Description

[Detailed description of the invention] [Technical field of the invention] The invention is an electric blanket, an electric carpet, or an electric blanket, in which a heater that generates heat when energized is insulated and arranged inside the body. This relates to electric heating equipment.

[Prior art]

The conventional electric heating devices such as electric blankets, electric carpets, and electric blankets have poor washing resistance due to the fabric itself, and have problems such as shrinkage of the fabric, deterioration of the appearance of the fabric, and low strength. Along with being,
Since the electrical parts inside the main body were not waterproof, it was generally impossible to wash them.

However, in recent years, there has been a growing demand for washable electric blankets and other products in the market, and there has been a demand for products that can be easily washed at home.

Therefore, in order to make the above-mentioned electric heating equipment washable, we developed fabrics with less shrinkage, increased strength, and
Although cord openings are already in use with water-resistant construction, etc., washing in this case must be done by means other than dry cleaning, and manufacturers recommend dry cleaning for these electric heating appliances. At the same time, some measures must be taken to prohibit the reuse of items that have been dry cleaned.

In other words, for items such as electric blankets in which the heater, temperature detection wire, etc. are covered with a plastic material, dry cleaning solutions such as perchlorethylene will harden the outer covering of the heater and cause it to become thinner overall. There is a great risk of insulation failure due to insufficient insulation wall thickness.In addition, the impedance characteristics of the temperature detection wire will suddenly change, causing the temperature of the blanket to rise and causing burns etc. during use. This is because the danger becomes greater.

For this reason, electric heating equipment that has been designed to be dry-cleanable has a cord-opening case that melts when dry-cleaned, which is placed inside the cord-opening case installed at a predetermined position of the heating equipment. JP-A-59-205178 relates to a heating device equipped with a detection body that detects whether or not dry cleaning has been performed by preventing the case from melting and, as a result, preventing electricity from flowing to the heater.
Detection for detecting whether dry cleaning has been performed at a predetermined position on the main body of an electric heater such as an electric blanket or an electric carpet, in which a heater that generates heat when energized is insulated and disposed in the main body. Utility Model Application No. 60-145593 was devised regarding an electric heater equipped with a heater body, and the former invention melts the resin of the cord opening case when dry cleaning is performed, thereby preventing electricity from flowing to the heater. This is a technology that detects whether dry cleaning has been performed by doing so, and the latter technology detects that dry cleaning has been performed by the disappearance of paint and ink when dry cleaning has been performed. It's technology.

However, in both of the above two known examples, by providing a detector to detect whether or not dry cleaning has been performed, it is possible to prevent danger to the user in the event of dry cleaning by mistake, and to prevent problems with heating equipment. The purpose is to easily determine whether the heating equipment has been dry cleaned or not, and it does not actively inform the user that dry cleaning is prohibited for the heating equipment. If you dry clean your clothes by mistake,
There is a problem in that the user is not immediately made aware of the reason why the warming device is no longer usable.

In addition, as proposed in Utility Model Application Publication No. 174192/1983, a notice is placed on the top of the plug case that is integrally attached to the body of the electric heating device to inform the user that reuse of the body is prohibited after dry cleaning. Even on the plug case of electric heating equipment, which has a display part for recognition and is covered with a molten film that can be melted and destroyed by dry cleaning solvent, it is actively made clear that this heating equipment is prohibited from dry cleaning. It's not something to make known.

Furthermore, the display board provided on the surface of the connector provided on the electric heating device includes a resin board and display members showing display contents at the top and bottom of the resin board, and the display member on the top of the resin board is dry-cleanable. Japanese Utility Model Application No. 61-49994 has been devised regarding a display board for a connector that uses a display member that can be dissolved by a solvent, and similar known examples are explained in FIGS. On the top surface of the plug case 2 that is integrated into the main body 1 of the electric heating device,
A display 5 is provided to make the user aware that "dry cleaning is prohibited."

A plurality of pin contacts (not shown) are provided inside the plug case 2, and a temperature detection line 7 and a heater 9 are connected to one end of the pin contacts.

The other end of the pin contact extends toward the opening 10 of the plug case 2, and a plug (not shown) with a built-in mating contact is inserted into this pin contact from the opening 10 of the plug case 2 to provide electricity. It is now possible to make connections.

Therefore, this display body 5 is made of styrene resin that is dissolved in a dry cleaning solvent such as perchlorethylene. On the bottom of the main body 1, the words "Do not use" are printed, and on the bottom of the groove 11 where "Do not use" is printed, an indicator 5 with the words "Do not dry clean" is attached with adhesive or the like. It is installed so that it does not come off.

When such a heating device is dry cleaned, the display body 5 is melted and destroyed by the dry cleaning solvent, so the words "Do not use" on the bottom of the groove 11 of the plug case 2 are exposed. This allows the user to be aware of the prohibition of reuse.

However, in this case as well, due to the mistaken dry cleaning, the words "Do not dry clean" melt and disappear together with the display 5, leaving the words "Do not use" exposed.
The user may not know why the use of the warming device has been prohibited, and there is a possibility that the user may forcefully reuse the warming device without fully understanding the situation, which is very dangerous.

[Purpose of invention]

The present invention was developed to solve the above-mentioned conventional problems, and includes a display that actively encourages users not to dry-clean electric heating equipment, as well as a display that actively encourages users not to dry-clean electric heating equipment. The purpose is to display that reuse is prohibited and to make the user immediately aware that the reason for prohibiting reuse is that the product has been dry cleaned.

[Structure of the idea]

In order to achieve the above object, the electric heating device of the present invention has a mark on the main body of the electric heating device or the surface of its plug case at an appropriate position to the effect that ``dry cleaning is prohibited'' cannot be erased by dry cleaning. It is constructed by attaching a body and then attaching a sign stating ``Use is prohibited'' under an opaque body that disappears when dry-cleaned, which is placed in a separate location from this sign, and that the electric heating device is not in constant use. It is possible to appeal to people that dry cleaning is prohibited, and
If the electric heating device is dry cleaned by mistake, the user should be reminded not to use it again, and the display that says ``Do not dry clean'' will disappear even after dry cleaning. Therefore, the user can immediately recognize the reason for the "prohibition of use".

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. In each embodiment and the conventional example shown in FIGS. 10 and 11, the same parts are indicated by the same part numbers.

First, the electric heating device of the first embodiment of the present invention shown in FIGS. 1, 2, 3, 4, and 5 is the electric heating device shown in FIG. 1 made of blanket fabric or the like. It has a main body 1 and a plug case 2 provided on the main body 1.

A plurality of pin contacts 3 are provided inside the plug case 2 as shown in FIGS. A temperature detection line 7 and a heater 8 are connected, and the other end of the pin contact 3 is directed toward an opening 10 of the plug case 2.

This plug case 2 includes a plug 2 shown in FIG.
0 is inserted through the opening 10 of the plug case 2, and the pin contact 3 is connected to a mating contact, thereby establishing an electrical connection.

Further, a long groove 21 is formed in a part of the upper surface of the plug case 2, extending from the opening 10, and the long groove 21 receives a protrusion 23 formed in a part of the upper surface of the plug 20. The long groove 21 and the protrusion 23 allow the plug case 2 and the plug 20 to be inserted in the correct position.

Therefore, a first opaque body 25 is placed at an appropriate position on the surface of the plug case 2 provided in this electric heating device.
The opaque body 25 is made of synthetic resin and has the same color as the plug case 2, but it cannot be dissolved in a dry cleaning solvent such as perchlorethylene. The opaque body 25 is formed of a styrene plate or the like so that the opaque body 25 itself disappears, and is attached to the groove 11 shown in FIG. 3 formed on the top surface of the plug case 2.

Furthermore, an indicator 13 is formed on the surface of this groove 11, which is recognized when dry cleaning is performed, and this indicator 13 is made of ink that does not dissolve and disappear even during dry cleaning. Therefore, for example, "Use prohibited" is printed, as shown in FIG. 4.

Furthermore, when sewing the hem cloth 30 provided on the peripheral edge of the main body 1 of this embodiment 1 as shown in FIG.
A cloth display 33 is attached to the 0, and this display 33 has a message saying ``Dry cleaning is prohibited.''
For example, a display indicating "Dry Cleaning Prohibited" is provided, and the display on the display body 33 is printed using ink or the like that cannot be erased by dry cleaning.

In the electric heating device of Embodiment 1 of the present invention configured as described above, the user and the laundry company always recognize the text display, for example, "Dry cleaning prohibited" displayed on the display 33, and dry cleaning is prohibited. can be prevented from occurring.

Furthermore, if dry cleaning is performed by mistake, the opaque body 25 shown in FIGS. 2 and 3 will be dissolved by the dry cleaning solvent and the opaque body 25 shown in FIGS. 4 and 5 will be removed from the groove 11 of the plug case 2. Since the display body 13 formed on the bottom surface of the groove portion 11 is exposed, the user etc. can see the display body 13.
You will see the words ``Do not use'' printed on the
I am aware that it cannot be reused, but at that time, the words "Do not dry clean" on the display 33 of the main body 1 do not disappear even with dry cleaning and are still displayed, so I do not want to use them again. You will immediately recognize the reason.

In addition, if you write a note on the display 33 or in an appropriate place to the effect that when dry cleaning is performed, the words ``Do not use'' will appear on the plug case 2, the reason for ``Do not use'' will be made clear. It can be done.

Further, in the first embodiment, the indicator 13 is attached to the plug case 2, but it is printed on the bottom surface of the groove 11 of the plug case 2 using a hot stamp with ink that does not disappear when dissolved by a dry cleaning solvent. However, the display body 13 and the display body 33 may be covered with the opaque body 25, and the display body 13 and the display body 33 may be placed at different appropriate positions on the surfaces of the main body 1 and the plug case 2 of the electric heating device. The location is not limited.

Next, FIG. 6, FIG. 7, FIG. 8, and FIG. 9 show a second embodiment of the present invention. The display body 40 is engraved with a stamp, and the words "Do not use" are formed on the display body 40. The display body 40 is covered with an opaque body 25, and dry cleaning is not allowed. When the opaque body 25 is removed, the opaque body 25 dissolves and disappears, and the display body 40 that displays "Do not use" is exposed as shown in Figure 8 from the state shown in Figure 6, and the user etc. recognizes this display. You can confirm that it cannot be reused.

In addition, "Dry cleaning prohibited" sign 3
5 may be applied to the surface of the plug case 2 at a location different from the display body 40 using ink or the like that does not dissolve in dry cleaning solvents. 4
0, it is also effective to attach a display 33 as shown in FIG. 1 to the main body 1 in the first embodiment to ensure that the user is careful.

Please note that "dry cleaning prohibited" sign 3
3 and 35 may be printed on a resin plate or a film plate that will not disappear when dissolved by dry cleaning, and this film plate may be adhered to the upper surface of the plug case 2 with an adhesive.

[Effect of idea]

As explained above, the electric heating device of the present invention has a label that actively reminds the user not to dry clean it, which has the effect of preventing the heating device from being washed incorrectly. Yes, if you accidentally dry clean the product, a sign prohibiting its use will be immediately displayed, and the “Do not dry clean” sign will not be dissolved by the dry cleaning solvent, so it will become “Do not use”. This has the effect that the user, etc. can immediately recognize the reason for the change.

Please note that the "Do not use" display that appears after washing the main unit with dry cleaning solvent,
For example, by covering the main body or plug case with an opaque material that is the same color as the main body or plug case and disappears by dissolving when dry-cleaned, the opaque material will act as a display screen, making the display invisible during normal use. The appearance of the plug case can be improved.

Therefore, by adopting the present invention, it is possible to prevent the misuse of electric heating equipment, and even if dry cleaning is carried out by mistake, the meaning of the "Do not use" sign that is displayed can be changed. The reason for this is easy to understand, and there is an effect that troubles such as reuse after dry cleaning can be prevented.

Also, in the season when electric heating equipment is not used,
When I take it to be cleaned, or when I use it during the season when electric heating equipment is used, I always look at the plug case 2 to unplug and plug it in, so it's important to note that dry cleaning is prohibited. If the "Use Prohibited" display is placed on the surface of the plug case, these characters will be noticed, so it is effective to provide these display positions on the surface of the plug case.
