Heating system

Technical field

[0001] The present invention relates to a heating device.

Background art

[0002] In recent years, in a heating apparatus having a heating element, there has been a demand for heating that improves the heating effect of the heating element, shortens the heating time, and provides comfort and sensation.

[0003] Conventionally, as a general heating device, one having a structure in which a spiral-chromium wire is fixed in a groove on a surface of a ceramic sintered body formed in advance has been known.

[0004] In addition, a heating element in which a heating resistor wire, which is closely coiled and processed in a coil shape, is inserted in a quartz tube arranged in a casing having an open front surface, and heat generated from the heating element is reflected. There is also known a heating apparatus in which a reflector for radiating is arranged behind the heat generating element.

[0005] In addition, a heating apparatus employing the following glass heater is also known. The heating device is formed by etching two heat-resistant glass plates stacked on top of each other and iron foil laminated on a resin film to form a heater circuit, and sandwiched between the two heat-resistant glass plates. It has a structure in which the periphery of two heat-resistant glass plates stacked with the heat generating sheet sandwiched therebetween is hermetically bonded to each other (see, for example, Patent Document 1).

[0006] For example, Patent Document 2 is known as a prior art document disclosing a heating element having a structure similar to such a glass heater.

Disclosure of the invention

Problems to be solved by the invention

[0007] However, when the heating device having the above-described structure in which the -chrome wire is fixed is used, there are the following problems. When energized, the heat of the nichrome wire is conducted to the ceramic sintered body, so the rise characteristic of the heating rate is poor. Chrome wire may sag on the surface of the ceramic sintered body. For this reason, there is a risk of fire. Moreover, since the nichrome wire is exposed, the durability of the nichrome wire is low. This causes a problem that the quality of the heating device product is deteriorated.

[0008] In addition, in the case of a heating apparatus provided with a heating element in which a heating resistor wire, which is closely coiled and processed into a coil shape, is inserted in a quartz tube disposed in the casing having the front face opened, Or, there is no problem such as ignition, but since there is a space between the quartz tube and the heating resistor wire, there is a problem that the rising rate of the heating rate cannot be improved. In addition, since the radiant heat is also radiated from the front opening partial force, there is a problem that the heating range is narrow.

[0009] Further, when the heating elements disclosed in Patent Document 1 and Patent Document 2 are employed, the metal elements are disposed at a high temperature, so that the temperature distribution over the entire heating element is uniform. Is difficult. Also, it is difficult to make the degree of adhesion between the two pieces of glass and the metal element uniform. In addition, the thermal conductivity is partially different due to the presence of atmospheric air around the metal element. As a result, there is a problem that the heat dissipation efficiency of the heating device is lowered. In addition, since the uniformity of heat generation distribution is reduced, the metal element itself may be deformed. As a result, there is a problem that durability as a product is lowered.

The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a heating device having high thermal efficiency and high durability.

Means for solving the problem

[0011] In order to achieve the above object, the present invention provides a heating device having a heating unit and a control unit for controlling a heating temperature. The heating unit includes a transparent conductive film and a transparent conductive film. The heating device includes a heat generating glass having at least a pair of electrodes that are in contact with each other, and further includes a heat-resistant glass that surrounds part or all of the heat generating glass in the heating unit.

[0012] When the heating device having such a configuration is employed, since a heat generating glass having a transparent conductive film having high chemical stability and having at least a pair of electrodes in contact with the transparent conductive film is used as a heating element, Power can be supplied to the transparent conductive film and the heat generating glass can be heated efficiently. As a result, the entire surface of the heat generating glass can be heated uniformly, and the heating time can be increased. The climbing performance can be improved. Moreover, since the transparent conductive film itself is not deformed, the temperature distribution of the transparent conductive film can be made uniform. Therefore, the heating device can maintain high quality over a long period of time, and at the same time, the heat dissipation efficiency of the heating device can be increased. In addition, since the heat directly generated by the heat generation glass force is transmitted through the heat-resistant glass, the near infrared rays from the heat-resistant glass can immediately warm the user existing in front of the heating device. In addition, far-infrared radiation is emitted from the entire heat-resistant glass, so a heating environment with high thermal efficiency can be obtained.

[0013] Another aspect of the present invention is that in the previous invention, the top surface of the heating unit is opened, an air flow passage is formed between the heat generating glass and the heat resistant glass, and air is sent to the air flow passage. The heating system is equipped with an air inlet that sucks air in.

[0014] Since an opening is provided in the top surface of the heating unit, the air sucked into the air flow passage from the intake port receives the heat of the exothermic glass power arranged in the heating unit, and hot air is generated from the opening in the top surface. Discharged as. For this reason, the natural convection effect | action of air can be produced efficiently. As a result, the heating efficiency of the entire heating device is improved and the heating range can be made wider.

[0015] Further, according to another aspect of the present invention, in the previous invention, the heat-resistant glass is a heating device having a transparent conductive film on at least one side thereof. For this reason, the amount of near-infrared radiation radiated from the heat-resistant glass and its radiation range can be controlled by the heat directly radiated from the heat-generating glass passing through the heat-resistant glass.

[0016] Further, another aspect of the present invention is the heating apparatus further including a light emitting unit in the previous invention. For this reason, since light emission from the light emitting means can be visually recognized in a dark place, the energized state can be easily visually recognized and the user can be alerted. Further, by using the light emitting means, power consumption and heat generation can be reduced, and long-term use can be achieved.

[0017] Further, another aspect of the present invention is the heating apparatus further including deodorizing means in the previous invention. For this reason, by adopting a deodorizing means, the odor component in the air is absorbed and at the same time, the oxidative decomposition action is caused by the heat of the exothermic glass, and the odor component can be decomposed. As a result, the smell around the place of use can be reduced and more comfortable heating can be realized.

[0018] In another aspect of the present invention, in the previous invention, a plurality of pairs of electrodes are provided in the vertical direction of the heating unit, and the control unit is a heating device capable of applying a voltage to each pair of electrodes. For this reason, The calorific value of the exothermic glass can be adjusted. As a result, unnecessary heating can be eliminated and energy saving can be realized.

The invention's effect

[0019] According to the present invention, it is possible to provide a heating device with high thermal efficiency and high durability.

As shown in FIG. 1, the heating device 1 is mainly composed of a cylindrical columnar heating unit 10 and a main body 20 that is disposed in the lower part of the heating unit 10 and controls heat generation of the heating unit 10. One power switch button 31 and three button switches 32 are provided on the top surface of the main body 20 and next to the heating unit 10. The three button switches 32 have three temperature levels. It is a switch that allows adjustment. However, the number of button switches 32 and the locations of the power switch buttons 31 and the button switches 32 are not limited to the present embodiment. An air inlet 33 is provided on the side surface of the main body 20 and immediately below the heating unit 10. As will be described in detail later, the heating device 1 draws outside air from the intake port 33 and distributes the air to the heating unit 10.

As shown in FIG. 2, in the central region viewed from above the heating unit 10, a single heat generating glass 11 is disposed. In addition, two heat-resistant glasses 12 are arranged on the front and back surfaces of the heating unit 10 so as to surround both the front and back surfaces of the exothermic glass 11. A heat-resistant cover 14 having a substantially triangular prism shape is disposed on each of two side end surfaces (side surfaces perpendicular to the front and back surfaces) of the heat generating glass 11. The heat-resistant cover 14 is made of metal, and is made of heat-resistant resin. In addition, a portion surrounded by the heat generating glass 11, the heat resistant glass 12 and the heat resistant cover 14 is an air flow passage 13 that passes from the main body 20 to above the heating unit 10. By the air flow passage 13, the outside air sucked from the air inlet 33 can be discharged upward of the heating unit 10. The plane viewed from above the heating unit 10 may be a perfect circle, a rectangle, or a triangle in addition to the oval shape. Further, the number of the heat-generating glasses 11 is not limited to one, but can be two or more depending on the size and thermal efficiency requirements of the heating device 1.

[0026] Here, the configuration of the heat generating glass 11 will be briefly described.

As shown in FIG. 3, the exothermic glass 11 used in the heating device 1 has a transparent conductive film 16 on one surface of a glass (preferably glass with high heat resistance) 15, and the transparent conductive film 16 This glass has three pairs of electrodes 17 in the vertical direction on both the left and right sides of the surface. With such a structure, since the current can flow uniformly over the entire surface of the transparent conductive film 16, the heat generating glass 11 can efficiently generate heat. The number of electrodes 17 is not limited to the present embodiment. The exothermic glass 11 can be formed by vapor-depositing a solution containing tin oxide as a basic component and further adding several kinds of metallic substances on the glass 15, and attaching an electrode 17 to the vapor-deposited surface. The heat generating glass 11 is stable, transparent, and conductive. Further, the shape of the heat generating glass 11 is not limited to the rectangular shape, and the heat generating glass 11 having various shapes can be selected according to the purpose. In addition, by using glass 15 with a pattern or color etc., the heat generation is also rich in decoration. Glass 11 can be formed. Further, the transparent conductive film 16 may be disposed as a conductive layer not in the surface of the glass 15 but in the vicinity of the surface of the glass 15, and the electrode 17 may be provided so as to be in contact with the conductive layer.

As shown in FIG. 4, the heat-resistant glass 12 used in the heating device 1 has a transparent conductive film 16 on the surface thereof. The heat-resistant glass 12 can be formed by chemically depositing a solution containing tin oxide as a basic component and further adding several kinds of metallic substances on a glass (highly heat-resistant, preferably glass) 15. Stable heat-resistant glass 12 is obtained. Further, the shape of the heat-resistant glass 12 can be appropriately selected depending on the shapes of the heat generating glass 11 and the heating unit 10. However, the type of heat-resistant glass 12 manufactured by the above-described manufacturing method is merely an example, and other types of heat-resistant glass 12 may be adopted. For example, the transparent conductive film 16 may be disposed as a conductive layer not in the surface of the glass 15 but in the vicinity of the surface of the glass 15.

FIG. 5 is an enlarged plan view in which the upward force of the heating unit 10 is also enlarged so that the arrangement relationship between the heat-generating glass 11 and the heat-resistant glass 12 can be understood.

The heat-resistant glass 12 is a glass in which a transparent conductive film 16 is attached to the convex surface of the glass 15 as shown in FIG. 4 and FIG. That is, the transparent conductive film 16 is not attached to the concave surface of the heat generating glass 11 that faces the transparent conductive film 16. Heat from the transparent conductive film 16 of the heat generating glass 11 is released to the outside as far infrared rays (including near infrared rays) through the transparent conductive film 16 of the heat resistant glass 12. For this reason, the temperature of the heat-resistant glass 12 itself can be extremely lower than the temperature of the heat-generating glass 11, and the body of the user in front of the convex surface of the heat-resistant glass 12 can be effectively warmed. Can do.

[0031] However, the structure of the heat-resistant glass 12 may be reversed to the structure shown in FIG. That is, heat resistant glass with the transparent conductive film 16 attached to the concave surface of the glass 15 may be employed. Heat-resistant glass 12 (referred to as first heat-resistant glass) with transparent conductive film 16 on the concave side of glass 15 and heat-resistant glass having the structure shown in FIG. 5, that is, transparent conductive film 16 on the convex side of glass 15 When used in combination with a heat-resistant glass (referred to as the second heat-resistant glass), far infrared rays emitted from the transparent conductive film 16 of the first heat-resistant glass are directed to the second heat-resistant glass, Far infrared rays are emitted from the transparent conductive film 16 of the second heat-resistant glass to the outside. As a result, the second heat resistance The body of the user in front of the convex surface of the glass can be warmed more effectively.

FIG. 6 is a schematic configuration diagram of a control portion in main body 20 of heating device 1 according to the embodiment of the present invention.

[0033] As shown in FIG. 6, the heating device 1 includes a control unit 30 that controls various types of control, a memory 34 that stores various types of data, a power supply operation unit 35 that energizes the heating device 1, and a three-stage process. A temperature control unit 36 that adjusts the temperature so that the temperature is the same, a fan 37 that sucks in outside air, a temperature sensor 38 that detects the indoor temperature, a heat generation glass sensor 39 that detects the temperature of the heat generation glass 11, and a light emitting means And a deodorizing unit 41 which is a deodorizing means.

The power operation unit 35 and the temperature control unit 36 are operated by one power switch button 31 and three button switches 32 arranged on the top surface of the main body 20.

As shown in FIG. 1, the fan 37 is disposed below the side surface of the main body 20 and can be turned on and off by a CPU (not shown) that mainly constitutes the control unit 30. ! / When the fan 30 is driven, the sucked outside air passes through the air flow passage 13 of the heating unit 10 and is exhausted outside the opening partial force on the top surface of the heating unit 10.

[0036] The temperature sensor 38 is provided next to the air inlet 33 arranged on the side surface of the main body 20 shown in FIG. 1, and outputs indoor temperature data as a digital signal to a CPU (not shown). ing. However, the location and number of the temperature sensors 38 are not limited to the present embodiment.

The exothermic glass sensor 39 is attached to the back side of the exothermic glass 11, and outputs temperature data of the exothermic glass 11 to a CPU (not shown) as a digital signal. However, the arrangement location and the number of the exothermic glass sensors 39 are not limited to the present embodiment. For example, the exothermic glass sensor 39 may be provided on the back side above the heat generating glass 11 disposed in the heating unit 10.

[0038] The light emitting unit 40 includes a plurality of light emitting diodes (Light Emitting Diodes) of one color or two colors.

LED), and is arranged at a contact portion between the heating unit 10 and the main body 20 via the control unit 30. By providing the light emitting unit 40, it is possible to visually recognize the light emitted by the LED in the dark. For this reason, an energized state can be visually recognized easily and a user can be alerted. It also gives a sense of heating visually by emitting red or orange LEDs. it can. Further, the arrangement position of the light emitting unit 40 can be changed as appropriate according to the purpose. Furthermore, a human body sensor (not shown) may be employed so that the light emitting unit 40 emits light only when the user approaches the heating device 1.

The deodorizing unit 41 is arranged at a position close to the fan 37 of the main body 20. The inhaled outside air comes into contact with the deodorizing unit 41, thereby adsorbing and decomposing odorous components contained therein and deodorizing. The deodorized outside air passes through the air flow passage 13 and is exhausted to the outside through the opening on the top surface of the heating unit 10. As the structure of the deodorizing unit 41, a known structure can be used. Note that the deodorizing unit 41 may adopt a unit that does not adsorb and decompose odorous components but performs only adsorption.

[0040] Next, the operation of the heating device 1 having the above-described configuration will be described.

[0041] First, when the power switch button 31 is turned on, the transparent conductive film 16 of the heat generating glass 11 is energized through a lead wire (not shown) connected to the electrode 17 of the heat generating glass 11, and at the same time, Fan 37 is driven. As a result, the surface temperature of the heat generating glass 11 rises in a short time, and heat is radiated from the heat generating glass 11. The user of the heating device 1 can directly receive far infrared rays transmitted through the heat-resistant glass 12 installed in the heating unit 10 of the heating device 1, and from the heat-resistant glass 12 due to an increase in the surface temperature of the heat-resistant glass 12. Can receive far-infrared rays.

On the other hand, the outside air sucked by the rotation of the fan 37 passes through the main body 20 of the heating device 1 and reaches the air flow passage 13 of the heating unit 10. Therefore, the outside air contacts the heat-resistant glass 12, receives the heat, passes through the air flow passage 13, and is discharged outside through the opening on the top surface of the heating unit 10. Such an air flow promotes heat dissipation of the heat generating glass 11. Further, the exhausted hot air also carries the upward force of the heating device 1 to the surroundings of the room by the convection of the air, and makes the temperature distribution in the room uniform.

Next, when the three button switches 32 are pressed, the current value of the heat generating glass 11 is controlled by the three button switches 32, and the heat generation amount of the heat generating glass 11 can be controlled. Further, both the temperature sensor 38 and the heat generating glass sensor 39 are connected to the control unit 30, and the temperature can be adjusted to a preset temperature by switching the button switch 32. [0044] As described above, the power described for the embodiment of the heating device 1 according to the present invention. The heating device 1 according to the present invention is not limited to the above-described embodiment, and can be implemented in various modifications.

[0045] For example, the negative ion generator can be disposed in the heating device 1. For example, it is possible to provide a negative ion generating part in which a ceramic that generates negative ions is applied to a part of the surface of the heat generating glass 11 at an arbitrary position. In addition, a small negative ion generator may be installed in the main body 20 of the heating device 1. That is, any means capable of generating negative ions is not limited.

[0046] Further, for example, the deodorizing part 41 may be arranged in the form of a catalyst coating on both surfaces of the heat-resistant glass 12 without installing the deodorizing part 41 in the main body 20 of the heating device 1. With such a configuration, the odor of the room can be adsorbed by the catalyst coating applied to the surface of the heat-resistant glass plate 12, and is always activated by being heated by the exothermic glass 11, and always has a deodorizing function. Can be demonstrated. In addition, the room air taken in from the air inlet 33 via the fan 37 is adsorbed and decomposed by the odorous component by ascending the air flow passage 13 while contacting the catalyst coating on the back surface of the heat-resistant glass 12, Deodorized. In addition, the air outside the heat-resistant glass 12 is also heated to generate an updraft, and the airflow rises without contacting the catalyst coating on the surface of the heat-resistant glass 12, so that the odor component can be similarly deodorized. In addition, by the air convection effect of the updraft, the deodorizing effect can be further enhanced by increasing the temperature of the room and simultaneously increasing the air flow rate.

[0047] The present invention can be used in industries that manufacture or use heating devices.
