Detailed Description

The air conditioner of the present utility model performs a refrigerating 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 a 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-temperature and 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 may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner may adjust the temperature of the indoor space throughout the cycle.

The outdoor unit of the air conditioner refers to a portion of the refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes the indoor heat exchanger 4, and an expansion valve may be provided in the indoor unit or the outdoor unit.

The indoor heat exchanger 4 and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger 4 is used as a condenser, the outdoor heat exchanger is used as a heater for a heating mode, and when the outdoor heat exchanger is used as an evaporator, the indoor heat exchanger 4 is used as a cooler for a cooling mode.

Embodiments of the present utility model are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary, and a wall-mounted air conditioner 100 according to the embodiments of the present utility model is described below with reference to fig. 1 to 11.

As shown in fig. 1 to 11, a wall-mounted air conditioner 100 according to an embodiment of the present utility model includes a housing 1, a base 2, an indoor heat exchanger 4, a water pan 6, and a fan assembly 5.

Specifically, the housing 1 is formed with an air inlet 11 and an air outlet 12. The housing 1 is covered on the front side of the base 2 to form an accommodating space 21. The indoor heat exchanger 4 is provided in the accommodating space 21 for heat exchange with indoor air. The water receiving disc 6 is arranged below the indoor heat exchanger 4 and is used for receiving condensed water formed by the indoor heat exchanger 4 in the heat exchange process. The fan assembly 5 is disposed in the accommodating space 21, and is used for driving indoor air to enter the casing 1 through the air inlet 11, exchange heat with the indoor heat exchanger 4, and flow out from the air outlet 12. An air outlet channel 22 is formed on one side of the base 2 adjacent to the air outlet 12, the air outlet channel 22 comprises an air outlet upper wall 221 and an air outlet lower wall 222 spaced from the air outlet upper wall 221, a groove 3 is formed between the bottom wall of the water pan 6 and the air outlet upper wall 221, and at least one reinforcing rib 31 is arranged in the groove 3. Wherein, in the direction of height of the casing 1, the strengthening rib 31 is vertical to be set up, and the one end of strengthening rib 31 links to each other with the diapire of water collector 6, and the other end of strengthening rib 31 is spaced apart with air-out upper wall 221.

For example, in the example of fig. 1 to 11, the air inlet 11 and the air outlet 12 are formed at both sides of the housing 1 in the height direction (for example, the up-down direction of fig. 11), respectively, and the housing 1 and the base 2 are relatively covered to form the accommodation space 21. The indoor heat exchanger 4 can exchange heat to the air that gets into the casing 1, and water collector 6 is located the below of indoor heat exchanger 4, and water collector 6 and base 2 integrated into one piece, water collector 6 extend along the length direction of the inner wall of base 2. The water receiving tray 6 is used for receiving condensed water formed by heat exchange of air through the indoor heat exchanger 4 and discharging the condensed water to the outside through a drain pipe so as to prevent water leakage of the shell 1. The fan assembly 5 includes a fan and a motor driving the fan to rotate, and the fan assembly 5 and the indoor heat exchanger 4 are both fixed in the accommodating space 21. The air after heat exchange reaches the air outlet 12 through the air outlet channel 22, the air deflector 23 is rotatably arranged at the air outlet 12, and the air outlet 12 is opened or closed by the rotation of the air deflector 23. The recess 3 is formed at the upper side of the air outlet passage 22. The wall-mounted air conditioner 100 may be installed on a wall in a room. When the wall-mounted air conditioner 100 works, indoor air enters the shell 1 through the air inlet 11 by utilizing the rotation of the fan, then is changed into cooled or heated air after exchanging heat with the indoor heat exchanger 4, and flows into a room from the air outlet 12, so that the cooling or heating of the indoor air is realized.

Wherein the recess 3 extends in the longitudinal direction of the base 2 (e.g., the left-right direction in fig. 2). The reinforcing rib 31 extends in the depth direction (e.g., the left-right direction in fig. 3) of the groove 3, one end of the reinforcing rib 31 in the width direction (e.g., the up-down direction in fig. 3) is connected to the inner wall of the water tray 6, and the other end of the reinforcing rib 31 is spaced apart from the air outlet upper wall 221.

Since the base 2 is formed by injection molding with a mold, cooling is required after the casting is completed, and demolding is performed after the casting liquid becomes solid to obtain the base 2. In the prior art, the air outlet upper wall 221 is connected with the reinforcing rib 31, that is, the wall thickness of the connection part of the groove 3 and the reinforcing rib 31 is thicker, the thickness of the side wall of the base 2 adjacent to the air outlet 12 is uneven, so that the connection part is easy to shrink due to the larger wall thickness when the base 2 is cooled and solidified, that is, the side of the air outlet upper wall 221 far away from the reinforcing rib 31 is recessed, when the air deflector 23 rotates to a certain angle to open the air outlet 12, a user stands under the wall-mounted air conditioner 100, and can see the recess on the air outlet upper wall 221 from the air outlet 12, thereby bringing bad use experience to the user.

In the embodiment of the utility model, a gap is formed between one end of the reinforcing rib 31 and the air outlet upper wall 221, so that the thickness of the air outlet upper wall 221 can be kept uniform, and the cooling speed in the die is equal during processing, namely, the air outlet upper wall 221 has no appearance defects such as shrinkage, dent and the like, and the surface of the air outlet upper wall 221 is smooth and attractive, so that the overall appearance of the finally formed base 2 is ensured to be better.

According to the wall-mounted air conditioner 100 of the embodiment of the present utility model, one side of the reinforcing rib 31 is spaced apart from the side wall of the recess 3. Therefore, compared with the traditional wall-mounted air conditioner, the air outlet upper wall 221 of the scheme is free of the reinforcing ribs 31 to be connected, and the cooling speed of the air outlet upper wall 221 is uniform as a whole during injection molding, so that the appearance defects such as shrinkage and sinking are avoided, the air outlet upper wall 221 is smooth and attractive, and the overall appearance of the base 2 finally formed is good.

Further, a gap between the other end of the reinforcing rib 31 and the air outlet upper wall 221 is L, where L satisfies: l is more than or equal to 1mm and less than or equal to 3mm. As shown in fig. 8, when the clearance L is smaller than 1mm, the clearance between the other end of the reinforcing rib 31 and the air outlet upper wall 221 is too small, and since the base 2 is generally injection molded, the clearance is too small to be easily controlled, so that the other end of the reinforcing rib 31 is connected to the air outlet upper wall 221 at the time of processing. When the gap L is greater than 3mm, the gap between the other end of the stiffener 31 and the air outlet upper wall 221 is too large, which results in insufficient supporting strength of the stiffener 31, and thus fails to provide a strong supporting force for the wall-mounted air conditioner 100 when dropped.

Therefore, when the gap between the other end of the reinforcing rib 31 and the air outlet upper wall 221 is less than or equal to 1mm and less than or equal to 3mm, the structural strength of the base 2 can be ensured, the supporting force of the reinforcing rib 31 can be increased, the wall-mounted air conditioner 100 is prevented from being seriously damaged when falling, and the wall-mounted air conditioner is convenient to process.

According to some embodiments of the present utility model, the stiffener 31 includes a body 311 and a fitting portion 312, the fitting portion 312 is located at a side of the body 311 adjacent to the housing 1, the fitting portion 312 is spaced apart from the body 311 in the width direction of the housing 1, a fitting groove 3121 is formed on one of the fitting portion 312 and the housing 1, a fitting protrusion 13 is provided on the other of the fitting portion 312 and the housing 1, and the fitting protrusion 13 is fitted in the fitting groove 3121. Wherein, when the fitting groove 3121 is formed on the fitting portion 312, the fitting protrusion 13 is formed on the housing 1 (as shown in fig. 10). When the fitting groove 3121 is formed on the housing 1, the fitting projection 13 (not shown) is formed on the fitting portion 312.

As shown in fig. 9 to 10, when the fitting groove 3121 is formed on the fitting portion 312, the fitting protrusion 13 is formed on the housing 1. The shape of the fitting groove 3121 and the shape of the fitting protrusion 13 are adapted, that is, the fitting protrusion 13 may be embedded in the fitting groove 3121, so as to prevent the fitting protrusion 13 from falling off from the fitting groove 3121, so that the connection between the housing 1 and the base 2 is realized, and the connection between the base 2 and the housing 1 is simple and convenient to operate.

The body 311 extends along the depth direction of the groove 3, the mating portion 312 is located at one end of the body 311 away from the groove 3, and a gap is formed between the mating portion 312 and one side of the body 311 adjacent to the mating portion. So set up, can provide the space for the deformation of cooperation portion 312, avoid cooperation protruding 13 and cooperation groove 3121 assembly back and extrusion body 311 to can avoid strengthening rib 31 to appear breaking, further guaranteed the life of base 2.

Further, one end of the fitting portion 312 is connected to the body 311, the other end of the fitting portion 312 is connected to the bottom wall of the water pan 6, and a part of the fitting portion 312 is recessed toward the body 311 to form a fitting groove 3121, and the outer peripheral surface of the fitting groove 3121 is spaced apart from the body 311 in the width direction of the housing 1. For example, in the example of fig. 2 to 10, the fitting portion 312 extends in the height direction of the housing 1, and both ends of the fitting portion 312 are connected to the body 311 and the inside of the groove 3, respectively. The middle portion of the fitting portion 312 is recessed toward the body 311 to form a fitting groove 3121, and the fitting groove 3121 has a substantially circular arc shape. The shape of the fitting projection 13 is cylindrical, which facilitates the fitting of the fitting projection 13 with the fitting groove 3121, and can prevent the fitting projection 13 from coming out of the fitting groove 3121.

So arranged, the structural stress of the reinforcing ribs 31 to the side walls of the grooves 3 is reduced while the structural strength of the fitting portions 312 is ensured. When the wall-mounted air conditioner 100 falls down during the handling or production process, the fitting portion 312 and the body 311 can provide supporting force for the base 2 and the housing 1 to mitigate damage of the wall-mounted air conditioner 100, and the gap between the fitting groove 3121 and the body 311 can provide space for deformation of the stiffener 31.

According to some embodiments of the present utility model, the outer circumferential surface of the fitting groove 3121 is spaced apart from the air outlet upper wall 221 in the height direction of the housing 1. By this arrangement, when the base 2 is injection-molded, the stress generated on the surface of the air outlet upper wall 221 by the fitting groove 3121 can be avoided, and the surface of the air outlet upper wall 221 can be free from the appearance defects such as shrinkage and dent.

According to some embodiments of the present utility model, the partial body 311 is recessed away from the mating portion 312 to form a first escape groove 313, the first escape groove 313 is opposite to the mating groove 3121, and/or the partial body 311 is recessed away from the indoor heat exchanger 4 in the height direction of the housing 1 to form a second escape groove 314. The body 311 may be formed with a first avoidance groove 313 and a second avoidance groove 314 at the same time; or only the first avoiding groove 313 may be formed in the body 311; still alternatively, only the second escape groove 314 may be formed in the body 311.

Referring to fig. 2 to 9, the first avoidance groove 313 is formed at one end of the body 311 adjacent to the mating portion 312, and the shape of the first avoidance groove 313 is arc-shaped, so that the shape of the mating portion 312 is matched with the shape of the first avoidance groove 313, thereby enabling the body 311 to be spaced apart from the mating portion 312, ensuring the structural strength of the body 311, reducing the material consumption of the reinforcing ribs 31, and reducing the weight of the base 2. The second avoidance groove 314 is formed at one side of the body 311 in the width direction away from the air outlet 12, and the second avoidance groove 314 extends in the depth direction of the groove 3, so that the body 311 is prevented from interfering with other components.

According to some embodiments of the present utility model, one end of the fitting portion 312 protrudes from the body 311 in the height direction of the housing 1. As shown in fig. 2, the side of the engaging portion 312 away from the air outlet 12 protrudes out of the main body 311, and when the engaging protrusion 13 engages with the engaging groove 3121, the force applied to the engaging portion 312 can be dispersed more widely, so that the engaging portion 312 can be prevented from being deformed, and the supporting effect of the reinforcing rib 31 can be ensured.

According to some embodiments of the utility model, the wall-mounted air conditioner 100 further includes a thermal insulation. The heat preservation part is filled in the groove 3.

Therefore, the heat preservation piece is filled in the groove 3, the heat preservation piece can preserve heat of the air-out upper wall 221, and then the temperature of condensed water in the water receiving disc 6 can be prevented from being transferred to the air-out upper wall 221, so that the air-out upper wall 221 is prevented from shrinking and deforming when encountering cold, and meanwhile, the heat preservation piece can play a supporting role.

Wherein, the heat preservation piece can be the heat preservation foam piece. The heat-insulating foam has the characteristics of easy cutting and installation, convenient construction, time saving, low heat capacity, low heat conductivity, high refractoriness, high heat sensitivity and the like, can be used for a long time in neutral and oxidizing atmospheres, and has excellent wind erosion resistance, mechanical impact resistance, sound absorption and fire resistance. Therefore, the heat-insulating foam can not only effectively isolate the temperature of the condensed water in the water receiving disc 6, but also has a supporting function, and the stress of the reinforcing ribs 31 is reduced.

According to some embodiments of the utility model, the cross-sectional area of the groove 3 gradually decreases in the width direction of the housing 1 toward the center of the base 2. For example, in the examples of fig. 2 to 4, the cross-section of the groove 3 is triangular, which makes the structural strength of the groove 3 stronger and also facilitates the better support provided by the ribs 31.

According to some embodiments of the utility model, the number of the reinforcing ribs 31 is plural, and in the description of the utility model, the meaning of "plural" is two or more. The plurality of reinforcing ribs 31 are uniformly spaced apart in the length direction of the housing 1. Referring to fig. 2, 5 and 7, the plurality of reinforcing ribs 31 may increase the supporting force to the groove 3, and the reinforcing ribs 31 are spaced apart to uniformly stress each reinforcing rib 31, so that the wall-mounted air conditioner 100 is prevented from being damaged during the carrying process or falling, and the service life of the wall-mounted air conditioner 100 is prolonged.

For example, in the example of fig. 2, the number of the reinforcing ribs 31 is two, and the two reinforcing ribs 31 are arranged at intervals in the groove 3, so that the supporting force of the reinforcing ribs 31 to the groove 3 can be increased.
