Definitions

  • the present disclosure relates generally to a plant cultivation apparatus capable of cultivating plants while automatically performing air circulation, light supply, and water supply.
  • a plant cultivation apparatus is a device cultivating plants in a seed state.
  • the plant cultivation apparatus has been provided in various forms that may easily cultivate plants indoors.
  • the indoor plant cultivation apparatus may be classified into a hydroponic cultivation apparatus and a soil cultivation apparatus.
  • the soil cultivation apparatus is a device using a cultivation method of planting a plant (or seeds) in soil of a pot and continuously supplying water to the pot, as proposed in Korean Patent No. 10-1400375 (document 1), Korean Utility Model Registration No. 20-0467246 (document 2), and Korean Utility Model Registration No. 20-0465385 (document 3).
  • the soil cultivation apparatus may further improve growth of a plant due to nutrients in the soil and increase the growth rate of the plant.
  • the apparatus is configured such that, a culture substrate and a water storage are spaced apart from each other, so water in the water storage is supplied into the soil in the culture substrate through an absorbing member.
  • a cultivation space is inevitably small and water stored in the water storage is easily contaminated due to the nutrient solution.
  • the apparatus is configured such that, water supply is performed in a way that water is periodically sprayed onto the soil (plug tray, cultivation container), so a nutrient solution splashes to the surroundings (inside of cultivation room or door) to cause contamination. Therefore, water stored in a tank (nutrient tank, holdup tank) is easily contaminated due to the nutrient solution.
  • a bed is configured not to be taken out from the apparatus, so it is difficult to perform maintenance such as washing, etc. Thus, contamination in the apparatus easily occurs.
  • a cultivation shelf is configured to be taken out from the apparatus, so maintenance as needed is possible.
  • the cultivation shelf should be taken out together with a storage container, the cultivation shelf should be washed by separating and taking out the storage container therefrom, which is inconvenience.
  • the longer the storage container is in the taken-out state the longer a plant cultivated in the cultivation shelf is exposed to the outside environment, which is not good for growth of the plant, and further storage of the plant is difficult.
  • the present disclosure has been made keeping in mind the above problems occurring in the related art, and the present disclosure is intended to provide a new type plant cultivation apparatus.
  • the plant cultivation apparatus is configured to prevent residual water, so that contamination or odor in a cultivation room caused by the residual water is prevented.
  • Another objective of the present disclosure is to provide a new type plant cultivation apparatus, wherein a bed cover where a pod is seated is separated from a bed where supply water is supplied, so that washing or maintenance of the bed is easily performed without separating the pod from the bed.
  • a further objective of the present disclosure is to provide a new type plant cultivation apparatus, wherein the plant cultivation apparatus is configured to precisely supply the supply water to the bed without overflowing around the bed when the supply water is supplied into a water supply groove of the bed.
  • the plant cultivation apparatus of the present disclosure may include a bed cover that is provided to open an upper surface of the bed. Whereby, the bed may be washed without separating a pod from the bed.
  • the bed of the plant cultivation apparatus of the present disclosure may be positioned above a water supply module.
  • the water supply module of the plant cultivation apparatus of the present disclosure may be positioned a bottom in a cabinet.
  • the bed may have a water reservoir at either circumferential wall surface thereof.
  • the bed may have a water supply groove therein.
  • the bed cover may have a seating groove therein.
  • the seating groove may have a penetration hole.
  • the bed cover may be configured to open the upper surface of the bed while rotating from the bed. Whereby, when a user needs, the user can open the upper surface of the bed and wash the bed.
  • the bed may be provided to be taken out while sliding back and forth from a cultivation room in the cabinet. Whereby, the bed may be taken out from the cultivation room together with the bed cover and the pod.
  • the bed may have a supply water flow path. Whereby, supply water supplied from the water reservoir may be stored in the water supply groove.
  • the supply water flow path may be provided on the upper surface of the bed. Whereby, the supply water flow path may be integrally formed with the bed.
  • the supply water flow path may be configured to be inclined downward as the supply water flow path goes from the water reservoir to a surface level of the water supply groove. Whereby, the supply water may be smoothly supplied to the water supply groove.
  • bank parts may be provided on the upper surface of the bed at opposite sides of the supply water flow path. Whereby, the supply water flowing along the supply water flow path may be prevented from overflowing from the bed.
  • the water reservoir may be configured as a container body that protrudes outward from a rear wall surface of the bed and is open at an upper surface thereof. Whereby, the water may be stably supplied.
  • a first placing groove may be provided a portion between the bed and the water reservoir.
  • the center of rotation of the bed cover may be provided outside the bed so that the upper surface of the bed may be completely opened.
  • the first placing groove may include a linear portion and a bottom portion. Whereby, a first placed protrusion rotating while being seated on the first placing groove may be prevented from deviating from a regular position thereof during rotation.
  • the bottom portion of the first placing groove may be rounded. Whereby, when the bed cover rotates, the bottom portion may support the first placed protrusion to rotate smoothly from the first placing groove.
  • the bottom portion of the first placing groove may be formed in semicircular groove. Whereby, when the bed cover rotates, the bottom portion may support the first placed protrusion to rotate smoothly from the first placing groove.
  • the linear portion of the first placing groove may be higher than a height of the bottom portion. Whereby, when the bed cover rotates, the linear portion may prevent the first placed protrusion from deviating from the first placing groove.
  • the first placed protrusion may be rounded. Whereby, when the bed cover rotates, the first placed protrusion may rotate smoothly from the first placing groove.
  • an end of the first placed protrusion may be rolled inward to be rounded. Whereby, the first placed protrusion may be easily manufactured.
  • a second placed protrusion may protrude downward from a front edge of the bed cover. Whereby, the bed cover may be stably seated on the bed.
  • a second placing groove may be depressed from a front circumferential portion of the bed. Whereby, the bed cover may be prevented from moving back and forth from the bed.
  • the plant cultivation apparatus of the present disclosure may have various effects as follows.
  • the plant cultivation apparatus of the present disclosure may be configured as the structure for supplying as much water as necessary, so that the supply water does not remain in the bed. Thus, contamination or odor in the cultivation room caused by the residual water can be prevented.
  • the bed cover where the pod is seated may rotate while being tilted from the bed where the supply water is supplied so that the upper surface of the bed may be opened without taking out the bed from the cultivation room or separating the bed cover and the pod from the bed.
  • washing or maintenance of the bed can be easily performed.
