Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a mobile air conditioner and a control method thereof. Background Art

[0002] At present, for the common mobile air conditioners on the market, their bodies are all located indoors. Whether they are used in the living room, bedroom or kitchen, an additional exhaust pipe must be connected to the outside. The exhaust pipe is retractable and will not exceed 170cm in length. Its function is to discharge the heat generated by the body to the outside through the lower fan to ensure the safe and reliable operation of the entire system. However, since the mobile air conditioner can be moved at will, users often encounter situations in which the mobile air conditioner is not connected to the exhaust pipe during operation due to insufficient exhaust pipe length or no doors or windows in the room. Instead, it is placed directly in the corner for operation. As a result, when the mobile air conditioner is running in cooling mode, the heat generated by the lower air outlet cannot be discharged to the outside through the exhaust pipe, but is blocked by the wall and blown back to the inside of the body. This situation will seriously affect the ambient temperature sampling, resulting in a low indoor temperature, but a high ambient temperature displayed on the display panel, which is very likely to cause customer complaints and poor user experience. At the same time, the high temperature inside the body also reduces the safety of the entire system. Summary of the invention

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0028] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] The air conditioner of the present invention performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

[0031] The compressor compresses the refrigerant gas in a high temperature and high pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0032] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0033] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0034] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0035] In the present invention, when the air conditioner is in heating operation, the high-temperature and high-pressure refrigerant discharged from the compressor flows into the condenser. At this time, the condenser functions as a radiator. Therefore, the refrigerant heats the indoor air by heat exchange with the indoor air as it flows in the condenser, and dissipates heat by itself and is cooled. The low-temperature and high-pressure refrigerant whose temperature is taken away by the condenser is decompressed by the expansion valve and changed into a low-temperature and low-pressure refrigerant. The refrigerant that flows into the evaporator through the expansion valve is heated by heat exchange with the outdoor air. Then, mainly the low-temperature gas refrigerant is sucked into the compressor from the evaporator via the accumulator.

[0036] Reference below Figure 1-Figure 7 A mobile air conditioner and a control method thereof according to an embodiment of the present invention are described.

[0037] Figure 1 Schematic diagram of the structure of a mobile air conditioner according to an embodiment of the present invention. Figure 1 As shown, a mobile air conditioner includes: a movable body, a refrigerant circulation loop arranged in the body, a compressor arranged in the body, a first temperature sensor, a second temperature sensor, a downwinder, an air outlet, a distance detection component, a display panel, and a controller. The refrigerant circulation loop allows the refrigerant to circulate in a loop composed of a compressor, a condenser, an expansion valve, an evaporator, a four-way valve, and a pressure reducer; the compressor is used to compress low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure refrigerant gas and discharge it to the condenser; the first temperature sensor is used to obtain the indoor ambient temperature; the second temperature sensor is used to obtain the temperature of the condenser; the downwinder is arranged in the body and is used to adjust the temperature of the condenser; an air outlet is arranged on one side of the body, and the air outlet is arranged opposite to the downwinder, and the downwinder discharges the heat generated by the operation of the mobile air conditioner to the outside of the body through the air outlet; the distance detection component is arranged in the body and is used to detect the distance between the air outlet and an obstacle located in the wind direction of the air outlet; the display panel is arranged on the body and is used to display the indoor ambient temperature; as shown in FIG. Figure 2 As shown, the controller is configured to: determine whether the operating state of the mobile air conditioner, the operating state of the compressor and the connection state of the air outlet and the exhaust pipe meet the temperature update and control conditions; when it is determined that the temperature update and control conditions are met, determine whether the distance detected by the distance detection component is greater than the preset distance; when the distance is greater than the preset distance, send the current indoor ambient temperature obtained by the first temperature sensor to the display panel to update the display temperature of the display panel; when the distance is less than or equal to the preset distance, control the compressor and the downwinder according to the operating state of the compressor and the temperature of the condenser, and update the display temperature of the display panel.

[0038] Specifically, the operating state of the mobile air conditioner includes cooling or heating operation, etc. When in cooling operation, the compressor is turned on, and the air outlet of the mobile air conditioner will discharge heat to ensure the normal operation of the mobile air conditioner. If the heat from the air outlet cannot be discharged normally, it will cause the internal temperature of the body to be too high, and the temperature displayed on the display panel will also be too high. At the same time, the risk of damage to the components inside the body is also relatively high. The connection state between the air outlet and the exhaust pipe includes two states: connected and unconnected. The buckle switch is located at the interface between the exhaust pipe and the card slot on the back of the mobile air conditioner. When the buckle switch is pressed, the air outlet and the exhaust pipe are in a connected state. When the buckle switch is not pressed, the air outlet and the exhaust pipe are not in a connected state. When the air outlet is not connected to the exhaust pipe, the mobile air conditioner is running in cooling mode, and the compressor is turned on, the distance detection component is used to detect the distance between the air outlet and the obstacle located in the wind direction of the air outlet. When the distance is greater than a preset distance, such as 1 meter, it is considered that the distance between the mobile air conditioner and the obstacle is far, and the heat from the air outlet of the mobile air conditioner can be smoothly discharged to the outside of the mobile air conditioner. The air outlet will not generate return air, thereby not affecting the display temperature of the display panel and not causing the internal temperature of the machine body to be too high. The current indoor ambient temperature can be directly obtained through the first temperature sensor and the display temperature of the display panel can be updated; when the distance is less than or equal to a preset distance, such as 1 meter, it is considered that the mobile air conditioner is Due to the close distance to the obstacle, the heat from the air outlet of the mobile air conditioner cannot be smoothly discharged to the outside of the mobile air conditioner, resulting in the undischarged heat entering the air inlet for the second time, thus forming a vicious circle. The current of the whole machine continues to increase, which brings serious safety hazards to the operation of the mobile air conditioner. In severe cases, there is a risk of fire. At this time, it is necessary to control the compressor and the downwinder according to the operating status of the compressor and the temperature of the condenser, and update the displayed temperature to avoid the temperature displayed on the display panel from getting higher and higher. At the same time, prevent the internal components of the mobile air conditioner from being damaged due to the influence of the continuous high temperature of the body, improve the reliability of the operation of high-power devices, extend their service life, and thus enhance the user experience.

[0039] In a specific embodiment, the distance detection component can use an infrared distance sensor. The infrared distance sensor is a sensing device with a pair of infrared signal transmitting and receiving diodes. When the infrared signal transmitting diode emits a beam of infrared light, a reflection process will be formed after irradiating an object. Its reflected signal is received by the infrared signal receiving diode. The distance between the distance detection component and the object can be calculated using the time difference between the emission and reception. Therefore, the distance detection component can be set on the mobile air conditioner to detect the distance between the mobile air conditioner and the obstacle. Exemplarily, the distance detection component can be set on the upper side of the downwinder outlet to detect the distance between the mobile air conditioner outlet and the obstacle when the outlet and the exhaust pipe are not in a connected state, so as to determine whether to control the compressor and the downwinder according to the operating state of the compressor and the temperature of the condenser, and update the display temperature of the display panel. Exemplarily, the display panel can include a digital tube, that is, the indoor temperature is displayed by the digital tube.

[0040] In one embodiment of the present invention, Figure 3 As shown, when the compressor and the down fan are controlled according to the operating status of the compressor and the temperature of the condenser, and the displayed temperature of the display panel is updated, the controller is specifically configured as follows: when the continuous on time of the compressor reaches a first preset time, the compressor is controlled to stop, the down fan is controlled to run at a first preset speed, and after a delay of a second preset time, the current indoor ambient temperature is sent to the display panel to update the displayed temperature of the display panel; when the continuous on time of the compressor does not reach the first preset time, the compressor and the down fan are controlled according to the temperature of the condenser, and the displayed temperature of the display panel is updated, wherein the first preset time is greater than the second preset time.

[0041] Specifically, when the air outlet and the exhaust pipe are not connected, the mobile air conditioner is running in cooling mode, the compressor is turned on, and the distance detection component detects that the distance between the obstacle located in the wind direction of the air outlet and the air outlet is less than the preset distance, if the continuous start time of the compressor reaches a first preset time, for example, 10 minutes, it is considered that the mobile air conditioner has generated a lot of heat and cannot be discharged smoothly through the air outlet. At this time, the compressor is controlled to stop, and the downwind fan is controlled to run at a first preset speed to completely dissipate the heat from the back of the body and the wall. That is, the heat from the air outlet of the mobile air conditioner is completely dissipated to the outside of the body as the downwind fan runs, so as to reduce the influence of the body heat on the first temperature sensor and the body temperature, and After a delay of a second preset time, for example 45 seconds, the display temperature of the display panel is updated; if the continuous opening time of the compressor does not reach the first preset time, if the temperature of the condenser is too high, the heat inside the body will increase rapidly, affecting the safe operation of the mobile air conditioner and the display temperature of the display panel. At this time, it is necessary to detect the temperature of the condenser through a second temperature sensor, control the compressor and the downwinder according to the temperature of the condenser, and update the display temperature of the display panel to avoid the temperature displayed on the display panel getting higher and higher, and at the same time prevent the mobile air conditioner from being damaged due to the influence of the continuous high temperature of the body, thereby improving the reliability of the operation of high-power devices and extending their service life, thereby improving the user experience.

[0042] It should be noted that the first preset time can be set periodically, for example, once every 10 minutes, that is, 10 minutes, 20 minutes, 30 minutes, etc. Then, when the continuous opening time of the compressor reaches 10 minutes, 20 minutes, 30 minutes, the compressor is controlled to stop, and the downwind fan is controlled to run at the first preset speed, and after a delay of the second preset time, the current indoor ambient temperature is sent to the display panel to update the displayed temperature of the display panel, so as to reduce the influence of the body heat on the first temperature sensor and the body temperature, avoid the temperature displayed on the display panel from getting higher and higher, and at the same time prevent the mobile air conditioner from being damaged by the influence of the continuous high temperature of the body.

[0043] In one embodiment of the present invention, Figure 4As shown, when the compressor and the downwind fan are controlled according to the temperature of the condenser and the display temperature of the display panel is updated, the controller is specifically configured as follows: when the temperature of the condenser reaches the first preset temperature, the compressor is controlled to stop, and the downwind fan is controlled to run at the second preset speed, until the temperature of the condenser drops to the second preset temperature, the current indoor ambient temperature is sent to the display panel to update the display temperature of the display panel, and the compressor is controlled to start, and the downwind fan is controlled to run at the first preset speed, wherein the first preset temperature is greater than the second preset temperature, and the second preset speed is greater than the first preset speed; when the temperature of the condenser does not reach the first preset temperature, the compressor is controlled not to stop, and the downwind fan is controlled to run at the first preset speed, and the current indoor ambient temperature is sent to the display panel to update the display temperature of the display panel. Specifically, the second preset speed is configured as the maximum rated speed of the downwind fan.

[0044] Specifically, if the continuous on time of the compressor does not reach the first preset time, such as 10 minutes, the temperature of the condenser plays a dominant role in the influence on the first temperature sensor and the body temperature. When the temperature of the condenser reaches the first preset temperature, such as 70°C, the compressor is controlled to stop, and the downwind fan is controlled to run at the second preset speed. Under the operation of the downwind fan, the mobile air conditioner quickly dissipates heat. When the temperature of the condenser drops to the second preset temperature, such as 40°C, it is considered that the temperature of the condenser has little effect on the first temperature sensor and the body temperature, and the safe operation of the body can be guaranteed. At this time, the indoor ambient temperature is sent to the display panel for display, and the compressor is controlled to start, and the downwind fan is controlled to run at the first preset speed, that is, the mobile air conditioner is controlled to operate normally; when the temperature of the condenser does not reach the first preset temperature, such as 70°C, it is considered that the heat inside the body will not increase rapidly, and there is no need to control the compressor to stop, and the downwind fan can be controlled to run at the first preset speed. It should be noted that when the temperature of the condenser reaches the first preset temperature, in order to achieve rapid heat dissipation of the mobile air conditioner body, after controlling the compressor to stop, the second preset speed of the downwind fan is configured as the maximum rated speed of the downwind fan, so that when the downwind fan is running, the body of the mobile air conditioner can achieve rapid heat dissipation, prevent the rapid increase of heat inside the body, and ensure the safe operation of the mobile air conditioner.

[0045] In one embodiment of the present invention, Figure 5 As shown, after controlling the compressor to stop and sending the current indoor ambient temperature to the display panel after a delay of a second preset time to update the displayed temperature of the display panel, the controller is also configured to: after a delay of a third preset time, control the compressor to start.

[0046] Specifically, the third preset time is delayed to accurately display the current ambient temperature, that is, after the display temperature of the display panel is updated within the third preset time, the compressor is controlled to start. Exemplarily, the third preset time is, for example, 15 seconds, then the display temperature of the display panel is updated within 15 seconds, and the compressor is controlled to start.

[0047] In one embodiment of the present invention, the controller is further configured to: when it is determined that the temperature update and control conditions are not met, send the current indoor ambient temperature to the display panel to update the display temperature of the display panel.

[0048] Specifically, when the mobile air conditioner is not in the cooling operation state, or the air outlet is in the connected state with the exhaust pipe, or the compressor is not in the on state, it is judged that the temperature update and control conditions are not met, that is, the air outlet of the mobile air conditioner can discharge heat smoothly, the internal temperature of the body will not be too high, the temperature displayed on the display panel will not be too high, and the risk of damage to the components inside the body is not great. The mobile air conditioner can operate normally. At this time, there is no need to control the compressor and the downwinder according to the operating status of the compressor and the temperature of the condenser. The current indoor temperature collected by the first temperature sensor can be sent to the display panel for updating.

[0049] In one embodiment of the present invention, the controller is specifically configured to: when the mobile air conditioner is in a cooling operation state, the air outlet and the exhaust pipe are not in a connected state, and the compressor is in an on state, determine that the temperature update and control conditions are met.

[0050] Specifically, when the mobile air conditioner is in the cooling operation state, the air outlet and the exhaust pipe are not connected, and the compressor is in the on state, it is determined that the temperature update and control conditions are met. At this time, when the distance detection component detects that the distance between the obstacle located in the wind direction of the air outlet and the air outlet is less than the preset distance, the operating state of the compressor and the temperature of the condenser will have a greater impact on the first temperature sensor and the body temperature. It is necessary to control the compressor and the downwind fan according to the operating state of the compressor and the temperature of the condenser to update the display temperature of the display panel and ensure the normal operation of the mobile air conditioner.

[0051] In one embodiment of the present invention, Figure 6 As shown, the controller is specifically configured to: when it is detected that the exhaust pipe is connected to the air outlet and the buckle switch of the exhaust pipe is closed

[0052] When the air outlet is connected to the exhaust pipe, it is determined that the air outlet and the exhaust pipe are in a connected state; otherwise, it is determined that the air outlet and the exhaust pipe are not in a connected state.

[0053] Specifically, the snap switch is located at the interface between the exhaust pipe and the card slot on the back of the mobile air conditioner. A physical switch is placed at the card slot slide. When the switch is pressed, the air outlet and the exhaust pipe are in a connected state, and the heat generated by the mobile air conditioner can be discharged smoothly through the exhaust pipe; when the switch is not pressed, it means that the exhaust pipe is not connected to the mobile air conditioner, and it is necessary to determine whether it is necessary to control the compressor and the downwinder according to the operating status of the compressor and the temperature of the condenser based on the distance between the air outlet of the mobile air conditioner and the obstacle located in the wind direction of the air outlet, so as to avoid the temperature displayed on the display panel becoming higher and higher, and at the same time prevent the internal components of the mobile air conditioner from being damaged due to the influence of the continuous high temperature of the body, thereby improving the reliability of the operation of high-power devices and extending their service life, thereby improving the user experience.

[0054] In one embodiment of the present invention, the controller is specifically configured to determine whether the snap switch is closed by detecting the pin level of the snap switch.

[0055] Specifically, the pin of the buckle switch is connected to the controller of the mobile air conditioner, and whether the buckle switch is closed is determined by detecting the pin level. Exemplarily, when the buckle switch is pressed, its pin level is low, and when the buckle switch is not pressed, its pin level is high; it can also be that when the buckle switch is pressed, its pin level is high, and when the buckle switch is not pressed, its pin level is low, which is related to the specific circuit design and will not be described here.

[0056] According to the mobile air conditioner of the embodiment of the present invention, by judging whether the operating state of the mobile air conditioner, the operating state of the compressor and the connection state of the air outlet and the exhaust pipe meet the temperature update and control conditions, and judging whether the distance detected by the distance detection component is greater than the preset distance, it is determined whether to control the compressor and the downwind fan according to the operating state of the compressor and the temperature of the condenser, and the display temperature of the display panel is updated. This can avoid the temperature displayed on the display panel being too high, and at the same time prevent the internal components of the mobile air conditioner from being damaged due to the influence of the continuous high temperature of the body, thereby improving the reliability of the operation of high-power devices and extending their service life, thereby improving the user experience.

[0057] A further embodiment of the present invention also discloses a control method for a mobile air conditioner. Figure 7 FIG. 1 is a flow chart of a control method of a mobile air conditioner according to an embodiment of the present invention. Figure 7 As shown, a control method of a mobile air conditioner is used for the mobile air conditioner as described in any of the above embodiments, and the method comprises the following steps:

[0058] Step S1: Determine whether the operating state of the mobile air conditioner, the operating state of the compressor, and the connection state between the air outlet and the exhaust pipe meet the temperature update and control conditions.

[0059] Step S2: When it is determined that the temperature update and control conditions are met, determine whether the distance detected by the distance detection component is greater than a preset distance.
