Description

Technical Field

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

[0002] During the operation of the air conditioner, when the surface temperature of the air conditioner evaporator is lower than the dew point temperature of the intake air flow, water vapor will condense on the surface of the evaporator to produce condensed water. Afterwards, the condensed water falls into the water receiving tray directly or through a drainage device under the action of gravity, and is finally discharged to the outside through a drain pipe.

[0003] Among them, the floor-mounted air conditioner is an air conditioner that can be installed in both floor-mounted and ceiling-mounted installation modes. Due to the flexible installation mode of the floor-mounted air conditioner, its installation and use status is not fixed. Therefore, the floor-mounted air conditioner has higher requirements on the drainage capacity of the condensate drainage device. It is not only required to be able to guide and drain the condensate well, but also required to be able to adapt to the different installation modes of the floor-mounted air conditioner, so that the condensate can be discharged timely and completely in different installation positions of the floor-mounted air conditioner.

[0004] Through investigation, it was found that the condensate drainage device of the existing crane generally has the following defects: First, it cannot adapt to different installation methods. When the installation method of the crane changes, it may not be able to play a good drainage role or it is necessary to replace a different condensate drainage device or adjust the installation position of the condensate drainage device; Second: the structure is complex, and the drainage channel through which the condensate needs to flow is tortuous, and the condensate is difficult to discharge in time; Third: it can only collect and drain the condensate in some areas of the evaporator, and the effective area of ​​the drainage device is limited. Condensate in some areas still drips directly into the air conditioner, corroding or rusting the internal components of the air conditioner.

[0005] In order to solve the above problems, this application is proposed. Summary of the invention

[0006] The present invention designs a condensate drainage device and an air conditioner to solve the technical problems that the condensate drainage device in the existing hanging machine cannot adapt to the different installation methods of the hanging machine, has a complex structure, is difficult to quickly discharge the condensate, and the effective area of ​​the drainage device is limited, causing part of the condensate to drip directly into the air conditioner.

[0007] In order to solve the above problems, the present invention discloses a condensate drainage device, comprising:

[0008] A water receiving tray, an evaporator is arranged above the water receiving tray, and the evaporator has a first end and a second end arranged opposite to each other;

[0009] The condensate drainage device also includes:

[0010] The first water guide plate;

[0011] Cover plate;

[0012] The cover plate and the first water guide plate are relatively covered on both sides of the first end, and the first water guide plate and the cover plate can guide condensed water generated at the first end into the water receiving tray.

[0013] The condensate drainage device itself is configured with a relatively distributed first water guide plate and a cover plate at the first end of the evaporator, so that no matter whether the crane is installed in a seat type or a ceiling type, the first water guide plate and the cover plate can play a good role in guiding the condensate at the first end of the evaporator.

[0014] Furthermore, the condensate drainage device also includes: a second water guide plate, a second evaporator side plate is arranged at the second end, the second water guide plate and the second evaporator side plate cooperate to form a drainage groove at the second end, and the drainage groove can drain the condensate generated at the second end into the water receiving tray.

[0015] The condensate drainage device described in the present application can achieve the following purposes: first, the condensate from each part is treated separately, so that the condensate generated in various parts of the evaporator can be fully collected to prevent the condensate from dripping onto the internal components of the air conditioner to cause corrosion or rust; second, the first water guide plate, the second water guide plate and the cover plate have a wide range of structural options, and it is only necessary to drain the condensate from the first end and the second end of the evaporator into the water receiving tray; third, the first end and the second end of the evaporator can be protected by the first water guide plate, the second water guide plate and the cover plate at the same time to prevent the two ends of the evaporator from being damaged due to impact or long-term water accumulation.

[0016] Furthermore, the evaporator also has an air inlet surface and an air outlet surface that are arranged opposite to each other, the first water guide plate is located on the same side of the air inlet surface, and the cover plate is located on the same side of the air outlet surface.

[0017] The condensate drainage device of the present application divides the condensate generated by the evaporator into three parts for processing. The first part is the condensate on the surface of the evaporator, which is mainly the condensate on the air inlet surface and the air outlet surface. Under the guidance of the evaporator surface, it directly enters the water receiving tray; the second part is the condensate generated by the exposed heat exchange tubes at the first end of the evaporator. Under the guiding effect of the first water guide plate, it flows into the water receiving tray along the first water guide plate; the third part is the condensate generated by the exposed heat exchange tubes at the second end of the evaporator. Under the guiding effect of the second water guide plate, it flows into the water receiving tray along the second water guide plate. The condensate of each part is treated separately, which not only has a good drainage effect, but also facilitates the simplification of the structure of the drainage device. The first water guide plate is set on the same side of the air inlet surface, and the cover plate is set on the same side of the air outlet surface. The condensate can be drained by the first water guide plate and the cover plate when the condensate is installed in a seat-mounted or ceiling-mounted manner.

[0018] The first water guide plate includes a main body and a sealing plate. A corner of the main body is hollowed out to form a pipeline giving way structure. The main body is located on the same side of the air inlet surface. The sealing plate extends from the main body to the side where the air outlet surface is located and covers the end surface of the first end.

[0019] The sealing plate can cover the end parts of the first end, such as a capillary tube, to seal the end parts. On the one hand, condensed water generated at the first end is prevented from dripping into the air conditioner; on the other hand, the end parts of the first end, such as the capillary tube, are protected to prevent them from being damaged due to impact.

[0020] Furthermore, the first water guide plate also has a folded edge, and the folded edge is bent along the edge of the main plate body toward a side close to the wind outlet surface.

[0021] On the one hand, the folded edge can prevent the edge of the first water guide plate from contacting and rubbing against other components in the air conditioner, such as pipes, capillaries, etc., and cutting other components; on the other hand, it can contain and drain the condensed water collected in the first water guide plate to prevent it from spreading randomly.

[0022] Furthermore, one side of the main body extends to the water receiving tray, and an extension plate is arranged on the opposite side. The main body is arranged parallel to the air inlet surface of the evaporator, and the extension plate extends obliquely from the main body to the side close to the evaporator.

[0023] Thus, when the pedestal crane is installed in a pedestal style, the main board body and the extension board are both inclined downward from the side away from the water receiving tray to the side close to the water receiving tray, so that the condensed water collected in the first water guide plate can flow into the water receiving tray under the drainage effect of the extension board and the main board body. In addition, since the main board body and the extension board are both plate-like structures inclined downward, and there is no structure that interferes with the outflow of condensed water except for the folded edges of the edges, the condensed water generated by the heat exchange tube at the first end can flow out quickly and completely under the guidance of gravity and the first water guide plate, and the drainage effect is excellent. And because the structure of the first water guide plate is extremely simple, the manufacturing and installation process of the first water guide plate is also simplified.

[0024] Furthermore, a first evaporator side plate is installed on the first end of the evaporator, the first evaporator side plate is vertically arranged to the air inlet surface of the evaporator, and the first evaporator side plate protrudes from the air inlet surface of the evaporator, and the first evaporator side plate is connected to the first water guide plate.

[0025] The setting of the first evaporator side plate forms an L-shaped step at the connection between the air inlet surface and the first end of the evaporator. On the one hand, it provides a basis for the installation of the first water guide plate; on the other hand, a water diversion structure is formed at the end of the air inlet surface, so that the condensed water at the air inlet surface cannot spread to the first end of the evaporator and can only flow downward along the surface of the air inlet surface.

[0026] Furthermore, the first water guide plate also includes a side plate, and the connection between the side plate and the first evaporator side plate is in a step shape.

[0027] The connection between the side plate and the first evaporator side plate has a folded edge, and a step-shaped connection structure is formed at the connection between the side plate and the first evaporator side plate by overlapping the two folded edges, so that the connection between the two is stable. The first evaporator side plate can provide reliable support for the first water guide plate.

[0028] Furthermore, one side of the cover plate is connected to the sealing plate, and the other side is connected to the air outlet surface of the evaporator.

[0029] When the ceiling mounted machine is installed in a suspended ceiling style, the condensed water generated by the heat exchange tube at the first end of the evaporator through the cover plate can flow out quickly and completely under the guidance of gravity and the cover plate; in addition, the cover plate cooperates with the first water guide plate to further seal the components of the first end; at the same time, the first end, the first water guide plate and the cover plate are connected in sequence, so that the three can support each other and have high mechanical strength.

[0030] The drainage groove extends parallel to the air inlet surface, and the drainage groove can drain condensed water into the water receiving tray.

[0031] The drainage groove is provided so that no matter the pedestal machine is installed in a pedestal style or a ceiling style, the condensed water generated by the heat exchange tube at the second end of the evaporator can flow into the water receiving tray under the guidance of the drainage groove.

[0032] Furthermore, on the side where the air inlet surface is located, the second evaporator side plate protrudes from the air inlet surface.

[0033] A blocking structure is formed at the end of the air inlet surface by the second evaporator side plate, so that the condensed water on the air inlet surface can only flow downward along the air inlet surface into the water receiving tray, and cannot spread to the second end of the evaporator.

[0034] Furthermore, a top foam is provided at the connection between the evaporator and the outer shell, and the ends of the first water guide plate and the cover plate abut against the top foam.

[0035] The provision of the top foam can prevent the temperature of the evaporator from being transferred to the outer shell, thereby preventing condensation from forming on the surface of the outer shell. The sealing performance of the first water guide plate and the cover plate to the first end of the evaporator can also be further improved, so that the components on the first end, such as the capillary tube, are better sealed and airtight.

[0036] An air conditioner comprising the above-mentioned condensed water drainage device.

[0037] In summary, the condensate drainage device and air conditioner described in the present application have the following advantages: First, they can be applied to different installation methods of the crane. No matter whether the crane is mounted on the floor or on the ceiling, no changes are required. The condensate drainage device and air conditioner described in the present application can drain the condensate so that it can flow completely into the water receiving tray; Second, the condensate drainage device and air conditioner described in the present application have a simple structure, and the drainage channel is smooth and straight, which is conducive to the rapid discharge of condensate and the rapid assembly of the first water guide plate, the second water guide plate and the cover plate; Third, the condensate drainage device and air conditioner described in the present application can completely collect and guide the condensate from various parts of the evaporator, so that it can flow completely into the water receiving tray; Fourth, the condensate drainage device and air conditioner described in the present application can be realized through simple modification on the basis of the existing evaporator, and it occupies a small space and has a wide range of applications.

DETAILED DESCRIPTION

[0053] 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.

[0054] Example 1

[0055] The structure of the existing crane is generally as follows: Figures 1 to 3As shown, the existing indoor unit of the ceiling mounted air conditioner generally includes an outer shell, an air inlet and an air outlet formed on the outer shell, an evaporator and a fan arranged in the outer shell, wherein the evaporator is arranged obliquely in the outer shell, the air outlet is arranged on one side of the evaporator, the air inlet is arranged on one side of the fan, and the air outlet and the air inlet are located on the same side of the outer shell, and a water receiving pan is provided on the lower side of the evaporator, and the water receiving pan is used to collect the condensed water generated by the evaporator and discharge it in time. When the ceiling mounted air conditioner room is installed indoors by the ceiling mounted method, the ceiling mounted air conditioner is arranged in a vertical direction as a whole, the air outlet is located at the upper part of the ceiling mounted air conditioner, the evaporator is located above the fan, and the evaporator is arranged obliquely above the water receiving pan; when the ceiling mounted air conditioner room is installed indoors by the ceiling mounted method, the ceiling mounted air conditioner is installed in a horizontal direction as a whole, the air outlet and the evaporator are located at the front end of the ceiling mounted air conditioner, the fan is located at the rear end of the ceiling mounted air conditioner, and the evaporator is arranged obliquely above the water receiving pan.

[0056] During the operation of the overhead crane, the outside air first enters the overhead crane from the air inlet under the action of the fan, then passes through the evaporator from the air inlet surface of the evaporator, is discharged from the air outlet surface of the evaporator, and is finally blown out from the air outlet. When the surface temperature of the overhead crane evaporator is lower than the dew point temperature of the intake air flow, water vapor will condense on the surface of the evaporator to produce condensed water. At this time, the condensed water on the surface of the evaporator needs to be promptly and completely discharged to prevent the condensed water from spreading randomly inside the air conditioner, corroding or rusting the internal parts of the air conditioner. In this application, the side where the outside air enters the evaporator is called the air inlet surface of the evaporator, and the side where the outside air is discharged from the evaporator after completing the heat exchange with the evaporator is called the air outlet surface of the evaporator. In existing overhead cranes, the airflow generally enters the evaporator from the side of the evaporator away from the air outlet, passes through the evaporator, and enters the air outlet from the side of the evaporator close to the air outlet.

[0057] The applicant found through research that during the operation of the floor-mounted crane, the condensed water generated on the evaporator has the following characteristics: First, compared with the outlet air flow at the outlet surface of the evaporator, since the inlet air flow at the inlet surface has not yet exchanged heat with the evaporator, the temperature difference between the inlet surface and the inlet air flow is greater, and the amount of condensed water generated on the inlet surface of the evaporator is also much greater than the amount of condensed water on the outlet surface; Second, in the existing floor-mounted crane, since the evaporator is tilted above the water receiving tray, and the inlet surface and outlet surface of the evaporator have good hydrophilicity, therefore, regardless of whether the floor-mounted crane is installed in a floor-mounted or ceiling-mounted manner, the condensed water formed on the inlet surface and outlet surface of the evaporator can basically flow into the water receiving tray below under the guidance of the inlet surface and outlet surface of the evaporator; Third, in addition to the inlet surface and outlet surface of the evaporator, a large amount of condensed water will also be generated on the copper tubes exposed at both ends of the evaporator, and in the prior art, it is rare to reasonably drain, collect, and discharge this part of condensed water, which is the main reason for the condensed water to corrode or rust the internal components of the air conditioner.

[0058] In combination with the above findings, in order to solve the technical problems that the condensate drainage device in the existing overhead crane cannot adapt to the different installation methods of the overhead crane, has a complex structure, is difficult to quickly discharge the condensate, and the effective area of ​​the drainage device is limited, causing part of the condensate to drip directly into the inside of the air conditioner, the present application proposes a condensate drainage device.

[0059] Specifically, Figures 4 to 13 As shown, a condensate drainage device comprises:

[0060] A water receiving tray 2, an evaporator 1 is obliquely arranged above the water receiving tray 2, the evaporator 1 has a first end 13 and a second end 14 arranged opposite to each other, the first end 13 is connected to a pipe 6 for conveying a heat exchange medium, the first end 13 has a partially exposed heat exchange tube and other components connected to the first end 13, such as a capillary tube, etc., the pipe 6 can convey a heat exchange medium in a gaseous and / or liquid state to the inside of the evaporator 1; the second end 14 has a U-shaped heat exchange tube exposed;

[0061] The first water guide plate 3,

[0062] a cover plate 7, wherein the cover plate 7 and the first water guide plate 3 are relatively covered on both sides of the first end 13, and the first water guide plate 3 and the cover plate 7 can guide the condensed water generated at the first end 13 into the water receiving tray 2;

[0063] A second water guide plate 4, a second evaporator side plate 141 is provided at the second end 14, the second water guide plate 4 cooperates with the second evaporator side plate 141, and a drainage groove 142 is formed at the second end 14, and the drainage groove 142 can drain the condensed water generated at the second end 14 into the water receiving tray 2;

[0064] The water receiving tray 2 is provided with a drainage hole 22, and the drainage hole 22 is communicated with the outside of the seat crane.

[0065] Furthermore, the evaporator 1 also has an air inlet surface 11 and an air outlet surface 12 that are arranged opposite to each other, and the condensed water generated by the air inlet surface 11 and the air outlet surface 12 can directly flow into the water receiving tray 2 .

[0066] Furthermore, the first water guide plate 3 is located on the same side as the wind inlet surface 11 , and the cover plate 7 is located on the same side as the wind outlet surface 12 .

[0067] The condensate drainage device described in the present application divides the condensate generated by the evaporator 1 into three parts for processing. The first part is the condensate on the surface of the evaporator 1, mainly the condensate on the air inlet surface 11 and the air outlet surface 12, which directly enters the water receiving tray 2 under the guidance of the surface of the evaporator 1; the second part: the condensate generated by the exposed heat exchange tubes at the first end 13 of the evaporator 1, which flows into the water receiving tray 2 along the first water guide plate 3 or the cover plate 7 under the guiding action of the first water guide plate 3 and the cover plate 7; the third part is the condensate generated by the exposed heat exchange tubes at the second end 14 of the evaporator 1, which flows into the water receiving tray 2 along the second water guide plate 4 under the guiding action of the second water guide plate 4.

[0068] In this way, the condensate drainage device described in the present application can achieve the following purposes: first, the condensate from each part is treated separately, so that the condensate generated in various parts of the evaporator 1 can be comprehensively collected to prevent the condensate from dripping onto the internal components of the air conditioner to cause corrosion or rust; second, the first water guide plate 3, the second water guide plate 4 and the cover plate 7 have a large structural selection space, and it is only necessary to drain the condensate from the first end 13 and the second end 14 of the evaporator 1 into the water receiving tray 2; third, the first end 13 and the second end 14 of the evaporator 1 can be protected by the first water guide plate 3, the second water guide plate 4 and the cover plate 7 at the same time to prevent the two ends of the evaporator 1 from being damaged due to impact or long-term water accumulation.

[0069] Furthermore, the condensate drainage device is located in an outer shell 8, and the outer shell 8 has a shell rear wall 81. The shell rear wall 81 is arranged on both sides of the fan 9 opposite to the air inlet of the crane, and the evaporator 1 is arranged obliquely above the fan 9 and the water receiving tray 2.

[0070] Specifically, the evaporator 1 extends obliquely downward from a side close to the shell rear wall 81 to a side away from the shell rear wall 81, and forms an air inlet surface 11 of the evaporator 1 on the side close to the shell rear wall 81, and forms an air outlet surface 12 of the evaporator 1 on the side away from the shell rear wall 81. Under the action of the fan 9, the external airflow enters the evaporator 1 from the air inlet surface 11, and is blown out from the air outlet surface 12 after completing the heat exchange.

[0071] Furthermore, an air outlet is provided in a region close to the outer shell 8 and the air outlet surface 12 of the evaporator 1 , and the air outlet is arranged opposite to the shell rear wall 81 , and the airflow blown out from the air outlet surface 12 is finally discharged through the air outlet.

[0072] Furthermore, the first water guide plate 3 includes a main board body 31 and a sealing plate 32, the main board body 31 is located on the same side of the air inlet surface 11, and a corner of the main board body 31 is hollowed out, so that the main board body 31 is an "L"-shaped structure as a whole, and a yield structure 33 of the pipe 6 is formed at the hollowed-out part of the main board body 31, and the pipe 6 can extend from the first end 13 of the evaporator 1 through the yield structure 33, and the size and shape of the yield structure 33 are set according to the pipe 6; the sealing plate 32 extends from the main board body 31 to the side where the air outlet surface 12 is located, so that the sealing plate 32 can cover the end parts of the first end 13, such as capillaries, and seal the end parts. On the one hand, it prevents the condensed water generated by the first end 13 from dripping into the air conditioner; on the other hand, it protects the end parts of the first end 13, such as capillaries, to prevent them from being damaged due to impact.

[0073] Furthermore, the first water guide plate 3 also has a folded edge 34, which is bent along the edge of the main board body 31 toward the side close to the air outlet surface 12. On the one hand, it prevents the edge of the first water guide plate 3 from contacting and rubbing with other components in the air conditioner, such as the pipe 6, capillary tube, etc., and cutting other components; on the other hand, it can contain and drain the condensed water collected in the first water guide plate 3 to prevent it from spreading at will.

[0074] Furthermore, one side of the main board body 31 extends to the water receiving tray 2, and an extension plate 36 is provided on the other side. The main board body 31 is arranged parallel to the air inlet surface 11 of the evaporator 1, and the extension plate 36 extends obliquely from the main board body 31 to the side close to the evaporator 1, that is, when the seat crane is installed in a seat type, the extension plate 36 extends obliquely from the main board body 31 to the side away from the bottom surface. In this way, when the seat crane is installed in a seat type, the main board body 31 and the extension plate 36 are both inclined and extended from the side away from the water receiving tray 2 to the side close to the water receiving tray 2, so that the condensed water collected in the first water guide plate 3 can flow into the water receiving tray 2 under the drainage action of the extension plate 36 and the main board body 31.

[0075] In addition, since the main plate body 31 and the extension plate 36 are both plate-shaped structures inclined downward, and except for the folded edge 34 at the edge, there is no structure that interferes with the outflow of condensed water, so that the condensed water generated by the heat exchange tube at the first end 13 can flow out quickly and completely under the guidance of gravity and the first water guide plate 3, and the drainage effect is excellent. And because the structure of the first water guide plate 3 is very simple, the manufacturing and installation process of the first water guide plate 3 is also simplified.

[0076] Furthermore, the first water guide plate 3 further includes a side plate 35 , and the side plate 35 is vertically connected to the main body 31 . The first water guide plate 3 is connected to the first end 13 of the evaporator 1 through the side plate 35 .

[0077] Specifically, Fig. 9 As shown, a first evaporator side plate 131 is installed on the first end 13 of the evaporator 1, and the first evaporator side plate 131 is vertically arranged to the air inlet surface 11 of the evaporator 1, and the first evaporator side plate 131 protrudes from the air inlet surface 11 of the evaporator 1, and the first evaporator side plate 131 is connected to the side plate 35.

[0078] The setting of the first evaporator side plate 131 forms an L-shaped step at the connection between the air inlet surface 11 and the first end 13 of the evaporator 1, which, on the one hand, provides a basis for the installation of the first water guide plate 3; on the other hand, a water diversion structure is formed at the end of the air inlet surface 11, so that the condensed water at the air inlet surface 11 cannot spread to the first end 13 of the evaporator 1, and can only flow downward along the surface of the air inlet surface 11.

[0079] Furthermore, the cover plate 7 is located on the side where the air outlet surface 12 of the evaporator 1 is located, and a plurality of groove-shaped reinforcing strips 71 are integrally formed on the cover plate 7. Connection holes 72 are respectively arranged on both sides of the cover plate 7. One side of the cover plate 7 is connected to the sealing plate 32, and the other side is connected to the air outlet surface 12 of the evaporator 1. Firstly, when the seat crane is installed in a ceiling-mounted manner, the condensed water generated by the first end 13 can flow into the water receiving tray 2 under the drainage effect of the cover plate 7. In addition, the cover plate 7 cooperates with the first water guide plate 3 to further seal the components of the first end 13; at the same time, the first end 13, the first water guide plate 3 and the cover plate 7 are connected in sequence, so that the three can support each other and have high mechanical strength.

[0080] Further, such as Fig. 9 As shown, a second evaporator side plate 141 is provided at the second end 14 of the evaporator 1. On the side where the air inlet surface 11 is located, the second evaporator side plate 141 protrudes from the air inlet surface 11, and a blocking structure is formed at the end of the air inlet surface 11, so that the condensed water on the air inlet surface 11 can only flow downward along the air inlet surface 11 into the water receiving tray 2, and cannot spread to the second end 14 of the evaporator 1.

[0081] Furthermore, the cross section of the second evaporator side plate 141 is U-shaped, and the second evaporator side plate 141 extends parallel to the air inlet surface 11. The second water guide plate 4 includes a connecting plate 41 and a protective plate 42, and the connecting plate 41 and the protective plate 42 are vertically connected. The second water guide plate 4 is located on the same side of the air inlet surface 11, and the connecting plate 41 overlaps and is connected with the side wall portion of the second evaporator side plate 141 close to the air inlet surface 11. The connecting plate 41 is arranged parallel to the air inlet surface 11, and the protective plate 42 is located at one end of the connecting plate 41 away from the evaporator 1, and is bent from the connecting plate 41 to the side close to the flange.

[0082] A drainage groove 142 is formed at the second end 14 of the evaporator 1 through the second water guide plate 4 and the second evaporator side plate 141, and the open side of the drainage groove 142 is located on the side away from the evaporator 1, and the drainage groove 142 extends parallel to the air inlet surface 11, and one end of the drainage groove 142 is inserted into the water receiving tray 2, so that no matter the floor-mounted machine is installed in a floor-mounted or ceiling-mounted manner, the condensed water generated by the heat exchange tube at the second end 14 of the evaporator 1 can flow into the water receiving tray 2 under the guidance of the drainage groove 142.

[0083] Preferably, the open side of the drainage groove 142 is contracted to prevent the condensed water in the drainage groove 142 from flowing out from the open side of the drainage groove 142 .
