JPH0852200A - Heat disinfecting apparatus for sand field - Google Patents

Abstract

PURPOSE:To provide a heat disinfecting apparatus for a sand field, which can sterilize sand in a sand field in a simple operation at a low cost. CONSTITUTION:A mounted rod 2 is mounted on the end of a handle rod 1 so as to be almost orthogonal each other. The mounted rod 2 is vertically provided with a multiplicity of heating rods 4 which will be stuck into sand 3 in a sand field. The heating rods 4 comprise wire-like rods. This apparatus is constituted so that a person grasping the handle rod 1 can move it in the sand field while keeping the heating rods 4 to be stuck by pulling or pushing force. The heating rods 4 includes a heater 5 which heats by passing electricity through and raises the surface temperature of the heating rods 4 up to high temperature that can sterilize germs or microorganisms inhabiting in the sand field.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sandbox thermal sterilizer for heating and sterilizing sand in a sandbox.

[0002]

2. Description of the Related Art In recent years,
Since children's and school children's play environment and objects are becoming stricter in terms of safety and hygiene, existing playground equipment is being reviewed.

Insects, bacteria such as microorganisms and Escherichia coli are present in the sand of the sandboxes provided in the playgrounds of parks, schools and kindergartens, and they are harmful to the human body.
Sterilization is emphasized.

At present, there are methods for disinfecting and sterilizing sand in sandboxes, such as a method of introducing a chemical agent and a method of exchanging with sterilized sand.

The former is simple, but the introduced chemicals may harm the human body remaining in the sand. In addition, the latter has a drawback that it is troublesome and expensive.

Further, a method of burying a heating device in the bottom of the sandbox in advance is conceivable, but it is also costly and causes a safety problem.

[0007] Therefore, an object of the present invention is to provide an extremely easy-to-use epoch-making heat disinfecting machine which can sterilize the sand in the sandbox by heating it uniformly with a simple operation.

[0008]

The gist of the present invention will be described with reference to the accompanying drawings.

A mounting rod 2 is provided at the tip of the gripping rod 1 and is substantially orthogonal to the lengthwise direction of the gripping rod 1, and a plurality of heating rods are inserted into the sand 3 of the sandbox. 4 are arranged side by side, and the heating rod 4 is formed into a fine rod, and the heating rod 4 is gripped by the gripping rod 1 and moved by a person to move the heating rod 4 in the sand. The heating rod 4 is constructed so that it can move in the sand while being stuck in the
The present invention relates to a sandbox thermal sterilizer characterized in that the heating rod 4 is provided with a heater 5 for heating the surface temperature of the above to a high temperature at which bacteria and microorganisms in the sand can be sterilized.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION A preferred embodiment of the present invention (how to carry out the invention) will be briefly described with reference to the drawings showing its function and effect.

The heater 5 is energized to heat the heating rod 4, the gripping rod 1 is gripped, and the heating rod 4 is attached to the sand 3 of the sandbox.
Stab into. For example, the gripping rod part 1 is moved or pushed to move the heating rod part 4 in the sand while the heating rod part 4 is pierced into the sand to sterilize fungi and microorganisms in the sand by contact heating or indirect heating by the heating rod part 4. To do.

[0012]

Embodiments of the present invention will be described with reference to the drawings.

At the tip of the grip rod 1 having the grip 1A at its base end, a mounting rod 2 is provided which is substantially orthogonal to the longitudinal direction of the grip rod 1.

A transformer 6 is arranged in the mounting rod portion, and a plurality of heating rod portions 4 constituted by heaters 5 are vertically arranged in a comb-teeth shape from the mounting rod portion 2 in parallel with each other. Wire with the container 6.

In this embodiment, the heating rod portion 4 itself is a ceramic heater which is heated by being energized.

[0016]

Since the present invention is configured as described above, the gripping rod is simply held and the heating rod is pierced into the sand of the sandbox.
For example, it is possible to sterilize the fungi and the like in the sand by the heat of the heating rods by simply moving the heating rods while pulling the gripping rods. As a result, it will become an epoch-making sandbox thermal sterilizer that can disinfect the sand efficiently and without cost.

For example, if this product is kept in stock at each park or kindergarten that has a sandbox, it can be used regularly, or when necessary, it is possible to easily manage the hygiene of the sandbox. It is a groundbreaking sandbox sterilizer that is extremely safe because it is extremely easy to use and does not use drugs.

Claims (1)

[Claims] 1. A gripping rod is provided with a mounting rod at the tip of the gripping rod substantially orthogonal to the lengthwise direction of the gripping rod, and a plurality of heating rods for piercing into the sand of a sandbox are juxtaposed to the mounting rod. The heating rod part is constructed in a fine rod shape, and the heating rod part is pierced into the sand by the force of a person pulling or pushing the gripping rod part in the sand. The heating rod is equipped with a heater that is configured to move inside and heats by heating to heat the surface of the heating rod to a high temperature at which fungi and microorganisms in the sand can be sterilized. Sandbox thermal sterilizer.
