Description

  The present invention relates to a plant appreciation and growth apparatus.

  There is a device that covers a transparent case on a box with a temperature and humidity control device and grows the plants inside the case, but the temperature and humidity are adjusted by circulating air only between the case and the box.

JP 59-169425 A

  However, with such air circulation alone, carbon dioxide becomes deficient due to plant respiration, and it will not last for a long time. In addition, although a compression heat pump is provided as a temperature control device, the noise of the compressor becomes a problem when used in a quiet place.

  In order to solve the above-mentioned problems, the present invention comprises a box body on which a plant is placed and a lid body that is detachably attached to the box body, and a compressed air heat source heat pump for temperature and humidity control inside the lid body And a fan and a humidifier are provided inside the box, and the compressor of the heat pump is arranged at the center of the box to surround the periphery, and the box forms a ventilation inlet leading to the inside of the lid In addition, the most main feature is that a ventilation outlet hole that also serves as a grip hole is formed in the lid so as to allow ventilation.

According to the invention of claim 1, since the inside of the lid can be ventilated, there is no fear of carbon dioxide shortage, plant growth promotion and life extension can be achieved, and the viewing period can be maintained for a long time. A compressor is placed in the center of the box, and the surroundings and the outer periphery of the box are double soundproofed, so no noise leaks out and you can use it in a quiet place without worrying about it. The ventilation outlet hole can be used as both a ventilation hole and ventilation, and anti-fogging effect can be expected, and there is no need to use special anti-fogging processing and materials that are expensive.
According to the second aspect of the present invention, when a plant that needs to be shielded from light or a plant that needs to be lit is cultivated and appreciated, the plant can be shielded from light or lit by simply rotating the lid.
In the invention of claim 3, the partition material can change the volume ratio in accordance with the amount of parts on the evaporator side and the condenser side to utilize the space without waste, and the box and thus the entire apparatus can be made compact.

  1 to 3 show an embodiment of the plant appreciation and growth apparatus according to the present invention, and solid and dotted white arrows indicate the blowing direction. This plant appreciation and breeding apparatus includes a box 1 in which the plant S is placed, and a lid 2 that is detachably attached to the box 1 so as to cover the plant S. A compression air heat source heat pump C, a fan 3 and a humidifier 4 for controlling the temperature and humidity inside the lid 2 are provided inside the box 1, and the compressor 5 of the heat pump C is arranged at the center of the box 1. Then, a ventilation inlet 14 communicating with the inside of the lid body 2 is formed in the box body 1 and an appropriate number of ventilation outlet holes 7 serving as gripping holes are formed in the lid body 2 so as to allow ventilation.

  The heat pump C includes a condenser 9 for exchanging heat of the circulating refrigerant with heat exchange air such as return air and outside air, an evaporator 8 for exchanging heat of the air supplied inside the lid with the circulating refrigerant, and a compressor 5. And an expansion valve, a forward / reverse switching valve (four-way valve) in the refrigerant circulation direction, a liquid receiver (not shown), etc., which are connected by piping to constitute a refrigerant circulation circuit and condensed by the switching valve The heat absorption and heat dissipation (evaporation function and condensation function) of the container 9 and the evaporator 8 are configured to be switchable. The air supply air inside the lid is cooled or heated by the evaporator 8 of the heat pump C, and the temperature is controlled by cold air or hot air. In the illustrated example, two evaporators 8 are provided on the windward side and the leeward side, and when the windward side functions as an evaporator, the leeward side functions as a reheater, for example, the refrigerant (hot gas) flowing through the condenser 9 A part is bypassed to the evaporator 8 on the leeward side so that it can be supercooled, dehumidified and reheated, but this leeward side is omitted and the heat pump C can be configured with the evaporator 8 as one. is there.

  The box 1 is formed in a hollow cylindrical shape, and a partition member 6 that partitions the inside of the box 1 into an evaporator side A and a condenser side B of the heat pump C is provided so that the volume ratio of the inside can be changed. An evaporator 8, a fan 3, a humidifier 4, and a humidifier water supply tank 11 are arranged on the evaporator side A of the box 1, and a condenser 9, a fan 3 and a controller 12 are arranged on the condenser side B. To do. A ventilation inlet 14, a blower outlet 15, and a suction port 16 are formed on the evaporator side A of the box 1, and the lid body internal space formed by covering the box 1 with the lid 2, the blower outlet 15, and the suction The suction port 16 and the ventilation inlet 14 are disposed on the windward side of the evaporator 8, and the air outlet 15 is disposed on the leeward side of the evaporator 8. An air inlet 20 and an air outlet 17 are formed on the condenser side B of the box body 1, the air inlet 20 is disposed on the wind of the condenser 9, and the air outlet 17 is disposed on the lee of the condenser 9.

  The controller 12 controls the capacity of each of the heat pump C, the fan 3 and the humidifier 4 and switches between refrigerant evaporation and refrigerant condensation of the evaporator 8. The box 1 is provided with an illumination 13, various gauges 18 indicating temperature and humidity, a grid-like table 19 on which the plant S is placed, and a drain pan (not shown). For example, the controller 12 sets the temperature / humidity according to the optimum growth environment conditions of the plant S, and the evaporator 8, the fan 3, and the humidifier 4 circulate the lid body air to control the temperature / humidity, and ventilate. Ventilation is performed simultaneously by taking fresh air from the inlet 14, mixing it with the air inside the lid, and discharging a predetermined amount from the ventilation outlet hole 7. Irrigation can be performed by holding the ventilation outlet hole 7 and removing the lid 2 or by inserting a jug from the ventilation outlet hole 7. Although not shown in the figure, a remote controller or the like may be provided for operation. Moreover, the arrangement | positioning change of the various components to the evaporator side A and the condenser side B is free.

  FIG. 4 shows a transparent lid 2 that shields light from a predetermined range (a light shielding range is indicated by a grid-like line), and this lid 2 is covered with a box 1 so as to be pivotable and detachable. For example, as shown in FIGS. 4A, 4 </ b> B, and 4 </ b> C, the lid 2 can be rotated so that the plant S can be easily shielded from light and can be lit. The light shielding range and part of the lid 2 are not limited to the illustrated example, and can be changed variously. FIG. 5 shows an example in which the upper portion of the box 1 is made into an outer casing shape, and the lid 2 is sized in accordance with the outer peripheral edge thereof. Thus, it is free to change the size and height of the lid body 2 and the box body 1 or to change the shape and structure to various shapes such as a quadrangular prism shape.
