Description

[0002] In summer or winter, the dependence on air conditioners is generally increasing, but most users can only use air conditioners at home. Such home air conditioners cannot be moved and carried at any time like fans, which is very inconvenient for outdoor scenes (such as camping in the wild, temporary residence).

[0003] Therefore, portable air conditioners have emerged, but the existing portable air conditioners generally have single functions, only having cooling, heating or air supply modes, which leads to the fact that the existing portable air conditioners cannot meet the needs of users. For example, in a small and closed space such as a tent, the content of carbon dioxide or other toxic and harmful gases in the air will continue to accumulate. When a person is resting or sleeping, the human body perception is relatively weak, and these harmful gases are easy to cause harm to the human body. However, the existing portable air conditioners do not have a fresh air function, so that the indoor air cannot be purified. SUMMARY

[0066] Please refer to Figure 1 and Figure 2 , the embodiment of the present application provides a portable mobile air conditioner with fresh air function, comprising: a shell 1 and a compressor 2, a condenser assembly 3 and an evaporator assembly 4 arranged in the shell 1; the shell 1 further comprises: a first air inlet assembly 5, the first air inlet assembly 5 comprises a first air inlet 51 and a first air outlet 52 (as shown in combination Figure 3 ), the first air inlet 51 is communicated with the outside world; a second air inlet assembly 6, the second air inlet assembly 6 comprises a second air inlet 61 and a second air outlet 62 (as shown in combination Figure 4 ), the second air inlet 61 is communicated with the first air outlet 52, and the second air outlet 62 is communicated with the evaporator assembly 4; wherein the first air outlet 52 and the second air inlet 61 are provided with a first air door assembly 521 which can be opened or closed.

[0067] In the embodiment, when the air conditioner is in fresh air mode, the first air door assembly 521 is opened, air enters the shell 1 from the outside world, and the air enters the first air inlet 51 and the first air outlet 52 of the first air inlet assembly 5, the second air inlet 61 and the second air outlet 62 of the second air inlet assembly 6 in turn, and finally enters the evaporator assembly 4 from the second air outlet 62, thereby forming a fresh air duct in the shell 1 to realize air purification.

[0068] In an embodiment, as shown in Figure 3 , the first air inlet assembly 5 further comprises a third air outlet 53, and the third air outlet 53 is communicated with the condenser assembly 3.

[0069] In the embodiment, when the air conditioner is in cooling mode, the first air door assembly 521 is closed, air cannot enter other air conditioner assemblies from the first air outlet 52, at this time the third air outlet 53 is provided and communicated with the condenser assembly 3, when air enters the shell 1 from the outside world, the air enters the first air inlet 51 and the third air outlet 53 in turn, and finally enters the condenser assembly 3, thereby forming a cooling air duct in the shell 1 to realize air heat dissipation.

[0070] In an embodiment, as shown in Figure 4 , the second air inlet assembly 6 further comprises a third air inlet 63, the third air inlet 63 is communicated with the outside world, and the third air inlet 63 is provided with a second air door assembly 631 which can be opened or closed.

[0071] In this embodiment, when the air conditioner is in the air supply mode, the first air door assembly 521 is closed, air cannot enter other air conditioner assemblies from the first air outlet 52, the third air inlet 63 is set to communicate with the outside, and the second air door assembly 631 is opened, so that air directly enters the third air inlet 63 from the outside, then enters the second air outlet 62, and then enters the evaporator assembly 4, thereby forming an air supply air duct in the shell 1 to realize air supply. The air supply air duct has small air inlet resistance, large air volume, and low noise.

[0072] In this embodiment, the portable mobile air conditioner further includes a bottom shell 9, and the bottom shell 9 and the shell 1 jointly constitute an entire machine shell. Figure 5 and Figure 6 As shown in and

[0073] In an embodiment, as shown in Figure 1 and Figure 7 The evaporator assembly 4 includes at least one evaporator 41, an evaporator fan 42, and an enclosure assembly 43, and the evaporator 41, the evaporator fan 42, the enclosure assembly 43, and the second air inlet assembly 6 jointly form an evaporator end air inlet cavity 7, and the shell 1 is provided with an evaporator end air inlet 71 corresponding to the evaporator 41.

[0074] In this embodiment, the evaporator assembly 4 is arranged on the bottom shell 9 and forms the evaporator end air inlet cavity 7 in the shell 1, and two evaporators 41 are arranged in this embodiment, as shown in Figure 8 The shell 1 is provided with two evaporator end air inlets 71 corresponding to the two evaporators 41. In addition, the shell 1 is provided with an air supply mode air inlet 73 corresponding to the third air inlet 63, so that the shell 1 is provided with three evaporator end air inlets corresponding to the evaporator end, that is, two evaporator end air inlets 71 and one air supply mode air inlet 73. The three air inlets can be arranged on three sides of the shell 1 according to the positions of the evaporators 41 and the third air inlet 63. The shell 1 is further provided with an evaporator end air outlet 72 corresponding to the evaporator end, and air entering from the evaporator end air inlet 71 is finally output from the evaporator end air outlet 72.

[0075] As shown in Figure 7As shown, the enclosure component 43 includes a flow guide structure 431 and a baffle 432 disposed between the compressor 2 and the evaporator end air inlet cavity 7. The flow guide structure 431 separates the space formed by the two evaporators 41, the evaporator fan 42, the baffle 432, the second air inlet component 6, and the bottom shell 9 into the evaporator end air inlet cavity 7 and the compressor cavity, so that the two do not interfere with each other during operation. In the above embodiment, the two evaporators 41, the baffle 432, and the second air inlet component 6 form a rectangular layout, with the evaporator fan 42 and the bottom shell 9 located at the top and bottom, respectively, thus forming a cuboid-like cavity. That is, the evaporator fan 42 is a top-mounted fan, such as a top-mounted centrifugal fan, or the evaporator fan 42 can be placed at the bottom according to design requirements. The flow guide structure 431 divides the cavity into upper and lower parts, with the upper part being the evaporator end air inlet cavity 7 and the lower part being the compressor cavity. The airflow guiding structure 431 can be a hollow structure with a downward-facing opening. This hollow structure gradually expands from top to bottom, making the opening gradually larger. This airflow guiding structure can not only separate the compressor 2 from the evaporator end air inlet cavity 7, but also guide the air in the evaporator end air inlet cavity 7. In addition, the evaporator end air inlet cavity 7 also provides a sealed space for the evaporator 41, which plays a preliminary role in noise reduction.

[0076] In one embodiment, a filter structure 522 is provided between the first air outlet 52 and the second air inlet 61.

[0077] In this embodiment, as Figure 3 As shown, a filter structure 522 can be optionally installed at the first air outlet 52 or the second air inlet 61. When air enters sequentially from the outside through the first air inlet 51, the first air outlet 52, the second air inlet 61, and the second air outlet 62, the filter structure 522 filters the air, purifying the indoor air. The filter structure 522 can be a HEPA filter, which can be fixed between the first air outlet 52 and the second air inlet 61 using a HEPA filter bracket.

[0078] In one embodiment, the first damper assembly 521 includes a first drive mechanism 5211 and a first damper 5212 disposed between the first air outlet 52 and the second air inlet 61. The first drive mechanism 5211 drives the first damper 5212 and controls the opening and closing of the first damper 5212. The first damper 5212 can be installed at the position of the second air inlet 61 of the second air inlet assembly 6 or at the position of the first air outlet 52 of the first air inlet assembly 5.

[0079] The second damper assembly 631 comprises a second driving mechanism 6311 and a second damper 6312 arranged at the third air inlet 63, the second driving mechanism 6311 is drivingly connected to the second damper 6312, and is used for controlling opening and closing of the second damper 6312.

[0080] In the embodiment, the air conditioner has three modes, i.e., a refrigeration mode, an air supply mode and a fresh air mode, the opening and closing of the first damper 5212 and the second damper 6312 are adjusted by two driving mechanisms respectively, so that the air conditioner is in different modes, and automatic mode switching is realized in the subsequent implementation process, wherein the second damper 6312 can be in a translation form or a grating form, i.e., a grating 8 (the grating shape can refer to FIG. 8) is arranged at the second damper 6312, so as to facilitate opening and closing of the second damper 6312. Figure 1 The first damper 5212 can also be in a translation form or a grating form.

[0081] In an embodiment, the shell 1 is further provided with a carbon dioxide concentration sensor and a temperature sensor.

[0082] In the subsequent implementation process, the carbon dioxide concentration and the temperature are acquired by using the sensors, so as to detect the current carbon dioxide concentration and temperature in real time, and based on the real-time detection result, it is judged whether the mode needs to be switched.

[0083] The embodiment of the present application provides a control method of a portable mobile air conditioner with a fresh air function, comprising the following steps:

[0084] An instruction of entering a fresh air mode is received.

[0085] The compressor 2 is controlled to be closed, the condenser fan of the condenser assembly 3 is controlled to be closed, and the evaporator fan 42 of the evaporator assembly 4 is controlled to be opened.

[0086] The first damper assembly 521 is controlled to be opened, so that the second air inlet 61 is communicated with the first air outlet 52, and an air inlet passage in which air passes through the first air inlet 51, the first air outlet 52, the second air inlet 61 and the second air outlet 62 in sequence is formed.

[0087] The fresh air mode is entered.

[0088] In the embodiment, after the air conditioner receives the instruction of entering the fresh air mode, the compressor 2 and the condenser fan are closed, the evaporator fan 42 is opened, the first damper 5212 is controlled to be opened by the first driving mechanism 5211, the second damper 6312 is controlled to be closed by the second driving mechanism 6311, air from the outside enters the evaporator end air inlet cavity 7 through the first air inlet 51, the first air outlet 52, the second air inlet 61 and the second air outlet 62, and is sent to the indoor after being fully mixed with the air at the indoor evaporating end, so as to realize air exchange and purify the indoor air. The air inlet passage in the fresh air mode is shown in Figure 9 .

[0089] The first air inlet assembly 5 further comprises a third air outlet 53 which is communicated with the condenser assembly 3, and the control method further comprises the following steps:

[0090] receiving an instruction of entering the refrigeration mode;

[0091] controlling to open the compressor 2, the condenser fan of the condenser assembly 3 and the evaporator fan 42 of the evaporator assembly 4;

[0092] controlling to close the first damper assembly 521 so that the second air inlet 61 is separated from the first air outlet 52, and an air inlet passage in which air passes through the first air inlet 51 and the third air outlet 53 in sequence is formed;

[0093] entering the refrigeration mode.

[0094] In the embodiment, after the air conditioner receives the instruction of entering the refrigeration mode, the compressor 2, the condenser fan and the evaporator fan 42 are opened, and the first damper 5212 and the second damper 6312 are controlled to be closed by the first driving mechanism 5211 and the second driving mechanism 6311 respectively. Air from the outside enters the condenser assembly 3 through the first air inlet 51 and the third air outlet 53, so as to realize heat dissipation. The air inlet passage in the refrigeration mode is shown in Figure 10 . It should be noted that, because the first damper 5212 and the second damper 6312 are closed, air does not enter the fresh air duct, so the evaporator fan 42 can only pass air from the evaporator 41 (i.e. enter the evaporator through the evaporator end air inlet 71).

[0095] The second air inlet assembly 6 further comprises a third air inlet 63 which is communicated with the outside, and the third air inlet 63 is provided with a second damper assembly 631 which can be opened or closed. The control method further comprises the following steps:

[0096] receiving an instruction of entering the air supply mode;

[0097] controlling to close the compressor 2, close the condenser fan of the condenser assembly 3 and open the evaporator fan 42 of the evaporator assembly 4;

[0098] controlling to close the first air door assembly 521, separate the second air inlet 61 from the first air outlet 52 and open the second air door assembly 631 to form an air inlet path of air passing through the third air inlet 63 and the second air outlet 62 in turn;

[0099] entering the air supply mode.

[0100] In the embodiment, after the air conditioner receives the instruction to enter the air supply mode, the compressor 2 and the condenser fan are closed, the evaporator fan 42 is opened, the first air door 5212 is controlled to be closed by the first driving mechanism 5211, at this time, the evaporator 41 does not have heat exchange function and only has ventilation function, in order to increase the air inlet amount, the second air door 6312 is controlled to be opened by the second driving mechanism 6311, air directly enters the third air inlet 63 from the outside through the second air door 6312 and enters the evaporator end air inlet cavity 7 through the second air outlet 62, so as to improve the air inlet amount, and the air inlet path in the air supply mode is as shown in Figure 11 It should be noted that in the current mode, air does not need to pass through the evaporator 41, enters the second air inlet assembly 6 from the outside through the second air door 6312 and then enters the evaporator fan 42, the air inlet path has small air resistance, large air amount and low noise. If the third air inlet 63 is not arranged, air will pass through the evaporator 41 and then enter the evaporator fan 42, which will reduce the air amount and increase the air resistance. The state diagrams of the components in the three modes are as shown in Figure 12 .

[0101] As can be seen from the state diagrams of the components in the three modes, the compressor 2 only works in the refrigeration mode. In the fresh air mode and the air supply mode, the compressor 2 is closed. The purpose of closing the compressor 2 is to prevent air from passing through the first air inlet assembly 5 in the fresh air mode, and the first air inlet assembly 5 is connected with the condenser assembly 3, so that the air passing through the condenser assembly 3 will be heat exchanged, if the compressor 2 is opened, the air will be heated and then enter the evaporator assembly 4 to be cooled again, which will cause energy waste. Similarly, in the air supply mode, if the compressor 2 is opened, the air of the evaporator assembly 4 mainly comes from the air supply mode air inlet 73, the air passing through the evaporator assembly 4 is greatly reduced, the heat exchange efficiency is low, and energy waste will also be caused.

[0102] The control method further comprises:

[0103] obtaining a carbon dioxide concentration;

[0104] comparing the current carbon dioxide concentration with a preset concentration value;

[0105] If the current carbon dioxide concentration is greater than the concentration preset value, an instruction to enter or maintain the fresh air mode is issued.

[0106] In this embodiment, the air conditioner has a refrigeration mode, a fresh air mode and a supply air mode. In order to improve the comfort and health of the air conditioner used in a small space, the following three mode switching control methods are provided: different concentration preset values are set for different modes, and the carbon dioxide concentration is obtained by a carbon dioxide concentration sensor. For example, for the refrigeration mode or the supply air mode, the concentration preset value is set to m1, and if the current carbon dioxide concentration is greater than m1, the fresh air mode is entered. For the fresh air mode, the concentration preset value is set to m2 to avoid frequent mode switching, and m1>m2. If the current carbon dioxide concentration is greater than m2, the fresh air mode is maintained, and the carbon dioxide concentration is identified again every t1 time to determine whether to switch the mode.

[0107] The control method further comprises:

[0108] If the current carbon dioxide concentration is less than or equal to the concentration preset value, the current temperature is obtained.

[0109] The current temperature is compared with a temperature preset value.

[0110] If the current temperature is less than the temperature preset value, an instruction to enter the supply air mode or an instruction to stop is issued.

[0111] If the current temperature is greater than the temperature preset value, an instruction to enter the refrigeration mode is issued.

[0112] In this embodiment, if the current carbon dioxide concentration is less than or equal to the concentration preset value (i.e. m1 and m2), the current temperature is obtained by a temperature sensor. Different temperature preset values are set for different modes. For example, for the supply air mode or stop, the temperature preset value is set to T1 in advance, and if the current temperature is less than T1, the supply air mode or stop can be run according to user-defined, and the carbon dioxide concentration and temperature are detected again every t2 time. If the current temperature is greater than T1, the refrigeration mode is run, and the carbon dioxide concentration is detected again every t3 time. For the fresh air or refrigeration mode, the temperature preset value is set to T0 in advance, and in order to avoid frequent mode switching, T1>T0. If the current temperature is less than T0, the supply air mode or stop can also be switched according to user-defined, and the carbon dioxide concentration and temperature are detected again every t2 time. If the current temperature is greater than T0, the refrigeration mode is run, and the carbon dioxide concentration is detected again every t3 time. The flow chart of automatic switching of the three modes is shown in Figure 13

[0113] ​Among them, about the above-mentioned t1, t2, t3 time, the three time can be set consistent, also can set not consistent, can be set according to specific demand specifically.
