Description

Technical Field

[0001] The utility model relates to the technical field of mobile air conditioners, and in particular to an air-conditioning air intake refrigeration mechanism and a mobile air conditioner. Background Art

[0002] The air inlet of the mobile air conditioner (hereinafter referred to as the air conditioner) is equipped with an air inlet mechanism (composed of air inlet grille and other components) at the air inlet of the shell. The indoor air is sucked into the air conditioner by the air inlet mechanism, and blown into the room from the air outlet of the air conditioner through the air duct under the action of the compressor to achieve the cooling function. However, in the process of achieving the cooling function, the traditional air conditioner needs the compressor to operate, which often increases the energy consumption of the air conditioner and increases the cost of use; at the same time, the traditional air conditioner often only uses indoor air as the wind source, which leads to poor indoor air quality and the hidden danger of "air conditioning disease".

[0003] The related research on the air inlet refrigeration mechanism of the air conditioner in the prior art, such as the patent application CN203432040U, an air inlet opening and closing mechanism of the air conditioner, can realize the switchable air inlet between indoor and outdoor through the cooperation of the outdoor air inlet duct and the shielding component which can be moved to cover the air inlet on the indoor air inlet grille, and provide two wind sources to participate in heat exchange to a certain extent. However, the prior art still often has the problem that when the air conditioner realizes the refrigeration function, the compressor needs to run, so that the energy consumption of the air conditioner is increased and the use cost is increased. At the same time, the shielding components in the prior art mostly only act on the indoor air inlet grille, and cannot ensure the synchronous linkage of the switches of the indoor and outdoor air inlet, which makes the operation safety and reliability of the air conditioner general.

[0004] Therefore, a new technical solution is needed to solve the above technical problems. Utility Model Content

[0005] The purpose of the utility model is to provide an air-conditioning air intake refrigeration mechanism and a mobile air-conditioning to solve the technical problems raised in the above-mentioned background technology that the prior art often still needs a compressor to run to achieve air-conditioning refrigeration, the air-conditioning energy consumption is increased, the use cost is increased, and the prior art cannot ensure the synchronous linkage of the indoor air intake and outdoor air intake switches, resulting in the general safety and reliability of the air-conditioning operation.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An air-intake cooling mechanism for an air conditioner comprises an indoor air-intake grille, an outdoor air-intake duct, an outdoor temperature sensor, a mesh frame in a rectangular structure, and a shielding door which is movable to shield the indoor air-intake grille or the outdoor air-intake duct, wherein the shielding door is provided with a motor drive assembly for driving the shielding door to move, the motor drive assembly and the outdoor temperature sensor are both electrically connected to a controller of the air conditioner, and the controller can be used to control the motor drive assembly to drive the shielding door to move and control the compressor switch of the air conditioner according to the outdoor temperature detected by the outdoor temperature sensor.

[0008] Furthermore, the indoor air inlet grille is formed on the front panel of the mesh frame and is symmetrically arranged with two of them. The front panel of the mesh frame also forms an outdoor air inlet grille in the middle position of the two indoor air inlet grilles. An outdoor air duct joint for connecting to an outdoor air inlet duct is provided in front of the outdoor air inlet grille. The outdoor air inlet grille is closed and connected to the outdoor air inlet duct. Two shielding doors are arranged in parallel and are vertically arranged inside the mesh frame so as to be movable left and right. The motor drive assembly and the shielding door are arranged in a one-to-one correspondence. The two shielding doors can be respectively shielded behind the two indoor air inlet grilles by two motor drive assemblies, or can be shielded behind the outdoor air inlet grille in a staggered manner.

[0009] Furthermore, the motor drive components each include a drive motor electrically connected to the controller, and the two drive motors are commonly installed on a motor bracket, and the motor bracket is horizontally fixed between the left and right inner walls of the mesh frame. The output ends of the drive motors are also transmission-connected with gears, and the gears are meshingly connected with racks, and the racks are fixed on the inner walls of the corresponding shielding doors and horizontally arranged along the left and right directions. Two proximity switches I and two proximity switches II are also symmetrically fixed on the motor bracket, respectively. The two proximity switches I are respectively located behind two indoor air inlet grilles, and the two proximity switches II are simultaneously located behind the outdoor air inlet grilles. The proximity switches I and II on the same side are commonly provided with magnets that cooperate with them, and the magnets are fixed one-to-one on the inner walls of the shielding doors.

[0010] In addition to the above technical solutions, the utility model also provides a mobile air conditioner, including the above air conditioning air intake refrigeration mechanism.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, on the basis of indoor air inlet grille, outdoor air inlet duct and shielding door, the shielding door is movable to shield the indoor air inlet grille or the outdoor air inlet duct, so that the switch of indoor air inlet and outdoor air inlet can be synchronously linked through the shielding door, thereby greatly improving the operation safety and reliability of the air conditioner. On this basis, the motor drive component for driving the shielding door to move, and the outdoor temperature sensor for detecting the outdoor temperature are arranged in cooperation with the controller of the air conditioner and the compressor of the air conditioner, which effectively solves the problem that the compressor always needs to operate during the refrigeration process of the air conditioner, that is, when the motor drive component and the outdoor temperature sensor are both connected with the controller of the air conditioner, the compressor of the air conditioner can be operated. When the controller is electrically connected, the controller of the air conditioner controls the motor drive assembly to move the shielding door according to the outdoor temperature detected by the outdoor temperature sensor. When the outdoor temperature detected by the outdoor temperature sensor cannot meet the cooling demand, the shielding door blocks the outdoor air inlet duct, the compressor of the air conditioner starts, and the indoor air is introduced through the indoor air inlet grille. The air is cooled by the action of the air conditioner compressor. When the outdoor temperature detected by the outdoor temperature sensor meets the cooling demand, the shielding door blocks the indoor air inlet grille, the compressor of the air conditioner is turned off, and the outdoor air is directly introduced through the outdoor air inlet duct for cooling. This greatly reduces the energy consumption of the air conditioner, reduces the use cost of the air conditioner, and also greatly reduces the operating noise of the machine.

[0013] 2. The utility model has two shielding doors arranged in parallel. The motor drive components in the utility model include a driving motor installed on a motor bracket, a gear transmission-connected to the output end of the driving motor, and a rack meshing with the gear. In the utility model, the motor bracket is arranged behind the two shielding doors, and the racks are fixed to the inner walls of the corresponding shielding doors through a matching arrangement, thereby realizing the linkage coordination between the driving motor and the corresponding shielding door, and ensuring the realization of the shielding door movement operation with a simple structural design, thereby further improving the operating safety and reliability of the air conditioner, and further reducing the use cost of the air conditioner.

[0014] 3. Two proximity switches I and two proximity switches II are fixed on the motor bracket in the utility model, and the outdoor air inlet grille is connected with the outdoor air inlet duct in a closed manner. In the utility model, the two proximity switches I are respectively located behind the two indoor air inlet grilles, and the two proximity switches II are simultaneously located behind the outdoor air inlet grilles. Both the proximity switches I and II are electrically connected to the controller. Through the synergistic effect of the proximity switches I, II and the magnets on the inner wall of the shielding door, the inductive monitoring of the position status of the two shielding doors is realized, and the detection results can be fed back to the controller, which further ensures the operating safety and reliability of the air conditioner.

Two drive motors 9 are fixed symmetrically on the motor brackets 8. The output end of each drive motor 9 is transmission-connected to a gear 10. The gears 10 are meshingly connected to racks 11 one by one. The two racks 11 are horizontally arranged in the left and right directions and are respectively fixed on the inner walls of two shielding doors 4 that are staggered in front and behind. The two shielding doors 4 are vertically and parallelly arranged inside the net frame 5 and can be moved left and right by two drive motors 9 to respectively block the rear of the two indoor air inlet grilles 1 or to block the rear of the outdoor air inlet grille 6 in a staggered splicing manner.

[0028] Furthermore, the motor bracket 8 is fixed with two proximity switches I12 at positions corresponding to the rear of the two indoor air inlet grilles 1, and the motor bracket 8 is fixed with two proximity switches II13 at positions corresponding to the rear of the outdoor air inlet grilles 6. The two proximity switches I12 and the two proximity switches II13 are symmetrically arranged on the left and right, and the proximity switches I12 and II13 on the same side are jointly provided with a magnet 14 that cooperates with them (the normal cooperation mode of the proximity switch and the magnet is well known in the art, so it is not explained here), and the two magnets 14 are respectively fixed on the inner walls of the two shielding doors 4.

[0029] Furthermore, the drive motor 9, the outdoor temperature sensor 3, the proximity switch I 12, and the proximity switch II 13 are all electrically connected to the air conditioner controller 18 (the specific electrical connection settings between the normal air conditioner controller and the components it controls are well known in the art, so they are not explained in detail here and are not shown in detail in the accompanying drawings. At the same time, as common knowledge, the air conditioner controller 18 is electrically connected to the air conditioner compressor 15).

[0030] The working principle and workflow of the utility model are as follows:

[0031] Indoor air intake cooling: When the outdoor temperature detected by the outdoor temperature sensor 3 cannot meet the cooling demand (the temperature can be set as needed), the two drive motors 9 simultaneously drive the two shielding doors 4 to move to the middle position, and block the outdoor air intake grille 6 from the rear of the outdoor air intake grille 6 (such as Figure 2As shown in the figure, indoor air is introduced through the indoor air inlet grille 1, and the indoor air is blown into the room from the air outlet 16 through the air duct 17, so as to achieve a cooling effect. In this process, the compressor 15 of the air conditioner is started and the compressor 15 is used for cooling.

[0032] Outdoor air cooling: When the outdoor temperature detected by the outdoor temperature sensor 3 meets the cooling demand (the temperature can be set as needed), the two driving motors 9 drive the two shielding doors 4 to move to the left and right sides respectively, and shield the two indoor air inlet grilles 1 from behind (such as Figure 6 As shown in the figure, outdoor air is introduced into the room through the outdoor air inlet pipe 2 and the outdoor air inlet grille 6, and the indoor air is blown into the room from the air outlet 16 through the air duct 17, so as to achieve a cooling effect.
