Description

vacuum cleaner

The present invention relates to a cleaner, and more particularly, to a portable vacuum cleaner having a detachable cleaning module.

BACKGROUND ART In general, a vacuum cleaner is a home appliance that sucks up small garbage or dust by sucking air using electricity and fills a dust bin in the product, and is commonly referred to as a vacuum cleaner.

Such cleaners may be classified into manual cleaners for cleaning while a user directly moves the cleaner, and automatic cleaners for performing cleaning while driving by itself. Manual cleaners may be classified into canister-type cleaners, upright cleaners, handheld cleaners, and stick-type cleaners according to the shape of the cleaner.

In household cleaners, canister-type vacuum cleaners have been widely used in the past, but recently, handheld vacuum cleaners and stick vacuum cleaners, which provide convenience in use by integrally providing a dust bin and a cleaner body, have been widely used.

The main body of the canister type vacuum cleaner is connected to the intake by a rubber hose or pipe, and in some cases, a brush can be inserted into the intake.

The Hand Vacuum Cleaner maximizes portability and is light in weight, but has a short length, so the cleaning area may be limited while sitting. Thus, it is used to clean localized areas, such as on a desk or sofa, or in a car.

The stick vacuum cleaner can be used standing up, so you can clean without bending your back. Therefore, it is advantageous to clean while moving a large area. If the handheld vacuum cleaner cleans a narrow space, the stick type cleaner can clean a wider space and can clean high places that are out of reach. Recently, a stick cleaner is provided in a module type, and the cleaner type is actively changed and used for various objects.

There are two main types of floor cleaning: dry cleaning and wet cleaning. Dry cleaning is a method of cleaning by sweeping or sucking dust, and a conventional vacuum cleaner corresponds to this. Wet cleaning is a method of cleaning by wiping off dirt with a damp cloth. In addition, there is also a method of generating and spraying high-temperature steam during wet cleaning to sterilize and clean.

Recently, as various materials are used in construction, the cleaning method has also diversified. Conventionally, the floor is mainly made of wood, and since wet cleaning is impossible, only dry cleaning is performed. However, in recent years, the floor is made of various materials such as steel plate or marble, and it is possible to perform wet cleaning.

Conventionally, a dry cleaner is used for dry cleaning, and a wet cleaner is used for wet cleaning. However, it is inconvenient to purchase two types of vacuum cleaners in order to clean various types of floors. In order to solve the above problems, one main body, a dry cleaning module and a wet cleaning module are provided, the dry cleaning module is mounted on the main body for dry cleaning, and the wet cleaning module is mounted on the main body for wet cleaning. method was studied.

The wet cleaning module includes a water container for storing water, a heater for generating steam by heating water, and a mop for wiping the floor by receiving water or steam. Each of the above parts is preferably composed of one assembly to facilitate replacement. For example, when a water container or heater is disposed in the main body, there is a problem in that cleaning becomes inconvenient due to unnecessary parts when the dry cleaning module is mounted on the main body. The heater is preferably disposed in the wet cleaning module rather than the main body.

As prior art 1, there is an invention related to a heater device and a vacuum cleaner having the same. The vacuum cleaner according to the prior art 1 includes a heater device including a heating casing generating steam by receiving water from a water supply tank.

According to the prior art 1, the water tank is detachably installed in the main body instead of the nozzle assembly. In addition, a heater device for generating steam is also installed in the main body instead of the nozzle assembly. In the prior art 1, in order to design the size of the nozzle assembly to be smaller and at the same time to secure sufficient storage capacity of the water container, the water container and the heater device were installed in the main body rather than the nozzle assembly.

The case of prior art 1 does not have a separate ventilation hole. Therefore, the heat of the heater remains inside the case and does not dissipate to the outside. When the heat reaches the pump, the pump may overheat and fail. Alternatively, there is a problem that the heat may damage other precision parts installed inside the case.

In addition, the prior art 1 has a problem that the water tank is installed in the main body, and the center of gravity is high, making it difficult to operate. In addition, since the distance between the heater and the mop is long, heat loss occurs while steam flows to the mop, and sensitive electronic equipment is damaged due to the lost heat.

As prior art 2, there is an invention related to a steam cleaner. In the prior art 2, the steam generation efficiency can be increased while the structure of the steam generator is simplified, and the cleaning efficiency is improved by rotating the mop to which steam is supplied from both left and right sides.

In prior art 2, a plurality of ventilation holes are formed on the rear surface of the case. However, since the ventilation hole cools the heat of the heater, the thermal efficiency of the heater may decrease as the heater is supercooled, and the air that absorbs the heat of the heater rises, causing the pump to overheat.

Also, the water tank and heater of the prior art 2 are installed in the cleaner body rather than the cleaning module as in the prior art 1, and thus have the same problems as the prior art 1.

As prior art 3, there is an invention related to a steam wet mop vacuum cleaner. In the prior art 3, the brush around the bucket rotates to guide the dust to the central suction port, thereby enabling the steam wet mop to be cleaned while keeping the steam wet mop clean.

However, prior art 3 also has a problem in that, like prior art 1, since no ventilation hole is formed in the case, the heat of the heater remains inside the case and the heat may damage other precision parts installed inside the case.

In addition, there is also a problem in that the storage capacity of the water container is reduced as the height of the water container is also lowered in order to lower the height of the cleaning module.

The problem to be solved by the present invention is devised to solve the problems of the above-mentioned prior literature. That is, as described above, a heater generating steam from water is essentially disposed in the wet cleaning module, and the heat emitted from the heater is transferred to the surface of the cleaning module to heat the surface of the cleaning module to prevent the user from getting burned. It is to provide a cleaner that does.

Another problem to be solved by the present invention is to provide a cleaner that prevents heat emitted from a heater from being transferred to sensitive electronic devices such as motors or sensors placed nearby and damaging the electronic devices.

Another problem to be solved by the present invention is to provide a cleaner capable of rapidly cooling the equipment when heat emitted from a heater reaches other equipment.

Another problem to be solved by the present invention is to provide a cleaner that blocks heat emitted from a heater from reaching other equipment and keeps the heat around the heater.

Another problem to be solved by the present invention is to provide a vacuum cleaner that prevents heat or steam emitted from a mop from flowing into a suction passage to overheat an extension tube or overheat other parts of the main body through the extension tube.
