Waterproof warmer

Abstract

This utility model discloses a waterproof heater, including a casing, a volute housed within the casing, and a heating element housed within the volute house. The casing has an air outlet, and the volute house has an opening on the side near the air outlet, which is connected to the air outlet. A water-blocking module is installed inside the volute house between the heating element and the air outlet. The water-blocking module includes multiple water-blocking plates arranged in a row within the volute house, with adjacent water-blocking plates forming a water-blocking ventilation channel. The water-blocking ventilation channel formed by the multiple water-blocking plates can, on the one hand, block external water, such as water vapor and water droplets in the bathroom, preventing it from directly entering the volute house from the air outlet and contacting the heating element, thus preventing short circuits, leakage, and other circuit failures caused by water ingress, thereby protecting the heating element and extending the life of the heater. On the other hand, while effectively blocking water, the water-blocking ventilation channel can still ensure normal air circulation, allowing the hot air from the heater to be blown out smoothly from the air outlet without affecting normal heating.

Description

Technical Field

[0001] This utility model relates to the field of heater technology, and in particular to a waterproof heater. Background Technology

[0002] Heaters are commonly used indoor heating devices in winter, widely applied in homes, offices, and other places, providing a warm and comfortable environment in cold weather. As people's living standards improve, the demand for heaters in various scenarios is becoming increasingly diverse, with bathroom heating gradually emerging as an important application. However, existing heaters generally suffer from design flaws, lacking a dedicated water-resistant structure.

[0003] When used in humid environments such as bathrooms, external water can easily enter the heater's casing through the air outlet due to steam from showering and spraying water. The casing typically houses heating elements; if these elements come into contact with water, it can cause short circuits, electrical leaks, and other circuit malfunctions. This not only damages the heating elements and affects the heater's normal operation, but in more serious cases, it can also lead to electric shocks and other safety hazards, endangering the user's life. Furthermore, water damage increases maintenance and replacement costs for users, reduces product lifespan, and negatively impacts the user experience. Therefore, existing heaters have significant shortcomings in waterproofing, and their structural design needs further improvement and optimization to meet users' needs for safe and reliable use in more scenarios. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a waterproof heater that can block water.

[0005] A waterproof heater designed for this purpose includes a housing, a volute housed inside the housing, and a heating element housed inside the volute house. The housing is provided with an air outlet. The volute house is opened on the side near the air outlet and communicates with the air outlet. A water-blocking module is provided inside the volute house between the heating element and the air outlet.

[0006] The water-blocking module includes multiple water-blocking plates arranged inside the volute, with water-blocking and ventilation channels formed between adjacent water-blocking plates.

[0007] Preferably, the water-blocking plate has a "C" shaped structure or a "∧" shaped structure.

[0008] Preferably, the water-blocking module further includes a fixed frame fixedly disposed within the volute, and the water-blocking plate is disposed on the fixed frame.

[0009] Preferably, the volute has an opening on the side away from the air outlet and is connected to a cover, and the cover is equipped with a fan for driving air into the volute.

[0010] Preferably, a drain outlet is provided at the bottom of the housing, and a drainage space communicating with the drain outlet is provided between the inner wall of the housing and the outer bottom wall of the volute.

[0011] The housing is provided with an air inlet, and a connecting space is provided inside the housing near the air inlet. The lower part of the connecting space is connected to the drainage space, and the upper part is connected to the inside of the volute.

[0012] Compared with existing technologies, this invention effectively solves the problem of water easily entering the volute and damaging the heating element in existing heaters due to the lack of a waterproof structure, by setting a water-blocking module inside the volute between the heating element and the air outlet. Specifically, the water-blocking ventilation channel formed by multiple arranged water-blocking plates can, on the one hand, block external water, such as water vapor and splashes in the bathroom, preventing it from directly entering the volute from the air outlet and contacting the heating element. This prevents short circuits, leakage, and other circuit failures caused by water ingress, thus protecting the heating element and extending the heater's lifespan. On the other hand, while effectively blocking water, the water-blocking ventilation channel still ensures normal air circulation, allowing the heater's hot air to be smoothly blown out from the air outlet without affecting the normal functioning of heating. In addition, this design greatly improves the safety of heater use, reduces the risk of electric shock and other safety accidents caused by water ingress, and enables the heater to be used safely and reliably in humid environments such as bathrooms, expanding the application scenarios of the heater and improving the user experience.

[0028] See Figures 1-7 A waterproof heater includes a housing 10, a volute 50 disposed within the housing 10, and a heating element 20 disposed within the volute 50. The housing 10 is provided with an air outlet 110. The volute 50 is opened on the side near the air outlet 110 and communicates with the air outlet 110. A water-blocking module 30 is disposed within the volute 50 between the heating element 20 and the air outlet 110. The water-blocking module 30 includes multiple water-blocking plates 310 arranged within the volute 50, and a water-blocking ventilation channel 320 is formed between two adjacent water-blocking plates 310. The water-blocking ventilation channel formed by multiple arranged water-blocking plates can, on the one hand, block external water, such as water vapor and water droplets in the bathroom, preventing it from directly entering the casing from the air outlet and contacting the heating element. This prevents short circuits, leakage, and other circuit failures caused by water ingress, thus protecting the heating element and extending the life of the heater. On the other hand, while effectively blocking water, the water-blocking ventilation channel can still ensure normal air circulation, allowing the heater's hot air to be blown out smoothly from the air outlet without affecting the normal operation of the heating function.

[0029] In this invention, the water-blocking plate 310 has a "C"-shaped structure. When external water enters the volute from the air outlet, it encounters the "C"-shaped water-blocking plate. Due to its special structure, the water flows to both sides along the arc-shaped guide plate and eventually slides down the side of the water-blocking plate to the bottom of the volute, unable to pass over the water-blocking plate and enter the area where the heating element is located. At the same time, air can flow smoothly through the tortuous channels formed between the water-blocking plates, without affecting the normal air supply and heating function of the heater.

[0030] In this invention, the water-blocking plate 310 has a "∧" shaped structure. When water droplets enter the volute from the air outlet, they impact the inclined surface of the "∧" shaped water-blocking plate. Under the influence of gravity and the angle of the inclined surface, the water droplets slide down the inclined surface to the bottom of the volute, effectively preventing water droplets from splashing onto the heating element. Air can then flow within the channel formed by the "∧" shaped water-blocking plate, smoothly transferring the heat generated by the heating element and ensuring the heating effect of the heater.

[0031] See Figure 3 The water-blocking module 30 also includes a fixed frame 330 fixedly installed inside the volute 50, and the water-blocking plate 310 is installed on the fixed frame 330.

[0032] See Figure 2 and Figure 3 The volute 50 has an opening on the side away from the air outlet 110 and is connected to a cover 500. The cover 500 is equipped with a fan 40 for driving air into the interior of the volute 50.

[0033] See Figure 4 and Figure 6 The casing 10 has a drain outlet 130 at its bottom, and a drainage space 120 communicating with the drain outlet 130 is provided between the inner wall of the casing 10 and the outer bottom wall of the volute 50. The casing 10 has an air inlet 100, and a connecting space 140 is provided inside the casing 10 near the air inlet 100. The lower part of the connecting space 140 communicates with the drainage space 120, and the upper part communicates with the interior of the volute 50. The purpose of this design is that when external water enters the casing 10 from the air inlet, the water will first enter the connecting space 140, and then, under the action of gravity, the water will flow downward into the drainage space 120, and then be discharged to the outside through the drain outlet 130, thus playing a certain role in waterproofing and drainage.

[0034] See Figure 7 The surface of the volute 50 below the water-blocking module 30 is a guide slope 501, which is inclined toward the air outlet 110. The guide slope 501 prevents water from flowing from the outside to the inside, and at the same time guides the water entering the volute toward the air outlet 110.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
