Some embodiments of the present disclosure provide an air conditioner.

As shown in FIG. 1, the air conditioner 1000 includes an indoor unit 10 and an outdoor unit 20. The indoor unit 10 and the outdoor unit 20 are connected via a pipe to transmit the refrigerant. The indoor unit 10 includes an indoor heat exchanger 400 and an indoor fan 600. The outdoor unit 20 includes a compressor 201, a four-way valve 202, an outdoor heat exchanger 203, an outdoor fan 204, and an expansion valve 205. The compressor 201, the outdoor heat exchanger 203, the expansion valve 205, and the indoor heat exchanger 400 connected in sequence form a refrigerant circuit, and the refrigerant circulates through the refrigerant circuit and exchanges heat with the air through the outdoor heat exchanger 203 and the indoor heat exchanger 400, respectively, thereby realizing the cooling mode or the heating mode of the air conditioner 1000.

The compressor 201 is configured to compress the refrigerant so that the low pressure refrigerant is compressed to form a high pressure refrigerant.

The outdoor heat exchanger 203 is configured to exchange heat between the outdoor air and the refrigerant transmitted into the outdoor heat exchanger 203. For example, the outdoor heat exchanger 203 operates as a condenser in the cooling mode of the air conditioner 1000 so that the refrigerant compressed by the compressor 201 releases heat to the outdoor air through the outdoor heat exchanger 203 and condenses. The outdoor heat exchanger 203 operates as an evaporator in the heating mode of the air conditioner 1000 so that the refrigerant after decompression absorbs heat from the outdoor air through the outdoor heat exchanger 203 and evaporates.

In some embodiments, the outdoor heat exchanger 203 further includes heat exchange fins, which increase the contact area between the outdoor air and the refrigerant transmitted into the outdoor heat exchanger 203, thereby increasing the efficiency of heat exchange between the outdoor air and the refrigerant.

The outdoor fan 204 is configured to draw outdoor air into the outdoor unit 20 through the outdoor intake port of the outdoor unit 20 and to send out the outdoor air that has exchanged heat with the outdoor heat exchanger 203 through the outdoor air outlet port of the outdoor unit 20. The outdoor fan 204 supplies power to the flow of outdoor air.

The expansion valve 205 is connected between the outdoor heat exchanger 203 and the indoor heat exchanger 400, and the pressure of the refrigerant flowing between the outdoor heat exchanger 203 and the indoor heat exchanger 400 is adjusted by the opening degree of the expansion valve 205, thereby adjusting the flow rate of the refrigerant flowing between the outdoor heat exchanger 203 and the indoor heat exchanger 400. The flow rate and pressure of the refrigerant flowing between the outdoor heat exchanger 203 and the indoor heat exchanger 400 affect the heat exchange performance of the outdoor heat exchanger 203 and the indoor heat exchanger 400. The expansion valve 205 may be an electronic valve. The opening degree of the expansion valve 205 is adjustable to control the flow rate and pressure of the refrigerant flowing through the expansion valve 205.

The four-way valve 202 is connected in the refrigerant circuit, and is configured to switch the flow of refrigerant in the refrigerant circuit to cause the air conditioner 1000 to operate in cooling mode or heating mode.

The indoor heat exchanger 400 is configured to exchange heat between the indoor air and the refrigerant transferred into the indoor heat exchanger 400. For example, the indoor heat exchanger 400 operates as an evaporator in the cooling mode of the air conditioner 1000 so that the refrigerant that has been radiated heat through the outdoor heat exchanger 203 absorbs heat from the indoor air through the indoor heat exchanger 400 and evaporates. The indoor heat exchanger 400 operates as a condenser in the heating mode of the air conditioner 1000 so that the refrigerant that has absorbed heat through the outdoor heat exchanger 203 releases heat to the indoor air through the indoor heat exchanger 400 and condenses.

In some embodiments, the indoor heat exchanger 400 further includes heat exchange fins, which increase the contact area between the indoor air and the refrigerant transmitted into the indoor heat exchanger 400 and improve the heat exchange efficiency between the indoor air and the refrigerant.

The indoor fan 600 is configured to draw indoor air into the indoor unit 10 through the indoor air intake port of the indoor unit 10 and to send out the indoor air that has exchanged heat with the indoor heat exchanger 400 through the indoor air outlet port of the indoor unit 10. The indoor fan 600 supplies power to the flow of indoor air.

Normally, a circuit board for integrating electrical control elements is installed in the indoor unit, and in order to protect the circuit board from erosion by water vapor and collisions, the circuit board is generally enclosed in an electrical control box to play a protective role. In addition, to ensure electrical insulation between the circuit board and the electrical control box, the electrical control box is generally made of plastic material. However, the fire resistance of plastic electrical control boxes is poor, and after the circuit board shorts out and catches fire, the plastic electrical control box will be burned and deformed by the direct flame, and the flames will spread from the plastic electrical control box to the inside of the indoor unit, burning other elements of the indoor unit and even causing a fire.

To improve the fire resistance of the electric control box, the electric control box may be enclosed in a fire-prevention housing. The housing has stronger fire resistance to prevent further spread of flames. However, since the circuit board needs to be connected to other elements of the indoor unit via conductors, the housing needs to have multiple outlets for the conductors to pass through. This makes it easier for flames to escape from the outlets after the circuit board ignites, reducing the fire-prevention effect of the housing.

In order to solve the above problems, some embodiments of the present disclosure provide an air conditioner. As shown in FIG. 2 to FIG. 6, the indoor unit 10 further includes a housing 1, an electric control box 2, and a circuit board 3. The housing 1 includes a box body 11 and a cover body 12. The box body 11 includes a box body main body 117 and a first mounting groove 111. The first mounting groove 111 is provided on one side of the housing body 117. The cover body 12 includes a cover body main body 128 and a second mounting groove 121. The second mounting groove 121 is provided on one side of the cover body main body 128. The cover body body 128 is placed on the box body 117 such that the first mounting groove 111 and the second mounting groove 121 together form a mounting cavity. The cover 12 further includes a first outlet 122, which is provided on one side (e.g., the upper side) of the cover body 128, and the first outlet 122 communicates with the second mounting groove 121. The box 11 further includes a baffle plate 112, which is provided on a side (e.g., the upper side) of the first mounting groove 111 closer to the first outlet 122. The baffle plate 112 is inserted into the second mounting groove 121 to shield the first outlet 122 and has a preset distance between it and the upper wall of the second mounting groove 121 to form an outlet gap. The electric control box 2 is provided in the mounting cavity. The circuit board 3 is mounted in the electric control box 2.

The baffle plate 112 is inserted into the second mounting groove 121, shielding the first outlet 122, and forms an outlet gap between the upper wall of the second mounting groove 121 so that the conductor first bypasses the baffle plate 112 and then passes through the outlet gap and the first outlet 122. After the electric control box 2 ignites, the baffle plate 112 effectively blocks the leakage of flames from the first outlet 122, preventing the flames from leaking outside the housing 1 and enhancing the fireproofing effect of the housing 1, thereby protecting the internal elements of the indoor unit 10 from being burned.

In some embodiments, the cover 12 further includes a second outlet 123 provided on one side (e.g., the front side) of the cover body 128 and a third outlet 124 provided on one side (e.g., the front side) of the cover body 128, and the second outlet 123 and the third outlet 124 communicate with the second mounting groove 121. The second outlet 123 and the third outlet 124 are provided at intervals along the longitudinal direction (e.g., the vertical direction) of the cover body 128, providing a wire passage space for passing other conductors inside the housing 1. The second outlet 123 and the third outlet 124 are opened on the front side of the cover 12, thereby effectively preventing flames from leaking from above and enhancing the fireproofing effect of the housing 1.

In some embodiments, the box 11 further includes a plurality of first protrusions 113, which are arranged on opposite sides (e.g., the front and rear sides) of the box body 117. The lid 12 further includes a plurality of fixing holes 125, which are arranged on opposite sides of the lid body 128 and correspond to the positions of the plurality of first protrusions 113. The plurality of first protrusions 113 are drilled into the plurality of fixing holes 125, which are fitted into and fixed to the plurality of first protrusions 113. When the box 11 is attached to the lid 12, the first protrusions 113 are fitted into the fixing holes 125, and the connection between the lid 12 and the lid 11 is strengthened.

In some embodiments, the box 11 further includes a plurality of first snaps 114, which are disposed on opposite sides (e.g., the front or rear) of the box body 117. The cover 12 further includes a plurality of first engagement holes 126 that engage with the plurality of first snaps 114, which are disposed on opposite sides of the cover body 128. The first snaps 114 are located at the rear top of the box body 117, and the first engagement holes 126 are also located at the rear top of the box body 128. After the box 11 is attached to the cover 12, the first snaps 114 and the first engagement holes 126 engage with each other to achieve a stable connection. The first snap 114 is an elastic paddle, and there is a predetermined distance (e.g., 4 mm) between the elastic paddle and the rear side of the box body 11. By pressing the elastic paddle, the engagement between the first snap 114 and the first engagement hole 126 can be released, thereby realizing removal between the box body 11 and the lid body 12, which makes it easy to remove and facilitates later maintenance.

In some embodiments, the box 11 further includes a plurality of elastic stopper pieces 115, which are located on two opposing side walls (e.g., both front and rear side walls) of the first mounting groove 111. After the box 11 is attached to the lid 12, the elastic stopper pieces 115 on both the front and rear sides of the lid 12 abut against the front and rear sides of the lid 12, respectively, to prevent the front and rear sides of the lid 12 from opening outward, thereby enhancing the fireproofing effect of the lid 1.

In some embodiments, the indoor unit 10 further includes a base 4, and one end (e.g., the lower end) of the box 11 is inserted into the base 4 and is adjacent to one side of the base 4, for example, the box 11 is adjacent to the right side of the base 4, thereby reducing the space occupied by the indoor unit 10 in the housing 1 and further improving the space utilization rate of the indoor unit 10. The lid 12 is provided on one side (e.g., the upper side) of the base 4.

The housing 1 further includes a plate body 5, which is provided over the first mounting groove 111 and is located on one side (e.g., the lower side) of the first mounting groove 111. The plate body 5 includes a plate body main body 53 and a plurality of folding parts 51. The plurality of folding parts 51 are arranged on opposite sides (e.g., the front and rear sides) of the plate body main body 53, and the plane on which the plurality of folding parts 51 are located is approximately perpendicular to the plate body main body 53. Each folding part 51 includes a second engagement hole 511, and the box body 11 further includes a plurality of second snaps 116, which are arranged on opposite sides (e.g., the front and rear sides) close to the lower side of the box body 117 and engage with the second engagement holes 511. After the plate body 5 is attached to the box body 11, the second snap 116 engages with the second engagement hole 511, realizing a stable connection, making the plate body 5 and the box body 11 easily removable, and facilitating later maintenance.

In some embodiments, the plate 5 further includes a first insertion groove 52, which is disposed on one side (e.g., the upper side) of the plate body 53. The cover 12 further includes a first insertion block 127, which is disposed on one side (the lower side) of the cover body 128 and is inserted into the first insertion groove 52. Before the plate 5 is attached to the box 11, the first insertion block 127 is first inserted into the first insertion groove 52 to integrally connect the lid 12 and the plate 5, and then the lid 12 and the plate 5 are fitted together from front to back into the box 11, engaging the first snap 114 with the first engagement hole 126 and the second snap 116 with the second engagement hole 511, thereby realizing the attachment of the lid 12, the plate 5, and the box 11, with high attachment efficiency and improved internal sealing of the housing 1.

The first snap 114 and the second snap 116 have an inclined guide surface and a vertical abutment surface, and after the guide surface smoothly slides through the engagement hole, the abutment surface abuts against the engagement hole to make it difficult for the engagement hole to slide in the reverse direction.

As shown in Figures 2, 7 to 10, the electric control box 2 includes an electric control box body 28, a third mounting groove 21, a plurality of deformation holes 22, a plurality of elastic pieces 23, a plurality of third snaps 24, and a plurality of abutment portions 25, the third mounting groove 21 is arranged on one side (e.g., the right side) of the electric control box body 28, the plurality of deformation holes 22 are arranged on opposite sides (e.g., the front and rear sides) of the third mounting groove 21, the plurality of deformation holes 22 are connected to the third mounting groove 21, the plurality of elastic pieces 23 are arranged on opposite sides (e.g., the front and rear sides) of the third mounting groove 21, the plurality of third snaps 24 are arranged at the ends of each elastic piece 23 close to the bottom of the third mounting groove 21, and the third snaps 24 may be placed outside the electric control box body 28 through the deformation holes 22. The circuit board 3 is placed at the bottom of the third mounting groove 21, and the third snaps 24 on the two elastic pieces 23 are engaged with both opposing sides (e.g., the front and rear sides) of the circuit board 3. The abutment portion 25 is placed on one side of the third snap 24, and at least a portion of the abutment portion 25 is located outside the circuit board 3.

When the circuit board 3 is pulled out of the third mounting groove 21, the circuit board 3 pulls and deforms the elastic pieces 23 on both the front and rear sides, bringing them closer together. At this time, the abutment portion 25 on the third snap 24 abuts against the side wall of the circuit board 3, and the two abutment portions 25 abut against the front and rear sides of the circuit board 3, respectively, restricting further deformation of the elastic pieces 23 and further restricting the circuit board 3 from being pulled out. This protects the elastic pieces 23 and the third snap 24 and prevents the elastic pieces 23 from breaking when the circuit board 3 is forcibly and erroneously removed.

10, the third snap 24 includes a first guide surface 241 and a first abutment surface 242 connected to each other, the first guide surface 241 is inclined, and the first abutment surface 242 is horizontal. The first abutment surface 242 is located between the bottom of the third mounting groove 21 and the first guide surface 241, the first abutment surface 242 abuts against the right side surface of the circuit board 3, and the abutment portion 25 is provided on the first abutment surface 242. When the circuit board 3 is inserted into the third mounting groove 21 from right to left, the front and rear sides of the circuit board 3 come into contact with the first guide surfaces 241 of the third snaps 24 on both sides, and the third snaps 24 move the elastic pieces to deform outward in the deformation holes 22. After the circuit board 3 slides along the first guide surfaces 241, the first contact surface 242 comes into contact with the right side surface of the circuit board 3, restricting the movement of the circuit board 3 to the right, thereby allowing the circuit board 3 to be engaged with the bottom of the third mounting groove 21.

In some embodiments, the extension direction of the abutment portion 25 is a straight line. In this way, the abutment portion 25 increases the contact area with the circuit board 3 to enhance the effect of preventing the abutment portion 25 from being erroneously removed from the circuit board 3. Of course, the extension direction of the abutment portion 25 may be an arc or a curve.

The two elastic pieces 23 are respectively provided adjacent to the upper side of the electric control box 2, and the electric control box 2 further includes a second insertion groove 26, which is provided on one side (e.g., the lower side) of the third mounting groove 21. The circuit board 3 includes a circuit board body 32 and a second insertion block 31, which is provided on one side (e.g., the lower side) of the circuit board body 32 and is inserted into the second insertion groove 26. In the process of mounting the circuit board 3 in the third mounting groove 21, the second insertion block 31 is first inserted into the second insertion groove 26, and then the upper side of the circuit board 3 rotates around the lower side of the electric control box 2, and the third snap 24 is engaged with the upper end of the right side of the circuit board 3, thereby stabilizing the circuit board 3 at the bottom of the third mounting groove 21 and improving the connection stability.

In some embodiments, the electrical control box 2 is integrally molded with the elastic piece 23, which provides greater overall structural strength and is advantageous in stabilizing the circuit board 3 at the bottom of the third mounting groove 21.

The electric control box 2 is attached to the first mounting groove 111, the opening of the third mounting groove 21 faces the cover body 12, and the electric control box 2 further includes a plurality of locking portions 27, which are arranged on opposite sides (e.g., the front and rear sides) of the electric control box body 28, and which lock onto the side walls of the second mounting groove 121. The electric control box 2 is fixed to the mounting cavity via the plurality of locking portions 27 to prevent displacement of the electric control box 2 during use.

As shown in Figures 11 to 15, the indoor unit 10 further includes a sleeve 6. The sleeve 6 is provided on one side of the base 4 and is hollow. The hollow portion of the sleeve 6 forms a cavity. Both ends of the sleeve 6 (e.g., the upper and lower ends) are open, which are a first opening 621 and a second opening 622, respectively, and the first opening 621 and the second opening 622 communicate with the cavity. The first opening 621 is provided on the side of the sleeve 6 that is away from the base 4, and is formed, for example, at the upper end of the sleeve 6. The first opening 621 communicates with the cavity. The electric wires of the indoor unit 10 are drilled into the sleeve 6.

When the electric wire is passed through the lower end of the sleeve 6, the lower end of the sleeve 6 effectively restrains the electric wire, restricting it from escaping, and also preventing the electric wire from contacting the cover of the indoor unit 10 when performing an electric wire tensile test. When the electric wire is passed through the upper end of the sleeve 6, the first opening 621 provides a space for the electric wire to pass through, and the first opening 621 can reduce the material cost of the sleeve 6.

In some embodiments, the sleeve 6 includes a first side plate 61, a second side plate 62, a third side plate 63, and a fourth side plate 64 that are parallel to each other, the front side of the first side plate 61 and the front side of the second side plate 62 are connected via the third side plate 63, the rear side of the first side plate 61 and the rear side of the second side plate 62 are connected via the fourth side plate 64, and the first side plate 61, the second side plate 62, the third side plate 63, and the fourth side plate 64 surround the cavity to form a wire passage cavity. The first side plate 61 is adjacent to the base 4, and the first opening 621 opens to the second side plate 62. For example, the first side plate 61 is attached to one side of the base 4 to increase space utilization.

In some embodiments, the front and rear sides of the first opening 621 penetrate the third side plate 63 and the fourth side plate 64, respectively, thereby increasing the area of the first opening 621, thereby increasing the space for passing the electric wires and making the wire passing operation easier.

In some embodiments, the base 4 includes a base body 43 and a first guide post 41, the first guide post 41 is disposed on one side of the base body 43, the first side plate 61 includes a first guide hole 611, and the first guide post 41 is drilled into the first guide hole 611. During the process of mounting the sleeve 6 to the base 4, the sleeve 6 is drilled into the first guide hole 611 via the first guide post 41, thereby fulfilling a positioning role.

In some embodiments, as shown in FIG. 13, one side of the base body 43 has an engagement hole, and the first side plate 61 includes a fourth snap 612 that engages with the engagement hole. The fourth snap 612 has elasticity. The fourth snap 612 engages with the engagement hole so that the sleeve 6 is fixed to one side of the base 4, and plays a role in positioning and fixing, and improves the convenience and accuracy of the installation of the sleeve 6.

In some embodiments, one side of the base body 43 has a guide groove, and the first side plate 61 includes a guide rib 613 that is slidably connected to the guide groove. During the process of mounting the sleeve 6 to the base 4, the mounting position of the sleeve 6 and the base 4 is further determined by the sliding connection between the guide rib 613 and the guide groove.

The first side plate 61 has a flat surface, and the third side plate 63 and the fourth side plate 64 have arc surfaces. The first side plate 61, which has a flat surface, can be well attached to the side wall of the base 4, reducing the gap between the sleeve 6 and the base 4 and increasing the space utilization rate inside the indoor unit 10. The third side plate 63 and the fourth side plate 64, which have arc surfaces, are designed based on the structural compatibility of the internal assembly of the indoor unit 10.

The sleeve 6 further includes an extension 65, which is connected to a sidewall of the first opening 621 and has a mounting hole 651 for mounting a screw fastener, and the center line of the mounting hole 651 extends along the longitudinal direction (e.g., the upward and downward directions) of the sleeve 6. As shown in Fig. 11, the extension 65 is a bent plate material.

16 to 29, the indoor unit 10 further includes a cover 7, a bracket 8, and a display assembly 9. The base 4 is provided in the cover 7 and includes a mounting frame 42, which is provided on one side of the base body 43. The plane on which the mounting frame 42 is located is approximately perpendicular to the longitudinal direction of the cover 7. The bracket 8 is provided on the mounting frame 42, which includes a bracket body 86, a first engagement hook 81, a second engagement hook 82, and a second guide hole 83, which are provided on the bracket body 86.

The pressing rib 71 may be plate-shaped or block-shaped, and the pressing rib 71 can be provided by abutting against the upper side of the connection portion 811 and attaching the connection portion 811 to the surface of the mounting frame 42, thereby preventing separation between the hook portion 812 and the first engagement groove 421, thereby firmly fixing the display assembly 9 to the mounting frame 42 and increasing the mounting stability of the display assembly 9 in the cover 7.

24 to 28, the hook portion 812 includes a second guide surface 8121 and a second abutment surface 8122, where the second guide surface 8121 is provided at an incline and the second abutment surface 8122 is provided vertically. The second guide surface 8121 abuts against the upper side of the mounting bracket 42, and is used to guide the attachment of the bracket 8 to the mounting bracket 42. The second abutment surface 8122 abuts against the side wall of the first engagement groove 421 so that the hook portion 812 engages with the first card groove 421. When the bracket 8 is attached to the mounting frame 42, the bracket 8 moves forward relative to the mounting frame 42, and the second guide surface 8121 may slide along the surface of the mounting frame 42 before being placed in the first engagement groove 421. At this time, the second abutment surface 8122 is also placed in the first engagement groove 421, and the second abutment surface 8122 abuts against the side wall of the first engagement groove 421 to restrict the rearward movement of the bracket 8, and the first engagement hook 81 is engaged in the first engagement groove 421, so that the bracket 8 can be stably attached to the mounting frame 42. The configuration of the second engagement hook 82 is similar to that of the first engagement hook 81, and will not be described further here.

In some embodiments, as shown in Figs. 24 to 27, the bracket 8 further includes a mounting plate 84, which is provided on one side of the bracket body 86 and is used to fix the display assembly 9. The first engagement hook 81, the second engagement hook 82, and the second guide post 422 are provided on one side (e.g., the rear side) of the mounting plate 84. The display assembly 9 is attached to the mounting frame 42 by being integrally connected to the bracket 8 by fixing the display assembly 9 to the mounting plate 84 using a bolt connection, adhesive, or snap connection, and the display assembly 9 can be removed by removing the bracket 8 and the mounting frame 42, which is simple to operate and can avoid damage to the display assembly 9.

The mounting plate 84 includes a mounting plate body 844, a plurality of support parts 841, and a fourth mounting groove 842. The plurality of (e.g., two) support parts 841 are provided on both opposing sides (e.g., both upper and lower sides) of the front side of the mounting plate body 844. The fourth mounting groove 842 is located on one side of the mounting plate body 844. The two support parts 841 and the front side of the mounting plate body 844 surround each other to form the fourth mounting groove 842, and the display assembly 9 is fitted into the fourth mounting groove 842. The surface of the display assembly 9 is covered by the support parts 841, thereby preventing the display assembly 9 from colliding with the cover 7, and the two support parts 841 clamp the display assembly 9 to each other, firmly fixing the display assembly 9 to the mounting frame 42.

24, 25, 27 and 29, the support portion 841 has a plurality of second engagement grooves 843, for example, the support portion 841 has two second engagement grooves 843. The display assembly 9 includes a display assembly body 92 and a plurality of second protrusions 91, and the plurality of (for example, two) second protrusions 91 are arranged on opposite sides (for example, both upper and lower sides) of the display assembly body 92, and the two second protrusions 91 are engaged with the two second engagement grooves 843. When the display assembly 9 is attached to the bracket 8, the display assembly 9 is inserted into the fourth mounting groove 842 along a direction perpendicular to the groove bottom of the fourth mounting groove 842, and the two second protrusions 91 are respectively engaged with the two second engagement grooves 843 to engage the display assembly 9 in the fourth mounting groove 842, which makes it convenient to remove the display assembly 9 from the bracket 8 when performing maintenance on the display assembly 9.

In some embodiments, the bracket 8 further includes a limiting rib 85 provided on one side (e.g., the rear side) of the mounting plate 84, and the limiting rib 85 extends along the longitudinal direction of the cover 7. The mounting frame 42 has a limiting groove 423 that engages with the limiting rib 85. The limiting rib 85 engages with the limiting groove 423 to restrict movement of the bracket 8 on the mounting frame 42, and the first engagement hook 81 engages with the first engagement groove 421 to ensure that the second engagement hook 82 is engaged with one side of the mounting frame 42, thereby firmly fixing the bracket 8 to the mounting frame 42.

In some embodiments, the first engagement hook 81 and the second engagement hook 82 are elastic members, such as plastic members or elastic metal members, and when the bracket 8 is attached to the mounting bracket 42, the first engagement hook 81 and the second engagement hook 82 may be appropriately stretched and adjusted in position to ensure that the bracket 8 is smoothly attached to the mounting bracket 42. The bracket 8 is a plastic member and may be formed as a one-piece member by an injection molding process, which improves the structural strength of the entire bracket 8 and increases the service life of the bracket 8.
