Description

Technical Field

[0001] The utility model relates to the technical field of door leaves, in particular to a heating door handle, a push-pull shower door and a side-hung shower door. Background Art

[0002] The door handle is an indispensable door accessory that has both decorative and functional properties. Door handles are made of various materials such as ceramic, solid wood, metal, glass, crystal, plastic, alloy, etc. Currently, the materials of shower door handles on the market are basically metal materials such as stainless steel or copper. When in a relatively cold environment, the surface temperature of the metal door handle is relatively low, and it will feel extremely cold when pushing or pulling the door handle with the hand, resulting in a very poor user experience. Moreover, people usually bring clothes and towels into the bathroom before taking a shower. In winter, the indoor temperature is relatively low, and after taking a shower, the bathroom is filled with water vapor. Under the influence of water vapor, the clothes or towels will become wet and feel even colder. Therefore, there is an urgent need for a door handle that can generate heat and heat clothes. Summary of the Utility Model

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a heating door handle, a push-pull shower door and a side-hung shower door, which can enable people to put on warm clothes after taking a shower in winter and avoid touching the cold shower door handle before and after taking a shower.

[0004] In a first aspect of the utility model, a heating door handle is provided, which includes an inner handle and an outer handle. One end of the inner handle and the outer handle penetrates through the door leaf and is connected, and the other ends are respectively fixed on the inner and outer sides of the door leaf; the inner handle and the outer handle are hollow inside and filled with heating elements; the outer handle includes an armrest heating part and a clothes heating part for heating clothes; the heating element is electrically connected to a power source.

[0005] The heating door handle according to the embodiment of the utility model has at least the following beneficial effects: Most bathroom door handles are made of metal materials. However, metal is a good thermal conductor that can quickly transfer the heat on the hand, causing the hand temperature to drop faster and making people feel cold. In addition, clothes also feel cold when worn in winter. For this reason, heating elements are filled in the door handle and connected to a power source. The power switch is used to control the heating elements to generate heat, so as to increase the temperature of the door handle and make people feel more comfortable when touching the door handle. At the same time, by setting the clothes heating part, clothes can be hung on the clothes heating part before taking a shower. After taking a shower, the clothes have been heated for a period of time, and wearing the heated clothes will feel warmer and more comfortable. Usually, a wet towel can be hung on the clothes heating part, and the clothes heating part can dry it to reduce the growth of bacteria on the towel.

[0006] As a preferred solution, the clothing heating part is rotatably connected to the armrest heating part and rotates around the armrest heating part as the axis.

[0007] As a preferred solution, the clothing heating part is provided with a connection structure; both the connection structure and the armrest heating part are circular tubes with the same diameter, and the connection structure is coaxially assembled on the armrest heating part and can rotate around the axis. Since the outer handle is assembled on the outer surface of the door leaf, and the clothing heating part needs to realize the function of rotating around the axis of the outer handle, if the diameter of the connection structure is too large, it will affect the rotation angle of the clothing heating part. Therefore, the connection structure is set as a circular tube structure with the same diameter as the outer handle, which is not only beautiful but also reduces the volume of the outer handle.

[0008] As a preferred solution, the clothing heating part is further provided with a heating plate extending outward from the connection structure; when the heating plate rotates to be perpendicular to the ground, the power supply is connected and heating starts; when the heating plate rotates to be parallel to the ground, the power supply is disconnected and heating stops.

[0009] The rotatable clothing heating part can realize the switching between two states by rotation: In the first state, when the heating plate is perpendicular to the ground, the clothing heating part is connected to the power supply and starts heating. The vertical heating plate can increase the heating area of clothes, towels, etc., improve the utilization efficiency of heat, and quickly heat the clothes and towels. In the second state, the heating plate is in a horizontal position. At this time, the clothing heating part is disconnected from the power supply and stops heating. The horizontally placed heating plate can also serve as a temporary storage platform. In this way, it is convenient for users to control the switch of the clothing heating part according to actual needs. When the clothing heating part is not needed, its heating function can be turned off to save electricity.

[0010] As a preferred solution, it further includes a temperature sensor and a controller; the controller is electrically connected to the power supply; the temperature sensor is signal-connected to the controller; the controller controls the output power of the power supply according to the signal fed back by the temperature sensor. The temperature sensor is used to detect the temperature to keep the inner handle and the outer handle at a constant temperature and heat. The controller adjusts the temperature of the heating element and the clothing heating part in real time according to the temperature fed back by the temperature sensor.

[0011] As a preferred solution, an outlet for wire routing is provided at the connection end of the inner handle and the outer handle. Since both the inner handle and the outer handle are hollow structures, the heating element is filled inside the inner handle and the outer handle and transfers heat to the inner handle and the outer handle to increase the temperature of their surfaces.

[0012] As a preferred solution, the heating element is a carbon fiber heating body. Under the action of an electric field, the microcrystals in the carbon fiber heating body cause a large number of carbon crystal molecular groups to perform Brownian motion. The carbon molecules rub and collide with each other, generating a large amount of heat energy, thereby realizing the conversion of electrical energy into heat energy. A temperature difference is formed between the surface of the carbon crystal plate and the object or air in close contact with the carbon crystal plate. According to the law of heat transfer, the direction of heat transfer is always from the high-temperature body to the low-temperature body. Therefore, the heat generated by the carbon fiber heating body will be transferred to the surrounding objects or air, thereby increasing the temperature of the inner handle and the outer handle. The carbon fiber heating body, as a heating element, has the advantages of fast heating, high electro-thermal conversion efficiency, high temperature resistance, oxidation resistance, and long service life. It effectively solves the problems of easy oxidation, low strength, and short service life of electric heating materials such as metal wires and silicon carbide.

[0013] The second aspect of the present invention provides a push-pull shower door, including the heating door handle in any of the above technical solutions. The advantages of the heating door handle in the above technical solutions will not be elaborated here.

[0014] As one of the preferred solutions, it further includes a track provided with a drag chain; one end of the drag chain is electrically connected to the power supply, and the other end is electrically connected to the heating element and the clothing heating part respectively. The drag chain has both a protective function and a guiding function, and has the characteristics of strong flexibility and high wear resistance. The drag chain can effectively protect the cable, neatly guide the cable to the designated position, and avoid crossing and entanglement; the drag chain has a large bending radius and a flexible movement mode, and can adapt to various complex movement trajectories and space limitations. The drag chain is made of high-strength and wear-resistant materials, and can withstand long-term friction and wear to extend the service life of the cable.

[0015] The third aspect of the present invention provides a hinged shower door, including the heating door handle in any of the above technical solutions. The advantages of the heating door handle in the above technical solutions will not be elaborated here.

[0016] Other features and advantages of the present invention will be described in the subsequent specification, and some will become obvious from the specification or be understood by implementing the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will describe in detail the embodiments of the present utility model. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0026] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as up and down is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0027] In the description of the present utility model, the meaning of "a plurality" is more than two. Understandings such as greater than, less than, and exceeding do not include the present number, and understandings such as above, below, and within include the present number. If there is a description of first and second, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0028] In the description of the present utility model, it should be noted that terms such as setting, installation, and connection should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0029] The following will clearly and completely describe the technical solution of the present utility model with reference to the drawings. Obviously, the following described embodiments are some embodiments of the present utility model, not all embodiments.

[0030] The environment in the bathroom is humid, and the doorknob is prone to getting wet. Therefore, most of the doorknobs of shower doors on the market are made of stainless steel metal materials. Using metal materials can increase the service life of the doorknob. However, due to the good thermal conductivity of metal, when touching the doorknob with the hand, the doorknob will quickly absorb the heat of the hand, causing the temperature of the hand to drop rapidly. Therefore, touching a metal doorknob in cold winter will feel particularly cold, which greatly affects the experience.

[0031] However, in winter, in addition to the cold feeling of the doorknob affecting the user experience, cold clothes will also affect the user experience. For this reason, the present utility model provides a heat-generating doorknob that can both generate heat and heat and dry clothes, and can heat the clothes that the user needs to wear after taking a shower.

[0032] This embodiment provides a heat-generating doorknob, as Figure 1 、 Figure 2 shown, including an inner doorknob 1 and an outer doorknob. Both the inner doorknob 1 and the outer doorknob have two ends. Specifically, one end of the inner doorknob 1 is detachably connected to one end of the outer doorknob, such as threaded connection or snap connection, etc. In this embodiment, threaded connection is selected for illustration; and the other ends of the inner doorknob 1 and the outer doorknob are respectively connected to the inner and outer sides of the door leaf 51. Specifically, the end of the inner doorknob 1 connected to the outer doorknob passes through the door leaf 51 for connection, and the other ends of the inner doorknob 1 and the outer doorknob are respectively fixed to the door leaf 51 using mounting bolts. It can be understood that the inner doorknob 1 can be a horizontal doorknob or a vertical doorknob fixed to the inner surface of the door leaf.

[0033] Both the inner doorknob 1 and the outer doorknob are of hollow structure. A carbon fiber heating element is selected as the heating element, and the carbon fiber heating element is filled into the central control area of the inner doorknob 1 and the outer doorknob. The power supply is electrically connected to the carbon fiber heating element. When the carbon fiber heating element is connected to the power supply to form a closed-loop circuit, it starts to generate heat. Under the action of an electric field, the microcrystals in the carbon fiber heating element cause a large number of carbon crystal molecular clusters to perform Brownian motion. The carbon molecules rub and collide with each other, generating a large amount of heat energy. The heat energy is transferred to the surfaces of the inner doorknob 1 and the outer doorknob, and when touching the inner doorknob 1 or the outer doorknob with the hand, it will not feel cold. Specifically, the outer doorknob includes an armrest heating part 2 and a clothing heating part 3, and the armrest heating part 2 and the clothing heating part 3 are both filled with carbon fiber heating elements.

[0034] It can be understood that for the inner handle 1 and the outer handle of the present utility model, taking the bathroom as a reference, the side of the door leaf 51 inside the bathroom is the side where the inner handle 1 is installed, and the side outside the bathroom is the side where the outer handle is installed. When people take a bath, they usually hang the clothes to be worn after taking a bath outside the bathroom to avoid getting the clothes wet. Therefore, in this embodiment, the clothing heating part 3 is arranged on the outer handle. It can be understood that since clothes need to be hung on the outer handle, the outer handle should be a horizontal handle. Hanging clothes and towels on the clothing heating part 3 and turning on the power can heat and dry the clothes and towels. Specifically, the carbon fiber heating element in the clothing heating part 3 is connected to the power supply and the controller, and the controller can be used to control the heating temperature of the clothing heating part 3.

[0035] In order to obtain a better control experience and make the switch of the clothing heating part 3 more convenient, in this embodiment, the clothing heating part 3 is rotatably connected to the armrest heating part 2 and can rotate around the axis of the armrest heating part 2. Specifically, the clothing heating part 3 is provided with a connection structure 301 for cooperating with the armrest heating part 2 and a heating plate 302 for increasing the clothing heating area. Both the connection structure 301 and the armrest heating part 2 are circular tubular structures, and the diameter of the connection structure 301 is equal to the diameter of the armrest heating part 2; the connection structure 301 extends outwards with a plate-shaped heating plate 302, and the heating plate 302 is rectangular and filled with a carbon fiber heating element for heating inside. As Figure 3 、 Figure 4 shown, the heating plate 302 can be rotated around the axis of the armrest heating part 2 through the above connection method. More specifically, the overall shape of the outer handle is C-shaped, and the height of the middle convex part is greater than the height of the heating plate 302, so that the heating plate 302 can rotate 360° around the armrest heating part 2.

[0036] More specifically, the rotation of the clothing heating part 3 around the armrest heating part 2 is equivalent to a rotary switch. Usually, multiple contacts are contained inside the rotary switch. When the rotary switch rotates, the contacts rotate and connect or disconnect the connection with other circuits. When the contacts are connected, the current can flow; when the contacts are disconnected, the current in the circuit is blocked. Similarly, multiple contacts are arranged at the connection between the connection structure 301 and the armrest heating part 2 to control the heating switch of the clothing heating part 3, so as to achieve: when the heating plate 302 rotates to be parallel to the ground, as Figure 3 shown, the heating plate 302 stops heating; when the heating plate 302 rotates to a state perpendicular to the ground and the heating plate 302 is below the axis of the armrest heating part 2, as Figure 4 shown, the heating plate 302 starts heating. It can be understood that the connection structure 301 is also filled with a carbon fiber heating element inside. Therefore, the part of the clothing in contact with the connection structure 301 can also be heated.

[0037] In order to keep the temperature of the heated door handle constant, in this embodiment, a temperature sensor is added inside the outer door handle to monitor the temperature in real time. The heated door handle makes corresponding adjustments according to the temperature change to achieve the constant temperature of the inner door handle 1 and the outer door handle. The heating power is increased or decreased according to the temperature feedback by the temperature sensor to keep the inner door handle 1 and the outer door handle heated at a constant temperature.

[0038] It can be understood that a temperature sensor refers to a sensor that can sense temperature and convert it into an available output signal, including two categories: contact type and non-contact type. Since it is necessary to measure the temperatures of the inner door handle 1 and the outer door handle, a contact type temperature sensor needs to be selected for temperature measurement. The selection of a specific temperature sensor can be determined by comprehensively evaluating aspects such as temperature range, accuracy, and stability according to the specific application scenario and measurement requirements.

[0039] As Figure 7 shown, an outlet 4 is provided at the connection end between the inner door handle 1 and the outer door handle. Since the inner door handle 1 and the armrest heating part 2 are hollow inside and filled with a carbon fiber heating element, wire connections are required. The setting of the outlet 4 is beneficial for the arrangement of wires, allowing the wires to pass through the inside of the inner door handle 1 and the outer door handle to avoid the exposure of the wires and affect the appearance.

[0040] As Figure 5 shown, this embodiment provides a push-pull shower door, including a push-pull door frame 5, a door leaf 51, and the heated door handle mentioned in the above embodiment. Specifically, a drag chain is provided on the door frame 5. When the door leaf 51 is pushed or pulled, the drag chain can prevent the wires from being repeatedly pulled and protect the wires.

[0041] As Figure 6 shown, this embodiment provides a side-hung shower door, including a side-hung door frame 5, a door leaf 51, and the heated door handle mentioned in the above embodiment.

[0042] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge possessed by those of ordinary skill in the art in the technical field to which it belongs, various changes can be made without departing from the purpose of the present invention.
