Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to a base drainage component, an indoor unit, and an air conditioner. Background Technology

[0002] Air conditioner indoor unit bases are usually equipped with drain holes, which drain water from the base to the outside through drain pipes. In the current technology, due to the structure of the indoor unit itself, the base is prone to accumulating dirt and grime, and the outside is difficult to clean, which leads to problems such as easy blockage of the drain outlet and growth of bacteria. However, apart from a simple defrosting function (only for the evaporator), few air conditioners on the market have other self-cleaning functions for the base water circuit. Dust accumulation on the base and blockage of the drain outlet are difficult to solve, making it difficult to meet users' needs for health protection functions. Utility Model Content

[0003] The main objective of this utility model embodiment is to provide a base drainage assembly, an indoor unit, and an air conditioner, aiming to improve the technical problem of the base water channel being difficult to clean in the prior art.

[0004] An embodiment of this utility model provides a base drainage assembly, comprising: The base includes a water collection chamber and a drain hole communicating with the bottom of the water collection chamber; A first magnetic component is disposed at the top of the water collection cavity, facing the drain hole; A guide extends from the bottom of the first magnetic element into the drain hole; A magnetic float is attracted to the first magnetic component, sleeved on the guide component, and can slide along the guide component; The base drainage assembly is configured such that when the liquid level in the water collection chamber is higher than a first liquid level, the magnetic float rises to open the drainage hole, and when the liquid level in the water collection chamber is lower than a second liquid level, the magnetic float sinks to block the drainage hole.

[0005] In some embodiments, the magnetic float includes a flexible portion and a magnetic portion. The magnetic portion is disposed at one end of the flexible portion near the first magnetic member. The flexible portion has a first through hole along its axial direction, and the magnetic portion has a second through hole along its axial direction. The first through hole and the second through hole are aligned and disposed, and the guide member passes through the first through hole and the second through hole.

[0006] In some embodiments of this utility model, a hollow sub-cavity is provided on the flexible part; And / or, the magnetic part is provided with a hollow sub-cavity.

[0007] In some embodiments of this utility model, the width of the flexible portion gradually increases from the end of the flexible portion away from the first magnetic component to the end of the flexible portion close to the first magnetic component.

[0008] In some embodiments of this utility model, the flexible part and the magnetic part are detachably connected.

[0009] In some embodiments of this utility model, the width of the water collection cavity gradually decreases from the top of the water collection cavity toward the drain hole.

[0010] In some embodiments of this utility model, the water collection cavity includes a first sidewall and a second sidewall, the first sidewall and the second sidewall are arranged around the drain hole, the first sidewall is arranged vertically and the second sidewall is arranged inclined.

[0011] In some embodiments of this utility model, the first magnetic element is an electromagnet.

[0012] In some embodiments of this utility model, an indoor unit is also provided, which includes the aforementioned base drainage assembly.

[0013] In some embodiments of this utility model, this utility model also provides an air conditioner, which includes the aforementioned base drainage assembly.

[0014] This utility model provides a base drainage assembly, an indoor unit, and an air conditioner. The base drainage assembly has a water collection chamber and a drain hole on the base. A first magnetic element is installed on the water collection chamber, and a magnetic float is installed on the drain hole. The buoyancy of the condensate in the water collection chamber and the attraction of the first magnetic element to the magnetic float cause the drain hole to open automatically when the liquid level in the water collection chamber reaches a certain level, thus flushing the water passage of the base. After flushing, the drain hole is resealed. A guide element is used to constrain the movement trajectory of the magnetic float, ensuring that the magnetic float can reset and reseal the drain hole after leaving it. This allows the base drainage assembly to repeatedly flush the water passage of the base. Attached Figure Description

[0022] like Figures 1-4 As shown, this utility model provides a base drainage assembly 10, including a base 100, a first magnetic element 200, a guide element 300, and a magnetic float 400. The base 100 includes a water collection cavity 110 and a drain hole 120 communicating with the bottom of the water collection cavity 110. The first magnetic element 200 is disposed on the top of the water collection cavity 110 and faces the drain hole 120. The guide element 300 extends from the bottom of the first magnetic element 200 into the drain hole 120. The magnetic float 400 is attracted to the first magnetic element 200, sleeved on the guide element 300, and can slide along the guide element 300. The base drainage assembly 10 is configured such that when the liquid level in the water collection cavity 110 is higher than a first liquid level, the magnetic float 400 floats up to open the drain hole 120, and when the liquid level in the water collection cavity 110 is lower than a second liquid level, the magnetic float 400 sinks to block the drain hole 120.

[0023] It should be noted that the water collection chamber 110 is used to receive condensate from the indoor unit, and the drain hole 120 is connected to the drain pipe of the indoor unit. The condensate from the indoor unit can be drained to the outside through the drain hole 120.

[0024] The magnetism of the first magnetic component 200 is different from that of the magnetic float 400, so the two attract each other. The attraction between the first magnetic component 200 and the magnetic float 400 is F1. As the liquid level in the water collection chamber 110 gradually rises, the buoyancy F2 received by the magnetic float 400 gradually increases, and the weight of the magnetic float 400 is G. When the liquid level in the water collection chamber 110 is higher than the first liquid level, the buoyancy F2 received by the magnetic float 400 increases until the attraction F1 is greater than the weight G, that is, when F1 + F2 > G, the magnetic float 400 floats up and opens the drain hole 120. When the liquid level in the water collection chamber 110 drops to the second liquid level or below, F1 + F2 ≤ G, and the magnetic float 400 sinks down and blocks the drain hole 120.

[0025] The magnetic float 400 is sleeved on the guide member 300. The guide member 300 constrains the upward and downward path of the magnetic float 400, ensuring that after the magnetic float 400 floats, it can also return to the drain hole 120 to block the drain hole 120 when it sinks.

[0026] It is understood that the base drainage assembly 10, by setting a water collection chamber 110 and a drain hole 120 on the base 100, and setting a first magnetic element 200 on the water collection chamber 110 and a magnetic float 400 on the drain hole 120, utilizes the buoyancy of the condensed water in the water collection chamber 110 and the attraction of the first magnetic element 200 to the magnetic float 400, so that when the liquid level in the water collection chamber 110 reaches a certain level, the drain hole 120 will automatically open to flush the water passage of the base 100. After flushing, the drain hole 120 will be resealed, and the movement trajectory of the magnetic float 400 will be constrained by the guide element 300 to ensure that the magnetic float 400 can reset and reseal the drain hole 120 after leaving the drain hole 120, so that the base drainage assembly 10 can repeatedly flush the water passage of the base 100.

[0027] In some embodiments, the guide 300 is a rod-shaped structure, with one end connected to the first magnetic element 200 and the other end extending into the drain hole 120.

[0028] In some embodiments, the magnetic float 400 includes a flexible portion 410 and a magnetic portion 420. The magnetic portion 420 is disposed at one end of the flexible portion 410 near the first magnetic member 200. The flexible portion 410 is provided with a first through hole along its axial direction, and the magnetic portion 420 is provided with a second through hole along its axial direction. The first through hole and the second through hole are aligned and disposed, and the guide member 300 passes through the first through hole and the second through hole.

[0029] It should be noted that the flexible part 410 is used to block the drain hole 120, and the magnetic part 420 is used to receive the attraction of the first magnetic element 200. The flexible part 410 and the magnetic part 420 can be integrally set or detachably connected.

[0030] For example, the flexible part 410 is generally made of a flexible material such as silicone or rubber so that it extends into the drain hole 120 and blocks the drain hole 120.

[0031] For example, if the magnetic part 420 is a magnet, and it is the S pole, then the first magnetic element 200 is set as the N pole; if the magnetic part 420 is the N pole, then the first magnetic element 200 is the S pole.

[0032] It is understandable that by placing the magnetic part 420 at the end of the flexible part 410 close to the first magnetic element 200, the entire magnetic float 400 can be kept intact by the magnetic attraction force of the first magnetic element 200.

[0033] In some embodiments, a hollow cavity 401 is provided on the flexible part 410.

[0034] It should be noted that the hollow cavity 401 is a cavity structure disposed within the flexible part 410, which is used to reduce the weight of the flexible part 410 and increase the buoyancy of the flexible part 410.

[0035] In some embodiments, a hollow cavity 401 is provided on the magnetic part 420.

[0036] Referring to the above embodiment, the hollow sub-cavity 401 is a cavity structure disposed within the magnetic part 420, which is used to reduce the weight of the magnetic part 420 and increase the buoyancy of the magnetic float 400.

[0037] In some embodiments, both the flexible part 410 and the magnetic part 420 are provided with hollow cavities 401.

[0038] In some embodiments, the width of the flexible portion 410 gradually increases from one end of the flexible portion 410 away from the first magnetic element 200 to one end of the flexible portion 410 close to the first magnetic element 200.

[0039] It is understandable that the width of the flexible part 410 gradually increases from the bottom to the top. That is, the flexible part 410 is an inverted cone structure or an inverted frustum structure with a smaller bottom width, so that the magnetic float 400 can easily extend into the drain hole 120 when it sinks and block the drain hole 120.

[0040] Furthermore, in some embodiments, in order to facilitate the flexible part 410 to more easily extend into the drain hole 120 when it sinks, the width of the bottom of the flexible part 410 is set to be smaller than the port width of the drain hole 120, and the width of the top of the flexible part 410 is set to be larger than the port width of the drain hole 120.

[0041] It is understandable that by setting the width of the top of the flexible part 410 to be greater than the port width of the drain hole 120, the flexible part 410 can be partially exposed outside the drain hole 120, making it more susceptible to the buoyancy of the condensate in the water collection chamber 110, thereby making the magnetic float 400 easier to float.

[0042] In some embodiments, the flexible part 410 and the magnetic part 420 are detachably connected.

[0043] It is understandable that the flexible part 410 and the magnetic part 420 are detachably connected, so that only one part needs to be replaced if the flexible part 410 or the magnetic part 420 is damaged, thus saving maintenance costs.

[0044] For example, one of the flexible part 410 and the magnetic part 420 is provided with a snap-fit ​​hole, and the other is provided with an elastic snap-fit, that is, the flexible part 410 and the magnetic part 420 are snapped together by inserting the elastic snap-fit ​​into the snap-fit ​​hole.

[0045] For example, the flexible part 410 and the magnetic part 420 are connected by threads. That is, the bottom of the magnetic part 420 is provided with a threaded post, and the flexible part 410 is provided with a threaded hole. The threaded post is screwed into the threaded hole, so that the magnetic part 420 and the flexible part 410 are detachably connected.

[0046] In some embodiments, the width of the water collection cavity 110 gradually decreases from the top of the water collection cavity 110 toward the drain hole 120.

[0047] It is understandable that by gradually narrowing the width of the water collection cavity 110 from its top toward the drain hole 120, the water collection cavity 110 is made to approximate an inverted cone or an inverted frustum. This results in some or all of the side walls of the water collection cavity 110 being inclined, allowing the water collection cavity 110 to drain through the drain hole 120 with a faster flow rate, thus providing a better rinsing effect when the condensate washes the water path of the base 100.

[0048] In some embodiments, the water collection cavity 110 includes a first sidewall and a second sidewall, which are arranged around the drain hole 120. The first sidewall is arranged vertically and the second sidewall is arranged inclined.

[0049] In some embodiments, the first magnetic element 200 is an electromagnet.

[0050] It is understandable that by setting the first magnetic component 200 as an electromagnet, the magnetism and magnetic force of the first magnetic component 200 can be changed, thereby adjusting the position of the magnetic float 400.

[0051] For example, when it is necessary to open the drain hole 120 at the second liquid level, the current of the electromagnet is increased, so that F1+F2>G. That is, when the buoyancy of the magnetic float 400 is small, the attraction of the first magnetic element 200 on the magnetic float 400 is increased, so that F1+F2>G. For example, when it is necessary to keep the drain hole 120 closed at the first liquid level, the direction of the current of the electromagnet is changed so that the magnetism of the electromagnet is the same as that of the magnetic float 400. This causes the magnetic float 400 to be subjected to the repulsive force exerted by the first magnetic element 200. As a result, the repulsive force of the first magnetic element 200 is in the same direction as the gravity of the magnetic float 400, resisting the buoyancy of the magnetic float 400. This allows the magnetic float 400 to block the drain hole 120 even when the water collection chamber 110 is at the first liquid level or even a higher liquid level.

[0052] Furthermore, a liquid level probe is installed in the water collection cavity 110. The control center of the air conditioner can adjust the magnetism and magnetic force of the electromagnet according to the liquid level in the water collection cavity 110 to open and close the drain hole 120.

[0053] In one embodiment, the present invention also provides an indoor unit, which includes the aforementioned base drainage assembly 10. Since the indoor unit has the aforementioned base drainage assembly 10, that is, includes some or all of the aforementioned base drainage assembly 10 embodiments, the corresponding indoor unit has the beneficial effects of some or all of the aforementioned base drainage assembly 10 embodiments.

[0054] In some embodiments, the present invention also provides an air conditioner that includes the aforementioned base drainage assembly 10. Since the air conditioner has the aforementioned base drainage assembly 10, that is, includes some or all of the aforementioned base drainage assembly 10 embodiments, the corresponding air conditioner has the beneficial effects of some or all of the aforementioned base drainage assembly 10 embodiments.

[0055] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made based on the contents of the present utility model specification and drawings under the application concept of the present utility model, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
