Description

Technical Field

[0001] The utility model relates to the technical field of home planting, in particular to a temperature and humidity control system of a full-environmentally controlled home planting machine. Background Art

[0002] Home cultivation technology is an emerging technology. Various environmental and nutritional controls need to be implemented throughout the plant cultivation process, including temperature and humidity, light intensity, water and fertilization to achieve better growth and development of vegetables.

[0003] Taking temperature and humidity control as an example, temperature and humidity control are two very important environmental factors in plant growth. However, existing home growers can generally only provide plant lighting and nutrient solution supply, etc., and the temperature and humidity cannot be controlled, resulting in poor plant growth and development when the temperature is high in summer, low in winter, or when there is a large temperature difference between day and night. Utility Model Content

[0004] The content of this utility model is used to introduce the concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this disclosure is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0005] Some embodiments of the present utility model provide a temperature and humidity control system for a fully environmentally controlled home grower to solve the technical problems mentioned in the above background technology section.

[0006] The temperature and humidity control system of the fully environmentally controlled home planting machine includes a ventilation component, wherein:

[0007] The ventilation assembly includes a channel body, a partition, an air inlet damper, an air outlet damper, a channel damper and a fan, wherein the partition divides the channel body into a first channel, a second channel, a top channel and a bottom channel that are connected along the width direction of the channel body; an air inlet damper and an air outlet damper are arranged at the upper and lower ends of the channel body; the first channel is connected to the cabinet; a channel damper is arranged in the second channel; the fan is arranged in the top channel; and a temperature control assembly for reducing the temperature in the cabinet is arranged in the bottom channel;

[0008] In response to the air inlet damper and the air outlet damper being opened, the channel damper is closed, and under the traction of the fan, the external air enters the cabinet through the air inlet damper and is discharged through the air outlet damper, completing the external circulation;

[0009] In response to the air inlet damper and the air outlet damper being closed, the channel damper is opened, and under the traction of the fan, the air in the cabinet passes through the first channel and the second channel to complete the internal circulation.

[0010] The above-mentioned embodiments of the utility model have the following beneficial effects: through the temperature and humidity control system of a fully environmentally controlled home planting machine of the utility model, it is possible to realize the external circulation of air from outside the cabinet to inside the cabinet and the internal circulation of air inside the cabinet, thereby realizing the control of temperature and humidity. Specifically, further, a channel damper is provided in the above-mentioned second channel. When the channel damper is closed, and the air inlet damper and the air outlet damper are opened, under the traction of the fan, the external air enters through the air inlet damper, flows through the bottom channel, and enters the first channel. Since the fan is arranged in the top channel, the fan can produce a suction effect on the first channel and the air in the cabinet, and all are discharged through the air outlet damper. In this way, the external circulation of the system is realized. Then, the temperature and humidity of the air in the cabinet can be adjusted by introducing external air.

[0011] When the channel damper is opened and the air inlet damper and the air outlet damper are closed, the air in the channel body circulates among the second channel, the bottom channel, the first channel and the top channel under the traction of the fan. Since the bottom channel is provided with a temperature control component, the air temperature can be adjusted by the temperature control component. In this process, the air in the channel body can enter the cabinet through the through hole, thereby realizing the internal circulation of the system, which not only adjusts the temperature and humidity of the air in the cabinet, but also makes the temperature and humidity of the air inside the cabinet more uniform.

[0020] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0021] First see Figure 1 , Figure 1 It is a cross-sectional view of an embodiment of a ventilation assembly of the present utility model. Figure 1 Shown is a side view of a home planter, right side ( Figure 1 The direction in the middle) is the front of the family planting machine, and the left side ( Figure 1The home planting machine may include a cabinet 1 and a multi-layer planting rack 2. The multi-layer planting rack 2 is placed in the cabinet 1 at intervals along the vertical direction. It should be noted that the number of the planting racks 2 is determined according to the height of the cabinet 1, and those skilled in the art can make corresponding adjustments. Figure 1 , taking the three-layer planting rack 2 as an example for explanation.

[0022] like Figure 1 As shown, the temperature and humidity control system of the home planting machine may include a ventilation component, which may be arranged at the rear or both sides of the cabinet 1. Those skilled in the art may adjust it according to actual conditions. Figure 1 Provide explanation.

[0023] The ventilation assembly includes a channel body 41, and a partition 42 is arranged in the channel body 41. Both sides of the partition 42 can be connected to the inner walls of both sides of the channel body 41 along its width direction. The partition 42 is shorter than the length of the channel body 41, so an annular channel is formed in the channel body 41, and the annular channel can specifically include an upper side ( Figure 1 The top channel, the bottom side ( Figure 1 The bottom channel of the right side ( Figure 1 The first channel 43 of the direction of the left side ( Figure 1 A second channel 44 is formed in the direction of the beam.

[0024] An air inlet damper 51 may be provided at the lower end of the channel body 41, and the air inlet damper 51 may be connected to the bottom channel when opened to allow the outside air to enter. An air outlet damper 52 may be provided at the upper end of the channel body 41, and the air outlet damper 52 may be connected to the top channel when opened to allow the inside air to be discharged.

[0025] Three layers of through holes 3 may be provided on the cabinet 1. Each layer of through holes 3 is provided above the corresponding planting rack 2. Each layer of through holes 3 may be one or more. The three layers of through holes 3 are connected to the first channel 43, so that the air in the first channel 43 and the cabinet 1 can circulate with each other.

[0026] Furthermore, in order to enhance the fluidity of air and the exchange of air between the first channel 43 and the air in the cabinet 1 , a fan 54 may be installed on the top of the partition 42 , and the fan 54 is located in the top channel.

[0027] Furthermore, a channel damper 53 is provided in the second channel 44. When the channel damper 53 is closed, and the air inlet damper 51 and the air outlet damper 52 are opened, under the traction of the fan 54, the external air enters through the air inlet damper 51, flows through the bottom channel, and enters the first channel 43. Since the fan 54 is arranged in the top channel, the fan 54 can attract the air in the first channel 43 and the cabinet 1, and all of them are discharged through the air outlet damper 52. In this way, the external circulation of the system is realized. Then, the air temperature and humidity in the cabinet 1 can be adjusted by introducing external air.

[0028] When the channel damper 53 is opened and the air inlet damper 51 and the air outlet damper 52 are closed, the air in the channel body 41 circulates among the second channel 44, the bottom channel, the first channel 43 and the top channel under the traction of the fan 54. In this process, the air in the channel body 41 can enter the cabinet 1 through the through hole 3, thereby realizing the internal circulation of the system.

[0029] Furthermore, a temperature control component may be provided in the bottom channel, and the temperature control component is used to adjust the air temperature during the internal circulation process. Specifically, the temperature control component may include an evaporator and a compressor 55 (such as Figure 2 After starting the compressor 55, the evaporator can exchange heat with the air flowing through the bottom channel, thereby reducing the air temperature. In this way, the temperature of the air in the cabinet 1 is adjusted, and the temperature and humidity of the air in the cabinet 1 can be made more uniform.

[0030] An internal cabinet temperature and humidity sensor 71 may be provided inside the cabinet 1 to detect the temperature and humidity inside the cabinet. Similarly, an external cabinet temperature and humidity sensor 72 may be provided outside the cabinet 1 to detect the temperature and humidity outside the cabinet. In this way, the temperature and humidity values ​​inside and outside the cabinet can be obtained.

[0031] See next Figure 2 , Figure 2 The structure diagram of an embodiment of a temperature and humidity control system of a fully environmentally controlled family planting machine of the utility model is shown in FIG. Figure 2 As shown, the system may also include a control terminal 6, which is electrically connected to the air inlet damper 51, the air outlet damper 52, the channel damper 53, the fan 54, the compressor 55, the cabinet temperature sensor, and the cabinet temperature sensor. The control terminal 6 can control the start and stop of the air inlet damper 51, the air outlet damper 52, the channel damper 53, the fan 54, and the compressor 55, and receive the temperature and humidity values ​​collected by the cabinet temperature sensor and the cabinet temperature sensor. In this way, under the control of the control terminal 6, the system can complete the internal circulation and the external circulation, and then adjust the temperature and humidity in the cabinet according to the set temperature and humidity values ​​and the collected temperature and humidity values. As an example, the above-mentioned controller can be a microcontroller, such as the STM32F series.

[0032] Furthermore, the system may also include a control panel 73, which is communicatively connected to the control terminal 6 and may be arranged above the cabinet 1. The control panel 73 includes control buttons for the user to set a preset temperature and humidity, and a display screen for displaying the current temperature and humidity. The control panel 73 may also include control buttons for setting plant growth parameters, etc. The plant growth parameters may be environmental conditions required for plant growth, such as light intensity, light duration, etc.

[0033] Usually, lamps are installed in the cabinet 1 to provide light to the plants on the planting rack, and nutrient solution is provided at the bottom of the planting rack 2, so that the temperature and humidity in the cabinet 1 are often higher than the set temperature and humidity values ​​after a period of time. Therefore, when the control terminal 6 detects that the temperature and humidity in the cabinet 1 are higher than the preset threshold value, it is necessary to use external circulation to reduce the temperature and humidity of the air in the channel body 41, and then perform internal circulation to make the temperature and humidity of the air in the cabinet more uniform. Furthermore, it is also possible to use internal circulation and turn on the compressor 55, and reduce the temperature of the air in the channel body 41 by absorbing heat through the evaporator, and finally adjust the humidity in the cabinet through external circulation.

[0034] During the actual working process, in response to the temperature inside the cabinet being higher than the peak value of the preset range, the temperature information outside the cabinet is collected. If the temperature outside the cabinet is lower than the peak value of the preset range, the external circulation is turned on until the temperature inside the cabinet is within the preset range and the humidity inside the cabinet is lower than the preset threshold, and then the internal circulation is turned on.

[0035] In some embodiments, the user can set a preset range of temperature and a preset threshold of humidity through the control panel 73. The control terminal 6 can receive the temperature and humidity values ​​inside the cabinet collected by the temperature and humidity sensor 71 inside the cabinet. When the above-mentioned temperature value inside the cabinet is higher than the peak value of the preset range, the control terminal 6 can receive the temperature value outside the cabinet collected by the temperature and humidity sensor outside the cabinet 72. If the temperature value outside the cabinet is lower than the peak value of the preset range, it indicates that the external air can cool the air inside the cabinet 1. At this time, open the air inlet damper 51, the air outlet damper 52 and the fan 54, close the channel damper 53, and perform external circulation, which not only realizes the exhaust operation of the air inside the cabinet 1, but also allows the external cold air to be filled into the cabinet 1. In this way, the temperature inside the cabinet can be within the above-mentioned preset range.

[0036] At the same time, due to the transpiration of plant growth, the humidity inside the cabinet is often higher than the humidity outside the cabinet after a period of operation. Therefore, while the above external circulation is adjusting the temperature, the humidity inside the cabinet is also decreasing. Therefore, the above external circulation process can adjust the temperature and humidity inside the cabinet at the same time.

[0037] When the temperature in the cabinet is within the above preset range and the humidity in the cabinet is lower than the preset threshold, the external circulation can be turned off. Finally, the internal circulation is turned on to make the temperature and humidity in the cabinet more uniform, until the temperature and humidity in the cabinet are stable and then the internal circulation is turned off.

[0038] It should be noted that the above preset range and preset threshold can be determined by those skilled in the art based on repeated experiments and the environment required for plant growth.

[0039] As an example, the preset range of the above-mentioned cabinet temperature can be 20-24°C. The preset threshold of the cabinet humidity can be 70%. When the cabinet humidity is ≧80%, the cabinet temperature is greater than 24 degrees, and the cabinet temperature outside is less than 24 degrees, first turn on the external circulation until the cabinet temperature is between 20-24°C and the cabinet humidity is less than 70%, and then turn off the external circulation. Next, turn on the internal circulation until the cabinet temperature and humidity values ​​are stable and then turn off the internal circulation.

[0040] If the temperature outside the cabinet is higher than the peak value of the preset range, turn on the internal circulation and the temperature control component so that the temperature inside the cabinet is within the preset range, then turn on the external circulation for a preset time period at a preset time interval so that the humidity inside the cabinet is lower than the preset threshold.

[0041] In some embodiments, if the value of the temperature in the cabinet collected by the temperature and humidity sensor 72 outside the cabinet by the control end 6 is higher than the peak value of the preset range, and the value of the humidity in the cabinet is higher than the preset threshold, it indicates that the external air cannot cool the air in the cabinet 1. At this time, the air in the channel body 41 can be cooled by the above-mentioned evaporator. Specifically, the channel damper 53 is opened, the air inlet damper 51 and the air outlet damper 52 are closed, and under the traction of the fan 54, the air in the channel body 41 circulates between the second channel 44, the bottom channel, the first channel 43 and the top channel. The air in the channel body 41 can enter the cabinet 1 through the through hole 3, thereby realizing the internal circulation of the system. Further, by turning on the compressor, the air heat can be absorbed by the evaporator, so that the air temperature in the cabinet is reduced and is within the above-mentioned preset range, and then the internal circulation is closed. Finally, in the scenario where the temperature in the cabinet is within the preset range and the humidity in the cabinet is higher than the preset threshold, the external circulation can be turned on at a preset time interval, and each operation is preset for a preset duration, and then the humidity in the cabinet is adjusted by the air outside the cabinet 1 until the humidity in the cabinet is lower than the preset threshold. As an example, the preset range of the above cabinet temperature can be 20-24°C. The preset threshold of the cabinet humidity can be 70%. When the cabinet temperature and the cabinet temperature outside are both greater than 24°C, it indicates that the external air cannot adjust the cabinet temperature. The internal circulation and the compressor can be turned on until the cabinet temperature drops to the above preset range, and then the internal circulation and the compressor are turned off.

[0042] Next, adjust the humidity inside the cabinet. First, turn on the external circulation and run it for a preset time of 3 minutes. After the preset time interval, run the external circulation again for 3 minutes until the humidity inside the cabinet is lower than 70%.

[0043] The above technical solution can adjust the temperature and humidity inside the cabinet in two ways according to the external temperature and humidity. This makes the adjustment process more targeted. When the temperature outside the cabinet is lower than the peak value of the preset range, the temperature and humidity are adjusted only by external air, and there is no need to start the temperature control component, thereby reducing energy consumption. When the temperature outside the cabinet is higher than the peak value of the preset range, the working efficiency of the temperature regulation is improved by starting the internal circulation and the compressor. In addition, the humidity inside the cabinet is gradually adjusted by running the external circulation for a preset time at a preset time interval. If the operating interval and operating time of the external circulation are not controlled, the temperature inside the cabinet will be affected and fluctuate. Therefore, the above technical solution of the utility model can improve the stability of the temperature inside the cabinet during the humidity adjustment process.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
