Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a cover opening/closing device for a plant ornamental cultivator.

Conventional Technology In recent years, with the growing popularity of gardening, ornamental plant cultivators for home use have become popular.These ornamental plant cultivators include tanks for storing water and pumps for pumping up the 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 that the invention aims to solve In the case of a structure in which the opening/closing cover is engaged with a guide groove and slid directly, as the opening/closing cover becomes larger, a large tensile force is required to open and close it.
It becomes difficult to open and close the opening/closing cover smoothly.

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 Problem A tank for storing water and a pump for pumping water in the tank are housed in a base casing, and a main case for housing plants to be ornamentally cultivated is placed on the base casing for ornamental plants. In the cultivator,
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 a plate made of a resin material is inserted into a side surface of the guide groove. At the same time, a round rod was inserted into the bottom of the guide groove.

Function: A plate made of a resin material is inserted into the side surface of the guide groove, which reduces friction between the side surface of the cover and the plate on the side surface of the guide groove when opening and closing the cover. Furthermore, a round bar is inserted into the bottom of the guide groove, and the bottom of the opening/closing cover and the round bar are in line contact.
Friction between the bottom part of the opening/closing cover and the round bar when opening/closing the opening/closing cover is reduced.

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 water supply tank 4 is provided at the top of the support column 12.
A nozzle 47 is provided to spray the water in the container.

In such a configuration, a plant can be placed inside the main body case 26 by placing a pot in which a plant is planted on the pot holder plate 40 or by directly hooking a pot 48 in which a plant is planted to 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 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 port. 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. Opening/closing operations of the opening/closing covers 27 and 28 are performed using the opening/closing cover 2.
This is done by sliding the opening/closing cover 2 along the guide grooves 30, 31.
Since the lower end portions 7 and 28 are in line contact with the upper end portion of the round bar 33, the frictional force at the contact portion between the opening/closing covers 27 and 28 and the round bar 33 is reduced. Further, a plate 32 formed of a resin material is press-fixed to the outer circumferential side surface of the guide grooves 30, 31, and a plate 32 is press-fixed to the portion of the opening/closing covers 27, 28 that faces the inner circumferential side surface of the guide grooves 30, 31. Since a plate 34 made of a resin material is bonded to the plate 34, when the opening/closing covers 27, 28 are opened/closed, the opening/closing covers 27, 28 come into contact with the plate 32, or the plate 34 comes into contact with the side surfaces of the guide grooves 30, 31. Therefore, the resistance due to these contacts is reduced. Therefore, the closing covers 27 and 28 can be opened and closed smoothly with little force.

In addition, in this embodiment, the plate 32 is pressed and fixed by the round bar 33, and the plate 34 is
Although the opening/closing covers 27 and 28 were glued, the plate 32 was glued to the outer peripheral side of the guide grooves 30 and 31, and the plate 34 was glued to the guide grooves 30 and 31.
It may also be glued to the inner side surface.

In addition, the guide grooves 30 and 3 in the base casing 2 are provided in the guide grooves 36 and 37 in the top plate 29.
By providing a round bar or plate as in 1,
Opening/closing operations of the opening/closing covers 27, 28 can be performed even more smoothly.

Effects of the invention As described above, this invention inserts a round rod into the bottom of the guide groove in which the lower end of the opening/closing cover is engaged, thereby making the contact between the bottom of the opening/closing cover and the round rod a line contact state. It is possible to reduce the frictional force when opening/closing the opening/closing cover, and by inserting a plate made of resin material into the side of the guide groove, the opening/closing cover does not come into contact with the plate when opening/closing the opening/closing cover. As a result, the resistance caused by contact can be reduced, and the opening/closing cover can be opened and closed smoothly with little force. Furthermore, there is no need to create a new mold when molding plates or round bars. Since there are no overlapping parts of the opening/closing cover and other parts of the main body case, by using a thin plate, it is possible to reduce costs by using existing parts. This has effects such as being able to sufficiently maintain the sealing effect of the overlapping portions.
