Description

Technical Field

[0001] The present application relates to the field of air conditioning drainage, and in particular to a drainage structure and a tower air conditioner. Background Art

[0002] Tower air conditioner is a new type of air conditioning equipment. Its working principle is to use water circulation and cold air convection to regulate indoor temperature and humidity. Compared with traditional air conditioners, tower air conditioner fans are more energy-saving and environmentally friendly, and are relatively cheap and more convenient to use.

[0003] In the related art, condensed water generated by tower air conditioners is collected in a chassis located at the bottom of the tower air conditioner. When the chassis is full of condensed water, it is necessary to promptly unplug the chassis to drain the water. However, in actual use, since the chassis is located at the bottom of the tower air conditioner, it is inconvenient to unplug the chassis, resulting in inconvenient drainage of the tower air conditioner. Therefore, improvements are needed. Utility Model Content

[0004] In order to facilitate drainage of a tower air conditioner, in a first aspect, the present application provides a drainage structure.

[0005] The drainage structure provided in this application adopts the following technical solution:

[0007] By adopting the above technical solution, in actual application, when the water collection tank of the chassis is full of condensed water, the submersible pump works to transport the condensed water in the water collection tank to the drainage tank, and then the water retaining head is removed from the main drainage head, so that the condensed water in the drainage tank is discharged through the main drainage head. Since the downwind duct shell is located above the chassis, the water retaining head is at a certain distance from the ground, which makes it easy to remove the water retaining head from the main drainage head, thereby facilitating the drainage of the tower air conditioner.

[0008] Preferably, the downwind duct shell is provided with a return channel in the vertical direction, the upper end of the return channel is higher than the drainage groove, and the return channel is communicated with the water collecting groove.

[0009] By adopting the above technical solution and setting up a reflux channel, the submersible pump works continuously to continuously transport the condensed water in the sump to the drain trough. At the same time, the water retaining head is not removed, so that the condensed water in the drain trough overflows into the downwind duct shell and can flow back to the sump through the reflux channel. During the reflux process, the condensed water can flow down through the condenser, thereby improving the cooling effect and increasing energy efficiency.

[0010] Preferably, the downwind duct shell is provided with a guide groove on the bottom wall of the drainage groove, and the guide groove is communicated with the main drainage head.

[0011] By adopting the above technical solution, a guide groove is set to guide the condensed water in the drainage groove to the main drainage groove, so as to improve the drainage efficiency.

[0012] Preferably, the water retaining head is threadedly connected to the main drainage head.

[0013] By adopting the above technical solution, the water retaining head is threadedly connected to the main drainage head to achieve a detachable connection of the water retaining head, which has a simple structure and is easy to operate.

[0014] Preferably, a plurality of anti-slip protrusions are provided on the outer peripheral side of the water retaining head, and the plurality of anti-slip protrusions are evenly spaced along the circumference of the water retaining head.

[0015] By adopting the above technical solution and providing a plurality of anti-skid protrusions, the water retaining head can be easily rotated, thereby facilitating the installation and removal of the water retaining head.

[0016] Preferably, an auxiliary drainage head is provided on one side of the chassis, the auxiliary drainage head is communicated with the water collecting tank and is detachably connected to a water plug at one end away from the chassis.

[0017] By adopting the above technical solution and providing an auxiliary drainage head, when the tower air conditioner is powered off, the auxiliary drainage head can be removed to drain the condensed water in the chassis.

[0018] Preferably, both ends of the water collecting tank are higher than the middle portion, and the auxiliary drainage head is located on one side of the middle portion of the water collecting tank.

[0019] By adopting the above technical solution, by setting the two ends of the water collecting tank higher than the middle part, the condensed water in the water collecting tank can be discharged from the auxiliary drainage head under the action of the gravity of the condensed water.

[0020] In a second aspect, the present application provides a tower air conditioner.

[0021] The tower air conditioner provided in this application adopts the following technical solution:

[0022] A tower air conditioner comprises the drainage structure described above.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. In actual application, when the water collection tank of the chassis is full of condensed water, the submersible pump works to transport the condensed water in the water collection tank to the drainage tank. Then the water retaining head is removed from the main drainage head, so that the condensed water in the drainage tank is discharged through the main drainage head. Since the downwind duct shell is located above the chassis, the water retaining head is at a certain distance from the ground, which makes it easy to remove the water retaining head from the main drainage head, thereby facilitating the drainage of the tower air conditioner.

[0025] 2. By setting up a reflux channel, the submersible pump works continuously to continuously transport the condensed water in the sump to the drain tank. At the same time, the water retaining head is not removed, so that the condensed water in the drain tank overflows into the downwind duct shell and can flow back to the sump through the reflux channel. During the reflux process, the condensed water can flow down through the condenser, thereby improving the cooling effect and increasing energy efficiency.

[0026] 3. By setting up an auxiliary drainage head, when the tower air conditioner is powered off, the condensed water in the chassis can be drained by removing the auxiliary drainage head. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned figure descriptions are intended to cover non-exclusive inclusions.

[0033] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] The following is combined with Figure 1-4 This application is described in further detail.

[0035] An embodiment of the present application discloses a drainage structure.

[0036] Reference Figure 1 and Figure 2 The drainage structure includes a chassis 1, a downwind duct shell 2 and a submersible pump 3. The upper end of the chassis 1 has a water collection tank 11. The downwind duct shell 2 is located directly above the chassis 1. The upper end of the downwind duct shell 2 has a drainage tank 21, and a main drainage head 22 is formed on one side of the downwind duct shell 2. One end of the main drainage head 22 is connected to the drainage tank 21, and the other end is connected to the outside. At the same time, the end of the main drainage head 22 away from the downwind duct shell 2 is detachably connected to a water retaining head 23. The submersible pump 3 is fixedly connected to the upper end of the chassis 1. The water inlet end of the submersible pump 3 is connected to the water collection tank 11 through a connecting pipe (not marked in the figure), and the water outlet end of the submersible pump 3 is connected to the drainage tank 21 through a connecting pipe.

[0037] In actual application, when the water collection tank 11 of the chassis 1 is full of condensed water, the submersible pump 3 works to transport the condensed water in the water collection tank 11 to the drainage tank 21, and then the water retaining head 23 is removed from the main drainage head 22, so that the condensed water in the drainage tank 21 is discharged through the main drainage head 22. Since the downwind duct shell 2 is located above the chassis 1, the water retaining head 23 is at a certain distance from the ground, which facilitates the removal of the water retaining head 23 from the main drainage head 22, thereby facilitating the drainage of the tower air conditioner.

[0038] Reference Figure 2 In some embodiments, the downwind housing 2 is provided with a return channel 24 along the vertical direction. The return channel 24 is located on one side of the drain trough 21, and the upper end of the return channel 24 is higher than the drain trough 21. The return channel 24 is also connected to the sump 11 through the condenser of the tower air conditioner (not shown). When the submersible pump 3 continues to operate to continuously transport the condensed water in the sump 11 to the drain trough 21, and the water retaining head 23 is not removed, the condensed water in the drain trough 21 overflows into the downwind housing 2. Once the condensed water level is higher than the upper end of the return channel 24, the condensed water can flow back through the return channel 24 to the sump 11. During the return process, the condensed water can flow down through the condenser, thereby improving the cooling effect and increasing energy efficiency.

[0039] In some embodiments, the bottom wall of the downwind duct shell 2 is recessed to form a semicircular guide groove 25 located in the drainage groove 21. The guide groove 25 is connected to the main drainage head 22. The condensed water in the drainage groove 21 can flow into the main drainage head 22 under the guidance of the guide groove 25 to improve the drainage efficiency.

[0040] In some embodiments, the water retaining head 23 is threadedly connected to the main drainage head 22 to achieve a detachable connection between the water retaining head 23 and the main drainage head 22. The water retaining head 23 can be installed and removed by rotating the water retaining head 23, which has a simple structure and is easy to operate. Of course, in other embodiments, the water retaining head 23 can be detachably connected by plugging, snapping, etc., and this application is not limited thereto.

[0041] In some embodiments, a plurality of anti-slip protrusions 231 are protruded from the outer peripheral side of the water retaining head 23, and the plurality of anti-slip protrusions 231 are evenly spaced along the peripheral side of the water retaining head 23. When the staff rotates the water retaining head 23, the staff contacts the plurality of anti-slip protrusions 231 to increase the contact area with the water retaining head 23, thereby facilitating the rotation of the water retaining head 23, and further facilitating the installation and disassembly of the water retaining head 23.

[0042] Reference Figure 3 In some embodiments, a secondary drain head 12 is formed protruding from one side of the chassis 1. One end of the secondary drain head 12 is connected to the water collection tank 11, and the other end of the secondary drain head 12 is connected to the outside world. A water plug 13 is detachably connected to the end of the secondary drain head 12 away from the chassis 1. The water plug 13 can be detachably connected to the secondary drain head 12 by, but not limited to, plugging, snapping, or threading. This application is not limited thereto. When the tower air conditioner is powered off, the condensed water in the chassis 1 can be drained by removing the secondary drain head 12.

[0043] In some embodiments, the two ends of the water collection tank 11 are higher than the middle part, so that the cross-section of the water collection tank 11 is set in a "V" shape, and the auxiliary drainage head 12 is located on one side of the middle part of the water collection tank 11. Under the action of gravity, the condensed water in the water collection tank 11 flows from the two ends to the middle part, so as to facilitate the discharge of the condensed water in the water collection tank 11 from the auxiliary drainage head 12.

[0044] The implementation principle of this embodiment is: in actual application, when the water collection tank 11 of the chassis 1 is full of condensed water, the submersible pump 3 works to transport the condensed water in the water collection tank 11 to the drainage tank 21, and then the water retaining head 23 is disassembled from the main drainage head 22, so that the condensed water in the drainage tank 21 is discharged through the main drainage head 22. Since the downwind duct shell 2 is located above the chassis 1, the water retaining head 23 is at a certain distance from the ground, which facilitates the disassembly of the water retaining head 23 from the main drainage head 22, thereby facilitating the drainage of the tower air conditioner.

[0045] The embodiment of the present application also discloses a tower air conditioner.

[0046] Reference Figure 4 The tower air conditioner includes the drainage structure described in the above embodiment, the chassis 1 is located at the bottom of the tower air conditioner, and the downwind duct shell 2 is located in the middle part of the tower air conditioner.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
