Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and more particularly, to a water level detection device and an air conditioner. Background Art

[0002] In the prior art, the water level detection of the ceiling air conditioner is a float switch, which mainly includes a floating ball, a bushing, and a Hall element. The floating ball can float up and down along the bushing. The Hall element is arranged inside the bushing, and a magnet is arranged inside the floating ball. When the liquid level in the water collecting tray of the ceiling air conditioner is low, the distance between the magnet and the Hall element is close, and the Hall element is turned on; when the liquid level in the water collecting tray of the ceiling air conditioner is high, the distance between the magnet and the Hall element is far, and the Hall element is turned off. In this way, the water level in the water collecting tray is judged, and the water pump is started or stopped to drain water accordingly.

[0003] However, in the actual construction process, there is such a problem: both the Hall element and the float switch are arranged inside the water collecting tray, and the signal wire needs to be led out from inside the water collecting tray, which will cause a gap between the water collecting tray and the chassis foam, thus there is a risk of air leakage. Summary of the Invention

[0004] Therefore, the embodiments of the present invention provide a water level detection device, which improves the sealing performance between the water collecting tray and the chassis foam.

[0005] To solve the above problems, the present invention provides a water level detection device, including: a chassis foam and a water collecting tray. The water level detection device includes: a water collecting cavity, which is arranged on the water collecting tray; a float switch, which is arranged inside the chassis foam and / or the water collecting tray, and the float switch communicates with the water collecting cavity; a detection component, which is arranged on the outer side of the water collecting tray away from the chassis foam; wherein, the float switch and the detection component are arranged opposite to each other.

[0006] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: Since the existing detection components are all arranged between the chassis foam and the water collecting tray, the signal wire needs to be led out from inside the water collecting tray, which will cause a risk of air leakage between the water collecting tray and the chassis foam, and the complex wiring leads to a high cost. In the present invention, the float switch is arranged inside the chassis foam and / or the water collecting tray, while the detection component is arranged on the outer side of the water collecting tray away from the chassis foam, so that the detection component can be wired from the outside of the water collecting tray, thereby improving the sealing performance between the chassis foam and the water collecting tray and preventing air leakage and other situations between the chassis foam and the water collecting tray.

[0007] In an example of the present invention, it further includes: a panel, which is arranged on one side of the water collecting tray away from the chassis foam; a fixing seat, which is provided with an accommodating cavity inside, and the fixing seat is arranged between the panel and the water collecting tray; a Hall element, which is arranged inside the accommodating cavity.

[0008] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By arranging the panel on the side of the water receiving tray away from the chassis foam, and there is a gap between the panel and the water receiving tray, and wiring is carried out through this gap, which can prevent the wire from contacting the sheet metal and generating abnormal noises, and is also convenient for wiring; By arranging the fixing seat between the panel and the water receiving tray, a gap is formed between the panel and the water receiving tray; and the Hall element is arranged in the accommodating cavity arranged on the fixing seat. By wiring through the gap between the panel and the water receiving tray, it can prevent the wire from contacting the sheet metal and generating abnormal noises, and is also convenient for wiring.

[0009] In an example of the present invention, the fixing seat includes: a plurality of limiting buckles, and the limiting buckles are arranged on the side of the fixing seat close to the panel; wherein, a plurality of buckle installation positions are arranged on the panel, and the limiting buckles and the buckle installation positions cooperate to install the fixing seat on the panel.

[0010] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By arranging a plurality of limiting buckles on the fixing seat and a plurality of buckle installation positions on the panel, through the cooperation of the plurality of limiting buckles and the plurality of buckle installation positions, the fixing seat is buckled on the panel, and a gap is formed between the panel and the water receiving tray.

[0011] In an example of the present invention, the fixing seat further includes: a guiding column, and the guiding column is arranged on the side of the fixing seat close to the panel; wherein, a guiding column installation position is arranged on the panel, and the guiding column and the guiding column installation position cooperate to enable the panel to move directionally on the fixing seat.

[0012] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By arranging the guiding column on the fixing seat and the guiding column installation position on the panel, through the cooperation of the guiding column and the guiding column installation position, the panel can move directionally on the fixing seat.

[0013] In an example of the present invention, the fixing seat further includes: an elastic member, and the elastic member is arranged on the guiding column.

[0014] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By arranging the elastic member on the guiding column, when the panel moves towards the side close to the water receiving tray, the elastic member is squeezed. When the panel is not pushed, the elastic force of the elastic member can be used to rebound the panel, so that the panel automatically resets; on the other hand, the elastic member can prevent the panel from directly contacting the water receiving tray, thereby damaging the circuit arranged between the panel and the water receiving tray.

[0015] In an example of the present invention, it further includes: a limiting sleeve, and the limiting sleeve is arranged on the chassis foam and / or the water receiving tray; wherein, the float switch is arranged in the limiting sleeve.

[0016] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: Since the existing float switch needs to embed a mounting bracket on the chassis foam, the structure is complex. Now, the limit sleeve is directly arranged on the chassis foam and / or the water receiving tray, and the float switch is arranged inside the limit sleeve, thereby reducing the complexity of the structure and facilitating the installation of the float switch.

[0017] In one example of the present invention, at least one rib is provided on the inner wall of the limit sleeve.

[0018] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By providing at least one rib inside the limit sleeve, the rib can reduce the movement resistance of the float switch, thereby ensuring that the float switch will not get stuck, and improving the detection accuracy.

[0019] In one example of the present invention, at least one water passing hole is provided on the limit sleeve.

[0020] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By providing at least one water passing hole on the limit sleeve, the inside of the limit sleeve is communicated with the water receiving tray. Through the rise or fall of the water level on the water receiving tray, the rise and fall of the float switch are controlled, thereby judging the height of the water level in the water receiving tray, and facilitating further control.

[0021] In one example of the present invention, the float switch includes: a float; a magnet, and the magnet is arranged on one side of the float close to the detection component.

[0022] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By providing a magnet on one side of the float close to the detection component, the float can float up and down along the limit sleeve, and a magnet is arranged inside the float. When the liquid level in the water receiving tray is low, the magnet is close to the Hall element, and the Hall element is turned on; when the liquid level in the water receiving tray is high, the magnet is far from the Hall element, and the Hall element is turned off.

[0023] In one example of the present invention, the float switch further includes: an end cover, and the end cover is arranged on one side of the float close to the detection component; wherein, the magnet is installed on one side of the float close to the detection component through the end cover.

[0024] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By providing an end cover on one side of the float close to the detection component, and the magnet is arranged inside the end cover. Since directly placing the magnet inside the float will lead to complex processing and a high rejection rate, the processing difficulty of the float switch is reduced by providing an end cover to fix the magnet.

[0025] On the other hand, an embodiment of the present invention further provides an air conditioner, including: a water level detection device as described in any one of the above embodiments.

[0026] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: by arranging a water level detection device on the air conditioner, the water level in the water receiving tray of the air conditioner can be detected through the water level detection device, so as to judge the height of the water level in the water receiving tray, and then start or stop the water pump for drainage.

[0027] After adopting the technical solution of the present invention, the following technical effects can be achieved:

[0028] (1) By arranging the float switch inside the chassis foam and / or the water receiving tray, and the detection component is arranged on the side of the water receiving tray away from the chassis foam, and the detection component and the water receiving tray are in mutual contact, so that the detection component can be routed from the outside of the water receiving tray, thereby improving the sealing performance of the chassis foam and the water receiving tray, and preventing air leakage and other situations from occurring between the chassis foam and the water receiving tray;

[0029] (2) By arranging the fixing seat between the panel and the water receiving tray, there is a gap between the panel and the water receiving tray; and the Hall element is arranged in the accommodation cavity arranged on the fixing seat, and routing is carried out through the gap between the panel and the water receiving tray, which can prevent the wire from contacting the sheet metal and generating abnormal sounds, and is convenient for routing;

[0030] (3) The limit sleeve is directly arranged on the chassis foam and / or the water receiving tray, and the float switch is arranged inside the limit sleeve, thereby reducing the complexity of the structure and facilitating the installation of the float switch.

Specific embodiments

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040]

First Embodiment

[0041] [[ID=X]]Refer to Figure 1 , which is an exploded view of a water level detection device 100 provided by the first embodiment of the present invention. The water level detection device 100 includes, for example: the chassis foam 10, the water receiving tray 20, the float switch 30, the detection component 40 and the panel 60. Among them, the float switch 30 is arranged inside the chassis foam 10 and / or the water receiving tray 20; the detection component 40 is arranged on the outer side of the water receiving tray 20 away from the chassis foam , and the float switch and the detection component are arranged opposite to each other.

[0042] Specifically, refer to Figure 3 , the water level detection device 100 further includes, for example: the water collecting cavity 21. Among them, the water collecting cavity 21 is arranged on the water receiving tray 20 and the water collecting cavity 21 communicates with the float switch 30. For example, the water collecting cavity 21 is used to collect the water on the water receiving tray 20, and the water collecting cavity 21 communicates with the float switch 30, and the float switch 30 can monitor the water level in the water collecting cavity 21 in real time, so that when there is more accumulated water in the water collecting cavity 21, it can be detected through the float switch 30 in the first time, so as to make the next operation in time.

[0043] Further, the detection component 40 and the water receiving tray 20 are in mutual abutment. For example, since the existing float switch 30 and the detection component 40 are both arranged between the chassis foam 10 and the water receiving tray 20, the signal line of the detection component 40 needs to be led out from the inside of the water receiving tray 20, which may cause a risk of air leakage between the water receiving tray 20 and the chassis foam 10, and the routing of the signal line of the detection component 40 is complex, resulting in a higher cost. In the present invention, the float switch 30 is arranged inside the chassis foam 10 and / or the water receiving tray 20, the detection component 40 is arranged on the side of the water receiving tray 20 away from the chassis foam 10, and the detection component 40 and the water receiving tray 20 are in mutual abutment, so that the detection component 40 can be routed from the outside of the water receiving tray 20 and does not need to be routed from the inside of the water receiving tray 20 to the outside, thereby improving the sealing performance between the chassis foam 10 and the water receiving tray 20 and preventing air leakage and other situations between the chassis foam 10 and the water receiving tray 20.

[0044] Specifically, in combination with Figure 1 and Figure 2 , the detection component 40 includes, for example: a fixing base 41 and a Hall element 42. Among them, the fixing base 41 is provided with a receiving cavity 411, and the fixing base 41 is arranged between the panel 60 and the water receiving tray 20, so that there is a gap between the panel 60 and the water receiving tray 20; and the Hall element 42 is arranged in the receiving cavity 411.

[0045] For example, by setting a gap between the panel 60 and the water receiving tray 20 and arranging the fixing base 41 in this gap; and arranging the Hall element 42 in the receiving cavity 411 provided on the fixing base 41, and routing the wire through the gap between the panel 60 and the water receiving tray 20, it is possible to prevent the wire from contacting the sheet metal and generating abnormal noises, and it is also convenient for routing.

[0046] Preferably, an opening is provided on one side of the receiving cavity 411, and the connecting wire of the Hall element 42 can be led out from the opening, so as to facilitate routing.

[0047] Preferably, a groove is provided on the side of the water receiving tray 20 close to the fixing base 41, and the groove cooperates with the receiving cavity 411, so that the Hall element 42 can be better fixed on the side close to the water receiving tray 20, preventing the Hall element 42 from slipping out, and also improving the stability of the fixing base 41, and it is not easy to slide during movement.

[0048] Preferably, the Hall element 42 can be directly fixed to one end of the water receiving tray 20 away from the chassis foam 10, so as to save the fixing base 41.

[0049] Specifically, referring to Figure 5 , the fixing base 41 includes, for example: a plurality of limit buckles 412 and guide posts 413. Among them, the plurality of limit buckles 412 and guide posts 413 are both arranged on the side of the fixing base 41 close to the panel 60.

[0050] Further, a plurality of snap mounting positions 61 are provided on the panel 60. Among them, the plurality of snap mounting positions 61 and the limit snaps 412 are arranged in one-to-one correspondence, and the fixing base 41 is mounted on the panel 60 through the cooperation of the limit snaps 412 and the snap mounting positions 61. For example, a plurality of limit snaps 412 are provided on the fixing base 41 and a plurality of snap mounting positions 61 are provided on the panel 60. Through the cooperation of the plurality of limit snaps 412 and the plurality of snap mounting positions 61, the fixing base 41 is snapped onto the panel 60, and a gap is formed between the panel 60 and the water receiving tray 20.

[0051] Further, a guide post mounting position 62 is provided on the panel 60. Among them, the guide post 413 and the guide post mounting position 62 cooperate to enable the panel 60 to move directionally on the fixing base 41. For example, in order to prevent the panel 60 from shifting during movement, a guide post 413 is provided on the fixing base 41 and a guide post mounting position 62 is provided on the panel 60. Through the cooperation of the guide post 413 and the guide post mounting position 62, the panel 60 moves directionally on the fixing base 41.

[0052] Preferably, the plurality of limit snaps 412 are set to two, and the two limit snaps 412 are respectively installed on both sides of the fixing base 41. Correspondingly, the plurality of snap mounting positions 61 are also set to two, and the two snap mounting positions 61 are respectively arranged corresponding to the two limit snaps 412. For example, through the cooperation of the two limit snaps 412 arranged on both sides and the corresponding snap mounting positions 61, the fixing base 41 is better fixed on the panel 60.

[0053] Preferably, the fixing base 41 further includes, for example: an elastic member 43. Among them, the elastic member 43 is arranged on the guide post 413. For example, by arranging the elastic member 43 on the guide post 413, when the panel 30 moves towards the side close to the water receiving tray 20, the elastic member 43 is squeezed. When the panel 60 is not pushed, the panel 60 can be rebounded by the elastic force of the elastic member 43, so that the panel 60 automatically resets; on the other hand, the elastic member 43 can prevent the panel 60 from directly contacting the water receiving tray 20, thereby damaging the circuit provided between the panel 60 and the water receiving tray 20.

[0054] Preferably, the guide post 413 is arranged between the two limit snaps 412. Correspondingly, the guide post mounting position 62 is arranged between the two snap mounting positions 61, and the guide post 413 and the mounting position 62 are arranged oppositely. For example, by arranging the elastic member 43 on the guide post 413 arranged between the two limit snaps 412, the fixing base 41 can be evenly stressed. When the fixing base 41 is squeezed, the limit snaps 412 arranged at both ends can be evenly stressed, so that the fixing base 41 can stably descend or ascend.

[0055] Specifically, in combination with Figure 3 andFigure 4 The water level detection device 100 further includes, for example, a limit sleeve 50. The limit sleeve 50 is disposed on the chassis foam 10 and / or the water receiving tray 20. The float switch 30 is disposed within the limit sleeve 50.

[0056] For example, since the existing float switch 30 requires an installation bracket to be embedded in the chassis foam 10, resulting in a complex structure, now the limit sleeve 50 is directly disposed on the chassis foam 10 and / or the water receiving tray 20, and the float switch 30 is disposed within the limit sleeve 50, thereby reducing the complexity of the structure and facilitating the installation of the float switch 30.

[0057] Preferably, mounting holes are provided on the water receiving tray 20 and / or the chassis foam 10, and the limit sleeve 50 is disposed within the mounting holes, thereby facilitating the installation of the limit sleeve 50 on the water receiving tray 20 and / or the chassis foam 10.

[0058] Preferably, the limit sleeve 50 and the water receiving tray 20 are integrally formed, and the limit sleeve 50 can be disposed on the water receiving tray 20 when demolding, thereby reducing the steps of installing the limit sleeve 50 and improving the installation efficiency.

[0059] Preferably, at least one rib 52 is provided on the inner wall of the limit sleeve 50. For example, by providing at least one rib 52 within the limit sleeve 50, the rib 52 can reduce the movement resistance of the float switch 30, thereby ensuring that the float switch 30 does not get stuck when moving up and down, and thus improving the detection accuracy.

[0060] Preferably, the rib 52 can be provided in three, and the three ribs 52 are arranged at intervals along the vertical direction of the limit sleeve 50.

[0061] Preferably, at least one water passing hole 51 is provided on the limit sleeve 50. For example, by providing at least one water passing hole 51 on the limit sleeve 50, the interior of the limit sleeve 50 is communicated with the water receiving tray 20. Through the rise or fall of the water level on the water receiving tray 20, the rise and fall of the float switch 30 within the limit sleeve 50 are controlled, thereby judging the height of the water level within the water receiving tray 20, and thus facilitating further control.

[0062] Preferably, the at least one water passing hole 51 is three water passing holes 51, and the three water passing holes 51 are sequentially arranged at intervals on the outer wall of the limit sleeve 50.

[0063] Specifically, the float switch 30 includes, for example, a float 31 and a magnet 33. Among them, the magnet 33 is arranged inside the float 31. For example, by arranging the magnet 33 on one side of the float 31 close to the detection component 40, and the float 31 can float up and down along the inner wall of the limit sleeve 50. When the liquid level in the water receiving tray 20 is low, the magnet 33 is close to the Hall element 42, and the Hall element 42 is turned on; when the liquid level in the water receiving tray 20 is high, the magnet 33 is far from the Hall element 42, and the Hall element 42 is turned off. In this way, the height of the water level in the water receiving tray 20 is judged, so as to start or stop the water pump for drainage.

[0064] Preferably, the float switch 30 further includes, for example, an end cap 32. Among them, the end cap 32 is arranged on one side of the float 31 close to the detection component 40, and the magnet 33 is arranged inside the end cap 32. For example, since directly placing the magnet 33 inside the float 31 will cause complex processing and a high rejection rate, the processing difficulty of the float switch 30 is reduced by arranging the end cap 32 to fix the magnet 33.

[0065] Preferably, here the magnet 33 can be directly fixed inside the float 31, or directly fixed on one side of the float 31 close to the detection component 40, or the magnet 33 can be fixed on the float 31 through a fixing member. The fixing method of the magnet 33 here is not limited, as long as it is arranged on one side of the float 31 close to the detection component 40.
