Description

Technical Field

[0001] This utility model relates to the field of indoor heating devices, and in particular to a bathroom heating device. Background Technology

[0002] Currently, the most common heating devices in bathrooms are the bathroom heaters installed on the ceiling and the fan heaters installed on the ceiling or suspended from the side wall. Bathroom heaters can be categorized into several types based on their heating principle, such as radiant heaters, fan heaters, and radiant-fan heaters. Installation methods include wall-mounted and ceiling-mounted. Fan heaters are commonly installed either fixed to the bathroom ceiling or portable. While bathroom heaters and fan heaters can raise the bathing temperature in home bathrooms during winter, they also present some problems: 1. Radial heaters primarily use radiant heating, and the strong light can easily damage the skin and eyes. Prolonged use of bathroom heaters to increase the bathroom temperature may also cause dizziness, lightheadedness, and other adverse symptoms; 2. When a fan heater is fixed to the ceiling or upper side wall of the bathroom and blows warm air downwards, the warm air generally only reaches the middle of the bathroom. This is because warm air ultimately moves upwards while cold air moves downwards, meaning the warm air blown by the fan heater can only reach a certain area. The upper half of the bather's body, i.e., the lower half, remains exposed to cold air. In fact, if the airflow from the heater is too strong, the bather will find it difficult to bear or adapt; if the airflow is too weak, it will be difficult to raise the temperature in the bathroom. Therefore, when the bather sprays hot water downwards, because the lower half of the bathroom has colder air compared to the upper half, while the upper body feels comfortable, the lower body will inevitably feel cold. If the lower body is not cold, the water temperature needs to be too high, making it unbearable for the upper body. 3. Portable heaters not only occupy limited space in the bathroom, but users are also easily exposed to them, posing a certain safety hazard. Summary of the Invention

[0003] The purpose of this invention is to provide a bathroom heating device that addresses the shortcomings of existing technologies and solves the problem of uneven heating in bathrooms.

[0004] The technical solution adopted in this utility model is as follows.

[0005] A bathroom heating device is characterized in that it includes several heating boxes, an opening sealing cover, a water tank, a main pipe, and several branch pipes. Each heating box has a core plate inside its cavity, and each heating box has a core plate inlet opening on its rear side. An opening sealing cover is movably connected to the core plate inlet opening. The top of the heating box has a protruding part. The upper and lower ends of the left side wall and the upper and lower ends of the right side wall of the protruding part each have a main pipe through hole.

[0006] Each heating box has a pipe through hole on each side of the protruding part on the top surface.

[0007] The main pipe passes through the highest main pipe through hole at each protrusion of each heating box and through the lowest main pipe through hole at each protrusion of each heating box. Both ends of the main pipe are connected to the water tank to form a closed water circulation loop. An electric heating device is connected between the water tank on the main pipe and the nearest heating box, and a water pump is installed on the electric heating device.

[0008] The core board is provided with branch pipe mounting slots, and a branch pipe is installed in each branch pipe mounting slot. The branch pipe passes through two branch pipe through holes in the heating box body where it is located. One end of each branch pipe is connected to the main pipe through a first valve located on the main pipe. The first valve is close to the main pipe through hole that is closest to the branch pipe and has the highest position. The other end of each branch pipe is connected to the main pipe through a second valve located on the main pipe. The second valve is close to the main pipe through hole that is closest to the branch pipe and has the lowest position.

[0009] The beneficial effects of this utility model are as follows: Each heating box is connected in series via a main pipe, ensuring that each heating box does not affect the others and facilitating replacement and maintenance; the number of heating boxes can be set according to heating needs, resulting in a simple structure, small footprint, and convenient installation on bathroom walls; hot water heated by an electric heating device enters each branch pipe through the highest through-hole of the main pipe passing through the protruding part of the heating box, and then the hot water from each branch pipe enters the water tank through the lowest through-hole of the main pipe passing through the protruding part of the heating box. Warm air entering the center of the bathroom floor automatically rises because its density is less than that of cold air. This automatically rising warm air then flows down along the perimeter of the bathroom to the floor, thus placing the bather entirely in warm air. This avoids the discomfort caused by airflow passing over the skin and also eliminates the harmful effects of strong light from the bathroom heater on the skin and eyes.

[0010] As a preferred technical solution, rubber sealing devices are provided on both sides of the top of the heating box, and the first valve and the second valve are both located inside a rubber sealing device.

[0011] This technical solution can prevent water leakage.

[0012] As a preferred technical solution, an electric heating device with a control valve is connected between the main water tank and the nearest heating box.

[0013] As a preferred technical solution, the core board is a plastic core board.

[0014] As a preferred technical solution, each core board has two main horizontal grooves in the inner cavity of the protruding part of its heating box, and the main pipe passes through each main horizontal groove.

[0015] Adopting this technical solution facilitates the installation of the main pipe.

[0016] As a preferred technical solution, the cross section of the cavity of the heating box body parallel to the opening sealing cover plate is in a "convex" shape, and the cross section of the core plate parallel to the opening sealing cover plate is in a "convex" shape.

Detailed Implementation

[0037] The present invention will now be further described in conjunction with the accompanying drawings and embodiments.

[0038] Example 1. As... Figure 1-16 As shown, a bathroom heating device is characterized by comprising two heating boxes 1, an opening sealing cover 2, a water tank 3, a main pipe 5, and two branch pipes 7. Each heating box 1 has a core plate 4 inside its cavity 15. Each heating box 1 has a core plate inlet opening 14 on its rear side, and the opening sealing cover 2 is movably connected to the core plate inlet opening 14. The top of each heating box 1 has a protruding portion 11. The upper and lower ends of the left side wall and the upper and lower ends of the right side wall of the protruding portion 11 each have main pipe through holes 12. Each heating box 1 has a branch pipe through hole 13 on each side of the protruding portion 11 on its top surface.

[0039] The main pipe 5 passes through the main pipe through-hole 12 at the highest position of the protruding portion 11 of each heating box 1 and passes through the main pipe through-hole 12 at the lowest position of the protruding portion 11 of each heating box 1, and both ends of the main pipe 5 are connected to the water tank 3 to form a closed water circulation loop; an electric heating device 6 is connected to the position on the main pipe 5 between the water tank 3 and the heating box 1 closest to the water tank, and a water pump is arranged on the electric heating device 6.

[0040] The core plate 4 is provided with branch pipe mounting grooves 41, each branch pipe mounting groove 41 is provided with a branch pipe 7, and the branch pipe 7 passes through the two branch pipe through-holes 13 of the heating box 1 where the branch pipe is located.

[0041] One end of each branch pipe 7 is connected to the main pipe through a first valve 8 arranged on the main pipe 5, and the first valve 8 is close to the main pipe through-hole 12 which is the closest to the branch pipe 7 and at the highest position; the other end of each branch pipe 7 is connected to the main pipe through a second valve 81 arranged on the main pipe 5, and the second valve 81 is close to the main pipe through-hole 12 which is the closest to the branch pipe 7 and at the lowest position.

[0042] As a preferred technical solution, rubber sealing devices 9 are respectively arranged on both sides of the top end of the heating box 1, and both the first valve 8 and the second valve 81 are located in one rubber sealing device 9.

[0043] Adopting this technical solution can prevent water leakage.

[0044] A control valve 61 is arranged at the position on the electric heating device 6 connected to the main pipe 5 between the water tank 3 and the heating box 1 closest to the water tank.

[0045] The core plate 4 is a plastic core plate.

[0046] Two main pipe transverse grooves 42 are arranged on the part of each core plate 4 located inside the inner cavity of the protruding portion 11 of the heating box 1 where the core plate is located, and the main pipe 5 passes through each main pipe transverse groove 42.

[0047] Adopting this technical solution facilitates the installation of the main pipe 5.

[0048] The cross section of the cavity 15 of the heating box parallel to the opening sealing cover plate 2 is in a "convex" shape, and the cross section of the core plate 4 parallel to the opening sealing cover plate 2 is in a "convex" shape.

Hot water heated by an electric heating device 6 flows through the highest through-hole 12 of the protruding portion 11 of the heating box 1 into each branch pipe 7 via the main pipe 5. The hot water then flows through each branch pipe 7 back into the water tank via the lowest through-hole 12 of the protruding portion 11 of the heating box 1. Warm air entering the center of the bathroom floor rises automatically because it is less dense than cold air. After reaching the top of the bathroom, the rising warm air flows down the perimeter to the floor, ensuring that the bather is surrounded by warm air. This avoids the discomfort caused by drafts on the skin and eliminates the harmful effects of strong light from the bathroom heater on the skin and eyes.
