Control boxes are connected. A support stand is provided between the growth box and the control box to partition the growth box and the control box. It blows warm or cool air into the room.

Problems to be solved by the invention In the ornamental plant cultivation device described in Utility Model Application Publication No. 62-16260, when blowing warm or cold air into the growth box, the periphery of the support stand and the control box are The air volume is not uniform in the gap between the inner circumferential surface and
Therefore, variations in temperature distribution within the growth box are likely to occur.

In addition, some of the water droplets scattered during water supply and the water droplets generated by condensation flow down the outer peripheral side surface of the support base, and further wrap around and fall on the lower surface of the support base. Then, the falling water droplets will fall on equipment such as the blower inside the control box, causing equipment failure and furthermore, there is a risk of the equipment being shot.

Means for solving the problem A base casing is attached to the lower end of a transparent case that covers the support and pot holder, and the outer peripheral side of the water receiving tank provided in the base casing and the inner peripheral surface of the base casing are connected to each other. A ventilation path communicating between the inside of the case and the inside of the base casing is formed, a blower fan and a heating element are installed approximately at the lower central part of the water receiving tank, and a ventilation fan and a heating element are installed at the bottom center of the lower surface of the water receiving tank. A plurality of guide frames are provided that extend radially from the lower surface of the water receiving tank toward the peripheral edge of the lower surface, and a ring-shaped drainage guide frame that protrudes downward is provided on the peripheral edge of the lower surface of the water receiving tank.

Function Hot air blown by the blower fan and warmed by the heating element is divided approximately equally by the guide frame, flows along the guide frame, and flows into the case from the ventilation path. Therefore,
The hot air flows into the case substantially uniformly throughout the case, and the temperature distribution within the case becomes substantially uniform. Furthermore, water droplets flowing along the outer peripheral side surface of the water receiving tank are prevented from falling from the draining guide frame, wrapping around the lower surface of the water receiving tank, and falling onto the blower fan or heating element.

A water receiving tank 12 is housed in the base casing 2 and is located above the heating element 6 and has an open upper end with a certain gap between it and the heating element 6. A support frame 14 that supports a hollow cylindrical column 13 is housed in the water receiving tank 12, and the column 13 supports the water receiving tank 12.
It is located in the center of the building and is erected with its axis in the vertical direction. A wire mesh 14a is placed on the support frame 14, and a fibrous filter 15 for removing fine dust and pebbles 16 for removing large dust such as fallen leaves are laminated on the top of the wire mesh 14a. A filtration mechanism 15a configured by

A submersible pump 17, which is a water pump, is installed at the bottom of the water receiving tank 12. One end of a water pipe 18 installed inside the support column 13 is connected to the submersible pump 17, and further,
A float 19 that moves up and down according to the amount of water in the water tank 12 is provided inside the support 13, and a confirmation window 20 is formed on the side surface of the support 13 to confirm the elevation position of the float 19. There is.

The lower surface of the water receiving tank 12 is gently sloped from the center toward the periphery, and a plurality of guide frames 21 are fixed to this lower surface and extend radially from the center of the lower surface toward the periphery of the lower surface. There is.
Furthermore, a ring-shaped drainage guide frame 21a that projects downward is fixed to the peripheral edge of the lower surface of the water receiving tank 12. Moreover, the outer peripheral side surface of the water receiving tank 12 and the base casing 2
A ventilation passage 22 having a constant width is formed between the inner circumferential surface of the base casing 2 and the inside of the case to be described later. Note that the upper end edge of the water receiving tank 12 is expanded obliquely upward and is fitted into the upper inner circumferential surface of the base casing 2;
A plurality of air outlets 23 communicating with the air passage 22 are formed at equal intervals on this upper edge.

Next, a ring-shaped recess 24 is formed in the upper edge of the base casing 2, and in this recess 24, the lower ends of a pair of outer circumferential cases 25, 26 formed of a transparent member into a substantially semi-cylindrical shape are formed. is fitted in such a way that it can slide freely. Further, a top plate 27 is fixed to the upper end of the pillar 13 with screws 28, and a ring-shaped recess 29 is also formed at the peripheral edge of the top plate 27. The upper end of 26 is slidably fitted. Note that the top plate 27 is provided with a ventilation opening (not shown) that can be opened and closed. These outer peripheral cases 25, 26 and the top plate 27 constitute a transparent case 27a that covers the support 13 and a pot holder to be described later.

Next, a copy of the pot holder 30 is attached to the support 13.
are held, and a pot holder plate 31 is detachably attached to these pot holders 30.
Note that one end of a return pipe 32 is connected to the bottom surface of the pot support plate 31, and the other end of the return pipe 32 is connected to the inside of the support column 13. Also,
A distributor 33 is press-fitted into the upper part of the pillar 13, and the distributor 33 is press-fitted into the upper part of the pillar 13.
A water supply tank 34 is formed, with 3 serving as a bottom plate portion and the inner circumferential wall of the support column 13 serving as a side wall.
One end of a plurality of pipes 35 is connected to the distributor 33, and one end of a water supply pipe 36 is connected to the other end of each pipe 35. The other end of the water supply pipe 36 is routed toward the pot holder 30, and the water supply pipe 36 is provided with an adjustment knob 37 for adjusting the amount of water supplied.
Further, the support column 13 is provided with a nozzle 38 for spraying the aqueous solution in the water supply tank 34.

In such a configuration, a pot containing a plant is placed on the pot holder plate 31, or a pot 39 containing a plant is directly hooked onto the pot holder 30.
Then, the outer peripheral cases 25 and 26 are slid to cover the outer peripheral portion of the plant. Note that a certain amount of aqueous solution is placed in the water receiving tank 12.

Here, if the plants housed in the case 27a can be cultivated at room temperature, the ventilation hole provided in the top plate 27 is left open, and only the ventilation fan 4 is driven without driving the heating element 6. External air sucked into the base casing 2 by the drive of the blower fan 4 passes through the ventilation path 22, enters the inside of the case 27a from the air outlet 23, and is discharged from the ventilation port. Therefore, fresh air is constantly circulated within the case 27a, and oxygen and the like are sufficiently supplied to promote the growth of plants. Furthermore, the interior of the case 27a is airtight, preventing an abnormal temperature rise, and preventing plants from wilting due to high temperatures.

Next, in winter when the outside temperature is low,
When a temperature sensor (not shown) provided in the case 27a detects that the temperature has fallen below the set temperature, the start switch of the heating element 6 is automatically turned on, and the heating element 6 is turned on.
is driven. On the other hand, the blower fan 4 is also driven, and the air sucked into the base casing 2 by the blower fan 4 is warmed by the heating element 6 and rises as warm air, causing the air to reach the center of the lower surface of the water receiving tank 12. corresponds to The warm air that hits the lower surface of the water receiving tank 12 is divided into approximately equal amounts by the guide frame 21 and guided toward the periphery of the lower surface of the water receiving tank 12, and further passes through the ventilation passage 22 and the air outlet 23. Then, air is blown to the case 27a.
Therefore, hot air is blown out substantially uniformly from each air outlet 23, and the temperature distribution within the case 27a becomes substantially uniform. Further, since the warm air flows along the inner circumferential surfaces of the outer circumferential cases 25 and 26, the inner circumferential surfaces of the outer circumferential cases 25 and 26 are prevented from fogging.
Moreover, since the water receiving tank 12 contains an aqueous solution, the temperature inside the case 27a is kept constant even if the heating element 6 is driven intermittently for a long time. moreover,
By fixing a plurality of guide frames 21 to the lower surface of the water receiving tank 12, the strength of the water receiving tank 12 is increased and deformation is prevented.

Next, if for some reason the aqueous solution overflows from the water receiving tank 12 flows down along the outer peripheral side of the water receiving tank 12, these aqueous solutions fall from the draining guide frame 21a to the bottom of the base casing 2. However, it is prevented from going around to the bottom surface of the water receiving tank 12 and falling onto the heating element 6 and the ventilation fan 4. Note that the aqueous solution that has fallen to the bottom of the base casing 2 is discharged to the outside from a drain hole (not shown).

Next, the supply of an aqueous solution to plants will be explained. When the submersible pump 17 is driven, the water receiving tank 1
The aqueous solution in 2 is pumped up through the water pipe 18 and stored in the water supply tank 34. And the adjustment knob 37 attached to the water supply pipe 36
When opened, the aqueous solution flows down from the water supply pipe 36 under its own weight, and water is supplied to the plants planted in each pot. Further, the amount of water supplied is adjusted by adjusting the opening degree of the adjustment pot 37, and by selectively opening and closing the adjustment pot 37, water is supplied only to plants that require water supply. Further, by filling the water supply tank 34 with the aqueous solution, the aqueous solution is sprayed from the nozzle 38. In addition, water supply pipe 3
The water pressure of the aqueous solution supplied from 6 is low, and the adjustment pot 37 may have an extremely simple structure.

Excess aqueous solution of the aqueous solution supplied to the plants from the water supply pipe 36, or the aqueous solution supplied by a water heater or the like when the outer peripheral cases 25 and 26 are opened, falls onto the filtration mechanism 15a, passes through the filtration mechanism 15a, and enters the water receiver. It is refluxed into the tank 12. Here, large garbage such as plant leaves is filtered by pebbles 16,
Fine dust contained in the aqueous solution is filtered out by the fibrous filter 15. Therefore, the water receiving tank 12
An aqueous solution containing almost no dust is refluxed inside. Therefore, the inside of the water receiving tank 12 is not contaminated with dirt, and the aqueous solution is not contaminated with dirt, and the frequency of cleaning the water receiving tank 12 and replacing the aqueous solution is significantly reduced. .
Furthermore, since the filtration mechanism 15a is provided across the entire opening of the water receiving tank 12, the effective filtration area can be made sufficiently large, making it difficult for clogging to occur and providing sufficient water over a long period of time. Can maintain filtration action. Furthermore, since the filtration mechanism 15a is installed in an easily accessible location, large debris on the pebbles 16 can be easily removed, and filtration performance can be maintained.

Next, since the blower fan 4, heating element 6, control device 10, etc. are all housed in the base casing 2 located at the lower part of the case 27a, the exterior is clean and aesthetically improved. Furthermore, electrical components such as the heating element 6 are isolated so as not to be exposed to aqueous solution, and there is no risk of shoots or the like caused by exposure to aqueous solution, thereby increasing safety. Also,
When the case 27a is removed in summer or the like when the case 27a is not needed, no frame members remain around the plant, so the aesthetic appearance is not impaired.

Effects of the invention As described above, the present invention installs a blower fan and a heating element in the lower central part of the water receiving tank, and places the inside of the base casing between the outer circumferential side of the water receiving tank and the inner circumferential surface of the base casing. By forming a ventilation path that communicates with the inside of the case where plants are cultivated, and by providing multiple guide frames on the bottom surface of the water tank that spread radially from the center of the bottom surface to the periphery of the bottom surface.
The warm air heated by the heating element can be divided almost equally by the guide frame and blown into the case. Therefore, the warm air can be blown into the case almost evenly over the entire case to reduce the temperature inside the case. The distribution can be made almost uniform, so that the plants being cultivated can grow almost uniformly.In addition, a ring-shaped draining guide frame that protrudes downward is provided on the periphery of the lower surface of the water receiving tank. This allows the aqueous solution that flows down along the side surface of the outer circumference of the water receiving tank to fall from the draining guide frame, and therefore prevents the aqueous solution that flows down along the outer circumferential surface of the water receiving tank from going around the bottom surface of the water receiving tank. Also, it can prevent the water from falling onto the blower fan or heating element after going around the bottom surface of the water receiving tank, and has the effect of preventing malfunctions, shoots, etc. due to adhesion of aqueous solution.
