Description

Hanging stove prevents frostbite and adopts hanging stove of this cover that prevents frostbite

Technical Field

The application relates to a hanging stove technical field, especially relates to hanging stove prevents frostbite and covers and adopts this hanging stove of preventing frostbite.

Background

When being installed, the traditional wall-mounted boiler is usually arranged indoors and is respectively connected with a gas pipeline, an air supply and exhaust smoke pipe, a heating water and domestic water inlet and outlet pipe. Because of the characteristics of internal combustion, smoke exhaust and multiple interface pipelines, the wall-mounted furnace can not be hidden in a wall cabinet, so that the indoor decoration effect is influenced and the wall-mounted furnace is subject to the scaling of users. Therefore, many users choose to place the wall-hanging stove outside the balcony, so as to avoid the water pipe, the air pipe and the smoke pipe from being exposed in the kitchen to influence the decoration effect.

However, the method has great potential safety hazard, and especially when a target customer is in an extremely cold area, important parts such as water inlet and outlet pipes and the like are easy to be frozen and leaked on a balcony outside the wall hanging furnace. Once meeting the situation, the wall-mounted stove can alarm and stop working, which brings great influence to the life of the user.

In the prior art, in order to solve the problems, a heating water loop of a wall-mounted boiler is usually matched with software anti-freezing logic, a water pump is started when the temperature of a heating water outlet is lower than a set value, forced combustion is ignited to heat water supply, and anti-freezing operation is stopped when the temperature of the heating water outlet is higher than a safe set value. However, the anti-freezing operation only aims at a heating water loop and cannot protect the domestic water inlet pipe and the domestic water outlet pipe, so that when the wall-mounted boiler is arranged outside a low-temperature chamber, the domestic water pipe cannot be prevented from being frozen and cracked.

Detailed Description

To assist those skilled in the art in understanding the subject matter claimed herein, specific embodiments thereof are described below in detail with reference to the accompanying drawings.

Referring to fig. 1 to 3, an anti-freezing cover 100 for a wall-hanging stove includes an anti-freezing cover main body 110 having a pipe receiving space 130, and a connecting member 120 disposed on the anti-freezing cover main body 110, wherein the anti-freezing cover main body 110 is attached to a wall-hanging stove housing 200 through the connecting member 120, and the pipe receiving space 130 receives a heating water outlet pipe 210, a domestic hot water outlet pipe 220, a gas inlet pipe 230, a tap water inlet pipe 240, and a heating water return pipe 250 protruding from the wall-hanging stove housing 200. Since these pipes are generally located at the bottom of the hanging stove housing 200, the anti-freeze cover 100 is also attached to the bottom of the hanging stove housing 200. It is understood that the covering area of the antifreeze cover 100 to the bottom of the wall-hanging stove housing 200 can be determined according to actual requirements (e.g., the size of space), as long as the aforementioned pipes are accommodated therein.

In some embodiments, the freeze shield body 110 is a housing having a fixed shape. The shape of the anti-freezing cover body 110 may be an extension similar to the shape of the wall-hanging stove housing 200 as shown in fig. 2, or may be a pipe accommodating space 130 having a stepped shape according to the length of the pipe as shown in fig. 3, so as to accommodate a heating water outlet pipe, a domestic hot water outlet pipe, a gas inlet pipe, a tap water inlet pipe, and a heating water return pipe, which have different lengths. The former has the advantage of stronger universality of the anti-freezing cover 100, and the latter has the advantages of more compact internal space of the pipeline accommodating space 130 and better heat preservation effect. In addition, since the back of the freeze protection cover is closely attached to the wall surface after the installation is completed, the freeze protection cover 100 may be manufactured as a case having only an open top as shown in fig. 2, or as a case having both an open top and a open back as shown in fig. 3, in various embodiments. In some embodiments, the freeze shield body 110 is made of an EPP material (polypropylene plastic foam). The EPP material is a high-crystallization polymer/gas composite material with excellent performance, has better compression-resistant buffering heat-insulating performance, can be recycled and can be naturally degraded without causing white pollution.

In order to meet the condition that some users are used to frequently switch on and off gas valves or need to use water replenishing valves, the anti-freezing cover body 110 is detachably attached to the bottom of the hanging stove housing 200 through the connecting member 120. Referring to fig. 2, for example, in the present embodiment, a permanent magnet is embedded in the surface of the anti-freezing cover body 110 contacting the bottom of the wall-hanging oven housing 200 as the connecting member 120, so that the anti-freezing cover 100 can be firmly attached to the bottom of the wall-hanging oven housing 200, which not only ensures that a user can easily detach and perform operations such as water replenishment and opening and closing of a ball valve during use, but also has a simple structure and is easy to operate. In other embodiments, the connecting member 120 may take a variety of forms. In order to ensure the heat-insulating and sealing effect, in some embodiments, a sealing ring (not shown) is further disposed at a connection portion between the anti-freezing cover main body 110 and the wall-hanging stove housing 200, and the sealing ring is made of, for example, flexible silicone.

In order to prevent the frost crack of the water pipe caused by the power supply of the wall-hanging stove being turned off by mistake in the low-temperature environment, in some embodiments, a temperature sensor (not shown) for detecting the temperature of the domestic hot water outlet pipe and the temperature of the tap water inlet pipe is further disposed in the anti-freezing cover 100, and the temperature sensor is electrically connected with the control unit. The control unit is a control unit which is independently arranged or uses the wall-mounted furnace, and the control unit (not shown) is also connected with an alarm unit (not shown). Thus, when the temperature sensor measures that the temperature of the wall of the water pipe is lower than a preset temperature, for example, 2 ℃, the alarm unit gives an alarm to remind a user that the power supply cannot be turned off and the heating water function must be turned on to prevent the pipe from being frozen. Such as a buzzer or other audible, visual, vibratory alert device, etc. The electrical connection of the temperature sensor, the control unit and the alarm unit is well known to those skilled in the art and will not be described herein.

It will be appreciated that the same technical effects can be obtained with a wall-hanging stove employing the wall-hanging stove anti-freeze cover as described above.

From this, this application has provided an outdoor hanging stove solution, and it can cooperate current hanging stove self software logic that prevents frostbite, reaches and does not influence the wholeness ability when arranging the hanging stove in outdoor, and has frostproofing, rain-proof effect concurrently. This application has utilized the waste heat that the heating hydrologic cycle (heating outlet pipe, heating wet return) self brought, gives the heat transfer to domestic water pipeline (domestic water outlet pipe, running water inlet tube) through convection heat transfer, radiant heat exchange. Even if the user does not use the domestic water, the water in the pipeline is kept static and does not flow, the domestic water pipe can be heated to more than 0 ℃ by applying the scheme, and the domestic water pipe is prevented from being frozen and cracked. According to verification, the scheme can support the environment temperature to be-30 ℃ at the lowest. The anti-freezing cover also has the effect of hiding the water pipe and the air pipe, so that the wall-mounted furnace is more attractive after being mounted.

Although the application has been illustrated and described herein with reference to specific embodiments, the application is not intended to be limited to the details shown. Rather, various details of the application may be modified within the scope and equivalents of the claims.
