DETAILED DESCRIPTION

[0035] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the scheme of the embodiments of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the embodiments of the utility model, but the embodiments of the utility model can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the utility model, rather than all of the embodiments.

[0037] Reference Figures 1 to 6 As shown, this embodiment provides a bathroom heater, which includes a hollow box assembly 1.

[0038] The box assembly 1 has a blowing duct 10, and an air inlet 111 and an air outlet 112 are provided on the box assembly 1, and the air inlet 111 and the air outlet 112 are both connected to the blowing duct 10. A heating element for heating the air in the blowing duct 10 is provided in the blowing duct 10. Exemplarily, the heating element may include a heater, and the heater may be a PTC heater. Of course, the heater may also be a heating wire, etc.

[0039] The bathroom heater is usually installed on the ceiling of the bathroom through the box assembly 1. When taking a bath, the bathroom heater is turned on and the heating element starts to heat up to quickly heat the air in the bathroom, providing a warm environment for the user, helping the user to feel warmer and more comfortable when taking a bath. Figures 1 to 6 As shown, a lighting structure 9 can also be provided on the box assembly 1 to provide lighting for the user, making it convenient for the user to use the bathroom, and the lighting structure 9 can also help enhance the decorative effect of the bathroom.

[0040] For example, refer to Figure 6 As shown, the box assembly 1 is also provided with an air duct assembly 2, and a part of the blowing air duct 10 is formed in the air duct assembly 2, and the above-mentioned heating element can be arranged in the air duct assembly 2. At the same time, a blowing structure 4 can also be arranged in the blowing air duct 10, and the blowing structure 4 can include a blowing motor and a blowing wind wheel, and the output end of the blowing motor is connected to the rotating shaft of the blowing wind wheel to provide power to the blowing wind wheel, so that the air in the bathroom continuously enters the blowing air duct 10 from the air inlet 111 under the drive of the blowing wind wheel, and the air duct assembly 2 can guide the airflow formed in the blowing structure 4 to the air outlet 112, and the air in the blowing air duct 10 can be heated by the heating element when flowing through the air duct assembly 2, so as to form an airflow circulation and increase the temperature in the bathroom.

[0041] Reference Figures 1 to 6 As shown, a temperature prompting structure 3 is also provided on the outer side of the box assembly 1, and the temperature prompting structure 3 is configured to prompt the temperature in the installation space of the bathroom heater. Specifically, the installation space of the bathroom heater can be a bathroom.

[0042] Exemplarily, an electric control box 5 may be provided on the cabinet assembly 1, and the electric control box 5 may be electrically connected to the heating element to at least control the working state of the heating element.

[0043] Among them, the working state of the heating element may include starting heating, stopping heating, etc., and the heating state of the bathroom heater includes starting heating, stopping heating, etc. For example, when the user learns from the prompt result of the temperature prompt structure 3 that the temperature in the bathroom is low, the user can choose to turn on the bathroom heater and start heating by controlling the heating element, at which time the bathroom heater starts heating, or increase the working power of the heating element to increase the heating capacity of the bathroom heater, thereby heating the bathroom; for another example, when the user learns from the prompt result of the temperature prompt structure 3 that the temperature in the bathroom is high, the user can control the heating element to stop heating so that the bathroom heater stops heating, or reduce the power of the heating element to reduce the heating capacity of the bathroom heater, which can avoid the user from feeling uncomfortable due to overheating or overcooling to a certain extent, thereby providing the user with a comfortable bathroom environment.

[0044] For example, refer to Figures 1 to 6 As shown, a swing blade 6 can be provided at the air outlet 112, for example, the swing blade 6 is rotatably connected to the box assembly 1 to block at least the air outlet 112, or is staggered from the air outlet 112 to expose the air outlet 112 to allow hot air to flow out into the bathroom.

[0045] Reference Figure 6 As shown, in a specific implementation, the box assembly 1 also has an exhaust duct 7 isolated from part of the blowing duct 10, and the box assembly 1 is also provided with an exhaust port 123 connected to the exhaust duct 7, and the air inlet 111 is connected to the exhaust duct 7. An exhaust structure 8 is also provided in the box assembly 1, and the exhaust structure 8 may include an exhaust motor and an exhaust fan wheel located in the exhaust duct 7, and the output end of the exhaust motor is connected to the rotating shaft of the exhaust fan wheel to provide power to the exhaust fan wheel, so that the air in the bathroom is continuously driven by the exhaust fan wheel to enter the exhaust duct 7 from the air inlet 111 and is discharged to the outside of the bathroom through the exhaust port 123, so as to ventilate the bathroom.

[0046] Reference Figure 6 As shown, the blowing air duct 10 and the exhaust air duct 7 both include volute-shaped air duct sections, and the two volute-shaped air duct sections are respectively and correspondingly arranged on the outside of the blowing structure 4 and the exhaust structure 8.

[0047] Exemplarily, the electric control box 5 may also be electrically connected to the blowing structure 4 and the exhaust structure 8 respectively to control the working states of the blowing structure 4 and the exhaust structure 8 .

[0048] The bathroom heater provided in this embodiment is provided with a temperature prompting structure 3 on the outside of the box assembly 1, so that the temperature prompting structure 3 is configured to prompt the temperature in the installation space of the bathroom heater. In this way, the temperature conditions in the installation space such as the bathroom can be prompted in real time to a certain extent, so that the user can better grasp the current ambient temperature in the bathroom, and it is convenient for the user to flexibly adjust the working state of the heating element according to the actual use needs (such as bathing, washing, etc.) and the temperature conditions in the bathroom prompted by the temperature prompting structure 3, thereby adjusting the heating state of the bathroom heater, so that the temperature in the bathroom can meet the specific use needs of the user, thereby improving the convenience of using the bathroom heater to a certain extent, which is conducive to providing users with a comfortable bathroom temperature and improving the user's use experience. In addition, this can also save energy when the heating element is not turned on unnecessarily to a certain extent, and is beneficial to environmental protection. At the same time, compared with the solution that relies on the user to perceive the bathroom temperature to determine whether the heating function of the bathroom heater needs to be used, the bathroom heater provided in this embodiment can reduce the deviation of the perceived temperature of different users to a certain extent, especially for families with elderly people, children, etc., it can reduce the possibility of colds and other illnesses caused by temperature perception deviation to a certain extent, and the user experience is better.

[0049] In some embodiments, reference Figures 1 to 6 As shown, the temperature prompt structure 3 includes a temperature-sensitive color-changing component. The color of the temperature-sensitive color-changing component can change with the temperature in the bathroom heater installation space to display the temperature in the bathroom heater installation space.

[0050] In other words, different ambient temperatures in the bathroom can correspond to specific colors of the temperature-sensitive color-changing device. Therefore, in the physical state, the color presented by the temperature-sensitive color-changing device can prompt the user of the current ambient temperature of the bathroom. This setting not only makes it easy for users to grasp the ambient temperature in the bathroom at this time, but the prompt of the bathroom ambient temperature is also intuitive and easy to understand. Moreover, while realizing the prompt of the bathroom temperature, it does not require electricity, which achieves energy saving and environmental protection to a certain extent, and also adds a unique color and visual effect to the space in the bathroom.

[0051] For example, when the bathroom heater turns on the heating function, the hot air flowing out of the air outlet 112 gradually diffuses in the bathroom. As the temperature in the bathroom continues to rise, the heat of the air in the bathroom will be transferred to the cabinet assembly 1 again. The temperature-sensitive color-changing component on the cabinet assembly 1 will show a color corresponding to the temperature after being affected by the temperature.

[0052] The temperature-sensitive color-changing element can be made of a reversible thermosensitive material. Of course, the temperature-sensitive color-changing element can also be made of dye molecules with color changeability and temperature sensitivity.

[0053] Of course, in other implementations, the temperature prompt structure 3 can also be an electronic thermometer or the like.

[0054] In some embodiments, the temperature-sensitive color-changing component includes at least two temperature-sensitive color segments, and different temperature-sensitive color segments correspond to different displayed colors. The temperature in the bathroom heater installation space includes at least two temperature segments, and the temperature-sensitive color segments correspond to the temperature segments one by one, so that the temperature-sensitive color-changing component can be converted between at least two different colors according to the temperature in the bathroom heater installation space.

[0055] With this arrangement, the ambient temperature in the bathroom can be divided into at least two temperature intervals, and there is a one-to-one correspondence between the temperature intervals and the temperature-sensitive color segments. In this way, the ambient temperature in the bathroom is displayed by at least two different colors, which further improves the convenience for users to obtain the ambient temperature of the bathroom, and the prompt effect is more intuitive.

[0056] Of course, the temperature-sensitive color-changing element may also include a temperature-sensitive color segment, and when the temperature in the bathroom is within the temperature segment corresponding to the temperature-sensitive color segment, the temperature-sensitive color-changing element presents a color, and when the temperature in the bathroom is not within the temperature segment corresponding to the temperature-sensitive color segment, the temperature-sensitive color-changing element is colorless. That is, the temperature-sensitive color-changing element switches between color and colorless.

[0057] In some embodiments, the temperature-sensitive color-changing component includes three temperature-sensitive color segments. When the temperature in the bathroom heater installation space is less than the first preset temperature threshold, the temperature-sensitive color-changing component presents a first color; when the temperature in the bathroom heater installation space is greater than or equal to the first preset temperature threshold and less than or equal to the second preset temperature threshold, the temperature-sensitive color-changing component presents a second color; when the temperature in the bathroom heater installation space is greater than the second preset temperature threshold, the temperature-sensitive color-changing component presents a third color. Wherein, the second preset temperature threshold is greater than the first preset temperature threshold, and the first color, the second color, and the third color are all different.

[0058] With this setting, the ambient temperature in the bathroom can be divided into three temperature ranges through the different colors of the temperature-sensitive color-changing component for prompting. In this way, the user can know the ambient temperature in the bathroom more intuitively and accurately, making the temperature-sensitive color-changing component more intuitive and convenient to use. Moreover, when the bathroom heater turns on the heating function, the user can intuitively see that the temperature in the bathroom is gradually rising as the heating element starts to heat up.

[0059] Exemplarily, the first preset temperature threshold may be 16°C, and the first color may be blue, that is, when the temperature in the bathroom is low, the temperature-sensitive color-changing component displays blue; the second temperature threshold may be 24°C, and the second color may be green, that is, when the temperature in the bathroom is in a comfortable temperature range (16°C-24°C), the temperature-sensitive color-changing component displays green; when the temperature in the bathroom is greater than 24°C, the temperature-sensitive color-changing component displays red, indicating that it is suitable for bathing.

[0060] For example, when the temperature is lower than 16°C, the user can turn on the heating function of the bathroom heater. The hot air is blown out from the air outlet 112 and reaches the space in the bathroom. As the hot air gradually spreads to the entire bathroom and the temperature in the bathroom rises, the temperature-sensitive color-changing component will gradually change color, for example, from blue to green and then to red. The whole process allows the user to more intuitively see that the temperature in the bathroom is rising.

[0061] Of course, in other implementations, the second color may also be yellow-green, and the third color may also be red. The specific colors may be customized according to actual needs.

[0062] In some embodiments, the temperature prompt structure 3 further includes a base body. The temperature-sensitive color-changing element is arranged on the base body, and the base body is connected to the box assembly 1 .

[0063] This arrangement facilitates the connection and fixation of the temperature-sensitive color-changing component through the base, making the temperature prompt structure 3 on the box assembly 1 more stable and reliable, and ensuring the good temperature prompt effect of the temperature prompt structure 3.

[0064] In some embodiments, the temperature-sensitive color-changing element includes temperature-sensitive color powder, and the base is light-transmissive. The base and the temperature-sensitive color powder are mixed and then integrally formed into the temperature prompt structure 3 by injection molding.

[0065] With this arrangement, the overall structural strength of the temperature-sensitive color-changing component and the substrate is high, which is beneficial to ensuring the stability of the temperature-sensitive color powder and the display effect of temperature, and is convenient for subsequent assembly.

[0066] In a specific implementation, before the substrate and the temperature-sensitive color powder are injection-molded, the substrate and the temperature-sensitive color powder can be evenly mixed, which can achieve a better display effect on the temperature.

[0067] For example, the substrate may be plastic, or may be acrylic, etc.

[0068] In some embodiments, the temperature prompting structure 3 is adhesively connected to the box assembly 1. In this way, the connection between the temperature prompting structure 3 and the box 12 is simple, convenient, and highly reliable.

[0069] In some embodiments, the temperature prompt structure 3 is detachably connected to the box assembly 1. With this arrangement, when one of the temperature prompt structure 3 and the box assembly 1 is damaged, only the damaged component needs to be replaced, thereby reducing the maintenance and use costs to a certain extent.

[0070] Exemplarily, the temperature prompt structure 3 and the box assembly 1 can be detachably connected by means of screws, buckles, etc.

[0071] In some embodiments, when the temperature-sensitive color-changing component includes temperature-sensitive color powder, the base is a spray coating. The spray coating is mixed with the temperature-sensitive color powder and then sprayed on the box assembly 1 by spraying to form a temperature prompting structure 3 on the outside of the box assembly 1. In this case, the temperature prompting structure 3 is a temperature-sensitive color-changing coating.

[0072] With this arrangement, the arrangement of the temperature-sensitive color-changing element on the box assembly 1 is simple and convenient, and the temperature-sensitive color powder on the box assembly 1 has high reliability and long service life.

[0073] The spray coating may be a primer, and of course, the spray coating may also be ink or the like.

[0074] In some embodiments, reference Figures 1 to 6 As shown, the box assembly 1 has a cavity 113 that is recessed toward the inner cavity of the box assembly 1 , and the temperature prompting structure 3 is located in the cavity 113 .

[0075] With such arrangement, the position of the temperature prompting structure 3 can be prompted and positioned to a certain extent through the concave cavity 113, thereby improving the convenience and reliability of the temperature prompting structure 3 during installation to a certain extent.

[0076] Exemplarily, when the temperature prompt structure 3 is not formed by spraying, a positioning groove can be opened on the cavity wall of the cavity 113, with the notch of the positioning groove facing the temperature prompt structure 3, and a positioning protrusion that can extend into the positioning groove is provided on the temperature prompt structure 3, so as to achieve positioning of the temperature prompt structure 3 and further improve the assembly efficiency and the stability of the temperature prompt structure 3.

[0077] When implementing it, refer to Figures 1 to 6 As shown, the box assembly 1 may include a panel 11 and a hollow box 12. The panel 11 is connected to the box 12, and the air inlet 111 and the air outlet 112 are both arranged on the panel 11. The air duct 10 is located in the box 12, and the concave cavity 113 is specifically arranged on the panel 11.

[0078] For example, refer to Figure 6 As shown, the box body 12 may include a box body 121 and a box cover body 122. The box body 121 is a hollow structure with an opening on one side. The box cover body 122 is covered at the opening of the box body 121. The panel 11 may be connected to the box body 121 through a keel or the like, and at least part of the panel 11 is located on the side of the box cover body 122 facing away from the box body 121.

[0079] In specific implementation, the exhaust port 123 is specifically opened on the box body 121, and the air duct assembly 2, the blowing structure 4 and the exhaust structure 8 are all arranged in the box body 121, and the box cover body 122 is provided with a first pair of interfaces at the position corresponding to the blowing structure 4, which can be connected with both the blowing duct 10 and the blowing wheel, and the box cover body 122 is provided with a second pair of interfaces at the position corresponding to the exhaust structure 8, which can be connected with both the exhaust duct 7 and the exhaust wheel.

[0080] In some embodiments, reference Figures 1 to 3 As shown, the side surface of the temperature prompt structure 3 facing away from the box assembly 1 does not protrude from the cavity 113 .

[0081] Such an arrangement can, to a certain extent, prevent the temperature prompt structure 3 from interfering with the external structure and being damaged, thereby protecting the temperature prompt structure 3 to a certain extent and being beneficial to improving the stability of the temperature prompt structure 3 .

[0082] In some embodiments, reference Figure 1 and Figure 3 As shown, the cavity 113 is extended along the length direction of the box assembly 1, and along the extension direction of the cavity 113, the size of the temperature prompt structure 3 is adapted to the size of the cavity 113. Figure 1 and Figure 3 XX direction shown.

[0083] Such an arrangement can increase the size and area of ​​the temperature prompt structure 3 on the horizontal plane of the box assembly 1 to a certain extent, thereby facilitating improving the prompt effect of the temperature in the bathroom.

[0084] Of course, in other implementations, the temperature prompt structure 3 may also include a temperature sensor and a voice announcer electrically connected to the temperature sensor, wherein the temperature sensor is used to detect the temperature in the bathroom, and the voice announcer is used to voice announce the temperature detection result of the temperature sensor.
