Description

Technical Field

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

[0002] Air conditioners are widely used to adjust the temperature of indoor environments. Specifically, an air duct is formed in the housing of the indoor unit of the air conditioner, and an evaporator installed in the air duct exchanges heat with the air flow passing through the air duct, thereby adjusting the temperature of the indoor environment. However, in some air conditioners in the prior art, the effective air inlet area of ​​the air duct is relatively small, resulting in low temperature adjustment efficiency of the air conditioner. Summary of the invention

[0003] The purpose of the present invention includes providing an air conditioner housing structure and an air conditioner to solve the technical problem that in some existing air conditioners, the effective air inlet area of ​​the air duct is relatively small, resulting in low temperature regulation efficiency of the air conditioner.

[0004] In order to solve the above problems, the present invention provides an air-conditioning shell structure, including a shell, wherein the shell includes a first accommodating chamber for accommodating an evaporating body in an evaporator and a second accommodating chamber for accommodating an electrical control box along its length direction, and the top plate of the shell is provided with an air inlet corresponding to the first accommodating chamber, and the area of ​​the top plate corresponding to the second accommodating chamber is a protective area, and the protective area is provided with a plurality of first air inlet holes.

[0005] When the air-conditioning shell structure provided by the present invention is applied to an air conditioner, firstly, the second accommodating chamber contains the electric control box and some refrigerant pipes connected to the evaporator end pipe and other components, the top plate and the protective area corresponding to the second accommodating chamber are in a non-open state, and the protective area provided with the first air inlet hole can still play a role in blocking and protecting the components in the second accommodating chamber, so as to reduce the collision damage to the electric control box and other components caused by external factors. Secondly, when the air conditioner is running, the air of the indoor environment flows into the shell through the air inlet and the first air inlet hole at the same time, wherein the airflow flowing in through the air inlet directly flows to the evaporation body as the main airflow and flows out of the shell after heat exchange with the evaporation body; the airflow flowing in through the first air inlet hole is turned inside the shell as the auxiliary airflow and flows to the evaporation body, and flows out of the shell after heat exchange with it. It can be seen that the setting of the first air inlet hole can effectively increase the effective air inlet area of ​​the air duct. When the operating power of the air conditioner is constant, the increase of the total air inlet area can effectively increase the air intake of the air conditioner, thereby improving the temperature regulation efficiency and temperature regulation performance of the air conditioner for the indoor environment; or, the operating power of the air conditioner can be reduced to maintain the same air intake, thereby maintaining the air conditioning The effect of regulating the temperature of the indoor environment reduces the power consumption of the air conditioner and extends the service life of various electrical components of the air conditioner. Thirdly, during the operation of the air conditioner, the auxiliary airflow can also exchange heat with the electric control box inside the first accommodating cavity during the process of flowing through the first accommodating cavity, thereby playing a role in heat dissipation and cooling the electric control box, correspondingly ensuring the normal operation of the electric control box, and then ensuring the normal use of the air conditioner.

[0006] Optionally, a protection plate is provided in the shell, and the protection plate is located between the first accommodating chamber and the second accommodating chamber and at the front side of the evaporator.

[0007] Optionally, the protective plate is provided with ventilation holes.

[0008] Optionally, the edge of the protective plate includes a top edge, a front edge and a rear edge in sequence along its circumference, the top edge is connected to the top plate, the front edge is connected to the front panel of the shell, and the rear edge is arranged parallel to the corresponding area of ​​the evaporation body and there is a ventilation gap between the two.

[0009] Optionally, a plurality of second air inlet holes are provided in an area of ​​the side plate of the shell above the evaporator.

[0010] Optionally, a filter is provided at the air inlet.

[0011] Optionally, the filter screen includes a first filter area blocked outside the air inlet and a second filter area blocked outside the protection area.

[0012] Optionally, the inner area of ​​the annular edge of the top plate is concave to form a limiting groove, and the air inlet and the protection area are both located at the bottom of the limiting groove; the filter is matched and embedded in the limiting groove.

[0013] Optionally, the filter net includes a frame and a plurality of first filter strips and a plurality of second filter strips arranged in the frame, wherein the plurality of first filter strips extend in the left-right direction and are arranged at intervals in the front-to-back direction, and the plurality of second filter strips extend in the front-to-back direction and are arranged at intervals in the left-to-right direction; a plurality of support ribs are connected between the two side walls opposite to each other of the air inlet, and the plurality of support ribs correspond one-to-one to the plurality of first filter strips and / or the plurality of second filter strips.

DETAILED DESCRIPTION

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] This embodiment provides an air conditioner housing structure, such as Figure 2 and Figure 3 As shown, it includes a shell 100, and the shell 100 includes a first accommodating chamber 110 for accommodating an evaporating body in the evaporator and a second accommodating chamber 120 for accommodating an electric control box along its length direction. The top plate 130 of the shell 100 is provided with an air inlet 131 corresponding to the first accommodating chamber 110, and the area corresponding to the top plate 130 and the second accommodating chamber 120 is a protective area 132, and the protective area 132 is provided with a plurality of first air inlet holes 132a.

[0024] This embodiment also provides an air conditioner, including an evaporator, an electric control box and the above-mentioned air conditioner shell structure, the evaporation body of the evaporator is accommodated in the first accommodation cavity of the shell 100, and the electric control box is accommodated in the second accommodation cavity.

[0025] The present embodiment provides an air conditioning shell structure and an air conditioner, wherein the air conditioning shell structure includes a shell 100 for forming an air duct internally, and the top plate 130 of the shell 100 is provided with an air inlet 131 as an air inlet port of the air duct and a first air inlet hole 132a for auxiliary air intake; wherein the air conditioner includes the above-mentioned air conditioning shell structure, an evaporator for regulating the heat of the air flow passing through the air duct, and an electric control box for electric control, and the evaporating body of the evaporator is located in a first accommodating chamber corresponding to the air inlet 131, and the electric control box is located in a second accommodating chamber corresponding to the first air inlet hole 132a.

[0026] First, the second accommodating chamber 120 contains components such as an electrical control box and some refrigerant pipes connected to the evaporator end pipes. The top plate 130 and the corresponding protective area 132 of the second accommodating chamber 120 are not open. The protective area 132 with the first air inlet hole 132a can still play a shielding and protective role for the components in the second accommodating chamber 120, so as to reduce collision damage to components such as the electrical control box caused by external factors. Secondly, when the air conditioner is running, the air of the indoor environment flows into the shell 100 through the air inlet 131 and the first air inlet hole 132a at the same time, wherein the airflow flowing in through the air inlet 131 directly flows to the evaporation body as the main airflow and flows out of the shell 100 after heat exchange with the evaporation body; the airflow flowing in through the first air inlet hole 132a is turned inside the shell 100 as the auxiliary airflow and flows to the evaporation body, and flows out of the shell 100 after heat exchange with the evaporation body. It can be seen that the setting of the first air inlet hole 132a can effectively increase the effective air inlet area of ​​the air duct. When the operating power of the air conditioner is constant, the increase in the total air inlet area can effectively increase the air intake of the air conditioner, thereby improving the temperature regulation efficiency and temperature regulation performance of the air conditioner for the indoor environment; alternatively, the operating power of the air conditioner can be reduced to maintain the same air intake, thereby reducing the power consumption of the air conditioner and extending the service life of various electrical components of the air conditioner while maintaining the temperature regulation effect of the air conditioner on the indoor environment. Thirdly, during the operation of the air conditioner, the auxiliary airflow can also exchange heat with the electric control box inside the first accommodating chamber 110, thereby dissipating heat and cooling the electric control box, thereby ensuring the normal operation of the electric control box and further ensuring the normal use of the air conditioner.

[0027] Specifically, a plurality of first air inlet holes 132a may be arranged on the top plate 130 in a rectangular array or a plurality of nested annular arrays.

[0028] Optionally, in this embodiment, if Figure 3 As shown, a protective plate 140 can be provided in the housing 100, and the protective plate 140 is located between the first accommodating chamber 110 and the second accommodating chamber 120 and is located at the front side of the evaporator. Firstly, the protective plate 140 plays a partial blocking role for the first accommodating chamber 110 and the second accommodating chamber 120, thereby playing a blocking and protective role for the components such as the electric control box located in the second accommodating chamber 120 at the front side, and the auxiliary airflow entering the second accommodating chamber 120 through the first air inlet hole 132a can flow to the first accommodating chamber 110 through the area outside the protective plate, and the effectiveness of the first air inlet hole 132a is accordingly ensured; secondly, the provision of the protective plate 140 can play the role of a reinforcing rib, thereby improving the overall strength of the housing 100, so as to ensure the stability of the shape of the housing 100 and the stability of the bearing components.

[0029] Optionally, in this embodiment, if Figure 3As shown, ventilation holes 141 can be provided on the protective plate 140. Firstly, after the ventilation holes 141 are provided on the protective plate 140, the front area of ​​the first accommodating chamber 110 and the second accommodating chamber 120 can still be shielded and protected; secondly, during the operation of the air conditioner, the auxiliary airflow entering the air duct through the first air inlet hole 132a can flow to the evaporating body through the area other than the protective plate 140 to achieve heat exchange, and can also flow directly to the front side of the evaporating body through the ventilation holes 141 on the protective plate 140, and then flow through the evaporating body and flow out of the housing 100 after heat exchange. It can be seen that the provision of the ventilation holes 141 can not only increase the flow area of ​​the auxiliary airflow flowing to the evaporating body, but also the increased flow area is an effective area located in the front side of the evaporating body that can effectively exchange heat with the evaporating body, thereby greatly improving the effectiveness of the auxiliary airflow in temperature regulation, and correspondingly further improving the temperature regulation effect of the air conditioner indoor unit and the air conditioner on the indoor environment.

[0030] Specifically, in this embodiment, Figure 3 As shown, the edge of the protective plate 140 includes a top edge, a front edge 142 and a rear edge 143 in sequence along its circumference, the top edge is connected to the top plate 130, the front edge 142 is connected to the front panel 150 of the housing 100, and the rear edge 143 is arranged in parallel with the corresponding area of ​​the evaporation body and there is a ventilation gap between the two. The protective plate 140 blocks the front side of the evaporator. On the one hand, the setting of the ventilation gap can further increase the effective flow area of ​​the auxiliary airflow on the front side of the evaporation body on the basis of enabling the protective plate 140 to still play a blocking and protective role, thereby further improving the effectiveness of the auxiliary airflow in temperature regulation, and correspondingly further improving the temperature regulation effect of the air conditioner on the indoor environment. On the other hand, the width of the ventilation gap formed between the protective plate 140 and the corresponding evaporation plate of the evaporator is equal, and the airflow of the auxiliary airflow flowing to the front wall of the evaporation body through the ventilation gap is relatively uniform, thereby improving the airflow stability of the auxiliary airflow flowing to the front side of the evaporation body, reducing the airflow disturbance caused by the auxiliary airflow to the main airflow, and correspondingly improving the effective heat exchange flow of the main airflow and the auxiliary airflow with the evaporation body, and reducing the noise pollution caused by the airflow disturbance; preferably, the ventilation gap can be the maximum width that meets the safety regulations. Compared with the irregular rear edge 143, the ventilation gap widths are equal and are both the maximum widths that meet the requirements. Then, the effective flow area increased by the ventilation gap on the front side of the evaporation body is the largest, and the corresponding degree of improvement in the temperature regulation performance of the air conditioner is relatively high.

[0031] In this embodiment, Figure 3As shown, the side plate 160 of the housing 100 is provided with a plurality of second air inlet holes 161 in the area above the evaporator. The second air inlet holes 161 are located above one end of the evaporating body in the length direction. When the air conditioner is running, in addition to the air inlet 131 and the first air inlet holes 132a, the air of the indoor environment can also flow directly toward the evaporating body to the upper side of the evaporating body through the second air inlet holes 161, thereby flowing through the evaporating body and effectively exchanging heat with it before flowing out of the housing 100. The provision of the second air inlet holes 161 can effectively increase the effective air inlet area of ​​the air duct, and correspondingly further increase the air intake of the air conditioner, thereby further improving the temperature regulation efficiency of the air conditioner for the indoor environment and the temperature regulation performance of the air conditioner.

[0032] Optionally, in this embodiment, if Figure 1 As shown, a filter 200 can be provided at the air inlet 131. The mesh of the filter 200 is smaller than the size of the air inlet 131, so that the airflow flowing into the air inlet 131 can be filtered to reduce the occurrence of large impurities entering the housing 100 through the air inlet 131 and causing blockage of the evaporator, fan, etc. therein, thereby ensuring the normal operation of the indoor unit of the air conditioner.

[0033] In this embodiment, Figure 1 As shown, the filter 200 includes a first filter area 210 that blocks the outside of the air inlet 131 and a second filter area 220 that blocks the outside of the protective area 132. The first filter area 210 of the filter 200 can filter the airflow flowing into the air inlet 131 to reduce the occurrence of large impurities flowing into the air inlet 131; at the same time, the second filter area 220 of the filter 200 can play a preliminary filtering role outside the protective area 132 to reduce impurities blocking the first air inlet 132a of the protective area 132, thereby ensuring effective air intake of the first air inlet 132a.

[0034] Specifically, in this embodiment, Figure 2 and Figure 3 As shown, the inner area of ​​the annular edge 133 of the top plate 130 is concave to form a limiting groove 134, and the air inlet 131 and the protection area 132 are both located at the bottom of the limiting groove 134; Figure 1As shown, the filter 200 is matched and embedded in the limiting groove 134. The setting of the limiting groove 134, on the one hand, can limit the position where the filter 200 is connected to the top plate 130, thereby improving the accuracy and convenience of the installation position of the filter 200, and ensuring the effective filtering effect of the filter 200 on the air inlet 131 and the first air inlet hole 132a; on the other hand, the filter 200 is embedded in the limiting groove 134, and the top surface of the filter 200 is not higher than the top plate 130. Preferably, the top surface of the filter 200 is in the same height as the top surface of the top plate 130, thereby improving the overall appearance of the top plate 130 and the housing 100, reducing the impact of the convexity of the filter 200 on the appearance of the top of the housing 100 and the occurrence of interference during the installation process.

[0035] Optionally, in this embodiment, if Figure 1 As shown, the filter net 200 includes a frame 230 and a plurality of first filter strips 240 and a plurality of second filter strips 250 arranged in the frame 230, wherein the plurality of first filter strips 240 all extend in the left-right direction and are arranged at intervals in the front-to-back direction, and the plurality of second filter strips 250 all extend in the front-to-back direction and are arranged at intervals in the left-to-right direction; a plurality of support ribs 135 are connected between the two side walls opposite to each other of the air inlet 131, and the plurality of support ribs 135 correspond one-to-one to the plurality of first filter strips 240 and / or the plurality of second filter strips 250. The frame 230 serves as a bearing and shaping frame for the first filter strip 240 and the second filter strip 250, and a plurality of first filter strips 240 and a plurality of second filter strips 250 that are spaced in parallel form a mesh body of regular shape; the support ribs 135 are supported on the two opposite side walls of the air inlet 131 to improve the strength of the top plate 130 and the shape stability of the air inlet 131, thereby ensuring the stability of the filter net 200 connected to the top plate 130 and the effective filtering of the air inlet 131 and the first air inlet hole 132a by the filter net 200; in addition, the support ribs 135 are located at the bottom of the first filter strip 240 or the second filter strip 250, and the setting of the support ribs 135 and the first filter strip 240 or the second filter strip 250 only cause one shielding of the air inlet 131, and will not cause additional shielding of the air inlet 131, thereby reducing the reduction of the air inlet area of ​​the air inlet 131 caused by the support ribs 135, and correspondingly ensuring the effective air inlet area of ​​the air inlet 131. Preferably, the limiting groove 134 is rectangular, and the frame 230 is also rectangular accordingly. The supporting rib 135 can extend in the front-to-back direction to effectively support the air inlet 131 with a shorter length and higher strength.

[0036] Specifically, in this embodiment, Figure 2 and Figure 3As shown, an overlapping edge 134a is left between the air inlet 131 and the side wall of the limiting groove 134. When the filter 200 is installed in the limiting groove 134, the overlapping edge 134a and the protective area 132 can abut and limit the frame 230 of the filter 200, thereby improving the stability of the filter 200 connected to the top plate 130 and reducing the occurrence of the filter 200 being inserted into the shell 100 from the air inlet 131.
