Technical Field

The application relates to the technical field of refrigeration, in particular to an air conditioner and a defrosting structure thereof.

Background

With the development of refrigeration technology, air conditioners have been widely used in assembly equipment such as trains, airplanes, automobiles, and the like. A conventional air conditioner generally includes a cabinet and a condenser. When the air conditioner is used in summer, the condenser reduces the temperature of the refrigerant by absorbing the heat of the refrigerant so as to realize refrigeration; when the condenser is used in winter, the condenser can increase the temperature of the refrigerant by releasing heat to the refrigerant, so as to realize heating. However, since the condenser itself has a low temperature after releasing heat, the condenser is easily frosted.

The condenser after frosting has increased thermal resistance and reduced heat exchange capacity, so the condenser needs to be defrosted regularly. The conventional defrosting mode is to switch the air conditioner to a mode for use in summer, and the condenser performs defrosting by absorbing heat in a refrigerant. However, this method will result in a great loss of the heating performance of the air conditioner in winter, and a reduction in the heating performance of the air conditioner.

SUMMERY OF THE UTILITY MODEL

Accordingly, it is necessary to provide an air conditioner having excellent cooling performance and a defrosting structure thereof, in order to solve the problem of the reduction in cooling performance of the air conditioner.

A defrosting structure is arranged in a casing of an air conditioner, wherein the air conditioner is arranged on assembly equipment, the defrosting structure has a defrosting state with the natural frequency being the same as the vibration frequency of the assembly equipment in the operation process and an undetermined state with the vibration frequency being different from the vibration frequency of the assembly equipment in the operation process, and when the defrosting structure is in the defrosting state, the defrosting structure swings back and forth and is used for defrosting a heat exchanger in the casing of the air conditioner.

In one embodiment, the defrosting device comprises a defrosting assembly and an operating assembly, wherein the defrosting assembly and the operating assembly are both connected in the machine shell in a matching mode;

when the defrosting structure is in the undetermined state, the operating assembly is separated from the defrosting assembly, and the natural frequencies of the defrosting assembly and the operating assembly are different from the vibration frequency of the assembling equipment in the operation process.

In one embodiment, the defrosting assembly comprises a defrosting base and a defrosting piece matched and connected with the defrosting base, the operating assembly comprises an operating base and an operating piece matched and connected with the operating base, and the operating piece is controlled to slide relative to the operating base and is contacted with or separated from the defrosting base;

and when the defrosting state is achieved, the defrosting piece swings back and forth and is used for defrosting the heat exchanger.

In one embodiment, the operating member is a magnetic member;

when the defrosting structure is in the defrosting state, the operating piece slides to be in contact with the defrosting base under the action of the magnetic attraction force of the defrosting base.

In one embodiment, the defrosting base comprises a base body and an electromagnet matched and connected with the base body;

according to any one of the above defrosting structures, the defrosting structure is located in the accommodating cavity, and when the defrosting structure is in the defrosting state, the defrosting structure swings back and forth and is used for defrosting the heat exchanger.

According to the air conditioner and the defrosting structure of the air conditioner, the defrosting structure and the heat exchanger are arranged in the shell of the air conditioner, when the heat exchanger frosts, the defrosting structure is switched to the defrosting state, the natural frequency of the defrosting structure in the defrosting state is the same as the vibration frequency of the assembly equipment in the operation process, and therefore the defrosting structure and the assembly equipment resonate and swing in a reciprocating mode. In the swinging process of the defrosting structure, the defrosting structure continuously knocks the heat exchanger so as to defrost the heat exchanger.

Referring to fig. 1, the present application provides an air conditioner 1, and the air conditioner 1 is installed on an assembly device and used for cooling or heating the inside of the assembly device. Alternatively, the assembly equipment may be a train, an airplane, an automobile, or other large manufacturing equipment. The assembly equipment has a working space in which the air conditioner 1 is located and cools or heats the working space during operation.

Referring to fig. 2, specifically, the air conditioner 1 includes a casing, a heat exchanger 20 and a defrosting structure 10, the casing has a receiving cavity, and the heat exchanger 20 and the defrosting device are both connected to and located in the receiving cavity. The heat exchanger 20 is configured to exchange heat with a refrigerant flowing therethrough to lower or raise a temperature of the refrigerant, and the defrosting device is configured to defrost the heat exchanger 20. Specifically, the heat exchanger 20 may be a condenser or an evaporator. Taking the heat exchanger 20 as an example of a condenser, when the air conditioner 1 performs cooling, the heat exchanger 20 reduces the temperature of the refrigerant by absorbing heat of the refrigerant, so as to perform cooling. When the air conditioner 1 heats, the heat exchanger 20 increases the temperature of the refrigerant by releasing heat to the refrigerant, thereby achieving heating. In the heating process of the air conditioner 1, the temperature of the heat exchanger 20 after releasing heat is reduced, so the heat exchanger 20 is easy to frost, and the heat exchange efficiency of the air conditioner 1 is reduced.

The defrosting structure 10 has an undetermined state and a defrosting state, when the defrosting structure 10 is in the defrosting state, the natural frequency of the defrosting structure 10 is the same as the vibration frequency of the assembly equipment in the operation process, and when the defrosting structure 10 is in the undetermined state, the vibration frequency of the defrosting structure 10 is different from the vibration frequency of the assembly equipment in the operation process. When the defrosting structure 10 is in the defrosting state, the defrosting structure 10 is reciprocated and used to defrost the heat exchanger 20. Specifically, when the defrosting structure 10 swings, the defrosting structure 10 intermittently strikes the heat exchanger 20, so that the frost adhered to the heat exchanger 20 can move relative to the heat exchanger 20 and fall off the heat exchanger 20, and thus defrosting can be achieved.

In the conventional air conditioner 1, it is generally adopted to switch the air conditioner 1 from a heating mode to a cooling mode, and to defrost the heat exchanger 20 in the cooling mode. In this way, the heating performance of the air conditioner 1 is sacrificed, and the heating performance of the air conditioner 1 is degraded. In the present application, since the heat exchanger 20 is defrosted by using vibration during the operation of the mounting apparatus, the air conditioner 1 can continuously perform heating, and thus has superior heating performance. In addition, extra energy does not need to be provided in the defrosting process, so that energy can be saved, and the air conditioner 1 has the characteristic of low energy consumption.

Preferably, the defrosting structure 10 is plural, and the plurality of defrosting structures 10 are arranged at intervals along the longitudinal direction of the heat exchanger 20, so that the defrosting device can defrost the heat exchanger 20 in a full-scale manner.

When the defrosting structure 10 is in the defrosting state, the natural frequency of the defrosting structure 10 may be set to be the same as the vibration frequency of the assembly equipment after the assembly equipment operates stably, or the natural frequency of the defrosting structure 10 may be set to be the same as the vibration frequency of the assembly equipment during high-speed operation or low-speed operation, and specifically, the natural frequency may be set according to the actual operation requirement of the assembly equipment.

Furthermore, since the natural frequency is related to the mass, volume, density, or the like of the defrost structure 10, the change in the natural frequency of the defrost structure 10 can be achieved by changing at least one of the mass, volume, or density of the defrost structure 10, thereby enabling the defrost structure 10 to switch between the defrost state and the pending state.

Referring to fig. 3 and 5, in an embodiment, the defrosting structure 10 includes a defrosting assembly 11 and an operating assembly 13, and the defrosting assembly 11 and the operating assembly 13 are both mounted in the cabinet. When the defrosting structure 10 is in a defrosting state, the operating component 13 is in contact with the defrosting component 11, the natural frequency of the combination of the defrosting component 11 and the operating component 13 is the same as the vibration frequency of the assembly equipment during operation, and at least one of the defrosting component 11 and the operating component 13 swings back and forth and is used for defrosting the heat exchanger 20. It can be understood that, when the assembly equipment is in operation and the defrosting structure 10 is in the defrosting state, the operating component 13 is in contact with and spliced with the defrosting component 11 to form a whole, at this time, the natural frequency of the whole defrosting structure 10 is the same as the vibration frequency when the assembly equipment is in motion, the operating component 13 and the defrosting component 11 both vibrate in an oscillating manner, and at least one of the defrosting component 11 and the operating component 13 intermittently contacts with the heat exchanger 20 and defrosts the heat exchanger 20 during the oscillating manner.

When the defrosting structure 10 is in a pending state, the operating component 13 is separated from the defrosting component 11, and the natural frequency of the defrosting component 11 and the operating component 13 is different from the vibration frequency of the assembling equipment in the operation process. It can be understood that, when the operating assembly 13 is separated from the defrosting assembly 11, the volume and the structure of the defrosting structure 10 are changed, at this time, the natural frequency of any one of the defrosting assembly 11 and the operating assembly 13 is different from the vibration frequency of the assembling device during operation, and then the natural frequency of the defrosting structure 10 formed by the defrosting assembly 11 and the operating assembly 13 is also different from the vibration frequency of the assembling device during operation. Therefore, neither the operating unit 13 nor the defrosting unit 11 can resonate with the mounting apparatus, and thus the heat exchanger 20 cannot be defrosted.

It is understood that the natural frequency of any one of the defrosting assembly 11 and the operating assembly 13 is different from the vibration frequency of the assembling device during operation, which means that the natural frequency of the defrosting structure 10 formed by the defrosting assembly 11 and the operating assembly 13 is also different from the vibration frequency of the assembling device during operation. Neither the operating unit 13 nor the defrosting unit 11 can resonate with the mounting apparatus, which means that the defrosting structure 10 cannot resonate with the mounting apparatus.

Further, the defrosting assembly 11 includes a defrosting base 112 and a defrosting member 114 coupled to the defrosting base 112, the operating assembly 13 includes an operating base 132 and an operating member 134 coupled to the operating base 132, and the defrosting base 112 and the operating base 132 are coupled to the machine body. The operating member 134 is controlled to slide with respect to the operating base 132 and to contact or separate from the defrosting base 112. In the defrosting state, the defrosting member 114 is reciprocally swung and serves to defrost the heat exchanger 20. When the operating member 134 contacts the defrosting base 112, the operating base 132, the operating member 134, the defrosting base 112, and the defrosting member 114 are connected to form an integral body. When the defrosting structure 10 is in the defrosting state, the operation base 132, the operation member 134, the defrosting base 112, and the defrosting member 114 resonate, but only the defrosting member 114 intermittently comes into contact with the heat exchanger 20 and defrosts the heat exchanger 20. Thus, the contact area between the defrosting structure 10 and the heat exchanger 20 during the resonance process can be reduced, so as to prevent the defrosting structure 10 from colliding with the heat exchanger 20 at a plurality of positions and being damaged. In addition, the operating member 134 slides linearly relative to the operating base 132, which improves the stability of the sliding of the operating member 134 and enables the operating member to quickly contact the defrosting base 112 and resonate. It can be seen that the defrosting structure 10 can respond quickly and has high defrosting efficiency.

Preferably, the defrost member 114 is removably coupled to the defrost base 112. Therefore, when the defroster 114 is deformed or broken, the broken defroster 114 can be replaced.

Referring to fig. 7, the operating base 132 is further provided with a slide 1322 for guiding the operating element 134 to slide. The operating member 134 can stably slide and contact the defrost base 112 under the guidance of the slide 1322. Alternatively, the slide 1322 may be a slide rail, a slide slot, or the like, merely ensuring that the operating member 134 is able to slide and does not deflect.

Referring to fig. 6, the operating member 134 is provided with a first bayonet 1341 facing the defrosting base 112. When the defrosting structure 10 is in the defrosting state, the defrosting base 112 is at least partially retained in the first bayonet 1341. In this way, it is helpful to improve the reliability of the contact of the operating member 134 with the defrost base 112 to prevent the operating member 134 from being separated from the defrost base 112 when the defrost structure 10 resonates with the mounting apparatus.

Further, one end of the operating element 134 away from the first bayonet 1341 is provided with a second bayonet 1343, and the second bayonet 1343 is disposed opposite to the defrosting base 112. That is, the first and second bayonets 1341 and 1343 are respectively disposed at two opposite ends of the operating element 134, so that the uniformity of the weight distribution of the operating element 134 can be improved, and the situation that one end of the operating element 134 tilts up and the other end of the operating element sinks due to uneven weight in the process of sliding relative to the slide 1322 can be prevented, thereby enabling the sliding of the operating element 134 to be more stable.

Further, the operation member 134 is a magnetic member. When the defrosting structure 10 is in the defrosting state, the operating member 134 slides to contact with the defrosting base 112 by the magnetic attraction force of the defrosting base 112. Specifically, the operation member 134 may be made of metal or magnetic material. When the defrosting structure 10 is in the defrosting state, the magnetic attraction force provided by the defrosting base 112 can pull the operating member 134 to slide until the operating member 134 contacts the defrosting base 112. Compared with other power devices for driving the operating element 134 to slide, the magnetic attraction method for pulling the operating element 134 to slide has lower energy consumption, so that the energy consumption in the defrosting process can be reduced, and the defrosting structure 10 has the characteristic of low energy consumption.

Referring to fig. 4, preferably, the defrosting base 112 includes a base body 1121 and an electromagnet 1123 coupled to the base body 1121. When the defrosting structure 10 is in the defrosting state, the electromagnet 1123 is energized and generates a magnetic attraction force. Under the action of the magnetic attraction force, the operation element 134 can slide to contact with the seat body 1121 and/or the electromagnet 1123.

Specifically, the seat body 1121 has a receiving cavity 1125, and the electromagnet 1123 is received in the receiving cavity 1125 of the seat body 1121. Because the humidity in the cabinet is relatively high during the heat exchange or defrosting process of the heat exchanger 20. If the electromagnet 1123 is directly exposed in the housing chamber, contact of the electromagnet 1123 with water vapor in the housing chamber may easily cause malfunction or damage of the electromagnet 1123. By disposing the electromagnet 1123 in the accommodating cavity 1125 of the seat body 1121, the seat body 1121 can block the water vapor outside the accommodating cavity 1125, so that the electromagnet 1123 can work normally and has a long service life.

In one embodiment, the operating assembly 13 further includes a reset member 136, and the reset member 136 is connected between the operating base 132 and the operating member 134. When the defrosting structure 10 is in a pending state, the operating member 134 slides and separates from the defrosting base 112 by the restoring force provided by the restoring member 136. When the defrosting structure 10 is switched to a pending state, the electromagnet 1123 is de-energized, and the operating member 134 can be separated from the defrosting base 112 by the reset member 136. The reset member 136 is provided to allow the operating member 134 to be automatically separated from the defrosting base 112, thereby providing excellent convenience in separation. In addition, the energy consumption of the defrosting structure 10 is also realized because the resetting piece 136 does not consume energy when being reset.

Of course, the reset mode of the operation member 134 is not limited to the above one. In other embodiments, when the defrost structure 10 is pending, a reverse current may also be applied to the electromagnet 1123 to allow the operating member 134 to disengage from the defrost base 112 under the repulsive force applied by the electromagnet 1123.

In the air conditioner 1 and the defrosting structure 10 thereof, the defrosting structure 10 and the heat exchanger 20 are all arranged in the casing of the air conditioner 1, when frost is formed on the heat exchanger 20, the defrosting structure 10 is switched to the defrosting state, the natural frequency of the defrosting structure 10 in the defrosting state is the same as the vibration frequency of the assembly equipment in the operation process, and therefore, the defrosting structure 10 and the assembly equipment resonate and swing back and forth. During the swing of the defrosting structure 10, the defrosting structure 10 continuously taps the heat exchanger 20 to defrost the heat exchanger 20. When the defrosting structure 10 completes defrosting, the defrosting structure 10 is switched to a pending state, at this time, the natural frequency of the defrosting structure 10 is different from the vibration frequency during the operation of the assembly equipment, and the defrosting structure 10 stops defrosting the heat exchanger 20. It can be seen that the air conditioner 1 and the defrosting structure 10 thereof provided in the present application perform defrosting only by using vibration during the operation of the assembly equipment, thereby enabling the air conditioner 1 to have a good heating performance.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
