Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a plant ornamental cultivation device.

BACKGROUND OF THE INVENTION In recent years, with the increasing popularity of gardening, devices for cultivating plants for home use have become popular. Here, the structure of conventional ornamental cultivation equipment is to have a case with a transparent plate such as a glass plate or acrylic plate attached to a box-shaped frame made of aluminum sash, etc., and a ventilation system that can be opened and closed to provide natural ventilation. It is common to have an opening and a panel heater installed inside the case to adjust the temperature in winter.

Problems that the invention aims to solve: First, when the ventilation openings are closed, the inside of the case is not ventilated, which is not good for the growth of plants. Also,
Plant ornamental cultivation equipment is often placed indoors with little air flow, and it is difficult to provide sufficient ventilation even if the ventilation openings are opened.

Next, even if you try to raise the temperature inside the case by using a panel heater, etc., because there is little air flow inside the case, only the area around the panel heater etc. will rise in temperature, making it impossible to raise the temperature inside the case evenly. Have difficulty. Therefore, in winter, leaves and stems that extend close to the inner peripheral surface of the case may wilt due to the low temperature.

Further, the humidity inside the case is generally high due to watering plants or the like. For this reason, the inner peripheral surface of the case may become cloudy due to the water vapor, making it difficult to clearly see the plants inside the case. Furthermore, since the inside of the case is highly humid, electrical components such as panel heaters must have a completely waterproof function to prevent accidents such as shooting, which increases the cost of the components.

On the other hand, when using a panel heater, etc. continuously, the humidity inside the case may drop significantly due to the rise in temperature and evaporation of moisture.
The drawback is that it has a negative effect on plant growth.

Means for Solving the Problem An outer casing made of a transparent member that covers the outer periphery of a support and a plurality of pot holders attached to the support, a ventilation opening that can be freely opened and closed, and an upper end of the outer casing are provided. A covering top plate is provided, and a base casing is attached to the lower end of the outer peripheral case. A ventilation fan that takes in air from the outside, a heating element located close to above the ventilation fan, and a water receiving tank located above the heating element are provided in the base casing, and the outer peripheral surface of the water receiving tank and the water receiving tank are provided in the base casing. A ventilation passage communicating with the inside of the outer peripheral case is provided between the inner peripheral surface of the base casing and the inner peripheral surface of the base casing.

Function: If plants can be cultivated at room temperature, the ventilation openings on the top plate should be placed on a flat tree, and the ventilation fan should be driven. External fresh air sucked into the base casing by the blower fan flows into the outer case from the ventilation passage, circulates inside the outer case, and then is discharged from the ventilation opening. Therefore, fresh air will always circulate inside the outer peripheral case.

When the temperature is low, such as during winter, the blower fan is driven and the heating element is also driven. The air sucked into the base casing by the blower fan is heated by the heating element, becomes hot air, flows into the outer case from the ventilation path, and increases the temperature inside the outer case. The warm air is blown out along the inner circumferential surface of the outer case and is blown by the blower fan to circulate within the outer case, so that the temperature distribution inside the outer case becomes substantially uniform.

The support column 13 is located at the center of the water tank 12 and extends upward. A filter 15 for removing fine dust and pebbles 16 for removing large dust such as fallen leaves are stacked on the top of the wire mesh 14a placed on the support frame 14, and the bottom of the water tank 12 A submersible pump 17 is installed. Said submersible pump 1
7 is connected to one end of a water pipe 18 that is piped inside the support 13, and furthermore, a float 19 is provided inside the support 13 and moves up and down according to the amount of water in the water receiving tank 12. A confirmation window 20 for confirming the ascending and descending position of the float 19 is formed on the side surface of the support column 13. Furthermore, a plurality of guide frames 21 are radially fixed to the lower surface of the water receiving tank 12 and serve as a blowing guide for the air warmed by the heating element 6 and serve as reinforcing members for the water receiving tank 12.

A ventilation passage 22 is formed with a constant width between the outer peripheral surface of the water receiving tank 12 and the inner peripheral surface of the base casing 2. Further, the upper end edge of the water receiving tank 12 expands obliquely upward and is fitted into the upper inner circumferential surface of the base casing 2, and the upper end edge has a plurality of holes communicating with the ventilation passage 22. Wind outlets 23 are formed at equal intervals.

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, and the outer case 25, 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.

Next, a plurality of pot holders 3 are attached to the support 13.
0 are attached, and a pot holder plate 31 is detachably attached to these pot holders 30. In addition, one end of the return pipe 32 is connected to the bottom of the pot support plate 31, and the return pipe 32
The other end is connected to the inside of the support column 13.
Further, a distributor 33 is press-fitted into the upper part of the pillar 13.

Go inside. This warm air causes the outer case 25,
The temperature inside 26 is increased and maintained at a temperature suitable for growing plants. In addition, since the hot air heated by the heating element 6 flows along the guide frame 21, the hot air is blown out almost uniformly from all the air outlets 23, and the temperature distribution inside the outer peripheral cases 25 and 26 is approximately equal. It becomes uniform. In addition, the hot air is
In order to flow along the inner peripheral surface of 6, the outer periphery case 2
The inner circumferential surfaces of Nos. 5 and 26 are anti-fogged. Moreover, since water is contained in the water receiving tank 12, the humidity in the outer circumferential cases 25, 26 can be kept constant even if the heating element 6 is driven intermittently for a long time.

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 outer circumferential cases 25, 26, the external appearance is streamlined and the aesthetic appearance is improved. Furthermore, the electrical components such as the heating element 6 are isolated from water so that there is no danger of shoots or the like caused by water splashing, thereby increasing safety. Also,
When the top plate 27 and the outer cases 25, 26 are removed in summer or the like when the outer cases 25, 26 are not needed, the aesthetic appearance is not impaired because no frame members remain around the plants.

Effects of the invention The present invention provides a blower fan inside the base casing as described above, and the air sucked in from the outside by the blower fan is connected between the outer circumferential surface of the water receiving tank provided inside the base casing and the inner circumferential surface of the base casing. By blowing air into the outer case through the ventilation passage provided in between, and exhausting it through the ventilation opening provided on the top plate, fresh air is constantly circulated inside the outer case to encourage plant growth. In addition, by installing a heating element close to the top of the blower fan, at low temperatures, the air sucked in by the blower fan is heated by the heating element to become warm air, and this warm air is blown into the outer case. It is possible to increase the temperature inside the outer case and encourage the growth of plants.Moreover, the warm air is blown by a fan and the warm air is blown into the outer case from a part along the inner circumferential surface of the outer case. As a result, the temperature distribution inside the outer case can be made almost uniform, and by keeping water in the water receiving case, the humidity inside the outer case can be maintained at an almost constant level. has.
