[0049] FIG. 2 is a perspective view showing a cultivation bed (100) in a plant cultivation device according to one embodiment of the disclosed content, and FIG. 3 is a perspective view showing a cultivation bed (100) and a sensor in a plant cultivation device according to one embodiment of the disclosed content.

[0050] As illustrated in FIGS. 2 and 3, the cultivation bed (100) includes a cultivation container (110), a handle (120), and a tray (130). As previously described, the cultivation container (110) is in the form of a container having a wide bottom surface and an open top surface. A growing medium can be contained inside the cultivation container (110), and seeds are planted in the growing medium to germinate and grow crops. The growing medium can be made in various forms, and different types of growing media can be stacked and contained inside the cultivation container (110).

[0051] The cultivation container (110) is housed in a tray (130). In addition, at least a portion of the bottom surface of the cultivation container (110) may be formed with an opening that is open to communicate with the bottom. The opening is positioned above the water supply section (136) and serves as a passage for water from the water supply section (136) to flow into the cultivation container (110). A wick may be further included inside the cultivation container (110), with its lower end positioned adjacent to the opening and its upper end facing the inside of the cultivation container (110). The wick is made of a porous material and has the property of absorbing water well. Therefore, water flowing into the opening can be evenly supplied to the growing medium inside the cultivation container (110) through the wick.

[0052] The tray (130) forms a space that can be used for cultivation containers (110) and can be formed in the shape of a drawer. A handle (120) is formed on one side of the tray (130), and the handle (120) can be shaped so that a user can grip it.

[0053] And a water supply section (136) may be provided in the tray (130). The water supply section (136) is formed by being carved out so that water can be stored in at least a part of the tray (130). The water supply section (136) may form a predetermined path and is formed so that a cultivation container (110) is seated on the upper part of the water supply section (136). An inlet section (132) is formed on one side of the tray (130) at a position higher than the water supply section (136). The inlet section (132) is a place where water is supplied and is formed protruding from one side of the tray (130), and when water flows in from the top, it is sent to the water supply channel (134). The water supply channel (134) is a channel connecting the inlet section (132) and the water supply section (136). Since the inlet section (132) is formed at a higher position than the water supply section (136), water supplied to the inlet section (132) flows to the water supply section (136) along the water supply path (134).

[0054] Additionally, the cultivation bed (100) can be inserted into or withdrawn from the cultivation space (14) by sliding in one direction on the shelf (200). At least one rail (140) may be formed on the underside of the cultivation bed (100), and the rail (140) interferes with the shelf (200) to allow the cultivation bed (100) to be moved by sliding in one direction.

[0055] And, the shelf (200) to be described later includes a water level sensor (210). The water level sensor (210) is located vertically below the water supply unit (136) while the cultivation bed (100) is placed on the shelf (200). The water level sensor (210) is a non-contact sensor that measures the height of the water accumulated inside the water supply unit (136).

[0056] FIG. 4 is a partial cross-sectional view showing the arrangement relationship between the water supply unit (136) and the sensor in a plant cultivation device according to one embodiment of the disclosed content, and FIG. 5 is a partial cross-sectional view showing the spacing between the water supply unit (136) and the sensor in a plant cultivation device according to one embodiment of the disclosed content.

[0057] As illustrated in FIGS. 4 and 5, the water level sensor (210) is positioned vertically below the water supply unit (136) while the cultivation bed (100) is seated on the shelf (200). The water level sensor (210) may be a sensor that measures capacitance. The water level sensor (210) measures the amount of water contained within the water supply unit (136) by measuring the capacitance of the water supply unit (136). The water level sensor (210) is spaced apart from the bottom surface of the water supply unit (136), which is the bottom surface of the cultivation bed (100), by a predetermined distance (d) so as not to come into contact with or interfere with the bottom surface of the cultivation bed (100) during the process of the cultivation bed (100) sliding and being seated on the upper part of the shelf (200).

[0058] FIG. 6 is a partial cross-sectional view illustrating the state in which a pressure projection (138) is formed on the bottom surface of a water supply section (136) in a plant cultivation device according to one embodiment of the disclosed content.

[0059] As illustrated in FIG. 6, a pressure projection (138) protruding downward can be formed on the bottom surface of the water supply unit (136). At this time, the water level sensor (210) is coupled to the shelf (200) so that its height can be adjusted. Specifically, the water level sensor (210) is fixed to the shelf (200) via an elastic member (212), and when a force applying pressure from above is applied to the water level sensor (210), the height of the water level sensor (210) decreases. Then, when the force that applied pressure to the water level sensor (210) is removed, the water level sensor (210) rises back to its original position.

[0060] Accordingly, the pressure projection (138) formed on the bottom surface of the water supply section (136) presses the water level sensor (210) from top to bottom and causes the water level sensor (210) to be spaced apart from the bottom surface of the water supply section (136) by a certain distance (d).

[0061] FIG. 7 is a cross-sectional view illustrating a state in which a cultivation bed (100) is withdrawn from a shelf (200) in a plant cultivation device according to one embodiment of the disclosed content, and FIG. 8 is a partial cross-sectional view illustrating a state in which a cultivation bed (100) is slidably seated on a shelf (200) in a plant cultivation device according to one embodiment of the disclosed content.

[0062] As illustrated in FIG. 7, the bottom surface of the water supply section (136) may be formed to be inclined in one direction. Accordingly, when the cultivation bed (100) slides in one direction on the shelf (200), the bottom surface of the water supply section (136), which is formed as an inclined surface, gradually presses against the water level sensor (210), and the water level sensor (210) is pushed downward as it comes into contact with the inclined surface of the bottom surface of the water supply.

[0063] Accordingly, during the process of mounting the cultivation bed (100) on the shelf (200), the water level sensor (210) is not obstructed from the path of the cultivation bed (100), and the water level sensor (210) can be spaced apart from the water supply unit (136) at a predetermined distance.

[0064] FIG. 9 is a flowchart illustrating the process of residual water detection and water supply in a plant cultivation device according to one embodiment of the disclosed content.

[0065] As illustrated in FIG. 9, a plant cultivation device according to one embodiment of the disclosed content measures the amount of water stored in the water supply unit (136) in real time by performing a sensor operation step (S10). The sensor operation step (S10) first detects (S20) whether the cultivation bed (100) is in the correct position. If the cultivation bed (100) is not in the correct position, it notifies the user that the cultivation bed (100) is not properly installed through a signal output (S22). Then, if the cultivation bed (100) is in the correct position, it performs a residual water amount detection step (S30). By detecting the residual water amount, it determines (S40) whether water supply is needed and performs water supply (S50) or continues to detect the residual water amount.

[0066] Although embodiments of the disclosed content have been described above together with the drawings, this is illustrative and the content disclosed in the drawings is not limited to the aforementioned embodiments. It is obvious to those skilled in the art that embodiments of the disclosed content can be modified within the scope of the technical concept of the disclosed content. Furthermore, even if the operation or effect according to the configuration was not explicitly described while describing an embodiment of the disclosed content, it is natural that effects predictable by said configuration should be recognized.
