Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to a rooftop unit. Background Art

[0002] Air conditioning, or air conditioner, refers to a device that uses artificial means to adjust and control the temperature, humidity, flow rate and other parameters of the ambient air in a building or structure.

[0003] A rooftop unit is a type of air conditioner, which includes a body. The interior of the body is divided into an indoor side and an outdoor side by a partition. The indoor side is provided with an indoor heat exchanger and an indoor fan, and the outdoor side is provided with an outdoor heat exchanger, a compressor and an outdoor fan. An air outlet is provided on the body, and the air is exchanged through the indoor heat exchanger and the outdoor heat exchanger to achieve air cooling or heating. The indoor fan blows the heat-exchanged air through the air outlet to the room to adjust the indoor temperature.

[0004] Because the rooftop unit is installed outdoors, when it rains, rainwater will enter the outdoor side, and the accumulated water on the outdoor side will enter the indoor side and then enter the room, affecting the user's use. In the prior art, the waterproof solution is to separate the indoor and outdoor sides with partitions, and then apply glue at the bottom of the partition to prevent water from the outdoor side from entering the indoor side. When the factory assembles the product and applies glue to seal, the uniformity of the glue cannot be guaranteed, and it is easy to miss points. At the same time, the waterproof glue will age and fail after long-term use. After the waterproof glue fails, water will flow into the indoor side from the failed waterproof glue position, so the glue solution is unreliable from the perspective of production and subsequent use. Utility Model Content

[0005] The utility model solves one of the technical problems in the related art at least to a certain extent.

[0006] To this end, the present application aims to provide a rooftop unit, which realizes a close fitting connection between the partition and the indoor bottom plate through the first flange and the second flange, so as to prevent the outdoor water from flowing into the indoor side through the gap between the indoor bottom plate and the partition. Even if some of the water will enter between the partition and the indoor bottom plate, the water level on the outdoor side must be higher than the first flange and the second flange to flow into the indoor side, which is more difficult, and further prevents the outdoor water from flowing into the indoor side; thereby preventing the water from entering the room and affecting the user, and improving the user experience.

[0007] In order to achieve the above object, the utility model provides a rooftop machine, comprising:

[0008] substrate;

[0009] A housing, which is opened on one side facing the substrate, is disposed on the substrate, and the substrate closes the housing;

[0010] A partition plate is disposed in the casing, and is used to separate the interior of the casing into an indoor side and an outdoor side;

[0011] An indoor heat exchanger, which is arranged on the indoor side;

[0012] An outdoor heat exchanger is arranged on the outdoor side, the indoor heat exchanger and the outdoor heat exchanger are connected by a pipeline, and a refrigerant flows between the indoor heat exchanger and the outdoor heat exchanger to achieve heat exchange of the airflow passing through the indoor heat exchanger and the outdoor heat exchanger;

[0014] An outdoor bottom plate is arranged on the outdoor side and attached to the base plate; a side of the outdoor bottom plate close to the partition plate is bent in a direction away from the base plate to form a second flange;

[0015] The first flange is attached to the outdoor bottom plate at a side facing the base plate; and the second flange is attached to the partition at a side facing the indoor side.

[0016] In the technical solution, the partition and the indoor bottom plate are tightly connected by the first flange and the second flange to prevent the outdoor water from flowing into the indoor side through the gap between the indoor bottom plate and the partition. Even if some of the water enters between the partition and the indoor bottom plate, the water level on the outdoor side must be higher than the first flange and the second flange to flow into the indoor side, which is difficult, and further prevents the outdoor water from flowing into the indoor side; thereby preventing the water from entering the room and affecting the users, and improving the user experience.

[0017] In addition, the present application also provides a rooftop unit, which includes:

[0018] substrate;

[0025] Wherein, the first flange is clamped between the outdoor bottom plate and the base plate; and the second flange is attached to a side of the partition plate facing the outdoor side.

[0026] In the technical solution, the partition and the indoor bottom plate are tightly connected by the first flange and the second flange to prevent the outdoor water from flowing into the indoor side through the gap between the indoor bottom plate and the partition. Even if some of the water enters between the partition and the indoor bottom plate, the water level on the outdoor side must be higher than the first flange and the second flange to flow into the indoor side, which is difficult, and further prevents the outdoor water from flowing into the indoor side; thereby preventing the water from entering the room and affecting the users, and improving the user experience.

[0034] In the technical solution, the indoor side is separated from the substrate by a second thermal insulation layer, thereby improving the thermal insulation effect between the indoor side and the indoor room and reducing the impact on the air temperature of the indoor side after heat exchange by the indoor heat exchanger.

[0035] In some embodiments of the present application, the substrate, the second thermal insulation layer and the indoor bottom plate are respectively penetrated by and correspond to a first air outlet, a second air outlet and a third air outlet.

[0036] In the technical solution, the airflow after heat exchange in the indoor heat exchanger passes through the third air outlet, the second air outlet and the first air outlet in sequence and is output to the indoor room.

[0037] In some embodiments of the present application, an edge of the substrate close to the first air outlet is bent toward one side of the indoor bottom plate to form a fourth flange.

[0062] In the present application, the rooftop unit includes an indoor side and an outdoor side, and an indoor heat exchanger and an indoor fan are arranged on the indoor side. An outdoor heat exchanger and an outdoor fan are arranged on the outdoor side, and the refrigerant flowing between the indoor heat exchanger and the outdoor heat exchanger is used to realize heat exchange between the indoor heat exchanger and the outdoor heat exchanger. The heat exchange fan is used to blow the airflow after heat exchange through the indoor heat exchanger into the room to realize the adjustment of the indoor temperature.

[0063] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0064] As attached Figures 1 to 12 As shown, in an illustrative embodiment of the rooftop machine of the utility model, the rooftop machine includes: a base plate 100, a casing 200, a partition 700, an indoor heat exchanger 300, an outdoor heat exchanger 400 and an outdoor bottom plate 800; the casing 200 is opened on one side facing the base plate 100.

[0065] The housing 200 is disposed on the substrate 100 .

[0066] The base plate 100 encloses the housing 200 .

[0067] The partition plate 700 is disposed in the casing 200 , and is used to separate the interior of the casing 200 into an indoor side and an outdoor side.

[0068] The indoor heat exchanger 300 is provided on the indoor side.

[0069] The outdoor heat exchanger 400 is arranged on the outdoor side, the indoor heat exchanger 300 and the outdoor heat exchanger 400 are connected by a pipeline, and a refrigerant flows between the indoor heat exchanger 300 and the outdoor heat exchanger 400 to achieve heat exchange for the air flow passing through the indoor heat exchanger 300 and the outdoor heat exchanger 400.

[0070] A side of the partition plate 700 close to the base plate 100 is bent toward the outdoor side to form a first flange 701 .

[0071] The outdoor bottom plate 800 is disposed on the outdoor side and attached to the base plate 100 .

[0072] The side of the outdoor bottom plate 800 close to the partition 700 is bent away from the base plate 100 to form a second flange 801; wherein the first flange 701 is attached to the outdoor bottom plate 800 on the side facing the base plate 100; the second flange 801 is attached to the side of the partition 700 facing the indoor side.

[0073] Through the above solution, the partition 700 is tightly connected to the indoor bottom plate 900 through the first flange 701 and the second flange 801 to prevent the outdoor water from flowing to the indoor side through the gap between the indoor bottom plate 900 and the partition 700.

[0074] Moreover, even if some of the accumulated water enters between the partition 700 and the indoor bottom plate 900, the water level on the outdoor side must be higher than the first flange 701 and the second flange 801 to flow into the indoor side, which is more difficult, further preventing the accumulated water on the outdoor side from flowing into the indoor side; thereby preventing the accumulated water from entering the room and affecting the users, thereby improving the user experience.

[0075] In the prior art, the partition 700 is directly disposed on the substrate 100, and the two sides of the substrate 100 are respectively the indoor side and the outdoor side. The partition 700 and the substrate 100 are sealed with glue to prevent water from the outdoor side from entering the indoor side.

[0076] However, when the factory assembles the product and applies glue to seal it, it is impossible to ensure the uniformity of the glue application, and it is easy to miss some spots. At the same time, the waterproof glue will age and become ineffective after long-term use. After the waterproof glue fails, water will flow into the interior from the location of the failed waterproof glue. Therefore, the glue application plan is unreliable from the perspective of production and subsequent use.

[0077] In some embodiments, the angle between the first flange 701 and the partition 700 is the same as the angle between the second flange 801 and the outdoor bottom plate 800. After installation, the first flange 701 can be completely attached to the outdoor bottom plate 800, and the second flange 801 can be completely attached to the partition 700, thereby improving the tightness of the connection between the two.

[0078] In some embodiments, the partition 700 is perpendicular to the substrate 100 , and the first flange 701 is perpendicular to the partition 700 .

[0079] The outdoor bottom plate 800 is parallel to the base plate 100 , and the second side is perpendicular to the outdoor bottom plate 800 .

[0080] The outdoor bottom plate 800 is attached to the upper surface of the base plate 100 .

[0081] The first flange 701 is parallel to and in contact with the upper surface of the outdoor base plate 800 .

[0082] The second flange 801 is parallel to and attached to a side of the partition plate 700 facing the indoor side.

[0083] In some embodiments, in order to further improve the sealing between the partition 700 and the outdoor bottom plate 800, a sealant may be provided between the first flange 701 and the outdoor bottom plate 800.

[0084] First, sealant is applied, and then the outdoor bottom plate 800 is connected to the partition 700. The partition 700 and the bottom plate are brought close to each other to compress the sealant so that the sealant can completely fill the gap between the first flange 701 and the outdoor bottom plate 800, thereby avoiding the occurrence of leaks.

[0085] In some embodiments, a sealant is disposed between the second flange 801 and the partition 700 .

[0086] First, sealant is applied, and then the outdoor bottom plate 800 is connected to the partition 700. The partition 700 and the bottom plate are brought close to each other to compress the sealant so that the sealant can completely fill the gap between the second flange 801 and the partition 700, thereby avoiding the occurrence of leakage points.

[0087] In some embodiments, a first drainage hole 150 is formed through the substrate 100 .

[0088] In some embodiments, a second drainage hole 150 is formed through the outdoor bottom plate 800 .

[0089] The first drain hole 150 is connected to the second drain hole 150 to form the drain hole 150 , and the accumulated water entering the outdoor side can be discharged through the drain hole 150 .

[0090] In some embodiments, a plurality of drainage holes 150 are provided, and the plurality of drainage holes 150 can enhance the drainage effect.

[0091] In some embodiments, the dimension of the second flange 801 away from the outdoor base plate 800 is greater than 25 mm.

[0092] In some embodiments, the width of the second flange 801 is greater than 25 mm. The second flange 801 is relatively large because the accumulated water on the outdoor side needs to exceed the height of the second flange 801 to flow into the indoor side. However, due to the drainage hole 150, in actual use, the accumulated water on the outdoor side is almost impossible to exceed the second flange 801, so it is difficult for the accumulated water on the outdoor side to enter the indoor side and flow into the room.

[0093] In some embodiments, a dimension of the first flange 701 in a direction away from the partition 700 is greater than 15 mm.

[0094] In some embodiments, the width of the first flange 701 is greater than 15 mm, so as to ensure the contact area between the first flange 701 and the outdoor bottom plate 800, improve the connection strength between the partition 700 and the outdoor bottom plate 800, and prevent the partition 700 from tilting and falling.

[0095] In some embodiments, the drainage hole 150 is close to the second flange 801 .

[0096] A plurality of drainage holes 150 are arranged at intervals along the length direction of the second flange 801 to increase the discharge amount of accumulated water near the partition 700 on the outdoor side, thereby improving the drainage effect of accumulated water near the second flange 801 and further preventing the accumulated water at the second flange 801 from being higher than the second flange 801 and flowing into the indoor side.

[0097] In some embodiments, an indoor bottom plate 900 is disposed in the housing 200 , and the indoor bottom plate 900 is disposed on the indoor side.

[0098] The indoor bottom plate 900 is spaced apart from the base plate 100 .

[0099] The indoor heat exchanger 300 is arranged on the side of the indoor bottom plate 900 away from the base plate 100. Even if some accumulated water flows into the indoor side through the outdoor side, the accumulated water is located on the base plate 100, away from the indoor heat exchanger 300 on the indoor bottom plate 900, avoiding damage to the indoor heat exchanger 300.

[0100] In some embodiments, the edge of the indoor bottom plate 900 is bent toward one side of the base plate 100 to form a third flange 901 , and the third flange 901 is pressed against the base plate 100 .

[0101] The third flange 901 is used to realize the spacing between the indoor bottom plate 900 and the base plate 100. In addition, the accumulated water entering the indoor side is blocked by the third flange 901, further preventing the water flow from entering the indoor side through the indoor side.

[0102] In some embodiments, the indoor bottom plate 900 is parallel to the base plate 100 , and the third flange 901 is perpendicular to the indoor bottom plate 900 .

[0103] In some embodiments, the third flange 901 extends toward the substrate 100 .

[0104] In some embodiments, the distance of the third flange 901 away from the indoor bottom plate 900 is the width of the third flange 901 , and the spacing between the substrate 100 and the indoor bottom plate 900 may be different from the width of the third flange 901 .

[0105] A support member may be provided between the indoor bottom plate 900 and the base plate 100 for supporting the indoor bottom plate 900 on the base plate 100 .

[0106] In some embodiments, a first thermal insulation layer 130 is attached to the side of the partition 700 facing the indoor side.

[0107] In some embodiments, the side of the first insulation layer 130 close to the substrate 100 is located between the indoor bottom plate 900 and the substrate 100. The first insulation layer 130 improves the heat insulation effect to reduce the mutual influence of the indoor and outdoor temperatures and improve the heat exchange effect.

[0108] In some embodiments, a support bar is disposed on one side of the first temperature insulation layer 130 close to the substrate 100 . The support bar is located between the partition plate 700 and the corresponding third flange 901 . The support bar is used to support the first temperature insulation layer 130 .

[0109] In some embodiments, the support bar is attached to a side of the second flange 801 away from the partition 700 .

[0110] In some embodiments, the material of the first temperature insulation layer 130 includes but is not limited to sponge and foam.

[0111] In some embodiments, a second insulation layer 140 is provided between the indoor bottom plate 900 and the base plate 100. The second insulation layer 140 separates the indoor side from the base plate 100, thereby improving the insulation effect between the indoor side and the indoor, and reducing the impact on the temperature of the indoor side after heat exchange by the indoor heat exchanger 300.

[0112] In some embodiments, the second thermal insulation layer 140 is located between the substrate 100 and the indoor bottom plate 900 .

[0113] In some embodiments, the second temperature insulation layer 140 is surrounded by the third flange 901 .

[0114] In some embodiments, the substrate 100, the second insulation layer 140 and the indoor bottom plate 900 are respectively penetrated and correspond to the first air outlet, the second air outlet and the third air outlet. The airflow after heat exchange by the indoor heat exchanger 300 passes through the third air outlet, the second air outlet and the first air outlet in sequence and is output to the room.

[0115] In some embodiments, the edge of the substrate 100 near the first air outlet is bent toward one side of the indoor bottom plate 900 to form a fourth flange 110. Even if some accumulated water flows into the indoor substrate 100, the accumulated water is blocked by the fourth flange 110 to prevent the accumulated water from entering the room through the first air outlet, thereby improving the user experience.

[0116] In some embodiments, the fourth flange 110 is formed by bending the substrate 100 , and the fourth flange 110 is perpendicular to the substrate 100 .

[0117] The fourth flange 110 extends toward the indoor bottom plate 900 .

[0118] In some embodiments, the fourth flange 110 is attached to the thickness surface of the second thermal insulation layer 140 through which the second air outlet is penetrated.

[0119] In some embodiments, the substrate 100, the second insulation layer 140 and the indoor bottom plate 900 are respectively penetrated and correspond to the first air inlet, the second air inlet and the third air inlet. Indoor air enters the indoor side through the first air inlet, the second air inlet and the third air inlet.

[0120] In some embodiments, the edge of the substrate 100 near the first air inlet is bent toward one side of the indoor bottom plate 900 to form a fifth flange 120. Even if some accumulated water flows into the indoor substrate 100, the accumulated water is blocked by the fifth flange 120 to prevent the accumulated water from entering the room through the first air inlet, thereby improving the user experience.

[0121] In some embodiments, the fifth flange 120 is formed by bending the substrate 100 , and the fifth flange 120 is perpendicular to the substrate 100 .

[0122] The fifth flange 120 extends toward the indoor bottom plate 900 .

[0123] In some embodiments, the fifth flange 120 is attached to the thickness surface of the second thermal insulation layer 140 through which the second air inlet passes.

[0124] In some embodiments, the distance of the fourth flange 110 away from the substrate 100 is the same as the distance of the fifth flange 120 away from the substrate 100, so as to avoid the barrel effect.

[0125] In some embodiments, the partition 700 is bent and has multiple bent sections, so that the shapes of the indoor side and the outdoor side can be set according to needs. The first insulation layer 130 also corresponds to the bending of the partition 700.

[0126] In some embodiments, an indoor fan 500 is provided on the indoor side. Under the action of the indoor fan 500, the indoor air flow enters the indoor side through the first air inlet, the second air inlet and the third air inlet in sequence, and the air entering the indoor side is heat-exchanged by the indoor heat exchanger 300, and then, under the action of the indoor fan 500, it passes through the third air outlet, the second air outlet and the first air outlet in sequence and is output to the indoor side.

[0127] In some embodiments, an outdoor fan 600 is provided on the outdoor side, and an outdoor vent is penetrated on the casing 200 . The outdoor fan 600 is used to blow air through the outdoor heat exchanger 400 to achieve heat exchange of the refrigerant passing through the outdoor heat exchanger 400 .

[0128] In some embodiments, the outdoor vent extends through the top of the housing 200 .

[0129] In some embodiments, a grille is provided at the outdoor vent to prevent foreign matter from falling into the outdoors through the outdoor vent and causing damage to the outdoor fan 600 .

[0130] In addition, the present application also provides a rooftop unit, which includes: a base plate 100, a housing 200, a partition 700, an indoor heat exchanger 300, an outdoor heat exchanger 400 and an outdoor bottom plate 800; the housing 200 is open on one side of the base plate 100, and the housing 200 is disposed on the base plate 100. The base plate 100 closes the housing 200.

[0131] The partition plate 700 is disposed in the casing 200 , and is used to separate the interior of the casing 200 into an indoor side and an outdoor side.

[0132] The indoor heat exchanger 300 is arranged on the indoor side; the outdoor heat exchanger 400 is arranged on the outdoor side. The indoor heat exchanger 300 and the outdoor heat exchanger 400 are connected by a pipeline. A refrigerant flows between the indoor heat exchanger 300 and the outdoor heat exchanger 400 to achieve heat exchange for the air flow passing through the indoor heat exchanger 300 and the outdoor heat exchanger 400.

[0133] The side of the partition 700 close to the substrate 100 is bent toward the outdoor side to form a first flange 701; the outdoor bottom plate 800 is arranged on the outdoor side and attached to the substrate 100; the side of the outdoor bottom plate 800 close to the partition 700 is bent away from the substrate 100 to form a second flange 801.

[0134] The first flange 701 is clamped between the outdoor bottom plate 800 and the base plate 100 ; the second flange 801 is attached to the side of the partition plate 700 facing the outdoor side.

[0135] Through the above solution, the partition 700 is tightly connected to the indoor bottom plate 900 through the first flange 701 and the second flange 801 to prevent the outdoor water from flowing to the indoor side through the gap between the indoor bottom plate 900 and the partition 700.

[0136] Even if some of the accumulated water enters between the partition 700 and the indoor bottom plate 900, the water level on the outdoor side must be higher than the first flange 701 and the second flange 801 to flow into the indoor side, which is more difficult, further preventing the accumulated water on the outdoor side from flowing into the indoor side; thereby preventing the accumulated water from entering the room and affecting the users, thereby improving the user experience.

[0137] In some embodiments, the partition 700 is perpendicular to the substrate 100, and the bottom of the partition 700 is close to and used to fit the substrate 100. The first flange 701 is perpendicular to the partition 700, and the bottom surface of the first flange 701 is parallel to and fits the substrate 100. The outdoor bottom plate 800 and the substrate 100 clamp the first flange 701.

[0138] In some embodiments, a receiving cavity is provided on the substrate 100 for accommodating the first flange 701 .

[0139] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
