DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] First embodiment

[0029] Please refer to Figure 1The embodiment of the present invention provides an air conditioner base 100 for assembling to form an air conditioner. The bearing fixing seat 130 can be sealed to prevent outside air from entering the air duct 111 through the bearing fixing seat 130, thereby avoiding condensation in the air duct 111, and further preventing the occurrence of water blowing, and providing a good user experience. In this embodiment, the air conditioner base 100 is applied to an air conditioner wall mounted unit, which can blow cold air or hot air into the room to achieve a cooling or heating function.

[0030] The air conditioner base 100 includes a base body 110, a seal 120 and a bearing fixing seat 130. The bearing fixing seat 130 is fixedly mounted on the base body 110, and the bearing fixing seat 130 is used to connect with the crossflow fan blade 200 through a bearing (not shown) so that the crossflow fan blade 200 can rotate relative to the base body 110, thereby realizing the air outlet function. The base body 110 is provided with an air duct 111 for accommodating the crossflow fan blade 200, one end of the bearing fixing seat 130 is used to be set outside the central axis of the crossflow fan blade 200 through a bearing sleeve, and the other end is connected to the seal 120, that is, the end of the bearing fixing seat 130 away from the air duct 111 is connected to the seal 120, and the seal 120 can seal the bearing fixing seat 130 to prevent external air from entering the air duct 111 through the bearing fixing seat 130.

[0031] It should be noted that the crossflow blade 200 is disposed in the air duct 111 and can rotate in the air duct 111. When the crossflow blade 200 rotates, negative pressure is formed in the air duct 111, and the outside air enters the air duct 111 through the bearing fixing seat 130 under the action of the negative pressure, that is, blows onto the crossflow blade 200. At this time, since the temperature in the air duct 111 is greatly different from the temperature of the outside air, condensation will be generated in the air duct 111 and on the crossflow blade 200. In this embodiment, the bearing fixing seat 130 is sealed by the seal 120 to prevent the outside air from entering the air duct 111 through the bearing fixing seat 130, so as to avoid the phenomenon of condensation in the air duct 111 and on the crossflow blade 200, and the seal 120 will not interfere with the rotation of the crossflow blade 200.

[0032] Please refer to Figure 2In this embodiment, the base body 110 is provided with a side plate 112, the bearing fixing seat 130 is cylindrical, the axial direction of the bearing fixing seat 130 is perpendicular to the side plate 112, and the seal 120 is provided between the side plate 112 and the bearing fixing seat 130, that is, one end of the bearing fixing seat 130 is spaced from the side plate 112 and connected to the seal 120, and the other end of the bearing fixing seat 130 is used to be sleeved outside the bearing for easy installation and maintenance. Specifically, the bearing fixing seat 130 has an installation cavity 131, and the seal 120 can seal one end of the installation cavity 131 to prevent external air from entering the installation cavity 131, thereby preventing external air from entering the air duct 111 through the installation cavity 131.

[0033] It should be noted that one end of the bearing fixing seat 130 is spaced apart from the side plate 112, and a gap 140 is formed between the bearing fixing seat 130 and the side plate 112, through which the outside air can enter the installation cavity 131 and thus enter the air duct 111. In this embodiment, the seal 120 is arranged in the gap 140 and connected to the bearing fixing seat 130, one side of the seal 120 is connected to the bearing fixing seat 130, and the other side is spaced apart from the side plate 112 to prevent the seal 120 from deforming under the condition of thermal expansion and contraction and causing abnormal noise. However, this is not limited to this. In other embodiments, the side of the seal 120 away from the bearing fixing seat 130 can also abut against the side plate 112 to completely block the gap 140 and improve the sealing effect.

[0034] Please refer to Figure 3 and Figure 4 The sealing member 120 includes a blocking portion 121 and a supporting portion 122. The blocking portion 121 is fixedly connected to the supporting portion 122. In this embodiment, the blocking portion 121 and the supporting portion 122 are integrally formed to improve the connection strength. The cross-sectional area of ​​the blocking portion 121 is smaller than the cross-sectional area of ​​the supporting portion 122. The blocking portion 121 extends into the bearing fixing seat 130 and cooperates with the bearing fixing seat 130. The blocking portion 121 can block and seal the bearing fixing seat 130 to prevent external air from entering the installation cavity 131. The supporting portion 122 abuts against the side wall of the bearing fixing seat 130 to further improve the sealing effect and prevent external air from entering the installation cavity 131.

[0035] In this embodiment, the blocking portion 121 and the abutting portion 122 are both circular, and the bearing fixing seat 130 is cylindrical. The diameter of the blocking portion 121 is equal to the inner diameter of the bearing fixing seat 130, and the blocking portion 121 can be closely matched with the bearing fixing seat 130. The diameter of the abutting portion 122 is equal to the outer diameter of the bearing fixing seat 130, so as to ensure that the sealing member 120 and the bearing fixing seat 130 will not interfere with the base body 110 after the assembly is completed.

[0036] It should be noted that the length of the blocking portion 121 along its axial direction is less than or equal to the preset length, so as to prevent the blocking portion 121 from interfering with the bearing in the bearing fixing seat 130 and the central axis of the crossflow fan blade 200 after extending into the bearing fixing seat 130, thereby ensuring that the crossflow fan blade 200 can rotate normally. In this embodiment, the preset length is 8.6 mm, and the length of the blocking portion 121 along its axial direction is less than or equal to 8.6 mm, but it is not limited thereto. In other embodiments, the preset length may be 7 mm or 5 mm. The preset length is not specifically limited and needs to be determined according to the actual product.

[0037] It is worth noting that the edge of the blocking portion 121 away from the supporting portion 122 is in an arc transition, that is, the position where the blocking portion 121 first cooperates with the bearing fixing seat 130 is chamfered to facilitate assembly, improve assembly efficiency, and reduce manpower and time costs.

[0038] In this embodiment, the seal 120 is made of rubber material, so as to utilize the elasticity of the seal 120 itself to make the seal 120 have a better sealing effect on the bearing fixing seat 130. However, it is not limited to this. In other embodiments, the seal 120 can also be made of silicone material or plastic material, and the material of the seal 120 is not specifically limited.

[0039] In this embodiment, the seal 120, the bearing fixing seat 130 and the base body 110 are all separately provided. When the bearing fixing seat 130 is installed on the base body 110, the seal 120 is first matched with the bearing fixing seat 130, and the installation cavity 131 is sealed by the blocking portion 121, and then the bearing fixing seat 130 is installed on the base body 110. However, it is not limited to this. In other embodiments, the seal 120 can be integrally formed with the bearing fixing seat 130, and the seal 120 can also be integrally formed with the base body 110.

[0040] In the air conditioner base 100 described in the embodiment of the present invention, the bearing fixing seat 130 is fixedly mounted on the base body 110, the base body 110 is provided with an air duct 111 for accommodating the crossflow fan blade 200, and the end of the bearing fixing seat 130 away from the air duct 111 is connected to the sealing member 120, and the sealing member 120 can seal the bearing fixing seat 130 to prevent the outside air from entering the air duct 111 through the bearing fixing seat 130. Compared with the prior art, the air conditioner base 100 provided by the present invention adopts the bearing fixing seat 130 fixedly mounted on the base body 110 and the sealing member 120 connected to the bearing fixing seat 130, so that the bearing fixing seat 130 can be sealed to prevent the outside air from entering the air duct 111 through the bearing fixing seat 130, thereby avoiding the generation of condensation in the air duct 111, and further preventing the occurrence of water blowing, and the user experience is good.

[0041] Second embodiment

[0042] Please refer to Figure 5 and Figure 6 An embodiment of the present invention provides an air conditioner base 100 . Compared with the first embodiment, the difference of this embodiment is that the structure of the sealing member 120 is different. The sealing member 120 includes an end cover portion 123 and a sleeve portion 124 .

[0043] It is worth noting that the seal 120 includes an end cover portion 123 and a sleeve portion 124. The sleeve portion 124 is arranged around the edge of the end cover portion 123 and is fixedly connected to the end cover portion 123. In this embodiment, the sleeve portion 124 and the end cover portion 123 are integrally formed to improve the connection strength. The sleeve portion 124 is sleeved outside the bearing fixing seat 130 to fix the relative position of the seal 120 and the bearing fixing seat 130. The end cover portion 123 abuts against the side wall of the bearing fixing seat 130 to seal the bearing fixing seat 130 to prevent external air from entering the installation cavity 131.

[0044] It should be noted that the edge of the sleeve portion 124 away from the end cover portion 123 is rounded, that is, the position where the sleeve portion 124 first cooperates with the bearing fixing seat 130 is rounded to facilitate assembly, improve assembly efficiency, and reduce labor and time costs. In addition, the connection between the sleeve portion 124 and the end cover portion 123 is rounded to improve the strength of the seal 120.

[0045] The beneficial effects of the air conditioner base 100 described in the embodiment of the present invention are the same as those of the first embodiment, and will not be described in detail herein.

[0046] Third embodiment

[0047] Please refer to Figure 7 and Figure 8 The embodiment of the present invention provides an air conditioner base 100 . Compared with the second embodiment, the difference of this embodiment is that the sealing member 120 further includes a flange portion 125 .

[0048] It is worth noting that the seal 120 includes an end cover portion 123, a sleeve portion 124 and a flange portion 125. The flange portion 125 is coaxially arranged with the sleeve portion 124 and fixedly connected to the end cover portion 123. In this embodiment, the flange portion 125 and the end cover portion 123 are integrally formed to improve the connection strength. Specifically, the flange portion 125 is arranged on the inner side of the sleeve portion 124, that is, the diameter of the flange portion 125 is smaller than the diameter of the sleeve portion 124, and the length of the flange portion 125 along its axial direction is equal to the length of the sleeve portion 124 along its axial direction.

[0049] In this embodiment, the flange portion 125 is in a closed annular shape, and an annular cavity 126 is formed between the flange portion 125 and the sleeve portion 124. The annular cavity 126 is used to accommodate the bearing fixing seat 130. The bearing fixing seat 130 can extend into the annular cavity 126 and fit closely with the annular cavity 126. However, it is not limited to this. In other embodiments, the flange portion 125 can also be in a circular arc shape, in which case an arc-shaped cavity for accommodating the bearing fixing seat 130 is formed between the flange portion 125 and the sleeve portion 124; the flange portion 125 can also be in a plurality of circular arc shapes, which are arranged at intervals and combined to form a ring shape, in which case an intermittent annular cavity for accommodating the bearing fixing seat 130 is formed between the flange portion 125 and the sleeve portion 124.

In addition, the connection between the flange portion 125 and the end cover portion 123 is rounded to improve the strength of the seal 120.

[0052] The beneficial effects of the air conditioner base 100 described in the embodiment of the present invention are the same as those of the second embodiment, and will not be repeated here.

[0053] Fourth embodiment

[0054] Please refer to Fig. 9 The present invention provides an air conditioner 10 for controlling indoor temperature. The air conditioner 10 includes an air conditioner base 100, a crossflow fan blade 200 and an evaporator (not shown). The basic structure and principle of the air conditioner base 100 and the technical effects produced are the same as those of the first embodiment. For the sake of brief description, for the parts not mentioned in this embodiment, reference can be made to the corresponding contents in the first embodiment.

[0055] In this embodiment, the air conditioner 10 is a wall mounted air conditioner, the crossflow blades 200 and the evaporator are both arranged in the air duct 111 of the base body 110, the crossflow blades 200 are fixedly installed in the bearing fixing seat 130 through bearings, the bearing fixing seat 130 is fixedly installed in the base body 110, and the crossflow blades 200 can rotate in the air duct 111.

[0056] It should be noted that, during the cooling process in summer, the crossflow blades 200 rotate to generate negative pressure, driving the outside air to enter the air duct 111 through the evaporator. At this time, the evaporator cools, so that the temperature of the air entering the air duct 111 becomes lower, while the temperature of the outside air is higher. If the outside air directly enters the air duct 111, it will cause uneven cooling and heating and generate condensation in the air duct 111. Therefore, in this embodiment, the seal 120 is used to seal the bearing fixing seat 130 to prevent the outside air from directly entering the air duct 111 through the bearing fixing seat 130, thereby avoiding the phenomenon of condensation in the air duct 111 and on the crossflow blades 200.

[0057] The beneficial effects of the air conditioner 10 described in the embodiment of the present invention are the same as those of the first embodiment, and will not be described in detail herein.
