Description

Technical Field

However, environmental factors such as humidity, temperature, and light intensity have a significant impact on plant growth. Therefore, indoor plants currently require users to invest considerable time and effort in their care, and demand substantial experience in plant cultivation, which greatly reduces users' confidence and success rate. Furthermore, plants are not always effective at regulating indoor air quality. For example, at night, plants respire more vigorously, producing more carbon dioxide, which is detrimental to users' health. Summary of the Invention

[0026] If the first temperature is less than the minimum endpoint of the preset temperature range, and the temperature difference between the second temperature and the first temperature is less than the first preset temperature value, then the indoor unit of the air conditioner is controlled to operate in the heating mode.

[0027] Optionally, the outer casing is provided with ventilation openings; and

[0028] The indoor unit of the air conditioner includes:

[0029] The housing has a first air inlet communicating with the accommodating space and isolated from the vent, a second air inlet communicating with the vent and isolated from the accommodating space, and at least one air outlet communicating with the accommodating space.

[0036] Optionally, the indoor unit of the air conditioner further includes a heat exchanger movably disposed within the casing; wherein

[0043] According to a second aspect of the present invention, the present invention also provides an air-conditioned room for plants, comprising:

[0044] The outer shell, which defines an internal storage space for accommodating plants, includes a main body with an entrance and a door for closing and / or opening the entrance;

[0045] A plant growth light is installed inside the housing;

[0046] A light intensity detection device is used to obtain the light intensity within the accommodating space;

[0047] An oxygen concentration detection device is used to acquire the oxygen concentration within the accommodating space; and

[0049] This invention provides a control method for an air-conditioned room for plants. The air-conditioned room has an outer shell and a plant growth lamp disposed within the outer shell. The outer shell defines a storage space for placing plants; and the outer shell includes a main body and a door. Specifically, the air-conditioned room control method of this invention obtains the light intensity and oxygen concentration within the storage space, and controls the opening and closing of the door and the plant growth lamp based on these light intensity and oxygen concentration. On the one hand, the plant growth lamp can selectively supplement the storage space with light, thereby promoting photosynthesis and ensuring that the light intensity within the storage space is conducive to plant growth. On the other hand, the opening and closing of the door selectively connects the storage space with the indoor space where the air-conditioned room is located, thereby facilitating the targeted release of oxygen-rich gas from the storage space into the indoor space, improving the air-improving effect of the plants, and truly achieving the goal of improving indoor air quality and benefiting the health of users.

[0050] Furthermore, the present invention also obtains a first temperature within the containment space and a second temperature within the space where the air-conditioned room is located, and adjusts the operating mode of the indoor air-conditioned unit according to the first temperature and the second temperature when the first temperature within the containment space is not suitable for plant growth (beyond the preset temperature range), thereby making the temperature of the containment space more suitable for plant growth, reducing the user's effort, compensating for the user's lack of planting experience, and increasing the user's confidence and enjoyment in planting plants.

[0051] More importantly, the operating modes of the air conditioner indoor unit include not only the traditional cooling and heating modes, but also the natural air supply mode. In the natural air supply mode, the air conditioner indoor unit causes the airflow in the external space where the air-conditioned room is located to flow directly into the storage space without going through heat exchange, which cleverly utilizes the air environment outside the air-conditioned room and saves a lot of energy consumption in the air-conditioned room.

[0064] Figure 13 This is a schematic structural block diagram of an air-conditioned room according to an embodiment of the present invention. Detailed Implementation

[0065] This invention first provides a control method for an air-conditioned room for plants. Figure 1 and Figure 2 These are schematic structural diagrams of a plant-based air-conditioning chamber in different states according to an embodiment of the present invention. See also... Figure 1 and Figure 2 The air-conditioned room 1 includes an outer shell 10 defining a accommodating space 11, and a plant growth light 70 disposed within the outer shell 10. The outer shell 10 includes a main body 10a having an entrance 10a1 and a door 10b for closing and / or opening the entrance 10a1. Specifically, a plant shelf 80 may also be provided within the accommodating space 11 for placing plants.

[0066] The control method of the present invention is designed based on an air-conditioned room 1 having the above-described structure.

[0067] Figure 3 This is a schematic flowchart of a control method for a plant-based air-conditioning room according to an embodiment of the present invention. See also... Figure 3 The control method for the plant air-conditioning room of the present invention includes:

[0068] Step S10: Obtain the light intensity and oxygen concentration within the accommodating space 11; and

[0069] Step S20: Control the opening and closing of the door 10b and the plant growth lamp 70 based on the obtained light intensity and oxygen concentration.

[0070] The air-conditioned room control method of the present invention obtains the light intensity and oxygen concentration within the accommodating space 11, and controls the opening and closing of the door 10b and the plant growth lamp 70 based on these light intensity and oxygen concentration. On the one hand, the plant growth lamp 70 can selectively supplement the accommodating space 11 with light, thereby promoting plant photosynthesis and ensuring that the light intensity within the accommodating space 11 is conducive to plant growth. On the other hand, the opening and closing of the door 10b can selectively connect the accommodating space 11 with the indoor space where the air-conditioned room 1 is located, thereby facilitating the targeted release of oxygen-rich gas from the accommodating space 11 into the indoor space, improving the air-conditioning effect of the plants, and truly achieving the purpose of improving indoor air quality and benefiting the health of users.

[0071] In some embodiments, the steps of controlling the opening and closing of the door 10b and the opening and closing of the plant growth lamp 70 based on the obtained light intensity and oxygen concentration may specifically include:

[0072] If the light intensity is less than or equal to the first preset light intensity, then close door 10b;

[0073] If the oxygen concentration is less than or equal to the first preset concentration, turn on the plant growth light 70.

[0074] If the oxygen concentration is greater than the first preset concentration, then turn off the plant growth light 70.

[0075] When the light intensity in the accommodating space 11 is low, for example, less than or equal to the first preset light intensity, the plant respiration in the accommodating space 11 is strong, the photosynthesis is weak, and more carbon dioxide is produced. At this time, closing the door 10b can prevent a large amount of carbon dioxide from entering the indoor space where the air-conditioned room 1 is located, thereby avoiding the discomfort caused to users by excessively high carbon dioxide concentration in the indoor space.

[0076] When the light intensity in the accommodating space 11 is high, for example, greater than the first preset light intensity, the plants in the accommodating space 11 will have strong photosynthesis and produce more oxygen. At this time, the door 10b can be opened so that the oxygen produced by the plants in the accommodating space 11 can be discharged into the indoor space where the air-conditioned room 1 is located, which is beneficial to the user's health and improves the user's comfort experience.

[0077] When the oxygen concentration in the containment space 11 is low, for example, less than or equal to the first preset concentration, it indicates that the plant respiration in the containment space 11 is strong and photosynthesis is weak, which in turn indicates that the light intensity in the containment space 11 is weak. At this time, the plant growth lamp 70 can be turned on to supplement the light in the containment space 11, promote photosynthesis in the containment space 11, and thus promote plant growth.

[0078] When the oxygen concentration in the storage space 11 is high, for example, greater than the first preset concentration, it indicates that the photosynthesis of the plants in the storage space 11 is strong, which in turn indicates that the light intensity in the storage space 11 is strong. At this time, there is no need to supplement the light in the storage space 11, and the plant growth lamp 70 can be turned off.

[0079] Understandably, in a preferred embodiment, the light intensity within the accommodating space 11 can be determined first, and then the oxygen concentration within the accommodating space 11 can be determined.

[0080] Specifically, Figure 4 This is a schematic flowchart of a control method for a plant-based air-conditioned room according to another embodiment of the present invention. See also Figure 4 In one specific embodiment, the control method for the plant air-conditioning chamber of the present invention includes:

[0081] Step S10: Obtain the light intensity and oxygen concentration within the accommodating space 11; and

[0082] Step S21: Determine whether the light intensity is less than or equal to the first preset light intensity; if yes, proceed to step S22; if no, proceed to step S23.

[0083] Step S22, close door 10b;

[0084] Step S23, open door 10b;

[0085] Step S24: Determine whether the oxygen concentration is less than or equal to the first preset concentration; if yes, proceed to step S25; if no, proceed to step S26.

[0086] Step S25, turn on the plant growth light 70;

[0087] Step S26, turn off the plant growth light 70.

[0088] In some embodiments, the steps of controlling the opening and closing of the door 10b and the plant growth light 70 based on light intensity and oxygen concentration further include:

[0089] If the light intensity is greater than the first preset light intensity and less than or equal to the second preset light intensity, then open the door 10b and turn off the plant growth light 70.

[0090] If the light intensity is greater than the second preset light intensity and less than or equal to the third preset light intensity, then the door 10b and the plant growth light 70 will be turned off; and

[0091] If the light intensity is greater than the third preset light intensity, the door 10b and plant growth light 70 will be turned off, and a reminder message will be sent to the terminal device connected to the air-conditioned room to remind the plants in the accommodating space 11 to be shaded.

[0092] When the light intensity within the accommodating space 11 is high, the light intensity can be further subdivided. When the light intensity is between the first and second preset light intensities, the light intensity is suitable. In this case, the door 10b is opened to allow the oxygen produced by the plants to be released into the indoor space of the air-conditioned room 1, and the plant growth light 70 is turned off to save energy. When the light intensity is between the second and third preset light intensities, the light intensity is slightly high. In this case, the door 10b and the plant growth light 70 are closed, and the door 10b can be used to appropriately shade the accommodating space 11 to reduce the light intensity, which is beneficial to plant growth. When the light intensity is greater than the third preset light intensity, the light intensity is too strong and may cause sunburn or other damage to the plants. In this case, in addition to closing the door 10b and the plant growth light 70, a prompt message is sent to the terminal device connected to the air-conditioned room 1 to remind the user to shade the plants in the accommodating space 11, minimizing the possibility of sunburn.

[0093] In some embodiments, an indoor air conditioning unit 20 is provided within the accommodating space 11 to regulate the temperature environment within the accommodating space 11. In these embodiments, the control method of the present invention further includes:

[0094] Obtain the first temperature within the containment space 11 and the second temperature within the indoor space where the air-conditioned room 1 is located;

[0095] When the first temperature exceeds the preset temperature range, the operating mode of the indoor unit 20 of the air conditioner is adjusted according to the first temperature and the second temperature; wherein

[0096] The operating modes of the air conditioner indoor unit 20 include at least heating mode, cooling mode and natural air supply mode; in heating mode and cooling mode, the air conditioner indoor unit 20 causes the airflow inside the accommodating space 11 to flow into the accommodating space 11 after heat exchange; in natural air supply mode, the air conditioner indoor unit 20 causes the airflow in the external space where the air-conditioned room 1 is located to flow directly into the accommodating space 11.

[0097] The air conditioning room control method of the present invention obtains a first temperature in the accommodating space 11 and a second temperature in the space where the air conditioning room 1 is located. When the first temperature in the accommodating space 11 exceeds the preset temperature range, it indicates that the temperature in the accommodating space 11 is not suitable for plant growth. At this time, the operating mode of the indoor unit 20 of the air conditioner can be adjusted according to the magnitude of the first temperature and the second temperature and the relationship between the two, so that the temperature of the accommodating space 11 is more suitable for plant growth, reducing the user's effort, making up for the user's lack of planting experience, and increasing the user's confidence and enjoyment in planting plants.

[0098] More importantly, the operating modes of the indoor unit 20 include not only the traditional cooling and heating modes, but also a natural air supply mode. In the natural air supply mode, the indoor unit 20 causes the airflow in the external space where the air-conditioned room 1 is located to flow directly into the accommodating space 11 without going through heat exchange, which cleverly utilizes the air environment outside the air-conditioned room 1, greatly saving the energy consumption of the air-conditioned room 1 and reducing the cost of planting plants for users.

[0099] Figure 5 This is a schematic flowchart of a control method for a plant-based air-conditioning room according to yet another embodiment of the present invention. See also... Figure 5 In one specific embodiment, the control method for the plant air-conditioning chamber of the present invention includes:

[0100] Step S10: Obtain the light intensity and oxygen concentration within the accommodating space 11; and

[0101] Step S20: Control the opening and closing of the door 10b and the plant growth lamp 70 based on the obtained light intensity and oxygen concentration.

[0102] Step S30: Obtain the first temperature in the accommodating space 11 and the second temperature in the space where the air-conditioned room 1 is located;

[0103] Step S40: Determine whether the first temperature is within the preset temperature range; if yes, return to step S10; if no, proceed to step S50; and

[0104] Step S50: Adjust the operating mode of the indoor unit 20 of the air conditioner according to the first temperature and the second temperature.

[0105] In some embodiments, step S50 of adjusting the operating mode of the indoor unit 20 of the air conditioner according to the first temperature and the second temperature may specifically include:

[0106] If the first temperature is greater than the maximum endpoint of the preset temperature range, and the temperature difference between the first temperature and the second temperature is greater than or equal to the first preset temperature value, then the indoor unit 20 of the air conditioner is controlled to operate in natural ventilation mode.

[0107] If the first temperature is less than the minimum endpoint of the preset temperature range, and the temperature difference between the second temperature and the first temperature is greater than or equal to the first preset temperature value, then the indoor unit 20 of the air conditioner is controlled to operate in natural air supply mode.

[0108] If the first temperature is greater than the maximum endpoint of the preset temperature range, and the temperature difference between the first temperature and the second temperature is less than the first preset temperature value, then the indoor unit 20 of the air conditioner is controlled to operate in the cooling mode.

[0109] If the first temperature is less than the minimum endpoint of the preset temperature range, and the temperature difference between the second temperature and the first temperature is less than the first preset temperature value, then the indoor unit 20 of the air conditioner is controlled to operate in the heating mode.

[0110] Specifically, when the first temperature exceeds the maximum value of the preset temperature range, it indicates that the temperature inside the air-conditioned room 1 is too high, unsuitable for plant growth in the storage space 11. If, at this time, the first temperature is higher than the second temperature, and the temperature difference between the first and second temperatures is significant, it indicates that the temperature in the ambient space where the air-conditioned room 1 is located is relatively low. The air in this ambient space can be fully utilized to appropriately lower the temperature inside the storage space 11, making it more conducive to plant growth. Therefore, at this time, the indoor unit 20 operates in natural ventilation mode. Simply using the airflow drive device of the indoor unit 20 to deliver outside air into the storage space 11 is sufficient to effectively improve the temperature inside the storage space 11, without the need for heat exchange of this portion of air, thus effectively reducing the energy consumption of the indoor unit 20. Conversely, if the temperature difference between the first temperature and the second temperature is small, or even if the first temperature is lower than the second temperature, it indicates that the temperature in the ambient space where the air-conditioned room 1 is located is not much different from the temperature inside the air-conditioned room 1, or even higher than the temperature inside the air-conditioned room 1. In this case, controlling the indoor unit 20 of the air conditioner to operate in cooling mode can effectively reduce the temperature inside the ambient space 11, making it more conducive to plant growth.

[0111] When the first temperature is lower than the minimum threshold of the preset temperature range, it indicates that the temperature inside the air-conditioned room 1 is too low and unsuitable for plant growth in the storage space 11. If, at this time, the first temperature is lower than the second temperature, and the temperature difference between the two is significant, it indicates that the temperature in the environment of the air-conditioned room 1 is relatively high. The air in this environment can be fully utilized to appropriately raise the temperature inside the storage space 11, thus promoting plant growth. Therefore, the indoor unit 20 operates in natural ventilation mode at this time. Simply using the airflow drive device of the indoor unit 20 to deliver outside air into the storage space 11 effectively improves the temperature inside the storage space 11, eliminating the need for heat exchange and effectively reducing the energy consumption of the indoor unit 20. Conversely, if the temperature difference between the second temperature and the first temperature is small, or even if the first temperature is higher than the second temperature, it indicates that the temperature in the ambient space where the air-conditioned room 1 is located is not much different from the temperature inside the air-conditioned room 1, or even lower than the temperature inside the air-conditioned room 1. In this case, controlling the indoor unit 20 of the air conditioner to operate in heating mode is necessary to effectively raise the temperature inside the ambient space 11, making it more conducive to plant growth.

[0112] Specifically, Figure 6 This is a schematic flowchart illustrating how, according to an embodiment of the present invention, the operating mode of an indoor air conditioning unit is adjusted based on a first temperature and a second temperature. See also... Figure 6 The steps for adjusting the operating mode of the indoor unit 20 of the air conditioner according to the first temperature and the second temperature may specifically include:

[0113] Step S501: Determine whether the first temperature is greater than the maximum endpoint value of the preset temperature range; if yes, proceed to step S511; if no, proceed to step S521.

[0114] Step S511: Calculate the temperature difference between the first temperature and the second temperature;

[0115] Step S512: Determine whether the temperature difference between the first temperature and the second temperature is greater than or equal to the first preset temperature value; if yes, proceed to step S531; if no, proceed to step S532.

[0116] Step S531: Control the indoor unit of the air conditioner to operate in natural air supply mode;

[0117] Step S532: Control the indoor unit of the air conditioner to operate in cooling mode;

[0118] Step S521: Calculate the temperature difference between the second temperature and the first temperature;

[0119] Step S522: Determine whether the temperature difference between the second temperature and the first temperature is greater than or equal to the first preset temperature value; if yes, proceed to step S531; if no, proceed to step S533.

[0120] Step S533: Control the indoor unit of the air conditioner to operate in heating mode.

[0121] It is understandable that step S501 is performed on the premise that the first temperature is outside the preset temperature range. If the result of step S501 is negative, that is, the first temperature is less than the maximum endpoint of the preset temperature range, then the first temperature must be less than the minimum endpoint of the preset temperature range, and there is no need to compare the first temperature with the minimum endpoint of the preset temperature range.

[0122] It should be noted that step S501 can also compare whether the first temperature is greater than the minimum endpoint value of the preset temperature range. If so, the first temperature must be greater than the maximum endpoint value of the preset temperature range, and the other control logic remains unchanged.

Figure 9 yes Figure 7 A schematic enlarged view of part A in the middle. Figure 10 yes Figure 8 A schematic enlarged view of part B in the middle section. Figure 11 This is a schematic exploded view of an indoor air conditioning unit according to an embodiment of the present invention. In some embodiments, a vent 12 is provided on the housing 10. The vent 12 connects the accommodating space 11 inside the housing 10 and the ambient space where the housing 10 is located.

[0124] Furthermore, the indoor unit 20 of the air conditioner includes a casing 21, an airflow regulating mechanism 22, and an airflow driving device 24. The casing 21 has a first air inlet 211 communicating with the accommodating space 11 and isolated from the vent 12, a second air inlet 212 communicating with the vent 12 and isolated from the accommodating space 11, and at least one air outlet communicating with the accommodating space 11. That is, the first air inlet 211 communicates only with the accommodating space 11 and not with the vent 12, allowing only air from the accommodating space 11 to pass through and enter the casing 21. The second air inlet 212 communicates only with the vent 12 and not with the accommodating space 11, allowing only air from the indoor space where the outer casing 10 is located (i.e., the indoor space where the air-conditioned room 1 is located) to pass through and enter the casing 21. The number of air outlets can be one or more, and each air outlet is connected to the accommodating space 11 to discharge the air inside the casing 21 into the accommodating space 11.

[0125] An airflow drive device 24 is disposed inside the housing 21 and is used to drive the airflow in a controlled manner.

[0126] The airflow adjustment mechanism 22 is movably disposed within the housing 21 and has a first state in which the first air inlet 211 is open and the second air inlet 212 is blocked. Figure 10 The state shown), and the second state where the second air inlet 212 is open and the first air inlet 211 is blocked. Figure 9 (as shown in the figure) to adjust the airflow of the air-conditioned room 1 by switching the state of the airflow adjustment mechanism 22.

[0127] The indoor unit 20 of the air conditioner has two air inlets on its casing 21. The first air inlet 211 is connected to the accommodating space 11 and isolated from the vent 12 on the outer casing 10, while the second air inlet 212 is isolated from the accommodating space 11 and connected to the vent 12 on the outer casing 10. That is, the indoor unit 20 can allow air from the accommodating space 11 to enter through the first air inlet 211, and also allows air from outside the air-conditioned room 1 to enter through the second air inlet 212. Furthermore, the casing 21 is equipped with an airflow adjustment mechanism 22, which can adjust the opening and closing of the first air inlet 211 and the second air inlet 212 by switching its state.

[0128] Based on the air-conditioned room 1 with the above structure, the steps of controlling the indoor unit 20 of the air conditioner to operate in natural ventilation mode may specifically include:

[0129] Only the airflow drive device 24 is activated, and the airflow adjustment mechanism 22 is adjusted to its second state. That is, in the natural air supply mode, the compressor of the indoor unit 20 of the air conditioner does not start, no refrigerant flows through the heat exchanger of the indoor unit 20 of the air conditioner, and there is no heat exchange with the airflow flowing through it.

[0130] Based on the air-conditioned room 1 with the above structure, the steps of controlling the indoor unit 20 of the air conditioner to operate in heating mode or cooling mode may specifically include:

[0131] The airflow drive device 24 and the compressor of the indoor air conditioning unit 20 are started, and the airflow adjustment mechanism 22 is adjusted to the first state. That is, in both heating and cooling modes, the airflow drive device 24 and the compressor are started, so that refrigerant flows through the heat exchanger of the indoor air conditioning unit 20, thereby exchanging heat with the airflow flowing through the heat exchanger. It is understood that the refrigerant flow direction is different in heating and cooling modes. Since this technology is well known in the art, it will not be described in detail here.

[0132] In summary, in this embodiment, the switching of the operating mode of the indoor air conditioner 120 is achieved through the state switching of the air duct adjustment mechanism 22. This invention cleverly achieves the switching of the operating mode of the indoor air conditioner 120 by opening special first air inlets 211 and second air inlets 212 on the casing 21 and setting the air duct adjustment mechanism 22. The structure is very simple, and the state switching process of the air duct adjustment mechanism 22 is simple and easy to control.

[0133] In some embodiments, the airflow drive device 24 is a fan. Specifically, the airflow drive device 24 can be a cross-flow fan, an axial flow fan, or a centrifugal fan.

[0134] Furthermore, in natural ventilation mode, the fan speed is inversely related to the absolute value of the temperature difference between the first and second temperatures. That is, the greater the absolute value of the temperature difference between the first and second temperatures, the greater the temperature compensation that a unit volume of air from outside the air-conditioned room 1 can provide, and the lower the fan speed; conversely, the greater the absolute value of the temperature difference, the higher the fan speed.

[0135] Furthermore, in heating mode, the fan speed is inversely related to the first temperature. That is, the higher the first temperature, the less heat is required in the containment space 11, and the lower the fan speed; conversely, the lower the first temperature, the higher the fan speed.

[0136] Furthermore, in cooling mode, the fan speed is positively correlated with the first temperature. That is, the higher the first temperature, the more heat is required in the accommodating space 11, and the higher the fan speed; conversely, the lower the first temperature, the lower the fan speed.

[0137] In some embodiments, the indoor unit 20 of the air conditioner also includes a heat exchanger 23 movably disposed within the housing 21.

[0138] In these embodiments, when the indoor unit 20 of the air conditioner is operating in natural ventilation mode, the control method of the present invention further includes:

[0139] Adjust the heat exchanger 23 to be in the airflow path where the second air inlet 212 is located.

[0140] When the indoor unit 20 of the air conditioner is running in cooling mode or heating mode, the control method of the present invention further includes:

[0141] Adjust the heat exchanger 23 to be in the airflow path where the first air inlet 211 is located.

[0142] Specifically, Figure 12 This is a schematic flowchart illustrating the adjustment of the operating mode of the indoor unit of an air conditioner according to a first temperature and a second temperature, based on another embodiment of the present invention. In another specific embodiment, see... Figure 12 The steps for adjusting the operating mode of the indoor unit 20 of the air conditioner according to the first temperature and the second temperature may specifically include:

[0143] Step S501: Determine whether the first temperature is greater than the maximum endpoint value of the preset temperature range; if yes, proceed to step S511; if no, proceed to step S521.

[0144] Step S511: Calculate the temperature difference between the first temperature and the second temperature;

[0145] Step S512: Determine whether the temperature difference between the first temperature and the second temperature is greater than or equal to the first preset temperature value; if yes, proceed to step S531'; if no, proceed to step S532'.

[0146] Step S531': Control the indoor unit 20 of the air conditioner to operate in natural ventilation mode, and adjust the heat exchanger 23 to the airflow path where the second air inlet 212 is located;

[0147] Step S532': Control the indoor unit 20 of the air conditioner to operate in cooling mode, and adjust the heat exchanger 23 to the airflow path where the first air inlet 211 is located;

[0148] Step S521: Calculate the temperature difference between the second temperature and the first temperature;

[0149] Step S522: Determine whether the temperature difference between the second temperature and the first temperature is greater than or equal to the first preset temperature value; if yes, proceed to step S531'; if no, proceed to step S533'.

[0150] Step S533': Control the indoor unit 20 of the air conditioner to operate in heating mode, and adjust the heat exchanger 23 to the airflow path where the first air inlet 211 is located.

[0151] When the indoor unit 20 of the air conditioner is in heating mode or cooling mode, the air duct adjustment mechanism 22 is in its first state, the first air inlet 211 is open, and the second air inlet 212 is blocked. At this time, the heat exchanger 23 moves into the airflow path where the first air inlet 211 is located, so as to make full contact with the airflow entering the casing 21 from the first air inlet 211, thereby enabling this part of the airflow to fully exchange heat with the heat exchanger 23, improving the air conditioning effect of the air-conditioned room 1 when the air duct adjustment mechanism 22 is in its first state.

[0152] When the indoor unit 20 of the air conditioner is in natural air supply mode, and the airflow adjustment mechanism 22 is in its second state, the first air inlet 211 is blocked and the second air inlet 212 is open. At this time, the heat exchanger 23 moves into the airflow path where the second air inlet 212 is located, so as to make full contact with the airflow entering the casing 21 from the second air inlet 212. At this time, although the compressor of the indoor unit 20 of the air conditioner is not running, the heat exchanger 23 may still have a certain amount of residual heat or residual cooling capacity. Therefore, moving the heat exchanger 23 into the airflow path where the second air inlet 212 is located can make full use of this residual heat or residual cooling capacity. In addition, the heat exchanger 23 can also filter and purify the airflow entering the casing 21 from the second air inlet 212 to a certain extent, so as to improve the cleanliness of the airflow flowing into the accommodating space 11.

[0153] Preferably, the airflow regulating mechanism 22 and the heat exchanger 23 can be driven by the same drive device 25 so that they can rotate synchronously around the same axis.

[0154] In some embodiments, the at least one air outlet includes a first air outlet 213 disposed opposite to the first air inlet 211 and a second air outlet 214 disposed opposite to the second air inlet 212.

[0155] Furthermore, the airflow regulating mechanism 22 is configured to open the first air outlet 213 and block the second air outlet 214 in a first state, and open the second air outlet 214 and block the first air outlet 213 in a second state. That is, when the airflow regulating mechanism 22 is in the first state, the first air inlet 211 and the first air outlet 213 are open, and the second air inlet 212 and the second air outlet 214 are blocked. Air in the accommodating space 11 enters the casing 21 through the first air inlet 211 and flows out of the casing 21 through the first air outlet 213. When the airflow regulating mechanism 22 is in the second state, the first air inlet 211 and the first air outlet 213 are blocked, and the second air inlet 212 and the second air outlet 214 are open. Air in the indoor space where the air-conditioned room 1 is located enters the casing 21 through the second air inlet 212 and flows out of the casing 21 through the second air outlet 214. Since the first air inlet 211 and the first air outlet 213 are arranged opposite to each other, and the second air inlet 212 and the second air outlet 214 are arranged opposite to each other, the airflow adjustment mechanism 22 can ensure that the airflow inside the casing 21 flows in a straight direction without any change in flow direction, regardless of whether the airflow adjustment mechanism 22 is in the first state or the second state. This reduces the airflow resistance and increases the airflow speed.

[0156] In some embodiments, the housing 21 is cylindrical, and the first air inlet 211, the second air inlet 212, the first air outlet 213, and the second air outlet 214 are all formed on the side wall of the cylinder and are spaced apart along the circumference of the cylinder. That is, the first air inlet 211, the second air inlet 212, the first air outlet 213, and the second air outlet 214 are all arc-shaped air vents with the center of the cylinder as the center.

[0157] Furthermore, the airflow adjustment mechanism 22 includes two arc-shaped baffles 221 adapted to the shape of the side wall of the cylinder. When the airflow adjustment mechanism 22 is in its first state, the two arc-shaped baffles 221 respectively block the second air inlet 212 and the second air outlet 214, and when the airflow adjustment mechanism 22 is in its second state, they respectively block the first air inlet 211 and the first air outlet 213. This effectively prevents air in the flow path between the first air inlet 211 and the first air outlet 213 from flowing out of the housing 21 through the second air inlet 212 and the second air outlet 214, and also effectively prevents air in the flow path between the second air inlet 212 and the second air outlet 214 from flowing out of the housing 21 through the first air inlet 211 and the first air outlet 213, ensuring airflow under various conditions and improving the air quality within the accommodating space 11.

[0158] Since both the airflow regulating mechanism 22 and the heat exchanger 23 are rotatable, their rotation trajectories are circular or arc-shaped. Therefore, this invention sets the housing 21 as a cylinder, and places the first air inlet 211, the second air inlet 212, and the air outlet on the side wall of the cylinder. This ensures that the airflow regulating mechanism 22 maintains good shielding with either the first air inlet 211 or the second air inlet 212 after rotation. Furthermore, while ensuring smooth rotation of the airflow regulating mechanism 22 and the heat exchanger 23, the cylindrical housing 21 achieves the highest space utilization and occupies the least amount of space within the accommodating area, demonstrating a very ingenious design.

[0159] In some embodiments, the second air inlet 212 is disposed opposite to and spaced apart from the vent 12 to form a buffer space 13 between the second air inlet 212 and the vent 12. The other sides of the buffer space 13, except for the sides where the second air inlet 212 and the vent 12 are located, are isolated from the accommodating space 11 by a sealing plate 14.

[0160] The sealing plate 14 effectively separates the vent 12 from the other areas of the accommodating space 11 except for the buffer space 13 and the second air inlet 212, so that the outside air entering from the vent 12 can only flow into the buffer space 13 and then into the second air inlet 212.

[0161] The buffer space 13 serves two purposes: firstly, it provides a flow buffer for the air flowing into the air-conditioned room 1 from the vent 12, reducing the resistance encountered by the air and thus increasing the air intake volume of the vent 12; secondly, the buffer space 13 also provides a certain distance buffer, increasing the distance between the second air inlet 212 and the vent 12, preventing the heat or cold energy inside the indoor unit 20 from easily dissipating to the outside of the air-conditioned room 1 due to the close proximity of the second air inlet 212 and the vent 12. Furthermore, the buffer space 13 also provides a certain visual buffer, preventing users from directly looking at the indoor unit 20 through the vent 12, thus improving the aesthetic appearance of the air-conditioned room 1.

[0162] The present invention also includes an air-conditioned room for plants. Figure 13 This is a schematic structural block diagram of an air-conditioned room according to an embodiment of the present invention. The air-conditioned room 1 includes an outer shell 10, a plant growth lamp 70, a light intensity detection device 50, an oxygen concentration detection device 60, and a control device 90.

[0164] A plant growth light 70 is disposed within the housing 10 and is used to emit light into the accommodating space 11 in a controlled manner.

[0165] The light intensity detection device 50 is used to obtain the light intensity within the accommodating space 11.

[0166] The oxygen concentration detection device 60 is used to obtain the oxygen concentration in the accommodating space 11.

[0167] The control device 90 includes a processor 91 and a memory 92. The memory 92 stores a machine-executable program 93, and when the machine-executable program 93 is executed by the processor 91, it is used to implement the control method described in any of the above embodiments.

[0168] Specifically, the plant growth lamp 70, the light intensity detection device 50, and the oxygen concentration detection device 60 are all housed inside the outer casing 10 and are all connected to the control device 90 via signal.

[0169] Specifically, processor 91 can be a central processing unit (CPU), a digital processing unit, etc. Processor 91 sends and receives data via a communication interface. Memory 92 is used to store the program executed by processor 91. Memory 92 can be any medium capable of carrying or storing desired program code in the form of instructions or data structures, and accessible by a computer; it can also be a combination of multiple memories. The aforementioned machine-executable program 93 can be downloaded from a computer-readable storage medium to the corresponding computing / processing device or via a network (e.g., the Internet, local area network, wide area network, and / or wireless network) to a computer or external storage device.
