Heating mat for a pet {Heating mat for a pet}

The present invention relates to a heating mat for a pet, and more particularly, to a heating mat for a pet which can realize a front heating effect even with a simple structure, has excellent durability and waterproof performance, .

In recent years, as the pet has gradually increased its status as a human companion animal, advances have been made in clothing, food, housing space and household goods for pets, and research and development of various pet products have been actively carried out Trend.

Among these pet products, a heating mat for pets which is intended to provide a warm and comfortable floor environment for pets in a low indoor / outdoor temperature environment is commercially available.

In the past, when the outdoor temperature and the indoor indoor temperature are low, and the pet feels cold and the pet feels uncomfortable, the temperature of the room may be raised or the pet body may be kept warm by using various heat- However, when a pet is living outdoors or in a house where it is difficult to provide a warm environment, it is heated by an auxiliary heater. In this case, a heating mat is mainly used as a heating mat. Thereby increasing the temperature.

In the current market, pet heat mats are a type of heat mats using resistance heat of nichrome heating wires, which have a similar structure to those used for outdoor use by humans. Such a heat-generating mat has a basic structure in which nichrome wire coated with an insulating coating is fixedly arranged at a predetermined interval and then connected to a power line to energize the battery, and then heat is generated. Then, the heat-resistant mat is wrapped with a synthetic cloth, And then use it.

In the case of this type of heat-generating mat, the synthetic cloth and the leather can be easily contaminated from the excrement of the pet, so that it is not easy to manage, the waterproof function of the outer cover is low and water washing is difficult and the hardness and durability of the outer cover are low, It could damage the outer skin and cause its function to be lost, as well as electric shock to the pets.

In order to overcome these disadvantages, a heat-generating mat of the type in which the outer portion of the nichrome wire is wrapped with a synthetic resin to secure firmness and waterproofness has been released. However, in the case of a heat-generating mat for a pet having the nichrome wire heating module, The loss of function is easily occurred, and the contact between the nichrome wire and the enclosure is brought into line contact, so that the heat transfer efficiency is low.

In addition, there is a problem in that the temperature of the nichrome wire portion is very high due to the preheating of the nichrome wire, and the temperature of the other portion is low, causing uneven temperature throughout the heating mat.

In addition, after the wiring of the nichrome wire, a lot of steps are required until the process of forming the enclosure, thereby increasing the manufacturing cost.

In recent years, in order to overcome the disadvantages of such a nichrome wire heating module, a heating mattress for a pet having a surface heating element heating module as a heating element has been developed and sold.

The planar heating element refers to a flat heating element that generates heat on the surface rather than being generated by a line. Most typically, carbon is dispersed in a plane by using self resistance of carbon, A heating element is exemplified.

The surface heating element is widely used as residential heating for apartment, commercial, agricultural and various kinds of industrial heating because it is easy to control temperature, air is not polluted, hygienic and noiseless, and far infrared ray which is beneficial to human body is emitted.

In addition, when the planar heating element is used as a heat generating module, unlike a nichrome wire, a uniform heating characteristic can be realized, and unlike a nichrome wire, there is no fear of disconnection.

In the case of a heating mat for a pet using such an area heating element, an area heating element which is generally manufactured in the form of a film is cut to a predetermined size, an electric power is applied to the electrode portion, It is manufactured in the same way as the nichrome wire method, by using synthetic cloth, synthetic leather and natural leather, or by performing exterior finishing by forming an enclosure with a solid synthetic resin.

However, since the conventional heat-generating mat for a pet having a planar heating element is divided into a process for manufacturing an already-produced planar heating element and a process for manufacturing an outer casing and an outer casing, it is not economical However, there is a problem that the contact between the sheath and the enclosure and the surface heating element is insufficient, resulting in poor heat transfer efficiency.
