Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a plant growing device that promotes the germination, growth, etc. of plants.

[Prior Art] Conventionally, as a plant growing device, for example, a garden case is known. This garden case is equipped with a heating unit inside, and by heating the entire interior with this heating unit, it warms the multiple flowerpots housed inside and promotes the germination and growth of seeds (including bulbs, etc.) The structure is as follows. In this case, the heating unit uses a nichrome wire or the like as a heating element, and the nichrome wire is protected by being covered with a protective member so that it is not exposed.

[The problem that the invention aims to solve + JIU] However, in the garden case mentioned above, the entire interior is heated by a heat generating unit, so it is difficult to heat the loam of the flower pot to the inside. In order to promote the germination and growth of seeds, it is necessary to heat them to a high temperature using one heating unit, which poses problems such as poor heating efficiency and high power consumption. In addition, since the 1st heating unit uses nichrome wire as the heating element, it is necessary to protect the nichrome wire with a protective member, etc. so that it does not become exposed, making the structure of the 1st heating part complicated and expensive. There is also the problem.

[1] The first object of this invention is to provide a plant growing device that can efficiently promote seed germination and flowering with low power consumption, and that can be easily manufactured in 4R construction with 51 heat sections and at low cost. It is about providing.

[Means for Solving the Problems] The plant growing device of the present invention has a case body made of a thermally conductive material that accommodates loam, and a case body that is made of a heat-generating resistor and covered with an insulating member. A heat-generating member is wrapped around the case body, and the loam inside the case body is heated by this planar heat-generating member.

[Function 1] According to the plant growing device of the present invention, the planar heating element warms the soil inside the case body, so there is no need to heat the inside of the case body to a high temperature as in the conventional case. Therefore, power consumption is low, the loam can be efficiently heated, and the germination and growth of seeds embedded in the loam can be favorably promoted. In this case, since the case body is made of a thermally conductive material, even if the planar heating element is wrapped around the outer wall of the case body, the loam inside the case body can be satisfactorily warmed. In addition, since the planar heating element has a structure in which the heating resistor is covered with an insulating material, it is only necessary to wrap it around the outer surface of the case body, making it easy to attach to the case body. The structure is not complicated, is simple, and can be manufactured at low cost.

[Example] Hereinafter, an example of this output 1J will be described with reference to FIGS. 1 to 4.

FIG. 1 is a perspective view of the plant growing device. This plant￥fL
&The device consists of a case body l1 a planar heat generating member 2 a protective case 3
, thermistor 4. It consists of a socket 5, a power cord 6, etc., and the power cord 6 is inserted into the socket 5 and connected to the planar heat generating member 2, which causes the planar heat generating member 2 to generate heat to warm the loam inside the case body l, and also to heat the loam inside the case body l. The temperature inside the main body 1 is detected by a thermistor 4 and controlled to be kept constant. Each member will be explained in order below.

The case body l is for storing loam soil for growing seeds, etc., and as shown in Fig.
"The second part side has a large diameter and the bottom side has a small diameter." The case body 1 is made of a thermally conductive synthetic resin, such as ABS resin, polystyrene resin, acrylic resin, etc. A mounting groove 7 is spirally formed in the outer wall of the case body l from the lower end to the upper end. This installation
gI7 accommodates and adds a planar heat generating member 2, which will be described later, and its width is the same as or slightly wider than the planar heat generating member 2, and the depth is equal to the thickness of the planar heat generating member 2. It is formed almost the same way. Further, a pair of screw holes 8 and a lead insertion hole 9 are formed in the case body 1 near the to end of the mounting groove 7 so as to penetrate from the inside of the case body 1 to the outside. Furthermore, on the entire periphery of the upper part of the case body l,
An edge 10 is formed. As shown in FIG. 3, this edge 10 extends outward from the upper edge of the case body l in a watertight manner, and its tip side is provided with a predetermined gap between it and the side wall of the case body l, that is, a protective case to be described later. The upper part of 3 extends vertically downward with a gap that allows insertion. Note that holes 11 for cutting wood are formed in the bottom of the main body case 1.

The planar heat generating member 2 heats the loam inside the case body, and as shown in Fig. 2, the whole is long. The mounting fIg is formed into an iF shape and is formed on the outer wall of the case body l!
7, from the lower end side to the upper end side, and is bonded with an adhesive or the like and wound spirally around the outer wall of the case body l. This planar heat-generating member 2 is made of a 4I in which one heat-generating resistor 12 is covered with an insulating member 13 as shown in Figure t53.
The heating resistor 12, which is a blank, is made up of two conductive wires 14.
, 14, a heat generating resistance member 15 is provided between them. The two conductive wires 14.14 are made of metal such as copper or aluminum, and each end is semi-clipped to an electrode pin 16.16 (to be described later). In the case of thin heat-generating wires made of foil or the like, a structure may be adopted in which multiple racks are passed at equal intervals between the two conductive wires 14 and wires 4, or they are knitted in a net shape. Insulating member 13
is intended to protect and insulate the heating resistor 12,
Completely cover the heating resistor 1 so that the heating resistor 12 is not exposed.
Cover 2. In this case, since the insulating member 13 is required to have heat resistance, a thermosetting resin such as polyimide resin or polyamide resin is preferably used, with a maximum allowable temperature of 130 to 230°C, but is not limited thereto.

The protective case 3 is attached to the outside of the case body l to protect the planar heat generating member 2, and is preferably made of a material with heat insulation properties, and has the same shape as the case body l, as shown in FIG. It is formed into a slightly larger tapered cylindrical shape. A notch 17 is formed in the upper part of the protective case 3, and a cutout part 17 is formed in which a socket 5, which will be described later, is arranged, and wood cutting holes 18 are provided in the bottom part. Further, when the case body 1 is inserted into the protective case 3 from the L side, the upper peripheral edge of the protective case 3 is inserted into the gap between the edge lO of the case body 1 and the outer wall, as shown in FIG.

The thermistor 4 is for detecting the temperature of the material inside the case body l, and as shown in FIG.
It is pulled out to the outside through the lead insertion hole 9.9.

The socket 5 is into which the plug 20 of the power cord 6 is removably inserted, and as shown in FIG. It is attached to the case body 1 with a mounting fitting 22. That is, the socket main body 21 is made of synthetic resin or the like, and, as shown in FIG. 2, is formed in an inverted "convex" shape, and has a pin insertion hole 23 and a lead insertion hole 24 penetrating from side to side. A screw hole 25 is formed on the upper surface side. The mounting bracket 22 is used to attach the socket body 21 to the case body l, and is made by bending a flat plate into an "L" shape.
A screw insertion hole 26 is provided in the vertical part (F) corresponding to the screw hole 8 of the case body l, and a screw insertion hole 27 is provided in the water + part.
is formed corresponding to the screw hole 25 of the socket body 21.

By the way, when attaching such a socket 5 to the case body l, first screw the socket body 21 to the wooden part of the mounting bracket 22, and then insert the bottle insertion hole 2.
3, the electrode pins 16 of the planar heat generating member 2 are inserted from the back side and protruded to the front side. Then, twist the planar heat generating member 2 90 degrees near the socket 5, and in this state apply it to the screw hole 8 and lead insertion hole 9 of the case body l.In this case, the planar heat generating member 2 is twisted 90 degrees. 6 of the case body l by the planar heat generating member 2.
The holes 8 and 9 will not be blocked, so the electrode lead 19 of the thermistor 4 that protrudes outside through the lead insertion hole 9 of the case body 1 is inserted into the lead insertion hole 24 from the back side of the socket body 21. Let it protrude to the front side, and in this state screw the mounting bracket 22 into the case body l. As a result, the socket 5 is attached to the case body 1 with the electrode pins 16 and electrode leads 19 protruding toward the front side of the socket body 21, as shown in FIG.

The power cord 6 is used to connect the socket 5 to a power source such as an outlet (not shown), and as shown in FIG. The other end (left end) is provided with an adapter plug 28 connected to a power source. in this case,? ffl: The i-cord 6 is made up of four core wires.

Further, the plug 20 at one end is connected to the electrode pin 16 and electrode lead 19 of the socket 5 inserted therein. The adapter plug 28 is connected by inserting a pair of electrode pieces 29 into a power source. Note that an electronic circuit is incorporated inside the adapter plug 28.

Figure 4 shows the circuit configuration of the above-mentioned plant growing device. In Figure 4, 30 is an AC-[1G conversion section.
The C converter 30 converts the AC supplied from the AC power supply 31 into direct current and supplies it to the thermistor 4 via the resistor R. The thermistor 4 has a high resistance value when the temperature inside the case body l is low, and the 0 oscillator 32, which provides sufficient current from the AC-DC converter 30 to the oscillator 32, connects the control electrode of the thyristor SCH when a sufficient current is applied. A current is applied to the thyristor SCR to activate the thyristor SCR. As a result, current flows from the AC power source 31 to the heat generating resistor 12 and generates heat.

Also, when the temperature inside the case body l falls below a predetermined temperature,
The resistance value of the thermistor 4 becomes low and the AC-DC converter 30
Since sufficient current is not given to the oscillator 32, the oscillator 32 is turned off (the direction of oscillation is switched) and the operation of the thyristor SCR is stopped. This results in
Current cannot be returned from the AC power source 31 to the heating resistor 12,
The heating resistor 12 stops generating heat.

Therefore, according to the plant growing device configured as described above, since the planar heat generating member 2 is wrapped around the outer peripheral surface of the case body l, power can be supplied to the planar heat generating member 2 via the power cord 6. When the heat generating resistor 12 of the planar heat generating member 2 generates heat, the heat is transmitted to the loam inside through the case body 1, and the loam can be warmed satisfactorily. in this case.

Since the case body 1 is made of a thermally conductive synthetic resin, the heat generated by the heat generating resistor 12 of the planar heat generating member 2 can be efficiently transmitted to the loam inside. Moreover,
Since the planar heat generating member 2 is covered together with the case body 1 by a protective case 3 made of a heat insulating material, the generated heat can be applied to the loam through the case body 1 without escaping to the outside. Therefore, there is no need to heat it to a high temperature like in conventional garden cases, and it can be heated efficiently with less power consumption. In particular, since a thermistor 4 is sunk inside the case body l, this thermistor 4 detects the temperature of the loam inside the case body l, and when the temperature of the loam exceeds a predetermined value, it is transferred to the mi-shaped heating member 2. 9. Turn off the power to the Heat can be stopped. Therefore, the loam inside the case body is not heated to an unnecessarily high temperature and can always be kept at a constant temperature, which can extremely effectively promote seed germination and growth. .

Further, according to the above-described plant growing device, the planar heat generating member 2
Since it is formed in a band shape, it can be simply wrapped spirally along the mounting groove 7 formed on the outer wall of the case body l.
The planar heat generating member 2 can be easily attached to the case body 1. In particular, since the planar heating member 2 has a structure in which the heating resistor 12 is covered with the insulating member 13, there is no need to protect the heating element such as nichrome wire with a special protective member unlike in conventional heating units, and the structure is simple, and the entire device can be manufactured at low cost. In addition, the -L portion of the protective case 3 is inserted into the gap between the edge 10 of the case body l and the side wall of the case body l, so that when water is spilled from a water pitcher or the like, the protective case 3 It is possible to prevent wood from entering between the case body L and the side wall of the case body l, that is, the area of the planar heat generating member 2. Therefore, you can swim in the water with peace of mind.

Note that the present invention is not limited to the embodiments described above, and can be modified in various ways, for example.

The planar heat generating member 2 does not have to be in the form of a band, but may be in the form of a wide sheet, and there is no need to wrap it spirally around the outer circumferential surface of the case body 1; it only needs to be wrapped once around the case body 1. But that's fine. In addition, the case body l is not limited to a tabular cylindrical one, but may be a large box-shaped one, and the socket 5 does not need to be formed separately from the case body 1, but can also be formed integrally with the case body l. It is a pilgrimage. Moreover, the power cord 6 does not need to be removably connected to the socket 5 with the plug 20, but the plug and the socket may be integrally formed to connect the power cord 6 to the electrode bin 18 of the planar heat generating member 2.
18 and the electrode lead 19.19 of the thermistor 4 may be soldered directly.
Tf, it does not have to be the source 31, it may be converted to direct current using an AC-DC adapter etc., and the case body l
Temperature regulation within the chamber may be performed using a thermistor bridge circuit.

[Effects of the Invention] According to this M 1fl plant growing device, the planar heating element warms the loam inside the case body, so there is no need to heat the inside of the case body to a high temperature as in the conventional case.

Therefore, the power consumption is low, the loam can be efficiently heated, and the germination and r& length of seeds embedded in the loam can be favorably promoted. In particular, since the case body is made of a thermally conductive material, even if the planar heating element is wrapped around the outer wall of the case body, the heat L inside the case body can be satisfactorily warmed. In addition, since the planar heating element has a structure in which the heating resistor is covered with an insulating material, it is only necessary to wrap it around the outer surface of the case body, making it easy to attach to the case body. The structure is not complicated, is simple, and can be manufactured at low cost.
