[0037] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments. Specific embodiments

[0038] Ceiling heater embodiment

[0039] Combined with Figures 3 to 5 , the ceiling heater 100 includes a panel unit 101 and a main unit 102. In this embodiment, the panel unit 101 and the main unit 102 are of a split structure. During installation, first install the main unit 102 on the ceiling or the keel of the ceiling, and then connect the panel unit 101 with the keel to install the panel unit 101 on the keel, so that the panel unit 101 is aligned with the main unit 102 and is arranged to match the main unit 102. Of course, in other embodiments, the panel unit 101 can also be assembled with the main unit 102 into an integral structure, that is, during installation, first install the main unit 102 on the ceiling or the keel of the ceiling, and then install the panel unit 101 on the main unit 102.

[0040] The panel unit 101 includes a face cover 1, a lighting module 2, and a wire pressing block 3. In combination Figure 6 , the face cover 1 preferably has a decorative face 11 and a connection frame portion 12; wherein, a light outlet 111 and a first air outlet 112 are provided on the decorative face 11, and both the light outlet 111 and the first air outlet 112 penetrate through the decorative face 11 in the height direction of the panel unit 101. The connection frame portion 12 is disposed around the circumference of the decorative face 11, and the connection frame portion 12 is connected to the decorative face 11; preferably, the connection frame portion 12 and the decorative face 11 are integrally formed. In addition, a first air inlet 113 is formed between the connection frame portion 12 and the decorative face 11.

[0041] In order to cooperate with the design that the panel unit 101 and the host unit 102 in this embodiment are of a split structure and the panel unit 101 is installed on the keel of the ceiling, the connection frame portion 12 preferably has an assembly plate 121, the assembly plate 121 is parallel to the height direction of the panel unit 101, and a buckle structure 1211 is formed on the assembly plate 121. When the panel unit 101 is assembled with the keel, the buckle structure 1211 on the face cover 1 can be used to engage with the keel, and then the panel unit 101 is installed on the keel. It can be seen that through the structural design of the face cover 1, the assembly of the face cover 1 is made more convenient and fast. At the same time, since the face cover 1 is not directly connected to the housing 4 of the host unit 102 of the bathroom heater 100, the structures of the face cover 1 and the housing 4 of the host unit 102 are also simplified, reducing the production cost and the installation difficulty of the bathroom heater 100.

[0042] The lighting module 2 is disposed inside the face cover 1, that is, when the bathroom heater 100 is installed, most of the lighting module 2 is located on the side of the face cover 1 close to the host unit 102. The lighting module 2 includes a light-transmitting lamp frame 21, a lamp body 22, a light-transmitting plate 23, a Rayleigh scattering plate 24, a light-emitting layer, a first lamp group 26, a second lamp group 27, and a control module 28.

[0043] In combination Figure 7 and Figure 8 , in this embodiment, the light-transmitting lamp frame 21 preferably has an inclined portion 211, a mating portion 212, and a protruding portion 213. The inclined portion 211 is inclined with respect to the height direction of the panel unit 101, and in the height direction of the panel unit 101, the opening of the inclined portion 211 close to the top of the panel unit 101 is smaller than the opening of the inclined portion 211 close to the bottom of the panel unit 101. The second end of the inclined portion 211 is connected to the mating portion 212, and the inclined portion 211 and the mating portion 212 are bent, and the protruding portion 213 is located at the junction of the inclined portion 211 and the mating portion 212.

[0044] When the transparent light frame 21 is assembled with the lamp body 22 and the face cover 1, the transparent light frame 21 is located at the light outlet 111, and the lamp body 22 covers the transparent light frame 21; wherein, the fitting portion 212 is located inside the decorative surface portion 11 of the face cover 1 and is adjacent to the decorative surface portion 11, and the fitting portion 212 is located at the open end of the lamp body 22; and the protruding portion 213 is located inside the light outlet 111 of the decorative surface portion 11 and is connected with the light outlet 111 in a matching manner. It can be seen that the protruding portion 213 can serve as a quick positioning device for the assembly of the lighting module 2 and the face cover 1 during assembly; therefore, through the design of the transparent light frame 21, both the lighting effect of the bathroom heater 100 can be ensured, and the assembly between the transparent light frame 21, the face cover 1 and the lamp body 22 can be made simpler and more convenient.

[0045] In addition, after the transparent light frame 21 is assembled with the lamp body 22, a first lamp cavity 221 and a second lamp cavity 222 are formed between the lamp body 22 and the transparent light frame 21; wherein, the first lamp cavity 221 faces the light outlet 111, and the second lamp cavity 222 is arranged around the first lamp cavity 221 and is located between the light outlet 111 and the first lamp cavity 221. The light-transmitting plate 23, the Rayleigh heat dissipation plate 24, the reflective layer 25 and the first lamp group 26 are all arranged in the first lamp cavity 221. The first lamp group 26 is arranged around the circumference of the Rayleigh heat dissipation plate 24. The light-transmitting plate 23, the Rayleigh heat dissipation plate 24 and the reflective layer 25 are stacked in sequence from the transparent light frame 21 to the lamp body 22, and the light-transmitting plate 23 is adjacent to the first end of the inclined portion 211 of the transparent light frame 21. This design enables the light emitted by the first lamp group 26 to simulate the natural light illumination effect with the assistance of the light-transmitting plate 23, the Rayleigh heat dissipation plate 24 and the reflective layer 25.

[0046] The first lamp group 26 is electrically connected to the control module 28, so that the control module 28 can control the first lamp group 26 to illuminate according to a preset lighting mode. Preferably, the control module 28 can control the first lamp group 26 to emit at least one of white light or warm white light. Among them, the color temperature of the white light is between 4000K (Kelvin) and 6500K, so that the light emitted by the first lamp group 26 can cooperate with the light-transmitting plate 23, the Rayleigh heat dissipation plate 24 and the reflective layer 25 to achieve traditional conventional lighting; the color temperature of the warm white light is between 1800K and 3200K, and the light emitted by the first lamp group 26 can cooperate with the light-transmitting plate 23, the Rayleigh heat dissipation plate 24 and the reflective layer 25 to create the lighting effect of dusk sunset or sunrise.

[0047] In this embodiment, the light outlet 111 is rectangular, and correspondingly, the transparent light frame 21 is a rectangular frame; the first lamp group 26 includes two first lamp strips 261. The two first lamp strips 261 are distributed along the width direction of the panel unit 101, and the first lamp strip 261 extends along the length direction of the light outlet 111; through the design and layout of the first lamp group 26, the lighting effect of the first lamp group 26 can be ensured.

[0048] The second lamp group 27 is circumferentially arranged in the second lamp cavity 222 around the second lamp cavity 222, and the LED lamp beads 271 of the second lamp group 27 are arranged towards the inclined portion 211 of the light-transmitting lamp frame 21. The second lamp group 27 is electrically connected to the control module 28, so that the control module 28 can control the second lamp group 27 to illuminate according to a preset lighting mode. Preferably, the control module 28 can control the second lamp group 27 to emit at least one of near-infrared light, red light, yellow light, green light, blue light, and purple light, so that the second lamp group 27 can achieve certain beauty, phototherapy and other effects, and the second lamp group 27 can also have the function of an atmosphere lamp, thereby improving the lighting effect and lighting function of the bathroom heater 100. While enhancing the practicality of the bathroom heater 100, it can also further increase the aesthetics and personalized design of the bathroom heater 100. Among them:

[0049] The wavelength of the near-infrared light preferably ranges from 700 nanometers to 850 nanometers, and the wavelength of the red light preferably ranges from 650 nanometers to 700 nanometers, so that the light emitted by the second lamp group 27 can penetrate into the deep layer of the human skin surface, stimulate the production of collagen, thereby helping to reduce fine lines and wrinkles, promote skin regeneration and repair, and increase skin elasticity.

[0050] The wavelength of the yellow light preferably ranges from 570 nanometers to 590 nanometers, so that the light emitted by the second lamp group 27 can improve the problems of skin spots and pigmentation in the human body, reduce the production of melanin, and make the skin color more uniform.

[0051] The wavelength of the green light preferably ranges from 520 nanometers to 550 nanometers, so that the light emitted by the second lamp group 27 can soothe and calm the skin, and reduce the problems of telangiectasia and sensitivity.

[0052] The wavelength of the blue light preferably ranges from 405 nanometers to 420 nanometers, so that the light emitted by the second lamp group 27 can kill bacteria under the epidermis, and has a certain effect on treating acne and other skin inflammations; in addition, the blue light can also balance the oil secretion of the skin and shrink pores.

[0053] The wavelength of the purple light preferably ranges from 380 nanometers to 420 nanometers, so that the light emitted by the second lamp group 27 can be used for antibacterial and sterilization, and has a certain effect on treating acne and other skin infections.

[0054] It can be seen that through the design of various light wavelengths, the light emitted by the second lamp group 27 can achieve better beauty, phototherapy and other effects, thereby improving the user experience and comfort.

[0055] Furthermore, in combination with Figure 9In this embodiment, the second light group 27 is a rectangular light strip, which matches the second light cavity 222, and the lighting effect of the second light group 27 can be guaranteed by designing and arranging the second light group 27. Of course, as another optional solution, in other embodiments, the second light group 27 may also include a plurality of second light strips, and the number of the second light strips is preferably the same as the number of sides of the light-transmitting light frame 21, and the plurality of second light strips correspond to the plurality of sides of the light-transmitting light frame 21 one by one, so that a second light strip is provided in one side of the second light cavity 222.

[0056] like Figure 10 As shown, the LED lamp beads 271 of the second lamp group 27 are all-in-one LED lamp beads. Among them, when the control module 28 controls the second lamp group 27 to switch the light wavelength, it can switch the gear (for example, directly jump from one color light to another color light); or perform gradual switching (for example, gradually switch from the current color light to another color light according to the wavelength change), and when the gradual switching is performed, all the LED lamp beads 271 of the second lamp group 27 can be switched at the same time, or according to a preset direction (such as from left to right, from top to bottom, clockwise or counterclockwise, etc.), the LED lamp beads 271 of the second lamp group 27 can be switched in a gradual marquee-style light color.

[0057] In addition, in this embodiment, the light module 2 can only be in the beauty mode for lighting, such as only the second light group 27 is used for lighting, and the second light group 27 is used for lighting in a certain light color, or the second light group 27 is used for lighting by switching between different light colors; or the light module 2 can only be in the simulated natural light lighting mode, such as only the first light group 26 is used for lighting (such as the first light group 26 is used to emit warm white light); or the light module 2 can only be in the traditional lighting mode, such as the first light group 26 is used for lighting with white light. Of course, the first light group 26 and the second light group 27 can also be used for lighting at the same time.

[0058] In addition, the lamp body 22 is preferably made of ABS (acrylonitrile-butadiene-styrene copolymer) material, PVC (polyvinyl chloride plastic) material, PP (polypropylene) material, PBT (polybutylene terephthalate) material or PC (polycarbonate) material. The lamp body 22 is made of the above-mentioned high thermal conductivity material, so that the first lamp group 26 and the second lamp group 27 can be reliably cooled, so that the first lamp group 26 and the second lamp group 27 can work stably and ensure the service life of the first lamp group 26 and the second lamp group 27; wherein the first lamp group 26 and the second lamp group 27 can be fixed to the lamp body 22 by bonding.
