroded, and can further avoid problems such as line short circuits, thereby ensuring the safety of users.

[0033] The bottom of the water receiving tank 151 may be provided with a liquid inlet hole and a liquid outlet hole. In addition, the liquid inlet hole may have a liquid inlet sleeve 152 extending upwards for the liquid inlet pipe 130 to pass through; the liquid outlet hole may have a liquid outlet sleeve 153 extending upwards for the liquid outlet pipe 140 to pass through. Due to the viewing angle, the liquid inlet hole and the liquid outlet hole are not shown in the figure. In fact, the bottom of the liquid inlet sleeve 152 is the liquid inlet hole, and the bottom of the liquid outlet sleeve 153 is the liquid outlet hole.

[0034] In a preferred embodiment, the inner diameter of the liquid inlet sleeve 152 can be matched with the outer diameter of the liquid inlet pipe 130. For example, the inner diameter of the liquid inlet sleeve 152 can be the same as the outer diameter of the liquid inlet pipe 130, or the inner diameter of the liquid inlet sleeve 152 can be slightly larger than the outer diameter of the liquid inlet pipe 130. In this way, while ensuring that the liquid inlet pipe 130 can pass through the liquid inlet sleeve 152, it can also ensure that the gap between the liquid inlet pipe 130 and the liquid inlet sleeve 152 is very small or negligible, thereby preventing condensed water from flowing downward along the gap and causing overflow of the vertical air conditioner indoor unit 100.

[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. In this way, while ensuring that the liquid outlet pipe 140 can pass through the liquid outlet sleeve 153, it can also ensure that the gap between the liquid outlet pipe 140 and the liquid outlet sleeve 153 is very small or negligible, thereby preventing condensed water from flowing downward along the gap and causing overflow of the vertical air conditioner indoor unit 100.

[0036] In a specific embodiment, the first water receiving device 150 may further include: a connecting portion 154, located at the front of the water receiving groove 151, and configured to be fixedly connected to the housing 110. That is to say, the first water receiving device 150 is fixedly connected to the housing 110, which is actually achieved through the connecting portion 154. More specifically, screw holes 155 may be provided at the left and right ends of the connecting portion 154 for screwing through the housing 110. The assembly method of the connecting portion 154 being screwed to the housing 110 is simple and easy, and is convenient for disassembly for replacement, maintenance, and other operations.

[0037] In a preferred embodiment, the first water receiving device 150 can be integrally formed. That is, the front wall of the water receiving groove 151 can be the connecting portion 154. The integral formation of the water receiving groove 151 and the connecting portion 154 can effectively avoid the problem of gaps between the two as separate parts, ensuring that condensed water will not flow out to other parts through the gaps, further improving the working reliability of the first water receiving device 150. The vertical air conditioner indoor unit 100 of this embodiment, through the integrated structure setting of the first water receiving device 150, avoids the separate installation of the water receiving bowl and the pipe pressure plate, reduces the difficulty of assembly, and avoids the separate mold opening of the pipe pressure plate, effectively saving production costs.

[0038] The present embodiment provides a vertical air conditioner indoor unit 100. As a type of split air conditioner, the vertical air conditioner can be generally used in homes, offices and other places. Compared with wall-mounted air conditioners, the vertical air conditioner has the advantages of high power and strong wind force, and the starting price is relatively higher. The vertical air conditioner indoor unit 100 is usually suitable for indoor environments with larger areas. For example, if the living room area is relatively large, it is best to use the vertical air conditioner indoor unit 100 to ensure good cooling, heating and air supply effects.

[0039] The first water receiving device 150 in this embodiment is mainly applicable to the vertical air conditioner indoor unit 100. This is because the vertical setting state of the liquid inlet pipe 130 and the liquid outlet pipe 140 causes the condensed water to flow downward along the liquid inlet pipe 130 and the liquid outlet pipe 140, so that the first water receiving device 150 is sleeved on the outside of the liquid inlet pipe 130 and the liquid outlet pipe 140, and can achieve the effect of receiving the condensed water. However, if other types of air conditioner indoor units, such as wall-mounted air conditioner indoor units and ceiling-mounted air conditioner indoor units, are set in a manner and the relative position between the liquid inlet pipe 130 and the liquid outlet pipe 140 and the shell 110 so that the first water receiving device 150 can also receive the condensed water and be fixed to the shell 110, then the first water receiving device 150 can also be applied to these types of air conditioner indoor units.

[0040] like Figure 3 As shown, the housing 110 of the vertical air conditioner indoor unit 100 may include a rear housing 112. In addition, the rear housing 112 may be provided with an air inlet 113, and external air may enter the cavity 111 inside the housing 110 through the air inlet 113. In a specific embodiment, the heat exchanger 120 is arranged at the air inlet 113 in the cavity 111. In this way, it can be ensured that the external air entering the cavity 111 through the air inlet 113 can directly pass through the heat exchanger 120 for heat exchange.

[0041] The housing 110 may further include: a second water receiving device 114, which is disposed below the heat exchanger 120 and configured to receive condensed water generated by the heat exchanger 120. Since the surface temperature of the heat exchanger 120 is relatively low during the cooling process of the vertical air conditioner indoor unit 100, moisture in the air will form condensed water on the surface of the heat exchanger 120. Similarly, this is also the reason why condensed water appears on the surface of the liquid inlet pipe 130 and the liquid outlet pipe 140.

[0042] The first water receiving device 150 receives the condensed water flowing down the liquid inlet pipe 130 and the liquid outlet pipe 140, and the second water receiving device 114 receives the condensed water generated by the heat exchanger 120, which can ensure that all the condensed water generated inside the vertical air conditioner indoor unit 100 is effectively processed, ensure the normal operation of the internal components of the vertical air conditioner indoor unit 100, extend the service life of the components, and improve the user's safety.

[0043] The second water receiving device 114 and the rear shell 112 can be separated, that is, not integrally formed. The second water receiving device 114 and the rear shell 112 can be installed in specific positions by means of positioning columns, and then can be fixed by screws. In other words, the second water receiving device 114 and the rear shell 112 can be fixed by screwing, and then the whole can be regarded as a part of the housing 110.

[0044] like Figure 3 and Figure 4As shown, a right column 115 may be provided on the right side of the second water receiving device 114. The right column 115 may be a part of the second water receiving device 114. As mentioned above, screw holes 155 are provided at the left and right ends of the connecting portion 154 of the first water receiving device 150 for screwing through the screws to be screwed to the housing 110. Specifically, the left end of the connecting portion 154 may be screwed to the right column 115, and the right end of the connecting portion 154 may be screwed to the right side of the rear shell 112. In other words, the left end of the connecting portion 154 is actually fixed to the second water receiving device 114, and the right end of the connecting portion 154 is actually fixed to the rear shell 112. Since the second water receiving device 114 and the rear shell 112 can be regarded as a part of the housing 110 as a whole, it can be considered that the connecting portion 154 of the first water receiving device 150 is fixed to the housing 110.

[0045] like Figure 5 As shown, a first drain hole 156 may be provided at the bottom of the water receiving tank 151, and a drain pipe 157 may be provided at the first drain hole 156 to drain the condensed water in the water receiving tank 151 into the second water receiving device 114. In other words, the second water receiving device 114 may be located below the first drain hole 156 and the drain pipe 157, so that the condensed water flowing out of the drain pipe 157 can flow smoothly into the second water receiving device 114.

[0046] like Figure 3 and Figure 4 As shown, the second water receiving device 114 may be provided with a second drain hole 116 at the bottom thereof, configured to discharge the condensed water in the second water receiving device 114 to the outside of the vertical air conditioner indoor unit 100. That is, after the condensed water flowing down the liquid inlet pipe 130 and the liquid outlet pipe 140 flows into the first water receiving device 150, this part of the condensed water may flow into the second water receiving device 114 through the drain pipe 157. Since the second water receiving device 114 originally receives the condensed water generated by the heat exchanger 120, the second water receiving device 114 may discharge all the condensed water flowing into it from any route to the outside of the vertical air conditioner indoor unit 100. Timely and effective discharge of the condensed water inside the vertical air conditioner indoor unit 100 may ensure the normal operation of the vertical air conditioner indoor unit 100.

[0047] In a specific embodiment, Figure 2 As shown, the housing 110 of the vertical air conditioner indoor unit 100 may further include a front housing 117, and the front housing 117 may be provided with an air outlet 119. As mentioned above, the housing 110 includes a rear housing 112, and the rear housing 112 is provided with an air inlet 113. In fact, the rear housing 112 may include an upper air inlet grille and a lower decorative plate. Figure 3The rear shell 112 shown is actually part of the upper air inlet grille, and the lower decorative plate (not shown in the figure) can be arranged at the lower part of the upper air inlet grille. Specifically, the air inlet 113 of the upper air inlet grille can be in the form of a grille, so that the external air entering the cavity 111 through the air inlet 113 can be initially filtered, thereby improving the cleanliness of the air discharged by the indoor unit 100 of the vertical air conditioner.

[0048] As mentioned above, the heat exchanger 120 is disposed in the cavity 111 defined inside the housing 110. In fact, the heat exchanger 120 can be disposed in the cavity area corresponding to the upper air inlet grille, so as to perform heat exchange on the external air entering the cavity through the air inlet of the upper air inlet grille. The cavity area corresponding to the lower decorative plate can be provided with components such as an electric control board and a temperature sensor. The electric control board can control the overall working process of the indoor unit of the vertical air conditioner, and the temperature sensor can accurately detect the actual temperature of the environment in which the indoor unit of the vertical air conditioner is located, so as to adjust the specific process of the working mode of the indoor unit of the vertical air conditioner according to the actual temperature.

[0049] In addition, the housing 110 may also include panels such as a top plate and a bottom plate, wherein the arrangement of the top plate and the bottom plate may make the vertical air conditioner indoor unit 100 more integrated and more stable when the vertical air conditioner indoor unit 100 is arranged in an indoor environment. The front shell 117 and the rear shell 112 of the vertical air conditioner indoor unit 100 of this embodiment may be directly connected without additionally arranging a side plate. In some other embodiments, the housing 110 may also include a side plate, and the side plate may include a left side plate and a right side plate, which are respectively connected to the front shell 117 and the rear shell 112.

[0050] In a specific embodiment, it can be considered that an air duct is formed between the air inlet 113 and the air outlet 119 of the vertical air conditioner indoor unit 100. As mentioned above, the heat exchanger 120 is arranged in the cavity 111 defined inside the shell 110, and it can also be considered that the heat exchanger 120 is arranged in the air duct. When the vertical air conditioner indoor unit 100 operates in the cooling mode, the air heated by the heat exchanger 120 is cold air, which can reduce the temperature of the indoor environment after being sent to the indoor environment through the air outlet 119, so that the user feels cool. When the vertical air conditioner indoor unit 100 operates in the heating mode, the air heated by the heat exchanger 120 is hot air, which can increase the temperature of the indoor environment after being sent to the indoor environment through the air outlet 119, so that the user feels warm.

[0051] As mentioned above, the heat exchanger 120 is arranged at the air inlet 113 in the cavity 111, so that the external air entering the cavity 111 through the air inlet 113 can directly pass through the heat exchanger 120 for heat exchange. In a preferred embodiment, the cross-section of the heat exchanger 120 can be U-shaped, and the opening faces forward. The heat exchanger 120 with a U-shaped cross-section can effectively guarantee the heat exchange area of ​​the heat exchanger 120, thereby improving the heat exchange efficiency. And the opening of the heat exchanger 120 faces forward, which can avoid the air after heat exchange from being blocked and can flow smoothly.

[0052] 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, so as to further ensure that the air entering the cavity 111 through the air inlet 113 can be completely heat exchanged by the heat exchanger 120, thereby improving the heat exchange efficiency. In addition, a fan (not shown in the figure) can also be arranged in the cavity 111. After the vertical air conditioner indoor unit 100 turns on the air supply mode, the fan is turned on, and the air after the heat exchange of the heat exchanger 120 can be sent to the indoor environment through the air outlet 119 through the action of the fan.

[0053] The fan of the vertical air conditioner indoor unit 100 can mainly include three types: centrifugal, cross-flow and axial flow. Among them, the air in the centrifugal fan is subjected to the centrifugal force, and a vacuum is generated in the center of the impeller. The inhaled air turns 90 degrees at the impeller inlet and enters the flow channel formed by the blades, and obtains kinetic energy and pressure energy under the action of the blades. Then the airflow thrown out from the blade channel enters the volute, and after being concentrated and guided, it is discharged from the outlet of the centrifugal fan.

[0054] A cross-flow fan can also be called a cross-flow fan. The airflow enters the blade grid radially from the opening of the impeller, passes through the inside of the impeller, and is discharged into the volute from the other side of the blade grid to form a working airflow. The airflow in the axial flow fan flows axially in 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 is used, the air after heat exchange in the heat exchanger 120 can be sent to the indoor environment through the air outlet 119 to adjust the temperature and air flow of the indoor environment. The air supply speed of the indoor unit 100 of the vertical air conditioner can be adjusted by adjusting the speed of the fan.

[0055] In addition, the air outlet 119 may be provided with a transverse swing blade and a vertical swing blade (not shown in the figure), the vertical swing blade is configured to adjust the left and right air outlet direction of the air outlet 119, and the transverse swing blade is configured to adjust the up and down air outlet direction of the air outlet 119. In a specific embodiment, the transverse swing blade and the vertical swing blade are configured to adjust the specific posture according to the air supply mode. For example, the air supply mode may include a plurality of different air supply instructions, and the transverse swing blade and the vertical swing blade may adjust the specific posture according to different air supply instructions.

[0056] More specifically, the specific postures of the vertical swing blades may include facing left, facing center, and facing right. The specific postures of the transverse swing blades include facing upward, facing center, and facing downward. In a preferred embodiment, the transverse swing blades and the vertical swing blades can also adjust the specific angles of the air outlet to achieve different air outlet volumes.

[0057] As for the specific posture of the horizontal swing blade, the horizontal swing blade faces upward, so that the vertical air conditioner indoor unit 100 can discharge air upward, which is more suitable for the case where the vertical air conditioner indoor unit 100 operates in the cooling mode. Since the vertical air conditioner indoor unit 100 delivers cold air in the cooling mode, according to the characteristics of the cold air, it will gradually sink after being blown upward, so that the temperature of the entire indoor environment can be reduced. Cold air direct blowing prevention can also effectively prevent users from having headaches, colds, etc.

[0058] The horizontal swing blades face downward, so that the vertical air conditioner indoor unit 100 can discharge air downward, which is more suitable for the vertical air conditioner indoor unit 100 to operate in the heating mode. Since the vertical air conditioner indoor unit 100 delivers hot air in the heating mode, according to the characteristics of hot air, it will gradually rise after being blown downward, so that the temperature of the entire indoor environment can be increased. The hot air blowing downward can also be blown to the user more effectively, making the user feel warm and comfortable.
