Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a hanging type air conditioner. Background Art

[0002] The wall mounted air conditioner includes an air conditioner indoor unit. The housing of the air conditioner indoor unit includes at least an air conditioner air inlet and an air conditioner air outlet connected to the indoor room. A heat exchange fan, a fresh air volute and an indoor heat exchanger are arranged inside the housing. The heat exchange fan is used to introduce indoor air into the housing from the air conditioner air inlet, and after heat exchange in the indoor heat exchanger, it flows to the indoor room from the air conditioner air outlet. A fresh air fan is arranged in the fresh air volute, and the fresh air volute includes at least a fresh air inlet and an indoor air outlet. The fresh air fan rotates to let the outdoor fresh air enter the fresh air volute through the fresh air inlet, and flow to the indoor room through the indoor air outlet, thereby realizing the fresh air function.

[0003] The fresh air volute may also include a purification air inlet, and a filter assembly is arranged inside the fresh air volute. The fresh air fan rotates to allow indoor air to enter the fresh air volute through the purification air inlet, and then flow into the room after being filtered and purified by the filter assembly, thereby realizing the indoor air internal circulation purification function. In the related art, when both fresh air and purification functions are installed, the following scheme is adopted: 1. A separate valve or baffle needs to be set for the opening and closing of each air outlet, and a separate driving member needs to be set accordingly to drive its movement to realize the opening and closing of the air outlet. 2. A driving member is used to control a valve or baffle to realize the mutually exclusive opening of the fresh air inlet and the purification air inlet.

[0004] Solution 1 will result in the need to set up more driving components for the fresh air module to correspond to it. The driving components are generally large in size, occupy a large space, and are expensive, which leads to the overall large size and high cost of the fresh air module. In addition, too many driving components increase the failure rate of the fresh air module, making the operation reliability of the fresh air module low. Compared with Solution 1, Solution 2 reduces the cost to a certain extent, but it cannot realize the simultaneous opening or closing of the fresh air function and the purification function, and the user experience is poor.

[0083] It should be noted that the direction described in the article is based on the direction in which the user faces the air-conditioning indoor unit, wherein the side of the air-conditioning indoor unit facing the user when in use is defined as the front side, the opposite side is defined as the rear side, and the left and right sides are distinguished based on the direction in which the user faces the air-conditioning indoor unit.

[0084] A heat exchange air duct is formed inside the housing 1. The heat exchange air duct is used to accommodate and fix various components in the air conditioner indoor unit 100, which can prevent foreign objects from colliding with the various components in the housing 1, thereby improving the reliability of the air conditioner indoor unit 100 during transportation or installation.

[0085] In some embodiments of the present application, reference Figure 2 The housing 1 may include an air-conditioning air inlet 13 .

[0086] The air conditioning inlet 13 is connected to the heat exchange duct. The air conditioning inlet 13 serves as an inlet for the external air to flow into the housing 1 , allowing the indoor air to enter the heat exchange duct through the air conditioning inlet 13 .

[0087] In some embodiments of the present application, reference Figure 2 The housing 1 may include an air conditioning outlet 14 .

[0088] The air conditioning outlet 14 is connected to the heat exchange air duct, and serves as an outlet for the heat exchange air flow in the shell 1 to flow out, allowing the air flow in the heat exchange air duct to flow out from the air conditioning outlet 14 .

[0113] The air conditioner may include a throttling device. The throttling device is used for throttling. The throttling device may be provided in an indoor unit of the air conditioner or an outdoor unit of the air conditioner.

[0114] The air conditioner performs the refrigeration cycle of the air conditioner by using a compressor, a condenser, a throttling device 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.

[0115] The compressor compresses the refrigerant gas in a low-temperature and low-pressure state and discharges the refrigerant gas in a high-temperature and high-pressure state, and the discharged refrigerant gas flows into the condenser.

[0116] The condenser condenses the compressed refrigerant into liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0117] The throttle device expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant.

[0118] The evaporator evaporates the refrigerant expanded in the throttling device and returns the refrigerant gas in a low temperature and low pressure state to the compressor.

[0119] The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the whole cycle, the air conditioner can adjust the temperature of the indoor space.

[0120] Of the indoor heat exchanger and the outdoor heat exchanger, one is a condenser and the other is 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.

[0122] A second partition portion 112 is disposed inside the housing 1. The first partition portion 111 and the second partition portion 112 are disposed correspondingly and spaced apart along the length direction of the housing 1, and together define a first inner cavity 18 for installing the heat exchange fan 3.

[0123] The first partition portion 111 and the second partition portion 112 can also be used to limit the heat exchange fan 3 axially to prevent the heat exchange fan 3 from moving along the length direction of the housing 1 , thereby increasing the reliability of the installation of the heat exchange fan 3 .

[0124] In some embodiments of the present application, a second inner cavity 19 is formed in the housing 1. The second inner cavity 19 and the first inner cavity 18 are separated from each other by a first partition portion 111, so that the first inner cavity 18 and the second inner cavity 19 are arranged along the length direction.

[0125] In some embodiments of the present application, in order to realize the fresh air function, the air conditioner indoor unit may include a fresh air module. The fresh air module is used to introduce outdoor fresh air into the room.

The two are mixed and filtered by the filter component 43, and finally flow into the room through the indoor air outlet 42, so that the wall-mounted air conditioner turns on the fresh air function and the purification function at the same time, realizing the introduction of outdoor fresh air and the internal circulation purification of indoor air.

[0182] in, Fig.18 The dotted line depicted in the figure is used to represent the flow path of the outdoor fresh air, and the arrows on the dotted line are used to represent the flow direction of the outdoor fresh air; Fig.18 The solid line depicted therein is used to represent the flow path of the indoor air, and the arrows attached to the solid line are used to represent the flow direction of the indoor air.

[0183] refer to Fig.19 When the baffle 6 is in the fourth position, the front end of the baffle 6 abuts against the front end of the sliding portion 45, and the rear part of the baffle 6 blocks the connection between the fresh air inlet 41 and the fresh air duct 44.

[0184] When the baffle 6 is in the fourth position, the fresh air fan 5 is running, and the indoor air enters the fresh air duct 44 through the purification air inlet 46, and after being filtered by the filter component 43, it flows into the room through the indoor air outlet 42, so that the wall-mounted air conditioner starts the purification function, realizing the internal circulation purification of the indoor air. Fig.19 , Fig.19 The solid line depicted therein is used to represent the flow path of the indoor air, and the arrows attached to the solid line are used to represent the flow direction of the indoor air.

[0185] In some embodiments of the present application, reference Fig. 20In the length direction of the first side wall 471, the distance between the purified air inlet 46 and the fresh air inlet 41 is a, wherein a≥6 mm.

[0186] The spacing a cannot be too small. If it is too small, it will cause air leakage between the fresh air inlet 41 and the purified air inlet 46 and make it inconvenient to connect the fresh air inlet 41. In order to separate the purified air inlet from the fresh air inlet and facilitate the connection of the fresh air inlet pipe, the spacing a is set to be not less than the first parameter value. For example, the first numerical parameter can be 6mm, 6.5mm, or 7mm. Consider selecting a suitable and specific parameter in the specific design.

[0187] In some embodiments of the present application, in the length direction of the first side wall 471, the distance between the purified air inlet 46 and the fresh air inlet 41 is a, where a≤20 mm.

[0188] The spacing a cannot be too large, otherwise the thickness of the fresh air module will be too large, which will in turn cause the thickness of the air conditioner indoor unit 100 of the wall-mounted air conditioner to be too large, increasing the size of the entire machine. In order to reduce the size of the entire machine, the spacing a is set not to exceed the second parameter value. For example, the second numerical parameter can be 20 mm, 19 mm, or 18 mm. Consider selecting a suitable and specific parameter during the specific design.

[0189] In some embodiments of the present application, in the length direction of the first side wall 471, the spacing between the purified air inlet 46 and the fresh air inlet 41 is a. Among them, 6mm≤a≤20mm. Keeping the spacing a within a reasonable range can effectively avoid air leakage between the two air outlets and effectively avoid increasing the thickness of the whole machine.

[0190] In some embodiments of the present application, the first side wall 471 extends along the thickness direction of the shell, and the size of the fresh air inlet 41 in the thickness direction of the shell is L. Wherein, L≥15 mm.

[0191] The dimension L cannot be too small. If it is too small, the fresh air inlet 41 will not be conducive to air intake, which will lead to too small fresh air volume, poor fresh air function effect, and will be unfavorable for the processing of the fresh air inlet 41. In order to increase the fresh air intake volume, the dimension L of the fresh air inlet 41 in the thickness direction of the shell 1 is set to be not less than the third parameter value. For example, the third numerical parameter can be 15mm, 15.5mm, or 16mm. Consider selecting a suitable and specific parameter in the specific design.

[0192] In some embodiments of the present application, the dimension of the fresh air inlet 41 in the thickness direction of the housing 1 is L, wherein L≤40 mm.

[0193] The dimension L cannot be too large, otherwise the thickness of the fresh air module will be too large, which will in turn cause the thickness of the air conditioner indoor unit 100 of the wall-mounted air conditioner to be too large, increasing the size of the entire machine. In order to reduce the size of the entire machine, the dimension L is set not to exceed the fourth parameter value. For example, the fourth numerical parameter can be 40 mm, 39 mm, or 38 mm. Consider selecting a suitable and specific parameter in the specific design.

[0194] In some embodiments of the present application, the dimension of the fresh air inlet 41 in the thickness direction of the housing 1 is L, wherein L≥15 mm and L≤25 mm.

[0195] In this embodiment, the size L of the fresh air inlet 41 is set to any value between 15 mm and 25 mm, which effectively avoids increasing the thickness of the entire machine while ensuring the fresh air intake volume.

[0196] In some embodiments of the present application, the dimension of the fresh air inlet 41 in the thickness direction of the housing 1 is L, wherein L>25 mm, and L≤40 mm.

[0197] In this embodiment, the size L of the fresh air inlet 41 is set to be greater than 15 mm and between 15 mm and 40 mm, so that the thickness of the entire machine can be used with maximum efficiency. Under the limitation of the thickness of the entire machine, the fresh air inlet 41 can obtain the maximum air inlet area.

[0198] In some embodiments of the present application, a dimension of the fresh air inlet 41 in the thickness direction of the shell 1 is L, wherein 15 mm ≤ L ≤ 40 mm.

[0199] In this embodiment, the size L of the fresh air inlet 41 is set to any value between 15 mm and 40 mm, which reduces the size of the whole machine while ensuring that there is sufficient fresh air intake when the fresh air function is turned on, and facilitates the processing of the fresh air inlet 41.

[0200] In some embodiments of the present application, continue to refer to Fig. 20 , the dimension of the fresh air inlet 41 in the thickness direction of the shell 1 is L, and the thickness dimension of the first side wall 471 of the fresh air volute 4 in the thickness direction of the shell 1 is M, where M≥8L

[0201] In this embodiment, the thickness dimension M of the first side wall 471 in the thickness direction of the housing 1 is approximately 8L. Taking the rear end of the first side wall 471 as the starting point, the fresh air inlet 41 is approximately located at the 4L position of the first side wall 471, and the purified air inlet 46 is approximately located at the 5L position of the first side wall 471.

[0202] The length of the baffle 6 is not less than 5L. With the rear end of the baffle 6 as the starting point, the first opening 7 is approximately located at the 3L position of the baffle 6, and the second opening 8 is approximately located at the 2L position of the baffle 6.

[0203] The wall-mounted air conditioner provided in this embodiment can utilize the thickness of the entire machine with maximum efficiency. Under the condition of thickness limitation, the fresh air inlet 41 and the purified air inlet 46 can obtain the maximum air inlet area.

[0204] In some embodiments of the present application, the air conditioner indoor unit 100 may include a second drive motor 113 , wherein the second drive motor 113 is installed on the base 11 .

[0205] The second driving motor 113 is connected to one end of the heat exchange fan 3 away from the fresh air volute 4 to drive the heat exchange fan 3 to rotate.

[0206] refer to Fig.21 The other end of the heat exchange fan 3 is connected to the fresh air fan 5 through the connecting shaft 31, and the rotation of the heat exchange fan 3 drives the fresh air fan 5 to rotate.

[0207] In this embodiment, a single second drive motor 113 is used to simultaneously drive the fresh air fan 5 and the heat exchange fan 3 to operate, which can reduce the use of fresh air motors and save motor costs. At the same time, the fresh air module can be miniaturized, thereby reducing the length of the entire machine, making the structural layout and design more reasonable, thereby improving space utilization and saving plastic material costs.

[0208] It is understandable that when the fresh air fan 5 and the heat exchange fan 3 are driven by the second drive motor 113, if the user does not want to introduce fresh air into the room, but only wants to drive the heat exchange fan 3 to exchange heat for the indoor air, the baffle 6 is slid to the fourth position to close the fresh air inlet 41 to avoid introducing fresh air into the room.

[0209] At this time, the heat exchange fan 3 is turned on and rotated, thereby driving the fresh air fan 5 to rotate synchronously. Since the fresh air inlet 41 is closed, the rotation of the fresh air fan 5 drives the indoor air to enter the fresh air volute 4 through the purified air inlet 46. The indoor air entering the fresh air volute 4 is filtered by the filter component 43 and discharged to the room through the indoor air outlet 42, thereby avoiding the overload operation of the fresh air fan 5 when the fresh air inlet 41 is closed by the baffle 6, thereby avoiding the problem of aerodynamic noise when the fresh air fan 5 rotates, so that the air flow pressure inside the fresh air module remains stable.

[0210] In some embodiments of the present application, the ratio of the air inlet area of ​​the fresh air inlet 41 to the air inlet area of ​​the purified air inlet 46 is in the range of 1 to 2. By setting the ratio of the air inlet area of ​​the fresh air inlet 41 to the air inlet area of ​​the purified air inlet 46 within a reasonable range, when the fresh air function and the purification function are turned on at the same time, the fresh air intake volume and the purified air intake volume are roughly equal.
