Detailed Description

The present invention is specifically described below by way of exemplary embodiments. It should be understood, however, that elements, structures and features of one embodiment may be beneficially incorporated in other embodiments without further recitation.

Hereinafter, embodiments according to the present disclosure will be described in detail with reference to the accompanying drawings.

The air conditioner in the present disclosure 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, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

The compressor compresses a refrigerant gas in a high-temperature and high-pressure state 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 heat is released to the surrounding environment through the condensation process.

The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.

The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit of the air conditioner.

The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.

Fig. 1 is a perspective view of an air conditioning indoor unit according to an embodiment of the present disclosure. The air conditioning indoor unit has a substantially rectangular parallelepiped shape and is generally mounted on an upper portion of a wall of a house for use, and fig. 2 is a side view of the air conditioning indoor unit mounted on the wall.

For convenience of description, referring to mounting of the air-conditioning indoor unit on a wall, a side of the air-conditioning indoor unit adjacent to the wall is a rear side, a side opposite to the rear side is a front side, a side adjacent to the ground is a lower side, and a side opposite to the lower side is an upper side.

The air conditioning indoor unit according to the embodiment of the present disclosure includes a heat exchanger and an indoor fan (not shown), which are all built into the casing 1.

The casing 1 is substantially rectangular and forms a main framework of the air conditioning indoor unit.

Openings are provided in the housing 1 to form an air inlet 11 and an air outlet 12. An air inlet 11 is provided at an upper surface of the cabinet 1, and indoor air is introduced through the air inlet 11; the outlet 12 is disposed at a lower surface of the cabinet 1, and air introduced from the inlet 11 is heat-exchanged by the heat exchanger and discharged to an indoor space through the outlet 12.

Inside the cabinet 1, an air passage is formed from the intake port 11 to the outtake port 12, and a heat exchanger and an indoor fan are disposed on the air passage.

The filter screen is disposed between the air inlet 11 and the heat exchanger, and the filter screen can filter dust in the indoor air sucked from the air inlet 11.

The front side of the casing 1 is provided with a front panel 2, and the front panel 2 is rotatably connected to the casing 1.

Referring to fig. 3 and 4, the dotted arrow indicates the rotation direction of the front panel 2 when it is opened. When the front panel 2 rotates towards a direction far away from the indoor unit of the air conditioner, part of the filter screen can be exposed, so that the filter screen can be conveniently pulled out from the indoor unit of the air conditioner, cleaned or replaced and the like.

Or,

the air-conditioning indoor unit may further include a filter screen cleaning device (not shown) accommodated in the front surface of the casing 1 at the rear side of the front panel 2, and the filter screen cleaning device may be operated by opening the front panel 2 to be easily taken out of or attached to the air-conditioning indoor unit.

The front panel 2 may expose the front surface by allowing the lower portion of the front panel 2 to rotate upward. When the front panel 2 is closed to cover the front surface, the front side appearance of the air conditioning indoor unit is defined.

Referring to fig. 5 to 8, the front panel 2 is rotatably coupled to the cabinet 1 about a rotation shaft 211. A rotation arm 21 is projected from the upper portions of both left and right ends of the front panel 2 in the longitudinal direction, and a rotation shaft 211 is formed on the rotation arm 21. Accordingly, grooves 13 are formed at both left and right ends of the upper portion of the front surface of the cabinet 1, the rotating arms 21 are inserted into the grooves 13, and mounting holes 15 are formed on the inner walls of the grooves 13. In the assembled position, the rotating shaft 211 is mounted in the mounting hole 15.

A forward force is applied to the lower end of the front panel 2, and the lower end of the front panel 2 can rotate upward around the rotating shaft 211; when the front panel 2 is in the closed position, the rotating arm 21 is accommodated in the groove 13.

As shown in fig. 8, a support shaft 212 is further formed on the rotating arm 21, and the support shaft 212 is located at a lower side of the rotating shaft 211; during the rotation opening of the front panel 2, the support shaft 212 is rotated around the rotation shaft 211 by the front panel 2, forming a rotation path S of the support shaft 212.

A support base 14 is provided on the lower inner wall of the recess 13, a part of the support base 14 is located in the rotation path S, and a part of the support base 14 located in the rotation path S is defined as a barrier 140. Therefore, when the support shaft 212 rotates upward to touch the support table 14, the interference resistance between the support shaft 212 and the support table needs to be overcome by a small force, so that the support shaft 212 can continue to rotate and open over the obstacle 140; conversely, when the support shaft 212 is rotated downward, it is blocked by the blocking portion 140, and a slight force is required to continue the rotational closing of the support shaft 212 beyond the support table 14.

Based on the above structure, when the front panel 2 is opened until the support shaft 212 passes over the obstacle 140, the support shaft 212 may be blocked by the obstacle 140, so that the front panel 2 may not be easily closed without being subjected to an external force. Therefore, the front panel 2 can be maintained in the open state at the set angle by the cooperation of the obstacle portion 140 and the support shaft 212, and the operator can release both hands to perform other operations without holding the front panel 2 with hands to maintain the open state.

Referring to fig. 9, the support table 14 includes a first plane 143 and a second plane 144, the first plane 143 and the second plane 144 are connected at an included angle, and a convex corner is formed at the connection position of the first plane 143 and the second plane 144, and the convex corner is the barrier 140. Wherein the first plane 143 is near the bottom of the recess 13 and the second plane 144 is near the front side. When the front panel 2 is opened by rotation, the supporting shaft 212 rotates around the rotating shaft 211 to touch the first plane 143, the front panel 2 is rotated forcibly, the supporting shaft 212 can overcome the blocking at the convex angle on the first plane 143, and then the supporting shaft 212 rotates to pass through the convex angle to abut against the second plane 144, at this time, the force applied to the front panel 2 can be stopped, and because the blocking at the convex angle on the second plane 144, the supporting shaft 212 cannot overcome the resistance by the gravity of the supporting shaft 212, and the state is kept unchanged.

Because the supporting shaft 212 is cylindrical and the barrier part 140 is pointed, when the two parts move relatively, the friction area is small, the opening and closing times of the front panel 2 can be increased, and the convenient operation durability of the air conditioner indoor unit is ensured.

The first plane 143 and the second plane 144 are rounded, i.e. the obstacle 140 is arc-shaped, so that the supporting shaft 212 and the obstacle 140 have rolling friction therebetween, and the abrasion between the supporting shaft 212 and the supporting table 14 is further reduced.

When the support shaft 212 abuts against the second plane 144, the front panel 2 is in the open holding state, and thus the angle of the holding state of the front panel 2 can be determined by designing the positions of the support shaft 212 and the support table 14.

In order to ensure the support platform 14 stably supports the support shaft 212, the support platform 14 needs to have a certain width, but if the width is too large, the contact area between the support platform 14 and the support shaft 212 is increased, so that the wear area between the support shaft 212 and the support platform 14 is increased, which is not beneficial to the durability of the air conditioning indoor unit, therefore, as shown in fig. 6, the support platform 14 includes a first rib 141 and a second rib 142 which are parallel, and a gap is formed between the first rib 141 and the second rib 142, so that the support width of the support platform 14 to the support shaft 212 can be ensured, the contact area between the support platform 14 and the support shaft 212 can be reduced, and the wear between the support shaft 212 and the support platform 14 is further reduced.

The support table 14 is integrally formed on the housing 1 and is formed by extending the lower inner wall of the groove 13 upward, so that the processing and manufacturing are convenient and the cost is low.

Referring to fig. 6 and 11, the rotating arm 21 is in a non-closed curved shape, one end of the rotating arm 21 is connected to the inner surface of the front panel 2 and is a connecting end, the other end of the rotating arm 21 is a free end, the rotating shaft 211 is located at the free end and extends and protrudes perpendicular to the rotating arm 21, the axis of the rotating shaft 211 is parallel to the length direction of the front panel 2, when the front panel 2 is in an assembled and closed state, the free end is located above the connecting end, and the supporting shaft 212 is formed near the lowest point of the rotating arm 21.

The supporting shaft 212 and the rotating shaft 211 are located on one side of the rotating arm 21 close to the center of the front panel 2, and the axes of the supporting shaft and the rotating shaft are parallel, so that the structure is compact, the forming is convenient, and the volume of the groove 13 matched with the supporting shaft and the rotating shaft can be as small as possible.

The supporting shaft 212 has a forced friction with the barrier portion 140 during the rotation, and the outer diameter of the supporting shaft 212 is larger than that of the rotating shaft 211, so that the consistency of the overall strength is ensured.

When the front panel 2 is assembled, the rotating arm 21 of the front panel 2 is inserted into the groove 13 of the housing 1, and then the rotating shaft 211 is inserted into the mounting hole 15.

With continued reference to fig. 8, the mounting hole 15 is substantially "U" shaped, and includes a first sidewall 151, a second sidewall 152 and a bottom wall 153, the front side of the mounting hole 15 is open, the first sidewall 151 is provided with a protrusion 154 extending toward the second sidewall 152, and a distance D between the protrusion 154 and the other sidewall is smaller than the outer diameter of the rotating shaft 211.

The rear surface of the projection 154 is a curved surface located on the same circle as the bottom wall 153, and the front surface of the projection 154 is an inclined surface inclined to the rear side. The shaft 211 enters from the open end of the mounting hole 15 and enters into the circular hole formed by the bottom wall 153 and the curved surface from the distance D along the inclined surface. Because the distance D is smaller than the outer diameter of the rotating shaft 211, when the rotating shaft 211 passes through the distance D, the rotating shaft 211 needs to slightly force to overcome the resistance of the protrusion 154 to enter the circular hole, otherwise, the rotating shaft 211 cannot easily come out of the circular hole due to the blockage of the protrusion 154.

As shown in fig. 10 and 11, retaining pieces 23 for preventing detachment are formed at lower portions of left and right ends of the front panel 2, respectively, and receiving holes 16 for receiving the retaining pieces 23 are formed at left and right ends of a front lower portion of the cabinet 1; a bracket 161 is formed in the receiving hole 16, and when the holding piece 23 is inserted into the receiving hole 16, an end portion of the holding piece 23 is caught on the bracket 161, thereby allowing the front panel 2 to be attached to the cabinet 1.
