Description

[Detailed description of the invention] [Field of industrial application] The present invention mainly relates to household electric washing machines.
In particular, it relates to an electric washing machine that has the function of bleaching and deodorizing the washing machine.

[Conventional technology]

Traditionally, laundry has not been sterilized or deodorized, and bleaching involves rinsing and then pouring a bleaching agent containing sodium hypochlorite or other ingredients into the water-filled washing tub of an electric washing machine. I was going by.

In conventional electric washing machines as mentioned above, if you do not perform sufficient rinsing such as dechlorination treatment after bleaching,
This will damage the fabric of your laundry and cause it to yellow over time. Also, bleaching naturally requires bleach, and unless you always have it on hand, you won't be able to bleach your laundry. Also, since bacteria are not removed from the laundry, if you dry it in the shade, bacteria on the laundry will multiply and cause discoloration. Also, since it is not deodorized, the odor transfers between laundry items, causing discomfort to underwear and the like.

As a solution to these problems,
As disclosed in the publication, outside air is sucked,
There are known washing machines that send the outside air to an ozone generator and eject ozone into the washing machine.

Furthermore, Japanese Patent Publication No. 38-1335 discloses that an ozone generator is placed at a suitable position on a machine and connected to the machine through a pipe.

[Problem that the invention attempts to solve]

However, in most homes, washing machines are placed in relatively humid places, and even if a pump sucks up the humid air and supplies it to an ozone generator, stable ozone cannot be generated. Therefore, the bleaching, sterilizing, and deodorizing functions could not be fully demonstrated.

The present invention was devised to solve the above-mentioned problems, and aims to improve the ability to generate ozone stably even in humid and dusty areas.

[Means for solving problems]

The washing machine of the present invention that solves the above problems includes an air filter that filters outside air, an electric heater that heats and dries the air, an air pump for suction, an ozone generator that generates ozone based on the air, and a washing machine that uses the ozone to wash the ozone. It consists of an aeration pipe that blows into the water in the tank to dissolve it.

[Effect]

According to this invention, by filtering outside air with an air filter to prevent floating dust from entering the ozone generator, and drying the air with an electric heater, the air with a relative humidity of 50% or less is supplied to the ozone generator. ozone and give it the ability to generate stable ozone.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

The figure is a partially cutaway sectional view of an electric washing machine showing an embodiment of the present invention. In the figure, 10 is an electric washing machine, 20 is an air pump, 30 is an ozone generator, and 4
0 is an air diffuser, 50 is an air filter, and 60 is an electric heater. Electric washing machine 10 according to the present invention
is a conventional electric washing machine with an air pump 20, an ozone generator 30, an air diffuser 40, and an air filter 5.
By arranging electric heaters 60 at predetermined positions, stable ozone is generated to bleach, sterilize, and deodorize laundry. 11 is a washing machine main body, 12 is a washing tub, and 13 is a dehydration tub, and the electric washing machine 10 is as shown in the figure.
This fully automatic electric washing machine has a double structure of a washing tub 12 fixed in a hollow part in a washing machine body 11 and a dehydration tub 13 rotatably attached to the hollow part. Reference numeral 14 denotes a motor provided at the bottom of the washing tub 12, and the motor 14 rotates the dewatering tub 13 during rinsing. On the other hand, 15 is a pulsator installed at the bottom of the dehydration tank 13,
During washing, the pulsator 15 is activated by the motor 14.
rotates to generate water flow for washing. In addition, there are many holes 141 on the side of the dehydration tank 13, so when washing and rinsing, the dehydration tank 13
There is always water in the tank. Although not shown, the dehydration tank 13 contains laundry to be bleached, sterilized, and deodorized. 21 is a connecting pipe, and an ozone generator 30, an electric heater 60, an air pump 20, and an air filter 50 are connected in sequence through the connecting pipe 21. The air pump 20 is a pump that sucks outside air and sends it to the ozone generator 30 through a pipe 21, and is attached to a mounting plate 22 fixed to the inner surface of the washing machine main body 11. The ozone generator 30 uses outside air introduced from the air pump 20,
This is a device that generates ozone. This device generates this by applying a high voltage inside to cause a silent discharge, and by passing air through it, converting some of the oxygen in the outside air into ozone. 41 is a connecting pipe, 42 is an aeration part, and the aeration pipe 40 is equipped with a connection pipe 41 that guides ozone to the washing tub 12, and an aeration part 42 having a large number of micro holes attached to the tip thereof, This is for blowing ozone generated by the ozone generator 30 into the soapy water in the washing tub 12 and dissolving it. The ozone generator 30 and the aeration pipe 40 are connected via a connecting pipe 41. The air filter 50 is a device for filtering floating dust in the air as a dust removal means. The electric heater 60 is a normal heat source device that heats the air by applying electricity and lowers the relative humidity of the air. The ozone generator 30 and the air pump 20 are controlled by a control circuit of the electric washing machine 10 (not shown), and are configured to send ozone to the aeration pipe 40 when rinsing laundry.

In this way, ozone is introduced into the washing tub 12, but the atmosphere in which the washing machine is generally placed is often humid and has a lot of dust. As in the past, humid air is sucked by the air pump 20 and the ozone generator 3
If it is sent to 0, the discharge current there increases and the efficiency of silent discharge decreases, resulting in a decrease in the amount of ozone generated. If dusty air is sent in the same way, dust will accumulate in the ozone generator 30 over time, and current will begin to flow through the dust, which will similarly reduce the amount of ozone generated.

Therefore, in the present invention, by removing dust from the air with an air filter 50 and heating the air with an electric heater 60, the air sent to the ozone generator 30 has less dust and has a lower relative humidity, making it stable. Ozone is generated and performs the functions mentioned above (bleaching, sterilization, deodorization).

[Effect of idea]

As described above, according to the present invention, a stable amount of ozone generation can be ensured, and an electric washing machine with additional functions such as bleaching, sterilization, and deodorization can be realized at low cost.
