Description

Technical Field

[0001] The utility model relates to the field of evaporators, in particular to an evaporator, a heat exchange main unit and an air conditioner. Background Art

[0002] The indoor unit of the air conditioner is part of the air conditioning system. Its main function is to adjust the temperature of the indoor air by cooling or heating. Specifically, the indoor unit of the air conditioner mainly includes components such as the evaporator, fan, water tray and shell. The evaporator is an important part of the indoor unit of the air conditioner. It is a heat exchanger that adjusts the temperature of the air by absorbing and releasing heat. The V-shaped evaporator is a common type. It consists of two evaporator components spliced ​​at a certain angle and connected by a triangular connecting plate. This evaporator design can increase the heat exchange area and improve the heat exchange effect.

[0003] The fan is another important component. When it is running, it creates negative pressure, so that air is sucked in from the air inlet of the indoor unit and blown out from the air outlet after heat exchange in the evaporator. The operation of the fan can force air flow and improve the heat exchange effect.

[0004] The water tray and housing are also important components of the indoor unit of the air conditioner. The water tray is used to collect condensed water to prevent condensed water from accumulating inside the indoor unit. The housing is the outer shell of the indoor unit, protecting the internal components and providing certain support and aesthetics.

[0005] As the height of the existing V-shaped evaporator increases, the space required becomes larger. This is mainly because as the height of the evaporator increases, the heat exchange area will also increase accordingly, and more space is needed to accommodate these evaporator components. Therefore, the existing V-shaped evaporator has certain limitations in design, that is, as the height increases, the size of the water tray and its matching shell will also increase, resulting in a decrease in space utilization.

[0006] In addition, when the evaporator reaches a certain height, the closer it is to the fan volute, the easier it is for condensed water to splash and blow out of the water tray when the indoor unit is installed horizontally. This is because when the indoor unit is installed horizontally, the position of the water tray is relatively low, and when the height of the evaporator increases, the amount of condensed water generated will also increase accordingly. Due to the operation of the fan, the condensed water is easily blown out of the water tray, resulting in condensation problems.

[0007] In summary, the existing V-shaped evaporator has the problem of low space utilization in design. In order to solve these problems, it is possible to consider optimizing the structure of the evaporator to improve the space utilization. Utility Model Content

[0048] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0049] The principle and structure of the present utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0050] The indoor unit of the air conditioner is part of the air conditioning system. Its main function is to adjust the temperature of the indoor air by cooling or heating. Specifically, the indoor unit of the air conditioner mainly includes components such as the evaporator, fan, water tray and shell. The evaporator is an important part of the indoor unit of the air conditioner. It is a heat exchanger that adjusts the temperature of the air by absorbing and releasing heat. The V-shaped evaporator is a common type. It consists of two evaporator components spliced ​​at a certain angle and connected by a triangular connecting plate. This evaporator design can increase the heat exchange area and improve the heat exchange effect.

[0051] The fan is another important component. When it is running, it creates negative pressure, so that air is sucked in from the air inlet of the indoor unit and blown out from the air outlet after heat exchange in the evaporator. The operation of the fan can force air flow and improve the heat exchange effect.

[0052] The water tray and housing are also important components of the indoor unit of the air conditioner. The water tray is used to collect condensed water to prevent condensed water from accumulating inside the indoor unit. The housing is the outer shell of the indoor unit, protecting the internal components and providing certain support and aesthetics.

[0053] like Figure 1-2 As shown, as the height of the existing V-shaped evaporator 01 increases, the space required becomes larger. This is mainly because as the height of the evaporator increases, the heat exchange area will also increase accordingly, and more space is required to accommodate these evaporator components. Therefore, the existing V-shaped evaporator 01 has certain limitations in design, that is, as the height increases, the size of the water tray and its matching shell will also increase, resulting in a decrease in space utilization.

[0054] In addition, when the evaporator reaches a certain height, the closer it is to the fan volute, the easier it is for condensed water to splash and blow out of the water tray when the indoor unit is installed horizontally. This is because when the indoor unit is installed horizontally, the position of the water tray is relatively low, and when the height of the evaporator increases, the amount of condensed water generated will also increase accordingly. Due to the operation of the fan, the condensed water is easily blown out of the water tray, resulting in condensation problems.

[0055] In summary, the existing V-shaped evaporator 01 has a problem of low space utilization in design. In order to solve these problems, it is possible to consider optimizing the structure of the evaporator to improve the space utilization.

[0056] like Figure 3 As shown, the utility model provides an evaporator, comprising: an evaporator group 1, two connecting plates 3 and a water baffle 2.

[0057] Evaporator group 1, evaporator group 1 includes a plurality of straight-plate evaporators, the plurality of straight-plate evaporators are sequentially spliced ​​end to end to form an M shape, and each straight-plate evaporator is arranged obliquely;

[0058] Two connecting plates 3 cover opposite sides of the evaporator group 1 and form an air inlet cavity with the evaporator group 1 for bottom air inlet;

[0059] The water baffle 2 is arranged on the top of the straight plate type evaporator.

[0060] Specifically, the evaporator group 1 is the main body of the whole, which is composed of a plurality of straight-plate evaporator groups 1. The evaporator is a device generally used for heat exchange, and the straight-plate type refers to its shape, which is a straight flat plate shape. A plurality of straight-plate evaporators are spliced ​​end to end in sequence, and the shape is M-shaped. Each straight-plate evaporator is arranged at an angle so that the liquid flow on the evaporator can flow out from one end of the evaporator. There are two connecting plates 3, which cover the opposite sides of the M-shaped side of the evaporator group 1, and form an air inlet cavity for bottom air intake with the evaporator group 1. The connecting plate 3 is also used to connect and fix the evaporator group 1. The water baffle 2 is arranged on the top of the straight-plate evaporator. Its main function may be to prevent liquid or water from directly evaporating or splashing out of the evaporator to ensure the efficiency of heat exchange.

[0061] In a further embodiment, the evaporator group 1 is formed by splicing four straight-plate evaporators of the same length.

[0062] Specifically, there are four straight-plate evaporators of the same length. These evaporators have the same size and can be spliced ​​together. The four straight-plate evaporators are spliced ​​in a head-to-tail manner. That is, the top of the first evaporator is connected to the top of the second evaporator, the bottom of the second evaporator is connected to the top of the third evaporator, and the top of the third evaporator is connected to the top of the fourth evaporator. In this head-to-tail manner, the four straight-plate evaporators form a continuous, M-shaped evaporator group 1. It helps to distribute the heat exchanged gas more evenly, thereby providing a higher heat exchange efficiency.

[0063] In a further embodiment, the evaporator group 1 includes: two first straight plate type evaporators and two second straight plate type evaporators, the length of the first straight plate type evaporator is greater than the length of the second straight plate type evaporator, the two first straight plate type evaporators are located on the outside, and the two second straight plate type evaporators are located on the inside and spliced ​​into a V shape, and the bottom position of the two second straight plate type evaporators is higher than the bottom position of the two first straight plate type evaporators.

[0064] Specifically, there are two different straight-plate evaporators in the evaporator group 1, namely, a first straight-plate evaporator and a second straight-plate evaporator. The length of the first straight-plate evaporator is greater than that of the second straight-plate evaporator. The two first straight-plate evaporators are located on the outside, and the two second straight-plate evaporators are located on the inside and spliced ​​into a V shape, and spliced ​​into an M shape with the straight-plate evaporators on the outside, so as to enhance the heat exchange efficiency. And the bottom positions of the two second straight-plate evaporators are higher than the bottom positions of the two first straight-plate evaporators. It is convenient for installation.

[0065] In a further embodiment, the edge of the water retaining plate 2 on the top of the straight-plate type evaporator extends out of the top surface of the evaporator to form a circle of water retaining edge.

[0066] Specifically, a water retaining plate 2 is provided on the top of the straight-plate evaporator, and the edge of the water retaining plate 2 extends out of the top surface of the evaporator to form a circle of water retaining edge. When the evaporator is placed to let in air, the condensed water on the evaporator is splashed by the air.

[0067] In a further embodiment, two opposite sides of the straight plate type evaporator are provided with fixed folding edges, and the connecting plate 3 is connected to the fixed folding edges by screws.

[0068] The connecting plate 3 is connected to the fixed folded edge by screws. This connection method allows the connecting plate 3 and the evaporator to be easily installed and disassembled, while also ensuring that the connection between them is firm and reliable.

[0069] In a further embodiment, a splicing edge is provided on the splicing side of the top of the straight-plate type evaporator, and the top splicing edges of two adjacent straight-plate type evaporators are overlapped and connected by screws.

[0070] Each straight evaporator has an edge on the top that can be spliced ​​with the top of other straight evaporators. These splicing edges are used as fulcrums for connecting other components. After the top splicing edges of the two evaporators are aligned, they are fixed with screws or other similar fasteners. This connection method allows adjacent evaporators to be firmly connected together to form a stable and continuous evaporator group 1.

[0071] like Figure 4-8 As shown, the utility model also proposes a heat exchange main unit, including the evaporator of the utility model.

[0072] The heat exchanger host also includes:

[0073] The housing 4 has an air inlet and an air outlet 7 at the bottom and top of the housing 4 respectively;

[0074] A water receiving tray, which is arranged at the bottom of the housing 4, and an evaporator is installed on the water receiving tray;

[0075] The fan 6 is arranged in the housing 4 and above the evaporator.

[0076] Specifically, the shell 4 is the external structure of the heat exchange main unit, which wraps and protects the internal components. An air inlet is provided at the bottom of the shell 4, and air enters the shell 4 from this air inlet. An air outlet 7 is provided at the top of the shell 4, and the gas processed by the heat exchange main unit will be discharged from the air outlet 7. The water receiving pan is a structure for receiving condensed water, which is arranged at the bottom of the shell 4. An evaporator is installed on the water receiving pan. Any liquid flowing down from the evaporator will be captured by the water receiving pan. The presence of the water receiving pan helps to prevent liquid leakage or dripping, ensure the clean and safe operation of the heat exchange main unit, and conveniently collect and process the generated liquid. The fan 6 is a device for circulating air or gas. It is arranged in the shell 4 above the evaporator. When the fan 6 is working, it can push air from the air inlet into the evaporator and then be discharged from the air outlet 7, thereby realizing heat exchange.

[0077] In a further embodiment, the water receiving tray includes a main water receiving tray 51 and an auxiliary water receiving tray 5 .

[0078] A main water receiving tray 51 is provided with an evaporator. The main water receiving tray 51 is provided with a circle of inner baffles around the middle to form a vent 503, and a circle of outer baffles and the bottom plate to form a water receiving groove in the shape of a Chinese character U. A supporting bridge 501 is provided in the middle of the main water receiving tray 51 to cross the vent 503 and support the inner baffles on both sides. The supporting bridge 501 supports the bottom of the two straight-plate evaporators in the middle;

[0079] The auxiliary water receiving tray 5 is close to the inner wall of the vertical side of the shell 4, and the bottom of the auxiliary water receiving tray 5 is sleeved outside one end of the main water receiving tray 51.

[0080] In a further embodiment, a notch is provided on the bottom edge of the connecting plate 3 , which is connected to both ends of the supporting bridge 501 , so that the condensed water of the two middle straight-plate evaporators remains on the supporting bridge 501 and then flows from the notch to the main water receiving tray 51 .

[0081] like Figure 9-10 As shown, the utility model also provides an air conditioner, including the heat exchange main unit of the utility model.

[0082] Compared with the prior art, the utility model changes the original V-shape of the evaporator into an M-shape. Under the condition of the same heat exchange area, the height of the M-shaped evaporator is lower, and the matching water receiving tray is smaller, so the M-shaped evaporator occupies less space and has a higher space utilization rate. A water baffle 2 is provided on the top of the evaporator to prevent the condensed water on the evaporator from splashing due to the influence of the incoming wind.

[0083] It should be noted that the terms used above are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0085] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description.
