Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular, to a drainage device and an air conditioner. Background Art

[0002] For example, an air conditioner such as a duct machine needs to have device structures for water receiving and drainage to receive and discharge the condensed water generated by heat exchange of a heat exchanger. Usually, a water receiving tray is arranged below the heat exchanger for water receiving, and a water pump is arranged in the air conditioner for drainage. In order to ensure smooth drainage, the fixedly arranged water pump needs to be adjacent to the water receiving tray. Currently, after the air conditioner has been used for a long time, or during the maintenance process of the air conditioner, the water receiving tray needs to be disassembled and cleaned. Generally, the position of the water pump in the air conditioner is relatively fixed. In this case, when the water receiving tray is disassembled, the water pump will interfere with the movement of the water receiving tray, so that the water receiving tray cannot be directly moved and disassembled. Summary of the Invention

[0003] The problem solved by the present invention is how to avoid the interference of the water pump with the disassembly and movement of the water receiving tray to facilitate the disassembly and assembly of the water receiving tray.

[0004] To solve the above problems, the present invention provides a drainage device, including a water receiving tray and a drainage pump assembly. A receiving groove is formed on the water receiving tray. The drainage pump assembly is connected to the water receiving tray, and at least part of the drainage pump assembly is located in the receiving groove.

[0005] In this technical solution, the drainage device can be movably arranged as a whole inside an air conditioner such as an air duct machine. In a certain position state of the drainage device, the whole drainage device is located below the heat exchanger of the air duct machine, so that the water receiving tray can receive the condensed water generated by the heat exchanger, thereby avoiding the influence of the condensed water on the operation of the air conditioner. Among them, a drainage pump assembly is arranged to cooperate with the water receiving tray. After the water receiving tray receives a certain amount of condensed water, the condensed water can be quickly drained through the drainage pump assembly, so as to quickly drain the condensed water completely. The drainage pump assembly is arranged on the water receiving tray, so that the drainage pump assembly can move synchronously with the water receiving tray. When the water receiving tray needs to be disassembled and cleaned, the drainage pump assembly will not interfere with the water receiving tray due to the positional relationship between the drainage pump assembly and the water receiving tray. When installing the water receiving tray, it is not necessary to deliberately adjust the position of the drainage pump assembly. After the water receiving tray is installed, then move the position of the drainage pump assembly or perform subsequent installation steps, so as to facilitate the disassembly and assembly of the water receiving tray in the air conditioner. A receiving groove is formed on the water receiving tray, and the groove structure can have a certain receiving space, so that it can have a certain water receiving and storing capacity, avoiding the spilling of condensed water after receiving and storing water. And at least part of the drainage pump assembly is located in the receiving groove. In this way, on the one hand, the part of the drainage pump assembly located in the receiving groove can be close to the condensed water, so as to achieve a better pumping and drainage effect. At the same time, when the whole drainage device is moved during disassembly and installation, etc., because the drainage pump assembly of the drainage device moves at the same time, at this time, for example, inside the air duct machine of the air conditioner, the drainage pump assembly may interfere with and collide with the internal structure of the air duct machine, which also causes problems such as inconvenient disassembly and installation. Therefore, at least part of the drainage pump assembly is located in the receiving groove. At this time, because the receiving groove has a certain receiving space, after receiving the drainage pump assembly, the overall height of the drainage device can be lower, and at this time, the interference that is not conducive to disassembly and installation can be avoided as much as possible.

[0006] Further, the drainage pump assembly includes a mounting bracket and a drainage pump arranged on the mounting bracket, and the mounting bracket is fixedly connected to the water receiving tray.

[0007] In this technical solution, setting the mounting bracket can also facilitate the fixed installation and disassembly of the drainage pump, and make the drainage pump more firmly fixed.

[0008] Further, the mounting bracket includes a top plate and first and second support plates arranged oppositely. The first and second support plates are connected to the water receiving tray. The top plate is located between the first and second support plates and is respectively connected to the first and second support plates. An accommodation cavity is formed by the top plate, the first support plate, the second support plate and the water receiving tray, and the drainage pump is located in the accommodation cavity.

[0009] In this technical solution, the upper surfaces of the first support plate, the second support plate, and the water receiving tray enclose a receiving cavity for placing and installing a drainage pump. In this way, it is convenient to disassemble and install the drainage pump and the mounting bracket, and thus it is convenient to install and disassemble the entire drainage pump assembly and the water receiving tray.

[0010] Further, the drainage pump is fixedly connected to the top plate, and the drainage pump abuts against the first support plate and the second support plate respectively.

[0011] In this technical solution, screw holes are provided on the top plate, so that the drainage pump is connected to the top plate by means of screws. In this way, it is convenient to disassemble and install the drainage pump and the mounting bracket, and thus it is convenient to install and disassemble the entire drainage pump assembly and the water receiving tray. The two side surfaces of the drainage pump can abut against the first support plate and the second support plate, so that the drainage pump is more stable during operation.

[0012] Further, the drainage pump assembly further includes a float switch, and the float switch is located in the receiving groove.

[0013] In this technical solution, the drainage pump assembly has a float switch capable of detecting the water level. The float switch is located in the receiving groove to be able to detect the water level in the receiving groove, so as to quickly drain water according to the water level situation and avoid water leakage.

[0014] Further, the bottom surface of the receiving groove is inclined, and the form of the inclined setting is that it gradually moves away from the calibration reference surface from one end of the bottom surface to the other end. The drainage pump assembly is located at the end of the bottom surface close to the calibration reference surface.

[0015] In this technical solution, the drainage pump assembly can be located at a lower position in the receiving groove, so that after the condensed water converges, the condensed water can be drained more accurately and quickly.

[0016] Further, the water receiving tray includes a water outlet nozzle, the water outlet nozzle is communicated with the receiving groove, and the water inlet of the water outlet nozzle is located at the end of the bottom surface close to the calibration reference surface. The water outlet of the drainage pump assembly is adapted to be communicated with the water inlet of the water outlet nozzle.

[0017] In this technical solution, through the setting of the water outlet nozzle and its communication with the drainage pump assembly, the condensed water in the receiving groove can be drained quickly.

[0018] The present invention also provides an air conditioner, including the drainage device described above.

[0019] The beneficial effects of the air conditioner in this technical solution and the above drainage device are similar to those in the prior art, and will not be elaborated here.

[0020] Furthermore, the air conditioner includes an air conditioner body and a middle partition arranged in the air conditioner body, the drainage device is movably arranged in the air conditioner body, a clearance gap is provided on the middle partition, and the drainage pump assembly of the drainage device matches the shape of the clearance gap.

[0021] In the present technical solution, a clearance gap is provided on the middle partition to avoid interference of the middle partition with the drainage pump assembly of the drainage device when the drainage device is disassembled. Therefore, during disassembly and installation, there is no need to disassemble the middle partition first, thereby improving work efficiency. At the same time, since the middle partition can be avoided from being disassembled, during the actual air conditioner maintenance process, the middle partition can maintain its supporting role on the air conditioner body, thereby improving the internal structural strength of the air conditioner and avoiding deformation.

[0022] Furthermore, it also includes a sealing baffle, which is suitable for covering the clearance gap.

[0023] In this technical solution, a sealing baffle is provided to cover the clearance gap, so as to avoid air leakage from the clearance gap, improve the sealing, and thus make the heat exchange effect of the heat exchanger better. When the drainage device needs to be disassembled or installed, the sealing baffle can be removed or moved to provide clearance for the drainage pump assembly. After the installation is completed, the sealing baffle is installed or moved to cover and seal the clearance gap.

[0024] Furthermore, the air conditioner includes a volute assembly, the volute assembly includes the sealing baffle and a volute arranged on the sealing baffle, and the sealing baffle is suitable for fitting with the middle partition.

[0025] In this technical solution, a sealing baffle is provided on the volute assembly to seal the clearance gap. When the drainage device is disassembled, the volute assembly is first disassembled from the return air inlet in accordance with the overall disassembly order of the air conditioner, and then the clearance gap can be opened, thereby facilitating the subsequent disassembly of the drainage device. After the drainage device is installed, only the volute assembly needs to be subsequently installed to seal the clearance gap, thereby improving the disassembly and installation efficiency of the air conditioner.

DETAILED DESCRIPTION

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] At the same time, it should be noted that the terms "first," "second," and the like in the description and claims of the present invention and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, such that the embodiments of the present invention described herein can be implemented in an order other than that illustrated or described herein.

[0035] Reference Figure 1 As shown, the present invention proposes a drainage device, including a water receiving tray 1 and a drainage pump assembly 2, wherein a receiving groove 101 is formed on the water receiving tray 1, and the drainage pump assembly 2 is connected to the water receiving tray 1, and the drainage pump assembly 2 is at least partially located in the receiving groove 101.

[0036] In the related art, the position of the water pump in the air conditioner is fixed. In this case, when the water tray is disassembled, the water pump will interfere with the movement of the water tray, so that the water tray cannot be directly moved and disassembled.

[0037] In this embodiment, a drainage device is proposed, which includes a water receiving tray 1. In actual use, the drainage device as a whole can be movably arranged inside an air conditioner such as a ducted air conditioner. Figure 5As shown, in a certain position state of the drainage device, the drainage device is located below the heat exchanger 6 of the duct unit as a whole, so that the water receiving pan 1 can receive the condensed water generated by the heat exchanger 6, thereby preventing the condensed water from affecting the operation of the air conditioner. A drainage pump assembly 2 is provided. Specifically, the drainage pump assembly 2 can be fixedly connected to the water receiving pan by bolt clamping. On the one hand, the drainage pump assembly 2 can cooperate with the water receiving pan 1. After the water receiving pan 1 receives a certain amount of condensed water, the condensed water can be quickly drained through the drainage pump assembly 2, thereby quickly draining the condensed water. The condensed water can be drained away quickly, wherein the drain pump assembly 2 is fixedly connected to the water receiving pan 1, so that the drain pump assembly 2 can move with the water receiving pan 1. When the water receiving pan 1 needs to be disassembled and cleaned, the drain pump assembly 2 will not interfere with the water receiving pan 1 due to the positional relationship between the drain pump assembly 2 and the water receiving pan 1. When installing the water receiving pan 1, there is no need to deliberately adjust the position of the drain pump assembly 2. After the installation of the water receiving pan 1 is completed, the position of the drain pump assembly 2 can be moved or the subsequent installation steps can be performed, so as to facilitate the disassembly and assembly of the water receiving pan 1 in the air conditioner. The trough 101 and the trough-shaped structure can have a certain accommodating space, so that it can have a certain water receiving and storage capacity, and avoid the condensed water from spilling out after the water is received and stored, and the drain pump assembly 2 is at least partially located in the accommodating groove 101. In this way, on the one hand, the part of the drain pump assembly 2 located in the accommodating groove 101 can be close to the condensed water, thereby achieving a better pumping and drainage effect. At the same time, when the entire drainage device is disassembled and installed, the drain pump assembly 2 of the drainage device is simultaneously active. At this time, for example, inside the air conditioner of the duct machine, the drain pump assembly 2 may cause interference and collision with the internal structure of the duct machine, which also causes problems such as inconvenience in disassembly and installation. Therefore, the drain pump assembly 2 is at least partially located in the accommodating groove 101. At this time, because the accommodating groove 101 has a certain accommodating space, after accommodating the drain pump assembly 2, the height of the overall structure of the drainage device can be made lower, and interference that is not conducive to disassembly and installation can be avoided as much as possible. In an optional embodiment, based on the structure of the drain pump assembly 2, the drain pump assembly 2 can be located in the accommodating groove 101 as a whole, so as to better facilitate disassembly and installation.

[0038] In an optional embodiment of the present invention, the drain pump assembly 2 includes a mounting bracket 201 and a drain pump 202 disposed on the mounting bracket 201 , and the mounting bracket 201 is fixedly connected to the water receiving tray 1 .

[0039] Reference Figure 2 and 3As shown, in this embodiment, the drainage pump assembly 2 includes a drainage pump 202, and rapid drainage is carried out through the drainage pump 202. Specifically, the drainage pump 202 is fixedly installed on the water receiving tray 1 through a mounting bracket 201, so that the drainage pump 202 and the entire drainage pump assembly 2 can move together with the water receiving tray 1 as a whole, which facilitates the disassembly and assembly of the water receiving tray 1 during actual use. Among them, setting the mounting bracket 201 can also facilitate the fixed installation and disassembly of the drainage pump 202 and make the fixation of the drainage pump 202 more stable.

[0040] In an alternative embodiment of the present invention, the mounting bracket 201 includes a top plate 2011 and relatively arranged first and second support plates 2012 and 2013. The first support plate 2012 and the second support plate 2013 are connected to the water receiving tray 1. The top plate 2011 is located between the first support plate 2012 and the second support plate 2013 and is respectively connected to the first support plate 2012 and the second support plate 2013. An accommodation cavity 3 is formed by the top plate 2011, the first support plate 2012, the second support plate 2013 and the water receiving tray 1, and the drainage pump 202 is located in the accommodation cavity 3.

[0041] [[ID=**6**]]Refer to Figure 2 As shown, in this embodiment, the mounting bracket 201 can be fixedly arranged on the water receiving tray 1 through connection methods such as clamping and screwing. Specifically, the two opposite first support plate 2012 and the second support plate 2013 of the mounting bracket 201 are fixedly connected to the water receiving tray 1, and can be fixedly connected specifically through forms such as screws, buckles or welding. A top plate 2011 is arranged between the first support plate 2012 and the second support plate 2013, and both ends of the top plate 2011 are respectively connected to the first support plate 2012 and the second support plate 2013. Specifically, the top plate 2011, the first support plate 2012 and the second support plate 2013 can be integrally formed. At this time, based on the shape of the mounting bracket 201, an accommodation cavity 3 for placing and installing the drainage pump 202 is formed by the upper surfaces of the first support plate 2012, the second support plate 2013 and the water receiving tray 1. Among them, the drainage pump 202 can be provided with a structure having a mating connector, such as a mounting plate with a threaded hole, for mating installation with the first support plate 2012 or the second support plate 2013 or the top plate 2011.

[0042] In an alternative embodiment of the present invention, the drainage pump 202 is fixedly connected to the top plate 2011, and the drainage pump 202 abuts against the first support plate 2012 and the second support plate 2013 respectively.

[0043] In this embodiment, screw holes are provided on the top plate 2011, so that the drainage pump 202 is connected to the top plate 2011 by screws. In this way, it is convenient to disassemble and install the drainage pump 202 and the mounting bracket 201, and thus it is convenient to install and disassemble the entire drainage pump assembly 2 and the water receiving tray 1. The two side surfaces of the drainage pump 202 can be abutted against the first support plate 2012 and the second support plate 2013, so that the drainage pump 202 is more stable during operation.

[0044] In an alternative embodiment of the present invention, the drainage pump assembly 2 further includes a float switch 203, and the float switch 203 is located in the receiving groove 101.

[0045] Refer to Figure 2 and 3 As shown, in this embodiment, the drainage pump assembly 2 has a float switch 203 capable of detecting the water level. The float switch 203 can use the magnetic float on the switch to rise or fall with the liquid level, so that the reed switch chip at a set position in the switch detection tube acts to send an on or off switch signal. The float switch 203 is located in the receiving groove 101 to be able to detect the water level in the receiving groove 101, so as to quickly drain water according to the water level situation and avoid water leakage. In actual use, the float switch 203 can be selectively electrically connected to the drainage pump 202 or to the control system of the air conditioner to perform quick drainage control according to the water level situation after detecting the water level. In this embodiment, the float switch 203 is provided on the mounting bracket 201 by bolts to facilitate the disassembly and assembly of the float switch 203.

[0046] In an alternative embodiment of the present invention, the bottom surface of the receiving groove 101 is inclined, and the form of the inclined setting is that it gradually moves away from the calibration reference surface from one end of the bottom surface to the other end, and the drainage pump assembly 2 is located at the end of the bottom surface close to the calibration reference surface.

[0047] Refer to Figure 2As shown, in this embodiment, the receiving groove 101 is used to receive condensed water, and the bottom surface of the groove is inclined. In this embodiment, the calibration reference plane is the horizontal plane. When the water receiving tray 1 receives condensed water, the condensed water will converge due to gravity. When the water receiving tray 1 is placed horizontally, the receiving groove 101 of the water receiving tray 1 has a region with a lower height relative to other regions of the receiving groove 101. Among them, the end of the bottom surface of the groove close to the calibration reference plane is the region with a lower height. Relatively, other regions of the bottom surface of the groove, especially the other end far from the calibration reference plane, are the regions with a higher height. When the air conditioner is actually in use, after the water receiving tray 1 receives condensed water, the condensed water will flow under the action of gravity, so as to converge towards the lower region, that is, towards the end of the bottom surface of the groove close to the calibration reference plane. In this embodiment, the drainage pump assembly 2 can be located at the end of the bottom surface of the groove close to the calibration reference plane, so as to drain the condensed water more accurately and quickly after the condensed water converges.

[0048] In one embodiment, the water inlet of the drainage pump assembly 2, specifically, the drainage pump 202 has a water inlet, and this water inlet is directly located at the end of the bottom surface of the groove close to the calibration reference plane, so that after the receiving groove 101 converges the water flow, it can pump water through the water inlet, so as to drain the condensed water more quickly.

[0049] In an optional embodiment of the present invention, the water receiving tray 1 includes a water outlet nozzle 103, the water outlet nozzle 103 is communicated with the receiving groove 101, and the water inlet of the water outlet nozzle 103 is located at the end of the bottom surface of the groove close to the calibration reference plane, and the water outlet of the drainage pump assembly 2 is adapted to be communicated with the water inlet of the water outlet nozzle 103.

[0050] Refer to Figure 2 As shown, in this embodiment, the water receiving tray 1 includes a water outlet nozzle 103 for draining the received condensed water. When the water receiving tray 1 is applied to an air conditioner, in the actual production of the air conditioner, the water outlet nozzle 103 can be connected to a pipeline to facilitate drainage. Among them, the water outlet nozzle 103 is communicated with the receiving groove 101, so as to be able to discharge water from the receiving groove 101. Specifically, the water inlet of the water outlet nozzle 103 is an opening formed on the receiving groove 101, and at the same time, the water inlet of the water outlet nozzle 103 is located at the end of the bottom surface of the groove close to the calibration reference plane, so as to facilitate and quickly discharge water from the receiving groove 101. Among them, the water outlet of the drainage pump assembly 2 can be communicated with the water inlet of the water outlet nozzle 103, so as to be able to discharge water quickly through the drainage pump assembly 2. Specifically, the water outlet of the drainage pump assembly 2 can be directly connected to the water inlet of the water outlet nozzle 103 to form a communication.

[0051] The present invention also proposes an air conditioner, including the drainage device described above.

[0052] The beneficial effects of the air conditioner and the drainage device of the present invention are similar to those of the prior art, and will not be elaborated here.

[0053] In an alternative embodiment of the present invention, the air conditioner includes an air conditioner body 4 and a middle partition 5 disposed inside the air conditioner body 4. The drainage device is movably disposed inside the air conditioner body 4. A relief notch 501 is provided on the middle partition 5, and the drainage pump assembly 2 of the drainage device matches the shape of the relief notch 501.

[0054] In this embodiment, referring to Figure 4 and 5 , the air conditioner can be an air duct machine. The air conditioner includes an air conditioner body 4 to perform actual heating and cooling operations. A middle partition 5 is disposed inside the air conditioner body 4. Usually, the middle partition 5 is disposed in the middle of the air conditioner body 4 to support the air conditioner body 4 and separate the heat exchanger 6 and the volute assembly inside the air conditioner body 4. Usually, the water receiving tray 1 in the drainage device is located below the heat exchanger 6 to receive condensed water. Among them, the drainage device is movably disposed inside the air conditioner body 4 to enable disassembly and assembly of the drainage device. Specifically, when disassembling the drainage device, the drainage device can move in the Figure 5 middle right direction for disassembly. When installing the drainage device, the drainage device can move in the Figure 5 middle left direction for installation, so that the water receiving tray 1 of the drainage device is located below the heat exchanger 6. When disassembling and assembling the internal structure of the air conditioner, it is usually disassembled and assembled from the air return opening of the air conditioner. Specifically, referring to Figure 5 , the air outlet of the air conditioner is located on the left side of the middle partition 5, and the air return opening of the air conditioner is located on the right side of the middle partition 5 and faces downward. Among them, in the installed state, the water receiving tray 1 is located below the heat exchanger 6 on the left side of the middle partition 5. Therefore, referring to Figure 4 as shown, a relief notch 501 is provided on the middle partition 5, and the shape of the relief notch 501 matches the shape of the drainage pump assembly 2. Specifically, the cross-sections of the relief notch 501 and the drainage pump assembly 2 are both approximately rectangular, and the size of the relief notch 501 is slightly larger than that of the drainage pump assembly 2 to prevent the middle partition 5 from interfering with the drainage pump assembly 2 of the drainage device when disassembling the drainage device. Therefore, when disassembling and installing, it is not necessary to first disassemble the middle partition 5, thereby improving work efficiency. At the same time, since it is possible to avoid disassembling the middle partition 5, during the actual maintenance of the air conditioner, the middle partition 5 can maintain the supporting effect on the air conditioner body 4, thereby improving the internal structure strength of the air conditioner and preventing deformation.

[0055] In an alternative embodiment of the present invention, a sealing baffle is further included, and the sealing baffle is adapted to cover the relief notch 501.

[0056] In this embodiment, a sealing baffle is provided to cover the clearance gap 501, so as to avoid air leakage from the clearance gap 501 and improve the sealing, thereby making the heat exchange effect of the heat exchanger 6 better. When the drainage device needs to be disassembled or installed, the sealing baffle can be disassembled or moved to provide clearance for the drainage pump assembly 202. After the installation is completed, the sealing baffle is installed or moved to cover and seal the clearance gap 501.

[0057] In an optional embodiment of the present invention, the air conditioner includes a volute assembly 7, the volute assembly 7 includes the sealing baffle 701 and a volute 702 arranged on the sealing baffle 701, and the sealing baffle 701 is suitable for fitting with the middle partition 5.

[0058] Reference Figure 6 As shown, in this embodiment, a sealing baffle 701 is provided on the volute assembly 7 of the air conditioner, wherein the volute 702 of the volute assembly 7 is provided on the sealing baffle 701 and forms the volute assembly 7 as a whole with the sealing baffle 701, so as to facilitate installation and disassembly, wherein the sealing baffle 701 is suitable for fitting with the middle partition 5, and an opening is opened on the middle partition 5 to facilitate the air guidance of the volute 702. After the sealing baffle 701 is fitted with the middle partition 5, the volute assembly 7 is installed as a whole, and a mask seal is formed for the clearance gap 501. When disassembling the drainage device, according to the disassembly order of the entire air conditioner, the volute assembly 7 is first disassembled as a whole from the return air inlet, and then the clearance gap 501 can be opened, thereby facilitating the subsequent disassembly of the drainage device. After the drainage device is installed, only the volute assembly 7 needs to be subsequently installed to seal the clearance gap 501, thereby improving the disassembly and installation efficiency of the air conditioner.

[0059] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
