Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to a water receiving tray assembly, an evaporator assembly and an air conditioner. Background Art

[0002] In recent years, with the rapid development of the economy, people's living standards have also been improved, and air conditioners have become more and more popular. Not only household air conditioners used in daily life, but also many air conditioners for cooling mechanical equipment have gradually increased. Especially now that the number of 5G base stations is increasing, and the heat consumption of 5G base stations is very huge, the number of base station air conditioners and computer room air conditioners is also increasing. The product targeted by the present invention is a cabinet air conditioner. The circulation on the outside of this cabinet air conditioner is: outdoor - external circulation fan - condenser. There is a drainage hole under the evaporator water tray to facilitate the discharge of condensed water generated when the unit is running. However, there are two problems when this unit is running. Problem 1: Due to the presence of the drainage hole, the inside and outside are not completely isolated, resulting in the internal and external circulation intervals not meeting the dust and water requirements; when the outdoor environment is harsh, the outdoor dust will be sucked into the outside by the external fan and then enter the drainage hole, causing dust to enter the inside or block the drainage hole; Problem 2: Since the unit draws air from the bottom fan and discharges air from the condenser, when the outdoor temperature is high, the outdoor hot air will be sucked in by the outdoor fan and enter the indoor side through the drainage hole, causing the hot air to directly mix with the cold air at the evaporator, resulting in a lower outlet air temperature, thereby affecting the performance of the unit.

[0003] Since the water receiving pan of the air conditioner evaporator in the prior art has drainage holes, which makes the internal and external circulation interval unable to meet the dustproof, waterproof and hot windproof requirements and is inconvenient to install, the utility model studies and designs a water receiving pan assembly, an evaporator assembly and an air conditioner. Utility Model Content

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects in the prior art of the water receiving pan of the air conditioner evaporator having drainage holes, which makes it impossible for the internal and external circulation intervals to meet the requirements of dustproof, waterproof and hot windproof, and inconvenient installation, thereby providing a water receiving pan assembly, an evaporator assembly and an air conditioner.

[0005] In order to solve the above problems, the utility model provides a water receiving tray assembly, which includes:

[0006] A water receiving tray and a floating structure, wherein a drainage hole is provided on the water receiving tray, at least part of the structure of the floating structure is provided above the drainage hole, and at least part of the structure of the floating structure is also provided in the drainage hole. When the liquid level in the water receiving tray is greater than or equal to a preset height, the floating structure can float up and then open the drainage hole to discharge the water in the water receiving tray through the drainage hole.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0040] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values ​​set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0041] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0042] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0043] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0044] like Figure 1-11 As shown, the utility model provides a water receiving tray assembly, which includes:

[0045] A water receiving tray 1 and a floating structure 2, wherein a drainage hole 3 is provided on the water receiving tray 1, and at least part of the structure of the floating structure 2 is provided above the drainage hole 3, and at least part of the structure of the floating structure 2 is also provided in the drainage hole 3. When the liquid level in the water receiving tray 1 is greater than or equal to a preset height, the floating structure 2 can float up and then open the drainage hole 3 to drain the water in the water receiving tray 1 through the drainage hole 3. When the liquid level in the water receiving tray 1 is lower than the preset height, the floating structure 2 falls by its own gravity and closes the drainage hole 3 to prevent the upper and lower parts of the water receiving tray 1 from being connected; and at least part of the structure of the floating structure 2 located above the drainage hole 3 can be deformed so that the upper end structure of the floating structure 2 can be inserted from the bottom to the top of the drainage hole 3 from the bottom below the drainage hole 3 during the installation process.

[0046] The utility model provides a floating structure at the drainage hole of the water receiving pan, at least part of which is located above the drainage hole, and at least part of which is located in the drainage hole, so that the floating component can be floated up by the liquid in the water receiving pan to open the drainage hole, thereby discharging condensed water, and can also close the drainage hole by the gravity of the floating component itself when the liquid level drops below a preset height, thereby achieving the goal of not only discharging condensed water but also preventing air and other impurities below the water receiving pan from entering above the water receiving pan when there is less condensed water, achieving dustproof and waterproof effects, solving the problem that the internal and external circulation intervals cannot meet the dustproof and waterproof requirements, and solving the problem that the external hot air enters the evaporator through the drainage pipe, affecting the performance of the unit; and the utility model also provides a structure that can be deformed by setting at least part of the floating structure located above the drainage hole, so that it can be inserted from bottom to top above the drainage hole during installation, facilitating the installation of the floating structure and being easy to install.

[0047] The utility model utilizes the characteristics of the float. The float will move downward due to its own gravity and move upward according to the buoyancy of the condensed water (that is, it moves up and down with the liquid level, and the influence of the operation of the fan outside the water receiving pan on the gas pressure generated by the float is not considered here). When the unit is shut down or the amount of condensed water in the evaporator water receiving pan is insufficient, the float is placed statically in the drain hole. At this time, the height of the float is exactly flush with the horizontal cross-section of the drain hole; when the unit starts to run, the evaporator water receiving pan continuously produces condensed water. When the condensed water increases, the liquid level rises, and the float moves upward to open the drain hole, allowing the condensed water to be discharged from the drain hole; when the amount of condensed water is insufficient, the float falls with the liquid level to finally close the drain hole, and the cycle repeats. In this way, the problem that the internal and external circulation intervals of the cabinet air conditioner cannot be dustproof and waterproof due to the presence of the drain hole at the bottom of the middle partition can be solved, and the problem that the hot air from the outside enters the evaporator through the drain pipe, affecting the performance of the unit, can be solved.

[0048] In some embodiments,

[0049] The floating structure 2 is a floating plug, including an insertion end 4 at the upper end and a connecting rod 5 connected to the lower end of the insertion end 4. The cross-sectional area of ​​the insertion end 4 is larger than the cross-sectional area of ​​the drainage hole 3, and the cross-sectional area of ​​the drainage hole 3 is larger than the cross-sectional area of ​​the connecting rod 5. The insertion end 4 is a deformable structure and can be inserted from the bottom to the top of the drainage hole 3 during the installation process.

[0050] This is the preferred structural form of the floating structure of the utility model. The lower end of the insertion end of the utility model is connected to the connecting rod, and the cross-sectional area of ​​the connecting rod is smaller than the cross-sectional area of ​​the drainage hole, so that the connecting rod can be inserted into the drainage hole, and the cross-sectional area of ​​the insertion end is larger than the cross-sectional area of ​​the drainage hole. When the insertion end falls to contact the water receiving tray, the drainage hole can be well sealed to prevent the space above and below the water receiving tray from being connected at the drainage hole. The insertion end is set to a deformable structure, which can enable the insertion end to be inserted from the bottom of the drainage hole to the top of the drainage hole.

[0051] In some embodiments,

[0052] The shape of the longitudinal section of the floating structure 2 is an "I" shape or a "T" shape. When it is an "I" shape, the upper cross bar of the "I" shape is the insertion end 4. When it is a "T" shape, the upper cross bar of the "T" shape is the insertion end 4.

[0053] This is the preferred structural form of the floating structure of Example 1 and Example 2 of the present invention. Example 1 is an "I"-shaped structure, and Example 2 is a "T"-shaped structure. Both have a large head with a larger cross-section at the upper end, which can be effectively inserted into the upper end of the water receiving tray from bottom to top, thereby being stuck at the upper end of the drainage hole to achieve effective sealing of the upper and lower ends of the docking water tray.

[0054] In some embodiments,

[0055] The insertion end 4 is made of rubber material, and the connecting rod 5 is made of plastic material.

[0056] The insertion end of the utility model is made of rubber material and can be well deformed, and the connecting rod is made of plastic material and can produce good structural strength.

[0057] In some embodiments,

[0058] When the shape of the longitudinal cross-section of the floating structure 2 is an "I" shape, the upper cross bar of the "I" shape is made of rubber material, the middle connecting rod and the lower cross bar 6 of the "I" shape are both made of plastic material, and the cross-sectional area of ​​the lower cross bar 6 is larger than the cross-sectional area of ​​the drainage hole 3; when the shape of the longitudinal cross-section of the floating structure 2 is a "T" shape, the upper cross bar of the "T" shape is made of rubber material, and the lower vertical bar of the "T" shape is both made of plastic material.

[0059] This is the preferred structural form of the "I" shape of Example 1 and the "T" shape of Example 2 of the present invention. The upper cross bar of the "I" shape is made of rubber material and can undergo good deformation. The middle connecting rod and the lower cross bar are both made of plastic material, which can have good structural strength. The cross-sectional area of ​​the lower cross bar is larger than the cross-sectional area of ​​the drainage hole, which can limit the maximum movement height of the upper end of the floating structure through the lower cross bar when it moves upward; and the upper cross bar of the "T"-shaped floating structure is made of rubber material, which can undergo good deformation and is convenient for inserting into the upper end of the drainage hole from bottom to top. The vertical bar at the lower end is made of plastic material to have good structural strength.

[0060] Attachment Figure 4 This is a schematic diagram of the evaporator components of the present invention. The evaporator components primarily consist of the evaporator, evaporator drain pan, drain hole, and float. Below the evaporator is a drain pan with a drain hole at the bottom. An "I"-shaped float is placed in the drain hole. The float moves up and down to facilitate the drainage of condensed water.

[0061] Attachment Figure 5 This is a structural diagram of an "I"-shaped float. The float is in the shape of an "I" as a whole. The upper part of the float is made of soft rubber material, and the lower part is made of harder plastic material. The float can be inserted into the drain hole by squeezing the upper rubber part. When the upper part of the float passes through the drain hole, the rubber part returns to its original "I" shape.

[0062] Attachment Figure 6 This is a schematic diagram of the "I"-shaped float when it is stationary. When the unit is stationary or there is insufficient condensed water in the water tray, the float is forced downward as a whole due to gravity. The rubber part above the float fits against the bottom of the evaporator water tray, and the water tray and the drain hole are separated by the float. At this time, hot air, dust, wind and sand from the outside cannot enter the evaporator water tray through the drain hole and thus cannot enter the indoor side, so that the internal and external circulation intervals of the unit meet the dust and water sealing requirements.

[0063] Attachment Figure 7 This is a schematic diagram of the "I"-shaped float moving upward. When there is a lot of condensed water in the evaporator water tray, the rubber part above the float begins to be affected by buoyancy. When the buoyancy of the float is greater than the overall gravity of the float, the float is forced upward as a whole and moves upward. At this time, the water tray and the drain hole are connected, and the condensed water in the water tray can flow downward along the drain hole and eventually be discharged from the chassis of the unit.

[0064] Attachment Figure 8 This is a schematic diagram of the structure of the "T" shaped float plug. Figure 9 This is a schematic diagram of the "T" shaped float at rest. Figure 10 It is a schematic diagram of the "T"-shaped float moving upward.

[0065] If the "I" shaped float is inconvenient to operate during installation, the "I" shaped float can be replaced with a "T" shaped float. Figure 8 This is a structural diagram of the "T"-shaped float. When installing the unit, the "T"-shaped float can be directly placed from top to bottom into the drain hole of the evaporator water tray.

[0066] Attachment Figure 9 This is a schematic diagram of the "T" shaped float at rest. Figure 10 It is a schematic diagram of the upward movement of the "T" shaped float. Figure 6 , Attachment Figure 7 Keep it consistent with what is described in .

[0067] In some embodiments,

[0068] When the shape of the longitudinal cross-section of the floating structure 2 is an "I" shape, the total height of the upper cross-bar of the "I" shape plus the connecting rod 5 is greater than the total height from the upper end of the water receiving tray 1 to the lower end of the drainage hole 3; when the shape of the longitudinal cross-section of the floating structure 2 is a "T" shape, the total height of the upper cross-bar of the "T" shape plus the connecting rod 5 is greater than the total height from the upper end of the water receiving tray 1 to the lower end of the drainage hole 3.

[0069] The utility model preferably makes the total height of the upper end cross bar of the "I" shape plus the connecting rod greater than the total height from the upper end of the water receiving tray to the lower end of the drainage hole, so as to prevent the lower end cross bar of the "I" shape from abutting against the bottom end of the drainage hole during the process of the "I" shape float floating upward to reach the upper end of the water receiving tray, thereby avoiding the situation where water cannot be effectively discharged; preferably, the total height of the upper end cross bar of the "T" shape plus the connecting rod is greater than the total height from the upper end of the water receiving tray to the lower end of the drainage hole, so as to prevent the middle connecting rod of the "T" shape from completely entering the water receiving tray during the process of the "T" shape float floating upward to reach the upper end of the water receiving tray, thereby preventing the middle connecting rod of the "T" shape from falling into the drainage hole.

[0070] In some embodiments,

[0071] When the liquid level in the water receiving tray 1 is greater than or equal to a preset height, the buoyancy of the water in the water receiving tray 1 is greater than the gravity of the floating structure 2, so that the floating structure 2 can float. When the liquid level in the water receiving tray 1 is lower than the preset height, the buoyancy of the water in the water receiving tray 1 is less than the gravity of the floating structure 2, and the floating structure 2 falls by its own gravity to close the drainage hole 3.

[0072] This is the preferred structural form of the present invention, that is, through the relationship between the gravity and buoyancy of the floating structure, the condensed water in the water receiving tray can be discharged in time when drainage is needed, and when the water level is low or there is no water, the drainage hole can be closed by the gravity of the floating structure to achieve the function of liquid passage and air blocking. While achieving drainage, it can also prevent the spaces at the upper and lower ends from being connected, thereby improving the sealing and dustproof effects.

[0073] In some embodiments,

[0074] When the liquid level in the water receiving tray 1 is greater than or equal to a preset height, the floating structure 2 floats so that the lower end of the insertion end 4 is spaced apart from the bottom of the water receiving tray 1 by a preset distance greater than 0, thereby opening the drainage hole 3; when the liquid level in the water receiving tray 1 is lower than the preset height, the floating structure 2 falls down by its own gravity to the lower end of the insertion end 4 and fits into the bottom of the water receiving tray 1, thereby closing the drainage hole 3.

[0075] The present invention further preferably achieves the effect of draining or blocking water by determining whether the distance between the lower end of the insertion end and the bottom of the water receiving tray is greater than 0.

[0076] In some embodiments,

[0077] The lower end of the drainage hole 3 is also connected to a drainage pipe 7 , and the drainage pipe 7 has at least one “U”-shaped bent structure 8 , in which a water seal is provided.

[0078] The present invention further improves the sealing performance by connecting a drain pipe to the lower end of the drain hole, and the drain pipe has a "U"-shaped bend structure 8 and a water seal (preferably with the "U"-shaped opening facing upward), thereby preventing impurities at one end of the drain pipe from entering the water receiving tray through the bend section.

[0079] Attachment Figure 11 It is also a schematic diagram of the "T" shaped float moving downwards, with Figure 10 It is a schematic diagram of the upward movement of the "T" shaped float. Figure 6 , Attachment Figure 7 It remains consistent with the description in the previous article, with a newly added "U"-shaped water seal to prevent the wind from the bottom from entering the room. The floating plug can prevent wind from leaking when there is no water under the action of gravity, which has a dual effect.

[0080] The present invention further provides an evaporator assembly, which includes the aforementioned water receiving tray assembly and an evaporator 9. The evaporator 9 is located above the water receiving tray assembly.

[0081] Attachment Figure 1 This is a schematic diagram of the evaporation side of the unit water tray, attached Figure 2 This is a schematic diagram of the condensing side of the unit’s water tray. Figure 3This is a side view of the unit's water collection pan. The condensed water generated on the unit's evaporator first drips from the evaporator to the evaporator's water collection pan, then drips from the drainage holes on the water collection pan to the unit's chassis, and finally is discharged from the gap in the chassis.

[0082] The utility model also provides an air conditioner, which includes the above-mentioned evaporator assembly.

[0083] The utility model designs a cabinet air conditioner with a new drainage structure. An "I"-shaped float plug is added to the drainage hole of the evaporator water receiving pan. The buoyancy and gravity of condensed water and the characteristics of the piston are utilized to solve the following two problems.

[0084] 1. Solve the problem that the internal and external circulation intervals cannot meet the upper and lower sealing performance requirements of the water receiving pan due to the presence of drainage holes in the evaporator water receiving pan of the unit;

[0085] 2. Solve the problem that the hot air from outside enters the evaporator through the drain pipe, affecting the performance of the unit.

[0086] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention. The above description is only a preferred embodiment of the present invention.
