Description

Technical Field

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

[0002] Compared with traditional floor-standing air conditioners or wall-mounted air conditioners, mobile air conditioners are compact in size, require no installation, are easy to move, and can be placed in different locations indoors according to user needs. They are flexible and convenient to use and are therefore popular among users.

[0003] In the prior art, the condensed water generated by the evaporator of the mobile air conditioner is collected in the water storage area on the chassis and consumed by the water pumping structure, which can not only cool the condenser assembly and improve the energy efficiency of the air conditioning system, but also save the trouble of users pouring condensed water. When the air humidity is relatively high, since the speed of condensed water generation is usually greater than the speed of consumption by the water pumping structure inside the air conditioner, in order to prevent excessive condensed water from being generated and the water pumping structure from consuming it in time, causing the condensed water to overflow the chassis and bring inconvenience to the user, a water level warning device is usually set in the chassis to monitor and warn the water level in the chassis. Since the first water storage area where the water pumping structure is located is connected to the second water storage area where the water level warning device is located, when the water pumping structure is working, the water in the first water storage area will flow to the second water storage area, causing the water level in the second water storage area to fluctuate. When the water level is relatively low, the impact on the water level warning device is not significant. As the water level rises, the fluctuation of the water level will increase, causing the float of the water level switch to jump up and down, resulting in the failure of the warning, and the failure to normally feedback the warning water level. Summary of the invention

[0004] In order to solve the above technical problems, the first aspect of the present invention provides a chassis structure, comprising a first water storage area, wherein a water pumping structure is arranged in the first water storage area;

[0005] a second water storage area, wherein a water level early warning device is provided in the second water storage area;

[0006] a water trough, the water trough being arranged between the first water storage area and the second water storage area, and being used for connecting the first water storage area and the second water storage area;

[0007] There are multiple water retaining ribs, and the multiple water retaining ribs are staggered along the axis of the water channel.

[0008] The present invention increases the flow resistance of condensed water flowing from the first water storage area to the second water storage area, reduces the speed of condensed water flowing from the first water storage area to the second water storage area, reduces the water level fluctuation in the second water storage area, and improves the accuracy of the water level warning device for the water level in the chassis.

[0009] Furthermore, adjacent water retaining ribs have no overlapping surfaces along a projection plane parallel to the cross section of the water channel.

[0010] The present invention reduces the impact on the effective width of the water channel by arranging adjacent water retaining ribs to have no overlapping surfaces along the projection surface parallel to the cross section of the water channel, thereby preventing the speed of condensed water from flowing back from the second water storage area to the first water storage area from being reduced.

[0011] Furthermore, one end of the water retaining rib is connected to the side wall of the water channel, and the other end of the water retaining rib stops at the center line of the water channel.

[0012] The present invention limits one end of the water retaining rib to stop at the center line of the water trough. On the one hand, it ensures the effective width of the water trough. On the other hand, it causes the water flow passing through the water trough to collide and rub against the staggered water retaining ribs, thereby reducing the water flow speed from the first water storage area to the second water storage area, reducing the water level fluctuation in the second water storage area, and improving the accuracy of the water level warning device for the water level in the chassis.

[0013] Furthermore, the water retaining rib includes a connecting portion and a bending portion, the first end of the connecting portion is connected to the side wall of the water channel, the second end of the connecting portion is connected to the first end of the bending portion, and the bending direction of the bending portion is toward the first water storage area.

[0014] The present invention adopts the method of bending the water retaining ribs in the direction of the first water storage area. On the one hand, it can increase the flow resistance of condensed water flowing from the first water storage area to the second water storage area, reduce the speed of condensed water flowing from the first water storage area to the second water storage area, reduce the water level fluctuation in the second water storage area, and improve the accuracy of the water level warning device for the water level in the chassis; on the other hand, it ensures the smoothness of the condensed water flowing back from the second water storage area to the first water storage area, ensures timely water return, and provides sufficient water for the water pumping structure.

[0015] Furthermore, the connecting portion is perpendicular to the side wall of the water channel.

[0016] The invention is simple to manufacture by arranging the connection part of the water retaining rib to be perpendicular to the side wall of the water channel.

[0017] Furthermore, the bent portion stops at the central axis of the water channel.

[0018] The present invention increases the opening width of the water retaining rib by stopping the bending portion at the central axis of the water trough, which is conducive to the rapid return of condensed water from the second water storage area to the first water storage area, ensuring the water required by the water pumping structure, cooling the condenser, and improving the performance of the condenser.

[0019] Furthermore, the angle between the connecting portion and the bending portion is greater than or equal to 110° and less than or equal to 130°.

[0020] The present invention limits the angle between the connecting portion and the bending portion to a large rounded angle. On the one hand, it increases the resistance of condensed water flowing from the first water storage area to the second water storage area, reduces the speed of condensed water flowing from the first water storage area to the second water storage area, reduces the water level fluctuation in the second water storage area, and improves the accuracy of the water level warning device for the water level in the chassis; on the other hand, it provides guidance for the condensed water to flow back from the second water storage area to the first water storage area, reduces the condensed water return resistance, and ensures timely water return.

[0021] Furthermore, the spacing between the water retaining ribs on the same side is greater than or equal to 25 mm and less than or equal to 30 mm.

[0022] The present invention limits the spacing between adjacent water retaining ribs on the same side to a certain range, thereby ensuring the opening width of the water retaining ribs and reducing the surface tension of water, so that water can flow back smoothly from the second water storage area to the first water storage area, preventing water from accumulating in the second water storage area for a long time, preventing the generation of odor, and improving user comfort.

[0023] Furthermore, the water retaining reinforcement includes a first water retaining reinforcement, the side wall of the water trough includes a first side wall, the first side wall is close to the water pumping structure, the connecting part of the first water retaining reinforcement is connected to the first side wall, and the first water retaining reinforcement is used to block part of the water flowing from the first water storage area to the second water storage area.

[0024] The present invention arranges the first water retaining rib on the side close to the water pumping structure to better block the large fluctuation of water flow in the first water storage area, reduce the speed of the water flow, and realize the diversion of water in the first water storage area, with part of the water rebounding back to the first water storage area and part of it flowing to the second water storage area through the water flow trough.

[0025] Furthermore, the water retaining rib and the water trough are integrally formed.

[0026] The present invention adopts the method of integrally forming the water retaining rib and the water trough, which does not need to be manufactured separately, reduces the processing steps and has low cost.

[0027] A second aspect of the present invention provides an air conditioner, comprising the above-mentioned chassis structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following is a brief description of the present invention in conjunction with the attached drawings. Figure 1-6 The specific embodiments of the present invention are described in detail.

[0037] Condensed water is generated during the refrigeration operation of the mobile air conditioner, and the condensed water is collected in the water storage area on the chassis. The condenser (not shown) is located above the first water storage area 100 provided with the water pumping structure 110, and the water level warning device 210 is located in the second water storage area 200, and the first water storage area 100 is connected to the second water storage area 200. When the water pumping structure 110 is working, the water in the first water storage area 100 will flow into the second water storage area 200. When the water level in the second water storage area 200 is relatively high, the water level fluctuation in the second water storage area 200 will increase, and the float of the water level switch 211 of the water level warning device 210 will float up and down with the water level fluctuation, thereby affecting the warning performance of the water level warning device 210 and causing a false alarm.

[0038] See attached Figure 1 , a first aspect of the present invention provides a chassis structure 10, comprising a first water storage area 100, wherein a water pumping structure 110 is disposed in the first water storage area 100;

[0039] A second water storage area 200, wherein a water level warning device 210 is provided in the second water storage area 200;

[0040] A water channel 300, wherein the water channel 300 is disposed between the first water storage area 100 and the second water storage area 200, and is used to connect the first water storage area 100 and the second water storage area 200;

[0041] The water retaining ribs 310 are multiple in number and are staggeredly arranged along the axis of the water channel 300 .

[0042] See attached Figure 1 and 2 The water pumping structure 110 is used to sprinkle condensed water on the condenser, and the water pumping structure 110 includes a water pumping trough 112, a water pumping wheel 111 and a water pumping motor 113; the water pumping trough 112 is used to accumulate condensed water; the water pumping wheel 111 is at least partially accommodated in the water pumping trough 112, and sprinkles the accumulated condensed water in the water pumping trough 112 on the condenser; the water pumping motor 113 is connected to the water pumping wheel 111 to drive the water pumping wheel 111 to rotate.

[0043] See attached Figure 2 The water level warning device 210 includes a water level switch 211. When the water level of the second water storage area 200 rises to the warning water level, the water level switch 211 can be triggered to close and generate an alarm signal.

[0044] Therefore, the present invention increases the flow resistance of condensed water flowing from the first water storage area 100 to the second water storage area 200 by arranging staggered water retaining ribs 310 in the water flow channel 300 connecting the first water storage area 100 and the second water storage area 200, reduces the speed of condensed water flowing from the first water storage area 100 to the second water storage area 200, reduces the water level fluctuation of the second water storage area 200, and improves the accuracy of the water level warning device 210 for the water level in the chassis.

[0045] See attached Figure 1 , the adjacent water retaining ribs 310 have no overlapping surface along the projection plane parallel to the cross section of the water trough 300. It should be noted that the water retaining ribs 310 can be transverse ribs or non-transverse ribs. When the staggered water retaining ribs 310 have overlapping surfaces along the projection plane parallel to the cross section of the water trough 300, the effective water passing width of the water trough 300 is reduced, which is not conducive to the condensed water from the second water storage area 200 to the first water storage area 100, causing the condensed water to accumulate in the second water storage area 200 to produce odor, or causing insufficient water in the first water storage area 100.

[0046] Therefore, the present invention reduces the impact on the effective width of the water trough 300 and prevents the speed of condensation water from flowing back from the second water storage area 200 to the first water storage area 100 from being reduced by arranging adjacent water retaining ribs 310 without overlapping surfaces along the projection surface parallel to the cross section of the water trough 300.

[0047] See attached Figure 1 One end of the water retaining rib 310 is connected to the side wall of the water channel 300, and the other end of the water retaining rib 310 ends at the center line of the water channel 300. The lengths of the staggered water retaining ribs 310 are equal.

[0048] Therefore, the present invention limits one end of the water retaining rib 310 to stop at the center line of the water trough 300. On the one hand, it ensures the effective width of the water trough 300. On the other hand, it causes the water flow passing through the water trough 300 to collide and rub against the staggered water retaining ribs 310, thereby reducing the water flow speed flowing from the first water storage area 100 to the second water storage area 200, reducing the water level fluctuation in the second water storage area 200, and improving the accuracy of the water level warning device 210 for the water level in the chassis.

[0049] The water retaining ribs 310 may be transverse ribs or non-transverse ribs. When the water retaining ribs 310 are transverse ribs, the transverse ribs form right angles, which makes the surface tension of water relatively large, greatly reducing the flow rate of water. On the one hand, the flow rate of water from the first water storage area 100 to the second water storage area 200 is reduced, and the water level fluctuation of the second water storage area 200 is reduced; on the other hand, the flow rate of water from the second water storage area 200 to the first water storage area 100 is also reduced, which is likely to cause water shortage in the first water storage area 100 or long-term accumulation of water in the second water storage area 200 to produce odor.

[0050] Preferably, see Appendix Figure 3 The water retaining rib 310 includes a connecting portion 311 and a bending portion 312, the first end of the connecting portion 311 is connected to the side wall of the water channel 300, the second end of the connecting portion 311 is connected to the first end of the bending portion 312, and the bending direction of the bending portion 312 is toward the first water storage area 100.

[0051] Therefore, the present invention adopts the method of bending the water retaining rib 310 toward the first water storage area 100. On the one hand, it can increase the flow resistance of condensed water flowing from the first water storage area 100 to the second water storage area 200, reduce the speed of condensed water flowing from the first water storage area 100 to the second water storage area 200, reduce the water level fluctuation of the second water storage area 200, and improve the accuracy of the water level warning device 210 for the water level in the chassis; on the other hand, it ensures the smoothness of the condensed water flowing back from the second water storage area 200 to the first water storage area 100, ensures timely water return, and provides sufficient water for the water pumping structure 110.

[0052] Preferably, see Appendix Figure 3 The connecting portion 311 is perpendicular to the side wall of the water channel 300 .

[0053] Therefore, the present invention simplifies processing and manufacturing by arranging the connection part 311 of the water retaining rib 310 to be perpendicular to the side wall of the water channel 300.

[0054] Preferably, see Appendix Figure 3 The bending portion 312 ends at the central axis of the water channel 300 .

[0055] It should be noted that when the staggered water retaining ribs 310 exceed the center line of the water gutter 300 and the adjacent water retaining ribs 310 overlap in the projection surface parallel to the cross section of the water gutter, the opening width formed by the water retaining ribs 310 will be reduced, which is not conducive to the rapid backflow of condensed water.

[0056] Therefore, the present invention stops the bending portion 312 at the central axis of the water channel 300, increases the opening width of the water retaining rib 310, and facilitates the rapid return of condensed water from the second water storage area 200 to the first water storage area 100, ensures the water required by the water pumping structure 110, cools the condenser, and improves the performance of the condenser.

[0057] See attached Figure 4 , an angle θ between the connecting portion 311 and the bending portion 312 is greater than or equal to 110° and less than or equal to 130°.

[0058] Preferably, the angle θ between the connecting portion 311 and the bending portion 312 is 120°.

[0059] Therefore, the present invention limits the angle between the connecting portion 311 and the bending portion 312 to a large rounded angle. On the one hand, it increases the resistance of condensed water flowing from the first water storage area 100 to the second water storage area 200, reduces the speed of condensed water flowing from the first water storage area 100 to the second water storage area 200, reduces the water level fluctuation in the second water storage area 200, and improves the accuracy of the water level warning device 210 for the water level in the chassis; on the other hand, it provides guidance for the condensed water to flow back from the second water storage area 200 to the first water storage area 100, reduces the condensed water return resistance, and ensures timely water return.

[0060] See attached Figure 4 The spacing d between the adjacent water retaining ribs 310 on the same side is greater than or equal to 25 mm and less than or equal to 30 mm.

[0061] Therefore, the present invention limits the spacing between adjacent water retaining ribs 310 on the same side to a certain range, thereby ensuring the opening width of the water retaining ribs 310 and reducing the surface tension of water, allowing water to flow back smoothly from the second water storage area 200 to the first water storage area 100, preventing water from accumulating in the second water storage area 200 for a long time, preventing the generation of odor, and improving user comfort.

[0062] Preferably, the thickness of the water retaining rib 310 is greater than or equal to 1 mm and less than or equal to 2 mm.

[0063] Preferably, see Appendix Figure 4 The water retaining rib 310 includes a first water retaining rib 3101, which is arranged on a first side wall 3011 of the water trough 300, and the first side wall 3011 is close to the water pumping structure 110. The first water retaining rib 3101 is used to block part of the water flowing from the first water storage area 100 to the second water storage area 200.

[0064] Therefore, the present invention arranges the first water retaining rib 3101 on the side close to the water pumping structure 110 to better block the large fluctuations of the water flow in the first water storage area 100, reduce the speed of the water flow, and achieve diversion of the water in the first water storage area 100, with part of the water rebounding back to the first water storage area 100 and part of it flowing to the second water storage area 200 through the water trough 300.

[0065] In this embodiment, see the attached Figure 4 The number of the water retaining ribs 310 is 3, and the water retaining ribs 310 include a first water retaining rib 3101, a second water retaining rib 3102 and a third water retaining rib 3103, wherein the second water retaining rib 3102 is located between the first water retaining rib 3101 and the third water retaining rib 3103, and the water channel 300 includes a first side wall 3011 and a second side wall 3012, wherein the first side wall 3011 is close to the water pumping structure 110, the first water retaining rib 3101 and the third water retaining rib 3103 are arranged on the first side wall 3011, and the second water retaining rib 3102 is arranged on the second side wall 3012.

[0066] See attached Figure 5, the single arrow represents the water flow from the first water storage area 100 to the second water storage area 200; the double arrow represents the water flow that rebounds back to the first water storage area 100. When the pumping structure 110 is working, the first water retaining rib 3101 is used to block the large fluctuation of the water flow in the first water storage area 100, reduce the speed of the water flow, and realize the diversion of the water in the first water storage area 100, part of which rebounds back to the first water storage area 100, and part of which flows to the second water storage area 200 through the water trough 300; the second water retaining rib 3102 and the third water retaining rib 3103 form a tortuous flow path in the water trough 300, when the condensed water flows from the first water storage area 100 to the second water storage area 2 At 00, the water that passes through the first water retaining rib 3101 and enters the water trough 300 is continuously colliding and rubbing against the second water retaining rib 3102, the third water retaining rib 3103, the first side wall 3011 and the second side wall 3012, causing the water flow velocity to drop sharply, and finally enters the second water storage area 200. At this time, the water surface fluctuation of the second water storage area 200 is within the normal range, so as not to affect the accuracy of the water level warning device 210 for the water level in the chassis.

[0067] See attached Figure 6 , a single arrow indicates the direction of water flow, and a double arrow indicates that the water flow collides and rubs against the water retaining rib or the side wall of the water trough. When the condensed water in the first water storage area 100 decreases or the user shuts down the machine to drain water, the condensed water flows back from the second water storage area 200 to the first water storage area 100. Since the opening direction of the water retaining rib 310 formed by the first water retaining rib 3101, the second water retaining rib 3102 and the third water retaining rib 3103 is consistent with the direction of condensed water backflow, the surface tension of water can be effectively reduced, so that the condensed water can flow back to the first water storage area 100 smoothly, preventing the condensed water from accumulating in the second water storage area 200, preventing the generation of odor, and improving the user's comfort.

[0068] The water retaining rib 310 and the water channel 300 may be integrally formed or separately formed. Preferably, the water retaining rib 310 and the water channel 300 are integrally formed.

[0069] Therefore, the present invention adopts the method of integrally forming the water retaining rib 310 and the water trough 300, which does not need to be manufactured separately, reduces the processing steps and has low cost.
