[0067] The disclosure below provides many different embodiments or examples to realize different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplicity and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0068] In the present application, the air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to cool or heat the indoor space.

[0069] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0070] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0071] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner performs a heating mode; when the indoor heat exchanger functions as an evaporator, the air conditioner performs a cooling mode.

[0072] Among them, the indoor heat exchanger and the outdoor heat exchanger are converted to serve as a condenser or an evaporator, generally using a four-way valve. Please refer to the settings of conventional air conditioners for details, which will not be elaborated here.

[0073] The refrigeration working principle of the air conditioner is: the operation of the compressor makes the indoor heat exchanger (in the indoor unit, it is the evaporator at this time) in an ultra-low pressure state, the liquid refrigerant in the indoor heat exchanger evaporates rapidly to absorb heat, and the wind blown out by the indoor fan is cooled by the indoor heat exchanger coil and becomes cold air blown into the room. The evaporated refrigerant is pressurized by the compressor and condensed into liquid under the high-pressure environment of the outdoor heat exchanger (in the outdoor unit, it is the condenser at this time), releasing heat, and dissipating the heat into the atmosphere through the outdoor fan. This cycle achieves the cooling effect.

[0074] The heating working principle of the air conditioner is as follows: the gaseous refrigerant is pressurized by the compressor, becomes a high-temperature and high-pressure gas, enters the indoor heat exchanger (the condenser at this time), condenses and liquefies to release heat, becomes a liquid, and heats the indoor air at the same time, thereby achieving the purpose of raising the indoor temperature. The liquid refrigerant is decompressed by the throttling device and enters the outdoor heat exchanger (the evaporator at this time), evaporates and absorbs heat to become a gas, and at the same time absorbs the heat of the outdoor air (the outdoor air becomes colder), becomes a gaseous refrigerant, and enters the compressor again to start the next cycle.

[0075] The air-conditioning indoor unit in the present embodiment is an all-in-one fresh air and environmental control unit, which includes a casing body 100, wherein an installation cavity is formed in the casing body 100, and the bottom of the installation cavity is open. A plurality of installation areas are separated in the installation cavity by a partition structure for respectively installing a heat exchange core, a heat exchanger, a fan and other components. At the same time, a plurality of air ducts are defined by the partition structure. For example, the air duct may include an outdoor fresh air duct, an indoor circulating air duct, and an indoor exhaust air duct, etc. A plurality of air outlets are arranged on the casing body. For example, the air outlet may include a fresh air inlet, a fresh air outlet, an exhaust air inlet, an exhaust air outlet, a circulating air inlet, etc. Through the layout arrangement of the heat exchange core, the heat exchanger, the fan, a plurality of air ducts, and a plurality of air outlets, the all-in-one fresh air and environmental control unit can meet the needs of indoor air temperature regulation, fresh air introduction, indoor air circulation, indoor exhaust and the like.

[0076] Figures 1 to 4 The structure shown omits components such as the internal air duct, heat exchange core, heat exchanger, and air duct, and only shows the casing body 100, the partition portion 200, the first bottom panel 310, and the second bottom panel 320, etc., which are related to the innovative improvements of the present invention.

[0077] When the fresh air environment control integrated machine is in normal use, the installation direction is as follows: Figure 1 and Figure 2 As shown, the bottom panel is located underneath.

[0078] When assembling the fresh air environment control integrated machine, the assembly orientation is as follows Figure 3 and Figure 4 As shown, the casing body 100 is placed on a workbench with the opening facing upward, and the heat exchange core, heat exchanger, fan, partition assembly and other components are first installed in the installation cavity of the casing body 100, and finally the first bottom panel 310 and the second bottom panel 320 are installed.

[0079] For ease of description, Figure 1 Taking the orientation of the fresh air environment control integrated machine in normal use as an example, six orientations are defined: front, back, left, right, top, and bottom.

[0080] Different from the whole bottom panel structure in the prior art, the bottom panel in this embodiment is two independent split structures, including a first bottom panel 310 and a second bottom panel 320. A maintenance port 400 can be set on each bottom panel to facilitate maintenance of functional components in the corresponding coverage area.

[0081] How to achieve independent and convenient disassembly and assembly of the two bottom panels is one of the technical problems that need to be solved in this application.

[0082] Reference Figure 3The partition part 200 is arranged in the installation cavity, dividing the installation cavity into a first installation cavity 131 and a second installation cavity 132 arranged on the left and right. The two installation cavities can be used to install the heat exchange core and the heat exchanger respectively. The partition part 200 can also be used as an installation carrier for other components (such as a fan, etc.) at the same time.

[0083] The first bottom panel 310 is disposed at the bottom opening of the first installation cavity 131 to block the bottom opening of the first installation cavity 131. The second bottom panel 320 is disposed at the bottom opening of the second installation cavity 132 to block the bottom opening of the second installation cavity 132.

[0084] The partition part 200 not only plays a role in separating the chambers, but is also used to connect and fix the first bottom panel 310 and the second bottom panel 320 .

[0085] The first bottom panel 310 and the second bottom panel 320 are respectively rectangular structures, and reliable fixing and installation of the two involves installation of their respective four sides.

[0086] The first bottom panel 310 and the second bottom panel 320 are respectively fixed with the partition part 200 by plugging in the side close to the partition part 200, the front / rear sides of the first bottom panel 310 and the second bottom panel 320 are fixed with the front / rear side walls of the casing body 100 by snapping in the fixing structure, and the left / right sides of the first bottom panel 310 and the second bottom panel 320 are fixed with the left / right side walls of the casing body 100 by screws. The specific assembly structure of each side is described in detail below.

[0087] The plug-in fixing structure between the first bottom panel 310, the second bottom panel 320 and the partition part 200 is specifically as follows:

[0088] The structure of the partition part 200 is as follows Fig.12 As shown, Fig.12 The placement posture of the partition part 200 in the figure is the placement posture of the fresh air environment control integrated machine during assembly production. Figure 1 The fresh air and environmental control integrated machine shown in the figure is described by its orientation during normal use. A first slot 210 is provided at the bottom of the partition portion 200. The first slot 210 extends along the length direction of the partition portion 200. The plug of the first slot 210 faces the first installation cavity 131, and the wall surrounding the first slot 210 protrudes toward one side of the second installation cavity 132.

[0089] The first slot 210 is composed of a plurality of bent flanges. The first slot 210 and the partition portion 200 are bent from the same sheet of material. The first slot 210 serves to simultaneously install the first bottom panel 310 and the second bottom panel 320 .

[0090] The structure of the first bottom panel 310 is as follows: Figures 5 to 7As shown, the first bottom panel 310 is provided with an inserting portion 311 on one side close to the partition portion 200, referring to Fig.14 The plug-in portion 311 is plugged into the first slot 210 .

[0092] The plug-in portion 311, the first slot 210, and the second slot 321 are superimposed on each other, but are independent of each other. The first slot 210 on the partition portion 200 can be used to realize the separate assembly and disassembly of the two bottom panels without affecting each other. In order to ensure tight assembly, the three are appropriately interference fit.

[0093] The clamping and fixing structure between the first bottom panel 310, the second bottom panel 320 and the front / rear side wall of the housing body 100 is specifically as follows:

[0094] The structure of the housing body 100 is as follows Fig.11 As shown, Fig.11 The placement posture of the housing body 100 in the figure is the placement posture of the fresh air environment control integrated machine during assembly production. Figure 1 The fresh air environment control integrated machine is described in the normal use direction shown in the figure, and then refer to Fig.16 The bottoms of the front side wall and the rear side wall of the casing body 100 are respectively provided with first flanges 181 , and the first flanges 181 are provided with a socket 190 .

[0095] Reference Figure 5 and Figure 6 ,as well as Figure 8 and Fig. 9 , and then combine Fig.15 and Fig.16 A second flange 340 is respectively provided on the front side and the rear side of the first bottom panel 310 and the second bottom panel 320 , and a snap-in portion 330 is provided on the second flange 340 . The first flange 181 is in contact with the second flange 340 , and the snap-in portion 330 is snapped into the corresponding socket 190 .

[0096] The screw fixing structure between the first bottom panel 310, the second bottom panel 320 and the left / right side wall of the housing body 100 is as follows:

[0097] The right side of the first bottom panel 310 and the left side of the second bottom panel 320 are respectively provided with vertically extending connecting flanges 370, and the connecting flanges 370 are fixedly connected to the left and right walls of the housing body 100 by connecting members (such as screws). Figure 5 The screw fixing structure between the right side wall of the housing body 100 is shown in FIG. Fig.18 The connecting flange 370 on the second bottom panel 320 is shown in FIG. Figure 8 The screw fixing structure between the left wall of the housing body 100 is shown in FIG. Fig.19 .

[0098] The installation process of the first bottom panel 310 and the second bottom panel 320 is as follows: Figure 4 , and Figure 4 Taking the shown orientation as an example, the two bottom panels are dropped down to the top of the casing body 100; the snap-in portion 330 on the first bottom panel 310 is snap-fitted with the corresponding socket 190, the plug-in portion 311 on the first bottom panel 310 is inserted into the first slot 210 on the partition portion 200, and then the right side connecting flange 370 of the first bottom panel 310 is fixed to the right side wall of the casing body 100 by screws, thus completing the fixed installation of the first bottom panel 310; the snap-in portion 330 on the second bottom panel 320 is snap-fitted with the corresponding socket 190, the second slot 321 on the second bottom panel 320 is plugged into the wall of the first slot 210 on the partition portion 200, and then the left side connecting flange 370 of the second bottom panel 320 is fixed to the left side wall of the casing body 100 by screws, thus completing the fixed installation of the second bottom panel 320.

[0099] There is no distinction between the first bottom panel 310 and the second bottom panel 320 for assembly. The two can be assembled independently of each other, and can also be disassembled independently of each other without affecting each other.

[0100] exist Figure 1 In the usage posture shown, the bottom panel serves as the main surface of the fresh air and environmental control integrated machine, and there are no exposed screws on it.

[0101] The first bottom panel 310 is screwed only on the right side, and the second bottom panel 320 is screwed only on the left side. No screws are required at other places. The two bottom panels can be installed only through mechanical clipping and plug-in structures, and by utilizing the structural improvements of the casing body 100 and the partition part 200, thereby greatly improving the installation efficiency and assembly reliability.

[0102] In some embodiments of the present application, refer to Figure 7 , Fig.10 ,as well as Fig.16 A third flange 350 is respectively provided on the front / rear edges of the first bottom panel 310 and the second bottom panel 320, and the third flange 350 extends along the vertical direction toward the side close to the casing body 100. The second flange 340 extends horizontally from the third flange 350 toward the inner side of the installation cavity. A notch 341 is provided on the second flange 340, and the notch 341 is open toward one side of the installation cavity. The clamping portion 330 is provided at the notch 341.

[0103] Grooves (not shown) for installing the insulation layer are formed between the second flange 340 and the first bottom panel 310 and between the second flange 340 and the second bottom panel 320, respectively, to facilitate the installation of the insulation layer. In addition, the front / rear sides of the two bottom panels are formed into two bending structures through the second flange 340 and the third flange 350, which helps to improve the structural strength.

[0104] Reference Figure 6 and Fig. 9 , combined with Fig.16 The clamping portion 330 includes a clamping transverse portion I331, a clamping vertical portion 332, and a clamping transverse portion II333 which are connected in sequence. The extension direction of the clamping transverse portion I331 and the clamping transverse portion II333 is the same as the extension direction of the second flange 340. The clamping vertical portion 332 is connected between the clamping transverse portion I331 and the clamping transverse portion II333. The clamping transverse portion I331 extends from one side of the notch 341 toward the center of the notch 341, and the clamping vertical portion 332 extends from the clamping transverse portion I331 toward the side close to the first flange 181.

[0105] When installing the first bottom panel 310 and the second bottom panel 320, refer to Figure 4 and Fig.16 , drop the first bottom panel 310 and the second bottom panel 320 down to the top of the casing body 100, the second flange 340 drops to the top of the first flange 181, and the snap-on portion 330 falls into the corresponding socket 190, and then push the two bottom panels toward one side of the partition portion 200 respectively, the second flange 340 slides along the first flange 181, and after being pushed into place, one side edge of the socket 190 abuts against the snap-on vertical portion 332, the second flange 340 abuts against the bottom side of the first flange 181, and the snap-on horizontal portion II 333 abuts against the upper side of the first flange 181.

[0106] The structural arrangement of the snap-on portion 330 and the socket 190 enables the snap-on portion 330 to fall into the corresponding socket 190 when the two bottom panels are placed on the top of the casing body 100 from top to bottom, and then the two bottom panels can be pushed horizontally to achieve reliable snap-on connection between the snap-on portion 330 and the socket 190, thereby facilitating installation; and the second flange 340 and the snap-on portion 330 are located on the upper and lower sides of the first flange 181, and are staggered in the upper and lower directions, so that the structure is reliable.

[0107] In some embodiments of the present application, refer to Figure 6 and Fig.15 The clamping portion 330 also includes a clamping inclined portion 334, which extends obliquely from the clamping transverse portion II 333 toward a side away from the notch 341. The clamping inclined portion 334 serves as an installation guide for the process of the clamping portion 330 being clamped into the socket 190.

[0108] In some embodiments of the present application, from Figure 5 and Figure 6 ,as well as Figure 8 and Fig. 9 It can be seen that the clamping portions 330 disposed on the first bottom panel 310 and the second bottom panel 320 face in opposite directions and both point toward the partition portion 200 .

[0109] When installing the first bottom panel 310, the first bottom panel 310 is pushed along the bottom opening of the first installation cavity 131 toward the direction close to the partition portion 200, and relative sliding occurs between the first flange 181 and the second flange 340. The second flange 340 slides along the first flange 181, and the snap-in portion 330 on the first bottom panel 310 snaps into the corresponding socket 190. After the first bottom panel 310 is pushed toward the partition portion 200, the plug-in portion 311 on the first bottom panel 310 is inserted into the first slot 210 on the partition portion 200. At this time, the connecting flange 370 on the right side of the first bottom panel 310 is in contact with the right side wall of the casing body 100. By screwing screws between the two, the four sides of the first bottom panel 310 can be fully fixed.

[0110] When installing the second bottom panel 320, the second bottom panel 320 is pushed along the bottom opening of the second installation cavity 132 toward the direction close to the partition portion 200, and relative sliding occurs between the first flange 181 and the second flange 340. The second flange 340 slides along the first flange 181, and the snap-on portion 330 on the second bottom panel 320 snaps into the corresponding socket 190. After the second bottom panel 320 is pushed into place toward the partition portion 200, the second slot 321 on the second bottom panel 320 is plugged into the wall of the first slot 210 on the partition portion 200. At this time, the connecting flange 370 on the left side of the second bottom panel 320 is in contact with the left side wall of the casing body 100. Screws are screwed between the two to achieve full fixation of the four sides of the second bottom panel 320.

[0111] In some embodiments of the present application, refer to Fig.16 A fourth flange 360 ​​is provided on the second flange 340, and the fourth flange 360 ​​extends vertically toward one side of the casing body 100. The fourth flange 360 ​​is used to limit the horizontal displacement of the first flange 181 when the first flange 181 and the second flange 340 slide relative to each other.

[0112] That is to say, when the two bottom panels are installed and pushed toward the partition portion 200 , the fourth flange 360 ​​acts as a slide and a limiter.

[0113] In some embodiments of the present application, continue to refer to Fig.16The first flange 181 is provided with a fifth flange 182 extending vertically, and the socket 190 is an L-shaped opening structure provided on the first flange 181 and the fifth flange 182. Fig.11 The socket is large, so that when the bottom panel is lowered from top to bottom onto the casing body 100 , the clamping portion 330 can fall into the socket 190 .

[0114] A slot structure for installing the insulation layer is formed between the fifth flange 182 and the side wall of the housing body 100, which facilitates the installation of the insulation layer. At the same time, the bottom of the front / rear side wall of the housing body 100 forms two bending structures through the first flange 181 and the fifth flange 182, which helps to improve the structural strength.

[0115] In some embodiments of the present application, refer to Figure 7 and Fig.14 The plug-in portion 311 includes a plug-in vertical portion 3111, a plug-in horizontal portion 3112, and a plug-in inclined portion 3113 which are connected in sequence. The plug-in vertical portion 3111 vertically extends from the first bottom panel 310 toward one side of the installation cavity, the plug-in horizontal portion 3112 extends horizontally toward the outer side of the first bottom panel 310, and the plug-in inclined portion 3113 extends from the plug-in horizontal portion 3112 toward a direction away from the first bottom panel 310 and toward the outer side of the first bottom panel 310. The plug-in horizontal portion 3112 and the plug-in inclined portion 3113 are inserted into the first slot 210.

[0116] When installing the first bottom panel 310, after the first panel 310 is pushed in the direction close to the partition part 200, the plug-in horizontal portion 3112 and the plug-in inclined portion 3113 can be inserted into the first slot 210. The plug-in inclined portion 3113 serves as an installation guide, and the plug-in vertical portion 3111 abuts against one end of the first slot 210. Fig.14 The figure shows the placement posture during the assembly process. When the fresh air environment control integrated machine is actually used, Fig.14 By rotating 180°, it can be found that the plug-in transverse portion 3112 is in contact with the bottom wall of the first slot 210 to form a limit clamping structure in the up-and-down direction.

[0117] In some embodiments of the present application, refer to Fig.12 and Fig.14The first slot 210 includes a first slot transverse portion I211, a first slot vertical portion 212, and a first slot transverse portion II213 which are connected in sequence. The first slot vertical portion 212 is connected between the first slot transverse portion I211 and the first slot transverse portion II213. The first slot transverse portion I211 extends horizontally from the bottom of the partition portion 200 toward the direction of the second installation cavity 132. The first slot vertical portion 212 extends vertically from the first slot transverse portion I211. The first slot transverse portion II213 extends from the first slot vertical portion 212 toward one side of the first installation cavity 131. The first slot 210 is a U-shaped slot structure, and the plug-in transverse portion 3112 is in close contact with the first slot transverse portion II213.

[0118] Reference Fig.10 and Fig.14 The second bottom panel 320 is provided with a sixth flange 322 on the side facing the partition portion 200, and the sixth flange 322 extends vertically from the second bottom panel 320 toward the side of the installation cavity. The second slot 321 is connected to the sixth flange 322, and the sixth flange 322 is in contact with the plug-in vertical portion 3111, so that there is no gap between the first bottom panel 310 and the second bottom panel 320 after they are assembled.

[0119] In some embodiments of the present application, continue to refer to Fig.10 and Fig.14 The second slot 321 includes a second slot transverse portion I3211, a second slot vertical portion 3212, and a second slot transverse portion II3213. The second slot vertical portion 3212 is connected between the second slot transverse portion I3211 and the second slot transverse portion II3213. The second slot transverse portion II3213 extends horizontally from the sixth flange 322 toward one side of the second installation cavity 132. The second slot transverse portion I3211 extends horizontally from the second slot vertical portion 3212 toward the first installation cavity 131. The second slot 321 is a U-shaped slot structure, and the socket of the second slot 321 faces the first installation cavity 131.

[0120] The second slot 321 also includes a second slot inclined portion 3214, which extends obliquely from the second slot lateral portion I 3211 toward a direction away from the second bottom panel 320 and toward the outer side of the second bottom panel 20 (i.e., toward the first installation cavity 131). The second slot inclined portion 3214 serves as an installation guide during the assembly process of inserting the first slot 210 into the second slot 321.

[0121] The present invention not only solves the problem of independent disassembly and assembly of two bottom panels, but also solves the technical problem that internal components of the fresh air environment control integrated machine are inconvenient to install.

[0122] In the prior art, in order to improve the thermal insulation performance of the whole machine, an insulation layer is usually provided on the inner side of the casing. During the production and assembly of the whole machine, due to the presence of the insulation layer, when the components are installed into the casing by screws, the screws need to pass through the thick insulation layer to be fixed and installed. The screws are exposed, and the fixation is unreliable. Condensation water is easily generated at the exposed screws. In order to avoid the exposure of the nail tip, some models need to screw from the outside of the casing to the inside. At this time, there is also the problem of condensation water generated at the screws, and it is not convenient to align the screw holes of each component for screwing, resulting in low production efficiency. In addition, most existing casings are single-layer plate structures with low strength.

[0123] The present application solves the problem mentioned in the above paragraph by the following technical means: In some embodiments of the present application, referring to Figure 20 to Figure 24 The housing body 100 includes an upper cover plate 110 , two side plates 120 arranged opposite to each other on the left and right, and an inner cover plate 140 .

[0124] The upper cover plate 110 is a U-shaped structure, which includes an upper cover top plate 111, an upper cover front side plate 112, and an upper cover rear side plate 113 formed by bending a sheet of plate. The upper cover top plate 111 constitutes the top wall of the casing body 100, the upper cover front side plate 112 constitutes the front side wall of the casing body 100, and the upper cover rear side plate 113 constitutes the rear side wall of the casing body 100.

[0125] The two side panels 120 are disposed on the left and right sides of the upper cover 110 to form the left and right walls of the housing body 100 .

[0126] When the whole machine is assembled, the upper cover plate 110 and the left and right side plates 120 are first assembled together to form an installation frame structure, and the upper cover top plate 111 is placed downward, and then the internal partitions, fans, heat exchangers, heat exchange cores and other components are installed in the upper cover top plate 111, and finally the first bottom panel 310 and the second bottom panel 320 are installed. In order to improve the installation convenience and reliability of various internal components, the present application makes the following improvements to the upper cover plate 110: an inner cover plate 140 is arranged on the inner side of the upper cover top plate 111, and a accommodating space is enclosed between the inner cover plate 140 and the upper cover top plate 111, and an insulation layer is arranged in the accommodating space, which is recorded as the insulation layer 160, and a plurality of screw mounting holes are arranged on the inner cover plate 140.

[0127] A double-layer structure is formed between the upper cover top plate 111 and the inner cover plate 140. During assembly, the internal components are directly screwed to the inner cover plate 140, and the screws are screwed from the inside to the outside of the casing body 100. The screws are screwed and installed from the front, which greatly improves the ease of installation and efficiency. The screws are not exposed, which improves the aesthetics of the whole machine and avoids condensation at the exposed screws. The double-layer cover plate structure helps to improve the strength of the casing, and the thermal insulation layer in the double-layer structure also improves the thermal insulation performance of the casing.

[0128] In some embodiments of the present application, refer to Fig.21 and Fig. 22 A support portion 150 is provided in the accommodating space, one side of the support portion 150 is fixedly connected to the upper cover top plate 111 by screws, and the other side of the support portion 150 is fixedly connected to the inner cover plate 140 by screws.

[0129] Since the overall area of ​​the inner cover plate 140 is relatively large, the support portion 150 supports the inner cover plate 140 , thereby improving the installation stability of the inner cover plate 140 and preventing the middle area of ​​the inner cover plate 140 from collapsing.

[0130] In some embodiments of the present application, the support portion 150 extends along the length or width direction of the upper cover top plate 111. The support portion 150 divides the accommodating space into multiple sub-areas. An insulation layer is arranged in each sub-area, which improves the installation stability of the inner cover plate 140 and also facilitates the installation of the insulation layer.

[0131] Fig.21 In the structure shown, one support portion 150 is provided, and the support portion 150 extends along the length direction of the upper cover top plate 111 .

[0132] In some embodiments of the present application, refer to Fig.24 The support portion 150 includes an integral U-shaped groove 151 and a groove flange 152 provided at the open top edge of the U-shaped groove 151, the groove flange 152 extends toward the outside of the U-shaped groove 151, the groove bottom of the U-shaped groove 151 is fixedly connected to the upper cover top plate 111 by screws, and the groove flange 152 is fixedly connected to the inner cover plate 140 by screws.

[0133] Reference Fig.21 The U-shaped groove 151 divides the accommodating space into a first sub-area 171 and second sub-areas 172 located on both sides of the first sub-area 171. The first sub-area 171 is the notch area surrounded by the U-shaped groove 151 itself. The insulation layer 160 is arranged in the first sub-area 171 and the two second sub-areas 172, and the notch flange 152 is in contact with the insulation layer 160 located in the second sub-area 172.

[0134] The notch flange 152 facilitates the fixed connection between the support portion 150 and the inner cover plate 140 on the one hand, and serves to limit the built-in thermal insulation layer on the other hand.

[0135] The insulation layer 160 in the accommodation space does not need to be glued. During assembly, the glue-free insulation layer 160 can be directly placed in the first sub-area 171 and the second sub-area 172. At this time, the groove flange 152 plays a limiting role on the insulation layer in the two second sub-areas 172, and then the inner cover plate 140 is installed. The insulation layer 160 is finally limited in the accommodation space through the inner cover plate 140. The setting of the glue-free insulation layer also further improves the installation efficiency.

[0136] In some embodiments of the present application, refer to Fig.24 An extension plug 153 is provided on the groove wall at one end of the U-shaped groove 151, and a socket (not marked) is correspondingly provided on the inner cover plate 140. The extension plug 153 is inserted into the socket. When installing the support part 150, the extension plug 153 is first inserted into the socket to preliminarily position the support part 150, and then the support part 150 is fixed by screws for easy installation.

[0137] In some embodiments of the present application, refer to Fig.23 The inner cover flange 141 is provided on the four sides of the inner cover plate 140, and the inner cover flange 141 extends toward one side of the upper cover top plate 111, that is, the inner cover flange 141 extends upward, and the inner cover flange 141 abuts against the upper cover top plate 111. The inner cover flange 141 is fixedly connected to the circumferential side wall of the casing 100 by screws to realize the fixed installation of the inner cover plate 140, and screws are screwed on the circumferential outer side for easy installation.

[0138] In some embodiments of the present application, refer to Fig. 20 The inner cover plate 140 is provided with a handle 142 , and the handles 142 have two handles 142 symmetrically arranged on both sides of the inner cover plate 140 , and the handles 142 are convenient for holding the inner cover plate 140 for transportation and installation.

[0139] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0140] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
