Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air conditioner cabinet and an air conditioner. Background Art

[0002] When the air conditioner is heating, the hot air floats upward, making it difficult to quickly heat the lower air. When cooling, the cold air has a high density and blows out from the bottom. However, the air outlet of the air conditioner can easily affect the comfort during heating, which led to the emergence of upper and lower air outlet cabinets. Upper and lower air outlet cabinets achieve distributed cooling and carpet-style heating, which are more comfortable and have great development prospects. When the air conditioner is turned on for heating, the refrigerant does not have time to generate heat. In order to avoid directly sending out cold air, the air conditioner will send air a few minutes after it is turned on. Since the air conditioner heating has not been turned on for a long time, it is easy for users to mistakenly think that the air conditioner is broken, and slow heating also affects the user experience.

[0003] The applicant has found that the prior art has at least the following technical problems:

[0004] When the air conditioner is turned on for heating, the refrigerant does not have time to generate heat, and there is a delay in blowing out hot air. Users have to wait for a long time, which affects the user experience. Summary of the invention

DETAILED DESCRIPTION

[0029] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0030] The present invention provides an air conditioning cabinet, such as Figure 1-3As shown, it includes an air duct 1, which has the same function as the air duct of the existing air conditioning cabinet, that is, the air flow generated by the centrifugal fan 3. A rotatable heating device 2 is arranged inside the air duct 1. Since the lower air outlet 12 has the greatest effect when the upper and lower air outlet cabinets are heated, the heating device 2 is preferably located near the lower air outlet 12 of the air duct 1, so that the hot air flow generated after heating is discharged from the lower air outlet 12 for carpet heating. Of course, the heating device 2 can also be arranged at the upper part of the air duct 1 near the upper air outlet 11, that is, the air flow at the upper part of the air duct 1 is heated; or the upper and lower parts of the air duct 1 are arranged at the same time, that is, a heating device 2 is arranged near the upper air outlet 11 and the lower air outlet 12, so as to heat the air flow at the upper and lower parts of the air duct 1 at the same time, and the selection can be made according to the use needs. The heating device 2 is arranged to rotate, and the rotating arrangement is convenient to be driven by a motor in the air conditioning cabinet, so that the structure of the heating device 2 can be relatively simple. The airflow generated by the centrifugal fan 3 can pass through the heating device 2 and be heated, and then discharged from the air outlet (upper air outlet 11 and / or lower air outlet 12) of the air conditioning cabinet. The heating method can be electric heating, chemical reaction heating, direct heating of heat medium, etc., which can be set as needed to ensure that the cold air generated by the centrifugal fan 3 can be quickly heated. By setting the heating device 2, the cold air discharged from the lower air outlet 12 can be heated, converted into hot air, and then discharged. When the ambient temperature is low (such as winter) and the air conditioner is needed for heating, the existing upper and lower air outlet air conditioning cabinet will not supply air until a few minutes after the machine is turned on, because the refrigerant has no time to generate heat in the first few minutes after it is turned on. After the present invention heats the generated cold air through the heating device 2, the air outlet can blow out hot air when the heating is turned on. The user no longer needs to wait when using the air conditioner for heating, and the quick blowing of hot air gives the user a better experience.

[0031] As an optional implementation, Figure 4As shown, the heating device 2 includes a motor 21, a motor shaft 22 and a heating net 23. The heating net 23 is heated by electric energy, and the electric energy heating method is simple to implement. Heating can be achieved by passing current into the heating net 23, and it is also convenient to adjust the power as needed to achieve rapid heating. Since the heating net 23 is also convenient for airflow to pass through, the material of the heating net 23 is preferably an existing metal electric heating element, so as to be processed into a mesh, such as nickel-chromium wire (Ni-Cr), iron-chromium-aluminum wire (Fe-Cr-Al), nickel-iron wire (Ni-Fe), nickel-copper wire (Ni-Cu) and the like. The motor 21 is connected to the heating net 23 through the motor shaft 22, and the heating net 23 is connected to the motor shaft 22. The heating net 23 includes a fixed end and a free end, and the fixed end is provided with a sleeve 23a matching the motor shaft 22. The sleeve 23a is sleeved on the motor shaft 22 to achieve the connection between the heating net 23 and the motor shaft 22. When the motor 21 rotates, it drives the motor shaft 22 to rotate together. The motor 21 can drive the heating net 23 to rotate through the motor shaft 22, so as to drive the heating net 23. After the heating net 23 rotates, the contact area between the airflow in the air duct 1 and the heating net 23 can be adjusted. Preferably, the motor 21 is an existing micro-reduction motor, so as to facilitate arrangement and use in the air-conditioning cabinet. The heating net 23 includes an open state and a closed state. In the open state, there is an angle between the heating net 23 and the airflow direction. Preferably, the heating net 23 is perpendicular to the airflow direction. At this time, the contact area between the airflow and the heating net 23 is the largest. At this time, the heating net 23 is energized and can heat the airflow; in the closed state, the heating net 23 is parallel to the airflow direction. At this time, the contact area between the airflow and the heating net 23 is the smallest. At this time, the heating net 23 is not energized and no heating effect is generated. This is also the initial working state and initial position of the heating net 23. The heating net 23 abuts against the inner wall of the air duct 1 through rotation or there is an angle between the heating net 23 and the inner wall of the air duct 1, such as Figure 5-6 As shown, after the heating net 23 is in contact with the inner wall of the air duct 1 and rotates clockwise (clockwise as shown in the figure), a certain angle can be formed between the heating net 23 and the inner wall of the air duct 1. Figure 5 As shown, there is a certain angle between the heating net 23 and the inner wall of the air duct 1. At this time, the heating function of the heating device 2 is turned on, so that the airflow passing through the air duct 1 is heated by the heating net 23 with the maximum efficiency. Figure 6 As shown, the heating net 23 abuts against the inner wall of the air duct 1, and the heating function of the heating device 2 is turned off. The heating net 23 will not block the airflow in the air duct 1, and the efficiency is the same as that of the existing air conditioning cabinet. A structure such as a mutual engagement can be set between the heating net 23 and the inner wall of the air duct 1 to prevent the heating net 23 from automatically sliding down and blocking the passage of airflow when the air conditioner is working normally. Of course, the self-locking function of the motor 21 can also be used to prevent the heating net 23 from rotating when it is not powered. Figure 4As shown, the shape of the heating net 23 is rectangular, and the rectangular structure is convenient for the production and manufacturing of the metal heating element, and the motor 21 drives the heating net 23 to rotate relatively easily. The mesh of the heating net 23 is circular, triangular, quadrilateral or pentagonal. The mesh shape of the heating net 23 can be set as needed to facilitate production and airflow. The specific size is selected according to needs, and of course it is not limited to the above-mentioned geometric shapes, and can also be other convex polygons or concave polygons.

[0032] As an optional implementation, Figure 1-3 As shown, the air conditioner cabinet further includes a shell 4 and an air duct housing 5. The air duct housing 5 and the shell 4 enclose an air duct 1. The cavity structure with upper and lower openings enclosed by the air duct housing 5 and the shell 4 is the air duct 1. The centrifugal fan 3 is connected to the air duct 1. The centrifugal fan 3 is preferably arranged in the middle of the shell 4 and the air duct 1 to achieve uniform upper and lower air discharge, thereby improving the energy efficiency of the air conditioner. The air duct housing 5 includes a first housing 51 and a second housing 52. Preferably, the first housing 51 and the second housing 52 are split structures. The first housing 51 and the second housing 52 are both connected to the shell 4 and arranged opposite to each other. The air duct housing 5 and the shell 4 can be fixed by snap connection, screw connection, etc.

[0033] As an optional implementation, Figure 5-6 As shown, the first shell 51 includes a first end 51a and a second end 51b, the first end 51a is opposite to the second end 51b, and a concave structure is formed between the first end 51a and the second end 51b, so as to facilitate fixing the heating device 2. The motor 21 is connected to the first end 51a, and a screw hole can be set on the first end 51a, and the motor 21 is connected to the first shell 51 by screws. The second end 51b is provided with a pin hole 51c, and the heating net 23 is provided with a pin shaft 24b matching the pin hole 51c (the pin shaft 24b and the sleeve 23a are located on the same side of the heating net), and the heating net 23 can be fixed by inserting the pin shaft 24b into the pin hole 51c. The fixed end of the heating net 23 is fixed with the pin hole 51c and the motor shaft 22, so that the fixing effect is better and the heating net 23 is also convenient for rotation. The lower part of the second shell 52 is provided with a positioning rib 52a, which is preferably manufactured integrally with the second shell 52 (generally, the first shell 51 and the second shell 52 are made of plastic and formed by injection molding, and the positioning rib 52a can be integrally injection molded with the second shell 52). After the heating net 23 rotates, it can abut against the positioning rib 52a. The positioning rib 52a blocks the continued rotation of the heating net 23, thereby limiting the rotation angle of the heating net 23. At this time, the heating net 23 can also heat the passing airflow to the maximum extent. The position of the positioning rib 52a is preferably such that when the heating net 23 abuts against it, the direction of the airflow passing through can be perpendicular to the heating net 23, so as to achieve a better heating effect.

[0034] As an optional implementation, Figure 1-3As shown, the upper and lower junctions of the air duct 1 and the housing 4 form an upper air vent 11 and a lower air vent 12, respectively. The positions and structures of the upper and lower air vents 11 and 12 are the same as those of the existing upper and lower air outlet cabinets, which can realize the simultaneous air outlet of the upper and lower parts of the air conditioning cabinet. A baffle 13 is provided at the upper air vent 11. The baffle 13 can be driven by a gear rack transmission method that is more common in existing air conditioning cabinets, which can reduce the space occupied by the baffle 13 when it moves, thereby reducing the volume of the indoor cabinet. When the baffle 13 is closed, it can block the airflow from the upper air vent 11. At this time, only the heating device 2 is provided at the lower part of the air duct 1. When the air conditioner is turned on for the first few minutes of heating, if the upper air vent 11 is opened, the air conditioner will also blow out cold air, affecting the user experience. At this time, the airflow of the upper air vent 11 is closed by the baffle 13, which can prevent the cold air from blowing out; at this time, the air volume of the lower air vent 12 will increase significantly, which can offset the blocking effect of the heating device 2 on the airflow, and does not affect the air volume of the lower air vent 12. When the air conditioner is stably heating, the baffle 13 is opened, the upper air vent 11 is in an open state, the heating net 23 moves to the initial position (ie, the heating net 23 abuts against the inner wall of the air duct 1), and the air conditioner achieves normal up and down air discharge.

[0035] The working process of a preferred embodiment of the air conditioning cabinet provided by the present invention is as follows: when the air conditioner is turned on for heating, the motor 21 of the heating device 2 rotates, and the heating net 23 is rotated from the initial position to the position abutting against the positioning rib 52a, and the contact area between the airflow and the heating net 23 reaches the maximum. Then, the heating net 23 is powered on to achieve heating, and at the same time, the baffle 13 is closed to close the airflow of the upper air outlet 11, and the air volume of the hot air from the lower air outlet 12 will also increase significantly. After a few minutes (such as 3-5 minutes), when the air conditioner reaches stable heating, stop powering the heating net 23, open the baffle 13 to open the airflow of the upper air outlet 11, and then the motor 21 of the heating device 2 rotates in the opposite direction until it abuts against the inner wall of the air duct 1, and the heating net 23 returns to the initial position.

[0036] An air conditioner includes an air conditioner cabinet, and the air conditioner cabinet is the air conditioner cabinet provided by the present invention. Through the air conditioner cabinet of the present invention, when the ambient temperature is low (such as winter) and the air conditioner needs to be used for heating, since the refrigerant does not have time to generate heat in the first few minutes after it is turned on, the generated cold air is heated by the heating device 2, so that the hot air is discharged through the lower air outlet 12 when the air conditioner is just turned on for heating. The user no longer needs to wait when using the air conditioner for heating, and the hot air can be blown out quickly, which provides a better user experience.

[0037] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
