Description

[Detailed description of the invention] Industrial application field The present invention relates to an ornamental cultivation device for plants.

Conventional Technology In recent years, with the increasing popularity of gardening, ornamental cultivation devices for home use have become popular.These ornamental cultivation devices include tanks that store water and pumps that pump up water in the tank. It is generally constructed of a base casing that houses a heater, etc., and a main body case that houses ornamental plants and is placed on the base casing.

Further, the main body case is provided with an opening/closing cover for taking plants in and out, etc., and a sliding type is widely used as such opening/closing cover. Structures for sliding the opening/closing cover include a structure in which the lower end of the opening/closing cover is engaged with a guide groove formed of resin or the like and sliding directly, or a door roller is attached to the lower end of the opening/closing cover and this door roller is engaged with the guide groove. There are structures that allow you to slide them together.

Problems to be solved by the invention In the case of a structure in which the opening and closing cover is engaged with the guide groove and slid directly, as the opening and closing cover becomes larger, a large pulling force is required to open and close it.
This makes it difficult to smoothly open and close the opening/closing cover.

In the case of a structure in which the door roller attached to the lower end of the opening/closing cover is engaged with a guide groove and slid, the door roller is generally mounted movably to ensure smooth sliding, and the mounting structure is complicated. It's getting old.
Furthermore, since a door roller mounting member is used to attach the door roller, if there are two opening/closing covers, there will be large gaps where the opening/closing covers overlap, and where the opening/closing covers overlap with other parts of the main case. , new sealing members are required to improve heat retention and airtightness inside the main body case.

Means for Solving the Problems A tank for storing water and a pump for pumping up water in this tank are housed in a base casing, and a main body case for housing ornamental plants is placed on the base casing. In the ornamental cultivation apparatus, a slidable opening/closing cover is provided on the main body case, a guide groove with which a lower end of the opening/closing cover engages is formed at the upper end of the base casing, and substantially equal intervals are formed on the bottom surface of the guide groove. A plurality of recesses are formed, and a steel ball is provided in these recesses so as to be freely rollable, a plate that abuts the upper end of the steel ball is provided in the guide groove, and the opening/closing cover is mounted on the plate. I placed it.

Function The friction between the opening/closing cover and the plate is sliding friction, and the friction between the plate and the steel ball is rolling friction, and rolling friction is much smaller than sliding friction. Therefore, when force is applied in the sliding direction to open and close the cover, the cover slides integrally with the plate, and the cover is opened and closed.

are held, and a pot holder plate 40 is detachably attached to these pot holders 39.
Note that one end of a return pipe 41 is connected to the bottom surface of the pot support plate 40, and the other end of the return pipe 41 is connected to the inside of the support column 12. Also,
A distributor 42 is press-fitted into the upper part of the pillar 12, and the distributor 42 is press-fitted into the upper part of the pillar 12.
A water supply tank 43 is formed, with 2 serving as a bottom plate and the inner circumferential wall of the support column 12 serving as a side wall.
One end of a plurality of pipes 44 is connected to the distributor 42, and one end of a water supply pipe 45 is connected to the other end of each pipe 44. The other end of the water supply pipe 45 is routed toward the pot holder 39, and the water supply pipe 45 is provided with an adjustment knob 46 for adjusting the amount of water supplied.
Further, the support column 12 is provided with a nozzle 47 for spraying water in the water supply tank 43.

In such a configuration, the plant can be placed inside the main body case 26 by placing the pot with the plant on the pot holder plate 40 or by directly hooking the pot 48 with the plant on the pot holder 39. Perform storage.

Here, if the plants stored in the main body case 26 can be cultivated at room temperature, the ventilation opening (not shown) provided in the top plate 29 is also opened, and the ventilation fan is turned on without driving the heating element 5. Only 4 is driven. External air sucked into the base casing 2 by the drive of the blower fan 4 passes through the ventilation path 22, is blown out into the main body case 26 from the air outlet 23, and is discharged from the ventilation opening. Therefore, fresh air is constantly circulated within the main body case 26, and oxygen and the like are sufficiently supplied to promote the growth of plants.
Furthermore, the inside of the main body case 26 is made airtight, preventing an abnormal temperature rise, thereby preventing plants from wilting due to high temperatures.

Next, in winter when the outside temperature is low,
When a temperature sensor (not shown) provided inside the main body case 26 detects that the temperature has fallen below the set temperature, the start switch of the heating element 5 is automatically turned on, and the heating element 5 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 heated as it passes around the heating element 5 and becomes hot air, which leads to the ventilation passage 22 and the wind outlet. 23 and into the main body case 26.
The temperature inside the main body case 26 rises due to this warm air, and the inside of the main body case 26 is maintained at a temperature suitable for cultivating plants. The hot air heated by the heating element 5 flows along the guide frame 21, so that the hot air is blown out almost uniformly from all the air outlets 23, and the temperature distribution inside the main body case 26 is almost uniform. Become. In addition, since the warm air flows along the inner peripheral surfaces of the openable covers 27 and 28, the openable covers 27 and 2
The inner peripheral surface of No. 8 is prevented from fogging. Moreover, since water is contained in the tank 11, the humidity inside the main body case 26 is kept constant even if the heating element 5 is driven intermittently for a long time.

Next, the supply of water to plants will be explained.
When the submersible pump 17 is driven, water in the tank 11 is pumped up through the water pipe 18 and stored in the water supply tank 43. Then, by opening the adjustment pot 46 attached to the water supply pipe 45, water flows down from the water supply pipe 45 by 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 46, and by selectively opening and closing the adjustment pot 46, water is supplied only to plants that require water supply. Further, by filling the water supply tank 43 with water, water is sprayed from the nozzle 47. Note that the water pressure of the water supplied from the water supply pipe 45 is low, and the adjustment pot 46 may have an extremely simple structure.

Excess water from the water supplied to the plants from the water supply pipe 45 or the water supplied by a water heater or the like by opening the opening/closing covers 27 and 28 falls onto the filtration mechanism, passes through the filtration mechanism, and enters the tank 11. It is refluxed. Here, large debris such as plant leaves should be placed with 16 pebbles.
The fine dust contained in the water is filtered by the fibrous filter 15. Therefore, water containing almost no dirt is returned to the tank 11. Therefore, the inside of the tank 11 is not contaminated with dirt and the water is not contaminated with dirt, and the frequency of cleaning the tank 11 and replacing the water is significantly reduced. Moreover, since the filtration mechanism is provided over the entire opening of the tank 11, the effective filtration area can be made sufficiently large, making it difficult for clogging to occur and providing sufficient filtration action over a long period of time. Can be maintained. Furthermore, since the filtration mechanism is installed at a location that is easily accessible, large debris on the pebbles 16 can be easily removed, and filtration performance can be maintained.

Next, the opening/closing operations of the opening/closing covers 27, 28, which are performed when taking out/taking out plants, etc., will be explained. When force is applied to the opening/closing covers 27, 28 in the sliding direction, the sliding friction between the opening/closing covers 27, 28 and the plate 34 causes the plate 34 to
The rolling friction between the steel ball 33 and the steel ball 33 becomes extremely small. Therefore, the steel ball 33 rolls in the recess 32, the opening/closing covers 27, 28 slide in the guide grooves 30, 31 together with the plate 34, and the opening/closing covers 27, 28 can be opened and closed smoothly with a small force. It will be done.

Effects of the invention As described above, the invention provides a steel ball that can be freely rolled in the recesses formed at approximately constant intervals on the bottom of the guide groove, and a plate that is placed in the guide groove and abuts the upper end of the steel ball. By placing the opening/closing cover on the plate, the rolling friction between the plate and the steel balls is much smaller than the sliding friction between the opening/closing cover and the plate, making it easier to open/close the opening/closing cover. In some cases, the opening/closing cover slides integrally with the plate, allowing the opening/closing operation of the opening/closing cover to be performed smoothly with a small amount of force.Furthermore, since there is a plate between the opening/closing cover and the steel ball, the opening/closing cover slides over the steel ball. The shock when climbing over the steel balls is reduced, making it possible to open and close the opening/closing cover even more smoothly. It also prevents the opening/closing cover from being damaged or worn out when it goes over the steel balls. The structure can be made simpler than when used, and the spacing between the overlapping parts of the opening/closing covers and the overlapping parts of the opening/closing cover and other parts of the main body case can be made small enough to avoid contact. Therefore, there is an effect that it is not necessary to provide a sealing member in these overlapping parts, resulting in an even simpler structure.
