Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioning water receiving structure and an air conditioner. Background Art

[0002] With the development and progress of society, users have higher and higher requirements for air conditioning performance. After using for a long time, the water drops from the evaporator fall into the water tray and are discharged outdoors. After the water drops flow through the water tray, a lot of dust will remain, which is easy to breed bacteria; these microorganisms are easy to enter the room with the airflow after heat exchange, affecting the air quality and causing health problems for users, such as "air conditioning disease".

[0003] The water tray of the existing cabinet is usually fixed to the evaporator and the rear tail plate by buckles and screws, and cannot be disassembled and cleaned separately. The user needs to disassemble the evaporator assembly before cleaning. The cleaning steps are complicated and the disassembly and cleaning are difficult. The Chinese patent with application number 201721611118.3 discloses an air conditioning cabinet, including a shell, a heat exchanger and an upper water tray, which is slidably installed in the shell. The upper water tray is located below the heat exchanger, and the bottom surface of the upper water tray is provided with a drain port; the lower water tray is located below the drain port, and the bottom surface of the lower water tray is provided with a connecting port. This solution does not require the entire shell to be disassembled, which is convenient for cleaning the water tray; but when cleaning, the upper water tray is easy to fall off from the air conditioner, and it is difficult for ordinary users to assemble it; in addition, since the upper water tray can be pulled out, it is impossible to effectively collect the condensed water on the evaporator connecting pipe, and this part of the condensed water is also easy to breed bacteria in the air conditioner. Summary of the invention

[0004] The problem solved by the present invention is how to facilitate the removal of the water receiving pan and fully discharge the condensed water generated by the evaporator.

[0005] In order to solve the above problems, the present invention provides an air-conditioning water collection structure, which is arranged below the evaporator, and the air-conditioning water collection structure includes a first pull-out water collection tray; it also includes a second water collection tray located above the first water collection tray, and the second water collection tray is provided with a second drain outlet, and the second drain outlet extends downward to stop and limit the pulling out of the first water collection tray.

[0006] The second water tray can collect dripping water from the copper tube connected to the evaporator, and flow into the first water tray through the second drain port, so as to fully collect the condensed water produced by the evaporator; at the same time, the second drain port can limit the withdrawal process of the first water tray to prevent the first water tray from being completely removed from the air conditioner, making it convenient for ordinary users to clean the water tray after opening the front panel assembly.

[0007] Preferably, the first water receiving tray is provided with a flange on a side close to the evaporator, and an upper end surface of the flange is higher than a lower end surface of the second drain outlet.

[0008] When the first water receiving tray is pulled out, the second drain port abuts against the flange, thereby limiting the movement of the first water receiving tray. This arrangement has a simple structure and prevents the first water receiving tray from completely falling out.

[0009] Preferably, the air conditioner water receiving structure further comprises slide grooves arranged on both sides of the first water receiving tray, and the first water receiving tray is slidably connected to the slide grooves. This arrangement can guide and limit the pulling of the first water receiving tray, and the first water receiving tray slides along the slide grooves to prevent the first water receiving tray from deflecting.

[0010] Preferably, the slide groove includes a connected supporting portion and a limiting portion, the supporting portion abuts against the lower end surface of the first water receiving tray, and the limiting portion abuts against the outer wall of the flange; this arrangement can solve the problem that the water receiving tray and the evaporator assembly need to be disassembled and the water receiving structure is difficult to disassemble and clean.

[0011] Preferably, a decorative plate is provided on the side of the first water receiving tray close to the evaporator, and the decorative plate is connected to the flange and is arranged higher than the flange. This arrangement can shield the second water receiving tray and / or the lower bracket, thereby improving the aesthetics of the air conditioner; on the other hand, the decorative plate can be grasped when pulling out, which is convenient for applying force. The decorative plate is arc-shaped and arranged along the circumference of the first water receiving tray.

[0012] Preferably, a first connecting pipe extending downward is provided at the lower end of the evaporator, and the first connecting pipe is provided through the second water receiving tray.

[0013] This setting can use the second water receiving tray to collect the condensed water generated by the first connecting pipe and the second connecting pipe and gather it into the first water receiving tray, so as to prevent the condensed water from flowing down to the base and affecting the operating reliability of the air conditioner, avoid bacterial growth, and ensure the quality of air entering the room.

[0014] Preferably, the second water receiving tray is provided with a first accommodating portion, and the first accommodating portion is attached to the outer periphery of the first connecting pipe; a second connecting pipe is also provided at the lower end of the evaporator, and a second accommodating portion is also provided at the corresponding position of the second water receiving tray, and the second accommodating portion is attached to the outer periphery of the second connecting pipe.

[0015] This arrangement uses a connecting pipe to fix the second water receiving tray, which can increase the contact area between the two and make the assembly tighter; at the same time, it prevents condensed water from the second water receiving tray from flowing downward along the gap, and the water collection effect is good.

[0016] Preferably, the air conditioner water receiving structure also includes a lower bracket for supporting the evaporator, the lower bracket includes a connected main body and a first reinforcing plate, one end of the first reinforcing plate is provided with a water guide groove, and one end of the water guide groove is provided with a water trough hole for draining condensed water to the middle area of ​​the first water receiving tray.

[0017] The middle area refers to a larger area near the center of the first water receiving tray. This arrangement can shorten the flow distance of the condensed water from both ends of the guide portion, avoid the condensed water from gathering and overflowing due to the long flow distance, and make the condensed water drip to the middle position of the first water receiving tray to avoid splashing. Preferably, the main board body is arranged symmetrically along the first reinforcing plate. This arrangement has a simple structure and a beautiful appearance.

[0018] Preferably, the main board body is "U-shaped", and the lower bracket also includes a second reinforcing plate, which is respectively connected to both ends of the main board body; the first reinforcing plate is arranged between the main board body and the second reinforcing plate.

[0019] The structure of the arrangement is simple, and can improve the mechanical strength of the lower bracket, and improve the safety and reliability of the air conditioner operation. Preferably, an electric heating structure is arranged on the second reinforcing plate.

[0020] Preferably, the main board body comprises a supporting portion and a guide portion, the supporting portion abuts against the lower end portion of the evaporator, and the periphery of the supporting portion is recessed downward to form the guide portion.

[0021] This arrangement allows the condensed water generated by the evaporator to flow to the support portion, then quickly enter the guide portion nearby and finally flow to the first water receiving tray. The evaporator will never be submerged in the condensed water, and the heat exchange efficiency is high and the cooling effect is good.

[0022] Compared with the prior art, the air conditioning water receiving structure described in the present invention has the following beneficial effects: (1) The air conditioning water receiving structure described in the present application uses the second water receiving tray to limit the withdrawal of the first water receiving tray, thereby preventing the first water receiving tray from completely falling out during cleaning; at the same time, the second water receiving tray can collect dripping water from the connecting pipe, preventing a small amount of condensed water from flowing downward, thereby preventing the growth of bacteria and affecting the air quality; (2) By providing a slide groove, the first water receiving tray can be slid out to avoid being separated from the evaporator assembly, and the operation is simple; (3) By providing a lower bracket, the evaporator is supported, and at the same time, the condensed water is allowed to drip into the middle area of ​​the first water receiving tray to avoid splashing and overflowing around, and the water collection effect is good.

[0023] The present invention also provides an air conditioner, comprising the air conditioner water connection structure. The air conditioner has the same beneficial effects as the air conditioner water connection structure, which will not be described in detail here.

[0024] Preferably, the air conditioner further comprises a front panel assembly, the front panel assembly comprises a lining plate, and a sliding door assembly covering the outer side of the lining plate, and a clearance hole is arranged on the lining plate at a position relative to the first water receiving tray.

[0025] Since the lining plate is covered by the sliding door assembly, the hole is hidden inside, so the appearance of the product can be avoided. This arrangement can achieve the push and pull of the first water receiving tray by only opening the sliding door assembly without removing the entire shell, thereby greatly facilitating the cleaning of the upper water receiving tray, reducing the removal of parts, and greatly facilitating the extraction of the first water receiving tray.

DETAILED DESCRIPTION

[0036] 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.

[0037] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0038] In addition, in the present invention, the descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0039] As the air conditioner runs longer and the water is not completely drained, the dust in the water tray will form damp sludge, which is a breeding ground for bacteria. These bacteria will enter the room with the air flow, affecting the air quality and causing health problems for users, such as "air conditioning disease".

[0040] In the existing air conditioner structure, the water receiving structure is usually located at the bottom of the air conditioner or fixedly connected to other structures, and cannot be disassembled and cleaned separately, which makes cleaning difficult; if the water receiving tray is movably connected, the water droplets condensed on it cannot be effectively collected and discharged because the connecting pipe needs to extend downward; at the same time, the water receiving tray is very easy to completely fall out when pulled out, and reassembly is cumbersome. The applicant proposes the following solution:

[0041] like Figure 1-3 As shown, an air conditioning cabinet includes a shell, in which an evaporator 6 and a water receiving structure 1 are arranged, and the water receiving structure 1 includes a first water receiving tray 12 and a second water receiving tray 13. The first water receiving tray 12 is located below the evaporator 6 and is movably installed in the shell, and a first drain port 124 is provided on its bottom surface for discharging the collected condensed water; a second drain port 131 is provided on the bottom surface of the second water receiving tray 13 for discharging the condensed water on the connecting pipe to the first water receiving tray 12 located below, and at the same time, the extraction process of the first water receiving tray 12 is limited. As another example of the present invention, the water receiving structure 1 also includes a lower bracket 11 installed at the lower end of the evaporator 6, and a connected water guide groove 1121 and a water trough hole 1122 are provided on the lower bracket 11, which are used to guide the condensed water generated by the evaporator 6 to the first water receiving tray 12 in an orderly manner.

[0042] The housing includes a front panel assembly 3 and a back panel arranged opposite to the front panel assembly 3. The front panel assembly 3 includes a lining plate 32 and a sliding door assembly 31 covering the outside of the lining plate 32. The sliding door assembly 31 is movably mounted on the lining plate 32 or the back panel. A clearance hole 321 is arranged on the lining plate 32. The clearance hole 321 can be exposed through the rotation connection or sliding connection of the sliding door assembly 31. As an example of the present invention, one side edge of the sliding door assembly 31 is rotationally connected to the lining plate 32. Preferably, a plurality of rollers 311 are arranged on the lining plate 32. The sliding door assembly 31 slides to one side through the rollers 311, thereby leaking the air outlet and / or the clearance hole 321.

[0043] The shell also includes a base 4 and a top cover 5. The lower ends of the front panel assembly 3 and the back panel are mounted on the base 4, and the top cover 5 covers the upper ends of the front panel assembly 3 and the back panel. Preferably, the back panel is provided with an air inlet facing the evaporator 6, the front panel assembly 3 is provided with an air outlet, and the shell has an air duct assembly 2 connecting the air inlet and the air outlet. The air duct assembly 2 is a prior art and will not be described in detail here. When working, the airflow outside the shell enters the air duct assembly 2 from the air inlet, forms a supply airflow after heat exchange in the evaporator 6, and blows into the room from the air outlet. Preferably, the air conditioner is generally square or cylindrical, the front panel assembly 3 and the back panel are both arc-shaped plates, and the front panel assembly 3 and the back panel are connected to each other to enclose a closed ring structure.

[0044] like Figure 5 As shown, the lower bracket 11 includes a main board body 111 in a "U" shape, and the main board body 111 includes a support portion 1111 and a guide portion 1115. The support portion 1111 is in contact with the lower end of the evaporator 6, and the outer periphery of the support portion 1111 is recessed downward to form the guide portion 1115. This arrangement allows the condensed water generated by the evaporator 6 to flow to the support portion 1111, and then quickly enter the guide portion 1115 nearby and finally flow into the first water receiving tray 12. The evaporator 6 will never be submerged in the condensed water, and the heat exchange efficiency is high and the cooling effect is good. A second folded edge 1113 is provided on the inner peripheral side of the support portion 1111, and the second folded edge 1113 extends upward to limit the installation position of the evaporator 6 and prevent the condensed water from flowing freely. A first folded edge 1112 is provided on the outer peripheral side of the guide portion 1115, and the second folded edge 1113 extends upward, which can further improve the mechanical strength of the lower bracket 11; preferably, a plurality of buckles 1114 are provided on the upper end of the first folded edge 1112 for assembling and fixing the lower bracket 11 to the rear tail plate, etc.

[0045] Preferably, the lower bracket 11 further includes a first reinforcing plate 112 and a second reinforcing plate 113, wherein the second reinforcing plate 113 is connected to both ends of the main body 111 respectively; one end of the first reinforcing plate 112 is connected to the main body 111, and the other end is connected to the second reinforcing plate 113. Preferably, the first reinforcing plate 112 is provided with a water guide groove 1121, one end of which is connected to the flow guide portion 1115, and a water trough hole 1122 is provided at one end of the water guide groove 1121 close to the second reinforcing plate 113. Condensed water is collected along the flow guide portion 1115 to the water guide groove 1121, and finally drips into the first water receiving tray 12 through the water trough hole 1122. This arrangement can shorten the flow distance of the condensed water from both ends of the flow guide portion 1115, avoid the condensed water from being collected and overflowing due to the long flow distance, and make the condensed water drip to the middle position of the first water receiving tray 12 to avoid splashing and dispersion. Preferably, an electric heating fixing structure 114 is provided on the second reinforcing plate 113 . The electric heating fixing structure 114 is a prior art and will not be described in detail herein.

[0046] like Figure 6 As shown, the first water receiving tray 12 includes a bottom plate 121, and a first drain port 124 is arranged on the bottom plate 121. The lower part of the first drain port 124 is connected to a drain pipe (not shown in the figure) for draining condensed water. The first water receiving tray 12 also includes a decorative plate 123 and a flange 122. The decorative plate 123 and the flange 122 are surrounded by the peripheral side of the bottom plate 121; preferably, the decorative plate 123 is arranged higher than the flange 122. During assembly, the decorative plate 123 cooperates with the clearance hole 321 to form a shield for the second water receiving tray 13 and / or the lower bracket 11, thereby improving the aesthetics of the air conditioner; on the other hand, the decorative plate 123 can be grasped when pulling to facilitate force application.

[0047] Preferably, the flange 122 includes a first flange 1221 and a second flange 1222, the first flange 1221 is arranged at one end away from the decorative plate 123, one end of the second flange 1222 is connected to the decorative plate 123, and the other end of the second flange 1222 is connected to the first flange 1221. Preferably, the first flange 1221 and the second flange 1222 are integrally formed, which is convenient for production and processing and improves the mechanical strength of the product. As an example of the present invention, the water receiving structure 1 also includes a slide groove 14, and the slide groove 14 is arranged on both sides of the first water receiving tray 12, and the first water receiving tray 12 can be slidably pushed in or pulled out along the slide groove 14. The slide groove 14 and the lining plate 32 are integrally formed or separately arranged, such as snap-fitted or screwed. Figure 8As shown, the slide 14 includes a connected sliding portion 141 and a limiting portion 142, wherein the sliding portion 141 abuts against the lower end surface of the bottom plate 121, and the limiting portion 142 abuts against the outer side wall of the second flange 1222. This arrangement is configured such that the first water receiving tray 12 cooperates with the slide 14, and when the sliding door assembly 31 is opened, the first water receiving tray 12 can be directly pulled out for cleaning, thereby achieving an effect of an easy-to-disassemble and wash water receiving structure, thereby solving the problem that the water receiving tray and the evaporation structure need to be separated and the water receiving structure is difficult to disassemble and wash. As another example of the present invention, a convex rib is provided on the outer side of the first flange 1221, and the convex rib extends from the outside to the inside, and the first water receiving tray 12 is slidably installed in the slide 14 through the convex rib. This arrangement can reduce the contact area between the two and reduce friction.

[0048] like Figure 8 As shown, the second water receiving tray 13 is provided with a first accommodating portion 132 and a second accommodating portion 133, which are respectively used to install the first connecting pipe 61 and the second connecting pipe 62 of the evaporator 6, that is to say: the first accommodating portion 132 is attached to the outer periphery of the first connecting pipe 61, and the second accommodating portion 133 is attached to the outer periphery of the second connecting pipe 62; the second drain outlet 131 is provided at the lower end of the second water receiving tray 13, and the lower end surface of the second drain outlet 131 is lower than the upper end surface of the first flange 1221, so as to limit the pulling and drawing of the first water receiving tray 12.

[0049] During operation, the condensed water generated by the evaporator 6 flows down to the support portion 1111, enters the water guide groove 1121 along the guide portion 1115, and drips to the first water receiving pan 12 through the water groove hole 1122; at the same time, the condensed water condensed on the first connecting pipe 61 and the second connecting pipe 62 of the evaporator 6 enters the second water receiving pan 13, and drips to the first water receiving pan 12 through the second drain port 131; the condensed water in the first water receiving pan 12 is discharged through the drain pipe connected to the first drain port 124. When cleaning, first open the sliding door assembly 31, apply force outward to slide the first water receiving pan 12 out of the clearance hole 321; when the first flange 1221 abuts against the second drain port 131, the second drain port 131 interferes with and limits the first water receiving pan 12, preventing the first water receiving pan 12 from completely falling out; after washing with water or wiping with a rag, push the first water receiving pan 12 back to its original position again, and close the sliding door assembly 31. The air conditioner housing does not need to be opened during the whole process, and the condensed water is completely collected. Meanwhile, the first water receiving tray 12 will not be completely separated from the air conditioner, which is convenient for users to clean it by themselves.

[0050] The present invention also proposes an air conditioner, which is a cabinet-type air conditioner. In addition to the air conditioning water connection structure and related assembly structures, the air conditioner also includes air conditioning components such as cross-flow blades, motors, wind sweeping structures, and electronic control structures. In view of the fact that the specific structures and specific assembly relationships of the related components are all prior art, they are not elaborated here.

[0051] It should be noted that the directional terms mentioned in the embodiments of the present invention are all based on the conditions of the air conditioner under normal assembly and normal installation and placement, where "up" refers to the upper direction or space of the air conditioner under normal assembly and normal installation and placement, "down" refers to the lower direction or space of the air conditioner under normal assembly and normal installation and placement, "horizontal" refers to the horizontal plane direction of the air conditioner under normal assembly and normal installation and placement, and the terms "left", "right", "front" and "back" are the same and will not be elaborated here; the same as the conventional understanding, the "horizontal" direction is perpendicular to the "up and down" direction or the "vertical" direction.

[0052] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
